A Simple and Inexpensive Flea-Proof Cage

Dynamics of a Single Point Mooring Marine Aquaculture Cage as a Simple Vibrating System

The increasing world demand for fish cannot be met by capture fisheries. Aquaculture production is increasing and nowadays cage culture has an important role in meeting the world’s fish demand. The design of the physical structure of a cage is determined by the oceanographic conditions of the culture site. Each design is site-specific and knowledge of the topography, wind force and direct...

A simple proof of Zariski's Lemma

‎Our aim in this very short note is to show that the proof of the‎ ‎following well-known fundamental lemma of Zariski follows from an‎ ‎argument similar to the proof of the fact that the rational field‎ ‎$mathbb{Q}$ is not a finitely generated $mathbb{Z}$-algebra.

A Simple, Inexpensive, and Rapid Method to Determine Toxicity Using a Bacterial Indicator Organism

A simple, inexpensive and rapid method to determine the toxicity of compounds, isolated chemicals, soil samples, and water samples has been developed. The test uses the bacterium, Rhizobium meliloti, as the indicator organism. Toxicity values obtained with this test are complarable to those obtained with more familiar tests like the sand flea Daphnia magna, Microtox TM , and tests using animal ...
