Pittsburg State University, also called Pitt State or PSU is a public university with approximately 7,479 students located in Pittsburg, Kansas, United States. A large percentage of the student population consists of residents within the Pittsburg region; the gender proportion is relatively equal. Almost 89% of the students are Americans. Pitt State also has an 19:1 student-to-faculty ratio. It is a member of the Kansas Board of Regents. Currently, it has an endowment of around $74,000,000. The student newspaper of Pittsburg State University is the Collegio. Wikipedia.

A uniform, compact, and well adherent conversion coating of magnesium hydroxide has been formed on bioresorbable magnesium disks by means of a hydrothermal technique. Electrochemical results indicate that the coating brings about a significant reduction in magnesium corrosion in phosphate buffered saline (PBS) solution. It is also observed that corrosion resistance of the coating increases with an increase in treatment time, which in turn, increases the coating thickness. The protective behavior of magnesium hydroxide coating is attributed to its chemical inertness in PBS solution. The coatings are found to be free from pores that reduce the direct contact between corroding media and underlying magnesium. © 2013.

In this paper, the development and assessment of a curriculum covering field programmable gate arrays (FPGAs) will be discussed. An FPGA is a programmable logic device which consists of programmable logic blocks with programmable interconnections. An FPGA may consist of millions of equivalent logic gates. The motivation for the development of the FPGA curriculum was the need for students to be proficient in FPGAs. This need was assessed by two events. At a meeting of the EET industrial advisory committee, the need for employees proficient in FPGAs was expressed. In addition, the software company Altium Limited expressed an interest in working with the EET program to develop FPGA curriculum material for a university program. In the fall semester of 2011, the FPGA curriculum was used in an advanced digital logic course. Previously, programmable array logic (PAL) devices and generic array logic (GAL) devices were used. This course serves as a required course in the newly created embedded systems emphasis area in the fouryear undergraduate Electronics Engineering Technology (EET) program at Pittsburg State University in Pittsburg, Kansas. It is planned to include the FPGA material in future offerings of the course.

Plant viruses are a class of plant pathogens that specialize in movement from cell to cell. As part of their arsenal for infection of plants, every virus encodes a movement protein (MP), a protein dedicated to enlarging the pore size of plasmodesmata (PD) and actively transporting the viral nucleic acid into the adjacent cell. As our knowledge of intercellular transport has increased, it has become apparent that viruses must also use an active mechanism to target the virus from their site of replication within the cell to the PD. Just as viruses are too large to fit through an unmodified plasmodesma, they are also too large to be freely diffused through the cytoplasm of the cell. Evidence has accumulated now for the involvement of other categories of viral proteins in intracellular movement in addition to the MP, including viral proteins originally associated with replication or gene expression. In this review, we will discuss the strategies that viruses use for intracellular movement from the replication site to the PD, in particular focusing on the role of host membranes for intracellular transport and the coordinated interactions between virus proteins within cells that are necessary for successful virus spread. © 2011 The Author.

Plant viruses are obligate organisms that require host components for movement within and between cells. A mechanistic understanding of virus movement will allow the identification of new methods to control virus systemic spread and serve as a model system for understanding host macromole- cule intra- and intercellular transport. Recent studies have moved beyond the identification of virus proteins involved in virus movement and their effect on plasmodesmal size exclusion limits to the analysis of their interactions with host components to allow movement within and between cells. It is clear that individual virus proteins and replication complexes associate with and, in some cases, traffic along the host cytoskeleton and membranes. Here, we review these recent findings, highlighting the diverse associations observed between these components and their trafficking capacity. Plant viruses operate individually, sometimes within virus species, to utilize unique interactions between their proteins or complexes and individual host cytoskeletal or membrane elements over time or space for their movement. However, there is not sufficient information for any plant virus to create a complete model of its intracellular movement; thus, more research is needed to achieve that goal © 2010 The American Phytopathological Society.

A new interesting class of conducting polymer and copolymers based on 4-teriary butyl-cyclohexanone in the main chain has been synthesized by solution polycodensation of terephthalaldehyde with 4-teriary butyl-cyclohexanone and/or cycloalkanone derivatives. The model compound I was synthesized from the 4-teriary butyl-cyclohexanone with benzaldehyde, and its structure was confirmed by elemental and spectral analyses. The resulting polymer and copolymers were characterized by elemental and spectral analyses including Fourier transform infrared spectrometer (FT-IR) and nuclear magnetic resonance ( 1H-NMR), beside solubility and viscometry measurements. The thermal properties of those polymer and copolymers were evaluated by thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) measurements and correlated to their structural units. X-ray analysis showed that it has some degree of crystallinity in the region 2θ = 5-60°. The UV-visible spectra of some selected polymers were measured in dimethyl sulfoxide (DMSO) solution and showed absorption bands in the range 253-398 nm, due to n-π* and π-π* transition. The morphological properties of selected examples were tested by scanning electron microscope (SEM). Moreover, the electrical conductivities and the doping with iodine were tested. © 2011 Wiley Periodicals, Inc.
