ANALYSIS OF ABSTRACT REASONING FROM GRADE 8 STUDENTS IN MATHEMATICAL PROBLEM SOLVING WITH SOLO TAXONOMY GUIDE

This research was a descriptive research. Description of research result was presented quantitatively and qualitatively. Subjects of the research were 30 (thirty) 8th graders of SMPN 10 (State Junior High School) in Semarang, Indonesia. Data were collected through tests, documentation, observations, and interview. Student answers documents were observed and analyzed with SOLO Taxonomy guidance. The objective of the study was to analyze and provide an interpretation of students abstract reasoning level in cognitive development based on intended learning outcomes. The result of findings from students’ answers basically showed that students' abstract reasoning on the lower, middle and upper level, was alike to stages of structure complexity improvement. There were two main changes from concrete thinking to abstract thinking: quantitative stage (uni-structural and multi-structural) occurred first, as the number of details in student responses increased and then changed qualitatively (relational and extended abstract) because the detail was integrated into a structural pattern.
Factors influencing parasite load in male ornate tree lizards (Urosaurus ornatus): throat colour, population density, and habitat type

Parasite load can lead to numerous fitness consequences within a host, and often varies widely between individuals of a population under the influence of numerous physiological and environmental factors. Male ornate tree lizards present a complex form of colour polymorphism on their extensible throat fan, which is indicative of their dominance and territoriality. If males exhibiting territorial behaviour suffer testosterone-derived immunosuppression or stress associated with territorial behaviour, this could increase their parasite loads. Population density may also increase parasite loads as a result of increased probability of transmission between individuals, or reduced immune function resulting from density-dependent territorial interactions. Levels of parasitism within a particular habitat can affect the quality of the habitat for the host. Habitat type may influence parasite load as a result of the suitability of the habitat for the completion of the parasite’s life-cycle. I examined these three competing, although not mutually exclusive, hypotheses in six wild populations of male ornate tree lizards (Urosaurus ornatus) in the Chiricahua Mountains of Arizona. I compared the chigger (ectoparasite) and Plasmodium (haemoparasite) loads in individual males 1) with different throat colours, 2) from six populations varying in density, and 3) from one of either two habitat types (a treed riparian habitat and a creek bed). Parasite loads did not differ significantly between males of different throat colours or between males from different habitat types. Chigger loads decreased significantly with population density, although the effect size was very small, and Plasmodium levels did not vary significantly with density. I did not find support for any of the three hypotheses, but more data need to be collected on non-territorial males and overall host density (including other lizard species in the area) before reaching more definitive conclusions about the effects of throat colour and population density on parasite load.
Error correcting neural networks for channels with Gaussian noise

The main features of error correcting codes and standard decoding techniques are reviewed. Feedforward neural networks for soft-decision decoding of block codes in channels with additive white Gaussian noise are presented. When the noise is not white, the authors deduce the optimal set of weights for the connections of the network. These weights are also approximately obtained by an error backpropagation algorithm. A practical realization for a BCH
Differences in response to “No bones about it!” between boys and girls

Conklin, Amy, "Differences in response to " No bones about it! " between boys and girls" (2009). CFS Honors Program Undergraduate Theses. Paper 2. INTRODUCTION Early adolescence is a critical time for skeletal development, as this is when maximal bone growth occurs (1). Development of bones mass during adolescence can help reduce the risk for childhood fractures and osteoporosis later in life. Low calcium intakes can contribute to poor bone health and can increase the risk of developing osteoporosis (2). An adequate intake of 1300 milligrams per day of calcium was set for both male and female adolescents by the Institute of Medicine (3). Unfortunately, most adolescents do not attain this recommendation. Thus, researchers have aimed to investigate various effectively reaching young people to adopt healthy behaviors, such as improving calcium intake and bone health, which is particularly challenging. Industry estimates that 45 million homes have video-game consoles and the majority of users are teenagers (4). Whereas computer games are often associated with inactivity (5), emerging research suggests that computer games may provide an avenue for providing prevention health messages for cancer, diabetes, obesity, and other health problems (6). Computer games directed to the improvement of children's health are still in their infancy (7). Most of the multimedia-based interventions that exist today focus on fruit, vegetable, and fat intake (8). Studies on other dietary components also may be useful in improving health and preventing health risk behaviors. The role of computer-based games as learning tools for increasing awareness of bone-related health risks and improving bone health in early adolescents has not been scientifically studied. An examination of computer-based games as a learning tool is needed to evaluate whether interaction with a game directed to changing behaviors might guide adolescents to develop plans to improve their calcium intakes. Delivering health content via multimedia and computer games has several advantages when compared to traditional teaching methods, such as lectures, textbooks, and videos. Using Conklin 2 multimedia and computer games to deliver health content can allow for interactive learning, which has been shown to be highly effective (9). The fidelity of the messages and content of the lessons can be protected, when health education is delivered with multimedia and computer games. This is particularly important, as it can help prevent the messages and content from transitioning into misinformation or information being dropped entirely due to a teacher's lack of confidence about a topic. …
Antimycobacterial and Antiplasmodial Activities of extract of Propolis from Different Region in Java (Indonesia)

The antimycobacterial and antiplasmodial activities of ethanolic extracts of propolis were evaluated after a preliminary phytochemical screening of extract. The antimycobacterium activity assay employed the disc-paper method, while the in-vitro antiplasmodial activity assay used the SYBR green methods. The result of the disc-paper method is the propolis extract, starting from 10 mg, has antimicrobial activity against Mycobacterium tuberculosis and the strongest one is from propolis of Sukabumi (West Java) which has hindrance zone of 22.01 mm when the dose is 20 mg. The in-vitro antiplasmodial activity assay shows that the propolis extract of from Lawang (IC50 37.34 ±1.23 µg/mL for P. falciparum strain D6 and 89.45 ± 2.13 µg/mL for strain W2) is better than the ones from Sukabumi (IC50 215.23 ± 2.32 µg/mL P. falciparum strain D6 and 453.23 ± 3.45 µg/mL for strain W2) and Batang (IC50 189.98 ± 1.34 µg/mL P. falciparum strain D6 and 356.89 ± 2.34 µg/mL for strain W2) tested by SYBR Green I methods. The conclusion: The propolis extracts from several areas in Java has antimycobacterial and antiplasmodial activities.
THE OPTIMAL DEMAND FOR FOREIGN EXCHANGE RESERVES IN PAKISTAN

Using monthly data on foreign exchange reserves from June 1995 through June 2005, we find that in line with other country-specific studies the opportunity cost of holding reserves played a greater role than reserve volatility in determining the level of reserves in Pakistan. Our finding is in contrast with the hypothesis of increased capital mobility that is commonly set forth in explaining the precautionary motive for reserve holdings. As also pointed by Ramachandran (2004), this result could perhaps be attributed to the fact that capital outflow in Pakistan (as also in India) is not as free as capital inflow and a large part of the recent reserve accumulation is due to non-debt reserve inflows.
Changes in the interannual variability of the tropical Pacific as a response to an equatorial Atlantic forcing

Previous studies have reported that the tropical Atlantic has had an influence on tropical Pacific interannual variability since the 1970s. This variability is studied in the present work, using simulations from a coupled model in the Indo-Pacific but with observed sea surface temperature (SST) prescribed over the Atlantic. The interannual variability is compared with that from a control simulation in which climatological SSTs are prescribed over the Atlantic. Differences in the Pacific mean state and in its variability are found in the forced simulation as a response to a warming in the equatorial Atlantic, characterized by a cooler background state and an increase in the variability over the tropical Pacific. A striking result is that the principal modes of tropical Pacific SST interannual variability show significant differences before and after the 1970s, providing new evidence of the Atlantic influence on the Pacific Ocean. Significant cooling (warming) in the equatorial Atlantic could have caused anomalous winds in the central-easter Pacific during the summer since 1970s. The thermocline depth also seems to be altered, triggering the dynamical processes involved in the development of El Nino (La Nina) phenomenon in the following winter. An increase in frequency of Nino and Nina events favouring the Central Pacific (CP) ones is observed in the last three decades. Further analyses using coupled models are still necessary to help us to understand the causes of this inter-basin connection.
Predictive digital control of power factor preregulators using disturbance observer for input voltage estimation

The paper present a fully digital control of single-phase boost power factor preregulators (PFPs) based on inductor (or switch) current and output voltage measurements. Input voltage sensing is avoided using a disturbance observer, which provides a waveform proportional to the rectified input voltage. The proposed solution is based on a multiloop structure for PFP with an internal deadbeat current control and an outer voltage control with fast dynamic response. The resulting control algorithm is simple, accurate and robust respect to parameter mismatch. The digital control has been implemented both in a field programmable gate array (FPGA) and in a DSP (TMS320F2812), so as to test the proposed algorithm with different control delays. Experimental results on a single-phase 500 W boost PFP show the effectiveness of the proposed solution.
Prediction of Pilot’s Absenteeism in an Airline Company

RESUME : Les compagnies aeriennes sont soumises aux nombreuses sources de perturbations pendant les operations. Il est essentiel pour ce type d'industrie de predire les origines des perturbations dans les differents niveaux de gestion pour reduire les couts de rattrapage du calendrier. Une des sources les plus importantes et couteuses de perturbation dans les compagnies aeriennes est l’absenteisme des pilotes au moment de l’operation des vols. ‎Dans ce memoire, nous nous concentrons sur l'absenteisme des pilotes pour cause de maladie. Nous proposons une methode d'apprentissage supervise qui est capable de predire la somme mensuelle des heures de maladie chez les pilotes apres la publication du calendrier. La methode proposee utilise les caracteristiques du calendrier mensuel comme les variables explicatives et elle fait la prediction en utilisant d’un algorithme iteratif. La methode a ete verifiee avec des donnees reelles et une amelioration considerable a ete observee dans les resultats. Pour rendre la methode en situation reelle, nous avons cree une interface facile a utiliser comme un systeme d'aide a la decision. Cette interface automatise l'ensemble du processus de prediction. ----------ABSTRACT : Airline companies are subject to a considerable number of disruptions during operations. It is vital for this type of industry to predict the source of disruptions in different levels of management to reduce the costs of schedule recovery. One of the most important and costly source of disruption in the airlines is absenteeism of the pilots at the time of the flights operation. In this master thesis, we focus on the absenteeism of the pilots because of the sickness. We propose a supervised learning method which is able to predict total monthly sick hours after publishing the schedule. The proposed method uses characteristics of the monthly schedule as the explanatory variables and the prediction is made by using an iterative algorithm. The model was tested with real data and a substantial improvement was observed in the results. For applying this method in business environment, we created a user-friendly web application as the decision support system. This application automates the whole process of prediction.

As variaveis taxas respiratorias, pH, valor L*, pectina soluvel, atividade de PME e PG, foram interativamente afetadas pelos fatores tipo de corte e tempo de armazenamento. As variaveis perda de massa, atividade da fenilalanina amonia-liase e a pectina total foram afetadas significativamente apenas pelo fator tempo de armazenamento. Pode-se concluir que a abobrinha 'Menina Brasileira' fatiada apresentou uma maior acidez titulavel e solidos soluveis e uma menor taxa respiratoria, pectina soluvel e atividade da fenilalanina amonia-liase, em comparacao com abobrinha ralada, contribuindo para a preservacao dos atributos de qualidade.
Unravelling structural fabric — a necessity for realistic rock mass characterisation for deep mine design

In recent years, there has been a spate of quite unexpected major failures within surface and underground mines that have significantly compromised mine stability and resulted in sustained loss of production. In the majority of these cases, evidence suggests that incipient, weak, generally incoherent structural fabric within the rock mass played a significant role in influencing the failure development. With the trend towards underground mines going ever deeper, and many of the large open pits transitioning to block cave operations, more focus is needed on gaining better structural geological understanding of incipient rock mass fabric within and outside the mining block so that such failure risks can be minimised. Current trends towards mine scale quantification of rock mass characteristics and development of local and regional scale discrete fracture network simulations, as basis for generation of synthetic rock mass models based on rigorous quantification of geological fabric assessments, is allowing better appreciation of the variability within a rock mass. However, comprehensive understanding of key elements of the geological fabric is often missing. This can lead, in worst case scenarios, to situations when the resulting models cannot be expected to capture the controlling mechanisms. This paper presents several structural geology techniques that are not widely known, or even commonly applied, either for large deep open pit design studies or for deep high stress underground mining. These techniques have merit for aiding risk minimisation for deep excavation through improved insight. Guidelines are provided for using fault striae data and applying stress inversion, slip tendency and critical stress evaluation approaches for advancing understanding of past and present day stress states — both key factors important to establishing the current stability state of major geologic structures transecting or bounding large surface or underground mining extraction blocks. Some techniques for estimating likely risk for inducing adverse slip on incipient geologic structures, potentially affected by mining, are also explored in the final sections of the paper.
Cohesion and Adhesion Interlayer of the Thermal Barrier Coatings Made of Cobalt Alloy MAR-M509

The manuscript presents microstructure, geometrical product specification and results of scratch tests performed on the interlayer of thermal barrier coating (TBC) with Rockwell's intender. The TBC was provided by depositing two layers; metallic interlayer and external ceramic layer onto a plate coating made of cobalt alloy MAR-M509 in plasma spraying process. The surface of the casting was sandblasted with Al2O3 powder in an air stream before the TBC was introduced. Scratches were made along the cross-section from a mould material (MAR-M509) through metallic interlayer and external ceramic layer in the TBC. Friction force, friction factor and acoustic emission were recorded during the test. It has been proved that metallic interlayer in the TBC of ca. 200 μm thickness forms tough coating without pores with good cohesion values and very good adhesion values to the mould.

A strategy initiated in 2010 to support and improve the retention rate of diverse cohorts of accelerated nursing students at two QUT campuses continued to be successful in 2012. An additional procedure involving the formation of learning communities was trialled in 2012 to address the social dimension of learning and assist in enhancing the quality of accelerated nurse’s first year university experience. A supported formative assessment activity was planned to allow the students to collaborate in learning communities.
BACTERIAL Cr (VI) REDUCTION AND ITS IMPACT IN BIOREMEDIATION

ABSTRACT Chromium is hazardous pollutant for ecosystem caused chromium especially in hexavalent form is very toxic, has high solubility and mobility, teratogenicity, mutagenicity and carcinogenicity to living system related with its oxiding power. Remediation of soil contaminated of heavy metals was important caused soil as medium for food producing. Conventional methods for heavy metals remediation consist of physical and chemical process but these applications were costly and less effective. One of the remediation technologies is the using living organisms such as microorganisms, because they have ability to reduce Cr(VI) into non toxic form, Cr(III). The aims of this research were to evaluate the reduction activity of rhizobacterial isolate and to identify the isolate which take a role in reducing chromium absorption by plant. The results showed that Isolate 39 was able to grow on LB medium containing 200 ppm Cr(VI). Isolate 39 reduced Cr(VI) up to 15 ppm concentration level in minimal medium. Isolate 39 has ability to reduce Cr(VI) both at growing cells and resting cells conditions up to 100% and 51% within 18 hours, respectively. Isolate 39 increased the phytostabilization ability of chromium by Zea mays at 30 days after seeding 3.8 times compared than control. Based on physiological characteristics and partial sequencing of 16S rRNA gene, Isolate 39 was identified as Agrobacterium sp. Key words : Agrobacterium sp, hexavalent chromium, reduction, Zea mays
Grand Unification from a Classical Interpretation of “Spin” Angular Momentum

It is shown from the laws of conservation of energy and angular momentum that the gravitational energy of a bound state particle is dependent upon its geometric mean angular frequency. A classical interpretation for the intrinsic “spin” angular momentum of a particle is submitted that can be tested macroscopically with the Rarita−Schwinger equation for the orbit of Mercury. Librations in the relative obliquity of planetary bodies are shown to be analogous to the Larmor precession of atomic particles. Schrodinger's concept of a bound state electron's zitterbewegung is hypothesized to be the librations in the electron's relative obliquity.
A Process for Keeping Pace with Evolving Web Mapping Technologies

The current pace of technological innovation in web mapping offers new opportunities and creates new challenges for web cartographers. The continual development of new technological solutions produces a fundamental tension: the more flexible and expansive web mapping options become, the more difficult it is to maintain fluency in the teaching and application of these technologies. We addressed this tension by completing a three-stage, empirical process for understanding how best to learn and implement contemporary web mapping technologies. To narrow our investigation, we focused upon education at the university level, rather than a professional production environment, and upon open-source client-side web mapping technologies, rather than complementary server-side or cloud-based technologies. The process comprised three studies: (1) a competitive analysis study of contemporary web mapping technologies, (2) a needs-assessment survey of web map designers/developers regarding past experiences with these technologies, and (3) a diary study charting the implementation of a subset of potentially viable technologies, as identified through the first two studies. The process successfully achieved the practical goal of identifying a candidate set of web mapping technologies for teaching web mapping, and also revealed broader insights into web map design and education generally as well as ways to cope with evolving web mapping technologies.
Are Greeks’ Unconcerned about Ethical Market Choices?"

An Ethical Unconcern (EthU) scale was constructed and its impact on Positive Ethical Consumption was examined. The procedure of EthU included literature search, brainstorming and discussion groups to generate the preliminary pool of 99 items, refinement of the scale via a students’ survey by the employment of item-to-total correlation and alpha-if-item deleted techniques. The initial scale was tested in a consumer survey conducted in the urban area of Thessaloniki, Greece. Item-to-total correlation and alpha-if-item deleted techniques were applied again, followed by Exploratory Factor Analysis (EFA) by the employment of PCA. The procedure left 21 items in five factors with eigenvalues greater than 1 explaining 61.34% of the variance. The five factors were named Boycott/ Discursive, Fair-Trade, Scepticism, Powerlessness and Ineffectiveness. The AMOS SPSS was then used to conduct confirmatory factor analysis. Goodness-of-fit results indicated that the measurement model fit the data well ( χ 2 = 594.226 , p<0.000, CFI=0.926, NFI=0.899, TLI=0.910, RMSEA=0.066). The examination of the Positive Ethical Consumption indicated rare to occasional ethical buying choices among Greek consumers. The inhibiting role of Ethical Unconcern on Positive Ethical Consumption was found to be rather low.
