The crisis of nation is caused by the crisis of inner self and moral degradations, that politic which must be oriented to safety people, but show emphasizing to individual or group orientation finally the politic, which must have service character precisely dominated and patronage character. So, it is significant to develop cognition, affection, and psicomotoric componens on a simultant scale through education. However education has antisipatoris and preparatoris characters. The identification of democaration values and provide a model through civic education will be concrete the fundamental function of education in effort to create the humanis people and shaped unresistant education to reality. So, education can cange political culture.

In this study, Hydrolysate from angelwing clam (Pholas orientalis) was produced at 0, 1, 2 and 3 hrs and E/S ratio of0.5 and 3%using alcalase where the pH and temperature were kept constant at pH 8.5 and 60°C, respectively. The hydrolysates were analysed for antioxidant and functional properties such as solubility, emulsifying properties and water and oil holding capacity. Degree of hydrolysis (DH), yield, functional and antioxidant properties were influenced by the hydrolysis time and E/S ratio. Higher enzyme concentration (E/S 3%) and longer hydrolysis time increased the DH. Yield was higher at E/S 3% but reduced with hydrolysis time. Longer hydrolysis time produced more soluble hydrolysate and higher metal chelating activity but lower in emulsifying properties and DPPH activity. Higher enzyme concentration resulted in increase only in solubility and metal chelating activity. This study revealed that enzymatic hydrolysis using alcalase should be performed at shorter hydrolysis time using intermediate concentration of enzyme (E/S between 0.5 to 3%) in order to produce angelwing clam hydrolysate with collectively good functional and antioxidant properties.

In Linguistics the terms model and modelling have a vast array of meanings, which depends on the purpose and the object, and the type of the scientific research. The article is dedicated to the investigation of a special procedure of semantic processes modelling, deducing and substantiating the notion “evolutional semantic model”, the content and operational opportunities of which differ drastically from the essence and purpose of the known from the scientific literature phenomenon of the same name. In the proposed research this variety of modelling is oriented towards the description of the dynamics of the legal terms content loading, the estimation of possible vectors of the semantic evolution on the way of its terminalization/determinalization. The evolutional model of semantics has here as its basis the succession of sememes or series of sememes, the order of which is determined with accounting of a number of parameters. The typical schemes of the meaning development, illustrated by the succession of sememes, are considered to be the models of semantic laws (evolutional semantic models = EMS). Their function is the explanation of the mechanism and the order of the stages of the semantic evolution of the system of the words which sprung from one root on the way of its legal specialization, and, therefore, the proposed in the paper experience of semantic laws modelling differs from the expertise of the “catalogue of semantic derivations”, proposed by H. A. Zaliznjak, which doesn’t have as its purpose the explanation of meaning displacements, and from the notion of semantic derivation, models of derivation, dynamic models, worked out by O. V. Paducheva, which also only state such a displacement, without proving its reality. Key words: evolutional semantic model (EMS), modelling, semantic law, sememe, pre(law).

Religious bigotry pervades our world today. As the 21st century oscillates between what Ramin Jahanbegloo (2015) has described as the politicisation of religion and its accompanying ideologisation, this study examines the vast array of literary creativity and indigenous religion/knowledge from an ecocritical viewpoint. By indigenous, it is meant those systems of knowledge and production of knowledge that are sometimes perceived as antithetical to the Western empirical systems. Encapsulated in myths and mythical wisdom, these indigenous values have at the centre of their philosophical presuppositions a symbiotic strategy that seeks to integrate man with nature. The study examines Wole Soyinka’s Death and the King’s Horseman and D.O. Fagunwa’s Adiitu Olodumare [The Mysteries of God, Olu Obafemi (trans)], in particular, and the indigenous religious/knowledge system that they reiterate, in general, as distinct from the Western monotheistic system in ontological and metaphysical terms. Also, largely because the metaphysical presupposition of Yoruba religion is essentially performance poetry in motion, a carnivalesque perspective is employed to account for the folkloric and other elements of carnival often described as ‘the feast of time, the feast of becoming, change and renewal’.

Triazine, one of the nitrogen containing heterocyclic compounds has attracted the considerable interest of researchers due to the vast array of biological properties such as anti-viral, antitumor, anti-convulsant, analgesic, antioxidant, anti-depressant, herbicidal, insecticidal, fungicidal, antibacterial and anti-inflammatory activities offered by it. Various antibacterial agents have been synthesized by researchers to curb bacterial diseases but due to rapid development in drug resistance, tolerance and side effects, there had always been a need for the synthesis of a new class of antibacterial agents that would exhibit improved pharmacological action. Therefore, this review mainly focuses on the various methods for the synthesis of triazine derivatives and their antibacterial activity.
