Precursors of methane formation by cell-free extracts of the obligat,c anacrobc, Methanobacillus omelianskii, include carbon dioxide, pyruvate, and serine (1). Recently, methylcobalamin, CH,-Bil (2-4), and N”-methyltetrahydrofolate, 5-CH3-H4-folate, have been shown to be substrates for cell-free methane formation (5). This communication is concerned with the role of tetrahydrofolate, H1-folate,...

Metabacetus willi sp. n. (type locality: Indonesia, Central Java Province, Purworejo Regency, Kaligesing District, cave Seplawan near Donorejo) and Rhytiferonia beroni sp. n. (type locality: Papua New Guinea, West Sepik Province, Bonforok bil, Tifalmin, 1600 m) are described. Two new combinations: Poecilus (Ancholeus) campania (Andrewes, 1937), comb. n. of Feronia campania Andrewes, 1937, Arist...

Povzetek. V delu sta predstavljena vrtenje in pospeševanje ročne žiroskopske naprave Powerball z robotom. Čeprav povprečen uporabnik z nekaj vaje nima težav s sinhroniziranim pospeševanjem vrtenja naprave, pa je za robota to zahtevna naloga. Izvedene meritve gibanja človeka med pospeševanjem naprave, so pokazale potreben pogoj za pospeševanje – sinhronizacijo gibanja z navorom, ki deluje na rok...

Neonatal cholestasis is characterized by an elevation of conjugated bilirubin. It occurs in approximately 1 in 2500 term infants. Gaucher Disease (GD) is an exceptionally rare cause of neonatal cholestasis. We report a male term newborn with a blueberry muffin rash, hepatomegaly and massive splenomegaly at birth. His total serum bilirubin (TSB)/direct was 13.5/11.9 mg/dL, and platelet count 20,...

It is difficult to generate raster Digital Elevation Models (DEMs) from terrain mass point data sets too large to fit into memory, such as those obtained by LIDAR. We describe prototype tools for streaming DEM generation that use memory and disk I/O very efficiently. From 500 million bare-earth LIDAR double precision points (11.2 GB) our tool can, in just over an hour on a standard laptop with ...

Hemobilia is the result of a pathological communication between bile duct and intra or extrahepatic vessel. 40% to 60% of the haemobilia cases are Iatrogenic, and the other causes are either vascular malformations or hepatic blunt trauma. We describe the case history of a patient in which laparoscopic cholecystectomy was complicated 3 months later by massive hemobilia. The cause of haemorrhage ...

Povzetek. V članku sta predstavljeni implementacija in uporaba prosto dostopnega operacijskega sistema realnega časa na robotskem krmilniku DSP-2. Vgrajeni robotski krmilnik, ki je bil razvit na Fakulteti za elektrotehniko računalništvo in informatiko Univerze v Mariboru, se uporablja pretežno v pedagoškem procesu za vodenje večosnih mehanizmov. Dodatno je bila k sami implementaciji operacijske...

We construct a Teichmüller curve uniformized by the Fuchsian triangle group ∆(m, n, ∞) for every m < n ≤ ∞. Our construction includes the Teichmüller curves constructed by Veech and Ward as special cases. The construction essentially relies on properties of hypergeometric differential operators. For small m, we find bil-liard tables that generate these Teichmüller curves. We interprete some of ...

In this paper we show how the notion of context has been reened in order to fullll the requirements posed by a natural language processing system. We describe the context model of the speech translation system verbmobil which has been derived from constraints given by various subcomponents of the system. In verbmo-bil context is stored in the dialogue memory which is incrementally constructed b...
