OBJECTIVE The effects of coronary perivascular adipose tissue (PVAT) on vasomotor tone are influenced by an obese phenotype and are distinct from other adipose tissue depots. The purpose of this investigation was to examine the effects of lean and obese coronary PVAT on end-effector mechanisms of coronary vasodilation and to identify potential factors involved. APPROACH AND RESULTS Hematoxyli...
Managers seeking to improve lead-time performance are challenged by how to balance resources and investments between process improvement achieved through lean/justin-time (JIT) practices and information technology (IT) deployment. However, extant literature provides little guidance on this question. Motivated by both practical importance and lack of academic research, this article examines empi...
Non-alcoholic fatty liver disease (NAFLD) is commonly diagnosed in obese subjects; however, it is not rare among lean individuals. Given the absence of traditional risk factors, it tends to remain under-recognised. The metabolic profiles of lean NAFLD patients are frequently comparable to those of obese NAFLD patients. Though results from several studies have been mixed, it has been generally r...
BACKGROUND Age-related sarcopenia may cause physical dysfunction. We investigated the involvement of sarcopenia in dropped head syndrome (DHS). METHODS Our study subjects were ten elderly women with idiopathic DHS (mean age 75.1 years, range 55-89). Twenty age- and sex-matched volunteers (mean age 73.0, range 58-83) served as controls. We used a bioelectrical impedance analyzer (BIA) to analy...
Lean production has lead to substantial improvements in performance across many industries and is widely implemented today. Certain aspects of lean such as the focus on workplace organisation (5S) and total productive maintenance (TPM) have been applied to all types of industrial processes, while lean production control methods have mostly been applied in discrete and repetitive, assembly-type ...
In the last few decades, lean techniques have been developed for removing with waste in manufacturing. More recently, lean is used outside the manufacturing context as well. This article focuses on using lean thinking for reducing waste in administrative services, i.e., business services with information as input and output. This article delivers three innovations in this field: 1) a lean appro...
One of the ultimate targets of lean manufacturing paradigm is to balance production and produce at takt time in production cells. This paper investigates the performance of a lean cell that implements the previous lean goals under uncertainty. The investigation is based on a system dynamics approach to model a dynamic lean cell. Backlog is used as a performance metric that reflects the cell’s r...
Lean production (or lean management respectively) gained popularity in several waves. The last three decades have been filled with numerous attempts to apply these concepts in companies. However, this has only been partially successful. The roots of lean production can be traced back to Toyota’s just-in-time production. This concept, which according to Womack’s, Jones’ and Roos’ research at MIT...
