Controllability results for cascade systems of $m$ coupled parabolic PDEs by one control force
Authors: González-Burgos Manuel , de Teresa Luz
Published: February 2010

In this paper we will analyze the controllability properties of a linear coupled parabolic system of

m

equations when a unique distributed control is exerted on the system. We will see that, when a cascade system is considered, we can prove a global Carleman inequality for the adjoint system which bounds the global integrals of the variable

φ = (φ_1, …, φ_m)^*

in terms of a unique localized variable. As a consequence, we will obtain the null controllability property for the system with one control force.

Medicina y salud en la prensa. Las noticias de salud en los principales diarios de Galicia
Authors: Costa Sánchez Carmen
Published: February 2010

El presente trabajo tiene como objeto de estudio la información sobre salud y medicina publicada a lo largo de una semana en los cuatro diarios de mayor difusión de Galicia. El periodismo tiene la responsabilidad de informar en esta materia según criterios de calidad, en lugar de considerar la salud un tema secundario, anecdótico y de relleno, tratándolo de modo superficial. El nacimiento de las secciones específicas junto a la incorporación de los periodistas especializados en salud en las redacciones de las principales cabeceras generalistas españolas están iniciando un proceso de profundización a este respecto. Pero, ¿qué ocurre en la prensa autonómica? ¿Cuál es el tratamiento informativo que recibe la información sobre salud y medicina en la prensa diaria de Galicia? Aspectos descriptivos, cuantitativos y de análisis de contenido nos permitirán conocer y reflexionar en torno a la cobertura informativa que se realiza de estos hechos noticiosos con objeto de diagnosticar la situación y plantear las mejoras necesarias.
Surprising performance of alginate beads for the release of low‐molecular‐weight drugs
Authors: Elnashar Magdy M. , Yassin Mohamed A. , Abdel Moneim Abou El‐Fetouh , Abdel Bary Elsayed M.
Published: February 2010

The model of low‐molecular‐weight drugs has been encapsulated within alginate beads hardened with calcium chloride. The drug's release kinetic using 3% (w/v) alginate has shown a surprising behavior after 2 h, where the release kinetic was shifted from Fickian to case II transport mechanism contradicting other authors like Akihiko et al. (J Control Release 1999, 58, 21). To support this finding, we studied the swelling of dried gel beads of 2 and 3% (w/v) alginate, which showed a sudden decrease in the swelling of 3% (w/v) alginate after 2 h due to a partial bursting of the beads. This sudden bursting was clearly observed using the optical microscope to emphasize the new findings. Calcium alginate beads revealed pH sensitivity, where 2% (w/v) alginate beads showed a maximum swelling of 5000% in alkaline medium at pH 7.4, compared with a negligible swelling percent of 60% in acidic medium (pH 1.2). Accordingly, it could be a good candidate for targeting smart and low‐molecular‐weight drugs to the intestine. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Influence of in situ compatibilization on in situ formation of low‐density polyethylene/polyamide 6 blends by reactive extrusion
Authors: Fang Hui , Yang Guisheng
Published: February 2010

Low‐density polyethylene/polyamide 6 (LDPE/PA6) blends were in situ formed by reactive extrusion, in which in situ polymerization of ε‐caprolactam (CL) and in situ copolymerization of maleic anhydride grafted low‐density polyethylene (LDPE‐MA) and CL took place simultaneously. The latter reaction could be considered as in situ compatibilization, and the influence of in situ compatibilization on the morphologies, thermal properties, and rheological behaviors of the blends was investigated in this work. Scanning electron microscopy showed that the in situ compatibilization could dramatically reduce the dispersed phase sizes and narrow the size distribution. The thermal properties indicated that in differential scanning calorimetry (DSC) cooling scans, fractionated crystallization of the PA6 component was observed in all cases and was promoted with increasing the amount of LDPE‐MA. The DSC second heating scans showed the in situ compatibilization could stimulate the formation of the less stable γ‐crystalline form of PA6 in the blends. Dynamic rheological experiments revealed the in situ compatibilization had enhanced the viscosity, storage modulus, and loss modulus of the blend and reduce the corresponding slope values of the storage modulus and loss modulus. © 2010 Wiley Periodicals, Inc.

Study on properties of a novel photosensitive polysiloxane urethane acrylate for solder mask
Authors: Sun Fang , Jiang Shengling
Published: February 2010

The photosensitive and physical and mechanical properties of a novel polysiloxane urethane acrylate (PSUA) for solder mask were investigated using real‐time FTIR, DMTA and TGA. It is noted that PSUA showed a notable photosensitivity and a good compatibility with the acrylic monomers and resins. PSUA cured film exhibited excellent thermal property, tensile strength and toughness, and chemical resistance. The decomposition temperature of PSUA was 402 °C. Thermal weight losses of pure PSUA cured film at 300 °C were only 5%. Elongation percentage of PSUA cured film was up to 59%. PSUA resin can be used for solder mask materials for printed circuit. Technology performances of photosensitive imaging flexible solder mask containing PSUA answers operating requirements of the solder masker for printing circuit board. © 2010 Wiley Periodicals, Inc.

Hemodialysis membrane prepared from cellulose/N‐methylmorpholine‐N‐oxide solution. IV. Comparative studies on the surface morphology of membranes prepared from N‐methylmorpholine‐N‐oxide and cuprammonium solutions
Authors: Abe Yoshihiko , Mochizuki Akira
Published: February 2010

The surface morphology of regenerated cellulose membranes prepared by casting cellulose/N‐methylmorpholine‐N‐oxide (NMMO) and cuprammonium solutions onto a glass plate (denoted NMMO membrane and cuprammonium membrane, respectively) were studied by using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The concentration of cellulose in the casting solution was 8 wt %. The SEM images of the surfaces of both membranes indicated that they had aggregate structures formed by cellulose particles (10–150 nm in diameter). In the NMMO membrane, the glass‐side surface was composed of larger particles and was rougher than the air‐side surface. However, in the cuprammonium membrane there was little structural difference between air‐side and glass‐side surfaces. The AFM images showed that all surfaces were rough due to the cellulose particles. As for the NMMO membrane, the difference in the surface structure between the air‐side and the glass‐side was the same as observed by SEM. AFM also indicated that the order of the surface roughness was as follows: glass‐side of NMMO membrane > air‐side of NMMO membrane > air‐side of cuprammonium membrane ≅ glass‐side of cuprammonium membrane. On the basis of these results observed for both membranes, the reason for the difference in the performances of NMMO and cuprammonium membranes is discussed from the viewpoint of surface structure. © 2010 Wiley Periodicals, Inc.

Computer simulation and experimental implementation of a PIC‐controlled hybrid multilevel inverter for undergraduate laboratories
Authors: Saribulut Lütfü , Teke Ahmet , Meral M. Emin , Tümay Mehmet
Published: February 2010

Hybrid multilevel inverters have emerged as attractive power conversion systems at medium voltage levels, which are structured by cascaded series inverters having different internal DC bus voltages. This scheme therefore provides the capability to produce higher voltages at higher speeds with low switching losses and high conversion efficiency. The fundamentals and importance of hybrid multilevel systems can be easily enhanced by the undergraduate with visual learning and laboratory studies. However, the students cannot be able to implement the peripheral interface controller (PIC)‐based projects sufficiently. In this paper, the simulation models and experimental setup of a hybrid multilevel inverter are presented in detail. From the theoretical and experimental experience obtained from this study, the students and engineers can provide more analytical opportunities for studying control algorithms of PIC controlled power electronics projects. This will provide the students to reinforce their lectures and laboratory studies. © 2010 Wiley Periodicals, Inc. Comput Appl Eng Educ 20: 445–453, 2012
Copper(II) Complexes of a Hexadentate Mixed‐Donor N3S3 Macrobicyclic Cage: Facile Rearrangements and Interconversions
Authors: Bell Craig A. , Bernhardt Paul V. , Gahan Lawrence R. , Martínez Manuel , Monteiro Michael J. , Rodríguez Carlos , Sharrad Clint A.
Published: February 2010

The potentially hexadentate mixed‐donor cage ligand 1‐methyl‐8‐amino‐3,13,16‐trithia‐6,10,19‐triazabicyclo[6.6.6]eicosane (AMME‐N3S3sar; sar=sarcophagine) displays variable coordination modes in a complex with copper(II). In the absence of coordinating anions, the ligand adopts a conventional hexadentate N3S3 binding mode in the complex [Cu(AMME‐N3S3sar)](ClO4)2 that is typical of cage ligands. This structure was determined by X‐ray crystallography and solution spectroscopy (EPR and NIR UV/Vis). However, in the presence of bromide ions in DMSO, clean conversion to a five‐coordinate bromido complex [Cu(AMME‐N3S3sar)Br]+ is observed that features a novel tetradentate (N2S2)‐coordinated form of the cage ligand. This copper(II) complex has also been characterized by X‐ray crystallography and solution spectroscopy. The mechanism of the reversible interconversion between the six‐ and five‐coordinated copper(II) complexes has been studied and the reaction has been resolved into two steps; the rate of the first is linearly dependent on bromide ion concentration and the second is bromide independent. Electrochemistry of both [Cu(AMME‐N3S3sar)]2+ and [Cu(AMME‐N3S3sar)Br]+ in DMSO shows that upon reduction to the monovalent state, they share a common five‐coordinated form in which the ligand is bound to copper in a tetradentate form exclusively, regardless of whether a six‐ or five‐coordinated copper(II) complex is the precursor.

Indirubin is an active constituent of traditional Chinese preparations used for the treatment of chronic myelocytic leukemia (CML). In the present study, the inhibitory activity of indirubin and its derivatives toward Fms‐like tyrosine kinase 3 (FLT3) was examined. Indirubin‐3′‐oxime (IO) and 6‐bromoindirubin‐3′‐oxime (BIO) had potent inhibitory activity against FLT3 (IC50=79 nM and 254 nM, respectively). We also tested the cytotoxicity of these compounds against acute myeloid leukemia cell lines: MV4;11 cells harboring a constitutively activated form of FLT3, and RS4;11 cells with wild‐type FLT3. IO and BIO potently inhibited the growth of MV4;11 cells with IC50 values of 30 nM and 61 nM, respectively. Conversely, RS4;11 cells were far less sensitive to these compounds. IO arrested the cell cycle of MV4;11 cells at the G1 phase, and increased the dead cell population at the sub‐G1 phase and annexin V‐positive cells. From these results, derivatives of IO may have potential to be developed as anti‐leukemic agents. Drug Dev Res 71: 221–227, 2010. © 2010 Wiley‐Liss, Inc.
Varying Bonding Modes of the Zintl Ion [Ge9]4– in CuI Complexes: Syntheses and Structures of [Cu(η4‐Ge9)(PR3)]3– (R = iPr, Cy) and [Cu(η4‐Ge9)(η1‐Ge9)]7–

Three novel Cu‐capped Ge9 clusters were synthesized from K4Ge9 and phosphane‐stabilized copper(I) compounds CuCl(PR3) with R = isopropyl (iPr) or cyclohexyl (Cy). Reactions in N,N‐dimethylformamide (dmf) at ambient temperature resulted in the isolation of [Cu(η4‐Ge9)(PCy3)]3– as a [K([2.2]crypt)] salt ([2.2]crypt: 1,7,10,16‐tetraoxa‐4,13‐diazacyclooctadecane). From solutions of [Cu(η4‐Ge9)(PiPr3)]3– in liquid ammonia, the anion was isolated when the reaction mixture was stored at –70 °C. Under the same reaction conditions but at a temperature of –40 °C the cluster [Cu(η4‐Ge9)(η1‐Ge9)]7– crystallized in the presence of [2.2.2]crypt(4,7,13,16,21,24‐hexaoxa‐1,10‐diazabicyclo[8.8.8]hexacosan)or [2.2]crypt. The ligand‐free intermetalloid cluster [Cu(η4‐Ge9)(η1‐Ge9)]7– is a unique example in which two differently bonded Ge9 units are linked by a transition‐metal atom. This cluster complex remarkably demonstrates the ability of homoatomic polyanions to bind in different modes to the same transition‐metal atom. One Ge9 nido cluster binds to the copper atom by means of its open square face, whereas the second Ge9 nido cluster is coordinated through one lone pair as a two‐electron σ donor. The key role of the flexible electron‐donor properties of [Ge9]4– in the reaction path towards the formation of intermetalliod clusters is discussed.
Estimating the effect of a gasoline tax on carbon emissions
Authors: Davis Lucas W. , Kilian Lutz
Published: February 2010

Recently the proposal has been made to raise gasoline taxes in the United States to curb carbon emissions. The existing literature on the sensitivity of gasoline consumption to changes in price may not be appropriate for evaluating the effectiveness of such a tax. First, most of these studies fail to address the endogeneity of gasoline prices. Second, the responsiveness of gasoline consumption to a change in tax may differ from the responsiveness of consumption to an average change in price. We address these challenges using a variety of methods including traditional single‐equation regression models, estimated by least squares or instrumental variables methods, and structural vector autoregressions. Our preferred approach exploits the historical variation in US federal and state gasoline taxes. Our most credible estimates imply that a 10‐cent per gallon increase in the gasoline tax would reduce carbon emissions from vehicles in the United States by about 1.5%.

Published: February 2010

The expression of glutathione S‐transferase (GST) is a crucial factor in determining the sensitivity of cells and organs in response to a variety of toxicants. In this study, we cloned the core nucleotide of alpha, kappa, mu, mGST, pi, rho, and theta‐like GST genes from bighead carp (Aristichthys nobilis). Their derived amino acid sequences were clustered with other vertebrate GSTs in a phylogenetic tree, and the bighead carp GST sequences have the highest similarity with those from common carp and zebrafish. We quantified the constitutive mRNA transcription of GST isoforms in eight different tissues (liver, kidney, spleen, intestine, muscle, heart, brain, and gill). The information obtained from the present study could be distilled into a few generalized principles: multiple GST isoenzymes were ubiquitously expressed in all tissues; majority of GSTs had high constitutive expression in intestine, liver, and kidney. These findings are in agreement with the roles of these tissues in xenobiotic metabolism. At the same time, some unique findings were detected in the current experiment: (1) higher expression of most GSTs was observed in spleen; (2) the expression of GST pi was highest in almost all the studied tissues except muscle; the other two isoforms, GST alpha and rho, were also highly expressed in liver, kidney, intestine, spleen, heart, and brain of bighead carp. All these results strongly imply an important role of these GST isoforms in detoxification of ingested xenobiotics. © 2010 Wiley Periodicals, Inc.

Published: February 2010

In this study, we determined whether p53 expression affected the sensitivity of non–small cell lung cancer (NSCLC) and colon cancer cells to bleomycin (BLM). Two human NSCLC cell lines (A549 expressing wild‐type p53 and p53‐null H1299) and two colon cancer cell lines (HCT116 p53+/+ and its p53 deficient subline HCT116 p53−/−) were subjected to treatment with BLM. Cells were treated with various concentrations of BLM, and cellular viability was assessed by formazan assay. To investigate the role of p53 in BLM sensitivity, we transduced cells with adenovirus with wild‐type p53, dominant‐negative p53, and GFP control, and analyzed the effect on cellular viability. Cells expressing wild‐type p53 were more sensitive to BLM than p53‐null cells in both NSCLC and colon cancer cells. Sensitivity to BLM of the cells with wild‐type p53 was reduced by overexpression of dominant‐negative p53, while BLM sensitivity of p53‐null cells was increased by wild‐type p53 in both NSCLC cells and colon cancer cells. In conclusion, our data show that p53 sensitizes all four cancer cells lines tested to BLM toxicity and overexpression of p53 confers sensitivity to the cytotoxic activity of the anticancer agent in p53‐null cells. © 2010 Wiley Periodicals, Inc.

How MetLife balances effective organization design with the need for speed in postacquisition integration
Authors: Jasinski Thomas J.
Published: February 2010

This case study demonstrates that good design and speed to integration can coexist—and, more important, are interdependent levers for achieving the near‐term goals and the longer‐term value of mergers and acquisitions (M&As). The author presents the Organization Effectiveness team's operating model, MetLife's organizational design framework and process, and its alignment with Human Resources' approach to M&As. He then describes MetLife Bank's rapid acquisition of two firms, and the two‐stage organizational design that facilitated the transition. The initial structure preserved business effectiveness, while the combined leadership team clarified longer‐term vision, strategy, and desired organizational capabilities, which led to a second organizational structure nine months later to achieve the efficiencies and benefits of scale and build the capabilities that create competitive advantage for MetLife Bank. © 2010 Wiley Periodicals, Inc.
Transfer or adapt business practices internationally? Some answers from Southeast Asia
Authors: Hipsher Scott A.
Published: February 2010

International organizations have long been torn between transferring their existing practices into new locations or adapting to local conditions. A major miscalculation can have extremely negative consequences for companies as they expand internationally. An examination of business practices in the Theravada Buddhist countries of Southeast Asia illustrates how breaking down business practices into their strategic, tactical, and operational levels may provide a useful guide for setting up initial operations in a foreign environment. It is proposed that strategic principles can be transferred but strategic practices should adapt to local conditions; tactical‐level business practices will generally need to adapt to the local environment, while it is likely that best practices at the operational level can be transferred across international borders with little need to adapt to local conditions. © 2010 Wiley Periodicals, Inc.

Published: February 2010

The aim of this study was to determine if extracorporeal shock wave therapy (ESWT) in vivo affects the structural integrity of articular cartilage. A single bout of ESWT (1500 shock waves of 0.5 mJ/mm2) was applied to femoral heads of 18 adult Sprague–Dawley rats. Two sham‐treated animals served as controls. Cartilage of each femoral head was harvested at 1, 4, or 10 weeks after ESWT (n = 6 per treatment group) and scored on safranin‐O‐stained sections. Expression of tenascin‐C and chitinase 3‐like protein 1 (Chi3L1) was analyzed by immunohistochemistry. Quantitative real‐time polymerase chain reaction (PCR) was used to examine collagen (II)α1 (COL2A1) expression and chondrocyte morphology was investigated by transmission electron microscopy no changes in Mankin scores were observed after ESWT. Positive immunostaining for tenascin‐C and Chi3L1 was found up to 10 weeks after ESWT in experimental but not in control cartilage. COL2A1 mRNA was increased in samples 1 and 4 weeks after ESWT. Alterations found on the ultrastructural level showed expansion of the rough‐surfaced endoplasmatic reticulum, detachment of the cell membrane and necrotic chondrocytes. Extracorporeal shock waves caused alterations of hyaline cartilage on a molecular and ultrastructural level that were distinctly different from control. Similar changes were described before in the very early phase of osteoarthritis (OA). High‐energy ESWT might therefore cause degenerative changes in hyaline cartilage as they are found in initial OA. © 2010 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Published: February 2010

The objective of this study was to evaluate the effects of local endothelial progenitor cell (EPC) therapy on bone regeneration in a rat model. A segmental bone defect (5 mm) was created in the femur and fixed with a mini‐plate. There were two groups: EPC‐treated (N = 28) and control (N = 28). Seven animals were sacrificed from each group at 1, 2, 3, and 10 weeks postoperatively. Healing of the defect was evaluated with radiographic, histological, and quantitative micro‐computed tomography (micro‐CT) scans. Radiographically, mean scores of the EPC and control groups were, respectively, 1.16–0.61 (p < 0.05) at 1 week, 2.53–1.54 (p < 0.05) at 2 weeks, and 4.58–2.35 at 3 weeks (p < 0.05). At 10 weeks, all the animals in the EPC‐treated group had complete union (7/7), but in the control group none achieved union (0/7). Histological evaluation revealed that specimens from EPC‐treated animals had abundant new bone and vessel formation compared to that in controls. Micro‐CT assessment of the samples from the animals sacrificed at 10 weeks (N = 14) showed significantly improved parameters of bone volume (36.58–10.57, p = 0.000), bone volume density (0.26–0.17, p = 0.000), model index −2.22–2.79, p = 0.000), trabecular number (1.28–0.91, p = 0.063), trabecular thickness (0.21–0.15, p = 0.001), trabecular spacing (0.63–1.07, p = 0.022), bone surface (353.75–152.08, p = 0.000), and bone surface to bone volume ratio (9.54–14.24, p = 0.004) for the EPC group compared to control, respectively. In conclusion, local EPC therapy significantly enhanced bone regeneration in a segmental defect model in rat femur diaphysis. © 2010 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Published: February 2010

A novel method, HPLC‐MS/MS was developed to qualitatively identify and quantitatively determine the 28 components including 19 diterpenoids, 6 phenolic acids and 3 flavonoids in Isodon rubescens, an important traditional Chinese medicine. The separation was performed on a C18 column with linear gradient elution with 0.1% aqueous formic acid/methanol containing 0.1% formic acid at a flow rate of 0.7 mL/min. The identification and quantification of those analytes were achieved on a hybrid quadrupole linear ion trap mass spectrometer. Multiple‐reaction monitoring scanning was employed for quantification with switching electrospray ion source polarity between positive and negative modes in a single run. Full validation of the method was carried out (linearity, precision, accuracy, LOD and LOQ). The results indicated that the method was simple, rapid, specific and reliable. The proposed method was successfully applied for the qualitative and quantitative analysis of 28 chemical compositions in 21 batchs of natural and cultured I. rubescens samples from different sources which had great variation on the contents. The results demonstrated that the method was useful for standardization and differentiation of large numbers of similar samples.
Predeployment gender differences in stressors and mental health among U.S. National Guard troops poised for Operation Iraqi Freedom deployment

Published: February 2010

Increased exposure of women soldiers to combat in current conflicts heightens interest in the question of whether risk and resilience factors differ for female and male military personnel prior to deployment. The authors examined this question in a panel of 522 National Guard soldiers (462 men and 60 women) poised for deployment to Iraq. Soldiers completed a battery of self‐report measures, including the PTSD Checklist, Beck Depression Inventory‐II, and scales from the Deployment Risk and Resilience Inventory. Modest differences were observed between women and men on predeployment risk factors and some risk‐related correlations with PTSD and depression measures; however, gender did not moderate the associations between hypothesized risk/resilience factors and baseline mental health. Implications for interventions and future research are discussed.
