Recent field studies indicate that dinoflagellates are key degraders of copepod fecal pellets. This study is the first to publish direct evidence of pellet grazing by dinoflagellates. Feeding and growth on copepod fecal pellets were studied for both heterotrophic (4 species) and mixotrophic dinoflagellates (3 species) using a combination of classic incubation experiments and video recordings of...

The microinjection of cytoplasm taken from one strain of large free-living amoeba into another strain is followed by an incompatibility phenomenon, the inhibition of division amongst the recipient cells. The post-microsomal supernatant fraction from Amoeba discoides (T1D13) injected into A. proteus (T1P) inhibited division in 90% of the injected cells. Further centrifugation of this fraction yi...

Background: The dose rate distribution delivered by a low dose rate 137Cs pellet source, a spherical source used within the source trains of the Selectron gynecological brachytherapy system, was investigated using the MCNP4C Monte Carlo code. Materials and Methods: The calculations were performed in both water and Plexiglas and the absolute dose rate distribution for a single pellet s...

Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal man...

Background Carbon monoxide is the leading cause of mortality from unintentional poisoning in Slovenia. It has been shown that carbon monoxide levels can rise in wood pellet storerooms because of chemical degradation of pellets, even at room temperature. We present a case of lethal carbon monoxide poisoning with first responder carbon monoxide exposure. Aims To highlight the dangers rescuers f...

Reasoning capability is of crucial importance to many applications developed for the Semantic Web. Description Logics provide sound and complete reasoning algorithms that can effectively handle the DL fragment of the Web Ontology Language (OWL). However, existing DL reasoners were implemented long before OWL came into existence and lack some features that are essential for Semantic Web applicat...

Pelleting was introduced into Europe about 1920 and into the U.S. feed industry in the late 1920's (Schoeff, 1994). Its popularity has grown steadily until about 80% of all feed in the U.S. are currently pelleted. Today, the process is widely used because of both the physical and the nutritional benefits it provides. The physical benefits include improved ease of handling, reduced ingredient se...

agglomeration followed by pelleting is an efficient method to decrease transport costs and increase economic efficiency of composting municipal waste. the moisture content of compost is the most important parameter of the pellet making process for any type of manufacturing device. the experiments in this study were done at moisture contents of 35%, 45% and 50% at extruder shaft rotational speed...

In situ commissioning of the Blower-gun injector for launching cryogenic deuterium pellets at ASDEX Upgrade tokamak was performed. This injector is designed for high repetitive launch of small pellets for edge localised modes pacing experiments. During the investigation the final injection geometry was simulated with pellets passing to the torus through a 5.5 m long guiding tube. For investigat...

One of the main challenges posed recently on pellet launcher systems in fusion-oriented plasma physics is the control of the plasma edge region. Strong energy bursts ejected from the plasma due to edge localized modes (ELMs) can form a severe threat for in-vessel components but can be mitigated by sufficiently frequent triggering of the underlying instabilities using hydrogen isotope pellet inj...
