Skolotāju sadarbība starppriekšmetu saiknes veicināšanai projekta “Skola 2030” perspektīvā
2018
Maģistra darba mērķis ir noskaidrot, vai skolotāju savstarpējā sadarbība veicina starpnozaru saišu ieviešanu projekta "Skola 2030" ietvaros. Jaunā projekta nozīme ir kļuvusi aktuāla, jo šobrīd dominējoši fragmentārā un pasīvā mācību sistēma ir nepietiekama skolēnam, lai mācītos un dzīvotu 21.gadsimta sociālajā vidē, kurai ir raksturīgas straujas pārmaiņa sabiedrībā un digitālajā vidē. Lai attīstītu dzīvei nozīmīgas iemaņas un prasmes, Valsts izglītības satura centrs uzsāka projektu "Skola 2030". Maģistra darbā tika veikts pētījums vienā Rīgas vidusskolā par sadarbības fenomenu un starpnozaru saišu ieviešanu skolā. Šim mērķim tika izveidots četru soļu fenomenoloģiskais pētījums: stereotipu l…
The influence of soft acidic drinks in exposing dentinal tubules after non-surgical periodontal treatment: a SEM investigation on the protective effe…
2007
Objective: The aim of this study was to investigate the different smear layer morphologies produced by instrumentation with a hand curette and a periodontal sonic scaler for potential removal by soft acidic solution. The effect of a new oxalate-containing phytocomplex spray in preventing tubules exposure after citric acid solution application was also evaluated. Methods: Thirty recently extracted human teeth were used to obtain root dentinal fragments and divided in two groups: Curette treatment (CRT) root planed applying 30 working strokes to each surface using a Gracey?s curette 5-6 and Ultrasonic scaler (USC) treated using a periodontal scaler mounted on an ultrasonic hand-piece for 30 s…
La gestión en educación física. Dos modelos de gestión, el mismo individuo
2020
In the development of this writing, we intend to critically analyze the idea of management in Physical Education and problematize it with the issues of inclusion and inequality. To do this, first there is a brief etymological review of the concept of management, and then we analyze how Physical Education links management to economic and business Sciences. The analysis material used are books, manuals and articles on Physical Education management. From the analysis of this material, the second point of the work arises to explain two management models in Physical Education that we call: individual management and self-management. These models are presented as different and opposite, but in the…
A cross-cultural study using Napping (R): Do Korean and French consumers perceive various green tea products differently?
2013
http://www.elsevier.com/locate/foodres ; WOS:000323239400065; International audience; With the increasing demands of global trading, interests in cross-cultural comparisons have increased to gain understanding in the differences of sensory perception and consumer acceptability. The objective of this study was to compare the differences in perception by Korean and French consumers of green tea produced in Korea, China, and Japan, using Napping (R) followed by ultra flash profile. In addition, overall acceptability was examined in both countries. The results of Napping (R) showed that the Korean consumers were able to discriminate the green teas according to their origins and processing metho…
Microorganisms of food ice cubes and their transfer to drinks
2017
The present work was carried out to investigate the microbiological characteristics of the ice cubes produced at different levels: 1) home-made (HM) from domestic freezers; 2) produced by ice machines in bars and pubs (BP); 3) produced by ice industries (IN). BP samples were collected from the box stocks. HM and BP samples were transferred into sterile stomacher bags. IN samples were provided in the manufacturers’ plastic bags. Samples were transported into thermal insulated boxes. Five samples per each production level, forming a total of 15 samples (HM1-HM5, BP1-BP5, IN1-IN5), were collected in duplicate in two consecutive months. Each ice sample was thawed in 1 L sterile Dhuram’s bottle …
When even money can't buy - ice sports conditions in Oulu
2013
Tässä tutkimuksessa selvitetään nykyisen jäähallikapasiteetin riittävyyttä. Lisäksi tutkimuksessa selvitetään kuntaliitoksen vaikutusta jäähallien käyttäjiin sekä mahdollisuuksia lisätä ulkokaukaloiden käyttöä nykyisestä. Tutkimuksen kohderyhmänä on jäähallien asiakaskunta, eli urheiluseurat sekä rekisteröitymättömät ryhmät, kuten esimerkiksi työpaikkaryhmät ja puulaakijoukkueet. Perusjoukkona tutkimuksessa ovat kunnallisista jäähalleista ja Raksilan harjoitushallista vuoroja hakeneet tahot sekä harrastesarjoja pelaavat ryhmät (N=149). Tutkimusmenetelmä on survey-tutkimus. Nykyiset jäähalliolosuhteet eivät ole riittävät lasten ja nuorten liikuntaan ja urheiluun. Suurin osa urheiluseuroista …
History Matters: Colonial‑Based Connectivity and Foreign Headquarter Location Choice
2022
AbstractIn this study, we argue that European countries’ extensive relationships with former colonies represent a location factor that attracts foreign headquarter investments. The strategic role of foreign headquarters as coordinators, opportunity detectors, and global bridgeheads makes the location choice of headquarter activities sensitive to historical-based institutional connections. Drawing on a sample of 2230 foreign headquarter investments in Europe, we find that the stronger the combined effect of historical connections and current economic relationships with former colonies, the higher the probability of attracting headquarter investment projects. We refer to this combined charact…
Intrinsic spin-orbit interaction in diffusive normal wire Josephson weak links: Supercurrent and density of states
2015
We study the effect of the intrinsic (Rashba or Dresselhaus) spin-orbit interaction in superconductor--nanowire--superconductor (SNS) weak links in the presence of a spin-splitting field that can result either from an intrinsic exchange field or the Zeeman effect of an applied field. We solve the full non-linear Usadel equations numerically and analyze the resulting supercurrent through the weak link and the behavior of the density of states in the center of the wire. We point out how the presence of the spin-orbit interaction gives rise to a long-range spin triplet supercurrent, which remains finite even in the limit of very large exchange fields. In particular, we show how rotating the fi…
Anatomiskās, morfoloģiskās un fizioloģiskās izmaiņas kukurūzai (Zea mays L.) un lauka pupām (Vicia faba) cinka ietekmē
2017
Piesārņojums ar smagajiem metāliem ir aktuāla pasaules mēroga problēma, kas galvenokārt saistīta ar metalurģijas un intensīvās lauksaimniecības attīstību un tās radītajām sekām. Pētījumu veica Latvijas Universitātes Bioloģijas fakultātes Augu Fizioloģijas katedrā laika posmā no 2015. gada oktobra līdz 2017. gada maijam. Šī darba mērķis bija izpētīt dažādu cinka koncentrāciju substrātā ietekmi uz augu morfoloģiskajām, anatomiskajām un fizioloģiskajām izmaiņām, kā modeļobjektus izmantojot lauka pupu (Vicia faba) un kukurūzu (Zea mays). Pētījumā atklājās, ka lauka pupās un kukurūzā hlorofila koncentrācija lapās variantos ar mazu cinka koncentrāciju palielinās, bet variantos ar lielu cinka konc…
Voisinages tubulaires épointés et homotopie stable à l'infini
2022
We initiate a study of punctured tubular neighborhoods and homotopy theory at infinity in motivic settings. We use the six functors formalism to give an intrinsic definition of the stable motivic homotopy type at infinity of an algebraic variety. Our main computational tools include cdh-descent for normal crossing divisors, Euler classes, Gysin maps, and homotopy purity. Under-adic realization, the motive at infinity recovers a formula for vanishing cycles due to Rapoport-Zink; similar results hold for Steenbrink's limiting Hodge structures and Wildeshaus' boundary motives. Under the topological Betti realization, the stable motivic homotopy type at infinity of an algebraic variety recovers…
