In some production settings, beef bulls are mixed at the beginning of the finishing period to obtain homogeneous groups to facilitate finishing and to produce more homogeneous carcasses. Given the stress induced by mixing, we questioned whether this practice was profitable. Sixty-four young bulls were finished in groups of four over 8 mo. They were either mixed or unmixed and had either homogen...

the present study was conducted to evaluate the effect of parenteral supplementation of cobalt, copper and iron in late pregnancy on ewe hematology parameters and lamb vigour. twenty ewes were allocated to one of two groups (n=10). in the test group, on day 120 ofpregnancy, cobalt, copper and iron were injected at a dose of 0.1 ml/kg bw (fercobsang, france, cobalt gluconate 5 mg/100 ml, copper ...

OBJECTIVES To assess safety, tolerance and efficacy of liposomal amphotericin B (LAMB) in a large unselected series of paediatric cancer/haematopoietic stem cell transplantation (HSCT) patients requiring LAMB therapy. PATIENTS AND METHODS The study included 84 children and adolescents (median age: 11 years) who received 141 consecutive courses of LAMB for prophylaxis (32), empirical therapy (...

Ewe performance was compared for five pure breeds of sheep (Finnsheep, F; Rambouillet, R; Dorset, D; Targhee, T; Suffolk, S) and the crosses in development of two maternal composite lines (C1 = 1/2F1/4R1/4D and C2 = 1/2F1/4T1/4S). The data involved 10,959 breeding season records of 4,219 ewes by 412 sires. Ewe production and the components (fertility, litter size, neonatal and preweaning lamb s...

It is well known that harmonic bounded Gaussian beams undergo a transformation into two bounded beams upon reflection on a solid immersed in a liquid. The effect is known as the Schoch effect and can be found at the Rayleigh angle for thick plates and at the different Lamb angles for thin plates. Here, a study is made on the effect of pulsed Gaussian beams reflected on solids. It is found exper...

OBJECTIVE To evaluate the results of a finishing protocol implemented in patients treated in the Orthodontics graduate program at Universidad de Antioquia. Evaluation was carried out by means of the criteria set by the Objective Grading System (OGS) of the American Board of Orthodontics (ABO). METHODS Cast models and panoramic radiographs of 34 patients were evaluated. The intervention group ...

Studies were conducted to evaluate the effects of delayed implanting or the use of a low-dose implant followed by a higher-dose implant in feedlot cattle. In the first study, 150 steers were allotted to 15 pens (three pens/treatment) and assigned to a nonimplant treatment (control), a single zeranol (36 mg) implant (R), or a double zeranol implant (DR) administered at the start of a 140-d finis...

Objectives This study aimed to assess the effect of wet and dry finishing and polishing on microhardness and roughness of microhybrid and nanohybrid composites. Materials and Methods Thirty samples were fabricated of each of the Polofil Supra and Aelite Aesthetic All-Purpose Body microhybrid and Grandio and Aelite Aesthetic Enamel nanohybrid composite resins. Each group (n=30) was divided int...

The original Lamb system was introduced by Horace Lamb in 1900, [13], as a simple model for the phenomenon of radiation damping experienced by a vibrating body in an energy conducting medium. Examples include vibrations of an elastic sphere in a gaseous medium, electrical oscillations of a spherical conductor, a dielectric sphere with large inductance, relativistic radiation of energy from a co...
