Seismic assessment and rehabilitation of a historical theatre based on a macro-element strategy

The structural and seismic assessment of the 19th-century Petruzzelli theater in Bari (Italy) is presented. The macro-elements strategy was adopted to dismantle the whole structure in parts. The steel dome was verified through dynamic multi-modal analysis based on finite element model. Each masonry macro-element was firstly verified through a kinematic analysis aiming at excluding local collapse mechanisms. Afterwards, a nonlinear static analysis was carried out in order to evaluate its overall seismic capacity. The effectiveness of linear or nonlinear analyses and of the macro-element strategy compared with other modeling techniques is also discussed. After highlighting the structural deficiencies of the theater, upgrading solutions are proposed with consideration of the safety needs and the architectural preservation requirements based on the historical importance of the buildin

Determination of the Ileal Digestibility of Proteins and Amino Acids from Biscuit Bran and Wheat Gluten in Swine

To determine the apparent (AIDCP) and standardized (SIDCP) ileal digestibility coefficients of the protein and the apparent (AIDAA) and standardized (SIDAA) ileal digestibility coefficients of amino acids from biscuit bran and wheat gluten were used six castrated males swine in growth, on average weight from 22 to 60kg, with a T cannula on the terminal ileum, distributed in a randomized block design with three treatments, two periods and two repetitions per period. Each animal was considered a repeat. Treatments consisted of a protein free diet (PFD) for determination of the endogenous loss, PFD + biscuit bran (BB) and PFD + wheat gluten (WG). Each period lasted for six days, five days of adaptation of animals to the diet and 24 hours of collection of ileal digestion. The AIDCP of BB and WG were 82.33 and 90.07%, respectively and the SIDCP of BB and WG were 89.17% and 95.60%, respectively. The SIDAA were on average 80.84% (lysine), 83.94% (threonine), 90.57% (methionine + cystine) and 87.15% (valine) to BB. The SIDAA for the WG were on average 91.01% (lysine), 90.97% (threonine), 95.82% (methionine + cystine) and 90.04% (valine). The SID of protein and essential amino acids and non-essential elements identified in this study were on average, respectively, 89.17%, 88.54% and 89.20% of biscuit branand 95.60%, 93.71% and 89.20% of wheat gluten

Ensaio de competição entre cultivares de sorgo granífero para região sudeste de Minas Gerais.

O sorgo granífero é uma das culturas que vêm apresentando significativo aumento de produtividade e área plantada no Brasil, por isso surge à importância de melhores cultivares para o mercado. O trabalho teve o objetivo de avaliar a produtividade de grãos de 25 híbridos de sorgo granífero, sendo 22 provenientes do programa de melhoramento genético da Embrapa Milho e Sorgo e três cultivares comerciais, em um experimento no delineamento em blocos ao acaso com três repetições, avaliados na Estação Experimental da Embrapa Milho e Sorgo em Sete Lagoas/MG. Para a avaliação estatística, foi realizada a análise de variância e teste F no programa Genes, e para a realização de agrupamento de médias, foi realizado o teste de Scott & Knott (1974). De acordo com as avaliações, os genótipos 0987014 e 0987028 apresentaram desempenho superior na maioria dos caracteres avaliados, se destacaram e poderão ser recomendados para o cultivo na região sudeste do Estado de Minas Gerais, após validação de seu valor de cultivo e uso em mais locais e anos

A mild and efficient method for the preparation of 3-(2'-Aminoaryl)pyrazoles from 4-chloroquinolines

We describe a mild and efficient method for the formation of 3-(2'-aminoaryl)pyrazoles in excellent yields from reactions of 4-chloroquinolines with hydrazine. These heterocyclic ring opening reactions occur under much milder conditions then previously described
