Experimental Study of Motion Modes of Discrete Drum with Different Input
Get PDFThe article presents an analysis of the dynamics of interaction of a single fiber with the sampling drum of a headset during pnevmomechanical spinning. The regularity is investigated and the equation of the movement of fibers on the surface of the tooth of the sampling drum headset is obtained. It was found that the dependences of the movement of fibers along the tooth at different angles of inclination, the distribution of fiber tension along the arc, and the distribution of fiber speeds in the region of the sampling arc have an increase property. As a result of the analysis of the tension and speed of the fibers, it was found that with the increase in the sampling zone, the tension force and speed of the fiber increase
A study the effect of brittle concrete working property by developing installation parameters (Subject Review)
Get PDFIn the past tense, studies relating to concrete with high performance have shown the harmful role of excess water in concrete. The reduction of this quantity of water, by using deflocculates and by correcting granular stacking via ultrafine, has led to gains in strength and known durability. As an extension of this scientific work, the observed improvement in the workability of these new concretes led the researchers to develop and make this property reliable. Today, in total continuity with high-performance concretes, it is a change of objectives constituting a veritable cultural revolution proposed by the self-compacting concretes: the study of the material is no longer governed solely by improving resistance and durability. However, these latter properties remain wedged at levels equivalent to or higher than those of joint concretes. In this area now, with self-compacting concretes, the ability to be easily placed work without vibration which has become priorities. These skills will have great consequences in terms of execution time, reduction of materials, quality of concreting, ease of implementation, respect for the neighborhood, and less hardship for the worker
Studying The Possibilities of Processing of Mining Slags
Get PDFThe article discusses the inevitability of copper losses due to slag, as well as the possibility of decreasing them through various approaches and the use of local secondary technogenic formations. It has been demonstrated that the developed and commonly used in industry slag decontamination procedures only partially alleviate the problem and result in large irreversible metal losses with dump slag. The primary elements that influence the size of the losses are identified, and recommendations for limiting their negative impact are made. The use of ideal mixing equipment is advised in this scenario because a maximum decrease in the residual copper concentration in the waste slag is possible. With the organization and implementation of low-waste technologies, it is feasible to achieve an increase in the complexity of raw material utilization. In this article discusses about information of studying the possibilities of processing of mining slags
Recommendations for the Effective Operation of MercedesBenz Bus Air Filters in Hot Climatic Conditions
Get PDFThis article is devoted to the regeneration of air filters Mercedes-Benz buses, justified the number of optimal regeneration of clogged air filters. The dynamics of the aerodynamic resistance of air filters is experimentally and theoretically proved, and the second-order polynomials are obtained for the prediction of the change in their resistance by applying the methods of mathematical statistics

Mathematical models for describing the turning process as a random non-stationary process
Get PDFIn this paper, we consider the description of the turning process as a non-stationary random process, we use the distribution function of the cutting parameters of the form and, by double logarithm, this model is reduced to the form of a linear model
Theoretical Foundations and Analysis of the Jerusalem Tubers
Get PDFCrisply gathered Jerusalem tubers contain inulinase, a protein that requires inactivation, since of its capacity to hydrolysis inulin into fructose, which can be devoured by microorganism amid marinating. As the traditional pickling process takes 6 months, and involves the addition of a large amount of salt (18–20%), this production strategy is uneconomical and increases the nitrite intake. Additionally, miscellaneous bacteria produced during pickling affect the product taste. In this study, the enzyme inactivation effects of NaCl, NaHCO3, and ultrasound were evaluated. NaHCO3 treatment results in the highest degree of enzyme inactivation; however, the quality and flavor of the obtained Jerusalem tubers pickles were not ideal. The Jerusalem tubers pickles in which the enzymes were inactivated using a combination of NaCl and ultrasound exhibited better flavor than those exposed to NaHCO3; further, this combination reduced the inulinase activity of the Jerusalem tubers to 2.50 U/mL, and maintained the inulin content at 61.22%. The strains LS3 and YS2, identified as Enterococcus facials and the salt-tolerant yeast respectively, were the dominant microorganisms isolated from the pickle juice. Jerusalem tubers with inactivated inulinase were pickled with microbial powder, separated, purified, and dried to remove the natural Jerusalem tubers sauce. This process shortened the fermentation cycle and improved product qualit
Calculation Pore Pressure Utilized Two Methods / Case Study of Zubair Oil Field.
Get PDFPore or formation pressure calculation is crucial to petroleum industry. There is currently no widely accepted approach for pore pressure estimation in carbonate reservoirs, and the results are still far from satisfactory. In this study, discussion two approaches called Eaton Slowness and Bowers Original method utilizing in prediction pore pressure. The concerned data (logs, calibration data, drilling, and mud report) and these data were utilized in Techlog 2015 software. Pore pressure in the Tanuma formation is around 4650 psi according to the Eaton data, compared to 3100 psi for the Bowers technique. Eaton's hypothetical mud weight at a certain depth was greater than the actual mud weight, however bowers' results showed that it was lower than the actual mud utilized for this well. When the results of two methods compared against mud weight and the pressure tests are both yield agreeable. Even with improved knowledge, the characteristics for reservoir formations may be was the impact of porous systems on velocities and numerous correlation aspects are still poorly understood. The Bowers method of pore pressure computation is substantially more accurate than the Eaton method
