Grinding Wheel Modeling : Development of a mathematical Model

Grinding wheels are complex tools with a structure composed of geometrically undefined abrasive grain material, a bonding material and pores. The statistically shaped grains and their distribution define the performance of the tool. Detailed models of the grinding wheel structure do not exist. A model based design of grinding wheels has a great potential to reduce cost and time consuming experiments to identify a suitable grinding wheel composition. This paper describes an approach to model the structure of grinding wheels, based on an analysis of real abrasive grains. A new methodology to evaluate the grain shapes based on computer tomography scan data using a marching cubes algorithm is presented. Besides, a basic model to visualize the structure of volumetric structure elements of a grinding wheel is shown using randomized polyhedrons, calculating the distribution of the grains and the collision distance. The presented work is a first step to generate a realistic model of complex grinding wheel structures based on the composition of the abrasive layer.

For this research all academic achievement results of pilot schools adapting digital textbook from 2008 to 2012 were collected and meta-analysis was conducted to verify systematically. The result of this research showed that digital textbook was effective in improving academic achievement. In order for digital textbook to be more effective in learning it is necessary to clarify the characteristics of each subject and to fully reflect them on digital textbook.
User friendliness and building automation-A conceptual approach to understanding perceived control

Building automation systems provide potential to optimise the energy consumption of buildings as well as to detect failures in the operation of buildings. Providing the occupants with control over the indoor environment is widely accepted to positively affect the occupant’s satisfaction. The system buildingHVAC-automation-user is becoming more complex. So what does the term ‘perceived control’ really mean? Psychological constructs from social learning theory and personality psychology transferred to the field of personal control of the indoor environment will be discussed. There are already several models describing man-environment interaction or the importance of control for persons. These models exist in parallel and have not been interconnected and translated into models for the built environment, yet. The aim of this paper is to show how these models could be interconnected and to develop a conceptual approach explaining the role individual control plays for user satisfaction.
Streptomycetes associated with marine sponges collected from Andaman Sea and Its antibacterial activity

Aims: Sponges harbour diverse prokaryotic and eukaryotic microbes. However, diversity of sponge-derived Actinomycetes is of high interest because of its bioactive compounds. In the present study, diversity of Streptomycetes associated with marine sponges collected from Pongibalu (south Andaman) was investigated. Methodology and results: Sponges samples were collected by underwater SCUBA diver and Kuster’s agar media was used for isolation of actinobacteria. Colony morphology and 16s rRNA were studied for identification of isolates and phylogenetic tree was constructed using MEGA.6. A total of ten Streptomyces species were identified based on 16S rRNA gene sequencing from three sponge species (Hemiasterella spp. Tentorium spp. and Tethyopsis spp.). The organic extracts of these ten isolates revealed bioactivity against tow Gram positive and eight Gram negative pathogenic bacteria. Conclusion, significance and impact of study: This study suggests prospects and potentials of the diverse population of Streptomyces with bioactivity in marine sponges. It would be a potential source in the pharmaceutical industries. As well as actinobacteria associated with sponge may prevent the sponge from pathogenic bacteria, fungi, virus and other microflora by secretion of secondary metabolites on surface and inside. To understand the sponge and actinobacteria association and its bioactivity, a profound study need to be conducted.
Defining Dusun Identity in Brunei

[ Abstract ] This qualitative study was designed to explore the definition of ethnic identity of the Dusuns in Brunei Darussalam from the perspective of Shamsul A.B. ’s (1996) “everyday-defined” social reality. The purpose of this study was twofold. Firstly, by employing Phinney’s (1996) formulation of ethnic identity, this study examined the existence of core components of ethnic identity, namely, ethnic self-identification, ethnic involvement, positive attitude towards ethnic group, and sense of belonging in the life of the Dusuns. Secondly, by utilizing Phinney’s (1996) three-stage model of ethnic identity formation, this study investigated the relationship between core components and the formation process of ethnic identity. Twenty-six Dusun informants ranging in age from 8 to 80 years old were interviewed for the purpose of this study. The analysis of the interview data revealed that all core components exist and evolve in the life of the Dusuns. Different perspectives towards core components can also be identified across different age groups. Adult informants contested the relevance of ethnic involvement in view of socio-cultural transformations that occurred within
4 Putting the evidence in evidence-based policy

Evidence-based policymaking presumes good evidence. This chapter considers what policymakers can do to enable and encourage the production of such evidence. The core of the chapter reviews the current state of knowledge on alternative ways of estimating the causal effects of programs and policies. While we highlight the value of social experiments, we also make clear that opportunities exist for increasing the quality of the evidence provided by nonexperimental evaluations through improvements in policy design and implementation, in the collection of survey data and in administrative data systems. We lay out the role that policymakers can play in exploiting these opportunities. The chapter also considers programs that affect non-participants as well as participants, cost–benefit analysis, potential substitutes for econometric evaluation such as performance management and customer satisfaction, and institutional changes that could improve the quality of evaluation
STRONG MOTION SIMULATION OF THE 2001 GEIYO ( MJ 6 . 7 ) , JAPAN , EARTHQUAKE BY EMPIRICAL METHODS

In this study, I carried out source parameter estimation and strong motion simulation of the 2001 Geiyo earthquake (MJ6.7), Japan. Data obtained at 10 KiK-net stations located at 19 to 66 km in epicentral distance is used. To focus on the source modeling from near-field records without consideration about nonlinearity of soft surface layers, borehole records are targeted. First, to derive rough estimates of basic source parameters, I inverted spectral amplitude from the S-wave main portion of the mainshock and 12 aftershocks (MJ3.5 to 5.0). The moment magnitude, the corner frequency and the stress drop for the mainshock were estimated to be 6.3, 0.5 Hz and 377 bar, respectively. Next, using data from the largest aftershock (MJ5.0) as the empirical Green’s function, I estimated the relative moment release distribution on the fault plane and simulated the strong motion records targeting the mainshock in a range of 0.3 to 10 Hz. Waveform matching between synthesis and observed data seems to be satisfactory. The maximum amplitudes of observed horizontal components from 10 stations were in a range between 1.6 and 8.5 kine in velocity. At most of the stations, the observed maximum amplitudes were simulated within a factor of 2.

Effective and competent methodologies have been developed for surveying and modeling archaeological sites and thus provide high quality and accurate realistic textured models for better research, preservation, education and monitoring projects. A specific methodology was applied to produce a scale 3D model of “Arutela (Căciulata) Roman Castrum” in a digital environment. A complex product is created, with complemental geometry and texture. The accurate geometry and appearance details (size, shape, position and texture) can be used for a proper documentation, preservation and restauration applications.
Effect of upstream building arrangement and setback distance on air flow around idealized cubical building arrays

The modification of flow pattern and mean wind profile in a built-up area due to upstream buildings can be quiet significant on the breathability of an urban area. Due to this circumstance, this paper aims to numerically evaluate the effects of the upstream building configuration and the upstream distance on the upwind building area at pedestrian level respectively. The analysis and evaluation of the upstream effect over the idealized buildings arrays was performed using the Large Eddy simulation (LES) method with a fine grid of =H/32. The air flow over staggered uniform cubical arrays was simulated under two different upstream arrangements, squared and staggered. Both the upstream building and upwind arrays were arranged with a plan area ratio of λp =25%. In addition, the distance between the upstream building and the upwind building was varied with a distance of 4H and 6H. By increasing this distance, the generated recirculation and isolated vortex will enhance the efficiency of the ventilation performance. Whereas, the staggered area shows that a wider passage width will influence the ventilation performance better than a squared pattern. This natural ventilation analysis is an important consideration for future urban development that may be needed by building physic engineers.

Callus induction from leaf explants of Gerbera jamesonii

In present study, leaves of Gerbera jamesonii were used as explants for callus induction. Sterilization of explants was done by washing with bavistin (0.2 %) for 7-8 minutes followed by HgCl2 (0.1 %) treatment for 3-4 minutes. This was the best treatment for sterilization as it produced maximum percentage of uncontaminated cultures. Callus induction was observed from leaf explants on Murashige and Skoog (MS) medium supplemented with 1.0 mg/l 2,4-D, 1.0 mg/l NAA, 2.0 mg/l IBA. Maximum callusing was found with this medium. Time required for callus initiation from leaf explants ranged from 17-18 days. Color of callus from leaf explants varied from light yellow to light green.
Nonlinear Dynamics of Second Mode Waves on a Hypersonic Flared Cone

A numerical analysis of spectral broadening of second mode waves over a hypersonic flared cone, designed to maintain a constant thickness boundary layer, was conducted through a comparison between direct numerical simulations (DNS) and nonlinear parabolized stability equations (NPSE). The current simulations show that the constant thickness focuses the spectrum of the second mode on one frequency band centered around 300 kHz; its amplitude grows by approximately 8 orders of magnitude over 0.45 m of cone length. This growth is shown to trigger nonlinear mechanisms such as mean flow distortion and spectral broadening, as expected. The DNS and NPSE exhibit very good agreement for the growth rates estimated for the principal frequency and the first two harmonics although the spatial location of the beginning of the growth differs for the higher frequency harmonics. It is also shown that the “rope waves” observed in Schlieren images in previous experiments of hypersonic transition are connected to the region of high nonlinear interaction of the second mode, where the pressure fluctuation amplitude is in the order of 50 Pa. This work is an intermediate step towards studying the relative importance of the different nonlinearities present in this flow and the energy source of the second mode waves at very high amplitudes.
Correlation among Snpb 11 markers , root growth , and physiological characters of upland rice under aluminum stress

Fendiyanto MH, Satrio RD, Suharsono, Tjahjoleksono A, Miftahudin. 2019. Correlation among Snpb11 markers, root growth, and physiological characters of upland rice under aluminum stress. Biodiversitas 20: 1243-1254. The cultivation of upland rice in acid soils faces aluminum (Al) toxicity. Development of Al-tolerant rice could be one of the solutions to overcome the problem. Markerassisted breeding to develop Al-tolerant rice requires at least a molecular marker for foreground selection. Snpb11 is a molecular marker developed from the nucleotide differences in a specific allele between Al-tolerant and sensitive rice. Snpb11 has never been used as a molecular marker in rice. Therefore this study aimed to examine the correlation among Snpb11 marker, root growth, and physiological characters under Al stress in upland rice. We used physiological characters and the Snpb11 marker to justify the Al tolerance level in several upland rice varieties. We found that physiological characters, i.e.: primary root length, total root length, chlorophyll, and carotenoid content showed positive correlation to Snpb11. Conversely, root malondialdehyde content, which represents the level of lipid peroxidation showed a negative correlation to Snpb11. There is evidence that the Snpb11 highly correlated with primary and total root length characters, which are the Al tolerance parameters used in rice. Therefore, Snpb11 markers can be used to distinguish the Al tolerance level in upland rice.
Inter-individual Variability in CAF : A Case Study of Two Individuals and Two Pairs

Mahboobeh Saadat Sahar Zahed Alavi (Corresponding author) Department of Foreign Languages and Linguistics Shiraz University, Iran ABSTRACT The present study tracked the development of general measures of complexity, accuracy and fluency (CAF), and specific measures of accuracy and complexity in the writings of two EFL learners writing individually, and those of two pairs of EFL learners writing in pairs within the framework of dynamic systems theory. The individuals and the pairs were similarly asked to do 7 tasks during a semester. The learners’ developmental pathways as well as the differences between individuals and pairs in terms of general and specific measures of CAF across the 7 tasks were depicted through graphs. Results indicated that the performance of learners in each of the measures was non-linear during the semester. Moreover, concerning general measures of CAF, learners writing individually outperformed in terms of fluency and complexity features. However, no clear distinction emerged in terms of general accuracy measures of their writings. Furthermore, development of general and specific accuracy measures in the writings was consistent. However, although it was found that the learners writing individually outperformed in terms of general measure of complexity, this developmental pattern was not evident in their performance in terms of specific complexity measures.
A theory of continuous improvement, designed to facilitate learning and innovation between the for-profit and the not-for- profit sectors

The initial spark for this research came from two related projects with organisations operating in differing sectors. The first project, for a for-profit organisation, had the stated aim of “introducing a culture of continuous improvement” into the organisation. The second, for a not-for-profit organisation, was less well-defined, but essentially aimed to improve the performance of a charity store, by increasing revenue (proceeds) to support the charity.

Weighted Iterative List-Mode Reconstruction for the High Resolution Research Tomograph

An attenuation/normalization weighted iterative list-mode reconstruction algorithm with random events correction was developed and implemented for the depth-encoding high resolution research tomograph. The final goal is to compare frame-mode versus list-mode reconstructions including all corrections to address time-cost for a specified image quality. As a first step, we have checked that list-mode reconstructed images are comparable statistically with images generated by 3D-OSEM for a wide range of random coincidences. List-mode reconstruction was also parallelized successfully on a Linux cluster.
The Effects of Supply Chain Strategies on Supply Chain Performance of Malaysian Manufacturing Companies with Moderation of Six Sigma and Lean Production

Since researchers and practitioners alike have focused on the importance of superior supply chain performance, this study examined which supply chain strategies are more likely to enable manufacturers achieve superior supply chain performance, and whether lean production and Six Sigma can play a moderating role and leverage the effects of mentioned strategies on supply chain performance. This research is a descriptive exploratory project in which primary data was collected from 80 Malaysian manufacturing companies. Data were analyzed by applying bivariate correlation and multiple regressions and indicated that two strategies (many suppliers and few suppliers) can have positive and strong effects on achieving superior supply chain performance, but vertical integration strategy. In addition, outputs show that lean and Six Sigma can be considered as a strong moderator just for improving the impact of vertical integration on superior supply chain performance.

COMBINED EFFECTS OF SALINITY , RICE VARIETY AND RICE GROWTH STAGE ON THE DIVERSITY OF BACTERIAL COMMUNITIES ASSOCIATED WITH RICE ( Oryza sativa L . )

The combined effects of salinity, rice variety, and rice growth stage on the diversity of bacterial communities associated with rice were analyzed using a molecular approach. Samples were taken from a field experiment that was set-up from January to May 2011 at the International Rice Research Institute (IRRI). Culture-independent isolation of total rhizosphere DNA was performed using a commercially available soil DNA extraction kit while the modified CTAB method was used to isolate the cultivable microbial community DNA from culture enrichments from bulk soil, rhizosphere, and sterilized root samples. The V6 to V8 region of the bacterial 16s rRNA gene was amplified through Polymerase Chain Reaction (PCR) and the amplicons were separated using Denaturing Gradient Gel Electrophoresis (DGGE). Rhizosphere bacterial diversity, measured by the Shannon index, was significantly higher under saline conditions compared to normal conditions. Diversity at the reproductive stage was also significantly higher than the vegetative stage. Combined DGGE profile and sequence analysis of the cultivable bacterial community revealed that salinity has a strong influence on the bacterial diversity in the bulk soil. The influence of crop growth stage on the bacterial community was more evident in the rhizosphere while the effect of salinity on specific microbe-plant interactions were observed in surfacesterilized roots. Salt-tolerant varieties were able to maintain association with bacteria that are reported to have plant-growth promoting properties even under saline conditions.
