This overview covers the basic microbial ecology of recirculating hydroponic solutions. Examples from NASA and Soviet CELSS tests and the commercial hydroponic industry will be used. The sources of microorganisms in nutrient solutions include air, water, seeds, plant containers and plumbing, biological vectors, and personnel. Microbial fates include growth, death, and emigration. Important micr...
At the end of his review The Fifth Corner Four: An Essay on Buddhist Metaphysics and Catuṣkoṭi by Graham Priest, Mark Siderits (2019) remarks:
Abstract The Japanese beetle Popillia japonica is an invasive alien species recently introduced and established in Northern Italy. Adult beetles are very polyphagous feed on vines, fruit trees, forest crops, vegetables, ornamental wild plant species. Eggs usually laid by females moist grassland the summer, singly or small clusters. Larvae roots may be transported soil of plants for planting gro...
INTRODUCTION No cases of human brucellosis caused by Brucella suis has been reported in Spain. METHODS This study involved interviews with the case and his co-workers, inspection of their workplace, checking infection control measures, and typing the Brucella strain isolated in the blood culture. RESULTS Brucella suis biovar 1 strain 1330 was isolated from a patient who worked in a waste tr...
The two well known techniques which are used in plant-nutrition studies are conveniently designated the solution-culture method and the sand-culture method. Some other slightly soluble materials, such as cinders, gravel, vermiculite, and Sponge Rok or various combinations of these may be substituted for sand. The use of slightly soluble material as a medium, to which the nutrient solution is pr...
In transportation via containers, unbalanced movement of loaded containers forces shipping companies to reposition empty containers. This study addresses the problem of empty container repositioning (ECR) in the distribution network of a European logistics company, where some restrictions impose decision making in an uncertain environment. The problem involves dispatching empty contain...
Pump-type containers are easy to use and also hygienic because the contents do not contact with the air. In this regard, pump-type containers are widely used from detergent to cosmetics. However, sometimes users have to throw the lotions away even if there is still remaining lotion in containers. Thus there is a need to take the measures against the pumptype containers that cause a waste. An ex...
We introduce the notion of containers as a mathematical formalisation of the idea that many important datatypes consist of templates where data is stored. We show that containers have good closure properties under a variety of constructions including the formation of initial algebras and final coalgebras. We also show that containers include strictly positive types and shapely types but that th...
In component-based systems, fault-tolerance concerns are typically handled by manually programmed fault containers. The purpose of fault containers is to prevent error propagation across component boundaries by means of redundant service providers. However, manually programmed fault containers are often subject to evolutionary pressure when components change. In this paper we present a meta-lev...
