This paper is toward the categorical study of deterministic lattice-valued ([Formula: see text]-valued) fuzzy automata and deterministic quantale-valued ([Formula: see text]-valued) fuzzy automata. The existence of initial and final objects in the subcategory of category of deterministic lattice-valued fuzzy automata is shown. We also show that there is an adjunction between the category of deterministic lattice-valued and quantale-valued fuzzy automata.

We introduce and study the categorical concepts such as product, equalizer and their duals in this category. Finally, we establish a construction of a minimal fuzzy automaton for a given fuzzy language in a categorical framework. The construction of such fuzzy automaton is based on derivative of a given fuzzy language.

The sample is annealed at 500 °C in order to remove the moisture and other organic impurities. The sample is characterized by using XRD and FESEM to find out the phase and surface morphology. The observed particle size is found almost 80 nm with spherical agglomerated shape. Upconversion spectra are recorded at room temperature using 976 nm diode laser excitation sources and consequently the emission peaks in green and red region are observed. The color coordinate diagram shows the results that the present material may be applicable in different light emitting sources.

Twenty growing goat kids were randomly assigned to receive ad libitum rice straw and berseem hay (Trifolium alexandrinum L.) (40:60). Group I was fed concentrate mixture (0.1 kg/d). Group II was supplemented with UMMB (0.2kg/d). The experiment lasted for 90 days. There was significant (p<0.05) decrease in serum sodium (60.68mEq/L), increase in serum potassium (34.50 mEq/L) and increase in activity of Aspartate aminotransferase (340.42U/L) and Alanine aminotransferase (164.96 U/L) which were observed in kids of group II in comparision to the control (group I). On histopathological examination mild degenerative changes in kidney of group II with congestion in intertubular vessel, granular cytoplasm of the epithelial cells in proximal convoluted tubules (PCT) and distal convoluted tubules (DCT), necrosis and swelling of the epithelial cell...

Direct and indirect effects of these factors on frost injury vis a vis their interdependence were found to be in support ot the ‘palisade thickness method’ for screening frost resistant genotypes in potato breeding programmes.
