Physical Separation of Motion into Three Categories for Evaluating the Behavioral Effects of Drugs in Mice

Characterization of open-field behavior and locomotor activity is widely used to assess the influence of a drug on animal behavior. In this study, we developed an index to characterize the behavior of drug-administered mice (C57BL/6). A three-exponential-model exhibited the best fit to the log-log plots of moving duration vs. frequency data of the different probability density functions. Therefore, as a heuristic argument, we divided each walking event into three categories according to the duration of movement. Then, we examined the number of walking events, and travel distances in each walking categories. Significant differences were observed more often when walking events were divided into the three categories. Therefore, this process would be useful to detect the effect of drugs on locomotor activity in mice.
Impact of Prostaglandin F2 on Silk Quality and Biosynthesis of Silk Proteins of the Silkworm, Bombyx mori 1

Effects of prostaglandin F2 on cocoon variables and biosyn- thesis of silk proteins were investigated in the multivoltine silkworm, Bombyx mori L. Increases in biochemical constituents, including total proteins, free amino acids, RNA content, glutamate dehydrogenase activity, and fibroin con- centration in the posterior silk gland after treatment with prostaglandi nF 2, corresponded to increases in whole cocoon weight, shell weight, shell ratio, and silk quality. The weight of the posterior silk gland increased significantly by 24.4% after treatment with prostaglandin F2. Cocoon weight and cocoon shell weight increased significantly by 5.0 and 16.4%, respectively. Total protein and free amino acids in the posterior silk gland increased significantly by 26.1 and 29.6%, respectively. RNA content increased significantly by 30.5%. Glutamate dehydrogenase activity of the posterior silk gland content increased significantly by 20.0%.
Adaptive Feature Extraction with Spike Coding for ANN Based Phoneme Recognition

Most speech recognition systems rely on spectral based features or others derived from them (e.g. Mel frequency cepstral coefficients). These features are usually adjusted according to the psychoacoustic properties of the human or human-like auditory systems obtained by real-life experimentation. However, since the auditory system is not completely understood, these modifications are not entirely accurate and further improvements can be achieved. Several attempts of finding optimal features for speech recognition have already been made, either through artificial evolution or gradient descent of different parameters in conventional feature sets. This research explores the possibility of deriving such features in a single process together with an ANN model for recognizing phonemes, commonly used in hybrid speech recognition. Special attention is paid to features extracted with spike coding mechanisms, which are known for their sparseness and efficiency and exhibit many similarities with auditory processing in the brain. The adaptation of these features is inspired in how our own auditory system learns to recognize sounds, but it is also supported by a lot of research that shows the similarity of features derived by adaptation and their counterparts derived from physiological and psychological experimentation. The research is still a work in progress so final results are yet unknown.
Effects of Geographic Information System on the Learning of Environmental Education Concepts in Basic Computer-Mediated Classrooms in Nigeria.

This research paper specifically examined the impact of Geographic Information System (GIS) integration in a learning method and on the performance and retention of Environmental Education (EE) concepts in basic social studies. Non-equivalent experimental research design was employed. 126 pupils in four intact, computer-mediated classrooms were sampled. Instruments included Envi-Geo Info System (EGIS) package and Environmental Information Achievement Test (EAT). The study found no significant effect of treatment on performances of participants in EGIS integrated treatment groups. No significant effect was found across the groups on pupils retention even though, treatment groups retention mean was higher than contemporaries. The study concluded that, adaptation of EGIS into sorted EE concepts will improve learning and might boost retention even in computer-mediated social studies classroom provided the use of GIS is made feasible in Nigeria and adopted into teaching-learning process. It recommended that stakeholders in Nigerian education system should foster workable strategies to improve teaching and learning and that, the use of GIS locally must be placed in the national education objectives. It is in the best interest of the people to learn the rudiments of personal safety, spatial development, incidental natural alerts, as well as preventions and solutions.
A Comparative Study of Levels of Job Satisfaction among Librarians in Private and Public Universities in Ondo State, Nigeria

This study focused on the job satisfaction levels of librarians in private and public universities in Ondo State, Nigeria. Questionnaires were distributed to respondents which elicited responses which were used to compare the job satisfaction levels of librarians in public universities with their counterparts in the private universities. The research procedure used was total enumeration of all academic librarians in public and private universities in Ondo State, Nigeria. A total of twenty nine (29) questionnaires were administered of which six (6) were administered in private universities while twenty three (23) were administered in public universities. Responses were analyzed using the T-Test statistical procedure and results were presented in tables. The study revealed that there was no significant difference in the level of job satisfaction of librarians in both private and public universities when compared on the basis of factors such as salary, library policies and administration, co-workers relationship, among others. Conclusions were drawn and recommendations were made that would enhance the level of job satisfaction among librarians in private and public universities in Nigeria.

Self-catalyzed, pure zincblende GaAs nanowires grown on Si(111) by molecular beam epitaxy

We report on the Au-free molecular beam epitaxy growth of coherent GaAs nanowires directly on Si(111) substrates. The growth is catalyzed by liquid Ga droplets formed in the openings of a native oxide layer at the initial growth stage. Transmission electron microscopy studies demonstrate that the nanowires are single crystals having the zincblende structure along their length (apart from a thin wurtzite region directly below the Ga droplet), regardless of their diameter (70--80 nm) and the growth temperature range $(560--630\text{ }\ifmmode^\circ\else\textdegree\fi{}\text{C})$. We attribute the observed phase purity to a much lower surface energy of liquid Ga than that of Au-Ga alloys, which makes triple line nucleation energetically unfavorable. The change in growth catalyst to a liquid metal with a lower energy suppresses the (more usual) formation of wurtzite nuclei on surface energetic grounds. These results can provide a distinct method for the fabrication of chemically pure and stacking-fault-free zincblende nanowires of III-V compounds on silicon.
The polyphasic description of a Desmodesmus spp. isolate with the potential of bioactive compounds production

Description polyphasique d’un isolat de Desmodesmus spp. presentant un potentiel dans la production de composes bio-actifs. L’approche polyphasique a ete utilisee pour decrire une espece de Desmodesmus formant des colonies. Il s’agit d’un isolat collecte dans le Nil, Aire de Maadi, district de Helwan en Egypte. Cet isolat croit le mieux a temperature moderee tout en etant expose a une relativement forte intensite lumineuse. Les caracteres phenotypiques revelent la presence a la fois de cellules et d’agregats cellulaires comptant de 2 a 4 cellules. Les cellules presentent une largeur maximale de 4-6 µm ± 0,5 pour une longueur de 11-15 µm ± 0,48. Elles sont pourvues de projections epineuses. Les cellules ont un aspect fortement granuleux et elles sont contenues dans un etui mucilagineux commun. Les formes en colonies se developpent par la production de cellules filles au sein de la cellule mere. L’analyse moleculaire utilisant le gene 18S rRNA montre une certaine similarite avec Desmodesmus communis qui en est l’organisme le plus proche dans la banque de donnees. L’analyse phylogenetique regroupe bien cet isolat avec les autres Desmodesmus spp. , tout en l’ecartant des Scenedesmus spp. de la base de donnees. La composition en acides gras revele la presence de l’acide palmitique sature comme le composant majeur suivi de l’acide palmitoleique (acide gras monoinsature), alors que les acides gras polyinsatures sont peu abondants. L’acide palmitoleique en particulier est suppose etre implique dans un mecanisme de defense active. Le criblage phytochimique revele la presence d’alcaloides et de saponines ainsi que l’absence de tannins. Les fractions d’extraits methanoliques montrent des activites antimicrobiennes contre des souches de bacteries pathogenes, y compris celles multiresistantes aux antibiotiques. Cette etude documente la presence de cette souche de Desmodesmus dans le Nil et met en evidence son potentiel biotechnolologique comme source de composes bio-actifs.
Functional Studies of HSPA5 Promoter Polymorphisms and Risk of Essential Tremor in Taiwan

Endoplasmic reticulum (ER) stress induced by misfolded proteins and a malfunction of unfolded protein response (UPR) to ER stress have been implicated in neurodegenerative disease pathogenesis. Heat shock 70 kDa protein 5 (HSPA5) is one of the UPR chaperones reactive to ER stress to block the apoptotic process. Three polymorphisms in the HSPA5 promoter region, -415 G/A (rs391957), -370 C/T (rs17840761) and -180 del/G (rs3216733), may affect the gene expression. Using a reporter assay, we examined the functional implication of these three promoter polymorphisms. Reporter construct containing the polymorphic -415 A allele cloned into a luciferase reporter plasmid drove significantly lower transcriptional activity of HSPA5 compared with the common -415 G allele in human neuroblastoma SK-N-SH cells. The association of these polymorphisms with Taiwanese essential tremor (ET) was investigated using a case-control study. The genotype, allele or haplotype frequency distribution examined was not significantly different between the controls (n = 341) and the ET patients (n = 130). Our data suggest that while functionally, the HSPA5 -415 G/A polymorphism is unlikely to affect susceptibility to ET in Taiwanese subjects.
The Influence of Knowledge Management on Business Value in IT Projects: A Theoretical Model

This paper develops a theoretical model to explain the relationships between knowledge management and business value in IT-enabled business projects. It draws upon a wide range of literatures including project management, management information systems, software engineering, organization and management theory, organizational behaviour and strategy. The overall model comprises two sub-models. The first shows how the alignment of three project-based knowledges directly influences business value. The second shows how four knowledge-based concepts, knowledge management, knowledge stock, enabling environment, and knowledge practices, combine to create the project-based knowledges. Together these two sub-models provide an overall model of the causal system through which knowledge management influences business value. This research makes contributions to the research into IT Projects by (1) integrating fragmented literatures which connect knowledge management and project success; and (2) proposing for discussion a predictive model in which knowledge management influences business value. It has the potential when further developed to clarify what project managers can do to manage knowledge in a systematic way.
Acid-base properties and structons: towards a structural model for predicting the thermodynamic properties of silicate melts

Phase equilibrium relationships in igneous systems can be estimated using empirical mathematical models based on multi-component regular solution formulae. Although these provide useable results within the fitted region, they can give very misleading values outside the compositional range of curve fitting. Moreover, they usually give poor estimates of the well-characterized melting relations of simple systems and do not relate to the large body of thermodynamic activity data available in the metallurgical literature, nor to spectroscopic, diffraction or computational models of silicate melt properties. The aim of this paper is to extend previous acid-base models of silicate melts and to use a quasi-chemical model to calculate the activities of quasi-chemical silicate mixing units, or structons, from combinations of the oxo-species used in quasi-chemical and polymer models to calculate oxide activities in metallurgy.
Assessment of heavy metals (Cu, Ni, Fe, Co, Mn, Cr, Zn) in rivulet water, their accumulations and alterations in hematology of fish Channa punctatus

The present study was conducted to examine the contamination of rivulet situated at Kasimpur, Aligarh (27.218° N; 79.378° E). It receives the wastewater of Harduaganj Thermal Power Plant (HTPS) containing fly ash and heavy metals. Among the heavy metals estimated in the rivulet water, Fe (8.71 mg L-1) was present in the highest concentration followed by Cu (0.86 mg L-1), Zn (0.30 mg L-1), Mn (0.21 mg L-1), Ni (0.12 mg L-1), Co (0.11 mg L-1) and Cr (0.10 mg L-1). The values for the heavy metals such as Fe, Ni and Mn were beyond the limits set by UNEPGEMS. Channa punctatus inhabiting the rivulet, bioaccumulate these heavy metals in tissues such as gills, liver, kidney, muscle and integument. Accumulation of Fe (140.2 to 1533.08 mg kg-1.dw) was highest in all the organs. The accumulation of Fe, Zn, and Mn, observed in the tissues were above the values recommended by FAO/WHO. Abnormalities in hematological parameters of exposed C. punctatus were also observed. The total RBC count (-51.39%) showed decline over control. Therefore, fall in Hb (-36.98%) and oxygen carrying capacity (37.00%) was also observed over control. On the contrary, the total WBC count (+25.43%) increased over control. Key words: Channa punctatus, effluents, heavy metals, bioaccumulation, hematology.
Pre-inverse Active Noise Control System Using Inverse Transfer Function Estimation of Secondary Path with Auxiliary Filter

We propose a pre-inverse active noise control (PIANC) in order to solve the unstable problem on a Filtered-x ANC (adaptive noise control). The PIANC uses the flat delayed signal instead of a filtered input signal. However, since the conventional PIANC uses a series adaptive system to estimate the inverse transfer function of a secondary path, the noise reduction ability is degraded due to bias error. Therefore, this paper introduces an auxiliary filter into the estimation of the inverse transfer function of the secondary path. The proposed method configures the bias free structure by taking advantage of the delay in the primary path. This paper shows that the proposed method has possibility to be superior to a Filtered-x ANC by simulation results. In addition, the proposed method is implemented by a DSP (digital signal processor).
Mastering New Information through Facebook and a Discussion Forum: A Comparative Analysis

This paper investigated the effect of productive failure (PF) as an instructional strategy in computer-supported collaborative learning (CSCL) groups using Facebook and a discussion forum. PF is an instructional mode design that advocates the delaying of support for the learners during learning — the more they struggle, and even fail, while trying to master new information, the better they are likely to recall and apply that information later. PF has been used successfully in the classroom. However, it is not known whether the use of a PF instructional modewith adult learners in CSCL groups such as Facebook and discussion forums will produce such a positive effect. A discussion forum is an important platform used to deliver teaching and learning via the Web, while the use of social media, especially Facebook, for teaching and learning has gained prominence lately. This paper reports an initial study that compares a ‘productive failure’ instructional design in CSCL groups through Facebook and a discussion forum. Five Facebook and five discussion forum groups participated in the study. Both groups solved ill-structured complex problems in small groups without the provision of any support or scaffolding from their instructors. The findings suggest that the Facebook groups produced a variety of scope for discussion and deliberation for solving the problems and were more successful in sustaining the discussion compared to the discussion forum groups. Facebook groups also had a higher critical thinking ratio than the discussion forum groups. Based on these findings,the implications of a PF instructional design for adult learners are presented.
Bringing Secrecy into the Open: Towards a Theorization of the Social Processes of Organizational Secrecy

This paper brings into focus the concept of organizational secrecy, defined as the ongoing formal and informal social processes of intentional concealment of information from actors by actors in organizations. It is argued that existing literature on the topic is fragmented and predominantly focused on informational rather than social aspects of secrecy. The paper distinguishes between formal and informal secrecy and theorizes the social processes of these in terms of identity and control. It is proposed that organizational secrecy be added to the analytical repertoire of organization studies.
Physicochemical treatment (coagulation-flocculation-Fenton) of mature leachates from Tuxtla Gutierrez, Chiapas landfill

Mature leachates are a significant cause of soil and water contamination because they contain high organic loads of recalcitrant materials. The application of a physicochemical process is normally insufficient to remove the organic load from these liquids. The objective of the study was to evaluate removal efficiencies in terms of Chemical Oxygen Demand in mature leachates from the Tuxtla Gutierrez landfill applying a physicochemica l Coagulation-Fl occulation-Fenton system. In the first stage, ferric chloride (FeCl ) and ferrous sulfate (FeSO ) coagulants were used at different doses (2.2, 34 -1
AGN spiral galaxies in groups: effects of bars

We explore properties of barred active spiral galaxies in groups selected from the SDSS-DR7, with the aim of assessing the effects of bars on AGN and the role of the high density environment. We identified barred active galaxies that reside in groups from SDSS-DR7 group catalog. To provide a suitable quantification of the effects of bars, a reliable control sample of unbarred active galaxies in high density environments with similar redshift, magnitude, morphology, and bulge size distributions was constructed. We found that the fraction of barred AGN galaxies in groups (~ 38 %) is higher than those in the total barred AGN sample ( ~ 28 %), indicating that AGN spiral galaxies in groups are more likely to be barred than those in the field. We also found that barred AGN galaxies are more concentrated towards the group centers than the other unbarred AGN group members. In addition, barred AGN host galaxies show an excess of population dominated by red colors suggesting that bars produce an importanteffect on galaxy colors of AGN hosts. The host groups of the barred AGN exhibit a larger fraction of red colors than the host groups of the corresponding unbarred active galaxies. Color-magnitude relations of both host groups of AGN differ significantly: the host group colors of barred active galaxies display distributions spreading toward red populations, with respect to the host groups of the unbarred AGN objects. Barred active galaxies show an excess of nuclear activity compared to galaxies without bars. We found that barred active galaxies located farther from the group-center have stronger Lum[OIII]. Our findings suggest that the efficiency of bars to transport material towards the more central regions of the AGN galaxies in high density environments reveals an important dependence on the localization of objects within the group and on the host group colors.
Analysis of Do-Not-Spam Registry

We study how the launching of a do-not-spam registry will affect the internet’s efficiency. We show that as long as the cost of sending spam messages is not high, having rich users (who have high-quality filters) join the registry has the desirable effect of lowering the number of spam messages sent to each user, while having poor users (who have low-quality filters) join the registry has the opposite undesirable effect. We also show that the registry improves the total efficiency of the internet - as long as the cost of sending spam messages is not high; as more users join, the total number of spam messages sent to all users decreases.
Empowerment of Remote Indigenous Community

Remote Indigenous Community (RIC) is an entity that must be managed wisely and RIC regional sustainability should be maintained. This study objective are: (a) analyzing the social and economic activities of RIC, (b) analyzing the Income level of RIC, (c) analyzing the welfare level of RIC, and (d) analyzing the community empowerment model of RIC. This research use primary and secondary data. Social and economic activities analysis is carried out by RIC descriptive to known income level analysis the difference between total revenue and total expenditure in agricultural business. Well-being level is analyzed by periodical welfare growth index value (Todaro, 2000). Model formulation of community empowerment is prepared by RIC potential. Research results show that RIC people's lives in Bombana heavily depend on farming (rice, corn, and a small portion of cashew). RIC welfare growth is 0.49 percent in 2004, and a decrease (-1.09 percent) in 2010, and increased again by 1.72 percent in 2013. Empowerment and economic capacity development of RIC in Bombana can be done through: a) utilization of land resources, b) ecological and cultural approaches, and c) institutional development.
Authenticity, nostalgia and taste : the interaction between Greek restaurants in Amsterdam and their clientele

This study explores the relationship between Greek restaurants in Amsterdam and their clientele. Through a discussion of how they engage with how cultures may be authentically portrayed within restaurants, how ethnic food affects the customer through synaesthetic nostalgic remembrance, and the significance of taste acquired through the habitus on the restaurant, this study ultimately endeavours to highlight this interaction, and how they influence each other. The essential conclusion this study came to was that these interactions guided the restaurants to become socially embedded within their cultural setting
Hydrogen sensing properties of doped and undoped TiO 2 nanotubes

In this work, we fabricated undoped and doped TiO2 nanotubes for investigating H2 sensor properties of these structures. Ti foil was anodized in an aqueous HF electrolyte (0.5 wt %) to form TiO2 nanotube arrays. Carbon doped TiO2 nanotubes were fabricated by anodization of Ti foil using %0.5 polyvinylalcohol (PVA) in an aqueous HF electrolyte (0.5 wt %). For both doped and undoped TiO2 nanotubes anodization was performed at a constant potential of 20V and at constant temperature of 20 oC. The two structures were characterized using scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray photoelectron spectroscopy (XPS), and determined the H2 sensing properties at 100 oC.
