Description of movement sensor dataset for dog behavior classification
2022
The description and results of the original investigation are found in: Dog behaviour classification with movement sensors placed on the harness and the collar, Kumpulainen, P., Valldeoriola Cardó, A., Somppi, S., Törnqvist, H., Väätäjä, H., Majaranta, P., Gizatdinova, Y., Antink, C. H., Surakka, V., V. Kujala, M., Vainio, O. & Vehkaoja, A., Aug 2021, In: Applied Animal Behaviour Science. 241, 7 p., 105393. Movement sensor data from seven static and dynamic dog behaviors (sitting, standing, lying down, trotting, walking, playing, and (treat) searching i.e. sniffing) was collected from 45 middle to large sized dogs with six degree-of-freedom movement sensors attached to the collar and the ha…
Transfer of Immunity from Mother to Offspring Is Mediated via Egg-Yolk Protein Vitellogenin.
2015
Insect immune systems can recognize specific pathogens and prime offspring immunity. High specificity of immune priming can be achieved when insect females transfer immune elicitors into developing oocytes. The molecular mechanism behind this transfer has been a mystery. Here, we establish that the egg-yolk protein vitellogenin is the carrier of immune elicitors. Using the honey bee, Apis mellifera, model system, we demonstrate with microscopy and western blotting that vitellogenin binds to bacteria, both Paenibacillus larvae – the gram-positive bacterium causing American foulbrood disease – and to Escherichia coli that represents gram-negative bacteria. Next, we verify that vitellogenin bi…
Practices in research, surveillance and control of neglected tropical diseases by One Health approaches: A survey targeting scientists from French-sp…
2021
One health (OH) approaches have increasingly been used in the last decade in the fight against zoonotic neglected tropical diseases (NTDs). However, descriptions of such collaborations between the human, animal and environmental health sectors are still limited for French-speaking tropical countries. The objective of the current survey was to explore the diversity of OH experiences applied to research, surveillance and control of NTDs by scientists from French-speaking countries, and discuss their constraints and benefits. Six zoonotic NTDs were targeted: echinococcoses, trypanosomiases, leishmaniases, rabies, Taenia solium cysticercosis and leptospiroses. Invitations to fill in an online q…
The invasive potential of Prussian carp in Finland under the light of a novel semi-clonal reproductive mechanism
2013
Ryhmä samaan Carassius -sukuun kuuluvia kaloja on kotiutunut Eurooppaan pääasiassa viime vuosisadalla. Tämän ryhmän koostuessa suvullisesti ja suvuttomasti lisääntyvistä sekä eri ploidioita omaavista komplekseista perinteisen lajikäsitteen soveltaminen on erittäin hankala. Polyploidiset, suvuttomasti lisääntyvät muodot on useimmiten yhdistetty synonyymin Carassius (auratus) gibelio alla, joka on yleisesti tunnettu hopearuutanana. Diploidit, suvullisesti lisääntyvät muodot luokitellaan usein samaan lajiin kuuluviksi. Kun laji levisi Euroopassa, on havaittu lajin vahvoja vaikutuksia ekosyysteemeihin ja erityisesti sukunsa ainoaan eurooppalaiseen lajiin, ruutanaan. Tässä tutkimuksessa Suomeen …
Hudožestvennoe ubranstvo cerkvej Valaamskogo monastryrâ XVII - načala XIX veka
2016
The collection of church art of the Valamo monastery belongs to worthy rarities. Due to the evacuation from Karelia to Finland, collection survived almost complete. Despite the fact that the collection is well known to specialists in Finland and Russia, the research processes is just beginning. Especially little information exists about the icons of earlier period than of the 18th century. Almost nothing is known about the number of them, neither origins nor something about the painters of them. Many icons of the 18th century from the Valamo’s collection decorated the monastery churches. For this reason, the focus of this dissertation is the decoration of the main interiors of the Cathedral…
A non-canonical chemical feedback self-limits nitric oxide-cyclic GMP signaling in health and disease
2018
Endothelial nitric oxide (NO) stimulates the heme protein, soluble guanylyl cyclase (sGC) to form vasoprotective cyclic GMP (cGMP). In different disease states such as pulmonary hypertension, NO-cGMP signaling is pharmacologically augmented, yet the pathomechanisms leading to its dysregulation are incompletely understood. Here we show in pulmonary artery endothelial cells that endogenous NO or NO donor compounds acutely stimulate sGC activity, but chronically down-regulate both sGC protein and cGMP formation. Surprisingly, this endogenous feedback mechanism was independent of canonical cGMP signaling via cGMP-dependent protein kinase. It did not involve thiol-dependent modulation, a process…
Myocardial Glutathione Alterations in Acute Coronary Occlusion in the Dog
1987
Glutathione (GSH) decreases in dog mycocardium upon acute coronary occlusion when compared with sham-operated dogs. Total glutathione content (GSHeq = GSH + ZGSSG) remains unchanged throughout the experiment (6 h after surgery) in both sham- and acute coronary occlusion-operated dogs. GSSG and GSH/GSSG ratio increases and decreases respectively in all animals but tends to reach the normal value after 6 h in sham-operated dogs. Both parameters (GSSG and GSH/GSSG ratio) remain altered in acute coronary occlusion-operated ones. This alteration of glutathione status in ischemic myocardium is discussed.
"Sprawa Bourgeta" – czyli co właściwie łączy Sienkiewiczowskie "Bez dogmatu" z Bourgetowskim "Le Disciple"?
2018
It is a common critical tradition to compare a Polish novel and a French one. The article attempts to examine this phenomenon and to State exactly what (or no) relations between both texts, by searching critical judgments of the time and by analyzing the same texts’ level. There are following parallels (typologically, but not genetically determined) to be confirmed: anti-positivist and idealistic attitude of both authors, which have seen their texts as manifestos of outlook ; an intertextual potency of the novels, close related to their hypo- and hypertexts; as well as several, although superficial similarities of stories’ plots. The most convincing, however, there are the real differences:…
Endogenous firm asymmetry and cooperative R&D in linear duopoly with spillovers
2005
In a linear model ofcost reducing R&D/Cournot competition, firm asymmetry is shown to be sustainable as subgame perfect Nash equilibrium with R&D competition only ifthe productivity of research is sufficiently large relative to the benefits from imitation. In such a case, industry-wide cost reduction and firms asymmetry are increasing and decreasing functions of the spillover rate, respectively. In the absence of spillovers, a symmetric joint lab generates higher consumer surplus and social welfare than a pair ofasymmetric competitors. If spillovers are not too small, asymmetric R&D competition is advantageous toconsumers, but not to firms.
Neoclassical Growth, Environment and Technological Change: The Environmental Kuznets Curve
2009
The paper investigates socially optimal patterns of economic growth and environmental quality in a neoclassical growth model with endogenous technological progress. In the model, the environmental quality affects positively not only to utility but also to production. However, cleaner technologies can be used in the economy whether a part of the output is used in environmentally oriented R&D. In this framework, if the initial level of capital is low then the shadow price of a cleaner technology is low relative to the cost of developing it given by the marginal utility of consumption and it is not worth investing in R&D. Thus, there will be a first stage of growth based only on the accumulati…
