ElvĂ©geztĂĽk a nĂ©gy fĹ‘bb hazai talajtani adatbázisban (Digitális Kreybig TalajinformáciĂłs Rendszer, GĂ©czy, ĂĽzemi genetikus, TIM) tárolt archĂv adatok konvertálhatĂłsági minĹ‘sĂtĂ©sĂ©t, az adatok harmonizált felhasználása Ă©rdekĂ©ben összesĂtettĂĽk Ă©s rendszereztĂĽk a tárolt informáciĂłkat, kialakĂtottunk egy olyan metaadat struktĂşrát, amely tartalmazza az egyes paramĂ©terek definĂciĂłját, mĂ©rtĂ©kegysĂ©gĂ©t, vagy klasszifikált paramĂ©ter esetĂ©n annak tematikus tartalmát. A kor nemzetközi standardjainak (FAO talajleĂrási ĂştmutatĂł, WRB) Ă©s a megĂşjĂtott hazai helyszĂni felvĂ©telezĂ©s Ă©s leĂrás mĂłdszertanának, illetve az osztályozás elemeinek megfeleltetĂ©sĂ©hez egyszerűsĂtett algoritmusok kerĂĽltek kidolgozásra. A vizsgált adatbázis struktĂşrákat alkalmassá tettĂĽk a származtatott adatok tárolására, kezelĂ©sĂ©re. LĂ©trehoztunk egy publikus on-line felĂĽletet (http://osiris.helion.hu/), melyen a felhasználĂłk nĂ©gy adatstruktĂşrához igazodva, a saját szelvĂ©nyadataik alapján megállapĂthatják, hogy azok mennyiben alkalmasak az egyszerűsĂtett algoritmusok segĂtsĂ©gĂ©vel törtĂ©nĹ‘ megfeleltetĂ©sre. A hazai talajtani adatbázisok nemzetközi Ă©s hazai harmonizáciĂłjának Ăşj megközelĂtĂ©sekĂ©nt teszteltĂĽk az AGROTOPO Ă©s a DKTIR Soil Core modell alkalmazási sĂ©májába valĂł konverziĂłját. A diagnosztikus kategĂłriák tĂ©rkĂ©pezĂ©sĂ©re indikátor krigelĂ©sen alapulĂł mĂłdszert dolgoztunk ki Ă©s teszteltĂĽnk le. Az eredmĂ©nyĂĽl kapott nem hagyományos, digitális talajtĂ©rkĂ©p az adott diagnosztikai elem elĹ‘fordulásának valĂłszĂnűsĂ©gĂ©t regionalizálja. | The screening, qualification and harmonization of the legacy data of the main Hungarian data bases (Kreybig Digital Soil Information System, GĂ©czy, field scale genetic maps, The Soil Information of the National Monitoring System – TIM) was completed and the data was organized into new structure. The metadata structure includes the definitions and dimensions of the parameters and the information contents of the of classification categories. Algorithms were developed to correlate soil data with international standards, such as the FAO guidelines for soil descriptions and the World Reference Base for soil resources. The completed database is able to store and process input data. A public online platform (http://osiris.helion.hu/) created that allows the users to upload and test the conversion options of their profile data with the algorithms. The AGROTOPO and the DKTIR Soil Core models were applied to test the harmonization and conversion of the data sets with international standards. Property and indicator maps were generated and tested based on krieging models. The conventional and digital results maps are providing information on the spatial distribution diagnostic elements
Monitoring by HPLC of chamomile flavonoids exposed to rat liver microsomal metabolism
Three major flavonoid chamomile components (quercetin, apigenin-7-O- glucoside and rutin) were subjected to oxidative metabolism by cytochrome P-450 of rat liver microsomal preparations. Changes over time in their respective concentrations were followed using reversed-phase HPLC with UV detection. No clean-up had to be applied as only the specific flavonoid had to be separated from the background components originating from the rat liver microsome. Neither the concentration of apigenin-7-O-glucoside nor that of the diglycoside rutin decreased during one hour of exposure to rat microsomal treatment. In contrast, the concentration of quercetin, a lipophilic aglycon, decreased. Our analytical HPLC results complement the in silico calculated lipophilicity (logP) of these compounds; the relatively high lipophilicity of quercetin appears to predispose it to oxidative metabolism in order to decrease its fat solubility. In contrast the much less lipophilic compounds apigenin-7-O-glucoside and rutin were resistant in vitro to microsomal treatment. © A.A. El Maghraby; Licensee Bentham Open
Validating Formal Semantics by Property-Based Cross-Testing
To describe the behaviour of programs in a programming language we can define a formal semantics for the language, and formalise it in a proof assistant. From this semantics we can derive the behaviour of each particular program in the language. But there remains the question of validating the formal semantics: have we got the formalisation right?
Our approach is to use property-based cross-testing of formal semantics, which is based on the combination of a number of existing approaches to validation. In particular, we give a concrete implementation of our ideas for a set of formalisations of Erlang and Core Erlang. We describe the adjustments that need to be made to execute these seman- tics, then we present and evaluate property-based testing in the context of cross-checking semantics, including random program generation and counterexample shrinking
Gondnoksági perekben tapasztalt visszásságok, a jogalkalmazás egységességének hiánya
Magyarország 2007-ben ratifikálta az ENSZ FogyatĂ©kossággal ÉlĹ‘ SzemĂ©lyek JogairĂłl szĂłlĂł EgyezmĂ©nyĂ©t (a továbbiakban: CRPD). 2014-tĹ‘l pedig az ebbĹ‘l következĹ‘ nemzetközi elvárásoknak Ă©s szakmai elveknek megfelelĹ‘en mĂłdosult a Polgári TörvĂ©nykönyv (a továbbiakban: Ptk.) is, bevezetve többek között a támogatott döntĂ©shozatal intĂ©zmĂ©nyĂ©t. A tanulmány cĂ©lja áttekinteni a hazai gondnoksági perek jogalkalmazĂłi gyakorlatának azĂłta eltelt, utĂłbbi öt Ă©vĂ©t. Tekintettel arra, hogy a majd hatvanezer gondnokság alatt Ă©lĹ‘ ember számára sorsdöntĹ‘ jelentĹ‘sĂ©gű a cselekvĹ‘kĂ©pessĂ©gĂĽket Ă©rintĹ‘ bĂrĂłsági döntĂ©s, Ăgy a szerzĹ‘k az alapjogkorlátozás alkotmányos keretei között elemzik a gondnoksági perek gyakorlatát. EbbĹ‘l az aspektusbĂłl vizsgáljuk a szĂĽksĂ©gessĂ©g Ă©s arányosság, a fokozatosság elveinek megvalĂłsulását, a gondnokság alá helyezĂ©s törvĂ©nyi feltĂ©teleinek kĂĽlönbözĹ‘ Ă©rtelmezĂ©sĂ©t, a „szakĂ©rtĹ‘i perekben” rejlĹ‘ veszĂ©lyek, vagy Ă©ppen az ĂĽgycsoportok egyenkĂ©nti vizsgálatának kĂ©rdĂ©seit
Study on medicinal chemistry of k203 in wistar rats and beagle dogs
K203 is an experimental bis-pyridinium mono-aldoxime type cholinesterase reactivator of potential use in organophosphate/ organophosphonate poisoning. Pharmacokinetics of K203 were examined in Wistar rats and beagle dogs using ion-pair HPLC. Serum and cerebrospinal fluid concentrations of K203 were determined using ion-pair reversedphase chromatography on octadecyl silica column. HPLC with ultraviolet detection was used for determination of serum concentration of K203 higher than 0.1 μg/mL while its low concentrations in cerebrospinal fluid required electrochemical detection (0.015 through 4 μg/mL range). In rats the serum levels of K203 followed zero order pharmacokinetics from 15 to 120 minutes post administration. Zero order pharmacokinetics was also observed in beagle dogs after low dose (15 μmol/kg) of K203 administration. High dose administration (250 ?mol/kg) led to subsequent hindered elimination from both cerebrospinal fluid and serum. © 2013 Bentham Science Publishers
