the present experiment was undertaken to study the effect of different dosages of β-glucan on the growth, survival and physiological responses in juvenile striped catfish ( pangasianodon hypophthalmus ). over nine weeks of feeding fish with a diet containing 0, 0.5, 1 and 2% β-glucan (as control, g1, g2 and g3 group, respectively), some blood parameters such as serum lysozyme activity, total pr...

In this article we defend the idea that social aspects have strong influence in the software requirements elicitation (Goguen 1993), which drive us to find help in the social sciences. The Activity Theory is a theory developed in the Psychology that focuses the human practices of development process, both the individual and social levels. This theory states that any human action must be underst...

Requirements management measures can help us to control changing software requirements and estimate the costs of changing requirements. The goal of this paper is twofold. First we describe a set of requirements measures and validate these measures applying two definitions from the literature. After that we describe a case study using these measures to estimate the cost of changes to requirement...

In networked environments, the importance of eliciting security requirements as part of the process of requirements elicitation is increasing. Yet, it is difficult to articulate what security requirements are and how they can be elicited and implemented in the system. Few security requirements elicitation methods deal with the security needs of the end-users in specific contexts towards other e...

This article presents the well established theoretical base and clinical practice of exposure therapy for trauma. Necessary requirements for positive treatment results and contraindicated procedures are reviewed. EMDR is contrasted with these requirements and procedures. By the definitions and clinical practice of exposure therapy, the classification of EMDR poses some problems. As seen from th...

Plant protein foods contribute approximately 65% of the per capita supply of protein on a worldwide basis and approximately 32% in the North American region. These sources of protein are discussed in relation to their amino acid content, human amino acid requirements, and dietary protein quality. Mixtures of plant proteins can serve as a complete and well-balanced source of amino acids for meet...

The theory that birds evolved from a group of small terrestrial theropod dinosaurs has created much controversy. One argument proposed against this theory is that the lungs of early theropods were incapable of sustaining endothermic gas exchange requirements and could not have given rise to the lungs of birds. A reexamination of the comparative physiological and morphological literature combine...

Quantifying the energy requirements of animals in nature is critical for understanding physiological, behavioural, and ecosystem ecology; however, for difficult-to-study species such as large sharks, prey intake rates are largely unknown. Here, we use metabolic rates derived from swimming speed estimates to suggest that feeding requirements of the world's largest predatory fish, the white shark...

Pig breeding programs focus on growth and carcase composition traits in the growing pig as well as higher reproductive performance of sows leading to considerable genetic gain in these traits. These changes in genetic potential have consequences for piglet survival and husbandry requirements of sows. For example, comparison of body composition and physiological state of piglets from boars born ...

A practical implementation of a wearable physiological and environmental monitoring system is presented. The technical requirements for wearable electronics and sensors are analyzed. A proposed system includes micro and nano device design, wireless network based on TCP/IP protocol and software application. The result samples from monitoring in ambulatory environment are discussed.
