description: We compute the Rydberg spectrum of a single Ca$^+$ ion in a Paul trap by incorporating various internal and external coupling terms of the ion to the trap in the Hamiltonian. The coupling terms include spin-orbit coupling in Ca$^+$, charge (electron and ionic core) coupling to the radio frequency and static fields, ion-electron coupling in the Paul trap, and ion center-of-mass coupling. The electronic Rydberg states are precisely described by a one-electron model potential for e$^-$+Ca$^{2+}$, and accurate eigenenergies, quantum defect parameters, and static and tensor polarizabilities for a number of excited Rydberg states are obtained. The time-periodic rf Hamiltonian is expanded in the Floquet basis, and the trapping-field-broadened Rydberg lines are compared with recent observations of Ca$^+(23P)$ and Ca$^+(52F)$ Rydberg lines.

description: Objectives: The aim of this work was to study the effect of metaphylactic tulathromycin on the mortality of feedlot lambs in high-risk conditions (very hot weather).


Material and Methods: 2235 lambs arriving at a fattening unit in a very hot fortnight in Portugal (June 2022) were used. Animals were from different origins, 2-4 months old, and at arrival some were showing signs of respiratory disease. Lambs with official identification number (ID) ending in even numbers were allocated to the Control group (not treated, and no placebo) and odd numbers belonged to the Treatment group, and given tulathromycin (Draxxin 100mg/ml), 2.5mg/kg bodyweight, IM. All animals were subjected to equal husbandry and feeding. Date of death was recorded and number of days after arrival calculated. Treatment and Control groups were compared: mortality rate (Pearse Chi-square tes); and survival rate (Kaplan-Meier survival analysis).


Results: Mortality rate was 7.2% (82 out of 1132 animals) and 11.9% (131 out of 1102 animals) in Treatment and Control groups, respectively (p<0.001). Cause of death was not confirmed; however, ovine respiratory complex (ORC) is the main cause of death in fattening lambs. Mean number of days between death and arrival was 21.0 and 17.9 for Treatment and Control groups, respectively (p=0.039). The analysis did not take into consideration age, origin, or presence of clinical disease. Other variables could have been used to understand the impact on animal welfare; however, mortality related to ORC is associated with chronic disease and suffering.


Conclusions: Metaphylactic tulathromycin had a positive effect on the survival rate of lambs, therefore its use should be considered in high-risk conditions. This study should be repeated in mild weather conditions in order to understand if the differences persist between the groups, so metaphylaxis can only be applied to more specific situations and antimicrobial use is reduced.

description: The role of thermodynamics in continuum mechanics and the derivation of the proper constitutive relations is a discussed subject of Rational Mechanics. The classical literature did not use the accumulated knowledge of thermostatics and was very critical with the heuristic methods of irreversible thermodynamics. In this paper, a small strain gradient elasticity theory is constructed with memory effects and dissipation. The method is nonequilibrium thermodynamics with internal variables; therefore, the constitutive relations are compatible with thermodynamics by construction. Thermostatic Gibbs relation is introduced for elastic bodies with a single tensorial internal variable. The thermodynamic potentials are first-order weakly nonlocal, and the entropy production is calculated. Then the constitutive functions and the evolution equation of the internal variable is constructed. The second law analysis has shown a contribution of gradient terms to the stress, also without dissipation.

description: The emergence of the exit events from a bounded domain containing a stable fixed point induced by non-Gaussian Lévy fluctuations plays a pivotal role in practical physical systems. In the limit of weak noise, we develop a Hamiltonian formalism under the Lévy fluctuations with exponentially light jumps for one- and two-dimensional stochastic dynamical systems. This formalism is based on a recently proved large deviation principle for dynamical systems under non-Gaussian Lévy perturbations. We demonstrate how to compute the most probable exit path and the quasi-potential by several examples. Meanwhile, we explore the impacts of the jump measure on the quasi-potential quantitatively and on the most probable exit path qualitatively. Results show that the quasi-potential can be well estimated by an approximate analytical expression. Moreover, we discover that although the most probable exit paths are analogous to the Gaussian case for the isotropic noise, the anisotropic noise leads to significant changes of the structure of the exit paths. These findings shed light on the underlying qualitative mechanism and quantitative feature of the exit phenomenon induced by non-Gaussian noise.

description: This paper introduces an integrated educational model for higher education, ECOBI, which combines Educational Clusters (teaching programs), the Blended Intensive approach, and the issuance of Open Badges within university curricula. Adopted by EDUNEXT, a network of 35 Italian universities aimed at digital educational innovation and university network development, ECOBI proposes a competency-based design that makes degree courses and Educational Clusters planned to develop specific skills relevant to the 21st-century landscape. The Intensive Blended approach integrates online teaching activities with intensive in-person training weeks, combining the strengths of both experiences. This model offers modularity and flexibility, promotes interdisciplinary learning and interchangeability of content, and meets the needs of current higher education. The article describes the ECOBI approach, its characteristics, strengths and advantages, and highlights its implementation within the EDUNEXT network.

description: We present a calculation of the zeta function and of the functional determinant for a Laplace-type differential operator, corresponding to a scalar field in a higher dimensional de Sitter brane background, which consists of a higher dimensional anti-de Sitter bulk spacetime bounded by a de Sitter section, representing a brane. Contrary to the existing examples, which all make use of conformal transformations, we evaluate the zeta function working directly with the higher dimensional wave operator. We also consider a generic mass term and coupling to curvature, generalizing previous results. The massless, conformally coupled case is obtained as a limit of the general result and compared with known calculations. In the limit of large anti-de Sitter radius, the zeta determinant for the ball is recovered in perfect agreement with known expressions, providing an interesting check of our result and an alternative way of obtaining the ball determinant.

description: The fast evolution of technology makes digital competencies mandatories in all professional contexts. The authors conducted a study aiming to systematize the design and validation of an instrument to measure digital skills for research. The methodology included a literature review to identify the theoretical bases and the dimensions or components of digital skills and the design of the questionnaire. Secondly, its validity was tested through the Content Validity Index (CVI) with the judgment of six experts and the Exploratory Factor Analysis (EFA) after a pilot study with a sample of 96 researchers. Finally, Cronbach’s alpha coefficient test was performed to assess reliability. The results yielded the Kaiser-Meyer-Olkin (KMO) determined sampling adequacy (KMO= .830) and a significant Bartlett's sphericity test (p= .000). The anti-image matrix showed high values except for the first item that did not reach the critical threshold in the communality’s values; so, it was removed. The validity test showed a high content validity coefficient (IVC= .98). Regarding the EFA, the six-factor analysis revealed that nine out of the 14 items showed factor loading > 0.7. The reliability test also showed positive results (ɑ=.874). In conclusion, the results obtained in the present study validate the questionnaire as an accurate and reliable tool for assessing the digital competencies of researchers. This may be a useful tool in the initial phases of policy planning for strengthening scientific production and closing digital competencies gaps in universities.

description: The advent of technology may dramatically alter academic research and performance. This study uses the Unified Theory of Adoption and Use of Technology (UTAUT) and Task-Technology Fit (TTF) theories to examine how technology adoption influence Research Performance conducted with sample size of 1,354 South Indian private institution Assistant Professors, with perception as a moderating factor. The research uses Structural Equation Modelling (SEM) with SmartPLS 4.0 to reveal that Performance Expectancy (PE) greatly influence Behavioral Intention (BI) to adopt technology. Higher Performance Expectancy (PE) leads to a stronger intention to use technology. Effort Expectancy (EE) also boosts BI, emphasizing the role of usability in setting user intentions. Technology adoption depends on Social Influence (SI), along with peer and social norms affect BI. Effective technology adoption requires Facilitating Conditions (FC) and enough resources and infrastructure. Task Characteristics (TC) and Technology Characteristics (TCh) greatly alter Task-Technology Fit (TTF), which enhances research procedures. TTF improves research practices but hurts research performance, demonstrating that improved techniques do not necessarily translate to better performance ratings, highlighting the intricacy of task-technology compatibility and research results.

description: The present study attempted to investigate the integration of digital resources in research work by Indian higher education teachers. The success of the digital resources in research can be affected by several factors, such as digital skills, digital flow, anxiety in the use of ICT, digital ethics, quality of digital resources and the behavioral intention to integrate ICT and the relationship between the factors. An online survey originally constructed by Guillén-Gámez et al. (2023) was used to collect data, and the final sample used for this study was 347 teachers of Universities in Punjab, India. Data analysis and hypotheses testing were done using partial least squares structural equations modeling (PLS-SEM). All the hypotheses are supported except hypothesis 10 implying that the quality of technological resources did not influence integration. The total of the factors corresponded to 65.6% of the variance in the integration of ICT in the research process. The results confirm that the model proposed by Guillén-Gámez et al. (2023) in the Spanish context, is effective in the Indian higher Education context in explaining the technological integration of teachers to use ICT in research work. The findings of this study open the possibilities for researchers in India to find out the reasons for the above results by conducting qualitative or mixed-method research in the context of the use of ICT in the Indian higher education landscape.

description: We present time-resolved optical and ultraviolet spectroscopy and photometry of V1460~Her, an eclipsing cataclysmic variable with a 4.99\,h orbital period and an overluminous K5-type donor star. The optical spectra show emission lines from an accretion disc along with absorption lines from the donor. We use these to measure radial velocities, which, together with constraints upon the orbital inclination from photometry, imply masses of $M_1=0.869\pm0.006\,\mathrm{M}_\odot$ and $M_2=0.295\pm0.004\,\mathrm{M}_\odot$ for the white dwarf and the donor. The radius of the donor, $R_2=0.43\pm0.002\,\mathrm{R}_\odot$, is $\approx 50$ per cent larger than expected given its mass, while its spectral type is much earlier than the M3.5 type that would be expected from a main sequence star with a similar mass. HST spectra show strong $\mathrm{N{\small V}}$ 1240 A emission but no $\mathrm{C{\small IV}}$ 1550 A emission, evidence for CNO-processed material. The donor is therefore a bloated, over-luminous remnant of a thermal-timescale stage of high mass transfer and has yet to re-establish thermal equilibrium. Remarkably, the HST ultraviolet data also show a strong 30 per cent peak-to-peak, $38.9\,$s pulsation that we explain as being due to the spin of the white dwarf, potentially putting V1460 Her in a similar category to the propeller system AE Aqr in terms of its spin frequency and evolutionary path. AE Aqr also features a post-thermal timescale mass donor, and V1460 Her may therefore be its weak magnetic field analogue since the accretion disc is still present, with the white dwarf spin-up a result of a recent high accretion rate.

description: Objectives: E. europaeus has been used as a sentinel of different One Health concerns, including heavy metal(loid)s pollution or zoonotic pathogens. This work aims to study trace elements’ health effects, performing a toxicology and histopathology assessment with hedgehogs.


Materials and Methods: Forty-six hedgehogs from three Portuguese rescue centres (CERVAS, LxCRAS and RIAS) were submitted to necropsy. Sex and age group were visually estimated. A liver sample was stored in a 10% formalin container for histopathology routine examination. Another liver portion was collected into a zip bag and stored under -20ºC. Then, it was completely freeze-dried for two days at -56ºC (LaboGene CoolSafe®) and stored frozen until further analysis. Acid digestion was performed in a digestion plate (DigiPrep-MS®) and metal(loid)s concentrations (As, Cd, Cr, Cu, and Pb) was determined with inductively coupled plasma mass spectrophotometry (ICP-MS).


Results: High levels of Cu were found in the liver (35.66 ± 19.65 mg kg-1 dry weight [dw]), with some animals passing 100 mg kg-1 dw, which is a consistently high value for insectivores. Biliary hyperplasia was the most frequent lesion observed, in 36% of the analyzed livers. Animals presenting biliary hyperplasia show higher levels of metal(loid)s (with the exception of As), with a significant difference for Cd (p=0.007) and Co (p=0.019). No statistically significant associations were found between biliary hyperplasia and age or sex.


Conclusions: Exposure to metal(loid)s may be a cause of biliary hyperplasia, though other analyses (including the use of biochemistry methods) are needed to confirm this hypothesis. To the authors’ knowledge, this was the first report of this association in hedgehogs. Further research (including different organs and locations) is crucial to understand the impact of metal(loid)s pollution in Portugal.

description: The teaching profession in higher education demands strong research skills, and with rapid technological advancements, university teaching professionals must familiarize themselves with digital research skills. Thus, university teachers and PhD research scholars across the globe are eager to develop their digital research skills to enhance their work efficiency. Acquiring digital research skills on the job or during the PhD program has proven to be challenging. These skills assist higher education professionals in various ways, such as supervising doctoral students, conducting research, working on research projects, and publishing research articles.
Thus, the present study attempted to provide ICT-integrated modular training (MT) to facilitate the higher education teaching faculty and PhD scholars with digital research skills. The study employed a repeated cross-sectional research design and measured the effectiveness of the MT through a single group pre and post-test design. Researchers conducted three modular training sessions annually on digital research skills over five consecutive years. In total, 300 scholars attended the training and participated in the pre-test, post-test, and satisfaction survey. Findings from paired sample t-tests (t-value varied between 4.117 to 7.525, p < 0.05) revealed that modular training has been significantly effective with a large effect size (d > 0.8).
Furthermore, the satisfaction survey revealed a high degree of satisfaction among participants. Future research may explore ways to strengthen the technological and pedagogical content knowledge of modular training programs in developing digital research skills.

description: Learning Space is the physical and psychological place of acquiring knowledge, which has evolved significantly, influenced by technological advancements, pedagogical shifts, and changing student needs. The transformation of learning spaces is crucial for fulfilling the needs of the 21st generation learners and improving the learner’s overall outcome. This study aims to explore the available literature on learning spaces to analyse the past, current and future trends of study themes, in learning spaces, through a bibliometric analysis approach. Vos viewer software is used to determine the author, countries, and publications, which have made the greatest contribution to learning spaces research, as well as the key themes and emerging trends of study. The findings of the study show that most of the learning space research is focused on the user experience in traditional and digitally equipped learning spaces, the impact of learning spaces on users’ cognition, attitude, engagement, performance and well-being, and the design of innovative learning spaces. Still, there is a lack of research on the design and utilization of spaces to satisfy the needs of the 21st-century digital generation, for the well-being of the learner, and improvement of learning outcomes. The emerging theme of research is focused on the learner’s mental, physical and social well-being. This study will help the researchers to understand the research gap in the field of learning space research.

description: Focus of this Master Thesis is finding the solution for problem of “Not the right team” which arises as one of major reasons why early stage companies (start-ups) failed. Team formation, as a structural source of the problem, highly affects future life of a company; therefore, its process should be done very carefully. Examining structure of start-ups and looking deeply into the problem, Team formation is segmented on aspects of Team alignment, Team balance and Team heterogeneity which are then further analysed. Innovative approach is created using insights from analogous distant field. In that sense, connections between sports and start-ups are established. Exploration showed that basketball is the best field from which valuable insight could arise. Specific connections between basketball and start-up are explained having in mind targeted Team formation aspects. Statistical analysis using hierarchical multiple regression is conducted to explore if observed Team formation aspects significantly contribute to team success in basketball. Results show there is statistically significant explanation of team success done by Alignment and Team balance variables. It gives scientifically grounded opportunity to transfer practices and knowledge from one field to another.

description: Spaceborne remote sensing performs a significant role today in geological mapping, interpretation and analysis of large areas in a rapid and cost-efficient manner. Spaceborne satellite imagery have been successfully utilized in lithological mapping of arid areas, however, similar approaches for lithological mapping in semi-arid regions with high degree of structural complexity, vegetation and topographic effects are yet to be developed. The primary objective of this study is to combine field-based spectroscopic research with geological remote sensing in obtaining representative lithological maps of the Buëch area in South-East France. To achieve this aim Support Vector Machine (SVM) classifier and Spectral Angle Mapper (SAM) were used on Sentinel-2 and ASTER imagery. Spectroscopic examination of field samples enabled the creation of spectral endmembers representative for the area and detection of local weathering mechanisms. The results derived from SVC classifier showed great pattern-recognition ability and more accurate classification of different lithological groups. SAM derived thematic mapper demonstrated the ability to correctly classify a great portion of blue marl outcrops, by recognising the lack of spectral response displayed by blue marls as being the distinctive indicator of the class. Using and evaluating different satellite imagery shows that Sentinel-2 allows better mapping in this semi-arid area, indicating that the higher spatial resolution of Sentinel-2 has an edge over the higher spectral resolution in the SWIR range of ASTER for this specific setting and methodology. The study has shown that field-based spectroscopic research complements geological remote sensing well. The limiting factor in achieving better classification is the spectral and spatial properties of the satellite imagery. Therefore, future research should consider the integration of hyperspectral data and assimilation of geomorphic products to increase the accuracy of lithological unit discrimination.

description: Objetivos: Giardia duodenalis é um protozoário oportunista, com potencial zoonótico. São escassos os dados relativos à caracterização molecular do parasita em gatos. O presente estudo teve como objetivo determinar a prevalência da infeção por Giardia duodenalis em gatos da Área Metropolitana de Lisboa (AML) e explorar possíveis fatores de risco associados. 


Métodos: Entre novembro de 2022 e fevereiro de 2023, foram obtidas amostras fecais de gatos domésticos, gatos de criadores e gatos errantes/abrigo, da AML. A pesquisa de quistos de Giardia duodenalis foi realizada pelo método de flutuação com centrifugação modificado.


Resultados: A infeção por Giardia duodenalis foi detetada em 10,3% (9/87) dos gatos amostrados. A análise estatística revelou que os gatos com perda de consistência fecal (odds ratio = 17,231; p<0,001) e errantes/abrigo (odds ratio = 16,501; p<0.001) apresentam um risco significativamente superior de infeção.


Conclusões: O presente estudo demonstra que a prevalência da infeção por Giardia duodenalis em gatos não é negligenciável, sugerindo-se, adicionalmente, que a perda de consistência fecal e o estilo de vida possam ser preditores da infeção nestes felídeos. Estudos adicionais de genotipagem devem ser realizados, por forma a avaliar a circulação de assemblages zoonóticas e, consequentemente, o risco para a saúde pública.

description: Gamma Ray Burst (GRBs) are empirically classified as long-duration GRBs (LGRBs, $>$ 2s) and short-duration GRBs (SGRBs, $0$). The only confirmed Type I GRB, GRB 170817A, has log $O({\rm II:I})=-10$. According to this criterion, the supernova-less long GRBs 060614 and 060505 belong to Type I, and two controversial short GRBs 090426 and 060121 belong to Type II.

The Impact of Land Fragmentation on Rice Production Cost and Factor Demands

Subjects: Land Economics/Use

description: Land fragmentation, in which a farm operates several separate plots of land, is a common phenomenon in Japan. It is generally agreed that the existence of fragmentation causes cost increment by increasing time and fuel for traveling between plots, or labor hours for water management, weeding, and so on. However its quantitative impacts on these inputs or production cost have not been clarified yet. This article estimated these impacts using panel data of Japanese rice farms. Empirical results reveal that fragmentation increases production costs and offsets economies of size, and that these impacts are especially strong for large size farms. For a long time, the Japanese government has aimed to increase farm size, but as the farm gets larger, emphasis should be switched from increasing size to the settlement of fragmentation, since the harmful effects of fragmentation increase sharply. Moreover, it was demonstrated that fragmentation increases not only fuel inputs or labor hours for planting, weeding or harvesting, as generally accepted, but also managerial labor such as bookkeeping or meeting, and materials such as fertilizers or pesticides, probably caused by substitution effects from labor. The range of fragmentation's impacts is spread beyond our scope. The latter results especially have an important policy implication: the settlement of fragmentation will bring not only the reduction of production cost but also an environmental benefit by reducing fertilizers or pesticides.

Year: 2024

description: Objetivos: O principal objetivo deste estudo foi estabelecer uma relação entre os valores obtidos pela aplicação do protocolo QBA e as alterações de quantidade e qualidade de leite produzido.


Materiais e métodos: PROTOCOLO QBA (QUALITATIVE BEHAVIOUR ASSESSMENT): Protocolo de medidas qualitativas que se baseia na capacidade humana de interpretação e observação do comportamento e estado emocional do animal obtendo a sua classificação numa escala visual. Como tal, realizaram-se auditorias numa exploração pecuária portuguesa de vacas leiteiras para avaliação dos animais, segundo este mesmo protocolo. PERFORMANCE PRODUTIVA: Consulta, via Lacticoop, dos valores referentes a Ureia, TB, TP e CCS – medidores escolhidos para medir a qualidade do leite – e também as quantidades de leite produzidas diariamente. Para a análise estatística recorreu-se ao programa RStudio, na tentativa de se estabelecerem correlações, aplicando-se a correlação de Spearmen com nível de significância de 5%.


Resultados: .Não se estabeleceram correlações com nível de significância suficiente para serem consideradas hipóteses. Apenas foi possível concluir que a quantidade de leite produzido está positivamente relacionada com a percentagem de teor proteico do mesmo. •        Tendencialmente, o QBA e a quantidade de leite produzido apresentam valores mais elevados quando os animais não são manuseados extra rotina, os operadores não circulam pelos parques e a temperatura ambiente está amena ou são tomadas medidas para evitar o stress térmico dos animais.


Conclusões: O desenvolvimento de futuros estudos neste âmbito revelar-se-ia interessante para a perceção da relação na variação ou ausência de variação do protocolo QBA assente em parâmetros meteorológicos e em diferentes tipos de maneio.

description: We use the Analytic Hierarchy Process (AHP) and the Cost Benefit Analysis (CBA) to evaluate the profitability and sustainability of aquaculture in Jamaica. We also examine the combined application of these methods to provide holistic and reliable information. In March 2010 we administered the AHP and the CBA survey instruments among 27 Jamaicans engaged in large- and medium-scale tilapia production and marketing. The overall ranking of criteria is reliable, with an inconsistency ratio (IR) of 0.075. Participants classified ‘better feed conversion ratio’ as their first criteria for increasing profitability and sustainability, with a rank score (RC) of 0.050. In second and third places were ‘decreased disease problems’ and ‘decreased mortality,’ with RCs of 0.036 and 0.031, respectively. The net operating income ($33,103.05), the IRR of 30.36% and P.I of 1.55 shows that tilapia production is profitable and feasible. When participants’ preferences of methods for improving fish production and marketing from the AHP results were considered, fish production and marketing in Jamaica became more profitable and sustainable. The results show that the AHP method provides unique ranking of stakeholders’ preferences and, when combined with the CBA, generates solid analyses for evaluating the profitability and sustainability of aquaculture enterprises.

description: The aim of this article is to provide space level maps between configuration spaces of graphs that are predicted by algebraic manipulations of cellular chains. More explicitly, we consider edge contraction and half-edge deletion, and identify the homotopy cofibers in terms of configuration spaces of simpler graphs. The construction's main benefit lies in making the operations functorial - in particular, graph minors give rise to compatible maps at the level of fundamental groups as well as generalized (co)homology theories. As applications we provide a long exact sequence for half-edge deletion in any generalized cohomology theory, compatible with cohomology operations such as the Steenrod and Adams operations, allowing for inductive calculations in this general context. We also show that the generalized homology of unordered configuration spaces is finitely generated as a representation of the opposite graph minor category.
