description: Objetivos: A forma larvar de algumas espécies de ácaros trombiculídeos (Acari: Trombiculidae) parasitam mamíferos, sendo responsáveis principalmente pelo aparecimento de sinais clínicos dermatológicos. Apesar do seu potencial zoonótico, a caracterização da diversidade genética de ácaros trombiculídeos com importância médica é escassa. O objetivo deste trabalho foi fazer a caracterização molecular de ácaros trombiculídeos obtidos de um gato errante.


Materiais e métodos: Seis ácaros da família Trombiculidae foram recolhidos de um gato errante e preservados em álcool a 70%. Após a extração de DNA de cada exemplar utilizando um kit comercial, foi amplificado o gene codificante da citocromo C oxidase I (COI) por PCR convencional. Os produtos de reação foram purificados e sequenciados pelo método de Sanger. A diversidade genética foi analisada através de árvores filogenéticas inferidas pelo método de máxima verossimilhança.


Resultados: Quando comparadas com as sequências existentes no GenBank, via BLAST®, as sequências COI dos 6 ácaros em análise apresentaram elevada identidade com a sequência de referência de Neotrombicula vulgaris [KY888693]. Na árvore filogenética, as sequências obtidas formaram um cluster monofilético estável, juntamente com a sequência de referência de N. vulgaris. A análise sugere também a existência de diversidade intraespecífica.


Conclusões: Este estudo preliminar permitiu aumentar a representatividade de sequências genéticas da espécie de N. vulgaris contribuindo para uma mais fácil identificação, em trabalhos futuros, de exemplares capturados em animais e/ou no ser humano. Serão também necessários estudos para clarificar a importância clínica desta espécie em gatos e o seu potencial enquanto vetores de agentes infeciosos.

description: The role of microcredit program to alleviate poverty and empower women in developing countries is still in debate. This study attempts to evaluate the impact of such programs by measuring borrowers’ social mobility. Using a multidimensional approach, indicators like household income, economic susceptibility, living conditions, consumption pattern, children’s education, healthcare facilities, women’s participation in decision-making have been taken into account for measurement. Quantitative method has been used. Based on a non-probability sampling, 107 microcredit borrowers have been selected for interviewing who live in a rural, a semi-urban and an urban area. Statistical analysis of the data reveals that those who have been taking loans for several number of years have all managed to increase their income level to a variety of extent, but only those have gained some sort of mobility who have been taking loans for more than 4-5 years and have taken 5 times or more. Positive responses about the indicators being used in the study are found among the handful of those who have mobilized significantly. In true sense, most of the borrowers are stuck at the bottom end of socio-economic ladder and are struggling to manage a better living standard

Iberian hare and European rabbit extinctions: the foundation of a Breeding Centre in Portugal
Creators: name: Abade Dos Santos, Fábio
Publisher: name: Revista Lusófona de Ciência e Medicina Veterinária
Year: 2024

description: Introduction: The Iberian hare (Lepus granatensis) and wild rabbit (Oryctolagus cuniculus algirus) are endemic and key species, that have declined the hare by more than 50% in the last four years after the emergence of a natural recombinant myxoma virus (ha-MYXV) and the putative reactivation of Leporid gammaherpesvirus 5 (LeHV-5) which together will lead to the reclassification of its conservation status to Vulnerable by the IUCN this year.


Material & Methods: Physical and technical facilities (about 2 ha) were created including breeding, feeding and physical training parks as well as methods for disinfection, deworming, and capture of animals with minimal stress, and the specific probe was built for the Iberian hare for semen collection.


Results: Currently, the centre has 4 epidemiological units with 60 hares and 2 epidemiological units with 40 wild rabbits (Endangered, IUCN). During this year, repopulations were started (43 hares and 67 rabbits) in Évora with 2.7% of mortality.The eletrojeaculaton method has allowed the collection of sperm in about 5-10 minutes, of a concentration of 1.06x109±7.98x108 spz/mL.


Discussion:  In the next years the annual restocking will include 200 hares and 300 rabbits. Artificial insemination will be started and it is expected that improve the species' prolificacy, increasing the number of animals released into the wild.

description: The Nilsson orbitals used in the substitutions occurring in the proxy-SU(3) scheme, which are the orbitals bearing the maximum value of total angular momentum in each shell, have an extremely simple structure in the shell model basis |N l j Omega>, with each Nilsson orbital corresponding to a single shell model eigenvector. This simple structure is valid at all deformations for these orbitals, while in other orbitals it is valid only at small deformations. Nilsson 0[110] pairs are found to correspond to |1 1 1 0> pairs in the spherical shell model basis, paving the way for using the proxy-SU(3) approximation within the shell model.

description: Understanding the structural underpinnings of magnetism is of great fundamental and practical interest. Se_{1-x}Te_{x}CuO_{3} alloys are model systems for the study of this question, as composition-induced structural changes control their magnetic interactions. Our work reveals that this structural tuning is associated with the position of the supposedly dummy atoms Se and Te relative to the super-exchange (SE) Cu--O--Cu paths, and not with the SE angles as previously thought. We use density functional theory, tight-binding, and exact diagonalization methods to unveil the cause of this surprising effect and hint at new ways of engineering magnetic interactions in solids.

description: Canine herpesvirus type I (CHV-1), widely spread among dogs in breeding kennels, is thought to be a major cause of infertility, reproductive disorders and neonatal mortality. In adults, infection remains latent and can be reactivated during stressful events. However, the correlation between the shedding of the virus and the phase of the estrous cycle is still unknown.


Objectives: The present study aimed to identify the presence of CHV-1 in bitches and to correlate its presence with the different phases of the estrous cycle, the bitches' reproductive health, epidemiological parameters and management conditions.


Material & Methods: Between September 2021 and April 2022, 60 bitches of various ages and breeds, attending reproduction consultation at Anicura Atlântico Veterinary Reproduction Centre, were included in the study. For each animal, a vaginal swab was collected and a questionnaire about the bitches’ health and reproductive history was filled. For each animal, the phase of the estrous cycle was determined, DNA was extracted from vaginal swabs and real-time PCR was performed to detect the presence of CHV-1 DNA.


Results: CHV-1 DNA was detected in 3,3% (2/60) of the samples. Both were adult animals in estrus, without CHV-1 vaccination, belonging to breeding kennels with history of infertility.


Conclusions: As far as the authors are aware, the present study constitutes the first description of CHV-1 molecular detection in female dogs in Portugal. The fact that the virus was identified during estrus, highlights the need for further studies to clarify an eventual association of the follicular phase and virus reactivation, which may impair ulterior fertility. Also, lack of vaccination against CHV-1 during pregnancy, kennel dimensions and animals’ density may predispose to a higher frequency of (re)infection. Further studies are needed for a better understanding of CHV-1 transmission and the association of the infection with the reproductive health of female dogs.

description: The aim of the survey was the assessment of changes affecting entrepreneurship in rural areas of Lower Silesian Province in the years 2002-2011, in spatial terms. The assessment was based on index of enterpreneurial activity, referring to the number of business entities registered in REGON system, caunted over one thousand inhabitants. The research covered 133 rural communities and urban – rural communities. The analysis of spatial distribution of Lower Silesian communities, representing diverse levels of entrepreneurship, made use of statistical method of cluster analysis. In the examined period, diversification of rural areas regarding their state of entrepreneurship took place. Economic activity featured especially the communities surrounding Wrocław urban agglomeration, Legnica and Głogów urban agglomeration, as well as the communities in The Sudetes region.

description: The purpose of this article is to determine the present as well as the desired by entrepreneurs in the future activity of local government units in the creation of conditions conducive to the development of catering points and gastronomic establishments and accommodation facilities operating in the province of Lublin. In economic practice the entrepreneurs scarcely use the assistance offered by local governments. Despite this, they critically evaluate local governments’ actions, especially commune offices associated with the use of exemptions and tax reliefs. In the opinion of the respondents, they are used very rarely, and if they are, it is insufficient. In the future, the owners of the catering and accommodation enterprises functioning in the province of Lublin expect to the greatest extent the reduction of the fiscal burden and simplifying the formal procedures in the course of business activity.

description: Planck scale physics represents a future challenge, located between particle physics and general relativity. The Planck scale marks a threshold beyond which the old description of spacetime breaks down and conceptually new phenomena must appear. Little is known about the fundamental theory valid at Planckian energies, except that it necessarily seems to imply the occurrence of a minimal length scale, providing a natural ultraviolet cutoff and a limit to the possible resolution of spacetime. Motivated by String Theory, the models of large extra dimensions lower the Planck scale to values soon accessible. These models predict a vast number of quantum gravity effects at the lowered Planck scale, among them the production of TeV-mass black holes and gravitons. Within the extra dimensional scenario, also the minimal length comes into the reach of experiment and sets a fundamental limit to short distance physics. We review the status of Planck scale physics in these effective models.

description: We study the problem of selecting control clones in DNA array hybridization experiments. The problem arises in the OFRG method for analyzing microbial communities. The OFRG method performs classification of rRNA gene clones using binary fingerprints created from a series of hybridization experiments, where each experiment consists of hybridizing a collection of arrayed clones with a single oligonucleotide probe. This experiment produces analog signals, one for each clone, which then need to be classified, that is, converted into binary values 1 and 0 that represent hybridization and non-hybridization events. In addition to the sample rRNA gene clones, the array contains a number of control clones needed to calibrate the classification procedure of the hybridization signals. These control clones must be selected with care to optimize the classification process. We formulate this as a combinatorial optimization problem called Balanced Covering. We prove that the problem is NP-hard, and we show some results on hardness of approximation. We propose approximation algorithms based on randomized rounding and we show that, with high probability, our algorithms approximate well the optimum solution. The experimental results confirm that the algorithms find high quality control clones. The algorithms have been implemented and are publicly available as part of the software package called CloneTools.

description: Un des principaux objectifs des différentes réformes successives de la PAC est de soumettre davantage l’offre agricole européenne aux signaux des marchés. De fait, la recherche de compétitivité devient une préoccupation majeure des agriculteurs. Les moins performants doivent rattraper les plus efficaces en essayant d’adopter progressivement les meilleures pratiques. Notre étude tente de révéler et de mesurer ces éventuels phénomènes de convergence des performances productives entre les exploitations agricoles. Elle porte sur 178 exploitations spécialisées en grandes cultures et situées dans un même bassin de production (Nord-Pas-de-Calais), au cours de la période 1994-2001 (période d’application de la réforme Mac Sharry et des premières mesures d’Agenda 2000).À partir d’estimations des niveaux de la productivité globale des facteurs basées sur la notion de fonction de distance, nos résultats indiquent clairement des processus de rattrapage, à la fois technique, et d’échelle entre les exploitations

We analyze the motion of single electrons on and off the nanoparticle through the tunneling current, the displacement current and the charging-induced electrostatic force on the vibrating nanoprobe. We demonstrate the mechanical single-electron turnstile effect by applying the theory to a gold nanoparticle connected to the gold substrate through alkane dithiol molecular bridge and probed by a vibrating platinum tip.

description: Several proposed techniques for distinguishing between optical coherent states are analyzed under a physically realistic model of photodetection. Quantum error probabilities are derived for the Kennedy receiver, the Dolinar receiver and the unitary rotation scheme proposed by Sasaki and Hirota for sub-unity detector efficiency. Monte carlo simulations are performed to assess the effects of detector dark counts, dead time, signal processing bandwidth and phase noise in the communication channel. The feedback strategy employed by the Dolinar receiver is found to achieve the Helstrom bound for sub-unity detection efficiency and to provide robustness to these other detector imperfections making it more attractive for laboratory implementation than previously believed.

description: A termesztett növények, növényi részek akkumulációs képessége, toxikus elem tartalma eltérő. A termés mennyiségét megszorozva a benne található elemek koncentrációjával megkapjuk a felvett mennyiségeket. Ezzel adatokhoz juthatunk a terület mikroelem/szennyezőelem mérlegének számításához, a táplálék- lánc terheltségének megítéléséhez, ill. a termesztendő növények megválasztásához, a vetési sorrend összeállításához. Környezetvédelmi szempontból különösen veszélyes elemek (Cd, Cr, Hg, Pb) nagyobb mennyisége a vegetatív szártermésbe épül be. Az As és a Hg nem jut be a szemtermésbe, így a Hg-nyal és az As-nal terhelt talajokat gabonafélékkel hasznosítjuk (búza, szemes kukorica). A szennyezett területeken termesztett kukorica silóként történő hasznosítását nem javasoljuk, a toxikus elemek főleg a leveles szárban akkumulálódnak. A szármaradványok talajba dolgozásával csökkenthető a veszélyes mikroelemek kikerülése az agronómiai körforgalomból. A teljes föld feletti termésbe beépült elemek kis mennyisége miatt az őszi búza, kukorica és napraforgó fitoremediációs talajtisztítási eljárásokban nem alkalmazhatók eredményesen. ------------------ Cultivated plants and their parts differ in respect of their accumulating capacity and toxic element content. Yield multiplied by the concentration of elements in it equals the amounts taken up. This way, data can be obtained for counting the balance of micro-elements/contaminating elements on a given area, estimating the burden weighing on food chain, and electing plants to be cultivated & compiling their sowing order. Greater quantities of elements especially dangerous in respect of environmental protection (Cd, Cr, Hg, Pb) assimilate in the stems. As and Hg do not get into grain, wherefore soils contaminated by Hg and As can be utilised by means of cropping cereals (wheat, grain maize). However, it is not recommended to utilise maize cultivated on contaminated areas as silage because toxic elements accumulate mainly in leaved stems. The ploughing of stem residues in the soil enables dangerous micro-elements to be eliminated from agronomic circulation. Owing to the small amount of elements assimilated in the entire above-ground yield winter wheat, maize, and sunflower cannot be successfully used in phyto- remedial soil cleaning techniques.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

In the name of democracy : the work of women teachers in Toronto and Vancouver, 1945-1960

Publisher: name: University of British Columbia

description: In the Name of Democracy: The Work of Women Teachers in Toronto and Vancouver, 1945-1960, examines the limits of educational ’democracy’ for women educators. Educational administrators across the political spectrum assumed separate spheres to be intrinsic to the social contract for ’good’ citizenship: the school as a public institution was dedicated to the rational, autonomous, politically engaged subject. ’Woman’ was not that subject. This thesis demonstrates that women were quasi-citizens in the public school, yet leaders in the delivery of democratic hope for the age. On the one hand, women teachers were encouraged to participate in the increasingly ’democratized’ institution of the public secondary school and were embraced as necessary participants in the labour market of the education system. In the years after the Second Great War, the reconstitution of the social order depended upon their performance. On the other hand, the maintenance of traditional gender roles, disrupted by the trauma of war, was still heralded as women’s primary contribution to the nation’s stability. While women teachers acted within public institutions, their role remained defined by their private sphere ’capabilities’ and a gendered model of citizenship that promised security through the performance of educational ’democracy.’ This thesis employs a feminist analysis that centers on women teachers’ oral histories to illuminate both the normative democratic order of the period and the ways that women negotiated its boundaries. In particular, it combines modernist concerns for social structure and common oppression with poststructuralism’s concern for hierarchies of identification and difference. Both the common and discrete experiences of women teachers reveal that educational ’democracy’ was far from gender-blind in post-war Canada.

description: The agricultural sector is often considered as the biggest water consumer and is as such more and more targeted by policies aimed at saving water, in view of the global warming. Farmers are adaptating to this societal requirement by embracing less consuming irrigation techniques. In an interesting multidisciplinary approach, we intend to demonstrate how the territorial network of gravity irrigation canals in Provence play a role when it comes to dealing with the water management and sharing in the long run. Given this, traditional irrigation canals need to be reexamined for their usefulness in the context of global warming and the issues of water scarcity or excess raised thereby in the Mediterranean region. They are not only built aquatic infrastructure with a very positive, still little recognized, environmental impact; they are also the product of a culture and social relationship with water in this part of the world.

description: A doença do trato respiratório superior (URTD) é uma causa frequente de morbilidade e mortalidade em tartarugas selvagens e em cativeiro. Mycoplasma agassizii é um importante agente causador da URTD. A infeção por este agente pode apresentar-se nas formas crónica ou subclínica, com recidivas sintomáticas intermitentes. Os animais assintomáticos podem atuar como portadores de Mycoplasma agassizii. A crescente procura de tartarugas terrestres como animais de estimação, associada elevada taxa de transmissão deste agente, constituem fatores de ameaça à sobrevivência destas espécies.


Objectivos: O objetivo deste estudo foi o de estimar, por diagnóstico molecular, a frequência da infeção por Mycoplasma agassizii em tartarugas terrestres saudáveis sob cuidados humanos.


Material e Métodos: Foram incluídos no estudo 55 tartarugas terrestres sem evidência de sinais clínicos, às quais foram recolhidas zaragatoas orais. Após a extracção de DNA, foi feita a deteção de Mycoplasma agassizii através de PCR convencional. Todos os animais em estudo pertenciam à família Testudinidae e às seguintes espécies: Aldabrachelys gigantea (n=1), Astrochelys radiata (n=2), Centrochelys sulcata (n=9), Chelonoidis carbonarius (n=8), Indotestudo elongata (n=2), Malacochersus tornieri (n=3), Stigmochelys pardalis (n=7), Testudo graeca (n=13), Testudo hermanni (n=4), Testudo horsfieldii (n=4) e Testudo marginata (n=2). Os animais pertenciam a um total de 7 coleções distintas, dividindo-se por 18 populações, de várias regiões de Portugal Continental.


Resultados: Todas as coleções foram positivas para Mycoplasma agassizii. O estudo revelou uma presença preocupante deste agente em 69,1% (38/55) das amostras, com apenas três populações totalmente livres da infeção.


Conclusões: O facto de ter sido identificada, em animais saudáveis, uma frequência de infeção de 69,1% é preocupante devido ao papel que estes animais podem ter na disseminação do agente. O crescente comércio destas espécies constitui um risco de transmissão do agente a outras regiões geográficas. Este trabalho representa um importante contributo para uma melhor compreensão do impacto epidemiológico e clínico da infeção por Mycoplasma agassizii na fauna cativa de tartarugas no nosso País.

description: This article starts from the observation that organic farms survive and expand, despite the difficulties they face. We analyze these processes by means of organization theories and in particular the Resource Dependence Theory (RDT). We interviewed some thirty organic farmers twice in an interval of ten years in order to identify how they depend on their environments (economic, legal, etc.) and which strategies they implement to have control on them. These strategies are highly diverse, from one farm to another, they are also very unstable and they are characterized by multiple links between them. This analysis of the strategies of organic farmers completes usefully the empirical researches on organic farming; it also questions the assumptions of the RTD, to which we confer a more systemic dimension.

The elements of social disqualification include social fragility (how they are perceived by the majority of conventional producers) and economic dependency on integrators who provide the selected animals, food and even therapeutics in some cases. While subcontracting breeding is largely regarded as a more economical means to produce livestock or poultry, this study hypothesized the subcontractors are socially disqualified on the grounds of having minimal professional autonomy or knowledge on the actual breeding or management of livestock. Comprehensive interviews were conducted with subcontracting breeders of calf, pig and poultry. We show that social disqualification of subcontractors is based on their feeling of over-dependence on the farm integrator and the integrators lack of recognition for their quality of work.

description: The single-particle spectral function of a strongly correlated system is an essential ingredient to describe its dynamics and transport properties. We develop a general method to calculate the exact spectral function of a strongly interacting one-dimensional Bose gas in the Tonks-Girardeau regime, valid for any type of confining potential, and apply it to bosons on a lattice to obtain the full spectral function, at all energy and momentum scales. We find that it displays three main singularity lines. The first two can be identified as the analogs of Lieb-I and Lieb-II modes of a uniform fluid; the third one, instead, is specifically due to the presence of the lattice. We show that the spectral function displays a power-law behaviour close to the Lieb-I and Lieb-II singularities, as predicted by the non-linear Luttinger liquid description, and obtain the exact exponents. In particular, the Lieb-II mode shows a divergence in the spectral function, differently from what happens in the dynamical structure factor, thus providing a route to probe it in experiments with ultracold atoms.

description: We study the connection of the dynamics in relativistic field theories in a strong magnetic field with the dynamics of noncommutative field theories (NCFT). As an example, the Nambu-Jona-Lasinio models in spatial dimensions $d \geq 2$ are considered. We show that this connection is rather sophisticated. In fact, the corresponding NCFT are different from the conventional ones considered in the literature. In particular, the UV/IR mixing is absent in these theories. The reason of that is an inner structure (i.e., dynamical form-factors) of neutral composites which plays an important role in providing consistency of the NCFT. An especially interesting case is that for a magnetic field configuration with the maximal number of independent nonzero tensor components. In that case, we show that the NCFT are finite for even $d$ and their dynamics is quasi-(1+1)-dimensional for odd $d$. For even $d$, the NCFT describe a confinement dynamics of charged particles. The difference between the dynamics in strong magnetic backgrounds in field theories and that in string theories is briefly discussed.

description: An increasing number of studies suggest that compensation fees for participating in valuation studies can influence participant’s responses. This study investigates the impact that compensation has on individuals’ responses in a point -of-purchase setting, when the opportunity costs of participation are relatively small and participants are familiar with the products. We conducted a field experiment using the incentive compatible Becker-DegrootMarschak (BDM) mechanism to elicit consumers’ willingness-to-pay values for organically produced apples. Our results suggest that despite receiving similar information, compensated individuals tended to offer willingness-to-pay values that were significantly larger on average than those values offered by non- compensated individuals

Intense terahertz laser fields on a two-dimensional electron gas with Rashba spin-orbit coupling

description: The spin-dependent density of states and the density of spin polarization of an InAs-based two-dimensional electron gas with the Rashba spin-orbit coupling under an intense terahertz laser field are investigated by utilizing the Floquet states to solve the time-dependent Schrödinger equation. It is found that both densities are strongly affected by the terahertz laser field. Especially a terahertz magnetic moment perpendicular to the external terahertz laser field in the electron gas is induced. This effect can be used to convert terahertz electric signals into terahertz magnetic ones efficiently.

description: We show that a stochastic approach enables calculations of the optical properties of large 2-dimensional and nanotubular excitonic molecular aggregates. Previous studies of such systems relied on numerically diagonalizing the dense and disordered Frenkel Hamiltonian, which scales approximately as $\mathcal{O}(N^3)$ for $N$ dye molecules. Our approach scales much more efficiently as $\mathcal{O}(N\log(N))$, enabling quick study of systems with a million of coupled molecules on the micron size scale. We calculate several important experimental observable including the optical absorption spectrum and density of states, and develop a stochastic formalism for the participation ratio. Quantitative agreement with traditional matrix diagonalization methods is demonstrated for both small- and intermediate-size systems. The stochastic methodology enables the study of the effects of spatial-correlation in site energies on the optical signatures of large 2D aggregates. Our results demonstrate that stochastic methods present a path forward for screening structural parameters and validating experiments and theoretical predictions in large excitonic aggregates.

description: The role of microcredit program to alleviate poverty and empower women in developing countries is still in debate. This study attempts to evaluate the impact of such programs by measuring borrowers’ social mobility. Using a multidimensional approach, indicators like household income, economic susceptibility, living conditions, consumption pattern, children’s education, healthcare facilities, women’s participation in decision-making have been taken into account for measurement. Quantitative method has been used. Based on a non-probability sampling, 107 microcredit borrowers have been selected for interviewing who live in a rural, a semi-urban and an urban area. Statistical analysis of the data reveals that those who have been taking loans for several number of years have all managed to increase their income level to a variety of extent, but only those have gained some sort of mobility who have been taking loans for more than 4-5 years and have taken 5 times or more. Positive responses about the indicators being used in the study are found among the handful of those who have mobilized significantly. In true sense, most of the borrowers are stuck at the bottom end of socio-economic ladder and are struggling to manage a better living standard

description: Objetivo: O objetivo deste estudo retrospetivo foi obter informações sobre a ocorrência de B. canis, em cães, em Portugal.


Materiais e métodos: Foi selecionada uma coleção de amostras de soro recebidas entre o período compreendido de 2014 e 2022 no Laboratório Nacional de Referência em Saúde Animal, do Instituto Nacional de Investigação Agrária e Veterinária (INIAV). A coleção incluiu 642 amostras soro e 252 amostras de tecidos/sangue para extração de DNA, de diferentes regiões de Portugal, incluindo Açores e Madeira.


Todos os soros foram testados pelo teste de fixação de Complemento (baseado no antígeno de B. ovis, CFT-B. ovis); a partir destes, 438 amostras também forma testadas pelo Teste Rápido de Aglutinação em lâmina (RSTA e ME-RSTAT) e/ou teste clínicos (incluindo amostras de sangue, esfregaços vaginais, feto abortado) foram submetidas para deteção de Brucella spp.


Resultados: A frequência de resultados serológicos positivos foi de 9,7% (62 em 642 cães) usando CFT-B. ovis, mas 7.3% das amostras testadas apresentam anti-reação complementar. Dos 62 cães positivos, 21 testaram positivo em RSAT, ME-RSAT e/ou TIC. Em relação às amostras submetidas a PCR, 19% (48/252) resultaram positivas.


Conclusões: Apesar dos resultados obtidos pertencerem a amostras pré-selecionadas (não refletindo a ocorrência nacional), recolhidas de um grupo heterogêneo de cães, estes primeiros resultados preliminares sugerem uma baixa seroprevalência de infeção por B. canis, em Portugal. O estudo ainda está a decorrer com o objetivo de aumentar o número de amostras, a cobertura geográfica e a avaliação dos canis de criação em Portugal.

description: Policy making regarding biomass co-firing is difficult. The article provides a benefit-cost analysis for decision makers to facilitate policy making process to implement efficient biomass co-firing policy. The additional cost is the sum of cost of the biom ass procurement and biomass transportation. Co-benefits are sales of greenhouse gas emission credits and health benefit from reducing harmful air pollutants, especially particulate matter. The benefit-cost analysis is constructed for semi-arid U.S. region, Utah, where biomass supply is limited. Results show that biomass co-firing is not economically feasible in Utah but would be feasible when co-benefits are considered. Benefit-cost ratio is critically dependent upon biomass and carbon credit prices. The procedure to build the benefit-cost ratio can be applied for any region with other scenarios suggested in this study.
