h3 gourmet: not so fast food

The h3 case study focuses on the development and offer of a new chain of hamburger restaurants that began in Portugal and is spreading to other countries like Spain, Brazil and Poland. The general idea of the business venture is to grow quickly and occupy an unconventional place in the fast food burger business: a food chain with a gourmet touch, taking a high profile approach with natural ingredients, customization and quality service, where hamburgers are served on heated plates with cutlery and may be accompanied by a glass of wine, homemade lemonade or iced tea. The client can finish the meal with ice cream or chocolate coulant desserts with quality ingredients. H3 now has more than 40 restaurants; it is preparing to conquer the world and challenge the big players both in malls and street restaurants. Competitive advantages and critical success factors will play a vital role in this case

5α,6α-Ep­oxy-7-norcholestan-3β-yl acetate

The title cholestan, C28H46O3, was prepared by epoxidation of 7-norcholest-5-en-3β-yl acetate and crystallized by slow evaporation from an ethano­lic solution. All rings are trans fused. The 3β-acetate and the 17β-cholestane side chain are in equatorial positions. The mol­ecule is highly twisted due to its B-nor characteristic. A quantum chemical ab-initio Roothaan Hartree–Fock calculation of the equilibrium geometry of the isolated mol­ecule gives values for bond lengths and valency angles in close agreement with the experimental ones

Avaliação da atividade de extratos de Talinum triangulare e Sphagneticola trilobata sobre Trypanosoma cruzi.

O Trypanosoma cruzi, agente etiológico da doença de Chagas, atinge cerca de 18 milhões de pessoas na América Latina. Os fármacos utilizados para o tratamento geralmente são ineficazes e apresentam severos efeitos colaterais, tornando a busca por novos tratamentos bastante pertinente. Vários trabalhos têm mostrado os efeitos de extratos de plantas contra T. cruzi. As espécies vegetais Talinum triangulare (Portulacaceae) e Sphagneticola trilobata (Asteraceae) conhecidas popularmente no Brasil como caruru do Pará e vedélia, respectivamente, classificadas como invasoras, são mais resistentes ao ataque de pragas, despertando assim o interesse farmacológico. Assim, este trabalho avaliou os efeitos de extratos de T. triangulare e S. trilobata em culturas de T. cruzi
