Maaseutuväestön matkat muualle

2021

Analysoin artikkelissani maaseutuväestön liikkuvuutta 1840-luvun aikana kahdessa maaseutupitäjässä: Hämäläisessä Hollolassa ja karjalaisessa Jaakkimassa. Lähdeaineistona toimivat niin kutsutut annettujen todistusten diaarit, joihin papit kirjasivat muistiin heiltä pyydetyt erilaiset todistukset. Lähdeaineisto antaa kuitenkin vain tilaisuuden hahmottaa liikkuvuuden rajoja, sillä kirkon hallintoarkistoon kuuluvia annettujen todistusten diaareja ei ole pidetty tai säilynyt kovinkaan monesta seurakunnasta. Artikkelissani kysyn, ketkä yleensä lähtivät liikkeelle oman kotipitäjän ulkopuolelle, miksi ja millaisin todistuksin? Samalla selvitän liikkuvuuden kontrollointiin liittyviä yleisiä seikkoja…

Fracture toughness of different monolithic zirconia upon post-sintering processes

Fracture toughness (KIC) was determined with indentation fracture toughness method at load 1 kg for AG, FP…

Authentication and authorization security solution for the internet of thing

2021

The Internet of Things (IoT) represents the interconnection between the Internet and physical objects, places and environments. However, this extensive connectivity of IoT can be hampered by malicious interventions from cyber attackers. Thus, ensuring security for users and IoT devices remains a challenge, especially authentication and authorization, which are essential building blocks of the security process. This is due to the unconventional IoT characteristics, including scalability, heterogeneity, interoperability, and dynamic changes, which make the existing security measures inadequate. Indeed, these characteristics bring up several security requirements to consider when defining a se…

Transhumanismo, discurso transgénero y digitalismo: ¿exigencias de justicia o efectos del espíritu de abstracción?

2021

There are three great existential challenges for the human being in the present time: transhumanism, transgender discourse and digitalism. These three phenomena are enormously powerful today because they are driven by two overwhelming forces which, however, tend to collide opposing each other. On the one hand, they are encouraged by a demand for justice and emancipation, which seeks to end deeply rooted forms of discrimination and to seek effective equality among all human beings. On the other hand, they are sustained on a philosophical basis that denies the intelligibility of reality and the teleological condition of human existence, proposing instead, as the only guide to orient human lif…

Women in Aeschylean scene: a linguistic characterization

2021

Este trabalho examina os dispositivos linguísticos por meio dos quais Ésquilo conseguiu apresentar as personagens femininas da Oresteia. A análise é feita após um levantamento das seções recitativas de três tragédias; características fonéticas, morfológicas e sintáticas foram estudadas e comparadas com a linguagem dos personagens masculinos. Os resultados desta pesquisa se ajustam a outras tentativas precedentes de mostrar como a sociolinguística pode explicar o retrato formal dos personagens trágicos e cômicos.  This paper examines the linguistic devices by means of which Aeschylus achieved the presentation of the female characters of the Oresteia. The analysis is made after a survey of th…

Peer interaction and pioneering organizational form adoption : A tale of the first two for-profit stock exchanges

2021

Building on a historical case study on the first two stock exchanges to adopt the now globally dominant for-profit organizational form, the Stockholm Stock Exchange in 1993 and the Helsinki Stock Exchange in 1995, we argue that interaction among socially proximate peers contributes to pioneering organizational form adoption within an industry, particularly when such forms are introduced by established organizations. Peer interaction can induce a search for technically efficient organizational forms through the sharing of collective experiences, the establishment of collective assumptions, and a joint search for solutions. Together, these factors contribute to the legitimization of novel or…

Partially Coherent Optical Diffraction Tomography Toward Practical Cell Study

2021

Optical diffraction tomography (ODT) is a computational imaging technique based on refractive index (RI) contrast. Its application for microscopic imaging of weakly absorbing and scattering samples has been demonstrated by using a specially designed holographic microscope with angular scanning of the coherent sample illumination direction. Recently, an alternative low cost technique based on partially coherent sample illumination (PC-ODT), which is compatible with the conventional wide-field transmission microscope, has been established. In this case, the 3D refractive index distribution of the sample is obtained by deconvolution from a single stack of through-focus intensity images. The pe…

Nuclear moments put a new spin on the structure of 131In

2021

Abstract In spite of the high-density and strongly correlated nature of the atomic nucleus, experimental and theoretical evidence suggests that around particular 'magic' numbers of nucleons, nuclear properties are governed by a single unpaired nucleon1,2. A microscopic understanding of the extent of this behaviour and its evolution in neutron-rich nuclei remains an open question in nuclear physics 3-5. A textbook example is the electromagnetic moments of indium (Z = 49) 6, which are dominated by a hole with respect to the proton magic number Z = 50 nucleus. They exhibit a remarkably constant behaviour over a large range of odd-mass isotopes, previously interpreted as pure "single-particle b…

Technical note: sea salt interference with black carbon quantification in snow samples using the single particle soot photometer

2021

After aerosol deposition from the atmosphere, black carbon (BC) takes part in the snow albedo feedback contributing to the modification of the Arctic radiative budget. With the initial goal of quantifying the concentration of BC in the Arctic snow and subsequent climatic impacts, snow samples were collected during the research vessel (R/V) Polarstern expedition of PASCAL (Physical Feedbacks of Arctic Boundary Layer, Sea Ice, Cloud and Aerosol; Polarstern cruise 106) in the sea-ice-covered Fram Strait in early summer 2017. The refractory BC (rBC) content was then measured in the laboratory of the Alfred Wegener Institute with the single particle soot photometer (SP2). Based on the strong obs…

Differential effects of faces and words in cognitive control in older adults with and without major depressive disorder: An emotional Stroop task stu…

2021

Aging and major depressive disorders have been associated with impaired cognitive control. These deficits are also influenced by the affective valence and by the type of stimulus processed. Using an emotional Stroop task, the current study aims to examine cognitive control deficits and their association with emotion regulation in depression and the influence of the type of stimulus (words and faces) in this association. A total of 26 older patients with a major depressive disorder (MDD) (19 women; age range: 65-84 years) and 26 older healthy controls (18 women; age range: 65-80 years) participated in the study. The results showed that MDD individuals presented greater Stroop effects than th…

Il lascito del proprio corpo a fini didattici e di ricerca. Il nobile (ma vano) intento della legge 10/2020

2021

The essay gives a sharp outline of the recent Italian law ruling body donation to science after death, as a personal choice exclusively founds on a conscious and free act of will. The statute, however, has not been met its aim, lacking of supporting the donor in making his consent fully effective. Indeed, as one of the highest displays of human solidarity, this issue would have required a balance between scientific research interests and individual autonomy protection.

Biodegradation Potential of Oil-degrading Bacteria Related to the Genus Thalassospira Isolated from Polluted Coastal Area in Mediterranean Sea

2021

Three bacterial species related to the genus Thalassospira (T. lucentensis, T. xianhensis and T. profundimaris), isolated from polluted sediment and seawater samples collected from Priolo Bay (eastern coast of Sicily, Ionian Sea), were analyzed for their biotechnological potential. For this purpose, the presence of specific catabolic genes associated to aliphatic and aromatic hydrocarbon metabolism, the production of biosurfactants and emulsification activity, the capability to degrade oil-derived linear, branched, cyclic alkanes, and polycyclic aromatic hydrocarbons (PAHs) were evaluated. Alkane hydroxylase gene (alkano-monoxygenase alkb and citocrome P450) were present in genome of all st…

Design and Simulation of a Vision-Based Automatic Trout Fish-Processing Robot

2021

Today, industrial automation is being applied in a wide range of fields. The initial modeling of robots and mechanical systems together with simulation results in optimal systems. In this study, the designed system is simulated to obtain the required velocities, accelerations and torques of the actuating arms in a vision-based automatic system. Due to the slippery skin of fish and the low friction coefficient, it is not easy to design an optimal tool to handle fish. Since the fish-processing operation is undertaken step by step and provides fish stability, it is essential that the gripper enables different processing operations along the system. The proposed system performs belly-cutting, b…

An abstract inf-sup problem inspired by limit analysis in perfect plasticity and related applications

2021

This paper is concerned with an abstract inf-sup problem generated by a bilinear Lagrangian and convex constraints. We study the conditions that guarantee no gap between the inf-sup and related sup-inf problems. The key assumption introduced in the paper generalizes the well-known Babuška–Brezzi condition. It is based on an inf-sup condition defined for convex cones in function spaces. We also apply a regularization method convenient for solving the inf-sup problem and derive a computable majorant of the critical (inf-sup) value, which can be used in a posteriori error analysis of numerical results. Results obtained for the abstract problem are applied to continuum mechanics. In particular…

Peripheral CB1 receptor blockade acts as a memory enhancer through an adrenergic-dependent mechanism

2021

Peripheral inputs to the brain continuously shape its function and can influence the formation of non-emotional memory, but the underlying mechanisms have not been fully understood. Cannabinoid type-1 receptors (CB1R), widely distributed in the organism, is a well-recognized player in memory performance, and its systemic modulation significantly influences memory function. By assessing non-emotional memory in mice, we have now found a relevant role of peripheral CB1R in the formation of persistent memory. Indeed, peripherally restricted CB1R antagonism by using AM6545 showed a mnemonic effect that was occluded in adrenalectomized mice, after peripheral adrenergic blockade, or when vagus ner…

Conformational Dynamics of the Dengue Virus Protease Revealed by Fluorescence Correlation and Single-Molecule FRET Studies.

2021

The dengue virus protease (DENV-PR) represents an attractive target for counteracting DENV infections. It is generally assumed that DENV-PR can exist in an open and a closed conformation and that active site directed ligands stabilize the closed state. While crystal structures of both the open and the closed conformation were successfully resolved, information about the prevalence of these conformations in solution remains elusive. Herein, we address the question of whether there is an equilibrium between different conformations in solution which can be influenced by addition of a competitive inhibitor. To this end, DENV-PR was statistically labeled by two dye molecules constituting a FRET …

PROPOSAL OF FORMAL AND NON-FORMAL EDUCATION FOR NEW GENERATION DIGITAL LEARNING DEMAND IN ENGINEERING

2021

Millennial generation, starting from twelve-year-olds up to adolescents, is one of the most complicated generational cohorts; its ecosystem, beyond of formal and non-formal education boundaries, is more diverse than for any other previous generation. Digital learners prefer a digital learning environment, as the advantage of digital learning is the control over time, place, way and pace, enabling you to impersonate as an educational institution, applying smart personal network which consists of 3 domains: applied smart technologies; reflexive pedagogy for the digital century [1]; learning environment [2], thus without any confrontation of formal and non-formal education, but rather with con…

Tuning the Direct and Indirect Excitonic Transitions of h-BN by Hydrostatic Pressure

2021

The pressure dependence of the direct and indirect bandgap transitions of hexagonal boron nitride is investigated using optical reflectance under hydrostatic pressure in an anvil cell with sapphire windows up to 2.5 GPa. Features in the reflectance spectra associated with the absorption at the direct and indirect bandgap transitions are found to downshift with increasing pressure, with pressure coefficients of −26 ± 2 and −36 ± 2 meV GPa–1, respectively. The GW calculations yield a faster decrease of the direct bandgap with pressure compared to the indirect bandgap. Including the strong excitonic effects through the Bethe–Salpeter equation, the direct excitonic transition is found to have a…

Off on the wrong foot : Task avoidance at the outset of primary school anticipates academic difficulties and declining peer acceptance

2021

The present study examined the academic antecedents of declining peer social status. Participants included 545 (311 boys, 234 girls) Finnish students followed from the 1st through the 4th grade (ages 6–8 at outset). Each year, teachers completed assessments of academic task avoidance and students completed standardized measures of reading and math achievement. Acceptance was assayed through peer nominations. Supporting the hypothesized model, the results indicated that a lack of interest and motivation at the outset of primary school leads to a downward spiral of academic difficulties and diminished peer acceptance. Specifically, academic task avoidance in 1st and 2nd grade anticipated decl…

Viipuri liikkumisen keskuksena 1800-luvun alkupuoliskolla

2021

Viipuri oli rajakaupunkina 1800-luvun alkupuoliskollakin liikkumisen keskus, jonka kautta kulki runsain määrin matkustajia niin itään ja erityisesti Pietariin, kuin myös lännen suuntaan. Matkustaja- ja passirekistereiden kautta on mahdollista analysoida, mitä matkustusdokumentteja liikkujat käyttivät, ja keitä kulkijat olivat. Jossakin määrin aineisto mahdollistaa myös kurkistuksen kaupungissa tapahtuneeseen majoitustoimintaan ja vieraanvaraisuuteen. Tämän ohessa on mahdollista tehdä johtopäätöksiä matkaajien sukupuolesta ja sosiaalisesta asemasta, mutta kokonaisuudessaankin rekisterien tarjoama kuva liikkumisesta on ennen kaikkea suuntaa antava. Esimerkiksi passirekisterit kertovat vain pa…

Multi-field, multi-frequency bosonic stars and a stabilization mechanism

2021

Scalar bosonic stars (BSs) stand out as a multi-purpose model of exotic compact objects. We enlarge the landscape of such (asymptotically flat, stationary, everywhere regular) objects by considering multiple fields (possibly) with different frequencies. This allows for new morphologies ${\it and}$ a stabilization mechanism for different sorts of unstable BSs. First, any odd number of complex fields, yields a continuous family of BSs departing from the spherical, equal frequency, $\ell-$BSs. As the simplest illustration, we construct the $\ell$ = ${\it 1}$ ${\it BSs}$ ${\it family}$, that includes several single frequency solutions, including even parity (such as spinning BSs and a toroidal,…

Ceylon cinnamon and its major compound Cinnamaldehyde can limit overshooting inflammatory signaling and angiogenesis in vitro: implications for COVID…

2021

AbstractOvershooting immune reactions can occur during inflammatory responses that accompany severe infections, such as COVID-19. Cytokines, damage-associated molecular patterns (DAMPs), and reactive oxygen and nitrogen species can generate positive feedback loops of inflammation, leading to long-term complications such as vascular endothelialitis, thrombosis, endothelial dysfunction, neurological impairments, and chronic fatigue. Dexamethasone can limit inflammation by inhibiting the activation of pro-inflammatory transcription factors. High dose dexamethasone, however, has undesirable side effects. Here, we show that Ceylon cinnamon and its major compound cinnamaldehyde can mitigate infla…

ASSESSING MERCURY POLLUTION USING BLACK STORK EGGSHELLS

2021

Female birds whose bodies contain environmental contaminants produce eggs with shells that are likewise contaminated, making bird eggshells appropriate indicators for monitoring environmental toxins. Common contaminants include organic mercury compounds, especially methylmercury, which are known to bioaccumulate and biomagnify in the food chain. Black storks (Ciconia nigra) predominantly consume fish and are thus at risk for high mercury intake. In this study, we used eggshells of black storks as a proxy to reconstruct the concentration levels and distribution of mercury, a well-known toxic element, in various parts of Latvia. Preliminary analyses have shown that deposition levels of mercur…
