Microbiological investigation of Raphanus sativus L. grown hydroponically in nutrient solutions contaminated with spoilage and pathogenic bacteria
2012
Abstract The survival of eight undesired (spoilage/pathogenic) food related bacteria (Citrobacter freundii PSS60, Enterobacter spp. PSS11, Escherichia coli PSS2, Klebsiella oxytoca PSS82, Serratia grimesii PSS72, Pseudomonas putida PSS21, Stenotrophomonas maltophilia PSS52 and Listeria monocytogenes ATCC 19114T) was investigated in mineral nutrient solution (MNS) during the crop cycle of radishes (Raphanus sativus L.) cultivated in hydroponics in a greenhouse. MNSs were microbiologically analyzed weekly by plate count. The evolution of the pure cultures was also evaluated in sterile MNS in test tubes. The inoculated trials contained an initial total mesophilic count (TMC) ranging between 6.…
Dažādu ielabošanas līdzekļu izmantošanas ietekme uz elementu saturu jaunu hibrīdalkšņu koksnē
2022
Dažādu ielabošanas līdzekļu izmantošanas ietekme uz elementu saturu jaunu hibrīdalkšņu koksnē. Isajeva A., zinātniskais vadītājs Mg.Chem. Māris Bērtiņš, Bakalaura darbs, 32 lappuses, 10 attēli, 7 tabulas un 26 literatūras avoti. Latviešu valodā. Bakalaura darbā tika noteikts elementu plūsma hibrīdalkšņa koksnē, kuru koki bija apstrādāti ar dažādiem ielabošanas līdzekļiem, izmantojot ICP-MS metodi. Darbā veikta hibrīdalkšņa paraugu sagatavošana ar slapjo mineralizāciju slēgtos traukos. Tika analizēta elementu uzkrāšanas un sadalījums koksnē, atkarība no ielabošanas līdzekļiem.
Archaeometric evidence attesting production of indigenous archaic pottery at Monte Polizzo (Western Sicily)
2012
Excavations at the proto-urban indigenous settlement of Monte Polizzo (western Sicily) have not yielded so far any evidence of in-situ ceramic production (i.e. kiln structures). However several archaeological concerns put forward to consider it as a likely production centre of pottery during the Archaic age. In this paper a first attempt to check the compositional correspondence between ceramic fabrics and local clay sources has been made. A comprehensive archaeometric investigation of native pottery, mainly composed of matte-painted table ware dated from the 7th to the 4th century BC, recovered from the Acropolis of Monte Polizzo has allowed the identification of five distinct ‘Paste Compo…
FLUID AND ELECTROLYTE SUPPLEMENTATION IN ATHLETES AND FITNESS PEOPLE. A REVIEW
2009
Il presente lavoro pone l’accento sull'importanza di una corretta idratazione sia per gli atleti sia per i sedentari. E’ infatti noto che l'acqua e i componenti in essa disciolti sono di fondamentale importanza per mantenere inalterate le principali funzioni del nostro organismo. Sono stati analizzati in particolare i sali minerali contenuti nell’acqua e nelle bevande utilizzate per la loro integrazione. E’ infatti invalso l'uso e l'abuso di integratori salini per gli atleti sulla cui utilità sono presenti in letteratura diversi contributi. Gli AA hanno anche approfondito il tema della sudorazione e le situazioni in cui aumentano le perdite di fluidi corporei cercando di capire come atleti …
Structural approach of social representation: Application to the concept of wine minerality in experts and consumers
2015
© 2015 Elsevier Ltd. In recent years the sensory evaluation field has been moving from the traditional sensory descriptive methodologies towards consumer based methodologies. Sensory descriptions are not confined to sensory evaluation. In everyday life, people use also descriptions to communicate about products sensory properties. The theory of social representation offers a new approach for studying the meaning of the terminology used in these everyday life descriptions. One implication of this theory is that meaning is created through a system of social negotiations rather than being a fixed and finite code. The goal of the present study was to understand the meaning of the concept of win…
In-situ Mössbauer Spectroscopy with MIMOS II at Rio Tinto, Spain
2010
The Rio Tinto, located in southwest Spain, exhibits a nearly constant, acidic pHvalue along its course. Due to the formation of sulfate minerals, Rio Tinto is considered a potential analogue site for sulfate-rich regions on Mars, in particular at the landing site of the Mars Exploration Rover Opportunity, where the ferric sulfate mineral jarosite was identified with Opportunity's Mössbauer spectrometer. Primary and secondary mineralogy was investigated in situ with portable Raman and Mössbauer spectrometers at four different Rio Tinto sampling sites. The two techniques analyse different sample portions due to their specific field of view and sampling depth and provide complementar…

Vienota dabas tūrisma maršruta izveide Ķemeros
2020
Bakalaura darba ietvaros ir mēģināts izveidot vienota tūrisma maršruta karti Jūrmalas pilsētas Ķemeru apkaimē, papildus vēršot uzmanību uz teritorijas minerālūdens resursiem un to kvalitāti. Par pamatu šim pētījumam kalpo autores īstenotie agrākie darbi- bakalaura darba projekts „Jūrmalas minerālūdens un termālo ūdens resursu pārvaldība” un lietišķo studiju ietvaros veiktais pārskats „Ķemeru un Jaunķemeru apkaimē esošo urbumu apsaimniekošanas iespējas”. Ar iepriekš minētā pārskata rezultātiem autore ir iepazīstinājusi plašāku auditoriju Latvijas Universitātes 78. starptautiskajā zinātniskajā konferencē.
Le anfore fenicio-puniche prodotte nel Mediterraneo occidentale: caratteristiche petrografiche degli impasti siciliani e spagnoli.
2009
The aim of this paper is to provide well-stated petrographic reference groups for the recognition of several Sicilian and Spanish Phoenician-Punic production centres in order to facilitate an instrument of further objective support for amphorae provenance. This instrument is based on the crosschecking between data provided by typological studies and the thinsection analysis of amphorae fabrics. It is worth noting that this is only a first step within the framework of a larger research project focused in the creation of an Atlas of Phoenician and Punic Amphorae in the Western Mediterranean including both archaeological and petrographic data. In this context a systematical work on the known p…
La produzione di ceramica da mensa a Solunto: un esempio di continuità tecnologica dallʼetà arcaica a quella ellenistico-romana.
2009
Solunto is one of the most important Phoenician-Punic colonies of north-western Sicily. Archaeometric researches carried out in the last years ascertained a local production of transport amphorae during Archaic and Classic age (7th-5th century B.C.) through mineralogical, petrographical and chemical analysis of ceramic samples, kiln refuses and local raw materials (clays and alluvial sands). In connection with these earliest works, the present paper was focused on some specific forms of fine-tempered table ware of Archaic age and/or Classic-Hellenistic age. This pottery has been recurrently brought to light in Solunto and it is furthermore suspected to be, at least to some extent, a local r…
