Scientific Opinion on an application by Syngenta (EFSA-GMO-DE-2009-66) for placing on the market of herbicide tolerant and insect resistant maize Bt1…
2015
Question number: EFSA-Q-2009-00444 on request from Competent Authority of Germany; The EFSA GMO Panel previously assessed the four single events combined to produce a four-event stack maize Bt11 × MIR162 × MIR604 × GA21 and did not identify safety concerns. In this opinion, the EFSA GMO Panel assesses the four-event stack maize and all its subcombinations independently of their origin. No new data on the single events, leading to modification of the original conclusions on their safety, were identified. The molecular, agronomic, phenotypic and compositional data on the four-event stack maize did not give rise to safety concerns and there is no reason to expect interactions between the singl…
Virus-nucleus interactions in late herpesvirus infection
2017
Herpes simplex virus 1 (HSV-1) on alfaherpesviruksiin kuuluva vaipallinen, kaksijuosteista DNA:ta sisältävä virus. Kosketus- ja pisaratartuntana herkästi leviävä HSV-1 on maailmanlaajuisesti huomattava taudinaiheuttaja, sillä virusta kantaa arviolta 67 % väestöstä. Tartunta on elinikäinen. Latentissa vaiheessa HSV-1:n genomi säilyy aistihermojen hermosolmukkeissa. Viruksen aktivoituminen lyyttiseen lisääntymiskiertoon oireilee tyypillisesti rakkuloina kasvojen iholla ja limakalvoilla. HSV-1:n genomin replikoituminen ja uusien viruskapsidien muodostuminen tapahtuvat isäntäsolun tumassa, jossa viruksen rakentumisalue laajenee infektion edetessä. Samalla isäntäsolun kromatiini tiivistyy ja pak…
Littoral energy pathways in highly humic boreal lakes
2017
Littoral zones in lakes are among the most productive habitats in the world, but have been seriously understudied, as most limnological studies have concerned only pelagic habitats. The likely importance of littoral zones in clear lakes is widely acknowledged, but in contrast their role in dystrophic humic lakes has generally been assumed to be minor. In this thesis, littoral importance in whole-lake metabolism was studied in small and highly humic lakes in Southern Finland, where Lake Mekkojärvi was the principal study lake. Primary production (PP) measurements revealed that littoral periphyton, growing on surrounding aquatic vegetation, can dominate the whole-lake PP, and the highly autot…
Pārrobežu ūdens resursu apsaimniekošana Dienvidāfrikas attīstības kopienas upju baseinu ietvaros
2021
Pārrobežu ūdens apsaimniekošana paredz sarežģītu starp disciplīnu problēmu pastāvēšanu piekrastes valstīm. Ilgtspējīga ūdens pārvalde aptver politiskos, ekonomiskos, sociālos un vides aspektus. Lielāka apzināšanās par nenovēršamajām klimata izmaiņu ietekmēm liek jautāt, vai upju baseinu izmaiņas var pastiprināt potenciālas nesaskaņas pār ūdeni. Starptautiskais ūdens attiecību diskurss apgalvo, ka līguma un institucionālu mehānismu esamība spēj absorbēt ūdens mainīgumu, kas, turpretī, mazinātu nesaskaņu iespējamību. ”Hidro-hegemonija” izskaidro kā vienkārša līguma pastāvēšana negarantē miermīlīgas piekrastes valstu attiecības, tā saskata konflikta un sadarbības līdzāspastāvēšanu. Maģistra da…
Shape coexistence in neutron-deficient Hg isotopes studied via lifetime measurements in Hg-184,Hg-186 and two-state mixing calculations
2014
Abstract: The neutron-deficient mercury isotopes, 184 , 186 Hg, were studied with the recoil distance Doppler-shift method using the Gammasphere array and the K ̈ oln plunger device. The differential decay curve method was employed to determine the lifetimes of the yrast states in 184 , 186 Hg. An improvement on previously measured values of yrast states up to 8 + is presented as well as first values for the 9 3 state in 184 Hg and 10 + state in 186 Hg. B ( E 2) values are calculated and compared to a two-state mixing model which utilizes the variable moment of inertia model, allowing for extraction of spin-dependent mixing strengths and amplitudes. peerReviewed

IPMWORKS, a European network of pionneer farmers engaged to demonstrate cost-effective IPM-based strategies with low pesticide use
2022
Integrated Pest Management (IPM) is based on a diversity of pest management measures(prevention, non-chemical control, best practices for optimizing pesticide efficiency, etc.).These are combined at the farm level to enable reduced reliance on pesticides, and thereforea decrease in the exposure of the environment and people to pesticides. Rare pioneer farmersthroughout Europe are testing such IPM strategies and are succeeding in achieving goodoutcomes with low pesticide inputs. However the majority of European farmers still relyheavily on pesticides, with major environmental and societal impacts, because most of themhave not adopted a comprehensive, farm-level and holistic IPM strategy so f…
Bērna holistiskā aprūpe observācijas nodaļā
2017
Bakalaura darba tēma – Bērna holistiskā aprūpe observācijas nodaļā. Tēmas aktualitāti nosaka Slimību Profilakses un Kontroles centra dati, Latvijā 2013.gadā tika stacionēti 59378 bērni. Nonākot observācijas nodaļā, pacienta aprūpi uzsāk māsa. Bērni ar dažādam saslimšanām observācijās nodaļā ir neaizsargātā stāvoklī, atkarīgi no aprūpes māsam, kuras zin un saprot bērna vajadzības. Darba mērķis ir izpētīt holistiskās aprūpes pamatprincipus māsas darbā observācijās nodaļā. Pētniecības uzdevumi ir: 1. veikt zinātniskās literatūras un pētījumu analīzi par holistisko aprūpi; 2. izstrādāt pētījuma instrumentu – intervija; 3. veikt pētījumu; 4. apkopot un analizēt iegūtos rezultātus; 5. veikt secin…
Determination of pesticide residues in honey bees, pollen and beeswax: assessing pesticide hazard in spanish apiaries
2020
Pollinator decline is an emerging worldwide problem with serious repercussions on agriculture and environment. Around one third of human food relies on insect pollination, and most of the flowering plants need pollinators to survive. Honey bee is the main pollinator in environments where anthropogenic pressure has reduced the number of native pollinators, like urban, rural and agricultural areas. The main cause of beekeeping crisis is parasite Varroa destructor and secondary infections associated with the mite. Pesticide contamination and nutritional deficiencies, combined with the parasite, can act synergistically and reduce survival of bee colonies. Honey bees patrol extensive areas when …
