Effects of distillers dried grains with solubles on amino acid digestibility, growth performance, and carcass characteristics of growing pigs1

Abstract Two experiments were conducted to compare the standardized ileal digestibility (SID) of AA by growing pigs in European distillers dried grains with solubles (DDGS) produced from wheat, maize, or wheat–maize mixtures and to test the effect of increasing the inclusion levels of wheat DDGS on growth performance of growing-finishing pigs fed diets balanced for NE and SID Lys. In Exp. 1, 12 barrows (initial BW: 23.0 ± 2.2 kg) were surgically equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 6 × 6 Latin square design with six diets and six periods. Five sources of European DDGS were used: wheat DDGS from 2011, wheat DDGS from 2012, wheat-80 DDGS (80% wheat and 20% maize), wheat-70 DDGS (70% wheat and 30% maize), and maize DDGS. Each diet contained one source of DDGS as the sole source of AA and an N-free diet was used to determine basal endogenous losses of AA. Results indicated that the SID of CP was greater (P < 0.05) in maize DDGS compared with wheat DDGS from 2011, wheat DDGS from 2012, and wheat-70 DDGS. The SID of all indispensable AA except Trp was also greater (P < 0.05) in maize DDGS compared with all other DDGS sources used in this experiment. For Trp, the SID in wheat-80 DDGS, wheat DDGS from 2011, and wheat DDGS from 2012 were not different from maize DDGS, but were greater (P < 0.05) than in wheat-70 DDGS. The SID for all indispensable AA except Ile and Trp in wheat-70 DDGS were not different from the values calculated for wheat DDGS from 2011 and wheat DDGS from 2012, and no differences between SID values for AA in wheat DDGS from 2011 and wheat DDGS from 2012 were observed. In Exp. 2, 36 growing pigs (initial BW: 38.3 ± 1.97 kg) were randomly allotted to one of four dietary treatments (one pig/pen and nine replicate pigs/treatment) in a 2-phase feeding program (35 to 65, and 35 to 105 kg BW). The four dietary treatments included diets containing 0%, 10%, 20%, or 30% wheat DDGS. Results indicated that there was no effect of wheat DDGS on pig growth performance or carcass quality. However, addition of wheat DDGS increased linearly (P < 0.015) the indole concentration in the carcasses of the pigs. In conclusion, the SID of AA in maize DDGS produced in Europe is greater than in European wheat DDGS and DDGS produced from mixtures of wheat and maize, but inclusion of 30% wheat DDGS in diets fed to growing-finishing pigs did not affect growth performance or carcass quality.
On the Use of Wind Power for Transient Stability Enhancement of Power Systems

This report deals with the impact of doubly fed induction generators on the stability of a power system. The impact was quantified by means of detailed numerical simulations. The report contains a full description of the simulation, and details of the small signal analysis performed to analyse the system.Before the simulation results are presented, a foundation is laid, explaining the theory required to understand the models used and the calculations performed in the simulation.The derivation of a model of a doubly fed induction generator is presented, along with a description of the model of a synchronous generator. These are used in the simulation and analysis of a multi-machine power system, consisting of both of these types of generators.An explanation of how dynamic simulations of power systems can be performed is also put forward. This is useful, not only for understanding the simulation performed for this report, but as a guide to performing simulations of this type. This is true also for a description of linearisation and small signal analysis contained in this report.The software package MATLAB is used to perform the simulations, and the small signal analysis. Since the method described in this report is very general, it can be used to perform similar power system simulations for other power systems, and with other software.Numerical simulations reveal that the addition of doubly fed generators, such as those in wind parks, to a power system improves the response of the system after small disturbances, but can worsen it after larger disturbances.

A Low-cost Multihop Wireless Sensor Network, Enabling Real-Time Management of Environmental Data for the Greenhouse and Nursery Industry

A low-cost multi-hop wireless sensor network has been developed, deployed and are tested that enables the capture and synthesis of real-time root zone substrate and environmental data, on a wide-area basis in the field. Plant water requirements can vary by day, season and microclimate, depending on any number of environmental and plant developmental factors. Irrigation and nutrient applications can be more precisely scheduled by using the plant to integrate environmental and growth differences over time, and by accurately monitoring the real-time water use of plants with substrate moisture, temperature and electrical conductivity sensors. This should reduce water use, leaching of nutrients and overall runoff from intensive plant growing operations. Additionally, other sensors that simultaneously measure air temperature, canopy relative humidity, leaf wetness, and photosynthetically active radiation will allow us to model and better predict plant stress and disease pressure. Data can be provided at any time to anyone at any place with internet access, since all data is managed through a web-based graphic-user interface. These sensor networks are entirely portable, allowing rapid deployment of the sensors in specific areas of the facility, to optimize the utility and cost of the sensors. These networks are also scaleable, since additional nodes are easily added which allows the plant production facility to grow and/or improve their sensor network at any time.
Influence of Tool Path Strategies and Pocket Geometry on Surface Roughness in Pocket Milling

This paper discusses the effect of tool path strategies and pocket geometry to surface roughness due to pocket milling process. The machining processes have been performed on mould steel DF2 using carbide insert end mill as the cutting tool. The cutting parameters for this experiment were kept constant while the variables were cutting tool, path strategies and pocket geometries at three levels each. The effectiveness of different tool path strategy and different pocket geometry is evaluated in terms of measured surface roughness (Ra) of the workpiece. The grade of a pocket is directly proportional with its surface roughness. The lowest surface roughness measurement was produced by pocket geometry B with parallel spiral cutting tool path strategy.
ISOLOK VALVE ACCEPTANCE TESTING FOR DWPF SME SAMPLING PROCESS

Evaluation of the Defense Waste Processing Facility (DWPF) Chemical Process Cell (CPC) cycle time identified several opportunities to improve the CPC processing time. Of the opportunities, a focus area related to optimizing the equipment and efficiency of the sample turnaround time for DWPF Analytical Laboratory was identified. The Mechanical Systems & Custom Equipment Development (MS&CED) Section of the Savannah River National Laboratory (SRNL) evaluated the possibility of using an Isolok{reg_sign} sampling valve as an alternative to the Hydragard{reg_sign} valve for taking process samples. Previous viability testing was conducted with favorable results using the Isolok sampler and reported in SRNL-STI-2010-00749 (1). This task has the potential to improve operability, reduce maintenance time and decrease CPC cycle time. This report summarizes the results from acceptance testing which was requested in Task Technical Request (TTR) HLW-DWPF-TTR-2010-0036 (2) and which was conducted as outlined in Task Technical and Quality Assurance Plan (TTQAP) SRNL-RP-2011-00145 (3). The Isolok to be tested is the same model which was tested, qualified, and installed in the Sludge Receipt Adjustment Tank (SRAT) sample system. RW-0333P QA requirements apply to this task. This task was to qualify the Isolok sampler for use in the DWPF Slurry Mix Evaporator (SME) sampling process.more » The Hydragard, which is the current baseline sampling method, was used for comparison to the Isolok sampling data. The Isolok sampler is an air powered grab sampler used to 'pull' a sample volume from a process line. The operation of the sampler is shown in Figure 1. The image on the left shows the Isolok's spool extended into the process line and the image on the right shows the sampler retracted and then dispensing the liquid into the sampling container. To determine tank homogeneity, a Coliwasa sampler was used to grab samples at a high and low location within the mixing tank. Data from the two locations were compared to determine if the contents of the tank were well mixed. The Coliwasa sampler is a tube with a stopper at the bottom and is designed to obtain grab samples from specific locations within the drum contents. A position paper (4) was issued to address the prototypic flow loop issues and simulant selections. A statistically designed plan (5) was issued to address the total number of samples each sampler needed to pull, to provide the random order in which samples were pulled and to group samples for elemental analysis. The TTR required that the Isolok sampler perform as well as the Hydragard sampler during these tests to ensure the acceptability of the Isolok sampler for use in the DWPF sampling cells. Procedure No.L9. 4-5015 was used to document the sample parameters and process steps. Completed procedures are located in R&D Engineering job folder 23269. « less
Management guidelines for the implementation of m–learning in an open distance learning model

Various modern communication technologies are available to higher education institutions involved in distance education to explore and implement for the effective provision of distance education programmes. The purpose of this study was to investigate the role of mlearning as part of distance education and to develop guidelines for the management of mlearning in an open distance learning model. The aims of this study are thus to determine the role of m-learning in open distance education, identifying challenges to implement mlearning as part of an open distance learning model and finally to develop generic management guidelines to implement m-learning as part of open distance education. Quantitative research was undertaken using a survey questionnaire to acquire data for this research. The study population included students enrolled for distance education programmes at the NWU and accredited facilitators/lecturers employed by the NWU at tuition centres throughout SA facilitating distance education programmes. A total of 350 questionnaires (100 facilitators/lecturers questionnaire and 250 questionnaires for students) was sent out to all tuition centres to collect data for this research. Two different questionnaires were developed to suit the needs of each group. A total of 80.5% of completed questionnaires was returned. The literature study of this research included concept clarifications of distance education and m-learning. The need for effective management and organizational structures for the delivery of distance education programmes utilising m-learning were investigated to gain an understanding of the complexities associated with an open distance education modus. The information from the literature study and the empirical section of this research contributed to the development of generic guidelines to implement m-learning as part of an open distance education modus. In addition, aspects having an influence on the effective delivery of distance education programmes, were part of the questionnaires sent to respondents. These aspects included accessibility to resources utilising mobile devices, flexibility of programme delivery, affordability of programmes, interactivity between all role players in distance education and aspects that could influence anywhere and anytime learning. Furthermore, the different modes of delivering distance education programmes were explained. Challenges and barriers possibly having an influence in the delivery of distance education programmes through m-learning were included in the questionnaires sent out to respondents. Advantages
Obtaining Consistent Models of Helicopter Flight-Data Measurement Errors Using Kinematic-Compatibility and State-Reconstruction Methods

Abstract : A new method has been developed for application of Kalman Filter/ Smoothers to post-flight processing of helicopter flight test dynamic measurements. This processing includes checking for kinematic compatibility among the measurements, identification of a measurement error model, and reconstruction of both measured and unmeasured time histories. Emphasis is placed on identification of a parametric measurement error model which is valid for a set of flight test data. This is facilitated through a new method of concatenating several maneuver time histories. The method also includes a model structure determination step which ensures that a physically realistic parameterization has been achieved. Application of the method to a set of BO-105 flight test data is illustrated. The resulting minimally parameterized error model is shown to characterize the measurement errors of the entire data set with very little variation in the parameter values. Reconstructed time histories are shown to have increased bandwidths and signal-to-noise ratios. Keywords: BO- 105 Aircraft; West Germany helicopters.
The Visual Mandela Effect as Evidence for Shared and Specific False Memories Across People

The Mandela effect is an Internet phenomenon describing shared and consistent false memories for specific icons in popular culture. The visual Mandela effect is a Mandela effect specific to visual icons (e.g., the Monopoly Man is falsely remembered as having a monocle) and has not yet been empirically quantified or tested. In Experiment 1 (N = 100 adults), we demonstrated that certain images from popular iconography elicit consistent, specific false memories. In Experiment 2 (N = 60 adults), using eye-tracking-like methods, we found no attentional or visual differences that drive this phenomenon. There is no clear difference in the natural visual experience of these images (Experiment 3), and these errors also occur spontaneously during recall (Experiment 4; N = 50 adults). These results demonstrate that there are certain images for which people consistently make the same false-memory error, despite the majority of visual experience being the canonical image.
Effects of Short-Term Intensive Balance Training for the Performance Ability of Lower Extremities in the Elderly

The objective of this study was to discern the effects of a balance training program on the performance of lower extremities in order to improve strength (muscle power, flexibility, walking power), balance control and walking ability in the elderly. The subjects selected were aged 65 years and over, with no known relevant medical history that may disturb their balance, and have also been visiting the Gimhae Senior Welfare Center. The variable group consisted of 30 subjects, of whom were people who had been participating in balance training programs (One Leg Standing; OLS, Functional Reach; FR, Timed Get Up and Go; TUG) as an intervention for 8 weeks 3 times per a week. They were examined in order to identify their balance control before and after. The control group consisted of thirty subjects who preferred to exercise without any intervention relating to balance training program. The subjects were measured before and after balance training in order to determine the effectiveness of exercise and the effectiveness of exercise combined with the aid of a Balance Performance Monitor. 1. Mean time on OLS test with left and right sided extremities in the experimental group was 35.44 sec, 42.10 sec longer than control group respectively. In FR tests applied to the left and right side, mean reaching distance was increased up to 5.56 cm, 6.73 cm in experimental group respectively. Mean time on TUG test from a chair in experimental group was decreased to 2.33 sec. 2. Mean value of decline in the level balance control, both left and right side, decreased to 2.24% as examined by the Balance Performance Monitor. Mean scores for sway level after balance training decrease to . 98% and for balance control both anterior and posterior directions decreased to mean 1.07% and 1.44%, respectively.
Evaluation of Sperm Chromatin Integrity Using Aniline Blue and Toluidine Blue Staining in Infertile and Normozoospermic Men

Background: Male infertility is defined as a man lost his ability to fertilize a fertile female naturally. Diagnosis of male infertility cannot be made just according to basic semen analysis. It is necessity to have specific tests for evaluation of chromatin integrity. In this study, an attempt was made to evaluate the sperm chromatin quality in fertile men and infertile subgroup. Methods: Among 1386 couples, 342 men were categorized into normospermia and 1044 were infertile and they were referred to Yazd Research and Clinical Center for infertility treatment. Standard semen analysis and sperm nuclear maturity tests including aniline blue (AB) and toluidine blue (TB) staining were done. Data were analyzed by SPSS software. The p≤0.05 was considered statistically significant. Results: The mean value of TB staining was significantly higher in infertile group compared to normospermic group (p=0.005). Mean of sperm normal morphology was lower in idiopathic infertile men in comparison with normozoospermic men (p= 0.001). The highest negative correlation was obtained between sperm count and AB staining. Progressive motility was negatively correlated with AB and TB staining in both groups but there was no significant difference between AB staining and progressive motility in men normospermia group. Conclusion: Sperm chromatin staining using AB and TB showed a negative association between sperm chromatin condensation with sperm count, normal morphology and progressive motility. It seems that the AB and TB test may be useful for the assessment of male fertility potential.
Study and mitigation of epistemological obstacles in the technological disciplines of higher education in Madagascar: Case of industrial technical drawing

In the past five years, ENSET has experienced a drop in the number of student teachers in the mechanical engineering department, the subject of a question in teaching practice supposedly uncertain and unsuitable for the present era. Our ambition is to invest in the search for certain elements blocking the teaching-learning of technological sciences, the case of technical drawing, which is the basis of all industrial and civil engineering construction work on which students approach less and the reason a strong presence of lexical and syntactic errors in the recommended tasks. ENSET is the only supplier of trainer-technicians in Madagascar, even the Indian Ocean, and the gradual loss of players in the mechanical engineering sector would generate an imbalance in production which would also lead to severe shortages of teaching staff in training establishments users of the ENSET product (vocational training centers, technical and general colleges, .).
Improvement in Yield and Assurance in Power Performance for Quarter- Micron Optical Gate 8V Power pHEMT Technology

A low cost and production worthy, 0.25 m optical gate 8V power pseudomorphic high electron mobility transistor (pHEMT) technology using i-line stepper is developed. With increased photo resist thickness, yield exceeding 95% is demonstrated for devices with 12.5mm gate width across a 6-inch GaAs wafer. In addition, no drain current degradation under the breakdown stress over time test is observed. We find that the Al content of the AlGaAs Schottky plays an important role in current drop phenomenon. Psat of 21.7dBm with PAE of 53.0% and linear gain of 15.6dB is achieved at 10GHz with VDS=8V.
Technical Paper 5: Energy modelling of a mid 19th century villa - Baseline performance and improvement options

Assessment of a traditional, two-storey sandstone villa in terms of its energy performance and internal comfort conditions. Dynamic thermal modelling will be used rather than Steady State calculation methods in an attempt to record results from an alternative software testing technique. The performance of this building, located in Fife, is intended to provide generic results for traditionally constructed buildings with high thermal mass. The results will attempt to show that the two main issues are with heating system operational profiles and insulation has been added to the traditional construction. Providing insulation within existing walls for example would be considered to negate the effects of thermal mass however thermal mass works even though insulation is in between the construction. With the use of modern central heating, buildings with high thermal mass favour small boilers working at maximum output and therefore efficiency - longer periods of operation at lower output. Conversely, buildings with low thermal mass tend to have much wider changes in temperature and the boiler can cycle on and off constantly.

INVESTIGATION OF DIGITAL DATA COMMUNICATION SYSTEMS

Abstract : Analyses are presented on a variety of topics related to the transmission of digital data. The performance of several types of Phase Shift Keyed (PSK) systems, as determined by the relationship of the error probability to signal-to-noise ratio, is examined. Coherent, differentially coherent, binary and m-state PSK systems, and the effects of frequency offset, cross-talk and thermal noise on the performance of these systems are considered. The performance of m-state differentially coherent multiplexed PSK data links operating over a Rayleigh fading tropospheric scatter link is analyzed. The properties of impulse noise are examined and the effect of impulse noise on digital systems using close packed codes are investigated. Moment detection, which refers to a decision technique based on the use of temporal moments is investigated both analytically and experimentally.
