Provedor de dados: 70
Autores: Yu,Ligen; Teng,Guanghui; Riskowski,Gerald L.; Xu,Xuzhang; Guo,Wenzhong.
ABSTRACT This paper presents a web-based data acquisition system developed by the LabVIEW software program for environment monitoring for poultry management. The measurement error and uncertainty analysis should be conducted accurately to maximize the reliability of this system. An algorithm was proposed for the uncertainty analysis to estimate the sensor networks, with the calibration and validation processes fulfilling the standards of the Guide to the Expression of Uncertainty in Measurement. For the different environmental sensors, the values of the uncertainties were calculated by the methods of type A and B evaluation through a case study. Environmental parameters including air temperature, relative humidity, and CO2 concentration of a compartment...

Elements sur le comportement experimental et numerique de la structure d'un voilier de 7m70 en cours de navigation
Provedor de dados: 5
Autores: Baley, C; Cailler, M.
The experimental sailing boat "Mesure Z," has been designed and built on behalf of F.I.N., (the French marine industry association). This research project has been managed in close collaboration with Bureau Veritas, Ifremer and the CEA. The GRP hull is similar to that of a production sailing boat, but it has been designed as a transducer-hull, i.e. a hull sufficiently sensitive to allow measurements (hull strains, acceleration, spar loads, etc), due to its structure and mechanical characteristics. This paper presents different aspects of the experimental boat, the materials and structure of the transducer-hull, and the behaviour of the central and bow regions of the hull during sailing.

An automated photo-oxidation method for the determination of dissolved organic phosphorus in marine and fresh water
Provedor de dados: 5
Autores: Aminot, Alain; Kerouel, Roger.
A segmented flow automated method with on-line photo-oxidation for the determination of dissolved organic phosphorus + soluble reactive phosphorus (DOP + SRP) in seawater and fresh water is described here. A low-power lamp was used for a compact, easy-to-handle and low-ozone-producing manifold. The influence of seawater matrix components was studied in detail using natural seawater and salt solutions spiked with DOP model compounds. Bromide was found to be the most inhibitory species in seawater. The work shows that most salt solutions referred to as artificial seawater are not satisfactory model matrices to test the actual seawater matrix effect. Since DOP recovered in undiluted seawater samples was about half that obtained in fresh water samples, the...

Suspended Sediment Dynamics in the Macrotidal Seine Estuary (France) - Part 1: Numerical Modeling of Turbidity Maximum Dynamics
Provedor de dados: 5
Autores: Grasso, Florent; Verney, Romaric; Le Hir, Pierre; Thouvenin, Benedicte; Schulz, Elisabeth; Kervella, Youenn; Fard, I. Khojasteh Pour; Lemoine, J. -p.; Dumas, Franck; Garnier, Valerie.
Tidal pumping, baroclinic circulation and vertical mixing are known to be the main mechanisms responsible for the estuarine turbidity maximum (ETM) formation. However, the influence of hydro-meteorological conditions on ETM dynamics is still not properly grasped and requires further investigation to be quantified. Based on a realistic 3-dimensional numerical model of the macrotidal Seine Estuary (France) that accounts for mud and sand transport processes, the objective of this study is to quantify the influence of the main forcing (river flow, tides, waves) on the ETM location and mass changes. As expected, the ETM location is strongly modulated by semidiurnal tidal cycles and fortnightly timescales with a high sensitivity to river flow variations. The ETM...

Stature and its Estimation Utilizing Arm Span Measurements in Kosovan Adults: National Survey
Provedor de dados: 77
Autores: Arifi,Fitim; Bjelica,Dusko; Sermaxhaj,Sami; Gardasevic,Jovan; Kezunovic,Miroslav; Popovic,Stevo.
The purpose of this research is to examine stature in both Kosovan sexes as well as its association with arm span, as an alternative to estimating stature. A total of 1623 individuals (830 boys and 793 girls) participated in this research. The anthropometric measurements were taken according to the protocol of ISAK. The relationships between stature and arm span were determined using simple correlation coefficients at a ninety-five percent confidence interval. Then a linear regression analysis was carried out to examine extent to which arm span can reliably predict stature. Results displayed that Kosovan boys are 179.52±5.96 cm tall and have an arm span of 181.29±7.02 cm, while Kosovan girls are 165.72±4.93 cm tall and have an arm span of 165.60±5.87 cm....

It is feasible to think that the body composition assessment may be influenced by maturational and zinc status, especially in young athletes, which perform regularly high volume of physical training. In accordance, it seems important to clarify the impact of these factors in body composition assessment in athletes, since errors may lead to mistakes in training prescription and diet elaboration, and therefore affect the athletic performance. The objective was to compare (1) different methods of body composition evaluation in young soccer players stratified by zinc plasma levels; and (2) the two reference methods using skinfolds thickness in children (Slaughter's and Lohman's equations), considering the maturation level. In this cross-sectional study, fifty...

Human cerebellum is important for motor coordination; muscle tones and maintaing the equilibrium of the body. In our region, limited data is available on the normal morphology of human cerebellum, whilst fresh biopsy is quite difficult to obtain. Here adult male cerebellum from cadaver anatomy preparations embalmed with 37 % formalin fixative solution for over a year are studied (n=3). After removal, right cerebellum hemisphere was sliced into cubicle then temporary soaked into 50-60 % of alcohol before being paraffinated. Two parasagittal adjacent slices from each sample were deparaffinated (5 µm) and then stained with hematoxyllin-eosin (HE). Slides were observed under light microscope (Olympus, Japan). Pictures were analysed from 6 field numbers of...

Autores: Underwood, A.J.
The IOC-IMO-UNEP/GIPME Groups of Experts on Effects of Pollution (GEEP) has been working for a number of years on promoting new ways of understanding how pollutants affect marine biological systems. A major initial focus of GEEP was on calibration workshops where different methods were tested against one another. The Oslo (1986), Bermuda (1988) and Bremerhaven (1992) workshop publications are widely regarded as benchmarks demonstrating that biological effects  methods are reliable tools for measurement of the effects of pollutants discharged to the marine  environment. IOC through GEEP, in cooperation with UNEP, has published a series of manuals based on the successful techniques and these are listed at the back of this volume.  Monitoring programmes for...

The ocean meteorological program of the Weather Bureau has two separate and distinct parts. First, there is the daily service by radio. Owing to the need for brevity, the radio reports contain a limited amount of essential information. The daily weather reports from ships and islands reveal the conditions over the ocean; when assembled on a map, including continental reports, they give a picture of weather conditions existing momentarily over a large region. A collection of observations is immediately returned to the mariner by radio broadcast so that he may draw his own weather map on shipboard. By this process, the weather at the earth's surface is mapped and much can be inferred as to conditions above the surface. Formation and movement of storms are...

Instructions to the Marine Meteorological Observers of the U. S. Weather Bureau, 3rd edition.
Provedor de dados: 20
Autores: Heiskell, Henry L.
Introduction.- The Meteorological Report at present issued to vessels by the U. S. Weather Bureau, for forwarding observations , is a slight modification of that devised by the U. S. Signal Service for the purpose of its series of International Simultaneous Meteorological Observations, covering the period 1878-1887, which form in its turn superseded the once well-known Meteorological Journal. The last-mentioned form of record, which went into effect in 1876, and wh ch was in many respects identical with that recommended by the Maritime Conference held at Brussels in 1853, contemplated that the various meteorological observations should be entered at the end of every two hours throughout the twenty-f our, or a total of twelve sets of observations a day. The...

The Newman method, modified for the estimation of the total thallus length of filamentous algae
Provedor de dados: 27
Autores: Gillis, J.
Newman's (1966) method of total root length estimation is modified and adapted to measure total length of filamentous algae in culture (i.c. &lt;i&gt;Polysiphonia&lt;/i&gt;). This method makes possible a measurement and an estimation of the growth of the algae in culture without disturbing them. The petri dishes are placed on a 1x1 mm grid and the filament/grid intersections are counted. Total filament length (T) is given by T = Pi N (LxW)/4(LxW), with N = the number of intersections, L = the length and W = width of area in which the thallus is situated. Total filament length of &lt;i&gt;Polysiphonia&lt;/i&gt; in culture estimated by the Newman method is compared with camera lucida measurements. The correlation between the results obtained by the 2...

The Measurement, Monitoring and Evaluation Strategy
Provedor de dados: 31
Autores: Alford,   Andrew R.; Clark,   Richard A.; Griffith,   Garry R.
A critical component of the Continuous Improvement and Innovation (CI&amp;I) process described in Paper 4 above is Performance Assessment - analysing and interpreting the results achieved, and not achieved, in relation to the focus and target outcomes. This is made easier if specific Key Performance Indicators (KPIs) are established during Action Design and monitored during Action Implementation. The target outcome for the Measurement, Monitoring and Evaluation (MME) Strategy is to design and implement effective and efficient MME mechanisms that will demonstrate improvements and innovations in individual beef businesses and supply chains and in the broader Australian beef industry.

How can we evaluate conservation auctions? Three Possible methods
Provedor de dados: 31
Autores: Schilizzi,   Steven.
By design, tenders are used when costs are unknown. But if costs are unknown, how can we evaluate the tenders, when their evaluation involves measuring their cost-effectiveness? We identify three approaches: theoretical, empirical and experimental. We first use experimental data to compare the efficiency of each approach, then apply the most efficient one to field data from the Scottish fishing vessel decommissioning program. We estimate the potential errors one would make in using a less efficient approach. In this case, we demonstrate a novel use of controlled lab experiments for interpreting field data and evaluating policy effectiveness.

Measuring Biodiversity – an axiomatic evaluation of measures based on genetic data
Provedor de dados: 31
Autores: Gerber,   Nicolas.
Biodiversity measurement is necessary to evaluate conservation alternatives and understand how to maximize biodiversity returns on conservation budgets. In the economics literature, most studies focus on species level diversity. Existing measures based on species' pairwise genetic differences do not perform optimally. This paper develops two new biodiversity measures within the same genetic framework. An axiomatic diagnosis for this class of measures is proposed and four biodiversity measures are then compared. Though the axiomatic comparison points towards a single "best" measure, it also indicates that the choice of measure should be dependent on the conservation problem at hand.

Are poor, remote areas left behind in agricultural development: the case of Tanzania
Provedor de dados: 31
Autores: Minot,   Nicholas.
In Tanzania, as in many other developing countries, the conventional wisdom is that economic reforms may have stimulated economic growth, but that the benefits of this growth have been uneven, favoring urban households and farmers with good market access. This idea, although quite plausible, has rarely been tested empirically. In this paper, we develop a new approach to measuring trends in poverty and apply it to Tanzania in order to explore the distributional aspects of economic growth and the relationship between rural poverty and market access. We find that, between 1991 and 2003, a period of extensive economic reforms, the overall rate of poverty fell about 9 percentage points. The degree of poverty reduction was similar between rural and urban areas,...

Applying and Extending the Sustainable Value Method related to Agriculture – an Overview
Provedor de dados: 31
Autores: Illge,   L.; Hahn,   Tobias; Figge,   F.
Sustainable Value is a method to measure the contribution of an economic entity, such as a farm or the entire agricultural sector, towards the sustainability (sustainable development) of a region, a country or on a global scale. A positive sustainable value is created once resources are used more efficiently than by a benchmark. It shows the excess return that is created or lost by the use of economic, environmental and social resources by an economic entity relative to a benchmark. The purpose of this paper is to give an overview on the characteristics and requirements of the SV and to provide information on (a) possible applications and (b) extensions of the SV method related to the agricultural sector. A particular emphasis is put on the choice of...

Measuring Public Agricultural Research Capital and Its Contribution to State Agricultural Productivity
Provedor de dados: 31
Autores: Huffman,   Wallace E.
A methodology for measuring public agricultural research capital is developed and described for the first time, new public agricultural research capital measures for each of the 48 contiguous US states, 1970-1999, are presented, and a new econometric analysis of the contribution of public agricultural research capital to state agricultural productivity is reported. Public agricultural research capital across the states is shown to have five different growth patterns, only one of which is at a constant rate. New TFP results show that public agricultural research capital contributes significantly to agricultural productivity and is larger than previous estimates. Intrastate and spillin public agricultural research capital are shown to be complementary, but...

Measuring food security: Definitional sensitivity and implications
Provedor de dados: 31
Autores: Bashir,   Muhammad Khalid; Schilizzi,   Steven.
Six methods for measuring food security are identified from the literature. The dietary intake method (DIM) and the food insecurity experienced-based measurement scales (FIEMS), the two most commonly used, were empirically tested using 1152 rural households in the Punjab province of Pakistan. Results show significant differences in the measurement of food insecure households: 22.9% with DIM vs. 4.7% with FIEMS. A slight change in the food security definition resulted in significant differences. With slight definitional changes, 6.5% of the sample households appeared food insecure using DIM and only 1.1% using FIEMS. Given its high definitional sensitivity, food security must be carefully defined according to country specific conditions and should reflect...

If services aren't delivered, people won't pay: the role of measurement problems and monitoring in Payments for Environmental Services
Provedor de dados: 31
Autores: Meijerink,   Gerdien W.
The idea of Payments for environmental services (PES) has an appealing simplicity, which may explain the success of the concept. However, successful projects are far limited though and two constraints have been identified in literature. The first is limited demand: too few service users are so confident about the mechanism that they are willing to pay. The second obstacle is poor knowledge on the institutional requirements entailing incentive and livelihood mechanisms which so far have received comparatively less attention. This paper focuses on both constraints by arguing that monitoring effectiveness and conditionality of PES schemes are crucial and that institutional arrangements for monitoring should be in place. By analysing in a systematic way what...

Morphometry of eggs and immatures of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) obtained in the laboratory and on the field
Provedor de dados: 104
Autores: Zequi,João A. C.; Lopes,José.
The objectives of this morphometric study of Culex (Culex) saltanensis Dyar, 1928 larvae were to observe the continuous growth of siphon and cephalic capsule length and width in each instar, and to propose a linear equation to differentiate instars according to the size of both structures. Larvae obtained in laboratory at 27 ± 1ºC, photoperiod 14L:12D were studied. Larvae of the forth instar were collected on the field and compared with same instar larvae reared in the laboratory. Egg size and pigmentation pattern, first instar continuous growth, and differentiation of larval stages measurements were studied. Egg pigmentation patterns and the shapes of raft eggs differentiated specimens of C. saltanensis from Culex (Culex) quinquefasciatus Say, 1823 found...

Measurement of volatilized mercury by a mini-system: a simple, reliable and reproducible technique
Provedor de dados: 52
Autores: Cursino,Luciana; Mattos,Silvânia V. M.; Silva,Nilton O.; Chartone-Souza,Edmar; Nascimento,Andréa M. A.
A simple and easy new technique for volatilized mercury determination in biological systems was developed. This technique is fast and sensitive and can overcome the problems that arise due to the extremely low readings during the measurements and reproducibility in biological material (bacteria). It measures directly the volatilized metallic mercury of bacteria by means of a chemical adsorbent in a coupled mini-system, as a modified technique for mercury in air analysis. It is potentially of interest to the bioremediation and bacterial mercury resistance communities

Influence of the temperature, pressure and viscosity on the oil measurement with turbine type measurers
Provedor de dados: 52
Autores: Damasceno,Magalí Araújo; Penha,Janaina Karla de Medeiros; Silva Junior,Nivaldo Ferreira da; Felipe,Raimundo Nonato B.; Felipe,Renata Carla Tavares dos Santos; Medeiros,Gilson Gomes de.
The flow measurement of liquids and gases is a necessity in many industrial applications. There is a great amount of measurers for such purpose, as, for example, the coriolis, positive displacement and type turbine measurers. A measurer sufficiently used for the oil flow measurement is the turbine type, because it uses the proper extracted energy of the measured flow for its functioning, moreover is also used as standard for the calibration of other measurers. For this reason, it is important to study the parameters that influence the measurement process for turbine measurers. In Brazil, to measure the volume of oil, regardless the type of measurer, it is necessary to observe "Portaria Conjunta Nº. 1", of June 19, 2000, that approved the Technical...

Patch-clamp detection of macromolecular translocation along nuclear pores
Provedor de dados: 56
Autores: Bustamante,J.O.; Varanda,W.A.
The present paper reviews the application of patch-clamp principles to the detection and measurement of macromolecular translocation along the nuclear pores. We demonstrate that the tight-seal 'gigaseal' between the pipette tip and the nuclear membrane is possible in the presence of fully operational nuclear pores. We show that the ability to form a gigaseal in nucleus-attached configurations does not mean that only the activity of channels from the outer membrane of the nuclear envelope can be detected. Instead, we show that, in the presence of fully operational nuclear pores, it is likely that the large-conductance ion channel activity recorded derives from the nuclear pores. We conclude the technical section with the suggestion that the best way to...
