Masek T. , Ž. Mikulec, H. Valpotic, N. Antunac, N. Mikulec, Z. Stojevic, N. Filipovic, S. Pahovic: Influence of Live Yeast Culture (Saccharomyces cerevisiae ) on Milk Production and Composition, and Blood Biochemistry of Grazing Dairy Ewes during the Milking Period. Acta Vet. Brno 2008, 77: 547-554. A feeding trial was conducted to evaluate the influence of live yeast culture (Saccharomyces cerevisiae) on milk production, composition, and blood biochemistry of dairy ewes during the machine milking period. The control group (CD) was fed a concentrate mixture and hay and grazed twice daily, while the second (YS3) and third (YS6) groups were fed the same diet supplemented with 3 or 6 g of live yeast culture (Yea Sacc1026), respectively. The treated groups had significantly higher values (p < 0.05) for fat corrected milk (FCM) (1221, 1116 and 940 g/day, for YS6, YS3 and CD group, respectively) and fat-protein corrected milk (FPCM) (1204, 1103 and 931 g/day, for YS6, YS3 and CD group, respectively), while the values for milk yield, fat yield and lactose yield were higher (p < 0.05) only in the YS6 group compared to the CD group. Milk yield values were constantly higher in the YS6 group than in the control group while the values for the YS3 group were more variable during milking. Milk composition was not significantly affected by yeast supplementation with the exception of urea values which were lower (p < 0.05) in the YC6 group. Yeast administration influenced β-hydroxy-butyrate (BHB) values, which were higher (p < 0.05) in the treated groups; and non-esterified fatty acids (NEFA) values, which were higher (p < 0.05) only in the YS6 group compared to the control group. Other blood biochemistry values were not influenced by the treatments. We conclude that supplementation with live yeast culture, under the conditions of our experiment, had a significant effect on the performance and metabolism of grazing dairy ewes during the machine milking period. Based on more constant results, we could recommend the inclusion of live yeast culture (Yea Sacc 1026 ) at 6g/animal/day as appropriate for field conditions.
Dating of zircon and monazite from diamondiferous quartzofeldspathic rocks of the Saxonian Erzgebirge – hints at burial and exhumation velocities

Abstract In order to better understand the formation and evolution processes of ultrahigh pressure (UHP) felsic rocks, we determined the ages of various domains of zircon and monazite crystals from the diamondiferous quartzofeldspathic rocks of the Saxonian Erzgebirge. According to cathodoluminescence imagery and Th/U ratios, three zircon zones were distinguished. Each was dated using several spot analyses from a sensitive high-resolution ion microprobe analysing Pb, U and Th isotopes. The results were: (1) core zone - 21 analyses: Th/U ≤0.023 and 337.0±2.7 Ma (2σ, combined 206Pb/238U-207Pb/235U age); (2) diamond-bearing intermediate zone - 23 analyses: Th/U ≥0.037 and 336.8±2.8 Ma; and (3) rim zone -12 analyses: Th/U = 0.015-0.038 (plus one analysis of 0.164) and 330.2±5.8 Ma. The U-Pb obtained ages are virtually concordant. Furthermore, two oscillatory zoned zircon cores (Th/U ≥0.8) yielded (~concordant) ages of ~400 Ma. Six SHRIMP analyses of monazites gave an age of 332.4±2.1 Ma. In addition, Pb, Th and U contents in monazite were analysed with an electron microprobe (EMP). A mean age of 324.7±8.0 (2σ) Ma was acquired from 113 analyses. By combining the defined ages with previously published P-T conditions, minimum velocities for burial and exhumation were estimated. In addition, we present a likely geodynamic scenario involving age data from the literature as well as this study: beginning 340 million years ago, gneisses at the base of a thickened continentalcrust (~1.8 GPa, 650ºC) were transported to depths of at least 130 km, possibly as deep as 250 km. Here they were heated (>1050ºC) and partially melted and as a result began to rise rapidly. The burial and subsequent ascent back to a depth of 50 km, where zircon rims and monazite formed, took only a few million years and perhaps significantly less.
SPH simulations of clumps formation by dissipative collision of molecular clouds - I. Non magnetic case

We performed computer simulations of interstellar cloud-cloud collisions using the three-dimensional smoothed particle magnetohydrodynamics method. In order to study the role of the magnetic eld on the pro- cess of collision-triggered fragmentation, we focused our attention on head-on supersonic collisions between two identical spherical molecular-clouds. Two extreme congurations of the magnetic eld were adopted: parallel and perpendicular to the initial clouds motion. The initial magnetic eld strength was approximately 12.0 G. In the parallel case, much more of the collision debris were retained in the shocking region than in the non-magnetic case where gas escaped freely throughout the symmetry plane. Dierently from the non-magnetic case, eddy-like vortices were formed. The regions of highest vorticity and the the regions of highest density are oset. We found clumps formation only in the parallel case, however, they were larger, hotter and less dense than in the analogous non-magnetic case. In the perpendicular case, the compressed eld works as a magnetic wall, preventing a stronger compression of the colliding clouds. This last eect inhibits direct contact of the two clouds. In both cases, we found that the eld lines show a chaotic aspect in large scales. Also, the eld magnitude is considerably amplied in the shock layer. However, the eld distribution is almost coherent in the higher density regions.
Conditions that contributing the utilization and implementation of educational innovations at higher education: a review of the literature

Nowadays, use of ICT in higher education is one of the main consideration in educational improvements. Integrating ICT into the training procedures is extensively apparent as a critical assert in educational reforms. In spite of remarkable improvement higher education in many countries, integration of ICT into universities to be astonishingly low. The purpose of current paper is based on a review of 68 refereed article and dissertation that focused on introducing Ely's (1990) eight conditions that simplify implementation of an invention. Also identify which conditions more affected on successful implementation an innovation in higher education. The results shown that although there were important efforts and positive approaches toward the use of ICT in higher education, but the procedure of ICT integration at the university challenged factors that have effect on utilization of ICT by faculty members in universities. The review finding revealed that effective implementation of an innovation in higher education was dependent on the four significant factors included availability of resources, existence of knowledge and skills, availability of time, and leadership.
SHORT COMMUNICATION In vitro and in vivo survivality of gdhA derivative Pasteurella multocida B:2

Aims: This study was carried out to determine the in vitro and in vivo survival pattern and period for the newly created gdhA derivative Pasteurella multocida B:2. Methodology and results: For the in vitro study, the gdhA derivative Pasteurella multocida B:2 was cultured in BHI and stored at 4 °C and at room temperature (27 °C). This was followed by determination of the colony-forming unit (CFU)/ mL at weekly intervals. When kept at 4 °C, the bacterial concentration (CFU/mL) showed insignificant (p> 0.05) weekly reduction until week 3. By week 4, the concentration was less than 10 2 CFU/mL. In the in vivo study, the derivative was injected intraperitoneal into a group of mice and compared with the group injected intraperitoneal with wild-type P. multocida B:2 and another control group injected with PBS. It was found that the gdhA derivative P. multocida B:2 remained intact for a period of 8 h, lost its kanamycin casette after the 8-h period but remained avirulent throughout the 96 h study period when none of the mice died. On the other hand, all mice that were exposed to the wildtype P. multocida B:2 were dead within 24 h post-injection. Conclusion, significance and impact study: The gdhA derivative P. multocida B:2 seemed to survive better when kept at 4 °C and survived in the host for at least 4 days without returning the virulency. These are important since this strain can be used as live vaccine in animals with minimal possibility of returning back to virulent strain while the live vaccine can be stored at 4 °C for at least 4 weeks.
Sources of anxiety among pre-service teachers on field placement experience

This study examined pre-service students’ perceptions of their sources of anxiety during field experience. A sample of 85 undergraduate education students participated in the study (females = 52.9%). The students completed a survey on their perceptions of sources of anxiety during teaching practice. The results suggest students experience anxiety in four domains, namely preparation and execution of lesson plans, evaluation of lessons, classroom management, and relationship with host school staff. Evaluation of lessons ranked high as a source of anxiety for student teachers on field placement, followed by preparation, classroom control and relationship with the host school staff, respectively. Seeming inconsistencies between university and school-based supervisors in lesson plan formats compounded the pre-service teachers field placement-related anxieties Appropriately targeted student support interventions can help allay the fears and anxiety of pre-service teachers during teaching practice.
DYNAMIC RESPONSE AND MICROSTRUCTURE EVOLUTION OF OXYGEN-FREE HIGH-CONDUCTIVITY COPPER LINER IN EXPLOSIVELY FORMED PROJECTILE

THE DYNAMIC RESPONSE AND MICROSTRUCTURE EVOLUTION OF OXYGEN-FREE HIGH-CONDUCTIVITY COPPER IN A SHAPED CHARGE LINER OF AN EXPLOSIVELY FORMED PROJECTILE ARE INVESTIGATED THROUGH MICROSTRUCTURAL EXAMINATION OF A SOFT-RECOVERED EFP. THEORETICAL CALCULATION RESULTS INDICATE THAT THE HIGHEST TEMPERATURE INCREASE OF EFP CAUSED BY SHOCK WAVE AND PLASTIC DEFORMATION CAN REACH 673K, WHICH IS 0.5TM (WHERE TM IS THE MELTING TEMPERATURE OF COPPER), AND THE FORMATION PROCESS OF COPPER EFP IS PRIMARILY CAUSED BY EXTREME PLASTIC FLOW, WHICH IS POSSIBLY A TYPE OF SUPERPLASTIC FLOW IN A SOLID STATE. THE MAIN BODY OF THE EFP UNDERGOES COMPLETELY DYNAMIC RECRYSTALLISATION, AND THE AVERAGE SIZE OF THE REFINED GRAINS SIGNIFICANTLY DECREASES TO APPROXIMATELY 10ΜM. A SLIGHT INCREASE IN GRAIN SIZE OCCURS MAINLY AWAY FROM THE CENTER AND EXTENDS TOWARDS THE HEAD AND REAR SECTIONS OF THE EFP. DURING THE DRX PROCESS, THE DISLOCATION MOVEMENTS ARE BELIEVED TO BE THE CONTROLLING MECHANISMS SIGNIFICANTLY REFINING THE MICROSTRUCTURE AND HELPING IN THE FURTHER FLOW OF THE MATERIAL.
Factors controlling micropropagation of Myrica esculenta buch. – Ham. ex D. Don: a high value wild edible of Kumaun Himalaya

Various factors such as browning, season, media type and plant growth regulators influence the micropropagation of female trees of Myrica esculenta . These factors have successfully been addressed after addition of some media additives, collection of the explant at right season, standardizing the media type and use of plant growth regulators at varying concentrations. Polyvinylpyrollidone (PVP - 0.5%) was found effective for successful partial removal of phenolic compounds and obtaining maximum percent survival of explants. The explant collection season played an important role in reducing phenol induced browning and winter season was found best for explant establishment. The maximum number of shoots (4-5/explant) was obtained in Woody Plant Medium (WPM) supplemented with 10µM kinetin and 0. 1µM naphthalene acetic acid (NAA). Of all the media types tried, Woody Plant Medium was found to be the best. Kinetin was found superior to benzyl amino purine and N 6 (γ,γ-dimethylallyamino)purine (2iP) for explant establishment and multiplication. NAA induced rooting to 45.8% of explants in 1/2 strength Woody Plant Medium. However, ex vitro survival percentage was low.

Endogenous attention and lateral interference

Lateral interference refers to the phenomenon that a target that is surrounded by other stimuli with a small interstimulus distance is more difficult to identify than a target that is surrounded by stimuli with a large interstimulus distance. In a few studies it was argued that the effect of lateral interference can be reduced when exogenously cued attention is already focused at the target-location which was ascribed to an effect of attention on early perceptual stages of stimulus-processing. However, the measures for lateral interference that were used in these earlier studies were all somewhat susceptible to influences from later stages of stimulus processing. To obtain more conclusive results with regards to the stage at which attention can modulate stimulus processing, measures derived from signal detection theory were used in the present study. Attention was manipulated by endogenous cues to prevent forward masking. As stimuli, circular arrays with a target at their center were used, interstimulus distance was varied between two values, and the endogenous cue was valid in 75% of the cases whereas it was invalid in 25% of the cases. No evidence for a reduction of lateral interference was found, what can be explained by differing efficiency of endogenous and exogenous cues at an early, perceptual stage of stimulus-processing.

A FRAP Assay at pH 7 unveils Extra Antioxidant Activity from Green, Black, White and Rooibos Tea but not Apple Tea

Aim: Realization of a ferric reducing antioxidant power (FRAP) assay at neutral pH and re-evaluation of tea antioxidant activity for comparisons with the standard FRAP assay.Method: A FRAP assay at neutral pH utilized ferrozine (7.3- (2-Pyridyl)-5, 6-diphenyl-1, 2, 4-triazine-4’, 4’’-disulfonic acid; ferrozine) dye in conjunction with Tris-HCl buffer (0.1M. pH7.0) with 280 µl of regent addition to 20 µl of tea infusions and absorbance measurements at 562 nm with a microplate reader.Results: The microplate ferrozine FRAP assay (mFzFRAP) gave linear calibrations for ascorbic acid, gallic acid, ammonium ferrous sulphate, (AFS), trolox, cysteine and glutathione (R2 =0.998 -1.000) with molar absorptivity (measures of sensitivity) similar to literature values. The analytical precision was 5-7% and the minimum detectable concentrations (MDC) were 1.4-2.8 µM (0.4-0.8 nanomoles). Discussion: Values for FRAP were higher at pH 7.0 compared to pH 4.0 for gallic acid, ascorbic acid, glutathione, and cysteine possibly due to their ionization at high pH. The assay sensitivityfor AFS and trolox were unchanged at pH 4.0 and pH 7.0. When assayed at pH 7 the water infusions from green tea, black tea, white tea, and rooibos tea had 200-360% antioxidant activitynormally observable at low pH.Conclusion: A FRAP assay at pH 7 unveils extra antioxidant activity for green, black, white and Rooibos teas compared to values from the standard TptzFRAP (pH 3.6) method. As arecommendation, the antioxidant activity of teas and other herbal preparations should be re-evaluated over a wide pH range.
Study of the Jet-Induced Mixing of Two-Layer Density-Stratified Fluid in a Rectangular Tank

The mixing phenomena of a two-layer density-stratified fluid induced by a jet in a tank are experimentally investigated. The upper and lower fluids are water and a NaCl-water solution, respectively, with the lower fluid issued vertically upward from a nozzle at the bottom of the tank. The jet Reynolds number Re, defined by the jet velocity and the water kinematic viscosity, ranges from 90 to 4,200. The mass concentration of the NaCl-water solution C0 is less than 0.08. The flow visualization makes clear the jet behavior relative to the density interface between the upper and lower fluids. The measurement of the concentration distribution of the water paint issued with the jet highlights the effects of Re and C0 on the mixing between the jet and the ambient fluid. The measurement of the fluid velocity distribution with a PIV (particle image velocimetry) system successfully elucidates the relationship between the velocity field and the resultant mixing.
Music Makes You Smarter: A New Paradigm for Music Education? Perceptions and Perspectives from Four Groups of Elementary Education Stakeholders.

Through 14 years of teaching music in the Greater Toronto Area, the “music makes you smarter” notion has imbued many of the conversations I have had with multiple stakeholders in public education. Such conversations have suggested that the ancillary benefits of teaching music have now become the principal reason why we teach music -- what I refer to as a new paradigm shift in music education. This study attempts to validate my own experiences through a sample size of 100 participants and a multiple methods approach to inquiry. Specifically, this study explores the perceptions and perspectives of the “music makes you smarter” notion by four groups of stakeholders in elementary education, namely; music teachers, students, parents, and non-music teachers. With a few exceptions, both quantitative and qualitative data have generated perceptions and perspectives that validate the “music makes you smarter” notion, suggesting that my own experiences of a paradigm shift within music education in the GTA were indeed authentic and valid. This paper ends with a discussion on the ramifications of this new paradigm shift and ultimately argues that the music itself should be the focus of music education. Key words: Music Education, Paradigm Shift, Perceptions, Perspectives, & Mixed Methods
Linking SMEs Profitability to Brand Orientation and Market-Sensing Capability: A Service Sector Evidence

The key question among policy makers and marketing scholars alike is 'how can SMEs become more financially viable? ' bearing in mind that we now live in a highly globalized society that is driven by technological, social and economic forces. Consequently, for SMEs to become more financially viable in the changing business landscape, it becomes more imperative now than ever before for this set of enterprises to develop some core business orientations and/or capabilities, particularly that of brand orientation and market-sensing capability. Against this backdrop, the current article examines the role of brand orientation and market-sensing capability in relation to the profitability of SMEs in the context of a financial intermediation sector. Based on the findings from 119 surveyed financial services SMEs in one of Africa’s largest economies, we have empirical support that both brand orientation and market-sensing capability contribute significantly to SMEs profitability. Our results demonstrate the need for SMEs in the African financial intermediation sector to develop an 'in-house' branding culture that takes into cognizance 'local' market conditions, and more particularly employee involvement. More so, SMEs should endeavour to develop market-sensing capability given that this unique capability is key to unlocking both present and future marketing opportunities.
The Socioeconomic Determinants of Mental Stress in Ireland

This paper reviews Irish evidence on the link between socioeconomic factors and various measures of mental stress and well-being. The paper reviews both cross-section and time-series studies and finds that of all socioeconomic determinants, the most consistent role is found for unemployment. In general, stronger results are found for males than for females, but the time series evidence suggests that the relationship between suicide and unemployment appears to be weakening.
POTENTIAL USE OF PHOSPHATE WASTES AS AGGREGATES IN ROAD CONSTRUCTION

Large quantities of solid wastes are generated in El-Nassar Mining Company at Sebaeya, Egypt as a result of mineral processing of phosphate ores. Over the years, the majority of these wastes have been stored in dumping areas which is aesthetically unattractive and degrading to the environment. However, these wastes, because of their similarity to conventional soils and aggregates, represent potentially useful sources of material for a variety of applications. This paper is concerned with investigating the suitability of the coarse solid wastes generated from upgrading sebaeya phosphate ores as aggregates for road paving. The properties of these wastes are tested, according to the Egyptian Standard Test Methods for road constructions. The obtained results proved that this kind of wastes can be used in road construction. The positive uses of these wastes are considered beneficial from the economic and environmental point of view.
