THE EFFECT OF MULTIPHASE NUTRITION ON PRODUCTION PERFORMANCES OF BROILERS

Multiphase broiler nutrition is important from the standpoint of nutrition optimization, economical efficiency of production and protection of the environment. Objective of research is to investigate the effect of multiphase nutiriton, i.e. different mixtures used in broiler nutrition, whse protein content has been reduced in several phases during first fattening stage, on production performances of broilers. Investigation was carried out on 608 individually tagged male chickens, Ross 308 strain, divided into 4 groups: T1 (control group) - nutrition with mixture containing 23% of protein from 1-21 st day; T2 - nutrition with mixture containing 23% of protein from 1 st to 7 th day, and from 7 th to 21 st day diet containing 21.5% protein; T3 - nutrition with mixture containing 23% of protein from 1 st to 14 th day and from 14 th to 21 st day diet containing 21.5% protein and T4 - nutrition with mixture containing 23% of protein from 1 st to 3 rd day, from 4-6 th day with 22.55% protein, 7-9 th day with 22.10% protein, 10-12 th day diet with 21.65% protein, 13 - 15 th day with 21.20% protein, 16-18 th day with 20.75% protein and 19 th -21 st day diet with 20.30% protein. Main production parameters were registered during the trial period (from 1 to 21 st day). Through processing of obtained data it ewas established that chickens of the T4 group (2092.42g), had realized statistically significantly higher body mass compared to T2 (2025.00g) and T3 (2020.07g), but not in relation to control group T1 (2055.16g), during trial period of 42 days. Also, it can be concluded that in regard to daily gain in period up to 21st day, no statistically significant differences between trial groups were established, however, for the entire trial period, average daily gain of chickens in T4 group (48.84g) was statistically considerably higher compared to T2 (47.24g) and T3 (47.13g), whereas in relation to T1 no differences were established T1 (47.99). Feed conversion differed between groups, precisely in favor of the application of multiphase broiler nutrition, i.e. feed conversion of the trial group T4 (1.870) was the best compared to T1 (1.918), T2 (2.005) and T3 (1.970). Based on obtained results it can be concluded that multiphase nutrition had effect on production performances, primarily level of food utilization.

A DSGE Model with Endogenous Term Structure

In this paper, we propose a DSGE model with the term structure of interest rates drawing on the framework introduced by Andres et al. (2004) and Marzo et al. (2008). In particular, we reproduce segmentation in financial markets by introducing bonds of different maturities and bond adjustment costs non-zero at the steady state, introducing a structural liquidity frictions among bonds with different maturities: agents are assumed to pay a cost whenever they trade bonds. As a result, the model is able to generate a non-zero demand for bonds of different maturities, which become imperfect substitutes, due to differential liquidity conditions. The main properties of the model are analysed through both simulation and estimation exercises. The importance of the results are twofold. On one hand, the calibrated model is able to replicate the stylized facts regarding the yield curve and the term premium in the US over the period 1987:3-2011:3, without compromising its ability to match macro dynamics. On the other hand, the estimation, besides providing an empirical support to the theoretical setting, highlights the potentialities of the model to analyze the term premium in a microfounded macro framework. The results match very closely the behavior of actual yields, reflecting the recent activity of the Fed on longer maturities bonds.
MWCNTs synthesis from butanol, diethyl ether, ethyl acetate and hexane by chemical vapor deposition with a stainless steel core as catalyst

A stainless steel core catalyst with several green precursors, butanol, diethyl ether, ethyl acetate and hexane, were used to obtain multi-walled carbon nanotubes via chemical vapor deposition. Argon was used as carrier gas at 50-90 ml/min rates. Samples were synthetized at 680-850 oC, according to the precursor used. The characterization techniques were scanning electronic microscopy, X-ray diffraction, energy dispersive, Fourier transformed infrared and Raman spectroscopy. The micrographs showed tangled carbon nanotubes formation with different diameters from 50-300 nm. Elemental analysis indicated carbon atomic percentages ranging from 93-99 %, 1.0-4.5 % iron and less than 1% of manganese, chrome and silicon. X-Ray diffraction demonstrated the characteristic carbon nanotubes peak (002) at 26°. G and D carbon nanotubes distinctive bands were confirmed by Raman spectra for all samples.
Pathogenic bacteria in turkey meat : A review 1 Bactérias patogênicas em carne de peru : uma revisão

Besides the advances in the adoption of programs regarding food safety and control, the surveillances system still have been reporting the occurrence of foodborne diseases (FBD) in developed and developing countries, and turkey meat is often involved in outbreaks affecting a large amount of human beings annually. Bacteria are responsible by more than 66% of cases of FBD resulting in hospitalizations and highlighting the importance of Salmonella spp. , Campylobacter sp. , Escherichia coli, Listeria monocytogenes, Staphylococcus spp. , Clostridium botulinum and Clostridium perfringens. The contamination sources of turkey carcasses are similar to poultry, however; the reports regarding the involvement of turkey meat in FDB and its risk to public health is rare. Thus, this review focused on identify the microorganisms reported in turkey meat’s outbreaks and their risk factors and mainly contamination sources, as well the limitations to study their epidemiology from farm to consumers. A high-risk was attributed to the genus Salmonella spp. , Escherichia coli, Staphylococcus spp. and Campylobacter sp. , and the latest is considered as neglected in developing countries. This study shown the need of a higher incentive to researches regarding the sanitary conditions of turkey meat processed in Brazil, as well as the need of monitoring this meat sold in the country.
Switching characteristics of a 4H-SiC IGBT with interface defects up to the nonquasi-static regime

The switching characteristics of a 4H-SiC IGBT with interface defects are analyzed up to the nonquasi-static (NQS) regime using reported interface density measurements and device simulation. A threshold voltage shift and current degradation are observed under quasi-static (QS) condition. At fast switching, the trapping effect is observed as a surge of current at the initial gate voltage switch-on, and the NQS behavior itself conceals the trapping effect.
Social Security and Migration with Endogenous Skill Composition

The paper investigates the impact of international migration on public pay-as-you-go pension systems. It first develops a theoretical framework to analyse the effects of migration on the labour market. The model allows for heterogeneity across individuals and for migration to affect both the wages and the educational choice in the recipient country. It then explicitly focuses on social security, under alternative migration scenarios. The analysis shows that migration helps the financial sustainability of the social security scheme, by reducing the elderly dependency ratio. However, it also highlights the complex inter and intragenerational redistributive conflicts caused by the interaction between migration and pension schemes. Migration influences the preferences of residents on social security: it is shown that migration polarises the preferences over the social security scheme and it can undermine the support to it. Social security affects the attitudes of residents towards migration: namely, it decreases the opposition to migration, by working as an insurance device for the unskilled workers.
Analysis of exerted stresses of final drive in MF 285 tractor by Theoretical and Finite Element Method (FEM)

Gears is a rotating cylindrical wheel having tooth cut on it and which meshes with another toothed part to transmit the power or torque. In this investigation, at first, bending stress and contact stress between sun gear and planet gear tooth were determined using of Lewis and Hertzian equations. Afterward, a 3D model of final drives gear was investigated via FEM method. According to the obtained results, maximum of bending stress and contact stress occurred in Gear 1 and low status of helping gear, according to the results that given in the table 3, maximum bending stress using of theoretical and FEM simulation methods were obtained 918.62 Mpa and 951.82 Mpa, respectively. Also, maximum contact stress in same status using of theoretical and FEM simulation methods were obtained 2952.71 Mpa and 2903.20 Mpa, respectively. The percentage difference between the theoretical and FEM bending stress results and contact stress results are of average 3.48% and 11%, respectively, which are still acceptable. As regards, some parameters are ignored in theoretical calculation such as: radial forces in Lewis equation and tangential forces in Hertzian equation, FEM simulation results are acceptable than theoretical results.
Interannual variability of soybean yield in the Argentine Pampas and its relationship with synoptic weather types in Southern South America

The Humid Pampas covers the country's most productive agricultural land where soybean is one of the most important grain crops followed by maize, wheat and sunflower. Persistent synoptic conditions or larger scale events frequently occur in the region, causing extreme rainfall (Malaka and Nuñez, 1980; Casarin and Kousky, 1986; Minetti and Sierra, 1989; Alessandro, 1996, 2000; Labraga et al., 2002). Local daily scale variables that influence soybean yield directly depend on the larger scale atmospheric fields. Compagnucci and Vargas (1985, 1986), Compagnucci and Salles (1997) and Compagnucci et al. (2001) studied the objective identification and classification of synoptic patterns in southern South America and described spatial patterns using surface pressure. Solman and Menendez (2003) and Bischoff and Vargas (2003, 2006) used geopotential heights at the 500 hPa level while Bettolli et al. (2005 (Brazil), 2006) worked on the 1000 hPa level. These authors (2007) made a classification of geopotential height patterns at two levels (1000 and 500 hPa) and studied their relation to rainfall in the Humid Pampas. However, though the studies mentioned analysed the relationship of synoptic structures to different surface variables, no studies have been found relating these structures with any productive sector in particular using its relation to surface variables. The main goal of the present study is to analyse soybean yield variability in the Argentine Humid Pampas in relation to the atmospheric circulation patterns in southern South America. This study is proposed as a continuation of a research line whose main goal is the evaluation and quantification of the impact of climate variability on soybean production. It started with the detailed analysis of the spatial and temporal variability of soybean production in the Argentine Humid Pampas and quantified associations between soybean yield and climate variables (Penalba et al. 2007).
Transmission photometry of WASP-12b: simultaneous measurement of the planetary radius in three bands

Transmission spectroscopy has been successfully used from both the ground and in space to characterize the atmospheres of transiting exoplanets. This technique is challenging from the ground because ground-based spectrographs tend not to be designed to be photometrically stable, and effects such as variable slit losses cause significant systematic uncertainties. An alternative approach is to use simultaneous photometric observations in multiple wavebands to determine wavelength-dependent transit depth differences. We report an application of this technique to one of the hottest known exoplanets, WASP-12b, using the triple-beam camera ULTRACAM. We obtained simultaneous light curves in Sloan u � , and two narrow-band filters centred on 4169 and 6010 A, with full widths at half-maximum 52 and 118 A, respectively. We fit these light curves with a photometric model and determine the planetary radius in the three different bands. Our data show no evidence for a difference in planetary radius over the wavelength range we study, and are consistent with an atmosphere that is dominated by Rayleigh scattering from a high-altitude haze, as well as more complicated atmosphere models which include the effects of molecules such as TiO. Our planetary radius measurements have an average precision of 2.6 per cent, compared to the ∼1.4–2.4 per cent radius differences predicted by the models over this wavelength range. We also find a consistent time of ingress and egress across our three wavebands, in contrast to the early ingress which has been reported for this system at shorter wavelengths.
ENTRYWISE EIGENVECTOR ANALYSIS OF RANDOM MATRICES WITH LOW EXPECTED RANK.

Recovering low-rank structures via eigenvector perturbation analysis is a common problem in statistical machine learning, such as in factor analysis, community detection, ranking, matrix completion, among others. While a large variety of bounds are available for average errors between empirical and population statistics of eigenvectors, few results are tight for entrywise analyses, which are critical for a number of problems such as community detection. This paper investigates entrywise behaviors of eigenvectors for a large class of random matrices whose expectations are low-rank, which helps settle the conjecture in Abbe et al. (2014b) that the spectral algorithm achieves exact recovery in the stochastic block model without any trimming or cleaning steps. The key is a first-order approximation of eigenvectors under the ℓ ∞ norm: u k ≈ A u k * λ k * , where {u k } and { u k * } are eigenvectors of a random matrix A and its expectation E A , respectively. The fact that the approximation is both tight and linear in A facilitates sharp comparisons between u k and u k * . In particular, it allows for comparing the signs of u k and u k * even if ‖ u k - u k * ‖ ∞ is large. The results are further extended to perturbations of eigenspaces, yielding new ℓ ∞-type bounds for synchronization ( ℤ 2 -spiked Wigner model) and noisy matrix completion.
Solubility and reactivity of HNCO in water: insights into HNCO's fate in the atmosphere

Abstract. A growing number of ambient measurements of isocyanic acid (HNCO) are being made, yet little is known about its fate in the atmosphere. To better understand HNCO's loss processes and particularly its atmospheric partitioning behaviour, we measure its effective Henry's Law coefficient KHeff with a bubbler experiment using chemical ionization mass spectrometry as the gas phase analytical technique. By conducting experiments at different pH values and temperature, a Henry's Law coefficient KH of 26 ± 2 M atm−1 is obtained, with an enthalpy of dissolution of −34 ± 2 kJ mol−1, which translates to a KHeff of 31 M atm−1 at 298 K and at pH 3. Our approach also allows for the determination of HNCO's acid dissociation constant, which we determine to be Ka = 2.1 ± 0.2 × 10−4 M at 298 K. Furthermore, by using ion chromatography to analyze aqueous solution composition, we revisit the hydrolysis kinetics of HNCO at different pH and temperature conditions. Three pH-dependent hydrolysis mechanisms are in play and we determine the Arrhenius expressions for each rate to be k1 = (4.4 ± 0.2) × 107 exp(−6000 ± 240∕T) M s−1, k2 = (8.9 ± 0.9) × 106 exp(−6770 ± 450∕T) s−1 and k3 = (7.2 ± 1.5) × 108 exp(−10 900 ± 1400∕T) s−1, where k1 is for HNCO + H++ H2O → NH4++ CO2, k2 is for HNCO + H2O → NH3 + CO2 and k3 is for NCO−+ 2 H2O → NH3+ HCO3−. HNCO's lifetime against hydrolysis is therefore estimated to be 10 days to 28 years at pH values, liquid water contents, and temperatures relevant to tropospheric clouds, years in oceans and months in human blood. In all, a better parameterized Henry's Law coefficient and hydrolysis rates of HNCO allow for more accurate predictions of its concentration in the atmosphere and consequently help define exposure of this toxic molecule.
Picard–Lefschetz theory and dilating ℂ*‐actions

We consider C* ‐actions on Fukaya categories of exact symplectic manifolds. Such actions can be constructed by dimensional induction, going from the fibre of a Lefschetz fibration to its total space. We explore applications to the topology of Lagrangian submanifolds, with an emphasis on ease of computation.
ICT-supported, scenario-based learning in preclinical veterinary science education: Quantifying learning outcomes and facilitating the novice-expert transition

Problem and/or scenario-based learning is often deployed in preclinical education and training as a means of: (a) developing students' capacity to respond to authentic, real-world problems; (b) facilitating integration of knowledge across subject areas, and; (c) increasing motivation for learning. Six information and communication technology (ICT) supported, scenario-based learning (SBL) problems using case studies that integrated information across subject areas were implemented in a second-year genetics course for undergraduate veterinary science students and linked to educational outcomes. On a post-implementation questionnaire, students appreciated the use of authentic scenarios but login records indicated variable engagement among students. Comparison of learning outcomes from SBL-supported and non-SBL-supported content (within and across student cohorts) indicated that exposure to SBL generated quantifiable improvements in learning in both high and low ability students. Despite this, students did not perceive that the SBL activities improved their learning. Thus, ICT-supported SBL have the potential to reinforce connectivity of content across a range of pre-clinical courses, but to facilitate a genuine novice to expert transition may require consideration of students' perceptions of scenario relevance, their confidence, and how students of differing learning styles engage with such activities.
Measuring a Quantum System’s Classical Information

In the governing thought, I find an equivalence between the classical information in a quantum system and the integral of that system’s energy and time, specifically , in natural units. I solve this relationship in four ways: the first approach starts with the Schrodinger Equation and applies the Minkowski transformation; the second uses the Canonical commutation relation; the third through Gabor’s analysis of the time-frequency plane and Heisenberg’s uncertainty principle; and lastly by quantizing Brownian motion within the Bernoulli process and applying the Gaussian channel capacity. In support I give two examples of quantum systems that follow the governing thought: namely the Gaussian wave packet and the electron spin. I conclude with comments on the discretization of space and the information content of a degree of freedom.
Brearleyite, Ca_(12)Al_(14)O_(32)Cl_2, a new alteration mineral from the NWA 1934 meteorite

Brearleyite (IMA 2010-062, Ca_(12)Al_(14)O_(32)Cl_2) is a Cl-bearing mayenite, occurring as fine-grained aggregates coexisting with hercynite, gehlenite, and perovskite in a rare krotite (CaAl_2O_4) dominant refractory inclusion from the Northwest Africa 1934 CV3 carbonaceous chondrite. The phase was characterized by SEM, TEM-SAED, micro-Raman, and EPMA. The mean chemical composition of the brearleyite is (wt%) Al_2O_3 48.48, CaO 45.73, Cl 5.12, FeO 0.80, Na_2O 0.12, TiO_2 0.03, –O 1.16, sum 99.12. The corresponding empirical formula calculated on the basis of 34 O+Cl atoms is (Ca_(11.91)Na_(0.06))Σ_(11.97)Al_(13.89)Fe_(0.16)Ti_(0.01))Σ_(14.06)O_(31.89)Cl_(2.11). The Raman spectrum of brealryeite indicates very close structural similarity to synthetic Ca_(12)Al_(14)O_(32)Cl_2. Rietveld refinement of an integrated TEM-SAED ring pattern from a FIB section quantifies this structural relationship and indicates that brearleyite is cubic, ⌈43d; a = 11.98(8) A, V = 1719.1(2) A3, and Z = 2. It has a framework structure in which AlO4 tetrahedra share corners to form eight-membered rings. Within this framework, the Cl atom is located at a special position (3/8,0,1/4) with 0.4(2) occupancy and Ca appears to be disordered on two partially occupied sites similar to synthetic Cl-mayenite. Brearleyite has a light olive color under diffuse reflected light and a calculated density of 2.797 g/cm3. Brearleyite is not only a new meteoritic Ca-,Al-phase, but also a new meteoritic Cl-rich phase. It likely formed by the reaction of krotite with Cl-bearing hot gases or fluids.
