Childhood cancer: diagnosis impact analysis

A cancer diagnosis significantly impacts both patients and their families, as potential stressors place them in a vulnerable condition. In order to analyze the psycho­social impact of a cancer diagnosis, this study included 12 children aged between 6 and 12 years old ( M = 8.75, SD = 2.05) and their respective caregivers in a hospital located in Grande Vitoria, in the State of Espirito Santo, in Brazil. Coping with hospitalization (Coping with Hospitalization Scale) and psychosocial risk (Psychosocial Assessment To­ol/PAT) were assessed. Socio-demographic and clinical data were obtained through medical records. Data were submitted to descriptive statistical analysis. The psychoso­cial risk of families was at the clinical level. Regarding the need of coping, adaptive strategies were found, such as distraction and social support, as well as less adaptive strategies, such as brooding. This study contributes to the field of coping among chil­dren and indicates potential sources of psychological intervention. Keywords: coping; childhood cancer; psycho-oncology; psychosocial risk; pediatric psychology.
Morphological variability in wing size and wing shape among species Aphidius absinthi Marshall, A. Rosae haliday and A. Urticae Haliday (Hymenoptera: Braconidae: Aphidiinae)

In this paper, we applied traditional and geometric morphometric methods to analyze variability in wing size and wing shape among species Aphidius absinthi Marshall, A. rosae Haliday and A. urticae Haliday. These taxa represent closely related species with different biological and ecological characters. For the morphometric analyses, we used a sample of 52 female specimens that were collected during the period 2009-2013, on different localities in Serbia. Traditional morphometric analyses revealed statistical significance in stigma shape discrimination of analysed taxa. Our geometric morphometric analyses also confirmed that major contribution to the wing shape variation had the changes in length of the radial sector and stigma shape. Combining the traditional and geometric morphometric analyses, we confirmed the validity of the wing characters previously used in taxonomic studies of the genus Aphidius .

Cross-talk between the TonB and TolA Energy Transduction Systems in Escherichia coli

Ray A. Larsen, Advisor The TonB system in Escherichia coli is primarily responsible in providing energy to outer membrane (OM) receptors in order to transport siderophores across the OM and into the periplasm as a means for the cell to acquire iron. The Tol system also provides energy to the OM, ostensibly functioning to maintain membrane integrity. TolA/TonB protein chimeras were made to examine cross-talk between the two systems. While examining cross-talk, specific regions of the TonB protein were determined to be important for energization to occur. While it was known that the transmembrane domain was crucial for energization, data implies that the first 12 residues of TonB also play a significant role in the energization process. A chimera in which the transmembrane domain and the first 12 residues of the N-terminal domain were TolA and the rest of the protein was TonB was able to be energized, and the efficiency at which it worked depended on which components of the TonB and TolA systems were present. A chimera in which only the first 12 residues were TolA and the transmembrane domain and the rest of the protein was TonB did not become energized efficiently, but showed stability no matter which components of the TonB and TolA system were present. An inactive TonB protein is stable in the absence of the other system components, which is one explanation for why the TolA/TonB chimera in which only the first 12 residues are TolA showed stability throughout the study. This data suggested that the first 12 residues of TonB played a crucial role in energizing TonB
Optimum Cell Size for High Order Singular Basis Functions At Geometric Corners

− Both low-order and high-order singular basis functions have been previously proposed for modeling edge singularities in the current and charge densities at geometric corners in electromagnetic integral equation formulations. This paper attempts to identify an optimum dimension for the cells adjacent to corners, as a function of the polynomial degree of the representation used away from the corner cells. The residual error obtained via the solution of an over-determined system of equations is used to judge the relative accuracy of various approaches.
AN ANALGESIC AND ANTI-INFLAMMATORY ACTIVITY OF HYDRO-ALCOHOLIC LEAVES EXTRACTS OF SOME INDIGENOUS HERBS GROWING IN UTTARAKHAND, INDIA

Objective: To study anti-inflammatory and analgesic activities of hydroalcoholic extracts from leaves of Callicarpa macrophylla and Micromeria biflora were evaluated for support to their traditional medicinal applications. Materials and method: The extracts from the leaves of C. macrophylla (CMLE) and M. biflora (MBLE) at 50 and 100 mg/kg body weight were evaluated for anti-inflammatory and analgesic activities in mice. Analgeseic effect characterized by a reduction in the number of writhes induced by acetic acid and anti-inflammatory activity was determined by carrageenan induced paw oedema method. Results: The extracts significantly reduced the formation of oedema induced by carrageenan as well as good analgesic effect. Extracts of C. macrophylla produce significant (p<0.05) anti-inflammatory activity with 28.01 % inhibition in paw volume and followed by M. biflora (20.26%) at a dose level of 100mg/kg body weight after 24 hr of the administration of drugs (samples) in comparison to the control. CMLE showed significant (p<0.05) analgesic activity with 37.75% inhibition in writhing while 35.34% inhibition was observed with MBLE at 100 mg/kg body weight. The extract of C. macrophylla was found to be more potent then M. biflora extracts and activities are dose dependent. Both the plants extract strong anti-inflammatory and analgesic effect in comparison to the control but moderate than standards. Life Sciences
On a topological invariant of finite topological spaces and enumerations

Let T(n) be the number of topologies on a set with n-element. It is an old and difficultproblem to determine this number. Many authors attacked this problem and so far determined this number T(n) for small value n. Recently, M. Erne pronounced that he determined thisnumber T(n) for all n^Yi, by using a new reduction formula [4]. In this paper, we will define a topological invariant which relates to the determination of T{n), investigate its property and make some computations in connection with its invariant rather than intend to determine T{n). If X is a finitetopological space with n-element, then X is determined by the minimal open set Ux containing each of its point x. If UxQUy holds, then we define the relation < by x<y on X. This relation ^ is reflexive and transitive and so (X, <) is a quasi ordered set. Conversely, with a given quasi ordered set (X, <), if we define Ux by Ux={y\y<x}, we can associate the finitetopological space with the minimal base {Ux \x<bX}. This gives a one to one correspondence between all topologies on X and all quasi orders on X, and also induces a one to one correspondence between all To topologies on X and allpartial orders on X [1, p, 28], [2, p. 14], [7, p. 142]. It is also well known that there is a one to one correspondence between all topologies on X and all the labeled transitive digraphs with nelement [5]. Furthermore there is a one to one correspondence between all To topologies on a set with n-element, all finitedistributive lattices L of rank n, all the labeled transitive acyclic digraphs with n-element [5], [11]. Let T0(n) denote the number of all To topologies on a set with n-element. J.W. Evance, F. Harary and M.S. Lynn proved that
Hydrological Changes After the Last Ice Retreat in Northern Poland Using Radiocarbon Dating

A simplified model of hydrological changes during the Late Glacial and Holocene is presented for the northern Polish regions that were ice covered during the Last Glacial. This reconstruction is based on a group of 197 radiocarbon dates from about 120 localities reflecting the sequence of alternating lake transgressions and regressions. The earliest transgressions were related to dead-ice melting (sometimes in 2–3 phases), while the later ones started during more humid phases. However, these were usually followed by regressions, which may have been connected with the formation of new drainage systems and with the overgrowing of shallow lakes by peat bogs.

CFD Study of Liquid Sodium inside a Wavy Tube for Laminar Convectors: Effect of Reynolds Number, Wave Pitch, and Wave Amplitude

Metallic tubes have been widely used as primary heat transfer elements in laminar convectors for domestic and aerospace heating purpose. This paper uses CFD tool to investigate the heat output and pressure drop of liquid sodium flowing inside a circular tube having a wavy profile throughout its length. The wavy tube can be utilized in laminar liquid metal convectors as basic heat transfer element. The effect of Reynolds number () wave pitch () and wave amplitude () on the heat output and pressure drop has been numerically studied. Based on the CFD results important controlling parameters have been identified and it is concluded that the heat output from the wavy tube is affected by the wave pitch and the wave amplitude while the pressure drop is mostly affected by the Reynolds number and wave amplitude.
Mediation Effect of Knowledge Management Enablers on the Relationship between Organizational Characteristics and Entrepreneurial Orientation

The main aim of this study is to investigate the mediating effect of knowledge management enablers between the organizational characteristics and entrepreneurial orientation of employees. The study considered three constructs, namely: Knowledge management enablers, organizational characteristics and entrepreneurial orientation, to formulate the framework for this research. A quantitative approach was adopted in the study. Data were collected through a web-based online survey. The population of the survey was estimated to be around 300 employees from three cement manufacturing organizations in the state of Johor, Malaysia. A 70.4 per cent response rate was achieved. Five hypotheses were formulated and tested in the study. A simple multiple regression was used to analyse the data. All five hypotheses were supported, confirming that there is a partial mediation by the knowledge management enablers, as well as by the corresponding dimensions between organizational characteristics and entrepreneurial orientation. In addition, the implications of this study are also discussed, apart from the avenues for future research in the area of entrepreneurial orientation.
Respite Care and Marital Quality in Parents of Children with Down Syndrome

Respite Care and Marital Quality in Parents of Children with Down Syndrome Michelle Norton Department of Counseling Psychology and Special Education, BYU Educational Specialist Parents of a child with a disability are at greater risk than other couples for having higher stress, adjustment difficulties, and lower marital quality. Respite care has been shown to reduce stress in parents of children with disabilities. This study focused on parents who have a child with Down syndrome and their reported marital quality and respite care received. One hundred and twelve couples, each consisting of a mother and a father who lived with their child with Down syndrome, completed questionnaires including the Revised Dyadic Adjustment Scale, Experience in Close Relationships Questionnaire, Daily Hassles and Uplifts Scale, and a respite questionnaire. Results were mixed. Respite care did not predict marital quality for either wives or husbands. However, respite hours was related to wife stress, which was in turn related to wife marital quality. Respite hours was also related to husband stress, which was related to husband marital quality. In addition, wife uplifts was directly related to wife marital quality and to husband marital quality. Husband uplifts was related to husband marital quality. While not directly predicting marital quality, respite care was indirectly related to increases in marital quality through stress. Therefore, it is important that respite care be accessible and provided to parents who have a child with Down syndrome. Recommendations for policy makers and researchers are offered.
The monetary transmission mechanism at the euro-area level: issues and results using structural macroeconomic models

This paper addresses some of the issues faced by macroeconomic model builders in analysing the monetary transmission mechanism. These include the sensitivity of the policy simulation results to changes in the monetary and fiscal policy rule and the introduction of forward-looking behaviour in the model. To illustrate the importance of these issues the paper reports the results of variant monetary policy simulations at the euro-area level using the AWM and NiGEM models JEL Classification: C50, C52, E5
Definition of airworthiness categories for civil unmanned aircraft systems (UAS)

This paper introduces a novel strategy for the specification of airworthiness certification categories for civil unmanned aircraft systems (UAS). The risk-based approach acknowledges the fundamental differences between the risk paradigms of manned and unmanned aviation. The proposed airworthiness certification matrix provides a systematic and objective structure for regulating the airworthiness of a diverse range of UAS types and operations. An approach for specifying UAS type categories is then discussed. An example of the approach, which includes the novel application of data-clustering algorithms, is presented to illustrate the discussion.
Forest gaps, edge, and interior support different ant communities in a tropical peat-swamp forest in Borneo

Southeast Asia’s tropical peat-swamp forests (TPSF) are globally important for carbon storage and biodiversity conservation, but are at risk from multiple threats and urgently require improved management. Ants are often used as ecological indicators in monitoring programmes to guide adaptive management, but data on TPSF ants are scarce. We conducted a twelve-month study on ants in the Sabangau TPSF in Indonesian Borneo using baited traps, to compare community composition across three disturbance categories (forest gaps, forest edge and relatively undisturbed interior forest) and between dry and wet season. The three disturbance categories supported distinct ant communities across seasons. Differences in canopy cover likely underlie these changes in ant community composition. Surveying was more effective in the dry season, because ant capture rates were higher and more indicator taxa were identified than in the wet season, but overall ant community composition did not differ significantly between seasons. These findings suggest a potentially useful role of ants as ecological indicators in TPSF. Further surveys should be conducted in Sabangau and other TPSFs to test the transferability of our findings.
Foraging behaviour of Myotis mystacinus and M. brandtii in relation to a big road and railway in south-central Sweden

Roads and railways are increasing worldwide. One taxa that is affected by this is bats. Bats are directly killed by vehicles and experience behavioural changes around roads and railways. There are different mitigation measurements to help bats cross roads safely, including different over- and underpasses. One genus of bats that has been shown negatively affected by roads and railways in many areas is Myotis. In this study we examined the behaviour of two Myotis species: M. mystacinus and M. brandtii. We tested the hypothesis that large roads and railways crossing a forest dominated area act as barriers for these species and that they would use over- and underpasses to cross the road and railway safely. To study this, we conducted an autobox survey and radio-tracked individual bats. We had no recordings or direct observations where bats crossed the road or railway directly. We did, however, observe bats using both over- and underpasses. Our results suggest that large roads and railways act as barriers for M. mystacinus and M. brandtii, in the sense that they avoid crossing the road and railway. We can conclude that these species use mitigation measurements, such as over- and underpasses, in areas where they are available. It is therefore important to include these mitigation measurements when constructing new roads and railways.
Engineering of a Benzodiazepine binding site into GABAA receptors composed of alpha1 and beta3 subunits

GABAA Rezeptoren sind die wichtigsten inhibitorischen Neurotransmitter Rezeptoren des Saugetier Gehirns, und werden durch GABA (γ-Aminobuttersaure) aktiviert. Zahlreiche klinisch relevante Wirkstoffe wie Benzodiazepine, Barbiturate, Anasthetika konnen neben GABA an den GABAA Rezeptor binden und seine Wirkung modulieren. Obwohl diese Wirkstoffe in der Medizin eine breite Anwendung finden, ist die genaue Struktur der Bindungsstelle nicht bekannt. Dies macht ihn zu einem hoch interessanten Untersuchungsgegenstand der Neurobiologie. GABAA Rezeptoren bestehen aus funf Untereinheiten. Die Mehrheit der Rezeptoren sind aus einer gamma (γ), zwei alpha (α), und zwei beta (β) Untereinheiten zusammengesetzt, wobei die hoch affine Bindung von Benzodiazepinen das Vorhandensein einer gamma Untereinheit voraussetzt. Jede Untereinheit hat per Definition eine plus und eine minus Seite. Die Benzodiazepin Bindungstelle befindet sich im extrazellularen Bereich zwischen der α-plus und der γ-minus Seite dieser Untereinheiten. Das Ziel dieser Arbeit war es, eine hoch affine Benzodiazepin Bindungsstelle in einen α1β3 Rezeptor einzubauen, der im Gegensatz zu einem α1β3γ2 Rezeptor keine solche besitzt. Der α1β3 Rezeptor besteht aus zwei α und drei β Untereinheiten. Der Reihe nach wurden wichtige Aminosauren der γ-minus Seite (eines α1β3γ2 Rezeptors) in die β-minus Seite des α1β3 Rezeptors eingebaut. Diese Aminosauren wurden mittels eines in unserem Labor entwickelten strukturellen Modells der Diazepam-gebundenen Benzodiazepin Bindungsstelle und mittels bereits publizierter Artikel ausgewahlt. Die Affinitat von Benzodiazepinen wurde durch Radioliganden-Bindungsstudien an Membranen von HEK Zellen bestimmt die mit den entsprechenden Rezeptoren transfiziert worden waren. Die erhaltenen Resultate lassen darauf schliesen, dass vier Mutationen (β3DGE) ausreichten, um eine hochaffine Benzodiazepin Bindungsstelle in die α1β3 Rezeptoren einzubauen. Die pharmakologische Charakterisierung wurde mittels einer zwei Elektroden Spannungsklemme in Xenopus laevis Oozyten vorgenommen. Die Ergebnisse zeigen, dass sich die durch Flurazepam und Ro15-1788 ausgeloste Modulation der GABA Strome der rekombinanten Rezeptoren α1β3DG (dreifach Mutante) und α1β3DGE von der des Wildtyp α1β3 Rezeptors unterscheidet.
Simultaneous Skeletonization and Topologic Decomposition for Digital Shape Reconstruction

Analyzing the structure of 2D shapes has been studied intensively in recent years. It is a key aspect in various computer vision and computer graphics applications. In this paper, a new algorithm is proposed which efficiently computes a skeleton and a corresponding decomposition of an arbitrary shape. Given the Voronoi diagram, the pruning step has linear complexity. The skeleton is a sparse 1D representation which captures the topology as well as the general structure of a shape. Considering the Voronoi diagram of the boundary vertices, the skeleton is extracted as a subset of the Voronoi edges using a simple classification scheme. A parameter allows to control the skeleton’s sensitivity to perturbations in the boundary curve. The dual Delaunay triangulation yields a topological decomposition of the shape that is consistent with the skeleton. Each part can be classified as belonging to one of three base types which have some interesting properties. The method has been successfully implemented and evaluated. The presented concepts can also be applied to manifold surfaces which is particularly useful for digital shape reconstruction as it is shown at the end of this paper.
Stability of Haskap Berry (Lonicera Caerulea L.) Anthocyanins at Different Storage and Processing Conditions

The effect of freezing, frozen storage (–18 °C for 6 months), thawing, juice extraction, and hot-air drying on the anthocyanin profile of haskap berry (Lonicera caerulea L.) was investigated using RP-HPLC. Five anthocyanins (ANCs) were quantified: cyanidin 3,5-di-glucoside (4.27 % of the total ANCs), cyanidin 3-glucoside (89.39 %), cyanidin 3-rutinoside (2.07 %), pelargonidin 3-glucoside (0.83 %), and peonidin 3-O-glucoside (3.44 %). Freezing did not significantly affect the content of individual ANCs, while frozen storage resulted in significant reductions (16.00-24.50 %). Thawing the frozen berries in the microwave oven retained the highest content of different ANCs. The highest degradation, however, occurred while thawing at room temperature. Extracting juice from the berries significantly reduced the content of individual ANCs. Drying the berries to 25 % moisture content at 60, 100, and 140 oC reduced the individual ANCs by 73.85-76.19, 78.46-80.95 and 90.77-95.40 %, respectively. The overall stability of the five ANCs during storage and processing is summarized by the following trend (from most to least stable): peonidin 3-O-glucoside > pelargonidin 3-glucoside > cyanidin 3,5-diglucoside > cyanidin 3-rutinoside > cyanidin 3-glucoside.
