Rapid productization seeks to add value to a company in sales negotiation.
Semipurified glycerins on starting piglets feeding (15-30 kg) - doi: 10.4025/actascianimsci.v35i2.17264

The nutritional value and the performance of piglets fed on diets with semipurified glycerin (SPGV) and mixed (SPGM) vegetable oil was determined and evaluated. Thirty-two crossbred piglets, allotted in a completely randomized block design, were used in the digestibility trial. Two types of glycerin (SPGV and SPGM) and three levels of diet (4, 8 and 12%) were studied. The experimental unit consisted of one piglet. Glycerins’ metabolizable energy (ME) was estimated by regression of ME (kcal kg -1 ) intake associated with glycerin vs . glycerin intake (kg). ME as-feed-basis rates were 3,373 for SPGV and 2,932 for SPGM, or rather, the glycerins are highly available energy source for piglets. In the performance trial, 90 piglets were allotted in a completely randomized blocks design in a 2 x 4 + 1 factorial scheme, two glycerins, four levels (3, 6, 9 and 12%), five replicates (pens) and two piglets per pen. A control diet with no glycerin (0%) was additionally formulated. Since no effect of glycerin inclusion on pig performance occurred, it was feasible to use up to 12% of both types of glycerin on piglets feeding.
A spatial evaluation of high-resolution wind fields from empirical and dynamical modeling in hilly and mountainous terrain

Abstract. Empirical high-resolution surface wind fields, automatically generated by a weather diagnostic application, the WegenerNet Wind Product Generator (WPG), were intercompared with wind field analysis data from the Integrated Nowcasting through Comprehensive Analysis (INCA) system and with regional climate model wind field data from the Consortium for Small Scale Modeling Model in Climate Mode (CCLM). The INCA analysis fields are available at a horizontal grid spacing of 1 km × 1 km, whereas the CCLM fields are from simulations at a 3 km × 3 km grid. The WPG, developed by Schlager et al. (2017, 2018), generates diagnostic fields on a high-resolution grid of 100 m × 100 m, using observations from two dense meteorological station networks: the WegenerNet Feldbach Region (FBR), located in a region predominated by a hilly terrain, and its Alpine sister network, the WegenerNet Johnsbachtal (JBT), located in a mountainous region. The wind fields of these different empirical–dynamical modeling approaches were intercompared for thermally induced and strong wind events, using hourly temporal resolutions as supplied by the WPG, with the focus on evaluating spatial differences and displacements between the different datasets. For this comparison, a novel neighborhood-based spatial wind verification methodology based on fractions skill scores (FSSs) is used to estimate the modeling performances. All comparisons show an increasing FSS with increasing neighborhood size. In general, the spatial verification indicates a better statistical agreement for the hilly WegenerNet FBR than for the mountainous WegenerNet JBT. The results for the WegenerNet FBR show a better agreement between INCA and WegenerNet than between CCLM and WegenerNet wind fields, especially for large scales (neighborhoods). In particular, CCLM clearly underperforms in the case of thermally induced wind events. For the JBT region, all spatial comparisons indicate little overlap at small neighborhood sizes, and in general large biases of wind vectors occur between the regional climate model (CCLM) and analysis (INCA) fields and the diagnostic (WegenerNet) reference dataset. Furthermore, grid-point-based error measures were calculated for the same evaluation cases. The statistical agreement, estimated for the vector-mean wind speed and wind directions again show better agreement for the WegenerNet FBR than for the WegenerNet JBT region. A combined examination of all spatial and grid-point-based error measures shows that CCLM with its limited horizontal resolution of 3 km × 3 km, and hence too smoothed an orography, is not able to represent small-scale wind patterns. The results for the JBT region indicate significant biases in the INCA analysis fields, especially for strong wind speed events. Regarding the WegenerNet diagnostic wind fields, the statistics show acceptable performance in the FBR and somewhat overestimated wind speeds for strong wind speed events in the Enns valley of the JBT region.
Evaluation of growth, yield and nutrient content with microbial consortia combined with different organic manures in Rumex acetosella L.

The present study was carried out to evaluate the response of microbial bioinoculants along with different organic manures (vermicompost and greencompost) on growth, yield and nutrient uptake of Rumex. Field experiments were carried out in 2010-2011 in randomized replicated block designs consisting of four replicates of each treatment. The experiment consisted of five different microbial bioinoculants combined with two organic manures. Various treatments given to Rumex were Frateuria aurentia (potassium mobilizer) Trichoderma viride (biocontrol agent), Azospirillium brasilense (Nitrogen source) and Pseudomonas fluorescens (plant growth promoting bacteria) significantly increased plant biomass, yield and nutrient content of Rumex. Results revealed that among the two organic manures vermi compost combined with bioinoculants significantly influenced the growth and nutrient uptake. Plants inoculated with vermicompost and Frateuria
The highly luminous Type Ibn supernova ASASSN-14ms

We present photometric and spectroscopic follow-up observations of the highly luminous Type Ibn supernova ASASSN-14ms, which was discovered on UT 2014-12-26.61 at mV ∼ 16.5. With a peak absolute V-band magnitude brighter than −20.5, a peak bolometric luminosity of 1.7 × 1044 erg s−1, and a total radiated energy of 2.1 × 1050 erg, ASASSN-14ms is one of the most luminous Type Ibn supernovae yet discovered. In simple models, the most likely power source for this event is a combination of the radioactive decay of 56Ni and 56Co at late times and the interaction of supernova ejecta with the progenitor's circumstellar medium at early times, although we cannot rule out the possibility of a magnetar-powered light curve. The presence of a dense circumstellar medium is indicated by the intermediate-width He I features in the spectra. The faint (mg ∼ 21.6) host galaxy SDSS J130408.52+521846.4 has an oxygen abundance below 12 + log (O/H) ≲ 8.3, a stellar mass of M* ∼ 2.6 × 108 M⊙, and a star formation rate of SFR ∼ 0.02 M⊙ yr−1.
The Determinants of Forward-Looking Information in Management Commentary: Evidence from Italian Listed Companies

The aim of this paper is to assess the level of forward-looking information in Management Commentaries of Italian listed companies and to empirically explore the firm characteristics that may affect the extent of forward-looking information disclosed. A disclosure index composition consisting of 15 forward-looking information items is developed to investigate the level of forward-looking information in Management Commentaries of a sample of companies listed on Italian Stock Exchange for the year 2010. Using content analysis the study confirms that these companies are reluctant to provide forward-looking information in Management Commentaries. Three hypotheses are proposed and six models are tested within a regression analysis in order to explore the effect of three main variables (firm size, profitability and leverage) on forward-looking information. The results show that profitability has significant association with the level of specific types of forward-looking information. Conversely, firm size and leverage are found to be insignificant in explaining the level of forward-looking information.
The mechanics of motorised momentum exchange tethers when applied to active debris removal from LEO

The concept of momentum exchange when applied to space tethers for propulsion is well established, and a considerable body of literature now exists on the on-orbit modelling, the dynamics, and also the control of a large range of tether system applications. The authors consider here a new application for the Motorised Momentum Exchange Tether by highlighting three key stages of development leading to a conceptualisation that can subsequently be developed into a technology for Active Debris Removal. The paper starts with a study of the on-orbit mechanics of a full sized motorised tether in which it is shown that a laden and therefore highly massasymmetrical tether can still be forced to spin, and certainly to librate, thereby confirming its possible usefulness for active debris removal (ADR). The second part of the paper concentrates on the modelling of the centripetal deployment of a symmetrical MMET in order to get it initialized for debris removal operations, and the third and final part of the paper provides an entry into scale modelling for low cost mission design and testing. It is shown that the motorised momentum exchange tether offers a potential solution to the removal of large pieces of orbital debris, and that dynamic methodologies can be implemented to in order to optimise the emergent design.
What Explains Collective Action in Forest Management? Evidence from Benishangul Gumuf Region, Ethiopia

This study examines factors that influence collective action in the lowland bamboo forest of Benishangul Gumuz region. The study is based on data obtained from randomly selected 384 households. Descriptive and econometric models were used to analyze the data. After controlling for heterogeneity among households, we find strong substitution opportunities across collective action initiatives. The result shows that that participation in NRM is significantly influenced by factors, such as agro-ecology, settlement condition, households’ income, networking, and households’ perceptions towards group size. Whereas sex of household head, forest property rights, and gross income earned, heterogeneity and networking are the most important factors determining participation in hazard management. Indeed, sex of the household head, property rights, and networking capacity were found to be the important determinants of participation in information provision. These findings support the need to strengthen collective action institutions to manage local bamboo forest resources. Moreover, the results suggest the need for a diagnostic approach in the analysis of collective action in diverse socioeconomic and ecological settings.
Unsteady MHD Boundary Layer Flow of an Incompressible Micropolar Fluid over a Stretching Sheet

Aim of the paper is to investigate the MHD effects on the unsteady boundary layer flow of an incompressible micropolar fluid over a stretching sheet when the sheet is stretched in its own plane. The stretching velocity is assumed to vary linearly with the distance along the sheet. Two equal and opposite forces are impulsively applied along  x axis so that the sheet is stretched, keeping the origin fixed in a micropolar fluid. The governing non-linear equations and their associated boundary conditions are first cast into dimensionless form by a local non-similarity transformation. The resulting equations are solved numerically using the Adams- Predictor Corrector method for the whole transient from the initial state to final steady- state flow. Numerical results are obtained and a representative set is diaplaced graphically to illustrate the influence of the various physical parameters on the velocity profiles, microrotation profiles as well as the Skin friction coefficient for various values of the material parameter K. It is found that there is a smooth transition from the small- time solution to the large- time solution. Results for the local skin friction coefficient are presented in table as well as in graph.
Spiral-shaped wavefronts in a sunspot umbra

Context. Solar active regions show a wide variety of oscillatory phenomena. The presence of the magnetic field leads to the appearance of several wave modes whose behavior is determined by the sunspot thermal and magnetic structure. Aims. We aim to study the relation between the umbral and penumbral waves observed at the high photosphere and the magnetic field topology of the sunspot. Methods. Observations of the sunspot in active region NOAA 12662 obtained with the GREGOR telescope (Observatorio del Teide, Tenerife, Spain) were acquired on 2017 June 17. The data set includes a temporal series in the Fe I 5435 Å line obtained with the imaging spectrograph GREGOR Fabry-Pérot Interferometer (GFPI) and a spectropolarimetric raster map acquired with the GREGOR Infrared Spectrograph (GRIS) in the 10 830 Å spectral region. The Doppler velocity deduced from the restored Fe I 5435 Å line has been determined, and the magnetic field vector of the sunspot has been inferred from spectropolarimetric inversions of the Ca I 10 839 Å and the Si I 10 827 Å lines. Results. A two-armed spiral wavefront has been identified in the evolution of the two-dimensional velocity maps from the Fe I 5435 Å line. The wavefronts initially move counterclockwise in the interior of the umbra, and develop into radially outward propagating running penumbral waves when they reach the umbra-penumbra boundary. The horizontal propagation of the wavefronts approximately follows the direction of the magnetic field, which shows changes in the magnetic twist with height and horizontal position. Conclusions. The spiral wavefronts are interpreted as the visual pattern of slow magnetoacoustic waves which propagate upward along magnetic field lines. Their apparent horizontal propagation is due to their sequential arrival to different horizontal positions at the formation height of the Fe I 5435 Å line, as given by the inclination and orientation of the magnetic field.
Price-quality schema orientation and market efficiency perceptions : a cross cultural and intercultural study of Canadians and Chinese

This study investigates 1) whether Canadians have stronger price-quality schemas (PQ) and perceptions of market efficiency (ME) than Chinese in both Canada and China, and 2) how acculturation affects Chinese immigrants’ PQ and ME. A pre-test and a main study were conducted. In the main study, data from 192 Canadians, 148 Chinese immigrants, and 170 domestic Chinese usable questionnaires were collected in Canada and China. PQ, ME, acculturation, individualism, and collectivism scales were adopted from prior studies. Data was analyzed by t-tests, ANOVA, ANCOVA, and regressions analyses. Findings showed that Canadians have significantly stronger PQ and ME than their Chinese immigrant in Canada and domestic Chinese with exception of that Chinese immigrant have an even stronger PQ than Canadians. Acculturation was not significantly related with Chinese immigrants’ PQ or ME. However, individualism and collectivism were found related to three consumer groups’ PQ and/or ME.
Genetic behavior and impact of various quantitative traits on oil contents in sunflower under waters stress conditions at productive phase.

The research pertaining to the genetic behavior and impact of various quantitative traits on oil contents in sunflower under water stress conditions at reproductive stage in ten accessions (G-5 G-3, G-9, G-33, G-57, G-93, G-128, A133, A-75 and HBRS-2) of sunflower was conducted following a triplicate randomized complete block design. The genotypes exhibited significant varietal differences among them for all the characters studied. Whorls per head (0.53) and number of leaves (0.66) displayed highest genotypic and phenotypic coefficients of variation respectively. Heritability in broad sense was the maximum for oil contents (0.715±0.346) followed by achene yield per plant (0.499±0.289) with considerable values of genetic advances indicating the involvement of some additive effects in the inheritance of these traits. Total leaf area exhibited the uppermost value of genetic advance (77.088) with moderate heritability (45±2.76). Plant height showed positive and significant genotypic association with leaf area and achene yield. Similarly number of leaves displayed positive and significant correlation (r=0.727*) with total leaf area and oil contents at genotypic level. The parameters stem diameter, head diameter, whorls per head and fertile whorls per head demonstrated positive and significant genotypic and phenotypic relationship between them. The number of whorls per head disclosed positive genetic association (r=0.625*) with oil contents while oil contents were negative associated with hundred achene weight (r= -0.768*). Path analysis based on oil content as dependent variable revealed that number of leaves, total leaf area, stem diameter and achene yield exerted positive direct effects on the oil contents being stem diameter at the top of the list. Stem diameter exposed the highest indirect positive effects on oil contents through head diameter, whorls per head and fertile whorls per head. These studies revealed that the selection of traits positively associated with oil contents and having positive direct and indirect effects on it could be an efficient selection criteria for oil contents in sunflower.
Pastoral care to or with sex-starved pregnant women in an African context

The aim of this article is to highlight some African women’s problematic sex life, even in their married lives, as a result of prescribed and lengthy periods of abstinence from sex – especially during pregnancy. Literature studies, especially on Yoruba sexual practices, showed that forced abstinence from sexual activity during pregnancy is rife and that many women seem content with the situation, probably as a result of their internalisation of patriarchal beliefs and values, prescribed as a means of socialisation. This phenomenon of abstinence from sexual intercourse during pregnancy by the women in some African societies is the focus of the study. The article examined the following: views of sex amongst Black African people, medical views of sex and views of sex in Christian tradition. Also examined at length was the phenomenon of abstinence from sex in an African context. The findings led to a critical evaluation of the phenomenon and a search for pastoral guidelines that could facilitate transformation, intimacy and committed sexual life in African families. Die doel van hierdie artikel is om die problematiese seksuele lewens van sommige vrouens in Afrika na vore te bring. Die probleme kom voor ten spyte van die feit dat hulle getroud is omdat lang tydperke van onthouding, veral tydens swangerskap, vir hulle voorgeskryf word. ’n Literatuurstudie, veral oor die Yoruba se seksuele praktyke, dui daarop dat gedwonge onthouding van seksuele aktiwiteite gedurendede swangerskap heersend is. Verder kom dit ook voor asof baie vrouens nie daarmee probleme ervaar nie, waarskynlik as gevolg van hulle geinternaliseerde patriargale oortuigings en waardes, wat vir sosialiseringsdoeleindes voorgeskryf word. Hierdie studie fokus op die verskynsel van onthouding van geslagsomgang gedurende swangerskap deur vrouens in sommige Afrika-gemeenskappe. Die artikel ondersoek die volgende: Swart Afrikane se tradisionele seksbeskouing, die mediese seksbeskouing en die Christelike tradisie se seksbeskouing. Die verskynsel van seksonthouding in ’n Afrika-konteks word ook ondersoek. Die bevindinge lei tot ’n kritiese evaluering van die fenomeen en die soeke na pastorale riglyne wat transformasie, intimiteit en toewyding in seksuele verhoudings in families in Afrika sou kon fasiliteer.
Genotype and site differences in the fatty acid composition of muscle phospholipids in cattle

Phospholipid data from the Longissimus dorsi (eye muscle) and M. brachii (shoulder muscle) of Jersey and Limousin cattle were used to study the effects of genotype, anatomical site and their interactions on fatty acid composition. Results indicated that phospholipids of the two muscles did not differ in total saturated, monounsaturated and polyunsaturated fatty acids. However, they differed in specific fatty acids 18:0 and 22:5. Genotype was a significant source of variation for the individual fatty acids 18:2 and 18-di-methyl-aldehyde (18-DMA). Significant genotype by anatomical site interactions were observed in the levels of 18-DMA, 18:0, 18:2 and 20:5 fatty acids. It was concluded that the fatty acid composition of phospholipids from biopsy samples of the L. dorsi and M. brachii muscles were similar, but there were significant differences in some individual fatty acids. Furthermore, attention should be paid to genotype by anatomical site interactions that can exist in some individual fatty acids.
INLFUENCE OF INCREASING NITROGEN FERTILIZATION ON CONTENT OF MICROELEMENTS IN GRASSES CULTIVATED ON ORNAMENTAL LAWNS

The main aim of the study, conducted in 2007-2008, was to define the influence of nitrogen levels 0, 50, 100, 150, 200 mg N dm –3 applied to grass lawns on the content of metallic microelements: iron, manganese, zinc and copper and on their quantitative ratios in turf grass. The study was carried out on a 2-year-old lawn, composed of a mixture of lawn grasses species and varieties: perennial ryegrass (Lolium perenne L.) var. Grasslands Nui (45%), tall fescue (Festuca arundinacea Schreb) Finelawn (25%), red fescue (Festuca rubra Hack.) Olivia (10%), red fescue (Festuca rubra Hack.) Boreal (15%) and Kentucky bluegrass (Poa pratensis L.) Balin (5%). With the exception of copper, the nitrogen fertilization raised the content of iron, manganese and zinc in aerial plant parts. The application of nitrogen (as ammonium nitrate) increased the uptake of nutrients by aerial plant parts: Fe to 143.0%, Mn – 227.2%, Zn – 233.3% Cu – 180.7%, and modified the ratios between amounts of the microelements. In general, it has been demonstrated that nitrogen nutrition of plants grown on ornamental lawns, within ranges of N – 150 to N – 200, increased the ratios of Fe : Mn : Zn : Cu. The best ornamental quality of lawns was obtained where the aerial plant parts contained (in mg kg–1 d.m.): Fe 231.6-292.8, Mn 35.6-50.5, Zn 26.5-47.5 and Cu 16.9-17.6. These ranges could be recommended as preliminary guidelines for ornamental lawns. In practice, considering the positive and stimulating influence of nitrogen nutrition on crops, the chemical composition of plants and the uptake of microelements by a mixture of grasses on ornamental lawns, it is crucial to monitor actual fertilization by taking into account losses of nutrients. These losses are caused by intensive uptake of nutrients by the aerial plant parts and due to the leaching of nutrients from the rhizosphere. It is necessary to replenish lost elements using mineral fertilizers.
