The Improved Motion Model of Particles in the Cone Crusher Considering the Spatial Compound Motion of the Mantle

The cone crusher is the main equipment in the particle crushing process. The productivity of the cone crusher is determined by the motion characteristics of particles passing through the crushing chamber. In order to accurately describe the motion characteristics of the particles, the influence of the spatial compound motion of the mantle rotates around the central axis of the cone crusher and its central axis on the motion characteristics of the particles is investigated, then the improved motion model is established. Through the coordinate system transformation matrix, the motion characteristics of the particles including spatial sliding, free-falling, and spatial compound falling are solved. The applicability and accuracy of the improved model in describing the motion characteristics of the particle were verified through the experiment using a reduced-scale experimental cone crusher to simulate the motion characteristics of the particle. Based on the improved model, the motion characteristics of the particles in the CF11 hydraulic cone crusher can be simulated. With the decrease in height, the motion characteristics of particles gradually change from spatial sliding to spatial compound falling and finally to free-falling. The particles deflect circumferentially around the central axis of the cone crusher. The circumferential deflection of particles is directly related to the motion characteristics including spatial sliding and spatial compound falling. The improved model provides a theoretical basis for the high energy design of the crushing chamber and productivity improvement of the cone crusher.

Strategic planning and its relationship with the competitiveness and permanence of chinese family SMEs in Mexicali / La planeación estratégica y su relación con la competitividad y permanencia de las PYMEs familiares chinas en Mexicali

Family SMEs of Chinese origin in Mexicali, Baja California, are part of a dynamic and transcendental sector due to their participation in economic activity and development, having a favorable impact on the development of the State, having as a characteristic that the owner is the pillar and central axis of the administrative exercise, being the image as an organization, and the natural leader within, being the center of the organizational dynamics. The research is descriptive, non-experimental, cross-sectional, considering the commercial segment with a wide potential due to its ability to face problems that concern it and because it constitutes the most important sector, with the aim of identifying whether among the factors of closure and lack of consolidation of this type of companies, is the low implementation of strategic planning. The instrument applied was a questionnaire to a sample of 30 companies, the information obtained was processed and statistically analyzed. The results show that there is a considerable tendency towards resistance to investing time and effort in carrying out the design of strategic planning, concluding that actions should be generated, designed and implemented to help carry out the operation, achieving competitiveness and sustainability. permanence in the market.

Conservative Islamic factions vs. secular nationalists: toward a civil contestation in democratic Indonesia

This paper describes how Indonesia’s presidents have delt with Islamist and secular nationalist political contestation since the preparation of Indonesian independence and how the current president compares. Soekarno’s initial reliance on civil discourse ended in his autocratic decree that banned the Indonesia’s most powerful Islamic party (Masyumi). Soeharto’s initial iron-fist approach ended up meeting some Islamic demands. B.J. Habibie helped transformed Indonesia through a democratic election in 1999, but the leader of the winning party, Megawati was defeated in the parliament that elected a pluralist Muslim cleric, Gus Dur. Gus Dur’s administration, ended by the central axis, suggests that liberal democratic processes cannot be applied in an increasingly conservative Muslim majority country. Megawati lost, partly because she is a female president unpopular among the Islamists, while SBY was sympathetic toward the Islamist’s demands, enhancing the “conservative turn.” Jokowi has used discursive and legal approaches to promote Pancasila in challenging the hardline Islamic demands, enabling him to ban HTI and FPI and to implement the speech freedom-limiting laws, leading to criticisms and the decline in the 2020 Indonesia's Democracy Index. Jokowi’s expansion of these laws to maintain unity and stability may be deemed an “authoritarian turn,” but I argue that it may be more appropriately called “the Pancasila turn.” In framing and analyzing Jokowi’s laws as a Pancasila turn, I am arguing in this paper that this lays the foundation for a more equal, civil, and democratic contestation.

One Source, Two Source(s): Ribs and Tethers

We present the unique and challenging case of a radio galaxy in Abell 3266 observed as part of the MeerKAT Galaxy Cluster Legacy Survey. It has quasi-periodic bright patches along the tail which connect to never-before-seen thin transverse extensions, which we call “ribs”, reaching up to ∼50 kpc from the central axis of the tail. At a distance of ∼400 kpc from the host (assuming the z=0.0594 redshift of Abell 3266) we found what appears to be a triple source with its own apparent host at a photometric redshift of 0.78. Mysteriously, the part of the tail far from the host and the triple are connected by a series of thin filaments, which we call “tethers”. The far tail, tethers and triple also have similar spectra and Faraday rotation measures, suggesting that there is only one—quite complicated—source, with a serendipitous background AGN in the triple. We look at possible causes for the “rib” and “tether” structures, and the emerging phenomena of intracluster medium filaments associated with radio galaxies.

A New Method of Central Axis Extracting for Pore Network Modeling in Rock Engineering

Characterizing internal microscopic structures of porous media is of vital importance to simulate fluid and electric current flow. Compared to traditional rock mechanics and geophysical experiments, digital core and pore network modeling is attracting more interests as it can provide more details on rock microstructure with much less time needed. The axis extraction algorithm, which has been widely applied for pore network modeling, mainly consists of a reduction and burning algorithm. However, the commonly used methods in an axis extraction algorithm have the disadvantages of complex judgment conditions and relatively low operating efficiency, thus losing the practicality in application to large-scale pore structure simulation. In this paper, the updated algorithm proposed by Palágyi and Kuba was used to perform digital core and pore network modeling. Firstly, digital core was reconstructed by using the Markov Chain Monte Carlo (MCMC) method based on the binary images of a rock cutting plane taken from heavy oil reservoir sandstone. The digital core accuracy was verified by comparing porosity and autocorrelation function. Then, we extracted the central axis of the digital pore space and characterize structural parameters through geometric transformation technology and maximal sphere method. The obtained geometric parameters were further assigned to the corresponding nodes of pore and throat on the central axis of the constructed model. Moreover, the accuracy of the new developed pore network model was measured by comparing pore/throat parameters, curves of mercury injection, and oil-water relative permeability. The modeling results showed that the new developed method is generally effective for digital core and pore network simulation. Meanwhile, the more homogeneity of the rock, which means the stronger “representative” of binary map the rock cutting plane, the more accurate simulated results can be obtained.

Root canals shaped by nickel-titanium instrumentation with automated computerized numerical control systems

Background To investigate the efficacy of a nickel-titanium (NiTi) file with an automated computerized numerical control (CNC) system for root canal shaping. Methods The movement of the automated device and the insertion angle were investigated. In Experiment 1, simulated resin root canals were randomly divided into four groups (n = 20): manual downward movement using a handpiece (Group 1), vertical downward movement by CNC (Group 2), reciprocating up and down movement by CNC (Group 3), and spiral up and down movement by CNC (Group 4). In Experiment 2, five different insertion angles of the NiTi file were evaluated (n = 20). Four parameters were used to evaluate the shaping ability: change in the working length, central axis offset, curvature variation, and preparation time. Groups were compared using one-way analysis of variance (ANOVA) with significance was set at P < 0.05. Results The change in central axis position in the curved part of the root canal was found to be smaller in Group 4 than in other groups (P < 0.05). The curvature changes and preparation time of Groups 1 and 4 were significantly reduced compared with Groups 2 and 3 (P < 0.05). The variation in working length and curvature in the 5° insertion angle group was significantly smaller than in the other groups (P < 0.05). Conclusions A spiral up and down movement, controlled by the CNC machine, and 5° insertion angle, maintained original root canal shape more precisely than other methods.

The advancement of science and technology has modified the lifestyle, implanting superficial recreation sites away from the natural environment, education must center the student within the natural context to generate environmental awareness and form critical and reflective beings. Present real alternatives that promote interaction with the natural environment and generate meaningful learning. This article was based on qualitative research through a bibliographic review, the most relevant articles were selected, the results were obtained from indexed journals, mainly in Google Scholar. Green pedagogy aims to transform the social and cultural context by adding nature as the central axis of education; For this, various researchers present real alternatives to bring the natural environment closer to the social one, trying to contrast the damage caused to the planet. Several researchers try to generate environmental awareness, analyze the socio-historical context and present alternatives that stop the damage caused to the Earth, to produce a significant change within society, for this it is necessary to intervene in education and to shape actions, thoughts and ways of proceeding of students in a conscious, direct and real way.

Reconstructing Pure Land Buddhist Architecture in Ancient East Asia

Pure land comes from the Indian term “sukha,” which means welfare and happiness. However, in East Asia, Buddhism has been associated with the theological concepts of the immortal realm in the bond of death and afterlife. This study reviews detailed conception of Pure Land architecture in Sanskrit literature, as well as Buddhist sutras. The thesis notes that the conceptual explanation of Pure Land architecture, which describes the real world, becomes more concrete over time. Such detailed expression is revealed through the depiction of the transformation tableau. Hence, through Pure Land architecture situated on Earth, this research shows that Buddhist monks and laypeople hope for their own happy and wealthy settlement in the Pure Land. The building’s expression of transformation tableaux influences the layout and shape of Buddhist temples built in the mundane real world at that time. Moreover, this study notes that Bulguksa Monastery is a cumulative product of U-shaped central-axis arrangements with courtyards, terraced platforms, high-rise pavilions, and lotus ponds, plus an integrated synthesis of religious behaviors by votaries as a system of rituals. Further, it merges pre-Buddhist practices and other Buddhist subdivisions’ notions with Hwaeom thought, in comparison with Hojoji and Byodoin Temples that follow the Pure Land tradition.

THE HAN RIVER AS THE CENTRAL AXIS AND THE PREDOMINANCE OF WATER: QUESTIONING THE CLAIM OF “NO CHU-RELATED TRAITS” IN THE VIEW OF TERRESTRIAL SPACE IN THE RONG CHENG SHI MANUSCRIPT (FOURTH CENTURY B.C.E)

The description of the “Nine Provinces” (Jiu zhou 九州) found in the Rong Cheng shi 容成氏 (Mister Rong Cheng?, late fourth century b.c.e.) manuscript from the Shanghai Museum Bamboo Slips Collection (Shangbo cangjian 上博藏簡) is the only manuscript version of it known to date. Its discovery immediately raised the question of its relation to the cluster of descriptions on the “Nine Provinces” transmitted from the late Warring States to the early Western Han periods. There is general consensus that the manuscript description of the “Nine Provinces” has close affinity with the transmitted descriptions, as well as with a wide spectrum of transmitted early Chinese texts in general. It is distinguished by the eclectic combining of known spatial concepts, rather than manifesting any radically new or specifically Chu traits. In this study I reassess this impression with respect to the reference to the Han River in the manuscript, which up to now has been noted only in passing as an unsolved puzzle. I argue that the Han River is referred to here as the central axis that divides terrestrial space into southern and northern halves, something that implies a shifting of the mapped area to the South and thus conveys a Chu view of space. Together with philological analysis of the descriptions of terrestrial space, I apply an innovative method of investigation of these descriptions through landmarks, using as a visual aid traditional Chinese historical maps. In addition, I explore the predominance of waters as the distinguishing feature of the representation of terrestrial space in the Rong Cheng shi manuscript and demonstrate its difference from the structuring of terrestrial space proceeding from mountains to waterways to be seen in the majority of transmitted early Chinese texts.
