Perancangan dan Analisis Aliran Udara Sistem Ducting Cloud Kitchen dengan Metode Computational Fluid Dynamics

Cloud Kitchen is a commercial kitchen that serves food for delivery or takeaway without dine-in customers. Because the cloud kitchen consists of many kitchens, good air circulation is needed. The total volume of the 15 kitchen units in the cloud kitchen is 249.8 m3, so to meet commercial kitchen standards that have a minimum Air Change per Hour (ACH) value of 30 ACH, an air change of 4410 m3/h with a ducting system is required. From the simulation results, the air velocity distribution in the ducting ranges from 0 m/s to 92.426 m/s, while the pressure distribution in the ducting ranges from -578.824 Pa to 11639.58 Pa, and the distribution of air temperature in the ducting ranges from 49.8°C to 65.167°C. The chosen exhaust fan is a CKE brand centrifugal fan with type CKE DGB-4.5#-NO and an exhaust capacity of 5712–10562 m3/h

Economic freedom and the impact of technology on productivity

A well-developed body of literature has detected positive effects of technology investments on economic growth. We contribute to this literature by studying the joint effects of technology and economic freedom on economic growth. Using two different time points. 1990 and2000. and a sample of over 100 countries. we find that economic freedom enhances the effect of technology on economic growth. In fact, we find that the standalone effect of freedom is not as large as its interactive effect with technology

California Micro Devices Corp.: A Class Discussion Of Auditors Ethical, Legal, And Professional Responsibilities

This short case is best for an open discussion in an upper-division auditing class. The class discussion questions intensify students learning experience on (1) auditors ethical responsibility to resolve tough ethical issues, (2) auditors legal responsibility to detect fraudulent financial reporting, and (3) auditors professional responsibility to conform to auditing standards. Additional class discussion questions, optional hands-on internet experience, and class discussion guide are provided. The case illustrates how a high-technology company succumbed to the pressure of unrealistic financial goals in an industry that is characterized by rapid technology change, intense competitive pressure, and volatile demand patterns for computer chips. High-level management at the company orchestrated fraudulent financial reporting schemes by creating fictitious sales and shipping bogus inventories. The fraud was uncovered only after the companys Board of Directors appointed a third auditor to investigate the sophisticated fraudulent schemes. However, the action came a little too late as the shareholders began to file class-action securities lawsuits against the company and its former auditor

A Simple Photometer Based on a New Tri-Colour Light-Emitting Diode

Light-emitting diodes which can produce blue, green, and red light and therefore cover most of the visible range have recently been introduced. Such a device is used in the construction of a simple and compact photometer for molecular absorbance measurements in analytical chemistry

SourceAmerica Design Challenge Accessible Kitting and Packaging Station

This document entails our research, design, proposed development, and testing process for solving the 2020 SourceAmerica collegiate design challenge. Our team, “Just Kitting”, is composed of four Mechanical Engineering students from California Polytechnic San Luis Obispo. The design challenge requires us to create a device that will help improve the quality of life and productivity of people with disabilities working in the kitting and packaging industry. This document includes our background research and information received from various interviews with our sponsor and others who have experience working with disabilities. Using this information, we refined our problem statement to focus on individuals with disabilities that affect their fine motor skills because many procedures in the kitting and packaging industry are heavily reliant on the dexterity of the user. We tailored our ideation process, decision matrices, concept prototypes, and design justification around this target demographic. This process resulted in the final design of our workstation which provides an innovate and efficient way to bag and package five types of items. In addition, this design requires simple push-pull motions to reduce the dexterity required to create a kit. We have outlined our manufacturing and design verification plans to proceed with this design, along with a breakdown of our projected costs to implement a functional prototype

Characteristics of Adults Who Use Prayer as an Alternative Therapy

Purpose: To describe the demographics, health-related and preventive-health behaviors, health status, and health care charges of adults who do and do not pray for health. Design: Cross-sectional survey with 1-year follow-up. Setting: A Minnesota health plan. Subjects: A stratified random sample of 5107 members age 40 and over with analysis based on 4404 survey respondents (86%). Measures: Survey data included health risks, health practices, use of preventive health services, satisfaction with care, and use of alternative therapies. Health care charges were obtained from administrative data. Results: Overall, 47.2% of study subjects reported that they pray for health, and 90.3% of these believed prayer improved their health. After adjustment for demographics, those who pray had significantly less smoking and alcohol use and more preventive care visits, influenza immunizations, vegetable intake, satisfaction with care, and social support and were more likely to have a regular primary care provider. Rates of functional impairment, depressive symptoms, chronic diseases, and total health care charges were not related to prayer. Conclusions: Those who pray had more favorable health-related behaviors, preventive service use, and satisfaction with care. Discussion of prayer could help guide customization of clinical care. Research that examines the effect of prayer on health status should adjust for variables related both to use of prayer and to health status

Brief Screening of Vascular Cognitive Impairment in Patients With Cerebral Autosomal-Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy Without Dementia.

BACKGROUND AND PURPOSE: Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a monogenic form of cerebral small vessel disease leading to early-onset stroke and dementia, with younger patients frequently showing subclinical deficits in cognition. At present, there are no targeted cognitive screening measures for this population. However, the Brief Memory and Executive Test (BMET) and the Montreal Cognitive Assessment (MoCA) have shown utility in detecting cognitive impairment in sporadic small vessel disease. This study assesses the BMET and the MoCA as clinical tools for detecting mild cognitive deficits in CADASIL. METHODS: Sixty-six prospectively recruited patients with CADASIL, and 66 matched controls completed the BMET, with a subset of these also completing the MoCA. Receiver operating characteristic curves were calculated to examine the sensitivity and specificity of clinical cutoffs for the detection of vascular cognitive impairment and reduced activities of daily living. RESULTS: Patients with CADASIL showed more cognitive impairment overall and were poorer on both executive/processing and memory indices of the BMET relative to controls. The BMET showed good accuracy in predicting vascular cognitive impairment (85% sensitivity and 84% specificity) and impaired instrumental activities of daily living (92% sensitivity and 77% specificity). The MoCA also showed good predictive validity for vascular cognitive impairment (80% sensitivity and 78% specificity) and instrumental activities of daily living (75% sensitivity and 76% specificity). The most important background predictor of vascular cognitive impairment was a history of stroke. CONCLUSIONS: The results indicate that the BMET and the MoCA are clinically useful and sensitive screening measures for early cognitive impairment in patients with CADASIL.Stroke Association (Grant ID: TSA2008/10), British Heart Foundation (Grant ID: PG/13/30/30005), Stroke Association/British Heart Foundation (Grant ID: TSA BHF 2010/01), Agency for Science, Technology and Research, Singapore, National Institute for Health Research (Senior Investigator award), Cambridge University Hospital Comprehensive National Institute for Health Research Biomedical Research UnitThis is the final version of the article.
