Abstract:

Şırnak asphaltite slime below 200 micron size is processed. The clean coal products of the column flotation are received with mid-products and shale settlements in the modified column cell in the baffled form. The use of hydrocyclone, agglomerate thickener and wash decantation has been a suitable potential method after the driven and internal loop column flotation. With this method, ultrafine sized oily sludges with high efficiency and low solid rate coal washing are provided. It also enabled highly efficient wastewater treatment as a result of separating the oil with czar foam. Therefore, the

Abstract:

The problems of processing iron ore tailings of wet concentration plants and wastes with high content of iron, contaminated by oil products are actual from both points of view of ecology and economy. One of the reasons restraining solving the problem is absence of technologies ensuring to involve such wastes into industrial turnover. In the process` of the research, composition and opening degree of ore and non-metallic minerals of concentration slime tailing of Magnitogorsk steel-works (MMK) were studied and technology of their concentration was elaborated.

Abstract For breakdown of each type of stable oil-water and oil-slime emulsions, individual approaches for selection of effective emulsion breakers or their compositions with the determination of optimal conditions for their use are required. Solution to such a complex problem is achieved using integrated approach that includes a number of colloidal-chemical, technological and other research methods. In this case, we offer technology of dehydration and desalting of stable water-oil and oil-slime emulsions using the created compositions of emulsion breakers and viscosity-lowering agent, i.e. ga

With the continuous depletion of primary tin ores, tin tailings has become an important source for the production of tin; however, the large-scale utilization of tin tailings is disappointedly scarce, due to its leanness in valuable minerals and insufficient methods available for processing such low-grade tailings.

Abstract:

An immersion experiment was conducted in the Manila South Harbor to document the development of sessile biofouling communities. Test panels were submerged below the sea surface in April 2012 for short- (one and three months) and long-term (one year) exposures in seawater, then foauling types and occurrences were scored based on digital images of panel surfaces. The short-term immersed panels were found with significant cover of soft fouling (undet.), slime, and the invasive Balanus (=Amphibalanus) amphitrite. These also filled the long-term immersed panels, although some fell off due to mortal

There is scarce information on cationic surfactants’ biocidal and corrosion inhbibition effects on Slime-Forming Bacteria (SFB) isolated from oil field formation water. Therefore, this work focused on the the synthesis of a cationic surfactant (CS) to increase its features by capping different metal nanoparticles (zinc, ZnNPs-C-CS; manganese, MnNPs-C-CS and tin, SnNPs-C-CS) and used them as biocides and corrosion inhibitors. The cationic surfactant was synthesized and characterized by Fourier-Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. Afterwards, different nan

Abstract:

Acne is the condition of abnormal skin which is indicated by inflammation caused by the bacterial infection of Propionibacterium acnes. The natural one which can be used for the medical treatment of acne is the snail mucus (Achatina fulica). The achasin protein of it has antibacterial activity. That snail mucus was made to the emulgel form. This research has used an experimental method and the emulgel formulation used the various concentration of emulsifying agents and the gelling agent. They were Tween 80 1.76%, 2.44%, 3.12%, Span 80 2.24%, 4.06%, 5.88% and HPMC 3.5%, 4.5%, 5.5%. Other additi

Abstract:

In the development of the cellular slime moldDictyostelium discoideumthere is a stage in which the aggregated amoebae form a migrating slug that moves forward in a polar fashion, showing sensitive orientation to environmental cues, as well as early signs of differentiation into anterior prestalk and posterior prespore cells. Heretofore it has been difficult to follow the movement of the individual cells within the slug, but a new method is described in which small, flat (one cell thick) slugs are produced in a glass-mineral oil interface where one can follow the movement of all the cells.

Abstract:

The Biological Aerated Filter process (BAF process) is ideal for reclamation and reuse of wastewater. It features excellent removal of organic matter and SS. Moreover, it features easy maintenance and achieves energy-saving and space-conservation. Results of applying this BAF process for the reclamation and reuse of domestic-type wastewater in an office building, castor oil containing industrial wastewater in an aluminium rolling mill, and industrial wastewater in a paper mill are summarized in the following. Treatment of office building domestic-type wastewater. Combining the BAF process with

Galangal (Alpinia galanga (L.) Willd.) and lemongrass (Cymbopogon citratus (DC.) Stapf) are spices known for their antimicrobial activity and potentially developed into a natural food preservative. This study evaluated the potential development of galangal and lemongrass oils and extracts for natural food preservatives. The essential oils and water extracts of galangal and lemongrass were obtained by water and steam distillation and infusion methods, respectively. Chicken fillets were immersed in three concentrations of galangal and lemongrass oils and extracts, with sterile water as the contr

Abstract:

As the core component of a ship’s engine room, the operation of a marine diesel engine (MDE) directly affects the economy and safety of the entire vessel. Predicting the future changes in the status parameters of a MDE helps to understand the operational status, enabling timely warnings to the engine crew, and to ensure the safe navigation of the vessel. Therefore, this paper combines the temporal pattern attention mechanism with the bidirectional long short-term memory (BiLSTM) network to propose a novel trend prediction method for short-term exhaust gas temperature (EGT) forecasting.

Dolníček (2020) described several occurrences of bog iron (limonite), which according to his article originates in recent streams by chemical precipitation, without the important role of microorganisms on this process. However, similar occurrences of reddish or orange slime, frequently accompanied by oil-like films floating on the water, are according to many papers ascribed to the biogenic iron oxidation by bacteria. To solve the origin of such precipitates, we have sampled similar materials in four places near Ostrava - Hrabová, two close to Řepiště and Staříč, and also two sites in the vici

The jam fault diagnosis of slide valve oil motive has great significance on the safe and stable operation of steam turbine. As limited data available from DEH, the jam fault is difficultly diagnosed directly by DEH data. This paper defines insensitivity to represent the level of the jam fault of slide valve oil motive system. Through the simulation and research of the jam fault features of the slide valve oil motive, the relationship between the rate of change of the input signal and the insensitivity of the jam fault diagnosis is be found .
