Stability conditions

Probiotics are defined as microorganisms that, when administered in sufficient quantities, confer a health benefit on the host. As they are very susceptible to environmental conditions, solid dosage forms are used to increase their stability. Our study focuses on preparing an oily suspension containing L. acidophilus at a laboratory scale, oriented for use in infants and children under two years of age.

This paper concerns a problem of finite-time stability for a class of linear singular large-scale systems with delays. Based on matrix transformations, Lyapunov function method combined with new estimation techniques, we derive sufficient conditions for solving the finite-time stability of the system.

This paper deals with synchronization analysis problem for a class of fractional-order neural networks with unbounded delays. Using the Lyapunov function method combined with fractional Halanay inequality, we derive a novel sufficient condition for asymptotic stability of the error system resulting in two neural networks are synchronized.

In this Masters thesis computational modelling techniques were employed to investigate iron-free apo-Lactoferrin (apo-Lf) structural conformation changes in the presence of variant temperature and pH. These conditions represent the environment most milk protein goes through in food processing and the production of food products.

The development of fruits without fertilization is known as parthenocarpy. Parthenocarpy improves the fruit quality, processing attributes, production and productivity of vegetable crops like tomato, cucumber, watermelon etc. Absence of seeds can enhances the shelf life of the fruits, allowing a better conservation, fruit set in adverse climatic conditions, early and offseason production of vegetable crops. Therefore, it is important to ensure yield stability regardless of environmental conditions.

The catalyst 7.5% NiO/TiO2 and seven samples of NiO/γ-Al2O3 with NiO content from 7.5% to 60% have been obtained and studied. Physico-chemical characteristics of the catalysts were determined by methods of Adsorption (BET), X-ray Diffraction (XRD), TemperatureProgrammed Reduction (TPR) and Hydrogen Pulse Titration. The catalytic properties of the obtained samples were investigated in the reaction of CO methanation at temperatures 180 – 220◦C and mole ratios hydrogen/carbon monoxide 25-100.

It is scientifically and industrially important 1 to clarify the stabilizing mechanism of proteases in extraordinary envi-ronments. We used subtilisins ALPI and Sendai as models to study the mechanism. Subtilisin ALPI is extremely sensitive to highly alkaline conditions, even though the enzyme is produced by alkalophilicBacillus, whereas sub-tilisin Sendai from alkalophilic Bacillusis stable under conditions of high alkalinity.

Escherichia coliproteinY (pY) binds to the small ribosomal subunit and stabilizes ribosomes against dissociation when bacteria experience environmental stress. pY inhibits trans-lationin vitro,most probably by interferingwith the binding of the aminoacyl-tRNA to the ribosomal A site. Such a translational arrest may mediate overall adaptation of cells to environmental conditions. We have determined the 3D solution structure of a 112-residue pY and have studied its backbone dynamic by NMRspectroscopy. ...

UMP-CMP kinase catalyses an important step in the phosphorylationofUTP, CTPanddCTP. It is also involved in the necessary phosphorylation by cellular kinases of nucleoside analogs used in antiviral therapies. The reactivity of human UMP-CMP kinase towards natural substrates and nucleotide analogs was reexamined. The expression of the recombinant enzyme and conditions for stability of the enzyme were improved. Substrate inhibition was observed for UMP and CMP at concentrations higher than 0.2 mM, but not for dCMP.

We have studied the stability of the histone-like, DNA-binding protein HU from the hyperthermophilic eubacteriumThermotoga maritimaand its E34D mutant by differential scanningmicrocalorimetry and CDunder acidic conditions at various concentrations within the range of 2–225lMof monomer. The thermal unfolding of both proteins is highly reversible and clearly follows a two-state dissociation/unfolding model from the folded, dimeric state to the unfolded, monomericone.
