PURPOSE OF REVIEW: To clarify the causal relationship between migraine and atopic disorders in children and adolescents. RECENT FINDINGS: Migraine headache and atopic disorders including asthma are both common functional syndromes of childhood in which nature of the relationship is still debated. Attacks may induce in both disorders upon exposure to potential triggers in genetically susceptible individuals. Clinical phenotype manifests by temporary dysfunction of target tissue mediated by inflammation triggered by specific agents. Clinical features also change after puberty because of the partial effect of female sex hormones on the process. Appropriate definition of the syndrome and differentiating from other disorders are necessary not only for correct diagnosis, but also for planning of management strategies in children. Allergic rhinosinusitis needs to be differentiated from migraine even in experienced clinics. Questioning the presence of cranial autonomic symptoms is important clue in the differential diagnosis. Atopic disorder screening is particularly required in the diagnosis of migraine in childhood and adolescents. The link between both disorders of childhood seems to be far from a coincidence and some common inflammatory mechanisms are shared. SUMMARY: On the basis of clinical features, laboratory findings and some practical clues in children, accurate diagnosis of migraine and atopic disorders are very critical for physicians, pediatricians and algologists.

Working with colleagues at Princess Sumaya University for Technology (Jordan), German Jordanian University (Jordan), and Mersin University (Turkey), the interdisciplinary team at Bath will aim to improve the living conditions in refugee camps by designing low cost and easy to construct housing that will moderate extremes of temperature and ensure the privacy, comfort and dignity of residents. The three-year project will conduct the largest ever global study investigating thermal, air quality and social conditions in camps housing displaced people. The views of camp occupants and aid agencies such as UNHCR (United Nations High Commissioner for Refugees) on the enhancement of housing and key social issues will be sought as a core element of this study. Aid agencies provide invaluable support and resources for large numbers of displaced people inside camps. However, according to a recent pilot study conducted by the research team, shelter design can create specific problems for inhabitants increasing, in turn, the demands upon humanitarian organisations. For example, health can be undermined when poorly-insulated shelters fail to mediate extremes of temperature and design that doesn't meet the need for privacy and security can harm psychosocial wellbeing. With these findings in view, the researchers will utilize building physics to inform the design of shelters using novel combinations of conventional and non-conventional materials to ensure the shelters naturally stay warm in winter and cool in summer. 20 possible shelter designs will be created, with six designs constructed in the UK to test construction times, and thermally tested in a climate chamber at the University's Building Research Park in Swindon. The most promising of these designs will then be transported to Jordan to test in local conditions and obtain the feedback of camp occupants and aid agencies. The world is currently witnessing the highest ever levels of human displacement with conflicts such as in Syria leading to the creation of a new generation of refugee camps. Whilst camps were originally seen as a short term solution, many across the world exist for years and even decades. As well as Jordan, research will be conducted in refugee camps in three other countries selected to provide as wide a range of climatic, cultural, social and political conditions as possible. At present the team envisage working in Thailand, Turkey and Tanzania. The project will benefit aid agencies such as the UNHCR by creating a manual that explains the benefits of each shelter design, provides guidance on matching design with context, and offers guidelines on construction. Lead investigator and Professor of Low Carbon Design at the University of Bath, David Coley, said: "In recognition of the immense variability in climatic, environmental and socio-cultural conditions, we aim to develop a variety of shelter designs suited to specific locales and the needs of those people who have been displaced. "I visited Jordan in 2015 year during a rock climbing trip and fell in love with the country and the people. The extreme climates experienced by those living in refugee camps inspired me to propose this project which will truly push the boundaries of my research into low energy building design." Co-investigator and Senior Lecturer in the Anthropology of Development at the University of Bath, Dr Jason Hart, commented: "Over the last 20 years I have worked as an anthropologist with refugees in Jordan and the wider Middle East. "I have witnessed firsthand the daily struggles of displaced people to lead dignified lives in difficult conditions, and decent housing can make an immense difference. "I am therefore excited to collaborate with colleagues from the fields of architecture and civil engineering in a process of shelter design that meaningfully engages the views and aspirations of refugees themselves." Princess Sumaya University of Technology (PSUT) in Amman, Jordan collaborated with Bath in the pilot project and will play an important role as the team move to the next, expanded phase. Professor Abdallah Al-Zoubi, Vice President of PSUT said: "It is an honour for us here at PSUT to collaborate with the prestigious University of Bath in this exciting humanitarian project to help refugees in Jordan, especially the Syrians. "Our involvement in the project represents a tiny bit of the greater efforts Jordan is exerting in hosting the unfortunate children of Syria who are actually facing extreme conditions living in the desert. "We hope that the results and outcomes of the project will ease the suffering of refugees and lead to a dignified stay in Jordan before their final short journey back home." The project, entitled 'Healthy Housing for the Displaced', has received £1.5 million funding from the Engineering and Physical Sciences Research Council (EPSRC).

Adhesive bonding is a key joining technology in many industrial sectors including the automotive and aerospace industries, biomedical applications, and microelectronics. Adhesive bonding is gaining more and more interest due to the increasing demand for joining similar or dissimilar structural components, mostly within the framework of designing lightweight structures. When two materials are brought in contact, the proper or adequate adhesion between them is of great importance, so it is necessary to device ways to attain the requisite adhesion strength between similar or dissimilar materials including the different combinations of metallic materials, polymers, composite materials and ceramics. To make adhesion possible, it is necessary to generate intrinsic adhesion forces across the interface. The magnitude and the nature of those forces are very important. From a thermodynamic standpoint the true work of adhesion (or intrinsic property) of the interface create free surfaces from the bonded materials. Adhesion mechanisms have been known to be dependant on the surface characteristics of the materials in question. The intrinsic adhesion between the adhesive and substrates arises from the fact that all materials have forces of attraction acting between their atoms and molecules, and a direct measure of these interatomic and intermolecular forces is surface tension. Atomic/molecular understanding of adhesion should be extremely beneficial in selecting or creating the appropriate materials to attain the desired adhesion strength. In the present paper, the following topics are reviewed in detail: (a) the surfaces or interfaces of similar and dissimilar materials, (b) adhesion or bonding mechanisms in the adhesive joints (c) thermodynamic theory of adhesion: surface tension or surface free energy concepts including the wetting, wetting criteria, wettability, and thermodynamic work of adhesion, (d) dispersion and polar components of surface free energies, and finally (e) effect of surface roughness on wettability or adhesion. © 2012 Elsevier Ltd.

Under the conditions of the pseudospin and spin symmetry, approximate analytical solutions of the Dirac-Morse problem with Coulomb-like tensor potential are presented. The energy eigenvalue equations are found and corresponding radial wave functions are obtained in terms of confluent hypergeometric functions. The energy eigenvalues are calculated numerically in the absence and presence of the tensor potential. We also investigate the contribution of the potential parameters to the energy splitting of the pseudospin and spin doublets. © 2011 Elsevier B.V.

In this paper, we propose a novel technique for unsupervised change detection of multitemporal satellite images using Gaussian mixture model (GMM), local gradual descent, and k -means clustering. Data distribution of the difference image is first modeled by bimodal GMM with changed and unchanged components. The neighborhood data around each pixel form a sample and are modified by the so-called local gradual descent matrix (LGDM), values of which are descending from center toward outside. LGDM visits each sample and causes small variations in pixel values of the sample in an attempt to shift the sample toward the correct Gaussian component center in the feature space. Thus, LGDM decides how much modification to the current sample is necessary for true categorization of the current pixel by later k-means. The motivation behind the proposed approach is twofold. First, a general method that could efficiently explore both local and global changes for unsupervised change detections is needed. Second, unsupervised change detection methods generally use nonsystematic selections of system parameters. Hence, a parameter selection method without using the ground truth image is required for unsupervised methods. The proposed change detection method is tested for both optical and advanced synthetic aperture radar satellite images and compared with the recent works based on the same input set. The proposed method outperforms the others qualitatively and quantitatively. © 2012 IEEE.

In this paper, a new automated approach for the extraction of aboveground circular storage structures from near-nadir very high resolution satellite imagery is proposed. The approach focuses on the cast shadows of the circular structures and splits the boundaries of the shadow regions into curved segments using the chord-to-point distance accumulation technique. Thereafter, the curved segments are tested with newly developed constraints for being a part of a circular structure, and the ones that pass all of the constraints are considered as candidates. The reciprocal relations between the candidate segments are assessed by a developed mutual evidence test, and for the candidates that expose a relation, a robust circle fitting is applied. For the candidates having no such relations, an approach that further validates the circle evidence is developed. The approach consists in introducing regions-of-interest (ROIs) for each candidate segment and applying a circular Hough transform in each ROI, where the parameters of the transform are self-controlled. Experiments performed on 12 challenging Geoeye-1 test images selected from industrial areas reveal that the proposed approach accurately detects aboveground circular structures in complex industrial environments. Besides, the comparison of the results of the proposed approach with the results of two different circle detection approaches verifies the success and the robustness of the approach developed. © 1980-2012 IEEE.

This paper presents a study of the properties and behavior of cement mortar with clinoptilolite which is one of the most common zeolite minerals found in nature. Six mortar mixtures were prepared by replacing the Portland cement with 0%, 5%, 10%, 15%, 20% and 30% clinoptilolite by weight. Test results showed that water demand, soundness and setting times of the cement pastes increased with the increase of clinoptilolite content. Compressive and flexural strength of the mortars containing clinoptilolite were higher than the control mixture. Dry unit weight of the mortars with clinoptilolite was lower than the control mortar. Clinoptilolite replacement decreased water absorption and porosity of the mortars. The control mortar showed less durability to carbonation compared to the mortars made with clinoptilolite at the end of carbonation tests. Freeze-thaw resistance of the mortars containing 5% clinoptilolite was higher than control mortar. The effect of clinoptilolite incorporation on high-temperature resistance seemed to be dependent on amount of clinoptilolite, temperature level, and the cooling method. © 2010 Elsevier Ltd.

In this study, we propose a novel methodology for automated detection of buildings from single very-high-resolution (VHR) multispectral images. The methodology uses the principal evidence of buildings: the shadows that they cast. We model the directional spatial relationship between buildings and their shadows using a recently proposed probabilistic landscape approach. An effective shadow post-processing step is developed to focus on landscapes that belong to building regions. The building regions are detected using an original two-level graph theory approach. In the first level, each shadow region is addressed separately, and building regions are identified via iterative graph cuts designed in two-label partitioning. The final building regions are characterised in a second level in which the previously labelled building regions are subjected to a single-step multi-label graph optimisation performed over the entire image domain. Numerical assessments performed on 16 VHR GeoEye-1 images demonstrate that the proposed approach is highly robust and reliable. A distinctive specialty of the proposed approach is its applicability to buildings with diverse characteristics as well as to VHR images with significantly different illumination properties. © 2013 International Society for Photogrammetry and Remote Sensing, Inc.
