Epidemiological aspects and treatment of parasitic lesions similar to Stephanofilariasis disease in nursing cows.

The aim was to describe epidemiological, clinical and histological aspects of parasitic lesions caused by Stephanofilariasis on the udder of nursing cows and to evaluate the viability of a therapeutic protocol. Forty lactating cows with characteristic Stephanofilariasis lesions were divided into two groups, GI and GII. The wounds on the udder of the GI cows were cleansed with sodium hydrochloride and treated topically with an ointment consisting of trichlorphone, ivermectine, dexamethasone, calendula, zinc oxide and an adherent ointment of sodium vaseline, associated with the parenteral application of 1% ivermectine. GII served as control group and was left untreated. Twelve cows (60%) of GI had recovered on the 45 th day of treatment and 8 cows (40%) showed clinical cure within 45-60 days. The diagnosis of Stephanofilaria stilesi infection is generally presumptive. Epidemiologically-related aspects, clinical findings and positive response to treatment help to confirm the disease. Histopathological exams also assist in the diagnosis when the presence of nematodes can be revealed, although this finding is not frequent. The therapeutic protocol employed proved to be economically viable and efficient, with recovery of all the lesions.

Nitrogen deposition and plant biodiversity: past, present, and future

Reactive nitrogen (N) deposition from intensive agricultural and industrial activity has been identified as the third greatest threat to global terrestrial biodiversity, after land-use and climate change. While the impacts of N deposition are widely acknowledged, their magnitude is poorly quantified. We combine N deposition models, empirical response functions, and vegetation mapping to simulate the effects of N deposition on plant species richness from 1900 to 2030, using the island of Great Britain as a case study. We find that current species richness values – when averaged across five widespread habitat types – are approximately one-third less than without N deposition. Our results suggest that currently expected reductions in emissions will achieve no more than modest increases in species richness by 2030, and that emissions cuts based on habitat-specific “critical loads” may be an inefficient approach to managing N deposition for the protection of plant biodiversity. The effects of N deposition on biodiversity are severe and are unlikely to be quickly reversed.
A Study of Real Time Simulation of Grasping in User-Product Interaction

Customer evaluation of concepts plays an important role in the design of handheld devices, bottles of douche gel and shampoos, where the phenomenon of grasping needs to be evaluated. In these applications important information on the aspects of ergonomics and user behaviours could be gathered from computer simulation. As in all computer simulation, a trade-off between the fidelity of simulation and the computation time is required on the other hand, in order to achieve real time evaluation of design solutions. This paper reviews the literature of computer simulation methods that are used in simulating the most representative physical phenomena of human product interaction. The paper addresses the following research questions: Which geometric and material representations can be used for simulating particular physical phenomena and how these representations can be used in combined simulation? How the accuracy of simulation is influenced by the computational method and by the geometric representation? What simplifications are applied in order to achieve real time computation? The paper gives a critical analysis on the influence of various geometric representations (i.e. rigid body, surface mesh, solid mesh, and particle systems) on the performance and accuracy of simulation of different physical phenomena of grasping. In addition it presents open issues in research of grasping simulation for user-product interaction.
Blood profiles of indigenous Pedi goats fed varying levels of Vachellia karroo leaf meal in Setaria verticillata hay-based diet

Vachellia karroo ( Acacia karroo ) is promising fodder for goats in the critical dry season in communal rangelands. The only limitation to the use of this fodder tree is the presence of phenolic compounds, such as condensed tannins. A study was conducted to investigate the effects of tanniniferous V. karroo leaf meal feeding on blood profiles of indigenous Pedi goats fed a basal diet of Setaria verticillata grass hay. Twenty indigenous Pedi goats, weighing 18 ± 2 kg, were allocated in a completely randomized design to five dietary treatments containing V. karroo leaf meal at 20% (S 80 A 20 ), 25% (S 75 A 25 ), 30% (S 70 A 30 ), 40% (S 60 A 40 ) and 50% (S 50 A 50 ) of the total diet in a 22-day trial. Twelve ml of blood were collected from the jugular vein from each goat before and after the experiment for haematological and serum biochemical assays. Daily dry matter intake (DMI) was similar across treatments, ranging from 633 g to 765 g per goat per day. There was no difference in initial and final bodyweights of goats consuming various experimental diets. However, bodyweight gains were significantly higher in goats fed a diet with 50% leaf meal as compared with other treatment groups. There were no differences in haematological indices of Pedi goats except for mean corpuscular haemoglobin (Hb) concentration. Goats fed 50% leaf meal had significantly lower mean corpuscular haemoglobin concentration (MCHC) values as compared with other treatment groups. Similarly, there were no differences in the blood serum chemistry of goats that consumed various inclusion levels of V. karroo , except for serum total protein (TP) and alanine aminotransferase (ALT). Goats fed 50% leaf meal had depressed serum TP, while serum enzyme Alanine aminotransferase (ALT) concentration decreased significantly in goats fed 25% leaf meal as compared with those on the 20% dietary treatment. Tannin concentration of 8.2 g/kg dry matter (DM) had no toxic effect on experimental animals. A 40 % inclusion of V. karroo in a Setaria verticillata hay-based diet may be fed to indigenous Pedi goats without compromising the immunity system and health of the animals.

Validation of GOCE Gravity Field Models in Germany

The fifth release of global gravity field models (GGMs) from the GOCE mission published in mid-2014 are based on observation data from the whole mission lifetime. High precision gravity field data sets in Germany are utilized to validate the GOCE GGMs of the fourth and fifth release processed by the time-wise (TIM) and the direct approach (DIR) as well as their internal uncertainty estimates. The comparisons are performed between EGM2008 and the GOCE GGMs up to spherical harmonic degree and order (d/o) 200 in terms of quasigeoid heights, gravity anomalies and vertical deflections. For the comparisons of GPS/levelling data and astrogeodetic vertical deflections with the GOCE GGMs, the different spectral characteristics of the data sets are considered by modelling the high frequency signals above d/o 200 by EGM2008 and detailed topographic information within the residual terrain model (RTM) approach. The RMS differences of all comparisons are introduced as observations within a least squares adjustment in order to estimate the commission errors of the GOCE GGMs as well as the uncertainties from all other terms involved in the comparisons, i.e. EGM2008, RTM effects and GPS/levelling. The commission errors of the fifth release GOCE GGMs up to d/o 200 are estimated to 2.5 cm and 2.4 cm for TIM5 and DIR5, respectively, as well as 0.66 mGal and 0.10′′ for both models in terms of quasigeoid heights, gravity anomalies and vertical deflections, respectively. This is in good agreement with the formal error degree variances of TIM5, while for DIR5 a factor of 3 is proposed. Moreover, both fifth release GOCE GGMs show significant improvements of approx. 30% compared to their predecessors.
How do students self-regulate? Review of Zimmerman"s cyclical model of self-regulated learning

The use of learning strategies is crucial for students" academic performance and promoting deeper learning approaches. The self-regulated learning models offer comprehensive theoretical backgrounds. These ena- ble more holistic approaches to the use of learning strategies. In this paper, Zimmerman"s (2000; 2003; Zimmerman & Moylan, 2009) cyclical model of self-regulated learning is described and analysed as one of the most com- prehensive. The model is grounded in social cognitive theory and is com- prised of three phases (forethought, performance and self-reflection) with a special focus on the influences of motivation on self-regulation. The differ- ent processes included in the model are analysed here in detail. Zimmer- man"s framework is considered in relation to other self-regulated learning models in order to recognize its importance in theory and practice.
Warming up and stretching for athletes : A meta-analysis of the research literature from 2000 to 2006 in light of current athletic practice

This review presents the methods used to investigate the effects of various stretching protocols on muscular force and performance, in light of current individual and elite athlete stretching practices in their warm-up routines. A meta-analysis of peer-reviewed articles between the years of 2000 and 2007 revealed the majority of studies support the notion that static stretching is detrimental to muscular force and performance. However, the meta-analysis also revealed that the protocols used do not necessarily match current practice with many elite athletes. This article proposes, based on the mismatch between research and practice, that further studies must address this issue in further exploring the role of stretching in pre-training and competition warm-up routines.
Biometric recognition for twins inconsideration of age variability using PPG signals

Recent biometric modalities involve biomedical signals such as PPG to identify individuals. This study has been motivated by this new research area using PPG signal to identify twins incorporating age variability. The proposed system is suggested to be a substitute to the current traditional methods being used widely nowadays. A total of 21 subjects were used for experimentation purposes and lowpass filter is applied to remove unwanted noise from the signal. Distinctive features are extracted from the filtered PPG signals. Later, Bayes Network (BN), Naive Bayes (NB), Radial Basis Function (RBF) and Multilayer Perceptron (MLP) were used to classify the subjects using the discriminant features. Based on the experimentation results, classification accuracies ranging from 90% to 100% were achieved by categorizing the data into six different sets which are overall dataset, Groups I, II, III, IV and V. The result provides an alternative mechanism to identify twins using PPG signals incorporating age variability besides using the traditional methods.

Antimicrobial, Antifungal & Cytotoxic Activities Screening of Stem Bark Fractions from Terminalia chebula

The fractionated crude extracts and two isolated pure compounds TC-1(Phytol) and TC-2(Stigmasterol) from stem bark of Terminalia chebula were screened for their antibacterial and antifungal activities and cytotoxicity against brine shrimp nauplii. Petroleum ether, ethyl acetate (EtOAc) and methanol (MeOH) extracts and the compounds isolated from EtOAC fractions were studied for their antimicrobial activities. Cytotoxic activities were conducted only with crude extract. Both EtOAc and petroleum ether extract showed promising and moderate antimicrobial activities against most of the gram positive and gram negative bacteria whereas the MeOH extract did not show any antimicrobial activities. The isolated pure compounds TC-1 & TC-2 exhibited activities against most of the bacterial strains. The cytotoxicity towards brine shrimp nauplii of the crude extract was studied. The LC50 values of plant crude extract is found to be 5. 623413µg/mL.
Role of reversal incoherency in reducing switching field and switching field distribution of exchange coupled composite bit patterned media

Model exchange coupled composite media, namely [Co/Pd]5/Pd(t)/[Co/Ni]3/Co multilayers, deposited onto prepatterned substrates have been investigated for potential use in bit patterned recording. Optimizing the thickness of the Pd interlayer allows decreasing the switching field (HC) and switching field distribution (σSFD) while maintaining thermal stability. The dependence of the remanent coercivity on the external field angle indicates that the gain in HC and σSFD originates from the incoherent magnetization reversal introduced by slightly decoupling the hard and soft multilayer stacks. This tendency is confirmed by further reductions in HC and σSFD, when inserting another Pd interlayer within the hard [Co/Pd]5 stack.
A fast method for large-scale isolation of phages from hospital sewage using clinical drug-resistant Escherichia coli

With the continued emergence of multi-drug resistant genes and drug-resistant bacteria, the functions and applications of traditional antibiotics are challenged. Thus, products that can be combined with existing antibiotics or replace them are of great interest to the research and medical communities. As a natural parasite of bacteria, phages have been reconsidered for use in treating super or drug-resistant bacterial infections. The main aim of this study was to isolate new phages from hospital sewage, especially those with broad-spectrum infectivity for the establishment of an Escherichia phage library. According to differences in their infection spectrum, bacteriophages were identified using a plaque method. In total, 18 E. coli phages were isolated from hospital sewage. The characteristics of the wide host spectrum E. coli bacteriophage E12P1 were further studied. Electronic micrographs indicated that phage E12P1 had a cubic symmetry and a long tail. The growth curve suggested the incubation time was 30 min, the burst phase was 20 min, and the burst size was 43. This plaque-forming method could be adopted to isolate E. coli phage easily, rapidly and in large quantities. Among the 18 isolated E. coli phages, 10 of them had a broad host range in E. coli and warrant further study. Key words : Escherichia coli phages, large-scale isolation, drug resistance, biological properties.
Brazil, 1981-2013: the effects of economic growth and income inequality on poverty

This study analyses the impact of economic growth and income inequality on poverty in Brazil in the years from 1981 to 2013. A dynamic panel model was used, estimated by the twostep generalized method-of-moments system developed by Blundell-Bond (1998), in order to analyse three scenarios: the first corresponds to the entire period covered by this study (i.e. 1981-2013); the second encompasses the years from 1981 to 1994 (the period leading up to the Real Plan); and the third is the period from 1995 to 2013 (the years following the implementation of the Real Plan). The results indicate that economic growth policies that promote an increase in income in conjunction with a reduction in income disparities are more effective in combating poverty in Brazil than those that focus only on raising mean income levels. The findings also point to the existence of a pro-poor form of growth in the period following the Real Plan.

after arising. Benjamin and Denny [1] with the vorticity-stream function method to simulate the two-dimensional closed pull hole course and supplemented with multi-grid method, will increase the numerical simulation of the Reynolds number to 104, expressly found that the two-dimensional geometry of a closed pulling hole course located primary vortical center and three times the corner vortical. Koseff and Street [2] employed the experimental data for a series of studies with discussion. Koseff and Street [3] were the top three drivers pulled closed experimental observation point field, when the Reynolds number is between 6000-8000, the structure of the turbulent rotating disk-driven flow for the first time the show. Fenstermacher [4] used laser-Doppler velocimetry explore concentric circles in the middle of the restricted fluid flow from the column transition situations arising from the rotation. Chenoweth and Eyret [5] found that when the Reynolds number is higher than a certain value, the main component of the two-dimensional flow field in the following structure: the geometric center of the vortical in the main (primary eddy), located at the corner of the three sub-swirl (secondary eddy).

Twentieth century constraints on sea level change and earthquake deformation at Macquarie Island

SUMMARY Through the combination of rare historical sea level observations collected during Sir Douglas Mawson’s 1911–1914 Australasian Antarctic Expedition (AAE), together with modern sea level data, space geodetic estimates of crustal displacement and modelling of coseismic and post-seismic earthquake deformation, we present a contemporary analysis to constrain sea level and land level change over the twentieth century at Macquarie Island (54 ◦ 30 � S, 158 ◦ 57 � E). We combine 9 months of 1912–1913 sea level data with intermediate observations in 1969–1971, 1982 and 1998–2007 to estimate sea level rise relative to the land at +4.8 ± 0.6 mm yr −1 . Combined with estimates of global mean sea level rise, this value supports the geologically surprising notion of land subsidence, conflicting with longer term geological evidence that suggests uplift at ∼0.8 mm yr −1 over the last 400–300 Kyr. We investigate the current tectonic evolution of the Island through analysis of Global Positioning System (GPS) solutions that utilize data over the period 2000–2009. Importantly, this provides an opportunity to refine the source parameters of the M w ∼8.0 great earthquake of 2004 December 23 using estimates of coseismic displacements at regional GPS sites. We use the estimated earthquake source and GPS observations of four years of post-seismic deformation at Macquarie Island to infer the rheology of the oceanic upper mantle. We find that an asthenosphere bounded by stronger material above and below is required to produce the observed post-seismic deformation, particularly in the vertical component. Assuming a Maxwell rheology, the best fit is given by an asthenospheric viscosity of 3×10 19 Pa s. The inferred rheology determined from the 2004 earthquake is used to model long period post-seismic deformation from M w ∼8.0 earthquakes of 1989 and 1924. The 1924 earthquake is the closest of the three great earthquakes to Macquarie Island, and our modelling suggests that the majority of the vertical deformation at the tide gauge over the subsequent 80 years is related to ongoing viscoelastic relaxation from this thrust earthquake that ruptured south from an epicentre south of Macquarie Island. Assimilated time-series of land level change from the earthquake modelling (suggesting ongoing subsidence) constrained by the GPS estimate of vertical velocity of −2.46 ± 0.64 mm yr −1 combine with the relative sea level time-series to yield an estimate of absolute sea level change of +2.0 ± 0.8 mm yr −1 over the twentieth century. We conclude this is consistent with the upper bound of the global average rate of absolute sea level rise over the same period. This represents one of few estimates of observed sea level change in the Southern Ocean, re-emphasizing the importance of historical data and continued geodetic and oceanographic observation in remote areas.
