1. Impact of COVID-19 on Cardiothoracic Surgery: Experience of Alexandria (Egypt) Main University Hospital
ABSTRACT Introduction: The current coronavirus pandemic has greatly strained the limited resources that had previously maintained the sustainability of the high-cost cardiothoracic surgeries in low-income countries like Egypt. Methods: Hospital databases and patients’ records were reviewed to evaluate the impact of the pandemic on the workflow and waitin

2. COST OF AERIAL AND GROUND SPRAYINGS AND TECHNOLOGICAL REPLACEMENT POINT: A CASE STUDY IN THE REGION OF MINEIROS, GO, BRAZIL
ABSTRACT One of the main costs in agriculture is related to mechanized operations, which, in turn, are associated with the capital invested in machinery and equipment, the scale of production, and the operating efficiency. Thus, the choice of technology to carry out these operations must take these factors into account to minimize the production cost. In thi

3. A statistical solution for cost estimation in oil well drilling
Abstract Drilling operations must be preceded by adequate planning, fulfilling the path to produce hydrocarbons at low and competitive costs. Conventional well planning is based on the personal experience of project engineers, which use information from offset wells to estimate the performances in future wells. This article reviews and discusses a published

4. Optimum mine production rate based on price uncertainty
Abstract The production rate of a mining operation has an important effect on the operational cycle and gross profit, which are often evaluated based on engineering practices. Assessment of the economic performance of mine operations in mining engineering is of great importance because an incorrect production rate can result in significant financial losses.

6. Developing a stepwise approach to simulate a hammer mill through the Whiten model - the adherence for a gold ore
Abstract Comminution represents a large portion of the capital and operating cost of a mineral processing plant. In 1983, Cohen estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to reduction of t

7. A decision-making method to assess the benefits of a semi-mobile in-pit crushing and conveying alternative during the early stages of a mining project
Abstract A significant cost in the operating budget of most mining operations arises from purchasing and maintaining haulage trucks. Recently, in-pit crushing and conveying (IPCC) has been subject to research because of its potential to reduce haulage costs. The objective of this study is to identify early on in a project, by means of a decision-making metho

8. Understanding The Organizational Barriers of Promoting Electronic Delivery Options in The United States Healthcare System: An Insurer’s Perspective
ABSTRACT Consumer-driven technologies are rapidly transforming how industries conduct business both internally and externally. From online banking to retail, the broad adoption of smart devices, internet access, and wearables amongst consumers has shifted the way enterprises develop software and conduct information technology (IT) operations. Although succes

9. A COMBINATION OF DISCRETE EVENT SIMULATION AND MULTI-CRITERIA ANALYSIS TO CONFIGURE SUGARCANE DROP AND HOOK DELIVERY SYSTEMS
ABSTRACT This article explores decision analysis regarding Drop and Hook (D&H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&H systems.

10. The measurement of social impact and opportunities for research in business administration
Abstract In the last decades, management scholars have examined ways through which firms can build profitable operations while at the same time addressing pressing social and environmental concerns. But how can organizations ascertain whether their isolated or collaborative efforts are truly generating positive impact to their target populations? Measuring r

11. A new cement slurry modified with chitosan/alginate interpenetrating networks and hydroxyapatite - structural characteristics after long-term contact with hyper-saline produced water from oil well operations
ABSTRACT Oil is an important source of energy, mainly in developing countries. Important research has been conducted to find cementing procedures that guarantee safe and cost-effective oil exploration below pre-salt layers. This work aimed to make a new cement paste with cement, seawater, silica, biopolymers (chitosan and sodium alginate) and hydroxyapatite

12. Surface Integrity Analysis in Machining of Hardened AISI 4140 Steel
This study aimed to analyze the residual stresses and roughness in finishing milling of AISI 4140 steel, quenched and tempered up to hardness of 58 HRC. Machining operations were performed with the use of CBN inserts and by varying three basic cutting parameters (cutting speed, feed per tooth and cutting depth). Hardened materials are typically machined by a
