Entre máquinas desejantes e máquinas de guerra
Authors: Pirola Émerson , Fortes Felipe
Published: November 2021

O artigo propõe uma análise conceitual introdutória ao problema do fascismo da forma em que este é desenvolvido nos dois volumes de Capitalismo e esquizofrenia, de Deleuze & Guattari. Um dos méritos da abordagem deleuze-guattariana, alinhada à tradição da “servidão voluntária”, é abordar a problemática do fascismo como um fenômeno desejante, sendo o desejo o motor de produção do campo social. No entanto, há uma mudança de tom na passagem de um volume a outro em relação à problemática do desejo, e daí deriva uma transformação na conceitualização do fascismo: Em O anti-Édipo o fascismo é entendido como um desvio das forças produtivas do desejo, através da inserção, no corpo do desejo, de fragmentos de códigos arcaicos trabalhando em uma reterritorialização em favor do e pelo socius: para conter uma desterritorialização absoluta do desejo que libertaria o campo social e a produção desejante do socius, se introduzem elementos de reterritorialização que impedem que o desejo atinja seu potencial de dissolução do socius. Já em Mil Platôs, junto a uma tomada da problemática do microfascismo como fenômeno molecular do desejo, temos uma análise que modifica os eixos da investigação: a partir de uma inversão da relação entre máquina de guerra e aparelho de Estado, temos a situação peculiar em que o Estado é tomado por uma máquina de guerra revolucionária fascista, isso é, o Estado é tomado por uma linha de destruição total e tem seus aparelhos de captura e aparatos burocráticos impregnados por um desejo fascista que tem na destruição “pura e simples” seu único fim tendencial, resultando em um Estado suicidário. Com estes desenvolvimentos conceituais podemos nos perguntar: quais as relações entre fascismo e Estado? Na mesma medida, é o caso de entender o que contemporaneamente vem sendo chamado de “neo-fascismo” dentro do quadro geral chamado por Deleuze & Guattari de pós-fascismo e, com isso, postular tanto um possível devir-fascista global quanto apontar alguns cuidados para evitá-lo e enfrentá-lo.

Published: November 2021

The possibility for manufacturing by cold extrusion of part such as shells made of corrosion-resistant and higstemperature steel is evaluated. It is shown that when extrusion such parts using combination of direct extrusion from workpiece with diameter equal to the diameter of the flange, followed by direct extrusion of the shell wall, number of intractable problems arise. Some of these problems relate to the design of production die to be fitted to mass produced standard presses. It is proposed to manufacture parts of the type using combination of extrusion of the shell walls from workpiece with diameter equal to its outer diameter, with simultaneous radial extrusion of the flange. Such technological solution can be implemented on domestic specialized presses.

BACKGROUND: The growth of allergic diseases dictates the necessity to develop new forms of therapeutic allergens since therapy with native water-salt extracts of allergens is unsafe and convenient. The risk of systemic side effects during allergen-specific immunotherapy sets the task for researchers to create modern therapeutic forms of allergens with high immunogenic and low allergenic activity. Our laboratory has been developing preparations for the diagnosis and treatment of house dust mites allergies for many years.
AIMS: To create modern therapeutic forms of allergen preparations from house dust mites of the genus Dermatophagoides that are intended for allergen-specific immunotherapy
MATERIALS AND METHODS: Physicochemical and immunobiological methods, such as electrophoresis in polyacrylamide gel, micropoint immunoblot, solid-phase enzyme-linked immunosorbent assay, and the reaction of binding inhibition of allergen-specific immunoglobulin E in the sera of patients were used to study the obtained preparations.
RESULTS: A technology has been developed to obtain a granular dosage form of a mixed allergen from Dermatophagoides pteronyssinus and Dermatophagoides farinae mites for sublingual use. This treatment form has successfully passed preclinical tests, has a pronounced immunogenic activity, and reduced allergenicity, and is convenient for pediatric practice. Allergoids, which are chemically modified preparations, are obtained to reduce allergenicity and increase therapeutic allergen immunogenicity. A succinylated monomeric house dust mites allergoid Dermatophagoides pteronyssinus was created and studied with the National Research Center, Institute of Immunology Federal Medical-Biological Agency of Russia. The study of the immunobiological properties of the obtained preparation showed that the monomeric allergoid has increased immunogenic and decreased allergenic activity contrary to the native water-salt extract.
CONCLUSIONS: The created forms of mite allergens can be used to treat patients who are sensitized to house dust mites of the genus Dermatophagoides after clinical trials.

This study seeks to explore the problem of the dichotomy of science and its solution in Islamic Higher Education. which is analyzed in the perspective of education policy regarding higher education regulations by using the content analysis method in the study of library research.
The issue of the dichotomy of science is actually a classic issue of the dark legacy of the past colonialism which Indonesia's founding fathers have been fighting for a long time. This real effort is proven by the issuance of a joint decree initiated by the Minister of Religion, KH. Wahid Hasyim and the Minister of Education of the Republic of Indonesia regarding the implementation of religious teaching in state educational institutions which are stipulated through the Regulation of the Minister of Religion No. 3 August 11, 1950.
In the study of Islamic education, there is a classification (taqsîm) of knowledge, the first is al-'ulum al-diniyyah (religious sciences) which is called religious science and the second is general science or general sciences.
In essence, Islam has never recognized the dichotomy of science (tafriqh), Islam only recognizes classification (taqsîm) based on the sequence and stages of learning, starting from fardlu 'ain and fardlu kifayah. The scholars and figures have formulated solutions starting from the regulatory aspect as stated in the joint regulation of the Minister of Religion and the Minister of Education, several other strengthening regulations through the 2003 National Education System formulation and the Higher Education Regulation, or in the form of ideas and ideas such as the tree of knowledge scheme, integration, integration. -interconnection and Naquib Al-Attas' ideal idea of ​​Islamization.

VIBRATIONS OF AN INSTANTLY LOADED DISSIPATIVE OSCILLATOR
Authors: Olshanskiy Vasyl , Slipchenko Maksym , Spolnik Oleksandr , Solona Olena
Published: November 2021

The work investigates non-stationary oscillations of dissipative oscillators. The joint influence of resistance forces of different nature in the composition of the dissipative force on the oscillations of an elastic linear oscillator caused by its instantaneous loading by a constant external force is investigated. The work was limited to the case of small displacements, when the elastic characteristic of the system can be considered linear. The problem is nonlinear due to the account of the action of the dry friction force, but it allows the construction of exact analytical solutions in elementary functions. In this work, by the method of adding solutions, formulas are derived for calculating the amplitude of oscillations and the duration of half cycles. First, a variant is considered when the resistance force consists of linear viscous and dry friction forces. Then a generalization is made to the case of three resistance forces. The third force is the force of positional friction, which arises in elastic elements such as a leaf spring. It is shown that as a result of the action of the total resistance force, the oscillatory process of a loaded oscillator has a finite number of cycles and is limited in time, which is usually observed in practice. The system dynamic factor is less than two. Examples of calculations that illustrate the possibilities of the stated theory are considered. To check the adequacy of the derived calculation formulas, numerical computer integration of the nonlinear differential equations of the oscillator motion was additionally carried out.

The full agreement of the numerical results obtained using various methods is shown. In addition to direct problems of dynamics, the inverse problems of determining the characteristics of the load and resistance from the results of measuring the amplitude of oscillations are also considered. The derived calculation formulas are also suitable for identifying the characteristics of the load and resistance based on the results of experimental measurements of the oscillation ranges. Examples of identifying these characteristics are given.

The study showed that the nonlinear problem of motion of an instantly loaded oscillator with the total resistance of several forces of different nature has an analytical solution in elementary functions. The presence of such resistance significantly affects the motion of the oscillator after loading. The constructed analytical solutions give results such as the numerical integration of the original nonlinear differential equation on a computer, which confirms the adequacy of the formulas obtained.

Published: November 2021

The high level of energy use by domestic producers does not allow for the competitiveness of livestock products in the domestic and foreign markets. Therefore, the effective functioning of farming enterprises requires the development and implementation of technologies that meet world standards for energy efficiency and reduce energy losses.

A very important and energy-consuming operation is the grinding of feed grains (wheat, barley, peas, corn, etc.). In the technological process of feed production, the share of energy consumption for grinding can reach up to 70%. Feed material usually has a high moisture content. In most cases, the grinding is performed by hammer mills. However, when grinding grain with high moisture content this crushing method (by hammer mills) is ineffective.

This article is devoted to solving the actual problem: minimizing energy consumption for grinding of feed grains when making feed for farm animals namely the theoretical study of the motion laws of the proposed technological equipment. Presented schematic diagram vibrаtion disk-type crusher for feed material realizes the idea of a combined interaction of vibration and rotational motion of equipment, a combination of shock and cutting impact of work items on the material.

This will allow to process raw material with high moisture content without significantly reducing the performance of the mashine and facilitates timely withdrawal of the product from the grinding zone.

Also, in order to establish the values of velocity of mass centers constituents vibration equipment kinematic analysis of the given machine graphic-analytical methods of theoretical mechanics and the theory of mechanisms and machines was performed, including established patterns of change of linear velocity of the centers of mass and structural elements in the future will help determine the total kinetic energy of this oscillatory system.

Authors: Rakhmanov Suleiman , Zdanevich Sergey
Published: November 2021

The results of the study of the dynamics of the mechanism for holding the mandrel of an automatic TPA mill are presented. The value of the axial force acting on the mandrel and the rod system of the mechanism of its holding is determined. Developed models of the mandrel retention mechanism have been developed, which made it possible to establish the nature of the development of dynamic processes on the output side of the automatic mill, taking into account the force parameters of the longitudinal rolling process of the sleeve and the parameters of the output side of the automatic mill. Mathematical models of the mandrel retention mechanism have been developed, taking into account the parameters of the technological process and the inertness of the rolled sleeve. The solution of the system of differential equations with variable coefficients is implemented numerically using the Runge-Kutta method for the corresponding dynamic models of the mandrel retention mechanism on the example of calculating the automatic mill TPA 350. The picture of the formation of dynamic processes in the mandrel retention mechanism during the implementation of the entire technological process of pipe production on an automatic mill has been clarified. taking into account the variable impact from the deformation zone and the change in the mass of the rolled sleeve. For various dynamic models, numerical solutions of problems were implemented, which made it possible to select the necessary technological and dynamic parameters of the mechanical system, to assign stable modes of rolling the sleeves on the automatic mill TPA 350. It is shown that the refined solution of the problem for three developed dynamic models of the mechanical system differs significantly from the previously known mathematical models. It has been established that the dynamics of the mechanism for holding the mandrel of the automatic TPA 350 mill is equivalent to the formation of the mechanism for the formation of different wall thickness of pipes. A mechanism for stabilizing the dynamics of the mandrel holding mechanism by separating the sections of the output side of the mill is proposed.
INVESTIGATION OF THE SPEED OF MOVEMENT OF COLD GAS DYNAMIC SPRAYING POWDER PARTICLES

Published: November 2021

The article shows the results of the study of the velocity of the sprayed powder particles on the example of cold gas-dynamic spraying of copper powder C01-11. Features and advantages of gas-dynamic spraying before other gas-thermal coating methods are given. The importance of the speed regime of coating and its influence on the formation of the coating is analyzed. A computational experimental method for determining the velocity of sprayed particles is proposed, as well as an experimental setup with the help of which it is possible to obtain objective data on the velocity regime of cold gas-dynamic coating. The design of the applied gas-dynamic spraying device is shown, which contains an electric heater of the compressed air flow and an accelerator of the heated compressed air into which the sprayed metal powder is driven due to the ejection effect. An experimental setup was used for the study, which contained two rotating disks mounted at a distance of 20 mm from each other on the shaft of a high-speed electric motor, with holes in the upper disk through which spraying occurs on the surface of the lower disk. Due to the fact that the disks with the spraying process rotate at a speed of 10587 rpm is the displacement of the sputtering figure on the lower disk relative to the projection of the hole of the upper disk on the lower disk. The magnitude of this displacement is calculated by the velocity of the particles of the sprayed powder, according to the above method. The parameters that are taken into account when calculating the speed of the spray particles of the powder is the diameter of the nozzle of the spray device 5 mm. The distance from the nozzle cut to the upper disk is 10 mm. The distance from the nozzle cut to the lower disk is 32 mm. The distance between the disks a = 22 mm. The radius on which the nozzle of the spray device is installed is 90 mm.

As a result of the experiments, it was found that when spraying copper powder C01-11 at a temperature of 20 ºC, the spraying speed is 232.2 m / s, which does not provide conditions for coating, and at elevated temperatures to 285 ºC quality coating was formed. The spraying speed was from 302.7 to 359.2 m / s for critical sections of 2.5 and 3.01 mm2, and the spraying area at higher speeds was approximately 20% higher than at lower speeds. This makes it possible for researchers to determine the velocity modes of spraying and, accordingly, to more accurately assign the optimal technological parameters to achieve the highest quality results of creating functional coatings.

Published: November 2021

Develop a mathematical model and calculated analytical dependences to determine the trajectories and parameters of grain movement on the surface of the vibrating feeder under the conditions of its introduction into the aspiration channel of the separator.

They are based on the methods of mathematical modeling and theoretical mechanics with the application of the equations of motion of a material point under the variable action of vibrations. Theoretical research was conducted using mathematical analysis and modeling theory. The research results are processed using elements of probability theory and mathematical statistics using application packages.

A mathematical description of the movement of grains of grain material components (GMC) on the surface of the vibrating feeder under the conditions of its introduction into the aspiration channel of the separator under the conditions of vibration on the GMC. The trajectories of grains on the surface of the vibrating feeder with different size are obtained.

The obtained equation of motion of the particle under the action of vibrations allows to determine the dependence of the velocity of the material in the vibrated fluidized bed on a number of factors: geometrical parameters of the vibrating feeder, feed angle, initial kinematic mode of grain material, kinematic mode of the vibrating feeder and friction coefficient.

The process of grain material movement on the flat surface of the vibrating feeder is described, which allows to determine the rational parameters of material introduction into the aspiration channel of the separator for its further fractionation.

The dependence for the function of the grain flow rate on the flat surface of the vibrating feeder is obtained, which allows to determine the parameters of the grain material distribution by the cross-sectional area of the aspiration channel of the separator.

The velocity of grain material on the flat surface of the vibrating feeder is estimated on the basis of a mathematical model constructed by hydrodynamic analogy, which in turn determines the analysis of grain recombination by the thickness of the vibrated liquid layer of grain material.
THE USE OF DISCRETE WAVELET ANALYSIS OF VIBRO-ACOUSTIC SIGNALS TO DETECT THE POWER SUPPLY ASYMMETRY OF ROTATING ACCOMPANYING ELECTRIC MACHINES
Authors: Graniak Valeriy , Gaidamak Oleg
Published: November 2021

The work shows that among the existing sufficiently described and studied approaches that are suitable for analyzing the temporal realization of a vibosignal, which can be obtained during the operation of a real electric machine, one can single out Fourier transforms and discrete wavelet transformations. An analysis of the descriptions of vibro-acoustic signals given in the literature, caused by the asymmetry of the power supply, shows that this defect leads to the appearance of oscillations that contain a harmonic component localized at the frequency of the supply voltage of the electrical network. This fact justifies the expediency of analyzing the frequency range, which includes the frequency of the supply voltage, and the selection of the mother wavelet, based on the features inherent in a single harmonic oscillation.

A method for detecting a defect in the asymmetry of power supply to rotating electric machines of alternating current using a discrete wavelet transformation of a vibro-acoustic signal is proposed. The frequency band has been established, which is advisable to analyze in order to identify the indicated defect.

It was found that the detection of a power asymmetry defect with the use of the wavelet transform of the temporal realization of the vibroacoustic signal is advisable to carry out using the Haar maternal wavelet function, which provides a combination of a high degree of affinity of the maternal wavelet with the form of vibration change due to the introduced asymmetry and relative the simplicity of such a transformation.

It is shown that when detecting power asymmetry, it is advisable to analyze the behavior of the wavelet coefficients of the frequency band, which includes the frequency of the supply voltage of the electric machine. Since the influence of the indicated defect on other frequency bands will be minimal, the analysis of the behavior of their wavelet transform coefficients in order to identify the indicated defect is ineffective.

A numerical criterion for assessing the influence of power asymmetry on the wavelet transform coefficients is proposed in the form of the mean square value of the wavelet coefficients of the informative frequency band in the study of the time interval, which significantly exceeds the period of the supply voltage of the electric machine. It is shown that this criterion has a reduced sensitivity to the impact of non-informative single disturbances that may arise during the operation of an electric machine.

VIBRATION DIAGNOSTICS OF FATIFUE DAMAGE IN STRUCTURAL ELEMENTS OF GAS TURBINE ENGINES AT THE REPAIR STAGE
Authors: Bovsunovsky Anatoliy
Published: November 2021

Vibration diagnostics of damage belongs to the class of non-destructive methods, which usually do not take long time. However, the main problem of vibration diagnostics is relatively low sensitivity to the critical damage of fatigue crack type, which arises because of long time accumulation of plastic deformation. To improve the sensitivity and reliability of vibration diagnostics of damage two methods were considered. First method was based on the fact, that a characteristic feature of vibrations of structural elements with fatigue crack is the occurrence of non-linear resonances (sub- and super-harmonic) and significant non-linearity of vibration response at these resonances. Secon one – on the fact, that quite noticeable in certain cases increase of damping characteristic caused by a crack can be observed. Analytical and experimental studies of these methods were carried out as applied to the blades of aircraft gas turbine engines. As a result of the studies, the intensity of change in parameter of super-harmonic resonance and in damping characteristics at different parameters of crack was determined. Besides, the experimental techniques for vibration testing of turbine blades were developed. There was demonstrated, that the sensitivity of both considered methods of vibration diagnostics is several orders of magnitude higher than the sensitivity of conventional methods based on the change in natural frequencies and mode shapes, and they can be effectively used for the diagnostics of blades on the stage of engine repair. All the other conditions being equal, second-order superharmonic resonance demonstrates a higher sensitivity to the presence of cracks than the damping characteristic. The smallest crack with an area of 0.2% considered in the work causes a reliably recorded non-linearity of vibration response at superharmonic resonance of order of 2/1. At this the change of damping characteristic slightly exceeds the error of experiment.

In conventional data envelopment analysis (DEA) models, the relative efficiency of decision making units (DMUs) is evaluated while all measures with certain input and/or output status are considered as continuous data without upper and/or lower bounds. However, there are occasions in real-world applications that the efficiency of firms must be assessed while bounded elements, discrete values, and flexible measures are present. For this purpose, the current study proposes DEA-based approaches to estimate the relative efficiency of DMUs where bounded factors, integer values, and flexible measures exist. To illustrate it, radial models based on two aspects, individual and aggregate, are introduced to measure the performance of entities and to handle the status of the flexible measure such that there are bounded components and discrete data. Applications of approaches proposed in the areas of quality management, highway maintenance patrols, and university performance measurement are given to clarify the issue and to show their practicability. It was found that the introduced procedure can determine practical projection points for bounded measures and integer values (from the individual DMU viewpoint) and can classify flexible measures along with evaluation of DMUs relative efficiency.

Introduction. To analyse the clinical and epidemiological characteristics and mortality-related factors of patients admitted to a secondary hospital with Infective Endocarditis (IE). Methods. Observational study of a cohort of patients who have been diagnosed with IE in a secondary hospital and evaluated in accordance with a pre-established protocol. Results. A total of 101 cases were evaluated (years 2000-2017), with an average age of 64 years and a male-to-female ratio of 2:1. 76% of the cases had an age-adjusted Charlson comorbidity index of >6, with 21% having had a dental procedure and 36% with a history of heart valve disease. The most common microorganism was methicillin-susceptible S. aureus (36%), with bacterial focus of unknown origin in 54%. The diagnostic delay time was 12 days in patients who were transferred, compared to 8 days in patients who were not transferred (p=0.07); the median surgery indication delay time was 5 days (IQR 13.5). The in-hospital mortality rate was 34.6% and the prognostic factors independently associated with mortality were: cerebrovascular events (OR 98.7%, 95% CI, 70.9–164.4); heart failure (OR 27.3, 95% CI, 10.2–149.1); and unsuitable antibiotic treatment (OR 7.2, 95% CI, 1.5–10.5). The mortality rate of the patients who were transferred and who therefore underwent surgery was 20% (5/25). Conclusions. The onset of cerebrovascular events, heart failure and unsuitable antibiotic treatment are independently and significantly associated with in-hospital mortality. The mortality rate was higher than the published average (35%); the diagnostic delay was greater in patients for whom surgery was indicated.

Kesehatan mental yang baik didukung oleh beberapa faktor, salah satunya adalah regulasi emosi yang baik. Di Indonesia pembelajaran mengenai emosi biasa dimulai sejak dini, yaitu pada umur 7-10 tahun. Regulasi emosi bisa dipelajari oleh anak-anak secara adaptif, yaitu  dengan melihat kondisi sosial dan lingkungan. Anak-anak biasa meniru perilaku dan cara penyampaian ekspresi orang-orang disekitar mereka. Pada umur 7-9 tahun, kemampuan metakognisi anak sedang berkembang pesat, sehingga metode refleksi dapat menjadi media pembelajaran regulasi emosi. Oleh sebab itu, dibuat “The Great Explorer’s Journal” sebagai salah satu alat pembelajaran regulasi emosi untuk anak berusia 7-9 tahun. Pada perancangan ini, dilakukan penelitian yang dapat mendukung pendesainan produk “The Great Explorer’ Journal”. Dari hasil penelitian, ditemukan bahwa diperlukan beberapa aspek untuk ditonjolkan saat mendesain jurnal seperti: Cerita, karakter/tokoh, serta interaksi yang sesuai dengan target umur. Pemilihan warna dan typeface juga harus yang menggambarkan keceriaan yang dinamis, untuk membuat Anak tetap tertarik dan konsisten mengisi jurnal Karakter menggambarkan karakter yang bukan sempurna, namun terus berusaha dan pengertian. Untuk media komunikasi dan pemasaran, harus juga disesuaikan dengan kebutuhan orang tua untuk memahami urgensi permasalahan yang ada. Setelah mendesain, hasil ini lalu diujikan kepada expert users dan extreme users, dan khayalak, dan hasilnya adalah mayoritas responden mengatakan secara desain sudah baik dan cocok untuk anak-anak, namun dalam beberapa media komunikasi, informasi Tidak lengkap/tidak jelas, Serta dalam Produk sendiri, ada beberapa copywriting yang ambigu. Lalu revisi pun dilakukan untuk mengatasi masalah ini, agar produk juga dapat digunakan dengan lebih efektif.

Minuman segar terutama es campur merupakan hidangan yang seringkali dijumpai di seluruh daerah di Indonesia dan setiap daerah tentunya memiliki keunikannya masing-masing. Di Tangerang terdapat sebuah toko es campur yang berdiri sejak 1980 dan terletak di kawasan kuliner Pasar Lama Tangerang yaitu Es Buntin. Es Buntin memiliki keunikannya tersendiri karena berhasil mempertahankan konsistensi rasa, bentuk, serta terus berinovasi dengan berbagai macam menu unik lainnya seperti Es Putsal dan Es Bumi Hangus. Namun selama 40 tahun berdiri, Es Buntin tidak pernah memiliki identitas yang konsisten dan jelas, serta kerap kali dianggap sebagai merek yang kuno oleh masyarakat khususnya generasi muda, sehingga mengakibatkan perubahan segmentasi yang berdampak pada penurunan omset dari Es Buntin. Oleh karena itu, Es Buntin membutuhkan perancangan identitas berupa logo, elemen grafis serta yang lainnya dengan sesuai agar dapat memenuhi target market yang dituju serta merepresentasikan wajah baru sesuai perkembangan jaman. Metode penelitian yang digunakan adalah metode campuran yaitu kuantitatif berupa kuesioner yang disebar secara daring dan kualitatif berupa wawancara dengan pihak-pihak terkait.
