Respiratory disease is the principal cause of loss of young cattle worldwide. The syndrome arises from a number of factors, including those involving the animal, e.g., age, general condition and immune status; its environment, e.g. changes in food, temperature and humidity that lead to stress; and the presence of infectious agents, e.g., bacteria, viruses and mycoplasmas. The syndrome, in a method proposed by the author, can be classified into four grades: Grade 1, subclinical disease; Grade 2, compensated clinical disease; Grade 3, noncompensated clinical disease; and Grade 4, irreversible clinical disease. The increase in frequency and economic impact of bovine respiratory disease complex can be correlated with the escalating industrialisation of cattle produc-tion. In intensive operations, commingling of animals from multiple sources, exposure to many orga-nisms, stress and management practices are all factors that can lead to disease. The predisposition of cattle, espe-cially beef calves, to respiratory problems is related to their lack of functional pulmonary hardiness. Selection of breeds that demons-trate adequate pulmonary function and sufficient ventilatory reserve may help in the control of the bovine respiratory disease complex, but this approach is difficult to implement and slow to produce results. Prophylactic measures, including vaccination programmes and modifying management practices to reduce stress, also have a place in preventing the bovine respiratory disease complex. Unfortunately, these measures are not always easy to put into operation and cannot completely eradicate the problem. Therapeutic strategies to minimise the economic impact of the syndrome include use of appropriate antibacterial therapy, modulation of the pulmonary inflammatory reaction and correction of mechanical disorders [less ▲]

The paper introduces an innovative complexity metric for practical ship design taking into account the shape complexity of steel parts, the assembly complexity of steel components and the material complexity of the structure. The goal is to provide the designer with such information throughout the design process so that an efficient design is obtained at the first design run. Real-time assessment of complexity and quality measure-ments is rather imperative to ensure efficient and effec-tive optimality search, and to allow real-time adjustment of requirements during the design. Application and validation on a real passenger ship show that the new method is effective in giving a complementary aid to decision process for ship designers. [less ▲]

The following problem is proved to be NP-complete: given n tasks, such that each task has processing time \tau=2, and has no more than k=3 possible starting times, does there exist a feasible schedule for these tasks on a single processor? This result establishes a sharp borderline between NP-complete and polynomially solvable versions of this problem with respect to the parameters \tau and k. [less ▲]

We study the dynamics of a two-degree-of-freedom (DOF) nonlinear system consisting of a grounded linear oscillator coupled to a light mass by means of an essentially nonlinear (nonlinearizable) stiffness. We consider first the undamped system and perform a numerical study based on non-smooth transformations to determine its periodic solutions in a frequency-energy plot. It is found that there is a sequence of periodic solutions bifurcating or emanating from the main backbone curve of the plot. We then study analytically the periodic orbits of the undamped system using a complexification/averaging technique in order to determine the frequency contents of the various branches of solutions, and to understand the types of oscillation performed by the system at the different regimes of the motion. The transient responses of the weakly damped system are then examined, and numerical wavelet transforms are used to study the time evolutions of their harmonic components. We show that the structure of periodic orbits of the undamped system greatly influences the damped dynamics, as it causes complicated transitions between modes in the damped transient motion. In addition, there is the possibility of strong passive energy transfer (energy pumping) from the linear oscillator to the nonlinear attachment if certain periodic orbits of the undamped dynamics are excited by the initial conditions.

This report is concerned with a patient aged 76 with mild to moderate aortic stenosis and transient A-V block who was treated by stand-by intracardiac pacing. In spite of this, the patient continued to present syncopal attacks. It is demonstrated that these episodes were related to dramatic decreases of systolic blood pressure and cardiac output occurring whenever the right ventricle was paced. These hemodynamic alterations were secondary to the loss of atrial contribution to ventricular filling. They were suppressed by insertion of a sequential auriculoventricular pacemaker. [less ▲]
