Selective attraction of marine bacterivorous nematodes to their bacterial food

This paper explores the role of selective attraction to food in determ~ning the spatial (micro)distribution of closely related nematode species. The attractiveness of 3 different bacterial strains to 4 species of Monhysteridae, Diplolaimelloides rneyli. Diplolaimella dievengatensis, Monhystera sp. and Geomonhystera disjuncta, was studied in a multiple choice design. In our study area, the 4 nematode species considered are associated with Spartina anghca detritus decay and have partially overlapping microhabitat preferences. As they all belong to the same feeding guild, they are potential competitors for food. Each of the 4 nematode species was attracted to the bactenal strain B1, but important interspecific differences were noted in the nematodes' response to live or heat-killed bacteria, to bacteria at different cell densities or of different age, and to the filtered supernatant of B1 culture. While the responses of D. meylj to the Gram-positive bacteria Halobacillus trueperi and to the Gramnegative Eschenchia col1 \yere similar, D. dievengatensis and Monhystera sp. were preferentially attracted to H. trueperi and E. coli, respectively. This opposite preference influenced both the numbers and their relative abundances of D, dievengatensis and Monhystera sp. inside bacterial patches in experiments with a mixed 2-species nematode inoculum. Bacterial cell density strongly influenced the nematode response, \nth D. meyliinvariably preferring the highest cell densities offered, while D. dievengatensis and Monhystera sp. had a peak response at lower cell densities. Though chemotaxis IS suggested as an underlying mechanism, the nature of the nematodes' response remains unproved. The present results strongly support the importance of food patchiness in determining the heterogeneous distribution of nematodes, and extend the concept in such a way as to allow for small differences in mlcrohabitat choice between closely related species. They also support the view that nematodes are special~st feeders, though they probably select spots where suitable food is plentiful rather than individual food particles. Finally, the present study offers a baseline for an understanding and further study of patterns of succession among nematode specles associated with decaying Spartina anglica detritus in terms of highly specific relationships with different strains, growth stages, and densities of bacteria involved in the mineralization of Spartina anglica-derived organic matter.
Validation of Jason and Envisat Altimeter Dual Frequency Rain Flags

New rain flags based on the dual frequency capabilities of the new Jason Poseidon-2 and Envisat RA2 altimeters have been tested, developed and adopted for the operational processing of the altimeter data. Their validation conducted during the calibration/validation phases of the satellites is presented here. The Jason flag is validated by comparison with the TOPEX one, using the Tandem mission. The results show a very good agreement between the two sensors and the two rain flags The Envisat flag is validated by comparison with both Jason and TOPEX using global and collocated data sets. The results show similar performances for the three sensors. The f relations estimated during the calibration-validation period and presented here have been given to the altimeter ground processing facilities for operational use.

Multiple positive periodic solutions for a delayed predator-prey system with Beddington-DeAngelis functional response and harvesting terms

In this paper, a delayed predator-prey system with Beddington-DeAngelis functional response and harvesting terms is studied. By using Mawhin's continuation theorem, the sufficient conditions are established for the existence of at least four positive periodic solutions. Finally, an example is presented to illustrate the effectiveness of the results.
Towards BioDBcore: a community-defined information specification for biological databases

The present article proposes the adoption of a community-defined, uniform, generic description of the core attributes of biological databases, BioDBCore. The goals of these attributes are to provide a general overview of the database landscape, to encourage consistency and interoperability between resources and to promote the use of semantic and syntactic standards. BioDBCore will make it easier for users to evaluate the scope and relevance of available resources. This new resource will increase the collective impact of the information present in biological databases.
A Proposal to Detect Computer Worms (Malicious Codes) Using Data Mining Classification Algorithms

Malicious software (malware) performs a malicious function that compromising a computer system’s security. Many methods have been developed to improve the security of the computer system resources, among them the use of firewall, encryption, and Intrusion Detection System (IDS). IDS can detect newly unrecognized attack attempt and raising an early alarm to inform the system about this suspicious intrusion attempt. This paper proposed a hybrid IDS for detection intrusion, especially malware, with considering network packet and host features. The hybrid IDS designed using Data Mining (DM) classification methods that for its ability to detect new, previously unseen intrusions accurately and automatically. It uses both anomaly and misuse detection techniques using two DM classifiers (Interactive Dichotomizer 3 (ID3) classifier and Naive Bayesian (NB) Classifier) to verify the validity of the proposed system in term of accuracy rate. A proposed HybD dataset used in training and testing the hybrid IDS. Feature selection is used to consider the intrinsic features in classification decision, this accomplished by using three different measures: Association rules (AR) method, ReliefF measure, and Gain Ratio (GR) measure. NB classifier with AR method given the most accurate classification results (99%) with false positive (FP) rate (0%) and false negative (FN) rate (1%).
Efficient in vitro organogenesis and plantlets regeneration in sesame (Sesamum indicum L.)-an important oilseed crop

The regeneration methods in Sesame (Sesamum indicum L.) already developed were genotype dependent and were unsuccessful for Indian cultivars. Hence, an efficient protocol for in vitro organogenesis and plant regeneration in sesame was attempted with TMV 3 cultivar. Immature cotyledons derived from 1-week old seedlings were cultured on MS (Murashige and Shoog) medium fortified with different concentrations of 6-benzylaminopurine (BAP), thidiazuran (TDZ) and kinetin for adventitious shoot induction. It was found that optimal medium for direct shoot formation was MS with BAP (2.0 mg/l) at a frequency of 74% with an average of 4.5 shoots per expalnt. The shoot regeneration frequency was significantly reduced with either TDZ or kinetin when compared with BAP alone. Elongated individual shoots were transferred on MS media supplemented with Indole Butyric Acid (IBA; 0.5 mg/l) showed rooting frequency of 70%. The rooted plantlets were acclimatized to potting mixture containing sand, soil and clay mixture and grown to maturity with survival rate of 65 %. No phenotypic aberrations were observed among the ex vitro transferred plantlets. The protocol described here assures a high frequency of shoot regeneration, root induction and also plant survival rate.
Large dimensional empirical likelihood

The empirical likelihood is a versatile nonparametric approach to testing hypotheses and constructing confidence regions. However it is not clear if the famous Wilks’ theorem still works in high dimensions. In this paper, by adding two pseudo-observations to the original data set, we prove the asymptotic normality of the log empirical likelihood ratio statistic when the sample size and the data dimension are comparable. In practice, we suggest to use the normalized F (p;n − p) distribution to approximate its distribution. Simulation results show the excellent performance of this approximation.
Daily Living Functioning, Social Engagement and Wellness of Older Adults

Aim: The present study aim to investigate the contributing role of daily living functioning and social engagement in enhancing wellness and various dimensions of wellness in older adults. Method: A correlational research was designed. Socio-demographic data was collected. Lawton Instrumental Activities of Daily Living, Lubben Social Network Scale, and Perceived Wellness Survey were administered on a sample of 112 participants, including 56 men and 56 women. Results: A correlation analysis found positive correlations between daily living functioning, social engagement and wellness of older adults. The results of regression analysis concluded that both the daily living functioning and social engagement predicted wellness and domains of wellness as well. Conclusion: The obtained results indicate that older adults who are self-reliant lead a more satisfied life in old age and demonstrate to be more adjusted to the effects of aging.
Clumpy outer Galaxy molecular clouds and the steepening of the IMF

We report the results of high-resolution (0.2 pc) CO (1{0) and CS (2{1) observations of the central regions of three star-forming molecular clouds in the far-outer Galaxy (16 kpc from the Galactic Center): WB89 85 (Sh 2-127), WB89 380, and WB89 437. We used the BIMA array in combination with IRAM 30-m and NRAO 12-m observations. The GMC's in which the regions are embedded were studied by means of KOSMA 3-m CO (2{1) observations (here we also observed WB89 399). We compare the BIMA maps with optical, radio, and near-infrared observations. Using a clumpnd routine, structures found in the CO and CS emission are subdivided in clumps, the properties of which are analyzed and compared with newly derived results of previously published single-dish measurements of local clouds (OrionB South and Rosette). We nd that the slopes of the clump mass distributions ({1.28 and {1.49, for WB89 85 and WB89 380, respectively) are somewhat less steep than found for most local clouds, but similar to those of clouds which have been analyzed with the same clumpnd program. We investigate the clump stability by using the virial theorem, including all possible contributions (gravity, turbulence, magnetic elds, and pressure due to the interclump gas). It appears that under reasonable assumptions a combination of these forces would render most clumps stable. Comparing only gravity and turbulence, we nd that in the far-outer Galaxy clouds, these forces are in equilibium (virial parameter 1) for clumps down to the lowest masses found (a few M). For clumps in the local clouds 1 only for clumps with masses larger than a few tens of M. Thus it appears that in these outer Galaxy clumps gravity is the dominant force down to a much lower mass than in local clouds, implying that gravitational collapse and star formation may occur more readily even in the smallest clumps. Although there are some caveats, due to the inhomogeneity of the data used, this might explain the apparently steeper IMF found in the outer Galaxy.
The Pedagogic Signature of the Teaching Profession

Lee S. Shulman deplores that the field of education as a profession does not have a pedagogic signature, which he characterizes as a synthesis of cognitive, practical and moral apprenticeship. In this context, the following study has three goals: 1) In the first theoretical part, the basic problems of constructing a pedagogic signature are depicted. 2) In the empirical part, based on a multi-method approach, teachers’ and teacher educators’ beliefs and attitudes about a pedagogic signature are identified and ranked. It is argued that beliefs are of particular importance because they have a filter effect on how teachers deal with scientific knowledge. 3) The third part, the discussion, explains the findings, particularly the fact that moral aspects and aspects referring to a particular attitude play an overwhelming role. The explanation leads to some basic considerations on how to construct a pedagogic signature and on how such a signature can be turned into a viable concept for teacher education.

N IH -P A A uhor M anscript N IH -P A A uhor M anscript N IH -P A A uhor M anscript Background—Adolescent drinking is an important public health concern, one that is influenced by both genetic and environmental factors. The functional variant rs1229984 in alcohol dehydrogenase 1B (ADH1B) has been associated at a genome-wide level with alcohol use disorders in diverse adult populations. However, few data are available regarding whether this variant influences early drinking behaviors and whether social context moderates this effect. This study examines the interplay between rs1229984 and peer drinking in the development of adolescent drinking milestones. Methods—1,550 European and African American individuals who had a full drink of alcohol before age 18 were selected from a longitudinal study of youth as part of the Collaborative Study on the Genetics of Alcoholism (COGA). Cox proportional hazards regression, with GxE product terms in the final models, was used to study two primary outcomes during adolescence: age of first intoxication and age of first DSM-5 alcohol use disorder symptom. Results—The minor A allele of rs1229984 was associated with a protective effect for first intoxication (HR=0.56, 95% CI 0.41–0.76) and first DSM-5 symptom (HR=0.45, 95% CI 0.26– 0.77) in the final models. Reporting that most or all best friends drink was associated with a hazardous effect for first intoxication (HR=1.81, 95% CI 1.62–2.01) and first DSM-5 symptom (HR=2.17, 95% 1.88–2.50) in the final models. Furthermore, there was a significant GxE interaction for first intoxication (p=.002) and first DSM-5 symptom (p=.01). Among individuals reporting none or few best friends drinking, the ADH1B variant had a protective effect for adolescent drinking milestones, but for those reporting most or all best friends drinking, this effect was greatly reduced. Conclusions—Our results suggest that the risk factor of best friends drinking attenuates the protective effect of a well-established ADH1B variant for two adolescent drinking behaviors. These findings illustrate the interplay between genetic and environmental factors in the development of drinking milestones during adolescence.
Presence of depression in patients with asthma and its influence on their families

In this article we examine and review investigations that study the possible presence of depression among patients suffering from bronchial asthma. Throughout the article we provide possible explanations about the relationship between bronchial asthma and depression found in psychological literature along with their possible repercussions in the evolution, morbidity control, and treatment of the illness. Likewise, studies that have investigated depression in families of teenagers and children with bronchial asthma are reviewed. In order to do that, the investigations have been extracted from some of the most widely used databases in Psychology concerning this topic (Web of Knowledge, EBSCO, Psycodoc, Cindoc, Psycarticles and Google Scholar). Finally we offer some reflections about the data analyzed, in the sense that there is enough empirical evidence to confirm that the rates of depression among asthmatic patients and their families are significantly larger than among their asthma-free peers.
Accelerated pavement testing of load transfer through aggregate interlock and the influence of crack width and aggregate type - a case study

It is well known that performance of plain jointed concrete pavements depends on aggregate interlock to transfer load from the one slab to the next. In order to quantify the relative contribution of crack width and the strength of the aggregate to the longterm performance of a plain jointed pavement, experimental sections of road were built using different aggregates types. These sections were subsequently loaded to failure using the Heavy Vehicle Simulator (HVS). Some typical sections of interstatetype highways, which had been under traffic for between ten and twenty years were also investigated using FWD testing and determination of changes in crack width with changes in temperature. Detailed as-built information including concrete mix characteristics was available for all these sections. This paper discusses the prediction of crack width using the RILEM model which predicts early age shrinkage. The model was modified to include the effects of aggregate type, environmental conditions and age. The change in load transfer at the joints and cracks, as indicated by relative vertical movement under dynamic loading as a result of temperature variation and humidity, is reported on. It was found that a change in load transfer occurred under increased loading and that this could be related to the crushing characteristics of the coarse aggregate. This paper presents the final outcome of the study in terms of theoretically based equations that were adjusted using regression techniques to fit the field experience. These equations have now been incorporated into a mechanistically-based design method for concrete pavements, cncPave.
Linear spectropolarimetry across the optical spectrum of Herbig Ae/Be stars

We present the results of spectropolarimetric observations of 12 Herbig Ae/Be objects. Our data have the largest spectropolarimetric wavelength coverage, 4560 A to 9480~A, published to date. A change in linear polarisation across the Hα line, is detected in all objects. Such a line effect reveals the fact that stellar photons are scattered off free electrons that are not distributed in a spherically symmetric volume, suggesting the presence of small disks around these accreting objects. Thanks to the large wavelength coverage, we can report that Hα is the spectral line in the optical wavelength range that is most sensitive to revealing deviations from spherical symmetry, and the one most likely to show a line effect across the polarisation in such cases. Few other spectral lines display changes in polarisation across the line. In addition, Hα is the only line which shows an effect across its absorption component in some sources. We present a scenario explaining this finding and demonstrate that the detection of the line effect strongly relies on the number of photons scattered into our line of sight. We highlight the special case of R Mon, which is the only object in our sample to show many lines with a polarisation effect, which is much stronger than in all other objects. Given that the object and its nebulosity is spatially resolved, we argue that this is due to scattering of the stellar and emission spectrum off circumstellar dust.
Polarization transfer in proton Compton scattering at high momentum transfer

The Jefferson Lab Hall A experiment E99-114 comprised a series of measurements to explore proton Compton scattering at high momentum transfer. For the first time, the polarisation transfer observables in the p (~ 0 ~ p) reaction were measured in the GeV energy range, where it is believed that quark-gluon degrees of freedom begin to dominate. The experiment utilised a circularly polarised photon beam incident on a liquid hydrogen target, with the scattered photon and recoil proton detected in a lead-glass calorimeter and a magnetic spectrometer, respectively.
Influence of humorous leadership at workplace on the innovative behavior of leaders and their leadership effectiveness

The influence of humor on interpersonal relationship and behavior has been attracting increasing attention from various enterprises. Participants in this study were Taiwan’s corporate leaders and the influence of their styles of humor on innovative behavior and leadership effectiveness was examined. The study results showed that self-enhancing humor played a key role in leadership at work place. It not only enhanced leaders’ innovative behavior but leadership effectiveness. On the other hand, aggressive humor showed a negative but small effect on leadership effectiveness. The results may serve as the criteria in the selection of prospective department heads/officials and facilitate the development of self-enhancing humor in various trainings. Key words: Humorous leadership, humor style, innovative behavior, leadership effectiveness.
Detection of HC3N Maser Emission in NGC 253

We report the detection of maser emission from the transition of at 36.4 GHz toward the nearby starburst galaxy NGC 253. This is the first detection of maser emission from this transition in either a Galactic or extragalactic source. The maser emission has a brightness temperature in excess of 2500 K and is offset from the center of the galaxy by approximately 18″ (300 pc), but close to a previously reported class I methanol maser. Both the and methanol masers appear to arise near the interface between the galactic bar and the central molecular zone, where it is thought that molecular gas is being transported inwards, producing a region of extensive low-velocity shocks.
Measurement of thermal transport properties for molten silicate glasses at high temperatures by means of a novel laser flash technique

Thermal transport propertics; effusivity, diffusivity and conductivity, of six silicate glasses in the molten state have been determined in the temperature range between 1073 and 1673 K. The glass sample was melted in a platinum crucible and heated to the desired temperature. Then, a single laser pulse was flashed on the bottom surface of the platinum crucible, and the infrared ray irradiated from the same bottom surface was measured for obtaining the temperature decay from which thermal effusivity of the sample could be estimated in the molten state. Thermal diffusivity and thermal conductivity were also estimated with available values of specific heat capacity and density of the glasses. Thermal transport properties of six glasses were found to slightly depend on temperature.
Self-Assembly and Hydrogelation of Peptide Amphiphiles

Seven peptide amphiphiles were successfully synthesized using solid phase peptide synthesis method. Peptide amphiphiles were characterized using Matrix-assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometer (MALDI-TOF MS). Atomic force microscopy (AFM) study showed that peptide amphiphiles having glycine, valine, or proline as linker, self-assembled into 100-200 nm nanofibers structure. According to our research, both peptide amphiphile with positive and negative charges bear similar self-assembly properties. Peptide amphiphile also showed its capability as low molecular weight gelator (LMWG). Peptide amphiphiles bearing C-16 and C-12 as alkyl showed better hydrogelation properties than C-8 alkyl. Five out of seven peptide amphiphiles have minimum gelation concentration (MGC) lower than 1% (w/v).
