Aggregation is one of the many important processes in chemical and process engineering. Several researchers have attempted to understand this complex process in fluidized beds using the macro-model of population balance equations （PBEs）. The aggregation kernel is an effective parameter in PBEs, and is defined as the product of the aggregation efficiency and collision frequency functions. Attempts to derive this kernel have taken different approaches, including theoretical, experimental, and empirical techniques. The present paper calculates the aggregation kernel using micro-model computer simulations, i.e., a discrete particle model. We simulate the micro-model without aggregation for various initial conditions, and observe that the collision frequency function is in good agreement with the shear kernel. We then simulate the micro-model with aggregation and calculate the aggregation efficiency rate.

AIM: To examine patients' perceptions on communication surrounding the cancellation of orthopaedic operations and to identify areas for improvement in ***: A prospective survey was undertaken at a university teaching hospital within the department of Trauma and Orthopaedics. Patients admitted to an acute orthopaedic unit, whose operations were cancelled, were surveyed to assess patient satisfaction and preferences for notification of cancellation of their operations. Patients with an abbreviated mental test score of < 9, patients unable to complete the survey independently, those under 16 years of age, and any patient notified of the cancellation by any of the authors were excluded from this study. Patients were surveyed themorning after their operation had been cancelled thus ensuring that every opportunity was given for the medical staff to discuss the cancellation with the patient. The survey included questions on whether or not patients were notified of the cancellation of their surgery, the qualifications of the person discussing the cancellation, and patient preferences on the process. Satisfaction was assessed via 5-point Likert scale ***: Sixty-five consecutive patients had their operations cancelled on 75 occasions. Fifty-four point seven percent of the patients who had cancellations were notified by a nurse and 32% by a doctor. No formal communication occurred for 13.3% cancellations and no explanation was provided for a further 16%. Patients reported that they were dissatisfied with the explanation provided for 36 of the 75(48%) cancellations. Of those patients who were dissatisfied, 25(69.4%) were notified by a nurse. Twenty-three of the 24(96%) patients notified by a doctor were satisfied with the explanation and that communication. Of those patients who were notified by a nurse 83% patients reported that they would have preferred it if a doctor had discussed the cancellation with them. There was a significant difference

Newton considered three-dimensional universe endowed with flat space Euclidean geometry, and treated the time as an outside parameter and established his dynamics of the universe. Einstein along with space, considered time, and generated a four-dimensional universe endowed with non-Euclidean curved space-time geometry with time as its fourth dimension, and set up his field equations. Schwarzschild solved Einstein’s field equations around a star in space, which is, otherwise, flat, and obtained a solution. We, along with space and time, considered mass which also included energy according to Einstein’s mass-energy equivalence relation: E = mc2, and generated a five-dimensional universe with the mass as its fifth dimension, and solved the Einstein’s field equations, in some simple cases, and obtained solutions around a star in space, which is otherwise, flat.

Alcohol is the most commonly used and abused drug in the world, and alcohol use disorders pose a tremendousburden to healthcare systems around the world. The lifetime prevalence of alcohol abuse in the United States is estimated to be around 18%, and the economic consequences of these disorders are staggering. Studies on hospitalized patients demonstrate that about one in four patients admitted to critical care units will have alcohol-related issues, and unhealthy alcohol consumption is responsible for numerous clinical problems encountered in intensive care unit(ICU) settings. Patients with alcohol use disorders are not only predisposed to developing withdrawal syndromes and other conditions that often require intensive care, they also experience a considerably higher rate of complications, longer ICU and hospital length of stay, greater resource utilization, and significantly increased mortality compared to similar critically ill patients who do not abuse alcohol. Specific disorders seen in the critical care setting that are impacted by alcohol abuse include delirium, pneumonia, acute respiratory distress syndrome, sepsis, gastrointestinal hemorrhage, trauma, and burn injuries. Despite the substantial burden of alcoholinduced disease in these settings, critical care providers often fail to identify individuals with alcohol use disorders, which can have significant implications for this vulnerable population and delay important clinical interventions.
