The concept of "Development" has changed during the time. Recently it acquired a new social, politics, economic and cultural dimension, including issues such as human rights, liberty, democracy, cultural diversity, etc.. The alternative development model proposed by some authors stresses the concept of empowerment, which indeed alerts us to the crucial nature of those dimensions. Though considering the different cooperation for development actors, we shall focus here on the intervention of the Catholic Church. In fact, the areas where the Catholic Church intervenes or shows the potential to intervene upon are multiple. This diversity of influence is based on the capacity of the Catholic Church to integrate the very core of the local communities, bringing not only the resources, but the needed mechanisms to the effort of creating awaren...
O presente ensaio tem por objectivo abordar, de forma sintética, a problemática actualmente existente sobre o conceito de capital social, analisando, tanto as diferentes abordagens de que tem sido alvo, como as diferentes formas de medição, como, ainda, as perspectivas que são delineadas para o seu desenvolvimento futuro. Assim, partindo da abordagem do conceito avançada por Pierre Bourdieu (1986) no seu artigo "77?e Forms of Capita/, passando, depois para a abordagem de James Coleman (1988) em "Social Capita/ in the Creation of Human Capttar, seguindo para uma síntese das duas abordagens anteriores realizada por Philippe Steiner (1999) em La Sociooogie Economique. De seguida, debruçamo-nos sobre a perspectiva teórica de Robert Putnam (1996) a partir de The Strange Disappearance of Civic America, perspectiva que terá como um dos crític...
Background. Polyploidization is a major evolutionary process in plants where hybridization and chromosome doubling induce
enormous genomic stress and can generate genetic and epigenetic modifications. However, proper evaluation of DNA
sequence restructuring events and the precise characterization of sequences involved are still sparse. Methodology/Principal
Findings. Inter Retrotransposons Amplified Polymorphism (IRAP), Retrotransposons Microsatellite Amplified Polymorphism
(REMAP) and Inter Simple Sequence Repeat (ISSR) largely confirmed the absence of any intraspecific variation in wheat, rye
and triticale. The comparative analysis of banding profiles between wheat and rye inbred lines revealed 34% of monomorphic
(common to both parental species) bands for the ten different primer combinations used. The analysis of triticale pl...
The presented Model of Irrigation Management
was designed for application on
green spaces and leisure areas.
The Model recognizes water as a production
key-factor and optimizes its use on the
irrigation of green spaces, giving particular
attention to the temporal and spatial variation
of input variables.
Variables entered in the Model included
existing or future target plant species,
phenological phases, type of soil (i.e. location
and physical characteristics), topography
and climate factors.
Model construction was similar to the
methods outlined in FAO Report 56,
namely: the method of Penman-Monteith
for the calculation of reference evapotranspiration,
the use of dual cultural coefficients
to obtain cultural evapotranspirationand the opportunity of irrigation according
to the hydric balance.
The Model integrates t...
ABSTRACT:
A survey on seroprevalence of Q fever agent, Coxiella burnetii, in sheep flocks in the
Montemor-o-Novo district was performed in order to: i) estimate the prevalence of positive
flocks; ii)the animal prevalence within the flock.
Thirty-five flocks were randomly selected, comprising a total of 726 sheep. Blood samples
were collected to be tested by an ELISA commercial kit for the detection of phase I and
phase II anti-C. burnetii antibodies. Twenty flocks (57.1%) were identified with at least one
positive animal. The prevalence within the flocks ranged between 3% and 50%.
The epidemiological surveys and the investigation of outbreaks that occurred in the last years in several European countries show that Q fever must be considered an increasing public health concem, being the ruminants identified as the main source of ...

Dissertação Inaugural
The main objective of this work was the development of a new product, a Rocha pear
pulp nutritionally and sensory stabilized. The produced pulp also contains blackberry,
lemon/pineapple and wheat bran. It’s possible to produce an antioxidant and fibre enriched
food from an important pear variety, very characteristic from portuguese Oeste region. This
type of product is very instable and this is revealed by its colour. To prevent this situation the
study was based on chemical stabilization which was achieved by using two additives:
ascorbic acid and citric acid. The work was developed in several phases. Firstly it was
studied the effect of the additive application on pulp darkening followed by the establishment
of formulation limits in what concerns to additives concentration. Then pulps were produced
in accordance with the tem...
