This document describes a single-laboratory validation study of a combustion method for determining total sulfur content in fertilizers. The method involves combusting samples at 1150°C, converting sulfur species to SO2, and measuring SO2 levels using a thermal conductivity detector. Eleven fertilizer samples with sulfur content ranging from 1.47-91% were analyzed over multiple days. Recoveries ranged from 94.3-125.9% and precision was good, suggesting the method is accurate and precise for determining total sulfur in fertilizers. Further collaborative study is recommended to validate the method.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
