Fermentative hydrogen production research grows rapidly around the globe to harness “clean energy” by the utilization of renewable feedstock, which can reduce climate change impacts as well as able to resolve concerns related to fossil fuel consumption. Biohydrogen production technologies have been carried out in various modes of operation among which continuous systems promote scale-up and bioH2...
Many of flat rolled products manufacturers are never subjected to a batch annealing practice. Prime high volume examples are AlMnMg (3004, 3014) and AlMg4.5Mn (5182) families of alloys and the similar is used for deep drawn products. If the exit temperature of the last hot rolling pass is high that the material self-anneals, which promotes to form the earing 45° from the earing 90° of the hot rolling...
The mathematical model for the change of species number in phytoplankton from Lake Stechlin was developed in the other our work, where the species was separated rare and frequent ones. In general case both type species can be settled in and extinct from the ecosystems can be transformed from each to other and a complicate (connected) differential equation system used for description could possible...
Nowadays environmental protection is one of the most important problems. Industrial firms are expected to reduce continuously the environmental load, meanwhile enhancing their productivity. In our study a procedure was developed for the management of the waste water of a pharmaceutical process. The parameters of the waste water, which is flowing into the sewerage system, are generally below the permitted...
