Published: March 2012

Abstract

Introduction
Anatomic variations of the paranasal sinuses are very common. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extensive use of endoscopic sinus surgery.

Case presentation
A 53-year-old Caucasian woman was admitted to our clinic with complaints of nasal breathing difficulties and headache persisting for a long time. Another concha bullosa was detected in the middle concha bullosa on preoperative paranasal computed tomography examination. It is known that the paranasal sinuses have a number of anatomical variations.

Conclusion
Herein we report a rare case, along with a review of the literature, to emphasize that a concha bullosa inside another concha bullosa should not be ignored.
In Vitro assessment of the nutritive value of expanded soybean meal for dairy cattle
Authors: Elwakeel Eman A , Titgemeyer Evan C , Cheng Zongjia J , Nour Abdelaziz M , Nasser Mohamed EA 
Published: March 2012

Abstract
Little information is available about the nutritive value of expanded soybean meal, which is produced by expansion of soybeans prior to solvent extraction of the oil. During processing, expanded soybean meal is subjected to additional heat, which might increase the concentration of ruminally undegraded protein. Processing of soybeans with heat during oil extraction could affect lysine availability by increasing ruminally undegraded protein or by impairing intestinal digestion. Our objective was to compare solvent and expanded soybeans with regard to chemical composition and nutritive value for dairy cattle. Samples of expanded soybean meal (n = 14) and solvent-extracted soybean meal (n = 5) were obtained from People's Republic of China to study effects of the expansion process on nutritive value for dairy cattle. Solvent-extracted soybean meal (n = 2) and mechanically extracted (heated) soybean meal (n = 2) from the United States served as references for comparison. Samples were analyzed for crude fat, long-chain fatty acids, crude protein, amino acids, chemically available lysine, in situ ruminal protein degradation, and in vitro intestinal digestibility. No differences were found between solvent-extracted soybean meals from China and expanded soybean meals from China for crude fat, crude protein, amino acids, or chemically available lysine. In situ disappearance of nitrogen, ruminally undegraded protein content, and in vitro intestinal digestion of the ruminally undegraded protein were generally similar between solvent-extracted soybean meals made in China and expanded soybean meals made in China; variation among soybean meals was small. Results indicate that the additional heat from the expansion process was not great enough to affect the nutritive value of soybean meal protein for ruminants. Although expansion may improve the oil extraction process, the impact on the resulting soybean meal is minimal and does not require consideration when formulating ruminant diets.

Authors: Ikeue Keita , Hinokuma Satoshi , Watanabe Kazuma , Minekishi Takayuki , Sato Takahiro , Nakahara Yunosuke , Machida Masato 
Published: March 2012

Abstract
The synthesis route of 10Al2O3·2B2O3 (10A2B) and effect of additives were studied to use this compound as a thermally stable support material for Pd catalysts. The preparation by reverse coprecipitation was found to have a beneficial effect on the BET surface area of 10A2B and thus Pd metal dispersion, compared to other preparation routes via solid-state reaction and hydrolysis of metal alkoxides. The addition of 3 wt % BaO suppressed the sintering of 10A2B and Pd during thermal aging at 900 °C in a stream of air containing 10% H2O. Although direct interactions between Pd and the support material were not detected by EXAFS, the catalytic performance for NO–CO–C3H6–O2–H2O reactions under modulated air-to-fuel ratio (A/F) conditions was strongly influenced by the Ba additive. The activity for NO and C3H6 in a rich region (A/F &lt; 14.6) was especially enhanced in the presence of Ba because of accelerated elemental reactions including NO–CO and NO–C3H6. In situ FT-IR of CO suggested that the Pd electronic state changed by electrostatic effect of Ba additives would activate NO and weaken the self-poisoning effect of C3H6.

Authors: Li Mao , Ishihara Shinsuke , Ji Qingmin , Ma Yuguang , Hill Jonathan P , Ariga Katsuhiko 
Published: March 2012

Abstract
Functional building blocks (fullerene and fluorene) were integrated into multilayers by utilizing electrochemical coupling layer-by-layer (ECC-LbL) assembly driven by the covalent carbon–carbon coupling reaction of pendant alkylcarbazoyl groups. The ECC-LbL assembly in patterning mode can be used to locally immobilize functional units and has been demonstrated here in a patterned fluorescent display. ECC-LbL is a versatile method for surface fabrication with promising potential in many applications.
General productivity: How become waxed and wax became a copula
Authors: Petré, Peter 
Published: March 2012

Abstract
This article provides an analysis—within the framework of Radical Construction Grammar—of how become developed into a copula ‘become’ out of an original sense ‘arrive’, and wax, originally ‘grow’, also came to be used as a copula ‘become’. Importantly, it explains why these verbs successfully became fully productive copulas in a very short period of time. It is argued that this happened after a pre-copular stage had reached a cognitive threshold value. The occurrence of this threshold is related to the fact that the copular constructions featuring become and wax were not the end result of a single diachronic lineage of constructions (i.e. one construction developed out of another one, one at a time). Instead, the copularization of these verbs was the result of an interaction between lineages of constructions, belonging to two groups: (i) constructions involving become or wax, which gradually changed and interacted with each other; (ii) constructions involving already existing copulas, notably weorđan ‘become’, which provided a generally productive analog upon which the newly emerging copulas could graft. Generally, the article calls attention to the importance of multiple source constructions and thresholds in understanding grammaticalization processes and productivity.
The tempered spectrum of quasi-split classical groups III:
The odd orthogonal groups
Authors: Goldberg David , Shahidi Freydoon 
Published: March 2012

Abstract.
We study the tempered spectrum of special orthogonal groups of odd degree over p-adic fields of characteristic zero. Residues of intertwining operators for representations parabolically induced from arbitrary maximal parabolic subgroups are determined in terms of non-vanishing of weighted sums of twisted orbital integrals. This is connected with the theory of twisted endoscopy, and poles of the Langlands L-functions, in particular, with the Rankin product L-function between irreducible (generic) supercuspidal representations of the classical group SO2m+1(F) and those of GLk(F). These poles are described for, any m and k, explicitly in terms of twisted endoscopy. Moreover, we show these poles describe precisely when a supercuspidal representation of GLk(F) is the local component of the transfer from a special odd orthogonal group.

Abstract
We answer in the affirmative a question posed by Ivanov
and Vassilev on the existence of a seven-dimensional
quaternionic contact manifold
with closed fundamental 4-form and non-vanishing
torsion endomorphism.
Moreover, we
show an approach to the classification of seven-dimensional solvable Lie groups having an integrable left invariant
quaternionic contact
structure. In particular, we prove that the
unique seven-dimensional nilpotent Lie group admitting such a structure
is the quaternionic Heisenberg group.

On Lp
resolvent estimates for Laplace–Beltrami operators on compact manifolds
Authors: Dos Santos Ferreira David , Kenig Carlos E. , Salo Mikko 
Published: March 2012

Abstract.
In this article we prove Lp
estimates for resolvents of Laplace–Beltrami operators on compact Riemannian manifolds, generalizing results of Kenig, Ruiz and Sogge (1987) in the Euclidean case and Shen (2001) for the torus. We follow Sogge (1988) and construct Hadamard's parametrix, then use classical boundedness results on integral operators with oscillatory kernels related to the Carleson and Sjölin condition. Our initial motivation was to obtain Lp
Carleman estimates with limiting Carleman weights generalizing those of Jerison and Kenig (1985); we illustrate the pertinence of Lp
resolvent
estimates by showing the relation with Carleman estimates. Such estimates are useful in the construction of complex
geometrical optics solutions to the Schrödinger equation with unbounded potentials, an essential device for solving
anisotropic inverse problems.

Probing nanoscale behavior of magnetic materials with soft X-ray spectromicroscopy
Authors: Fischer Peter , Fadley Charles S. 
Published: March 2012

AbstractThe magnetic properties of matter continue to be a vibrant research area driven both by scientific curiosity to unravel the basic physical processes which govern magnetism and the vast and diverse utilization of magnetic materials in current and future devices, e.g., in information and sensor technologies. Relevant length and time scales approach fundamental limits of magnetism and with state-of-the-art synthesis approaches we are able to create and tailor unprecedented properties. Novel analytical tools are required to match these advances and soft X-ray probes are among the most promising ones. Strong and element-specific magnetic X-ray dichroism effects as well as the nanometer wavelength of photons and the availability of fsec short and intense X-ray pulses at upcoming X-ray sources enable unique experimental opportunities for the study of magnetic behavior. This article provides an overview of recent achievements and future perspectives in magnetic soft X-ray spectromicroscopies which permit us to gain spatially resolved insight into the ultrafast spin dynamics and the magnetic properties of buried interfaces of advanced magnetic nanostructures.
Re-thinking the role of intellectual property in nano-strategy
Authors: Giordani Sara 
Published: March 2012

AbstractIn two past studies we observed and analyzed a group of European new and adolescent ventures, looking in particular at how they were about exploiting nanotechnology-based business opportunities, what was the role of intellectual property rights (IPRs), mainly patents, in those strategies, what was the link between patent filings in nanotechnology and exploitation patterns in the market. We formulated hypotheses and proposed an interpretative model of the strategic decisions and business choices. After a couple of years we took the opportunity to revisit some of the hypotheses and outcomes of the proposed interpretative model. If the overall framework of analysis is still, at least partly, applicable to the current situation, new trends emerge, which involve: the creation of extended portfolios of IPRs and intangible assets, which are both technology and marketing related, the entry of strategic investors and the new role of the financial and funding instruments, and the emergence of new types of consolidation patterns which are rooted in the net of strategic partnerships, collaborations and new forms of alliances in the supply chain and in the market.
Facilitating teachers’ development of nanoscale science, engineering, and technology content knowledge
Authors: Bryan Lynn A. , Sederberg David , Daly Shanna , Sears David , Giordano Nicholas 
Published: March 2012

AbstractAs nanoscale science, engineering, and technology (NSET) becomes more integrated into precollege science curricula, it is crucial for teachers to develop coherent understandings of science principles (e.g., the structure of matter, size and scale, forces and interactions, and size-dependent properties) that allow them to coordinate these understandings from the macro- to the nanoscale. Furthermore, as teachers acquire new NSET content knowledge through professional learning opportunities, it is incumbent upon NSET educators to understand their developing content knowledge. To this end, we report results from a study in which we used a pre-/post-/delayed-posttest design to examine the change in 24 secondary (grades 7–12) science teachers’ NSET content knowledge as a result of their participation in a year-long professional development program that consisted of a 2-week intensive course and academic year follow-up activities. Participants showed significant gains from pretest to posttest and significant gains on the delayed test compared to the pretest. We also present trends that emerged in teachers’ open-ended responses that provided deeper insight into teachers’ NSET content knowledge. Finally, we discuss issues related to the assessment of teachers’ NSET content knowledge as well as the design of NSET professional development for teachers.

Effect of a New Anti‐Plaque Agent (CK‐0569A) on Developing Plaque and Gingivitis in Man
Authors: Wennström Jan L. 
Published: March 2012

This study investigated the effect of l,4‐bis[3‐(n‐hexylcarbamylguanidine)propyl]piperazine dimethanesulfonic acid salt (CK‐0569A), used as a mouthrinse, on the development of plaque and gingivitis in humans. Fourteen dental students participated in a double‐blind cross‐over study. At the start of each of the two 14‐day periods of mouthrinsing (one period with CK‐0569A and one period with a placebo solution) the participants were examined for the presence of plaque (PlI) and gingivitis (GI). In addition, supragingival plaque samples were obtained and analyzed by darkfield microscopy. Clinical examination of plaque and gingivitis was repeated 4, 7 and 14 days after the start of the no‐toothbrushing periods. Bacterial samples were obtained after 7 and 14 days of trial.The results demonstrated that a mouthrinse containing CK‐0569A prevented the colonization of motile + curved rods and spirochetes in developing plaque. Furthermore, rinsing twice daily with 0.1% solution CK‐0569A significantly reduced the amount of dental plaque formed and retarded the development of gingivitis.
Relationship Between Alveolar Bone Measured by 125I Absorptiometry With Analysis of Standardized Radiographs: 2. Bjorn Technique
Authors: Ortman Lance F. , McHenry Kenneth , Hausmann Ernest 
Published: March 2012

The bjorn technique is widely used in periodontal studies as a standardized measure of alveolar bone. Recent studies have demonstrated the feasibility of using 125I absorptiometry to measure bone mass. The purpose of this study was to compare 125I absorptiometry with the Bjorn technique in detecting small sequential losses of alveolary bone.Four periodontal‐like defects of incrementally increasing size were produced in alveolar bone in the posterior segment of the maxilla of a human skull. An attempt was made to sequentially reduce the amount of bone in 10% increments until no bone remained, a through and through defect. The bone remaining at each step was measured using 125I absorptiometry. At each site the 125I absorptiometry measurements were made at the same location by fixing the photon source to a prefabricated precision‐made occlusal splint. This site was just beneath the crest and midway between the borders of two adjacent teeth. Bone loss was also determined by the Bjorn technique. Standardized intraoral films were taken using a custom‐fitted acrylic clutch, and bone measurements were made from the root apex to coronal height of the lamina dura. A comparison of the data indicates that: (1) in early bone loss, less than 30%, the Bjorn technique underestimates the amount of loss, and (2) in advanced bone loss, more than 60%, the Bjorn technique overestimates it.
