UV-visible spectroscopy responds to electronic transitions involving pi and lone pair orbitals and is used to identify conjugated systems which tend to have stronger absorption. There is no single light source for the entire UV and visible region, with tungsten lamps used for the visible region and deuterium lamps for the ultraviolet region. Samples are typically held in quartz due to absorption of UV by glass, while solvents must be transparent in the region being observed and commonly lack conjugated systems or carbonyls. UV-visible spectroscopy can be used in the oils industry to detect trans isomers, determine purity, and estimate components like oryzanol, gossypol, and chlorophyll.

Newer microwave-assisted and enzymatic routes are discussed along with supercritical methanol which requires no catalyst.
Single cell oil production
Single cell oils (SCOs) are oils extracted from microorganisms like algae, bacteria, and yeast. SCOs can serve as raw materials for oleochemical industries and be sources of nutrients. Researchers expressed an inulase gene in the yeast Yarrowia lipolytica to produce oil from inulin-containing materials. The recombinant yeast was able to accumulate 46.3% oil by weight when grown on inulin, converting around 10.7% of the sugar to cell oil which was composed primarily of fatty acids like palmitic acid, oleic acid, and stearic acid. Further research aims to improve oil yield by modifying additional genes in the lipid biosynthesis pathway.

Fragrances in soap
The role of fragrance in soaps depends on whether the soap is opaque or transparent. Opaque soaps have a stronger initial scent that fades quicker, while transparent soaps use milder fragrances that maintain integrity longer. Transparent soaps also allow for more fragrance variety and longevity. Factors like cost, longevity, consumer acceptance, stability, and packaging must be considered. Fragrances can solubilize within the soap or partition between areas. Instability can cause discoloration from factors like light, temperature, pH, and iron presence during production. Different fragrances are prone to different types of discoloration.
High performance(pressure
This document discusses high performance liquid chromatography (HPLC) for analyzing oils and fats. It explains that HPLC involves separating components based on how they are distributed between a liquid mobile phase and solid stationary phase. There are two main types of mobile phases used: isocratic elution with a fixed composition and flow rate, and gradient elution where the composition and flow rate change over time to improve separation. Reverse phase HPLC is most commonly used for oil and fat analysis, where nonpolar stationary phases are used and hydrophilic compounds elute more quickly than hydrophobic compounds.
Mass spectroscopy
GC-MS involves using gas chromatography to separate compounds in a sample which are then ionized and fragmented in a mass spectrometer. The mass spectrometer detects the fragments based on their mass to charge ratio, producing a spectrum that identifies the compound. GC-MS is useful for detecting contaminants from spoilage or adulteration in samples. Sometimes an additional mass spectrometer is used, known as GC-MS-MS, to further fragment ions for more accurate identification of compounds that have similar retention times on GC.
Thin layer chromatography
Thin layer chromatography (TLC) is a simple, inexpensive technique used to separate and identify components in organic compounds. In TLC, compounds are distributed between a stationary phase, like silica gel, and a mobile phase, like a solvent or solvent mixture. As the mobile phase travels up the plate, different components travel at different rates depending on their solubility, allowing separation. Common adsorbents and solvent systems used for lipid separation are described. Various detection reagents can be used to visualize separated components under UV light or by producing colored spots. Examples are given of separations achieved for different lipid classes and subclasses using TLC.

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
