Ibrahimi, Izet, Nurten Deva et Sabri Mehmeti. « Optimalization of the Ferronickel Production Process through Improving Desulfurization Effectiveness ». Civil Engineering Journal 6, no 5 (1 mai 2020) : 907–18. http://dx.doi.org/10.28991/cej-2020-03091516.
Desulphurization of Ferronickel in the converters with oxygen is the most complex part of the technological process in the Drenas foundry. Sulphur in the ferronickel melting is mostly in the form of FeS, with a melting temperature of 1195oC, and it has tendency to dissolve indefinitely in liquid iron. Our objective is to determine the sulphur removal coefficient, as a key indicator of the desulphurization efficiency in the converter, by measuring the activity and concentration of sulphur and other elements in liquid Fe and melting. Determination of this coefficient is done according to the analytical method, while comparing the current process parameters with those of the new desulfurization methods, other indicators of the refining process are determined. The refining process and the effective conduct of the study depend on the XRD analysis database of metal and slag, and as well of the technological refining process analysis data. Research has shown that desulfurization efficiency is a function of the sulphur removal coefficient, respectively; metal composition, slag, oxygen activity, CaO/SiO2 ratio, sulphide capacity, fluidity, surface pressure, etc.). In addition to this coefficient, other indicators of refining process optimization are defined.

AbstractCurrently in Russia and other countries in family farms there is a demand for lowering cost of animal production. Main direction to achieve new terchnological solutions characterized by low energy constumption and high efficiency with maintaining high quality of product (mineral). For example, lately in animal production are acquired concentrates with low unity costs. Realising targets releated with lowering costs of forage production with usage comminution and crease of grain. Previously conducted own researches and literature analises shows, that currently used solutions are characterized by big errors made by construction of the devices, and technology effect of obtained product (grain). The paper presents the criteria for optimalization of technical indicators of shredding devices affecting the quality of the product.

Mooijman, K. A., A. H. Havelaar, J. A. Hoekstra et N. G. W. N. van Strijp-Lockefeer. « Production and Control of Reference Materials for Water Microbiology ». Water Science and Technology 24, no 2 (1 juillet 1991) : 53–56. http://dx.doi.org/10.2166/wst.1991.0029.
Reference materials for water microbiology were prepared by spray-drying milk, artificially contaminated with a known test strain. The resulting highly contaminated milk powder was mixed with sterile milk powder to a contamination level of 2000-3000 cfu/g. Gelatin capsules were filled with the mixture (0.2 g/capsule) to produce the reference materials. Test strains used were: WR1 Escherichia coli, WR3 Enterobacter cloacae, WR63 Enterococcus faecium and WR51 Staphylococcus spec. Optimalization of the mixing procedure and aging of the highly contaminated milk powder resulted in relatively homogeneous and stable reference materials. Short-time challenge tests at “high” temperatures (30 and 37 °C) may be predictive for long-term stability at “low” temperatures (4-6 °C). Reference materials with strain WR3 were stable for one week at 30 °C and for at least 6 months at 4-6 °C. Possible applications of the reference materials are: quality control of routine measurements, comparison of the efficiency of different culturing methods and as a standardized sample in collaborative studies.

Mézes, Lili, Tibor Bíró, János Tamás et Mihály Petis. « The examination of poultry feather digestility for biogas production ». Acta Agraria Debreceniensis, no 26 (16 juillet 2007) : 113–18. http://dx.doi.org/10.34101/actaagrar/26/3064.
The aim of this research was the elaboration of the technological parameters of biological digestion and biogas production from poultry feather produced in large quantities by slaughterhouses. Feather protein was digested by Bacillus licheniformis, keratin desintegrator bacteria. Investigations focused on the optimalization of parameters influencing poultry feather biodegradation. The optimal range of pH, temperature, feather size and bacillus:feather ratio were determined in the experiments as well as the analysis of relationship between the examined parameters. In order to be able to track the dinamics of the biodegradation, we determined the extintion level of the liquid phase of the biodegraded material in the different experimental treatments. The results showed that the rate of hydrolisis was significantly higher in the treatments with bacteria than in the treatments without it. The most extensive digestion were observed in case of 1:3 feather:water ratio. The highest intensity of feather digestion were detected in the treatment with 1% microbe ratio.

The aim of this research was the elaboration of the technological parameters of heat pre-treatment and microbial digestion of poultry feathers for biogas production. Feathers were treated at 70, 100, 140 °C, and subsequently digested by Bacillus licheniformis, or keratin disintegrator bacteria. Investigations focused on the optimalization of parameters influencing poultry feather biodegradation. The optimal range of pH, temperature,feather size and bacillus:feather ratio were determined in the experiments, as well as the analysis of relationship between the examined parameters. In order to be able to track the dynamics of the biodegradation, we determined the extinction level of the liquid phase of the biodegraded material in the different experimental treatments. The results showed that the rate of hydrolysis was significantly higher in the treatments with bacteria than in the treatments without it. Regarding the pretreatments at 70, 100 and 140 °C, the digestion of feather was the most intensive at 70 °C. The most extensive digestion was observed in case of 1:3 feather:water ratio. The highest intensity of feather digestion wasdetected in the treatment with 1% microbe ratio.

Sidoarjo mudflow or known as Lusi (Lumpur Sidoarjo) is an ecological disaster that has caused the community fret. Most of them haven’t known that the mud contains elements that can produce electricity. This research aims to find the basic value that can be obtained from ecological disaster. The research design uses electrochemical method development with magnesium and copper electrodes. The result of the electric power that can be generated is 7,07135 watt/hour. It can reach an area of 4.405986 km2 or as wide as one residential in an electric production plant. The use of Lusi is very effective because it contains high metal and high salt content. The abundant amount of Lusi can be utilized effectively throughout this way

This diploma thesis focuses on the optimization of bacterial cellulose production by Komagateibacter xylinus DSM 46604. The theoretical part of this thesis describes the properties of bacterial cellulose, its production and application possibilities. The experimental part aimed to assess the effect of different cultivation conditions on the production yields of bacterial cellulose. The effects of several cultivation strategies have been studied such as: (1) effect of acetate buffer used as a medium, (2) impact of oil added into the medium, (3) fed-batch cultivation, (4) variation of the volume of cultivation vessel and cultivation media and (5) aeration. In addition to the production of relatively thin samples, up to 100 µm was synthesized unique 3D structured bacterial cellulose in the form of cylinders, with a height up to 2 cm. The growth of bacterial cellulose in the form of cylinders was achieved by dynamically cultivating K. xylinus in combination with fed-batch approach.
