PURPOSE: This study discusses the use of parameterization within the life cycle inventory (LCI) in the wooden pallet sector, in order to test the effectiveness of LCI parametric models to calculate the environmental impacts of similar products. Starting from a single case study, the objectives of...
To understand the true ecological impact and sustainability of a car, it must be viewed in the context of its whole life cycle. Read more about it
The invisible lever behind these claims is a type of study, called a life-cycle assessment, or LCA. It is a method of analysis that has evolved over the past 60 years to give corporate strategists and policy makers the ability to make sustainability decisions by measuring the environmental im...

On these numerical reasoning tests, you'll be given partial numerical data that you'll need to calculate in order to find missing data. Then, based on the data you've found, you'll need to tweak blank graphs accordingly. This SHL numerical assessment requires excellent math skills and a qu...
To first calculate manufacturing life-cycle costs, we created a bill of materials, enhanced with additional geometrical information, and then calculated the costs of some custom-made inductors, transformers, and mechanical components, such as heat sinks. For printed circuit boards (PCB...
How to Calculate DSO? To calculate DSO, divide the total accounts receivable for a given period by the total credit sales for the same period, and multiply the result by the number of days in the period. Days Sales Outstanding = (Accounts Receivable/Net Credit Sa...
Formula to calculate ROI There are originally two methods to calculate ROI First method: ROI= (Cost of Investment / Net Return on Investment) ×100% For example, ROI= (Cost of Investment / Net Return on Investment) ×100% ...
根据Fetal diagnosis and therapy上的文献的报道,判断孕胎儿的周数的重要指标是crown rump length 检称CRL--- 即头臀长或者胚芽大小, 妊娠49~56天的中位数是大于10mm的,所以当检测的要求是妊娠周数大于7周时,宝宝的头臀长需要大于10mm去接受检测才是对受测者最大的保障。 胚胎...
