The equation describing the magnetic field due to a single, nonrelativistic charged particle moving at constant velocity is often referred to as the "Biot-Savart law for a point charge."1 Introductory calculus-based physics books usually state this law without proof.2 Advanced texts often present it either without proof or as a special case of a complicated mathematical formalism.3 Either way, little or no physical insight is provided to the student regarding the underlying physics. This paper presents a novel, basic, and transparent derivation of the Biot-Savart law for a point charge based only on Maxwell's displacement current term in Ampere's law. This derivation can serve many pedagogical purposes. For example, it can be used as lecture material at any academic level to obtain the Biot-Savart law for a point charge from simple principles. It can also serve as a practical example of the important fact that a changing electric flux produces a magnetic field. © 2013 American Association of Physics Teachers.

Biosensing methods and devices using graphene oxide (GO) have recently been explored for detection and quantification of specific biomolecules from body fluid samples, such as saliva, milk, urine, and serum. For a practical diagnostics application, any sensing system must show an absence of nonselective detection of abundant proteins in the fluid matrix. Because lysozyme is an abundant protein in these body fluids (e.g., around 21.4 and 7 μg/mL of lysozyme is found in human milk and saliva from healthy individuals, and more than 15 or even 100 μg/mL in patients suffering from leukemia, renal disease, and sarcoidosis), it may interfere with detections and quantification if it has strong interaction with GO. Therefore, one fundamental question that needs to be addressed before any development of GO based diagnostics method is how GO interacts with lysozyme. In this study, GO has demonstrated a strong interaction with lysozyme. This interaction is so strong that we are able to subsequently eliminate and separate lysozyme from aqueous solution onto the surface of GO. Furthermore, the strong electrostatic interaction also renders the selective adsorption of lysozyme on GO from a mixture of binary and ternary proteins. This selectivity is confirmed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), fluorescence spectroscopy, and UV-vis absorption spectroscopy. © 2014 American Chemical Society.

Evaluation and Program Planning | Year: 2013
Evaluation of research capacity building programs presents challenges, including defining " research capacity building" and measuring it. The present study evaluates infrastructure capacity-building strategies and barriers and facilitators of two federally funded health-related research capacity building programs within the United States. We developed a conceptual framework and abstracted 223 data elements from existing project files. We administered questionnaires to 17 principal investigators and conducted 2-h interviews of 15 principal investigators. Finally, we conducted one-and-a-half-day site visits with five projects. We aggregated data and analysis results across the two programs. Impacts and strategies were also analyzed as to whether host institutions had little or no existing research infrastructure (" seed projects" ) or had well-developed research infrastructure (" fertilizer projects" ). Projects were associated with increases in publication and presentation rates by Principal Investigators and staff, increases in research funding, changes in organizational research culture, and positive impacts on the community. Project characteristics and activities associated with each of these outcomes were identified. It was also noted that the correlations between these outcomes were small and non-significant. © 2012 Elsevier Ltd.

Airwolf 3D today announced Wolfbite ULTRA™, a premium solution specifically engineered to solve the problem of polypropylene parts warping because they fail to adhere to a 3D printer's build plate. Wolfbite ULTRA™ bonds polypropylene plastic parts to a build plate to allow printing without lifting and to enable smooth release of objects after printing. This new solution works well with heated beds on all types and brands of 3D printers utilizing glass printing surfaces. Polypropylene is widely used for automotive and other industrial applications because it is extremely durable and cost effective. From carpets and bottles to automotive bumpers, chemical tanks, and limitless custom solutions, this type of plastic has such an extensive number of uses because it is incredibly chemically resistant while being almost completely waterproof. While used in many products, polypropylene is notorious in the 3D printing community for being difficult to work with because of bed adhesion problems. Polypropylene parts have a high tendency to warp or even completely fail to stick to the print bed. As the manufacturer of the only desktop 3D printer in its price class to effectively print polypropylene, Airwolf 3D created Wolfbite ULTRA™ to meet the demands of customers who require the ability to print in the high-performance industrial material. "Airwolf 3D is extremely fortunate to work with customers who are leaders and early adopters in their respective industries," stated Airwolf 3D Co-Founder and Lead Designer Erick Wolf. "When customers come to us with a problem, it gives us an opportunity to devise an innovative solution for them. We developed Wolfbite ULTRA™, along with the new AXIOM 20 printer, in response to a surge of automotive customers asking us to help them 3D print in polypropylene. It is exciting to be at the forefront of a technology that will meet the growing demands of the automotive, engineering, and other manufacturing industries as more and more professionals adopt 3D printing as part of their work flow." Wolfbite ULTRA™ was developed at Airwolf 3D through a collaboration with Professor Miodrag "Mickey" Micic, Sc.D., Ph.D., M.T.M., department chairman at Cerritos College in Norwalk, CA, and renowned polymer chemist and additive manufacturing expert. "Polypropylene, a completely saturated hydrocarbon macromolecule, is extremely difficult to bind and is virtually unreactive to anything," said Prof. Micic. "The new Wolfbite ULTRA™ is the first solution in the world to offer effective, reversible adhesion between the hydrophilic material of the printer bed, such as glass or borosillicate glass, and polypropylene parts. Furthermore, Wolfbite ULTRA™ is a water-based, "green" chemistry solution and an environmentally safe product." As the first product of its kind, Wolfbite ULTRA™ empowers professionals to directly 3D print their parts in polypropylene. As Prof. Micic pointed out, "Many prototypes currently are 3D printed in ABS or PLA and are later transferred into manufacturing by injection molding polypropylene. For the first time, a user can rapid prototype a part from the same material used for the final product and have the ability to test its exact properties before moving into final mass production. Polypropylene is a clinically inert resin that will expand the effective use of 3D printers, especially for medical devices, process technologies, automotive, and chemical storage." Wolfbite ULTRA™ Is packaged in a two-fluid-ounce container and comes with a foam brush applicator. It is currently available for sale on the Airwolf 3D website at an introductory price of $39.95. Airwolf 3D is committed to designing, manufacturing and selling 3D printers, 3D Printing software, and 3D printing peripherals that are fast, affordable, durable and easy to use. Airwolf 3D has authorized dealers in more than 20 countries around the world. Airwolf 3D printers are delivered fully assembled and ready to print. All Airwolf 3D printers are made in America and manufactured in the company’s 12,000 sq. ft. facility in Costa Mesa, California. Airwolf 3D printers can be found in Fortune 500 companies, engineering firms, government agencies and schools worldwide.

Multiple measures of sexual minority status are necessary to accurately describe the diversity of attractions, identities, and behaviors in sexual minority populations. We investigated whether four measures of sexual minority status (sexual minority attraction, sexual minority identity, sexual minority lifetime behavior, and sexual minority recent 12-month behavior) were associated with suicidal thoughts and suicide attempts among young adults ages 24 to 34 in the United States. We analyzed data from Wave IV (2007-2008) of the National Longitudinal Study of Adolescent Health. We employed logistic regression models in the analysis. Multiple sexual minority status measures had significant associations with increased suicidal thoughts among women and men. Multiple sexual minority status measures had significant associations with increased suicide attempts among women, but not among men. Diverse sexual minority populations are at increased risk for suicidal thoughts and suicide attempts. Multiple measures of sexual minority status should be utilized in future studies of sexual minority status and suicide risk. Suicide prevention programs should ensure intervention is available across diverse sexual minority populations. © 2014 Copyright International Academy for Suicide Research.
