Baltmāla pīpes Ventspils un Kuldīgas arheoloģiskajā materiālā

2017

Baltmāla pīpe ir viens no visbiežāk atrastajiem priekšmetiem jaunāko vēsturisko laiku arheoloģisko izrakumu vietās. Arī Latvijas teritorijā baltmāla pīpju atradumu skaits ir salīdzinoši liels, kas tad arī liek pievērst uzmanību to pētniecībai. Šo priekšmetu pētniecība Latvijā ir sākuma stadijā, un bieži vien praksē tai netiek pievērsts pietiekami daudz uzmanības. Bakalaura darbā apkopotas baltmāla pīpes, kas atrastas arheoloģisko izrakumu un uzraudzības darbu laikā Ventspilī un Kuldīgā. Pētījuma mērķis ir analizēt Ventspilī un Kuldīgā atrastās baltmāla pīpes (to fragmentus), vadoties pēc analoģijām samērā plaši pētītajā Eiropas materiālā par baltmāla pīpēm. Pētījuma rezultātā noskaidrota in…

Rīgas iedzīvotāju veselībpratība

2019

Šī darba tēma ir “Rīgas iedzīvotāju veselībpratība”. Darba mērķis ir noskaidrot Rīgas iedzīvotāju veselībpratības līmeni un tā saistību ar izglītības līmeni, vērtējumu par savu veselības stāvokli un profilaktisku rīcību veikšanu. Lai sasniegtu darba mērķi, darbā tiek izmantota veselībpratības teorija. Balstoties uz iepriekš veiktajiem pētījumiem, tiek izvirzītas hipotēzes un tiek veikts empīriskais pētījums – interneta aptauja. Lai noskaidrotu Rīgas iedzīvotāju veselībpratības līmeni, aptaujas anketā iekļauti Eiropas veselībpratības pētījuma saīsinātā 16 jautājumu skala, ko izveidojis Vīnes universitātes Socioloģijas institūta profesors, kā arī Austrijas sabiedrības veselības institūta dire…

Determination of pesticides and veterinary drug residues in food by liquid chromatography-mass spectrometry: A review

2015

Monitoring of pesticides and veterinary drug residues is required to enforce legislation and guarantee food safety. Liquid chromatography-mass spectrometry (LC-MS) is the prevailing technique for assessing both types of residues because LC offers a versatile and universal separation mechanism suitable for non-gas chromatography (GC) amenable and the majority of GC-amenable compounds. This characteristic becomes more relevant when LC is coupled to MS because the high sensitivity and specificity of the detector allows to apply generic sample preparation procedures, which simultaneously extract a wide variety of residues with different physico-chemical properties. Determination of metabolites …

Toxicity of several d-endotoxins of Bacillus thuringiensis against Helicoverpa armigera (Lepidoptera: Noctuidae) from Spain

2005

Abstract Toxicity and larval growth inhibition of 11 insecticidal proteins of Bacillus thuringiensis were evaluated against neonate larvae of Helicoverpa armigera, a major pest of important crops in Spain and other countries, by a whole-diet contamination method. The most active toxins were Cry1Ac4 and Cry2Aa1, with LC50 values of 3.5 and 6.3 μg/ml, respectively. At the concentrations tested, Cry1Ac4, Cry2Aa1, Cry9Ca, Cry1Fa1, Cry1Ab3, Cry2Ab2, Cry1Da, and Cry1Ja1, produced a significant growth inhibition, whereas Cry1Aa3, Cry1Ca2, and Cry1Ea had no effect.

Esterase isoenzymes and insecticide resistance in Frankliniella occidentalis populations from the south-east region of Spain.

2008

BACKGROUND:Frankliniella occidentalis (Pergande) is among the most important crop pests in the south-east region of Spain; its increasing resistance to insecticides constitutes a serious problem, and understanding the mechanisms involved is therefore of great interest. To this end, F. occidentalis populations, collected from the field at different locations in south-east Spain, were studied in terms of total esterase activity and esterase isoenzyme pattern. RESULTS: Individual thrips extracts were analysed by native polyacrylamide gel electrophoresis (PAGE) and stained for esterase activity with the model substrate α-naphthyl acetate. Significant correlations were found between resistance t…

Short communication: casein haplotype variability in sicilian dairy goat breeds.

2008

In the Mediterranean region, goat milk production is an important economic activity. In the present study, 4 casein genes were genotyped in 5 Sicilian goat breeds to 1) identify casein haplotypes present in the Argentata dell'Etna, Girgentana, Messinese, Derivata di Siria, and Maltese goat breeds; and 2) describe the structure of the Sicilian goat breeds based on casein haplotypes and allele frequencies. In a sample of 540 dairy goats, 67 different haplotypes with frequency >or=0.01 and 27 with frequency >or=0.03 were observed. The most common CSN1S1-CSN2-CSN1S2-CSN3 haplotype for Derivata di Siria and Maltese was FCFB (0.17 and 0.22, respectively), whereas for Argentata dell'Etna, Girgenta…

Performance of the C-MAC video laryngoscope in patients after a limited glottic view using Macintosh laryngoscopy

2011

We applied the C-MAC videolaryngoscope in 52 consecutive patients who were found to have an unexpected Cormack and Lehane grade-3 (n = 49) and grade-4 (n = 3) laryngeal view with the Macintosh laryngoscope. The glottic view improved in 49 (94%) patients using the C-MAC. Tracheal intubation was successful in 49 of 52 patients (94%). In one patient, tracheal intubation failed using the C-MAC despite the presence of a Cormack and Lehane grade-2. These results suggest that the C-MAC videolaryngoscope has a role as a rescue device in cases of an initially difficult laryngeal view.
