Effects of biological and chemical additives on fermentation progress in maize silage

Tyrolová Y. , Bartoň L. , Loučka R. (2017): Effects of biological and chemical additives on fermentation progress in maize silage. Czech J. Anim. Sci., 62, 306–312. The objective of this study was to evaluate the effects of bacterial and chemical additives on the number of lactic acid bacteria (LAB) and on fermentation indicators in whole maize silage at 1, 3, 5, 10, and 90 days of fermentation. Maize forage was harvested at approximately 34% dry matter (DM) and treated with (1) no additive (control; C); (2) bacterial inoculant (2 g/t of forage; B) containing the homofermentative LAB Lactobacillus plantarum, Lactobacillus paracasei, and Pediococcus pentosaceus (1.5 × 1011 cfu/g of inoculant); and (3) chemical additive (4 l/t of forage; CH) containing formic acid, propionic acid, ammonium formate, and benzoic acid. Both treatments decreased pH of silage at day 1 of ensiling (P < 0.05), and the lowest value of 4.34 was observed in the CH-treated silage. All silages were well fermented and had pH < 4.0 by day 10 of fermentation. The concentration of lactic acid and the lactic acid : acetic acid ratio increased over time in all treatment groups, and the highest values were 87.5 and 3.62 g/kg of DM, respectively, observed for group B at day 90 (P < 0.05). The concentrations of water-soluble carbohydrates were higher (P < 0.05) for CH compared to C and B at days 3, 5, 10, and 90 of fermentation. The CH silage had fewer LAB (P < 0.05) than did either C or B silages regardless of the days of fermentation. Both additives used in the present study improved fermentation dynamics of the whole crop maize silage.
Experimental Observations On The Geometry And Stability Of A Laminar Diffusion Flame In Micro-gravity

An experimental study is conducted on a laminar diffusion flame established over a 50 mm x 50 mm x 10 mm slab of PMMA subject to a forced oxidizer flow parallel to the surface. The parameters varied are the oxygen concentration, the forced flow velociry and the length of pyrolyzing fuel. Experiments are conducted in micro-gravity to simulate the conditions on board spacecraft and to better approximate the assumptions of classical theoretical developments. The experimental results showed a low oxidizer velocity stability limit linked to a minimum fuel supply to the flame and related to a decrease in the heat feedback from the flame to the fuel surface. The importance of convective transfer of fuel to the flame is underlined and is evidenced by soot glowing (yellow flames) as opposed to blue flames where diffusion of fuel IS dominant. Soot particles are convected towards the flame. A qualitative correspondence of blue flames with theory is observed and significant discrepancies are evidenced as the in~portance of convection increases and the flames become yellow.
Strengths-Based Supervision: Supporting Implementation of Family-Centered Practice through Supervisory Processes

Issue Strengths-based supervision is a model that integrates supervisory processes designed to intentionally support a worker’s implementation of Family-Centered Practice (FCP). Supervisors in the child welfare system serve dual purposes of monitoring the quality of practice to ensure workers adhere to agency policies and practice guidelines. Supervisors are also mentors, who provide professional development to help workers apply their learning in the training sessions to their work in practice. Strengths-based supervision has been adopted by three states since its inception in 2008 and the elements of the model were incorporated into the training modules of the child welfare agencies’ curricula.
Elastic moduli of carbon nanotubes with new geometry based on FEM

In this paper, the elastic moduli of elliptic single walled carbon nanotubes (ESWCNTs) are described. A three-dimensional finite element (FE) model for such carbon nanotubes is proposed. The covalent bonds are simulated by beam elements in the FE model. The elastic moduli of beam elements are ascertained from a linkage between molecular and continuum mechanics. The deformations of the FE model are subsequently used to predict the elastic moduli of ESWCNTs. In order to demonstrate the FE performance, the influence of length, chirality, diameter and cross sectional aspect ratios on the elastic moduli (Young's modulus and shear modulus) of ESWCNTs is investigated. It is found that the cross sectional aspect ratio of ESWCNTs significantly affects the elastic moduli. With increasing cross sectional aspect ratio, the Young's modulus and shear modulus decrease. As a result, every change in geometry operates as a defect and decreases the elastic moduli. With increasing the length, Young's modulus increases and the shear modulus decreases.

Whatever happened to 'reflective practice'?

Donald Schon’s (1983, p. 1987) seminal work exploring the practice of professionals introduced the notion of reflective practice to describe and discuss professional artistry. Since then, literature and practices in the area have grown such that reflective practice has now become “relied” on (Clegg et al., 2002, p. 131) as a “promised land”(Papastephanou & Angeli, 2007). Code (1993, p. 27) compares rhetoric, in this case the claims made about reflective practice, to statements on a ‘display screen’ that become familiar and taken-for-granted. In this chapter, I will be identifying and questioning the assumptions contained in this familiar and taken-for-granted rhetoric, setting it alongside the complexities of professional practice, leading to the suggestion we haven’t seen ‘reflective practice’ around for some time, whatever happened to reflective practice…? The chapter will conclude with suggestions for ways forward taken from a larger piece of work, my current doctoral research.
PROYECTO FIN DE CARRERA Software quality studies using analytical metric analysis

Today engineering companies expend a large amount of resources on the detection and correction of the bugs (defects) in their software. These bugs are usually due to errors and mistakes made by programmers while writing the code or writing the specifications. No tool is able to detect all of these bugs. Some of these bugs remain undetected despite testing of the code. For these reasons, many researchers have tried to find indicators in the software’s source codes that can be used to predict the presence of bugs. Every bug in the source code is a potentially failure of the program to perform as expected. Therefore, programs are tested with many different cases in an attempt to cover all the possible paths through the program to detect all of these bugs. Early prediction of bugs informs the programmers about the location of the bugs in the code. Thus, programmers can more carefully test the more error prone files, and thus save a lot of time by not testing error free files. This thesis project created a tool that is able to predict error prone source code written in C++. In order to achieve this, we have utilized one predictor which has been extremely well studied: software metrics. Many studies have demonstrated that there is a relationship between software metrics and the presence of bugs. In this project a Neuro-Fuzzy hybrid model based on Fuzzy c-means and Radial Basis Neural Network has been used. The efficiency of the model has been tested in a software project at Ericsson. Testing of this model proved that the program does not achieve high accuracy due to the lack of independent samples in the data set. However, experiments did show that classification models provide better predictions than regression models. The thesis concluded by suggesting future work that could improve the performance of this program.
Strengthening RC beam-column connections with FRP strips

Reinforced concrete connections, designed prior to the implementation of earthquake design standards, may be vulnerable to shear failure during a seismic attack. Addition of externally bonded fibre-reinforced polymer (FRP) composites can enhance not just the shear capacity but the deformation and energy absorption capacity of the connection. The majority of research studies to date have opted for complete or near-complete coverage of the joint region with FRP and have subjected the test specimens to cyclic (push–pull) loading. Such strengthening schemes and method of loading make it quite difficult to accurately monitor and hence understand the behaviour of the FRP and the concrete beneath. This paper presents results of a series of tests on the strengthening of shear deficient connections with FRP strips subjected to either cyclic or monotonic loading with the primary motivation being accurate description of the behaviour of the FRP. The tests also enable the failure modes to be more accurately reported .
Rollover of Apparent Wave Attenuation in Ice Covered Seas

Wave attenuation from two field experiments in the ice-covered Southern Ocean is examined. Instead of monotonically increasing with shorter waves, the measured apparent attenuation rate peaks at an intermediate wave period. This ‘rollover' phenomenon has been postulated as the result of wind input and nonlinear energy transfer between wave frequencies. Using WAVEWATCH III®, we first validate the model results with available buoy data, then use the model data to analyze the apparent wave attenuation. With the choice of source parameterizations used in this study, it is shown that rollover of the apparent attenuation exists when wind input and nonlinear transfer are present, independent of the different wave attenuation models used. The period of rollover increases with increasing distance between buoys. Furthermore, the apparent attenuation for shorter waves drops with increasing separation between buoys or increasing wind input. These phenomena are direct consequences of the wind input and nonlinear energy transfer, which offset the damping caused by the intervening ice.
THE EFFECTIVENESS OF COLLOID MODULE BASED ON GUIDED INQUIRY APPROACH TO INCREASE STUDENTS' COGNITIVE LEARNING OUTCOMES

Colloid is one of the chemical topics taught in high school. Actually, the characteristic of Colloid topic is contextual. Colloid topic is taught by expository and discussion methods. Based on observations in SMA Negeri 4 Malang and SMA Negeri 16 Surabaya, these methods could not improve students’ ability to construct their own knowledge; as a result, students did not have a good understanding in the Colloid topic. An alternative way to increase students’ understanding, especially in the cognitive aspect is using innovative teaching materials like a colloid module based on guided inquiry approach. The previously mentioned module was developed by the author. The feasibility percentage of the Module was 85.66%. The aim of this research is to find the effectiveness of the Colloid Module to increase students’ cognitive learning outcomes. This research used one group pretest-posttest experimental design. The sample of this research consisted of 33 students of X-MIPA 3 SMA Negeri 2 Malang in the 2015/2016 academic year. The effectiveness of The Colloid Module to increase cognitive learning outcomes was determined by the results of paired sample t -test analysis and the gain score of students’ pretest and posttest using cognitive test instrument. This cognitive test instrument had content validity index of 92.04%. Based on the trial result of 36 students in SMA Negeri 3 Malang, 30 questions were considered valid and had a reliability coefficient of 0.866 based on Spearman-Brown. The result of this research showed that the Colloid Module was effective to increase students’ cognitive learning outcomes. It was indicated by the analysis of paired sample t -test, with t score (-38.525) lower than t critical (-2.037), so there was a significant difference between pretest and posttest scores after using the Colloid Module. The effectiveness of the Colloid Module was also determined by the gain score of pretest and posttest scores of students’ cognitive skills of 0.688, categorized as a medium gain.
Higher education students’ experiences of digital learning and (dis)empowerment

This paper focuses on learning practices in higher education in relation to a digital participatory culture. Using key principles of critical education, the research set out to explore higher education students’ sense of agency online – or lack of it –as part of their formal learning practices. The research found that although students were proficient Web users, they did not exercise their learner agency beyond what they assumed to be expected of them, thus evidencing the stability of their learning habitus in relation to the learning conventions associated with the academic field. Perhaps more surprisingly, however, is students’ perception of the Web not only as a space of student participation, but also as a space of student surveillance. Such perceptions constitute real obstacles to meaningful participation as a form learning.
Strategic Performance Measurement System and Organisation Capabilities: Using Levers of Control Framework

The purpose of this paper is to use the levers of control to examine the relationship between strategic performance measurement system and organisational capabilities. The main objective is to examine how strategic performance measurement system influences organisational capabilities. This study proposes that strategic performance measurement system is positively related to organisational capabilities. This paper reports the results of a pilot study of a mail survey. The response came from the top management of 80 Malaysian manufacturing and service firms. The results indicate that beliefs, boundary, diagnostic and interactive control system is positively and significantly correlated with overall organisational capabilities. As for the relationship of levers of control dimension and individual organisational capabilities, the result indicates an overall positive and significant relationship. However, the relationship between diagnostic use and entrepreneurship is not significant.

New insights into the environmental drivers of the circumpolar
ground thermal regime

Abstract. The thermal dynamics of permafrost shape Earth surface systems and human activity in the Arctic and have implications to global climate. Improved understanding of the fine-scale variability in the circumpolar ground thermal regime is required to account for its sensitivity to changing climatic and geoecological conditions. Here, we statistically related circumpolar observations of mean annual ground temperature (MAGT) and active-layer thickness (ALT) to high-resolution (~1 km2) geospatial data to identify their key environmental drivers. The multivariate models fitted well to MAGT and ALT observations with average R2 values being ~0.94 and 0.78, respectively. Corresponding predictive performances in terms of root mean square error were ~1.31 °C and 87 cm. Freezing air temperatures were the main driver of MAGT in permafrost conditions while thawing temperatures dominated when permafrost was not present. ALT was most strongly related to solar radiation and precipitation with an important influence from soil properties. Our findings suggest that in addition to climatic factors, initial ground thermal conditions and local-scale topography-soil-driven variability need to be considered in order to realistically assess the impacts of climate change on cold-climate geoecosystems.
The Effect of Metoclopramide on Prolactin Levels in Breastfeeding Mothers: A Systematic Review and Meta-Analysis

Background: Exclusive breastfeeding is beneficial to not only infants, but also mothers. Since prolactin stimulates milk production, increasing its levels through dopamine antagonists, such as metoclopramide, may enhance milk production. However, the efficacy of this method should be further studied. Therefore, this systematic review sought to determine the effects of metoclopramide on prolactin levels in breastfeeding mothers. Â Â Materials and Methods: Â In this systematic review study, International and National data bases such as PubMed,Google Scholar, Cochrane Library, Scopus, Web of Sciences, SID,Magiran, and Iranmedexwere searched for the keywords of lactation, breastfeeding, prolactin, metoclopramide and breast milk. Articles published during 1979 to 2016 in either English or Persian was selected. The review was limited to human clinical trials examining the effects of metoclopramide on mothersâ�� serum prolactin levels. Two authors independently evaluated the eligibility the studies and cases of disagreement were resolved through consensus. Results: Five studies on the effects of metoclopramide on mothersâ�� serum prolactin levels were included in this systematic review. Based on their results, compared to placebo, two weeks of metoclopramide administration did not have significant effects on mothersâ�� serum prolactin levels (mean difference: 73.06; 95 confidence interval CI:-19.99 to 166.11) However, placebo-controlled studies showed significant changes in prolactin levels after using metoclopramide for three weeks (mean difference: 111.06; 95% CI: 1.93 to 220.20). Â Â Â Â Â Â Â Â Conclusion: The result of meta-analysis showed that the use of 10 mg of metoclopramide three times a day for three weeks increased mothersâ�� serum prolactin levels after childbirth.

HYGIENIC SANITARY ESTIMATION OF MAIZE SILAGE IN DAIRY FARMS IN LITHUANIA

The aim of this study was to estimate maize silage hygienic sanitary parameters, contamination with mycotoxins in dairy farms in Lithuania. In 2011–2012 maize silage samples were collected from 20 dairy farms: prior to ensiling and 3 and 8 months after ensiling. In maize samples, prior to ensiling, L. monocytogenes was detected 25.0 % and after 3 months of ensiling – 10 %. Average of yeast and filamentous fungi in raw material samples were respectively – 71.39 ± 32.17 and 47.67 ± 18.31 CFU/g, after 3 months – 50.06 ± 16.09 CFU/g and 28.27 ± 13.18, after 8 months – 213.81 ± 55.98 and 215.08 ± 56.16 CFU/g. In raw maize dominated Fusarium spp. and in silage – Aspergillus, Penicillium spp. Average of lactic acid bacteria – 189.01 ± 57.79 (3 months after ensilage) and 436.11 ± 93.97 CFU/g (8 months after ensilage). Compared prior to ensilage and 3 and 8 months after ensilage maize samples, higher mycotoxins concentrations of DON – 36.96 % (P 0.05) in samples after 3 months of ensiling. Dry matter and pH respectively: prior to ensiling – 36.96 % and 5.26, 3 months after ensiling – 33.17 % and 3.84, 8 months after ensiling – 40.52 % and 3.91. The current results indicate the presence of yeast, viable fungi spores and mycotoxins AFL (total), ZEA, DON, T-2 and OTA contamination in maize silage in Lithuania. Keywords: fungi, maize silage, mycotoxin, yeast. Article DOI: http://doi.org/10.15544/RD.2015. 023
Analysis of genetic relationships of mulberry ( Morus L.) germplasm using sequence-related amplified polymorphism (SRAP) markers

Sequence-related amplified polymorphism (SRAP) is a novel molecular marker technique designed to amplify open reading frames (ORFs). Here, for the first time, SRAP was used to identify mulberry germplasm. Twenty-three mulberry accessions were screened using SRAP techniques, with 12 primer combinations selected for their reproducibility and polymorphism. Out of 83 PCR fragments scored, 59 (71.1%) were polymorphic, with an average of 4.9 polymorphic bands and 6.9 bands per primer combination. Mean gene diversity and PIC were 0.1611 and 0.1353, respectively. The genetic similarity coefficient ranged from 0.6905 to 0.9524, with an average of 0.8330. The phylogenetic tree was obtained using the UPGMA method using the total number of amplified SRAP fragments. The results from cluster analysis were in general agreement with our morphologic classification.
Ad Attributes and Attribution: Large-Scale Field Experiments Measure Online Customer Acquisition

Using a large-scale experiment involving 3.7 million treated subjects on Yahoo! , we measure the ability of online display advertising to cause new account sign-ups at an online business. We experiment with two dimensions of media choice: banner-shaped ads versus large rectangular ads, and Yahoo! Mail placement versus Yahoo! Run-of-Network placement. The Run-of-Network advertisements succeeded in generating a statistically significant increase in sign-ups of approximately 11% relative to the control group, but the Yahoo! Mail ads did not produce a statistically significant increase in sign-ups for this advertiser. By contrast with the results for choice of pages, we find no effect of the form factor of the ads (banner versus large rectangular) in this campaign. We note the somewhat surprising fact that even with experimental sample sizes in the millions of subjects, our estimates remain quite noisy: for example, the upper bound of the 95% confidence interval for the statistically insignificant Yahoo! Mail campaign represents a 15% increase in new customers. Most importantly, our estimates call into question click-only attribution models, as restricting attention to the number of users that clicked on an ad and converted is less than 30% of the estimated treatment effect on conversions.
