DeST-OT: Alignment of Spatiotemporal Transcriptomics Data.

Spatially resolved transcriptomics (SRT) measures mRNA transcripts at thousands of locations within a tissue slice, revealing spatial variations in gene expression and distribution of cell types. In recent studies, SRT has been applied to tissue slices from multiple timepoints during the development of an organism. Alignment of this transcriptomics data can provide insights into the gene expression programs governing the growth and differentiation of cells over space and time.

Determination of sulfur content of diesel fuels and diesel fuel-like fractions of waste polymer cracking.

The element content of low and high sulfur containing diesel fuels was measured by different analytical methods: energy-dispersive X-ray fluorescent (EDXRF) and inductively coupled plasma atomic emission (ICP-OES) spectroscopy methods. Then results were compared. High sulfur containing diesel fuels were from heavy diesel engines and diesel fuel-like liquids obtained by thermal degradation of waste polymers.

Preparation and chemical characterization of high purity fluorapatite.

High purity fluorapatite (FAP) was prepared by solid state reaction, in flowing argon gas, at 1370 degrees C for 60 min. For chemical characterization of Ca(10)(PO(4))(6)F(2), the accuracy and reproducibility of different analytical methods were assessed. Methods with a good accuracy for the determination of Ca, P and F content were: titrations with EDTA for Ca determination (accuracy: -0.

Application of pressurized sample preparation methods for the analysis of steels and copper alloys.

Pressurized sample preparation devices (High Pressure Asher, Pressurized Microwave Digestion system, compared with a PTFE decomposition vessel) were used to dissolve certified metal alloy samples (steel, copper) for ICP analysis. Based on the results of the analysis it was established that both up-to-date devices can be advantageously applied to quickly and quantitatively dissolve metal alloy samples. To dissolve the samples, two different kinds of acid mixtures (A: nitric and hydrochloric acid; B: nitric and hydrochloric and sulphuric and phosphoric acid) were used.
