Competências pessoais e sociais e representações sobre a diabetes dos jovens adultos com diabetes tipo 1
A maioria dos jovens apresenta boas competências pessoais e sociais e bom suporte social. Média de
satisfação com a vida 6,6 ±1,7.
A maioria dos jovens (64 a 99,6%) manifestou concordar com as representações positivas sobre a
diabetes. Na análise fatorial encontraram-se 2 fatores, que explicam 49% da variância total: instrumentais
e recursos (34%), perspetivas de vida (15%).
Conclusões
Apesar das dificuldades inerentes a esta fase da vida, os jovens com diabetes tipo 1 têm boas
competências pessoais e sociais, bom suporte social e satisfação com a vida e manifestam concordar com
as representações positivas sobre a diabetes
A EDUCAÇÃO PARA A SAÚDE NOS JOVENS COM DIABETES TIPO 1
-As mudanças sociais, ocupacionais, familiares e emocionais na vida
dos jovens com diabetes tipo 1 podem afetar a adesão ao tratamento e a sua
qualidade de vida. Uma das ferramentas mais úteis, e que poderá constituir uma
importante mais-valia para ultrapassar estas dificuldades, é a educação para a saúde
providenciada pela equipa multidisciplinar que acompanha os jovens.O objetivo
deste artigo é avaliar os comportamentos, estilos de vida e suporte social dos
jovens com diabetes tipo 1 e avaliar a satisfação em relação às atividades de
educação que lhes são proporcionadas.Foram realizados estudos quantitativos com
91 adolescentes e 278 jovens adultos, um estudo qualitativo com41 adolescentes e
estudos de avaliação de satisfação dos jovens.
A média de "satisfação com a vida" nos adolescentes é 7,2 ± 1,7 e nos jovens
adultos é 6,6 ± 1,7 (escala 0-10).A maior parte dos jovens evidencia hábitos
alimentares saudáveis e adesão satisfatória à atividade física, insulinoterapia e
vigilância glicemica. Contudo,a média de HbA1c é superior ao recomendado.
Consideram ter bom suporte da equipa de saúde e referem os benefícios das
atividades com outros jovens.Podemos concluir que os participantes têm estilos de
vida satisfatórios, bom suporte social e satisfação com a vida, valorizam as
atividades com os pares e têm razoável adesão ao tratamento da diabetes, mas um
controlo metabólico inferior ao esperado. Recomenda-se a continuidade do
investimento da equipa de saúde na motivação dos jovens para melhor adesão ao
tratamento
A Adaptação Psicológica à Diabetes dos Jovens Adultos com Diabetes Tipo 1
Introduction: Quality of life of young adults can be affected by the social, occupational, familiar and emotional changes.
Aims: Evaluation of life satisfaction, social support, treatment adherence and psychological adaptation of young adults with type 1 diabetes.
Methods: Quantitative study with questionnaires Àlled by 278 young adults with type 1 diabetes (18-35 years).
Results: Participants consider having good social support. Satisfaction with life was 6.6 ±1.7 (scale 0-10). Most of youngsters show good dietary
intake, one third practice recommended physical activity. Adherence to insulin therapy and glucose monitoring is satisfactory. They present
8.7±1.6% as mean value for HbA1c. Factorial analysis relating psychological adjustment to diabetes scale allowed to Ànd 4 factors explaining 50%
of total variance: diabetes adaptation (29%), diabetes control (8%), diabetes management competences (7%) e attitudes relating to diabetes (6%).
Youngsters with better psychological adaptation to diabetes have better adherence to diabetes treatment relating to nutrition, insulin therapy and
glucose monitoring.
Conclusions: Young adults showed good social support and satisfaction with life, a reasonable global adherence to diabetes treatment, good psychological
adaptation to diabetes, however with a less optimal metabolic control of diabetes. Youngsters with better psychological adaptation to
diabetes present better adherence to diabetes treatment
Managing English language teaching resource centres in the Mozambican context.
Thesis (M.Ed.)-University of Natal, Durban, 2000.This report seeks ways to improve the management of the existing English Language
Teaching Resource Centres (ELT-R/C) in Mozambique. Suggestions are made so as to
define clearly the place of the ELT-R/C and their managers in the education system
organizational structure; introduce other activities in the ELT-R/C; enlarge the number
ofELT-R/C users and improve the communication system and consequently the
relationships between the ELT-R/C and other education stakeholders. The report also
suggests the optional number of staff for the ELT-R/C and what should be done for the
Provincial English Advisors (PEA) to run the ELT-R/C more effectively and efficiently
Small-size MEMS accelerometer encapsulated in vacuum using Sigma-Delta modulation
A vacuum encapsulated MEMS accelerometer using Sigma-Delta modulation is here presented. Three different modulation orders (second, third, and fourth) were implemented in a field-programable gate array (FPGA), enabling flexibility for tuning the loop parameters in real-time. Three devices were measured, and the results are in good agreement with simulations performed in Simulink. A noise figure of 123 μg/√Hz for a bandwidth of 400 Hz and a range of at least ±1 g was experimentally measured. A figure of merit considering device size and bandwidth is proposed, highlighting the relevance of the results for the current state of the art.FCT - Fundação para a Ciência e a Tecnologia (PDE/BDE/114563/2016

Optimization of seasonality and mother plant nutrition for vegetative propagation of Pinus pinaster Ait
Due to the high economic importance of Pinus pinaster Ait., there is considerable interest in developing, improving and extending the use of its families for mass clonal propagation and in breeding programmes. In the current study, we evaluated shoot growth, rooting ability and mini-cuttings production of P. pinaster in response to nitrogen fertilization and seasons. We compared eight half-sib families of P. pinaster from Asturias and Galicia (Northern Iberian Peninsula), searching for useful parameters and growing conditions to be included in a mass propagation program for clonal family forestry. We fertilized P. pinaster seedling mother plants kept in a greenhouse with three levels of nitrogen: high (HN), medium (MN) and low (LN) to evaluate rooting ability of mini-cuttings. In addition, we evaluated the maximal potential production of rooted mini-cuttings considering nine cycles of propagation over 1 year, also using three levels of nitrogen. The HN treatment significantly influenced the rooting process, with length, area and volume of roots all being positively affected. Spring was the most favourable season for mini-cuttings in the HN treatment. This study provides valuable new information to optimize the clonal propagation protocol for P. pinaster and shows that the mini-cuttings technique has great potential in mass scale cloning, providing high quality sprout production and well-formed new plants
Anti-Hepatocellular Carcinoma (HepG2) activities of Monoterpene Hydroxy Lactones isolated from the Marine Microalga Tisochrysis Lutea
Tisochrysis lutea is a marine haptophyte rich in omega-3 polyunsaturated fatty acids (e.g., docosahexaenoic acid (DHA)) and carotenoids (e.g., fucoxanthin). Because of the nutraceutical applications of these compounds, this microalga is being used in aquaculture to feed oyster and shrimp larvae. In our earlier report, T. lutea organic crude extracts exhibited in vitro cytotoxic activity against human hepatocarcinoma (HepG2) cells. However, so far, the compound(s) accountable for the observed bioactivity have not been identified. Therefore, the aim of this study was to isolate and identify the chemical component(s) responsible for the bioactivity observed. Bioassay-guided fractionation through a combination of silica-gel column chromatography, followed by preparative thin layer chromatography (PTLC), led to the isolation of two diastereomers of a monoterpenoid lactone, namely, loliolide (1) and epi-loliolide (2), isolated for the first time in this species. The structural elucidation of both compounds was carried out by GC-MS and 1D (1H and 13C APT) and 2D (COSY, HMBC, HSQC-ed, and NOESY) NMR analysis. Both compounds significantly reduced the viability of HepG2 cells and were considerably less toxic towards a non-tumoral murine stromal (S17) cell line, although epi-loliolide was found to be more active than loliolide.FCT, Portugal: UID/Multi/04326/2019, UID/MAR/04292/2020 (MARE), UID/Multi/04046/2020 (BioISI) and

Influence of mechanical stress in a packaged frequency-modulated MEMS accelerometer
Frequency modulated accelerometers composed of two double-ended tuning fork (DETF) resonators on a differential configuration were characterized for their sensitivity to force applied to their package. Commonly, differential architectures are employed to cancel common mode errors, such as the mechanical stress or temperature dependency. The device dependence to mechanical stress was experimentally measured for forces up to 15 N and a reduction of about 5.6 times was obtained on the differential measurement. Additionally, the silicon dies were glued to chip-carriers using two different glues with distinct properties, and their sensitivity to stress was compared. The effectiveness of a viscoelastic glue over an epoxy-based glue for stress decoupling was tested. Long-term measurements under constant force were experimentally performed and for a time period of approximately 100 min, the stress relaxation and creeping of the viscoelastic glue enabled the recovery to the initial output of the sensor.The first author is supported by FCT - Fundacao para a Ciencia e Tecnologia through the grant PDE/BDE/114564/2016.
