    Indisputably, search engines (SEs) abound. The monumental growth of users performing online searches on the Web is a contending issue in the contemporary world nowadays. For example, there are tens of billions of searches performed everyday, which typically offer the users many irrelevant results which are time consuming and costly to the user. Based on the afore-going problem it has become a herculean task for existing Web SEs to provide complete, relevant and up-to-date information response to users' search queries. To overcome this problem, we developed the Distributed Search Engine Architecture (DSEA), which is a new means of smart information query and retrieval of the World Wide Web (WWW). In DSEAs, multiple autonomous search engines, owned by different organizations or individuals, cooperate and act as a single search engine. This paper includes the work reported in this research focusing on development of DSEA, based on topic-specific specialised search engines. In DSEA, the results to specific queries could be provided by any of the participating search engines, for which the user is unaware of. The important design goal of using topic-specific search engines in the research is to build systems that can effectively be used by larger number of users simultaneously. Efficient and effective usage with good response is important, because it involves leveraging the vast amount of searched data from the World Wide Web, by categorising it into condensed focused topic -specific results that meet the user's queries. This design model and the development of the DSEA adopt a Service Directory (SD) to route queries towards topic-specific document hosting SEs. It displays the most acceptable performance which is consistent with the requirements of the users. The evaluation results of the model return a very high priority score which is associated with each frequency of a keyword.

  3. Architecture as Ars Combinatoria

    Full Text Available Architecture today, no longer reflects the limits of experimentation and innovation. An extremely low-tech art whose field of possibilities consists of choosing and using that which has already been done in the past. It is because of this that the key skill a designer should have is the ability to recognize the complexity in forms around them: cities have the widest programming opportunities for architecture, in the two-way relationship that is established from the city that takes form in architecture and an architecture that finds its place in the contemporary city. Thus, architecture has its foundation in hospitality, an element that differentiates it significantly from the design.

    Full Text Available There is an urgent need for new antibiotics and alternative strategies to combat multidrug-resistant bacterial pathogens, which are a growing clinical issue. Repurposing existing approved drugs with known pharmacology and toxicology is an alternative strategy to accelerate antimicrobial research and development. In this study, we show that celecoxib, a marketed inhibitor of cyclooxygenase-2, exhibits broad-spectrum antimicrobial activity against Gram-positive pathogens from a variety of genera, including Staphylococcus, Streptococcus, Listeria, Bacillus, and Mycobacterium, but not against Gram-negative pathogens. However, celecoxib is active against all of the Gram-negative bacteria tested, including strains of, Acinetobacter, and Pseudomonas, when their intrinsic resistance is artificially compromised by outer membrane permeabilizing agents such as colistin. The effect of celecoxib on incorporation of radioactive precursors into macromolecules in Staphylococcus aureus was examined. The primary antimicrobial mechanism of action of celecoxib was the dose-dependent inhibition of RNA, DNA, and protein synthesis. Further, we demonstrate the in vivo efficacy of celecoxib in a methicillin-resistant S. aureus (MRSA infected Caenorhabditis elegans whole animal model. Topical application of celecoxib (1 and 2% significantly reduced the mean bacterial count in a mouse model of MRSA skin infection. Further, celecoxib decreased the levels of all inflammatory cytokines tested, including tumor necrosis factor-α, interleukin-6, interleukin-1 beta, and monocyte chemo attractant protein-1 in wounds caused by MRSA infection. Celecoxib also exhibited synergy with many conventional antimicrobials when tested against four clinical isolates of S. aureus. Collectively, these results demonstrate that celecoxib alone, or in combination with traditional antimicrobials, has a potential to use as a topical drug for the treatment of bacterial skin infections.

    Full Text Available The tasks and goals of architecture are the same, today as in the past. What has changed are the conditions by which we reach them. The broadest phenomenon of the city has always been the presence and the simultaneity of public and private life. We live not only in private dwellings and buildings, but also in public streets and squares. Basically the house is an object. Each construction element, each architectural detail, is an object, which has to be designed. However, it is crucial in architecture that each architectural element is part of the construction in its entirety. The notion of the architectural profession must be reached through its Anschauung and reality is definitely the best school for our profession.

Tazarotene exerts anti-inflammatory and immune-modulating activities toward both infective agents and damaged keratinocytes. Given the well-documented efficacy of tazarotene on hyperkeratotic nail psoriasis, we investigated its therapeutic use in onychomycosis. Patients and methods: We designed a preliminary open clinical trial in patients affected by distal and lateral subungual onychomycosis of the toenails and verified the fungistatic activity of tazarotene in vitro. Fifteen patients were treated with topical tazarotene 0.1% gel once per day for 12 weeks. Mycological cultures and potassium hydroxide stains of nail samples were performed at the beginning and at the end of the study. Treatment was considered effective when clinical healing and negative mycological culture were obtained. Onycholysis, nail bed discoloration, and subungual hyperkeratosis were measured using standardized methodologies and analyzed by means of Mann–Whitney test and analysis of variance. Fungistatic activity of tazarotene was evaluated by disk diffusion assay. Results: Six patients (40% reached a mycological cure on target nail samples already after 4 weeks of treatment. Complete clinical healing and negative cultures were reached in all patients at week 12, with a significant improvement of all clinical parameters of the infected nails.

    2013-09-01

    Full Text Available The concept of sustainability and a sustainable and ecological development are common debate topics in today’s society. This paper discusses the concept of sustainability in green building with regard to schools. The research was conducted on a representative sample of primary school teachers, focusing on some of their opinions on green building. We asked them which aspect of building they favoured and how often they asked themselves certain questions about the school they taught in. Furthermore, we were interested to see whether we would find age-related differences. To this end, teachers were divided into two groups, namely, teachers of up to 35 years of age and teachers over 35. We were surprised to find that teachers over 35 had a more positive attitude towards green building in schools compared to their younger colleagues. Based on the results, we came to a conclusion that the topics pertaining to ecology and sustainable development are neglected in today’s education. However, making them part of school curriculum is not enough, as the opinions and attitudes of teachers on sustainable and ecological issues also have an important impact on the subject-matter itself.

    Full Text Available Environmental psychology categorizes “physicalenvironment” as “typically neutral,” only coming into selfconscious awareness when individuals form stable andenduring representations of it [1]. We see this manifest inthe real world when the steeple of a church is able to communicate that it is a place for reflection and religious gathering; the bricks and ivy of Harvard Yard signifies years of scholarly research and education; the solid grey walls ofa prison conjures up images of torture and punishment; and the bright colors of a playground indicates play and joyfulness. In our relationship with architecture, we are ableto construct an understanding of our environment becausewe pick up such clues and cues from parts of ourenvironment and then construct a formulation of the whole based on our memories and knowledge. Thus, we are ableto communicate with the places we live in and the placeswe live in are able to act as interfaces for information interchange.

  20. LIQUID CRYSTAL AS ACCELERANT IN DRUG ABSORPTION FROM TOPICAL FORMULATIONS

    2011-04-01

    Full Text Available Topical drug delivery has been one of the major research fields in the area of drug therapy for last few decades. However inspite of its large therapeutic potential market success has been limited. It provides the several advantages over the oral drug delivery. Percutaneous absorption involves the passage of the drug molecule from the skin surface into the stratum corneum under the influence of a concentration gradient and its subsequent diffusion through the stratum corneum and underlying epidermis, through the dermis, and into the blood circulation. Liquid crystal phase has emerged as a novel material for preparation of topical drug delivery systems. It fulfills the requirements for making drug loading and drug absorption faster from the site of application of topical formulations. Liquid crystal has got many phases in itself which can be further exploited to get a better and more efficient drug delivery system. Also a variety of areas in medical and electronics streamline can find its application. There is also a wide scope in respect to the methods by which these liquid crystals can be prepared. Different methods give rise to different kinds of liquid crystals. Topical formulations have emerged as a very useful drug delivery system as it bypasses the first pass metabolism. Also the absorption of drugs depends on the percutaneous absorption of drug from the area of application. Hence it’s required to choose such a vehicle which enhances the absorption of drug from the formulation.

  7. Elastic vesicles as topical/transdermal drug delivery systems.

    Choi, M J; Maibach, H I

    2005-08-01

    Skin acts a major target as well as a principle barrier for topical/transdermal drug delivery. Despite the many advantages of this system, the major obstacle is the low diffusion rate of drugs across the stratum corneum. Several methods have been assessed to increase the permeation rate of drugs temporarily. One simple and convenient approach is application of drugs in formulation with elastic vesicles or skin enhancers. Elastic vesicles are classified with phospholipid (Transfersomes((R)) and ethosomes) and detergent-based types. Elastic vesicles were more efficient at delivering a low and high molecular weight drug to the skin in terms of quantity and depth. Their effectiveness strongly depends on their physicochemical properties: composition, duration and application volume, and entrapment efficiency and application methods. This review focuses on the effect of elastic liposomes for enhancing the drug penetration and defines the action mechanism of penetration into deeper skin. PMID:18492190

    2002-06-01

    This paper takes into consideration the role of color as a non-verbal language between human beings and the environment. The communication is based on the function of the color vision to separate and identify. A language about color can be based on the same. The concept behind the Natural Color System is color differentiation and color identification, which I find very useful both in color education of design students and in environmental color design work. A commission to plan the exterior use of color for a whole mining town on 78 degree(s) North in Longyearbyen, Spitsbergen, will illustrate my ideas. This will serve as an example of how these different 'languages' can work together. After a twenty years ongoing process this work is now almost fulfilled and the result will be shown in the presentation.

    This book sets out the conditions in which the need for a new approach to the production of architecture in the twenty-first century is established, where our homes and cities are facing increasing pressures from environmental challenges that are compromising our well being and our lives. Vibrant architecture embodies a new kind of architectural design practice that explores how lively materials, or ‘vibrant matter’ may be incorporated into our buildings to confer on them some of the properties of living things such as, movement, growth, sensitivity and self-repair. My research examines the theoretical and practical implications of how this may occur through the application of a new group of materials in the production of our living spaces, collectively referred to as ‘vibrant matter’.

    Full Text Available There are many crawling systems available on the market but they are rather close systems dedicated for performing particular kind and class of tasks with predefined set of scope, strategy etc. In real life however there are meaningful groups of users (e.g. marketing, criminal or governmental analysts requiring not just a yet another crawling system dedicated for performing predefined tasks. They need rather easy-to-use, user friendly all-in-one studio for not only executing and running internet robots and crawlers, but also for (graphical (redefining and (recomposing crawlers according to dynamically changing requirements and use-cases. To realize the above-mentioned idea, Cassiopeia framework has been designed and developed. One has to remember, however, that enormous size and unimaginable structural complexity of WWW network are the reasons that, from a technical and architectural point of view, developing effective internet robots – and the more so developing a framework supporting graphical robots’ composition – becomes a really challenging task. The crucial aspect in the context of crawling efficiency and scalability is concurrency model applied. There are two the most typical concurrency management models i.e. classical concurrency based on the pool of threads and processes and event-driven concurrency. None of them are ideal approaches. That is why, research on alternative models is still conducted to propose efficient and convenient architecture for concurrent and distributed applications. One of promising models is staged event-driven architecture mixing to some extent both of above mentioned classical approaches and providing some additional benefits such as splitting application into separate stages connected by events queues – what is interesting taking requirements about crawler (recomposition into account. The goal of this paper is to present the idea and the PoC  implementation of Cassiopeia framework, with the special

  15. Comparative Study between topical applications liposomally entrapped DNA repair enzymes and thymidine dinucleotide as radioprotectors

    International Nuclear Information System (INIS)

    The delivery of active agents to the skin by liposome carriers received great interest during the last three decades. This is based on their potential to enclose various types of biological materials and to deliver them to diverse cell types. Recent work suggests that liposomes as vehicles for topical drug delivery may be superior to conventional preparations. Also, topical application of DNA repair enzymes to irradiated skin increases the rate of repair of DNA potentially damaged cells. Moreover, thymidine dinucleotide is a new skin photo-protective agent against non-ionizing radiation through induction of DNA repair. Gamma irradiation can produce DNA damage in human skin. DNA mutations have an important role in the development of skin cancer and precancerous skin lesions. Albino rats were irradiated with Cobalt-60 gamma radiation with different doses (0.5, 1.5, 3 Gy), and were treated by either thymidine dinucleotide or liposomally entrapped DNA repair enzymes topically 24 hours before irradiation. Evaluation was done histopathologically by H and E stain. Computerized image analyzer using Masson's trichrome stain was also done. Gamma radiation produced epidermal thinning and dermal inflammatory cells together with collagen fragmentation and clumping in a dose-dependent manner. Comparing between both thymidine dinucleotide and liposomally entrapped DNA repair enzymes pretreated and irradiated rats. Low dose irradiation (0.5 Gy) together with previous drugs showed preservation of epidermis with no inflammatory cells and also it maintained the normal architecture of collagen bundles. However, they were ineffective with higher doses. In conclusion our results may suggest that the effects of gamma radiation on the skin at low dose could be minimized by the use of these drugs before exposure

New insights on the typology of industrial architecture are reviewed (e. g. global changes in all European industry, new concepts and technologies in manufacturing, new features of industrial architecture and their construction and typology, first results of industrialization and changes in the typology of industrial architecture in post-industrial period. General goals and tasks of conservation in context of adaptive reuse of industrial heritage architecture are defined (e. g. historical, architectural and artistic, technical. Adaptive reuse as an acceptable approach for conservation and new use is proposed and reviewed. Moreover, the logical model of adaptive reuse of industrial heritage architecture as an acceptable approach for new use has been developed. Consequently, three general methods for the conservation of industrial heritage architecture by the adaptive reuse approach are developed: historical, architectural and artistic, technical. Relevant functional methods' concepts (social concepts are defined and classified. General beneficial effect of the adaptive reuse approach is given. On the basis of analysis results of experience in adaptive reuse of industrial architecture with new social functions general conclusions are developed.

    Dynamic Field Theory (DFT) is an established framework for modeling embodied cognition. In DFT, elementary cognitive functions such as memory formation, formation of grounded representations, attentional processes, decision making, adaptation, and learning emerge from neuronal dynamics. The basic computational element of this framework is a Dynamic Neural Field (DNF). Under constraints on the time-scale of the dynamics, the DNF is computationally equivalent to a soft winner-take-all (WTA) network, which is considered one of the basic computational units in neuronal processing. Recently, it has been shown how a WTA network may be implemented in neuromorphic hardware, such as analog Very Large Scale Integration (VLSI) device. This paper leverages the relationship between DFT and soft WTA networks to systematically revise and integrate established DFT mechanisms that have previously been spread among different architectures. In addition, I also identify some novel computational and architectural mechanisms of DFT which may be implemented in neuromorphic VLSI devices using WTA networks as an intermediate computational layer. These specific mechanisms include the stabilization of working memory, the coupling of sensory systems to motor dynamics, intentionality, and autonomous learning. I further demonstrate how all these elements may be integrated into a unified architecture to generate behavior and autonomous learning. PMID:24478620

    Full Text Available With the rapid development and integration of the Internet, wireless communication network and the Internet of Things, the Internet faces many challenges as a bearer network: a large volume of information exchange, multi-level QoS and smoothly switching multiple access protocols.The Internet should be able to provide a variety of network capacities in a more dynamic and on-demand way, not just limited network resource provision through virtualization. The elastic network is expected to adapt to network changes by enabling network protocols selection and combination dynamically. Cloud computing illustrates a new Internet-based model of IT resources (hardware, software, data provision, delivery and consumption as a service. Therefore, networking as a service can provide guaranteed quality of service and good quality of experience to users who do not care about any network configuration and network management.In this paper, we propose a novel idea of networking as a service by combining the service provision model of cloud computing with the openness of the network protocol. The related conception and stakeholders of networking as a service is depicted. Cloud-based network architecture is design to present the provision, delivery and consumption of networking as a service and discuss the key features of cloud-based network. Finally, a prototype of cloud-based network is implemented by extending OpenFlow architecture.

    2013-01-01

    We study the Florida high-voltage power grid as a technological network embedded in space. Measurements of geographical lengths of transmission lines, the mixing of generators and loads, the weighted clustering coefficient, as well as the organization of edge conductance weights show a complex architecture quite different from random-graph models usually considered. In particular, we introduce a parametrized mixing matrix to characterize the mixing pattern of generators and loads in the Florida Grid, which is intermediate between the random mixing case and the semi-bipartite case where generator-generator transmission lines are forbidden. Our observations motivate an investigation of optimization (design) principles leading to the structural organization of power grids. We thus propose two network optimization models for the Florida Grid as a case study. Our results show that the Florida Grid is optimized not only by reducing the construction cost (measured by the total length of power lines), but also throug...

    Full Text Available The mosque is an integral part of the circuit-worship rituals of Islam. For Muslims in Indonesia, the role of the mosque as a place of worship, examines religion and some other activities occupy a strategic position not only as a religious symbol but more emphasis on the function of the space as a public building. Utilization of space in public buildings as well as space-ritual-social space will have meaning for the people in view of adaptation space used. Awareness of the importance of effective space utilization and management of water resources wisely in support of the ritual apply the principles of sustainable architecture will have a positive impact for the people to give directions as to how the principle of austerity-not wasteful in Islam can be applied. This paper will discuss about the process of continuous learning from the essence of understanding of the mosque as a model in implementing the process of life, taking into account the principles of simplicity, functional and wisdom, especially in the efficiency of utilization of local resources. The method used in this research is qualitative descriptive, which is explained the theory and based on literature and accompanied by case study that have implemented the principles. The output of this application of the principles of sustainable architecture in the planning and use of mosques as a place in the relationship with God and with fellow human relations can be a model for the faithful to deal with wisely challenge natural resource constraints, especially for future generations.

    Full Text Available Wesley K Lew1, Fred A Weaver21University of Southern California, Department of Surgery, Los Angeles, CA, USA; 2CardioVascular Thoracic Institute at the University of Southern California, Los Angeles, CA, USAAbstract: When surgical ligation of bleeding fails, or is not possible, surgeons rely on a number of hemostatic aids, including thrombin. This review discusses the history, pharmacology and clinical application of thrombin as a surgical hemostat. The initial thrombin was bovine in origin, but its use has been complicated by the formation of antibodies that cross react with human coagulation factors. This has been associated with life threatening bleeding and in some circumstances anaphylaxis and death. Human thrombin, isolated from pooled plasma of donors, has been developed in an effort to minimize these risks, but its downside is the potential of transmitting blood-borne pathogens and limited availability. Recently a recombinant thrombin has been developed and approved for use by the FDA. It has the advantage of being minimally antigenic and devoid of the risk if viral transmission. Thrombin is often used in conjunction with other hemostatic aids, including absorbable agents (like gelfoam, collagen, and cellulose, and with fibrinogen in fibrin glues. The last part of this review will discuss these agents in detail, and review their clinical applications.Keywords: bovine, recombinant, human, thrombin, antigenicity, antibodies

    Compared with systemic antibiotic therapy, the topical or local delivery of an antibiotic has many potential advantages. However, local antibiotics at the surgical site have received very limited approval in any of the surgical prophylaxis consensus guidelines that we are aware of. A review of the literature was carried out through searches of peer-reviewed publications in PubMed in the English language over a 30 year period between January 1980 and May 2010. Both retrospective and prospective studies were included, as well as meta-analyses. With regard to defining \\'topical\\' or \\'local\\' antibiotic application, the application of an antibiotic solution to the surgical site intraoperatively or immediately post-operatively was included. A number of surgical procedures have been shown to significantly benefit from perioperative topical prophylaxis, e.g. joint arthroplasty, cataract surgery and, possibly, breast augmentation. In obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. The selective use of topical antibiotics as surgical prophylaxis is justified for specific procedures, such as joint arthroplasty, cataract surgery and, possibly, breast augmentation. In selective cases, such as obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. Apart from these specific indications, the evidence for use of topical antibiotics in surgery is lacking in conclusive randomized controlled trials.

The proposed methodmakes system have low cost and wide availability, high scaling and inter-operating ability to allow the clients andserver objects, written in different languages, run in different operating system, and connected in different net-work to inter-operate. It also makes system easy to be extended and integrated with the other technologies andapplications distributed over the Internet. Using CORBA as a communication architecture, we developed hard-ware base, task-level robot arm control server, live image feedback server and mobile robot control server,which can provide some basic care services to aid the aged and disabled.

  16. Remote handling of TEXTOR diagnostics using CORBA as communication architecture

    International Nuclear Information System (INIS)

    At the Forschungszentrum Juelich, an upgrade of the existing distributed system for data acquisition (DAS) at the fusion experiment TEXTOR94 is under development. DAS is currently restricted to VAX/VMS and DECNET based communications, but it is planned to add UNIX based systems, and to open the local network for an improved wide area network access for remote operations. Therefore, the DAS system is to be equipped with a suitable client/server interface, which is able to cope with the various computer platforms and operating systems involved. For this purpose, the common object request broker architecture (CORBA) will be used. CORBA is an object oriented, standardized architecture for distributed systems, which provides a high degree of modularity in software design and allows for flexible implementations. It is to act as a connecting link between the existing system and new extensions. In order to provide the desired client/server functionality for the data acquisition tasks, the components of the system (diagnostic, database, etc.) are modelled by CORBA interfaces. Processes for diagnostic control and data readout in the existing OpenVMS systems are aimed at to be accessible by CORBA server implementations. The corresponding client implementations will be developed for the operating system platforms most frequently used at TEXTOR94. Communication between clients and server will be based on TCP/IP and are to be managed by CORBA. By this standardized way, remote control of diagnostic instrumentation becomes possible in a multiplatform computer and wide area network environment. At a later stage it is intended to integrate the system into a 'virtual control room' environment, which should enable the participation of cooperating institutions in the full experimental program of TEXTOR94.

A 9-year-old Malay girl with a history of bilateral blepharokeratoconjunctivitis was regularly treated with lid scrubbing using diluted baby shampoo, fusidic acid gel, and topical steroids as well as an intermittent course of oral doxycycline for the past year. She developed acute onset bilateral eye redness associated with poor vision in her right eye. Both eyes showed marked diffuse hyperemic conjunctiva with corneal vascularization. The presence of corneal vascularization obscured the visual axis in the right eye. The condition did not improve with regular intensive lid hygiene using diluted baby shampoo, fusidic acid gel, and topical steroids. She was started on topical cyclosporin A 0.5% every 6 hours. There was a dramatic regression of corneal vascularization after 3 days on topical cyclosporin, with marked improvement in visual acuity. This is a single case in which cyclosporin improved the status of the ocular surface. A large cohort study is required to justify its effectiveness in treating blepharokeratoconjunctivitis and to test its potential as an alternative immunosuppressive agent in comparison to conventional corticosteroids.Keywords: blepharokeratoconjunctivitis, cyclosporin

    Systems and Processes Engineering Corporation (SPEC) has developed an innovative array processor architecture for computing Fourier transforms and other commonly used signal processing algorithms. This architecture is designed to extract the highest possible array performance from state-of-the-art GaAs technology. SPEC's architectural design includes a high performance RISC processor implemented in GaAs, along with a Floating Point Coprocessor and a unique Array Communications Coprocessor, also implemented in GaAs technology. Together, these data processors represent the latest in technology, both from an architectural and implementation viewpoint. SPEC has examined numerous algorithms and parallel processing architectures to determine the optimum array processor architecture. SPEC has developed an array processor architecture with integral communications ability to provide maximum node connectivity. The Array Communications Coprocessor embeds communications operations directly in the core of the processor architecture. A Floating Point Coprocessor architecture has been defined that utilizes Bit-Serial arithmetic units, operating at very high frequency, to perform floating point operations. These Bit-Serial devices reduce the device integration level and complexity to a level compatible with state-of-the-art GaAs device technology.

    Full Text Available Creative activity is one of the most significant parts of architectural education. In the architectural curriculum organisation ‘design studio’ is the unique and preeminent subject. Freshman students encounter ‘design’ first in basic design course, before they know what designing incorporates. The Basic Design is the starting point of initiating creativity in architecture education. It helps each student to understand architecture as a creative and innovative practice in the first year of education. This study analyzes the characteristics of basic design course, the topics of the course contents and its significance in the architectural curriculum in Turkey as well.

    Topical administration of celecoxib proved to be an effective mean of preventing skin cancer development and improving anticancer drugs effectiveness in skin tumors treatment. The aim of this study was the development of an effective topical formulation of celecoxib, able to promote drug skin delivery, providing its in depth penetration through the skin layers. Three kinds of vesicular formulations have been investigated as drug carriers: liposomes containing a surfactant, or transfersomes and ethosomes, containing suitable edge activators. Firstly, the effect of membrane composition variations on the system performance has been evaluated for each vesicle type. Selected formulations were characterized for particle size, polydispersity index and encapsulation efficiency. The best formulations were subjected to ex vivo permeation studies through excised human skin. All vesicular formulations markedly (p ethosomes, respectively. In particular, ethosomes containing Tween 20 as edge activator not only showed the best vesicle dimensions and homogeneity, and the highest encapsulation efficacy (54.4%), but also enabled the highest increase in drug penetration through the skin, probably due to the simultaneous presence in their composition of ethanol and Tween 20, both acting as permeation enhancers. Therefore, among the various vesicular formulations examined in the study, Tween 20-ethosomes can be considered the most promising one as carrier for topical celecoxib applications aimed to prevent skin cancer development and increase the anticancer drugs effectiveness against skin tumors.

    This paper presents an architecture for satellites regarded as intercommunicating agents. The architecture is based upon a postmodern paradigm of artificial intelligence in which represented knowledge is regarded as text, inference procedures are regarded as social discourse and decision making conventions and the semantics of representations are grounded in the situated behaviour and activity of agents. A particular protocol is described for agent participation in distributed search and retrieval operations conducted as joint activities.

    Present study was taken up to develop a topical formulation that releases the drug in controlled manner, reduce the side effects associated with topical drug delivery and improve product efficacy with aid of microsponges. Microsponges loaded with sertaconazole nitrate were prepared by using quasi emulsion solvent diffusion with five different proportions of the polymer (Eudragit RS 100). The developed microsponges were analyzed for particle size, production yield, entrapment efficiency and drug content. Scanning electron microscopic images of microsponges revealed that they are spherical in shape and contain pores. Pore structure analysis was done by using mercury intrusion porosimetry technique, which confirmed the porous nature of microsponges. Microsponges were then incorporated in to a 1% corbopol gel and evaluated for pH, drug content, texture profile analysis and in vitro drug release. The batch F IV was found to be optimal as it shown 69.38% controlled drug release in 8 h that followed Higuchi model. PMID:26997694

    This work was undertaken to investigate microemulsion (ME) as a topical delivery system for the poorly water-soluble voriconazole. Different ME components were selected for the preparation of plain ME systems with suitable rheological properties for topical use. Two permeation enhancers were incorporated, namely sodium deoxycholate or oleic acid. Drug-loaded MEs were evaluated for their physical appearance, pH, rheological properties and in vitro permeation studies using guinea pig skin. MEs based on polyoxyethylene(10)oleyl ether (Brij 97) as the surfactant showed pseudoplastic flow with thixotropic behavior and were loaded with voriconazole. Jojoba oil-based MEs successfully prolonged voriconazole release up to 4 h. No significant changes in physical or rheological properties were recorded on storage for 12 months at ambient conditions. The presence of permeation enhancers favored transdermal rather than dermal delivery. Sodium deoxycholate was more effective than oleic acid for enhancing the voriconazole permeation. Voriconazole-loaded MEs, with and without enhancers, showed significantly better antifungal activity against Candida albicans than voriconazole supersaturated solution. In conclusion, the studied ME formulae could be promising vehicles for topical delivery of voriconazole. PMID:21696340

    Full Text Available Metal ion coordination in discrete or extended metallo-supramolecular assemblies offers ample opportunity to fabricate and study devices and materials that are equally important for fundamental research and new technologies. Metal ions embedded in a specific ligand field offer diverse thermodynamic, kinetic, chemical, physical and structural properties that make these systems promising candidates for active components in functional materials. A key challenge is to improve and develop methodologies for placing these active modules in suitable device architectures, such as thin films or mesophases. This review highlights recent developments in extended, polymeric metallo-supramolecular systems and discrete polyoxometalates with an emphasis on materials science.

    International Nuclear Information System (INIS)

    We report on the functional results of ortho topic modified T pouch ileal neo bladder, incorporating serous- lined extra mural ileal anti reflux technique for urinary diversion after radical cystectomy. Material and Methods: From September 1998 through November 2001,42 patients of mean age 49 years (range 45-54) having invasive bladder carcinoma underwent radical cystectomy and ortho topic ileal neo bladder urinary diversion, the modified T pouch. Thirty-three patients were males while the remaining 9 were females. The mean follow up was 24 months (range 18-42). Preoperative unior bilateral ureteral dilatation was noted in 13/42 (30.9%) patients). Follow up included clinical examination, laboratory, radiological and uro dynamic investigations. Early postoperative complications were recorded in 3 cases, that were managed conservatively. Day and night continence were achieved in 34/42 (81 %) and 29/42 (69%) patients, night enuresis in 2 (4.8%),while satisfactory day and night continence were noted, respectively. Upper urinary tract (UUT) remained unchanged or improved in all cases. No need for clean intermittent catherization (CIC). No evidence of reflux was detected. Pressure at maximum capacity (average 17 cm H2O at 600 ml). Mean flow rate was 17.6 ml/sec (range 15-24). Pelvic cancer recurrence was recorded in 5 patients at mean 24 months, respectively. Modified T pouch has an excellent functional criteria as an ortho topic ileal neo bladder reservoir. It is absolutely indicated in short and/or massively dilated ureter

  1. Systemic absorption of topical steroids. Metabolic effects as an index of mild hypercortisolism.

    1986-09-01

    This study was undertaken to determine whether the commonly used treatment of psoriasis with potent topical glucocorticoids results in hypercortisolism and whether metabolic changes might provide a means for monitoring pharmacologic effects of excessive systemic absorption of glucocorticoids. Plasma cortisol, glucose, and insulin and circulating polymorphonuclear leukocytes were assessed under controlled conditions in five otherwise healthy patients with psoriasis (40% to 85% involvement) treated with topical desoximetasone, without occlusion. In all patients, there were rapid and sustained suppression of endogenous cortisol production, twofold to threefold increases in fasting insulin levels indicating insulin resistance, and elevated levels of polymorphonuclear leukocytes. Two patients also experienced reduced glucose tolerance. These findings suggest that application of potent corticosteroids to large areas of diseased skin results in sufficient systemic absorption to cause not only adrenal suppression but some degree of hypercortisolism with greater frequency and rapidity than has been suggested. Prospective monitoring of insulin-glucose relationships as a sensitive index of the metabolic effects of glucocorticoids may provide a means of assessing excess systemic absorption that is not predictable on the basis of adrenal suppression or circulating levels of the drug. Such prediction could have particular relevance in anticipating adverse clinical effects in the treatment of chronic skin disorders with potent topical glucocorticoids. PMID:3527074

    The onset and development of the Asian monsoon systems is a topic that has attracted considerable research effort but proxy data limitations, coupled with a diversity of definitions and metrics characterizing monsoon phenomena, have generated much debate. Failure of geological proxies to yield metrics capable of distinguishing between rainfall seasonality induced by migrations of the Inter-tropical Convergence Zone (ITCZ) from that attributable to topographically modified seasonal pressure reversals has frustrated attempts to understand mechanisms underpinning monsoon development and dynamics. Here we circumvent the use of such single climate parameter metrics in favor of detecting directly the distinctive attributes of different monsoon regimes encoded in leaf fossils. Leaf form adapts to the prevailing climate, particularly under the extreme seasonal stresses imposed by monsoons, so it is likely that fossil leaves carry a unique signature of past monsoon regimes. Leaf form trait spectra obtained from fossils from Eocene basins in southern China were compared with those seen in modern leaves growing under known climate regimes. The fossil leaf trait spectra, including those derived from previously published fossil floras from northwestern India, were most similar to those found in vegetation exposed to the modern Indonesia-Australia Monsoon (I-AM), which is largely a product of seasonal migrations of the ITCZ. The presence of this distinctive leaf physiognomic signature suggests that although a monsoon climate existed in Eocene time across southern Asia the characteristics of the modern topographically-enhanced South Asia Monsoon had yet to develop. By the Eocene leaves in South Asia had become well adapted to an I-AM type regime across many taxa and points to the existence of a pervasive monsoon climate prior to the Eocene. No fossil trait spectra typical of exposure to the modern East Asia monsoon were seen, suggesting the effects of this system in southern

  11. Impacts of traditional architecture on the use of wood as an element of facade covering in Serbian contemporary architecture

    Directory of Open Access Journals (Sweden)

    Ivanović-Šekularac Jelena

    2011-01-01

    Full Text Available The world trend of re-use of wood and wood products as materials for construction and covering of architectural structures is present not only because of the need to meet the aesthetic, artistic and formal requirements or to seek inspiration in the return to the tradition and nature, but also because of its ecological, economic and energetic feasibility. Furthermore, the use of wood fits into contemporary trends of sustainable development and application of modern technical and technological solutions in the production of materials, in order to maintain a connection to nature, environment and tradition. In this study the author focuses on wood and wood products as an element of facade covering on buildings in our country, in order to extend knowledge about possibilities and limitations of their use and create a base for their greater and correct application. The subject of this research is to examine the application of wood and wood products as an element covering the exterior in combination with other materials applied in our traditional and contemporary homes with the emphasis on functional, representational art and the various possibilities of wood. In this study all the factors that affect the application of wood and wood products have been analyzed and the conclusions have been drawn about the manner of their implementation and the types of wood and wood products protection. The development of modern technological solutions in wood processing led to the production of composite materials based on wood that are highly resistant, stable and much longer lasting than wood. Those materials have maintained in an aesthetic sense all the characteristics of wood that make it unique and inimitable. This is why modern facade coating based on wood should be applied as a facade covering in the exterior of modern architectural buildings in Serbia, and the use wood reduced to a minimum.

    Tiwary, Ekta; Gupta, Rani

    2010-12-01

    A feather degrading strain of Bacillus licheniformis ER-15 was isolated which also degraded α-keratin of hooves. A detailed analysis revealed that a novel monomeric γ-glutamyl transpeptidase (GGT(30)), a proteolytic product of heterodimeric 67 kDa γ-glutamyl transpeptidase (GGT(67)), assists subtilisin during its action on α keratin. An equimolar combination of subtilisin and GGT(30) was designated as KerN and was used as ungual enhancer for topical application. KerN was effective in releasing proteins from nail plate surface and 300 µg of enzyme could release 41 µg protein/mg of nail after 24 h treatment. Scanning electron micrograph (SEM) revealed loosening of nail matrix confirming the action of KerN on nail keratin. Drug permeation studies revealed permeation of clotrimazole through both enzymatically pretreated nail plates and also through nail plates in presence of KerN. Nearly 58% drug could be retained by nail plates after 24 h of 300 µg/mL KerN which further enhanced up to 97% by prolonging the enzyme application. The enzyme was found to be stable in presence of drug even after 72 h. Thus, KerN can be used as an additive in formulation of topical drug for onchomycosis. PMID:20572051

    2010-12-01

    Full Text Available This study examines the effectiveness of handbook preparation as a method in the self-directed learning process of student teachers in teaching endocrine glands, and increasing their levels of knowledge. Thirty student teachers were selected from a biology department. A pencil and paper test and a clinical interview procedure were used to collect data. The test had two open-ended questions investigating the knowledge level of the sample about endocrine glands and the basic concepts of the subject. The interview was conducted to search the effectiveness of the handbook preparation process on self-directed learning of the student teachers. The results revealed that the student teachers had very limited knowledge and also had misconceptions related to the endocrine topic. The handbook preparation method was very helpful for the student teachers to overcome their misconceptions about the subject and to increase their knowledge level. It was suggested that handbook preparation may be helpful for teaching other biology topics as a self-directed learning tool. However, it should be considered that the student teachers had heterogeneity with respect to skills.

    The best strategy in the development of topical drug delivery systems may be to facilitate the permeation of drugs without any harmful effects, while staying on the skin surface and maintaining stability of the system. Nanodiamonds (NDs) play a key role with their excellent physicochemical properties, including high biocompatibility, physical adsorption, reactive oxygen species (ROS) scavenging capability, and photostabilizing activity. Z-average sizes of carboxylated ND (ND–COOH) agglutinate decreased significantly as the pH increased. Fluorescein-conjugated ND was observed only on the stratum corneum, and no sample diffused into the dermal layer even after 48 hours. Moreover, ND–COOH and ND–COOH/eugenol complex did not show significant toxic effects on murine macrophage cells. ND improved in vitro skin permeation >50% acting as a “drug reservoir” to maintain a high drug concentration in the donor chamber, which was supported by quartz crystal microbalance results. Moreover, ND–COOH could adsorb a drug amount equivalent to 80% of its own weight. A photostability study showed that ND–COOH increased the photostability ~47% with regard to rate constant of the eugenol itself. A significant decrease in ROS was observed in the ND–COOH and ND–COOH/eugenol complex compared with the negative control during intracellular ROS assay. Moreover, ROS and cupric reducing antioxidant capacity evaluation showed that ND–COOH had synergistic effects of antioxidation with eugenol. Therefore, ND–COOH could be used as an excellent topical drug delivery system with improved permeability, higher stability, and minimized safety issue. PMID:27307736

  3. Genetic architecture of flowering time as identified by induced mutations

    International Nuclear Information System (INIS)

    The different studies made to elucidate the genetic system controlling flowering time by means of induced mutations, mainly in Arabidopsis and barley and partly in other plants, are reviewed. It is intended to throw some light on the organization and relationships of the array of gene loci controlling this economically important character. Two hypotheses are proposed. The first is that single plant selections in M2 and onwards generally lead to single gene mutant lines. Single plant selections carrying two mutant genes affecting the same character are relatively rare. Those carrying polygenic mutations are extremely rare. The second hypothesis is that flowering time mutants of different origin are thought to carry mutations at different loci. Analyses of induced changes in flowering time by means of biometrical as well as classical Mendelian methods are compared with respect to the magnitude and direction of individual gene effect, linkage relationships, gene interactions (allelic and non-allelic) and heterosis phenomena. It is concluded that most studies support the proposed hypotheses. Allelism between mutated genes at different loci seems very rare, and the loci controlling flowering time are not evenly distributed all over the genome, but rather cluster in a few linkage groups. Epistatic interactions between flowering time mutant genes seem relatively rare. The effects of the different loci are mostly additive. Heterosis between single gene mutants generally results from complementation between wild-type dominant alleles of the mutated loci. This directly supports the dominance theory of heterosis. Biometrical analysis of induced changes in flowering time generally leads to rough conclusions, mostly similar to those predicted from natural variation. (author)

  7. Hybrid architecture for shallow accumulation mode AlGaAs/GaAs heterostructures with epitaxial gates

    International Nuclear Information System (INIS)

    Accumulation mode devices with epitaxially grown gates have excellent electrical stability due to the absence of dopant impurities and surface states. We overcome typical fabrication issues associated with epitaxially gated structures (e.g., gate leakage and high contact resistance) by using separate gates to control the electron densities in the Ohmic and Hall bar regions. This hybrid gate architecture opens up a way to make ultrastable nanoscale devices where the separation between the surface gates and the 2D electron gas is small. In this work, we demonstrate that the hybrid devices made from the same wafer have reproducible electrical characteristics, with identical mobility and density traces over a large range of 2D densities. In addition, thermal cycling does not influence the measured electrical characteristics. As a demonstration of concept, we have fabricated a hybrid single-electron transistor on a shallow (50 nm) AlGaAs/GaAs heterostructure that shows clear Coulomb blockade oscillations in the low temperature conductance

    2014-01-01

    The treatment of chronic inflammatory skin disease is associated with the use of topical corticosteroids. Their efficacy, tolerability and adverse effects depend on several factors, specifically potency, type of preparation, extemporaneous dilutions, quantity used, magnitude of the treated body surface, frequency of application, location, patient age, method of application and condition of the skin barrier. We report on two men suffering from chronic inflammatory skin disease, who presented with fatigue and cushingoid appearance after prolonged self-application of potent corticosteroids. Impairment of the skin barrier due to their underlying skin disease, frequent self-application of topical steroids and repeated application of the entire body led to extensive absorption of these substances, eventually culminating in the suppression of the pituitary-hypothalamic-adrenal axis. In conclusion, topical corticosteroids are effective and well-established therapeutic modalities. However, inappropriate use of topical corticosteroids can cause side effects. PMID:24751677

    2014-08-01

    Full Text Available The World Wide Web is the largest information repository available today. However, this information is very volatile and Web archiving is essential to preserve it for the future. Existing approaches to Web archiving are based on simple definitions of the scope of Web pages to crawl and are limited to basic interactions with Web servers. The aim of the ARCOMEM project is to overcome these limitations and to provide flexible, adaptive and intelligent content acquisition, relying on social media to create topical Web archives. In this article, we focus on ARCOMEM’s crawling architecture. We introduce the overall architecture and we describe its modules, such as the online analysis module, which computes a priority for the Web pages to be crawled, and the Application-Aware Helper which takes into account the type of Web sites and applications to extract structure from crawled content. We also describe a large-scale distributed crawler that has been developed, as well as the modifications we have implemented to adapt Heritrix, an open source crawler, to the needs of the project. Our experimental results from real crawls show that ARCOMEM’s crawling architecture is effective in acquiring focused information about a topic and leveraging the information from social media.

    Full Text Available Islamic architecture, a young field with a conservative scholarly lineage, has only recently begun to find its own theoretical bearings. After briefly reviewing the origins and formative stages of the field in the West, this article identifies a turning point brought about by the publication of Edward Saïd's seminal book Orientalism in 1978. It then introduces three critical notions, dynamic periodization, multiculturalism, and dialogue, which offer a framework for the study of Islamic architecture as a tradition with a solid historical selfconsciousness.

  7. The possibility of use of Kremicj granitoid (Serbia) as an architectural stone

    International Nuclear Information System (INIS)

    The stone from the granitoid pluton of Kremić in southern Serbia has been examined in order to evaluate the possibility of its use as an architectural stone. Both field observations and laboratory testing of specimens have been performed. Although the specimens were collected from the field surface level, their physicomechanical lab test results have shown that the rock mass itself fulfils all the requirements for use as an architectural stone set by the State through Serbian standards. Also, the stone quality is higher in deeper ground levels, where the weathering agents have less intense effects. This stone does not have high ornamental properties, but it has a finegrained texture and low mica content which has a positive effect on its technical characteristics and susceptibility to processing.

  14. Electrospun nanofiber meshes with tailored architectures and patterns as potential tissue-engineering scaffolds

    International Nuclear Information System (INIS)

    Using a stainless steel mesh as a template collector, electrospun nanofiber meshes with well-tailored architectures and patterns were successfully prepared from biodegradable poly (ε-caprolactone) (PCL). It was found that the resulting PCL nanofiber (NF) meshes had similar topological structures to that of the template stainless steel mesh. Such PCL nanofiber meshes (NF meshes) had improved the tensile strength with Young's modulus of 62.7 ± 5.3 MPa, which is >40% higher than the modulus of 44 ± 5.7 MPa as measured with the corresponding randomly oriented PCL nanofiber mats (RNF mat). On the other hand, the ultimate strain (87.30%) of the PCL NF meshes was distinctly lower than that of the PCL RNF mats (146.46%). To the best of our knowledge, this is the first time that the mechanical properties of nanofiber meshes with tailored architectures and patterns were studied and reported. When cultured with a mouse osteoblastic cell line (MC3T3-E1), the electrospun PCL NF meshes gave a much higher proliferation rate as compared with the randomly oriented PCL RNF mats. More importantly, it was found that the cells grew and elongated along the fiber orientation directions, and the resulted cellular organization and distribution mimicked the topological structures of the PCL NF meshes. These results indicated that the electrospun nanofiber scaffolds with tailored architectures and patterns hold potential for engineering functional tissues or organs, where an ordered cellular organization is essential

    Full Text Available This article responds to the misconceptions that continue to characterize the delivery of knowledge content in architectural courses. Based on reviewing the literature on pedagogy the paper explores the value and benefits of introducing evaluation research as a mechanism for critical inquiry and knowledge construction in theory courses in architecture and urbanism. A framework is developed and employed to demonstrate the way in which this type of learning can be incorporated.   The development and implementation of a series of in-class and off campus exercises in two different contexts reveal that structured actions and experiences help students to be in control over their learning while invigorating their understanding of the body of knowledge delivered in a typical lecture format. It firmly believed that this would offer students multiple learning opportunities while fostering their capabilities to shift from passive listeners to active learners and from knowledge consumers to knowledge producers.

  20. Characterization of individual barium titanate nanorods and their assessment as building blocks of new circuit architectures

    International Nuclear Information System (INIS)

    In this work, we report on the integration of individual BaTiO3 nanorods into simple circuit architectures. Polycrystalline BaTiO3 nanorods were synthesized by electrophoretic deposition (EPD) of barium titanate sol into aluminium oxide (AAO) templates and subsequent annealing. Transmission electron microscopy (TEM) observations revealed the presence of slabs of hexagonal polymorphs intergrown within cubic grains, resulting from the local reducing atmosphere during the thermal treatment. Electrical measurements performed on individual BaTiO3 nanorods revealed resistivity values between 10 and 100 Ω cm, which is in good agreement with typical values reported in the past for oxygen-deficient barium titanate films. Consequently the presence of oxygen vacancies in their structure was indirectly validated. Some of these nanorods were tested as proof-of-concept humidity sensors. They showed reproducible responses towards different moisture concentrations, demonstrating that individual BaTiO3 nanorods may be integrated in complex circuit architectures with functional capacities.

    The Cellular Access Digital Network (CADN) is the access vehicle through which cellular technology is brought into the mainstream of the evolving integrated telecommunications network. Beyond the integrated end-to-end digital access and per call network services provisioning of the Integrated Services Digital Network (ISDN), the CADN engenders the added capability of mobility freedom via wireless access. One key element of the CADN network architecture is the standard user to network interface that is independent of RF transmission technology. Since the Mobile Satellite System (MSS) is envisioned to not only complement but also enhance the capabilities of the terrestrial cellular telecommunications network, compatibility and interoperability between terrestrial cellular and mobile satellite systems are vitally important to provide an integrated moving telecommunications network of the future. From a network standpoint, there exist very strong commonalities between the terrestrial cellular system and the mobile satellite system. Therefore, the MSS architecture should be designed as an integral part of the CADN. This paper describes the concept of the CADN, the functional architecture of the MSS, and the user-network interface signaling protocols.

    Garcinia gardneriana is popularly used in skin disorders; therefore, this article investigated the effect of G. gardneriana extracts from leaves, bark and seeds and two isolated compounds in ear oedema and leucocytes migration caused by croton oil. The topical application of the extract of G. gardneriana leaves was able to reduce (70 ± 3%, and ID(50) 0.33 mg/ear) ear oedema, while the seeds (51 ± 5%) and the wood (60 ± 12%) extracts were less effective. In a time-course evaluation, the leaf extract (1 mg/ear) was effective when applied 2 hr before and until 3 hr after the stimulation, presenting a higher effectiveness when applied right after croton oil (83 ± 7% inhibition). In addition, the leaf extract was able to diminish the myeloperoxidase (MPO) activity in 64 ± 13%, which suggests the inhibition of leucocyte infiltration that was confirmed by histological analysis. Also, both biflavonoids isolated from the leaves of G. gardneriana, fukugetin (or morelloflavone) and 13-naringenin-II 8-eriodictyol (GB-2a), were able to reduce ear oedema, with ID(50) values of 0.18 (0.10-0.28) and 0.22 (0.15-0.31) mg/ear, respectively, besides the inhibition of MPO activity of 52 ± 6% and 64 ± 5%, respectively. Using the fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate, the leaf extract, fukugetin and GB-2a topically applied to the ear treated with croton oil reduced 52 ± 15%, 63 ± 17% and 83 ± 4%, respectively, the production of reactive oxygen species of the skin. Thus, these results reveal the anti-inflammatory effect of G. gardneriana leaves for topical usage, and both biflavonoids are responsible for this effect. PMID:21362142

  9. Severe hyperkalemia as a complication of timolol, a topically applied beta-adrenergic antagonist

    International Nuclear Information System (INIS)

    Severe hyperkalemia occurred in a patient with radiation pneumonitis and glaucoma shortly after beginning prednisone therapy. There was no evidence of renal failure, diabetes, acidosis, increased potassium intake, or significant tissue trauma. Medications having adverse effects on potassium metabolism were considered, and the patient's use of timolol maleate eyedrops was discontinued. His serum potassium level normalized despite continuation of the prednisone therapy. He became hyperkalemic on rechallenge with timolol and normokalemic following its withdrawal. This case indicates that the potential for beta-blocker-induced hyperkalemia exists even with topical appreciation

  11. The Concept of the Interculture in Time: (Intercultural Topics in Textbooks of French as a Foreign Language

    Directory of Open Access Journals (Sweden)

    Meta Lah

    2012-12-01

    Full Text Available The article deals with the concept of interculturality as used in foreign language didactics. In accordance with the definition of interculturality given in the first part of the article, two categories are included in the analysis – two “levels” of culture, each of them bearing a different name in literature, namely high and popular culture. Various textbooks used for teaching French as a foreign language in Slovenia in both the past and present were chosen for the analysis of topics that cover a fairly long period of time – among them the textbooks by two Slovenian authors: Južnič (1938 and Grad (1954, as well as some generally-used French textbooks, such as Cours de langue et de civilisation françaises (1953, Le nouveau sans frontières (1988 and Nouveau rond point (2011. The article is based on the hypothesis that high culture is more likely to be present in the older textbooks, which are based on traditional methods, whereas in modern textbooks more popular, everyday topics can be found. It is also presumed that topics in modern textbooks are, compared to their more traditional counterparts, introduced in an intercultural manner which could encourage students to compare the culture of the foreign country with their own. Both hypotheses are partly confirmed. In Slovenian textbooks there are very few culture-based topics. On the other hand, they are present in all French textbooks, regardless of the methodology. It is true that Mauger introduces more high culture than the others and that the intercultural topics are presented only in the most recent textbook. In all the others, it is exclusively the culture of the target country that is introduced.

    Twenty-four consecutive patients scheduled for fiberbronchoscopy were randomized to receive double-blind either intravenous (1.5 mg/kg) or laryngotracheal (3 mg/kg) lidocaine to evaluate the influence on post-bronchoscopic laryngospasm, pain in the throat and coughing. Plasma lidocaine concentrations were analyzed 5, 15, 30 and 60 min after administration. None of the patients demonstrated laryngospasm or pain in the throat during the first hour after bronchoscopy. Patients receiving topical lidocaine coughed significantly more than patients receiving intravenous lidocaine, with a median number of coughs of 20 compared to 4, during the first hour (P less than 0.01). The plasma lidocaine concentrations were significantly higher after intravenous than after topical administration (P less than 0.001). After intravenous administration the plasma lidocaine concentrations exceeded the accepted level for potential toxicity in five out of 11 patients, but none of the patients developed toxic symptoms and no side-effects were observed.

    2014-06-01

    Full Text Available 31 years old male suffered from a rare skin disorder, diagnosed of red skin syndrome. Seven years ago, symptoms was begun with a light itching on skin area of body as well as face, and visited a general practitioner, diagnosed of light allergic rhinitis. He was prescribed oral corticosteroid, methyl prednisolone 4 mg b.i.d and very potent topical corticosteroid, clobetasol. The symptoms was significantly disappeared and being rebound after stopping the prescription. To maintain this rebound effect, for seven years in on-off unhealed conditions, he used topical cream corticosteroid, clobetasol, that fully masked this worst rebound condition. When application of the topical cream was stopped, rebound effect relapsed and even red skin syndrome became worse than before. After 20 months of being fully stopped from corticosteroid, the symptoms finally slowly reduced. He almost fully recovered and had a normal life until now December 2013. By this case, we can learn that this red skin syndrome, resulted from side effect of corticosteroid, will be stopped by fully stopping administering orally or topically, and this will take quite long time for skin to recover.

  2. Kinetic Digitally-Driven Architectural Structures as ‘Marginal’ Objects – a Conceptual Framework

    Directory of Open Access Journals (Sweden)

    Sokratis Yiannoudes

    2014-07-01

    Full Text Available Although the most important reasons for designing digitally-driven kinetic architectural structures seem to be practical ones, namely functional flexibility and adaptation to changing conditions and needs, this paper argues that there is possibly an additional socio-cultural aspect driving their design and construction. Through this argument, the paper attempts to debate their status and question their concepts and practices.Looking at the design explorations and discourses of real or visionary technologically-augmented architecture since the 1960s, one cannot fail to notice the use of biological metaphors and concepts to describe them – an attempt to ‘naturalise’ them which culminates today in the conception of kinetic structures and intelligent environments as literally ‘alive’. Examining these attitudes in contemporary examples, the paper demonstrates that digitally-driven kinetic structures can be conceived as artificial ‘living’ machines that undermine the boundary between the natural and the artificial. It argues that by ‘humanising’ these structures, attributing biological characteristics such as self-initiated motion, intelligence and reactivity, their designers are ‘trying’ to subvert and blur the human-machine (-architecture discontinuity.The argument is developed by building a conceptual framework which is based on evidence from the social studies of science and technology, in particular their critique in modern nature-culture and human-machine distinctions, as well as the history and theory of artificial life which discuss the cultural significance and sociology of ‘living’ objects. In particular, the paper looks into the techno-scientific discourses and practices which, since the 18th century, have been exploring the creation of ‘marginal’ objects, i.e. seemingly alive objects made to challenge the nature-artifice boundary.

    The present survey determined women's participation in eight journals concerned with mental retardation and related topics. The number of female authors was recorded for all articles published in these journals from 1991 through 2000. The number of women on the editorial board each year, for each journal, also was tabulated. For all years and all journals, women were first authors of 41% of articles published. Women wrote 34% of single-author articles. Overall, 45% of all authors were women. Women constituted 34% of the editorial board members for the eight journals combined. In sum, these data suggest that women's contribution to the mental retardation literature decreases with the prestige of the activity. PMID:12597719

    Chang, Huai-Chien; Anilir, Serkan

    Currently, International Space Station (ISS) is capable to support 3 to 4 astronauts onboard for at least 6 months using an integrated life support system to support the need of crew onboard. Waste from daily life of the crew members are collected by waste recycle systems, electricity consumption depends on collecting solar energy, etc. though it likes the infrastructure we use on Earth, ISS can be comprehended nearly a self-reliant integrated architecture so far, this could be given an important hint for current architecture which is based on urban centralized infrastructure to support our daily lives but could be vulnerable in case of nature disasters. Comparatively, more and more economic activities and communications rely on the enormous urban central infrastructure to support our daily lives. Therefore, when in case of natural disasters, it may cut-out the infrastructure system temporarily or permanent. In order to solve this problem, we propose to design a temporary shelter, which is capable to work without depending on any existing infrastructure. We propose to use some closed-life-cycle or integrated technologies inspired by the possibilities of space and other emerging technologies into current daily architecture by using Infra-free® design framework; which proposes to integrate various life supporting infrastructural elements into one-closed system. We try to work on a scenario for post-disaster management housing as the method for solving the lifeline problems such as solid and liquid waste, energy, and water and hygiene solution into one system. And trying to establish an Infra-free® model of shelter for disaster area. The ultimate objective is to design a Temp Infra-free® model dealing with the sanitation and environment preservation concerns for disaster area.

    Zinc salt solutions administered as topical microbicides provided significant protection against herpes simplex virus type 2 infection in a mouse vaginal challenge model. However, at the therapeutic concentration, the salt solutions caused sloughing of sheets of vaginal epithelial cells. These observations limit the utility of zinc salts as microbicides and suggest that the application of zinc solutions to mucosal surfaces has the potential to cause damage that might increase susceptibility to secondary infections at a later time.

    2010-01-01

    The evolution of games as an alternative to traditional simulations in the military context has been gathering momentum over the past five years, even though the exploration of their use in the serious sense has been ongoing since the mid-nineties. Much of the focus has been on the aesthetics of the visuals provided by the core game engine as well as the artistry provided by talented development teams to produce not only breathtaking artwork, but highly immersive game play. Consideration of game technology is now so much a part of the modeling and simulation landscape that it is becoming difficult to distinguish traditional simulation solutions from game-based approaches. But games have yet to provide the much needed interactive free play that has been the domain of semi-autonomous forces (SAF). The component-based middleware architecture that game engines provide promises a great deal in terms of options for the integration of agent solutions to support the development of non-player characters that engage the human player without the deterministic nature of scripted behaviors. However, there are a number of hard-learned lessons on the modeling and simulation side of the equation that game developers have yet to learn, such as: correlation of heterogeneous systems, scalability of both terrain and numbers of non-player entities, and the bi-directional nature of simulation to game interaction provided by Distributed Interactive Simulation (DIS) and High Level Architecture (HLA).

  15. Effect of a topical glucocorticoid, budesonide, on nasal mucosal blood flow as measured with 133Xe wash-out technique

    International Nuclear Information System (INIS)

    The ''vasoconstrictor'' effect of dermally applicated steroids is a widely used parameter when determining the potency of glucocorticoids. A similar effect on the nasal mucosa has been suggested as providing an explanation for the clinical effect of topically administered glucocorticoids in the treatment of nasal disorders such as allergic and vasomotor rhinitis. The recently described 133Xe wash-out method was used for the purpose of blood flow determination in 11 healthy subjects. In a randomized double-blind cross-over study, the effect of topically administered budesonide, a non-halogenated glucocorticoid, for 1 week was compared with that of placebo. No difference was found to occur in the mucosal blood flow after the administration of budesonide, as compared with placebo. It seems likely that a more complex activity than vasoconstriction is responsible for the clinical effect in the treatment of nasal disorders, and further research is required in order to clarify this issue.

    German architect Gottfried Semper developed a theory on the “four elements of Architecture” tracing the origin of architecture back to the rise of the early human settlement and the creation of fire. With the notion ‘hearth’ as the first motive in architecture and the definition of three enclosing...... motives; mounding, enclosure and roof, Semper linked the cultural and social values of the primordial fireplace with the order and shape of architecture. He claimed that any building ever made was nothing but a variation of the first primitive shelters erected around the fireplace, and that the three...... enclosing motives existed only as defenders of the “sacred flame”. In that way Semper developed the idea that any architectural scenery can be described, analyzed and explained by understanding the contextual, symbolic and social values of how the four basic motives of hearth, mounding, enclosure, and roof...

    Full Text Available Personal financial investments are, as a matter of course, a topic of economic education because they are a life situation which is inherently economical. In contrast, faulty advising in banks which has become focussed upon due to the extent it has played a part in the recent financial crisis is mentioned neither in curricula nor in educational text books. Numerous private funds have been exposed as unprofitable investments. One reason for this problem is to be found in the marketing staff of the banks who did not invest their customer’s funds securely enough – and the customers did not notice it. What conclusions can be drawn from this for general financial education after the financial crisis? The economic education has failed to address the topic of “faulty advising in banks” as well. On the basis of categorical economic didactics the following contribution will analyse whether one has an exemplary case here upon which students can win generalized, transferable insights. In this context, the topic of personal financial investments will be classified in an efficient manner and the risk of opportunism in advising situations will be analysed with the help of the positive principal-agent theory. The results of this analysis of informational asymmetries within financial markets give direction to the development and revision of curricula in the didactics of economic education. With the following article a sustainable theoretical fundament will be created to underscore the obligatory inclusion of this topic in curricula as well as its realisation for target groups in school text books.

    The objective of this study was to evaluate the effectiveness of topical lavender-thymol in promoting episiotomy healing. This placebo-controlled, single-blinded, randomised clinical trial involved 60 primiparous women. REEDA score was used to evaluate the outcome of the trial. On the 7th post-partum day, women in Placebo-treated group had worse Redness, Edema, Ecchymosis, Discharge and Approximation (REEDA) score of 3.93 ± 3.65 compared with those in Lavender-thymol-treated group (2.03 ± 1.7) with significant difference (P = 0.013). Visual analogue Scale (VAS) score for pain at episiotomy in Lavender-thymol-treated group was 3.5 ± 1.9, whereas in Placebo-treated group it was 2.1 ± 2.2 (p = 0.011) for dyschezia, 3.8 ± 1.7 and 2.8 ± 1.6 in Placebo- and Lavender-thymol-treated women, respectively (p = 0.023). At 7th post-partum week, dyspareunia was more severe in Placebo-treated group compared with that in Lavender-thymol-treated group (5.3 ± 2.7 vs 2.7 ± 1.5 and p aromatherapy using lavender-thymol was highly effective, suitable and safe for episiotomy wound care with little or no expected side effects compared with that using placebo.

Pupillary size decreased slightly with timolol (0.1 mm, p = 0.03) and dorzolamide (0.2 mm, p < 0.001), but not with latanoprost. Timolol also reduced the maximal contraction amplitude significantly during red light (p = 0.02). Intraocular pressure was significantly...... reduced by all three drugs after 3.5 h (p < 0.01), while it remained unchanged during the control day (p = 0.3). CONCLUSION: Anti-glaucoma medications did not interfere with the blue light elicited PIPR. Dorzolamide reduced pupil size, while timolol reduced both pupil size and maximal contraction to red...

  4. ROMAN SPECTACLES BUILDINGS AS A SETTING FOR MARTYRDOM AND ITS CONSEQUENCES IN THE CHRISTIAN ARCHITECTURE

    Directory of Open Access Journals (Sweden)

    Jordina Sales Carbonell

    2014-10-01

    Full Text Available In the framework of the study of Christian buildings in the ruins of amphitheaters, theaters, stadiums and Roman circuses, becomes appropriate to develop some reflections mainly aimed helping to explain the symbolic dimension acquired by the ludic background in which a far from negligible part of the Christian martyrdoms took place, as outlined on the preserved sources. Although this ludic substrate is not the only factor to be considered, it’s the one that allowed the hagiographers composing stories —some with more historical veracity than others— with architectural settings charged with symbolism, where the victory of the martyrs as “athletes of Christ” was equated to the victory in secular games. All this greatly contributes to explain the subsequent relationship between Christian building and playful architecture occurred from the late fourth and early fifth century, and detected in the late antique and early medieval topography of some Roman cities. However, this issue has gone relatively unnoticed for Archeology, and when the two key elements —building and church— appear, with few exceptions, they are considered separately in case of being subjected to some kind of study.

    Full Text Available In the context of increased maintenance operations and generational renewal work, a nuclear owner and operator, like Electricité de France (EDF, is invested in the scaling-up of tools and methods of “as-built virtual reality” for whole buildings and large audiences. In this paper, we first present the state of the art of scanning tools and methods used to represent a very complex architecture. Then, we propose a methodology and assess it in a large experiment carried out on the most complex building of a 1300-megawatt power plant, an 11-floor reactor building. We also present several developments that made possible the acquisition, processing and georeferencing of multiple data sources (1000+ 3D laser scans and RGB panoramic, total-station surveying, 2D floor plans and the 3D reconstruction of CAD as-built models. In addition, we introduce new concepts for user interaction with complex architecture, elaborated during the development of an application that allows a painless exploration of the whole dataset by professionals, unfamiliar with such data types. Finally, we discuss the main feedback items from this large experiment, the remaining issues for the generalization of such large-scale surveys and the future technical and scientific challenges in the field of industrial “virtual reality”.

  6. Ethylene oxide's role as a reactive agent during sterilization: effects of polymer composition and device architecture.

    Sterilization conditions need to be optimized to effectively neutralize the bioburden while using short exposure times for minimizing the changes in chemical composition, material properties and device architecture. Towards this goal, effects of ethylene oxide (EtO) exposure parameters such as time, temperature, humidity, and EtO concentration on the polymer properties were investigated by monitoring the changes in composition, and the morphology of different types of structures in a family of poly(ethylene glycol) (PEG)-containing tyrosine-derived polycarbonates. EtO was found to esterify the carboxyl groups present in the desaminotyrosyl-tyrosine groups. Sterilization under conditions more severe than those normally used reduced the glass transition temperature (Tg) and the molecular weight of the polymers, and the presence of PEG in the polymer enhanced this effect. Furthermore, electron micrographs showed that EtO sterilization cycle conditions, even those considered "mild," were found to damage the fragile structures such as those found in electrospun mats and porous scaffolds. Our study shows that the presence of EtO-susceptible groups, fusible architecture, and surface morphology should be taken into account in choosing the appropriate EtO sterilization conditions.

  7. Exploiting parallelism in many-core architectures: Lattice Boltzmann models as a test case

    International Nuclear Information System (INIS)

    In this paper we address the problem of identifying and exploiting techniques that optimize the performance of large scale scientific codes on many-core processors. We consider as a test-bed a state-of-the-art Lattice Boltzmann (LB) model, that accurately reproduces the thermo-hydrodynamics of a 2D-fluid obeying the equations of state of a perfect gas. The regular structure of Lattice Boltzmann algorithms makes it relatively easy to identify a large degree of available parallelism; the challenge is that of mapping this parallelism onto processors whose architecture is becoming more and more complex, both in terms of an increasing number of independent cores and – within each core – of vector instructions on longer and longer data words. We take as an example the Intel Sandy Bridge micro-architecture, that supports AVX instructions operating on 256-bit vectors; we address the problem of efficiently implementing the key computational kernels of LB codes – streaming and collision – on this family of processors; we introduce several successive optimization steps and quantitatively assess the impact of each of them on performance. Our final result is a production-ready code already in use for large scale simulations of the Rayleigh-Taylor instability. We analyze both raw performance and scaling figures, and compare with GPU-based implementations of similar codes

    Lichen sclerosus (LS) is a chronic inflammatory skin condition usually located in the anogenital area. Topical corticosteroid therapy is the first choice treatment which may arrest or delay the progression of the disorder. We report the case of a 74-year-old man presented with a 6-month history of nodular lesions localized on penis. The man had a previous history of genital lesions that had been diagnosed as LS and treated with long-term topical corticosteroid therapy. After 3 months of corticosteroid therapy, the patient observed the appearance of several nodular erythematous lesions on the penis with progressive disappearance of the clinical symptoms of LS. These purple to red asymptomatic angiomatoid nodules resembled the clinical features of Kaposi sarcoma. PMID:19580581

    Sütterlin, Christa; Schiefenhövel, Wulf; Lehmann, Christian; Forster, Johanna; Apfelauer, Gerhard

    2014-01-01

    In recent years, the fine arts, architecture, music and literature have increasingly been examined from the vantage point of human ethology and evolutionary psychology. In 2011 the authors formed the research group 'Ethology of the Arts' concentrating on the evolution and biology of perception and behaviour. These novel approaches aim at a better understanding of the various facets represented by the arts by taking into focus possible phylogenetic adaptations, which have shaped the artistic capacities of our ancestors. Rather than culture specificity, which is stressed e.g. by cultural anthropology and numerous other disciplines, universal human tendencies to perceive, feel, think and behave are postulated. Artistic expressive behaviour is understood as an integral part of the human condition, whether expressed in ritual, visual, verbal or musical art. The Ethology of the Arts-group's research focuses on visual and verbal art, music and built environment/architecture and is designed to contribute to the incipient interdisciplinarity in the field of evolutionary art research.

    Full Text Available Home Based Enterprises (HBEs provide an enormous impact on the lives of the citizens and the environment. The impacts include: increase income and welfare of the family, provide job opportunities, improve the quality of homes and the environment, and ensure life sustainability. The existence of the business leads changes to the house. Those changes that made to the house are often ignore the comfort of home space and the environment as living space. This study aims to look at the development of HBEs performed by community in Kampoeng Pandean. The measurement items used are architectural sustainability factors, ie economical sustainability, social sustainability, and enviromental sustainability. The study is located in Kampoeng Pandean Sidoarjo. The method used is a combination of qualitative and quantitative method. The results show that HBEs in Kampoeng Pandean have not fully supported the sustainable architecture. Environmental sustainability has not been met, due to the density of the environment, the high percentage of building area to land area, and the construction of business space does not consider the comfort factor.

  12. Syntactic Topic Models

    CERN Document Server

    Boyd-Graber, Jordan

    2010-01-01

    The syntactic topic model (STM) is a Bayesian nonparametric model of language that discovers latent distributions of words (topics) that are both semantically and syntactically coherent. The STM models dependency parsed corpora where sentences are grouped into documents. It assumes that each word is drawn from a latent topic chosen by combining document-level features and the local syntactic context. Each document has a distribution over latent topics, as in topic models, which provides the semantic consistency. Each element in the dependency parse tree also has a distribution over the topics of its children, as in latent-state syntax models, which provides the syntactic consistency. These distributions are convolved so that the topic of each word is likely under both its document and syntactic context. We derive a fast posterior inference algorithm based on variational methods. We report qualitative and quantitative studies on both synthetic data and hand-parsed documents. We show that the STM is a more pred...

    2012-08-01

    This document is one in a series of topical reports compiled by the Pacific Northwest National Laboratory to summarize technical information on selected topics important to the performance of a probabilistic seismic hazard analysis (PSHA) of the Hanford Site. The purpose of this report is to summarize available data and analyses relevant to the Yakima Fold Belt (YFB) that may bear on the question of whether or not the YFB behaves as a single seismotectonic province in which activity along one fold structure is representative of behavior along all other fold structures. This topic has met with a fairly high level of contention in the expert community and has the potential to result in significant impacts on an evaluation of seismic hazard at the Hanford Site. This report defines the relevant alternative conceptual models relevant to this technical issue and the arguments and data that support those models. It provides a brief description of the technical issue and principal uncertainties; a general overview on the nature of the technical issue, along with alternative conceptual models, supporting arguments and information, and uncertainties; and finally, it suggests some possible approaches for reducing uncertainties regarding this issue.

    2011-07-01

    We propose novel correlator receiver architecture with a PnpN optical thyristor operating as optical hard-limiter, and demonstrate a multiple-access interference rejection of the proposed correlator receiver. The proposed correlator receiver is composed of the 1×2 splitter, optical delay line, 2×1 combiner, and fabricated PnpN optical thyristor. The proposed correlator receiver enhances the system performance because it excludes some combinations of multiple-access interference patterns from causing errors as in optical code-division multiple access systems with conventional optical receiver shown in all previous works. It is found that the proposed correlator receiver can fully reject the interference signals generated by decoding processing and multiple access for two simultaneous users.

    2012-01-01

    In a context of pesticide use reduction, alternatives to chemical-based crop protection strategies are needed to control diseases. Crop and plant architectures can be viewed as levers to control disease outbreaks by affecting microclimate within the canopy or pathogen transmission between plants. Modeling and simulation is a key approach to help analyze the behaviour of such systems where direct observations are difficult and tedious. Modeling permits the joining of concepts from ecophysiology and epidemiology to define structures and functions generic enough to describe a wide range of epidemiological dynamics. Additionally, this conception should minimize computing time by both limiting the complexity and setting an efficient software implementation. In this paper, our aim was to present a model that suited these constraints so it could first be used as a research and teaching tool to promote discussions about epidemic management in cropping systems. The system was modelled as a combination of individual hosts (population of plants or organs) and infectious agents (pathogens) whose contacts are restricted through a network of connections. The system dynamics were described at an individual scale. Additional attention was given to the identification of generic properties of host-pathogen systems to widen the model's applicability domain. Two specific pathosystems with contrasted crop architectures were considered: ascochyta blight on pea (homogeneously layered canopy) and potato late blight (lattice of individualized plants). The model behavior was assessed by simulation and sensitivity analysis and these results were discussed against the model ability to discriminate between the defined types of epidemics. Crop traits related to disease avoidance resulting in a low exposure, a slow dispersal or a de-synchronization of plant and pathogen cycles were shown to strongly impact the disease severity at the crop scale.

  12. Spotlight Topics

    Science.gov (United States)

    A Spotlight Topic consists of a set of two or more review articles focused on a specific subject in surface science. The topics are recommended by the Board of Editors. A topic may be chosen because it is particularly new or fast-breaking, thus deserving introduction to the general readership. Or, it may be because a topic is especially controversial or confusing, requiring clarification by experts. Each review will give a critical assessment rather than an encyclopedic report. While our editors always will insist on fairness and accuracy, any review which forwards an opinion is bound to be somewhat subjective. Therefore, it is the editors' wish that the set of reviews written by different authors on the same subject matter will provide a broad and balanced viewpoint. It is often the case that an author who is an expert in a technique or method may be especially enthusiastic or critical about this technique or method. A companion review in the set may provide a different viewpoint. We are hopeful that the reader, after studying these reviews and checking some of the key references, will obtain an informed opinion of the subject. We think the set of reviews in a spotlight area will considerably shorten the ``learning time'' that a nonexpert would otherwise need to become knowledgeable about a subject.

    With the aim of establishing the formulation of a new hydrophilic auto-gelling medical device for biomedical applications, fibroin-based microspheres were prepared. The proposed microspheres were produced by a cost-effective and industrially scalable technique, such as the spray-drying. Spray-dried silk fibroin microspheres were obtained and the effects of different hydrophilic polymer on the process yield, microsphere morphology and conformation transition of fibroin were evaluated. The final auto-gelling formulations were obtained by adding calcium gluconate (as a calcium source for alginate crosslinking) to the prepared microspheres and tested by an in vitro gelling test. This study showed that the combination of fibroin with sodium alginate and poloxamer produced the most promising auto-gelling formulation for specific biomedical applications, such as the treatment of pressure ulcers.

    Full Text Available In order to make an issue as complex and controversial as that of ‘national identity’ teachable in the advanced EFL-classroom, it has to be reduced to exemplary aspects and illustrated with concrete examples. Therefore, I will suggest an appropriate ‘Course Opener,’ briefly survey the historical unfolding of the American identity concept in order to provide teachers with the necessary background knowledge, and then suggest two teaching units, the first of which traces some major developments by means of ‘classic’ texts, whereas the second deals with the crucial issue of whether a shared language is a prerequisite for a shared identity.

  1. Modern nuclear medicine methods as a topic of biophysics in veterinary training at UVM in Kosice

    International Nuclear Information System (INIS)

    Diagnostic and therapeutic application of ionising radiation is very important in all of branches of medicine including veterinary medicine. In veterinary training at University of Veterinary Medicine in Kosice (UVM), biophysics is a basic subject and it grants physical basis necessary for understanding subsequent subjects such as veterinary surgery, roentgenology, orthopedics. In view of this, traditional methods of radiology such as fluoroscopy, skiagraphy and tomography are explaining. The appearance and application of the theory so called reconstruction of image and also computers led to qualitatively new solutions via the development of modern methods in radiology. Explaining of physical principles, advantages or disadvantages of these new methods is also important in veterinary training although some of them do not use in veterinary practice yet. Two modern methods of nuclear medicine using in diagnostic (SPECT and PET) are discussed bellow. (authors)

  2. Improved Materials for Use as Components in Kraft Black Liquor Recovery Boilers; TOPICAL

    International Nuclear Information System (INIS)

    This Cooperative Research and Development Agreement (CRADA) was undertaken to evaluate current and improved materials and materials processing conditions for use as components in kraft black liquor recovery boilers and other unit processes. The main areas addressed were: (1) Improved Black Liquor Nozzles, (2) Weld Overlay of Composite Floor Tubes, and (3) Materials for Lime Kilns. Iron aluminide was evaluated as an alternate material for the nozzles used to inject an aqueous solution known as black liquor into recovery boilers as well for the uncooled lining in the ports used for the nozzles. Although iron aluminide is known to have much better sulfidation resistance in gases than low alloy and stainless steels, it did not perform adequately in the environment where it came into contact with molten carbonate, sulfide and sulfate salts. Weld overlaying carbon steel tubes with a layer of stainless weld metal was a proposed method of extending the life of recovery boiler floor tubes that have experienced considerable fireside corrosion. After exposure under service conditions, sections of weld overlaid floor tubes were removed from a boiler floor and examined metallographically. Examination results indicated satisfactory performance of the tubes. Refractory-lined lime kilns are a critical component of the recovery process in kraft pulp mills, and the integrity of the lining is essential to the successful operation of the kiln. A modeling study was performed to determine the cause of, and possible solutions for, the repeated loss of the refractory lining from the cooled end of a particular kiln. The evaluation showed that the temperature, the brick shape and the coefficient of friction between the bricks were the most important parameters influencing the behavior of the refractory lining

The extract of R. ferruginea stem bark was incorporated into the oily phase of the nanoemulsion by the method of phase inversion at low energy. The developed nanoemulsion had an average droplet size of 47.88±8.20 nm and a polydispersibility index of 0.228. Uniformity of size, spherical shape of droplet, and absence of clusters were confirmed by transmission electronic microscopy. The zeta potential was -34.7±1.15 mV. The nanoemulsion showed a moderate degree of skin irritation in the agarose overlay assay in vitro. The content of the extract markers, myrsinoic acids A and B, was 54.10±0.08 and 53.03 µg/g in the formulation, respectively. The formulation demonstrated pseudoplastic and thixotropic rheological behavior. In vitro release of chemical markers was controlled by diffusion mechanism. An extract-loaded nanoemulsion showed a topical anti-inflammatory activity in a croton oil-induced edema ear model, with a decrease in tumor necrosis factor release and myeloperoxidase activity. The nanoemulsion was 160% more efficient than the conventional cream containing 0.13% of the extract. The nanoemulsion showed suitable properties as a carrier for topical use of R. ferruginea extract and the approach for improving the topical anti-inflammatory activity.

    The cutaneous penetration of hydrophobic active molecules is of foremost concern in the dermatology and cosmetic formulation fields. The poor solubility in water of those molecules limits their use in hydrophilic forms such as gels, which are favored by patients with chronic skin disease. The aim of this work is to design a novel nanocarrier of hydrophobic active molecules and to determine its potential as an ingredient of a topical form. The nanocarrier consists of an oily core surrounded by a protective shell of alginate, a natural polysaccharide isolated from brown algae. These calcium alginate-based nanocarriers (CaANCs) were prepared at room temperature and without the use of organic solvent by an accelerated nanoemulsification-polymer crosslinking method. The size (hydrodynamic diameter ˜200 nm) and surface charge (zeta potential ˜ - 30 mV) of the CaANCs are both compatible with their application on skin. CaANCs loaded with a fluorescent label were stable in model hydrophilic galenic forms under different storage conditions. Curcumin was encapsulated in CaANCs with an efficiency of ˜95%, fully retaining its antioxidant activity. The application of the curcumin-loaded CaANCs on excised human skin led to a significant accumulation of the active molecules in the upper layers of the skin, asserting the potential of these nanocarriers in active pharmaceutical and cosmetic ingredients topical delivery.

    Background information is documented on the mass cultivation of aquatic plants and systems design that is available from the literature and through consultation with active research scientists and engineers. The biology of microalgae, macroalgae, and aquatic angiosperms is discussed in terms of morphology, life history, mode of existence, and ecological significance, as they relate to cultivation. The requirements for growth of these plants, which are outlined in the test, suggest that productivity rates are dependent primarily on the availability of light and nutrients. It is concluded that the systems should be run with an excess of nutrients and with light as the limiting factor. A historical review of the mass cultivation of aquatic plants describes the techniques used in commercial large-scale operations throughout the world and recent small-scale research efforts. This review presents information on the biomass yields that have been attained to date in various geographical locations with different plant species and culture conditions, emphasizing the contrast between high yields in small-scale operations and lower yields in large-scale operations.

  13. Smugglers masters as lobbying. Off scanner at the borders is a topic for politicians

    International Nuclear Information System (INIS)

    Smugglers, who make use of the Ukraine-Slovak border for their business, might be satisfied after last week. The Slovak government ordered the switching off of scanning equipment monitoring the movement of goods by train through the Matovce border line. The modern equipment was substituted by people, who aren't able to check freight cars as effectively as gadgets. Not only in Ukraine are they celebrating this success in corruption, who demanded the shut-off of the scanning equipment The bosses on the Slovak side are also rubbing their hands. As told to TREND by Margareta Grecova, spokeswoman for Cargo Slovakia, 90% of goods that cross through the border at Matovce are unloaded. The most frequently transported commodities are ore, coal, chemical and petroleum products. Smugglers put their consignments among iron ore and coal. They prefer goods with high consumer taxes. Besides alcohol, there are mainly cigarettes. These are put into boxes which are concealed in various parts of the train. Favorite places are on the cars, approximately 15 centimeters underneath loaded ore and coal. Contraband may leave the train anywhere during a journey, most probably with Slovak help. A Ukrainian accomplice provides an alert where to find the smuggled cigarettes. A shadow of suspicion has fallen also on railway employees. If smuggled cigarettes are unloaded at train stations, along the track and at incidental stops, railway cooperation is highly probable. If nothing else they pretend not to see anything and ignore activities happening on a nearby train. This doesn't exclude the cooperation of employees in the firms where the cars unload. Or the customs officers, who receive alerts from Ukraine, and ignore certain parts of the train. It was the scanning devices which was helping to lessen corruption, each device making an archival recording of monitored cars. Moreover, it was proven that the devices could check trains incomparably better than people. Customs started using them for

    1997-01-01

    An information system architecture defines the components of a system and the interfaces among the components. A good architecture is essential for creating an Integrated Advanced Information Management System (IAIMS) that works as an integrated whole yet is flexible enough to accommodate many users and roles, multiple applications, changing vendors, evolving user needs, and advancing technology. Modularity and layering promote flexibility by reducing the complexity of a system and by restricting the ways in which components may interact. Enterprise-wide mediation promotes integration by providing message routing, support for standards, dictionary-based code translation, a centralized conceptual data schema, business rule implementation, and consistent access to databases. Several IAIMS sites have adopted a client-server architecture, and some have adopted a three-tiered approach, separating user interface functions, application logic, and repositories. PMID:9067884

    1982-02-01

    Recently there has been little interest in topical contraceptives. The most popular are the cervical cap and the diaphragm. Other types of mechanical contraceptive devices are being investigated. Standley and Kessler have developed a device for introduction into the cervical canal with a reservoir of spermatocide, it does not block the flow of blood during menstruation. New models of vaginal rings are also being developed which are simple enough for self-insertion and also contain a reservoir of spermatocide. Work is being done on spermatocide-containing sponges in many countries. Another project being investigated is the possibility of using natural proteins, collagens, and other substances which absorb spermatozoids. The ancients used various vaginal suppositories to kill spermatozoids; in the late 19th century quinine sulfate was used for this, and a variety of substances have been used recently. These spermicidal creams also have the advantage of acting as anti-infectious agents in many cases. But they do have some negative effects. They are about 85% effective, are local irritants, and some cause discomfort during intercourse. And it is possible that some are resorbed by the body and act on the liver and other organs. Vaginal globules and suppositories are also popular. The "Kontraceptin-T" brand contains quinosol, boric acid, and tannin. There are also foaming tablets which are mixed with water and then introduced. New locally-active chemical substances are being developed in Japan, West Germany, and the USSR. Kontraceptin-E contains paranonyl-phenoxypolyethylene glycol and sodium dioctylsulfosuccinate. The "Norforks" and other preparations contain mercurial compounds which may turn out to be harmful. The future promises the development of products which will act to prevent fertilization by acting on the hyaluronidase and the acrosine of the spermatozoid, thus preventing it from penetrating the ovum. It would be best to find enzyme inhibitors which are

    In this work, bicellar systems, bilayered disc-shaped nanoaggregates formed in water by phospholipids, are proposed as a novel strategy for delivery of the anti-inflammatory flufenamic acid (FFA) to the skin. A comparative percutaneous penetration study of this drug in bicellar systems and other vehicles was conducted. The effects induced on the skin by the application of FFA in the different vehicles were analyzed by attenuated total reflectance-fourier transform infrared (ATR-FTIR). Additionally, using the microscopic technique freeze-substitution transmission electron microscopy (FSTEM) and X-ray scattering technique using synchrotron radiation (SAXS-SR), we studied the possible microstructural and organizational changes that were induced in the stratum corneum (SC) lipids and the collagen of the skin by the application of FFA bicellar systems. Bicellar systems exhibited a retarder effect on the percutaneous absorption of FFA with respect to the other vehicles without promoting disruption in the SC barrier function of the skin. Given that skin disruption is one of the main effects caused by inflammation, prevention of disruption and repair of the skin microstructure should be prioritized in anti-inflammatory formulations.

  1. Development of backfill material as an engineered barrier in the waste package system. Interim topical report

    International Nuclear Information System (INIS)

    A backfill barrier, emplaced between the containerized waste and the host rock, can both protect the other engineered barriers and act as a primary barrier to the release of radionuclides from the waste package. Attributes that a backfill should provide in order to carry out its required function have been identified. Primary attributes are those that have a direct effect upon the release and transport of radionuclides from the waste package. Supportive attributes do not directly affect radionuclide release but are necessary to support the primary attributes. The primary attributes, in order of importance, are: minimize (retard or exclude) the migration of ground water between the host rock and the waste canister system; retard the migration of selected chemical species (corrosive species and radionuclides) in the ground water; control the Eh and pH of the ground water within the waste-package environment. The supportive attributes are: self-seal any cracks or discontinuities in the backfill or interfacing host geology; retain performance properties at all repository temperatures; retain peformance properties during and after receiving repository levels of gamma radiation; conduct heat from the canister system to the host geology; retain mechanical properties and provide resistance to applied mechanical forces; retain morphological stability and compatibility with structural barriers and with the host geology for required period of time. Screening and selection of candidate backfill materials has resulted in a preliminary list of materials for testing. Primary emphasis has been placed on sodium and calcium bentonites and zeolites used in conjunction with quartz sand or crushed host rock. Preliminary laboratory studies have concentrated on permeability, sorption, swelling pressure, and compaction properties of candidate backfill materials

    2013-01-01

    Multithreaded architectures now appear across the entire range of computing devices, from the highest-performing general purpose devices to low-end embedded processors. Multithreading enables a processor core to more effectively utilize its computational resources, as a stall in one thread need not cause execution resources to be idle. This enables the computer architect to maximize performance within area constraints, power constraints, or energy constraints. However, the architectural options for the processor designer or architect looking to implement multithreading are quite extensive and

    Ocular hypertension is a major risk factor for the development and progression of glaucoma. Frequent and long-term application of latanoprost often causes undesirable local side effects, which are a major cause of therapeutic failure due to loss of persistence in using this glaucoma medical therapy. In the present study, we developed a thermosensitive chitosan-based hydrogel as a topical eye drop formulation for the sustained release of latanoprost to control ocular hypertension. The developed formulation without preservatives may improve compliance and possibly even efficacy. The results of this study support its biocompatibility and sustained-release profile both in vitro and in vivo. After topical application of latanoprost-loaded hydrogel, triamcinolone acetonide-induced elevated intraocular pressure was significantly decreased within 7 days and remained at a normal level for the following 21 days in rabbit eyes. This newly developed chitosan-based hydrogel may provide a non-invasive alternative to traditional anti-glaucoma eye drops for glaucoma treatment. PMID:27083831

    The aim of this study is to investigate the antimicrobial efficacy of two different nanoemulsion (NE) formulations against Gram-positive and Gram-negative bacteria in an in vivo rodent scald burn model. Male Sprague-Dawley rats were anesthetized and received a partial-thickness scald burn. Eight hours after burn injury, the wound was inoculated with 1 × 10(8) colony-forming units of Pseudomonas aeruginosa or Staphylococcus aureus. Treatment groups consisted of two different NE formulations (NB-201 and NB-402), NE vehicle, or saline. Topical application of the treatment was performed at 16 and 24 hours after burn injury. Animals were killed 32 hours after burn injury, and skin samples were obtained for quantitative wound culture and determination of dermal inflammation markers. In a separate set of experiments, burn wound progression was measured histologically after 72 hours of treatment. Both NE formulations (NB-201 and NB-402) significantly reduced burn wound infections with either P. aeruginosa or S. aureus and decreased median bacterial counts at least three logs when compared with animals with saline applications (p wound as measured by myeloperoxidase (MPO) assay and histopathology (p wound progression 72 hours after injury. Topically applied NB-201 and NB-402 are effective in decreasing Gram-positive and Gram-negative bacteria growth in burn wounds, reducing inflammation, and abrogating burn wound progression.

    Full Text Available The financial crisis of 2008 ff. and financial crises in general should be a central topic of social science education because these crises are a recurrent and therefore structural feature of modern capitalism which has severe consequences for citizens’ quality of life. Hence, the citizenry should know how to prevent such developments which endanger its well-being in a massive way. Therefore, learners should understand the relationship between the quality of people’s everyday lives and those economic institutions and political decisions which have led to the current mess. They should be enabled to critically evaluate the current misregulation of the financial sector and the economy in order to identify possible policy measures to prevent or at least to mitigate future crises. By educating (young citizens in this way, the (future general public can – as a necessary counterweight to the lobbyism of the finance industry – exert more prudent political pressure which gives politicians a greater incentive to regulate the financial sector and the economy in a manner which is beneficial for the vast majority of the people instead of for a small elite. Two core concepts of the social sciences can be used to make the roots of the seemingly complex topic more understandable for learners: liability and inequality.

Ascorbic acid has potent antioxidant and anti-inflammatory properties preventing photodamage of keratinocytes; however, due to its instability and low skin penetration, an appropriate carrier is mandatory to obtain desirable efficacy. The present work investigates the ability of a specific ascorbate phosphatidylcholine (PC liposome to overcome the barrier of the stratum corneum and deliver the active agent into the dermis to prevent photodamage. Abdominal skin from ten patients was used. Penetration of PC liposomes was tested ex vivo in whole skin, epidermis, and dermis by means of fluorescein and sodium ascorbate. Histology and Franz diffusion cells were used to monitor the percutaneous absorption. Ultraviolet (UV-high performance liquid chromatography was used to analyze diffusion of sodium ascorbate through the different skin layers, while spectrofluorimetry and fluorescent microscopy were used for fluorescein monitoring. UVA/UVB irradiation of whole skin was applied to analyze the antioxidant capacity by Trolox assay and anti-inflammatory effects by tumor necrosis factor alpha and interleukin 1 beta enzyme-linked immunoassay. PC liposomal formulation improved skin penetration of fluorescein and ascorbate. Fluorescein PC liposomes showed better diffusion through epidermis than dermis while ascorbate liposomes showed better diffusion through the dermis than

    This study reports the preparation, characterization and testing of a sputtered Pd mesh-like anode as an advanced electrocatalyst for H2 production from alkaline ethanol solutions in an Alkaline Membrane Electrolyzer (AEM). Pd anodic catalyst is prepared by magnetron sputtering technique onto a microfiber carbon paper support. Scanning Electron Microscopy images reveal that the used preparation technique enables to cover the surface of the carbon microfibers exposed to the Pd target, leading to a continuous network that also maintains part of the original carbon paper macroporosity. Such novel anodic architecture (organic binder free) presents an excellent electro-chemical performance, with a maximum current density of 700 mA cm-2 at 1.3 V, and, concomitantly, a large H2 production rate with low energy requirement compared to water electrolysis. Potassium hydroxide emerges as the best electrolyte, whereas temperature exerts the expected promotional effect up to 90 °C. On the other hand, a 1 mol L-1 ethanol solution is enough to guarantee an efficient fuel supply without any mass transfer limitation. The proposed system also demonstrates to remain stable over 150 h of operation along five consecutives cycles, producing highly pure H2 (99.999%) at the cathode and potassium acetate as the main anodic product.

    The use of a novel cross-linked thiolated chitosan (CTS) was investigated as the main component of aqueous dispersions (at 1% and 3% w/v) for topical drug delivery systems. The nonionic theophiline (Th) and the cationic diltiazem(.)HCl (Dt) (at 0.5% w/v concentration) were used as model drugs. All aqueous dispersions behaved as viscoelastic fluids. The CTS 1% dispersions showed predominance of viscous component and low viscosity. However, in the CTS 3% dispersions, both the elastic component and high viscosities prevailed. So, texture parameters improved from CTS 1% to 3% dispersions and CTS 3%-Dt showed greater cohesion and adhesion than CTS 3%-Th, but always below CTS alone. All dispersions showed a Fickian diffusion mechanism. Despite release profiles of both drugs almost fully overlapped at 1% CTS, diffusion coefficients confirmed Dt released faster than Th at 3% CTS. The rheological behavior and the chemical nature of the drugs explained these results. PMID:27474615

  12. Heparin-binding peptide amphiphile supramolecular architectures as platforms for angiogenesis and drug delivery

    Science.gov (United States)

    Chow, Lesleyann W.

    A fascinating phenomenon in nature is the self-assembly of molecules into a functional, hierarchical structure. In the past decade, the Stupp Laboratory has developed several classes of self-assembling biomaterials, one of which is the synthetic peptide amphiphile (PA). Self-assembling PAs are attractive and versatile biomolecules that can be customized for specific applications in regenerative medicine. In particular, a heparin-binding peptide amphiphile (HBPA) containing a specific heparin-binding peptide sequence was used here to induce angiogenesis and serve as a delivery vehicle for growth factors and small hydrophobic molecules. Throughout this dissertation, the HBPA/heparin system is used in different architectures for a variety of regenerative medicine applications. In one aspect of this work, hybrid scaffolds made from HBPA/heparin gelled on a poly(L-lactic acid) (PLLA) fiber mesh were used to promote angiogenesis to facilitate pancreatic islet transplantation for the treatment of type 1 diabetes. Delivery of growth factors with HBPA/PLLA scafflolds increased vessel density in vivo and correlated with improved transplant outcomes in a streptozotocin-induced diabetic mouse model. Soluble HBPA nanofiber architectures were also useful for islet transplantation applications. These nanofibers were used at concentrations below gelation to deliver growth factors into the dense islet cell aggregate, promoting cell survival and angiogenesis in vitro. The nanostructures infiltrated the islets and promoted the retention of heparin and growth factors within the islet. Another interesting growth factor release system discussed here is the HBPA membrane structure. HBPA was found to self-assemble with hyaluronic acid, a large biopolymer found in the body, into macroscopic, hierarchically-ordered membranes. Heparin was incorporated into these membranes and affected the membrane's mechanical properties and growth factor release. Human mesenchymal stem cells were also shown

    Full Text Available Lengthy co-evolution of Homo sapiens and Mycobacterium tuberculosis, the main causative agent of tuberculosis, resulted in a dramatically successful pathogen species that presents considerable challenge for modern medicine. The continuous and ever increasing appearance of multi-drug resistant mycobacteria necessitates the identification of novel drug targets and drugs with new mechanisms of action. However, further insights are needed to establish automated protocols for target selection based on the available complete genome sequences. In the present study, we perform complete proteome level comparisons between M. tuberculosis, mycobacteria, other prokaryotes and available eukaryotes based on protein domains, local sequence similarities and protein disorder. We show that the enrichment of certain domains in the genome can indicate an important function specific to M. tuberculosis. We identified two families, termed pkn and PE/PPE that stand out in this respect. The common property of these two protein families is a complex domain organization that combines species-specific regions, commonly occurring domains and disordered segments. Besides highlighting promising novel drug target candidates in M. tuberculosis, the presented analysis can also be viewed as a general protocol to identify proteins involved in species-specific functions in a given organism. We conclude that target selection protocols should be extended to include proteins with complex domain architectures instead of focusing on sequentially unique and essential proteins only.

Aims: To study the efficacy and safety of oral terbinafine pulse as a monotherapy and in combination with topical ciclopirox olamine 8% or topical amorolfine hydrochloride 5% in onychomycosis. Methods: A clinical comparative study was undertaken on 96 Patients of onychomycosis during the period between August 2005 to July 2006. Forty-eight patients were randomly assigned in group A to receive oral terbinafine 250 mg, one tablet twice daily for seven days every month (pulse therapy; 24 patients in group B to receive oral terbinafine pulse therapy plus topical ciclopirox olamine 8% to be applied once daily at night on all affected nails; and 24 patients in group C to receive oral terbinafine pulse therapy plus topical amorolfine hydrochloride 5% to be applied once weekly at night on all the affected nails. The treatment was continued for four months. The patients were evaluated at four weekly intervals till sixteen weeks and then at 24 and 36 weeks. Results: We observed clinical cure in 71.73, 82.60 and 73.91% patients in groups A, B and C, respectively; Mycological cure rates against dematophytes were 88.9, 88.9 and 85.7 in groups A, B and C, respectively. The yeast mycological cure rates were 66.7, 100 and 50 in groups A, B and C, respectively. In the case of nondermatophytes, the overall response was poor: one out of two cases (50% responded in group A, while one case each in group B and group C did not respond at all. Conclusion: Terbinafine pulse therapy is effective and safe alternative in treatment of onychomycosis due to dermatophytes; and combination therapy with topical ciclopirox or amorolfine do not show any significant difference in efficacy in comparison to monotherapy with oral terbinafine.

    ENGLISH ABSTRACT: Enterprise Architecture (EA is a new discipline that has emerged from the need to create a holistic view of an enterprise, and thereby to discover business/IT integration and alignment opportunities across enterprise structures. Previous EA value propositions that merely focus on IT cost reductions will no longer convince management to invest in EA. Today, EA should enable business strategy in the organisation to create value. This resides in the ability to do enterprise optimisation through process standardisation and integration. In order to do this, a new approach is required to integrate EA into the strategy planning process of the organisation.
    This article explores the use of three key artefacts – operating models, core diagrams, and an operating maturity assessment as defined by Ross, Weill & Robertson [1] – as the basis of this new approach. Action research is applied to a research group to obtain qualitative feedback on the practicality of the artefacts.

    increased penetration depth compared to the non-irradiated skin (mode A: The ratio of the amount of the dye in the deeper (second 10% of the stratum corneum to the amount of the dye in the upper 10% of the stratum corneum showed medians and interquartile ranges for mode A of 0.017 (0.007/0.050, for mode B of 0.084 (0.021/0.106, for mode C of 0.104 (0.069/0.192 (difference between modes: p=0.0112, significant; comparison mode A with mode C: p<0.01, significant. In contrast to fluorescein, the lipophilic curcumin showed no differences in the penetration kinetics, in reference to whether the skin was irradiated with wIRA or not. These effects were confirmed by laser scanning microscopy. Water-filtered infrared-A irradiation increased the hydration of the stratum corneum: transepidermal water loss rose from approximately 8.8 g m-2 h-1 before wIRA irradiation to 14.2 g m-2 h-1 after wIRA irradiation and skin hydration rose from 67 to 87 relative units. Skin surface temperature increased from 32.8°C before wIRA to 36.4°C after wIRA irradiation. Discussion: The better penetration of the hydrophilic dye fluorescein after or during skin irradiation (modes B and C can be explained by increased hydration of the stratum corneum by irradiation with wIRA. Conclusions: As most topically applied substances for the treatment of patients are mainly hydrophilic, wIRA can be used to improve the penetration of substances before or after application of substances – in the first case even of thermolabile substances – with a broad clinical relevance as a contact free alternative to an occlusive dressing.

    The application into the rat conjunctiva of various phlogistic agents, such as croton oil, mustard oil and formaldehyde, elicits an increase of serum corticosterone linearly related to the log of the applied concentrations, so that from their parallelized regression lines it is possible to calculate the phlogistic potency of each tested agent in reference to croton oil. The time kinetic of such an increase (elicited by croton oil) is compared with that of two other parameters previously adopted as indirect quantitative indices of the phlogosis: the adrenal ascorbic acid depletion and the liver tyrosine-alpha-ketoglutarate transaminase increase. Serum corticosterone is shown to be the quickest and the most sensitive of the adopted indices, even if the phlogistic potency of the tested agents and the precision of these evaluations substantially coincides whatsoever the index adopted. Finally the pathways of adrenocortical activation are investigated and it is shown that the activation may be peripherally blocked by topical application of corticosteroids (but not of local anesthetics) and centrally by hypophysectomy or parenteral administration of pentobarbital plus morphine.

    Materials and Methods : Seventy eyes of 70 patients with primary pterygia were randomly allocated to two groups. The first group (Group A, 35 eyes received 0.1 ml of 0.15 mg/ml of subconjunctival MMC injected into the head of the pterygium 24 h before surgical excision with the bare sclera technique. The second group (Group B 35 eyes underwent surgical removal with the bare sclera technique with intraoperative application of MMC (0.15 mg/ml over bare sclera for 3 min. The study was performed between March 2007 and December 2008, and follow up was performed for 1 year postoperatively. Differences between frequencies in both groups were compared by the Chi-square test or Fisher exact test. Differences between means in both groups were compared by Student′s t-test. P 0.05. Postoperatively, scleral thinning occurred in one eye in each group that resolved by 5 months postoperatively. No serious postoperative complications occurred in either group. Conclusion : Preoperative local injection of 0.15 mg/ml MMC is as effective as intraoperative topical application of 0.15 mg/ml MMC for preventing pterygium recurrence after surgical removal.

  17. Non-occlusive topical exposure of human skin in vitro as model for cytotoxicity testing of irritant compounds.

    Lönnqvist, Susanna; Briheim, Kristina; Kratz, Gunnar

    2016-02-01

    Testing of irritant compounds has traditionally been performed on animals and human volunteers. Animal testing should always be restricted and for skin irritancy mice and rabbits hold poor predictive value for irritant potential in humans. Irritant testing on human volunteers is restricted by the duration subjects can be exposed, and by the subjectivity of interpreting the visual signs of skin irritation. We propose an irritant testing system using viable human full thickness skin with the loss of cell viability in the exposed skin area as end point measurement. Skin was exposed to sodium dodecyl sulfate (SDS) at 20% concentration by non-occluded topical exposure to establish a positive control response and subsequent test compounds were statistically compared with the 20% SDS response. Cell viability and metabolism were measured with 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The model presents correlation between increased concentration of SDS and decreased viability of cells in the exposed skin area (R(2) = 0.76). We propose the model to be used for cytotoxicity testing of irritant compounds. With fully intact barrier function, the model comprises all cells present in the skin with quantifiable end point measurement. PMID:26446981

    DEET (N,N-diethyl-3-methylbenzamide) is nowadays the most effective mosquito repellent available, however, its use can present some topical and systemic side effects. Some botanical compositions, as Andiroba (Carapa guianensis), have been proved repellent properties at low cost and toxicity. An experimental study was driven involving four volunteers submitting their forearms covered with Andiroba oil at 100%, DEET 50%, refined soy oil, Andiroba oil 15% and in the absence of products, directly to healthy females of Aedes sp. The times of first and third bites were checked. The results showed that the median of the first bite without any product was 17.5s and the third bite, 40.0s. In the soy oil, the bites happened in 60.0s and 101.5s, in the presence of Andiroba oil 100%, in 56.0s and 142.5s and in Andiroba oil 15%, in 63.0s and 97.5s. The volunteers using DEET 50% had not received bites after 3600s in most of the experiments (p Andiroba oil compared to the soy oil, forearm without product and Andiroba oil 15%, showed discreet superiority (p Andiroba oil presents discreet repellent effect against bite of Aedes sp., being significantly inferior to DEET 50%.

    Full Text Available Many critics consider Richard Serra the leading sculptor of the 20th century. He is famous not only for inventing something new in sculpture (abstract sculpture compositions existed before him, having been opened by constructivist vanguard of the beginning of the 20th century. Material selections by Vladimir Tatlin and sculptures by Osip Tsadkin, as well as compositions by Henry Moor appeared before Serra. Serra is famous for transferring his works' accent from the works as they are, which could be installed in any place, to their environment. That is he saw in the sculpture a key to understanding the urban space. His crude metal sheets and profiles, rectangular and curvilinear, exceeding regular scale of sculpture, come closer to architecture. Richard Serra places them near architectural constructions as checkpoints of intermediate scale category of space located between so-called «street furniture» – lamp posts, stalls, fountains and benches – and buildings, especially huge modern ones.But the matter is not only in the scale. Serra's sculptures are not only abstract compositions that harmoniously add to the space with their spacious scale. They have some mystery, some implicit sense appearing before a pedestrian as an enigma. Their mystique opposes both street furniture and architecture. But first of all it opposes the historical sculpture with its enigma always overshadowed by historical or biographical topic. Krylov's sculpture in the Summer Garden or Minin and Pozharsky's monument on the Red Square do not strike us, because we know that those monuments are erected IN COMMEMORATION of prominent people, as fellow citizens' tribute to their great contribution to the national history. But the crude metal sheets welded at different angles – what are they for? Who needs them?As an art critic, Edward Goldman, said, fame came to Richard Serra in 1989, when the sculpture composition Tilted Arc erected eight years before it was demolished by

  20. Facile fabrication of superhydrophobic flower-like polyaniline architectures by using valine as a dopant in polymerization

    Sun, Jun; Bi, Hong

    2012-03-01

    A facile method was developed to fabricate superhydrophobic, flower-like polyanline (PANI) architectures with hierarchical nanostructures by adding valine in polymerization as a dopant. The water contact angle of the prepared PANI film was measured to be 155.3°, and the hydrophobic surface of the PANI architectures can be tuned easily by varying the polymerization time as well as valine doping quantity. It is believed that valine plays an important role in not only growth of the hierarchical PANI structures but also formation of the superhydrophobic surface, for it provides functional groups such as sbnd COOH, sbnd NH2 and a hydrophobic terminal group which may further increase intra-/inter-molecular interactions including hydrogen bonding, π-π stacking and hydrophobic properties. Similar flower-like PANI architectures have been prepared successfully by employing other amino acids such as threonine, proline and arginine. This method makes it possible for widespread applications of superhydrophobic PANI film due to its simplicity and practicability.

  1. Physical process in OLED architectures with transparent carbon nanotube sheets as electrodes

    Science.gov (United States)

    Ovalle Robles, Raquel

    There has been a great deal of activity in the development of organic light emitting diodes (OLED's) and polymeric light emitting diodes (PLED's). Research in OLEDs and PLEDs have been having a significant development over the last few years towards commercialization, extended life time, stability, efficiency and new fabrication processes suitable for mass production are some of the topics. The potential for commercialization is high due to their low operating voltage (typically between 2.5 to 5 volts), their high brightness and their ease to process. They are light weight and can be flexible. Furthermore, these devices can be easily color tune to produce red, green and blue colors. Research in this type of electroluminescence devices has advanced rapidly and device prototypes now meet realistic specifications for applications. By proper device engineering these devices can achieve high electroluminescence efficiencies and lifetimes. In this research project we present several methods and procedures that we developed and use to produce OLEDs and PLEDs. We have incorporated quantum dots into OLEDs as emissive dopants that contribute to the control of the spectral distribution of emitted light allowing the production of white OLEDs using both a multilayer structure with emission from multiple layers and a bilayer structure with emission from only the quantum dots. We have also produced PLED devices with a new family of novel PPV polymers achieving high bright efficient devices. OLED structures with transparent carbon nanotube sheets, obtained by dry drawing from a CVD-grown forest have been produced. The devices shown to be very bright and the MCNT sheets are efficient hole-injecting anodes for OLEDs Also, for flexible display applications, there is a need for high strength, flexible materials which can be deposited as transparent films and can act as hole injectors for organic films. By using a hybrid ITO/MWCNT anode onto flexible substrates an enhancement of the

  2. THE DESIGN OF MOSQUES AS COMMUNITY DEVELOPMENT CENTERS FROM THE PERSPECTIVE OF THE SUNNA AND WRIGHT’S ORGANIC ARCHITECTURE

    Directory of Open Access Journals (Sweden)

    Mohamad Tajuddin Mohamad Rasdi, Nangkula Utaberta

    2012-03-01

    Full Text Available The main purpose of this paper is to present an alternative approach to mosque design with particular reference to the context of Malaysia and the Malay World or the Nusantara. The paper contains four main parts. The first part examines the problem of mosque architectural interpretation from the perspective of Western architectural historiography. The main problems highlighted are those which pertain to the idea of ‘architecture’, ‘religious architecture’, relevance of the body of knowledge known as the ‘Hadith’ and lastly the specific historical-political agenda of some traditional mosques. The second part of the paper expounds briefly a reinterpretation of the hadith in arguing that the mosque approaches more as a community development complex than that as a mere house of rituals. The third part of the paper examines Wright’s Organic Architecture with specific reference to the design of the Unity Church and a few other buildings as containing some important lessons of mosque designs from the perspective of the Sunnah. The final part of the paper uses the principles discussed to criticize the Putra Mosque and the Masjid Negara.

  5. The Role of Topical Brimonidine Tartrate Gel as a Novel Therapeutic Option for Persistent Facial Erythema Associated with Rosacea.

    Science.gov (United States)

    Johnson, Andrew William; Johnson, Sandra Marchese

    2015-09-01

    Rosacea is a chronic inflammatory skin condition that commonly presents with persistent facial erythema with or without the coincident presence of flushing, telangiectasias, inflammatory papules or pustules, phymatous changes, or ocular involvement. Patients often present with a constellation of various signs and symptoms of the disease, and an individualized treatment plan should be tailored to a patient's unique clinical presentation. Previously available medications for rosacea have all targeted the inflammatory erythematous papules and pustules frequently associated with the disease, leaving a therapeutic gap for the common manifestation of persistent facial erythema. Brimonidine tartrate 0.33% gel was approved by the US Food and Drug Administration in August 2013 as the first medication available for the topical treatment of persistent facial erythema associated with rosacea. Brimonidine gel is a highly selective α2-adrenergic receptor agonist with potent vasoconstrictive effects, which leads to significant reduction of persistent facial erythema in the majority of patients when applied once daily. Based on large-scale clinical trials and post-marketing reports, brimonidine gel has maintained a good safety profile with a minority of patients experiencing adverse effects from its use, most of which are cutaneous in nature, mild-to-moderate in degree, occur early after initiation of treatment, often resolve spontaneously with continued use, and generally resolve after discontinuation of use. Among the reported adverse effects, two distinct manifestations of worsened erythema have been described. Brimonidine gel can be integrated into a treatment regimen along with concomitant therapies for facial papules and pustules with no increased risk of adverse events with combination therapy. Education about optimal application methods, setting reasonable expectations for treatment, and minimizing inflammation are important factors for the successful use of brimonidine

    The development of topical microbicide formulations for vaginal delivery to prevent HIV-2 sexual transmission is urgently needed. Second- and third-generation polyanionic carbosilane dendrimers with a silicon atom core and 16 sulfonate (G2-S16), napthylsulfonate (G2-NS16) and sulphate (G3-Sh16) end-groups have shown potent and broad-spectrum anti-HIV-1 activity. However, their antiviral activity against HIV-2 and mode of action have not been probed. Cytotoxicity, anti-HIV-2, anti-sperm and antimicrobial activities of dendrimers were determined. Analysis of combined effects of triple combinations with tenofovir and raltegravir was performed by using CalcuSyn software. We also assessed the mode of antiviral action on the inhibition of HIV-2 infection through a panel of different in vitro antiviral assays: attachment, internalization in PBMCs, inactivation and cell-based fusion. Vaginal irritation and histological analysis in female BALB/c mice were evaluated. Our results suggest that G2-S16, G2-NS16 and G3-Sh16 exert anti-HIV-2 activity at an early stage of viral replication inactivating the virus, inhibiting cell-to-cell HIV-2 transmission, and blocking the binding of gp120 to CD4, and the HIV-2 entry. Triple combinations with tenofovir and raltegravir increased the anti-HIV-2 activity, consistent with synergistic interactions (CIwt: 0.33-0.66). No vaginal irritation was detected in BALB/c mice after two consecutive applications for 2 days with 3% G2-S16. Our results have clearly shown that G2-S16, G2-NS16 and G3-Sh16 have high potency against HIV-2 infection. The modes of action confirm their multifactorial and non-specific ability, suggesting that these dendrimers deserve further studies as potential candidate microbicides to prevent vaginal/rectal HIV-1/HIV-2 transmission in humans.

  11. Listening comprehension for sentences: the accessibility of referents for pronouns as a function of age, topic continuity, and pronoun emphasis.

    Kertoy, M K

    1991-12-01

    An auditory comprehension task was employed to determine how subjects (20 first graders, 20 fifth graders, and 20 adults) use topic continuity and contrastive emphasis in the assignment of referents for pronouns in sentences. Significant differences in performance for emphasized and unemphasized pronouns were found suggesting that subjects used contrastive emphasis when assigning referents for pronouns. Fifth graders overused the cue of topic continuity in assigning referents for emphasized pronouns. This effect has not been shown previously in studies of children's understanding of pronomial reference. An interaction between age and pronoun emphasis was also significant. This interaction suggests that developmental changes continued to take place in the learning of cues for resolving pronouns by school age children. PMID:1770333

  15. Asignifying Semiotics as Proto-Theory of Singularity: Drawing is Not Writing and Architecture does Not Speak

    Directory of Open Access Journals (Sweden)

    Andrej Radman

    2014-05-01

    Full Text Available We have recently witnessed a confession of a fellow architect with which we fully identify. We, too, belong to the generation educated under the semiotic regime, which – as we will argue in our introduction – has run its course. We also believe that the idea of ‘architecture as language’ might have been useful as an analytical tool but never as a design mechanism. After all, creativity comes first and routinisation follows. As the title of Footprint 14 suggests, this is a general plea to have done with the hegemony of the linguistic signifier. Signifying semiotics is but a fraction of a much broader asignifying semiotics. We propose to approach the issue qua Spinozist practice of ethology, defined as the study of capacities, or – as we would like to think of it – a proto-theory of singularity. This is as much an ethical or political problem as it is an aesthetic one. It concerns what the cultural critic Steven Shaviro recently qualified as a primordial form of sentience that is non-intentional, non-correlational, and anoetic. The Affective Turn will be measured against the unavoidable Digital Turn. We will conclude by reversing the famous Wittgensteinian dictum whereby what we cannot speak about we must not pass over in silence. A brief summary of contributions, which are by no means limited to architecture, is concluded with a politically charged epilogue. The very last paragraph of the epilogue reveals the pink-on-pink reference.

    This title adopts the view that physics is the primary driving force behind a number of developments in mathematics. Previously, science and mathematics were part of natural philosophy and many mathematical theories arose as a result of trying to understand natural phenomena. This situation changed at the beginning of last century as science and mathematics diverged. These two fields are collaborating once again; 'Topics in Mathematical Physics' takes the reader through this journey. The author discusses topics where the interaction of physical and mathematical theories has led to new points o

    2005-01-01

    The Project Integration Architecture (PIA) uses object-oriented technology to implement self-revelation and semantic infusion through class derivation. That is, the kind of an object can be discovered through program inquiry and the well-known, well-defined meaning of that object can be utilized as a result of that discovery. This technology has already been demonstrated by the PIA effort in its parameter object classes. It is proposed that, by building on this technology, an autonomous, automatic, goal-seeking, solution system may be devised.

  9. A Flexible LDPC code decoder with a Network on Chip as underlying interconnect architecture

    CERN Document Server

    Condo, Carlo

    2011-01-01

    LDPC (Low Density Parity Check) codes are among the most powerful and widely adopted modern error correcting codes. The iterative decoding algorithms required for these codes involve high computational complexity and high processing throughput is achieved by allocating a sufficient number of processing elements (PEs). Supporting multiple heterogeneous LDPC codes on a parallel decoder poses serious problems in the design of the interconnect structure for such PEs. The aim of this work is to explore the feasibility of NoC (Network on Chip) based decoders, where full flexibility in terms of supported LDPC codes is obtained resorting to an NoC to connect PEs. NoC based LDPC decoders have been previously considered unfeasible because of the cost overhead associated to packet management and routing. On the contrary, the designed NoC adopts a low complexity routing, which introduces a very limited cost overhead with respect to architectures dedicated to specific classes of codes. Moreover the paper proposes an effic...

    2014-05-01

    The improvements in the hardware and software of communication devices have allowed running Virtual Reality (VR) and Augmented Reality (AR) applications on those. Nowadays, it is possible to overlay synthetic information on real images, or even to play 3D on-line games on smart phones or some other mobile devices. Hence the use of 3D data for business and specially for education purposes is ubiquitous. Due to always available at hand and always ready to use properties of mobile phones, those are considered as most potential communication devices. The total numbers of mobile phone users are increasing all over the world every day and that makes mobile phones the most suitable device to reach a huge number of end clients either for education or for business purposes. There are different standards, protocols and specifications to establish the communication among different communication devices but there is no initiative taken so far to make it sure that the send data through this communication process will be understood and used by the destination device. Since all the devices are not able to deal with all kind of 3D data formats and it is also not realistic to have different version of the same data to make it compatible with the destination device, it is necessary to have a prevalent solution. The proposed architecture in this paper describes a device and purpose independent 3D data visibility any time anywhere to the right person in suitable format. There is no solution without limitation. The architecture is implemented in a prototype to make an experimental validation of the architecture which also shows the difference between theory and practice.

    Sayyed, Ali; de Araújo, Gustavo Medeiros; Bodanese, João Paulo; Becker, Leandro Buss

    2015-01-01

    The use of mobile nodes to collect data in a Wireless Sensor Network (WSN) has gained special attention over the last years. Some researchers explore the use of Unmanned Aerial Vehicles (UAVs) as mobile node for such data-collection purposes. Analyzing these works, it is apparent that mobile nodes used in such scenarios are typically equipped with at least two different radio interfaces. The present work presents a Dual-Stack Single-Radio Communication Architecture (DSSRCA), which allows a UAV to communicate in a bidirectional manner with a WSN and a Sink node. The proposed architecture was specifically designed to support different network QoS requirements, such as best-effort and more reliable communications, attending both UAV-to-WSN and UAV-to-Sink communications needs. DSSRCA was implemented and tested on a real UAV, as detailed in this paper. This paper also includes a simulation analysis that addresses bandwidth consumption in an environmental monitoring application scenario. It includes an analysis of the data gathering rate that can be achieved considering different UAV flight speeds. Obtained results show the viability of using a single radio transmitter for collecting data from the WSN and forwarding such data to the Sink node. PMID:26389911

  16. The cellular architecture of the larval zebrafish tectum, as revealed by Gal4 enhancer trap lines

    2009-10-01

    Full Text Available We have carried out a Gal4 enhancer trap screen in zebrafish, and have generated 184 stable transgenic lines with interesting expression patterns throughout the nervous system. Of these, three display clear expression in the tectum, each with a distinguishable and stereotyped distribution of Gal4 expressing cells. Detailed morphological analysis of single cells, using a genetic “Golgi-like” labelling method, revealed four common cell types (superficial, periventricular, shallow periventricular, and radial glial, along with a range of other less common neurons. The shallow periventricular and a subset of the periventricular neurons are tectal efferent neurons that target various parts of the reticular formation. We find that it is specifically periventricular neurons with dendrites in the deep tectal neuropil that target the reticular formation. This indicates that these neurons receive the tectum’s highly processed visual information (which is fed from the superficial retinorecipient layers, and relay it to premotor regions. Our results show that the larval tectum, both broadly and at the single cell level, strongly resembles a miniature version of its adult counterpart, and that it has all of the necessary anatomical characteristics to inform motor responses based on sensory input. We also demonstrate that mosaic expression of GFP in Gal4 enhancer trap lines can be used to describe the types and abundance of cells in an expression pattern, including the architectures of individual neurons. Such detailed anatomical descriptions will be an important part of future efforts to describe the functions of discrete tectal circuits in the generation of behavior.

    2012-12-01

    Full Text Available The aim of this study was to evaluate the efficacy of a hyaluronic acid containing eye drop in ameliorating ocular surface pathology and discomfort in canine keratoconjunctivitis sicca (KCS. Twenty five dogs with KCS treated with a topical carbomer (CA-based tear replacement gel were moved to treatment with a hyaluronic acid (HA-containing tear replacement eye drop. Dogs were subject to a full ophthalmic examination at the beginning of the study and after two and four weeks of treatment, Schirmer tear tests (STTs were performed at each examination. Conjunctival hyperemia, ocular discharge and ocular irritation were evaluated and scored on a 0-3 semi-quantitative scale. Values were compared before and after 4 weeks of treatment using a paired t-test. Evaluation scores were compared using the Wilcoxon signed rank test. The transfer from CA-based to HA-containing tear replacement significantly decreased the conjunctival hyperemia score from 2.12 ± 0.73 to 1.26 ± 0.59 and ocular discomfort was lowered from 2.11 ± 0.97 to 0.93 ± 0.75. Ocular discharge was reduced from a score of 1.04 ± 0.82 to 0.70 ± 0.53, however, the decrease did not reach statistical significance. Schirmer tear test was increased with statistical significance (p < 0.001 but given that the increase was only from 5.42 ± 3.50 to 6.19 ± 3.86 mm min-1; this was not considered clinically significant. This study demonstrated that HA-containing eye drops used twice daily in dogs with KCS had greater ameliorative effects on ocular surface health and discomfort than did CA-based topical gels used as or more frequently.

    Kupetsky, Erine; Houston, Neil A.M.

    2016-01-01

    Background: Calcipotriene/betamethasone topical suspension is a topical therapy that is often used as monotherapy as a first-line treatment for plaque psoriasis. The objective of this preliminary, open label, single arm study was to determine the efficacy of adding a topical suspension to a traditional systemic therapy for psoriasis, either methotrexate or acitretin. Methods: In this exploratory study, eight patients with chronic plaque psoriasis who were on stable methotrexate or acitretin treatment without clearance were treated with once-daily calcipotriene/betamethasone topical suspension. Subjects completed five study visits over 12 weeks. Primary outcome measure was improvement of two or more points in Investigator Global Assessment. Secondary endpoints included change in Body Surface Area, Dermatology Life Quality Index, and Patient’s Global Assessment from baseline to Week 12. Results: Overall, the median decrease in Investigator Global Assessment over 12 weeks was 1.5 points, with 50 percent of subjects experiencing a drop of two or more points in Investigator Global Assessment. All eight subjects had a reduction in Body Surface Area and Patient’s Global Assessment. There was a mean decrease in Dermatology Life Quality Index score of 78.9 percent, showing improved patient quality of life. In addition, all patients tolerated the treatment well and 6 of 8 patients had improved satisfaction level with their treatment by the end of the study. Conclusion: The topical suspension was effective and well-tolerated in conjunction with stable methotrexate or acitretin treatment in all eight patients in this study. These results support the feasibility of a larger scale study to further investigate the efficacy of these treatment combinations. The trial is registered at ClinicalTrials.gov, number NCT01761019.

  3. Asignifying Semiotics as Proto-Theory of Singularity: Drawing is Not Writing and Architecture does Not Speak

    Directory of Open Access Journals (Sweden)

    Deborah Hauptmann

    2014-10-01

    Full Text Available We have recently witnessed a confession of a fellow architect with which we fully identify. We, too, belong to the generation educated under the semiotic regime, which – as we will argue in our introduction – has run its course. We also believe that the idea of ‘architecture as language’ might have been useful as an analytical tool but never as a design mechanism. After all, creativity comes first and routinisation follows. As the title of Footprint 14 suggests, this is a general plea to have done with the hegemony of the linguistic signifier. Signifying semiotics is but a fraction of a much broader asignifying semiotics. We propose to approach the issue qua Spinozist practice of ethology, defined as the study of capacities, or – as we would like to think of it – a proto-theory of singularity. This is as much an ethical or political problem as it is an aesthetic one. It concerns what the cultural critic Steven Shaviro recently qualified as a primordial form of sentience that is non-intentional, non-correlational, and anoetic. The Affective Turn will be measured against the unavoidable Digital Turn. We will conclude by reversing the famous Wittgensteinian dictum whereby what we cannot speak about we must not pass over in silence. A brief summary of contributions, which are by no means limited to architecture, is concluded with a politically charged epilogue. The very last paragraph of the epilogue reveals the pink-on-pink reference

    Nature-approximating landscape architecture (NALA) is a concept of sustainable development as applied to landscape architecture, while the urban habitants' awareness and acceptance of NALA idea is the key for the successful application of NALA. Through semi-structured interview, this paper explored the attitudes of the habitants in Hongshan District of Wuhan City toward the NALA design and management, and the influence of the social-economic characteristics of the responders on their attitudes toward the NALA. A fairly low percentage of the responders approved of the NALA design (10.3% - 46.9%) and management (7.4% - 34.9%). The attitudes towards NALA design were mainly affected by the responders' age, and the attitudes toward NALA management were significantly correlated with the responders' age, educational level, and profession. The efficient cause why a large number of responders did not support the NALA was that these responders attached importance to the aesthetic effect of green space, and preferred cleanliness and order. The lack of related ecological knowledge and environmental awareness was the root cause of the lesser support towards NALA. To establish NALA demonstration bases and to intensify the publicity and education of NALA idea and related ecological knowledge could promote an increasing number of urban habitants actively participating in NALA construction.

    The control of flowering is not only important for reproduction,but also plays a key role in the processes of domestication and adaptation.To reveal the genetic architecture for flowering time and photoperiod sensitivity,a comprehensive evaluation of the relevant literature was performed and followed by meta analysis.A total of 25 synthetic consensus quantitative trait loci (QTL) and four hot-spot genomic regions were identified for photoperiod sensitivity including 11 genes related to photoperiod response or flower morphogenesis and development.Besides,a comparative analysis of the QTL for flowering time and photoperiod sensitivity highlighted the regions containing shared and unique QTL for the two traits.Candidate genes associated with maize flowering were identified through integrated analysis of the homologous genes for flowering time in plants and the consensus QTL regions for photoperiod sensitivity in maize (Zea mays L.).Our results suggest that the combination of literature review,meta-analysis and homologous blast is an efficient approach to identify new candidate genes and create a global view of the genetic architecture for maize photoperiodic flowering.Sequences of candidate genes can be used to develop molecular markers for various models of marker-assisted selection,such as marker-assisted recurrent selection and genomic selection that can contribute significantly to crop environmental adaptation.

    2015-02-01

    In applications we may want to compare different document collections: they could have shared content but also different and unique aspects in particular collections. This task has been called comparative text mining or cross-collection modeling. We present a differential topic model for this application that models both topic differences and similarities. For this we use hierarchical Bayesian nonparametric models. Moreover, we found it was important to properly model power-law phenomena in topic-word distributions and thus we used the full Pitman-Yor process rather than just a Dirichlet process. Furthermore, we propose the transformed Pitman-Yor process (TPYP) to incorporate prior knowledge such as vocabulary variations in different collections into the model. To deal with the non-conjugate issue between model prior and likelihood in the TPYP, we thus propose an efficient sampling algorithm using a data augmentation technique based on the multinomial theorem. Experimental results show the model discovers interesting aspects of different collections. We also show the proposed MCMC based algorithm achieves a dramatically reduced test perplexity compared to some existing topic models. Finally, we show our model outperforms the state-of-the-art for document classification/ideology prediction on a number of text collections. PMID:26353238

    Full Text Available As we know very well that in present days, computer is the basic need of every common man and they have to use it for time saving and to minimize human labour, rather than they also need to aware about its harmful impacts on the environment. In this research paper we take various factors related to the awareness of green computing. Present desktop computers gives extremely powerful performance since they are equipped with blazing 2 GHz dual-core or core to duo processors and high-performance memory. However, mostly users rarely need the capacity of operation more than 5 percent of available computing capacity – the rest is wasted. It would be possible to achieve significant environment and cost savings by sharing this excess or waste power by many users simultaneously. NComputing seized on this idea by which minimize the power consumption. Power consumption by the computers is the major issue in current industries and data centres.

    Full Text Available Amphibians have played a key role in the elucidation of the mechanisms of early development over the last century. Much of our knowledge about the mechanisms of vertebrate early development comes from studies using Xenopus laevis. Xenopus sp. is a major contributor to our understanding of cell biological and biochemical processes, including: (1 chromosome replication; (2 chromatin, cytoskeleton and nuclear assembly; (3 cell cycle progression and (4 intracellular signaling. Amphibian embryos remained the embryos of choice for experimental embryology for many decades. European embryologists used predominantly urodele embryos (such as Triturus and embryos of the frog Rana temporaria, which is related to the North American species Rana pipiens. Using light, fluorescence, transmission electron microscopy (TEM and molecular investigations, some peculiar aspects of chromatin and chromosome organization and evolution in oogenesis and spermatogenesis of amphibians were investigated. We have focused our investigations on dynamics of the chromatin structure in different stages of development.

  16. Design of Decorated Self-Assembling Peptide Hydrogels as Architecture for Mesenchymal Stem Cells

    Directory of Open Access Journals (Sweden)

    Annj Zamuner

    2016-08-01

    Full Text Available Hydrogels from self-assembling ionic complementary peptides have been receiving a lot of interest from the scientific community as mimetic of the extracellular matrix that can offer three-dimensional supports for cell growth or can become vehicles for the delivery of stem cells, drugs or bioactive proteins. In order to develop a 3D “architecture” for mesenchymal stem cells, we propose the introduction in the hydrogel of conjugates obtained by chemoselective ligation between a ionic-complementary self-assembling peptide (called EAK and three different bioactive molecules: an adhesive sequence with 4 Glycine-Arginine-Glycine-Aspartic Acid-Serine-Proline (GRGDSP motifs per chain, an adhesive peptide mapped on h-Vitronectin and the growth factor Insulin-like Growth Factor-1 (IGF-1. The mesenchymal stem cell adhesion assays showed a significant increase in adhesion and proliferation for the hydrogels decorated with each of the synthesized conjugates; moreover, such functionalized 3D hydrogels support cell spreading and elongation, validating the use of this class of self-assembly peptides-based material as very promising 3D model scaffolds for cell cultures, at variance of the less realistic 2D ones. Furthermore, small amplitude oscillatory shear tests showed that the presence of IGF-1-conjugate did not alter significantly the viscoelastic properties of the hydrogels even though differences were observed in the nanoscale structure of the scaffolds obtained by changing their composition, ranging from long, well-defined fibers for conjugates with adhesion sequences to the compact and dense film for the IGF-1-conjugate.

    2016-02-01

    The primary treatment for superficial fungal infections is antifungal topical formulations, and allylamines and azoles represent the two major classes of topical formulations that are used to treat these infections. The stratum corneum (SC) is composed of keratinocytes that are surrounded by a matrix of lipids. The efficacy of topically applied formulations depends on their ability to penetrate this lipid matrix, and the vehicle plays an integral role in the penetration of active molecule into skin. There are several challenges to formulating topical drugs, which include the biotransformation of the active molecules as they pass through the SC and the physical changes that occur to the vehicle itself when it is applied to the skin. This article will review current and emerging topical antifungal vehicles. PMID:26885798

    Executable Architectures allow the evaluation of system architectures not only regarding their static, but also their dynamic behavior. However, the systems engineering community do not agree on a common formal specification of executable architectures. To close this gap and identify necessary elements of an executable architecture, a modeling language, and a modeling formalism is topic of ongoing PhD research. In addition, systems are generally defined and applied in an operational context to provide capabilities and enable missions. To maximize the benefits of executable architectures, a second PhD effort introduces the idea of creating an executable context in addition to the executable architecture. The results move the validation of architectures from the current information domain into the knowledge domain and improve the reliability of such validation efforts. The paper presents research and results of both doctoral research efforts and puts them into a common context of state-of-the-art of systems engineering methods supporting more agility.

    Sunburn, immune suppression, photo-aging, and skin cancers result from uncontrolled overexposure of human skin to solar ultraviolet radiation (UVR). Preventive measures, including photo-protection, are helpful and can be achieved by topical sun-screening agents. Polypodium leucotomos (PL) has been used for the treatment of inflammatory diseases and has shown some in vitro and in vivo immunomodulating properties. Its beneficial photo-protective effects in the treatment of vitiligo and its antioxidant properties encouraged us to evaluate in vivo the potentially useful photo-protective property of natural extract of PL after topical application or oral ingestion. Twenty-one healthy volunteers [either untreated or treated with oral psoralens (8-MOP or 5-MOP)] were enrolled in this study and exposed to solar radiation for evaluation of the following clinical parameters: immediate pigment darkening (IPD), minimal erythema dose (MED), minimal melanogenic dose (MMD), and minimal phototoxic dose (MPD) before and after topical or oral administration of PL. Immunohistochemical assessment of CD1a-expressing epidermal cells were also performed. PL was found to be photo-protective after topical application as well as oral administration. PL increased UV dose required for IPD (P<0.01), MED (P<0.001) and MPD (P<0.001). After oral administration of PL, MED increased 2.,8{+-}0.59 times and MPD increased 2.75{+-}0.5 and 6.8{+-}1.3 times depending upon the type of psoralen used. Immunohistochemical study revealed photo-protection of Langherhans cells by oral as well as topical PL. The observed photo-protective activities of oral or topical PL reveal a new avenue in examining the potentially useful field of systemic photo-protection and suggests that PL can be used as adjunct treatment and can make photochemotherapy and phototherapy possibly safe and effective when the control of cutaneous phototoxicity to PUVA or UVB is a limiting factor in such photo-therapies.

  2. Architectural geometry

    Pottmann, Helmut

    2014-11-26

    Around 2005 it became apparent in the geometry processing community that freeform architecture contains many problems of a geometric nature to be solved, and many opportunities for optimization which however require geometric understanding. This area of research, which has been called architectural geometry, meanwhile contains a great wealth of individual contributions which are relevant in various fields. For mathematicians, the relation to discrete differential geometry is significant, in particular the integrable system viewpoint. Besides, new application contexts have become available for quite some old-established concepts. Regarding graphics and geometry processing, architectural geometry yields interesting new questions but also new objects, e.g. replacing meshes by other combinatorial arrangements. Numerical optimization plays a major role but in itself would be powerless without geometric understanding. Summing up, architectural geometry has become a rewarding field of study. We here survey the main directions which have been pursued, we show real projects where geometric considerations have played a role, and we outline open problems which we think are significant for the future development of both theory and practice of architectural geometry.

  3. Topical rapamycin as a treatment for fibrofolliculomas in Birt-Hogg-Dube syndrome: a double-blind placebo-controlled randomized split-face trial.

    Directory of Open Access Journals (Sweden)

    Lieke M C Gijezen

    Full Text Available BACKGROUND: Birt-Hogg-Dubé syndrome (BHD is a rare autosomal dominant disorder characterised by the occurrence of benign, mostly facial, skin tumours called fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax and an increased renal cancer risk. Current treatments for fibrofolliculomas have high rates of recurrence and carry a risk of complications. It would be desirable to have a treatment that could prevent fibrofolliculomas from growing. Animal models of BHD have previously shown deregulation of mammalian target of rapamycin (mTOR. Topical use of the mTOR inhibitor rapamycin is an effective treatment for the skin tumours (angiofibromas in tuberous sclerosis complex, which is also characterised by mTOR deregulation. In this study we aimed to determine if topical rapamycin is also an effective treatment for fibrofolliculomas in BHD. METHODS: We performed a double blinded, randomised, facial left-right controlled trial of topical rapamycin 0.1% versus placebo in 19 BHD patients. Trial duration was 6 months. The primary outcome was cosmetic improvement as measured by doctors and patients. Changes in fibrofolliculoma number and size were also measured, as was occurrence of side effects. RESULTS: No change in cosmetic status of fibrofolliculomas was reported in the majority of cases for the rapamycin treated (79% by doctors, 53% by patients as well as the placebo treated facial sides (both 74%. No significant differences between rapamycin and placebo treated facial halves were observed (p = 1.000 for doctors opinion, p = 0.344 for patients opinion. No significant difference in fibrofolliculoma number or change in size of the fibrofolliculomas was seen after 6 months. Side effects occurred more often after rapamycin treatment (68% of patients than after placebo (58% of patients; p = 0.625. A burning sensation, erythema, itching and dryness were most frequently reported. CONCLUSIONS: This study provides no evidence that

    High resolution cryo-electron tomography (cryo-ET) was utilized to visualize Treponema pallidum, the causative agent of syphilis, at the molecular level. Three-dimensional (3-D) reconstructions from 304 infectious organisms revealed unprecedented cellular structures of this unusual member in the spirochetal family. High resolution cryo-ET reconstructions provided the detailed structures of the cell envelope, which is significantly different from that of gram-negative bacteria. The 4 nm lipid bilayer of both outer and cytoplasmic membranes resolved in 3-D reconstructions, providing an important marker for interpreting membrane-associated structures. Abundant lipoproteins cover the outer leaflet of the cytoplasmic membrane, in contrast to the rare outer membrane proteins visible by scanning probe microscopy. High resolution cryo-ET images also provided the first observation of T. pallidum chemoreceptor arrays, as well as structural details of the periplasmically located, cone-shaped structure at both ends of bacterium. Furthermore, 3-D subvolume averages of the periplasmic flagellar motors and filaments from living organisms revealed the novel flagellar architectures that may facilitate their rotation within the confining periplasmic space. Together, our findings provide the most detailed structural understanding of the periplasmic flagella and the surrounding cell envelope, which enable this enigmatic bacterium to efficiently penetrate tissue and escape host immune responses.

  6. THE EMERGENCE AND EVOLUTION OF ARABESQUE AS A MULTICULTURAL STYLISTIC FUSION IN ISLAMIC ART: THE CASE OF TURKISH ARCHITECTURE

    Directory of Open Access Journals (Sweden)

    Murat Cetin, M. Arif Kamal

    2012-04-01

    Full Text Available This paper elucidates the emergence and evolution of arabesque with specific reference to  the case of arabesque in Turkish art and architecture. It is argued here that arabesque is a fusion of styles rather than a pure and homogenous style. Furthermore, the paper aims to show that although the arabesque style appears to be a fanciful and freely organized manner of artistic treatment it is based on a very complex mathematical logic which is expressed through abstractionism. In this context, the grammar of geometry is elaborately used in the  implementation  of abstraction. Here, general characteristics as well as different modes or  types  of arabesque are discussed. Starting with the etymological roots of the term, the  history of its use in the literature  is  explored  through  the  paper. After  the  inquiry  of  its  material  and  pragmatic  aspects,  the development of the arabesque style is evaluated with regard to its transformations that took place along with its injection to Anatolia and mixing with Turkish culture. Finally, the morphological character of this fusion is put forward.   Keyword: Morphological character, geometry, fusion of styles, arabesque

Vitreous body as a natural substance has some properties which seem to make it superior to authologous blood for the management of severe dry eye syndrome and even persistent epithelial defect. This theory is based on some clues listed as below:"nVitreous contains a high amount of water and little macromolecules, the character suitable for a substance to be used for relieving symptoms of dry eye as a wetting effect. Moreover, it contains some growth factors such as insulin like growth factors and pigment epithelium-derived factor and high amount of viscous materials such as Chondroitin Sulfates and Hyaloronic acids, all are compounds seems to be effective in the management of dry eye and acceleration of epithelialization. It has also anti-inflammatory features. The most important unique feature of vitreous in comparison with blood is its immune privilege property documented by previous studies. Vitreous can be obtained from brain dead patients and also from eye banks easily.  As with all transplanted material of human origin, it carries risks of prion transmission; however, for intractable severe dry eye, benefits may greatly exceed the risk.

    Full Text Available ANGIPARSTM is a new herbal extract which has been produced in oral, topical, and intravenous forms. The present article contains preliminary results of the study which was planned to evaluate the efficacy and safety of orally applied ANGIPARSTM and to compare it with the combination of oral and topical forms and also with conventional therapy in patients with diabetic ulcers of the lower extremities."nTwenty one patients with diabetic foot ulcers were divided into 3 groups. The first group received 100 mg of oral ANGIPARSTM twice a day for 6 weeks in addition to conventional therapies. In the second group, ANGIPARSTM gel 3% was added to the oral form of the same product besides the conventional therapies for the same period of time. Finally, in the third group which was considered as control, only conventional therapies were performed. The patients were followed for 6 weeks. Parameters such as granulation tissue formation, skin epithelization, and wound surface areas changes were analyzed to determine the effectiveness of the compound in wounds healing. Furthermore, drug safety was assessed by monitoring adverse events and by clinical and laboratory evaluations."nThe study data showed significant differences between the intervention and control groups with respect to efficacy and tolerability. In each intervention group, primary wound healings occurred following 2 weeks. Complete wound healing which was greater than 70% improvement in wounds surface areas was achieved in 83% and 100% of group 1 and group 2 participants, respectively after 6 weeks. On the other hand, at the same period of time, only 22.2% of patients in control group revealed complete healing. Therefore, ANGIPARSTM had significant positive effect in increasing the incidence of complete wound closure compared with control group (p = 0.042. However, our evaluations indicated that adding topical treatment with 3% gel once a day to the oral therapy with the same product did not make

Design and architecture represent – at least in Denmark – also quite different disciplinary traditions and methods. Where designers develop prototypes......, architects tend to work with models and plans that are not easily understood by lay people. Further, many architects are themselves sceptical towards notions of user-involvement and collaborative design. They fear that the imagination of citizens and users is restricted to what they are already familiar with...

    An electronics architecture has been developed to enable the rapid construction and testing of prototypes of robotic systems. This architecture is designed to be a research vehicle of great stability, reliability, and versatility. A system according to this architecture can easily be reconfigured (including expanded or contracted) to satisfy a variety of needs with respect to input, output, processing of data, sensing, actuation, and power. The architecture affords a variety of expandable input/output options that enable ready integration of instruments, actuators, sensors, and other devices as independent modular units. The separation of different electrical functions onto independent circuit boards facilitates the development of corresponding simple and modular software interfaces. As a result, both hardware and software can be made to expand or contract in modular fashion while expending a minimum of time and effort.

  17. Architecture of Kepler's multi-transiting systems. II. New investigations with twice as many candidates

    International Nuclear Information System (INIS)

    We report on the orbital architectures of Kepler systems having multiple-planet candidates identified in the analysis of data from the first six quarters of Kepler data and reported by Batalha et al. (2013). These data show 899 transiting planet candidates in 365 multiple-planet systems and provide a powerful means to study the statistical properties of planetary systems. Using a generic mass-radius relationship, we find that only two pairs of planets in these candidate systems (out of 761 pairs total) appear to be on Hill-unstable orbits, indicating ∼96% of the candidate planetary systems are correctly interpreted as true systems. We find that planet pairs show little statistical preference to be near mean-motion resonances. We identify an asymmetry in the distribution of period ratios near first-order resonances (e.g., 2:1, 3:2), with an excess of planet pairs lying wide of resonance and relatively few lying narrow of resonance. Finally, based upon the transit duration ratios of adjacent planets in each system, we find that the interior planet tends to have a smaller transit impact parameter than the exterior planet does. This finding suggests that the mode of the mutual inclinations of planetary orbital planes is in the range 1.°0-2.°2, for the packed systems of small planets probed by these observations.

    The paper presents an ongoing research project that aims to help individuals with mild psychological disorders, like depression, to reduce the use of medication and escape a possible addiction to drugs by transforming their immediate or broader living space into a sensponsive environment. It is an innovative, multidisciplinary, non-invasive approach through the domains of architecture, computer science, psychology and endocrinology. Initially, the paper presents the connections between space and human behavior, and specifically, the ways in which the spatial qualities of the surrounding environment affect the human senses and consequently the hormonal changes and the production of the corresponding emotions and actions. As a next step, the paper outlines the creation of sensponsive environments that are programmed to sense human discomfort by monitoring changes in facial expression and body movement and respond to them accordingly by transforming their spatial elements in order to make people feel better. The proposed sensponsive spaces are equipped with biomedical monitoring systems, smart materials and sensor-actuator assemblies with programmed re-actions (haptic, olfactory, chromatic and so on) that help people refine their feeling of the surrounding space, guiding its smooth transition to a comfortable--for the body and the mind-place. The paper concludes with the next step of this research initiative, the sensponsive suit, a personalized wearable assembly enhanced with technology to positively affect the psychological health of the wearer.

  20. A new architecture as transparent electrodes for solar and IR applications based on photonic structures via soft lithography

    2011-01-01

    Transparent conducting electrodes with the combination of high optical transmission and good electrical conductivity are essential for solar energy harvesting and electric lighting devices. Currently, indium tin oxide (ITO) is used because ITO offers relatively high transparency (>80%) to visible light and low sheet resistance (Rs = 10 ohms/square (Ω /2)) for electrical conduction. However, ITO is costly due to limited indium reserves, and it is brittle. These disadvantages have motivated the search for other conducting electrodes with similar or better properties. There has been research on a variety of electrode structures involving carbon nanotube networks, graphene films, nanowire and nanopatterned meshes and grids. Due to their novel characteristics in light manipulation and collection, photonic crystal structures show promise for further improvement. Here, we report on a new architecture consisting of nanoscale high aspect ratio metallic photonic structures as transparent electrodes fabricated via a combination of processes. For (Au) and silver (Ag) structures, the visible light transmission can reach as high as 80%, and the sheet resistance of the structure can be as low as 3.2Ω /2. The optical transparency of the high aspect ratio metal structures at visible wavelength range is comparable to that of ITO glass, while their sheet resistance is more than 3 times lower, which indicates a much higher electrical conductivity of the metal structures. Furthermore, the high aspect ratio metal structures have very high infrared (IR) reflection (90%) for the transverse magnetic (TM) mode, which can lead to the development of fabrication of metallic structures as IR filters for heat control applications. Investigations of interdigitated structures based on the high aspect ratio metal electrodes are ongoing to study the feasibility in smart window applications in light transmission modulation.

    The effect of SLN incorporation on transdermal delivery and in vitro antiherpetic activity of Artemisia arborescens essential oil was investigated. Two different SLN formulations were prepared using the hot – pressure homogenization technique, Compritol 888 ATO as lipid, and Poloxamer 188 and Miranol Ultra C32 as surfactants. Formulations were examined for their stability for two years by monitoring average size distribution and zeta potential values. The antiviral activity of free and SLN incorporated essential oil was tested in vitro against Herpes Simplex Virus-1 (HSV-1) by a quantitative tetrazolium-based colorimetric method (MTT), while the effects of essential oil incorporation into SLN on both the permeation through and the accumulation into the skin strata was investigated by using in vitro diffusion experiments through newborn pig skin and an almond oil Artemisia essential oil solution as a control. Results showed that both SLN formulations were able to entrap the essential oil in high yields and that the mean particle size increased only slightly after two years of storage, indicating a high physical stability. In vitro antiviral assays showed that SLN incorporation did not affect the essential oil antiherpetic activity. The in vitro skin permeation experiments demonstrated the capability of SLN of greatly improving the oil accumulation into the skin, while oil permeation occurred only when the oil was delivered from the control solution.

    Graph mining has been a popular research area because of its numerous application scenarios. Many unstructured and structured data can be represented as graphs, such as, documents, chemical molecular structures, and images. However, an issue in relation to current research on graphs is that they cannot adequately discover the topics hidden in graph-structured data which can be beneficial for both the unsupervised learning and supervised learning of the graphs. Although topic models have proved to be very successful in discovering latent topics, the standard topic models cannot be directly applied to graph-structured data due to the "bag-of-word" assumption. In this paper, an innovative graph topic model (GTM) is proposed to address this issue, which uses Bernoulli distributions to model the edges between nodes in a graph. It can, therefore, make the edges in a graph contribute to latent topic discovery and further improve the accuracy of the supervised and unsupervised learning of graphs. The experimental results on two different types of graph datasets show that the proposed GTM outperforms the latent Dirichlet allocation on classification by using the unveiled topics of these two models to represent graphs.

  6. Active ingredients in sunscreens act as topical penetration enhancers for the herbicide 2,4-dichlorophenoxyacetic acid

    International Nuclear Information System (INIS)

    Agricultural workers are encouraged to use sunscreen to decrease the risk of UV-related skin cancer. Our previous studies have shown certain commercial sunscreens to be penetration enhancers. The focus of this project is to determine whether active ingredients in sunscreen formulations (i.e., the UV absorbing components and insect repellants for the sunscreen/bug repellant combinations) also act as dermal penetration enhancers for herbicides in vitro. The total percentages of 2,4-dichlorophenoxyacetic acid (2,4-D) penetrating through hairless mouse skin in 24 h ranged from 54.9 ± 4.7 for the no sunscreen control to 86.9 ± 2.5 for padimate-o. Of the active ingredients tested (7.5% octyl methoxycinnamate, 7% octocrylene, 0.6% oxybenzone, 5% homosalate, 5% octyl salicylate, 8% padimate-o, 10% sulisobenzone, and 9.5% and 19% N,N-diethyl-m-toluamide [DEET]), all but octocrylene led to a significant increase in total 2,4-D penetration as compared to the control (P 3H2O penetration across mouse skin, indicating physical damage to the stratum corneum. Additional studies demonstrated that the penetration enhancement seen across hairless mouse skin also occurred with human skin. Thus, the active ingredients of sunscreen formulations enhance dermal penetration of the moderately lipophilic herbicide 2,4-D

  7. The future of topical analgesics.

    Arnstein, Paul M

    2013-07-01

    Topically applied analgesic therapies have been used throughout history to treat a variety of patient conditions that present with pain. Before modem pharmaceuticals became readily available, mud-based emollients, salves, cold therapies, and other natural remedies were often used. Now we have effective therapies and are developing advanced topical analgesics as we learn more about the physiology and pathophysiology of pain. The use of topical analgesics may be associated with fewer patient systemic side effects than are seen with oral, parenteral, or transdermally administered agents, making the topical route of administration attractive to prescribers and patients. With further refinement of existing drugs and the development of novel agents, topical analgesics may offer relief for treating patient pain conditions that are currently challenging to treat, such as pain resulting from burns, wound debridement, and pressure ulcers. Recognizing the value of a multimodal approach, topical analgesics may offer a therapeutic option that can become part of a comprehensive treatment plan for the patient. With continued advancements in targeted drug-delivery systems, topical analgesics may be able to provide a method to prevent or reverse the phenomena of peripheral and central sensitization, or the neuroplastic changes believed to be responsible for the transition from acute to chronic pain states in patients. For those patients at risk for developing chronic pain states, such as complex regional pain syndrome, the combination of cutaneous stimulation (achieved through rubbing during application) and analgesic effects produced by the drug itself may prevent the disabling pain that often emerges during the subacute phase of disease. In summary, better utilization of currently available topical analgesics and continued research promise to ensure that topical analgesics are, and will continue to be, important tools in the treatment of patients with resistant pain.

  8. Temporary shelter-in-place as protection against a release of airborne hazardous material : report of a literature search.; TOPICAL

    International Nuclear Information System (INIS)

    ''Temporary shelter-in place'' is the combination of prompt shelter-in-place (SIP) to minimize initial exposure to airborne hazardous material, followed by timely action to terminate this protection to minimize exposure to hazardous vapor accumulations in the shelter once the air outside becomes less hazardous than the air inside the shelter. Temporary SIP, if properly executed, is considered to be an effective way to protect populations from hazardous chemical vapors, especially from high concentrations for short periods. This is supported by laboratory and field experiments. The need for timely termination of temporary SIP as protection from infiltrated vapors is an integral component of a temporary SIP strategy. It was from this premise that Argonne National Laboratory (ANL) was asked to develop methodologies for deciding when and how to terminate SIP. These methodologies, in turn, could be the basis for site-specific operational guidelines (e.g., decision matrix, decision-tree, or algorithm) for terminating SIP on each of the eight Army chemical stockpile storage sites, and in the off-post communities surrounding them. This project consists of two tasks. Task 1 was to collect and analyze existing literature that might be relevant to the termination of temporary SIP. This report is the product of Task 1. Task 2, which will begin on 2 February 2001, will use the results of the literature search as the baseline to investigate the concepts associated with temporary SIP, and to develop methodologies for termination of temporary SIP that can be incorporated in site-specific operational guidelines. It is understood that these methods will be consistent with Chemical Stockpile Emergency Preparedness Program (CSEPP) policy that ''the most important objective of the emergency preparedness and implementation process is the avoidance of fatalities to the maximum extent practicable, should an accidental release of chemical agent occur.'' It is also anticipated that these

    2012-01-01

    In DSP Architecture Design Essentials, authors Dejan Marković and Robert W. Brodersen cover a key subject for the successful realization of DSP algorithms for communications, multimedia, and healthcare applications. The book addresses the need for DSP architecture design that maps advanced DSP algorithms to hardware in the most power- and area-efficient way. The key feature of this text is a design methodology based on a high-level design model that leads to hardware implementation with minimum power and area. The methodology includes algorithm-level considerations such as automated word-length reduction and intrinsic data properties that can be leveraged to reduce hardware complexity. From a high-level data-flow graph model, an architecture exploration methodology based on linear programming is used to create an array of architectural solutions tailored to the underlying hardware technology. The book is supplemented with online material: bibliography, design examples, CAD tutorials and custom software.

    2013-01-01

    Real-time image and video processing applications require skilled architects, and recent trends in the hardware platform make the design and implementation of these applications increasingly complex. Many frameworks and libraries have been proposed or commercialized to simplify the design and tuning of real-time image processing applications. However, they tend to lack flexibility, because they are normally oriented toward particular types of applications, or they impose specific data processing models such as the pipeline. Other issues include large memory footprints, difficulty for reuse, and inefficient execution on multicore processors. We present a novel software architecture for time-constrained machine vision applications that addresses these issues. The architecture is divided into three layers. The platform abstraction layer provides a high-level application programming interface for the rest of the architecture. The messaging layer provides a message-passing interface based on a dynamic publish/subscribe pattern. A topic-based filtering in which messages are published to topics is used to route the messages from the publishers to the subscribers interested in a particular type of message. The application layer provides a repository for reusable application modules designed for machine vision applications. These modules, which include acquisition, visualization, communication, user interface, and data processing, take advantage of the power of well-known libraries such as OpenCV, Intel IPP, or CUDA. Finally, the proposed architecture is applied to a real machine vision application: a jam detector for steel pickling lines.

    Acne is a multifactorial inflammatory skin disease with high prevalence. In this work, the potential of 3D printing to produce flexible personalised-shape anti-acne drug (salicylic acid) loaded devices was demonstrated by two different 3D printing (3DP) technologies: Fused Deposition Modelling (FDM) and stereolithography (SLA). 3D scanning technology was used to obtain a 3D model of a nose adapted to the morphology of an individual. In FDM 3DP, commercially produced Flex EcoPLA™ (FPLA) and polycaprolactone (PCL) filaments were loaded with salicylic acid by hot melt extrusion (HME) (theoretical drug loading - 2% w/w) and used as feedstock material for 3D printing. Drug loading in the FPLA-salicylic acid and PCL-salicylic acid 3D printed patches was 0.4% w/w and 1.2% w/w respectively, indicating significant thermal degradation of drug during HME and 3D printing. Diffusion testing in Franz cells using a synthetic membrane revealed that the drug loaded printed samples released <187μg/cm(2) within 3h. FPLA-salicylic acid filament was successfully printed as a nose-shape mask by FDM 3DP, but the PCL-salicylic acid filament was not. In the SLA printing process, the drug was dissolved in different mixtures of poly(ethylene glycol) diacrylate (PEGDA) and poly(ethylene glycol) (PEG) that were solidified by the action of a laser beam. SLA printing led to 3D printed devices (nose-shape) with higher resolution and higher drug loading (1.9% w/w) than FDM, with no drug degradation. The results of drug diffusion tests revealed that drug diffusion was faster than with the FDM devices, 229 and 291μg/cm(2) within 3h for the two formulations evaluated. In this study, SLA printing was the more appropriate 3D printing technology to manufacture anti-acne devices with salicylic acid. The combination of 3D scanning and 3D printing has the potential to offer solutions to produce personalised drug loaded devices, adapted in shape and size to individual patients. PMID:27189134

    Synthetic oligonucleotides containing CpG motifs in specific sequence contexts have been shown to induce potent immune responses. We have evaluated mucosal administration of two immunostimulatory sequence (ISS)-containing phosphorothioate-stabilized oligonucleotides for antiherpetic efficacy in animal models. The ISS oligonucleotides, suspended in phosphate-buffered saline, were tested in mouse and guinea pig vaginal models of herpes simplex virus type 2 (HSV-2) infection. For comparison, groups of untreated, non-ISS oligonucleotide-treated, and acyclovir-treated animals also were monitored. The results indicated that vaginal epithelial application of ISS (up to 6 h after viral inoculation) with mice lethally challenged with HSV-2 delayed disease onset and reduced the number of animals that developed signs of disease (P = 0.003). ISS application significantly increased survival rates over those of controls (P = 0.0014). The ISS also impacted an established infection in the guinea pig model of HSV-2 disease. A single administration of ISS (21 days after viral inoculation) significantly reduced the frequency and severity of HSV-2 lesions compared to results with non-ISS oligonucleotide-treated and untreated guinea pigs (P < 0.01). HSV-2 is shed from the vaginal cavity of the guinea pig in the absence of lesions, similar to the case with humans. As an additional indication of ISS efficacy, the magnitude of viral shedding also was significantly reduced in ISS-treated animals (P < 0.001). These effects appeared to be immunologically mediated, since ISS had no direct effect on HSV-2 replication in vitro using standard plaque assays. These data suggest that ISS may be useful in the treatment and control of genital herpes in humans. PMID:12388699

    Despite advances in antimicrobial therapies, wound infection remains a global public health concern. We aimed to formulate and assess various nanoemulsions (NEs) for potential effectiveness as stable antimicrobial agents suitable for topic application. A total of 106 NEs were developed that varied with respect to nonionic and cationic surfactants. Stability testing demonstrated that the NEs tested are broadly stable, with 97/106 formulations passing 2-week stability tests. Two NEs, NB-201 and NB-402, were selected to test antimicrobial activity in a wound model in mice. Skin abrasion wounds were infected with Staphylococcus aureus followed by NE treatment. Infected skin was then evaluated by measuring colony forming units. NB-201 reduced median bacterial counts by 4 to 5 log compared to animals treated with saline, whereas NB-402 reduced bacterial counts by 2 to 3 log. Additional stability tests on NB-201 demonstrated that NB-201 is stable in the presence of human serum, and is stable for at least 6 months at 5°C, 25°C, and 40°C. Finally, in in vitro studies, NB-201 was found to be effective against S. aureus at a higher dilution than the commercially available silver sulfadiazine. Altogether these results demonstrate that NB-201 is a stable and effective topical antimicrobial for the treatment of S. aureus. PMID:27168582

    International Nuclear Information System (INIS)

    Highlights: • NiS@SiO2/graphene is prepared by a simple electrostatic attraction route. • NiS@SiO2/graphene presents nano-porous and hierarchical core-shell structure. • Superior cyclic stability and excellent rate capability are achieved. - Abstract: A well-designed hierarchical architecture NiS@SiO2/graphene is prepared through electrostatic self-assembly between (3-aminopropyl) triethoxysilane (APTES)-modified NiS and graphene in aqueous solutions at room temperature. The obtained composite possesses a unique structure with SiO2 ultrasmall nanoparticles (3–5 nm) derived from the pyrolysis of APTES homogeneously anchored on the surface of NiS nanoparticles (100 nm), forming NiS@SiO2 core-shell hybrid particles, which are well enveloped in graphene sheets. The SiO2 nanoparticles act as pillars to form open space between graphene sheets and NiS particles, which can buffer the volume change and afford easy electrolyte-wetting and fast lithium ion transport channels. The graphene sheets can not only significantly enhance the overall electrical conductivity of the NiS@SiO2/graphene electrode, but also serve as a blanket to wrap NiS particle and so as to avert its exfoliation from electrode due to large volume change during cycling. The prepared NiS@SiO2/graphene nanocomposite exhibits high reversible capacity (∼750 mAh g−1 for 100 cycles), remarkable cycling stability and impressive rate capability

    2013-01-01

    Full Text Available Apart from a brief overview of architectural communication viewed from the standpoint of theory of information and semiotics, this paper contains two forms of dualistically viewed architectural communication. The duality denotation/connotation (”primary” and ”secondary” architectural communication is one of semiotic postulates taken from Umberto Eco who viewed architectural communication as a semiotic phenomenon. In addition, architectural communication can be viewed as an intra and an extra activity of architecture where the overall activity of the edifice performed through its spatial manifestation may be understood as an act of communication. In that respect, the activity may be perceived as the ”behavior of architecture”, which corresponds to Lefebvre’s production of space.

  1. Detail in architecture: Between arts & crafts

    2016-06-01

    Architectural detail represents an important part of architecture. Not only can it be used as an identifier of a specific building but at the same time enhances the experience of the realized project. Within it lie the signs of a great architect and clues to understanding his or her way of thinking. It is therefore the central topic of a seminar offered to architecture students at the Brno University of Technology. During the course of the semester-long class the students acquaint themselves with atypical architectural details of domestic and international architects by learning to read them, understand them and subsequently draw them by creating architectural blueprints. In other words, by general analysis of a detail the students learn theoretical thinking of its architect who, depending on the nature of the design, had to incorporate a variety of techniques and crafts. Students apply this analytical part to their own architectural detail design. The methodology of the seminar consists of experiential learning by project management and is complemented by a series of lectures discussing a diversity of details as well as materials and technologies required to implement it. The architectural detail design is also part of students' bachelors thesis, therefore, the realistic nature of their blueprints can be verified in the production process of its physical counterpart. Based on their own documentation the students choose the most suitable manufacturing process whether it is supplied by a specific technology or a craftsman. Students actively participate in the production and correct their design proposals in real scale with the actual material. A student, as a future architect, stands somewhere between a client and an artisan, materializes his or her idea and adjusts the manufacturing process so that the final detail fulfills aesthetic consistency and is in harmony with its initial concept. One of the very important aspects of the design is its economic cost, an

  2. Orientalist Orientals: re-conceptualizing Ottoman architecture in the late Empire

    2015-12-01

    Full Text Available Review of Ahmet Ersoy, Architecture and the Late Ottoman Historical Imaginary: Reconfiguring the Architectural Past in a Modernizing Empire: Late Ottoman Empire’s concerted effort to forge a modern imperial identity to better position itself within the emerging world system was accompanied by a proto-nationalist desire for an authentic cultural past. In the field of art and architecture, the result was a new interest and patriotic pride in the Islamic artistic and architectural heritage of the Empire, along with an intense period of creative engagement with European artistic and scholarly discourses. The book offers a meticulously historicized account of what emerged as a major intellectual effort to construct a genealogy for Ottoman architecture, to make it intelligible in terms of Western architectural theory and above all, to recast it as a historically evolving style capable of revival in the modern world. In doing so, it critically engages with recent scholarly debates on modernity, historicism, romanticism, orientalism, nationalism, revivalism, cosmopolitanism, authenticity, eclecticism and hybridity among other topics. Taking issue with both the received “westernization paradigm” and its companion, the notorious “decline thesis” in terms of which the architecture of Ottoman Tanzimat has long been written, it gives us a more complex, more nuanced, more cosmopolitan and more ambivalent picture. As such, it makes a major contribution to Ottoman/ Turkish studies, to the historiography of Islamic architecture and to cross-cultural studies in general.

    Aslı ASLAN

    2007-06-01

    Full Text Available Music perception has a long and distinguished history as a topic of psychological research because music requires a mental activity in humans. As a complex human activity, music perception is naturally an area of interest especially to cognitive psychology. Cognitive studies suggest that listener’s experience of a particular musical sequence is driven and at the same time constrained by the sounds registered by auditory mechanisms but also processed by available mental resources. This assumption indicates that researchers must take into account certain inherent limitations and capabilities of the listener. The main purpose of this paper is to discuss possible cognitive processes underlying music perception. The steps taken towards this purpose will be describing the structure of music and discussing the way that this structure is perceived by human cognition.

  7. Human-competitive automatic topic indexing

    Topic indexing is the task of identifying the main topics covered by a document. These are useful for many purposes: as subject headings in libraries, as keywords in academic publications and as tags on the web. Knowing a document’s topics helps people judge its relevance quickly. However, assigning topics manually is labor intensive. This thesis shows how to generate them automatically in a way that competes with human performance. Three kinds of indexing are investigated: term assignment, a task commonly performed by librarians, who select topics from a controlled vocabulary; tagging, a popular activity of web users, who choose topics freely; and a new method of keyphrase extraction, where topics are equated to Wikipedia article names. A general two-stage algorithm is introduced that first selects candidate topics and then ranks them by significance based on their properties. These properties draw on statistical, semantic, domain-specific and encyclopedic knowledge. They are combined using a machine learn...

    2005-01-01

    Specialized as it might be, continuum theory is one of the most intriguing areas in mathematics. However, despite being popular journal fare, few books have thoroughly explored this interesting aspect of topology. In Topics on Continua, Sergio Macías, one of the field's leading scholars, presents four of his favorite continuum topics: inverse limits, Jones's set function T, homogenous continua, and n-fold hyperspaces, and in doing so, presents the most complete set of theorems and proofs ever contained in a single topology volume. Many of the results presented have previously appeared only in research papers, and some appear here for the first time. After building the requisite background and exploring the inverse limits of continua, the discussions focus on Professor Jones''s set function T and continua for which T is continuous. An introduction to topological groups and group actions lead to a proof of Effros''s Theorem, followed by a presentation of two decomposition theorems. The author then offers an...

  12. Computational methods for predicting the response of critical as-built infrastructure to dynamic loads (architectural surety)

    Coupled blast-structural computational simulations using supercomputer capabilities will significantly advance the understanding of how complex structures respond under dynamic loads caused by explosives and earthquakes, an understanding with application to the surety of both federal and nonfederal buildings. Simulation of the effects of explosives on structures is a challenge because the explosive response can best be simulated using Eulerian computational techniques and structural behavior is best modeled using Lagrangian methods. Due to the different methodologies of the two computational techniques and code architecture requirements, they are usually implemented in different computer programs. Explosive and structure modeling in two different codes make it difficult or next to impossible to do coupled explosive/structure interaction simulations. Sandia National Laboratories has developed two techniques for solving this problem. The first is called Smoothed Particle Hydrodynamics (SPH), a relatively new gridless method comparable to Eulerian, that is especially suited for treating liquids and gases such as those produced by an explosive. The SPH capability has been fully implemented into the transient dynamics finite element (Lagrangian) codes PRONTO-2D and -3D. A PRONTO-3D/SPH simulation of the effect of a blast on a protective-wall barrier is presented in this paper. The second technique employed at Sandia National Laboratories uses a relatively new code called ALEGRA which is an ALE (Arbitrary Lagrangian-Eulerian) wave code with specific emphasis on large deformation and shock propagation. ALEGRA is capable of solving many shock-wave physics problems but it is especially suited for modeling problems involving the interaction of decoupled explosives with structures.

  13. Kosmos = architecture

    Directory of Open Access Journals (Sweden)

    Tine Kurent

    2015-10-01

    Full Text Available The old Greek word "kosmos" means not only "cosmos", but also "the beautiful order", "the way of building", "building", "scenography", "mankind", and, in the time of the New Testament, also "pagans". The word "arhitekton", meaning first the "master of theatrical scenography", acquired the meaning of "builder", when the words "kosmos" and ~kosmetes" became pejorative. The fear that architecture was not considered one of the arts before Renaissance, since none of the Muses supervised the art of building, results from the misunderstanding of the word "kosmos". Urania was the Goddes of the activity implied in the verb "kosmein", meaning "to put in the beautiful order" - everything, from the universe to the man-made space, i. e. the architecture.

    A global transition towards a new energy architecture is under way, driven by countries' need to respond to the changing dynamics of economic growth, environmental sustainability and energy security. The World Economic Forum, in collaboration with Accenture, has created the New Energy Architecture Initiative to address and accelerate this transition. The Initiative supports the development of national strategies and policy frameworks as countries seek to achieve the combined goals of energy security and access, sustainability, and economic growth and development. The World Economic Forum has formed a partnership with the Ministry of Energy of Myanmar to help apply the Initiative's approach to this developing and resource-rich nation. The Asian Development Bank and the World Economic Forum's Project Adviser, Accenture, have collaborated with the Forum on this consultation process, and have been supported by relevant government, industry and civil society stakeholders. The consultation process aims to understand the nation's current energy architecture challenges and provide an overview of a path to a New Energy Architecture through a series of insights. These insights could form the basis for a long-term multistakeholder roadmap to build Myanmar's energy sector in a way that is secure and sustainable, and promotes economic growth as the country makes its democratic transition. While not all recommendations can be implemented in the near term, they do provide options for creating a prioritized roadmap for Myanmar's energy transition. This report is the culmination of a nine-month multistakeholder process investigating Myanmar's energy architecture. Over the course of many visits to the country, the team has conducted numerous interviews, multistakeholder workshops, and learning and data-gathering exercises to ensure a comprehensive range of information and views.

    Nonionic surfactants (caprylocaproyl macrogol-8 glycerides, octoxynol-12, polysorbate-20, and polyethylene glycol-40 hydrogenated castor oil) (47.03%, w/w), costabilizer (poloxamer 407) (12%-20%, w/w), oil (isopropyl myristate) (5.22%, w/w), water (q.s. ad 100%, w/w), and ibuprofen (5%, w/w) were used to develop oil-in-water microemulsions with Newtonian flow behavior, low viscosity (from 368 ± 38 to 916 ± 46 mPa s), and average droplet size from 14.79 ± 0.31 to 16.54 ± 0.75 nm. Ibuprofen in vitro release from the microemulsions was in accordance with zero-order kinetics (R0(2) > 0.99) for at least 12 h. The maximum drug release rate (3.55%h(-1) ) was from the microemulsion M3 comprising 16%, w/w of poloxamer 407. The release rate of ibuprofen from the reference hydrogel followed Higuchi kinetics (RH(2) > 0.99), and drug amount released after the 6th hour was negligible. In a rat model of inflammation, the microemulsion M3 was significantly more efficacious than the reference hydrogel in exerting antihyperalgesic effects in prophylactic topical treatment, whereas they were comparable in therapeutic treatment as well as in producing antiedematous effect in both protocols. No obvious skin irritation was observed in in vivo studies. The developed nonionic surfactants-based microemulsions containing the optimal concentration of poloxamer 407 could be promising carriers for sustained regional delivery of ibuprofen via topical administration.

  3. Topical or oral administration with an extract of Polypodium leucotomos prevents acute sunburn and psoralen-induced phototoxic reactions as well as depletion of Langerhans cells in human skin

    International Nuclear Information System (INIS)

    Sunburn, immune suppression, photo-aging, and skin cancers result from uncontrolled overexposure of human skin to solar ultraviolet radiation (UVR). Preventive measures, including photo-protection, are helpful and can be achieved by topical sun-screening agents. Polypodium leucotomos (PL) has been used for the treatment of inflammatory diseases and has shown some in vitro and in vivo immunomodulating properties. Its beneficial photo-protective effects in the treatment of vitiligo and its antioxidant properties encouraged us to evaluate in vivo the potentially useful photo-protective property of natural extract of PL after topical application or oral ingestion. Twenty-one healthy volunteers [either untreated or treated with oral psoralens (8-MOP or 5-MOP)] were enrolled in this study and exposed to solar radiation for evaluation of the following clinical parameters: immediate pigment darkening (IPD), minimal erythema dose (MED), minimal melanogenic dose (MMD), and minimal phototoxic dose (MPD) before and after topical or oral administration of PL. Immunohistochemical assessment of CD1a-expressing epidermal cells were also performed. PL was found to be photo-protective after topical application as well as oral administration. PL increased UV dose required for IPD (P<0.01), MED (P<0.001) and MPD (P<0.001). After oral administration of PL, MED increased 2.,8±0.59 times and MPD increased 2.75±0.5 and 6.8±1.3 times depending upon the type of psoralen used. Immunohistochemical study revealed photo-protection of Langherhans cells by oral as well as topical PL. The observed photo-protective activities of oral or topical PL reveal a new avenue in examining the potentially useful field of systemic photo-protection and suggests that PL can be used as adjunct treatment and can make photochemotherapy and phototherapy possibly safe and effective when the control of cutaneous phototoxicity to PUVA or UVB is a limiting factor in such photo-therapies.

    2006-01-01

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen. Discussion of the classical hydrogen...

  7. Ligand-binding specificity and promiscuity of the main lignocellulolytic enzyme families as revealed by active-site architecture analysis

    Science.gov (United States)

    Tian, Li; Liu, Shijia; Wang, Shuai; Wang, Lushan

    2016-01-01

    Biomass can be converted into sugars by a series of lignocellulolytic enzymes, which belong to the glycoside hydrolase (GH) families summarized in CAZy databases. Here, using a structural bioinformatics method, we analyzed the active site architecture of the main lignocellulolytic enzyme families. The aromatic amino acids Trp/Tyr and polar amino acids Glu/Asp/Asn/Gln/Arg occurred at higher frequencies in the active site architecture than in the whole enzyme structure. And the number of potential subsites was significantly different among different families. In the cellulase and xylanase families, the conserved amino acids in the active site architecture were mostly found at the −2 to +1 subsites, while in β-glucosidase they were mainly concentrated at the −1 subsite. Families with more conserved binding amino acid residues displayed strong selectivity for their ligands, while those with fewer conserved binding amino acid residues often exhibited promiscuity when recognizing ligands. Enzymes with different activities also tended to bind different hydroxyl oxygen atoms on the ligand. These results may help us to better understand the common and unique structural bases of enzyme-ligand recognition from different families and provide a theoretical basis for the functional evolution and rational design of major lignocellulolytic enzymes.

  12. Architectural Theory: A Construction Site

    Directory of Open Access Journals (Sweden)

    Ákos Moravánszky

    2014-07-01

    Full Text Available Around 1968 we saw the birth of a new architectural theory as the conjunction of architectural history and politically engaged architectural criticism. Not the aesthetics of architecture, but architecture itself in its structural relations with social life became the focus of attention. As a result of this development, it is no longer possible to study architectural history without a critical reflection on the method of the study itself and without a grade of interdisciplinarity. Traditional methods of historiography and iconography have been replaced by new approaches configured by psychoanalysis, deconstruction, cultural studies etc. Appropriation has become the proof of criticality both in architectural theory and in design; however, the understanding of the concepts and methods of other disciplines is basically metaphorical. The problem for a school of architecture lies not in the ‘criticality’ of the kind of architectural theory we described as emerging from the spirit of 1968, but in its discursive nature. The disciplinary specificity of architecture resists a discursive approach, and architectural students frequently question the usefulness of theory which undermines the notion of the ‘project’, without articulating a constructive proposal. Projectivity does not seem to provide an answer; its claim of performativity lacks the program to regain its organising power over contributions from other specialised disciplines and practices. Theory should focus on the terms of our discipline, which are so close to our ‘core beliefs’ regarding architecture that we usually take their meaning for granted. It would be wrong to see this focus of theory as a withdrawal into the realm of language. Indeed, after a period of theory alienating architects and the general public, it could now create a rhetoric to influence our understanding of our environment, which is itself organised on the level of language. The requirement that theory should

    2016-04-01

    Deltaic landforms and related stratigraphic architectures are frequently used as proxy for reconstruction of past continental or marine environmental evolutions. Indeed, in addition to autocyclic processes, emplacement of deltaic systems is primarily controlled by changes in sediment supply and relative sea-level (RSL). In our study, we investigated several proglacial deltaic complexes emplaced since the last deglaciation over more than 700 km along the St. Lawrence North Shore (Québec, Canada). Their geomorphic and stratigraphic records allowed us to infer the retreat pattern of the Laurentide Ice Sheet fronts. Field investigation of representative deltaic complexes revealed an archetypal morphostratigraphic evolution forced by the retreat of the ice margin in a context of falling RSL (glacio-isostatic rebound). The base of the stratigraphic successions consists of outwash fan deposits emplaced in the early deglaciation when ice margin stillstanded immediately beyond the depositional area. The middle part of the succession consists of proglacial delta deposits corresponding to the retreat of the ice margin in the hinterland. At that time, glaciogenic supplies allowed an active progradation preventing fluvial entrenchment in spite of the forced regressive context. The upper part of the succession consists of staged shoreline deposits reworking the rim of the proglacial deltas. These deposits mark the retreat of the ice margin from the drainage basin and the subsequent drop in glaciogenics. Important fluvial entrenchment occurred in the same time, though rates of RSL fall were reduced. We generalize this stratigraphic framework by using solely the landforms (from DEM, aerial photographs or satellite images) tied to deltaic complex developments along the St. Lawrence North Shore. This approach permits an integrated study at the scale of the whole basin even where no field data is available. Recognizing the three steps evidenced from the stratigraphic record ads

    In this paper, we report an ionic liquid-in-water (IL/w) microemulsion (ME) formulation which is able to solubilize etodolac (ETO), a poorly water soluble drug for topical delivery using BMIMPF6 (1-butyl-3-methylimidazolium hexafluorophosphate) as IL, Tween 80 as surfactant and ethanol as co-surfactant. The prepared ME was characterized for physicochemical parameters, subjected to ex-vivo permeation studies as well as in-vivo pharmacodynamic evaluation. The ex-vivo drug permeation studies through rat skin was performed using Franz-diffusion cell and the IL/w based ME showed maximum mean cumulative percent permeation of 99.030±0.921% in comparison to oil-in-water (o/w) ME (61.548±1.875%) and oily solution (48.830±2.488%) of ETO. In-vivo anti-arthritic and anti-inflammatory activities of the prepared formulations were evaluated using different rodent models and the results revealed that ETO loaded IL/w based ME was found to be more effective in controlling inflammation than oily solution, o/w ME and marketed formulation of ETO. Histopathological studies also demonstrated that IL/w based ME caused no anatomical and pathological changes in the skin. PMID:26456294

  2. Enterprise architecture evaluation using architecture framework and UML stereotypes

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available There is an increasing need for enterprise architecture in numerous organizations with complicated systems with various processes. Support for information technology, organizational units whose elements maintain complex relationships increases. Enterprise architecture is so effective that its non-use in organizations is regarded as their institutional inability in efficient information technology management. The enterprise architecture process generally consists of three phases including strategic programing of information technology, enterprise architecture programing and enterprise architecture implementation. Each phase must be implemented sequentially and one single flaw in each phase may result in a flaw in the whole architecture and, consequently, in extra costs and time. If a model is mapped for the issue and then it is evaluated before enterprise architecture implementation in the second phase, the possible flaws in implementation process are prevented. In this study, the processes of enterprise architecture are illustrated through UML diagrams, and the architecture is evaluated in programming phase through transforming the UML diagrams to Petri nets. The results indicate that the high costs of the implementation phase will be reduced.

    1993-01-01

    A framework for synthesizing software systems based on abstracting software system designs and the design process is described. The result of such an abstraction process is a generic architecture and the process knowledge for customizing the architecture. The customization process knowledge is used to assist a designer in customizing the architecture as opposed to completely automating the design of systems. Our approach using an implemented example of a generic tracking architecture which was customized in two different domains is illustrated. How the designs produced using KASE compare to the original designs of the two systems, and current work and plans for extending KASE to other application areas are described.

    The Simdarion Infranet (S1) is a term which is being used to dcscribc one element of a multidisciplinary distributed and distance computing initiative known as DisCom2 at Sandia National Laboratory (http ct al. 1998). The Simulation Intranet is an architecture for satisfying Sandia's long term goal of providing an end- to-end set of scrviccs for high fidelity full physics simu- lations in a high performance, distributed, and distance computing environment. The Intranet Architecture group was formed to apply current distributed object technologies to this problcm. For the hardware architec- tures and software models involved with the current simulation process, a CORBA-based architecture is best suited to meet Sandia's needs. This paper presents the initial desi-a and implementation of this Intranct based on a three-tier Network Computing Architecture(NCA). The major parts of the architecture include: the Web Cli- ent, the Business Objects, and Data Persistence.

    Full Text Available Topic models provide a convenient way to analyze large of unclassified text. A topic contains a cluster of words that frequently occur together. A topic modeling can connect words with similar meanings and distinguish between uses of words with multiple meanings. This paper provides two categories that can be under the field of topic modeling. First one discusses the area of methods of topic modeling, which has four methods that can be considerable under this category. These methods are Latent semantic analysis (LSA, Probabilistic latent semantic analysis (PLSA, Latent Dirichlet allocation (LDA, and Correlated topic model (CTM. The second category is called topic evolution models, which model topics by considering an important factor time. In the second category, different models are discussed, such as topic over time (TOT, dynamic topic models (DTM, multiscale topic tomography, dynamic topic correlation detection, detecting topic evolution in scientific literature, etc.

    Cosmeceutical antioxidants may protect the skin against oxidative injury, involved in the pathogenesis of many skin disorders. However, an unsuitable topical delivery system with compromising safety profile can affect the efficacy of an antioxidant active. This study investigated the antioxidant potential of lactobionic acid (LA), a newer cosmeceutical active, per se (in solution) and incorporated into natural alkyl polyglucoside (APG) emulsifier-based system using 1,1-diphenyl-2-picrylhydrazyl free radical scavenging and lipid peroxidation inhibition assays. The α-tocopherol was used as a reference compound. The physical stability (using rheology, polarization microscopy, pH and conductivity measurements) of an Alkyl glucoside-based emulsion was evaluated with and without the active (LA); colloidal structure was assessed using polarization and transmission electron microscopy, rheology, thermal and texture analysis. Additionally, the safety profile and moisturizing potential were investigated using the methods of skin bioengineering. Good physical stability and applicative characteristics were obtained although LA strongly influenced the colloidal structure of the vehicle. LA per se and in APG-based emulsion showed satisfying antioxidant activity that promotes it as mild multifunctional cosmeceutical efficient in the treatment and prevention of the photoaged skin. Employed assays were shown as suitable for the antioxidant activity evaluation of LA in APG-based emulsions, but not for α-tocopherol in the same vehicle. PMID:22691034

  9. Maps on the basis of the Arts & Humanities Citation Index: The journals Leonardo and Art Journal versus "Digital Humanities" as a topic

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    The possibilities of using the Arts & Humanities Citation Index (A&HCI) for journal mapping have not been sufficiently recognized because of the absence of a Journal Citations Report (JCR) for this database. A quasi-JCR for the A&HCI (2008) was constructed from the data contained in the Web-of-Science and is used for the evaluation of two journals as examples: Leonardo and Art Journal. The maps on the basis of the aggregated journal-journal citations within this domain can be compared with maps including references to journals in the Science Citation Index and Social Science Citation Index. Art journals are cited by (social) science journals more than by other art journals, but these journals draw upon one another in terms of their own references. This cultural impact in terms of being cited is not found when documents with a topic such as "digital humanities" are analyzed. This community of practice functions more as an intellectual organizer than a journal.

On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

  15. Embedded instrumentation systems architecture

    Visnevski, Nikita A.

    2007-04-01

    This paper describes the operational concept of the Embedded Instrumentation Systems Architecture (EISA) that is being developed for Test and Evaluation (T&E) applications. The architecture addresses such future T&E requirements as interoperability, flexibility, and non-intrusiveness. These are the ultimate requirements that support continuous T&E objectives. In this paper, we demonstrate that these objectives can be met by decoupling the Embedded Instrumentation (EI) system into an on-board and an off-board component. An on-board component is responsible for sampling, pre-processing, buffering, and transmitting data to the off-board component. The latter is responsible for aggregating, post-processing, and storing test data as well as providing access to the data via a clearly defined interface including such aspects as security, user authentication and access control. The power of the EISA architecture approach is in its inherent ability to support virtual instrumentation as well as enabling interoperability with such important T&E systems as Integrated Network-Enhanced Telemetry (iNET), Test and Training Enabling Architecture (TENA) and other relevant Department of Defense initiatives.

    Twitter is an extremely high volume platform for user generated contributions regarding any topic. The wealth of content created at real-time in massive quantities calls for automated approaches to identify the topics of the contributions. Such topics can be utilized in numerous ways, such as public opinion mining, marketing, entertainment, and disaster management. Towards this end, approaches to relate single or partial posts to knowledge base items have been proposed. However, in microblogging systems like Twitter, topics emerge from the culmination of a large number of contributions. Therefore, identifying topics based on collections of posts, where individual posts contribute to some aspect of the greater topic is necessary. Models, such as Latent Dirichlet Allocation (LDA), propose algorithms for relating collections of posts to sets of keywords that represent underlying topics. In these approaches, figuring out what the specific topic(s) the keyword sets represent remains as a separate task. Another issue in topic detection is the scope, which is often limited to specific domain, such as health. This work proposes an approach for identifying domain-independent specific topics related to sets of posts. In this approach, individual posts are processed and then aggregated to identify key tokens, which are then mapped to specific topics. Wikipedia article titles are selected to represent topics, since they are up to date, user-generated, sophisticated articles that span topics of human interest. This paper describes the proposed approach, a prototype implementation, and a case study based on data gathered during the heavily contributed periods corresponding to the four US election debates in 2012. The manually evaluated results (0.96 precision) and other observations from the study are discussed in detail. PMID:26991442

  5. Fabrication of porous BaSnO3 hollow architectures using BaCO3-SnO2 core-shell nanorods as precursors

    International Nuclear Information System (INIS)

    We present a strategy to synthesize porous BaSnO3 hollow architectures with that were 150-300 nm in diameter and 1.5-5 μm in length using precursor of BaCO3-SnO2 nanorods prepared by hydrothermal treatment. BaCO3-SnO2 nanorods, consisting of a BaCO3 core and a SnO2 shell, could be used effectively for the solid-state synthesis of polycrystalline BaSnO3 powder at 800 deg. C (lower than convention for BaCO3 and SnO2 mixtures). The core/shell structure of the precursor could play a role as a structural directing template for preparing BaSnO3 hollow architectures during the calcination process. The X-ray diffractometer (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM) are employed to characterize the structures and morphologies. When applied to DSSC, the porous BaSnO3 hollow architectures exhibit distinct photovoltaic effect.

  9. Minimizing the Risk of Architectural Decay by using Architecture-Centric Evolution Process

    CERN Document Server

    Farid, Humaira; Iqbal, M Aqeel

    2011-01-01

    Software systems endure many noteworthy changes throughout their life-cycle in order to follow the evolution of the problem domains. Generally, the software system architecture cannot follow the rapid evolution of a problem domain which results in the discrepancies between the implemented and designed architecture. Software architecture illustrates a system's structure and global properties and consequently determines not only how the system should be constructed but also leads its evolution. Architecture plays an important role to ensure that a system satisfies its business and mission goals during implementation and evolution. However, the capabilities of the designed architecture may possibly be lost when the implementation does not conform to the designed architecture. Such a loss of consistency causes the risk of architectural decay. The architectural decay can be avoided if architectural changes are made as early as possible. The paper presents the Process Model for Architecture-Centric Evolution which ...

  10. Topical treatment of melasma

    Full Text Available Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma.

    Full Text Available Corticosteroids, one of the most widely prescribed topical drugs, have been used for about six decades till date. However, rampant misuse and abuse down the years has given the drug a bad name. Topical steroid abuse may lead to two major problems which lie at the opposing ends of the psychosomatic spectrum. Topical steroid addiction, a phenomenon that came to be recognized about a decade after the introduction of the molecule is manifested as psychological distress and rebound phenomenon on stoppage of the drug. The rebound phenomenon, which can affect various parts of the body particularly the face and the genitalia has been reported by various names in the literature. TC phobia which lies at the opposite end of the psychiatric spectrum of steroid abuse has been reported particularly among parents of atopic children. Management of both conditions is difficult and frustrating. Psychological counseling and support can be of immense help in both the conditions.

    Full Text Available With changing times various newer topical agents are introduced in the field of dermatology. Tacrolimus and pimecrolimus are immunisuppressants, which are effective topically and are tried in the management of atopic dermatitis as well as other disorders including allergic contact dermatitis, atrophic lichen planus, pyoderma gangrenosum. Imiquimod, an immune response modifier, is presently in use for genital warts but has potentials as anti- tumour agent and in various other dermatological conditions when used topically. Tazarotene is a newer addition to the list of topical reginoids, which is effective in psoriasis and has better effect in combination with calcipotriene, phototherapy and topical costicosteroids. Tazarotene and adapelene are also effective in inflammatory acne. Calcipotriol, a vitamin D analogue has been introduced as a topical agent in the treatment of psoriasis. Steroid components are also developed recently which will be devoid of the side effects but having adequate anti-inflammatory effect. Topical photodynamic therapy has also a wide range of use in dermatology. Newer topical agents including cidofovir, capsaicin, topical sensitizers, topical antifungal agents for onychomycosis are also of use in clinical practice. Other promising developments include skin substitutes and growth factors for wound care.

    Full Text Available The aesthetic aspects of the existence of architectural space is closely related to its scene. The scene of architectural objects and all the architectural space allow enables the existence and active external expression of its non-use component, abstract spiritual meanings, ideas and images. The purpose of this study is the aesthetic and philosophical analysis of the shape of architectural space. The research problem is the search for the relationship between the scene of the architectural space and its existence as the outer presentation of spiritual meanings. Under the scene of architectural space we mean to its expressive exterior shell that is available to the perception of the senses. Architectural space is a certain visibility. This space by which can act spiritual aspects of the human content of architecture. The architectural scene is not only the look of the architectural object or element of architectural space, but and architectural appearance (face of the people. The architectural scene is built in accordance with the needs of the inner world of man and contains the image of the person in the material form. It is also the external scene of the architectural environment for human been and appearance of the individual life. Therefore, the scene of architecture is concrete space. National, social, cultural identity finds expression through the scene of its architectural space.

    The overall architecture of the nervous system, especially the CNS, is remarkable. The anatomy of the nervous system is constituted not only by macroscopic and microscopy identifiable regions and neuronal cell types, but also by protein complexes whose identification and localization require sophisticated techniques. G-protein-coupled receptors (GPCRs) constitute an example of proteins that are the key factors in the framework needed to sustain brain and nerve structure and function. The versatility underlying nervous system anatomy takes advantage of a recently discovered feature of GPCRs, the possibility to form heteromers that, placed at specific neuronal subsets and at specific locations (pre-, post-, or peri-synaptic), contribute to attain unique neural functions.

    1984-05-01

    This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references.

    2014-01-01

    A certain curious feature of random objects, introduced by the author as “super concentration,” and two related topics, “chaos” and “multiple valleys,” are highlighted in this book. Although super concentration has established itself as a recognized feature in a number of areas of probability theory in the last twenty years (under a variety of names), the author was the first to discover and explore its connections with chaos and multiple valleys. He achieves a substantial degree of simplification and clarity in the presentation of these findings by using the spectral approach. Understanding the fluctuations of random objects is one of the major goals of probability theory and a whole subfield of probability and analysis, called concentration of measure, is devoted to understanding these fluctuations. This subfield offers a range of tools for computing upper bounds on the orders of fluctuations of very complicated random variables. Usually, concentration of measure is useful when more direct prob...

    Full Text Available “Cloud” computing a comparatively term, stands on decades of research & analysis in virtualization, analytical distributed computing, utility computing, and more recently computer networking, web technology and software services. Cloud computing represents a shift away from computing as a product that is purchased, to computing as a service that is delivered to consumers over the internet from large-scale data centers – or “clouds”. Whilst cloud computing is obtaining growing popularity in the IT industry, academic appeared to be lagging behind the developments in this field. It also implies a service oriented designed architecture, reduced information technology overhead for the end-user, good flexibility, reduced total cost of private ownership, on-demand services and many other things.

  9. Parent's alcoholism severity and family topic avoidance about alcohol as predictors of perceived stigma among adult children of alcoholics: Implications for emotional and psychological resilience.

    Science.gov (United States)

    Haverfield, Marie C; Theiss, Jennifer A

    2016-01-01

    Alcoholism is a highly stigmatized condition, with both alcohol-dependent individuals and family members of the afflicted experiencing stigmatization. This study examined the severity of a parent's alcoholism and family topic avoidance about alcohol as two factors that are associated with family members' perceptions of stigma. Three dimensions of stigma were considered: discrimination stigma, disclosure stigma, and positive aspect stigma. In addition, this study assessed associations between perceived stigmatization and individuals' experiences of depressive symptoms, self-esteem, and resilience. Adult children of alcoholics (N = 622) were surveyed about family conditions, perceived stigma, and their emotional and psychological well-being. Regression analyses revealed that the severity of a parent's alcoholism predicted all three types of stigma for females, but not for males. In addition, family topic avoidance about alcohol predicted all types of stigma for males and discrimination stigma and positive aspect stigma for females. With few exceptions, the three types of stigma predicted depressive symptoms, self-esteem, and resilience for both male and female adult children of alcoholics. The results are discussed in terms of their implications for promoting a family environment that mitigates stigma and encourages emotional and psychological well-being. In 2012, approximately 3.3 million deaths worldwide were due to the harmful use of alcohol (World Health Organization [WHO], 2014). Individuals who abuse alcohol are susceptible to a variety of negative health outcomes (Rehm et al., 2009) and display inappropriate social behaviors (Klingemann, 2001; Schomerus et al., 2011a). General societal perceptions tend to characterize alcohol-dependent individuals as irresponsible and lacking in self-control (Schomerus et al., 2011b). Research in the United Kingdom found that 54% of the population believes alcohol-dependent individuals are personally to blame for their own

    2003-01-01

    New and improved drug delivery systems are the important subject of much scientific research. The development of formulations that increase skin oxygenation and of methods for measuring oxygen levels in skin are important for dealing with healing processes affected by the level of oxygen. We have used EPR oximetry in vivo to compare the influence of liposomal formulations of different size and composition with that of hydrogel with respect to the action of the entrapped benzyl nicotinate (BN). Following the topical application of BN onto the skin of mice, pO2 increase was measured by low-frequency EPR as a function of time. The effect of BN was evaluated by 3 different parameters: lag-time, time needed for maximum pO2 increase, and overall effectiveness expressed by the area under the response-time curve. An increase in skin oxygenation was observed after BN application. The results show that the effect of BN incorporated in liposomes is achieved more rapidly than the effect from hydrophilic gel. The composition of the liposomes significantly affects the time at which BN starts to act and, to a lesser extent, the maximum increase of pO2 in skin and the effectiveness of BN action. However, the size of the liposomes influences both the effectiveness of BN action and the time at which BN starts to act. After repeated application of liposomes, the pO2 baseline increased and the response of the skin tissue was faster. Our results demonstrate that EPR oximetry is a useful method for evaluating oxygen changes after drug application and for following the time course of their action. PMID:12713274
