Authors: Koganti Vijay Prasad , Sekhar L Chandra , Shankar B Ravi , Gopinath A 
Published: January 2012

ABSTRACT
The present clinical study was undertaken to determine the effects of splinting overunsplinted mobile teeth following periodontal surgery and compared the efficacy of two splinting materials, i.e. Ribbond ribbon + Composite with Stainless steel wire + Composite.

Materials and methods
Total of 30 patients (20 experimental and 10 control) formed the study group. Entire study was extended over a period of 12 weeks for each patient and treatment plan was divided into 8 phases. Healing response was monitored and application, durability, biocompatibility of splint material was assessed.

Results
Splint had a promising and beneficial effects on anterior teeth exhibiting Grade I to Grade II degrees of mobility. Experimental group showed a greater reduction in tooth mobility compared to control group. There was no significant difference in plaque index and Ribbond Ribbon reinforced with composite resin was an excellent material for application, patient comfort, resistance to fracture, biocompatable and esthetic acceptability.

Clinical significance
Splinting is recommended as an adjunct to periodontal surgery in the treatment of hypermobile teeth, especially in cases where patient discomfort is a prominent factor.

Histopathologic Diversity of Gorlin's Cyst: A Study of Four Cases and Review of Literature
Authors: Gupta Indra , Sonawane Kishore , Singaraju Medhini , Singaraju Sasidhar 
Published: January 2012

ABSTRACT

Aim
The purpose of the present article is to discuss four different case reports of the so-called calcifying odontogenic cyst and highlight the histopathological diversity of the same.

Background
Calcifying odontogenic cyst was first described by Gorlin et al in 1962. Ever since, its identification as a specific odontogenic lesion, controversies and confusions have existed regarding the relationship between cystic lesions and solid tumor masses that share cellular and histomorphologic features. Although several classifications were proposed, dilemma still persists regarding the nature of these lesions as cysts, neoplasms and even malignancies.

Conclusion and clinical significance
The classifications discussed for the so-called calcifying odontogenic cyst by various authors have only added to further confusion rather than enlightening. Though many authors state that classifications remain only an academic exercise, it definitely has significance in treatment planning. Emphasis should, therefore, be laid on a universally accepted classification.

Effect of polymerization and preheating processes on poly(ethylene terephthalate) depolymerization
Authors: Asakuma Yusuke , Koga Daisuke , Nakagawa Kyuya , Maeda Kouji , Fukui Keisuke 
Published: January 2012

AbstractThe depolymerization reaction of poly(ethylene terephthalate) (PET) was analyzed on the basis of experimental and numerical data obtained from molecular orbital calculations. Various types of PETs polymerized by different methods and preheated by microwave irradiation were used to investigate the depolymerization mechanism. The activation energies obtained from the optimized structures of the ground state and the transition state were compared with the experimental data. On the basis of these comparisons, it was found that not only the crystallinity but also configuration changes caused by preheating were essential for realizing a high rate of transesterification reactions, such as depolymerization. © 2012 Wiley Periodicals, Inc.

Sol–gel synthesis and characterization of polyimides based on the reaction of butane‐1,2,3,4‐tetracarboxylic acid with 3‐aminopropyltriethoxysilane
Authors: Schramm Christian , Rinderer Beate , Tessadri Richard 
Published: January 2012

AbstractButane‐1,2,3,4‐tetracarboxylic acid is reacted with hydrolyzed 3‐aminopropyltriethoxysilane (APTES) at 110 and 220°C (molar ratios 1 : 1 and 1 : 2). The as‐prepared materials were characterized by means of various analytical methods. FTIR measurements revealed the formation of a polyamic acid at 110°C whereas the treatment at 220°C resulted in the preparation of a polyimide. These findings were confirmed by means of SS‐13C‐MAS‐NMR. XRPD experiments gave clear evidence for the formation of a specific periodic arrangement in the material. Thermogravimetric analysis indicated that the organic–inorganic material has improved thermal properties. All the materials obtained were insoluble in water and organic solvents. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

AbstractAn experimental approach was used to assess immunological biomarkers in the sera of young rats exposed in utero and postnatal to non‐ionizing radiofrequency fields. Pregnant rats were exposed free‐running, 2 h/day and 5 days/week to a 2.45 GHz Wi‐Fi signal in a reverberation chamber at whole‐body specific absorption rates (SAR) of 0, 0.08, 0.4, and 4 W/kg (with 10, 10, 12, and 9 rats, respectively), while cage control rats were kept in the animal facility (11 rats). Dams were exposed from days 6 to 21 of gestation and then three newborns per litter were further exposed from birth to day 35 postnatal. On day 35 after birth, all pups were sacrificed and sera collected. The screening of sera for antibodies directed against 15 different antigens related to damage and/or pathological markers was conducted using enzyme‐linked immunosorbent assay (ELISA). No change in humoral response of young pups was observed, regardless of the types of biomarker and SAR levels. This study also provided some data on gestational outcome following in utero exposure to Wi‐Fi signals. Mass evaluation of dams and pups and the number of pups per litter was monitored, and the genital tracts of young rats were observed for abnormalities by measuring anogenital distance. Under these experimental conditions, our observations suggest a lack of adverse effects of Wi‐Fi exposure on delivery and general condition of the animals.

Computational Fluid Dynamics Simulation of 13CO Distillation in Structured Packing
Authors: Li H.‐L. , Ju Y.‐L. , Li L.‐J. , Xu D.‐G. 
Published: January 2012

AbstractPhysical 3D models were established for corrugated packing used in the enrichment of the isotope 13C. Computational fluid dynamics (CFD) simulation results indicated that common corrugated packing was not well wetted when used for isotope distillation. It is concluded that liquid misdistribution in the packed tower results from the structure of the packing rather than from the height of the packing beds. The existence of entrainment was also demonstrated by CFD simulation. It is proved that mass transfer equations based on the Nusselt theory are not suitable for distillation calculation in such a corrugated packing system. By comparison, the recently developed structured packing model with a corrugation geometry based on the right‐angled triangle, known as Zigzag‐pak, describes vapor‐liquid distribution properties well and has significant advantages over common corrugated packing due to its better liquid distribution character.

A critical center‐stable manifold for Schrödinger's equation in three dimensions
Authors: Beceanu Marius 
Published: January 2012

AbstractConsider the focusing
$\dot H^{1/2}$‐critical semilinear Schrödinger equation in $\font\open=msbm10 at 10pt\def\R{\hbox{\open R}}\R^3$

It admits an eight‐dimensional manifold of special solutions called ground state solitons.We exhibit a codimension‐1 critical real analytic manifold
${\cal N}$
of asymptotically stable solutions of (0.1) in a neighborhood of the soliton manifold. We then show that ${\cal N}$
is center‐stable, in the dynamical systems sense of Bates and Jones, and globally‐in‐time invariant.Solutions in
${\cal N}$
are asymptotically stable and separate into two asymptotically free parts that decouple in the limit—a soliton and radiation. Conversely, in a general setting, any solution that stays $\dot H^{1/2}$‐close to the soliton manifold for all time is in ${\cal N}$.The proof uses the method of modulation. New elements include a different linearization and an endpoint Strichartz estimate for the time‐dependent linearized equation.The proof also uses the fact that the linearized Hamiltonian has no nonzero real eigenvalues or resonances. This has recently been established in the case treated here—of the focusing cubic NLS in
$\font\open=msbm10 at 10pt\def\R{\hbox{\open R}}\R^3$—by the work of Marzuola and Simpson and Costin, Huang, and Schlag. © 2012 Wiley Periodicals, Inc.
Seasonality of water and carbon dioxide exchanges at a teak plantation in northern Thailand
Authors: Igarashi Yasunori , Tanaka Nobuaki , Tanaka Katsunori , Yoshifuji Natsuko , Sato Takanori , Tantasirin Chatchai , Suzuki Masakazu 
Published: January 2012

ABSTRACTThe object of this study was to elucidate the seasonal patterns of energy partitioning of net radiation into sensible and latent heat fluxes and carbon dioxide (CO2) flux at a tropical deciduous forest site, i.e. a teak plantation in northern Thailand. In general, latent heat flux was more prominent than sensible heat flux in the wet (growing) season, whereas in the dry (dormant) season, sensible heat was the main form of energy emitted to the atmosphere. More specially, latent heat flux began to increase before leaf‐out of teak trees and decreased 1 month earlier than leaf‐fall initiation. Daytime net CO2 uptake appeared to increase with increasing amount of leaves but only at the beginning of the wet season; values peaked during the early part of wet season; and declined thereafter. This decline occurred about 3 months earlier than when latent heat flux began to decrease about 4 months earlier than the leaf‐fall initiation. These results indicate that the seasonality of water and CO2 exchanges between the atmosphere and the tropical deciduous forest was substantially decoupled during the late wet season. This decoupling of the seasonality of water and carbon exchanges may be particularly important when modelling the ecohydrology of this tropical deciduous forest.
