    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.

  2. Topical peptides as cosmeceuticals

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Peptides are known to have diverse biological roles, most prominently as signaling/regulatory molecules in a broad variety of physiological processes including defense, immunity, stress, growth, homeostasis and reproduction. These aspects have been used in the field of dermatology and cosmetology to produce short, stable and synthetic peptides for extracellular matrix synthesis, pigmentation, innate immunity and inflammation. The evolution of peptides over the century, which started with the discovery of penicillin, has now extended to their usage as cosmeceuticals in recent years. Cosmeceutical peptides may act as signal modulators of the extracellular matrix component, as structural peptides, carrier peptides and neurotransmitter function modulators. Transdermal delivery of peptides can be made more effective by penetration enhancers, chemical modification or encapsulation of peptides. The advantages of using peptides as cosmeceuticals include their involvement in many physiological functions of the skin, their selectivity, their lack of immunogenicity and absence of premarket regulatory requirements for their use. However, there are disadvantages: clinical evidence for efficacy is often weak, absorption may be poor due to low lipophilicity, high molecular weight and binding to other ingredients, and prices can be quite high.

    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.

    2015-11-01

    Full Text Available The point of departure of the architectural project has to stem from the combination of inner and outer journeys in between the real or imagined limits. The pressing challenge is to destabilize the neat division of architecture into separate bodies of knowledge and pose the architect’s mode of action on the threshold between the concrete and the universal. Architecture is a lens, an instrument one looks through to bring new perspectives into focus, enabling the transformation of experience from a magnified self-concentrated space to a wide horizon. Architecture narrates relations between spaces and examines its validity through signifying practices of design. Design for itself becomes the language of the current, of the immediate fashion. Architecture can fulfill peoples’ dreams and miraculously can provide them tools to invent new ones: Curiosity is the first motive to act.

  7. On minimalism in architecture - space as experience

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Architecture has to be experienced to be understood. The complexity of the experience is seen through a better understanding of the relationship between objectivity (architecture and subjectivity (our life. Being physically, emotionally and psychologically aware of the space we occupy is an experience that could be described as being present, which is a sensation that is personal and difficult to explicitly describe. Research into experience through perception and emotion positions architecture within scientific fields, in particular psychological disciplines. Relying on the standpoints of Immanuel Kant, the paper considers the juxtaposition between (minimalism in architecture and philosophy on the topic of experience. Starting from the basic aspects of perception and representation of the world around us, a thesis is presented in which the notions of silence and light as experienced in minimalism (in architecture are considered as adequate counterparts to Kant’s factors of experience - the awareness of the objective order of events and the impossibility to perceive time itself. Through a case study we verify the starting hypothesis on minimalism (in architecture whereby space becomes an experience of how the world touches us.

  9. Network architecture as internet governance

    Directory of Open Access Journals (Sweden)

    Francesca Musiani

    2013-10-01

    Full Text Available The architecture of a networked system is its underlying technical and logical structure, including transmission equipment, communication protocols, infrastructure, and connectivity between its components or nodes. This article introduces the idea of network architecture as internet governance, and more specifically, it outlines the dialectic between centralised and distributed architectures, institutions and practices, and how they mutually affect each other. The article argues that network architecture is internet governance in the sense that, by changing the design of the networks subtending internet-based services and the global internet itself, its politics are affected – the balance of rights between users and providers, the capacity of online communities to engage in open and direct interaction, the fair competition between actors of the internet market.

  11. Topical and peripheral ketamine as an analgesic.

    Science.gov (United States)

    Sawynok, Jana

    2014-07-01

    Ketamine, in subanesthetic doses, produces systemic analgesia in chronic pain settings, an action largely attributed to block of N-methyl-D-aspartate receptors in the spinal cord and inhibition of central sensitization processes. N-methyl-D-aspartate receptors also are located peripherally on sensory afferent nerve endings, and this provided the initial impetus for exploring peripheral applications of ketamine. Ketamine also produces several other pharmacological actions (block of ion channels and receptors, modulation of transporters, anti-inflammatory effects), and while these may require higher concentrations, after topical (e.g., as gels, creams) and peripheral application (e.g., localized injections), local tissue concentrations are higher than those after systemic administration and can engage lower affinity mechanisms. Peripheral administration of ketamine by localized injection produced some alterations in sensory thresholds in experimental trials in volunteers and in complex regional pain syndrome subjects in experimental settings, but many variables were unaltered. There are several case reports of analgesia after topical application of ketamine given alone in neuropathic pain, but controlled trials have not confirmed such effects. A combination of topical ketamine with several other agents produced pain relief in case, and case series, reports with response rates of 40% to 75% in retrospective analyses. In controlled trials of neuropathic pain with topical ketamine combinations, there were improvements in some outcomes, but optimal dosing and drug combinations were not clear. Given orally (as a gargle, throat swab, localized peritonsillar injections), ketamine produced significant oral/throat analgesia in controlled trials in postoperative settings. Topical analgesics are likely more effective in particular conditions (patient factors, disease factors), and future trials of topical ketamine should include a consideration of factors that could predispose

  13. Deconstruction as concept of architectural practice

    Maksimović Milan

    2013-01-01

    Full Text Available This paper inquires into the relationship between philosophical concept of deconstruction and its practical application in the interpretation of the concept of architectural creativity. Deconstruction is not only understood as a formal metaphor, but as a critical process that examines common approaches to architectural design and approach to the treatment of architectural space. Through a comparison with philosophy, this procedure highlights the architectural approach seen as a decomposition of normal and usual way of thinking about architecture and therefore associated treatment of the architectural concept in creative practice. By case study method, analyzed the formal concept of building 'Zepter Palace' in Belgrade, which is interpreted as a deconstruction of the concept of architectural practice. In this example, in comparison with the well-known interpretation of deconstruction on project of La Villette Park in Paris, derived a key contribution of the philosophical deconstruction to the concept of architectural practice - approach that establishes and promotes a method for creating and widening of architectural diversity, seen as a new space sensuality of aesthetic experience of space.

  14. Architecture as an emerging Agent of Change

    Directory of Open Access Journals (Sweden)

    Mason White

    2015-11-01

    Full Text Available The most pressing challenge to architecture today is to be more relevant as an agent of change. There is much work needed in making architecture socially and culturally relevant. The value of architecture needs to be better understood by a wider public. As the big city increasingly becomes the subject of interest for advancing architecture’s relevance, the mid-tier cities, countryside and even remote locales are overlooked. Today the term “Design” is often confused with Style. Understanding design as style skips the methods and processes of conceptualization while architecture offers a more complex understanding of design that expands beyond author’s will. For the discipline to be alive and evolve, it is necessary that there be agitation and scepticism cultivated in school.

  15. Use of topical antibiotics as prophylaxis in clean dermatologic procedures.

    Topical antibiotics are not indicated for routine postoperative care in clean dermatologic procedures, but may be widely used. We sought to describe topical antibiotic use in clean dermatologic surgical procedures in the United States. The 1993 to 2007 National Ambulatory Medical Care Survey database was queried for visits in which clean dermatologic surgery was performed. We analyzed provider specialty, use of topical antibiotics, and associated diagnoses. Use of topical antibiotic over time was analyzed by linear regression. An estimated 212 million clean dermatologic procedures were performed between 1993 and 2007; topical antibiotics were reported in approximately 10.6 million (5.0%) procedures. Dermatologists were responsible for 63.3% of dermatologic surgery procedures and reported use of topical antibiotic prophylaxis in 8.0 million (6.0%). Dermatologists were more likely to use topical antibiotic prophylaxis than nondermatologists (6.0% vs 3.5%). Use of topical antibiotic prophylaxis decreased over time. Data were limited to outpatient procedures. The assumption was made that when topical antibiotics were documented at procedure visits they were being used as prophylaxis. Topical antibiotics continue to be used as prophylaxis in clean dermatologic procedures, despite being ineffective for this purpose and posing a risk to patients. Although topical antibiotic use is decreasing, prophylactic use should be eliminated. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

  1. Sustainable Architecture in the Context of Education: Reponses of Primary School Teachers on the Topical Subject

    Directory of Open Access Journals (Sweden)

    Cencič Majda

    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 Today, the new trend that companies are following is to digitalize all data they have in order to reduce costs with physical space and better handle data volume. The new era, the era of bundling data sources and huge volumes of data continues this decade also. In all industries, companies are starting to understand and appreciate the value of data, the value that these volumes of data can produce. Companies are collecting huge volumes of data but not always the actual solution for business intelligence (BI can handle these volumes. To obtain information, those volumes of data are analyzed with extract-transform-load (ETL software solutions. Companies, in the current economic context, are finding hard to invest in improvements of BI process including in ETL process. In this paper I will demonstrate why this kind of investment is necessary and also I will demonstrate that ETL process must be included in BI and big data architectures. In the following pages I will refer to business architectures as BI and big data architectures.

  4. Topicality as War News Value: A Pragma – Linguistic Study

    Directory of Open Access Journals (Sweden)

    Fareed Hameed Al-Hindawi

    2017-07-01

    Full Text Available This paper discusses one of the criteria of war news values in printed media. The current study concerns itself with only Topicality as the target of scrutiny. It explores this value through the application of a model of analysis based on a pragma-linguistic approach. The analysis is intended to achieve the following aims: first, bringing topicality as one criterion of news values to the attention of pragmatists; second, introducing an analytical framework which is hoped to be useful for pragmatists to analyze news values, and to be available in their hands for further development. This framework aims at explicitly revealing the linguistic as well as the pragmatic properties of the war news texts as far as topicality is concerned. In relation to the aims of the study and owing to the fact that people are eager to understand what is going on, it is hypothesized that topicality comes into viewable interaction between grammar and pragmatics. The findings of the data analysis indicate how topicality is transferred to the receiver of the message and how it shapes news reporting.

    2016-07-01

    Previous studies have demonstrated the antiherpes activity of pentyl gallate (PG), suggesting that it could be a promising candidate for the topical treatment of human herpes labialis. PG low aqueous solubility represents a major drawback to its incorporation in topical dosage forms. Hence, the feasibility of incorporating PG into nanoemulsions, the ability to penetrate the skin, to inhibit herpes simplex virus (HSV)-1 replication, and to cause dermal sensitization or toxicity were evaluated. Oil/water nanoemulsions containing 0.5% PG were prepared by spontaneous emulsification. The in vitro PG distribution into porcine ear skin after topical application of nanoemulsions was assessed, and the in vitro antiviral activity against HSV-1 replication was evaluated. Acute dermal toxicity and risk of dermal sensitization were evaluated in rat model. Nanoemulsions presented nanometric particle size (from 124.8 to 143.7 nm), high zeta potential (from -50.1 to -66.1 mV), loading efficiency above 99%, and adequate stability during 12 months. All formulations presented anti-HSV-1 activity. PG was able to reach deeper into the dermis more efficiently from the nanoemulsion F4. This formulation as well as PG were considered safe for topical use. Nanoemulsions seem to be a safe and effective approach for topically delivering PG in the treatment of human herpes labialis infection.

    2004-01-01

    We reported on the case of a patient who developed a cutaneous eruption in a photoexposed area 1 week after a continous topical treatment with dexketoprofen (Enangel). Photopatch tests were positive for dexketoprofen, ketoprofen and piketoprofen and patch test was positive for piketoprofen. Control photopatch testing with dexketoprofen in 15 healthy volunteers was negative. Dexketoprofen, ketoprofen and piketoprofen are non-steroidal anti-inflamatory drugs (arylpropionic acid derivatives) often used as topical anti-inflammatory agents. It appears that the benzophenone moiety of their chemical structure is the cause of their photosensitivity and cross-photoreaction.

    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.

    Ebrahimi, Bahareh; Naeini, Farahnaz Fatemi

    2014-01-01

    Background: In recent times, tranexamic acid (TA) is claimed to have whitening effects especially for ultraviolet-induced hyperpigmentation including melasma. The aim of our study was to evaluate the efficacy and safety of topical solution of TA and compare it with combined solution of hydroquinone and dexamethasone as the gold standard treatment of melasma in Iranian women. Materials and Methods: This was a double-blind split-face trial of 12 weeks which was conducted in Isfahan, Iran. Fifty Iranian melasma patients applied topical solution of 3% TA on one side of the face, and topical solution of 3% hydroquinone + 0.01% dexamethasone on the other side two times a day. The Melasma Area and Severity Index (MASI) and the side effects were evaluated at baseline and every 4 weeks before and after photographs to be compared by a dermatologist were taken. The patient satisfaction was documented at week 12. Results: A repeated measurement analysis was used to evaluate the changes in the MASI score before and after treatments. A significant decreasing trend was observed in the MASI score of both groups with no significant difference between them during the study (P < 0.05). No differences were seen in patients’ and investigator's satisfaction of melasma improvement between two groups (P < 0.05). However, the side effects of hydroquinone + dexamethasone were significantly prominent compared with TA (P = 0.01). Conclusion: This study's results introduce the topical TA as an effective and safe medication for the treatment of melasma. PMID:25422661

    Full Text Available More and more, existing buildings – and particularly historic buildings – are becoming part of the daily business of every architect. Planning and designing in the field of architectural heritage requires not only knowledge of contemporary building techniques, design processes and national and international guidelines, but also a deep understanding of architectural heritage, its evolution and genesis, the building techniques that have been applied, materials used, traditions, etc. In many cases, it is indispensable to perform a detailed building survey and building research to achieve an adequate design concept. The Department of History of Architecture and Building Archaeology of TU Wien has an extensive tradition of building research and over the course of the past 10 years, has developed a teaching workflow to introduce architectural students to building archaeology und surveying methods for building research. A sophisticated, temporally interwoven combination of courses and lectures on different topics related to building archaeology and surveying rapidly gives the architectural students the right tools for this important but often neglected task.

    One of the most effective methods to achieve a sustainable change of our momentary existing power supply system to a system mainly based on renewable energy conversion is the education of our children. For this purpose the compulsory school subject mathematics appears to be suitable. In order to promote renewable energy issues in mathematics classrooms, the authors have developed a special didactical concept to open this field for students, as well as for their teachers. The aim of this paper is to present firstly an overview of our concept and secondly examples of problems to the special topic of solar thermal energy, developed on the basis of our concept. (orig.)

    associations were found between starting using fluoride toothpaste/toothbrushing before or after the age of 24 months and fluorosis (data from observational studies). From the RCTs, use of higher level of fluoride was associated with an increased risk of fluorosis. No significant association between the frequency of toothbrushing or the amount of fluoride toothpaste used and fluorosis was found. There should be a balanced consideration between the benefits of topical fluorides in caries prevention and the risk of the development of fluorosis. Most of the available evidence focuses on mild fluorosis. There is weak unreliable evidence that starting the use of fluoride toothpaste in children under 12 months of age may be associated with an increased risk of fluorosis. The evidence for its use between the age of 12 and 24 months is equivocal. If the risk of fluorosis is of concern, the fluoride level of toothpaste for young children (under 6 years of age) is recommended to be lower than 1000 parts per million (ppm).More evidence with low risk of bias is needed. Future trials assessing the effectiveness of different types of topical fluorides (including toothpastes, gels, varnishes and mouthrinses) or different concentrations or both should ensure that they include an adequate follow-up period in order to collect data on potential fluorosis. As it is unethical to propose RCTs to assess fluorosis itself, it is acknowledged that further observational studies will be undertaken in this area. However, attention needs to be given to the choice of study design, bearing in mind that prospective, controlled studies will be less susceptible to bias than retrospective and/or uncontrolled studies.

    With the rising price of energy and increasing concerns over the environment, ways of creating sustainable architecture are getting more and more attention. Buildings in Iran are confronted with a variety of weather conditions and specific measures have been taken to adapt traditional architecture to the environment and minimize energy consumption. The aim of this paper is to present the different materials and solutions used in traditional Iranian architecture. This review showed that sustainable architecture in an arid climate can be realised by the use of soil as a building insulator. Other methods consist in orienting the building in such a way as to absorb sunlight, using wind towers and wind scope, dividing a yard in such a way that different areas are used, depending on the season, and building underground spaces to provide comfortable conditions. This paper highlighted several historical methods and materials which can be used to bring about sustainable architecture in an arid climate.

    Full Text Available With the technological advances in biomedical sciences and the better understanding of how the immune system works, new immunisation strategies and vaccine delivery options, such sprays, patches, and edible formulations have been developed. Needle-free delivery of vaccines has become a global priority. Transcutaneous immunisation (TCI, topical application of vaccine antigens to the skin, can elicit systemic antibody and T-cell responses, suggesting that this new technique may provide a means for vaccination without needles. TCI requires the use of an adjuvant such as cholera toxin added to a vaccine antigen, such as diphtheria toxoid, to induce antibodies to diphtheria toxoid. The adjuvant and antigen are thought to target Langerhans cells, potent antigen-presenting cells found in the superficial layers of the skin. TCI appears to be a highly practical technique for delivery of vaccines that provides unique access to the immune system.

    Grupe, G

    1990-06-01

    Human population history is firmly connected with temporal and regional changes of the environment. Whether natural or anthropogene, alteration of environmental features lead to changes of human life-style and to the development of adaptive strategies. The demand of resources for his subsistence has led man to diverse impacts on his environment since ever. Thus, environmental history is a scientific topic for anthropologists. The research potential of trace element studies of excavated human skeletons for the reconstruction of natural and socio-cultural environments as well as for distribution patterns of hazardous substances is outlined for the European Middle Ages. The scientific value of unravelling past man/environment-interrelationships for both the historical and applied sciences and the place of any "chemical anthropology" within this context is discussed.

  20. 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.

    Painter, Sally L; Hildebrand, Göran Darius

    2016-01-01

    The treatment of infantile hemangiomas changed from the use of oral corticosteroids to oral propranolol on the serendipitous discovery of propanolol's clinical effectiveness in 2008. Since then, clinicians have begun to use topical beta blockers--in particular, timolol maleate 0.5% gel forming solution--with good effect. Topical beta blockers are now used for lesions with both deep and superficial components and those that are amblyogenic. When initiated in the proliferative phase of the lesion, the effectiveness of the treatment can be seen within days. There is no consensus on dosing, treatment bioavailability, or clinical assessment of lesions, but these are topics for future research.

    Full Text Available Materials, as an instrument for author's report of his ideas and puts them into the space and time, is a recurring theme of architecture, from the time of Vitruvius triad (firmitas. In minimalism, materials shape space and express its essence, which is the irreducible minimum. The approach in this paper is methodologically defined by architecture domain that is art within it, therefore what the visual means are materials, with the aspiration to discover meaning in what we see. The principles of visual perception are primarily active in the field of law perceptions reached by the psychology of perception, specifically the theory called Gestalt. As the material contained in the tangible components, and sentient, such a relationship is required for duality of materialization, which is achieved by the use of their material expression of immateriality. This expression gives the truth of immateriality (natural materials, tactile value (structure and texture and the 'movement' of the material (the ability to transform. Author's access to the material as an instrument of expression immaterial, provided the concept of minimalist architecture at a higher artistic level (Peter Cumtor and causing severe emotional reaction when meeting also created architectural works (Tadao Ando. Transformations of materials are achieved through the exploration of new treatments and techniques (Kengo Kuma, and the development of technology to unimaginable limits changes the way of understanding reality (Herzog & de Meron. Researching of materials, in the way of its application, can be achieved understanding of minimalism in the architecture as an idea.

    2015-01-01

    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’.

  6. Color as a language in architecture

    Science.gov (United States)

    Smedal, Grete

    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.

  7. Architectural Renovations of Body-As-Temple.

    Science.gov (United States)

    Carroll, Timothy

    2016-07-01

    This paper addresses the Christian religious tradition of understanding the human body as the 'temple of the Holy Spirit' within the context of body modification in Eastern Orthodox Christianity. Drawing on ethnographic research in Jerusalem and Kansas City, interviews with artists and Orthodox Christians, and theological discourses on the body and art, this paper seeks to understand how the body is treated by Orthodox Christians and evaluates the ethical commitments and contestations around the human body and religious practice. The paper focuses specifically on tattooing practices, which, though typically prohibited in conservative forms of Christianity, are nonetheless practiced as a means of devotion in specific Eastern Orthodox Christian settings. These modifications to the body are taken in dialogue with ritual and practical concerns exhibited in Eastern Orthodox burial practice. The paper argues that while there are commonalities across Eastern Orthodox practice, the ethical implications of specific actions are highly contextualized and must be interpreted within local regimes of aesthetic behaviour.

    Leszek Siwik

    2013-01-01

    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

    2015-01-01

    Full Text Available Hirsutism is one of the most prevalent health problems in women. The aim of the study was to compare the effect of 755 nm alexandrite hair removal laser with that of alexandrite laser plus topical licorice on the improvement of idiopathic hirsutism. A double-blind, randomized placebo-controlled study was performed on 90 female subjects. The patients were divided into two groups: alexandrite laser plus 15% licorice gel (group A and placebo (group B. Each subject received one of both products over one side of the face, twice daily for 24 weeks on the hirsute locations. Each group underwent five sessions of alexandrite laser at 6-week intervals. To minimize the effects of confounding variables, the test was performed on two separate zones of patients’ skin. The mean ± SD numbers of terminal hairs in group A were 7.05 ± 4.55 for zone 1 and 6.06 ± 3.70 for zone 2. In group B, they were 3.18 ± 1.75 for zone 1 and 2.49 ± 1.63 for zone 2. The difference in the mean number of terminal hairs was statistically significant between the two groups (p<0.001, and there were no serious adverse reactions. The treatment of idiopathic hirsutism with 755 nm alexandrite laser plus topical licorice is more effective than alexandrite laser only.

    Pagán Carrasco, S; Arranz Maestro, D

    2017-09-01

    Conjunctival intraepithelial neoplasia is a pre-malignant lesion of the ocular surface. It can be treated with topical interferon alpha-2b (INF α-2b) as first choice. A 71-year-old man referred for corneal-conjunctival, gelatinous lesion in the left eye (LE) with an area of almost 270°. The clinical diagnosis was compatible with a corneal-conjunctival intraepithelial neoplasia. Topical treatment was started with INF α-2b at a dose of one million international units (IU)/ml, 4 times/day for 4 months, with remission being achieved. The isolated use of topical INF α-2b is an effective treatment as a first option in the case of corneal-conjunctival intraepithelial neoplasia, positioning itself as a form of effective and safe treatment compared to other therapeutic options. Surgical excision and use of other chemotherapy agents could lead to severe limbic deficits and other side effects. Copyright © 2017 Sociedad Española de Oftalmología.

  14. Expressionism as the radical creative tendency in architecture

    Directory of Open Access Journals (Sweden)

    Alfirević Đorđe

    2012-01-01

    Full Text Available The concepts of expression, expressiveness and expressionism present the key terms on which contemporary architectural and artistic works are based. Although these are essential esthetic categories, the explanations of these concepts are not clearly defined in scientific and theoretical texts. When the term expressionism is mentioned, it often implies the stylistic direction in architecture and the arts, which was created and lasted until the beginning of the XX century in northern Europe (especially in Germany and the Netherlands, and in which the artists have twisted the reality with exaggerated and energetic strokes to express their inner visions, ideas or emotions. However, contemporary theoretical discussions in the arts and architecture point to the manifestation of expressionism in other periods and contexts as well. The basic aim of the text is a critical discourse of interrelations among esthetic categories of expression, expressiveness and expressionism; reexamination of their positions and roles in the system of visual expression, as well as the examination of the starting hypothesis in research, according to which expressionism in architecture is a radical creative tendency with distinctive choleric-sanguine characteristics.

  15. Random curds as mathematical models of fractal rhythm in architecture

    Directory of Open Access Journals (Sweden)

    Ćirović Ivana

    2014-01-01

    Full Text Available The author Carl Bovill has suggested and described a method for generating rhythm in architecture with the help of random curds, as they are the mathematical models of unpredictable and uneven groupings which he recognizes in natural shapes and in natural processes. He specified the rhythm generated in this way as the fractal rhythm. Random curds can be generated by a simple process of curdling, as suggested by B. Mandelbrot. This paper examines the way in which the choice of probability for every stage or level of the curdling process, and the number of stages in the procedure of curdling, affect the characteristics of the obtained fractal object as a potential mathematical model of rhythm in the design process. At the same time, this paper examines the characteristics of rhythm in architecture which determine whether the obtained fractal object will be accepted as an appropriate mathematical model of the observed rhythm.

    Full Text Available The present paper deals with a problem of conservation and adaptive reuse of industrial heritage architecture. The relevance and topicality of the problem of adaptive reuse of industrial heritage architecture for new social and municipal functions as the conservation concept are defined. 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.

    Directory of Open Access Journals (Sweden)

    Yulia eSandamirskaya

    2014-01-01

    Full Text Available Dynamic Field Theory (DFT is an established framework for modelling 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 analogue 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.

  4. Topics in effective field theory as applied to lattice QCD

    Science.gov (United States)

    Smigielski, Brian

    This thesis focuses on understanding aspects of hadronic physics using numerical and analytic computations which comprise the research fields of Lattice QCD and Effective Field Theories. Lattice QCD is a numerical approximation to QCD that is computed within a finite spacetime volume, a finite lattice spacing, and unphysically large values of the quark mass used to limit computational run time. Because Lattice QCD calculations are implemented with these constraints, it becomes necessary to understand how these constraints influence the physics if we are to extract physical observables. This requires the use and matching of an effective field theory for mesons and baryons which are the fundamental degrees of freedom of the effective field theory Lagrangian. We consider pion and nucleon interactions in Chapter 3 when computational demands force the use of small, spacetime lattices, and extract the axial charge of the nucleon. In Chapters 4 and 5 we examine systems of up to twelve particles of single species, pions or kaons, and mixed species systems of pions and kaons. From these systems we learn about the scattering lengths and three-body forces of these particles. These multi-particle systems also allow one to understand the behavior of finite density systems on the lattice. Lastly in Chapter 6, we examine parton distributions of the pion for a nonzero change in the pion's momentum. These are known as generalized parton distributions and reveal information regarding the valence quarks within a particular hadron. Before the advent of QCD, however, these particles were also known as partons.

  5. Solid effervescent formulations as new approach for topical minoxidil delivery.

    Currently marketed minoxidil formulations present inconveniences that range from a grease hard aspect they leave on the hair to more serious adverse reactions as scalp dryness and irritation. In this paper we propose a novel approach for minoxidil sulphate (MXS) delivery based on a solid effervescent formulation. The aim was to investigate whether the particle mechanical movement triggered by effervescence would lead to higher follicle accumulation. Preformulation studies using thermal, spectroscopic and morphological analysis demonstrated the compatibility between effervescent salts and the drug. The effervescent formulation demonstrated a 2.7-fold increase on MXS accumulation into hair follicles casts compared to the MXS solution (22.0±9.7μg/cm(2) versus 8.3±4.0μg/cm(2)) and a significant drug increase (around 4-fold) in remaining skin (97.1±29.2μg/cm(2)) compared to the drug solution (23.5±6.1μg/cm(2)). The effervescent formulations demonstrated a prominent increase of drug permeation highly dependent on the effervescent mixture concentration in the formulation, confirming the hypothesis of effervescent reaction favoring drug penetration. Clinically, therapy effectiveness could be improved, increasing the administration interval, hence, patient compliance. More studies to investigate the follicular targeting potential and safety of new formulations are needed.

    Recent achievements of computer science provide unrivaled power for the advancement of ecology. This power is not merely computational: parallel computers, having hierarchical organization as their architectural principle, also provide metaphors for understanding complex systems. In this sense they might play for a science of ecological complexity a role like equilibrium-based metaphors had in the development of dynamic systems ecology. Parallel computers provide this opportunity through an informational view of ecological reality and multilevel modelling paradigms. Spatial and individual-oriented models allow application and full understanding of the new metaphors in the ecological context.

    Alterations made in the architectural design can be considered as a continuous process, from its conception to the moment a built environment is already in use. This article focuses on the "moving phase", which is the initial moment of the environment occupation and the start-up of services. It aims to show that the continuity of ergonomics interventions during the "moving phase" or start up may reveal the built environment inadequacies; clearly showing needs not met by the design and allowing making instant decisions to solve non-foreseen problems. The results have revealed some lessons experienced by users during a critical stage not usually included in the design process.

    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.

    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.

  19. Hierarchical Surface Architecture of Plants as an Inspiration for Biomimetic Fog Collectors.

    Science.gov (United States)

    Azad, M A K; Barthlott, W; Koch, K

    2015-12-01

    Fog collectors can enable us to alleviate the water crisis in certain arid regions of the world. A continuous fog-collection cycle consisting of a persistent capture of fog droplets and their fast transport to the target is a prerequisite for developing an efficient fog collector. In regard to this topic, a biological superior design has been found in the hierarchical surface architecture of barley (Hordeum vulgare) awns. We demonstrate here the highly wettable (advancing contact angle 16° ± 2.7 and receding contact angle 9° ± 2.6) barbed (barb = conical structure) awn as a model to develop optimized fog collectors with a high fog-capturing capability, an effective water transport, and above all an efficient fog collection. We compare the fog-collection efficiency of the model sample with other plant samples naturally grown in foggy habitats that are supposed to be very efficient fog collectors. The model sample, consisting of dry hydrophilized awns (DH awns), is found to be about twice as efficient (fog-collection rate 563.7 ± 23.2 μg/cm(2) over 10 min) as any other samples investigated under controlled experimental conditions. Finally, a design based on the hierarchical surface architecture of the model sample is proposed for the development of optimized biomimetic fog collectors.

    The fundamental mechanism of photodynamic therapy (PDT)-induced cell death has been characterized, but early critical PDT events in vivo remain incompletely defined. With the recent development in advanced fluorescence imaging modalities, such as intravital 2-photon laser scanning microscopy (2P-LSM), researchers are now able to investigate and visualize biological processes with high resolution in real time. This powerful imaging technology allows deep tissue visualization with single-cell resolution, thus providing dynamic information on the 3-dimensional architectural makeup of the tissue. The main goal of this study was to determine the cutaneous penetration of a topically applied photosensitizer, the silicon phthalocyanine Pc 4, into the skin of live animals and to assess the effective absorption of Pc 4 through the skin barrier. Our 2P-LSM images indicate that Pc 4 penetrates to the epidermal/dermal junction of mouse skin. The data also indicate that the degree of Pc 4 absorption is dose dependent. These findings represent initial steps that may help in improving the clinical utilization of topical Pc 4-PDT.

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 through reducing the total pairwise edge resistance in the grid, which increases the robustness of power transmission between generators and loads against random line failures. We then embed our models in spatial areas of different aspect ratios and study how this geometric factor affects the network structure, as well as the box-counting fractal dimension of the grids generated by our models.

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

    Fang, Jia-You; Leu, Yann-Lii; Chang, Chia-Chun; Lin, Chia-Hsuan; Tsai, Yi-Hung

    2004-01-01

    The application of lipid nano/submicron emulsions as topical drug carrier systems for the percutaneous absorption of flurbiprofen was investigated. The lipid emulsions were made up of isopropyl myristate (IPM), soybean oil, or coconut oil as the oil phase, egg lecithin as the predominant emulsifier, and double-distilled water as the external phase. Stearylamine (SA) and deoxycholic acid (DA) also were used to produce positively and negatively charged emulsions. To evaluate the physicochemical properties of the lipid emulsions, particle size by laser light scattering, the image of atomic force microscopy, and relaxation time values by Nuclear Magnetic Resonance (NMR) were determined. The in vitro permeation data showed that incorporation of SA significantly reduced the topical delivery of flurbiprofen. On the other hand, incorporation of DA exhibited no or a negligible effect on drug permeation. Enhancement of drug absorption was observed when adding oleic acid as part of the oil phase. The in vivo topical application of flurbiprofen from selected lipid emulsions showed a similar trend to the in vitro status. Furthermore, the intersubject variability was considerably reduced by lipid emulsions than by aqueous suspensions in both the in vitro and in vivo experiments. The irritant profiles of lipid emulsions showed that IPM elicited higher irritation than soybean oil. The incorporation of oleic acid also produced skin disruption. The results in the present study suggest the feasibility of lipid emulsions for the topical delivery of flurbiprofen.

    Mcmillan, Gary B.

    1988-01-01

    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.

  1. Treatment of corneal squamous cell carcinoma using topical 1% 5-fluorouracil as monotherapy.

    Science.gov (United States)

    Dorbandt, Daniel M; Driskell, Elizabeth A; Hamor, Ralph E

    2016-05-01

    The purpose of this report is to discuss the use of topical 1% 5-fluorouracil as a sole therapy for canine corneal squamous cell carcinoma (SCC). A 12-year-old castrated male pug was evaluated for a well-demarcated, central, 3 mm in diameter, pale pink, raised, right corneal mass. An incisional biopsy was obtained using a #64 beaver blade after topical anesthesia and without sedation. A definitive diagnosis of corneal SCC was obtained after histopathologic evaluation of the biopsy. Topical 1% 5-fluorouracil ointment was applied to the right eye four times daily for 2 weeks followed by no treatment for 2 weeks, then treatment again twice daily for 2 weeks. The cornea remained free of recurrence 10 months after cessation of treatment. In dogs affected with corneal SCC, topical 1% 5-fluorouracil monotherapy may be a viable and cost-effective treatment option with minimal side effects. This chemotherapy agent may also have an effect on corneal pigmentation. Chronic cyclosporine therapy did not contribute to the pathogenesis of corneal SCC in the case described.

    To determine whether recent use of topical fluoroquinolones is a risk factor for in vitro fluoroquinolone resistance in Staphylococcus aureus ocular isolates. Disk diffusion susceptibility testing for ciprofloxacin, moxifloxacin, and gatifloxacin was performed for all ocular isolates of S aureus at the Francis I. Proctor Foundation microbiology laboratory from January 1, 2005, to December 31, 2008. The medical records of patients with positive S aureus cultures were reviewed to determine topical or systemic fluoroquinolone use within the 3 months prior to culture. The Fisher exact test was used to compare the proportion of patients who used topical fluoroquinolones in the past 3 months among fluoroquinolone-sensitive and -resistant cases. Logistic regression was used to determine risk factors for fluoroquinolone resistance. Of 200 S aureus cultures, 41 were resistant to ciprofloxacin, moxifloxacin, and gatifloxacin (20.5%). Fluoroquinolone-resistant S aureus isolates were from older patients (mean [SD] age, 65.5 [25.0] years) compared with fluoroquinolone-susceptible isolates (mean [SD] patient age, 52.1 [22.1] years) (P = .003). Use of fluoroquinolones within the 3 months before testing was more frequent in resistant isolates (29%) than in susceptible isolates (11%) (P = .005), as was recent hospitalization (22% of resistant isolates, 0% of susceptible isolates) (P fluoroquinolone use within 3 months was a significant predictor of fluoroquinolone resistance (P = .046), along with age, systemic immunosuppression, and topical fluoroquinolone use between 3 and 6 months before testing. Recent topical fluoroquinolone use is significantly associated with fluoroquinolone resistance in S aureus isolates from ocular cultures.

    The university of XYZ is located in Bandung, West Java. It has an infrastructure of technology information (IT) which is managed independently. Currently, the IT at the University of XYZ employs a complex conventional management pattern that does not result in a fully integrated IT infrastructure. This is not adaptive in addressing solutions to changing business needs and applications. In addition, it impedes the innovative development of sustainable IT services and also contributes to an unnecessary high workload for managers. This research aims to establish the concept of IS/IT strategic planning. This is used in the development of the IS/IT and in designing the information technology infrastructure based on the framework of The Open Group Architecture Framework (TOGAF) and Architecture Development Method (ADM). A case study will be done at the University of XYZ using the concept of qualitative research through review of literatures and interviews. This study generates the following stages:(1) forming a design using TOGAF and the ADM around nine functional areas of business and propose 12 application candidates to be developed at XYZ University; (2) generating 11 principles of the development of information technology architecture; (3) creating a portfolio for future applications (McFarlan Grid), generating 6 applications in the strategic quadrant (SIAKAD-T, E-LIBRARY, SIPADU-T, DSS, SIPPM-T, KMS), 2 quadrant application operations (PMS-T, CRM), 4 quadrant application supports (MNC-T, NOPEC-T, EMAIL-SYSTEM, SSO); and (4) modelling the enterprise architecture of this study which could be a reference in making a blueprint for the development of information systems and information technology at the University of XYZ.

    Topical hemostatic agents can be used to treat problematic bleedings in patients who undergo surgery. Widely used are the collagen- and gelatin-based hemostats. This study aimed to develop a fully synthetic, biodegradable hemostatic agent to avoid exposure to animal antigens. In this in vitro study the suitability of different newly developed polyurethane-based foams as a hemostatic agent has been evaluated and compared to commonly used agents. An experimental in vitro test model was used in which human blood flowed through the test material. Different modified polyurethane foams were compared to collagen and gelatin. The best coagulation was achieved with collagen. The results of the polyurethane foam improved significantly by increasing the amount of polyethylene glycol. Therefore, the increase of the PEG concentration seems a promising approach. Additional in vivo studies will have to be implemented to assess the application of polyurethane foam as a topical hemostatic agent.

    This paper will discuss the challenges faced by architectural education today. It takes as its starting point the double commitment of any school of architecture: on the one hand the task of preserving the particular knowledge that belongs to the discipline of architecture, and on the other hand...... the obligation to prepare students to perform in a profession that is largely defined by forces outside that discipline. It will be proposed that the autonomy of architecture can be understood as a unique kind of information: as architecture’s self-reliance or knowledge-about itself. A knowledge...... that is not scientific or academic but is more like a latent body of data that we find embedded in existing works of architecture. This information, it is argued, is not limited by the historical context of the work. It can be thought of as a virtual capacity – a reservoir of spatial configurations that can...

    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.

    2012-01-01

    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.

    2013-02-01

    Full Text Available The aim of the paper is to determine the scope and content of Croatian research output in the field of book history, determine which Croatian journals publish papers on book history, the topics covered and the number of scholars who do research in this field. The research was conducted on the corpus of 177 papers published in 17 Croatian journals from 2001 to 2010. The data collected indicates that few journals regularly publish papers on book history, and only one journal explicitly states book history as its major area of interest. Furthermore, it is evident that very few scholars regularly or occasionally do research on book history. The topics covered in selected papers bear witness to a wide range of interests, but only few papers follow recent trends in world book history research. This paper, however, does not cover scholarly or trade monographs and conference proceedings published during the time under investigation, which is one of the limitations of the current research. Still, the output in scholarly and trade journals, which are the main channels of scholarly communication, provides a relevant sample for determining the incidence of book history as a research topic in Croatian science. These findings are the main research contribution of this paper.

    In recent years, a number of studies have reported on Resina Draconis (RD) as a topical treatment for pressure ulcers. To evaluate these studies, we performed a systematic review and meta-analysis aimed to examine the efficacy of RD for pressure ulcers. We searched eight electronic databases to identify randomized controlled trials in which RD treatment was compared with other topical treatment of pressure ulcers from 1980 to 2014. Selection of studies, study appraisal, data extraction and analysis were undertaken using standard methods. Fourteen randomized controlled trials were included involving 618 patients. The results of the meta-analysis showed that, RD treatment was significantly associated with a higher healing rate for pressure ulcers (risk ratio 2.07, 95% confidence intervals 1.73-2.48, p < 0.001). The results of descriptive analysis showed that, compared with the control group, RD treatment shortened healing time. As for safety, adverse reactions had not been reported. These results suggest that RD can improve the healing rate for pressure ulcers and shorten the healing time, compared with other topical treatments. However, due to limited quality and quantity of the included studies, this conclusion needs to be proved by more high quality studies.

    Purpose of this study was to establish a lecithin nanoemulsion (LNE) without any synthetic surfactant as a topical delivery vehicle and to evaluate its topical delivery potential by the following factors: particle size, morphology, viscosity, stability, skin hydration and skin penetration. Experimental results demonstrated that an increasing concentration of soybean lecithin and glycerol resulted in a smaller size LNE droplet and increasing viscosity, respectively. The droplet size of optimized LNE, with the glycerol concentration above 75% (w/w), changed from 92 (F10) to 58 nm (F14). Additionally, LNE, incorporated into o/w cream, improved the skin hydration capacity of the cream significantly with about 2.5-fold increase when the concentration of LNE reached 10%. LNE was also demonstrated to improve the penetrability of Nile red (NR) dye into the dermis layer, when an o/w cream, incorporated with NR-loaded LNE, applied on the abdominal skin of rat in vivo. Specifically, the arbitrary unit (ABU) of fluorescence in the dermis layer that had received the cream with a NR-loaded LNE was about 9.9-fold higher than the cream with a NR-loaded general emulsion (GE). These observations suggest that LNE could be used as a promising topical delivery vehicle for lipophilic compounds.

    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.

  2. Some Aspects of Recognizing Lithuanian Modern Architecture as Protected Heritage. Case of Postmodernism

    Directory of Open Access Journals (Sweden)

    Martynas Mankus

    2017-05-01

    Full Text Available Recently, objects of the so-called “modern heritage” have been gaining more and more attention from heritage protection institutions. The majority of buildings of the period does not comply with the formal 50-year age requirement applicable to protected objects. Respectively, it is more complicated to establish their valuable qualities, and this often provokes all kinds of conflicts. Samples of such architecture decline, or the issue of their value is resolved in the presence of actual threat to their physical condition. By taking into consideration one of the “youngest” periods – the architecture of postmodernism, the article aims at reviewing the context of fixing the criteria for recognizing modern architecture as protected heritage. With a hypothesis being raised that compliance with a certain historical and stylistic trend should be considered a sign of valuable architecture, the chronological and aesthetic evaluation perspectives of postmodern architecture and features of its expression are discussed in the article.

    Full Text Available Minimalism is now accepted as the definition of culture by way of reasoning, that is, as an aesthetic approach to navigating through the different fields, such as art, architecture, music, fashion design and critical discussions. It is a contemporary need for simplicity, order and purity of the individual come from history, examples of which is essential for the growing emergency needs, and which may be a way to throw a new light. In Japanese culture, architecture has the longest history. The ideal of simplicity in the Japanese architectural tradition is specific - from the Ise shrine or the heroic simplicity of architecture and rituals, as well as aesthetic ideals through the ceremony of tea and Katsura Palace Rikju to this great names on the international architectural scene: Tadao Ando, or SANAA. Japanese concept of a zen, who was in the minimum way of life always offered a sense of liberation, a chance to be in touch with the essence of being, influenced by traditional Japanese architecture in a way that not only left an indelible mark in the past, but present a new way today, not only in Japan but also abroad. Minimalism in architecture is a contemporary sensitivity that living beyond all religions, rejects superior materialism and takes the search for spirituality as a new principle of progress.

    The design and development of the modern hospital in Australia had a profound impact on medical practice and research at a variety of levels. Between the late 1920s and the 1950s hospital architects, administrators, and politicians travelled widely in order to review the latest international developments in the hospital field They were motivated by Australia's geographic isolation and a growing concern with how to govern the population at the level of physical health. While not 'medical research' in the conventional sense of the term, this travel was a powerful generator of medical thinking in Australia and has left a rich archival legacy. This paper draws on that archive to demonstrate the ways in which architectural research and international networks of hospital specialists profoundly shaped the provision of medical infrastructure in Australia.

    Eugenol is the main constituent of clove oil with anti-inflammatory properties. In this work, for the first time, O/W nanoemulsion of eugenol was designed for the evaluation of anti-inflammatory effects as a topical delivery system. Topical formulations containing 1%, 2% and 4% of eugenol as well as a nanoemulsion system containing 4% eugenol and 0.5% piroxicam were prepared. Further to physicochemical examinations, such as determination of particle size, polydispersity index, zeta potential and physical stability, anti-inflammatory activity was examined in carrageenan-induced paw edema in rats. The optimum formulation was found to contain 2% eugenol (oil phase), 14% Tween 20 (surfactant) and 14% isopropyl alcohol (co-surfactant) in water. Nanoemulsion with polydispersity index of 0.3 and median droplet diameter of 24.4 nm (d50) was obtained. Animal studies revealed that the nanoemulsions exhibited significantly improved anti-inflammatory activity after 1.5 h, compared with marketed piroxicam gel. Additionally, it was shown that increasing the concentration of eugenol did not show higher inhibition of inflammation. Also, the nanoemulsion having piroxicam showed less anti-inflammatory properties compared with the nanoemulsion without piroxicam.

    2016-01-01

    We recently demonstrated that statins mediate protection against intracellular pathogens, Mycobacterium tuberculosis and Listeria monocytogenes in mice. Here, we investigated the immunomodulatory potential of simvastatin as a topical or systemic host-directed drug therapy in controlling inflammatory responses in an experimental mouse model of cutaneous leishmaniasis caused by Leishmania major (LV39). In an ear infection model, topical application of simvastatin directly on established lesions significantly reduced severity of the disease reflected by ear lesion size and ulceration. The host protective effect was further accompanied by decreased parasite burden in the ear and draining lymph nodes in both BALB/c and C57BL/6 mice. Pre-treatment of these mice on a low-fat cholesterol diet and systemic simvastatin also reduced footpad swelling, as well as parasite burdens and ulceration/necrosis in the more robust footpad infection model, demonstrating the prophylactic potential of simvastatin for cutaneous leishmaniasis. Mechanistically, following L. major infection, simvastatin-treated primary macrophages responded with significantly reduced cholesterol levels and increased production of hydrogen peroxide. Furthermore, simvastatin-treated macrophages displayed enhanced phagosome maturation, as revealed by increased LAMP-3 expression in fluorescent microscopy and Western blot analysis. These findings demonstrate that simvastatin treatment enhances host protection against L. major by increasing macrophage phagosome maturation and killing effector functions. PMID:27632901

    Full Text Available The architecture of villas stands out as one of the recognizable characteristics of Vrnjačka Banja's physical structure and as a distinctive type of objects forming the tourist offer. Analyses of position, function and importance of villa architecture in shaping the identity of Vrnjačka Banja are based on the conviction that organized space and built environment, as a result of design and planning processes, have decisive role in forming the identity of places and making them recognizable. In this paper, architectural elements that characterize this type of objects are being analyzed. Also, the role that singled out elements have at higher urban levels, firstly in creating characteristic, recognizable architectural and urban ensembles, and consequently in identity forming, is pointed out. These issues are considered in terms of tourism development, as a precondition for making recognizable city with possibilities for branding, that consequently improve the exploiting of the tourist potentials.

This information, it is argued, is not limited by the historical context of the work. It can be thought of as a virtual capacity – a reservoir of spatial configurations that can...... the obligation to prepare students to perform in a profession that is largely defined by forces outside that discipline. It will be proposed that the autonomy of architecture can be understood as a unique kind of information: as architecture’s self-reliance or knowledge-about itself. A knowledge...... be transformed and reapplied endlessly through its confrontation with shifting information from outside the realms of architecture. A selection of architects’ statements on their own work will be used to demonstrate how in quite diverse contemporary practices the re-use of existing architectures is applied...

    Full Text Available Summary: This work was suggested on the basis of presence of curcuminoids in curcuma and the presence of flavonoidal constituent in acacia and lupinus. The aim of this study was to study their possible anti-inflammatory effect by separately formulation of the three extracts in a suitable gel formula for topical administration and comparison of the prepared gels with a standard gel in the market (diclosal Emulgel by using the carrageenan induced paw edema model in albino rats. The extracts were subjected to phytochemical screening tests using reported methods to determine the presence of various phytoconstituents. Gel formulation was prepared containing 8% of each extract separately in gel base, namely sodium carboxy methyl cellulose (NaCMC. The pharmacological screening revealed that percent reduction of edema produced by curcuma extract was 30.0%, by acacia extract was 4%, by ethanol fraction lupinus was 18% and by chloroform fraction lupinus was 11.3%, while diclofenac sodium topical gel produced 48% reduction of edema. Industrial relevance: Medicinal plants provide a host of chemical compounds, which have been optimized on the basis of their biological activities. Chemical compounds present in medicinal plants have shown great promise in the management of various inflammatory disorders and have continued to serve as alternative and complementary therapies. The present study will help the industry to produce herbal drug effective in the treatment of inflammation with less side effect and less costly when compared to the synthetic drugs.

  17. Fractional brownian functions as mathematical models of natural rhythm in architecture.

    Cirovic, Ivana M

    2014-10-01

    Carl Bovill suggested and described a method of generating rhythm in architecture with the help of fractional Brownian functions, as they are mathematical models of natural rhythm. A relationship established in the stated procedure between fractional Brownian functions as models of rhythm, and the observed group of architectural elements, is recognized as an analogical relationship, and the procedure of generating rhythm as a process of analogical transfer from the natural domain to the architectural domain. Since analogical transfer implies relational similarity of two domains, and the establishment of one-to-one correspondence, this paper is trying to determine under which conditions such correspondence could be established. For example, if the values of the observed visual feature of architectural elements are not similar to each other in a way in which they can form a monotonically increasing, or a monotonically decreasing bounded sequence, then the structural alignment and the one-to-one correspondence with a single fractional Brownian function cannot be established, hence, this function is deemed inappropriate as a model for the architectural rhythm. In this case we propose overlapping of two or more functions, so that each of them is an analog for one subset of mutually similar values of the visual feature of architectural elements.

  18. Writing Gardens - Gardening Drawings: Fung, Brunier and Garening as a model of Landscape Architectural Practice

    Directory of Open Access Journals (Sweden)

    Julian Raxworthy

    2004-06-01

    Full Text Available Landscape architecture is different from other design discourses, notably architecture, because of its utilisation of' dynamic' construction media such as plant materials, soils and water, compared with the 'static' materials of architecture, colloquially described as bricks and mortar. This dynamism refers to the fact that landscape materials not only change, but get better over time. While this is a material difference, its implications extend to practice, which has been modelled, from architecture, to favour a static mode of representation: the drawing. While the drawing is important for the propositional nature of landscape architecture, it may be valuable to look at other disciplines, allied to landscape architecture, which might be seen as better able to engage with change. In this essay, the garden provides just such an example. In the writings of Stanislaus Fung on the Chinese garden text the Yuan vi, an argument is made about writing being a fundamental act in the endeavour of gardening that may offer a bridge across the 'ontological disparity' that exists between representation and the subject, the landscape. To speak of writing in this context suggests that writing about gardens is actually a type of gardening in itself. This argument is extended in the current essay quickly to see if it is also appropriate to consider drawings in this way. This essay also attempts to legitimate theoretically the real possibility of modifying landscape architectural practices to engage with change, by suggesting what might be learned from gardening. In further research by this author, this argument will be used as the theoretical basis for critiquing gardens in such a way that lessons learnt from garden designers can be valuably incorporated back into the discourse of landscape architecture.

    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

  1. 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.

    Many medications are available for treatment of pediculosis capitis including ivermectin. Our aim is to compare the efficacy and safety of topical versus oral ivermectin in treatment of pediculosis capitis. Sixty-two patients with proved head lice infestation were included and divided into group I (31 patients; received single topical application of 1% ivermectin) and group II (31 patients; received single dose of oral ivermectin). Treatment was repeated after 1 week for nonresponders. At 1 week after treatment, the eradication rates and improvement of pruritus were significantly higher among patients who received topical than oral ivermectin. When a second treatment, topical or oral, was given to nonresponders, the cure rates of infestation and pruritus was 100% and 97% among patients treated with topical and oral ivermectin, respectively with no significant difference between the two groups. This study suggests that both topical and oral ivermectin demonstrate high efficacy and tolerability in treatment of pediculosis capitis. However, a single treatment with topical ivermectin provides significantly higher cure of infestation and faster relief of pruritus than oral ivermectin. In addition, whether topical or oral ivermectin is used to treat head lice, a second dose is required in some cases to ensure complete eradication. © 2014 Wiley Periodicals, Inc.

  3. Gaining trust as well as respect in communicating to motivated audiences about science topics.

    Expertise is a prerequisite for communicator credibility, entailing the knowledge and ability to be accurate. Trust also is essential to communicator credibility. Audiences view trustworthiness as the motivation to be truthful. Identifying whom to trust follows systematic principles. People decide quickly another's apparent intent: Who is friend or foe, on their side or not, or a cooperator or competitor. Those seemingly on their side are deemed warm (friendly, trustworthy). People then decide whether the other is competent to enact those intents. Perception of scientists, like other social perceptions, involves inferring both their apparent intent (warmth) and capability (competence). To illustrate, we polled adults online about typical American jobs, rated as American society views them, on warmth and competence dimensions, as well as relevant emotions. Ambivalently perceived high-competence but low-warmth, "envied" professions included lawyers, chief executive officers, engineers, accountants, scientists, and researchers. Being seen as competent but cold might not seem problematic until one recalls that communicator credibility requires not just status and expertise but also trustworthiness (warmth). Other research indicates the risk from being enviable. Turning to a case study of scientific communication, another online sample of adults described public attitudes toward climate scientists specifically. Although distrust is low, the apparent motive to gain research money is distrusted. The literature on climate science communicators agrees that the public trusts impartiality, not persuasive agendas. Overall, communicator credibility needs to address both expertise and trustworthiness. Scientists have earned audiences' respect, but not necessarily their trust. Discussing, teaching, and sharing information can earn trust to show scientists' trustworthy intentions.

  5. Modelling of internal architecture of kinesin nanomotor as a machine language.

    Science.gov (United States)

    Khataee, H R; Ibrahim, M Y

    2012-09-01

    Kinesin is a protein-based natural nanomotor that transports molecular cargoes within cells by walking along microtubules. Kinesin nanomotor is considered as a bio-nanoagent which is able to sense the cell through its sensors (i.e. its heads and tail), make the decision internally and perform actions on the cell through its actuator (i.e. its motor domain). The study maps the agent-based architectural model of internal decision-making process of kinesin nanomotor to a machine language using an automata algorithm. The applied automata algorithm receives the internal agent-based architectural model of kinesin nanomotor as a deterministic finite automaton (DFA) model and generates a regular machine language. The generated regular machine language was acceptable by the architectural DFA model of the nanomotor and also in good agreement with its natural behaviour. The internal agent-based architectural model of kinesin nanomotor indicates the degree of autonomy and intelligence of the nanomotor interactions with its cell. Thus, our developed regular machine language can model the degree of autonomy and intelligence of kinesin nanomotor interactions with its cell as a language. Modelling of internal architectures of autonomous and intelligent bio-nanosystems as machine languages can lay the foundation towards the concept of bio-nanoswarms and next phases of the bio-nanorobotic systems development.

  6. Physical Carboxymethylscleroglucan/Calcium Ion Hydrogels as Modified Drug Delivery Systems in Topical Formulations

    Maria Antonietta Casadei

    2009-07-01

    Full Text Available A carboxymethyl derivative of scleroglucan (Scl-CM with a 65±5% carboxylic group degree of derivatization (DD was recently synthesized and characterized. Aqueous solutions of the polymer underwent to a sharp transition toward a gel like behaviour in the presence of divalent ions such as Ca+2. Physical hydrogels with different Scl-CM/Ca+2 ratios were prepared and characterized for their rheological behaviour. Their potential as drug delivery systems was also evaluated. To this end three non steroidal anti-inflammatory drugs (NSAIDs were loaded into the hydrogels obtained with 2% w/v solution of Scl-CM and 0.05 and 0.1 M CaCl2. The release rate of the drugs was critically related to the salt concentration. By an appropriate combination of the hydrogels prepared using different amounts of salt, it was possible to obtain a system able to release diclofenac with zero-order kinetics. Primary skin irritation tests showed a good biocompatibility of the new polymer, as well as of its hydrogels. These results suggest a potential of the new hydrogels for the development of modified delivery systems in topical formulations.

    Propolis shows therapeutic properties ascribed to the presence of some flavonoids, phenolic acids, and their esters; it is a natural multifunctional material, solid at room temperature, and composed mainly of resin and waxes. We therefore used propolis as a lipid material to prepare solid lipid nanoparticles (SLNs); SLNs are proposed bioactive medications for topical intranasal therapy. Suitable formulation parameters were studied and the SLNs obtained by the high shear homogenization method were characterized; a selected formulation was viscosized to increase the residence time. Dimensional, morphological, and solid-state characterizations of the formulated SLNs were performed. In vitro and ex vivo permeation tests of diclofenac sodium, the model drug, and polyphenols were carried out. The propolis amount and surfactant concentration represent the key parameters that affect nanoparticle properties in terms of size, drug and polyphenol content, and physical stability. Size dispersions of about 600 nm and 0.4 PI were obtained, which do not change by increasing the viscosity. Drug is encapsulated in SLNs, as demonstrated by FTIR and DSC analyses. In vitro and ex vivo studies prove that drug and polyphenols do not cross the membranes; therefore, propolis-based SLNs could be used as delivery systems of diclofenac and flavonoids for the local treatment of nasal cavity diseases. Due to propolis composition, the proposed formulation could be used as a bioactive medication in which the carrier can exert a complementary effect with the loaded drug.

    As part of a recent research effort aimed at employing mesoporous materials for controlled drug delivery, this paper presents MCM-41 as a carrier for topical application, using Trolox as a model unstable guest molecule. The complexes between Trolox and MCM-41 were prepared by employing different inclusion procedures, varying solvent, method and pretreatment of the silica matrix. The objectives of this study were to determine Trolox loading, analyze its integrity and availability after immobilization on mesoporous silica, evaluate MCM-41 influence on Trolox photodegradation and establish whether the preparation method significantly influences complex properties. The characterization analyses (XRD, TGA, DSC and FTIR) confirmed the hydrogen-bonding interaction and Trolox structure preservation. Gas-volumetric analysis showed a consistent decrease in surface area and in pore volume and diameter with respect to bare MCM-41 indicating that Trolox was mainly located within mesopores. In vitro diffusion tests showed a slower release of Trolox after inclusion in the MCM-41 matrix; at the same time UV irradiation studies highlighted an increased photostability for the complex particularly in O/W emulsion. Moreover the radical scavenging activity of Trolox was maintained after immobilization. In all cases, differences were observed in all tested samples, suggesting that results could be optimized by modifying the inclusion procedure and by improving the guest loading.

    Full Text Available Topical anesthetics are being widely used in numerous medical and surgical sub-specialties such as anesthesia, ophthalmology, otorhinolaryngology, dentistry, urology, and aesthetic surgery. They cause superficial loss of pain sensation after direct application. Their delivery and effectiveness can be enhanced by using free bases; by increasing the drug concentration, lowering the melting point; by using physical and chemical permeation enhancers and lipid delivery vesicles. Various topical anesthetic agents available for use are eutectic mixture of local anesthetics, ELA-max, lidocaine, epinephrine, tetracaine, bupivanor, 4% tetracaine, benzocaine, proparacaine, Betacaine-LA, topicaine, lidoderm, S-caine patch™ and local anesthetic peel. While using them, careful attention must be paid to their pharmacology, area and duration of application, age and weight of the patients and possible side-effects.

    2016-05-17

    Telemedicine has been promoted by healthcare professionals as an efficient way to obtain remote assistance from specialised centres, to get a second opinion about complex diagnosis or even to share knowledge among practitioners. The current economic restrictions in many countries are increasing the demand for these solutions even more, in order to optimize processes and reduce costs. However, despite some technological solutions already in place, their adoption has been hindered by the lack of usability, especially in the set-up process. In this article we propose a telemedicine platform that relies on a cloud computing infrastructure and social media principles to simplify the creation of dynamic user-based groups, opening up opportunities for the establishment of teleradiology trust domains. The collaborative platform is provided as a Software-as-a-Service solution, supporting real time and asynchronous collaboration between users. To evaluate the solution, we have deployed the platform in a private cloud infrastructure. The system is made up of three main components - the collaborative framework, the Medical Management Information System (MMIS) and the HTML5 (Hyper Text Markup Language) Web client application - connected by a message-oriented middleware. The solution allows physicians to create easily dynamic network groups for synchronous or asynchronous cooperation. The network created improves dataflow between colleagues and also knowledge sharing and cooperation through social media tools. The platform was implemented and it has already been used in two distinct scenarios: teaching of radiology and tele-reporting. Collaborative systems can simplify the establishment of telemedicine expert groups with tools that enable physicians to improve their clinical practice. Streamlining the usage of this kind of systems through the adoption of Web technologies that are common in social media will increase the quality of current solutions, facilitating the sharing of

  19. Assessment of "corticophobia" as an indicator of non-adherence to topical corticosteroids: A pilot study.

    2017-03-01

    Concerns regarding topical corticosteroid (TCS) use, broadly known as "corticophobia", are highly prevalent among dermatology patients and often result in non-adherence to TCS. This non-adherence contributes to poor disease control and increased health care costs. However, it is unknown if assessment of these concerns might help to identify patients at risk of TCS-non-adherence. Clinical tools indicating non-adherence could be helpful to improve management of this patient group. To assess whether the available tools for measuring concerns regarding corticosteroids, the TOPICOP scale and the 0-10 Visual Analogue Scale (VAS), could help to detect non-adherence to TCS. In 75 patients with concerns regarding TCS use both the TOPICOP scale and VAS were anonymously assessed. A comparison was made between TCS-adherent and non-adherent patients regarding the intensity and characteristics of their concerns. The intensity and quality of the concerns varied broadly among the patients. When using the VAS, a score of ≥5 detected 87% of non-adherent patients. The answers to the TOPICOP scale did not discriminate non-adherent from adherent patients. Using the VAS to assess concerns to use TCS could help identify patients at risk of TCS-non-adherence and facilitate discussion with the patient about potential non-adherence in a more substantiated, non-judgemental way.

  20. Working Capital Management as a routine: An action based access to the topic

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available In times of unstable capital markets on the one side and historically low interests on the other, working capital management must be discussed from different perspectives. Limited sources of liquidity, and the high refinancing risk of lending companies, make the reduction of current assets and liabilities an even more important management task than before. On the other hand, low interest rates raise the need for defining the optimum level for working capital. Little research and empirical evidence exists when it comes to lifting working capital targets to create value. The objective of the present paper is to give evidence on whether German companies adapt their behavior in terms of handling working capital in the actual economic environment and to describe which practices have been established to perform this adaptation. The given analysis is based on a qualitative study. The data used have been gathered in 2014 and 2015 during semi structured interviews with CFOs or financial executives of 15 German and Austrian industrial firms. Our study suggests that adaptation is realized rather by moderating management attention and focus to the topic of capital cost but not by adjusting the financial targets themselves. This is because working capital reduction as become a management routine.

  4. Physics of climate change, taught as a topics a course for undergraduate physics majors

    Sadler, Michael

    2012-10-01

    While anthropogenic (human-caused) climate change is generally accepted in the scientific community, there is considerable skepticism among the general population. Science students are often asked by their peers, family members, and others, whether they ``believe'' climate change is occurring and what should be done about it (if anything). While the pertinent material is covered in undergraduate physics courses, it helps to review the basics in order to develop an educated perspective on this topic that is very volatile (socially and politically). The basic topics are introductory quantum mechanics (discrete energy levels of atomic systems), molecular spectroscopy, blackbody radiation, and appreciation for the scientific method (particularly peer-reviewed research). These topics are usually covered in undergraduate modern physics and thermodynamics courses, but a separate course on climate change (taught in Spring 2012) helped ``put things together'' for both the students and their professor.

    2003-01-01

    Purpose: To determine whether 2% Lidocaine injection is an effective topical anesthetic agent for non-phaco small incision cataract surgery.Setting: Charity eye clinic supported by Hellen Keller International.Methods:One hundred and twenty-five consecutive cataract surgery patients received topical anesthesia with 2% Lidocaine injection solution just 1 and 0.5 minutes prior to non-phaco small incision cataract extraction and intraocular lens implantation. Each patient was asked about pain or piessure sensation during the operation.Results: The surgeon felt ease in the operations. Many patients (93/125) were comfort during the whole surgery. Only 9 patients′ score was above level 3,mostly complained during the nucleus extraction; Among those whose score was level 1~2, 82.6%(19/23)claimed discomfort at middle of the operation (nucleus extraction) or the beginning (creating the conjunctival flap).Conclusion: Lidocaine injection solution(2%) was an effective topical anesthesia agent in cataract surgery.

    2014-01-01

    Background: Systemic treatment with propranolol is proven to be effective for patients with hemangiomas with less side-effect. We used a propranolol gel for topical use on hemangiomas. Methods: In this retrospective study, we analyzed 148 patients who had been treated topically with propranolol gel for 12 weeks. We analyzed the data of patients and clinically gave each hemangioma a "hemangioma score" to determine the treatment success. Results: In 147 of the 148 patients, strong signs of resolution under treatment included lightening, paling, and less vascularization. The hemangioma score showed a signifi cant decrease during the treatment. Relevant serum levels of propranolol were not found. Adverse effects were rare and not related to propranolol. Conclusion: Topical treatment with propranolol gel is suitable for specific hemangiomas in addition to cryotherapy and systemic treatment with propranolol.

    We propose and demonstrate colloidal quantum dot hybridized, radial p-n junction based, nanopillar solar cells with photovoltaic performance enhanced by intimately integrating nanocrystals to serve as light harvesting agents around the light trapping pillars. By furnishing Si based nanopillar photovoltaic diodes with CdSe quantum dots, we experimentally showed up to sixfold enhancement in UV responsivity and ˜13% enhancement in overall solar conversion efficiency. The maximum responsivity enhancement achieved by incorporation of nanocrystals in the nanopillar architecture is found to be spectrally more than four times larger than the responsivity enhancement obtained using planar architecture of the same device.

    In dental practice, local anesthesia causes pain, fear, and stress, and is frequently the reason that patients abandon treatment. Topical anesthetics are applied in order to minimize the discomfort caused by needle insertion and injection, and to reduce the symptoms of superficial trauma at the oral mucosa, but there are still no efficient commercially available formulations. Factorial design is a multivariate data analysis procedure that can be used to optimize the manufacturing processes of lipid nanocarriers, providing valuable information and minimizing development time. This work describes the use of factorial design to optimize a process for the preparation of nanostructured lipid carriers (NLC) based on cetyl palmitate and capric/caprylic triglycerides as structural lipids and Pluronic 68 as the colloidal stabilizer, for delivery of the local anesthetics lidocaine and prilocaine (both at 2.5%). The factors selected were the excipient concentrations, and three different responses were followed: particle size, polydispersity index and zeta potential. The encapsulation efficiency of the most effective formulations (NLC 2, 4, and 6) was evaluated by the ultrafiltration/centrifugation method. The formulations that showed the highest levels of encapsulation were tested using in vitro release kinetics experiments with Franz diffusion cells. The NLC6 formulation exhibited the best sustained release profile, with 59% LDC and 66% PLC released after 20h. This formulation was then characterized using different techniques (IR-ATR, DSC, DRX, TEM, and NTA) to obtain information about its molecular organization and its physicochemical stability, followed during 14months of storage at 25°C. This thorough pre-formulation study represents an important advance towards the development of an efficient pre-anesthetic for use in dentistry.

    Robert R. Hewitt

    2014-02-01

    Full Text Available The literature review examines globalization and landscape architecture as discourse, samples its various meanings, and proposes methods to identify and contextualize its specific literature. Methodologically, the review surveys published articles and books by leading authors and within the WorldCat.org Database associated with landscape architecture and globalization, analyzing survey results for comprehensive conceptual and co-relational frameworks. Three “higher order” dimensions frame the review’s conceptual organization, facilitating the organization of subordinate/subtopical areas of interest useful for comparative analysis. Comparative analysis of the literature suggests an uneven clustering of discipline-related subject matter across the literature’s “higher order” dimensions, with a much smaller body of literature related to landscape architecture confined primarily to topics associated with the dispersion of global phenomena. A subcomponent of this smaller body of literature is associated with other fields of study, but inferentially related to landscape architecture. The review offers separate references and bibliographies for globalization literature in general and globalization and landscape architecture literature, specifically.

    Many topics which are closely related can be found in the national curriculum of the Czech Republic for physics and biology. One of them is the heart and the circulatory system in the human body. This topic was examined cross curriculum, a teaching module was created and the topic was chosen for our research. The task was to determine if the students of bachelor study are aware of connections between physics and biology within this topic and whether we can help them effectively to describe the corresponding physics phenomena in the human body connected, for example, with a heart attack or with the measurement of blood pressure. In this paper, the heart and the circulatory system are presented as suitable topics for an interdisciplinary teaching module which includes both theoretical and experimental parts. The module was evaluated by a group of first-year undergraduate students of physics at the Faculty of Science, Palacký University. The acquired knowledge was compared with another control group through a test. The highest efficiency of the module was evaluated on the basis of questions that covered the calculation problems.

    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.

    2011-07-01

    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. © 2011 The Authors.

    2015-01-01

    Full Text Available The aim of the paper is to draw attention to the view that the two key elements in achieving good quality of architecture infill in immediate, current surroundings, are the selection of optimal creative method of infill architecture and adequate application of 'the bond' as integrative element, The success of achievement and the quality of architectural infill mainly depend on the assessment of various circumstances, but also on the professionalism, creativity, sensibility, and finally innovativeness of the architect, In order for the infill procedure to be carried out adequately, it is necessary to carry out the assessment of quality of the current surroundings that the object will be integrated into, and then to choose the creative approach that will allow the object to establish an optimal dialogue with its surroundings, On a wider scale, both theory and the practice differentiate thee main creative approaches to infill objects: amimetic approach (mimesis, bassociative approach and ccontrasting approach, Which of the stated approaches will be chosen depends primarily on the fact whether the existing physical structure into which the object is being infilled is 'distinct', 'specific' or 'indistinct', but it also depends on the inclination of the designer, 'The bond' is a term which in architecture denotes an element or zone of one object, but in some instances it can refer to the whole object which has been articulated in a specific way, with an aim of reaching the solution for the visual conflict as is often the case in situations when there is a clash between the existing objects and the newly designed or reconstructed object, This paper provides in-depth analysis of different types of bonds, such as 'direction as bond', 'cornice as bond', 'structure as bond', 'texture as bond' and 'material as bond', which indicate complexity and multiple layers of the designing process of object interpolation.

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

    Energy Technology Data Exchange (ETDEWEB)

    Swenson, E.R.

    1986-06-01

    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.

    2017-02-01

    As with many historical buildings around the world, building façades are of special interest; moreover, the details of such windows, stonework, and ornaments give each historic building its individual character. Each object of these buildings must be classified in an architectural object library. Recently, a number of researches have been focusing on this topic in Europe and Canada. From this standpoint, the Hijazi Architectural Objects Library (HAOL) has reproduced Hijazi elements as 3D computer models, which are modelled using a Revit Family (RFA). The HAOL will be dependent on the image survey and point cloud data. The Hijazi Object such as Roshan and Mashrabiyah, become as vocabulary of many Islamic cities in the Hijazi region such as Jeddah in Saudi Arabia, and even for a number of Islamic historic cities such as Istanbul and Cairo. These architectural vocabularies are the main cause of the beauty of these heritage. However, there is a big gap in both the Islamic architectural library and the Hijazi architectural library to provide these unique elements. Besides, both Islamic and Hijazi architecture contains a huge amount of information which has not yet been digitally classified according to period and styles. Due to this issue, this paper will be focusing on developing of Heritage BIM (HBIM) standards and the HAOL library to reduce the cost and the delivering time for heritage and new projects that involve in Hijazi architectural styles. Through this paper, the fundamentals of Hijazi architecture informatics will be provided via developing framework for HBIM models and standards. This framework will provide schema and critical information, for example, classifying the different shapes, models, and forms of structure, construction, and ornamentation of Hijazi architecture in order to digitalize parametric building identity.

  1. 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.

    To determine if pain relief provided by a wearable heat wrap (continuous, low-level, topical heat therapy) is superior to oral acetaminophen for primary dysmenorrhea. A randomized, active-controlled, multisite, single-blind (investigator), parallel-design study compared an abdominal wrap to an oral medication (acetaminophen, 1000 mg) over I day. Pain relief (0-5) and abdominal muscle tightness/cramping (0-100) were recorded at 12 time points. At 24 and 48 hours, menstrual symptom-based quality of life was assessed. Three hundred sixty-seven subjects entered the study, with 344 subjects evaluable. The heat wrap was superior to acetaminophen for pain relief over an 8-hour period (means of 2.48 and 2.17, p = 0.015) and at t hours 3, 4, 5 and 6 (p means of 40.4 and 44.5, p = 0.04) and at hours 4, 5 and 6 (p lower abdominal cramping (p < or = 0.05) with heat therapy. Continuous, low-level, topical heat therapy was superior to acetaminophen for the treatment of dysmenorrhea.

    Full Text Available Since the abrogation of Presidential Instruction Number 14/1967 which banned Chinese customs celebrations and religion in public, there has been a revival in Chinese festivals, language, art, media, culture and not in the least in the field of architecture and urban planning. With increasing interest in heritage and the support of the Indonesian government for heritage cities programmes, several promising initiatives involving Chinese architecture have been launched in cities both large and small. A brief glance of the history of Chinese Indonesian architecture is given, as well as some recent initiatives in selected cities plus a discussion of the importance of public space in accommodating Chinese festivals. Study of old maps and photographs prompts reflections on the characteristics and development of Pecinan during the colonial era and of their later history. The analysis in this article and examples of recent developments in the cities discussed can be used as an inspiration in the revitalization of Pecinan, thereby contributing in an attractive and livable urban environment.

    The aim of this study was to develop nanoemulsion containing soft extract of stem bark of Rapanea ferruginea to improve the topical delivery and anti-inflammatory activity. 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. PMID:27660442

    Topical chemotherapy is the application of cancer drugs directly onto the skin, which has become a standard treatment for basal cell carcinoma. Due to the promising results in the treatment of skin cancer, topical chemotherapy has recently been applied to breast cancer patients because some breast cancer tissues are only superficial. Hydroxytyrosol, a phenolic compound from olives that is present in high amounts in Hidrox(®) olive extract, has been shown to have a protective effect on normal cells and selective antitumor activities on cancerous cells. The aims of the present study were to develop an alginate bilayer film containing Hidrox(®) and to investigate its potential use as a topical chemotherapeutic agent. Alginate films were characterized for swelling and for physical, thermal, rheological, and mechanical properties. Drug content uniformity and in vitro drug release tests were also investigated. The alginate bilayer films containing Hidrox(®), HB2, showed controlled release of hydroxytyrosol at a flux of 0.094±0.009 mg/cm(2)/h. The results of the cytotoxic assay showed that the HB2 films were dose-dependent and could significantly reduce the growth of breast cancer cells (MCF-7) at 150 μg/mL for a cell viability of 29.34±4.64%. In conclusion, an alginate bilayer film containing Hidrox(®) can be a potential alternative for topical chemotherapeutic agent for skin and breast cancer treatment.

    2012-12-01

    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.

  19. 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...

  3. Misselling as a New Topic of Financial Education? A Didactic Analysis of Investment Advise after the Financial Crisis

    Directory of Open Access Journals (Sweden)

    Dirk Loerwald

    2010-07-01

    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.

    2013-11-30

    Rutin, the glycoside of quercetin, could be used in topical preparations because of its antioxidant and radical scavenging properties, but its employ in cosmetic and pharmaceutical products is limited by poor physico-chemical stability. These issues were addressed by preparing, characterizing and testing rutin inclusion complexes with MCM-41 mesoporous silica. The effect of surface functionalization with aminopropyl groups (NH₂-MCM-41) on the molecules properties was studied. The organic/inorganic interaction was confirmed by many techniques. In particular, the high inclusion of rutin in the pores of NH₂-MCM-41 was assessed by XRD, TGA, gas-volumetric analysis (BET), while FTIR spectroscopy allowed to analyse with great detail the molecular interaction with the inorganic surface. Rutin was stabilized against UV degradation, mostly by its inclusion in NH₂-MCM-41. Ex vivo studies showed a greater accumulation in porcine skin in the case of rutin complexed with NH₂-MCM-41. Not only antioxidant properties of rutin were maintained after immobilization but, with aminopropyl silica, the metal-chelating activity increased noticeably. The immobilization of rutin in aminopropyl silica resulted in better performance in terms of activity and photostability, suggesting the importance of functionalization in stabilizing organic molecules within silica pores.

    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 episiotomy wound care with little or no expected side effects compared with that using placebo.

    This article argues that Kurmuk, a little-described Western Nilotic language, is characterized by a syntacticized topic whose grammatical relation is variable. In this language, declarative clauses have as topic an obligatory preverbal NP which is either a subject, an object or an adjunct....... The grammatical relation of the topic is expressed by a voice-like inflection of the verb, here called orientation. While subject-orientation is morphologically unmarked, object-oriented and adjunct-oriented verbs are marked by a subject suffix or by a suffix indicating that the topic is not subject, and adjunct......-orientation differs from object-orientation by a marked tone pattern. Topic choice largely reflects information structure by indicating topic continuity. The topic also plays a crucial role in relative clauses and in clauses with contrastive constituent focus, in that objects and adjuncts can only be relativized...

    Full Text Available Michael A Page, Frederick W FraunfelderDepartment of Ophthalmology (Casey Eye Institute, Oregon Health and Science University, Portland, OR, USAPurpose: To review the current literature on safety, efficacy, and measures of surgeon and patient satisfaction with lidocaine hydrochloride gel as a tool for ocular anesthesia.Methods: Pubmed search using keywords “lidocaine gel,” “ophthalmic,” and “surgery” and compiling cross-references. Twenty-six total references were reviewed, including 15 prospective randomized controlled trials (RCTs, total N = 933, average N = 62, 6 nonrandomized prospective studies (total N = 234, average N = 39, 2 animal studies, 1 microbiologic study, and 2 letters to the editor.Results: The RCTs and nonrandomized prospective studies evaluated a number of measures including timing of onset of anesthesia, duration of anesthesia, intraoperative and postoperative pain, need for additional anesthetic applications, intracameral lidocaine levels, and adverse effects. Control groups received topical drops, subconjunctival anesthetic, retrobulbar anesthetic, or sham gel. Lidocaine gel was shown to be at least as effective for pain control as alternative therapies in all studies, with longer duration of action than topical drops. Patient and surgeon satisfaction were high, and adverse effects were rare and comparable to those for anesthetic drop formulations. Surgical settings included cataract, pterygium, trabeculectomy, strabismus, intravitreal injection, vitrectomy, and penetrating keratoplasty.Conclusions: Lidocaine gel is a safe, effective, and potentially underutilized tool for ophthalmic surgery.Keywords: lidocaine, gel, topical, ophthalmic, ocular, anesthetic

    In the context of development of the agriculture as the driver of the economy of Kazakhstan it is imperative to study new types of agrarian constructions (agroparks, agrotourists complexes, "vertical" farms, conservatories, greenhouses) that can be combined into complexes - agrarian technoparks. Creation of agrarian technoparks as elements of the infrastructure of the agglomeration shall ensure the breakthrough in the field of agrarian goods production, storing and recycling. Modeling of architectural-planning solutions of agrarian technoparks supports development of the theory and practice of designing objects based on innovative approaches.

  12. 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 topical application of antioxidants may be beneficial for the protection of the skin against UV damage. An extract of Quercus robur leaves was prepared and evaluated considering its putative application as topical antioxidant. The solvent and extractive method selection was monitored by 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical scavenging activity and polyphenols extraction (measured by the Folin Ciocalteu assay). Iron chelating activity and the phenolic composition (HPLC/DAD) were assessed on the extract obtained under optimized conditions. Skin irritation potential was investigated by performing an in vivo patch test in 19 volunteers. The extraction solvent which resulted in the highest activity was ethanol:water (4:6) and thus it was selected for further preparation of this extract. The IC50s for the iron chelation and DPPH scavenging assays were 153.8 +/- 26.3 microg x mL-1 and 7.53 +/- 0.71 microg x mL-1 (mean +/- SD), respectively. The total phenolic content was found to be 346.3 +/- 6.7 mg gallic acid equivalents (GAE)/g extract (mean +/- SD). Three phenolic compounds were identified in the extract namely: ellagic acid, rutin and hyperoside. The major identified component was ellagic acid. The patch test carried out showed that the extract can be regarded as safe for topical application.

    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.

    the 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...

  16. Infra-Free® (IF) Architecture System as the Method for Post-Disaster Shelter Model

    Science.gov (United States)

    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.

  19. The Emergence of Agent-Based Technology as an Architectural Component of Serious Games

    Science.gov (United States)

    Phillips, Mark; Scolaro, Jackie; Scolaro, Daniel

    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).

  20. Architecture as animate landscape: circular shrines in the ancient Maya lowlands.

    Science.gov (United States)

    Harrison-Buck, Eleanor

    2012-01-01

    In this study, I develop a theory of landscape archaeology that incorporates the concept of “animism” as a cognitive approach. Current trends in anthropology are placing greater emphasis on indigenous perspectives, and in recent decades animism has seen a resurgence in anthropological theory. As a means of relating in (not to) one's world, animism is a mode of thought that has direct bearing on landscape archaeology. Yet, Americanist archaeologists have been slow to incorporate this concept as a component of landscape theory. I consider animism and Nurit Bird-David's (1999) theory of “relatedness” and how such perspectives might be expressed archaeologically in Mesoamerica. I examine the distribution of marine shells and cave formations that appear incorporated as architectural elements on ancient Maya circular shrine architecture. More than just “symbols” of sacred geography, I suggest these materials represent living entities that animate shrines through their ongoing relationships with human and other-than-human agents in the world.

In architectural theory the nineteenth century German architect Gottfried Semper...... is known for his writings on theatricality, understood as a holistic design approach emphasizing the contextual, cultural, ritual and social meanings rooted in architecture.

  4. [Topical therapy of rosacea].

    Science.gov (United States)

    Schöfer, H

    2013-07-01

    Metronidazole and azelaic acid are the only topical medications approved for rosacea. All other topical treatments for rosacea and its special forms are used off-label. Topical steroids are not indicated in rosacea, because of their side effects (induction of steroid rosacea, high risk of facial skin atrophy, and high risk of rebound after cessation of therapy). Topical as well as systemic steroids are allowed only as initial and short term therapy for acute forms of rosacea (e.g. rosacea fulminans). Papular and pustular rosacea is the major indication for topical therapy. Sebaceous gland and connective tissue hyperplasia in glandular-hypertrophic rosacea as well as erythema in erythematous rosacea do not respond well to topical measures. A new active substance, the alpha-2-adrenoreceptor agonist brimonidine, will be approved soon for the topical treatment of erythema in rosacea. All severe forms of rosacea should initially be treated with a combination of topical and systemic agents. After improvement of the clinical symptoms, topical treatment alone is usually adequate to maintain the control.

  7. The Wall as a Spatial Work: the Reliefs of Jorge Oteiza in Architecture (1951-58

    Directory of Open Access Journals (Sweden)

    Emma López Bahut

    2014-03-01

    Full Text Available This paper analyses the mural projects of Basque sculptor Jorge Oteiza on façades and internal walls between the years 1951-58. At first, he dealt with walls as ground planes on which to execute his sculptures, finally viewing them as an empty plane with spatial possibilities, defined by the minimum forms and the action of natural light. Based on original, previously unpublished material, we explore the evolution of this work with the aim of establishing to what extent this process was marked by the architecture on which his work was executed, by the architects with whom he collaborated, or the stage of his sculptural experimentation with which they are associated. We show that apart from the presence of an architect, there is a correlation between the way in which the reliefs were applied to the wall and the work carried out on the space where the project was created: the larger the spatial work on the wall, the greater the relationship with the space within which it was inserted, at every scale, from the interior of the architecture to the urban space.

    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”.

    2014-02-01

    Interstitial Cajal-like cells are a distinct type of interstitial cell with a wide distribution in mammalian organs and tissues, and have been given the name "telocytes". Recent studies have demonstrated the potential roles of telocytes in heart development, renewal, and repair. However, further research on the functions of telocytes is limited by the complicated in vivo environment. This study was designed to construct engineered heart tissue (EHT) as a three-dimensional model in vitro to better understand the role of telocytes in the architectural organization of the myocardium. EHTs were constructed by seeding neonatal cardiomyocytes in collagen/Matrigel scaffolds followed by culture under persistent static stretch. Telocytes in EHTs were identified by histology, toluidine blue staining, immunofluorescence, and transmission electron microscopy. The results from histology and toluidine blue staining demonstrated widespread putative telocytes with compact toluidine blue-stained nuclei, which were located around cardiomyocytes. Prolongations from the cell bodies showed a characteristic dichotomous branching pattern and formed networks in EHTs. Immunofluorescence revealed positive staining of telocytes for CD34 and vimentin with typical moniliform prolongations. A series of electron microscopy images further showed that typical telocytes embraced the cardiomyocytes with their long prolongations and exhibited a marked appearance of nursing cardiomyocytes during the construction of EHTs. This finding highlights the great importance of telocytes in the architectural organization of EHTs. It also suggests that EHT is an appropriate physical and pathological model system in vitro to study the roles of telocytes during heart development and regeneration.

  11. Choice Architecture as a Way to Encourage a Whole Systems Design Perspective for More Sustainable Infrastructure

    Directory of Open Access Journals (Sweden)

    Nora Harris

    2016-12-01

    Full Text Available Across fields, more sustainable and resilient outcomes are being realized through a whole systems design perspective, which guides decision-makers to consider the entire system affected including interdependent physical and social networks. Although infrastructure is extremely interdependent, consisting of diverse stakeholders and networks, the infrastructure design and construction process is often fragmented. This fragmentation can result in unnecessary tradeoffs, leading to poor outcomes for certain stakeholders and the surrounding environment. A whole systems design perspective would help connect this fragmented industry and lead to more sustainable outcomes. For example, a whole systems design approach to relieve traffic on a highway might see beyond the obvious, but often ineffective, response of adding a new vehicle lane to encourage a solution such as repurposing existing road lanes from automobiles to above-ground “subway” systems. This paper discusses influences to whole systems design and how intentional choice architecture, meaning the way decisions are posed, can nudge decision-makers to employ whole systems design and result in more sustainable infrastructure. By uncovering these influences and organizing them by the social, organizational, and individual levels of the infrastructure design process, this paper provides the needed foundation for interdisciplinary research to help harness these influences through choice architecture and whole systems design for the infrastructure industry.

  12. Art as behaviour--an ethological approach to visual and verbal art, music and architecture.

    Science.gov (United States)

    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 The Bushehr city (Iran had been the center of attention in different historical periods by foreign countries and central government due to political and economic strategic position in Persian Gulf. The situation and condition of Bushehr, especially in Qajar era, caused that the city encountered the changes and reformations as a result of both inner and outer factors. So, the modernism process occurred in this city not long after it had emerged in Europe. So that, some buildings were built in the city which contained the features of modernism. This research, at first, introduces the former consulate of Britain (Sabzabad edifice and discovers when the building was built based on a historical-interpretative method. After that, the principals of modern architecture are explained from the different theorists’ stand point and also the characteristics of early modern architecture in Iran are explained. Finally, by describing the Bushehr condition in the early arrival of modernism, a qualitative and adaptive comparison has been done between Sabzabad architectural mechanism and the principals of modern architecture and its features in Iran. Thus, Sabzabad edifice is regarded as one of the first samples of modern architecture in Iran. The results of this research demonstrate the political, economic and also the architectural status of Bushehr city in the process of modernism in Iran which has been neglected by researchers and historians thus far.

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 aim was to investigate systemic exposure after administration of a novel bupivacaine lozenge in healthy individuals with normal mucosa and in head and neck cancer (HNC) patients with oral mucositis. A lozenge containing 5, 10, 25 and 50 mg bupivacaine, respectively, was administered as single dose to 10 healthy individuals, and a lozenge containing 25 mg bupivacaine was administered as single dose to 10 HNC patients with oral mucositis and as multiple doses to five patients with HNC. Blood samples were collected for 6 hr from the healthy individuals and 3 hr from the patients with HNC, respectively, after administration. The plasma concentration-time profiles of bupivacaine were fitted to pharmacokinetic models using nonlinear mixed-effects modelling, evaluating demographics and health status as covariates. The population pharmacokinetics (PK) of bupivacaine lozenge was best described by a two-compartment distribution model with absorption transit compartments. All the observed plasma concentrations were well below the bupivacaine concentrations (2000-2250 ng/ml) which have caused toxic symptoms. The PK model suggested that relative bioavailability was two times higher in HNC patients with oral mucositis grade 1-2 and three times higher in HNC patients with oral mucositis grade 3-4 than in the healthy individuals. Simulations showed that the plasma concentrations would be below the toxic limit after repeated dosing every second hour with 25 mg bupivacaine for five days. The 25-mg bupivacaine lozenges were safe without systemic toxic levels of bupivacaine or risk of side effects. Based on PK simulations of repeated doses of 25 mg every two hours for 16 hr a day, the lozenges can be administered with minimum risk of exceeding the toxic limit.

    The main objective of this study was to develop reversed hexagonal (HII) mesophase for transdermal delivery of methyl salicylate. The formulation was prepared, characterized and evaluated for its skin penetration in vitro and skin retention in vivo. Preliminary pharmacodynamics and skin irritation were also investigated. The formulation was identified as hexagonal structure. In vitro study exhibited that HII mesophase enhanced the skin permeation by delivering 2.61 times more methyl salicylate than the commercially available cream. Meanwhile, HII mesophase presented higher bioavailability as AUC(0-24) and AUC(0-∞) were 32.894μg·mL(-1) and 32.935μg·mL(-1) respectively, while the cream were 12.791μg·mL(-1) and 12.970μg·mL(-1). Preliminary pharmacodynamics studies demonstrated that HII mesophase possessed anti-inflammatory and analgesic effects for inhibiting paw edema, granuloma and pain. MeSa HII mesophase showed no skin irritation on the normal rat skin. Thus, HII mesophase was considered as an effective delivery system for MeSa.

    Even though the synthetic preservatives may offer a high antimicrobial efficacy, they are commonly related to adverse reactions and regarded as having potentially harmful effects caused by chronic consumption. The development of natural preservatives provides a way of reducing the amount of synthetic preservatives normally used in pharmaceutical and cosmetic preparations. In addition, these agents have less toxic effects and represent a possible natural and safer alternative of the preservatives. The purpose of this research was to evaluate the Rubus rosaefolius Smith extract efficiency as a natural preservative in base formulations. Of the extract, 0.2% (w/w) was assayed for its effectiveness of antimicrobial protection in two different base formulations (emulsion and gel). The microbial challenge test was performed following the standard procedures proposed by The United States Pharmacopoeia 33nd, European Pharmacopoeia 6th, Japanese Pharmacopoeia 15th, and the Cosmetics, Toiletries, and Fragrance Association using standardized microorganisms. The results demonstrated that R. rosaefolius extract at the studied concentration reduced the bacterial inocula, satisfying the criterion in all formulations, even though it was not able to present an effective preservative behavior against fungi. Thus, the investigation of new natural substances with preservative properties that could be applied in pharmaceutical and cosmetic products is relevant due to the possibility of substituting or decreasing the concentration of synthetic preservatives, providing a way for the development of safer formulas for the use of consumers.

    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.

    Objective To illustrate adolescent self-regulation as a foundation for both individual and interpersonal processes in adolescent chronic illness self-management. Method Literature review. Results Research has identified multiple individual (e.g., self-efficacy, coping, and adherence) and interpersonal factors (parental monitoring and friend support) that are sources of risk and resilience to adolescent chronic illness self-management. In this article, we highlight literature consistent with the idea that self-regulation (including cognitive, emotional, and behavioral regulation) underlies both individual and interpersonal sources of risk and resilience across development. Conclusions This self-regulation approach has multiple benefits: A parsimonious construct for explaining both individual and interpersonal processes that contribute to risk and resilience for chronic illness self-management, the incorporation of methods used in developmental and health psychology research, including performance-based, physiological, daily, and ecological momentary assessment, and a new look to interventions that target self-regulation as a way to improve individual and interpersonal processes in chronic illness self-management.

    Propylene glycol (PG)-phospholipid vesicles have been advocated as flexible lipid vesicles for enhanced skin delivery of drugs. To further characterize the performance of these vesicles and to address some relevant pharmaceutical issues, miconazole nitrate(MN)-loaded PG nanoliposomes were prepared and characterized for vesicle size, entrapment efficiency, in vitro release, and vesicle stability. An issue of pharmaceutical importance is the time-dependent, dilution-driven diffusion of propylene glycol out of the vesicles. This was addressed by assessing propylene glycol using gas chromatography in the separated vesicles and monitoring its buildup in the medium after repeated dispersion of separated vesicles in fresh medium. Further, the antifungal activity of liposomal formulations under study was assessed using Candida albicans, and their in vitro skin permeation and retention were studied using human skin. At all instances, blank and drug-loaded conventional liposomes were included for comparison. The results provided evidence of controlled MN delivery, constant percent PG uptake in the vesicles (≈45.5%) in the PG concentration range 2.5 to 10%, improved vesicle stability, and enhanced skin deposition of MN with minimum skin permeation. These are key issues for different formulation and performance aspects of propylene glycol-phospholipid vesicles.

    The basic properties and the in vitro release rate kinetics of azelaic acid (AA), alternatively vehiculated in different phospholipid-based vesicles such as ethosomes or liposomes, were investigated. Ethosomes were produced by a simple method based on addition of an aqueous phase to an ethanol solution (comprised between 20\\% and 45%, v/v) of soy phosphatidyl choline (5%, w/w) and AA (0.2%, w/w) under mechanical stirring. Liposomes were obtained by the same composition in the absence of ethanol with the reverse-phase evaporation method. Vesicle size was measured by photon correlation spectroscopy (PCS), evidencing smaller mean diameters and narrower dimensional distributions in the case of ethosomes with respect to liposomes. In order to obtain homogeneously sized vesicles, both ethosomal and liposomal dispersions were extruded through polycarbonate membranes with pores of calibrated diameter (400 nm and 200 nm). Vesicle morphology was characterized by freeze-fracture scanning electron microscopy (SEM) showing the presence of unilamellar vesicles both in liposome- and in ethosome-based dispersions. Free energy measurements of the vesicle bilayers were conducted by differential scanning calorimetry (DSC). AA diffusion from ethosomal or liposomal dispersions and from ethosomes and liposomes incorporated in a viscous gel was investigated by a Franz cell assembled with synthetic membranes. The release rate was more rapid from ethosomal systems than from liposomal systems. In particular, ethosomes produced by the highest ethanol concentration released AA more rapidly, and the same trend was found using viscous forms.

    TXA497 is representative of a new class of guanidinomethyl biaryl compounds that exhibit potent bactericidal behavior against methicillin-resistant Staphylococcus aureus (MRSA). In this study, we compared the anti-staphylococcal, skin deposition, and skin permeation properties of TXA497 and the topical anti-MRSA antibiotic mupirocin. The results of minimum inhibitory concentration (MIC) assays revealed that TXA497 retains potent activity against MRSA that is highly resistant to mupirocin. Using Franz diffusion cells, compound deposition into human cadaver skin was evaluated, and the results showed the skin deposition of TXA497 to be significantly greater than that of mupirocin. Moreover, unlike mupirocin, TXA497 does not pass through the entire skin layer, suggesting a minimal potential for the systemic absorption of the compound upon topical administration. Additionally, antibacterial concentrations of TXA497 showed no significant toxicity to primary human keratinocytes. Given the rising levels of mupirocin resistance among MRSA populations, our results are significant in that they highlight TXA497 as a potentially useful alternative therapy for treating MRSA skin infections that are resistant to mupirocin.

  5. Exploring the Abyss. The Financial Crisis of 2008 ff. as a Central Topic of Problem-Centered Social Science Education

    Directory of Open Access Journals (Sweden)

    Thorsten Hippe

    2010-07-01

    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.

    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.

  7. Topics in quantum foundations: Ontological models, and distinguishability as a resource

    Science.gov (United States)

    Morris, Ryan

    This thesis covers research in two disjoint research areas: The ontological model program (formerly hidden-variables program) for quantum theory has a long and noble tradition in the quantum foundations literature. By postulating a physical reality beyond the quantum state, we gain intuition on quantum phenomena and also come to understand constraints on realist interpretations of quantum theory. Bell's theorem tells us that such an underlying reality must be non-local, while the Kochen-Specker contextuality theorem abuses the classical notion that measurement should simply reveal pre-existing properties of reality. Recent research programs suggest that it is beneficial to view the quantum state as representing purely information. We show that the only current model which does this in a satisfactory manner is unable to reproduce all the statistics of quantum measurements. A recent generalization of the notion of contextuality has allowed for proofs of contextuality which differ from the original Kochen-Specker notion. We add a new result which shows that measurements in a model where the quantum state represents information must be contextual. Additionally, we refine the generalized notion of contextuality into strong and weak forms in order to parse the relationship between new and old results. Entanglement resource theory is a highly successful investigation of the usefulness of entanglement for information processing tasks. In this thesis we apply the ideas from entanglement resource theory to another resource: state distinguishability. We show analogies between distinguishability resource theory and entanglement resource theory. In particular, the analogy includes: measures which are monotonic under a class of transformations; units of a resource; and bounds on measures in terms of the amount of the unit resource needed to form states and the amount of unit resource that can be extracted from states. We show that the pairs of states which can be reversibly

  9. Urban Architecture as Connective-Collective Intelligence. Which Spaces of Interaction?

    Directory of Open Access Journals (Sweden)

    Marco Simonetti

    2013-07-01

    Full Text Available During the twentieth century, with the advent of industrial society and globalization, the language of planning changed according to the shifts in construction and use of physical space. By borrowing terms and spatial forms from biology and cybernetics, industrial society and globalization increased the original semantic connotations. Moving from cognitive sciences, this paper outlines the definition of architecture as connective-collective intelligence and presents its implication in urban design. Spontaneous and commercial initiatives are redefining the communication form of urban life, affecting the procedures of the transmission of traditional knowledge. This approach to building environment is moving towards a complex multichannel interaction, involving both the individual and the collective experiences of space and technology. In describing some signs of that process, the authors outline new features that are changing the concept of sustainability in urban design.

  10. Superficial keratectomy and topical mitomycin C as therapy for a corneal squamous cell carcinoma in a dog.

    Karasawa, K; Matsuda, H; Tanaka, A

    2008-04-01

    A 10-year-old female West Highland white terrier was presented with refractory hyperplastic keratitis of the left cornea of one month's duration. At this time, a vascularised and rough lesion 5 mm in diameter was observed on the left cornea. No other abnormality was recognised on the affected eye. The corneal neoplasm was surgically removed and histologically diagnosed as a squamous cell carcinoma. For two months after the surgery, 0.04 percent mitomycin C (MMC) eye drops were applied as adjuvant chemotherapy. Primary corneal squamous cell carcinoma with no history of keratoconjunctivitis sicca is rare in dogs. In the present report, surgical removal of the neoplasm was combined with the topical administration of the anticancer drug mitomycin C and a good prognosis was obtained. The result indicates that the combination treatment used in this case may be an appropriate therapeutic choice for corneal squamous cell carcinoma in dogs.

    2010-09-01

    The abdominal wall is a composite of muscles that are important for the mechanical stability of the spine and pelvis. Tremendous clinical attention is given to these muscles, yet little is known about how they function in isolation or how they interact with one another. Given the morphological, vascular, and innervation complexities associated with these muscles and their proximity to the internal organs, an appropriate animal model is important for understanding their physiological and mechanical significance during function. To determine the extent to which the rat abdominal wall resembles that of human, 10 adult male Sprague-Dawley rats were killed and formalin-fixed for architectural and morphological analyses of the four abdominal wall muscles (rectus abdominis, external oblique, internal oblique, and transversus abdominis). Physiological cross-sectional areas and optimal fascicle lengths demonstrated a pattern that was similar to human abdominal wall muscles. In addition, sarcomere lengths measured in the neutral spine posture were similar to human in their relation to optimal sarcomere length. These data indicate that the force-generating and length change capabilities of these muscles, relative to one another, are similar in rat and human. Finally, the fiber lines of action of each abdominal muscle were similar to human over most of the abdominal wall. The main exception was in the lower abdominal region (inferior to the pelvic crest), where the external oblique becomes aponeurotic in human but continues as muscle fibers into its pelvic insertion in the rat. We conclude that, based on the morphology and architecture of the abdominal wall muscles, the adult male Sprague-Dawley rat is a good candidate for a model representation of human, particularly in the middle and upper abdominal wall regions.

    2014-06-01

    The Night Vision Image Generator (NVIG), a product of US Army RDECOM CERDEC NVESD, is a visualization tool used widely throughout Army simulation environments to provide fully attributed synthesized, full motion video using physics-based sensor and environmental effects. The NVIG relies heavily on contemporary hardware-based acceleration and GPU processing techniques, which push the envelope of both enterprise and commodity-level hypervisor support for providing virtual machines with direct access to hardware resources. The NVIG has successfully been integrated into fully virtual environments where system architectures leverage cloudbased technologies to various extents in order to streamline infrastructure and service management. This paper details the challenges presented to engineers seeking to migrate GPU-bound processes, such as the NVIG, to virtual machines and, ultimately, Cloud-Based IAS architectures. In addition, it presents the path that led to success for the NVIG. A brief overview of Cloud-Based infrastructure management tool sets is provided, and several virtual desktop solutions are outlined. A discrimination is made between general purpose virtual desktop technologies compared to technologies that expose GPU-specific capabilities, including direct rendering and hard ware-based video encoding. Candidate hypervisor/virtual machine configurations that nominally satisfy the virtualized hardware-level GPU requirements of the NVIG are presented , and each is subsequently reviewed in light of its implications on higher-level Cloud management techniques. Implementation details are included from the hardware level, through the operating system, to the 3D graphics APls required by the NVIG and similar GPU-bound tools.

  13. Urban-architectural workshop as an opportunity for theoretical reflection: Example of the international urban-architectural workshop Maribor-South

    Directory of Open Access Journals (Sweden)

    Peter Šenk

    2013-07-01

    Full Text Available The paper presents the international urban-architectural workshop Maribor-South (2010-11 as a model for “Maribor’s” urban-architectural workshops, which urban planners evaluate and use to direct urban development and theoretical discussion. The presented interdisciplinary project explored possibilities for designing the southern edge of the city in the area where the southern bypass construction is planned. In addition describing the example of the workshop, which develops the theoretical field through a “practical and project approach” with the defined project basis, i.e. the defined area of discussion and project issue, the paper also highlights the opportunity for a “theoretical approach”. The theoretical approach aims at providing a wider insight into the related theoretical field based on a generalised spatial issue. As one of the key priorities of contemporary urban planning and sustainable urban redevelopment, the planned direction of urban development in the areas of constructing transport infrastructure, which is evident in the first approach, moves into a wider referential field (no longer directly related to the project with the second approach by examining the issues of mobility, space, place, diversity of infrastructures of contemporary space, etc. While in the first approach developing design concepts strives for theoretical conceptualisation, the second approach facilitates focusing on finding links between the theoretical concept and manifestations in real space, though the approaches are always separated. Their operationality is possible only on the level of “combinatorial thinking” and remains beyond direct instrumentality.

  14. Place-Based Education in the Architectural Design Studio: Agrarian Landscape as a Resource for Sustainable Urban Lifestyle

    Directory of Open Access Journals (Sweden)

    Ana Nikezić

    2015-07-01

    Full Text Available This article highlights how “place-based education” can be used to raise awareness about sustainability and potentially influence design process decisions that have environmental and cultural implications. “Place-based education” is a term used to describe an educational worldview based on development of curriculum centered on the local, social, economic, and ecological resources of a community. The study shows results of Masters Students’ research on situating a housing complex in the context of the agrarian landscape of Vojvodina, Serbia, considering it as a resource for a new sustainable urban lifestyle. During the first year of Masters Studies at the Faculty of Architecture, Belgrade University, an architectural design studio with 15 students had the task of exploring the potential of expanding the city of Belgrade across the agrarian landscape, as to affirm the role of place in contemporary everyday life. Students were expected to explore the possibilities and limitations of the relationship between man and agrarian landscape via architecture, re-thinking how various architectural design approaches could balance and harmonize the impact of the built environment on the agrarian landscape. The paper shows that “place-based education” possesses elements necessary for the inclusion of a wider spatial-cultural context in the process of architectural design and prioritization of environmental literacy and responsibility, as one of the main components of sustainable development.

    Oropharyngeal candidiasis (OPC) is caused by the opportunistic fungi Candida albicans and is prevalent in immunocompromised patients, individuals with dry mouth, or patients with prolonged antibiotic therapies that reduce oral commensal bacteria. Human salivary histatins, including histatin 5 (Hst 5), are small cationic proteins that are the major source of fungicidal activity of saliva. However, Hsts are rapidly degraded in vivo, limiting their usefulness as therapeutic agents despite their lack of toxicity. We constructed a conjugate peptide using spermidine (Spd) linked to the active fragment of Hst 5 (Hst 54-15), based upon our findings that C. albicans spermidine transporters are required for Hst 5 uptake and fungicidal activity. We found that Hst 54-15-Spd was significantly more effective in killing C. albicans and Candida glabrata than Hst 5 alone in both planktonic and biofilm growth and that Hst 54-15-Spd retained high activity in both serum and saliva. Hst 54-15-Spd was not bactericidal against streptococcal oral commensal bacteria and had no hemolytic activity. We tested the effectiveness of Hst 54-15-Spd in vivo by topical application to tongue surfaces of immunocompromised mice with OPC. Mice treated with Hst 54-15-Spd had significant clearance of candidal tongue lesions macroscopically, which was confirmed by a 3- to 5-log fold reduction of C. albicans colonies recovered from tongue tissues. Hst 54-15-Spd conjugates are a new class of peptide-based drugs with high selectivity for fungi and potential as topical therapeutic agents for oral candidiasis.

    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

    2016-07-01

    In early autumn, pupal cases of the scarce caddisfly species, Annitella amelia Sipahiler, 1998 were collected on the shore of a narrow, shallow brook from the northwestern Iberian peninsula, in Spain. Some of the pupal cases had been built as a new tube inside an existing tubular case. Moreover, for pupation, the last instar larvae clearly changed the architecture of the cases by adding internal and/or external grains of substrate at the tips. An architectural study with microCT techniques made it possible to divide each case into equal halves and to indirectly measure the weight of each. As no significant differences were found, it was concluded that pupa equilibrates its case, ensuring that it will lie horizontally on the substrate of the brook and thus avoid more vertical positions that might risk air exposure. The architectural changes could represent a survival strategy during pupation, in which the pupae remain in shallow channels ditches of the small brooks. (Author)

  7. The fractal globule as a model of chromatin architecture in the cell.

    Science.gov (United States)

    Mirny, Leonid A

    2011-01-01

    The fractal globule is a compact polymer state that emerges during polymer condensation as a result of topological constraints which prevent one region of the chain from passing across another one. This long-lived intermediate state was introduced in 1988 (Grosberg et al. 1988) and has not been observed in experiments or simulations until recently (Lieberman-Aiden et al. 2009). Recent characterization of human chromatin using a novel chromosome conformational capture technique brought the fractal globule into the spotlight as a structural model of human chromosome on the scale of up to 10 Mb (Lieberman-Aiden et al. 2009). Here, we present the concept of the fractal globule, comparing it to other states of a polymer and focusing on its properties relevant for the biophysics of chromatin. We then discuss properties of the fractal globule that make it an attractive model for chromatin organization inside a cell. Next, we connect the fractal globule to recent studies that emphasize topological constraints as a primary factor driving formation of chromosomal territories. We discuss how theoretical predictions, made on the basis of the fractal globule model, can be tested experimentally. Finally, we discuss whether fractal globule architecture can be relevant for chromatin packing in other organisms such as yeast and bacteria.

    Full Text Available Rod-shaped TiO2 nanocrystals (TiO2 NRs, capped by oleic acid molecules (OLEA, were synthesized with controlled size, shape and surface chemistry by using colloidal routes. They were investigated for application as coating materials for preserving architectural stone of monumental and archaeological interest, in consideration of their self-cleaning and protection properties. For this purpose, two different deposition techniques, namely casting and dipping, were tested for the application of a nanocrystal dispersion on a defined stone type, as a relevant example of porous calcarenites, namely the Pietra Leccese, a building stone widely used in monuments and buildings of cultural and historic interest of the Apulia region (Italy. The physical properties of the stone surface were investigated before and after the treatment with the prepared nanostructured materials. In particular, colour, wettability, water transfer properties and stability of the coating were monitored as a function of time and of the application method. The self-cleaning properties of the TiO2 NRs coated surfaces were tested under simulated and real solar irradiation. The obtained results were discussed in the light of the specific surface chemistry and morphology of TiO2 NRs, demonstrating the effectiveness of TiO2 NRs as an active component in formulations for stone protection.

    2016-07-01

    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.

    Heterochrony is known as a developmental change in the timing or rate of ontogenetic events across phylogenetic lineages. It is a key concept synthesizing development into ecology and evolution to explore the mechanisms of how developmental processes impact on phenotypic novelties. A number of molecular experiments using contrasting organisms in developmental timing have identified specific genes involved in heterochronic variation. Beyond these classic approaches that can only identify single genes or pathways, quantitative models derived from current next-generation sequencing data serve as a more powerful tool to precisely capture heterochronic variation and systematically map a complete set of genes that contribute to heterochronic processes. In this opinion note, we discuss a computational framework of genetic mapping that can characterize heterochronic quantitative trait loci that determine the pattern and process of development. We propose a unifying model that charts the genetic architecture of heterochrony that perceives and responds to environmental perturbations and evolves over geologic time. The new model may potentially enhance our understanding of the adaptive value of heterochrony and its evolutionary origins, providing a useful context for designing new organisms that can best use future resources. © The Author 2017.

  19. Proteins with complex architecture as potential targets for drug design: a case study of Mycobacterium tuberculosis.

    Directory of Open Access Journals (Sweden)

    Bálint Mészáros

    2011-07-01

    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.

    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.

    Herein, we report on polymer-nanocomposites with brush-like architectures and evaluate their feasibility as an all-solid electrolyte matrix supporting Li(+)-ion conduction. Showcased as a first example in the domain of electrolyte research, the study probes several key factors, such as (i) core morphology, (ii) surface modifiers/functionality, (iii) grafting length, and (iv) density of the brushes, and determines their role on the overall electrochemical properties of these nanostructured organic-inorganic hybrids. Nanostructured titania was synthesized via wet-chemical approaches using either controlled hydrolysis or hydrothermal methods. Exercising suitable control on reaction parameters led to well-defined morphologies/phases, such as nanoparticles, nanospindles, nanourchins, nanorods or nanotubes, in either anatase, rutile or mixed forms. Covalent anchoring on titania nanostructures was achieved using dopamine, gallic acid and glycerol as small organic moieties. A one-pot process of priming the available surface functional groups postmodification with isocyanate chemistry was followed by grafting polyethylene glycol monomethyl ethers of desired chain lengths. Finally, complexation with lithium salt yielded electrolyte compositions where the ethylene oxide (EO) fractions aid in ion-solvation with ease. The synthesized materials were characterized in detail employing XRD, TEM, DRS-UV, FTIR, micro-Raman, TG-DTA and DSC at each stage to confirm the products and ascertain the physicochemical properties. Comprehensive evaluation using temperature-step electrochemical impedance spectroscopy (EIS) of these brush-like nanocomposites provided crucial leads toward establishing a plausible physical model for the system and understanding the mechanism of ion transport in these all-solid matrices. The preliminary results on ionic conductivity (σ) obtained for some of the compositions are estimated to be within the range of ∼10(-4) to 10(-5) S cm(-1) in the temperature

    The research is aimed to investigate how lesson analysis as teacher’s self-reflection changes the teacher’s lesson design on chemical equation topic. Lesson Analysis has been used as part of teacher training programs to improve teacher’s ability in analyzing their own lesson. The method used in this research is a qualitative method. The research starts from build lesson design, implementation lesson design to senior high school student, utilize lesson analysis to get information about the lesson, and revise lesson design. The revised lesson design from the first implementation applied to the second implementation, resulting in better design. This research use lesson analysis Hendayana&Hidayat framework. Video tapped and transcript are employed on each lesson. After first implementation, lesson analysis result shows that teacher-centered still dominating the learning because students are less active in discussion, so the part of lesson design must be revised. After second implementation, lesson analysis result shows that the learning already student-centered. Students are very active in discussion. But some part of learning design still must be revised. In general, lesson analysis was effective for teacher to reflect the lessons. Teacher can utilize lesson analysis any time to improve the next lesson design.

    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.

    In Japan, indications for opioid analgesics, once exclusively used as pain killers for patients suffering from malignant cancer, have been expanded for a wide range of pain. Herein we report a patient with opioid-induced delirium associated with the administration of buprenorphine patches that was well below the indicated therapeutic range limit. An 82-year-old woman was referred to us from an orthopaedic practitioner for uncontrollable behavioural problems apparently caused by the beginning of dementia; the patient had gradually developed disorientation, visual hallucinations, and delusions. Laboratory and imaging findings excluded common causes of delirium including Alzheimer's disease and diffuse Lewy body disease. Detailed questioning revealed that the patient's confused state appeared following a buprenorphine patch dose increase and subsequently disappeared after administration was stopped. Delirium has not been reported as a side-effect in clinical trials of buprenorphine patches. However, our findings in this case show that even topical opioids can precipitate the development of a delirious state in elderly patients.

  6. Theories of minimalism in architecture: When prologue becomes palimpsest

    Full Text Available This paper examines the modus and conditions of constituting and establishing architectural discourse on minimalism. One of the key topics in this discourse are historical line of development and the analysis of theoretical influences, which comprise connections of recent minimalism with the theorizations of various minimal, architectural and artistic, forms and concepts from the past. The paper shall particularly discuss those theoretical relations which, in a unitary way, link minimalism in architecture with its artistic nominal counterpart - minimal art. These are the relations founded on the basis of interpretative models on self-referentiality, phenomenological experience and contextualism, which are superficialy observed, common to both, artistic and architectural, minimalist discourses. It seems that in this constellation certain relations on the historical line of minimalism in architecture are questionable, while some other are overlooked. Precisely, posmodern fundamentalism is the architectural direction: 1 in which these three interpretations also existed; 2 from which architectural theorists retroactively appropriated many architects proclaiming them minimalists; 3 which establish identical relations with modern and postmodern theoretical and socio-historical contexts, as well as it will be done in minimalism. In spite of this, theoretical field of postmodern fundamentalism is surprisingly neglected in the discourse of minimalism in architecture. Instead of understanding postmodern fundamentalism as a kind of prologue to minimalism in architecture, it becomes an erased palimpsest over whom the different history of minimalism is rewriting, the history in which minimal art which occupies a central place.

    This paper summarizes a team project report produced during the Summer Space Program of the International Space University, held at Nasa-Ames Research Center (CA, USA) by 56 students from 15 countries. Chair of the team project was Rene Laufer. Facilitators were Alfonso Davila and Jhonny Zavaleta, and teacher associate supporting the team was Beatriz Gallardo. The human race has evolved, grown and expanded through the exploration of Earth. After initial steps on the Moon, our next challenge is to explore the solar system. Mars shows potential for both scientific discovery and future human settlement, and therefore represents a prime candidate for the next leap of human exploration. Such a bold endeavor will be a driver for an unprecedented worldwide cooperative effort and the catalyst for a new era of international, intercultural and interdisciplinary human relations. Scientific and technological progress will also accelerate as mankind is ushered into a new era of space exploration. Currently proposed Mars missions have identified a number of challenges such as high levels of radiation, harsh climate and limited launch windows. Recently discovered lava tubes on Mars present potential solutions to some of these issues, but raise a variety of intriguing new challenges. This paper reviews existing reference missions and identifies areas of further research essential for adapting mission architectures to utilize caves. Different mission scenarios are proposed and analyzed, with a number of different recommendations given. An analysis of the feasibility of using Martian lava tubes as habitation is given in another paper by the same authors at COSPAR 2010 F34 Technical Session. Literature suggests a low radiation environment within Martian caves, allowing for extended duration missions. The ACCESS Mars Team concludes that the use of lava tubes as human habitats will be more beneficial for human Mars exploration than currently proposed surface solutions.

    2012-08-01

    Full Text Available This study was shaped and developed regarding the existence of a relationship between spatial perception and lines as observed in primary school children. Perception, receiving a variety of approaches from different disciplines, is assessed in our study through a model based on what portion of the things remembered by thechild is spatial and what are the remembered parts or features of a familiar space. The study investigates Anıtkabir as a well-known architectural object which carries very distinct structures in terms of linear expression. The study aims at determining to what extent the formal expression of the space remembered by the child aftervisual perception through drawing matches the artistic development stages; schematic, dawning realism and pseudorealism. A literature review was carried out in order to constitute a basis for the fieldwork encompassing children from schematic, dawning realism and pseudorealism stages. The second step has been providing theoretical information concerning Anıtkabir to the student groups from Başyayla Primary Education School attending to 4th (schematic, 6th (dawningrealism and 8th (pseudorealism grades using various common methods (visits, media, teaching tools, etc. during 2009-2010 Education Year Fall Semester. Later the students were asked to put their perceptions in practice and the results were interpreted within the target parameters. This study asserts that the formation of space in memory as a result of visual perception are coded in view of the phaseoccupied by the child, personal differences, different styles of perception and spatial experiences and the drawings support the features of the phase occupied by the child.

    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.

    An innovative niosomal system made up of alpha,omega-hexadecyl-bis-(1-aza-18-crown-6) (Bola), Span 80 and cholesterol (2:5:2 molar ratio) was proposed as a topical delivery system for 5-fluorouracil (5-FU), largely used in the treatment of different forms of skin cancers. Bola-niosomes showed a mean size of approximately 400 nm, which were reduced to approximately 200 nm by a sonication procedure with a polydispersion index value of 0.1. Bola-niosomes showed a loading capacity of approximately 40% with respect to the amount of 5-FU added during the preparation. 5-FU-loaded bola-niosomes were tested on SKMEL-28 (human melanoma) and HaCaT (non-melanoma skin cancer with a specific mutations in the p53 tumor suppressor gene) to assess the cytotoxic activity with respect to the free drug. 5-FU-loaded bola-niosomes showed an improvement of the cytotoxic effect with respect to the free drug. Confocal laser scanning microscopy studies were carried out to evaluate both the extent and the time-dependent bola-niosome-cell interaction. The percutaneous permeation of 5-FU-loaded niosomes was evaluated by using human stratum corneum and epidermis membranes. Bola-niosomes provided an increase of the drug penetration of 8- and 4-folds with respect to a drug aqueous solution and to a mixture of empty bola-niosomes with a drug aqueous solution.

    The aim was to assess the efficacy of adding benzydamine (B) spray to standard treatment with a lidocaine (L) spray before upper gastrointestinal endoscopy (UGE) as a topical anaesthetic regimen. A total of 118 adult patients undergoing outpatient UGE were randomly assigned to receive L (n=44), LB (n=38) or B (n=36) before the procedure. The primary outcome was the patient tolerance score, which represents a summative evaluation of the taste of the anesthetic agent, the intensity of pharyngeal numbness, the amount of coughing or gagging and the degree of discomfort during oesophageal intubation. The median (min-max) patient tolerance scores were comparable between groups LB (10.5; range 5-12) and L (10; range 4-13) (p=0.235) and significantly lower in group B (7.5; range 3-12) (psore throat (4 [10.5%] vs 15 [34.1%], p=0.011) in LB compared to L. LB is not superior to L in terms of overall patient tolerance, but LB may be preferred over L in cases with difficult oesophageal intubation or a previous history of postprocedural sore throat.

    Solid lipid nanoparticles (SLN) were developed by using Precirol ATO 5 as the solid core of the particles for topical psoralen delivery. Nanostructured lipid carriers (NLC) consisting of Precirol and squalene, a liquid lipid, were also prepared for comparison. SLN and NLC showed respective mean particle sizes of approximately 300 and 200nm, respectively. Viscosity, polarity, and differential scanning calorimetry (DSC) studies were performed to characterize the physicochemical properties of the SLN and NLC. The viscosity of all nanoparticulate systems exhibited Newtonian behavior except the NLC with Tween 80 and soybean phospholipids as the emulsifiers (NLC-Tw). According to the DSC thermograms, the melting peak of Precirol shifted from 58 to 55 degrees C after incorporating squalene into the solid lipid cores (of NLC), which suggests defects in the crystalline lattice of the lipid cores and smaller particle sizes. Three psoralen derivatives for psoriasis treatments were loaded in SLN and NLC to examine their ability to permeate skin. The permeability of psoralens increased in the order of 8-methoxypsoralen (8-MOP)>5-methoxypsoralen (5-MOP)>4,5,8-trimethylpsoralen (TMP). Enhanced permeation and controlled release of psoralen delivery were both achieved using the NLC. The in vitro permeation results showed that NLC-Tw increased the 8-MOP flux 2.8 times over that of a conventional emulsion. Hyperproliferative or psoriasis-like skin produced by repeated strippings in the dorsal skin of nude mouse was also used as a permeation barrier. The results showed that the entrapment of 8-MOP in nanoparticulate systems could minimize the permeation differentiation between normal and hyperproliferative skin compared to the free drug in an aqueous control.

    Indigo naturalis is a Traditional Chinese Medicine (TCM) ingredient long-recognized as a therapy for several inflammatory conditions, including psoriasis. However, its mechanism is unknown due to lack of knowledge about the responsible chemical entity. We took a different approach to this challenge by investigating the molecular profile of Indigo naturalis treatment and impacted pathways. A randomized, double-blind, placebo-controlled clinical study was conducted using Indigo naturalis as topical monotherapy to treat moderate plaque psoriasis in a Chinese cohort (n = 24). Patients were treated with Indigo naturalis ointment (n = 16) or matched placebo (n = 8) twice daily for 8 weeks, with 1 week of follow-up. At week 8, significant improvements in Psoriasis Area and Severity Index (PASI) scores from baseline were observed in Indigo naturalis-treated patients (56.3% had 75% improvement [PASI 75] response) compared with placebo (0.0%). A gene expression signature of moderate psoriasis was established from baseline skin biopsies, which included the up-regulation of the interleukin (IL)-17 pathway as a key component; Indigo naturalis treatment resulted in most of these signature genes returning toward normal, including down-regulation of the IL-17 pathway. Using an in vitro keratinocyte assay, an IL-17-inhibitory effect was observed for tryptanthrin, a component of Indigo naturalis. This study demonstrated the clinical efficacy of Indigo naturalis in moderate psoriasis, and exemplified a novel experimental medicine approach to understand TCM targeting mechanisms. NCT01901705 .

  20. The Modernization Concept as an Integrative Framework for the Methodology of Studying Topical Issues in Russian History

    Directory of Open Access Journals (Sweden)

    Yuri N. Smirnov

    2016-10-01

    Full Text Available The article is devoted to a number of methodological and concrete historical questions raised in the monograph by Boris Mironov, “The Russian Empire: From Tradition to Modernity.” The monograph is based on the modernization concept. The variety of methods and techniques borrowed by the author from different scientific disciplines and schools, but which demonstrate their usefulness, provide a reason to call his approach “integrative.” Smirnov shares Mironov’s perspective on the possibility of determining the laws of Russia’s historical path, and on the positive prospects for Russia’s movement upon it. Particular attention is paid to how Mironov examines and interprets the course of Russian colonization, its influence on the internal processes in society in general, and on the fate of specific regions and the ethnic groups. In Mironov’s opinion, the inclusion of new lands in Russia has had generally beneficial effects for the country as a whole and for the people who inhabit it. Smirnov engages in a thought experiment in order to assess in how far Mironov’s conclusions are applicable to the southeast of Russia. The results prove the validity of the conclusions and their applicability to research of other colonized territories. The reviewer recognizes as valid the opinion that the economic reserves of serfdom had not been exhausted by the middle of the 19th century. The liberation of the peasants was caused by many factors, among which moral and cultural reasons were not in the last place. The imperial “Enlightened” bureaucracy became the leader of peasant and other reforms. The article expressed disagreement that the strengthening of the position of the nobility and their power over the peasants in the 18th century was determined by the decisive role of the guard in palace coups. Mironov’s book will stimulate new research and discussions on topical issues of Russian history.

    The current study was undertaken to assess safety of Pistacia lentiscus fruits fatty oil (PLFO) as a topical traditional remedy. A primary skin and eye irritation tests were conducted with New Zealand white rabbits to determine the potential for PLFO to produce irritation from a single application. In addition, a sub acute dermal toxicity study was performed on 18 NZW rabbits to evaluate possible adverse effect following application of PLFO for 28 days. Based on the results of the current study, PLFO is classified as slightly irritating to the skin and the eye of rabbits (Primary Irritation Index (P.I.I.) = 1.037; Ocular Irritation Index (O.I.I.) = 5.33 at 1 h). In the sub-acute toxicity test, PLFO produced neither mortality nor significant differences in the body and organ weights between control group and treated rabbits. However, a reversible irritant contact dermatitis was observed in the treated areas from the end of the second week of application until the end of experiment. This local phenomenon was accompanied by a significant skin thickening (P≤0.01) since the 12(th) day (ANOVA, F = 11, 07143, P = 0, 00765) which is confirmed with an inflammatory granuloma in histological study. Haematological analysis and blood chemistry values of the 2 groups showed no significant differences in any of the parameters examined. In summary, PLFO is minimally irritating to the eye and skin after a single exposure, but it may cause irritant contact dermatitis and a reversible thickening of skin after prolonged use.

    Full Text Available Owing to the period of intensive development in the last decade of XX century, architectural phenomenon called Minimalism in Architecture was remembered as the Style of the Nineties, which is characterized, morphologically speaking, by simplicity and formal reduction. Simultaneously with its development in practice, on a theoretical level several dominant interpretative models were able to establish themselves. The new millennium and time distance bring new problems; therefore this paper represents a discussion on specific theorization related to Minimalism in Architecture that can bear the designation of post scriptum, because their development starts after the constitutional period of architectural minimalist discourse. In XXI century theories, the problem of definition of minimalism remains important topic, approached by theorists through resolving on the axis: Modernism - Minimal Art - Postmodernism - Minimalism in Architecture. With regard to this, analyzed texts can be categorized in two groups: 1 texts of affirmative nature and historical-associative approach in which minimalism is identified with anything that is simple and reduced, in an idealizing manner, relied mostly on the existing hypotheses; 2 critically oriented texts, in which authors reconsider adequacy of the very term 'minimalism' in the context of architecture and take a metacritical attitude towards previous texts.

  3. Sculpture Versus Architecture?

    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

  4. Topical polyethylene glycol as a novel chemopreventive agent for oral cancer via targeting of epidermal growth factor response.

    Full Text Available Head and neck squamous cell carcinoma (HNSCC is a major cause of morbidity and mortality underscoring the need for safe and effective chemopreventive strategies. Targeting epidermal growth factor receptor (EGFR is attractive in that it is an early critical event in HNSCC pathogenesis. However, current agents lack efficacy or have unacceptable toxicity. Several groups have demonstrated that the over-the-counter medication, polyethylene glycol (PEG has remarkable chemopreventive efficacy against colon carcinogenesis. Importantly, we reported that this effect is mediated through EGFR internalization/degradation. In the current study, we investigated the chemopreventive efficacy of this agent against HNSCC, using both the well validated animal model 4-NQO (4-nitroquinoline 1-oxide rat model and cell culture with the human HNSCC cell line SCC-25. We demonstrated that daily topical application of 10% PEG-8000 in the oral cavity (tongue and cavity wall post 4NQO initiation resulted in a significant reduction in tumor burden (both, tumor size and tumors/tumor bearing rat without any evidence of toxicity. Immunohistochemical studies depicted decreased proliferation (number of Ki67-positive cells and reduced expression of EGFR and its downstream effectors cyclin D1 in the tongue mucosa of 4NQO-rats treated with PEG. We showed that EGFR was also markedly downregulated in SCC-25 cells by PEG-8000 with a concomitant induction of G1-S phase cell-cycle arrest, which was potentially mediated through upregulated p21(cip1/waf1. In conclusion, we demonstrate, for the first time, that PEG has promising efficacy and safety as a chemopreventive efficacy against oral carcinogenesis.

    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.

    2014-12-01

    Eccentric training for Achilles tendinosis (AT) has been reported to significantly improve patient symptoms. There has been no biomechanical explanation on the mechanism for specific rehabilitation technique. The purpose of this study was to determine changes in muscle architecture that occurred as a result of Achilles tendinosis injury and a subsequent eccentric rehabilitation program. Twenty-five patients (age, 53.3 ± 17.5 years) diagnosed with AT participated in 6 weeks of rehabilitation. Specific exercises for the ankle plantar flexors consisted of maximal load eccentric muscle action using 3 sets of 15 repetitions. Patients also completed a protocol for AT, which consisting of traditional rehabilitation. Medial gastrocnemius (GM) and lateral gastrocnemius (GL) muscle fascicle length and thickness were measured with ultrasound at 2-week intervals from initial treatment day to the end of 6 weeks of rehabilitation. Medial gastrocnemius fascicle length increased (45.1 ± 10.5 mm to 51.4 ± 10.5 mm; P = .22) between the initial day of rehabilitation and after 6 weeks of rehabilitation. But, GM thickness (16.3 ± 3.5 mm to 16.8 ± 2.0 mm), GL fascicle length (47.2 ± 10.0 mm to 47.1 ± 7.4 mm), and GL thickness (14.9 ± 5.2 mm to 14.4 ± 2.7 mm) did not change as a result of rehabilitation. A 6-week eccentric-biased exercise increased the GM muscle fascicle length by 12%, but GM thickness, GL fascicle length, and GL thickness did not change as a result of rehabilitation. Eccentric training for the treatment of AT is well recognized, but the mechanism of action has not been previously reported. A 6-week eccentric training protocol increased the GM muscle fascicle length by 12%, and this correlated with improvement in a validated patient outcome scoring system. Further study is warranted to determine a predictive relationship between improvement of GM fascicle length and outcome scores. Therapeutic, Level IV: Case series. © 2014 The Author(s).

    Martín-Gómez, César; Zapata, Omayra; Zuazua, Amaia; Villanueva, Sonia; Olaizola, Paula

    2014-03-01

    The aim of this innovative educational project is to encourage students' interest in one of the most underrated fields of architecture: building services. With this material students interact with real elements and thereby understand the relationship between facilities and the building. A set of three small technical cabinets is planned. They allow for comfortable use and movement inside the building, need minimum maintenance and are easily stored. The result is an alternative concept of a mobile laboratory called a 'technical cabinet', made up of three mobile units for fire safety, electricity and the heating/cooling system. The design, content and learning systems of the cabinets confirmed the validity of the initial concept during the first year of use. A protocol has also been developed for each of the technical cabinets so that the teaching experience may be of use in other Schools of Architecture.

    Full Text Available The profession of the architect today should redefined where it loses the image of the anachronistic artist-architect capable of solving the complex problems of contemporary multiethnic societies that manifest mostly in suburbs by using “their genius”. It will become increasingly more important that collective design, and not individual approaches, embrace not only professionals but also expand to new disciplines: architecture and design, fine arts and sculpture. Obviously, architecture is not an object to be observed, but a field of energy and relationships within which to learn to move. The privileged nature of the designer will be the readiness to learn to from other discipline and cultures, in a world where distances contract and everything seems to be only a step away.

    In this work, we investigate a potential usefulness of a topic model-based categorization of lung cancers as quantitative CT biomarkers for predicting the recurrence risk after curative resection. The elucidation of the subcategorization of a pulmonary nodule type in CT images is an important preliminary step towards developing the nodule managements that are specific to each patient. We categorize lung cancers by analyzing volumetric distributions of CT values within lung cancers via a topic model such as latent Dirichlet allocation. Through applying our scheme to 3D CT images of nonsmall- cell lung cancer (maximum lesion size of 3 cm) , we demonstrate the potential usefulness of the topic model-based categorization of lung cancers as quantitative CT biomarkers.

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

    Science.gov (United States)

    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.

    Human civilization and architecture have defined each other for over 5000 years on Earth. Even in the novel environment of space, persistent issues of human urbanism will eclipse, within a historically short time, the technical challenges of space settlement that dominate our current view. By adding modern topics in space engineering, planetology, life support, human factors, material invention, and conservation to their already renaissance array of expertise, urban designers can responsibly apply ancient, proven standards to the exciting new opportunities afforded by space. Inescapable facts about the Moon set real boundaries within which tenable lunar urbanism and its component architecture must eventually develop.

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

    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.

    Topical therapy is the first choice for the treatment of mild to moderate acne and all-trans retinoic acid is one of the most used drugs. The combination of retinoids and antimicrobials is an innovative approach for acne therapy. Recently, lauric acid, a saturated fatty acid, has shown strong antimicrobial activity against Propionibacterium acnes. However, topical application of retinoic acid is followed by high incidence of side-effects, including erythema and irritation. Solid lipid nanoparticles represent an alternative to overcome these side-effects. This work aims to develop solid lipid nanoparticles loaded with retinoic acid and lauric acid and evaluate their antibacterial activity. The influence of lipophilic stearylamine on the characteristics of solid lipid nanoparticles was investigated. Solid lipid nanoparticles were characterized for size, zeta potential, encapsulation efficiency, differential scanning calorimetry and X-ray diffraction. The in vitro inhibitory activity of retinoic acid-lauric acid-loaded solid lipid nanoparticles was evaluated against Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. High encapsulation efficiency was obtained at initial time (94 ± 7% and 100 ± 4% for retinoic acid and lauric acid, respectively) and it was demonstrated that lauric acid-loaded-solid lipid nanoparticles provided the incorporation of retinoic acid. However, the presence of stearylamine is necessary to ensure stability of encapsulation. Moreover, retinoic acid-lauric acid-loaded solid lipid nanoparticles showed growth inhibitory activity against Staphylococcus epidermidis, Propionibacterium acnes and Staphylococcus aureus, representing an interesting alternative for the topical therapy of acne vulgaris.

  1. Introduction: Building Word Image, a New Arena for Architectural History

    Anne Hultzsch

    2016-09-01

    Full Text Available The study of word-image relationships is one of the most innovative and cross-disciplinary fields to have emerged in the humanities over the last decades. This special collection of 'Architectural Histories' opens up this area to architectural history by exploring the rising coexistence of the graphic and the verbal in the public dissemination of architecture in the 19th and early 20th centuries. Originating from a conference session at the Third International Meeting of the European Architectural History Network in Turin, June 2014, this selection of articles also presents the foundation for an EAHN Interest Group on Word & Image, which will help to define this new arena. Even if word-image relationships are, so far, rarely identified as a specific topic within our discipline, as architectural historians we already investigate them across periods, territories and subjects. The purpose of this collection is to make this a subject per se by examining descriptions and illustrations of buildings in printed and publicly disseminated media such as newspapers, journals, pamphlets, books, manuscripts or catalogues. We hope that the papers in this special collection of 'Architectural Histories' will encourage architectural historians of all fields to question the interplay between buildings, words and images afresh, thus building a new understanding of the verbal and visual presence of architecture.

    2016-06-01

    Full Text Available 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

    The physicochemical properties of organic (multi)component films for optoelectronic applications depend on both the mesoscopic and nanoscale architectures within the semiconducting material. Two main classes of semiconducting materials are commonly used: polymers and (liquid) crystals of small aromatic molecules. Whereas polymers (e.g., polyphenylenevinylenes and polythiophenes) are easy to process in solution in thin and uniform layers, small molecules can form highly defined (liquid) crystals featuring high charge mobilities. Herein, we combine the two material types by employing structurally well-defined polyisocyanopeptide polymers as scaffolds to precisely arrange thousands of electron-accepting molecules, namely, perylenebis(dicarboximides) (PDIs), in defined chromophoric wires with lengths of hundreds of nanometers. The polymer backbone enforces high control over the spatial location of PDI dyes, favoring both enhanced exciton and charge transfer. When blended with an electron-donor system such as regioregular poly(3-hexylthiophene), this polymeric PDI shows a relative improvement in charge generation and diffusion with respect to monomeric, aggregated PDI. In order to correlate this enhanced behavior with respect to the architecture, atomic force microscopy investigations on the mixtures were carried out. These studies revealed that the two polymers form interpenetrated bundles having a nanophase-segregated character and featuring a high density of contact points between the two different phases. In order to visualize the relationship between the architecture and the photovoltaic efficiency, Kelvin probe force microscopy measurements were carried out on submonolayer-thick films. This technique allowed for the first time the direct visualization of the photovoltaic activity occurring in such a nanoscale phase-segregated ultrathin film with true nanoscale spatial resolution, thus making possible a study of the correlation between function and architecture

    Full Text Available In the development of mobile robotic systems, a robotic architecture plays a crucial role in interconnecting all the sub-systems and controlling the system. The design of robotic architectures for mobile autonomous robots is a challenging and complex task. With a number of existing architectures and tools to choose from, a review of the existing robotic architecture is essential. This paper surveys the different paradigms in robotic architectures. A classification of the existing robotic architectures and comparison of different proposals attributes and properties have been carried out. The paper also provides a view on the current state of designing robot architectures. It also proposes a conceptual model of a generalised robotic architecture for mobile autonomous robots.Defence Science Journal, 2010, 60(1, pp.15-22, DOI:http://dx.doi.org/10.14429/dsj.60.96

  10. Topical ketoprofen patch.

    Mazières, Bernard

    2005-01-01

    Although oral nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in the treatment of a variety of acute and chronic pain conditions, their use may be associated with serious systemic adverse effects, particularly gastrointestinal disorders. In order to minimise the incidence of systemic events related to such agents, topical NSAIDs have been developed. Topical NSAIDs, applied as gels, creams or sprays, penetrate the skin, subcutaneous fatty tissue and muscle in amounts that are sufficient to exert a therapeutic effect on peripheral and central mechanisms in the absence of high plasma concentrations. Data indicate that topical NSAIDs are effective at relieving pain in a number of acute and chronic pain indications. This review article discusses the pharmacokinetics, efficacy and tolerability of a new formulation of ketoprofen available as a topical patch. The topical patch containing ketoprofen 100mg as the active principle has been developed using a novel delivery system that dispenses therapeutic doses of the drug directly to the site of injury. Pharmacokinetic data indicate that although plasma levels of ketoprofen are higher when the drug is administered as a patch versus a gel, the total systemic bioavailability of ketoprofen 100 mg administered via a patch is no more than 10% of that reported for ketoprofen 100 mg administered orally. Because the patch facilitates ketoprofen delivery over a 24-hour period, the drug remains continually present in the tissue subjacent to the site of application. High tissue but low plasma ketoprofen concentrations mean that while tissue concentrations are high enough to exert a therapeutic effect, plasma concentrations remain low enough to not result in systemic adverse events caused by elevated serum NSAID levels. Phase III clinical trials in patients with non-articular rheumatism and traumatic painful soft tissue injuries showed that the topical ketoprofen patch was significantly more effective than placebo at

    Full Text Available Background: A comparative study of topical feracrylum citrate versus adrenaline to minimise haemorrhage-related complications in paediatric hypospadiac patients. Patients and Methods: A total of 108 consecutive paediatric hypospadiac patients (48 in the study group and 60 control - random allocation were studied. In the study group, 1% feracrylum citrate solution was used and adrenaline (1:100,000 in controls. Results: Among the study group, average number of blood-soaked gauge pieces were 2.95/patient, correlating with average intraoperative blood loss of 14.74 ml. In controls, average blood-soaked gauge pieces were 4.83/patient corresponding to an average blood loss of 24.13 ml. The average amount of blood loss during surgery in the <5 years was 13.70 ml/patient in the feracrylum group, while the same in the adrenaline group was 23.45 ml. Average duration of surgery was 79 min in the study group, while the same in controls was 94 min/patient. Average number of cauterisations was 0.255/patient in the study group and 0.583/patient among controls. Postoperative haematoma was seen in 8% study group compared with 18% controls. Wound oedema appeared in 4.17% study group and 11.67% controls. Postoperative complications were higher among controls. Conclusions: Feracrylum is more efficient and safer topical haemostatic agent than adrenaline. It reduced the frequency of cauterisation and tissue damage, intraoperative blood loss, and postoperative complications.

    2010-01-01

    To harmonize the individual architectures of the different commands, services, and agencies dealing with the development and procurement of Command, Control, Communications, Computing, Surveillance, Reconnaissance, and Intelligence (C4ISR) systems, the C4ISR Architecture Framework was developed based on existing and matured modeling techniques and methods. Within a short period, NATO adapted this method family as the NATO Consultation, Command, and Control (C3) System Architecture Framework to harmonize the efforts of the different nations. Based on these products, for every system to be fielded to be used in the US Armed Forces, a C4I Support Plan (C4ISP) has to be developed enabling the integration of the special system into the integrated C4I Architecture. The tool set proposed by these architecture frameworks connects operational views of the military user, system views of the developers, and the technical views for standards and integration methods needed to make the network centric system of systems wor...

However, up to the present day, the topic of the “unbuilt” has been analyzed just episodically in literature and sources. The article touches upon the historical development of unrealized architectural works, as well as their artistic value and role within various historical periods of Lithuanian architecture. One of the chapters briefly reviews the relevance and development of unrealized projects during the period since Czarist Russian occupation (1795 to the restoration of Lithuanian independence (1990. Furthermore, the deeper analysis of the Soviet period (1940–1990 “dead” architecture is presented. While exploring “the unrealized”, attention has been also paid to what was actu ally built, therefore the prevailing architectural styles, tendencies and examples of the corresponding decade (in Lithuania and worldwide have been studied.Article in Lithuanian

    Full Text Available By aggregating self-reported health statuses across millions of users, we seek to characterize the variety of health information discussed in Twitter. We describe a topic modeling framework for discovering health topics in Twitter, a social media website. This is an exploratory approach with the goal of understanding what health topics are commonly discussed in social media. This paper describes in detail a statistical topic model created for this purpose, the Ailment Topic Aspect Model (ATAM, as well as our system for filtering general Twitter data based on health keywords and supervised classification. We show how ATAM and other topic models can automatically infer health topics in 144 million Twitter messages from 2011 to 2013. ATAM discovered 13 coherent clusters of Twitter messages, some of which correlate with seasonal influenza (r = 0.689 and allergies (r = 0.810 temporal surveillance data, as well as exercise (r =  .534 and obesity (r =  -.631 related geographic survey data in the United States. These results demonstrate that it is possible to automatically discover topics that attain statistically significant correlations with ground truth data, despite using minimal human supervision and no historical data to train the model, in contrast to prior work. Additionally, these results demonstrate that a single general-purpose model can identify many different health topics in social media.

    2016-09-01

    Full Text Available Decisions about design are invariably decisions about materials (Temple, 2011,p 50.Design education seeks to mimic the design process in landscape architectural practice. Yet the educational process is fundamentally different because design ideas are rarely tested through building. Student learning, therefore, remains in the realm of abstraction: the representation of a design idea without translation into the actual material these ideas are intended to shape. Thinking through ideas at full scale off ers an alternative way to explore design learning so students understand the spatial, social and material consequences of their ideas. Working at the 1:1 scale gives them an insight into the implications of their design decisions and experience in working directly with the materials of their concern. It also off ers an opportunity to work one to one with each other and clients.

  11. 2 PROBLEM OF PRESERVATION OF ARCHITECTURAL MONUMENTS OF OLD MOSCOW AS VIEWED BY ITS RESIDENTS

    Full Text Available The authors consider one of the most relevant issues of the present-day urban planning, the issue of preservation of the historic environment, the architectural and urban planning space of the megalopolis in the context of the accelerated pace of urbanization, expansion of the capital in the course of its implementation. The authors argue that the problem considered in the paper is not easy to tackle. The point is that the need to preserve historic built-up areas is hardly reconcilable with the need to upgrade the urban infrastructure. A social conflict is inevitable in this context. The authors track development of this social conflict from the sixties of the 20ieth century and through the present time and provide their resolutions to this contradiction.

  12. An Idiotypic Immune Network as a Short Term Learning Architecture for Mobile Robots

    CERN Document Server

    Whitbrook, Amanda; Garibaldi, Jonathan M

    2009-01-01

    A combined Short-Term Learning (STL) and Long-Term Learning (LTL) approach to solving mobile robot navigation problems is presented and tested in both real and simulated environments. The LTL consists of rapid simulations that use a Genetic Algorithm to derive diverse sets of behaviours. These sets are then transferred to an idiotypic Artificial Immune System (AIS), which forms the STL phase, and the system is said to be seeded. The combined LTL-STL approach is compared with using STL only, and with using a handdesigned controller. In addition, the STL phase is tested when the idiotypic mechanism is turned off. The results provide substantial evidence that the best option is the seeded idiotypic system, i.e. the architecture that merges LTL with an idiotypic AIS for the STL. They also show that structurally different environments can be used for the two phases without compromising transferability

    2013-06-01

    Central tarsal bone (CTB) fractures are well documented and are a subject of increasing importance in human, equine and canine athletes although the mechanism of these fractures in dogs is not fully understood and an extrapolation from human medicine may not be accurate. This study reports the use of high-resolution computed tomography (CT) of 91 tarsal joints from 47 dogs to generate a more detailed in situ anatomical description of the CTB architecture in order to obtain a better understanding of the pathogenesis of CTB fractures in this species. The dogs studied represented a wide range of ages, breeds and levels of habitual physical activity and the angles of the tarsal joints studied ranged between maximal flexion (16.4°) and maximal extension (159.1°). Regardless of tarsal angle, the CTB articulated with the calcaneus exclusively at the level of its plantar process (PPCTB) in all dogs. The PPCTB presented two distinct parts in all dogs, a head and a neck. The calcaneus tended to rely on the PPCTB neck during flexion and on the PPCTB head during extension. This study describes new tarsal elements for the first time, including the calcaneal articular process, the fourth tarsal bone plantar articular process and the talar plantar prominence of the CTB. Based on calcaneo-PPCTB architecture, it is postulated that the PPCTB is a keystone structure and that at least some of CTB fractures in dogs could either commence at or are induced at this level due to the impingement forces exercised by the calcaneus.

  15. Gay-Straight Alliances as settings to discuss health topics: individual and group factors associated with substance use, mental health, and sexual health discussions.

    2017-06-01

    Sexual minority (e.g. lesbian, gay, bisexual, questioning; LGBQ) and gender minority (e.g. transgender) youth experience myriad health risks. Gay-Straight Alliances (GSAs) are school-based settings where they may have opportunities to discuss substance use, mental health, and sexual health issues in ways that are safe and tailored to their experiences. Attention to these topics in GSAs could aid in developing programming for these settings. Among 295 youth from 33 Massachusetts high-school GSAs (69% LGBQ, 68% cisgender female, 68% White, Mage = 16.06), we examined how often youth discussed these topics within their GSA and identified factors associated with having more of these discussions. Youth and GSAs as a whole varied in their frequency of discussing these topics. Youth who accessed more information/resources in the GSA and did more advocacy more frequently engaged in discussions around substance use, mental health and sexual health. Youth who reported greater victimization more often discussed substance use and mental health, but not sexual health. Finally, GSAs whose members collectively reported greater victimization more frequently discussed these topics. These findings can assist the development of health programming to be delivered within GSAs. © The Author 2017. Published by Oxford University Press. All rights reserved.

  16. 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.

  20. EVALUATION OF UTILIZING SERVICE ORIENTED ARCHITECTURE AS A SUITABLE SOLUTION TO ALIGN UNIVERSITY MANAGEMENT INFORMATION SYSTEMS AND LEARNING MANAGEMENT SYSTEMS

    Directory of Open Access Journals (Sweden)

    A. M. RIAD

    2009-10-01

    Full Text Available To help universities achieve their goals, it is important to align managerial functionalities side by side with educational aspects. Universities consume University Management Information Systems (UMIS to handle managerial aspects as they do with Learning Management Systems (LMS to achieve learning objectives. UMIS advances LMS by decades and has reached stable and mature consistency level. LMS is the newly acquired solution in Universities; compared to UMIS, and so adopting LMSs in universities can be achieved via three different deployment approaches. First approach believes in LMS ability to replace UMIS and performing its functionalities. Second approach presents the idea of extending UMIS to include LMS functionalities. Third approach arises from the shortages of the two proposed approaches and present integration between both as the appropriate deployment approach. Service Oriented Architecture (SOA is a design pattern that can be used as a suitable architectural solution to align UMIS and LMS. SOA can be utilized in universities to overcome some of information systems’ challenges like the integration between UMIS and LMS. This paper presents the current situation at Mansoura University; Egypt, presents integration as the most suitable solution, and evaluates three different implementation techniques: Dynamic Query, Stored Procedure, and Web services. Evaluation concludes that though SOA enhanced many different aspects of both UMIS and LMS; and consequently university overall. It is not recommended to adopt SOA via Web services as the building unit of the system, but as the interdisciplinary interface between systems.

  1. A Phobos-Deimos Mission as an Element of the NASA Mars Design Reference Architecture 5.0

    Science.gov (United States)

    Hoffman, Stephen J.

    2011-01-01

    NASA has conducted a series of mission studies over the past 25 years examining the eventual exploration of the surface of Mars by humans. The latest version of this evolutionary series of design reference missions/architectures - Design Reference Architecture 5 or DRA-5 - was completed in 2007. This paper examines the implications of including a human mission to explore the moons of Mars and teleoperate robots in various locations, but not to land the human crews on Mars, as an element of this reference architecture. Such a mission has been proposed several times during this same 25 year evolution leading up to the completion of DRA-5 primarily as a mission of testing the in-space vehicles and operations while surface vehicles and landers are under development. But such a precursor or test mission has never been explicitly included as an element of this Architecture. This paper will first summarize the key features of the DRA-5 to provide context for the remainder of the assessment. This will include a description of the in-space vehicles that would be the subject of a shakedown test during the Mars orbital mission. A decision tree will be used to illustrate the factors that will be analyzed, and the sequence in which they will be addressed, for this assessment. The factors that will be analyzed include the type of interplanetary transfer orbit (opposition class versus conjunction class), the type of parking orbit (circular versus elliptical), and the type of propulsion technology (high thrust chemical versus nuclear thermal rocket). The manner in which each of these factors impacts an individual mission will be described. In addition to the direct impact of these factors, additional considerations impacting crew health and overall programmatic outcomes will be discussed. Numerical results for each of the factors in the decision tree will be grouped with derived qualitative impacts from crew health and programmatic consideration. These quantitative and qualitative

    2016-05-01

    Full Text Available Environmental and sustainability assessment tools have an important role in moving towards a better world, bringing knowledge and raising awareness. In the architecture and civil engineering sector, these assessment tools help in moving forward to constructions that have less economic, environmental and social impacts. At present, there are numerous assessment tools and methods with different approaches and scopes that have been analyzed in numerous technical reviews. However, there is no agreement about which method should be used for each evaluation case. This research paper synthetically analyzes the main sustainability assessment methods for the construction sector, comparing their strengths and weaknesses in order to present the challenges of the Spanish Integrated Value Model for Sustainability Assessment (MIVES. MIVES is a Multi-Criteria Decision Making method based on the value function concept and the Seminars of experts. Then, this article analyzes MIVES advantages and weak points by going through its methodology and two representative applications. At the end, the area of application of MIVES is described in detail along with the general application cases of the main types of assessment tools and methods.

  4. 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...

    Full Text Available Antimicrobial activity of Usnea barbata especially against bacteria involved in pathogenesis of various skin conditions has been well documented in literature. Nevertheless, there are no papers dealing with formulation of its isolates into topical preparations for treatment of skin infections. In present study, alkyl polyglucoside (APG - based vehicle was developed as carrier of U. barbata CO2-supercritical extract (U-SE that demonstrated the best antimicrobial potential in preliminary screening. For comparison, chosen extract in the same concentration and using the same procedure was incorporated into a pharmacopoeial vehicle. Comparative evaluation of physicochemical stability, efficiency and safety proved APG-based vehicle to possess certain preferential features as carrier of U-SE compared to the reference one, composing a topical formulation with potential clinical relevance in treatment of skin infections.

    Achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermal and transdermal products. The use of penetration enhancers could provide a successful mean for this purpose. The aim of this study was to develop Clotrimazole gel and to evaluate the effect of almond oil and tween 80 (in different concentrations), on the permeation of drug through rabbit skin in vitro. In order to investigate the effect of penetration enhancers used in this study on the permeation of Clotrimazole through sections of excised rabbit skin, Franz diffusion cell was employed. Sample solution was withdrawn at specific time interval up to 24 h. Significant difference in permeation among the eight formulations was seen in the study. The permeation profile of various formulations also showed that the added enhancers in individual batches affected the permeation of the drug. Drug permeation increased with increased concentration of Tween 80 and decreased concentration of almond oil. Furthermore, almond oil combined with tween 80 showed synergistic effect. The clotrimazole gels were successfully formulated and could be beneficial for topical use.

    N-substituted-(indol-3-yl)carboxamides 10-15 and alkanamides 16-18 were prepared starting from the corresponding acids and submitted to screening for evaluation of their anti-inflammatory activity. None of the considered carboxamides exhibited significant inhibitory effect in the carrageenin-induced rat paw oedema after oral administration of 0.1 mM x kg(-1); nevertheless introduction of an alkyl chain, leading to alkanamides 16-18, induced moderate to high activity: 46-95% inhibition. The efficacy of these compounds in the inhibition of topical inflammation was confirmed by measuring reduction of ear thickness in the acute tetradecanoyl phorbol acetate (TPA)-induced mouse ear swelling assay. Preliminary pharmacomodulation brought to the fore that toxic effects induced, at 0.4 mM x kg(-1), by N-(pyridin-4-yl)(indol-3-yl)propanamide (17) could be attenuated or suppressed by 5-fluorination or introduction of a methoxycarbonylborane moiety, leading to 18 and 21.

    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.

  15. Recent advances in topical anesthesia

    Science.gov (United States)

    2016-01-01

    Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain. PMID:28879311

    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

    The vertebrate nuclear pore complex (NPC) is a macromolecular assembly of protein subcomplexes forming a structure of eightfold radial symmetry. The NPC core consists of globular subunits sandwiched between two coaxial ring-like structures of which the ring facing the nuclear interior is capped by a fibrous structure called the nuclear basket. By postembedding immunoelectron microscopy, we have mapped the positions of several human NPC proteins relative to the NPC core and its associated basket, including Nup93, Nup96, Nup98, Nup107, Nup153, Nup205, and the coiled coil-dominated 267-kDa protein Tpr. To further assess their contributions to NPC and basket architecture, the genes encoding Nup93, Nup96, Nup107, and Nup205 were posttranscriptionally silenced by RNA interference (RNAi) in HeLa cells, complementing recent RNAi experiments on Nup153 and Tpr. We show that Nup96 and Nup107 are core elements of the NPC proper that are essential for NPC assembly and docking of Nup153 and Tpr to the NPC. Nup93 and Nup205 are other NPC core elements that are important for long-term maintenance of NPCs but initially dispensable for the anchoring of Nup153 and Tpr. Immunogold-labeling for Nup98 also results in preferential labeling of NPC core regions, whereas Nup153 is shown to bind via its amino-terminal domain to the nuclear coaxial ring linking the NPC core structures and Tpr. The position of Tpr in turn is shown to coincide with that of the nuclear basket, with different Tpr protein domains corresponding to distinct basket segments. We propose a model in which Tpr constitutes the central architectural element that forms the scaffold of the nuclear basket.

    This study was done to assess whether classes containing topics derived from two college courses, Abnormal Psychology and Health Psychology, could be used in a class room format to reduce alcohol and other drug abuse among at-risk college students. Topics covered included stress and stress management, alcohol and other drug use and abuse, chronic illnesses and psychological disorders that develop from an unhealthy lifestyle, and factors that play a role in good health and well-being. Students were enrolled in a semester-long course for college credit as an alternative to punitive sanctions for on-campus alcohol violations and other drug violations. The Midwest Institute on Drug Use Survey and the CORE Alcohol and Drug Survey were administered on the first and last days of class. Analysis indicated a significant self-reported reduction in drug use and associated negative symptoms and behavioral effects. Women were more likely to report reductions in drug use than men.

    Full Text Available Education is a contiguous and consecutive process. Thereby learning skills and knowledge in any context, requires strong and powerful academic basis. To reach this target, evaluation as a means to recognize student’s learning level and making decisions for further educating steps seems essential. All the Educational systems have sort of official examination, assessment or grading policy to measure student’s learning stage. In the typical policy, students are told clearly about the proposed assessment program and the relative weightings of the various components and they are given timely and helpful feedback after each assessment stage. Internationally, in these decades, universities and educators have become increasingly committed to making assessment and grading more effective in promoting student learning. Appraisal methods and grading systems in studio based educating systems, such as architecture, more than other majors and fields needs attention and scrutiny. Because transmitting the success amount of solving ill-defined problems in design studios to grading symbols are more difficult than multiple choice tests and even open ended questions. The primary interest of this study is in grading methods that claim to be criteria-based. This study tries to hybrid the criteria based models to introduce a new appraisal method in evaluating architectural projects in universities, based on a review of the most common grading policies.

  3. Evaluation of RU58841 as an anti-androgen in prostate PC3 cells and a topical anti-alopecia agent in the bald scalp of stumptailed macaques.

    The effect of androgen receptor transcriptional activation by RU58841, a nonsteroidal anti-androgen, was studied in the human prostate cancer PC3 cell line by cotransfection with wild-type androgen receptor (wt AR) and an androgen-responsive reporter (MMTV-ARE-CAT) construct. Anti-and rogens, hydroxyflutamide, and Casodex, and the antiestrogen, genistein, were studied in parallel for comparison with RU58841. The wt AR was activated only by the androgen dihydrotestosterone (DHT). Neither the anti-androgens nor antiestrogen can enhance AR transcriptional activity at 10(-11)-10(-7)M in PC3 cells. Hydroxyflutamide, RU58841, and Casodex, but not genistein, displayed competitively suppressive effects on DHT activation of wt AR. The potency of RU58841 was comparable to that of hydroxyflutamide. From this result, topical application of RU58841, which is considered to be a potential therapy for skin diseases, may induce systemic side effects. However, RU58841, on topical application, revealed a potent increase in density, thickening, and length of hair in the macaque model of androgenetic alopecia, whereas no systemic effects were detected. Together our results suggest that RU58841 may have potent antagonism to the wt AR and could be considered as a topically applied active anti-androgen for the treatment of androgen-dependent skin disorders, such as acne, androgenetic alopecia, and hirsutism.

    Metallofoldamers are oligomers that fold into three-dimensional structures in a controlled manner upon coordination with metal ions. Molecules in this class have shown an impressive ability to form single-handed helical structures and other three-dimensional architectures. Several metallofoldamers have been applied as sensors due to their selective folding when binding to a specific metal ion, while others show promise for applications as responsive materials on the basis of their ability to fold and unfold upon changes in the oxidation state of the coordinated metal ion, and as novel catalysts. Metallofoldamers: From Helicates to Biomimetic Architectures describes the variety of interactions between oligomers and metal species, with a focus on non-natural synthetic molecules. Topics covered include: the major classes of foldamers and their folding driving force metalloproteins and metalloenzymes helicates: self-assembly, structure and applications abiotic metallo-DNA metallo-PNA and iDNA metallopeptides inte...

  5. 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.

    Hirche, Z; Xiong, L; Hirche, C; Willis, S

    2016-04-01

    Topical negative pressure therapy (TNPT) has been established for surgical wound therapy with different indications. Nevertheless, there is only sparse evidence regarding its therapeutic superiority or cost-effectiveness in the German DRG system (G-DRG). This study was designed to analyse the cost-effectiveness of TNPT in the G-DRG system with a focus on daily treatment costs and reimbursement in a general surgery care setting. In this retrospective study, we included 176 patients, who underwent TNPT between 2007 and 2011 for general surgery indications. Analysis of the cost-effectiveness involved 149 patients who underwent a simulation to calculate the reimbursement with or without TNPT by a virtual control group in which the TNP procedure was withdrawn for DRG calculation. This was followed by a calculation of costs for wound dressings and TNPT rent and material costs. Comparison between the "true" and the virtual group enabled calculation of the effective remaining surplus per case. Total reimbursement by included TNPT cases was 2,323 ,70.04 €. Costs for wound dressings and TNPT rent were 102,669.20 €. In 41 cases there was a cost-effectiveness (27.5%) with 607,422.03 € with TNP treatment, while the control group without TNP generated revenues of 442,015.10 €. Costs for wound dressings and TNPT rent were 47,376.68 €. In the final account we could generate a cost-effectiveness of 6759 € in 5 years per 149 patients by TNPT. In 108 cases there was no cost-effectiveness (72.5%). TNPT applied in a representative general surgery setting allows for wound therapy without a major financial burden. Based on the costs for wound dressings and TNPT rent, a primarily medically based decision when to use TNPT can be performed in a balanced product cost accounting. This study does not analyse the superiority of TNPT in wound care, so further prospective studies are required which focus on therapeutic superiority and cost-effectiveness. Georg Thieme

    There are few more dramatic illustrations of the vicissitudes of laboratory architecturethan the contrast between Building 20 at the Massachusetts Institute of Technology (MIT) and its replacement, the Ray and Maria Stata Center. Building 20 was built hurriedly in 1943 as temporary housing for MIT's famous Rad Lab, the site of wartime radar research, and it remained a productive laboratory space for over half a century. A decade ago it was demolished to make way for the Stata Center, an architecturally striking building designed by Frank Gehry to house MIT's computer science and artificial intelligence labs (above). But in 2004 - just two years after the Stata Center officially opened - the building was criticized for being unsuitable for research and became the subject of still ongoing lawsuits alleging design and construction failures.

  15. Digitally-Driven Architecture

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available The shift from mechanical to digital forces architects to reposition themselves: Architects generate digital information, which can be used not only in designing and fabricating building components but also in embedding behaviours into buildings. This implies that, similar to the way that industrial design and fabrication with its concepts of standardisation and serial production influenced modernist architecture, digital design and fabrication influences contemporary architecture. While standardisation focused on processes of rationalisation of form, mass-customisation as a new paradigm that replaces mass-production, addresses non-standard, complex, and flexible designs. Furthermore, knowledge about the designed object can be encoded in digital data pertaining not just to the geometry of a design but also to its physical or other behaviours within an environment. Digitally-driven architecture implies, therefore, not only digitally-designed and fabricated architecture, it also implies architecture – built form – that can be controlled, actuated, and animated by digital means.In this context, this sixth Footprint issue examines the influence of digital means as pragmatic and conceptual instruments for actuating architecture. The focus is not so much on computer-based systems for the development of architectural designs, but on architecture incorporating digital control, sens­ing, actuating, or other mechanisms that enable buildings to inter­act with their users and surroundings in real time in the real world through physical or sensory change and variation.

    2012-09-01

    Full Text Available How to use for the architectural design, the simulation coming from a large size data model? The topic is related to the phase coming usually after the acquisition of the data, during the construction of the model and especially after, when designers must have an interaction with the simulation, in order to develop and verify their idea. In the case of study, the concept of interaction includes the concept of real time "flows". The work develops contents and results that can be part of the large debate about the current connection between "architecture" and "movement". The focus of the work, is to realize a collaborative and participative virtual environment on which different specialist actors, client and final users can share knowledge, targets and constraints to better gain the aimed result. The goal is to have used a dynamic micro simulation digital resource that allows all the actors to explore the model in powerful and realistic way and to have a new type of interaction in a complex architectural scenario. On the one hand, the work represents a base of knowledge that can be implemented more and more; on the other hand the work represents a dealt to understand the large constructed architecture simulation as a way of life, a way of being in time and space. The architectural design before, and the architectural fact after, both happen in a sort of "Spatial Analysis System". The way is open to offer to this "system", knowledge and theories, that can support architectural design work for every application and scale. We think that the presented work represents a dealt to understand the large constructed architecture simulation as a way of life, a way of being in time and space. Architecture like a spatial configuration, that can be reconfigurable too through designing.

    Mosby, Brian M; Goloby, Mark; Díaz, Agustín; Bakhmutov, Vladimir; Clearfield, Abraham

    2014-03-11

    Surface-functionalized zirconium phosphate (ZrP) nanoparticles were synthesized using a combination of ion exchange and self-assembly techniques. The surface of ZrP was used as a platform to deposit tetravalent metal ions by direct ion exchange with the protons of the surface phosphate groups. Subsequently, phosphonic acids were attached to the metal ion layer, effectively functionalizing the ZrP nanoparticles. Use of axially oriented bisphosphonic acids led to the ability to build layer-by-layer assemblies from the nanoparticle surface. Varying the metal ion and ligand used allowed designable architectures to be synthesized on the nanoparticle surface. X-ray powder diffraction, XPS, electron microprobe, solid-state NMR, FTIR, and TGA were used to characterize the synthesized materials.

    2011-03-08

    This invention relates to a method for producing components with internal architectures, and more particularly, this invention relates to a method for producing structures with microchannels via the use of diffusion bonding of stacked laminates. Specifically, the method involves weakly bonding a stack of laminates forming internal voids and channels with a first generally low uniaxial pressure and first temperature such that bonding at least between the asperites of opposing laminates occurs and pores are isolated in interfacial contact areas, followed by a second generally higher isostatic pressure and second temperature for final bonding. The method thereby allows fabrication of micro-channel devices such as heat exchangers, recuperators, heat-pumps, chemical separators, chemical reactors, fuel processing units, and combustors without limitation on the fin aspect ratio.

  14. 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

    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.

  17. Travels in Architectural History

    Directory of Open Access Journals (Sweden)

    Davide Deriu

    2016-11-01

    Full Text Available Travel is a powerful force in shaping the perception of the modern world and plays an ever-growing role within architectural and urban cultures. Inextricably linked to political and ideological issues, travel redefines places and landscapes through new transport infrastructures and buildings. Architecture, in turn, is reconstructed through visual and textual narratives produced by scores of modern travellers — including writers and artists along with architects themselves. In the age of the camera, travel is bound up with new kinds of imaginaries; private records and recollections often mingle with official, stereotyped views, as the value of architectural heritage increasingly rests on the mechanical reproduction of its images. Whilst students often learn about architectural history through image collections, the place of the journey in the formation of the architect itself shifts. No longer a lone and passionate antiquarian or an itinerant designer, the modern architect eagerly hops on buses, trains, and planes in pursuit of personal as well as professional interests. Increasingly built on a presumption of mobility, architectural culture integrates travel into cultural debates and design experiments. By addressing such issues from a variety of perspectives, this collection, a special 'Architectural Histories' issue on travel, prompts us to rethink the mobile conditions in which architecture has historically been produced and received.

    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

    Full Text Available Topics identification (TI is the process that consists in determining the main themes present in natural language documents. The current TI modeling paradigm aims at acquiring semantic information from statistic properties of large text datasets. We investigate the mental mechanisms responsible for the identification of topics in a single document given existing knowledge. Our main hypothesis is that topics are the result of accumulated neural activation of loosely organized information stored in long-term memory (LTM. We experimentally tested our hypothesis with a computational model that simulates LTM activation. The model assumes activation decay as an unavoidable phenomenon originating from the bioelectric nature of neural systems. Since decay should negatively affect the quality of topics, the model predicts the presence of short-term memory (STM to keep the focus of attention on a few words, with the expected outcome of restoring quality to a baseline level. Our experiments measured topics quality of over 300 documents with various decay rates and STM capacity. Our results showed that accumulated activation of loosely organized information was an effective mental computational commodity to identify topics. It was furthermore confirmed that rapid decay is detrimental to topics quality but that limited capacity STM restores quality to a baseline level, even exceeding it slightly.

    2016-01-01

    Full Text Available Introduction: One of the most common side effects of bisphosphonate intake is osteonecrosis of the jaw (ONJ which may develop following dentoalveolar interventions. Despite the vast available protocols, there is no clear guideline in the management of this condition. In osteonecrosis, the number and proliferation of bone-forming cells as well as vascularity are disturbed. Erythropoietin (EPO is a hematopoietic hormone with angiogenic, osteogenic, and antiapoptotic properties. The Hypothesis: It is suggested to utilize poly lactic-co-glycolic acid hydrogel containing 1500-3000 IU/kg EPO following dentoalveolar surgery in samples receiving bisphosphonates as a preventive or therapeutic agent. Evaluation of the Hypothesis: Considering the pathophysiology of ONJ and therapeutic properties of EPO, it is assumed that EPO may be effective in treatment of ONJ. Furthermore, as a preventive measure, utilizing EPO following dentoalveolar surgery may be beneficial in the patients at risk of ONJ.

    Oral lichen planus is an autoimmune disorder with several challenges in treatment. Photodynamic therapy has been proposed as a new treatment option for the disease. The present study compared the clinical effects of the photodynamic therapy and dexamethasone mouthwash in the treatment of oral lichen planus lesions. In this randomized clinical trial, 30 patients with oral lichen planus were included.15 patients were treated with 5% methylene blue mediated photodynamic therapy using Fotosan device for 30seconds (630nm wavelength and 7.2-14.4J/CM2 dose) for 4 sessions in the days 1,4,7,14. In another group, the treatment was done on 15 patients by 0.5mg tab dexamethasone solution in 5cc water, rinsed 4 times in a day within two weeks. The sign score, symptoms scores (pain), clinical severity and treatment efficacy were measured at the days 15,30,60,90 after beginning of the treatment. The results were subjected to Mann-whitney U test in both groups. No significant difference existed between two modalities regarding the treatment efficacy index, sign score, symptom score and clinical severity on the 15, 30, 60 and 90 post-treatment days. Decreases in patient's symptoms were statistically significant in both groups. Photodynamic therapy was as effective as the dexamethasone mouth wash in the treatment of oral lichen planus It could be used as a safe modality in the treatment of oral lichen planus lesions without identified side effects.

    2013-12-01

    Full Text Available This paper examines deconstruction in architecture and forms used, which triggered by dispute of form and its scientification claimed by deconstructivists. Deconstruction terminologyis studied in the first part related to architecture field as a base knowledge. Some sample works of known deconstructionist architects are assessed in order to understand how their building is deconstructed and what forms they used. Discussion about form and its relation to other fields is then pursued by discussing the involvement of terminology of science, aesthetic pattern, and human life. The results of this discussion give clear understanding how form related to deconstruction in architecture are used.

  14. Fractal Geometry of Architecture

    Science.gov (United States)

    Lorenz, Wolfgang E.

    In Fractals smaller parts and the whole are linked together. Fractals are self-similar, as those parts are, at least approximately, scaled-down copies of the rough whole. In architecture, such a concept has also been known for a long time. Not only architects of the twentieth century called for an overall idea that is mirrored in every single detail, but also Gothic cathedrals and Indian temples offer self-similarity. This study mainly focuses upon the question whether this concept of self-similarity makes architecture with fractal properties more diverse and interesting than Euclidean Modern architecture. The first part gives an introduction and explains Fractal properties in various natural and architectural objects, presenting the underlying structure by computer programmed renderings. In this connection, differences between the fractal, architectural concept and true, mathematical Fractals are worked out to become aware of limits. This is the basis for dealing with the problem whether fractal-like architecture, particularly facades, can be measured so that different designs can be compared with each other under the aspect of fractal properties. Finally the usability of the Box-Counting Method, an easy-to-use measurement method of Fractal Dimension is analyzed with regard to architecture.

    The main purpose of this study was to analyze the contribution of using hypertext and pedagogic mediation in search of a Meaningful Learning Process in Sciences. We investigate the usage of hypertext in the teaching and learning methods of Astronomy modules. A survey was conducted with students from the 9th grade of Primary School of a public school in the city of Goiânia, Goiás in Brazil. We have analyzed the possibilities that hypermedia can offer in the teaching and learning process, using as reference David Ausubel's Theory of Meaningful Learning. The study was divided into four phases: application of an initial questionnaire on students, development of didactic material (hypertext), six classes held in a computer lab with the use of hypermedia and a final questionnaire applied in the lab after classes. This research indicated that the use of hypertext linked to pedagogical mediation processes is seen as a motivational tool and has potential to foster to Meaningful Learning.

  18. Human-competitive automatic topic indexing

    CERN Document Server

    Medelyan, Olena

    2009-01-01

    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...

  19. Nanoscale amphiphilic macromolecules as lipoprotein inhibitors: the role of charge and architecture

    Wang, Jinzhong; Plourde, Nicole M; Iverson, Nicole; Moghe, Prabhas V; Uhrich, Kathryn E

    2007-01-01

    A series of novel amphiphilic macromolecules composed of alkyl chains as the hydrophobic block and poly(ethylene glycol) as the hydrophilic block were designed to inhibit highly oxidized low density lipoprotein (hoxLDL) uptake by synthesizing macromolecules with negatively charged moieties (ie, carboxylic acids) located in the two different blocks. The macromolecules have molecular weights around 5,500 g/mol, form micelles in aqueous solution with an average size of 20–35 nm, and display critical micelle concentration values as low as 10−7 M. Their charge densities and hydrodynamic size in physiological buffer solutions correlated with the hydrophobic/hydrophilic block location and quantity of the carboxylate groups. Generally, carboxylate groups located in the hydrophobic block destabilize micelle formation more than carboxylate groups in the hydrophilic block. Although all amphiphilic macromolecules inhibited unregulated uptake of hoxLDL by macrophages, inhibition efficiency was influenced by the quantity and location of the negatively charged-carboxylate on the macromolecules. Notably, negative charge is not the sole factor in reducing hoxLDL uptake. The combination of smaller size, micellar stability and charge density is critical for inhibiting hoxLDL uptake by macrophages. PMID:18203436

    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 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.

    The objective of this study was to use pinhão derivatives, starch and coat extract, as new natural ingredients to develop cosmetic formulations. Two types of formulation, gel and emulgel, and their controls were developed. The formulations were characterized by stability studies using thermal stress. The parameters analyzed were resistance to centrifugation, pH, spreadability, rheology, content of phenolic compounds and antioxidant activity. Sensory analysis was also performed to verify the acceptability of the ingredients to potential consumers. The pH was kept the same after heating/freezing cycles for all formulations, and the formulations showed stability by resistance to centrifugation. The formulations did not induce any skin irritation or cutaneous pH alteration. The pinhão starch addition improved spreadability stability and increased viscosity when compared with control formulations. The pinhão coat extract used in these formulations is a good source of phenolic compounds and antioxidant activity. Moreover, sensory analysis indicates that the emulgel formulation is the best vehicle for adding pinhão starch and pinhão coat extract.

  4. Architectural geometry

    KAUST Repository

    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.

    Full Text Available Israel is a new nation with ancient roots. Over the past century the Zionist return to the land and the building of a modern nation has had a counterpart in language: the revitalisation of Hebrew as spoken tongue. There is a design analogy with the immigrant process, learning Hebrew, and ulpan (language classes for new immigrants.' Designers too, have learned the basics of the landscape language, appreciated its character and nuance, and found out how to be expressive within its vocabulary and structure. For Israeli landscape architects there has been a conscious search for a language of landscape design. As a result of this quest, a palette of identifiable materials, forms, compositions, and functions has emerged, and these have been used to create a design narrative which speaks of Israel's complex national culture and identity. This paper explores the continuing process through a case study of one landscape space, the wadi/nahal.

    The fractal globule is a compact polymer state that emerges during polymer condensation as a result of topological constraints which prevent one region of the chain from passing across another one. This long-lived intermediate state was introduced in 1988 (Grosberg et al. 1988) and has not been observed in experiments or simulations until recently (Lieberman-Aiden et al. 2009). Recent characterization of human chromatin using a novel chromosome conformational capture technique brought the fra...

  10. Universal Design as a Booster for Housing Quality and Architectural Practice.

    Science.gov (United States)

    Denizou, Karine

    2016-01-01

    Norwegian central government has for the last decade increasingly focused on universal design. Fundamental changes in the Norwegian building code and corresponding regulations in 2010 give an apparently clear framework for the implementation of accessibility and universal design. However, it seems that neither increased awareness of accessibility requirements and universal design, nor compliance with the building code guarantees improvement of housing quality and usability. The Norwegian regulations have gone further in the direction of performance requirements than most other countries. This applies to all types of requirements, including requirements for usability, functionality and accessibility. Hardly any specifications are to be found in the regulations. Ideally, this lack of specifications should give designers the opportunity to develop innovative answers and hence to respond to different contexts and needs. Still, many architects and builders ask for clear specifications, in order to simplify and speed up design processes and make control of solutions easier. Many architects understand guidelines as minimum requirements, and are thus reproducing the identical solutions without considering the context and the needs of the users. They see accessibility as another regulatory pressure and requirements as restrictions rather than positive incentives. However, there are examples of designers who have internalised the regulatory framework and thus are able to create and integrate inclusive design in their daily work. Based on recent research conducted by SINTEF Building and Infrastructure and financed by the Norwegian State Housing Bank, this paper presents examples of practice where dwellings have been developed within a framework of universal design. Focus of the research has been on the approach of the design team and their understanding and use of the regulatory framework in order to create better homes in dialogue with the building authorities.

  11. Art and architecture as experience: an alternative approach to bridging art history and the neurosciences.

    Science.gov (United States)

    Zschocke, Nina

    2012-08-01

    In 1972, Michael Baxandal characterizes the processes responsible for the cultural relativism of art experience as highly complex and unknown in their physiological detail. While art history still shows considerable interest in the brain sciences forty years later, most cross-disciplinary studies today are referring to the neurosciences in an attempt to seek scientific legitimization of variations of a generalized and largely deterministic model of perception, reducing interaction between a work of art and its observers to a set of biological automatisms. I will challenge such an approach and take up art theory's interest in the historico-cultural and situational dimensions of art experience. Looking at two examples of large-scale installation and sculptural post-war American art, I will explore instable perceptions of depth and changing experiences of space that indicate complex interactions between perceptual and higher cognitive processes. The argument will draw on recent theories describing neuronal processes underlying multistable phenomena, eye movement, visual attention and decision-making. As I will show a large number of neuroscientific studies provide theoretical models that help us analyse not the anthropological constants but the influence of cultural, individual and situational variables on aesthetic experience.

  12. On Clustering during and after Crisis as the Tool for Analyzing the Global Economic Architecture

    Directory of Open Access Journals (Sweden)

    Kobylianska Alla V.

    2017-03-01

    Full Text Available The article is aimed at analyzing the development of global economy from the viewpoint of formation of ideas of its aggregation by means of the cluster analysis. It is found that during 1995-2014 in the world there were about 20 countries which GDP in total amounted to 80% of the global GDP. According to these data Japan, the USA, Germany, China, and Brazil formed a kernel of global economy. Further results of the cluster analysis have allowed to draw conclusions that during the observation period the United States and the Russian Federation remained the main centrodes of global economy. Despite the crisis of 2008, integration of global economy continued, most notably from the viewpoint of monetary indicators. The subsequent researches should be concerned with studying the economic policy directed to the internal economic development, the external relations, and formation of global economic policy, as well as to analyzing economic relations between the identified centrodes and other countries. This will help to understand the reasons of the contemporary global economic integration and to prognosticate its development in the future.

    Burlibaşa, L.

    2005-06-01

    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.

    2014-05-01

    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.

  17. 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.

  18. Software architecture for time-constrained machine vision applications

    Usamentiaga, Rubén; Molleda, Julio; García, Daniel F.; Bulnes, Francisco G.

    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.

    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.

    Full Text Available The adaptation of the forms and phenomena of nature is not a recent concept. Observation of natural mechanisms has been a primary source of innovation since prehistoric ages, which can be perceived through the history of architecture. Currently, this idea is coming to the front again through sustainable architecture and adaptive design. Investigating natural innovations and the clear-outness of evolution during the 20th century led to the creation of a separate scientific discipline, Bionics. Architecture and Bionics are strongly related to each other, since the act of building is as old as the human civilization - moreover its first formal and structural source was obviously the surrounding environment. Present paper discusses the definition of Bionics and its connection with the architecture.
