Effect of mycorrhization on the growth of plantain seedlings in substrate with and without the presence of plant parasitic nematodes

We compared the effect of pre-inoculation with the following arbuscular mycorrhizal fungi (AMF), on the growth of vegetative propagules (suckers) of plantain (Musa AAB): 1) Glomus fistulosum, 2) Glomus fasciculatum, and 3) commercial inoculum (mixture of G. aggregatum, G. fistulosum, G.manihotis, G. fasciculatum, Kuklosplora colombiana and Scutellospora spp.), compared with a control without AMF, in substrate with and without the presence of Radopholus similis and Helicotylenchus spp. Furthermore, we evaluated the effect of AMF on the final amount of plant parasitic nematodes in roots and rhizosphere soil. The results indicated a significant intensification in the mycorrhizal colonization in roots inoculated with commercial inoculum of AMF (40 41%) compared with control and other AMFs (<3%). There were over 30% of increase in fresh weight of roots and dry matter (corm and air tissue) variables, in plants inoculated with commercial AMF, even in the presence of plant parasitic nematodes. The final amount of plant parasitic nematodes was not affected by the inoculation of AMF. We conclude that mycorrhizal fungi species’ mixture, present within the AMF commercial inoculum, stimulated root growth and nutrient uptake, thereby improving biomass production and offsetting the damage by plant parasitic nematodes.
Design of a dual-polarized phased array with self-grounded bowtie antenna

Phased Array antennas are one of the key components of the system design in the 5G wireless technology. They have many attractive benefits to offer in Sub-6 GHz for MIMO technology. The main benefit is their ability to directionally steer the main beam with the help of the electronic phase shifters without mechanically re-positioning the individual antennas. In this report the design, optimization and simulation results of a dual-polarized phased-array self-grounded bowtie antenna is discussed. A detailed literature study has been performed on the basic concepts of antenna. Moreover, published papers for the self-grounded bowtie antenna have been analysed for a deeper understanding of the working principles of the selfgrounded bowtie antenna. Different modelling techniques were studied and applied on the design of the single element to achieve the desired performance. A compact wide-band, 4 by 4 dual-polarized phased-array self-grounded bowtie antenna has been designed and analyzed for the bandwidth of 3.1-4.8 GHz, with the aim to manufacture a prototype. For broadside direction, the array has a directivity of 14.3-17.8 dBi and a reflection co-efficient better than -15 dB for the entire bandwidth. For scanning up to ±30°, the elements in the middle of the array have reflection co-efficient better than -10 dB for the bandwidth of 3.1-4.7 GHz in both E-and H-plane. For scanning up to ±45° the middle elements have reflection co-efficient better than -10 dB for the bandwidth 3.1-4 GHz in E-plane and in Hplane. Almost all elements have reflection coefficient better than -8 dB for the bandwidth 3.33. 6 GHz. For scanning up to ±60°, almost all elements have a reflection co-efficient better than -8dB for the frequency band 3.23. 5 GHz in E-plane and only the corner elements (elements:1, 13, 16 and 4) had a reflection co-efficient better than -8dB for a frequency band of 3.36-4.85 GHz in H-plane. The grating lobes appear only when scanning for ±60 ° for frequencies higher than 4.2 GHz. In conclusion, the array has a good performance for main beam steering up to ±45°. A prototype is under the process to be manufactured to show promising performance and a potential place in the market for wideband phased array antennas.

Comparison of Correlation, Partial Correlation, and Conditional Mutual Information for Interaction Effects Screening in Generalized Linear Models

Numerous screening techniques have been developed in recent years for genome-wide association studies (GWASs) (Moore et al., 2010). In this thesis, a novel model-free screening method was developed and validated by an extensive simulation study. Many screening methods were mainly focused on main effects, while very few studies considered the models containing both main effects and interaction effects. In this work, the interaction effects were fully considered and three different methods (Pearson’s Correlation Coefficient, Partial Correlation, and Conditional Mutual Information) were tested and their prediction accuracies were compared. Pearson’s Correlation Coefficient method, which is a direct interaction screening (DIS) procedure, tended to incorrectly screen interaction terms as it omits the relationship between main effects and interaction effects. To this end, we proposed to use two new interaction screening procedures, namely Partial Correlation Interaction Screening (PCIS) method and Conditional Mutual Information Interaction Screening (CMIIS) method. The Partial Correlation (PC) could measure association between two variables, while adjusting the effect of one or more extra variables. The Conditional Mutual Information (CMI) is the expected value of the mutual information (MI) of two random variables given the value of a third (Wyner, 1978), while MI is a measure of general dependence. Finally, an illustration and performance comparison of the three screening procedures by simulation studies were made and these procedures were applied
Reduction of Delay and Power by Using MLDD Technique in Error Correction

This project presents an error-detection method for Euclidean Geometry Low Density Parity Check codes with majority logic decoding methodology . The algorithm is synthesized in Xilinx 12.1 and simulated using Modelsim 5.7g . Majority logic decodable codes are suitable for memory applications due to their capability to correct a large number of errors. However, they require a large decoding time that impacts memory performance. The proposed fault-detection method significantly reduces the delay time by detecting the errors in parallel and in pipelining manner. Also the memory access time reduces when there is no error in the data read. The technique uses the majority logic decoder itself to detect failures, which makes the area overhead minimal and keeps the extra power consumption low. Starting from the original design of the ML decoder introduced, the proposed ML Detector/Decoder (MLDD) has been implemented.
Do CEOs' Personal Values Affect Employees' Innovative Work Behavior? Opening Up the 'Black Box' of Upper Echelons Theory

The majority of empirical studies focusing on Upper echelons theory have used top managers’ demographical characteristics as proxies for their personal characteristics and values, in order to investigate their influences on organizational outcomes. The aim of the present study was to directly measure the effects of CEOs’ personal value preferences (openness to change, conservation, and self-enhancement) on their employees’ innovative work behavior. The moderating effect of authentic leadership on these relationships was also investigated. Participants were 18 CEOs and 141 employees of small and medium-sized enterprises in the Netherlands. CEOs participated in preliminary interviews on the topic of innovation and, subsequently, indicated their value preferences in an online questionnaire, while employees responded to questions about their innovative work behavior and rated the degree to which they viewed their CEO to be authentic. Hierarchical linear modeling indicated that CEOs’ openness to change was positively related to their employees’ innovative work behavior, while CEOs’ self-enhancement was negatively related to it. CEOs’ conservation was not a significant predictor of employees’ innovative work behavior. Similarly, the moderating effect of authentic leadership was not confirmed in any of the hypothesized relationships. The results support the view that CEOs’ personal values influence organizational outcomes and stress the need to direct more attention to investigating the not readily available characteristics of top managers instead of using proxies.

In this article we study the digitally quasi comultiplications on the digital wedge products of pointed digital images. Especially, after defining a digitally quasi co-H-space and a digital Whitehead product, we calculate the cardinal number of the set of digital homotopy classes based on digitally quasi comultiplications of the wedge products of pointed digital images, and construct a digitally quasi co-H-space as a digital retract of a given digital image.
Asian Seafarers' Perceptions of Maritime Security Implementation in the Container Shipping Context

Maritime security is an important issue in the shipping industry. The international maritime organization (IMO) developed a Code of International Ship and Port Facility Security (ISPS Code) to enhance maritime security against piracy, terrorism, and any other illegal actions. Questionnaires are used to elicit Asian seafarers, perceptions of maritime security in the container shipping context. Exploratory factor analysis and confirmatory factor analysis techniques are applied to analyze the data obtained there from in order to understand the effect of maritime security implementation onboard ship. Four primary dimensions of maritime security implementation were identified, namely: security knowledge and capability, security manpower, security training, and security equipment. Results revealed that respondents from Philippines had high perceptions on security knowledge and capability, security manpower, and security equipment dimensions, whereas respondents from India and Myanmar had high perceptions on security training dimension. Theoretical and practical implications from the research findings in maritime security management are discussed.

Rickettsia spp. and its Effects on the Physiology and Behaviour of Dermacentor Variabilis

The genus Rickettsia is home to a number of species of endobacteria that infect vertebrates as well as invertebrates, some of these species being pathogenic. Rickettsia bacteria are transmitted to mammals by Dermacentor variabilis ticks in North America, but while pathogenic effects in mammals have been well described, the effect of the bacteria in ticks is less well explored. Experiments were performed to determine how the physiology and behaviour of the Dermacentor variabilis (Say) (Arachnida: Ixodidae) are affected by infection with Rickettsia bacteria. DNA analysis was used to determine the presence of Rickettsia genus in ticks. The supercooling point (SCP), fat content, and temperature preference were compared between infected and uninfected ticks. Infection incidence with Rickettsia spp . was 45.8% in males, 46.4% in unengorged females and 48.3 % in engorged females. Eggs were more resistant to freezing, followed by larvae, then adult ticks. There was no change in the temperature preference between males vs . engorged females, and females vs . engorged females. The presence of Rickettsia spp. did not significantly affect supercooling point, fat content and water content. However, there was a difference between infected and uninfected females, both engorged and unengorged, in temperature preference. We conclude that in both, engorged and unengorged female ticks, Rickettsia bacteria affect their behaviour but not physiology.
Re-examining the revival of online group buying mechanisms

In commercial environments consumers with limited order size can aggregate their demand through a group buying mechanism allowing them to enjoy the benefits of a wholesale deal. In electronic commerce, group buying was first introduced in the late 90s. Researchers in various fields conducted studies showing the business viability of the group buying model and it was even regarded as the shopping method for the 21st century. However, web-based group buying did not live up to its initial expectations and experienced an early fall down. In this paper, we provide an evaluation of some of the work carried out on group buying and an analysis of the group buying business model. Moreover, we examine a number of important trends in e-Commerce from a group buying perspective. Based on this analysis, we derive a set of conclusions regarding the re-introduction of the group buying model to the electronic marketplace. Key words: Electronic commerce, group buying, customer coalition formation, group management, demand aggregation mechanisms
FINDING CONNECTION BETWEEN EXTENSIVE READING AND STORY WRITING

This paper is aimed to investigate students’ vocabulary size before and after the extensive reading program and to explore whether there is a connection of extensive reading program and writing activities using Cartoon Story Maker. There were 17 students participating in this study. Data were collected from pre-test, post-test, observations, focus group discussions, and interviews. Findings show that students’ vocabulary level rises by averagely 1.135 words. Students’ perception on reading activities and their reading preferences change. More interestingly, the extensive reading program has given them joyful reading experiences and encouraged them to read more. Reading logbooks function as scaffolding for vocabulary learning and sentence structure awareness. In addition, Cartoon Story Maker is perceived as the tool to develop imagination into stories built up from their previous reading experiences. This study indicates that there is a connection between reading and writing through several aspects that establish reading and writing skills. The cartoon stories are inspired by the stories they read, the vocabulary they learned, the retold plots, and there is an artful blend of imagination and creativity.
Chronic Disease and Mental Health Perception

The sociodemographic characteristics of individuals with chronic disease(s) and the presence of impaired mental health need further attention as indicated by WHO. This is particularly relevant in primary settings and for specific populations as those with an ageing condition. The purpose of this study was to examine the self-assessed perceptions of mental health status of participants who visited a Health Centre. A quantitative study was conducted. A purposive sample (n=1336) of users attending a Portuguese Health Centre were asked to complete a series of questionnaires. One on socio-demographic information, one on the presence of chronic disease(s), one on self-perception of wellbeing, plus Goldberg’s (1979) General Health Questionnaire (GHQ-28). Data was analyzed using the Statistical Package for Social Sciences (SPSS V20). Multiple analyses were conducted. Of the 1336 participants, 63.5 % were female. The average age of the total sample was 52 (sd: 17.77) and 929 presented with 1 or more chronic illnesses (mean: 1.47 in women and 1.34 for men). The variables associated with a greater likelihood of self-reported mental health and chronic disease were female gender (63%), recurring visits (4 or more) to their GP during the past year (48.4%) and presence of 2 or more chronic diseases. Inferential analysis showed a statistically significant association with the GHQ-28 scores. The study findings suggest that chronic diseases and mental health self-perception appear to be associated. Better strategies to facilitate early identification of compromised mental health in chronic patients should be implemented. Further research on this topic is suggested.
OGLE-2013-BLG-1761Lb: A Massive Planet around an M/K Dwarf

We report the discovery and the analysis of the planetary microlensing event, OGLE-2013-BLG-1761. There are some degenerate solutions in this event because the planetary anomaly is only sparsely sampled. However, the detailed light-curve analysis ruled out all stellar binary models and shows the lens to be a planetary system. There is the so-called close/wide degeneracy in the solutions with the planet/host mass ratio of q ∼ (7.0 ± 2.0) × 10−3 and q ∼ (8.1 ± 2.6) × 10−3 with the projected separation in Einstein radius units of s = 0.95 (close) and s = 1.18 (wide), respectively. The microlens parallax effect is not detected, but the finite source effect is detected. Our Bayesian analysis indicates that the lens system is located away from us and the host star is an M/K dwarf with a mass of orbited by a super-Jupiter mass planet with a mass of at the projected separation of . The preference of the large lens distance in the Bayesian analysis is due to the relatively large observed source star radius. The distance and other physical parameters may be constrained by the future high-resolution imaging by large ground telescopes or HST. If the estimated lens distance is correct, then this planet provides another sample for testing the claimed deficit of planets in the Galactic bulge.
Implementation and application of orientation correction on SIFT and SURF matching

Post-processing after matching technique such as RANSAC is useful for reducing outliners. However, such methods may not be able to increase the number of correctly matched pairs that is important in some application such as image stitching. In this work, a post-processing technique for increasing the number of correct matched points between two images with on-plane rotation is proposed. The proposed method makes use of the dominant rotational degree between two corresponding images to increase the number of matched points after feature extraction process using state-of-the-art methods such as Scale Invariant Feature Transform (SIFT) or Speeded-Up Robust Feature (SURF). The proposed method can generally increase the number of matched points around 10% to 20%. Furthermore, it can also correct the false matching which is caused by similar appearance of features.
Living in the shadow of shame and stigma: Lived experience of mothers withdeaf children

Congenital deafness is one of the most common childhood disorders and every year many children are born with permanent hearing loss. The present study was carried out to understand the experience of mothers with deaf children. This study was conducted with a qualitative approach. The participants were 35 mothers of children with congenital deafness who were selected by purposive sampling. The data was collected through semi-structured indepth interviews and analyzed using thematic analysis introduced by Braun and Clarke. Data analysis revealed 3 themes and 9 sub-themes including social stigma (prying eyes, pity aversion, feeling of discrimination, taunt from people), internalized stigma (feeling of inferiority, feeling of shame and embarrassment), and reaction to stigma (turning to concealment, cautious disclosure, and marginalization). Shame and stigma were the major experiences of Iranian mothers of deaf children that shadowed their lives. These experiences lead mainly to ineffective coping mechanisms such as avoidance of using hearing aids and concealment of the child’s hearing loss. In addition, to cope with perceived stigma, mothers isolate and marginalize themselves and pursue secrecy strategies. Therefore, our findings are important for health professionals who are working with families having children with hearing loss. They need to aware of the problems faced by the families and should advocate necessary support.

Biophsyical constraints on gross primary production by the terrestrial biosphere

Persistent divergences among the predictions of complex carbon-cycle models include differences in the sign as well as the magnitude of the response of global terrestrial primary production to climate change. Such problems with current models indicate an urgent need to reassess the principles underlying the environmental controls of primary production. The global patterns of annual and maximum monthly terrestrial gross primary production (GPP) by C 3 plants are explored here using a simple first-principles model based on the light-use efficiency formalism and the Farquhar model for C 3 photosynthesis. The model is driven by incident photosynthetically active radiation (PAR) and remotely sensed green-vegetation cover, with additional constraints imposed by low-temperature inhibition and CO 2 limitation. The ratio of leaf-internal to ambient CO 2 concentration in the model responds to growing-season mean temperature, atmospheric dryness (indexed by the cumulative water deficit, Δ E ) and elevation, based on an optimality theory. The greatest annual GPP is predicted for tropical moist forests, but the maximum (summer) monthly GPP can be as high, or higher, in boreal or temperate forests. These findings are supported by a new analysis of CO 2 flux measurements. The explanation is simply based on the seasonal and latitudinal distribution of PAR combined with the physiology of photosynthesis. By successively imposing biophysical constraints, it is shown that partial vegetation cover – driven primarily by water shortage – represents the largest constraint on global GPP.
