Attitudes of College Students towards Agriculture, Food and the Role of Government
In 2002 and 2007 we surveyed Agribusiness students’ attitudes about agriculture, farming, food and agricultural policies. Responses were analyzed by year and student characteristics including farm background, citizenship and gender. Citizenship was a significant variable explaining differences in agreement with statements. Year and interactions with year were not significant.agricultural policy, farming, logistic regression, student attitudes, Agricultural and Food Policy, Teaching/Communication/Extension/Profession, A13, A22, C42, Q18,

Inverse Ising inference using all the data
We show that a method based on logistic regression, using all the data,
solves the inverse Ising problem far better than mean-field calculations
relying only on sample pairwise correlation functions, while still
computationally feasible for hundreds of nodes. The largest improvement in
reconstruction occurs for strong interactions. Using two examples, a diluted
Sherrington-Kirkpatrick model and a two-dimensional lattice, we also show that
interaction topologies can be recovered from few samples with good accuracy and
that the use of -regularization is beneficial in this process, pushing
inference abilities further into low-temperature regimes.Comment: 5 pages, 2 figures. Accepted versio
A Comparison of Phycocyanins from Three Different Species of Cyanobacteria Employing Resonance-Enhanced Coherent Anti-Stokes Raman Spectroscopy
Resonance-enhanced coherent anti-Stokes Raman spectra are recorded for monomers and trimers of phycocyanin from three different cyanobacteria: Westiellopsis prolifica, Mastigocladus laminosus and Spirulina platensis. It is shown that upon aggregation from monomer to trimer the electronic structures of both the α84 and β84 chromophores are changed. The spectra of the trimers originating from S. platensis and M. laminosus are very similar to each other, but distinctly different from the spectrum of W. prolifica
Co‐existing monophasic teratoma and uterine adenocarcinoma in a female dog
Ovarian teratomas are occasionally reported in dogs; the rarest type is the monophasic teratoma,composed of tissues originating from only one germ layer. Canine endometrial adenocarcinomas are also rare in dogs and mainly affect geriatric females.
This report describes case of co-existing ovarian teratoma and uterine adenocarcinoma in a 10-year old nulliparous female Boxer presented with lethargy, anorexia and purulent vaginal discharge.
Abdominal ultrasonography evidenced pyometra and a mass in the left ovary. This was composed of
a uniform whitish tissue with multiple cystic structures. The histology revealed an atrophy of the ovarian parenchyma, compressed by a proliferation of well-differentiated nervous tissue staining positively to vimentin, S100 and neuronal specific enolase (NSE), and negatively to keratin and inhibin. The left uterine horn, whose diameter was markedly increased, showed foci of endometrial cellular atypia, evident nucleoli and mitoses, at light microscopy.
To our best knowledge, this is the first report of a coexisting ovarian monophasic teratoma and
endometrial adenocarcinoma, two rare reproductive neoplasia in dogs
Nicorandil preserves the function of the mitochondrial phosphorylative and oxidative system in an animal model of global ischemia-reperfusion
Ischemia followed by reperfusion (IR) negatively affects mitochondrial function. At the level of the oxidative-phosphorylative system, IR inhibits the respiratory complexes and ATP synthase, and increases the passive leak of protons through the inner mitochondrial membrane, uncoupling respiration from phosphorylation, decreasing mitochondrial potential and, consequently, ATP production. Drugs that minimize the mitochondrial damage induced by IR may prove to be clinically effective. In the present work, we analyzed the impact of nicorandil, a mitochondrial ATP-sensitive potassium channel agonist, on mitochondrial dysfunction at the level of the oxidative-phosphorylative system of rat hearts subjected to IR. The decrease in the respiratory control ratio (RCR) induced by IR leads to the conclusion that IR has a negative impact on the activity of the mitochondrial respiratory system, uncoupling oxidation from phosphorylation. This effect is reversed by nicorandil, which increases not only RCR, but also the ADP/O ratio. Regarding respiratory rate, state 3 rate was approximately the same for all the experimental groups, while state 4 rate was lower for the group where IR was induced in the presence of nicorandil. This result is in accordance with the data obtained for the RCR and ADP/O. State 4 rate is most affected by uncoupling, given that it is controlled by proton leak. Mitochondria subjected to IR in the presence of nicorandil have a lower state 4 rate, i.e. they are less uncoupled. From these results we conclude that nicorandil preserves the function of mitochondria subjected to IR in terms of both respiration and phosphorylative capacity
Immunohistochemical Evaluation of TNF Expression in Canine Cystic Endometrial Hyperplasia
Tumour Necrosis Factor (TNF) has been identified in the
uterus of several species, and altered TNF expression is reported in some
pathological conditions. This study sought to evaluate TNF expression in
canine cystic endometrial hyperplasia (CEH; n=20) and compare it with
expression in postpartum samples (PP; n=5).This work was supported by Portuguese Foundation for Science and Technology, Center for Studies in Education, Technologies and by Health and by strategic project PEst-OE/CED/UI4016/201
THE IMPACT OF VOLUNTEERING AND THE ACQUISITION OF SKILLS THROUGH PRACTICE
This study intended to assess the impact of volunteering on society and understand how its practice
allows the acquisition of skills. In addition, it would make the population aware of the value and
importance of the different ways of volunteering. One of the central points of this investigation was to
understand how institutions should recruit and attract volunteers and ultimately how to retain them, by
understanding whether or not the volunteers’ initial motivations (i.e. which attract them) remain
unchanged along time. This study was carried out within the scope of the ENtRANCE Erasmus+
project, by students of the Research Methods and Techniques course integrated in the
Communication Sciences degree at Maia University Institute and had the collaboration of the
Volunteer School, Pista Mágica by contacting its volunteers and clarifying relevant information.
Several scientific articles were analysed, such as [1]; [2]; [3]; [4]; [5] which allowed a first approach to
such topic but with no answers found.info:eu-repo/semantics/publishedVersio

PORTUGUESE ENGAGED RESEARCH AND LEARNING COMMUNITY
The current research was performed within the ENtRANCE Erasmus+ project in order to identify how
may Portuguese Higher Education Institutions (HEI) provide independent participatory research
support in response to concerns experienced by civil society, namely based on EU societal
challenges. Even though the Biosense project [1] assumed the creation of the first Science Shop in
Portugal, it was only active between 2011 and 2013 and there is still no formal evidence of any other
one. Nevertheless, several Portuguese HEIs already provide informal services on behalf of citizens
and local civil society.info:eu-repo/semantics/publishedVersio
