Numerical modeling of hydrodynamics of spouted bed in solid fuel boiler

The issues of numerical modeling of hydrodynamics of a spouted fuel bed in the furnace of a solid-fuel boiler are considered. At present, solid-fuel boilers are widely used in the power industry of the Russian Federation, with the share of coal-fired generation to remain significant in the projected terms. Therefore, the study of the efficiency of thermal and hydrodynamic processes that ensure the implementation of clean coal technologies is a relevant task both today and in the long term. The article presents the following main stages of numerical modelling of the hydrodynamics of the spouted bed: problem formulation with selection of boundary and initial conditions, methods of solving the Navier-Stokes and continuity equations for the air flow, Newton's equations and diffusion equations for particles. The k-omega turbulence model was used in the calculations that is described by means of two partial differential equations for the variables k (kinetic energy of turbulence) and omega (specific dissipation rate). A comparative analysis of environmental advantages and disadvantages of existing methods of combustion of low-grade coal in schemes with in-cycle gasification (ICG) is carried out. Advantages and difficulties of switching to structures with CFB in the spouted bed mode are shown. Numerical modeling of the cold spouted bed created by means of particle injection is performed, a set of initial settings and boundary conditions is presented, the adequacy of the obtained results is verified by hydrodynamic characteristics of the isothermal process. The obtained results allow us to proceed to the next stages with non-isothermal models, with heat exchange and combustion reactions in the spouted bed of coal taken into account. The following refinement of the physical model will allow to achieve more accurate and reliable results and to ensure their correct scaling.

Biomechanical study of a biplanar double support screw (BDSF) technique based on Pauwels angle in femoral neck fractures: finite element analysis

ObjectiveThe objective of the present study is to conduct a comparative analysis of the biomechanical advantages and disadvantages associated with a biplanar double support screw (BDSF) internal fixation device.MethodsTwo distinct femoral neck fracture models, one with a 30° angle and the other with a 70° angle, were created using a verified and effective finite element model. Accordingly, a total of eight groups of finite element models were utilized, each implanted with different configurations of fixation devices, including distal screw 150° BDSF, distal screw 165° BDSF, 3 CLS arranged in an inverted triangle configuration, and 4 CLS arranged in a “α” configuration. Subsequently, the displacement and distribution of Von Mises stress (VMS) in the femur and internal fixation device were assessed in each fracture group under an axial load of 2100 N.ResultsAt Pauwels 30° Angle, the femur with a 150°-BDSF orientation exhibited a maximum displacement of 3.17 mm, while the femur with a 165°-BDSF orientation displayed a maximum displacement of 3.13 mm. When compared with the femoral neck fracture model characterized by a Pauwels Angle of 70°, the shear force observed in the 70° model was significantly higher than that in the 30° model. Conversely, the stability of the 30° model was significantly superior to that of the 70° model. Furthermore, in the 70° model, the BDSF group exhibited a maximum femur displacement that was lower than both the 3CCS (3.46 mm) and 4CCS (3.43 mm) thresholds.ConclusionThe biomechanical properties of the BDSF internal fixation device are superior to the other two hollow screw internal fixation devices. Correspondingly, superior biomechanical outcomes can be achieved through the implementation of distal screw insertion at an angle of 165°. Thus, the BDSF internal fixation technique can be considered as a viable closed reduction internal fixation technique for managing femoral neck fractures at varying Pauwels angles.

From ejection fraction, to myocardial strain, and myocardial work in echocardiography: Clinical impact and controversies.

Enhancing an echocardiographic tool, aimed to detect even subtle left ventricular (LV) systolic function abnormalities, capable of obtaining both early diagnosis and risk prediction of heart disease, represents an ambitious, attractive, and arduous purpose in the modern era of cardiovascular imaging. Ideally, that tool should be simple, reliable, and reproducible, in order to be concretely applied in routine clinical practice. Importantly, that technique should be physiologically plausible and useful both at the population-level, as well as in the individual subject. For a long time, LV ejection fraction (EF) has been considered the first-line parameter for assessing LV global systolic function, strictly related to the prognosis, at least in some settings. However, LV EF limitations are well-known, even though frequently overemphasized, including its load-dependency. Therefore, myocardial strain techniques have been proposed, deemed able to disclose even subtle early LV function anomalies. Nevertheless, many disadvantages of myocardial strain have been reported as well. More recently, myocardial work (MW) analysis has been introduced as a new echocardiographic tool for the evaluation of LV global systolic function, attempting to overcome EF and strain disadvantages. However, MW has shown many limits as well. Notwithstanding, LV EF still remains a landmark functional classification marker for heart failure and cardiac oncology, allowing reliable fast reassessment of LV function changes during patient management, in order to guide treatment in individual cases as well. Notably, global longitudinal strain and MW parameters seem to show better meaningful results at the population-level, but controversial clinical impact, major limitations, wide cut-offs spread and overlap, when the single value needs to be applied to the single case. Taking into account the recent literature-based evidence, the scope of the present narrative critical review is trying to delineate the different types of information given by the described LV global systolic function parameters, both at the population-level and in the individual case, in order to trace a comparative analysis of advantages and limitations in clinical practice.

The current state of the problem of soft tissue defects replacement in the lower extremities in conditions of chronic osteomyelitis

Based on the data of scientific literature, the current state of the problem of soft tissue defects replacement in the lower extremities in conditions of chronic osteomyelitis has been analyzed. Taking into account certain requirements for the replacement of defects of this nature, the following reconstructive tasks have been indicated. First of all, for adequate restoration of the skin with simultaneous relief of the purulent-necrotic process, it is necessary to use blood-supplied tissue complexes, which, if possible, should be formed from tissues similar to those surrounding the defect. The predominant use of technically and economically beneficial interventions is of great importance. The most suitable are loco-regional flaps with axial blood supply, among which the most promising are perforant flaps. It is necessary to develop an algorithm for defects reconstruction using loco-regional perforant flaps, depending on the defect area. It is also necessary to conduct a comparative analysis of the anatomical advantages and effectiveness of using various perforant and insular flaps on the vascular pedicle. A one-stage orthoplastic approach will allow the most effective use of the achievements of reconstructive plastic surgery in orthopedics to restore limb function, which will improve the results of treatment of patients.

Comparative analysis of cylindrical and planar aesa in 3d suveillance radar.

A modern rotating 3D surveillance radars scan azimuth by mechanical rotation, and scan elevation using Active Electronic Scanning Array (AESA) in Multi Beam Receive Mode (MBM). Radars with fixed cylindrical AESA and four-sided prismatic antenna, with 4 flat AESA, scan azimuth electronically, without mechanical rotation. The most significant advantage of electronic scanning is the possibility of Multi-mode operation: surveillance targets in the far zone and targeting targets in the near zone. However, electronic scanning also brings problems. A main beam of planar AESA spreads and lateral lobes increase when the radiating direction increases. An original arrangement of shifted array to reduce lateral lobes has been proposed. The cylindrical array has a constant shape of pattern during azimuth scanning. But, for both prismatic and cylindrical AESA, the beam deforms during scanning in vertical plane, so limits the elevation scan. Also, the complexity and price of fixed AESA is significantly higher compared to the rotating one. In order to enable the selection of the optimal solution for a specific application, the comparative analysis of advantages and disadvantages for cylindrical, prismatic and rotating AESA is done. The original configuration of the cylindrical AESA for Very Fast Scanning in Near-zone has been proposed.

Multilateralism in Foreign Policy of Belarus: European and Euarasian Dimension

The article builds on the author’ comparative analysis of advantages and disadvantages of regional dimensions (both towards the European Union and the CIS region) of Belarusian foreign policy in framework of multilateralism. The lack of political cooperation since 1997 didn’t affect a lot the dynamic of economic bilateral cooperation between the EU countries and Belarus (since 1995 the EU is the second trade partner for Belarus after Russian Federation). Contrary, it is growing tendency in the CIS region in certain shift from bilateralism to multilateralism in pursuing national security, political and economic interests. Multilateral regional structures, from the Commonwealth of Independent States (CIS), Eurasian Economic Union (EAEU) between Armenia, Belarus, Kazakhstan and Russian Federation (with membership of post-soviet countries) to Shanghai Cooperation Organization (SCO) with membership of Russia and China and observer status of India, Pakistan, Iran and Mongolia and status of dialogue partner for Belarus, Turkey and Shri-Lanka are gaining the power as the essential modes of regional governance, though being still different in integration priorities of member states and fragile in institutions. Existing difficulties should not overshadow gains within those organizations, nor regional dynamism in general by assuming that regional approach towards multilateral cooperation are thought to be more efficient when dealing with local, subregional and regional challenges and problems.

Comparative Analysis of Competitive Advantages of Rice Paddy and Oil Palm Farming in Mukomuko Regency, Bengkulu Province

ABSTRACT
 
 The conversion of lowland rice land to oil palm plantations has become a long debate because it is not in accordance with the vision and mission of Mukomuko Regency regarding food self-sufficiency, but in recent years there has been a change in the function of oil palm plantations to lowland rice. This is interesting to study because this phenomenon is considered unique when in other areas people flock to change the function of food land to oil palm plantations, on the other hand in Mukomuko District the community has shifted land functions from oil palm plantations to rice fields, even though so far the oil palm farming business . The location selection was carried out purposively and the determination of the respondents was carried out by the solvin method, which obtained 181 respondents. Collecting data using a survey method by distributing questionnaires to respondents. For data analysis using the private profit method and the private cost ratio. The results of the study explain private profitability and financial efficiency (private cost ratio). Where the private profitability of lowland rice (Private Profitability) is Rp. 38,173,833, - / Ut / Ha / Year - while for oil palm farming, the private profit is Rp. 28,308,303, - / Ut / Ha / Year. This means that when viewed from a private profit side, lowland rice is more competitive. However, if it is seen from the financial efficiency (Private Cost Ratio) of lowland rice farming, it is 0.31, while for oil palm farming it is 0.24 which means that the PCR values ??of lowland rice and oil palm farming are less than 1, so both of them have a level of competitive advantage and have competitiveness, when compared, the value of oil palm PCR <PCR for Paddy Paddy (024 <0.31) which means that in financial efficiency, oil palm farming is more efficient.
