to improve the students‟ vocabulary at SMA Negeri 4 Palopo?”. Based on the description, the research objective is to find out whether the use of Rustan Finger Games is effective to improve students‟ vocabulary at SMA Negeri 4 Palopo. The
research involved 14 students as the research sample through purposive sampling. This research employed a pre-experimental design and used a one-group pre-test and post-test. The researcher used pre-test and post-test to collect data and
analyzed it using SPSS 26. The findings showed significant differences between the pre-test and post-test scores, with the average pre-test score being 41.79 and the average post-test score rising to 81.07. The researcher used SPSS 26 to test the
hypothesis by conducting a paired sample t-test. The value of Tc (t-count) is 22.747, with the df (degree of freedom) value of 13. The significant value 0.05 on df (degree of freedom) value 13 is 2.160, which means the data stated that the value of Tc (t-count) is higher than the value of Tt (t-table), as follows 22.747>2.160. The result from the t-test showed that the significance value is
0.001, which is smaller than the P value standard 0.05 (0.001 < 0.05). On the other hand, hypothesis alternative (H1) is accepted, and hypothesis null (Ho) is rejected. Based on these results, the researcher concluded that Rustan Finger Games
effectively enhanced students' vocabulary
Automatic image processing and analysis of rock fragmentation-comparison of systems and new guidelines for testing the systems
No full textThe development of an automatic image processing and analysis system for rock fragmentation was started in Lulea in the beginning of the 1980's and the result was presented at Fragblast 1 (First International Symposium on Rock Fragmentation by Blasting) in Lulea in 1983. Since that, many countries like; Australia, Canada, France, Germany and USA have started their own development of automatic image processing and analysis systems. The ISRM Commission on Fragmentation by Blasting found that the time had come to make a state of the art report of the technique and the former ISRM President John Franklin was asked to arrange a workshop in connection to Fragblast 5 in Montreal in co-operation with Takis Katsabanis from Queens University, Ontario, Canada. Some principal data from Automatic image processing and analysis systems presented at the workshop are collected and compared in this paper. Also strategic issues regarding fragmentation analysis and the presentation of fragment size distributions, which were posted by the author of this paper in the poster session at Fragblast 5, are discussed after getting feed back from the participants. A proposal for an international testing procedure of the accuracy of the automatic image processing and analysis systems is presented.</p
Magnetic ordering and structural distortion in Ru-doped BaFe2As2 single crystals studied by neutron and x-ray diffraction
No full textWe present a systematic investigation of the antiferromagnetic ordering and structural distortion for the series of Ba(Fe1−xRux)2As2 compounds (0⩽x⩽0.246). Neutron and x-ray diffraction measurements demonstrate that, unlike for the electron-doped compounds, the structural and magnetic transitions remain coincident in temperature. Both the magnetic and structural transitions are gradually suppressed with increased Ru concentration and coexist with superconductivity. For samples that are superconducting, we find strong competition between superconductivity, the antiferromagnetic ordering, and the structural distortion.This article is published as Kim, M. G., D.

A multimethod experimental investigation of the effect of market price knowledge on acceptable price range
No full textThis dissertation reports a multimethod investigation of the relationship between market price knowledge and the width of the acceptable price range. Psychophysics and Social judgment theory are discussed as supporting the existence of acceptable price thresholds (limits) and acceptable price range. Hypotheses stemming from Social judgment theory are offered directly relating market price knowledge with the width of the acceptable price range.
The relationship between market price knowledge and acceptable price range was investigated using two different methods, the Stoetzel and the Own-Category method. Unlike the previous acceptable price limit studies, this research assessed the reliability and construct validity of each of those methods.
The research design used was a laboratory experiment with a series of 2 x 2 factorials based on the Solomon 4 group-six study design. The dependent variables were: (1) the acceptable lower price limit, (2) the acceptable upper price limit, and (3) the acceptable price range. The independent variable was market price knowledge. The two-way anova design had two factors. The first factor had two levels: absence and presence of market price knowledge. The second factor consisted of two levels: pretest and no pretest treatments.
The research hypothesis was tested using (1) two-way analysis of variance, (2) analysis of covariance using sex and prior price knowledge as covariates, and (3) paired t-tests.
Test-retest reliability of the two methods were assessed using Pearson's correlation coefficient. Pearson correlation coefficients were also used to set validity coefficients. Those coefficients were used to assess construct validity of the two measures in terms of convergent and discriminant validity within the context of Campbell and Fiske's multitrait-multimethod zero-order correlation matrix.
In general, the experimental results partially confirmed the hypothesis that the acceptable price range would be narrower for subjects possessing market price knowledge than for those subjects possessing little or no market price knowledge. The results of the Stoetzel method supported the hypothesis, but the hypothesis was not supported when the same subjects used the OwnCa Category method.
The results did support the hypothesis that the two methods were valid measures of ac~eptable price thresholds with the OwnCa Category method producing higher reliability scores than the Stoetzel method. Results of the dissertation are discussed with respect to the major findings and significance to price theory and research. The dissertation concludes with a discussion of the study limitations and directions for future research.Ph. D
Oxidation of intramyocellular lipids is dependent on mitochondrial function and the availability of extracellular fatty acids

Oxidation of intramyocellular lipids is dependent on mitochondrial function and the availability of extracellular fatty acids. Am J Physiol Endocrinol Metab 299: E14-E22, 2010. First published May 4, 2010; doi:10.1152/ajpendo.00187.2010.-Obesity and insulin resistance are related to both enlarged intramyocellular triacylglycerol stores and accumulation of lipid intermediates. We investigated how lipid overflow can change the oxidation of intramyocellular lipids (ICLOX) and intramyocellular lipid storage (ICL). These experiments were extended by comparing these processes in primary cultured myotubes established from healthy lean and obese type 2 diabetic (T2D) individuals, two extremes in a range of metabolic phenotypes. ICLs were prelabeled for 2 days with 100 mu M [C-14] oleic acid (OA). ICLOX was studied using a (CO2)-C-14 trapping system and measured under various conditions of extracellular OA (5 or 100 mu M) and glucose (0.1 or 5.0 mM) and the absence or presence of mitochondrial uncoupling [carbonyl cyanide p-trifluoromethoxyphenylhydrazone (FCCP)]. First, increased extracellular OA availability (5 vs. 100 mu M) reduced ICLOX by 37%. No differences in total lipolysis were observed between low and high OA availability. Uncoupling with FCCP restored ICLOX to basal levels during high OA availability. Mitochondrial mass was positively related to ICLOX, but only in myotubes from lean individuals. In all, a lower mitochondrial mass and lower ICLOX were related to a higher cell-associated OA accumulation. Second, myotubes established from obese T2D individuals showed reduced ICLOX. ICLOX remained lower during uncoupling (P <0.001), even with comparable mitochondrial mass, suggesting decreased mitochondrial function. Furthermore, the variation in ICLOX in vitro was significantly related to the in vivo fasting respiratory quotient of all subjects (P <0.02). In conclusion, the rate of ICLOX is dependent on the availability of extracellular fatty acids and mitochondrial function rather than mitochondrial mass
Gravity flow of broken rock : What is known and unknown
No full textThe knowledge in the field has been reviewed by literature studies, and using experience from personal research in sublevel caving. There is a lot of material regarding gravity flow of fine grained materials in bins, but the theory of flow for these materials are normally not applicable for coarse blasted rock. This study was therefore concentrated towards coarse rock fragments created after blasting in orebodies. The goal for this study was to make a report of known knowledge, and identify what we have to learn more about. The Bergmark-Roos theory, which was a paradigm shift in the science of gravity flow, is today the best mathematical theory for calculation of the drawbody for a homogenous material or when we wish to simulate the mean drawbody for a large number of draws. The Bergmark-Roos theory must however be improved, so it can take into account the flow pipe effect. When this is done it will be possible to construct a 3D computer model for calculation of ore extraction versus amount of loaded ore and waste. It is also necessary to find the 3D shape of the flow cone to be able to calculate the 3D ore rest that normally develops on footwalls. Calculations should be done for the draw on several sublevels including determination of the ore losses and temporary ore rests. First when this computer model is developed optimisation of ore recovery and waste rock dilution can start for a given orebody. The author points out the importance for international co-operation and standardisation of methods for determination of material properties. More field tests and model blasting tests should also be done. When enough knowledge is gathered, a handbook of the optimisation of sublevel and block caving should be written</p
Model Checking ω -Regular Properties with Decoupled Search
No full textDecoupled search is a state space search method originally introduced in AI Planning. Similar to partial-order reduction methods, decoupled search exploits the independence of components to tackle the state explosion problem. Similar to symbolic representations, it does not construct the explicit state space, but sets of states are represented in a compact manner, exploiting component independence. Given the success of both partial-order reduction and symbolic representations when model checking liveness properties, our goal is to add decoupled search to the toolset of liveness checking methods. Specifically, we show how decoupled search can be applied to liveness verification for composed Büchi automata by adapting, and showing correct, a standard algorithm for detecting lassos (i.e., infinite accepting runs), namely nested depth-first search. We evaluate our approach using a prototype implementation.</p

GPU Acceleration of Bounded Model Checking with ParaFROST
No full textThe effective parallelisation of Bounded Model Checking is challenging, due to SAT and SMT solving being hard to parallelise. We present ParaFROST, which is the first tool to employ a graphics processor to accelerate BMC, in particular the simplification of SAT formulas before and repeatedly during the solving, known as pre- and inprocessing. The solving itself is performed by a single CPU thread. We explain the design of the tool, the data structures, and the memory management, the latter having been particularly designed to handle SAT formulas typically generated for BMC, i.e., that are large, with many redundant variables. Furthermore, the solver can make multiple decisions simultaneously. We discuss experimental results, having applied ParaFROST on programs from the Core C99 package of Amazon Web Services.</p

ABSTRACT
We have previously shown that human skeletal muscle myotubes cultured in vitro, retain in vivo characteristics of the donors. Recent studies indicate that electrical pulse stimulation (EPS) can be used as an exercise mimetic in a cell culture model, and could be beneficial to understand molecular mechanisms underlying exercise training. Purpose: The purpose of this study was to compare acute, moderate and long duration EPS treatments on mitochondrial and lipid content in cultured myotubes. Methods: EPS stimulation was applied to human myotubes cultured from sedentary donors under three conditions: Acute (bipolar pulses of 100 Hz for 200 ms every 5th second; 30V for 60 min) and chronic stimulation (single bipolar pulses of 2 ms; 30V, 1Hz continuously for 24 h or 48 h). Mitochondrial and lipid contents were measured by primary antibody for complex IV and bodipy green dye, respectively, using immunohistochemistry techniques. Fluoroskan ascent microplate reader was used to quantify fluorescence signals. OXPHOS proteins were measured using western immunoblotting. Results: There was no change in lipid or mitochondrial content as assessed by immunohistochemistry after acute EPS stimulation. Chronic stimulation resulted in a significant increase in the mitochondrial content after 24 h (from 0.183 ± 0.02 AU to 0.350 ± 0.03 AU; p=0.008) and 48 h (from 0.290 ± 0.01 AU to 0.337 ± 0.01 AU; p=0.02) of continuous EPS stimulation. OXPHOS proteins increased after 48 h of EPS. There was also a significant increase in lipid content after 48 h of EPS stimulation (from 0.210 ± 0.01 AU to 0.256 ± 0.01 AU; p=0.02). Conclusion: These findings suggest that 48 h of chronic EPS results in an increase in both mitochondrial and lipid contents in human myotubes. The concomitant increase in lipid and mitochondrial content after exercise mimetic EPS stimulation supports the elevated level of intramyocellular lipid and mitochondrial content evident in endurance trained athletes
