Objective: identify predictors of planned discharge to night care embracement in a Psychosocial Care Center Alcohol and Drugs (CAPS AD III). Methods: Quantitative, retrospective, and documentary study of 560 medical records of people with problems resulting from the use of alcohol and other drugs who were admitted to the hospital at night in a CAPS AD III in São Paulo, over five years. As a dependent variable, the type of discharge was used (planned or not). As independent variables, the profile of the subjects related to substance use and time in hospital. Results: 1,097 admissions were identified with 50.4% of unplanned discharge associated with homelessness (p = 0.007), problematic use crack (p = 0.015), length of reception proposed by the team (p = 0.029) and length of stay of the user (p < 0.001). Conclusion: Being homeless, problematic use of crack, and lack of user participation on the decisions regarding length of stay in CAPS AD III were associated with unplanned discharge.

ABSTRACT Objectives: to analyze the scientific evidence available in literature on hospital indicators after implementation of bed regulation strategies. Methods: this is an integrative review conducted with studies available in five databases and in the reference database of the Center for Study and Research in Nursing Services Management in October 2019. Articles on hospital bed management, available in full in English, Spanish or Portuguese, without temporal delimitation were included. Results: 1,118 eligible articles were found, of which 37 were duplicated. Among 1,081 pre-selected studies, 112 studies were eligible and 11 articles were included. Six studies addressed the emergency services. Three addressed hospital indicators in general, another focused on a psychiatric ward and one analyzed the indicators of two hospitals administered differently. Conclusions: the studies focused on emergency services, demonstrating the importance of organizing these services for health institutions.

I have recently been analyzing campaign photos - including medical images of infants - so I draw on these specifics to explore certain bodies' ability to elicit moral emotions. The poem's narrative, however, places engagements with this digital "place" into the context of wider material landscapes of social media use. [Extracted from the article]

We propose an IoT suppo1t system for estimating the posture of the care recipient on the bed from the body pressure of the care recipient measured by a sheet-type body pressure sensor, and detecting the posture related to leaving the bed in real time. In addition, we propose a method that predicts getting out of the bed before the care recipient takes a posture related to getting out of the bed by considering the state transition. Intervention experiment showed that using body pressure features as an explanatory variable and applying machine leaming, 16 types of postures on the bed of care recipients with an F value of 0.7 or more could be identified. From the experiment without intervention, by applying the hidden Markov model, we calculated the transition probability to each hidden state when the care recipient getting out of the bed and the transition probability to each hidden state when the care recipient not getting out of the bed. As a result, there was a difference of about 0.1 in the transition probability of the state related to raising upper body. [ABSTRACT FROM AUTHOR]

The bacteria that colonize humans and our built environments have the potential to influence our health. Microbial communities associated with seven families and their homes over 6 weeks were assessed, including three families that moved their home. Microbial communities differed substantially among homes, and the home microbiome was largely sourced from humans. The microbiota in each home were identifiable by family. Network analysis identified humans as the primary bacterial vector, and a Bayesian method significantly matched individuals to their dwellings. Draft genomes of potential human pathogens observed on a kitchen counter could be matched to the hands of occupants. After a house move, the microbial community in the new house rapidly converged on the microbial community of the occupants' former house, suggesting rapid colonization by the family's microbiota.

Abstract Background The recent increase in knee arthroplasty (KA) use in Korea is among the highest in the world. The rapid increase in KA use suggests that the KA use in Korea could have been affected by medically unjustifiable factors. This study aimed to examine the geographic variation in the rate of KA and its associated factors in Korea. Methods We used the data from the National Health Insurance in Korea in 2013, from which a total of 67,086 claims for KA were obtained. We calculated the age-sex-standardized KA rates of the entire population and the crude rates of the age groups 0–64 and 65 and over in 251 districts. We assessed the geographic variation of the KA rates and examined the associated factors with a multivariate linear regression with the KA rate as a dependent variable. Results The overall rate of KA in Korea was 132.7 per 100,000 persons. The rates of KA showed a four-fold variation. The deprivation index score and the number of beds in the small to medium sized hospitals showed a positive association with the rates of KA while the number of orthopedic surgeons showed a negative association. Conclusions Korea has been experiencing a rapid increase in the use of KA for the last decade or so, which was most prominent among the elderly population aged 65 and older. Our results suggest that the higher rate of KA is strongly related to a higher supply of beds and the socioeconomically deprived conditions. Considering that the decision concerning KA has room for discretion and also affects a considerable portion of health care expenditures, the use of KA should be thoroughly monitored with more emphasis on standardization in the decision making process and preventive measures that can lessen the need for KA.

Abstract Background Ambulatory care sensitive conditions (ACSC) hospitalization is a widely accepted measure of the access to primary care. However, given its discretionary characteristics, the ACSC hospitalization can be a measure reflecting the influence of hospital bed supply. In Korea, where the quality of primary care and oversupply of hospital beds are coexistent concerns, ACSC hospitalization can be used to examine the impact of both factors. This study was performed to investigate the ACSC hospitalization rate as a measure of the hospital bed supply as well as access to primary care. Methods Data were obtained from the National Health Insurance Database for 2015. We calculated the age-sex standardized hospitalization rates for ACSC in the total population and crude rates of ACSC hospitalization for three different age groups in 252 districts in Korea. We calculated the variation statistics of ACSC hospitalization rates, and we estimated a linear regression model to investigate the factors for ACSC hospitalization. Results There was a very high geographic variation in ACSC hospitalization rates. Higher density of primary care physicians was associated with a decreased ACSC hospitalization rate while a higher density of hospital beds in small to medium sized hospitals was associated with an increased rate. The deprivation index score had a strongly positive association with the ACSC hospitalization rates. Conclusion ACSC hospitalization, while being a negative index of primary care access, can also be a measure indicating the impact of the hospital bed supply, and it is still a valid measure of the disparity of health care, the original motivation for this topic.

This work is devoted to a numerical study of inflow swirl on the flow field in a spouted bed. The Eulerian-Eulerian multiphase model was used to simulate the hydrodynamics of a gas-solid flow in a 2D axisymmetric spouted bed under an unsteady laminar regime. The results of the simulations are validated with the experimental data obtained by He et al. (Can. J. Chem. Eng. Vol. 72, pp. 229–234 and pp. 561–568, 1994). The comparison of the results shows that the numerically obtained profiles of the time-averaged axial solid velocity agree well with the experimentally measured values. The results of the simulations revealed that the slightly increase in the swirling ratio of the inlet flow leads to an enhanced spouting process, while a strong swirling ratio has an adverse effect on the mixing between gas and solid particles. Thus, the use of the inflow swirl enables control of dynamics of spouted beds.

Fluid dynamic characterization for a set of three serial rectangular based spouted beds (RBSB) using sawdust or turnip seeds, were made. In batch experiences, the minimum spouting velocity (U ms) and the maximum pressure drop (Δ P max) were determined based on the bed height and moisture content. With respect to the continuous solid feed experiences, initially the conditions that allowed the stationary operation for 1, 2 and 3 beds connected in series, were determined. Following, injecting colored particles and with an image analysis it was possible to determine the residence time distribution (RTD). When compared with expressions from literature, good agreement was found for U ms , whereas for Δ P max an expression is proposed that includes the sphericity of the particles. The RTDs were adjusted with the tank in series model, finding that the effects of solids feed rate, air flow and moisture content are significant for each solid RTD. Unlabelled Image • Determination of fluid dynamic parameters and adjustment of a proposed correlation. • RTD for sawdust and turnip seeds determined experimentally through image processing. • Effect of operational variables of sawdust on its mean residence times. • Effect of the number of RBSB connected in series on the RTD was determined.

Neonatal units should be organized as a progressive care line, with intermediate and intensive care beds (conventional and kangaroo). The aim of this study was to evaluate the status and adequacy of neonatal beds in maternity hospitals linked to the 'Stork Network' ("Rede Cegonha"). A descriptive study was conducted in 606 maternity hospitals in all regions of Brazil. The databases used belonged to the Stork Network Evaluation Survey and the National Live Birth System. To assess the distribution of neonatal beds by typology, the parameters proposed in Ordinance N. 930/2012 of the Ministry of Health were used. Most neonatal units are not organized as a progressive care line with the three types of bed planned. Kangaroo intermediate care beds comprise the minority of implanted beds. There is a concentration of intensive and intermediate beds in the Southeast and South regions, which show a kangaroo intermediate care bed deficit. Analyzing the adequacy of beds by the number of live births, one can observe an inadequacy of Kangaroo care beds in all regions of Brazil, as well as intensive bed deficit in the North and Northeast regions, and adequacy of conventional intermediate care beds in all regions.

Interest in the production of USDA-certified organic tobacco continues to increase. Limited research exists that focuses on organic production practices specific to tobacco. Float beds, a semi-hydroponic system, are commonly used to germinate seed and produce healthy transplants. High bicarbonate concentrations in the float bed solution are a common issue and can greatly affect seedling health. A greenhouse experiment was conducted to evaluate OMRI-certified acidifier treatments for their effects on float bed media and solution nutrient status and plant health. Treatments included acetic acid, liquid citric acid, granular citric acid, a sulfuric acid conventional check, and stagnant and aerated controls. Miniature float beds were constructed to which the acidifier treatments were applied, each containing a single 288-cell tray and fertilized with seabird guano. The aerator treatment was the only one to consistently maintain bicarbonate levels below the recommended 100 mg L−1. Aeration also created an environment that favored high nitrate and low ammonium concentrations compared to all other treatments. Dissolved oxygen remained at or above 6 mg L−1 with aeration, while the remaining five treatments resulted in concentrations below 4 mg L−1. No significant differences were found among the acidifier treatments for percent of usable transplants produced. Media selection may play a role in buffering the extreme bicarbonate concentrations, as the pH in the media tended to be lower than the more alkaline solution. The use of an aerator proved to be an effective means to manage high bicarbonate and appears to promote higher rates of nitrification of the organic fertilizer source material.

Sludge drying beds may be classified into five main types: conventional sand drying bed (CSDB), paved drying bed (PDB), wedge-wire, vacuum assisted, and solar drying bed. In this research, three configurations of PDBs were investigated experimentally in order to determine the best configuration by using drainage pipe placed in different locations in the basin, covered by geo-textile membrane and fine gravel filter. The best configuration of modified PDBs was compared with the CSDB. The effect of sludge layer height (30, 50, and 72 cm) and sludge types (waste activated sludge (WAS), thickened combined primary and waste activated sludge (CPAS), primary sludge and trickling filter humus) on the performance of modified PDB have been also studied. The results showed that using two pipes in the PDB; one in the bottom channel of the tank and the other in the corner of the tank is the best configuration that achieved a higher drainage water ratio in shorter drying time. The maximum dried solid content achieved by the CSDB was 16% after 12 d of drying, whereas the same solid content was achieved by the modified PDB after only 3.5 d of drying and the solid content increased to 47% after 12 d of drying. The results also showed that the best sludge layer height is 50 cm where the maximum dried solid content achieved by the modified PDB was 52% after 12 d of drying. The WAS and the thickened CPAS have the highest dried sludge solid content which was about 52%, 55% compared to the other types for 12 d of drying time. The modified PDB achieved the highest solid loading rate (598 kg/m² y) to obtain 20% dried solid content compared to the conventional PDB (191 kg/m² y) and conventional sand drying bed (225 kg/m² y).

A spouted bed containing non-spherical particles was investigated numerically using the non-spherical discrete hard-sphere method, and experimentally using particle image velocimetry. The experimental and simulated particle velocity distributions were in agreement. Different operating conditions were used to investigate the instability of the spouted bed. Certain conditions created an S-shaped gas channel in the center of the bed, which proved the instability of non-spherical particles. The motion of micro-scale particles and bubbles was studied to determine their potential relationship with instability. It was found that the granular temperature distribution of the particles and bubbles was associated with the gas channel region. The behaviors of bubbles differed from those of particles. These results contribute to an understanding of instability mechanisms in spouted beds. Unlabelled Image • Experiment based on PIV system was conducted for non-spherical particles. • Non-spherical particle behaviors were simulated by DPM. • Instability phenomenon was studied in spouted bed with non-spherical particles.

Premise of research. Fossil fruits and seeds of Zingiberales provide essential data on the past diversity and distribution of the order, augmenting our understanding of the evolutionary history of gingers, bananas, and relatives. Methodology. Three different types of zingiberalean fruits and seeds from the Late Cretaceous–early Cenozoic Deccan Intertrappean beds of central India were studied using physical sections, polished slices, peels, and micro–computed tomography scanning. A morphology-based phylogenetic analysis was conducted to assess the fossils' phylogenetic position within Zingiberales. Pivotal results. Fruits and seeds of "Musa" cardiosperma Jain were reevaluated, and newly collected specimens indicate that this species was common and widely distributed across central India during the late Maastrichtian. Morphological differences indicate that they do not conform to the extant genus Musa but instead represent an extinct genus of Zingiberaceae for which the name Momordiocarpon R.N. Deshmukh & Kokate has priority. Seeds of Momordiocarpon cardiospermum (R.K. Jain) comb. nov. lack the micropylar collar found in extant Musaceae and have only a weakly defined oblique chalazal chamber. Orthogonospermum patanense gen. et sp. nov. is recognized based on seeds from the Maastrichtian of Marai Patan. These seeds are rectangular, with 90° corners in transverse and sagittal sections, and are obovate in coronal section. Both Momordiocarpon and Orthogonospermum have massively thickened seed coats in the hilar region, unlike any extant Zingiberales. Phylogenetic analyses place Momordiocarpon and Orthogonospermum in Zingiberaceae. Callistemonites indicus Bande, Mehrotra & Prakash, known from fruits with intact seeds from the Paleocene of Ghughua, is here shown to represent a taxon distinct from M. cardiospermum ; its original binomial is reinstated. Conclusions. Together, these three species add to the known diversity of the Late Cretaceous and early Cenozoic of India. Two of these species are confirmed to be in Zingiberaceae, enhancing our understanding of the early diversification and biogeographic spread of Zingiberales. [ABSTRACT FROM AUTHOR]

At present, the sludge drying beds of the Kyiv wastewater treatment plants are operated as a sludge accumulator in an emergency mode, practically without free volume. The purpose of the work was to determine the equation for the evaporation losses calculation from sludge drying beds and the required free volume for sludge accumulation for the next 7 years. The required free volume was calculated using the water budget method which takes into account evaporation from the water surface and evapotranspiration during the vegetation. The total losses from sludge drying beds is 1076 mm/year in normal year and is 920 mm/year in a cold year. The required free volume was calculated considering the trend of increasing average temperature over the last decade and considering the significant environmental risk. A correction was made for one unfavourable year with cold summer and warm winter and an additional rain rate of 1% probability. The additional free volume required is 3.24 million m3 for 7 years if all three sludge drying beds are operated. [ABSTRACT FROM AUTHOR]

Objective: The primary objective was to determine the clinical benefit of using a specific alternating-pressure mattress overlay (APMO) in the prevention of pressure ulcer (PU) in patients at medium to high risk. Method: This prospective study was conducted in five rehabilitation centres and three nursing homes. Patients at medium to high risk of PU, but without PU at baseline, and lying between 15 and 20 hours per day on a specific APMO were included. The primary endpoint was the percentage of patients who developed a sacral, spine, heel or trochanteric PU (supine support areas) of at least category II, at day 35. All patients were included in the analysis. Results: A total of 89 patients were included; of whom six patients (6.7%) dropped out of the study (average (±standard deviation) follow-up 32±5.4 days). No sacral, spine, heel or trochanteric PU of at least category II was reported (i.e., an incidence of 0% [95% Confidence Interval: 0–4.1%] according to the exact Clopper–Pearson method]. Patients were 'satisfied' or 'very satisfied' with the comfort and stability of the APMO. The caregivers assessed as 'very easy' or 'easy' the implementation, maintenance and use of the APMO (turning over, moving to a sitting position). Conclusion: In combination with the usual measures to prevent PU, the results of our study showed a low incidence of PU in high-risk patients lying for between 15 and 20 hours a day on an APMO, use of which is therefore recommended in these patients.

This paper puts forward a decision model for allocation of intensive care unit (ICU) beds under scarce resources in healthcare systems during the COVID-19 pandemic. The model is built upon a portfolio selection approach under the concepts of the Utility Theory. A binary integer optimization model is developed in order to find the best allocation for ICU beds, considering candidate patients with suspected/confirmed COVID-19. Experts' subjective knowledge and prior probabilities are considered to estimate the input data for the proposed model, considering the particular aspects of the decision problem. Since the chances of survival of patients in several scenarios may not be precisely defined due to the inherent subjectivity of such kinds of information, the proposed model works based on imprecise information provided by users. A Monte-Carlo simulation is performed to build a recommendation, and a robustness index is computed for each alternative according to its performance as evidenced by the results of the simulation.

This work is motivated by the lack of a model for the splash function associated with the collision of wind-blown sand grains onto an inclined granular surface. This splash function, which describes the velocity of rebound particles and the number and velocity of ejected particles, is an essential ingredient of theoretical models of sand transport and the formation of dunes and ripples. While previous models regarded the granular bed as a horizontal surface, there is experimental evidence that bed slopes can affect the splash process. However, since it is difficult to investigate particle trajectories near the bed from experiments, numerical simulations that resolve individual particle trajectories provide useful means to elucidate the effect of bed slope on the splash function. Here we employ numerical simulations by means of the Discrete-Element-Method (DEM) to investigate the splash function of sand-sized particles impacting onto inclined beds. To this end, we consider bed slopes consistent with those of the windward side of ripples and dunes. Specifically, the angle θ between the granular bed and the horizontal is varied from 0° to 15°, while a broad range of particle impact velocities (from 1 m/s to 7 m/s) is considered. Moreover, we consider values of incident particle diameter d in within the range 120 ≤ d in /μm ≤ 520, i.e., consistent with natural sand. We obtain expressions for all parameters of the splash function as a function of the incident particle diameter and velocity, and the bed slope. In particular, our simulations show that the effect of the bed slope on the splash function depends on the size of the impacting particle, which has implication for grain trajectories formative of ripples and dunes. Unlabelled Image • Rebound angle decreases with the size of the incident particle and the bed slope. • The number of ejecta increases linearly with the momentum of incident particle. • Ejecta velocity increases slightly with the momentum of the incident particle. • Ejecta angle increases slightly with the bed slope. • Coefficient of restitution is influenced by the size of the incident particle.

• CFD simulations of the heat transfer in fully resolved packed beds • Up to 619 particles and more than 2000 contact points • A correction of the effective thermal conductivity of bridges is suggested • Simulation error could be reduced by up to 75% In recent years, computational fluid dynamic (CFD) simulation of fully resolved fixed beds has become a popular tool for getting deeper insight in local phenomena in packed beds. To get correct simulation results, special care has to be taken on how to treat particle/particle and particle/wall contact points. In this work a local contact point modification, the local bridges method is investigated to study its effect on the heat transfer in packed beds. Packings were created using the Discrete Element Method (DEM) software discrete Flow, and were modified to implement the bridges. Using Design of Simulation Experiments (DoSE) the influence of different parameters on the heat transfer was studied. The simulated heat transfer in packed beds, considering conduction as well as natural convection, is compared to measurements and well-established correlations. Based on the Design of Simulation Experiments, a model for the correction of the effective thermal conductivity of bridges, to reduce the simulation error as a function of particle diameter D, is suggested. The suggested correction was tested on spheres of different material and sizes to check its validity. Using this correction, the simulation error for the beds surface temperature could be reduced by 75 % in a representative example case. [ABSTRACT FROM AUTHOR]

The Miocene genus Rzehakia, an endemic brackish bivalve that lived in the Paratethys Sea, recorded in late Ottnangian sediments deposited during the regression of the Central Paratethys Sea in the semi-enclosed Alpine-Carpathian foreland basin, is closely related to the Rzehakia found hundreds of kilometres away in the early Badenian transgressive sequence situated in the Western Carpathians hinterland. The finding of the "Rzehakia beds" from the Malý Krtíš site in the Novohrad-Nógrád Basin provides insight into the palaeobiogeography of the Central Paratethys. The present study documents Rzehakia-bearing deposits of an alternating wave-dominated, river-influenced environment and of a fluvial-dominated, tide-influenced, wave-affected environment, probably located on the prodelta slope of a compound deltaic clinoform. Corresponding calcareous nannofossil assemblages, marked by the absence of Sphenolithus belemnos and the co-occurrence of Helicosphaera ampliaperta with Sphenolithus heteromorphus without Helicosphaera waltrans, indicate the NN4 Zone. Furthermore, the presence of the regional benthic foraminiferal marker Uvigerina graciliformis indicates a Karpatian age and the planktic Globorotalia transsylvanica restricts the profile stratigraphic range to the upper Burdigalian-Langhian part of the NN4 Zone (i.e., upper Karpatian-lower Badenian). In accordance with updated palaeogeographic data, these results led us to the conclusion that the "Rzehakia beds" in the Novohrad-Nógrád Basin are synchronous with or younger than those from the Alpine-Carpathian Foredeep and are possibly related with their middle Miocene (late Kotzakhurian–early Tarkhanian) occurrences in the Eastern Paratethys.

Brachiopod shell accumulations are abundant and diverse in the lower Cambrian strata of Yunnan Province, South China, but most commonly they are composed of linguloid and acrotheloid brachiopods. Here, we describe the first record of shell beds with high-density accumulations of microscopic acrotretoid brachiopods (usually <2 mm in width) in the muddy deposits of the Wulongqing Formation (Guanshan Biota, Cambrian Stage 4) in the Wuding area of Yunnan Province. The acrotretoid shell beds from the Wulongqing Formation vary from thin mm-thick pavements to more well-developed beds, several centimeters thick. The occurrence of remarkably rich acrotretoid shell beds indicates that microscopic lingulates began to exert an important role in hardening and paving the soft-substrate seafloor during the early Cambrian evolution of Phanerozoic "mixgrounds." The new Guanshan material is referred to a new species, Linnarssonia sapushanensis n. sp., which differs from other species of Linnarssonia mainly in having a well-developed internal pedicle tube, as well as a relatively longer dorsal median septum. The occurrence of Linnarssonia sapushanensis n. sp. in the Wulongqing Formation in eastern Yunnan extend the oldest record of the genus on the Yangtze Platform of South China back to at least Cambrian Stage 4.

This paper presents a new method that is able to define the hydraulic jump peculiarities in rough-bed conditions. The findings of this paper improve the literature and guidelines on the design of a stilling basin over a rough bed, taking into account both the Froude number and bottom roughness. It starts with experimental evidence on the flow field and considers the characteristic length scale of the phenomenon as drawn from velocity measurements in the hydraulic jump region. The assumption in the length scale leads to different results compared with the known formulas in the literature related to the hydraulic jump on a rough bed. The formulas in the literature consider the effects of gravel roughness only, neglecting the effects due to the incident Froude number in the evaluation of integrated bottom shear stress. The comparison of the presented results with experimental measurements in the literature highlights the reliability and accuracy of this novel method. This method is theoretically based, but because it needs experimental data in application, it can be considered semiempirical. The results presented here allow for the design of hydraulic jump stilling basins over rough beds. [ABSTRACT FROM AUTHOR]

Trans literature, in the context of American literature, is traditionally linked to the autobiographical genre. However, there is currently an uprising of trans-author voices that are also manifesting themselves in the narrative genre, more specifically, in the short story. The short stories "Large Animals", and "Together", by Jess Arndt, present similar elements about the discomfort of what it means to be socially read as a trans subject and a trans body departing from animal otherness, which manifests itself in the inconvenient presence of an intestinal parasite in the protagonist couple of "Together" and in a walrus paying night visits to the bed of the protagonist of "Large Animals". We will seek to bring together the elements of trans identity and animal otherness that appear in Arndt's narratives with Donna Haraway's proposals (2016a; 2016b) for the interspecies alliance and the union between past, present and future, which she calls the Chthulocene, as a form to overcome Anthropo/Capitalocene and the specters of modernity.

The present work is carried out to study the performance of a Savonius rotor for small-scale hydropower generation. It has been observed that some of the irrigation channels available in the rural areas are having enough bed slope to generate kinetic energy, which can be harnessed through a Savonius rotor. An in-house fabricated scale-down model of the Savonius rotor is tested at an inclination of the re-circulating indoor multipurpose tilting flume at 0°, 0.5°, 1.0°, 1.5° and 2.0° to determine performance under controlled conditions. It is observed that at the tip speed ratio of 0.92 and channel inclination of 0.5° compared to 0° inclination, the coefficient of power and coefficient of torque improved to 40% and 10%, respectively. Furthermore, it is found that the torque and power developed by the turbine are maximum at a bed slope of 2.0° owing to the maximum available energy. • C P and C T increased due to the increase in kinetic energy and tip speed ratio for bed slope 0.5° when compared to 0° • P Available in the channel is more compare to power developed by the rotor for 1°, 1.5° and 2° bed slope inclination • Froude number (Fr) reached supercritical value for θ = 1.5° and 2° bed slope • The torque and power developed by the turbine is increases with respect to bedslope (θ) [ABSTRACT FROM AUTHOR]

The effects of an immersed tube on slugging fluidization and particle behaviors in slugging fluidized beds were investigated using computational fluid dynamics. Both shallow and deep slugging fluidized beds with and without an immersed tube were simulated using the two-fluid model. The presence of an immersed tube gave rise to regions of high voidage below the tube and regions of low voidage above the tube. Formation of the high voidage region occurred by particle deflection away from the immersed tube, while that of the low voidage region resulted from particle vortices above the tube. The presence of an immersed tube was observed to facilitate bubble formation and bubble coalescence in both shallow and deep slugging fluidized beds. In shallow beds, an immersed tube regularized pressure fluctuations but increased the amplitude of fluctuations. In deep beds, an immersed tube reduced the frequency of pressure fluctuations by facilitating wall slug formation. Based on random sampling and statistical testing (Z-test) of mean slug lengths, it was concluded that mean slug lengths increased when U was increased from 0.90 m/s to 1.0 m/s in the deep free column (p-value = 0.0422). Based on an F-test of the slug length variance, it was concluded that there was larger variability of slug lengths for U of 1.0 m/s than for U of 0.90 m/s in the deep free column (p-value = 0.0202). However, the results of these statistical tests on mean slug lengths and slug length variance for the deep single tube column showed that U had no significant effect on mean slug length or slug length variance at the 5% significance level. Thus, one of the effects of an immersed tube in a deep slugging fluidized bed was regulation of the size of slugs formed and prevention of any significant increase in mean slug size or slug size variability.
