Cultivation ofCalanus helgolandicus under controlled conditions

Cultivation of Neisseria gonorrhoeae under low-oxygen conditions.

Sixteen Neisseria gonorrhoeae strains were examined for their abilities to grow under reduced oxygen tension. Low oxygen tensions were developed by evacuation-replacement procedures in which anaerobes and oxidation-reduction indicators were used as controls. All strains survived 96 h in a medium reduced to below -125 mV without visible growth. Detectable growth occurred at 0.05% oxygen, and 33%...

Fed-batch Cultivation of Recombinant Escherichia coli Producing Human Interferon-γ Under Controlled Specific Growth Rate

Effects of Controlled Drainage Systems to prevent chemical soil degradation in the Area under Sugarcane Cultivation

The Imam Khomeini sugarcane agro-industry is one of ten sugarcane agro-industry plantations in Khuzestan province. As regard as the drains has been installed  in this plantation many years ago so there is water and salt balance in this land that is one of the condition for implementation controlled drainage. This research was designed to investigate the possibility of using a controlled drainag...

Leaf Segmentation under Loosely Controlled Conditions

We propose a robust and accurate method for segmenting specular objects acquired under loosely controlled conditions. We focus here on leaves because leaf segmentation plays a crucial role for plant identification, and accurately capturing the local boundary structures is critical for the success of the recognition. Popular techniques are based on Expectation-Maximization and estimate the color...

Herbicide Efficacy under Semi-controlled Conditions

Oneof the main causes of poorweed control on sugarcane farms is the occurrence of weed germination in periods during which demands on the farm's resources are at a maximum and during which wetconditions may prevent timely herbicide application or other weed control operations. It would therefore facilitate weed control if weed germination could be predicted from meteorological data and a knowle...
