Published: August 2017

Small fault ahead of the tunnel face in coal roadway is the important hidden hazard factor of coal and gas outburst accidents. The study of small fault prediction has important practical significance, which is the urgent demand of coal mine safety production. The diffraction of breakpoint can be used to identify the fault. However, unlike surface seismic exploration, the diffraction is with approximately horizontal incidence when the advanced detection is carried out in the roadway. The common advanced detection system is mainly as the reference of traffic tunnel, without considering the influence of low-velocity coal seam. Considering the influence of an acoustic wave of the roadway cavity and channel wave of the coal seam, the advanced detection model of small fault ahead of tunnel face is established. Diffraction advanced observation system in which sources located in front of tunnel face is constructed, and the numerical calculation of the high-order staggered-grid finite difference is carried out. The simulation results show that: Compared with the data collected by reflection observation system, in seismic records acquired by diffraction observation system, the suppression effect of acoustic wave is appeared. The diffracted P-wave of the breakpoint of component X is clear with strong energy and short-wave group. Multiple diffractions of the breakpoint are not found, but the multiple diffraction of tunnel face endpoint is obvious. The difference between breakpoint diffraction and multiple diffractions of the endpoint is clear, and diffracted P-wave of the breakpoint is easy to identify. The multiple reflected channel wave between the fault and the tunnel face is very obvious, and the reflected channel wave of small fault is so hard to identify. Migration results show that the imaging resolution of diffracted P-wave of small fault is higher than the reflected channel wave, and breakpoint location of imaging is consistent with the actual model.

Objetivo Investigar la autoestima, la imagen corporal y la depresión en adolescentes en diferentes estados nutricionales.Métodos Participaron en la investigación 418 adolescentes de 14 a 18 años. Se utilizaron cuatro cuestionarios: Caracterización; Inventario de Depresión Infantil; Escala de Autoestima; Escala de Siluetas. El estado nutricional se clasificó utilizando el Índice de Masa Corporal (IMC).Resultados Los niños tenían una mayor prevalencia de sobrepeso y obesidad, menor depresión y insatisfacción corporal y mayor autoestima que las niñas (p<0,001). La depresión se relacionó negativamente con la autoestima (p<0,01), que también se asocia negativamente con la insatisfacción corporal (p<0,01). Aunque los adolescentes de mayor estatus nutricional estaban más insatisfechos (p<0,001), el IMC se relaciona con la insatisfacción corporal sólo para niñas (p<0,01). Para los niños la relación entre la depresión y la insatisfacción corporal fue negativa (p<0,01) y para las niñas fue positiva (p<0,01).Conclusión Adolescentes con sobrepeso y obesos tenían una mayor insatisfacción corporal. La depresión y la autoestima están asociados con la imagen corporal, pero no al índice de masa corporal, lo que demuestra que las subjetividades de los adolescentes deben ser valoradas. Las diferencias observadas entre los sexos deben ser mejor investigadas.

ABSTRACT Background: The treatment of neuroblastoma is dependent on exquisite staging; is performed postoperatively and is dependent on the surgeon’s expertise. The use of risk factors through imaging on diagnosis appears as predictive of resectability, complications and homogeneity in staging. Aim: To evaluate the traditional resectability criteria with the risk factors for resectability, through the radiological images, in two moments: on diagnosis and in pre-surgical phase. Were analyzed the resectability, surgical complications and relapse rate. Methods: Retrospective study of 27 children with abdominal and pelvic neuroblastoma stage 3 and 4, with tomography and/or resonance on the diagnosis and pre-surgical, identifying the presence of risk factors. Results: The mean age of the children was 2.5 years at diagnosis, where 55.6% were older than 18 months, 51.9% were girls and 66.7% were in stage 4. There was concordance on resectability of the tumor by both methods (INSS and IDRFs) at both moments of the evaluation, at diagnosis (p=0.007) and post-chemotherapy (p=0.019); In this way, all resectable patients by IDRFs in the post-chemotherapy had complete resection, and the unresectable ones, 87.5% incomplete. There was remission in 77.8%, 18.5% relapsed and 33.3% died. Conclusions: Resectability was similar in both methods at both pre-surgical and preoperative chemotherapy; preoperative chemotherapy increased resectability and decreased number of risk factors, where the presence of at least one IDRF was associated with incomplete resections and surgical complications; relapses were irrelevant.

ABSTRACT Background: The colorectal neoplasm is the fourth most common malignancy among males and the third among females. In the Western world is estimated that 5% of the population will develop it, making this disease a major public health problem. Aim: To analyze the prevalence of the polymorphism -765G / C region of the COX-2 gene in colorectal cancer patients compared to a control group, analyzing the possible association between this polymorphism and susceptibility to colorectal cancer. Method: This is a case-control study with 85 participants. Were selected 25 with colorectal cancer (case group) and 60 participants without colorectal neoplasia (control group). The molecular genetic analysis was perform to identify the polymorphism -765G / C COX2 gene with standard literature technique. In addition, patient’s clinical and pathological data were analyzed. Results: There was a light increase in prevalence between men in the case group, although this difference was not statistically significant. The results showed a high prevalence of GC and CC genotype in individuals with colorectal cancer, demonstrating an association between the presence of the polymorphism in the COX2 gene and susceptibility to colorectal cancer in this pattern (p=0.02). Similarly, there was also difference in allele frequencies in the groups. When patients with cancer were separated by tumor location, there was a higher prevalence of polymorphism in the left colon (p=0.02). Conclusion: The polymorphism in the COX2 gene is associated with increased susceptibility to colorectal cancer, specially rectosigmoid tumors.

Published: August 2017

Abstract This study aimed to investigate the influence of a three-dimensional cell culture model and bioactive glass (BG) particles on the expression of osteoblastic phenotypes in rat calvaria osteogenic cells culture. Cells were seeded on two-dimensional (2D) and three-dimensional (3D) collagen with BG particles for up to 14 days. Cell viability and alkaline phosphatase (ALP) activity was performed. Cell morphology and immunolabeling of noncollagenous bone matrix proteins were assessed by epifluorescence and confocal microscopy. The expressions of osteogenic markers were analyzed using RT-PCR. Mineralized bone-like nodule formation was visualized by microscopy and calcium content was assessed quantitatively by alizarin red assay. Experimental cultures produced a growing cell viability rate up to 14 days. Although ALP activity at 7 days was higher on BG cultures, cells on 3D and 3D+BG had an activity decrease of ALP at 14 days. Three-dimensional conditions favored the immunolabeling for OPN and BSP and the expression of ALP and COL I mRNAs. BG particles influenced positively the OC and OPN mRNAs expression and calcified nodule formation in vitro. The results indicated that the 3D cultures and BG particles contribute to the expression of osteoblastic phenotype and to differentiated and mineralized matrix formation.

Abstract Anterior open bite (AOB) has a multifactorial etiology caused by the interaction of sucking habits and genetic factors. The aim of this study was to evaluate the association between AOB and polymorphisms in genes that encode Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs). Four hundred and seventy-two children that presented at least one sucking habit were evaluated. Children were examined clinically for the presence of AOB. Genomic DNA was extracted from saliva. Genotyping of the selected polymorphisms in MMP2, MMP3, MMP9, TIMP1 and TIMP2 was carried out by real-time PCR using the TaqMan method. Allele and genotype frequencies were compared between the groups with and without AOB using the PLINK® software in a free and in a recessive model using a chi-square test. Logistic regression analysis was implemented (p≤0.05). Two hundred nineteen children had AOB while 253 did not. The polymorphism rs17576 in MMP9 was significantly associated with AOB (p=0.009). In a recessive model GG genotype was a protective factor for AOB (p=0.014; OR 4.6, 95%CI 1.3-16.2). In the logistic regression analysis, none of the genes was associated with AOB. In conclusion, the polymorphism rs17576 (glutamine for arginine substitution) in MMP9 was a protective factor for AOB.

Abstract This study aimed to determine the influence of maternal factors on the early development of dental caries in Brazilian preschoolers. This cross-sectional study was nested in a cohort of adolescent mothers. The current wave was performed when the children were aged 24 to 42 months. The questionnaire-based survey targeted adolescent mothers and included demographic and socioeconomic variables as well as the maternal education level. In addition, clinical examinations were performed on the mothers and their children. Mothers were assessed for decayed, missing and filled teeth in the permanent dentition (DMFT index) and gingival assessment; their children were assessed for decayed, missing and filled teeth in the deciduous dentition (dmft index). Poisson regression with robust variance was used to estimate the prevalence ratio, risk ratio and 95% confidence intervals. This data was also used to identify the maternal risk factors associated with the outcomes (prevalence and severity of childhood caries). A total 538 mother-child dyads were evaluated; the prevalence of early childhood caries was 15.1% and maternal caries was 74.4%. After the adjustment, the children that exhibited a greater incidence of dental caries were from mothers of low socioeconomic status, or from those presenting decayed teeth and higher rates of gingival bleeding. The results of this study suggest that the oral health of mothers is a potentially important risk factor for the development of early childhood dental caries. Public health planners should consider this information when planning interventions in order to prevent the occurrence of early dental caries.

Abstract The aim of this study was to evaluate the surface free energy (SFE), wetting and surface properties as well as antimicrobial, adhesion and biocompatibility properties of diamond-like carbon (DLC)-coated surfaces. In addition, the leakage of Escherichia coli through the abutment-dental implant interface was also calculated. SFE was calculated from contact angle values; R a was measured before and after DLC coating. Antimicrobial and adhesion properties against E. coli and cytotoxicity of DLC with human keratinocytes (HaCaT) were evaluated. Further, the ability of DLC-coated surfaces to prevent the migration of E. coli into the external hexagonal implant interface was also evaluated. A sterile technique was used for the semi-quantitative polymerase chain reaction (semi-quantitative PCR). The surfaces showed slight decreases in cell viability (p<0.05), while the SFE, R a, bacterial adhesion, antimicrobial, and bacterial infiltration tests showed no statistically significant differences (p>0.05). It was concluded that DLC was shown to be a biocompatible material with mild cytotoxicity that did not show changes in R a, SFE, bacterial adhesion or antimicrobial properties and did not inhibit the infiltration of E. coli into the abutment-dental implant interface.

Published: August 2017

Abstract Psidium cattleianum (PC) has been displaying inhibitory effect against a variety of microorganisms, but this effect has not yet been tested against endodontic pathogens. The aim of this study was to evaluate the antimicrobial activity and biocompatibility of the aqueous (PCAE) and hydroethanolic (PCHE) extracts from Psidium cattleianum (PC) leaves. Minimum inhibitory concentration (MIC) and minimum lethal concentration (MLC) were determined using the microdilution broth method in order to analyze the antimicrobial effect against Enterococcus faecalis, Pseudomonas aeruginosa, Actinomyces israelii and Candida albicans in planktonic conditions. Biofilm assays were conducted only with the extracts that were able to determine the MLC for microorganisms in planktonic conditions. Immediate and late tissue reactions against PC extracts were evaluated using edemogenic test and histological analysis of subcutaneous implants in Wistar rats. The results showed that the MIC and MLC values ranged between 0.25 and 4 mg/mL. The MLC obtained for PCHE inhibited 100% growth of all the tested strains, except for C. albicans. PCAE had the same effect for E. faecalis and P. aeruginosa. Both PC extracts were able to eliminate E. faecalis biofilms and only the PCHE eliminated P. aeruginosa biofilms. The positive controls inhibited the growth of all tested strains in MIC and MLC essays, but no CHX tested concentrations were able to eliminate A. israelii biofilm. PCAE caused a discrete increase in the edema over time, while PCHE caused a higher initial edema, which decreased progressively. Both PCAE and PCHE extracts were biocompatible, but PCHE showed better results with slight levels of inflammation at 28 days. In conclusion, PCHE was biocompatible and presented better antimicrobial effect against important pathogens associated with persistent endodontic infections

Published: August 2017

Abstract Conservative approach, including occlusal splint therapy, is the first option to treat temporomandibular disorders (TMD), because of its reversibility. The present study analyzed the effect of the articular disc position and occlusal splints use on the stress distribution on this disc. A two-dimensional (2D) finite element (FE) model of the temporomandibular joint with the articular disc at its physiologic position was constructed based on cone-beam computed tomography. Three other FE models were created changing the disc position, according to occlusal splint use and anterior disc displacement condition. Structural stress distribution analysis was performed using Marc-Mentat package. The equivalent von Mises stress was used to compare the study factor. Higher stress concentration was observed on the intermediate to anterior zone of the disc, with maximum values over 2MPa. No relevant difference was verified on the stress distribution and magnitude comparing disc positions and occlusal splint use. However, there was stress reduction arising from the use of the occlusal splints in cases of anterior disc displacement. In conclusion, based on the generated FE models and established boundary conditions, the stress increased at the intermediate zone of the TMJ disc during physiological mandible closure. The stress magnitude was similar in all tested situations

Abstract The aim of this study was to conduct a retrospective evaluation of the survival and success rates of dental implants with acid-etched surfaces after 8-10 years of function. Forty-four patients who received 183 implants 8-10 years ago were evaluated. Clinical examinations were performed around the implants and natural teeth. The following parameters were measured: visible plaque index (VPI), marginal bleeding index (MBI), probing depth (PD), bleeding on probing (BOP) and clinical attachment level (CAL). To considerer an implant as a success case, the following criteria were considered: absence of peri-implant infection and suppuration, absence of implant mobility, absence of persistent pain and dysesthesia and absence of radiolucency around the implant. Overall, 178 implants were categorized as surviving (97.3%), 155 were categorized as successful (84.7%), 5 implants (2.7%) were lost (1 in the maxilla and 4 in the mandible), and 3 implants were not under functional load (2.0 %). 20 implants were diagnosed with peri-implantitis. Thus, the survival rate was 97% and the success rate was 85%. In conclusion, implants with acid-etched surfaces showed high survival and success rates after a period of 8 to 10 years of function.

Published: August 2017

ABSTRACT: Wood is the primary energy source for grains and Tobacco drying in the Rio Pardo Watershed (RPW). The amount of firewood produced in the RPW is not enough to supply the demand. Recently, an automatized supply system was introduced in the region enabling the use of sawdust and pellets. In this context, this study aims to compare firewood, sawdust and pellets as energy sources for Tobacco curing in air-forced curing systems. Energetic density was used to estimate the biomass consumption in Tobacco curing. The consumption of biomass is lower for pellet, followed by firewood and sawdust. Pellets and sawdust could complement firewood in the region; however, research is necessary to ascertain the economic feasibility.
Trigeminismo supraventricular em um cão com doença mixomatosa da valva mitral
Authors: Soares Frederico Aécio Carvalho
Published: August 2017

RESUMO: O trigeminismo supraventricular é um distúrbio incomum de formação do impulso elétrico cardíaco. Detectar e tratar arritmias cardíacas são um importante objetivo terapêutico em cardiologia. O objetivo desta nota é relatar a ocorrência de trigeminismo supraventricular em um cão com doença mixomatosa da valva mitral (DMVM). Um cão sem raça definida, macho, inteiro, 15 anos de idade e 13kg foi levado para avaliação cardíaca com um histórico de sopro cardíaco, tosse, dispneia e ascite. Os achados ecocardiográficos foram compatíveis com doença mixomatosa de valvas mitral e tricúspide com comprometimento hemodinâmico severo. A eletrocardiografia (ECG) revelou arritmia sinusal com presença de complexos supraventriculares prematuros isolados, aos pares e períodos de trigeminismo supraventricular. O trigeminismo supraventricular não é relatado em estudos retrospectivos e prospectivos que avaliaram arritmias cardíacas em um grande número de cães. O presente relato evidencia que o trigeminismo supraventricular pode ocorrer em cães com DMVM e comprometimento hemodinâmico severo, provavelmente relacionado à dilatação atrial. Ainda, reforça a importância da realização do ECG em cães com DMVM, complementando as informações ecocardiográficas e possibilitando uma melhor abordagem terapêutica.

Published: August 2017

ABSTRACT: This work aimed to evaluate the effects of the products Biogermex®, Agro-mos®, Soil-Set® and Planta Clean® on the development of white muscardine in Bombyx mori. Products have been tested at two stages for effects on biology of caterpillars and on silk production (1), and then they were evaluated to know their potential in the prevention/control of white muscardine (2). Products were sprayed on mulberry leaves (preventive treatment) and also on the integument of silkworms (curative treatment). At the first stage, the products were applied on four consecutive days, in one of the daily feeds. Planta Clean® - curative treatment - and Soil-Set® - preventive treatment - caused mortality in 63.3% and 30% of silk worms, respectively. The fungus Beauveria bassiana was inoculated at the concentration 5 × 107 conidia/mL on the leaves and insects. The products were applied three hours after application on the fungus, in a single application, and also for four days in the other groups. A group of silkworms sprayed only with the fungus served as control. Biogermex® - curative treatment applied once and for four times - was the most effective, reducing mortality by 25 and 26.7%, respectively, as compared with the control group. None of the evaluated products acts preventively against white muscardine.

Authors: Alves Luis Francisco Angeli , Martins Claudecir Castilho , Nardelli Margaret Seghetto , Alves Victor Michelon
Published: August 2017

ABSTRACT: Diatomaceous earth (DE) is an inert powder obtained from milling the fossilized deposits of diatoms. Mainly composed of silica dioxide, DE is highly hygroscopic and is recommended for use in poultry houses as an evironmental conditioner, with a secondary action being the reduction of lesser mealworm populations Alphitobius diaperinus (Panzer). This study aimed to characterize and assess the insecticidal activity of a new environmental conditioner for poultry houses (Poultry Sec®, Vet Science Bio Solution, Maringá, Paraná, Brazil) in the laboratory. The study was conducted by adding DE to poultry feed (1, 2 and 3 g DE/kg feed), as well as by applying the DE to the poultry litter (86 and 172 g DE/m2), with A. diaperinus adults (26°C in the dark for 10 days). DE samples were analyzed by optical microscopy to measure and count the frustules and to identify the genera of the components. The insecticidal action of the product was observed. When applied to the litter, the DE caused between 83 and 85% mortality. With respect to the qualitative analysis of the diatoms, we estimated the concentration of 1.2 × 106 individuals/g of the product, distributed in nine distinct genera, with Brachysira Kützing being the predominant genus (40%).

Abstract Green banana flour shows good potential as a functional ingredient for special-purpose foods, but there are no data in the literature concerning the use of a green banana pulp and peel flour for the development of products such as pasta. The aim of the present study was to develop tagliatelle pasta substituting the wheat flour with different concentrations of a green banana mixed pulp and peel flour. The pasta formulations were prepared replacing the wheat flour by the green banana mixed pulp and peel flour in two concentrations: 15% and 30%. A control formulation with wheat flour was also prepared. The green banana mixed pulp and peel flour presented higher ash, total fibre and total phenolic compound contents than traditional wheat flour. The pasta formulation with the addition of 15% green banana flour showed the highest ash content and the best sensory acceptability of all the formulations. It was concluded that it was possible to develop a tagliatelle pasta with satisfactory acceptance replacing the wheat flour by a green banana mixed pulp and peel flour.

RESUMO Este estudo objetivou caracterizar aspectos relacionados à dispersão de propágulos de Myrceugenia euosma (O. Berg) D. Legrand (Myrtaceae) em um fragmento de Floresta Ombrófila Mista em Urupema, SC. Para isso, foram avaliados 29 indivíduos reprodutivos quanto à frequência de visitantes, chuva de propágulos, remoção e caracterização de frutos. Registraram-se 140 visitas de pássaros, sem ocorrência de período preferencial. As espécies com maior frequência de visita e maior consumo de frutos foram Zonotrichia capensis (tico-tico) e Stephanophorus diadematus (cabeça-de-velho), consideradas potenciais dispersoras. A frequência de coletores contendo propágulos de M. euosma diminuiu com o aumento da distância, apresentando comportamento distinto em função do tipo de propágulo avaliado. Também foram verificadas sementes intactas junto às fezes das aves nos coletores. A taxa de remoção de frutos depositados no chão foi de 22%, isso demonstra a relevância desse tema no processo de dispersão das espécies, merecendo atenção na realização de estudos futuros.

O presente estudo apoiou-se em variáveis de segmentação econômica, psicográfica e no conhecimento ecológico dos usuários. Para tanto, foram aplicados 100 questionários, contendo perguntas divididas em duas partes: 1) indicação da disposição a pagar pelos usuários do parque; 2) segmentação, segundo determinados critérios e caracterização dos usuários. Os resultados indicaram não somente que as pessoas com perfil altruísta e mais preocupadas com o meio ambiente apresentaram maior disposição a pagar pela conservação do Parque Olhos D’Água, como também que este segmento de usuários poderia contribuir para a definição do perfil do usuário verde e, com isso, servir de base para a elaboração de um programa de marketing ambiental orientado para o incremento dos recursos financeiros necessários para as ações de preservação e melhoria do referido parque.

RESUMO A destinação dos resíduos de serviços de saúde (RSS) representa uma discussão ampla e polêmica, e o momento de revisão da resolução da diretoria colegiada n.º 306/2004, da Agência Nacional de Vigilância Sanitária (ANVISA), é oportuno para ampliar esse debate. Nesse contexto, este artigo buscou, por meio da revisão de publicações científicas, subsidiar escolhas que favoreçam a sustentabilidade ambiental e a proteção da saúde humana na destinação dos RSS. Foram realizadas pesquisa bibliográfica, em âmbitos nacional e internacional, e a revisão de instrumentos legais que regulam a destinação dos RSS no Brasil. As resoluções da ANVISA (n.º 306/2004) e do Conselho Nacional do Meio Ambiente (n.º 358/2005) mostram que a disposição final dos RSS do subgrupo A4 pode ser feita em local licenciado para receber RSS, sem tratamento prévio. Diversas publicações científicas apontam para a falta de evidências quanto à existência de riscos aumentados para o ambiente e à saúde humana dos RSS se comparados aos resíduos sólidos domiciliares e explicam que ambos poderiam ter destinação final com base nos mesmos requisitos. A segregação dos RSS de acordo com os riscos reais de cada grupo e no momento da geração, assim como o acondicionamento como barreira de proteção, é o procedimento mais seguro de gerenciamento de risco contra contaminações e acidentes, sobrepondo-se aos requisitos para a destinação final. A exigência de tratar previamente os resíduos do subgrupo A4 antes de serem aterrados, conforme defendem alguns, poderia resultar em desnecessária elevação dos custos do processo sem evidência de redução dos riscos envolvidos.

RESUMO A energia sonora gerada nas cidades de todos os portes produz desconforto e, em algumas situações, doenças aos seus habitantes. Dessa forma, é necessário desenvolver ferramentas adequadas para a análise do ruído ambiental que deem suporte ao planejamento urbano. Os mapas acústicos, nesse contexto, podem auxiliar na organização dos espaços e de seus usos, podendo simular a futura paisagem sonora de uma região. O objetivo deste trabalho foi avaliar a contribuição dos mapas acústicos no planejamento urbano visando à melhoria da paisagem sonora das cidades. O local escolhido para o estudo foi a cidade de Campos do Jordão, estado de São Paulo, que pode ser considerada um exemplo de um lugar onde há a conurbação de atividades, gerando o conflito de interesses entre os cidadãos locais e turistas que procuram o descanso e os que procuram o entretenimento. Os mapas acústicos mostraram que a proximidade das áreas de entretenimento e residências eleva o nível de ruído, prejudicando a qualidade de vida naquela região.
Simulação de bombas com velocidade de rotação variável no EPANET
Authors: Coutinho Ricardo Santos , Soares Alexandre Kepler
Published: August 2017

RESUMO Em sistemas de distribuição de água, economia de energia elétrica pode ser alcançada pela substituição de bombas de rotação constante por bombas de rotação variável (BRV). Os elevados custos de instalação e operação de BRV requerem uma avaliação econômica prévia do projeto, a qual geralmente é acompanhada do uso de simuladores para análises hidráulicas do sistema. Um dos programas mais utilizados para esse fim é o EPANET 2, que é impreciso para computar a eficiência de BRV, pois o programa não leva em conta a mudança na curva de eficiência da bomba quando sua velocidade de rotação é alterada. Neste trabalho, uma rotina para o cálculo da eficiência de BRV, baseada em metodologia da literatura, foi implementada no código-fonte do EPANET 2. A influência da nova rotina nos resultados previstos pelo programa para eficiência, potência e consumo de energia de BRV foi avaliada em simulações com uma rede hipotética. Os resultados mostram que a versão original do EPANET 2 tende a subestimar a eficiência e, consequentemente, superestimar a potência e o consumo de energia de BRV. A versão modificada do EPANET 2 proporciona uma melhor previsão do comportamento de BRV e, portanto, o seu uso é recomendado na simulação de redes de distribuição de água equipadas com BRV.
“You Can't Run into a Burning Building without Getting Burned Yourself”: An Ecological Systems Perspective of Parents Choosing Out-of-Home Care for an Intercountry Adopted Child
Authors: Kim JaeRan
Published: August 2017

Increasingly, intercountry adopted children have special needs similar to children adopted from foster care in the United States. Out-of-home placement may be necessary when less restrictive services have not adequately addressed an adopted child's needs. The experiences of 19 adoptive parents who chose to place their intercountry adopted child in out-of-home care due to their child's disability were explored through qualitative interviews and family ecomaps. Themes emerging from interviews relate to adoptive parent definitions of adoption and disability, challenges identifying and accessing services, and the effects of placement on their family, within an ecological systems perspective. Findings show the need for service providers to better understand the impact of an intercountry adopted child's disability and preadoption history on family adjustment, as well as to support parents through the out-of-home placement process.
When Love is Not Enough: Parenting an Adopted Child with Mental Illness

Published: August 2017

This article presents the results of a qualitative study designed to explore the experiences of adoptive parents who placed an adopted child with mental illness in a residential treatment center (RTC). Twenty-four adoptive families from across the United States who placed an adopted child in residential treatment were interviewed. The adopted children represented various types of adoption including public child welfare, domestic infant, and intercountry adoption. Parents reported feeling victimized by their child and by the very systems designed to help them, including child welfare, mental health, health care, and education. The findings reveal signs of trauma in the adoptive parents as a result of their experiences. The article concludes with recommendations from adoptive parents for adoption, mental health, and residential treatment professionals who work with adopted children and their families.
Investigation and reconstruction of a London Underground tunnel, UK
Authors: Bowers Keith , Moss Neil
Published: August 2017

The central section of the London Underground Jubilee line was constructed in the 1970s. Various tunnel linings were used including a novel expanded lining where the tunnels passed through locally complex soils. Structural defects became apparent some two decades later and, by 2012, it was clear a 200 m section needed reconstruction. This was complicated by the need to maintain a high-intensity passenger train service through the tunnel if possible. This paper describes the bespoke demolition and relining system that was developed, tested and deployed to renew the structure incrementally in short, overnight maintenance periods while allowing traffic during the day.

New trends and technological advances in the treatment of these wounds demand attention regarding the care that must be afforded to patients to improve their quality of life. The most prevalent chronic wounds are pressure wounds and those related to gangrene. Objective: To identify the treatments for chronic wounds achieved by nursing personnel in the internal medicine services of a hospital in the city of Barranquilla. Materials and methods: A descriptive cross-sectional study of 51 nurses in the internal medicine services of a hospital in the city of Barranquilla. A test of injury treatments was used as an instrument of measurement and the data received was analyzed through the SPSS 20 statistical package. Results: 100% of the nurses used traditional treatments and the most common chronic injury was diabetic foot, at 73%. Conclusion: It was identified that the predominant chronic injury in the in the internal medicine services of the hospital in Barranquilla was diabetic foot, and the type of treatments that the nursing staff used was traditional, due to the fact that in that institution they do not access to the necessary resources to carry out the treatments with high technology. Nevertheless, the staff is aware that treatment with technology is efficient.
