Exploring the mechanisms by which reindeer droppings induce fen peat methane production
2021
Abstract Peatlands, especially fens, are known to emit methane. Reindeer (Rangifer tarandus) use mires mainly as spring and summer pastures. In this work we observed that adding reindeer droppings to fen peat increased the potential methane production by 40%. This became apparent when droppings originating from reindeer kept in pen or pasture in winter were added to methanogenic fen peat samples. The droppings introduced Methanobacteriaceae (Methanobrevibacter; > 90% of the mcrA MiSeq reads) to the peat, which was originally populated by Methanosarcinaceae, Methanosaetaceae, Methanoregulaceae, Methanobacteriaceae, Methanomassiliicoccaceae, Methanocellaceae and Methanomicrobiaceae. The origi…
Izziņas prasmju sekmēšana rīta pastaigas laikā pirmsskolas izglītības 3.posmā
2022
Darba autore: Baiba Alberga Darba tēma: Izziņas prasmju sekmēšana rīta pastaigas laikā pirmsskolas izglītības 3.posmā. Pētījuma mērķis: izpētīt pirmsskolas izglītības 3.vecuma posma bērnu izziņas prasmju sekmēšanu rīta pastaigas laikā. Darba teorētiskajā daļā tika analizēta un pētīta informācija par pirmsskolas izglītību un tās mērķiem attiecīgajā vecuma posmā, izziņas jeb kognitīvajiem procesiem, rīta pastaigu kā organizācija formu pirmsskolā, nodarbību organizēšanu āra vidē un rotaļu nozīmi pirmsskolā. Darbā ir aprakstīti rīta pastaigas kā organizācijas formas pirmsskolā pieci galvenie uzdevumi – darbs dabā, kustību rotaļa / aktivitāte, vērojums, eksperiments un brīvā aktivitāte. Katrs no…
Pasteļtehnikas paņēmienu apguve vizuālās mākslas stundās 8. klasē
2016
Diplomdarba tēma ir „Pasteļtehnikas paņēmienu apguve vizuālās mākslas stundās 8. klasē." Diplomdarba mērķis: balstoties uz teorijas izpēti, izveidot un aprobēt uzdevumu kopu, kas 8. klases skolēnus vizuālās mākslas stundās iepazīstina ar pasteļtehnikas pamatiem un tās raksturīgākajiem izteiksmes līdzekļiem. Darbs sastāv no teorētiskās un praktiskās daļas. Teorētiskajā daļā ir veikts ieskats pasteļtehnikas vēsturē un tās zināmākajos mākslas pārstāvjos, pasteļa raksturošanā un tā uzklāšanas veidu apkopošanā. Praktiskajā daļā ir izskatītas pusaudžu vecumposma īpatnības un pedagoģiskās izmēģinājuma bāzes raksturojums, pēc kā vēlāk ir veidota uzdevumu kopa. Uzdevumu kopa praktiskajā darbā atklāj…
Pozitīvas saskarsmes veicināšana pamatskolas skolēniem ar vidēji smagiem garīgās attīstības traucējumiem un agresiju
2020
Darba autore: Ieva Romančuka Darba nosaukums: Pozitīvas saskarsmes veicināšana pamatskolas skolēniem ar vidēji smagiem garīgās attīstības traucējumiem un agresiju. Darba aktualitāte: Speciālās izglītības skolotājam, strādājot ar skolēniem, kuriem ir vidēji smagi garīgās attīstības traucējumi, ikdienā bieži ir jāsaskaras ar agresiju. Agresija ietekmē visu iesaistīto emocionālo stāvokli un pārtrauc mācību darbību. Tāpēc pedagogam nepieciešamas zināšanas un prasmes kā efektīvi pārvaldīt izaicinošu uzvedību, saglabājot pozitīvu saskarsmi ar skolēnu. Darba mērķis: Izvēlēties teorijā balstītu metodi vai paņēmienu, lai veicinātu pozitīvu saskarsmi ar skolēniem, kuriem ir vidēji smagi garīgās attīs…
Effectiveness of hexavalent vaccines against invasive Haemophilus influenzae type b disease: Germany's experience after 5 years of licensure
2007
Summary Vaccine effectiveness (VE) was determined with a case-cohort approach using Cox regression. Cases with confirmed systemic Hib infections in children born from 1 August 2000 to 31 December 2004 were ascertained through two independent nationwide active surveillance systems. A representative cohort of 1303 children born in the same time frame was randomly sampled in a nationwide immunisation survey. Thirty cases were eligible for VE calculation; 19 were unvaccinated and 11 vaccinated with hexavalent vaccines. VE was 68.4% (95% CI: 19.0–87.6) for incomplete primary series and 90.4% (95% CI: 70.6–96.8) for the full primary series. For full immunisation VE was 100.0% (95% CI: 52.7–100.0)…
Primary lateral sclerosis and hereditary spastic paraplegia in sporadic patients. An important distinction in descriptive studies.
2016
Abstract Differentiating between primary lateral sclerosis and apparently sporadic hereditary spastic paraplegia patients is an important but difficult issue in transversal studies. Consequently, these patients have been indistinctly classified as primary lateral sclerosis or sporadic HSP in different publications, further contributing to the confusion between both diseases. In our opinion, Schule et al have not reliably excluded PLS in their cohort of simplex HSP, what could affect their reported results. We think that a clearer distinction should be made between both diseases and we propose new definitions and criteria to facilitate this differentiation. This article is protected by copyr…
Evaluation of a fluorosis prevention educational program: A randomized field trial.
2017
Background A 2-group randomized field trial was conducted to evaluate the impact of a fluorosis educational preventive program in mother´s knowledge and practices, and on the urine fluoride concentration of their preschool children. Material and Methods A group of 139 mother-child pairs participated in the study. Randomly, children were assigned to an intervention group, their mothers were participants of an educational program, or a control group (CG); including 69 and 70 child-mother pairs, respectively, the follow-up period was six months. Mother´s knowledge and practices were evaluated and children´s first urine sample was used to measure fluoride concentration at the beginning of the s…
Unravelling the modus operandi of phytosiderophores during zinc uptake in rice: the importance of geochemical gradients and accurate stability consta…
2020
Abstract Micronutrient deficiencies threaten global food production. Attempts to biofortify crops rely on a clear understanding of micronutrient uptake processes. Zinc deficiency in rice is a serious problem. One of the pathways proposed for the transfer of zinc from soils into rice plants involves deoxymugineic acid (DMA), a phytosiderophore. The idea that phytosiderophores play a wider role in nutrition of Poaceae beyond iron is well established. However, key mechanistic details of the DMA-assisted zinc uptake pathway in rice remain uncertain. In particular, questions surround the form in which zinc from DMA is taken up [i.e. as free aqueous Zn(II) or as Zn(II)–DMA complexes] and the role…
