A review on homogeneous and heterogeneous catalytic microalgal lipid extraction and transesterification for biofuel production
PublicationExtracting lipids from microalgal biomass presents significant potential as a cost-effective approach for clean energy generation. This can be achieved through the chemical conversion of lipids to produce fatty acid methyl esters via transesterification. The extraction mainly involves free fatty acids, phospholipids, and triglycerides, and requires less energy, making it an attractive option for satisfying the growing demand for...

Microbiological corossion of metallic products as a result of biofilm
PublicationWarunkiem do pojawienia się korozji mikrobiologicznej jest utworzenie na powierzchni metalu biofilmu. Zawiera on biologicznie czynne mikroorganizmy wraz z produktami ich przemian metabolicznych. Biofilm ogranicza dyfuzję produktów metabolizmu wytwarzanych przez poszczególne komórki mikrokolonii. Powoduje to, że produkty uboczne tych przemian gromadzą się w bezpośrednim sąsiedztwie metalu. Gdy powierzchnia metalu nie jest odporna...

Macromodels in the frequency domain analysis of microwave resonators.
PublicationW artykule zaprezentowana jest technika włączania makromodeli do metod siatkowych sformułowanych w dziedzinie częstotliwości.W odróżnieniu do poprzednich, nowy schemat nie wprowadza zależności częstotliwościowej do macierzy systemowej i dzięki temu może być użyta w analizie rezonatorów. Testy numeryczne pokazują wzrost dokładności obliczeń w szerokim zakresie częstotliwości, przy czym właściwości zbieżności iteracyjnego algorytmu...

Modelling of Diffusing Capacity Measurement Results in Lung Microangiopathy Patients. A novel Diagnostic Suppport
PublicationLung microangiopathy is a little known negative influence of diabetes mellitus on the functioning of the lungs. The aim of this study is to design a supportive method for diagnosing lung microangiopathy. This will be based on routinely performed pulmonary measurements as well as on investigation process modelling and data processing. A model of the diffusion of oxygen from the alveoli to the blood has been described with a set...

The usefulness of Toxoplasma gondii MIC1-MAG1-SAG1 chimeric antigen in the serodiagnosis of ovine toxoplasmosis
PublicationToxoplasmosis is a zoonotic disease caused by the protozoan Toxoplasma gondii, which infects humans and most warm-blooded animals throughout the world. Although human toxoplasmosis in healthy adults is usually asymptomatic, a serious disease can occur in the case of congenital infection and immunocompromised individuals. Among food animals, sheep, along with goats and pigs, possess the highest incidence of T. gondii cysts in meat,...

Modeling the Influence of Salts on the Critical Micelle Concentration of Ionic Surfactants
PublicationWe show for the first time that a phenomenological, augmented volume-based thermodynamics (aVBT) model is capable to predict the critical micelle concentrations of ionic surfactants, including ionic liquids, with added salts. The model also adjusts for the type of salt added by including its molecular volume, which might form a connection to the Hofmeister effect. The other physico-chemically relevant quantities included in the...

Solubilization of tetrachloroethylene and dichlorobenzene in micellar solutions of nonionic surfactants
PublicationZbadano solubilizację tetrachloroetylenu i dichlorobenzenu w roztworach surfaktantów niejonowych (oksyetylenowanych alkoholi tłuszczowych i alkilofenoli). Określono wpływ HLB badanych związków powierzchniowo czynnych na efektywność solubilizacji zanieczyszczeń organicznych. Największą efektywność solubilizacji tetrachloroetylenu zaobserwowano dla Rokafenolu N8. W przypadku dichlorobenzenu solubilizacja przebiegała najefektywniej...

Microbiota-derived metabolites in colorectal cancer patients in preoperative period
PublicationShort-chain fat-ty acids (SCFAs) are microbial derived metabo-lites, which have multiple beneficial properties. The amount of SCFAs depends on several fac-tors, such as age, diet (mainly intake of dietary fiber), and overall health condition. The normal proportion between SCFAs is 3:1:1 for acetate, proprionate and butyrate, respectively. In col-orectal cancer (CRC) patients, microbiota alter-ations have been shown. Consequently,...

Microwave Ring Resonator Based Pressure Sensor
PublicationThis paper demonstrates a microwave pressure sensor, which is based on microstrip line-fed ring resonators. The first ring resonator is loaded with the concentric cylindrical shafts, while the same number of the hollow shanks as the shafts are mounted on the second ring resonator. The arrangement of the cylindrical shaft and hollow shank allows for mechanical movement between two substrates while maintaining electrical contact....

Perfectly Wetting Mixtures of Surfactants from Renewable Resources: The Interaction and Synergistic Effects on Adsorption and Micellization
PublicationThis paper presents a study of the surface properties of mixtures of surfactants originating from renewable sources, i.e., alkylpolyglucoside (APG), ethoxylated fatty alcohol (AE), and sodium soap (Na soap). The main objective was to optimize the surfactant ratio which produces the highest wetting properties during the analysis of the solution of the individual surfactants, twoand three-component mixtures, and at different pH values....

Atomic Force Microscope data post-processing algorithm for higher harmonics imaging
PublicationPrevious works have proved that higher harmonics topography imaging using atomic force microscope (AFM) can significantly enhanced its measurement capabilities. Integrated tools dedicated to most of microscopes allow to visualize the investigated surface only by one selected harmonic. Because of the different characteristics of a sample, scanning tip and the environment, appropriate harmonic selection is time consuming and requires...
