  • This study describes the growth of broiler chickens to the two forms of Gompertz function for application in broiler production models. The first form is based on the estimated mature weight ($W_A$), while the second is based on the estimated hatch weight ($W_O$). Both equations gave identical estimation because they are mathematically identical. To fit the growth curve of commercial broilers that marketed at 35-42 days, it is unnecessary to keep broilers to near maturity (> day 140) to obtain growth data for deriving the Gompertz function. This date does not improve the curve fitting of the early growing period. Additionally, a high mortality and health problem occurred to this type of chicken after day 105.

  • Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation predict requirement for ECMO. In these patients, ECMO should be considered earlier as the clinical course of AFM can be unpredictable and can lead to rapid haemodynamic collapse. Key uncertainties that clinicians face when managing children with AFM such as timing of initiation of ECMO and left ventricular decompression need further investigation.

  • A dynamic Monte Carlo percolation grid simulation is used to predict the cure behaviour of thermoset materials. Molecules are distributed in a fixed grid and a probability of reaction is assigned to each pair of neighbouring units considering both reaction rates and diffusion. The concentration and network characteristics are predicted throughout the whole curing process and compared to experimental data for an epoxy-amine matrix.

  • An investigation was conducted to determine whether the rumen modifiers lasalocid and avoparcin, when included in molasses/urea based supplements, enhanced liveweight performance, in early weaned calves. As part of the study the broad-spectrum parasiticle Avermectin B1 was given to the calves to assess any undesirable side effects on animals of less than four months of age. There were no significant (p>0.05) liveweight responses to supplementation when the rumen modifiers lasalocid and avoparcin were included in supplement rations. Lasalocid reduced supplement intake, however, it had no adverse effect on liveweight gain. Avoparcin substantially improved growth when cottonseed meal was included in the ration. Weaners treated with Avermectin B1 tended to show a greater liveweight gain than untreated weaners during the experiment (p<0.10) and no adverse side effects were noted.

  • Vibration characteristics of columns are influenced by their axial loads. Numerous methods have been developed to quantify axial load and deformation in individual columns based on their natural frequencies. However, these methods cannot be applied to columns in a structural framing system as the natural frequency is a global parameter of the entire framing system. This paper presents an innovative method to quantify axial deformations of columns in a structural framing system using its vibration characteristics, incorporating the influence of load tributary areas, boundary conditions and load migration among the columns.

  • Medical records must be well protected because they are needed to care for the health of patients. For that reason, user authentication and medical data encryption are essential for the security of both wired and wireless Healthcare Information Systems (HIS). The main focus of this paper is on the analysis of the numerous possible attacks and the countermeasures to overcome these attacks in Mobile Healthcare Environment (MHE) with an appropriate security protocols. To draw a conclusion, this will propose why a healthcare architecture should establish a multi-layered defense against the risks.

  • This review summarises the biology, discovery and applications of single nucleotide polymorphisms in complex polyploid crop genomes, with a focus on the important oilseed crop $Brassica$ $napus$. $Brassica$ $napus$ is an allotetraploid species, and along with soybean and oil palm is one of the top three most important oilseed crops globally. Current efforts are well underway to $de$ $novo$ assemble the $B.$ $napus$ genome, following the release of the related $B.$ $rapa$ 'A' genome last year. The next generation of genome sequencing, SNP discovery and analysis pipelines, and the associated challenges for this work in $B.$ $napus$, will be addressed. The biological applications of SNP technology for both evolutionary and molecular geneticists as well as plant breeders and industry are far-reaching, and will be invaluable to our understanding and advancement of the $Brassica$ crop species.
