Darba samaksas ienākumi un nodokļu piemērošanas problēmas un risinājumi
2018
Katru gadu Latvijā tiek ieviestas jaunas izmaiņas nodokļu sistēmā un to piemērošanā. 2018. gadā tika ieviesta nodokļu reforma. Šī reforma skar visus iedzīvotājus. Īpaši darba ņēmējus un darba devējus. Darba mērķis ir, balstoties uz normatīvo aktu, literatūras avotu un interneta resursu izpēti, noskaidrot, kā nodokļi ietekmē darba samaksu gan darba ņēmējam, gan darba devējam, kādas ir problēmas un risinājumi to piemērošanā. Izvirzītā mērķa sasniegšanai autore izpētīja dažādus avotus par darba samaksu un nodokļiem, kas to ietekmē, veica aprēķinus par darba algām, izdarīja secinājumus par nodokļu piemērošanu un izteica iespējamos risinājumus.

Darba rezultātā var secināt, ka darba samaksas sistēma Baltijas valstīs ir atšķi…
Production of neutron-rich surface-ionized nuclides at PARRNe
2002
Yields of neutron-rich isotopes produced by fast neutron induced fission of 238 U were measured at the ISOL set-up Production dAtomes Radioactifs Riches en Neutrons. A surface ion source was used to ionize selectively elements with low ionization potentials. In order to observe also the most n-rich isotopes, the identification was achieved by a combined measurement of b- and c-rays and b-delayed neutrons. The flux of fast neutrons inducing fission was generated by a 1 lA beam of 26 MeV deuterons stopped in a graphite converter. The target was a standard ISOLDE type 238 UC
Delayed-neutrons from arsenic isotopes 84As, 85As and 86As
1973
Abstract Short-lived arsenic isotopes were produced by thermal-neutron fission of 235U and isolated within 2·5 sec by volatilization of arsenic hydride. The existence of a strong delayed-neutron precursor of 2·05±0·05 sec half-life among the arsenic isotopes is confirmed and its assignment to 85As ascertained by milking of the daughter product 33 sec 85Se and 3·1 min 84Se, which is the final nucleus in the neutron decay branch of 85As. A delayed-neutron yield of 7·8 ± 1·2 neutrons/104 fissions was obtained for 85As. A new isotope, 0·9 ± 0·2 sec 86As, was detected by delayed-neutron counting and by following the decay of its most prominent γ-ray. The mass assignment was verified by milking o…
Improvements on Decay Heat Summation Calculations by Means of Total Absorption Gamma-ray Spectroscopy Measurements
2011
The decay heat of fission products plays an important role in predictions of the heat released by nuclear fuel in reactors. In this contribution we present results of the analysis of the measurement of the beta decay of some refractory isotopes that were considered possible important contributors to the decay heat in reactors. The measurements presented here were performed at the IGISOL facility of the University of Jyvaeskylae, Finland. In our measurements we have combined for the first time a Penning trap (JYFLTRAP), which was used as a high resolution isobaric separator, with a total absorption spectrometer. The results of the measurements as well as their consequences for decay heat sum…
Fission product yields at intermediate energy
1998
The results of experimental and theoretical studies of fission product yields in proton-induced fission of 238U are presented. The yields of neutron-rich Ni, Cu, Zn, Ga and Ge—isotopes were measured by 25 MeV protons and the ion guide-based isotope separator technique. The pre-neutron emission fragment mass distributions were measured by protons at energies Ep=20, 35, 50 and 60 MeV using time-of-flight method. The results indicate enhancement for superasymmetric mass division at intermediate excitation energy of the fissioning nucleus. A model calculation of fission products yields for fission of 238U by protons and neutrons is presented which predicts the formation cross sections for neutr…
Production of Sn and Sb isotopes in high-energy neutron induced fission of natU
2018
The first systematic measurement of neutron-induced fission yields has been performed at the upgraded IGISOL-4 facility at the University of Jyväskylä, Finland. The fission products from high-energy neutron-induced fission of nat U were stopped in a gas cell filled with helium buffer gas, and were online separated with a dipole magnet. The isobars, with masses in the range A = 128-133 , were transported to a tape-implantation station and identified using γ -spectroscopy. We report here the relative cumulative isotopic yields of tin (Z = 50) and the relative independent isotopic yields of antimony (Z = 51). Isomeric yield ratios were also obtained for five nuclides. The yields of tin show a …
Yhdessä opettaen ja oppien : mitä opettajat kokivat oppineensa yhteisopetuksen aikana?
2014
Tämä tutkimus käsittelee yhteisopetuksen opettajille tarjoamia oppimismahdollisuuksia. Tutkimuskysymyksemme on: Mitä opettajat kokivat oppineensa yhteisopetuksen aikana? Opettajat kokevat oppilaiden yksilöllisten tarpeiden huomioonottamisen suurissa opetusryhmissä yhä haastavammaksi, mikä lisää opettajan työn kuormittavuutta. Tämän myötä opettajat ovat yhä kiinnostuneempia vertaistuesta ja opettajien välisen yhteistyön kehittämisestä. Yhteisopetus voi olla vastaus myös erityisopetusta koskeviin lakimuu-toksiin sekä inkluusion tavoitteeseen, jonka mukaan kaikkien oppilaiden tulisi saada opiskella samassa luokassa. Tutkimuksemme avulla pyrimme esittämään, miten yhteisopetus voi edesauttaa ope…

Beta Decay of68–74Niand Level Structure of Neutron-Rich Cu Isotopes
1998
The isotopes ${}^{68--74}\mathrm{Ni}$, of interest both for nuclear physics and astrophysics, have been produced in proton-induced fission of ${}^{238}\mathrm{U}$ and ionized in a laser ion guide coupled to an on-line mass separator. Their $\ensuremath{\beta}$ decay was studied by means of $\ensuremath{\beta}$- $\ensuremath{\gamma}$ and $\ensuremath{\gamma}$- $\ensuremath{\gamma}$ spectroscopy. Half-lives have been determined and production cross sections extracted. A partial level scheme is presented for ${}^{73}\mathrm{Cu}$ and additional levels for ${}^{71}\mathrm{Cu}$, providing evidence for a sharply lowered position of the $\ensuremath{\pi}{1f}_{5/2}$ orbital as occupancy of the $\ens…
