HPLC/HRMS and GC/MS for Triacylglycerols Characterization of Tuna Fish Oils Obtained from Green Extraction
2023
Background: Fish oil is one of the most common lipidic substances that is consumed as a dietary supplement. The high omega-3 fatty acid content in fish oil is responsible for its numerous health benefits. Fish species such as mackerel, herring, tuna, and salmon are particularly rich in these lipids, which contain two essential omega-3 fatty acids, known as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Objectives: Due to the scarcity of information in the literature, this study aimed to conduct a qualitative and quantitative characterization of triglycerides (TAGs) in crude tuna fish oil using HPLC/HRMS. Fatty acid (FA) determination was also performed using GC/MS. The tuna fis…
High-Sensitivity Whispering Gallery Mode Humidity Sensor Based on Glycerol Microdroplet Volumetric Expansion
2021
We demonstrate a highly sensitive whispering gallery mode (WGM) relative humidity (RH) sensor based on a glycerol microdroplet. WGMs were excited using a 760 nm tunable semiconductor laser. We used free space coupling, which is effective when using a liquid resonator. A detailed analysis of different parameters influencing the sensor’s characteristics (sensitivity, hysteresis, resolution, stability, and temperature) is presented. The sensitivity of the sensor is one of the highest reported (2.85 nm/% RH in the range 50–70% RH with the resolution 1 × 10−4% RH). This type of humidity sensor has several advantages, such as high sensitivity, extended lifetime, good repeatability, and low cost, …
Measures of the Massive Mountain in Aleksis Kivi’s Play Kullervo
2022
The story of a prisoner inside an enormous steel mountain is embedded in Kullervo, an early Finnish tragedy by 19th-century author Aleksis Kivi. I focus here on the exceptional size of the mountain, as told by the main character, Kullervo. Although the embedded story has aroused admiration in research, the mountain’s size and form do not appear to have done so. If taken literally, and assuming the shape of a double pyramid, at a minimum, the mountain’s surface area would be between that of Earth and Uranus, a planet that Kivi was somehow aware of. The mountain’s maximum surface area and volume would greatly exceed that of the Sun. This mountain cannot be localized in the near environment of…
