Die Methode stellt ein effizientes Extraktionsverfahren auf der Grundlage der Fl ssig-Fl ssig-Extraktion (LLE) dar, das eine hohe und konsistente Wiederfindung f r beide Analyten erm glicht. Der Matrixeffekt wurde gr ndlich bewertet, indem die IS-normalisierten Matrixfaktoren auch durch Infusion des Analyten nach der S ule gesch tzt wurden. Die entwickelte LC-MS/MS-Methode f r die Quantifizierung von ART, DHA, LF und DLF in menschlichem Plasma wurde gem den Richtlinien der US FDA vollst ndig validiert. Die vorgeschlagene Methode ist f r beide Analyten empfindlich im Vergleich zu allen anderen Methoden, die entweder als Einzelanalyt oder in Kombination in verschiedenen biologischen Matrices vorgestellt wurden. Die Methode bietet im Vergleich zu den bisher vorgestellten Methoden erhebliche Vorteile in Bezug auf den geringeren Probenbedarf f r die Analyse, die Einfachheit des Extraktionsverfahrens und die Gesamtanalysezeit. Die Abwesenheit von Matrixinterferenzen wird durch die Nachs uleninfusion und durch die Pr zisionswerte (% CV) f r die berechneten Steigungen der Kalibrierkurven effektiv nachgewiesen. Die validierte Methode zeigte akzeptable Daten f r alle Validierungsparameter mit angemessener Empfindlichkeit und Selektivit t f r ihre gleichzeitige Quantifizierung in einem klinischen Umfeld.

Il metodo presenta una procedura di estrazione efficiente basata sull'estrazione liquido-liquido (LLE) che fornisce un recupero elevato e costante per entrambi gli analiti. L'effetto matrice stato accuratamente valutato stimando i fattori di matrice normalizzati IS anche attraverso l'infusione dell'analita dopo la colonna. Il metodo LC-MS/MS sviluppato per la quantificazione di ART, DHA, LF e DLF nel plasma umano stato completamente validato secondo le linee guida della FDA statunitense. Il metodo proposto sensibile per entrambi gli analiti rispetto a tutti gli altri metodi presentati sia come singolo analita che in combinazione in diverse matrici biologiche. Il metodo offre vantaggi significativi rispetto a quelli precedentemente riportati, in termini di minore necessit di campioni per l'analisi, semplicit della procedura di estrazione e tempo complessivo di analisi. L'assenza di interferenze della matrice efficacemente dimostrata dall'infusione postcolonna e dai valori di precisione (% CV) per le pendenze calcolate delle curve di calibrazione. Il metodo validato ha mostrato dati accettabili per tutti i parametri di validazione, con sensibilit e selettivit adeguate per la loro quantificazione simultanea in ambito clinico.

Concrete structures and the associated cracking represent a persistent challenge within the fields of construction and civil engineering, a dilemma that has persisted for decades. Generally, cracks arise from the expansion and contraction of materials, which can lead to various forms of damage within buildings. Engineers typically address these damages and irregularities through manual inspections or by employing predictive models developed using machine learning techniques, thereby facilitating a comprehensive assessment of the structural health of the edifices. This research aims to implement tools such as the VGG 16 network model alongside other machine learning methodologies to identifycracks in concrete structures. We propose a model that integrates Convolutional Neural Networks (CNN) with a VGG-based architecture. For image processing and segmentation, we have employed the gradient boosting algorithm. The datasets utilized in this study were sourced from the Kaggle platform, and the Hugging Face Transformers library was leveraged for implementation. To assess the performance of the developed models, metrics including precision, accuracy, recall, and F1 score were employed.

Modern lifestyle has initiated a vegan diet through the uptrend in plant-based or non-diary milk that is subsequently incorporated in Ice cream making. The aim of the study was to formulate a coconut milk-based Ice cream using natural sugars i.e., Palm Date (Phoenix dactylifera L.) as an alternative to conventional ice cream and to compare and evaluate its physicochemical characteristics and sensory attributes with the conventional ice cream. The present study was undertaken with different proportions of date pulp and American sweet corn milk. The product obtained was analysed for sensory attributes (colour, texture, flavour, appearance, overall acceptability) using 9point Hedonic scale. Analysis of Rheological properties and Physico-chemical properties were done on formulated ice cream. The results showed that the formulated ice cream can be served as an alternative for vegans, those who are lactose intolerant, sensitive to milk proteins (casein) those who prefer vegan ice cream due to dietary and ethical factors.
