Os pecados capitais e a simbologia animal na prédica de Santo Antônio

O objetivo principal deste trabalho é a análise do sermão Pecados capitais e hipocrisia, simonia, detração e adulação, circunscrito no conjunto dos escritos antonianos que se reportam ao universo dos bestiários medievais. Na obra em questão, os respectivos vícios humanos são evocados, cada qual, a partir da analogia estabelecida com o comportamento de determinados animais. Santo Antônio de Lisboa (1192-1231) viveu a maior parte de sua vida durante as primeiras décadas do período conhecido como Baixa Idade Média (século XIII ao XV). Data do início dessa era o estabelecimento de uma arte de pregar medieval, que toma como referência as idéias propaladas no princípio do Cristianismo, a filosofia dos Padres da Igreja e, por fim, os diversos preceptores do século XIII, que espelhavam o novo contorno do qual havia se revestido a teoria da prédica, em que se sublinhava também a forma de pregar, até então preterida em função do conteúdo da oratória. É também nessa época que tomam vulto as ordens mendicantes, dentre as quais se destacam os franciscanos. Santo Antônio, como pregador dos Frades Menores, valeu-se dos conhecimentos adquiridos durante o período em que integrou a Ordem dos Cônegos Regrantes de Santo Agostinho; da filosofia propalada pelo fundador da Ordem instituída por São Francisco de Assis; e, por fim, de todos os artifícios que lhe oferecia a oratória de seu tempo. Dirigiu sua prédica, sobretudo, aos cátaros, hereges que desprezavam as coisas materiais, inclusive a natureza. Ao utilizar o simbolismo dos bestiários medievais, estima-se que Santo Antônio conciliou três fatores fundamentais na eficácia de seu discurso. O primeiro deles se refere à plena comunhão entre os recursos da ars praedicandi e a alegoria do bestiário medieval. Em seguida, ressalta-se a própria utilização do mundo animal como fator de eficaz eloqüência, considerando-se a concepção, em voga na sociedade medieval, de que a natureza seria um espelho codificado do universo espiritual, e nela estariam subjacentes os propósitos de Deus para com os homens. O terceiro fator a ser destacado é a harmonia entre a utilização do bestiário medieval como subsídio retórico e a filosofia dos franciscanos, que confere valor especial à natureza, sobretudo aos animais

High-current adaptive impedance matching in narrowband power-line communication systems

This paper proposes a high current impedance matching method for narrowband power-line communication (NPLC) systems. The impedance of the power-line channel is time and location variant; therefore, coupling circuitry and the channel are not usually matched. This not only results in poor signal integrity at the receiving end, but also leads to a higher transmission power requirement to secure the communication process. To offset this negative effect, a high-current adaptive impedance circuit to enable impedance matching in power-line networks is reported. The approach taken is to match the channel impedance of N-PLC systems is based on the General Impedance Converter (GIC). In order to achieve high current a special coupler in which the inductive impedance can be altered by adjusting a microcontroller controlled digital resistor is demonstrated. It is shown that the coupler works well with heavy load current in power line networks. It works in both low and high transmitting current modes, a current as high as 760 mA has been obtained. Besides, compared with other adaptive impedance couplers, the advantages include higher matching resolution and a simple control interface. Experimental results are presented to demonstrate the operation of the coupler. © 2011 IEEE.

Effects of animal and plant protein diets on growth of Indian major carp (Labeo rohita Ham.) fingerlings

An experiment was conducted with Labeo rohita fingerlings in an indoor static fish rearing water system of glass made aquaria. Five experimental diets A, B, C, D and E were formulated containing 33% dietary protein level in five treatments each having two replicates containing 12 fingerlings of mean total initial weight of 13.00±0.2g. Sixty days of feeding trial in this experiment showed that fish fed on diet 'A' containing fish meal and diet 'E' containing mixed plant sources protein had significantly highest and lowest growth respectively. However, no significant difference of growth was found in fish fed on diets C and D containing meat and bone meal, and mix of animal protein source diets respectively. The result showed that the apparent protein digestibility (APD) of diets 'A' and 'E' had significantly best and least values respectively. Food conversion ratio (FCR) and protein efficiency ratio (PER) ranged between 1.37 to 2.17 and 1.38 to 2.18 respectively. On the basis of observed FCR and PER diets 'A' and 'E' produced significantly highest and lowest growth respectively.

Prospects of integration of aquaculture with animal husbandry and land crop culture in Tripura State

Tripura is a densely populated small state with meagre water resources. 47.51% of the population is constituted by socio-economically backward, illiterate, orthodox, tribal and scheduled castes. Some of them are nomad and a majority of the rest of the population is refugees from Bangladesh, but almost 100% is fish eater. Settlement of tribes in villages, provision of nutritious food and employment therefore calls for proper utilization of every resource they have. The State is poor in water resources but recently has created 21,636.23 ha of new water area. Tripura is rich in pig population, besides poultry birds. Paddy is the main crop cultivated in arable lands. An integration of livestock raising and land based agriculture with pisciculture practices around mini barrages will help in solving the problems to a great extent. The paper is an attempt to outline the prospects of integration of aquaculture with animal husbandry and land based crop culture in Tripura State.
