Desenvolvimento psicossocial e ansiedades nos jovens
Este estudo, baseado na perspectiva do desenvolvimento
psicossocial de Erikson, teve como principal
objectivo estudar a relação entre as diferentes tarefas
desenvolvimentais e a ansiedade nos jovens. Na presente
investigação foi utilizada uma amostra de 511
jovens portugueses, com idades compreendidas entre
os 17 e os 26 anos, que frequentavam diferentes cursos
universitĂĄrios em estabelecimentos de ensino superior
da ĂĄrea metropolitana do Porto.
De modo geral, verifica-se que a uma resolução das
tarefas psicossociais de forma construtiva corresponde
uma menor tendĂȘncia para a ansiedade.
Relativamente ao género, registam-se efeitos significativos
nos medos, pensamentos obsessivos e comportamentos
compulsivos e nos estĂĄdios do desenvolvimento
psicossocial. Verifica-se que o género feminino
assume médias mais elevadas na maior parte dos medos
e o gĂ©nero masculino nas caracterĂsticas obsessivo-
compulsivas. O efeito do género nas diferentes tarefas
psicossociais só se mostra significativo para a confiança
vs. desconfiança em que as raparigas apresentam
médias mais baixas comparativamente aos rapazes
e mĂ©dias mais elevadas na tarefa da indĂșstria vs. inferioridade.This research, based on the Eriksonâs psychosocial
development perspective, has as its fundamental goal
to study the relations between developmental psychosocial
tasks and anxiety in young people. In this study
we used a sample of 511 Portuguese young people, with
ages between 17 and 26 years, which attended several
higher education courses in the Porto area.
Globally, results show that a constructive resolution
of psychosocial tasks corresponds to a smaller tendency
for anxiety. Results also allow the understanding of
the specific contribution each stage has concerning the
development of different anxious structures.
As for gender, results indicate the presence of significant
effects for fears, obsessive thoughts and compulsive
behaviours, as well as for psychosocial developmental

Mixing efficiency on plant cell growth and proteinase production in a stirred tank reactor
Mixing efficiency is one of the most significant factors in bioprocess productivity.
The major role of agitation is to improve broth homogenization, mass and heat
transfer inside the bioreactors
Alpha-Hemoglobin-Stabilizing Protein: An Erythroid Molecular Chaperone
Alpha-hemoglobin-stabilizing protein (AHSP) is an erythroid-specific protein that acts as a molecular chaperone for the free α chains of hemoglobin. Evidence strongly suggests that AHSP participates in hemoglobin synthesis and may act to neutralize the cytotoxic effects of excess free alpha-globin subunits that accumulate both in normal and beta-thalassemic erythroid precursor cells. As such, AHSP seems to be essential for normal erythropoiesis, and impaired upregulation of AHSP may lead to premature erythroid cell death, resulting in ineffective erythropoiesis. Reduced AHSP mRNA expression has been associated with clinical variability in some cases of ÎČ-thalassemia. It has been shown that αHb variants may also impair AHSP-αHb interactions, leading to pathological conditions that resemble α-thalassemia syndromes. The aim of this paper is to summarize current information concerning the structure and function of AHSP, focusing on its role in normal erythropoiesis and its relevance in health and disease
The performance of an aerated stirred tank reactor on VHG batch fermentations
The quest for new and renewable energy sources has greatly increased due to
the depletion of fossil fuels reserves. Agro-food wastes appear as a cheap and
renewable energy source that can contain great amounts of carbon to be
transformed in bioethanol that can be used as additive to gasoline
Cinética do crescimento de células em suspensão de Cynara cardunculus em reactores biológicos
Tese de Doutoramento, Biotecnologia Vegetal, Unidade de CiĂȘncias e Tecnologias AgrĂĄrias, Universidade do Algarve, 1994A espĂ©cie vegetal Cynara cardunculus L., vulgarmente conhecida por cardo das hortas ou cardo do coalho, encontra-se disseminada por toda a bacia mediterrĂąnica, quer sob a forma espontĂąnea quer sob a forma cultivada. Para alĂ©m de diversas aplicaçÔes no campo terapĂȘutico, das suas folhas e raĂzes, Ă© reconhecida a elevada capacidade das flores para coagular o leite. Esta propriedade tem sido atribuĂda Ă presença de proteases na planta e tem possibilitado a utilização, no nosso paĂs, das flores secas desta planta, no fabrico
artesanal de queijo.The thistle Cynara cardunculus L. is wide spread in the mediterranean and is traditionally used in Portugal in farm house cheese-making, due to the milk clotting activity of the proteases. It has also been used, since early days, as medicine and has several curative properties

A web-based psychoeducational simulation game for adults in stepfamilies (GSteps)-study protocol for a randomized controlled feasibility trial
BACKGROUND: Stepfamilies are a prevalent family form. However, less stable than nuclear, first marriage families due to the presence of risk factors such as the absence of social norms and the presence of stepchildren. Stepfamilies have unique educational needs regarding stepparenting and co-parenting issues. The development and documentation of psychoeducational intervention strategies can facilitate dissemination of ongoing studies and promote transparency. This article describes the background, design and protocol of a randomized controlled trial (RCT) evaluating the eficacy and feasibility of a web-based Psychoeducational Simulation Game (GSteps). Behavior-modeling video training (BMT) is used to demonstrate and promote relational skills, stepparenting and co-parenting effective strategies for adults in stepfamilies. A mental health professional will be available within the GSteps platform for clarification or emotional support. METHODS/DESIGN: A RCT design is presented to evaluate the outcomes of a self-administered, interactive and web-based psychoeducational Game targeting dyadic marital adjustment and interpersonal skills as the primary outcomes and remarriage beliefs, family function and stepparenting and co-parenting attitudes as the secondary outcomes. Other outcome measures include satisfaction with GSteps, participantsâ knowledge learned after the intervention and a purposive sampling method will be used to access feasibility. The minimum required sample size is 112 participants (56 per condition) randomly allocated either to an experimental group (EG), receiving GSteps intervention, or to a wait-list control group (CG). A survey is conducted electronically. Assessments take place at baseline (T(0)), after the intervention (T(1)) and 1-month follow-up (T(2)). DISCUSSION: This protocol presents a RCT aimed at evaluating the efficacy of a web-based psychoeducational intervention (GSteps) designed for improving marital, stepparenting and co-parenting skills in adults who live in stepfamilies. The use of the protocol and results of intervention studies may guide the use and refinement of web-based psychoeducational intervention for stepfamilies. Additionally, GSteps may become a tool for health professionals to enhance stepfamily functioning, stepparenting skills, and marital adjustment of remarried adults
