Authors: Taylor Sharonda J. Alston , Peterson Mitchell A. , Garland Beth H. , Hastings Elisabeth S. 
Published: January 2015

Abstract
Background: Adolescent obesity is a chronic disease that is impacted from each patient’s biopsychosocial milieu. Successfully treating pediatric obesity requires long-term, innovative, systematic involvement to facilitate patient and family engagement and change.
Methods: Extensive chart review was done for three obese adolescents who underwent comprehensive weight management in an adolescent clinic seen within the past 5 years. The charts were reviewed starting from the time of initial contact through the last visit in the clinic. The patients are no longer receiving care within the clinic.
Results: The patients presented with BMI>99th percentile, family history of obesity, severe psychosocial stressors, and multiple obesity-related comorbidities. Their treatment involved comprehensive multidisciplinary intervention in an adolescent weight management clinic within a tertiary care center. In addition to rigorous support through frequent office visits, these patients all eventually required temporary, alternative living arrangements to successfully implement recommendations. One patient resided with another family member; two went to inpatient weight management program care for 2–3 months. All subjects successfully lost weight when away from their primary residence, and they demonstrated improvement or resolution of comorbidities.
Conclusions: This case series of three adolescents who underwent comprehensive obesity evaluation and treatment demonstrates multidisciplinary care across interconnected treatment programs and active engagement of family. Those who maintained successful weight loss reduced sedentary time, demonstrated family support (e.g., key members attending follow-up visits), and altered their living environment and were committed to their own health goals.

Published: January 2015

Abstract
Background: Adolescents affected by a severe disease who undergo high-risk treatment may experience stress, pain, extreme frustration, depression, and anger. In this large spectrum of emotions, several situations must be considered carefully. To improve coping and quality of services offered to adolescents in paediatric hospitals, we elaborated a semi-structured interview and a short questionnaire (Quality of life-adolescent-Istituto Giannina Gaslini, QoL-adol-IGG scale) to investigate the quality of life, the needs and expectations of adolescent in-patients.
Methods: The study sample includes 117 in-patients aged between 10 and 20 years coming from several Italian regions who were admitted to the G. Gaslini Research Children’s Hospital for a period of 10 days or more, regardless of the disease. The QoL-adol-IGG scale was administered – after obtaining informed consent from the children and their parents – in one single encounter by trained psychologist. The distribution of the answers was evaluated after stratification by patient’s age, gender, area of residence, and clinical diagnosis. Continuous data were compared using the Kruskal-Wallis, while the χ2-test was used for categorical data.
Results: Seventy-two percent had difficulty practicing normal daily activities during their stay in the hospital, not only because of the disease (40%), but also because of the poor organization within the hospital, the lack of proposals/activities and space for spare time, and the limited access to technologies. Adolescents ≥15 years were more frequently dissatisfied than youngsters concerning the access to Internet and other technologies, the possibility to make new friends and to take part in social activities.
Conclusion: The results of this study, which evaluated the hospital’s organization, but also psychological functioning in a representative sample of patients, may contribute to optimize internal procedures of clinical departments where adolescent in-patients are present, on the basis of their requests and taking into account their age.
Mathematical Characterization of Bénard-Type Geothermal Scenarios Using Discriminated Non-dimensionalization of the Governing Equations
Authors: Cánovas M. , Alhama I. , Alhama F. 
Published: January 2015

Abstract
The classical non-dimensionalization process of governing equations is a low-cost method commonly applied for a first approximation to the dimensionless numbers that determine the solution patterns in many problems; however, this procedure fails in complex problems, where it is not even possible to define reference quantities – because they are not established in the statement of the problem – to make the dependent or independent variables dimensionless. The application of discrimination corrects this obstacle and allows suitable dimensionless groups to be defined. These, in turn, have two interesting properties: (i) they are of order of magnitude unity, and (ii) they have a clear meaning in terms of balance of physical quantities that counteract each other in a domain or sub-domain of the problem. In this paper, discriminated non-dimensionalization is applied to geothermal scenarios of Bénard-type convective flow, large horizontal boundary sides under a temperature gradient in porous media, to determine the dimensionless groups that control the steady temperature and stream patterns and, from these, the order of magnitude of the main unknowns of the problem. The results were checked numerically for many cases.
Application of a multilayer injection molding process for thick-walled optical components
Authors: Hopmann Christian , Röbig Malte 
Published: January 2015

Abstract
Nowadays, the injection molding of optical components is becoming more and more important. A process which constructs the injection-molded part in layers offers considerable potential for productivity increases in the manufacturing of thick-walled optical components. The so-called multilayer injection molding, also known as overmolding technology enables a considerable reduction of the normally long cycle times and improves the optical properties. It is even possible to increase the molding accuracy due to the lower shrinkage potential of the single layers. Contrary to experience, the influence of the mold temperature on the bonding strength is very low. So, the temperature control of the mold can be adapted to the process consideration in regard to optical characteristics.
Regularization method for predicting an ordinal response using longitudinal high-dimensional genomic data
Authors: Hou Jiayi , Archer Kellie J. 
Published: January 2015

AbstractAn ordinal scale is commonly used to measure health status and disease related outcomes in hospital settings as well as in translational medical research. In addition, repeated measurements are common in clinical practice for tracking and monitoring the progression of complex diseases. Classical methodology based on statistical inference, in particular, ordinal modeling has contributed to the analysis of data in which the response categories are ordered and the number of covariates (
Testing the relationships between shadow economy and unemployment: empirical evidence from linear and nonlinear tests
Authors: Saafi Sami , Farhat Abdeljelil , Haj Mohamed Meriem Bel 
Published: January 2015

AbstractThe aim of this paper is to empirically investigate the dynamic linkages between unemployment and shadow economy for 32 developing and developed countries for the period 1980–2009 using parametric and non-parametric techniques. To this end, the Hansen and Seo (2002) threshold cointegration approach and the nonlinear causality test of Kyrtsou and Labys (2006) are applied to assess these relationships. Results obtained clearly do not support the view that unemployment and shadow economy are neutral with respect to each other, except in the case of Bolivia, China, Colombia, Pakistan, Philippines and Portugal, where a neutral relationship is found. We find, however, considerable evidence of bi-directionality in Finland and Sweden. This indicates that high levels of unemployment lead to high levels of shadow economy and vice versa. We also find clear evidence of unidirectional causality running from unemployment to shadow economy in the US, Jamaica and Venezuela which implies that, in these three countries, a faster rate of unemployment promotes a higher share of the underground economy in total GDP. Further, the causality relationship appears to be uni-directional but reversed for Chile. Overall, our findings suggest that policy implications of the unemployment-shadow economy relationships should be interpreted with caution, taking into account the test-dependent and country-specific results.

AbstractA key common feature of all but three known mammalian genera is the strict seven cervical vertebrae blueprint, suggesting the involvement of strong conserving selection forces during mammalian radiation. This is further supported by reports indicating that children with cervical ribs die before they reach reproductive age. Hypotheses were put up, associating cervical ribs (homeotic transformations) to embryonal cancer (e.g., neuroblastoma) or ascribing the constraint in cervical vertebral count to the development of the mammalian diaphragm. Here, we describe a spontaneous mutation c.196A &gt; G in the Bos taurus T gene (also known as brachyury) associated with a cervical vertebral homeotic transformation that violates the fundamental mammalian cervical blueprint, but does not preclude reproduction of the affected individual. Genome-wide mapping, haplotype tracking within a large pedigree, resequencing of target genome regions, and bioinformatic analyses unambiguously confirmed the mutant c.196G allele as causal for this previously unknown defect termed vertebral and spinal dysplasia (VSD) by providing evidence for the mutation event. The nonsynonymous VSD mutation is located within the highly conserved T box of the T gene, which plays a fundamental role in eumetazoan body organization and vertebral development. To our knowledge, VSD is the first unequivocally approved spontaneous mutation decreasing cervical vertebrae number in a large mammal. The spontaneous VSD mutation in the bovine T gene is the first in vivo evidence for the hypothesis that the T protein is directly involved in the maintenance of the mammalian seven-cervical vertebra blueprint. It therefore furthers our knowledge of the T-protein function and early mammalian notochord development.

O estudo objetivou avaliar o desempenho de genótipos de plantas de Eucalyptus urograndis (clone 105 e 433) em relação à tolerância à seca, considerando a análise de crescimento das plantas. Para tanto, plantas foram cultivadas em vasos de 8 litros em casa de vegetação. O delineamento foi em inteiramente casualizado, com quatro tratamentos contendo desesseis repetições. O manejo hídrico foi estabelecido com base em dois potenciais mínimos de água (Ψ): -0,03 e -1,5 MPa, através da pesagem diária dos vasos. O desenvolvimento das plantas foi avaliado em coletas a intervalos de 15 dias, iniciando no momento de plantio da muda no vaso até os 60 dias após plantio. Considerando-se o acúmulo de matéria seca total (MS) e o índice de área foliar da planta (IAF) como base para a determinação dos seguintes índices fisiológicos: razão de área foliar (RAF), taxa assimilatória líquida (TAL), área foliar específica (AFE), taxa de crescimento relativo (TCR) e taxa de crescimento absoluto (TCA). Nas condições do experimento, o clone 105 apresentou menor sensibilidade ao déficit hídrico, o que o qualifica como material genético promissor para ambientes sujeitos a estiagem prolongada. Já em condições em que não há restrição hídrica, os dois clones tiveram comportamento semelhantes. UNITERMOS: Eucaliptus urograndis, índices fisiológicos, potenciais hídricos do solo PEREIRA, M. R.

GROWTH ANALYSIS OF CLONE EUCALIPTUS UNDER HYDRIC STRESS 2 ABSTRACT The aim of this study was to evaluate Eucaliptus grandis genotypes (Clones 105 and 433) in relation to drought tolerance, through growth plant analysis. Black PVC pots with 10 liter volume were used for cultivate plants in polyethilene greenhouse oriented east/west. Completely randonmized design with four treatments was used: two clones and two minimum soil water potentials ( - 0.03 and -1,5 MPa) and sixteen replicates. Pots were weighed daily in order to evaluate water content and characteristic soli water curve was determined. Plant development was obtained each 15 days from planting until 60 days through total dry matter (DM), leaf area index (LAI), leaf area ratio (LAR), net assimilative ratio (NAR), specific leaf area (SLA), relative growth ratio (RGR) and absolute growth ratio (AGR). Results showed that clone 105 presented less sensibility to water deficit, which qualify it as genetic material for use under dry soil conditons. On the other hand, both clones had similar behavior with no water restrictions. KEYWORDS: Eucaliptus grandis, soil water potentials, morphologic measurements.

Published: January 2015

A curva de retenção de água no solo pode ser estimada por diversos métodos, e alguns deles demandam maior tempo para a sua determinação. Assim, o objetivo desse trabalho foi a comparação da curva de retenção de água no solo, determinada pelos métodos de Arya & Paris, câmara de Richards e centrífuga, em um Neossolo Quartzarênico em Petrolina - PE. Nas camadas de 0,00-0,20, 0,20-0,40 e 0,40-0,60 m de profundidade, foram coletadas amostras deformadas em 3 pontos de uma área cultivada com videiras irrigadas, as quais foram homogeneizadas por camada, formando assim uma amostra composta para cada camada; em seguida, tais amostras foram subdividas em três subamostras e cada uma foi encaminhada para a determinação da curva de retenção de água no solo pelos métodos testados. Os resultados obtidos pelo método de Arya & Paris não apresentaram correspondência com os obtidos pelos métodos da centrífuga e da câmara de Richards. No entanto, o desenvolvimento de calibrações específicas do método de Arya & Paris para os solos irrigados do Submédio São Francisco é recomendada, tanto pela possibilidade de uso da curva de retenção de água no solo para o manejo de irrigação, como pelo potencial do método quanto à determinação rápida. UNITERMOS: retenção de água do solo, analisador granulométrico, método. NASCIMENTO, P. dos S.; BASSOI, L. H.; PAZ, V. P. da S.; VAZ, C. M. P.; NAIME, J. de M.; MANIERI, J. M. COMPARATIVE STUDY OF DETERMINING METHODS OF SOIL WATER RETENTION CURVE 2 ABSTRACT Soil water retention curve can be estimated by different methods, and some of them are time consuming. Hence, this research aimed to determine and compare the soil water retention curve, obtained by the methods proposed by Arya & Paris, Richards (pressure membrane apparatus) and centrifuge, of a Typic Quartzipisamment from Petrolina, State of Pernambuco, Brazil. To determine the soil water retention curve in the layers of 0.00-0.20; 0.20-0.40 and 0.40-0.60 m depths, disturbed soil samples were collected in three points of an irrigated vineyard area. The disturbed soil samples were homogenized by layer, thus forming a composed sample for each soil layer. These samples were subdivided into three sub samples, and each one was used to determination of soil water retention curve by the methods tested. The results from method proposed by Arya & Paris did not present similarity with those obtained by Richards´chamber and centrifuge methods. Nevertheless, the development of specific calibration to irrigated soils from Lower-middle São Francisco region is recommended due to the application of soil water retention curve to irrigation scheduling as well as the quickness of the method.

Este trabalho teve como objetivo analisar os parâmetros dimensionais da rede de drenagem através de 12 microbacias de 3a ordem de ramificação, sendo 4 microbacias por unidade de solo (LVA, RL e RQ). A distinção dos solos foi realizada através do teste "t" para verificação dos contrastes ortogonais entre as médias dos três solos e da análise de agrupamentos e de componentes principais. Os resultados permitiram concluir que a análise multivariada não foi eficiente na discriminação dos três solos através das variáveis dimensionais. Essas variáveis isoladamente através do teste "t" permitiram uma diferenciação entre o solo RQ e as unidades LVA e RL, porém não foram sensíveis para os solos LVA e RL.

WATERSHED MULTIVARIANCE ANALYSIS IN RELATION TO SOIL TYPE 2 ABSTRACT The objective of this work was to study the dimensional parameters of the drainage net using 12 third-order ramification hydrological watersheds: 4 watersheds per soil unit (LVA, RL and RQ). The soil distinction was realized using "t" test to verify the orthogonal contrast among three soil averages and the grouping analysis and mean components. The results showed that the multivariance analysis was not able to discriminate three soils using the dimensional analysis. The "t" test of this isolated variable allowed discriminating RQ soil from LVA and RL soil units; but it was not sensitive to discriminate the LVA soil and RL unit.

O girassol é uma planta que se adapta em diversas condições edafoclimáticas, porém, as necessidades hídricas, assim como os coeficientes de cultura nos diferentes estádios fenológicos, ainda não estão perfeitamente definidas. Na região do Arenito Caiuá, Noroeste do Estado do Paraná, por possuir solo extremamente arenoso, portanto com baixa capacidade de retenção hídrica, torna-se imprescindível o cultivo de culturas anuais sob a técnica de semeadura direta. Com objetivo de estabelecer um manejo adequado de irrigação suplementar para a cultura do girassol nesta condição, valores de coeficiente de cultura foram propostos em cinco fases fenológicas. Utilizou-se um delineamento experimental de blocos casualizados com três repetições e cinco tratamentos, sendo um sem irrigação e quatro com lâminas de irrigação embasadas na adoção de diferentes coeficientes de cultura. Ao final de cada fase foram medidas as seguintes componentes de produção: massa seca, diâmetro de capítulo, diâmetro de caule e altura de planta. A maioria das componentes respondeu de maneira linear, independente da fase analisada. Não houve baixa produtividade da cultura do girassol com ausência de irrigação, igual a 2271 kg ha-1, no entanto a maior produtividade, 3063 kg ha-1, foi alcançada por meio da irrigação que utilizou coeficientes de cultura iguais 0,4, 0,8, 1,2, 0,8 e 0,4, nas fases 1,2,3,4 e 5, respectivamente.

SUNFLOWER GROWTH AND YIELD UNDER IRRIGAGATION LEVELS IN NO-TILLAGE SYSTEM IN ARENITO CAIUÁ REGION - PARANÁ STATE. 2 ABSTRACT The sunflower crop adapts various soil and climate conditions, however, the water requirements and the crop coefficients in different growth stages are not yet well defined.In Arenito Caiuá, Northwest of Parana State, because the soil is extremely sandy with low water retention capacity, there is a need for annual crops cultivation under no-tillage technique. In order to establish a proper supplemental irrigation management for sunflower cultivation in this condition, crop coefficient values were proposed in five phases of development. A randomized block design was used with three replications and five treatments, one without and four irrigation depths based in the adoption of different crop coefficients. At the end of each phasethe following yield components were measured: dry matter, capitulum and stem diameter, and plant height. Most components responded in a linearly, independent of the phase analyzed. There wasn’t sunflower low yield without irrigation equal to 2271 kg ha-1, however the highest yield 3063 kg ha-1 was obtained by irrigation which used crop coefficients equal to 0.4, 0.8, 1.2, 0.8 and 0.4 in phases 1,2,3,4 and 5, respectively.
