We formulate the thermodynamic Bethe Ansatz (TBA) equations for the closed (periodic boundary conditions) A (2) 2 quantum spin chain in an external magnetic field, in the (noncritical) regime where the anisotropy parameter η is real. In the limit η → 0, we recover the TBA equations of the antiferromagnetic su(3)-invariant chain in the fundamental representation. We solve these equations for low...

The integrals of motion of the tricritical Ising model are obtained by Thermodynamic Bethe Ansatz (TBA) equations derived from the A4 integrable lattice model. They are compared with those given by the conformal field theory leading to a unique one-to-one lattice-conformal correspondence. They can also be followed along the renormalization group flows generated by the action of the boundary fie...

One-dimensional repulsive δ-function bose system is studied. By only using the Bethe ansatz equation, n-particle partition functions are exactly calculated. From this expression for the n-particle partition function, the n-particle cluster integral is derived. The results completely agree with those of the thermal Bethe ansatz (TBA). This directly proves the validity of the TBA. The theory of p...

The quality and nutritional value for both fish protein concentrate (FPC) made from tilapia by-products as well as salt-biscuits supplemented with 5% FPC were evaluated. The resultant product (FPC) was composed (on wet weight) of 4.18% moisture, 68.83% protein content, 0.75% lipid and 25.39% ash and it was more uniform in color and texture. In addition, the pH value was 6.67 and total volatile ...

Analytical methods which are accurate to about 1 per cent have been developed for the determination of small amounts (ca. 500 gamma) of bis(beta-chloroethyl)-sulfide (H), ethyl-bis(beta-chloroethyl)amine (EBA), tris(beta-chloroethyl)amine (TBA), beta-chloroethyl-benzylsulfide (benzyl-H), and beta-chloroethyl-ethylsulfide (ethyl-H). The determinations are made by micro titration of the HCl liber...

We supplemented diets with a-tocopheryl acetate (100 mg/kg) and replaced beef tallow (BT) in feeds with increasing doses of n-6or n-3-rich vegetable fat sources (linseed and sunflower oil), and studied the effects on the fatty acid (FA) composition, the a-tocopherol (aT) content and the oxidative stability of rabbit plasma and liver. These effects were compared with those observed in a previous...

UNLABELLED Today the influence of the digestive tract functional violations followed by microaspiration of gastric contents (MAGC) on the incidence, features and outcomes of bronchopulmonary dysplasia BPD) remains little studied. Focusing on this aspect makes the research actual. OBJECTIVE determination of the nature of influence of MAGC on the progress and course of BPD. METHODS 373 newbor...

Background & Aim: Chemicals antioxidants and lipid oxidation products are known as cancer-causing factors in food systems. In this study, the effect of essential oil from Heracleum lasiopetalum fruits on lipid oxidation and physicochemical properties of potato chips in comparison with commercial antioxidant has been investigated. Experimental: The essential oil of H. lasiopetalum extracted usin...

Abstract Solid‐state fluorescent materials are in huge demand owing to their potential applications sensors, imaging, and LEDs. The molecular aggregations the solid state limit usage practical applications. Typically, J‐aggregates show enhanced emission, while H‐aggregates quenching state. Few supramolecular approaches (like creating hydrogen bonds) were developed disturb π–π other interactions...
