Consumer perception of extruded snacks containing brown rice and dried mushroom

Effects of mushroom type, seasoning and health benefit information (HBI) on consumers’ saltiness expectation, sensory liking, elicited emotions and purchase intent (PI) of extruded snacks were investigated. Five snacks were evaluated: straw mushroom (Volvariella volvacea) extrudates without (SME) or with seasoning (SMES), phoenix mushroom (Pleurotus pulmonarius) extrudates without (PME) or with seasoning (PMES), and the control without mushroom and seasoning. Hedonic scores and positive emotions were generally higher for seasoned mushroom-containing snacks (SMES and PMES) with 65% and 75.83% of consumers reporting willingness to purchase, respectively, after receiving HBI. Bored, interested and satisfied were identified as significant emotional predictors for PI odds. Flavour, saltiness, overall liking, bored, good and interested were critical attributes, differentiating snacks. This study demonstrated that sensory liking and PI of extruded brown rice-based snacks containing mushroom could be improved through savoury seasoning addition, which also allowed saltiness expectations to be met.     

Controlled Secure Direct Communication Protocol via the Three-Qubit Partially Entangled Set of States

In this paper, we first re-examine the previous protocol of controlled quantum secure direct communication of Zhang et al.’s scheme, which was found insecure under two kinds of attacks, fake entangled particles attack and disentanglement attack. Then, by changing the party of the preparation of cluster states and using unitary operations, we present an improved protocol which can avoid these two kinds of attacks. Moreover, the protocol is proposed using the three-qubit partially entangled set of states. It is more efficient by only using three particles rather than four or even more to transmit one bit secret information. Given our using state is much easier to prepare for multiqubit states and our protocol needs less measurement resource, it makes this protocol more convenient from an applied point of view.     

A cathode support structure for use in a magnetron oscillator experiment

A low temperature co-fired ceramic (LTCC) material system has been used to develop a protype field emission cathode structure for use in an experimental magnetron oscillator. The structure is designed for used with 30 gated field emission array (GFEA) die electrically connected through silver metal traces and electrical vias. To approximate a cylinder, the cathode structure (48 mm long and 13.7 mm in diameter) is comprised of 10 faceted plates which cover the GFEA dies. Slits in the facet plates allow electron injection. The GFEA die (3 mm × 8 mm) are placed in axial columns of 3 and spaced azimuthally around a cylindrical support structure in a staggered configuration resulting in 10 azimuthal locations. LTCC manufacturing techniques were developed in order to fabricate the newly designed cathode with seven layers wrapped to form the cylinder with electrical traces and vias. Two different cathode wrapping techniques and two different via filling techniques were studied and compared. Two different facet plate manufacturing techniques were studied. Finally, four different support stand configurations for firing the cylindrical structure were also compared with a square post stand having the best circularity and linearity measurements of the fired structure.     

Influence of schedule and mode of administration on effectiveness of podofilox treatment of papillomas

We investigated the timing of podofilox delivery to see how it correlated with papilloma size. We looked at times ranging from once per week (morning and afternoon) to five times per week (morning and afternoon). We also looked at delivery systems that might enhance the effectiveness of the drug by increasing penetration of the overlying cutaneous horn. These included soaking prior to drug administration, the use of a grooved needle subsequent to drug administration, and the various possible combinations of these techniques. We found that the timing of treatments had relatively little effect on the size of the papillomas. For example, at the end of ten weeks, the geometric mean diameter (GMD) (mm) of the papillomas treated five times per week and induced by a 10(-1) dilution of the virus (group B) was 18. Likewise the GMD (mm) of papillomas treated once per week was 18 (group D). On the other hand, we found that soaking plus the use of a grooved needle plus podofilox resulted in the curing of all lesions induced by a 10(-2) virus dilution and of most induced by the 10(-1) dilution, whereas soak plus podofilox or podofilox alone were not as effective in curing the lesions. Podofilox plus needle approached the soak plus podofilox plus needle in effectiveness. Treatment schedule was not a critical determinant of podofilox effectiveness. Therapeutic benefits were enhanced by hydration of the overlying cutaneous horn and penetration with a grooved needle.     

Using a cost-construction model to assess the cost of educating undergraduate medical students at the University of Texas--Houston Medical School

Spontaneous resolution of deformities after excision of facial skin lesions has been known and used for a long time by plastic surgeons. The resorption mechanism of deformity is based on natural skin expansion, and seems to be directly related to the action of the muscles of facial expression and their skin relations. Natural expansion has been shown to be effective in children. Between 1990 and 1994 excision of skin lesions, including congenital nevi, leading to postoperative deformity of the cheek, labial commissure, nose, eyelid and forehead, was performed on 35 patients, aged from 3 month to 12 years. The average follow-up is 24 months. For 26 patients (74%), natural resorption was observed 4 or 6 weeks later with good aesthetic results. For 6 patients (17%), the deformity persisted 3 or 6 months later, but did not require any further surgery. For 3 patients (9%), a second operation was necessary. Using the skins natural capacity for expansion in the treatment of facial skin defects in children is a method of reconstruction which has already been used for excision in enforced position. The platysma and muscles of facial expression by their action on skin mobilisation, allow natural expansion. A better knowledge of cutaneous biomechanical properties enables plastic surgeons to find an alternative to other classical methods.     

Childhood fibrous dysplasia presenting as blindness: a skull base approach for resection and immediate reconstruction

Fibrous dysplasia is an abnormal fibroosseous process of bone of unknown cause. The incidence of skull involvement varies, painless enlargement being the most common presenting symptom. Change in vision is a rare but recognized finding. We report a 3-year-old boy with extreme fibrous dysplasia involving the skull base, who presented with blindness. He underwent exposure osteotomies of the frontal bones and orbits to provide access for skull base tumor removal. The orbital roofs were reconstructed with microplate-fixed cranial grafts. One and one half years after tumor excision followed by immediate reconstruction, the boy retains facial symmetry, and his ocular function has not deteriorated.
