EFECTO DEL PASTOREO MIXTO Y MONOESPECÍFICO EN UNA PRADERA DE ALFALFA-OVILLO EFFECT OF MIXED AND SINGLE GRAZING ON AN ALFALFA-ORCHARD PASTURE

The present study was carried out in order to evaluate on-offer and residual forage of alfalfa (Medicago sativa)-orchard grass (Dactylis glomerata) pasture in the summer-fall period, subjected to three types of rotational grazing: a) mixed with heifers and ewe-lambs; b) heifers only; c) ewe lambs. The experimental design was completely randomized with an arrangement of split plots and four replications; the experimental unit was a pasture. The main plot was grazing type and the sub-plot grazing period. Stocking rate was equal in the three grazing types, with 1 d of occupation and 30 d rest; three grazing periods were evaluated. The amount of on-offer and residual forage varied (p≤0.05) with grazing type and period; ewe lambs grazing had the lowest values and mixed grazing showed intermediate values. The latter presented 24% less (p≤0.05) residual forage in areas contaminated with heifer feces than grazing with heifers only. It was concluded that the grazing type influenced on some characteristics of alfalfaorchard grass pasture, and mixed grazing promoted a more homogenous harvest than grazing with heifer only, due to lower rejection of dung-contaminated forage.

The Characteristics of a Successful EFL Teacher in the Learners’ eyes

There are two major interrelated reasons behind examining the topic of this paper. In fact, even after many years of their learning English as a foreign language, a large number of secondary school students’ level of proficiency in the language is so low that they cannot use it communicatively, and cannot major in it at university, either. Accounting for their underachievement, a large percentage of such students claim that many teachers still play traditional roles in the teaching-learning process, which has contributed to the problem. The main purpose of this paper, therefore, is to explore the extent to which such a claim is justifiable. In this frame of reference, a questionnaire was administered to a certain number of students on the extent to which the teacher is responsible for the issue, as well as what they personally think the key characteristics of a successful EFL teacher are. Along with this, the paper will equally look at other qualities that ought to be available in EFL teachers with the overall aim of helping them to do their job successfully, and hence attain the expected learning results.
PATERNITY LEAVE AND FATHERS’ INVOLVEMENT WITH THEIR YOUNG CHILDREN

Unlike many European countries, the US has no national paternity leave policy giving fathers the right to take paid time off work following the birth (or adoption) of a child. Despite this, prior research suggests that many fathers do take some time off work after a child is born. However, little is known about the determinants, circumstances or consequences of paternal leave-taking. In this paper, we use the first wave of data from the Early Childhood Longitudinal Study–Birth Cohort (ECLS–B), a new nationally representative panel study of over 10,000 children born in 2001, to examine these questions. We make use of ECLS–B questions asked directly of resident fathers pertaining to their participation in a range of child care-taking activities, as well as a rich set of measures about the father, mother and child. We find that the overwhelming majority of fathers take at least some leave at the birth of their child, but that the length of that leave varies a good deal. Our results also indicate that fathers who take longer leave are more involved in child care-taking activities nine months later.
Optimal Taxation in a Limited Commitment Economy

This paper studies optimal Ramsey taxation when risk sharing in private insurance markets is imperfect due to limited enforcement. In a limited commitment economy, there are externalities associated with capital and labor because individuals do not take into account that their labor and saving decisions affect aggregate supply, wages and thus the value of autarky. Due to these externalities, the Ramsey government has an additional goal, which is to internalize the externalities of labor and capital to improve risk sharing, in addition to its usual goal - minimizing distortions when financing government expenditures. These two goals drive capital and labor taxes in opposite directions. By balancing these conflicting goals, the steady-state optimal capital income taxes are levied only to remove the negative externality of the capital, and optimal labor income taxes are set to meet the budgetary needs of the government in the long run, despite positive externalities of labor.
For Whom is MAI ? A theoretical Perspective

Why do we observe some LDCs objecting the prospect of a Multilateral Agreement on Investment (MAI), although they have been keen to liberalize investment in preferential agreements in recent years? In this paper, we analyse the issue of MAI implementation and assess the welfare consequences of such kind of agreements. In our model, participation to MAI involves a trade-o¤ between less rent extraction from multinational . rms (MNEs) and more abundant FDI in‡ows. At equilibrium, either all countries enter MAI, or all countries stay out, or only some of them enter. Coordination problems may induce multiple equilibria: the three types of equilibria may coexist. So, the implementation of MAI may depend not only on structural factors but also on the general ”political climate”. When all countries join MAI, world welfare is maximized because this minimizes the hold-up problem faced by MNEs and stimulates investment. However, in an asymmetric world, welfare gains are not guaranteed for all countries. JEL Reference: F13, F23. , O19.
Evaluating the political organisation of Muslim citizens in the Netherlands: The role of political orientation, education and multiculturalism

Political participation is an important aspect of the integration of Muslim citizens into western societies. However, Muslims’ formal political participation is often met with resistance from the majority population. In two studies, we investigated among national samples of majority Dutch whether the level of resistance to the democratic political organizations of Muslim citizens is associated with political orientation and level of education. Furthermore, we examined whether these associations are mediated by the endorsement of multiculturalism. Findings from both studies show that the higher educated and politically left-wing individuals are more supportive of Muslim political organisation and that this association is (partly) explained by the endorsement of multiculturalism. Additionally, in Study 2 it is found that attitudes toward cultural tradition and group equality mediate the relations between education and political orientation with multiculturalism.
Modelling the compact jet in MAXI J1836-194 with disc-driven shocks

The black hole candidate MAXI J1836-194 was discovered in 2011 when it went into an outburst, and was the subject of numerous, quasi-simultaneous, multi-wavelength observations in the radio, infrared, optical, and X-rays. In this paper, we model its multi-wavelength radio to optical spectral energy distributions (SEDs) with an internal shock jet model (ishem; Malzac 2014). The jet emission is modelled on five dates of the outburst, during which the source is in the hard and hard intermediate X-ray spectral states. The model assumes that fluctuations of the jet velocity are driven by the variability in the accretion flow which is traced by the observed X-ray timing properties of the source. While the global shape of the SED is well reproduced by this model for all the studied observations, the variations in bolometric flux and typical energies require at least two parameters to evolve during the outburst. Here, we investigate variations of the jet power and mean Lorentz factor, which are both found to increase with the source luminosity. Our results are compatible with the evolution of the jet Lorentz factor reported in earlier studies of this source. However, due to the large degeneracy of the parameters of the ishem model, our proposed scenario is not unique.
Hadean geodynamics inferred from time-varying 142Nd/144Nd in the early Earth rock record

Tracking the secular evolution of 142Nd/144Nd anomalies is important towards understanding the crust-mantle dynamics in the early Earth. Excessive scatter in the published data, however, precludes identifying the fine structure of 142Nd/144Nd evolution as the expected variability is on the order of few parts per million. We report ultra-high precision 142Nd/144Nd data for Eoarchean and Palaeoarchean rocks from the Isua Supracrustal Belt (SW Greenland) that show a well-resolved 142Nd/144Nd temporal variability suggesting progressive convective homogenisation of the Hadean Isua depleted mantle. This temporally decreasing 142Nd/144Nd signal provides a direct measure of early mantle dynamics, defining a stirring timescale of <250 Myr consistent with vigorous convective stirring in the early mantle. The 142Nd/144Nd evolution suggests protracted crustal residence times of ~1000-2000 Myr, inconsistent with modern-style plate tectonics in the Archean. In contrast, a stagnant-lid regime punctuated by episodes of mantle overturns accounts for the long life-time estimated here for the Hadean proto-crust.
Body orientation for thermoregulation and daily activity cycle of Mabuya macrorhyncha (Squamata: Scincidae)

We investigated the daily activity and thermoregulatory body orientation of Mabuya macrorhyncha (Hoge, 1947), a lizard species that occurs in the Brazilian Atlantic Forest. We conducted this investigation in a sandy coastal dune remnant (“restinga” ecosystem) in Grussaí, state of Rio de Janeiro, Brazil, during the summer. The daily activity cycle of the lizards started around 6:00 am and ended before 7:00 pm. This is longer than observed in other populations of M. macrorhyncha (approximately 7:00 am to 5:00 pm). The activity cycle of the lizards was bimodal, with the first peak between 6:00 and 11:00 am and the second from 2:00 to 7:00 pm. This contrasts with observations on other populations of this species, which revealed an unimodal pattern. The mean body temperature of M. macrorhyncha in Grussaí was 34.2 ± 1.5 °C, which was comparatively higher than observed in other populations of the species. The differences in the daily activity and of body temperature of these lizards between our study and previous studies on this species may reflect environmental thermal conditions. The mean air and mean substrate temperatures when individuals were active were 27.8 and 30.5 °C respectively. Lizard orientation was significantly correlated with the direction of the solar incidence, suggesting that solar radiation, and particularly behavioral adjustments that maximize exposure to the sun, are important for the thermoregulation of M. macrorhyncha. Circular structures at the site, such as bromeliads, offer microhabitats with different orientations to the sunlight, favoring lizard thermoregulatory behaviors.
DEVELOPMENT OF IMMUNO-DIAGNOSTIC ASSAY TO DETECT Cry 2 B PROTEIN

Cry2B as an antigen was used to produce single chain fragment variable (scFv) antibody using phage display technology. M13K07 helper phage was used to infect the Tomlinson scFv library which enabled the display of scFv on their surfaces and this constitutes the phage scFv library. These phages were screened against immobilized cry2B for specific binders. The unbound phages are getting rid of through the process of biopanning. Four rounds of biopanning were conducted, during each biopanning the higher specific binders (phages) were enriched. After fourth round of biopan the scFv specific to cry2B was recovered by infecting phages to E.coli K12. Randomly 45 colonies were selected for monoclonal ELISA, two colonies showed highest reading viz., pSNM15 and pSNM29. The selected clones were sequenced with LMB3 forward and pHEN reverse primer and characterized. Both the clones have similar conserved domains in Ig super family. The homology search with BLASTn algorithm indicated 93% homology over Homo sapiens chromosome 2 genomic contig and BLASTp algorithm indicated 98% homology over anti-TREM-like transcript-1 antibody [synthetic construct]. Single chain antibody fragments of pSNM15 and pSNM29 were subcloned into pQUANTabody expression vector which enabled transcriptionally fuse with scFv monoclonal antibody fragment and the gene coding for bacterial alkaline phosphatase (PhoA) enzyme. Upon expression of clone, it has produced fusion protein of ALP along with pSNM15 and pSNM29 monoclonal antibody. The scFv-ALP conjugate has been produced against Cry2B protein. Using this antibody conjugate, a detection assay was developed. The assay was efficient to detect to the cry2B protein at the concentration of 800 ng/ml and it was also cross checked with other proteins to evaluate the specificity of monoclones raised against Cry2B.
Ocean Wave Non-Linearity and Wind Input in Directional Seas: Energy Input During Wave-Group Focussing

There has been speculation that energy input (wind) can play an important role in the formation of rogue waves in the open ocean. Here we examine the role energy input can play by adding energy to the modified non-linear Schrödinger equation. We consider NewWave type wave-groups with spectra which are realistic for wind waves. We examine the case where energy input is added to the group as the wave-group focuses. We consider whether this energy input can cause significant non-linear effects to the subsequent spatial and spectral evolution. For the parameters considered here we find this to have only a small influence.
Using angular dependence of multibeam echo features in seabed classification

The approach to seabed classification based on processing multibeam sonar echoes is presented. The multibeam sonars, besides their well verified and widely used applications like high resolution bathymetry measurements or underwater object imaging, are also the promising tool in seafloor identification and classification, having several advantages over conventional single beam echosounders. The proposed seabed classification method assumes calculation of a set of parameters of an echo envelope, similarly as in single beam classification. These parameters include echo energy, echo length, statistical moments of echo energy and the set of echo shape descriptors. They are extracted for each consecutive beam allowing the estimation of their dependence on seafloor incident angle. The characteristic features of this dependence are described quantitatively and constitute the input information for an automatic supervised seabed classifier. The results of the simple classification procedure applied for multibeam data records acquired from several bottom types in Gdansk Bay region are presented and discussed.
Proposing a neural network model to predict time and cost claims in construction projects

AbstractDespite broad improvements in construction management, claims still are an inseparable part of many construction projects. Due to huge cases of claim in construction industry, this study argues that claim management is a significant factor in construction projects success. In this study, the most possible causes of these emerging claims are identified and statistically ranked by Probability-Impact Matrix. Subsequently, by classifying claims in different cases, the most important ones are ranked in order to achieve a better understanding of claim management in each project. In this regard, a new index is defined, being able to be applied in a variety of projects with different time and cost values, to calculate the amount of possible claims in each project along with related ratios with respect to the cost and time of each claim. This study introduces a new model to predict the frequency of claims in construction projects. By using the proposed model, the rate of possible claims in each project can.
Nanocomposites of Magnetite and Layered Double Hydroxide for Recyclable Chromate Removal

Nanocomposites containing magnetic iron oxide magnetite nanoparticles and layered double hydroxide LDH nanosheets were prepared by two different methods, exfoliation-reassembly and coprecipitation, for aqueous chromate adsorbent. According to X-ray diffraction, scanning electron microscopy, and atomic force microscopy, both nanocomposites were determined to develop different nanostructures; LDH nanosheets well covered magnetite nanoparticles with house-of-cards-like structure in exfoliation-reassembly method, while coprecipitation resulted in LDH particle formation along with magnetite nanoparticles. Zeta-potential measurement also revealed that the magnetite surface was effectively covered by LDH moiety in exfoliation-reassembly compared with coprecipitation. Time, pH, concentration dependent chromate adsorption tests, and magnetic separation experiments exhibited that both nanocomposites effectively adsorb and easily collect chromate. However, exfoliation-reassembly nanocomposite was determined to be slightly effective in chromate removal by ~10%. Chromate adsorbed nanocomposites could be regenerated by treating with bicarbonate and the regenerated nanocomposites preserved ~80% of chromate adsorption efficacy after three times of recycling.
Manual reaction speed and manual dexterity in elderly people: A comparative study between elderly practitioners and non-practitioners of physical activity

The human being, as years go by, transforms and loses their normal movement abilities, like too quickly react and objects manipulate. Most of the epidemiological evidence argues that when a subject adopts an active lifestyle through physical activity (PA), this minimizes the effects of the aging process and improves their capabilities. To assess the influence of PA in manual reaction speed (MRS) and manual dexterity (MD) we applied The Nelson Hand Reaction Test and The Minnesota Manual Dexterity Test (the placing and turning tests), respectively. The sample consisted of 40 volunteers (between 67 and 85 years old) residents in two elderly institutions of the Porto city and they were divided into 2 groups, one by practitioners of PA and the other by non-practitioners (with 20 subjects respectively). This study had these conclusions: 1/Concerning to manual reaction speed (MRS): (i) there are statistically significant differences between practitioners and non- practitioners of PA, as well as between genders, and between males-practitioners and males non- practitioners of PA; (ii) between female practitioners and female non-practitioners of PA there weren’t any significant differences; 2/ Concerning to the manual dexterity (MD) it was verified that: (i) either in placing or in turning tests, there are statistically significant differences between practitioners and non-practitioners of PA, and equally there are differences between practitioners and non-practitioners of PA in each gender; (ii) between genders, in the placing test, they observed differences with statistical significance, but in the turning test these differences were only verified in the third and fourth issues, and in the average of four issues.
Morphometric evaluation, by ultrasonographic exam, of the portal vein, caudal vena cava and abdominal aorta in healthy dogs of different body weights.

The diameters and areas of portal vein, caudal vena cava and abdominal aorta are useful measurements in dogs. These values can be easily measured by ultrasonographic exam, and variations of normality can be an important indicator of hepatic or extra-hepatic alterations. This study aimed to measure the diameter and areas of portal vein, caudal vena cava and abdominal aorta in healthy dogs, with normal corporal score, divided in groups according to the body weight, and assess whether the data are influenced by animal weight. Thirty dogs were examined and divided into three groups (Group A: ≤ 10 kg Group B: from 10.1 to 20.0 kg; Group C: ≥ 20.1 kg). To measure the diameters and areas of portal vein, caudal vena cava and abdominal aorta, the animal was kept in left lateral decubitus position and the transducer was placed on the right lateral abdominal wall, at approximately the 10 th or 11 th intercostal space, in the porta hepatis region. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta were significantly lower for dogs in Group A with respect to other groups and the dogs from Groups B and C had similar results with each other. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta may vary with the animal size, and reference values must be specific for small, medium and large dogs.
