Nucleus Animalium , 2012,
Abstract: The aim of this experiment was to evaluate performance of Japanese quail male subjected to different levels of energy and protein in the diet, and the carcass yield and chemical composition of meat. 216 quails were distributed on nine treatments, four replicates and six birds per cage. At 38 days the quails were distributed in a completely randomized design, factorial scheme 3x3, in three levels of metabolizable energy (2,600; 2;800 and 3,000 kcal ME/kg), and three levels of crude protein (16, 18 and 20%), composing the experimental diets supplied until 56 days old. The results showed that the original dry matter was significantly higher in meat from quails subjected to treatment with 2,600 kcalME/kg followed by meat from quails fed with 3,000 kcalME/kg. The quantity of total fat was also higher in meat from quails fed diets with 2,600 and 3,000 kcalME/kg. There was no influence of different levels of energy and protein of the diets on parameters of performance and quality of meat. We conclude that the lower levels of energy and protein in the diet did not affect the performance, carcass yield and meat chemical composition of Japanese quails male.Tendo o objetivo de avaliar o desempenho, o rendimento de carca a e a composi o química da carne de codornas japonesas macho submetidas a diferentes níveis de energia e proteína na dieta, 216 codornas foram distribuídas em nove tratamentos, quatro repeti es e seis aves por parcela. Aos 38 dias de idade as aves foram distribuídas em delineamento inteiramente casualizado, em esquema fatorial 3 x 3, sendo três níveis de energia (2.600, 2.800 e 3.000 kcal EM/kg) e três níveis de proteína (16, 18 e 20%), constituindo as ra es experimentais fornecidas até 56 dias de idade. Os resultados mostraram que a matéria seca original foi significativamente mais elevada na carne das aves submetidas ao tratamento contendo 2.600 kcal EM/kg de ra o seguida pela carne das aves alimentadas com 3.000 kcal EM/kg. A quantidade de lipídios totais também foi maior na carne das aves alimentadas com ra es contendo 2.600 e 3.000 kcal EM/kg de ra o. N o houve influência dos níveis de energia e proteína das dietas nos parametros de desempenho e qualidade de carne. Conclui-se que os menores níveis de energia e de proteína na dieta n o afetaram o desempenho, o rendimento de carca a e a composi o química da carne de codornas machos para postura.

Abstract: Coccidiosis is a disease caused by intracellular protozoan parasites, specifically belonging to the genus Eimeria. These parasites target the gastrointestinal tract in different types of hosts, causing sores in the intestinal lining. The presence of these lesions reduces the animal’s ability to digest and absorb nutrients, significantly impacting their overall performance. The current study aimed to explore the potential correlation between seasonal variations and the incidence of Eimeria spp-induced lesions in broiler chickens’ gastrointestinal tracts in Brazil from 2012 to 2018. A total of 8,607 broiler chickens, aged 14 to 42 days, were sampled from 103 poultry integrated companies in Brazil to conduct intestinal health examinations. The sampling process involved selecting 3 to 6 chickens from each poultry house for examination. The assessment included various abnormalities such as shedding of intestinal cells and excessive fluid and mucus presence, thickening and tension of the intestines, food movement, roughened mucosal surface resembling a Turkish towel in the small intestine, tissue death, duodenal inflammation, intestinal inflammation, gizzard erosion, presence of worms and bedding material, and ingestion of mealworms. During the seasons, winter exhibited the highest average occurrence of Eimeria maxima microorganisms at 52.83%, with E. acervulina following closely at 26.42% in second place. In spring, E. maxima had an occurrence of 11.31%, while in fall, E. tenella had the lowest occurrence at 6.74%.
Analysis of Superimposed Elementary Thermodynamic Cycles: from the Brayton-Joule to Advanced Mixed (Auto-Combined) Cycles
Andrea Lazzaretto,Giovanni Manente
International Journal of Thermodynamics , 2009, DOI: 10.5541/ijot.247
Abstract: The need for efficiency improvement in energy conversion systems leads to a stricter functional integration among system components. This results in structures of increasing complexity, the high performance of which are often difficult to be understood easily. To make the comprehension of these structures easier, a new approach is followed in this paper, consisting in their representation as partial or total superimposition of elementary thermodynamic cycles. Although system performance cannot, in general, be evaluated as the sum of the performance of the separate thermodynamic cycles, this kind of representation and analysis can be of great help in understanding directions of development followed in the literature for the construction of advanced energy systems, and could suggest new potential directions of work. The evolution from the simple Brayton-Joule cycle to the so called “mixed” cycles, in which heat at the turbine discharge is exploited using internal heat sinks only without using a separate bottoming section, is used to demonstrate the potentiality of the approach. Mixed cycles are named here "auto-combined cycles” to highlight the combination of different (gas and steam) cycles within the same system components. This paper is an updated version of a paper published in the ECOS'08 proceedings.

The collection of international tourism expenditure statistics on open area: methodology and applications - the case of the Veneto region
Manente, Mara,Minghetti, Valeria
- , 1998,
Abstract: Sa？etak It is now generally acknowledged the need of collecting information on the expenditure behaviour of inbound tourists, which is crucial for estimating the macro-economic impact of tourism in an area (open or closed) in terms of GDP, employment and balance of payments. The survey on inbound tourist expenditure in the Veneto region here described represents the first step towards the development of a Regional Tourism Information System, useful not only for researchers but also for all public and private operators involved in tourism management, marketing and planning. The paper describes objectives, methodology and organisation of this survey, by providing the analytical framework for the systematic collection of data on characteristics and consumption behaviour of inbound tourists
Making Sense of Environmental Complexity in a Reform Context: The Case of Megaproject Alpha  [PDF]
Marcel Veenswijk
American Journal of Industrial and Business Management (AJIBM) , 2012, DOI: 10.4236/ajibm.2012.24015
Abstract: In this paper, new concepts on environmental complexity and sense making are developed and explored and analysed. The article based on a case study regarding a public-private collaboration in a Dutch infrastructural mega project. It is argued that the ability to influence the direction of the change process of the mega project “Alpha” depends on the way actors are able to influence the so aleed “cultural interfaces” into the power arena by means of a specific group of organizational stakeholders. After a short theoretical introduction, we describe the case in terms of two dominant cultural stages and their specific interface dynamics. The paper concludes with a general reflection on the central concepts.

Abstract: infamy, violence and madness are problematics that they given at one time in one space, with their local particularities and also with likeness and continuances between the past and the present. foucault's thought allows us to reveal the hidden things and allows to make visible the invisible things. we must to see the reals problems of the daily life in salta, at the end of the xix century. we have to move away from the anecdote to think about the social differences and to be able to analyze how the power was with transgressor, the criminal and the lunatic.
Narrating National Geo Information Infrastructures: Balancing Infrastructure and Innovation  [PDF]
Henk Koerten, Marcel Veenswijk
Journal of Service Science and Management (JSSM) , 2009, DOI: 10.4236/jssm.2009.24040
Abstract: This paper examines narratives relating to the development of National Geo Information Infrastructures (NGII) in ethnographic research on a Dutch NGII project which was monitored throughout its course. We used an approach which focuses on narratives concerning the environment, groups and practice to elicit sense-making processes. We assert that narratives are relatively fixed and that they only change under specific circumstances. Moreover, the fixing of or change in narratives takes place in practice, so our research approach aimed at analysing narratives of practice, which we label ‘storyboards’. For this purpose, project meetings and conferences were observed, key persons both within and outside the project environment were interviewed, and an analysis of relevant documents and video footage was undertaken. Storyboards are created by actors as a result of day-to-day challenges related to project goals, technology and infrastructure. In our research we found that these storyboards occur as vicious circles from which actors cannot escape. In the specific case analysed, our interpretation of the narrative storyboards suggested that these vicious circles are caused by the inability of project participants to distinguish between infrastructure and innovation requirements in their daily work.
A Value-Based and Multi-Level Model of Macro Economies  [PDF]
Marcel van Marrewijk
Technology and Investment (TI) , 2010, DOI: 10.4236/ti.2010.11005
Abstract: There is sufficient evidence that performance levels of various economic systems differ. All systems seem to have particular benefits, but all of them are adequately aligned with the dynamics and complexity of con-temporary societies. In this paper, the author introduces a sequence of ideal type economic systems, based on Spiral Dynamics, a theory explaining levels of existence within people, groups of people, organizations and societies. Per type the author elaborates on the underlying value systems and relating institutional structures, such as leadership style, governance and measurement format.
