Shrinkage behavior of poly(ethylene terephthalate) for a new cementitious–shrinkable polymer material system
Authors: Dunn S. C. , Jefferson A. D. , Lark R. J. , Isaacs B.
Published: December 2010

An investigation of the transient thermomechanical behavior of poly(ethylene terephthalate) (PET) is presented with respect to a new composite material system in which shrinkable PET tendons are incorporated into a cementitious matrix to provide a crack‐closure mechanism. A series of parametric studies of the effects of the geometry, temperature, and soak time on the mechanical properties of the polymer are presented. In particular, this article focuses on the shrinkage behavior and the development of stresses under restrained shrinkage conditions. A one‐dimensional numerical model, which is essentially a modification of Zener's standard linear solid model, is presented with the aim of simulating aspects of behavior of particular relevance to tendons within the composite material system. The model comprises a temperature‐dependent dashpot and spring in parallel with a spring and thermal expansion element. The temperature‐dependent functions are calibrated with the obtained data, and a final validation example that shows good accuracy in comparison with experimental data not used for the calibration is presented. © 2010 Wiley Periodicals, Inc.

Synthesis of polylactide with varying molecular weight and aliphatic content: Effect on moisture sorption
Authors: Singh Vishesh M. , Koo Donghun , Palmese Giuseppe R. , Cairncross Richard A.
Published: December 2010

Polylactide (PLA) is a bio‐based, biodegradable polymer, which is derived from lactic acid and has numerous potential applications, some of which are limited by its moisture barrier and thermal properties. Prior studies have been inconsistent about how moisture sorption in PLA varies with crystallinity and molecular weight. This research is a systematic study of how moisture sorption in PLA depends on molecular weight and aliphatic content via end‐group modification. PLA with varying aliphatic content was synthesized by ring‐opening polymerization of L‐lactide initiated with different long‐chain aliphatic alcohols. The terminating end groups were also modified from hydroxyl to acetoxy to eliminate hydrophilic end groups. Molecular weight was controlled by varying the ratio of L‐lactide monomer to alcohol initiator, and triethylaluminum was used as the catalyst for precise control over molecular weight. The molecular weight and end‐group compositions were verified by gel permeation chromatography and nuclear magnetic resonance. Moisture sorption of the modified PLA samples was measured with a quartz crystal microbalance. Quartz crystal microbalance experiments revealed that both molecular weight and aliphatic content contributed to the sorption properties of PLA. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Authors: Jung Kang‐Min , Chun Byung‐Hee , Park Sun Hee , Lee Chang Hun , Kim Sung Hyun
Published: December 2010

In this study, polymethacrylate polymers were synthesized by free‐radical polymerization for use as pour point depressants in lubricant oil, and their low‐temperature properties were investigated. Four methacrylate monomers were synthesized by the esterification of methyl methacrylate (MMA) with four kinds of fatty alcohols. The purification step was performed to prepare the pure monomers. Two polymerization experiments were carried out with four kinds of methacrylate monomers obtained previously and MMA. Copolymers, which were made from one kind of monomer and MMA, and terpolymers, which were made from two kinds of monomers and MMA, were prepared. The molecular structures of the synthesized methacrylate monomers and polymethacrylate polymers were verified by 1H‐NMR, and the molecular weight data were obtained by gel permeation chromatography. The pour points of the base oils containing 0.1 wt % polymethacrylate polymers were measured according to ASTM D 97‐93. The pour points of most base oils containing each polymer decreased compared to that of the pure base oil. Particularly, poly(dodecyl methacrylate‐co‐hexadecyl methacrylate‐co‐methyl methacrylate), made of dodecyl methacrylate, hexadecyl methacrylate, and MMA at a molar ratio of 3.5 : 3.5 : 3, showed the best low‐temperature properties. This terpolymer dropped the pour point of the base oil by as much as 23°C, and its yield was 93.5%. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Effect of surface treatments on the thermal behavior and tensile strength of piassava (Attalea funifera) fibers
Authors: d'Almeida A. L. F. S. , d'Almeida J. R. M. , Barreto D. W. , Calado V.
Published: December 2010

Piassava (Attalea funifera) fibers subjected to several surface chemical treatments and as‐received raw fibers were compared with respect to their thermal and tensile behaviors. The thermal degradation of the raw fibers was characterized by three main stages that corresponded to water release at low temperatures, decomposition of hemicellulose, and decomposition of α cellulose. Mercerization acted mainly on hemicellulose removal, and there was no change in the hydrophilic behavior of the fibers. The removal of hemicellulose split the fibers into microfibrils and favored the thermal decomposition of α cellulose. The same behavior was observed when the fibers were subjected to mercerization and acetylation. The fibers subjected to only acetylation showed thermal behavior similar to that of the raw fibers. With the acetylation treatment, a minor decrease in the hydrophilic character of the fibers was noted. Despite some differences in the thermal behavior, the tensile strengths of the raw and treated fibers were statistically equal. Complementary Fourier transform infrared and scanning electron microscopy analysis corroborated the thermogravimetric analysis/differential thermogravimetry results. © 2010 Wiley Periodicals, Inc.

Authors: Wu Guoliang , Chen Zhongming , Zeng Songjun , Yu Puren , Xie Yanyan , Xiong Yuanqin , Xu Weijian
Published: December 2010

The grafted copolymer (SBS‐g‐MBP) with different grafting ratio, synthesized by our laboratory, was irradiated by ultraviolet (UV) radiation with different time. The structure of SBS‐g‐MBP before and after UV exposure was characterized by Fourier transform infrared spectrometer, and the results confirmed that the UV‐crosslinked structure was formed. The gel fraction before and after UV exposure was discussed, and the results indicated that the gel fraction increased with both exposure time and grafting ratio, and it also indicated the gel fraction was affected mainly by the exposure time. Furthermore, the results of scanning electron microscopy showed that the mode of fracture surfaces transmitted gradually from tough fracture to brittle fracture. The differential scanning calorimetry and thermal gravimetric analyzer indicated that the crosslinking has taken place in the polybutadiene block, and the thermal property was improved after UV exposure. © 2010 Wiley Periodicals, Inc.

Authors: Zhang Quanchao , Zhang Yijia , Wei Qiang , Wang Xiaojun , Liu Jing , Yang Jie , Zhao Changsheng
Published: December 2010

Polyethersulfone (PES) porous microspheres were prepared via electrospraying technique, and then were used for the removal of endocrine disrupters from aqueous solutions. The surface and the internal structures of electrosprayed microspheres were characterized by scanning electron microscopy (SEM) and the results showed that they were porous. The electrosprayed porous PES microspheres can remove biphenyl A and biphenyl effectively. At the same time, they showed larger adsorption capacity and fast kinetics of uptaking target species than PES injected spheres reported in the earlier publications. The hydrophilicity and porosity of electrosprayed microspheres can be controlled by changing the amount of hydrophilic polyethylene glycol (PEG), which influences the adsorption properties of the microspheres. The results showed that electrosprayed porous PES microspheres have the potential to be used in the environmental application. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Authors: Natali Maurizio , Monti Marco , Kenny Josè , Torre Luigi
Published: December 2010

In this research the possibility to produce nanosilica/phenolic nanocomposites by means of a simple low labor cost mechanical approach was investigated. A commercial compatibilized nanosilica was selected as a filler and a resol diluted in methanol as a matrix. The morphology of the produced nanocomposites were studied by means of Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), whereas thermogravimetric analysis (TGA) was used to study the thermal stability of the nanocomposites. The post burning morphology of samples was also investigated. A rheological characterization was also carried out. The results of such study showed that it was possible to obtain a good degree of dispersion and distribution of the nanosilica particles, indicating that the proposed process could be successfully adopted as an alternative approach to sol‐gel techniques. Thermogravimetric analyses showed that all the produced nanocomposites exhibited a better thermal stability than the pristine matrix. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Foramen Magnum Ontogeny inHomo sapiens: A Functional Matrix Perspective
Authors: Richards Gary D. , Jabbour Rebecca S.
Published: December 2010

Historically, the foramen magnum (FM) has been an integral component of studies on skull ontogeny and evolutionary transformations of cranial form. Although this foramen has been considered a single entity, we hypothesize that it comprises two functional matrices, a ventral matrix and a dorsal matrix. In general, the ventral matrix is related to locomotor functions, whereas the dorsal matrix is related to neurological functions and fluid flow dynamics. To test our hypothesis, we used a large ontogenetic sample of modern human crania (seventh fetal month to adult) to (1) delineate bony size and shape ontogeny for both the foramen and its dorsal and ventral units; (2) delineate the role of synchondroses in the observed growth patterns and rates; and (3) explore the relationship between FM and cranial size, shape, and growth. Detailed growth patterns and rates are established for the bony FM and its ventral and dorsal skeletal units. These data are supplemented by literature and observational data on embryonic and fetal FM ontogeny, soft tissue relationships, anomalous/pathological extremes of size, and craniocervical anatomy and locomotor functions. The hypothesis that the FM is composed of a ventral and a dorsal functional matrix is supported by observed ontogenetic differences between ventral and dorsal skeletal units, as well as by the soft tissue anatomy of these matrices. Further documentation of these matrices has the potential to significantly enhance our understanding of the ontogenetic and evolutionary transformations of skull base morphology.

Published: December 2010

Moose (Alces alces) appear to be different from most other cervids in that a well‐developed metatarsal splint bone is present. It is found apposed to the plantolateral portion of the cannon bone in over 70 % of adults. It averages 3.3 mm in width and extends about 22% of the total length of the metatarsal. It may be derived through calcification of connective tissue or by elongation of the vestigial metatarsal V. Anat Rec, 2011. © 2010 Wiley‐Liss, Inc.
Synthetic Studies of the Zoanthamine Alkaloids: Total Synthesis of Zoanthenol Based on an Isoaromatization Strategy
Authors: Yoshimura Fumihiko , Takahashi Yu , Tanino Keiji , Miyashita Masaaki
Published: December 2010

The total synthesis of zoanthenol, a unique aromatic member of the zoanthamine alkaloids, which has exhibited potent anti‐platelet activities on human platelet aggregation, is described in full detail. The key step involves a Brønsted acid‐promoted isoaromatization in the AB ring system to install the crucial aromatic ring. We have not only succeeded in the first total synthesis of zoanthenol, but also established an alternative efficient synthetic route from the commercially available norzoanthamine hydrochloride to zoanthenol.
Robust attitude and vibration control of a nonlinear flexible spacecraft
Authors: Malekzadeh Maryam , Naghash Abolghasem , Talebi H. A.
Published: December 2010

In this paper, the problem of attitude control of a three dimension nonlinear flexible spacecraft is investigated. Two nonlinear controllers are presented. The first controller is based on dynamic inversion, while the second approach is composed of dynamic inversion and µ‐synthesis schemes. It is assumed that only three torques in three directions on the hub are used. Actuator saturation is also considered in the design of controllers. To evaluate the performance of the proposed controllers, an extensive number of simulations on a nonlinear model of the spacecraft are performed. The performances of the proposed controllers are compared in terms of nominal performance, robustness to uncertainties, vibration suppression of panel, sensitivity to measurement noise, environmental disturbance and nonlinearity in large maneuvers. Simulation results confirm the ability of the proposed controller in tracking the attitude trajectory while suppressing the panel vibration. It is also verified that the perturbations, environment disturbances and measurement errors have only slight effects on the tracking and suppression performances.

Screening of cellulases for biofuel production: Online monitoring of the enzymatic hydrolysis of insoluble cellulose using high‐throughput scattered light detection
Authors: Jäger Gernot , Wulfhorst Helene , Zeithammel Erik U. , Elinidou Efthimia , Spiess Antje C. , Büchs Jochen
Published: December 2010

A new prospective cellulase assay simultaneously combining high‐throughput, online analysis and insoluble cellulosic substrates is described. The hydrolysis of three different insoluble cellulosic substrates, catalysed by a commercial cellulase preparation from Trichoderma reesei (Celluclast), was monitored using the BioLector – allowing online monitoring of scattered light intensities in a continuously shaken microtiter plate. Cellulase activities could be quantitatively assayed using the BioLector. At low cellulase/cellulose ratios, the Michaelis‐Menten parameters of the cellulase mixture were mainly affected by the crystallinity index of the cellulose. Here, the apparent maximum cellulase activities inversely correlated with the crystallinity index of the cellulose. At high cellulase/cellulose ratios the particle size of the cellulose, defining the external surface area accessible to the cellulases, was the key determining factor for cellulase activity. The developed technique was also successfully applied to evaluate the pH optimum of cellulases. Moreover, the non‐hydrolytic deagglomeration of cellulose particles was investigated, for the first time, using high‐throughput scattered light detection. In conclusion, this cellulase assay ideally links high‐throughput, online analysis and realistic insoluble cellulosic substrates in one simple system. It will considerably simplify and accelerate fundamental research on cellulase screening.

Understanding the structural basis of protein redox activity is still an open question. Hence, by using a structural genomics approach, different albumins have been chosen to correlate protein structural features with the corresponding reaction rates of thiol exchange between albumin and disulfide DTNB. Predicted structures of rat, porcine, and bovine albumins have been compared with the experimentally derived human albumin. High structural similarity among these four albumins can be observed, in spite of their markedly different reactivity with DTNB. Sequence alignments offered preliminary hints on the contributions of sequence‐specific local environments modulating albumin reactivity. Molecular dynamics simulations performed on experimental and predicted albumin structures reveal that thiolation rates are influenced by hydrogen bonding pattern and stability of the acceptor C34 sulphur atom with donor groups of nearby residues. Atom depth evolution of albumin C34 thiol groups has been monitored during Molecular Dynamic trajectories. The most reactive albumins appeared also the ones presenting the C34 sulphur atom on the protein surface with the highest accessibility. High C34 sulphur atom reactivity in rat and porcine albumins seems to be determined by the presence of additional positively charged amino acid residues favoring both the C34 S− form and the approach of DTNB. © 2010 Wiley Periodicals, Inc.

Background

Ideally, intraoperative sentinel lymph node (SLN) analysis in breast cancer should be automated, have high concordance with extensive histopathology, and be applicable in any hospital setting. A prospective multicentre evaluation of the one-step nucleic acid amplification (OSNA) automated molecular diagnostic system of SLN analysis was undertaken.

Methods

Intraoperative examination of SLNs from 204 patients with breast cancer was performed by OSNA at four sites in the UK. Half of each SLN was assessed by OSNA (for cytokeratin 19 mRNA) and the remaining half was paraffin embedded for intensive histological examination at ten levels. Discordant cases were reanalysed by further molecular biological techniques and by additional histological examination of all remaining nodal material to ascertain whether the discordance was due to an uneven distribution of metastases, known as tissue allocation bias (TAB).

Results

After exclusion of samples affected by TAB, the overall concordance rate for OSNA versus histopathology was 96·0 per cent, with a sensitivity of 91·7 per cent and a specificity of 96·9 per cent. The median time to process a single SLN was 32 (range 22–97) min, and that for two nodes 42 (30–73) min.

Conclusion

OSNA enables accurate automated intraoperative diagnosis and can be used successfully in different UK hospitals. When the SLN is shown to be positive, the patient can undergo immediate axillary clearance under the same anaesthetic rather than having a delayed second procedure.
