Exploring the functional role of the bacterial protein SeqA and co--?occurring genome stability systems in TnsE--?mediated Tn7 transposition using the E. coli model system

Transposon Tn7, is unique among transposons for both its target specificity and selectivity. One of its target selection pathways, mediated by the protein TnsE, has been found to allow Tn7 to preferentially transpose into mobile plasmids despite there only composing approximately 1% of the bacterial genome. Prior research in the Peters laboratory revealed both a physical interaction between TnsE and the bacterial protein SeqA as well as a functional role of the TnsE-SeqA interaction in TnsE-mediated transposition. Based on this work a model was developed, whereby SeqA occludes TnsE’s access to the replicating chromosome. An unrelated study from another group found that the genesyfbV, met], holD, mutH, and matP co-occurred with seqA in genomes with an ancestral dam gene. In this project, an in vivo Tn7 transposition assay was used to investigate the role of the SeqA-TnsE interaction in the TnsE pathway of Tn7 transposition. The same transposition assay was also used on the co-occuring set of bacterial proteins in order to identify a possible association with their gene products and TnsE-mediated transposition. The Tn7 transposition events were then mapped using two complementary assays. The results suggest that in the absence of SeqA, TnsE-mediated Tn7 transposition increases significantly and that a much higher percentage of the insertions occur into the chromosome in a AseqA background, thus supporting our model. The results for the other proteins were much less clear, with the only significant change in TnsE-mediated transposition frequency occurring in the AmetJ mutant, where no successful Tn7 transpositions were observed within the detection of our assay.
Gauge theory and knot homologies

Topological gauge theories in four dimensions which admit surface operators provide a natural framework for realizing homological knot invariants. Every such theory leads to an action of the braid group on branes on the corresponding moduli space. This action plays a key role in the construction of homological knot invariants. We illustrate the general construction with a simple example based on surface operators in 𝒩 = 4 twisted gauge theory which lead to a categorification of a variant of the Casson invariant.
Comparison of High-Power DC-DC Converters for Solar Applications with Respect to Efficiency and Chip-area

This thesis is intended to analyze and compare the efficiency of the conventional 2L-DAB with the so-called Multi-Level DAB (ML-DAB) and three-Level DAB (3LDAB) for the solar applications. The latter features from the three-level legs both on the LV and the MV sides; while, the former is a combination of the 2L-legs on the LV side bridge and the NPC legs on the MV side bridge. The converters are rated for 1MW power with the LVDC-link and the MVDC-link voltages of 1.3kV and 16kV respectively. The SiC MOSFETs are utilized as the power switches to ensure low switching losses in high switching frequencies. The semiconductor chip-area based comparison algorithm is applied to have a fair comparison between the topologies. The definition of average efficiency for the European solar mix is employed to make the comparison specific to the solar applications. The switching frequency of the converters is swept from 10kHz to 80kHz to investigate its effect on the performance of the converters. The chip-area of the MOSFETs are also varied to explore the efficiency variations with the chip-area change and therefore, the semiconductor costs. It has been shown that for the specified modulation parameters and the same operating junction temperature , the 2L-DAB has higher full-load efficiency while, it requires lower chip-area than the ML-DAB for all switching frequency ranges. It has also been demonstrated that for the same amount of investment on the semiconductors, the 2L-DAB can achieve a higher efficiency and a lower operating temperature for the MOSFETs compared to the ML-DAB. It was also shown that by less than 70% increase in the required chip-area, the full-load efficiency and the average efficiency for European solar mix of all converters can increase more than 2% and 0.7% respectively for all switching frequency ranges.
Calorimetric measurement of work in a quantum system

We propose a calorimetric measurement of work in a quantum system. As a physical realization, we consider a superconducting two-level system, a Cooper-pair box, driven by a gate voltage past an avoided level crossing at charge degeneracy. We demonstrate that, with realistic experimental parameters, the temperature measurement of a resistor (environment) can detect single microwave photons emitted or absorbed by the two-level system. This method would thus be a way to measure the full distribution of work in repeated measurements, and to assess the quantum fluctuation relations.
Ion-beam and plasma etching of a conical-pores photonic crystal for thin-film solar cell

Conical holes bored in the active layer of a thin-film silicon solar cell by ion-beam lithography (IBL) show increase of effective optical absorption in the underlying silicon active layer. The optical properties are numerically simulated by the 3D finite-difference time-domain method (3D-FDTD), showing wideband increase of the UV, visible, and IR quantum efficiency. An experimental fabrication procedure is developed using IBL for high wide- area repeatability. A further optimization on the cone shapes is performed in order to make fabrication feasible with plasma etching techniques.
REPEATED CAPTURE OF BEACH MICE (PEROMYSCUS POLIONOTUS PHASMA AND P. P. NIVEIVENTRIS) REDUCES BODY MASS

Abstract Body mass is commonly used as an indicator of habitat quality and body condition in small-mammal populations. We examined the effects of consecutive days of livetrapping on body mass of 2 federally listed subspecies of beach mice on the eastern coast of Florida: the Anastasia Island beach mouse (Peromyscus polionotus phasma) and the southeastern beach mouse (P. p. niveiventris). Mean mass loss (approximately 0.5 g/recaptured day) was additive and occurred for Anastasia Island beach mice over 2 consecutive days and for southeastern beach mice over 3 consecutive days. Researchers should exercise caution when their trapping protocols call for consecutive nights of trapping.
AN IMPROVED MODEL-BASED OBSERVER FOR INERTIAL NAVIGATION FOR QUADROTORS WITH LOW COST IMUS BY DAVID HANLEY

In this thesis, we present a model-based observer for inertial navigation of quadrotors and other multirotor aircraft. We include in our model a Coriolis term that has been neglected in prior work. Doing so allows us to estimate the entire velocity vector in the quadrotor’s frame of reference—including along the z-axis of this frame—with data only from a low-cost inertial measurement unit (IMU), something that has not been demonstrated previously. An observability analysis predicts that our proposed observer will perform well. Experimental results over 110 flight trials verify this prediction, showing that our proposed observer achieves lower root mean square error than three other state-of-the-art model-based observers.
ISSN : 2319-6505 GENETIC ANALYSIS AND QTL MAPPING OF AGRO-MORPHOLOGICAL TRAITS IN LOWLAND RICE ( ORYZA SATIVA L . ) UNDER DROUGHT CONDITIONS

The present study was undertaken to evaluate lowland rice genetic variability associated with agro-morphological traits under drought condition. A set of 250 recombinant inbred lines (RILs) from the cross between rice parental cultivarIR64 (sensitive to drought) and ITA112 (tolerant to drought) were used. The experiment was performed at Banfora in Burkina Faso using randomized complete block design with 2 replications. High genetic variability was observed for all studied traits. Moderate to high heritability in broad sense were observed for almost studied traits. Grain yield recorded positive correlation with all traits except day to 80% maturity and number of tillers. Using inclusive composite interval mapping software (ICIM), a total of 7 QTLs were identified for this study distributed on 5 chromosomes (2; 3; 4; 5; 6) and associated with day to 50% heading (QTL50DH), day to 80%maturity (QTL80DM), Biomass (QTLBiom), flag leaf width (QTLFLW), plant height (QTLPH), panicle length (QTLPL) and percentage of fertile spikelet (QTLPFS). The percentage of phenotypic variance (PVE) explained by QTLs ranged from 5.45 to 14.58%. QTL50DH, QTL80DM and QTLBiom were overlapped in same region on chromosome 3, which was in accordance with correlation results among the traits.
Trait Anxiety in Young Athletes as a Function of Parental Pressure and Motivational Climate: Is Parental Pressure Always Harmful?

We assessed the role of parental behaviors on sport performance anxiety. Measures of trait anxiety, parental pressure, and parent-initiated motivational climate were administered to youth swimmers throughout the season. High parental pressure within either a low mastery or a high ego motivational climate was associated with the highest levels of anxiety at all time points. An early-season, high-pressure/low-mastery combination was also associated with relative increases in anxiety over the season, whereas high pressure within a high mastery climate was associated with relative decreases. Results indicate that parental pressure can have differential effects depending upon motivational climate.

Design and Simulation of NFC-Based M2M Payment Model for Mobile Phone With Trusted Platform Module

The introduction of the information technology (IT) plus the introduction of the internet, has been said to be the source of advancement in electronic commerce. It’s focused on that, in the future, predictably, the society will be cashless, the circulation of physical cash will have decreased. The use of IT especially in the finance and industrial sector, not forgetting the proliferation of ecommerce hasled to increased speed in arising of electronic cash. The use of cashless methods, is appealing to the younger people. This is the reason why machine to machine (M2M) is gaining momentum as days go by. Some countries like Korea, implementation of cashless money methods, the electronic cash has been on a steady rise since 2000. A good example is the T-Money transport card. This is prepaid or postpaid electronic cash. It is very popular transportation card, which is widely used throughout most parts of Korea. In the future, its use will most likely to be expanded if it becomes integrated T-Money. The postpaid T-Money is a good example of M2M implementation, in which users now don’t need to carry cash to travel. They can transfer the money from mobile phones to the billing systems in the transport vehicles seamlessly. The transport card has developed into a mobile payment system in recent years and has become increasingly popular in Korea. This research paper, will focus on the design and simulation of machine to machine using NFC-based payment model. This will mainly target smartphone applications, which are more popular nowadays, not only amongst the youth but all generations.
Introduction of the Ponto-Caspian Bloody-red Mysid Hemimysis anomala into the Lake Michigan Basin

ABSTRACT Hemimysis anomala G.O. Sars, 1907, a mysid species native to the Ponto-Caspian region, was discovered during fall 2006 in the Lake Michigan basin. Large numbers of individuals formed aggregations (averaging 1,540 ± 333 individuals/m2) in a shallow docking basin connected to the channel linking Lake Michigan and Muskegon Lake. The population included females (63%), males (35%), and juveniles (2%). The global invasion pattern in H. anomala is similar to that in another Ponto-Caspian peracarid crustacean, Echinogammarus ischnus. As with E. ischnus, the expansion of H. anomala in North America is anticipated.

First a two stage adsorption process for the separation of the catechins was designed. Secondly a spray drying process is modeled to determine the equipment and the operational conditions, as well as the economic potential. The conceptual study shows that it is possible to obtain a powder of catechins with 83.5 % purity and a particle sauter mean diameter of 7.48 μm.
Leadership Strategies for Embedding Sustainability and Resilience in Organizations with an Emphasis on Sustainable Energy

Embedding sustainability in an organization is often linked to effective leadership. By design, changes in leadership within the organization may lead to changes in commitment or perceived importance of sustainability in organizations. While some leaders in organizations are interested in embedding sustainability within an organizational structure, other leaders believe in putting their own stamp on sustainability efforts. Using a mixed methodology approach to interviews and literature review, to confirm or dispel the underscored notion of the importance of leadership play in embedding sustainability within city organization. The research inquiry includes in-person interviews with top city staff and elected officials in a large Midwestern city, and a review of the internal documents and reports from the past 5 years, to examine the role that elected and appointed officials have in embedding sustainability within cities, and whether a change in leadership may have an impact on continuity of sustainability implementation and long term viability of such policies. The paper focuses on the implementation of sustainable energy policies within a municipal organizational structure as a mean of constructing a better understanding of leadership on sustainability implementation and embedment. While the further inquiry is needed, the research points out that an active partnership between city managers, administrators, and elected officials must be in place to support integrating sustainability from within and that sustainability thrives where exhaustive leadership support such initiatives and efforts.
Characterizing Interactions between Suwannee River Dissolved Organic Matter and Cu(II) Using Fluorescence ExcitationEmission Matrices and Parallel Factor Analysis

This study investigated the binding of Cu(II) to di ssolved organic matter (DOM) using the method of fluorescence excitationemission matrix (EEM) combined with para llel factor analysis (PARAFAC). The examined DOM samples included Suwannee River natural organic matter (SRNOM), humic acid (SRHA), fulvic acid (SRFA) and hydrophilic acid (SRHPiA). The differences in metal b inding properties were discerned via the behavior o f individual groups of DOM fluorophores. PARAFAC examination showed that there were up to seven independent EEM components that behave differently in terms of the eff ects of Cu(II) on their fluorescence intensity. Comp onent 1 (λex /λem = (270, 340, 395) nm /~500 nm) and Component 2 (λex /λem = (~240, 330) nm /~450 nm) were found to be responsive to Cu(II) binding in all four DOM samples. Component 3 ( λex /λem = (220, 270-310) nm/400 nm) was present in the case of Cu(II) binding to SRNOM, SRFA, and SRHPiA. Component 4 ( λex /λem = (260, 340) nm /470 nm), Component 5 (λex /λem = (220, 245, 280) nm /420 nm), and Component 6 ( λex /λem = (220, 260, 340) nm /420 nm) were found in Cu(II) binding to SRNOM and SRHA, while Component 7 ( λex /λem = (220, 260-340) nm/430 nm) emerged as a result of in Cu(II) binding to SRFA and SRHPiA. The apparent equilibrium constants of Cu(II) binding t o each PARAFAC-discerned component were determined using the Ryan and Weber equation, and the corresponding log K values were in the range of 4.9-6.1 while the perce ntage of fluorescence intensity ( f)that was quenched by Cu(II) was in the range of 0.45-0.99 for different DOM components discerned by PARAFAC. The results demonstrate that PARAFAC analysis of metals affecting on DOM EEM is a promising approach to gain better insight into th e interactions between trace metals and specific groups of DOM fluorophores.

BUCKLING OF FUNCTIONALLY GRADED BEAMS WITH RECTANGULAR AND ANNULAR SECTIONS SUBJECTED TO AXIAL COMPRESSION

The current study presents a new analytical method for buckling analysis of rectangular and annular beams made up of functionally graded materials with constant thickness and Poisson’s ratio. The boundary conditions of the beam are assumed to be simply supported and clamped. The stability equations were obtained by using conservation of energy. The critical buckling load and first mode shape were obtained using Variational Calculus method. Increasing in buckling capacity and improvement in the behavior of functionally graded beams in comparison to homogenous beams have been investigated. After simplifying results, Duffing differential equation for homogeneous beam without oscillations was obtained and validity of this new work was proved.
Analysis of the value that open source contributes to business models

In the constantly turbulent and dynamic environments in which businesses today function, one has to be able to adapt and change one's overall strategy in order to remain competitive. Business models, when carefully constructed can be a valuable tool for firms. In addition to focussing a firm's activities on crucial areas from which they gain the most value, they play an important role in innovation. Innovation is the key to competitiveness and growth. The phenomenon of open source software(OSS) is gaining momentum and attracting much interest in the business world. Firms can take advantage of this situation by combining the power of business models with the opportunities surrounding OSS. In this paper we develop a business model framework to analyse the different OSS strategies available and provide clarity around these concepts.
Country-of-origin effects in industrial goods markets: Do country-of-origin image effects differ for different buying center members?

Most of the past findings regarding COO (country-of-origin) effects refer to consumer decision-making. While their purchase decisions are taken by the consumers themselves individually, industrial purchases are mostly conducted by organizational buying centers. This raises the question if and to what extent the impact of COO effects varies between the different members of a buying center – an issue unaddressed in research so far. Based on construal level theory we answer this question by applying a multiple mediation analysis to the empirical data, which we collected through interviews at a truck trade show. Main findings confirm the general relevance of COO effects for the purchase decision making for these industrial goods. However, the significance of this COO effect was found to be of lesser importance for product users than for non-users. On the basis of our findings, practitioners can achieve higher marketing impact through the differentiation of their marketing activities.
Conceptions of Oral English Teaching: A Case Study of Teacher Cognition on Oral English Teaching and Classroom Practice

Abstract This paper reports a case study investigating and comparing the cognition and classroom practice of two college English teachers with regards to oral English teaching in an agricultural university. Both consistency and inconsistency between their cognition and practice are examined and reasons especially for inconsistency are explored. Findings suggest that teachers do hold a system of cognition which shapes their classroom practice to a very large extent. However, due to the influence of many other factors, both internal and external, their practice in oral English teaching does not always reflect their cognition. 本文对某农业(省属)大学两位大学英语教师对口语教学的认知及其课堂行为进行了个 案研究，探索大学英语教师对口语教学的认知状况，及其与实际课堂教学的关系。 重在探 讨教师认知与课堂行为的一致或不一致之处，尤其探讨了导致两者不一致的因素。 结果 表明，教师有一套复杂的认知系统，教师认知在很大程度上影响了教师的实际课堂教学行 为，但是，受其他内外因素的影响，教师课堂教学行为也出现了与教师认知不一致之处。
