Blind dating—mate finding in planktonic copepods. I. Tracking the pheromone trail of Centropages typicus

Mate-finding behaviour in the marine copepod Centropages typicus was investigated by 3-dimensional video analysis. Females leave a chemical trail in their wake and a male intercept- ing a fresh trail initiates a characteristic tracking behaviour in which he increases his speed from ~10 to ~30 mm s -1 and races up the female trail while displaying a tight zigzag motion. Within sec- onds the male overtakes the female and attempts to catch her. Males faithfully follow even very con- voluted trails and successfully track down females after pursuing trails up to 31 s old and 17 cm long. The probability of detecting a trail is inversely related to trail age and length. Males often start track- ing female trails in the wrong direction before correcting themselves, and the frequency of direc- tional errors increases with increasing trail age. Complicated or disrupted signal trails may cause males to lose the trail. This induces a distinct signal-scanning behaviour characterised by further enhanced swimming speeds of 50 to 70 mm s -1 , and frequent shifts of direction. The male scans a restricted volume around the point where the trail was lost and often regains the trail and resumes normal tracking behaviour. This behaviour may help males follow trails that are broken by turbu- lence. A simple generic model of pheromone trails that is consistent with the tracking behaviour of males in C. typicus and other species of copepods was used to explore the characteristics of pheromone trails. Model considerations suggest that these pheromones are small molecules, e.g. amino acids, and that the investment in pheromone production, both in terms of elements and metabolic energy, represents only a small fraction of the females' ingestion and metabolic rate.
Investigating Preservice Teachers' Literature Selection Process.

This paper examines the literature selection and evaluation practices of preservice teachers, investigating trends in choosing and acquiring literature and factors affecting the literature's appeal. Participants were undergraduate students enrolled in a language arts course for elementary school majors who completed a survey and attached it to a lesson plan and a reflection used that day. The survey asked why they picked the literature in their lesson plans, where they got it, what they liked most and least about it, and whether they would use it again. Students completed the survey three times during the term. Four students completed interviews regarding why they chose the literature, what factors appealed to them, how they would describe the selection process, how they evaluated literature, and what factors would discourage them from using literature. Overall, participants chose literature for many reasons, which varied as students were increasingly exposed to children's literature and the need for its use in class. There was a shift from the importance of current teaching topic and personal experience in literature selection to a more broad-based range of selection reasons from the first to the third survey. Illustrations were an important factor in the selection process, as were book and award lists. Over half of the literature selections came from the library. (SM) Reproductions supplied by EDRS are the best that can be made from the original document.

Flexible ligated ruthenium(II) self-assemblies sensitizes glioma tumor initiating cells in vitro

The tumorigenic potentials of residual cancer stem-like cells within tumors represent limitations of current cancer therapies. Here, the authors describe the effects of synthesized flexible, ligated, supramolecular self-assembled chair type tetranuclear ruthenium (II) metallacycles (2–5) on glioblastoma and glioma stem like cells. These self-assemblies were observed to be selectively toxic to glioma cells and CD133-positive glioma stem like cells population. Of the self-assembled compounds tested, metallacycle 4 more efficiently induced glioma stem like cells death within a brain cancer cell population and simultaneously inhibited the formation of free-floating gliospheres by reducing the sphere size. Detailed cell death studies revealed that treatment with metallacycle 4 reduced mitochondrial membrane potentials (an indicator of apoptosis) of glioma stem like cells. These results shows the elimination of cancer stem-like cells using an appropriate ligand binding adaptor offers a potential means of developing metal-based compounds for the treatment of chemo-resistant tumors.
THE ACTIVE CRUSTAL DEFORMATION FIELD OF THE AEGEAN AREA INFERRED FROM SEISMICITY AND GPS DATA

A model is derived for the deformation velocity and strain rate field of the broader Aegean area, using the most reliable available seismological and GPS data. The data are initially processed separately in order to define a continuous velocity field using polynomial fits to the original data and the obtained results show a very good agreement for the two data sets. Using this result, seismological and GPS data are jointly interpreted assuming that the seismic deformation represents a part of the total deformation, revealed by the GPS data and a common seismic-GPS deformation field is defined through a non-linear iterative process. The obtained seismic- to-total deformation ratio shows that in the strike-slip faulting areas (North Aegean Trough and Cephalonia) almost all deformation is expressed seismically, whereas the corresponding values are significantly smaller (around 20-40%) throughout the remaining Aegean area where normal faulting dominates. The final jointly determined deformation field is more detailed than previous estimations and further supports the idea that the Aegean should not be considered as a part of a single Anatolia-Aegean microplate, which has been suggested to perform an almost rigid body rotation. The rotational component of the obtained velocity field, shows a clockwise rotation in central and SW Aegean and an anticlockwise rotation in the SE Aegean, in very good agreement with the available palaeomagnetic data. A modified kinematic-tectonic model is presented for the Aegean, using the final deformation field, as well as the seismological and GPS information used in the study.
Numerical analysis of mixed convection characteristics inside a ventilated cavity including the effects of nanoparticle suspensions

A numerical study of mixed convection flow and heat transfer inside a square cavity with inlet and outlet ports is performed. The position of the inlet port is fixed but the location of the outlet port is varied along the four walls of the cavity to investigate the best position corresponding to maximum heat transfer rate and minimum pressure drop in the cavity. It is seen that the overall Nusselt number and pressure drop coefficient vary drastically depending on the Reynolds and Richardson numbers and the position of the outlet port. As the Richardson number increases, the overall Nusselt number generally rises for all cases investigated. It is deduced that placing the outlet port on the right side of the top wall is the best position that leads to the greatest overall Nusselt number and lower pressure drop coefficient. Finally, the effects of nanoparticles on heat transfer are investigated for the best position of the outlet port. It is found that an enhancement of heat transfer and pressure drop is seen in the presence of nanoparticles and augments with solid volume fraction of the nanofluid. It is also observed that the effects of nanoparticles on heat transfer at low Richardson numbers is more than that of high Richardson numbers.

INFLUENCE OF STRETCHING EXERCISE ON PERFORMANCE AND MOVEMENT TECHNIQUE DURING DROP JUMPS

The aim of this study was to verify the influence of a single flexibility training session on drop jump performance (vertical velocity at take off) and movement technique (joint angles and joint angular velocities). Thirty male subjects performed two drop jumps before and after four sets of quadriceps static stretching. A control session was made without stretching. The results showed an increase in ground contact time, an increase in knee and ankle joint flexion as well as an increase in knee maximal angular velocity during the eccentric and concentric phases. However, these changes in the movement technique have not affected the performance.
Exploring probabilistic differences between genetically related languages

The study proposes an analytical pipeline for quantitative corpus-based research in the domain of contrastive linguistic analysis. Specifically, it is proposed that a combination of conditional inference tree models for data exploration combined with subsequent statistical modeling via generalized linear models can help reveal and describe interesting contrasts between the languages under investigation. The main goal of this paper is to provide an approachable introduction into the rationale underlying these techniques and to illustrate their application on the basis of a contrastive analysis of English and German relative clause constructions.

Sections of the skin, gills and intestine of twenty randomly selected fish were aseptically removed by means of sterile scalpel and pair of sterile scissors. Four (4 g) of each sections were homogenized in cml of sterile distilled water, which served as the original stock culture. A Serial dilution of 109 was carried out, and surface plated on nutrient agar. A total of eighteen (18) bacteria specie were isolated and identified. Twelve (12) bacteria were identified to the specie level and six (6) to the genus level. Eleven (11) were Gram positive namely. Bacillus spp. ,, Staphylococcus spp. ,, Streptococcus spp. , Lactobacullus spp. , Clostridium spp. , Enterobacter aerogenes, Bacillus moratorium, Bacillus pumillus, Bacillus alvei, Bacillus licheniformis, Staphylococcus saprophyticus and Seven (7) Gram negative bacteria namely; Escherichia coli, Klebsiella pnemoniae, Pseudomonas alcaligenes Salmonella spp. , Listeria monocytogenes, Serratia mercescens and providential stuertii. The frequency of occurrences of the isolated Bacteria indicated that Bacillus alvei had the highest frequency occurrence (12.72%), while Salmonella spp. , had the least frequency occurrence (1.82%). The mean viable count from each sections of the samples revealed 50.1 × 107 Cfug-1 from the gills, 29.8 × 108 Cfug-1 from the isolates were found to be of medical importance to man.
Communication, Coordination and Collaboration: Media affordances and Team Performance in a Collaborative Design Environment

Advances in digital media are encouraging designers to adopt digital tools during early stages of design ideation as well as to facilitate collaboration in design teams. Collaborative environments for design teams should take into consideration both the multimodal nature of design representation as well as the complexity of team cognition. Collaborative tools that take a “black-box” approach often limit affordances for design ideation and collaboration. We describe here a collaborative environment that we put together using a kit-of-parts approach and underlying theoretical considerations. We also describe systematic usability evaluation of the collaborative environment by constraining select media affordances and qualitatively examining the impact on a team's design process. Preliminary findings were used to improve the environment and lay the groundwork for developing tele-collaborative environments.
Identification and primary characterization of a plant antimicrobial peptide with remarkable inhibitory effects against antibiotic resistant bacteria

On the basis of a primary screening scheme by using plant seed methanol extract against a collection of human pathogenic bacteria, Medicago sativa L. seeds were chosen as the best potential resource against tested Gram positive bacteria. Then an agar-overlay method using fully separated proteins on sodium dodecyl sulphate-polyacryliamide gel electrophoresis (SDS-PAGE) gels was used for initial determination and primary characterization of active putative defensins in the plant seeds. Clear and remarkable zones of inhibition in a region corresponding to peptides slightly larger than 6 kDa were recorded for Methicillin resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococcus faecium (VRE) strains and yeast but a smaller inhibition zone with several colonies for tested Gram negative strain of Escherichia coli . Further characterization experiments using two-dimensional gel electrophoresis and subsequent agar-overlay assay against both strains confirmed the peptide nature of the active substance. Also gel filtration separation using Sephadex G-25 superfine and subsequent antibacterial assays could confirm the presence of a low molecular weight anti-MRSA and anti-VRE peptide in the total water soluble proteins obtained from M. sativa L. seeds which also showed high level of thermo stability. Key words: Medicago sativa L. , methicillin resistant bacteria, vancomycin resistant bacteria, plant defensins.
Changes in Benthic Algal Community Structure Following an Unpredictable Stream-Wide Desiccation Event

Rex L. Lowe, Advisor Global climate models predict future temperature and precipitation conditions that will increase the likelihood of unpredictable drought in currently perennially-flowing stream ecosystems. In this study, an experiment using artificial streams examined the impact that unpredictable desiccation and rehydration have on lotic periphyton community structure. 23 day-old periphyton communities were slowly desiccated and rehydrated over the course of two weeks, and changes in cell density and community composition were analyzed. Results indicated that a catastrophic loss of cell density occurred during desiccation, as most diatoms were eliminated and blue-green and green algal densities were severely depressed. The remaining desiccated periphyton community was dominated by blue-green, and to a lesser extent, green algae. After a 24-hour rewetting period, a 3-fold increase in cell density occurred and blue-greens continued to dominate the community. Immigration analysis indicated that immigrant cells could not have been solely responsible for the increase in cell density, suggesting that reproduction was more important during recovery. Cell health data revealed unique kingdom-specific responses to desiccation: diatom cells were empty, green algae exhibited some cellular damage, and bluegreen algal cells were mostly healthy. The results of this study suggest that in streams that lack any history of seasonal desiccation, catastrophic loss of all periphyton occurs during drought, but blue-green and green algae are relatively better at surviving and recovering from desiccation than diatoms.
An Exploration of Monophonic Instrument Classification Using Multi-Threaded Artificial Neural Networks

The use of computers for automated music analysis could benefit several aspects of academia and industry, from psychological and music research, to intelligent music selection and music copyright investigation. In the following thesis, one of the first steps of automated musical analysis, i.e., monophonic instrument recognition, was explored. A multi-threaded artificial neural network was implemented and used as the classifier in order to utilize multi-core technology and allow for faster training. The parallelized batch-mode backpropagation algorithm used provided linear speedup, an improvement to the current literature. For the classification experiments, eleven different sets of instruments were used, starting with perceptively dissimilar instruments (i.e., bass vs. trumpet), moving towards more similar sounding instruments (i.e., violin vs. viola; oboe vs. bassoon; xylophone vs. vibraphone, etc.,). From the 70 original musical features extracted from each audio sample, a sequential forward selection algorithm was employed to select only the most salient features that best differentiate the instruments in question. Using twenty runs for each set of instruments (i.e., 10 sets of a 50/50 cross-validation training paradigm), the test results were promising, with classification rates ranging from a mean of 76% to 96%, with many individual runs reaching a perfect 100% score. The conclusion of this thesis confirms the use of multi-threaded artificial neural networks as a viable classifier in single instrument recognition of perceptively similar sounding instruments.

Trimming Lithography: An Alternative Technology for Sub-Resolution and Sub-Wavelength Patterning

Lithography is one of the key technologies for scaling down a size of integrated circuits thus increasing the performance of an electronic device. Currently, there are many lithographic techniques that are potentially capable to produce a nanometer feature size but the continuing development for a commercial use is still limited by extremely high investment especially on exposure equipment and mask. This paper introduces an alternative patterning technique called Trimming lithography as one of the strong candidates for future lithography, for producing sub-resolution and subexposure wavelength features. The pattern size can be downscaled by carefully adjusting the trim distance that is much higher than an original design linewidth. It is shown that the photoresist (PR) feature size can be scaled down with the acceptable profile to approximately 0.18 m from the original 0.8 m mask pattern with the 0.5 m resolution of the exposure tool. However, the pattern density of the line/space pattern becomes lower than that of the typical lithography. Different pattern qualities between dense and isolated patterns are probably explained by a diffraction occurring during a transmission of light through the mask slit.

Investigating the Relationship between Knowledge Creation Process and Organizational Performance in a Service-Sector Organization

Today knowledge creation, an important part of knowledge management is an essential issue for success of every firm. But there are few researches which have investigated the role of this process on the performance of organizations. Thus to fill this gap this paper has tried to investigate the significance of knowledge creation process in improving the market, customer and financial performances of service sector organizations. To attain this goal this paper conducted the banking industry in Isfahan as one of the most important organizations in service-sector to investigate the nature of relationship between knowledge creation and organizational performance. In order to examine the main hypothesis Structural Equation Modeling (SEM) and Amos graphic have been used. The results imply that knowledge creation process can positively affect the performance of a service-sector organization.
Solving the Virtual Machine Placement Problem as a Multiple Multidimensional Knapsack Problem

Effective placement of virtual machines in a cluster of physical machines is essential for optimizing the use of computational resources and reducing the probability of virtual machine reallocation. Many of previous works treat virtual machine placement as an instance of the bin packing problem, as they aim at saving energy. Alternatively, we propose an approach based on the multiple multidimensional knapsack problem, where the main concern is to maximize placement ratio. Several traditionally employed placement algorithms were re-implemented and new algorithms were defined by using such an approach. The algorithms were evaluated with respect to placement ratio, by employing a novel evaluation method that contemplates variation of computational resources heterogeneity in multiple dimensions and also variation of placement density. The experimental results showed that heterogeneity of resources among physical machines impairs the placement ratio, while heterogeneity of resources among virtual machines benefits it. It was also possible to observe that increase of density placement up to a certain point benefits the placement ratio.
