Gest?o & Regionalidade , 2008,
Abstract: O problema a ser tratado no artigo é “como as subsidiárias estrangeiras de empresas multinacionais brasileiras avaliam o ambiente externo nos países em que atuam? ”Além disso, qual a influência do ambiente competitivo na cria o de valor das subsidiárias de multinacionais brasileiras? O objetivo é diagnosticar os atributos da perspectiva ambiental, identificar quais s o importantes e sugerir estratégias para as empresas. Foram analisadas por survey 66 subsidiárias em 22 países, divididos entre membros da OCDE (42%) e, posteriormente, regionais (45%). O Modelo Diamante, de Porter, e a Teoria das Multinacionais Regionais, de Rugman, foram usados como referencial teórico. As inferências estatísticas embasaramos seguintes resultados: existe uma avalia o diferenciada e mais positiva do ambiente competitivo para as subsidiárias localizadas em países da OCDE e em países distantes geograficamente do Brasil; existe associa o entre o ambiente externo e a cria o de valor no exterior, sendo que o dos países-membros da OCDE é mais forte e positivo para as competências de inova o (P&D), ao passo que o ambiente externo de subsidiárias regionais ou em países n o-membros da OCDE é mais fraco, o que n o sustenta a forma o de cria o de valor.

Abstract: between february 1984 and march 1992, 10 patients with aortic coarctation undetwent surgical correction with the technique of subclavian aortoplasty with preservation of arterial flow to the left upper limb. eight of the patients were male and 2 were female. their ages ranged from 2 months to 25 years (mean 6.3 years) and the weight ranged from 3.1 to 60 kg (mean 21.2 kg). surgical technique basically consisted of detachment of the left subclavian artery with subsequent reimplant as a ceiling over the constricted aortic area, thus preserving the arterial flow to the left arm. in this procedure two steps are fundamental: a) wide dissection of aorta and the left subclavian artery in order to allow full mobilization of those vessels, and b) anterior aortic incision should be large to allow reimplant of the subclavian proximal flap well beyond the constricted area. this will produce a wide anatomic reconstruction without tension on the suture lines. two modifications of the original technique have been utilized: a) resection of a segment of anterior aortic wall the base of the subclavian artery. this will allow a good aortoplasty for patients with well formed isthmus with less dislodgement of the original subclavian insertion, and b) resection of the coarcted segment, end to end anastomosis of the posterior wall and anterior widening with the previously detached and posteriorly incised subclavian artery. this modification is best indicated for small children since it will remove the adjacent ductal tissue. the original technique was utilized for three patients; the modification with and anterior aortic flap was employed in 2 patients and the technique with simultaneous resection of the coarcted area was utilized in the other 5 patients. there was a single operative death, not related to the technique. nine patients were followed for 1 to 8 years post-operatively (mean 3.9 years). all patients remained asymptomatic, with normal arterial blood pressure and normal pulses i

Abstract: the effect of antimicrobial (a) replacement with dehydrated egg (de) and of type of litter (new and recycled) used in the floor covering on pullet performance was evaluated in 1,440 1-d chicks, 720 of each strain (white and brown), allotted to 72 boxes (1 x 1.5 m). recycled litter consisted of sugar cane bagasse containing droppings of broilers chicks with symptoms of coccidiose. the pullets were weighed and assigned to a complete randomized design with a 3 x 2 x 2 (three diets x two litter x two strains) factorial arrangement, in a total of 12 treatments with six replications of 20 pullets. the experimental diets (d) were: d1 = diet with commercial dose of antimicrobial; d2 = diet without antimicrobial; and d3 = diet without antimicrobial + 0.6% of de. de was composed by dehydrated yolk+albumen (55°c for 72 hours) and showed negative result to samonella spp. test. the use of recycled litter decreased pullet performance of two genetic groups, specially the brown ones, that showed lower weights of spleen and bursa of fabricius. this fact suggests better enlargement of lymphoid tissues, and that probably explains the smaller tolerance of white pullets to recycled litter. the antimicrobials minimize negative effect of recycled litter on pullet performance. dehydrated egg is a good alternative to antimicrobials and can improve performance of pullets in the pre-starter on conventional environment.
