Veselīga uztura „šķīvja principa” radītās izmaiņas ķermeņa antropometriskajos un asins plazmas bioķīmiskajos parametros atkarībā no diētas veida.
2021
Veselīga uztura “šķīvja princips” ir vienkāršs pedagoģisks princips, kā apgūt sabalansēta uztura principus. Lai gan “šķīvja princips” ir plaši zināms un pielietots, joprojām pastāv dažādi veidi, kā attēlo produktu grupas un makrovielu kategorijas uz šķīvja. Pētījumi attiecībā uz zinātnisko pamatojumu “šķīvja principa” piemērotībai uzturā un atbilstību uztura rekomendācijās noteikto makro un mikrovielu daudzumam nav pieejami. Šī pētījuma eksperimentālais dizains izstrādāts tā, lai salīdzinātu dažādu hronisko slimību attīstības riska marķieru – antropometrisko un plazmas bioķīmisko parametru – izmaiņas sešu nedēļu garumā atkarībā no ievērotā diētas veida (visēdāju ar mazāk dzīvnieku izcelsmes…
Iedzīvotāju zināšanas par žultsakmeņu slimības attīstību veicinošajiem faktoriem un profilaksi
2021
Visā pasaulē, tajā skaitā arī Latvijā, viena no biežākajām ķirurģiskajām saslimšanām, kam nepieciešama operatīva ārstēšana, ir žultsakmeņu slimība (ŽAS) jeb holelitāze. Tās izplatība pieaug līdz ar iedzīvotāju vecumu un mūsdienu dzīvesveida paradumiem, tādiem kā, nesabalansēts, neregulārs uzturs un mazkustīgs dzīvesveids. Šis bakalaura darbs tika izveidots ar mērķi - noskaidrot iedzīvotāju zināšanas par žultsakmeņu slimības attīstību veicinošajiem faktoriem un profilaksi. Pirms pētījuma veikšanas, lai pārliecinātos par anketas jautājumu saprotamību, tika veikts pilotpētījums, aptaujājot desmit respondentus. Analizējot, sniegtās atbildes, tika secināts, ka ir nepieciešams veikt labojumus 4. …

Late Jurassic (Kimmeridgian–Tithonian) stable isotopes (δ18O, δ13C) and Mg/Ca ratios: New palaeoclimate data from Helmsdale, northeast Scotland
2010
Abstract The data presented here provide the first detailed stable isotope ( δ 18 O, δ 13 C) and geochemical (Mg/Ca) investigation of Kimmeridgian–Tithonian belemnites from the Helmsdale Coast, Scotland, UK. Oxygen and carbon stable isotope values from well preserved specimens range from − 2.8 to + 0.3‰ and from − 2.3 to + 2.8‰ respectively. The oxygen isotope data are consistent with palaeotemperatures of up to 24 °C in the Early Kimmeridgian cymodoce Zone and down to 11 °C in the Mid Tithonian rotunda–fittoni Zones. These estimates are strongly supported by the Mg/Ca data, which also indicate a cooling episode (and very similar palaeotemperatures, 11–22 °C) at this time. The cooling event…
Unraveling environmental histories from skeletal diaries — Advances in sclerochronology
2013
High-resolution proxy archives from aquatic settings are essential to better understand processes and mechanisms of global change. During the last decade, it has become increasingly evident that calcified tissues of bivalve mollusks and cold-water corals, in particular, can significantly increase our knowledge of seasonal to multi-decadal paleoclimate and paleoenvironmental variability in the extratropical oceans and coastal marine settings. Daily, tidal, fortnightly and annual growth patterns of periodically formed skeletal hard parts provide a means to place the proxy record in a precise temporal context. Their extreme longevity coupled with the running similarity between growth increment…
Carbon cycle and sea-water palaeotemperature evolution at the Middle-Late Jurassic transition, eastern Paris Basin (France).
2014
14 pages; International audience; A very high-resolution carbon and oxygen stable isotope analysis (bulk-carbonate) of a biostratigraphically well-constrained Callovian-Oxfordian series is provided here for the first time. The homogeneity of the clayey series and the weak diagenetic alteration allow the isotopic signal variations to be considered as primary in origin. A prominent and brief negative excursion in the δ13C curve (−2‰), occurring at the start of the Middle Callovian (Jason Zone - Obductum Subzone) and correlated regionally, suggests a possible methane release. The increasing δ13C values thereafter up to the Early Oxfordian, concomitant with a warming episode, highlight the buri…
Search for scalar leptoquarks in pp collisions at $\sqrt{s}$=13 TeV with the ATLAS experiment
2016
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √s = 13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb-1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons (muons) and two or more jets. The observed event yield in each channel is consistent with Standard Model background expectations. The observed (expected) lower limits on the leptoquark mass at 95% confidence level are 1100 and 1050 GeV (1160 and 1040 GeV) for first and second generation leptoqua…
Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment
2018
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ℓ+ℓ−c¯c is studied. A data set with an integrated luminosity of 36.1 fb−1 of pp collisions at √s=13TeV recorded by the ATLAS experiment at the LHC is used. The H→c¯c signature is identified using charm-tagging algorithms. The observed (expected) upper limit on σ(pp→ZH)×B(H→c¯c) is 2.7 (3.9+2.1−1.1) pb at the 95% confidence level for a Higgs boson mass of 125 GeV, while the standard model value is 26 fb.
