Applying Spruce Needle Extractives in Broiler Chicken Feeding

Spruce needle extractive substances were produced from a forestry by-product - green biomass of spruce needles. Spruce needle extracts contain a significant amount of natural biologically active substances. During our investigations the evaluation of biologically active substances from spruce needle total extract and of neutral extracts was carried out to assess their effects on innovative composition broiler chicken meat. The feeding trial was conducted with cross Ross 308 broiler chickens by adding the spruce needle total extract and, separately, neutral extract substances to the composition of broiler chickens' diet. Using spruce needle extractive substances increased live weight on average by 4.31-7.58% (P < 0.05) and decreased feed conversion by 6.28-7.33% in comparison with the control group. The use of neutral extract substances in the poultry diet improved the composition of fatty acids, increased the amount of total carotenoids by 0.45-0.57 mg kg −1 and decreased the cholesterol level by 11.16-23.66 mg 100g −1 in meat.
REMEDIATION AND REUSE OF RETTING FLAX WASTEWATERUSING ASP FOLLOWED BY ADSORPTION ON AC

Remediation and reuse of retting flax wastewater using activated sludge process (ASP) followed by adsorption on activated carbon (AC) were investigated. Wastewater produced (350 m3/d) is characterized by brownish to yellow color, bad odor and high organic contents due to lignin, cellulose and hemicelluloses in the flax fibers wastewater. Biodegradation of the organic contaminants was achieved successfully using ASP in presence of adapted culture containing pectin enzymes released by bacteria at a detention time of 6 h. The efficiency of ASP for chemical oxygen demand (COD), biological oxygen demand (BOD) and total suspended solids (TSS) were 95.86%, 94.53% and 97.6%, respectively. For wastewater reuse, post treatment was carried out using adsorption on AC with a dose of 2 g/L and at a contact time of 45 min. kinetics and adsorption isotherm was investigated. It was found that the sorption of residual COD from flax wastewater follows the second order kinetics and data fits both Langmuir and Freundlich isotherm models. The maximum adsorption capacity (qmax) of COD over AC was 333.33 mg/g. Residual COD, BOD and TSS were 38 mg O2/L, 9 mg O2/L and 2 mg/L, respectively which comply with the National Regulatory Standards for reuse.
Case-series analysis of intracranial saccular aneurysms treatment

Nowadays, selection of the best treatment method for intracranial aneurysms is one of the most discussed topics. We report our operative and coiling experience of 128 cases – series with 106 ruptured and 22 unruptured aneurysms. The aim of the research was to identify the factors influencing the optimal radical method for treatment of intracranial aneurysms and to compare the neurosurgical and neuroradiological activity of our hospital with that of other regions of the world. Of 128 aneurysms the clipped group was 94 patients (mean age ± SD: 52.21 ± 13.34 years, 73.4%) while 34 patients underwent aneurysm embolization (mean age ± SD: 61.59 ± 13.34 years, 36.6%). Most of the aneurysms were located at the anterior communicating artery (n = 36, 28.13%), the middle cerebral artery (n = 34, 26.56%) and the internal carotid artery (n = 20, 15.63%). Comorbidity, neurology status at admission, clinical outcomes, operative complications, aneurysm localization, size and condition were analysed. According to our experience, surgical clipping of aneurysms is more efficient and safe for patients with no or mild comorbidity, with less severe neurological symptoms, ruptured aneurysms, and anterior cerebral circulation aneurysms.
Are Constant Interest Rate Forecasts Modest Interventions? Evidence from an Estimated Open Economy DSGE Model of the Euro Area

This paper uses an estimated open economy DSGE model to examine if constant interest forecasts one and two years ahead can be regarded as modest policy interventions during the period 1993Q4-2002Q4. An intervention is here defined to be modest if it does not trigger the agents to revise their expectations about the inflation targeting policy. Using univariate modesty statistics, we show that the modesty of the policy interventions depends on the assumptions about the uncertainty in the future shock realizations. In 1998Q4-2002Q4, the two year constant interest rate projections turn out immodest when assuming uncertainty only about monetary policy shocks during the conditioning period. However, allowing non-policy shocks to influence the forecasts makes the interventions more modest, at least one year ahead. Using a multivariate statistic, however, which takes the joint effects of the policy interventions into consideration, we find that the conditional policy shifts all projections beyond what is plausible in the latter part of the sample (1998Q4-2002Q4), and thereby affects the expectations formation of the agents. Consequently, the constant interest rate assumption has arguably led to conditional forecasts at the two year horizon that cannot be considered economically meaningful during this period.
Roughness-Induced Vibration Caused by a Tangential Oscillating Mass on a Plate

This work examines the dynamic behavior of a system consisting of a mass-block on the rough surface of a simply supported plate, harmonically excited in the tangential direction. The vertical excitation emerges from roughness, tracked by the mass-block. Low-frequency sliding results in high-frequency vertical excitation up to the ultrasonic range. The conditions of the elastic contact between the two bodies are modeled in the form of vertical contact stiffness. A specific friction law with a behavior similar to an elastically coupled coulomb damper represents the tangential direction. The model allows for the study of the interaction between the tangential friction behavior and the vertical roughness-induced vibrations. Parameters of interest are friction velocity, mass-block weight, surface roughness, and contact material. Because of nonlinearities, the theoretical model must be solved within the time domain. The theoretical results are verified through experimental results of a corresponding setup. The subject combines material science, contact mechanics, and structural dynamics. [DOI: 10.1115/1.4005828]
Explorer Weighted Model Counting With Function Symbols

Probabilistic relational languages lift the syntax of relational logic for the specification of large-scale probabilistic graphical models, often admitting concise descriptions for interacting random variables over classes, hierarchies and constraints. The emergence of weighted model counting as an effective and general approach to probabilistic inference has further allowed practitioners to reason about heterogeneous representations, such as Markov logic networks and ProbLog programs, by encoding them as a logical theory. However, much of this work has been limited to an essentially propositional setting: the logical model is understood in terms of ground formulas over a fixed and finite domain; no infinite domains, and certainly no function symbols (other than constants). On the one hand, this is not surprising, because such features are very problematic from a decidability viewpoint, but on the other, they turn out to be very attractive from the point of view of machine learning applications when there is uncertainty about the existence and identity of objects. In this paper, we reconsider the problem of probabilistic reasoning in a logical language with function symbols, and establish some key results that permit effective algorithms.
How do users decide whether to follow a call to action in an online message ?

Being able to predict how internet users react when confronted with a potentially dangerous call for action in an online message (such as an e-mail) is important for several reasons. On the one hand, users have to be protected from fraudulent e-mails such as phishing. On the other hand, over-cautious users would be difficult to communicate with on the internet, so senders of legitimate messages have to know how to convince recipients of the authenticity of their messages. Extensive research already exists from both of these perspectives, but each study only explores certain aspects of the complex system of factors influencing users’ reactions. In this paper the results of our efforts to integrate the various existing findings into one comprehensive model are presented, along with the results of a preliminary qualitative evaluation of some of the model’s predictions using quantitative as well as qualitative measures and eye-tracking.
A minimum incoming weight label method and its application in CPM networks

An efficient approach towards finding a directed, shortest path or a directed longest path from the source to all other nodes in a directed network is described in this paper. Application of this approach with respect to CPM project networks is also considered. The approach is based on a minimum incoming weight labelling method and determines a critical path for a given project activity network. Although many algorithms exist in the operational research literature that may be used to find critical paths, the method discussed in this paper has an interesting application in determining optimal crash limits for various activities in a CPM network. In case of network topology changes due to any reason, such as that an activity has to be completed in crash duration or the actual duration of an activity takes longer than scheduled, a new critical path and new associated floats can be computed without analyzing the complete network all over again. This is achieved by recycling part of the available information. The algorithm presented in this paper is illustrated by means of numerical examples.
No Trade, Informed Trading, and Accuracy of Information

We present a model in which there is uncertainty about realization of a risky asset value for an informed trader. We introduce two states such that in the "narrow" state the informed trader has better information than in the "wide" state. Then, we show that the informed trader in the wide state does not trade in equilibrium if the information that the informed trader with better information has is sufficiently accurate and the probability of the narrow state is sufficiently high. We use the framework presented by Glosten and Milgrom (1985) and extend the assumption that the informed trader knows the terminal value of the risky asset. Finally, we obtain the conditions under which the informed trader would not trade in equilibrium.
Application of statistical analysis in result repeatability evaluation ofacoustic emission measurements generated by partial discharges

The subject matter of this paper deals with the improvement of the acoustic emission (AE) method in diagnostics of insulation systems of power appliances. The paper presents the results of the statistical analysis of the AE pulses generated by the setups modeling basic partial discharge (PD) forms that can occur in oil insulation systems. Especially, the results of parametric and non-parametric tests of quality of fit are presented that were carried out in order to determine the probability distribution of the AE pulses measured, to test the repeatability of the frequency analysis results obtained, and to check the influence of the factors that can disturb this repeatability. The statistical analyses were carried out based on the values of three descriptors, i.e. shape coefficient, peak coefficient and median frequency, which make the identification of basic PD forms occurring in insulation oil possible.
Effectiveness of the enforcement of industrial emission standards in Montevideo, Uruguay

Unfortunately, the empirical literature on the enforcement of industrial emissions standards refer to case studies in the developed world, mostly the U.S. and Canada. There does not exist any example of this type of empirical work for Latin America. In fact, Dasgupta, et al. (2001) and Wang et al. (2002) are the only examples of empirical studies of effects of inspections and fines on pollution levels and the determinants of the monitoring and enforcement activities of regulators, respectively, for a less developed country (China). This constitutes a very important shortcoming because Latin America has a long tradition in water pollution control laws, but both public opinion and papers that have analyzed environmental policy in the region have regarded them as poorly enforced. Furthermore, many resources are being devoted to developing new regulations and instruments, but no effort is being made to assess the effectiveness of the existing ones. This paper contributes to fill this gap by empirically testing the effect of inspections and enforcement actions of the municipal and national governments on industrial plants’ emissions of BOD5 in Montevideo, Uruguay. Results suggest that monitoring and enforcement activity by formal regulators did not have an important deterrent effect on reported BOD5 levels and the compliance status of the industrial plants. However, I find that the larger the threat of being inspected by the municipal government after the end of the Industrial Pollution Reduction Plan, the larger the level of reported BOD5 by the plant for that month. This result is consistent with some results of the difference of means tests, which suggest the presence of under-reporting. The municipal government inspections were an effective way of discovering unreported violations, but not enough to deter violations. The low number of fines applied by regulators during the period may explain this fact. 1 Este trabajo recibio Mencion Especial en el Premio Nacional de Economia Prof. Raul Trajtenberg Segunda Edicion (2004) otorgado por la Facultad de Ciencias Sociales de la Universidad de la Republica. 2 I would like to thank Monica Gonzalez, Marcela Secco, Maria Jose Perez del Castillo, Enrique Garino, Hernan Mendez , Alicia Raffaele, Alejandra Benitez, Gerardo Sequeira, Rodrigo Gorriaran, Marisol Mallo, Francisca Perez, Gerardo Balero, Alejandro Cendon, Marcelo J.

Longitudinal conductance of mesoscopic Hall samples with arbitrary disorder and periodic modulations

We use the Kubo-Landauer formalism to compute the longitudinal (two-terminal) conductance of a two-dimensional electron system placed in a strong perpendicular magnetic field and subjected to periodic modulations and/or disorder potentials. The scattering problem is recast as a set of inhomogeneous, coupled linear equations, allowing us to find the transmission probabilities from a finite-size system computation. The results we present are exact for noninteracting electrons within a spin-polarized lowest Landau level: the effects of the disorder and the periodic modulation are fully accounted for. When necessary, Landau level mixing can also be incorporated straightforwardly into the same formalism. In particular, we focus on the interplay between the effects of the periodic modulation and those of the disorder, when the later is dominant. This appears to be the relevant regime to understand recent experiments [S. Melinte et al., Phys. Rev. Lett. 92, 036802 (2004)], and our numerical results are in qualitative agreement with these experimental results. The numerical techniques we develop can be generalized straightforwardly to many-terminal geometries, as well as other multichannel scattering problems.
OPTIMAL LOCATION OF TCSC DEVICE FOR DAMPING OSCILLATIONS

This paper proposes a residue factor method to obtain the optimal location of the Thyristor Controlled Series Capacitor (TCSC) device to damp out the inter-area mode of oscillations. The residue method is base on the facts that it is the product of the mode’s Observability and controllability index of TCSC controllers to the critical mode. The placements of TCSC controllers have been obtained for the base case and for the dynamic critical contingences. Eigen value analyses are used to assess the most appropriate input signals (stabilizing signal) for supplementary damping control of TCSC. The Right-Half Plane zeros (RHP-zeros) and Hankel Singular Value (HSV) is used as tools to select the most receptive signal to a mode of the Interarea oscillation. The effectiveness of the proposed method of placement is demonstrated on practical network of 25 bus south Malaysian Power system.
Overlay Network Assignment in PlanetLab With NetFinder

PlanetLab has been widely used in the networking community to test and deploy user-defined overlays. Serving as a meta testbed to support multiple overlay networks, PlanetLab has significantly lowered the barriers to build new overlays. However, PlanetLab users always face the problem of selecting a set of nodes and interconnecting them to form the desired overlay network. Unfortunately, such a task is usually carried out manually by individual users and sometimes in an ad-hoc manner. In this paper, we develop NetFinder, an automatic overlay network configuration tool to efficiently allocate PlanetLab resources to individual overlays. NetFinder continuously monitors the resource utilization of PlanetLab and accepts a user-defined overlay topology as input and selects the set of PlanetLab nodes and their interconnection for the user overlay. Experimental results indicate that overlay networks constructed by NetFinder have more stable and significantly higher bandwidth than alternative schemes and near optimal available CPU.
A Novel Communication and Radar System for Underground Railway Applications

A system allowing data to be exchanged between two successive trains in a tunnel, while simultaneously measuring the distance between them, would help to optimize train traffic in very long tunnels, without lowering safety standards. A study including both theoretical and experimental phases was conducted to design and optimize such a system and focused on the Channel Tunnel, between France and England, where a minimum range of 5 km is necessary for operational use. A prototype, operating at 2.45 GHz and based on this new concept, produced successful results. Given that this technique would also be useful in any underground rail system, particularly those that are automated, the prototype was also tested on subway lines, in Lille and Paris.
Critical analysis of leadership governance and its implications in the universities: a case study of South African universities

This paper focuses on exploring the leadership governance in universities. The leadership governance creates an environment which is transparent and it incorporates stakeholders that transform the university. The leadership governance faces visible and invisible challenges which calls for experts in different areas of leadership to be incorporated into the structures of the university in order to bring sustainability in the university. The primary data were collected from six traditional universities and three universities of technology in South Africa from the sample of 39 members of senate. The nature of the study is a quantitative study in which Survey Monkey was used for the distribution of questionnaires. The findings of the study indicate that there is a lack of involvement of stakeholders in the processes of reviewing policies and operational issues. The other findings was the use of university members in leadership to promote unity.

High fusion performance from deuterium-tritium plasmas in JET

High fusion power experiments using DT mixtures in ELM-free H mode and optimized shear regimes in JET are reported. A fusion power of 16.1 MW has been produced in an ELM-free H mode at 4.2 MA/3.6 T. The transient value of the fusion amplification factor was 0.95±0.17, consistent with the high value of nDT(0)τEdiaTi(0) = 8.7 × 1020±20% m-3 s keV, and was maintained for about half an energy confinement time until excessive edge pressure gradients resulted in discharge termination by MHD instabilities. The ratio of DD to DT fusion powers (from separate but otherwise similar discharges) showed the expected factor of 210, validating DD projections of DT performance for similar pressure profiles and good plasma mixture control, which was achieved by loading the vessel walls with the appropriate DT mix. Magnetic fluctuation spectra showed no evidence of Alfvenic instabilities driven by alpha particles, in agreement with theoretical model calculations. Alpha particle heating has been unambiguously observed, its effect being separated successfully from possible isotope effects on energy confinement by varying the tritium concentration in otherwise similar discharges. The scan showed that there was no, or at most a very weak, isotope effect on the energy confinement time. The highest electron temperature was clearly correlated with the maximum alpha particle heating power and the optimum DT mixture; the maximum increase was 1.3±0.23 keV with 1.3 MW of alpha particle heating power, consistent with classical expectations for alpha particle confinement and heating. In the optimized shear regime, clear internal transport barriers were established for the first time in DT, with a power similar to that required in DD. The ion thermal conductivity in the plasma core approached neoclassical levels. Real time power control maintained the plasma core close to limits set by pressure gradient driven MHD instabilities, allowing 8.2 MW of DT fusion power with nDT(0)τEdiaTi(0) ≈ 1021 m-3 s keV, even though full optimization was not possible within the imposed neutron budget. In addition, quasi-steady-state discharges with simultaneous internal and edge transport barriers have been produced with high confinement and a fusion power of up to 7 MW; these double barrier discharges show a great potential for steady state operation. © 1999, Euratom
Change Orders Ordeal: The Output of Project Disintegration

Change orders are one of the most controversial issues in construction contracts and require successful negotiations to avoid claims and possible litigation. Contractors, owners and architects behave differently when dealing with change orders. The aim of this paper is to demonstrate that change orders are the natural result of the disintegration of design and construction, which started in the US in 1893 with a Congressional Act formally separating the design and construction phases of a capital project . Delivery methods such as Design-Build (DB) and Construction Management at Risk (CMR), which are designed to mend the missing integration of design and construction and, consequently, eliminate the existence of change order conflict are proposed to recover the level of integration that existed at the time of the master builder.
