Metallfreie organische Farbstoffe für farbstoffsensibilisierte Solarzellen – von Struktur‐Eigenschafts‐Beziehungen zu Designregeln (2009)

Abstract Es geht auch ohne Ru: Farbstoffsensibilisierte Solarzellen, die metallfreie organische Farbstoffe enthalten, wurden in den vergangenen Jahren entscheidend verbessert. Mittlerweile haben sich verschiedene Strategien bei der Konstruktion der Farbstoffe etabliert. In diesem Aufsatz werden Struktur‐Eigenschafts‐Effizienz‐Beziehungen aus der Vielzahl publizierter Farbstoffe abgeleitet, die dabei helfen sollen, hocheffiziente Sensibilisatoren zu entwerfen. magnified image Farbstoffsensibilisierte Solarzellen (dye‐sensitized solar cells, DSSCs) haben in den letzten Jahren beachtliche Aufmerksamkeit auf sich gezogen, weil sie eine Möglichkeit zur kostengünstigen Produktion von Solarenergie darstellen. In diesem Aufsatz konzentrieren wir uns auf aktuelle Fortschritte bei der Entwicklung von funktionellen metallfreien Farbstoffen und deren Anwendung in farbstoffsensibilisierten Solarzellen mit unterschiedlichen Elektrolytsystemen. Ebenso wird die Cosensibilisierung, eine Technik zur Erweiterung des Absorptionsbereichs, als eine Möglichkeit erläutert, die Leistungsfähigkeit von Solarzellen zu verbessern. Zusätzlich berichten wir über invertierte Farbstoffe, die in Photokathoden Verwendung finden und damit einen relativ neuen Ansatz für die Herstellung von Tandemzellen darstellen. Besonderer Wert wurde darauf gelegt, Beziehungen zwischen der Molekülstruktur, den daraus resultierenden physikalischen Eigenschaften und der Leistungsfähigkeit in Solarzellen herauszuarbeiten.

Identification of a nitrogenase FeMo cofactor precursor on NifEN complex (2005)

The biosynthesis of the FeMo cofactor (FeMoco) of Azotobacter vinelandii nitrogenase presumably starts with the production of its Fe/S core by NifB (the nifB gene product). This core is subsequently processed on the alpha2beta2 tetrameric NifEN complex (formed by the nifE and nifN gene products). In this article, we identify a NifEN-bound FeMoco precursor form that can be converted to fully assembled FeMoco in a so-called FeMoco-maturation assay containing only purified components. We also establish that only molybdate, homocitrate, MgATP, and Fe protein are essential for FeMoco maturation. The FeMoco-maturation assay described here will further address the remaining questions related to the assembly mechanism of the ever-intriguing FeMoco.
Localization of ADAMTS13 to the stellate cells of human liver (2005)

Although the chromosomal localization (9q34) of the gene encoding the human form of ADAMTS13 (a disintegrin-like and metalloproteinase with thrombospondin type-1 motifs 13) and its exclusive expression in the liver have been established, the cells that produce this enzyme are yet to be determined. We investigated the expression of ADAMTS13 mRNA and protein in fresh frozen specimens obtained during liver biopsies of 8 patients with liver diseases. In situ hybridizations to localize ADAMTS13 mRNA showed positive signals exclusively in perisinusoidal cells with irregularly elongated dendritic processes extending between hepatocytes. Furthermore, ADAMTS13 was detected immunohistochemically in perisinusoidal cells, whereas no staining was observed in hepatocytes. The positive cells varied in shape from unipolar to dendritic with irregularly elongated cytoplasmic processes, features common to hepatic stellate cells (HSCs). Double-labeling experiments revealed that the ADAMTS13-positive cells also expressed alpha-smooth muscle actin, confirming that these cells were activated HSCs. These results suggest that HSCs may be major cells producing ADAMTS13 in human liver.
Feasibility of transcatheter intervention for severe aortic stenosis in patients ≥90 years of age: Aortic valvuloplasty revisited (2007)

BAV can be carried out in high risk nonagenarian patients with an acceptable complication rate, low perioperative mortality, and early improvement in NYHA functional class.
Soft fault detection in cables using the cluster time-frequency domain reflectometry (2013)

Faced with the continual increase in complexity of wiring networks, their reliability, in particular in embedded fields (such as automotive and aerospace industries) becomes a major issue. In wiring diagnostics, reflectometry methods are commonly used. They are quite efficient for detecting important damage (hard faults) such as short-or open-circuits. These faults can have heavy material (e.g.: fires) and economical consequences. Then detecting them before they happen would be very interesting and useful. Unfortunately no current method is efficient enough for addressing soft faults. This article proposes an original approach to overcome this problem: the Cluster Time-Frequency Domain Reflectometry (CTFDR). Based on the fact that a wire is most often in a bundle with several other wires, this method takes advantage of the resultant near end crosstalk signals to get more information about the state of the wires in the bundle. To make the detection of incipient faults easier, a normalized time-frequency cross correlation function has also been used.
Surface Modification of PMMA to Improve Adhesion to Corneal Substitutes in a Synthetic Core–Skirt Keratoprosthesis (2015)

Patients with advanced corneal disease do poorly with conventional corneal transplantation and require a keratoprosthesis (KPro) for visual rehabilitation. The most widely used KPro is constructed using poly(methyl methacrylate) (PMMA) in the central optical core and a donor cornea as skirt material. In many cases, poor adherence between the PMMA and the soft corneal tissue is responsible for device "extrusion" and bacterial infiltration. The interfacial adhesion between the tissue and the PMMA was therefore critical to successful implantation and device longevity. In our approach, we modified the PMMA surface using oxygen plasma (plasma group); plasma followed by calcium phosphate (CaP) coating (p-CaP); dopamine followed by CaP coating (d-CaP); or plasma followed by coating with (3-aminopropyl)triethoxysilane (3-APTES). To create a synthetic KPro model, we constructed and attached 500 μm thick collagen type I hydrogel on the modified PMMA surfaces. Surface modifications produced significantly improved interfacial adhesion strength compared to untreated PMMA (p < 0.001). The p-CaP group yielded the best interfacial adhesion with the hydrogel (177 ± 27 mN/cm(2)) followed by d-CaP (168 ± 31 mN/cm(2)), 3-APTES (145 ± 12 mN/cm(2)), and plasma (119 ± 10 mN/cm(2)). Longer-term stability of the adhesion was achieved by d-CaP, which, after 14 and 28 days of incubation in phosphate buffered saline, yielded 164 ± 25 mN/cm(2) (p = 0.906 compared to adhesion at day 1) and 131 ± 20 mN/cm(2) (p = 0.053), respectively. In contrast, significant reduction of adhesion strength was observed in p-CaP group over time (p < 0.001). All surface coatings were biocompatible to human corneal stromal fibroblasts, except for the 3-APTES group, which showed no live cells at 72 h of culture. In contrast, cells on d-CaP surface showed good anchorage, evidenced by the expression of focal adhesion complex (paxillin and vinculin), and prominent filopodia protrusions. In conclusion, d-CaP can not only enhance and provide stability to the adhesion of collagen hydrogel on the PMMA surface but also promote biointegration.
Personal computer-music system-song transcription and its application (1988)

A description is given of an easy-to-use computer music system using a personal computer, which can transcribe a song into a music score and generate accompaniment to match the melody. The system consists of a 16 bit personal computer, an A/D (analog to digital) converter, a digital signal processor, a microphone, and a music synthesizer. The sounds of a song being sung or hummed are analyzed for pitch and strength. Then, the melody of the song is extracted using the computer's preprogrammed musical knowledge. After the transcription is completed, a chord progression is determined automatically and three-part accompaniment is generated on the rhythm pattern selected interactively. The melody and generated accompaniment are played together by musical synthesizer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Anonymous Mobile Agents (2006)

One of the most important issues of the agent security is to keep the agent anonymity, not only in regard of the outsider (eavesdropper) but from the visited hosts too. Indeed, the observer may access agent's data, like the agent's route information data, and thus collecting sensitive information about the agent's owner. In this paper, we present a solution based on mixes to hide the itinerary of the agent. We extend the existing agent based Ajanta plateform by adding this functionality. It is then possible to create protected agents capable of roaming in the internet without revealing their whereabouts information.
The state of academic research into sustainability accounting and an enabling research methodology (2012)

This paper takes a critical look into the emergence and establishment of sustainability accounting as an area of research and advocates for a critical theoretical and methodological approach to better understand and beware of the shifting meanings of sustainability (Aras and Crowther, 2009; Kaidonis et al., 2010). In so doing, it hopes to bring to the notice of the sustainability research community, especially those who are novice researchers in this area within our discipline, the opportunities that has been created by the various use of the very word 'sustainability' for rewarding case studies. After taking a 'pulse' of the extant sustainability accounting literature, a critical theoretical and methodological approach has been suggested to enrich understanding of the sustainability issue to be studied so that opportunities can be created for emancipatory change. Critical discourse analysis has been put forward and elaborated as an enabling methodology for a richer and deeper analysis.
Stent implantation to create interatrial communications in patients with complex congenital heart disease (1999)

A restrictive interatrial communication can complicate the management of complex congenital heart disease. The purpose of this report is to present a new technique to achieve a patent and reliable interatrial communication by using an endovascular stent. A stent was successfully implanted across a fenestrated extracardiac conduit in two patients with low cardiac output after Fontan operations and across the interatrial septum in a patient with double inlet left ventricle and severe left atrioventricular stenosis. The procedures were uncomplicated and all patients showed immediate hemodynamic improvement. Cathet. Cardiovasc. Intervent. 47:310–313, 1999. © 1999 Wiley-Liss, Inc.
FRACTURING FLUID (GUAR POLYMER GEL)DEGRADATION STUDY BY USING OXIDATIVE ANDENZYME BREAKER (2011)

Hydraulic fracturing commonly refered to as fracking is a proven technology
to enhance productivity and maximize recovery in oil and gas wells. Hydraulic
fracturing method is ahnost the same as frac pack but differ in term of treatment
purpose. Frac pack is aim for sand control while hydraulic fracturing is to stimulate
the well. The fracturing fluid used in hydraulic fracturing or frac pack contain a
chemical breakers to reduce the viscosity of the fluid intermingled with the proppant.
Chemical breakers reduce viscosity of the guar, polymer by cleaving the polymer into
small-molecular-weight fragments. The reduction of viscosity will facilitates the
flowback of residual polymer providing rapid recovery of polymer from proppant
pack. Ineffective breakers or misapplication of breakers can result in screenouts or
flowback of viscous fluids both of which 9ail significantly decrease the well
productivity.
Breaker activity of low to medium temperature range oxidative and enzyme
breaker systems was evaluated. ViCon NF an oxidative breaker (Halliburton product)
and GBW 12-CD an enzyme breaker (BJ Services product) were used in this project
with the main objective to study on the degradation pattern of fracturing fluid (guar
polymer gel) as a function of time, temperature and breaker concentration itself. This
paper provides a guideline of how to mix the fracturing fluid, the compositions of the
fracturing fluid, and how to conduct the crosslink and break test. Crosslink test gave
the optimum crosslinker concentration to produce good crosslink gel and the break
test gave the characteristic of the gel during degradation process and also the break
time. Besides relying on the laboratory experiment, information obtained from
research on SPE and US Pattern papers were \)Sed to make a comparison study on
oxidative and enzyme breakers properties.
Degradation pattern observed from the break test showed that reduction in gel
viscosity depends on time, temperature, and breaker concentration. Also, for enzyme
breaker, increasing temperature does not mean more reduction in viscosity.
Observation from experiment also revealed that small concentration of enzyme
breakers provides rapid break compare to oxidative breakers.
Animal model of axonal Guillain‐Barré syndrome induced by sensitization with GM1 ganglioside (2001)

Some humans develop the axonal form of Guillain-Barré syndrome after receiving bovine brain ganglioside. On sensitization with the ganglioside mixture, all of a group of rabbits injected developed high anti-GM1 IgG antibody titers, flaccid limb weakness of acute onset, and a monophasic illness course. Pathological findings for the peripheral nerves showed predominant Wallerian-like degeneration, with neither lymphocytic infiltration nor demyelination. IgG was deposited on the axons of the anterior roots, and GM1 was proved to be present on the axons of peripheral nerves. Sensitization with purified GM1 also induced axonal neuropathy, indicating that GM1 was the immunogen in the mixture. A model of human axonal Guillain-Barré syndrome has been established that uses inoculation with a bovine brain ganglioside mixture or isolated GM1. This model may help to clarify the molecular pathogenesis of the syndrome and to develop new treatments for it.
ACORDOS E REGRAS NORTEADORAS DO COMÉRCIO INTERNACIONAL: DA RODADA URUGUAI À POLÍTICA DE COMÉRCIO EXTERIOR BRASILEIRA (2009)

Este trabalho objetiva compreender o cenário norteador do Comércio Internacional após 1986, com a Rodada Uruguai e sua influência na política de Comércio Exterior do Brasil. Investiga-se os principais acordos e regras norteadoras do Comércio Internacional; as ações realizadas no âmbito brasileiro para a política de Comércio Exterior; a relação entre a proposta mundial de comércio e a que, efetivamente, o Brasil realiza. O estudo foi realizado, por meio de levantamento bibliográfico e documental, tomando-se como contexto o Brasil inserido no mercado internacional, delimitado pelo recorte temporal pós-Rodada do Uruguai, realizada entre 1986 e 1994, estendendo-se até o ano de 2006, no que concerne aos reflexos, advindos dessa Rodada de Negociações Internacionais sobre a Política Brasileira de Comércio Exterior. A intensificação dos movimentos de Globalização, de produção e internacionalização dos fluxos de capitais significa um mundo de crescente interdependência econômica entre as nações, cuja regulação tem suscitado questões quanto ao papel reservado ao Estado, condutor dos ditames político-econômicos, frente às instituições internacionais criadas, a partir da Conferência de Bretton Woods em 1944. Do trabalho concluiu-se quais os desafios da política de comércio exterior brasileira para os próximos anos: participação mais atuante no âmbito da Organização Mundial de Comércio, integração do Mercosul na Área de Livre Comércio das Américas e na União Européia. Tais desafios requerem dos atores da sociedade (Governos, Empresas, Trabalhadores) preparação para avaliar os impactos de cada uma das regras do comércio em negociação, não só para as políticas econômicas do país, mas também para o futuro das atividades das empresas.  PALAVRAS-CHAVE: Acordos, Regras, Comércio Internacional e Política.
A Hybrid Frame Concealment Algorithm for H.264/AVC (2009)

In packet-based video transmissions, packets loss due to channel errors may result in the loss of the whole video frame. Recently, many error concealment algorithms have been proposed in order to combat channel errors; however, most of the existing algorithms can only deal with the loss of macroblocks and are not able to conceal the whole missing frame. In order to resolve this problem, in this paper, we have proposed a new hybrid motion vector extrapolation (HMVE) algorithm to recover the whole missing frame, and it is able to provide more accurate estimation for the motion vectors of the missing frame than other conventional methods. Simulation results show that it is highly effective and significantly outperforms other existing frame recovery methods.
Efficient inducible Cre‐mediated recombination in <i>Tcf21</i>cell lineages in the heart and kidney (2011)

Tcf21 is a Class II bHLH family member with essential roles in the formation of the lungs, kidneys, gonads, spleen, and heart. Here, we report the utility of a mouse line with targeted insertion of a tamoxifen-inducible Cre recombinase, MerCreMer at the Tcf21 locus. This mouse line will permit the inducible expression of Cre recombinase in Tcf21-expressing cells. Using ROSA26 reporter mice, we show that Cre recombinase is specifically and robustly activated in multiple Tcf21-expressing tissues during embryonic and postnatal development. The expression profile in the kidney is particularly dynamic with the ability to cause recombination in mesangial cells at one time of induction and podocytes at another time. These features make the Tcf21-driven inducible Cre line (Tcf21(iCre) ) a valuable genetic tool for spatiotemporal gene function analysis and lineage tracing of cells in the heart, kidney, cranial muscle, and gonads.

Some Aspects of Protozoan Infections in Immunocompromised Patients: A Review (2002)

Protozoa are among the most important pathogens that can cause infections in immunocompromised hosts. These microorganisms particularly infect individuals with impaired cellular immunity, such as those with hematological neoplasias, renal or heart transplant patients, patients using high doses of corticosteroids, and patients with acquired immunodeficiency syndrome. The protozoa that most frequently cause disease in immunocompromised patients are Toxoplasma gondii, Trypanosoma cruzi, different Leishmania species, and Cryptosporidium parvum; the first two species cause severe acute meningoencephalitis and acute myocarditis, Leishmania sp. causes mucocutaneous or visceral disease, and Cryptosporidium can lead to chronic diarrhea with hepatobiliary involvement. Various serological, parasitological, histological and molecular methods for the diagnosis of these infections are currently available and early institution of specific therapy for each of these organisms is a basic measure to reduce the morbidity and mortality associated with these infections.
