The Dimensions of Professional Development Needs for Secondary Agricultural Education Teachers Across Career Stages: A Multiple Case Study Comparison

This study sought to understand the professional development needs articulated by secondary agricultural education teachers across three career stages. To accomplish this, we collected data from secondary agricultural educators (N = 66) in Louisiana. Then, we performed a cross-case analysis to compare and contrast themes and axial codes. Through our analysis, three themes emerged in each case: (1) presage variables, (2) context variables, and (3) process variables. The themes represented the various dimensions of professional development that teachers expressed they desired to facilitate student success better. In particular, the Early Career Teachers’ non-traditional backgrounds often limited their exposure to opportunities; therefore, they desired more knowledge and skills in technical agricultural concepts. Meanwhile, Mid-Career Teachers were more stable and confident in their roles as secondary agricultural education teachers; nevertheless, they were frustrated because of various contextual forces that complicated their job duties. Finally, Career Teachers were experiencing career wind-down and had unique professional development requests to help them cope better with contextual changes influencing their responsibilities. Findings from this study, therefore, suggested that although areas of commonality exist across career stages, it is critical to differentiate professional development across programmatic dimensions of agricultural education.
Cartographic interpretation of the “meta” notion in the cultural heritage context

The monograph [Aslanikashvili, 1974] does not define the term “metacartography”, although the notion itself is described in sufficient detail to be understood. A. Aslanikashvili’s metacartography has proven to be very useful in considering the relations between modern systematic cartographic phenomena, which are often relate to Web 2.0 cartography. The article offers a practical interpretation of the “meta” notion in such phenomena as National Atlases, National Spatial Data Infrastructures and OpenStreetMap. This is done using the Conceptual Frameworks (CoFr) method and the Atlas Extender (AtEx), which allow extending atlases in the classical sense to extended atlas systems. AtEx implements a CoFr method of relational cartography based on patterns (hereinafter RelCa), among which are relational patterns of “meta”. CoFr describe the structure of spatial information systems in an extended sense, and relational cartographies are defined as the coordinated art, science and technology of making and using relations in (extended) cartographic systems and between (extended) cartographic systems. Due to this we can consider relational spaces that have a lot in common with the specific spaces of A. Aslanikashvili. To apply the RelCa methods, the understanding of “metacartography”, “map meta-model” and “map language” notions have been updated. For this purpose, Model-Based Engineering (MBE) has been used, an area of computer science that is evolving in our century. The analogies between BMI constructions, modern systematic cartographic phenomena and A. Aslanikashvili metacartography are shown. It has been proved abductively that in modern conditions the field of cartography research needs to be extended by relational spaces or to a system of spatial systems of a certain epistemological structure. Important in this structuring is the relation of “meta” that A. Aslanikashvili began to explore. The abduction proved the presence and necessity of using the “meta” relation when constructing cultural heritage maps. In particular, the interpretation of the “meta” relation for choropleth maps is proposed, modeling the saturation assessment of the country by the entities of the material cultural heritage. The results obtained will be included in the Atlas of Cultural Heritage of Ukraine.

Distance learners’ study-related interactions with other people in their life-contexts: investigating an unexplored phenomenon

Distance learners are typically embedded within rich and complex life-contexts that comprise family, friends, work colleagues, and community connections. However, relatively few studies explore the interplay between distance learners’ life-contexts and their studies and none examine the study-related interactions distance learners engage in with other people in their life-contexts. Changes currently occurring in the higher education sector, including the emergence of postgraduate lifelong learners, mean this position is becoming untenable. This research note provides an overview of a study currently under development that is intended to shed light on this unexplored phenomena.
FEATURES OF DEPRESSIVE DISORDER IN WOMAN 
DURING PREGNANCY

Purpose of the article is to show features of depressive disorder during pregnancy and how it can be different according to various personal indicators. Pregnancy and depression often go hand in hand. This condition affects about every tenth pregnant woman. According to recent research, sudden surges and changes in the hormonal background that accompany the entire pregnancy can really affect brain biochemistry, which in turn can lead to real clinical depression. The procedure of research registered at the women's consultation and obstetric ward and pathology department of pregnancy in Maternity hospital No. 3 (Kyiv). It lasted for 5 months. The group of pregnant women consisted of 100 people aged 18 to 42 years. Among them were 35 women in 1 trimester of pregnancy, 40 women in 2 trimester of pregnancy, 25 women in 3 trimester of pregnancy. To identify the presence and severity of depression among pregnant women, we used the following methods: Hamilton Depression Scale, Behterev Depression Questionnaire (female version). Anxiety and depression in women during pregnancy require early detection and correction due to their significant negative impact on pregnancy, childbirth, postpartum and further psychophysical development and social adaptation of children. Different indicators of age and trimester affect the level of expression of the depressive disorder. If woman had problems with conception or she was treated for infertility, the probability of her depression in her pregnancy increases by 10 times. Depression may be more likely to eclipse pregnancy and women who have suffered mental illness, anxiety, or depression before conception. This disorder may also occur in problematic relationships, as well as in situations where relatives have had a depression or mental illness, a woman has already had a miscarriage or her current pregnancy is a high-risk group. Depression during pregnancy has significant implications for pregnancy outcomes and maternal and child health. There is a need to identify which family, physical and mental health factors are associated with depression during pregnancy.
Area Equalization PWM Techniques for Single- Phase Full Bridge Inverter with Fluctuating DC Input

An extension of equal sampling technique (EST) based pulse width modulation (PWM) is presented for the single- phase inverter to reduce lower order harmonics caused by the fluctuating dc input. In the EST, which has been proposed earlier for constant dc, the width of PWM pulses is determined by making the area of the PWM signal equal to the area under the sampled reference waveform. The concept of equal area criterion equally applicable for fluctuating dc input with required modifications of the governing equations. Simulation results show that EST is triumphant in reducing lower order harmonics. Potential applications of the proposed technique are in fixed and variable frequency inverters for power supplies and ac motor drives which experience voltage ripple in the dc-link either when fed from a weak ac system or when insufficient filtering is employed.
Thermo-hygro-chemo-mechanical model of concrete at early ages and its extension to tumor growth numerical analysis

The aim of the PhD thesis is the development of two multiphase models from a common theoretical basis, applied to two very different research fields: i) the study of the behavior of concrete at early ages, essentially for the prevention of cracking and related issues; ii) the analysis of the physical, chemical and biological processes that govern the growth of cancer. The modeling of concrete at early ages is very important and useful for the design of durable and sustainable structures. The model developed during the PhD thesis has been implemented on the finite element code Cast3M and then validated via the simulation of experimental cases. Nowadays this model allows for several applications: study of stresses and cracking in young concrete, analysis of thermal and hygral gradients, predictions of autogenous and drying shrinkage, creep strain, stress redistribution, study of the inhibition of hydration caused by drying, study of repairs, etc. In the fight against cancer, the advance of medical strategies based on numerical analysis has a crucial scientific interest and can have a great social impact. The equations which govern the thermo-hygro-chemo-mechanical behavior of concrete at early ages have many formal analogies with those typically used to model tumor growth. Hence, these equations have been readapted and a novel mathematical model for tumor growth has been developed. This model has been implemented in Cast3M and the first numerical results are encouraging since qualitatively close to the experimental data present in the scientific bibliography.
New tests and test methodologies for scan cell internal faults

Semiconductor industry goals for the quality of shipped products continue to get higher to satisfy customer requirements. Higher quality of shipped electronic devices can only be obtained by thorough tests of the manufactured components. Scan chains are universally used in large industrial designs in order to cost effectively test manufactured electronic devices. They contain nearly half of the logic transistors in large industrial designs. Yet, faults in the scan cells are not directly targeted by the existing tests. The main objective of this thesis is to investigate the detectability of the faults internal to scan cells. In this thesis, we analyze the detection of line stuck-at, transistor stuck-on, resistive opens and bridging faults in scan cells. Both synchronous and asynchronous scan cells are considered. We define the notion of half-speed flush test and demonstrate that such new tests increase coverage of internal faults in scan cells. A new set of flush tests is proposed and such tests are applied at higher temperatures to detect scan cell internal opens with a wider range of resistances. We also propose new scan based tests to further increase the coverage of those opens. The proposed tests are shown to achieve the maximum possible coverage of opens in transistors internal to scan cells. For an asynchronous scan cell considered, two new flush tests are added to cover the faults that are not detected by the tests for synchronous scan cells. An analysis of detection of a set of scan cell internal bridging faults is described. Both zero-resistance and nonzeroresistance bridging fault models are considered. We show that the detection of some zeroresistance non-feedback bridging faults requires two-pattern tests. We classify the undetectable faults based on the reasons for their undetectability. We also propose an enhanced logic BIST architecture that accomplishes the new flush tests we propose to detect scan cell internal opens.
Large-Eddy simulation of physiological pulsatile non-Newtonian flow in a channel with double constriction

Physiological pulsatile flow in a 3D model of arterial double stenosis, using the modified Power-law blood viscosity model, is investigated by applying Large Eddy Simulation (LES) technique. The computational domain has been chosen is a simple channel with biological type stenoses. The physiological pulsation is generated at the inlet of the model using the first four harmonics of the Fourier series of the physiological pressure pulse. In LES, a top-hat spatial grid-filter is applied to the Navier-Stokes equations of motion to separate the large scale flows from the subgrid scale (SGS). The large scale flows are then resolved fully while the unresolved SGS motions are modelled using the localized dynamic model. The flow Reynolds numbers which are typical of those found in human large artery are chosen in the present work. Transitions to turbulent of the pulsatile non-Newtonian along with Newtonian flow in the post stenosis are examined through the mean velocity, wall shear stress, mean streamlines as well as turbulent kinetic energy and explained physically along with the relevant medical concerns.
Targeting Molecular Signals of Cell Cycle and Apoptosis in Anticancer Therapy-Brief Review

Cancer is a disease that severely affects the human population. The metastasis process of cancer possesses interrelated rate-limiting steps. This paper aimed to provide a brief review on targeting molecular signals of cell cycles and apoptosis which is essence of anticancer therapy. Tumour growth requires a new blood vessel induced by VEGF factor. Loss of heterozygosis occurs frequently at various chromosomal loci in a variety of human cancers. It also discusses the cyclin dependent kinase(CDK)-RB-E2F axis forms the core transcriptional machinery driving cell cycle progressing dictating the timing and fidelity of genome replication and ensuring genetic material is perfectly passed throughout each cell division. Apoptosis involves the activation of caspases which is a group of cysteine proteases and an intricate cascade of process that connect the initiating stimuli to the last termination of the cell. From the review, it was inferred that to target the molecular signals of cell cycle and apoptosis. It might be therapeutic approach for anti-cancer therapy.
The H-Metaphor as a Guideline for Vehicle Automation and Interaction

Good design is not free of form. It does not necessarily happen through a mere sampling of technologies packaged together, through pure analysis, or just by following procedures. Good design begins with inspiration and a vision, a mental image of the end product, which can sometimes be described with a design metaphor. A successful example from the 20th century is the desktop metaphor, which took a real desktop as an orientation for the manipulation of electronic documents on a computer. Initially defined by Xerox, then refined by Apple and others, it could be found on almost every computer by the turn of the 20th century. This paper sketches a specific metaphor for the emerging field of highly automated vehicles, their interactions with human users and with other vehicles. In the introduction, general questions on vehicle automation are raised and related to the physical control of conventional vehicles and to the automation of some late 20th century vehicles. After some words on design metaphors, the H-Metaphor is introduced. More details of the metaphor's source are described and their application to human-machine interaction, automation and management of intelligent vehicles sketched. Finally, risks and opportunities to apply the metaphor to technical applications are discussed.
Phasor Measurement Unit Testing

Our power system nowadays operate as a huge complex machine that often operate close to their stability limit. This means that any disturbances or faults may cause power oscillations and lead to cascade outages. Many efforts, therefore, have been on the way to build new, smart grids. These will be the grids that use the most advance monitoring, controlling, networking, and measurement technologies. One of those technologies is a device known as Phasor Measurement Unit (PMU). PMUs are devices which produce synchronized phasor, frequency and rate of change of frequency estimates from voltage and/or current and a time synchronizing signal [1]. The key driver for PMU technology is the use of the precise time sources provided by GPS satellites to accurately measure the relative voltage and current phase angles at buses across interconnected grids [2]. This technology is capable of directly measuring the phase angles across an interconnected power grid, which is the main advantage that PMUs have over traditional SCADAs. In the thesis, PMU behavior and IEEE Synchrophasor standards have been studied through simulation and measurements. Simulation is done on a software platform whereas measurement is performed at a company, VSL, to test a PMU on its measurement quality.
An offensive approach to teaching information security : 'Aachen summer school applied IT security

There is a general consensus that courses on data security at university degree level should be research-oriented and teach fundamentals of the field, i.e., items of long-term knowledge in contrast to technology-oriented system knowledge. Unfortunately, this consensus often results in courses that are either too theoretical or are outdated with respect to current developments in security technology. To understand the importance of information security, students should have the possibility to gain practical experience how security systems fail, using offensive techniques. In this article, we give an overview over a three-week intensive course on applied computer security we held at RWTH Aachen university. It brought together students from various countries and with different previous knowledge. We describe in detail the course outline, course contents and the lessons learned.
Multifaceted approached in gerating and recovering requirement traceability

Software evolution is inevitable. When a system evolves, there are certain relationships among software artifacts that must be maintained. Software must be continually changed to remain satisfactory in use. Requirement traceability is one of importance factor in facilitating software evolution since it maintains the artifacts relationship before and after a change is perfonned. This position paper aims at hypothesizing that utilizing a multifaceted approach to traceability generation and recovery can provide significant support for facilitating software evolution process. The multifaceted traceability approach contains three main facets that compose the whole traceability approach. Facet-l is a syntactical similarity matching process, Facet-2 is a link prioritization process, and Facet-3 is a heuristic-based process. Those three facets works in an integrated mode to construct traceability links among artifacts and are run on top of a particular ready-to-use integrated environment development (IDE) in order to facilitate the traceability generation and recovery as well as to ease the artifacts maintenance.
Characterisation of 3.3kV IGCTs for Medium Power Applications

The Low Voltage IGCT (3.3kV) is developed to provide a semiconductor able to work at high switching frequencies (>1kHz), preserving its « high current » capacity (4kA). The ultimate goal is to increase the dynamic performances of medium/high power converters, thus extending their application field. To characterise the experimental samples of 3.3kV IGCTs, an opposition method based test bench was developed. This method allows the components to be evaluated at different test conditions in real operation without the need of several megawatt power supplies. Once the samples were characterised, the applicability analysis of these components on specific applications related to the French railway network (SNCF) is performed. Finally, a reactive power compensation application for single-phase systems is studied in detail and a 100kVAR IGCT based set up is built.
Intermediate-Level Blends of Ethanol in Gasoline, and the Ethanol “Blend Wall”

This report discusses the growing interest in the potential for ethanol to displace petroleum as a transportation fuel, as well as related issues, including the current Clean Air Act (CAA) limitation on ethanol content in gasoline; the requests of ethanol producers for an increase of this limitation; and the effects the limitation has upon vehicle and engine warranties and the infrastructures of the automobile and fuel industries.
Managing reproduction - critical control points in exceeding 30 pigs per sow per year.

Producing 30 pigs weaned per sow per year (PSY) is now within the reach of many progressive pig units in Europe, Canada and the USA, with some enterprises already achieving this output. If the current rate of progress continues, then 30 PSY will become the average output for Denmark by around 2020. In Denmark, genetic selection for number born alive has been the key driver of increased sow productivity, but this has come at a price with pre-weaning mortality rates of 14%, as one of the highest amongst EU countries. Improvements in sow productivity will be achieved in most countries by a combination of measures, which include reductions in non-productive days through better management of the insemination step, adoption of higher standards for AI, timely introduction of gilts and culling of barren sows, combating seasonal infertility, reducing piglet losses before weaning, protecting high health status and having in place trained, skilled, rewarded and motivated stock people.
