Influence of genetic group and feeding on performance of lambs in confinement
O objetivo deste trabalho foi estabelecer a influĂŞncia do reprodutor e da alimentação sobre o desempenho de cordeiros em confinamento. O delineamento experimental foi o inteiramente casualizado, com arranjo fatorial 2x4, costituĂdo de dois grupos genĂ©ticos (Santa InĂŞs x sem raça definida (SRD) e Somalis x SRD) e concentrado de milho em gĂŁo, farelo de soja e sal mineral a 15%, 30%, 45% e 60%. Trinta e dois animais foram confinados em baias individuais e cada um constituiu uma repetição. As dietas eram compostas de feno de leucena (Leucaena leucocephala) e concentrado, na forma de ração completa. O aumento de concentrado na dieta dos animais causou incrementos lineares (P 0,05) entre os concentrados, porĂ©m o grupo genĂ©tico Somalis x SRD mostrou-se superior (P 0.05) among concentrates; however, the genetic group Somalis x NDB was superior (P < 0.05) to Santa InĂŞs x NDB
Dissimilar Sequelae Caused by Single Dental Trauma; A Case Report with Long-Term Follow-Up
Immediate care and accurate diagnosis are essential for treating dental trauma. This report presents a 7-year-old boy suffered a bicycle accident with direct trauma to the mouth and extrusive luxation of teeth #11 and #21. The emergency treatment was performed within the first hour. Clinical examinations showed that both teeth exhibited 3 mm extrusion from comparing their incisal edges to their neighboring teeth, had edematous gingiva, showed grade 3 mobility and were painful to percussion. Radiographic exams showed incomplete root formation, widened periodontal spaces along their entire lengths and absence of bone or root fractures. The treatment consisted of immediate repositioning and semi-rigid splinting. After 15 days, tooth #11 exhibited no clinical signor symptom and tooth #21 was diagnosed with pulp necrosis, with an acute dentoalveolar abscess and intraoral edema. Immediate endodontic treatment was initiated (intracanal dressing with calcium hydroxide paste). At 30 days, another pulp sensibility test was performed on tooth #11, which had a negative response. In the same visit, the intracanal dressing of tooth #21 was replaced. The Ca(OH)2 medication was replaced every 6 months until the formation of an apical barrier. The final dressing consisted of gutta-percha and Grossman’s sealer and was placed two and a half years after the first dressing appointment. The extrusive luxation resulted in two different sequelae: complete root obliteration in tooth #11 and anomalous root development after the formation of an apical barrier in tooth #21. The patient received orthodontic treatment after 6 years from the initial treatment with no negative outcome. After 18 years follow-up, both teeth were stabilized with no symptom or sign. It’s important to follow the evolution of every trauma case continuously because the sequelae can be unpredictable
Investigação espectroscópica dos carbonilos heterobimetálicos cis-[Fe(CO)4(HgX)2], X = Cl, Br,I
The series of compounds cis-[Fe(CO)4(HgX)2], X=Cl,Br,I shows an octahedral geometry around the iron atom with the two HgX groups cis to each other. In this paper the assignment for the carbonyl stretching modes and the calculation of their force constants were performed on the basis of the Cotton-Krainhanzel model. Taking into account all the data from the IR, 199Hg NMR and UV-vis spectra it is possible to verify the influence of X on the electronic densities at the metallic centers
