To eliminate the requirement for skilled workers in Video cassette recorder (VCR) cylinder assembly lines, an automatic adjustment system for VCR magnetic heads on a rotating cylinder unit has been newly developed. The reconstructed image quality is strongly affected by magnetic head setting errors, such as; ( I ) Setting angle error for two symmetrically positioned head. (2) Rotational angle e...

BACKGROUND Students may have different learning styles. It is unclear, however, whether tailoring instructional methods for a student's preferred learning style improves educational outcomes when teaching procedures. The authors sought to examine whether teaching to a student's self-perceived learning style improved the acquisition of intravenous (IV) catheter placement skills. The authors hypo...

The ability to protrude the jaws and capture elusive prey is a hallmark of fish evolution. New analyses provide insight into how jaw protrusion changed predator-prey relationships and fueled species diversification in ancient seas.

The four-point modified Mallampati (MMP) score is widely used as a marker of difficult intubation. The evaluation is usually performed by having patients open their mouth and protrude their tongue with the head and neck in a neutral position. However, mouth opening has been shown to be greater when the head and neck are extended. In this study, examiners with a minimum of 1 year of airway exper...

The asymmetric unit of the title salt, {(C(12)H(20)N(4))[Ag(2)Br(4)]}(n), contains one-half of a substituted imidazolium cation, one Ag(+) and two Br(-) ions. The cation is completed by crystallographic inversion symmetry. The crystal structure is made up from polymeric sheets of {[AgBr(2)](-)}(n) anions extending parallel to (100). The basic building unit of the anion is a slightly distorted A...

When Xenos peckii twisted-wing parasite males emerge as adults from within the body of the hapless wasp that served as their incubator, the race is on. With an adult lifetime spanning just a few hours, the male insects have to locate a female and mate before their time is up. And the challenge of locating a female mate – which is barely more than a fleshy bag of eggs with no eyes or limbs – is ...

Objective: In the current investigation, we aimed to study the combined cytotoxicity of curcumin, as a nanomicellar formulation, and galbanic acid (Gal), dissolved in DMSO against the murine C26 and human Caco-2 colon carcinoma cells. Further, curcumin potential for cisplatin and doxorubicin (Dox) co-therapy was studied. <span styl...
