Interaktīva, informatīva tūrisma tīmekļa vietne
2015
Šī kvalifikācijas darba mērķis ir izstrādāt tūrisma tīmekļa vietni. Sistēmas mērķis ir ļaut lietotājiem aplūkot informāciju par vietējiem tūrisma objektiem un pieejamām ekskursijām Līgatnē, kā arī dot iespēju pieteikties ekskursijām aizpildot veidlapu vietnē. Šajā vietnē arī ir pieejama attēlu galerija un jaunumu lapa. Administrators var vietnei pievienot tūrisma objektus, ekskursijas/piedāvājumus, attēlus un jaunumus izmantojot administrācijas sadaļu.
RESTful tīmekļa servisa izstrāde apdrošināšanas uzņēmumam
2017
Izstrādātā tīmekļa servisa galvenā funkcija ir pieņemt no citas sistēmas augšupielādētos attēlus, saglabāt tos datņu krātuvē, un nodot trešajai pusei attēlā redzamā objekta atpazīšanai. Lietotne ir daļa no uzņēmuma KASKO informācijas sistēmas, tās uzdevums ir būt par mediatoru starp citām uzņēmuma sistēmām un trešo pušu sistēmām. Pakalpojuma izstrādē izmantota programmēšanas valoda PHP 7.1 un ietvars Laravel 5.4. Dati tiek glabāti MySQL savietojamā datu bāzē. Sistēma izstrādāta praktizējot DDD principu.
Precision measurement of D meson mass differences
2013
Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D-0 mass. The measurements are based on a dataset corresponding to an integrated luminosity of 1.0 fb(-1) collected in pp collisions at 7 TeV. Using the decay D-0 -> K+K-K-pi(+), the D-0 mass is measured to be M(D-0) = 1864.75 +/- 0.15 (stat) +/- 0.11 (syst) MeV/c(2). The mass differences M(D+) - M(D-0) = 4.76 +/- 0.12 (stat) +/- 0.07 (syst) MeV/c(2), M(D-s(+)) - M(D+) = 98.68 +/- 0.03 (stat) +/- 0.04 (syst) MeV/c(2) are measured using the D-0 -> K+K-pi(+)pi(-) and D-(s)(+) -> K+K-pi(+) modes.
Probing a Polar Cluster in the Retinal Binding Pocket of Bacteriorhodopsin by a Chemical Design Approach
2012
Bacteriorhodopsin has a polar cluster of amino acids surrounding the retinal molecule, which is responsible for light harvesting to fuel proton pumping. From our previous studies, we have shown that threonine 90 is the pivotal amino acid in this polar cluster, both functionally and structurally. In an attempt to perform a phenotype rescue, we have chemically designed a retinal analogue molecule to compensate the drastic effects of the T90A mutation in bacteriorhodopsin. This analogue substitutes the methyl group at position C(13) of the retinal hydrocarbon chain by and ethyl group (20-methyl retinal). We have analyzed the effect of reconstituting the wild-type and the T90A mutant apoprotein…
Consumer Acceptance and Quality Parameters of the Commercial Olive Oils Manufactured with Cultivars Grown in Galicia (NW Spain)
2020
Mansa and Brava are olive autochthonous cultivars from Galicia, a new olive-growing zone from NW Spanish, from which high-quality extra virgin olive oils (EVOOs) are obtained. The oils obtained as by co-crushing Mansa and Brava olives in different proportions as by blending with others olives cultivars have different composition that influence in their sensory quality. The consumer acceptance of commercial oils elaborated with Local Galician cultivars was evaluated and a quality-mapping of olive oils was created. It was found that the both Local oils had good physical-chemical quality parameters. From sensory analysis viewpoint, Local-MB oils presented the highest intensity values for color…
Nutrition Knowledge Is Associated with Energy Availability and Carbohydrate Intake in Young Female Cross-Country Skiers
2021
The aim of this study was to provide information on energy availability (EA), macronutrient intake, nutritional periodization practices, and nutrition knowledge in young female cross-country skiers. A total of 19 skiers filled in weighted food and training logs before and during a training camp. Nutrition knowledge was assessed via a validated questionnaire. EA was optimal in 11% of athletes at home (mean 33.7 ± 9.6 kcal·kgFFM−1·d−1) and in 42% at camp (mean 40.3 ± 17.3 kcal·kgFFM−1·d−1). Most athletes (74%) failed to meet recommendations for carbohydrate intake at home (mean 5.0 ± 1.2 g·kg−1·d−1) and 63% failed to do so at camp (mean 7.1 ± 1.6 g·kg−1·d−1). The lower threshold of the pre-ex…
Knowledge, attitudes and risk of HIV, HBV and HCV infections in hairdressers of Palermo city (South Italy)
2009
Background: The hairdressing trade may potentially expose its practitioners and their customers to blood-borne infections. Methods: Knowledge, attitudes and behaviours towards occupational risk of HIV, HBV and HCV infections were evaluated in a cross-sectional survey, conducted during spring 2008, in 105 out of 112 randomly selected hairdressers of Palermo. Participants were queried by answering to an anonymous questionnaire. Results: Most of hairdressers (93.3%) knew that HIV and hepatitis are transmitted through parenteral route and could also be transmitted by razors. The availability of gloves was inadequate, up to 30% of the participants never used them and up to 50% usually reused the…
Exposure to patulin from consumption of apple-based products.
2007
Patulin is a mycotoxin produced by species of Penicillium, Aspergillus and Byssochylamys. Several Scientific Committees classify patulin as mutagenic, embryotoxic and immunotoxic. It has been found as a natural contaminant of processed apple products and its presence may be indicative of the quality of fruit used in production. In this work, a method for the analysis of patulin is described, based on a simple liquid-liquid extraction with acetonitrile; patulin is analyzed using liquid chromatography with UV detection. Patulin identity was confirmed by GC-MS after its reaction with N-methyl-N-(trimethylsilyl)trifluoroacetamide. Fifty-three apple-containing products were analyzed and patulin …
Metabolism of chlorobenzene and hexachlorobenzene by the zebra fish, Brachydanio rerio.
1989
It is now becoming evident that in many cases metabolites have a greater toxic potential than the parent xenobiotic exposed. For this reason, the knowledge of biotransformation pathways of xenobiotics plays a substantial role in environmental monitoring programs. The zebra fish (Brachydanio rerio, Hamilton-Buchanan) has received increased attention as a model species for freshwater fish in environmental surveillance programs to evaluate potential health and impacts of anthropogenic chemicals. The metabolism of phenol and various substituted phenols in zebra fish has recently been studied. The purpose of the present study was to examine the metabolism of chlorobenzene and hexachlorobenzene (…
LA OCUPACIÓN SOLUTRENSE DEL ABRIGO DE LA BOJA (MULA, MURCIA, ESPAÑA)
2013
El relleno pleistoceno del Abrigo de la Boja (ADB) empieza con un nivel adscrito al Magdaleniense superior, seguido de un potente paquete con ocupación difusa bajo el cual se desarrolla una secuencia depositada durante el último máximo glacial caracterizada por una serie de estructuras de combustión, de tipo hogar plano/amorfo (open hearth), existiendo también hogares de cubeta. Destaca un hogar enlosado, completo y muy bien conservado, excavado en 2012 y adscrito provisionalmente al Solutreogravetiense. Los niveles solutrenses subyacentes son ricos en elementos de adorno, entre los cuales conchas perforadas de Littorina obtusata y Smaragdia viridis; su industria lítica incluye raspadores, …
