Figure 1 Typical interconnect scheme of an α-Si:H module in superstrate configuration. P1, P2 and P3 AZD6094 cost indicate the different patterning steps. P1 is performed using an infrared laser to remove the front TCO. P2 and P3 use a green laser to cut the Si solar absorber layer and the rear electrode, respectively. In this letter, we demonstrate how the

energy density threshold for the scribing of the transparent contacts can be significantly reduced by replacing the standard thick AZO single layer with a 10 times thinner AZO/Ag/AZO multilayer structure with better electrical and optical properties. More specifically, for the lowest used pulse buy CFTRinh-172 energy, we measure a separation resistance for the AZO/Ag/AZO structure 8 orders of magnitude higher compared to much thicker AZO, currently used in thin film solar cells.

The experimental results and the numerical simulations provide clear evidences of the key role played by the silver interlayer to steep temperature increase at the DMD/glass interface, leading to a more efficient P1 scribing through a reduction of the fluence in a single laser pulse. These results could open great opportunities for the implementation of thin AZO/Ag/AZO electrodes 3 MA on large-area modules liable to segmentation, such as for α-Si:H solar panels. Methods AZO/Ag/AZO multilayers were sequentially deposited on conventional soda lime glass substrates by RF magnetron sputtering at room temperature in argon atmosphere with a working pressure of 1 Pa. A ceramic AZO target containing 2 wt.% Al2O3 and a pure Ag target were employed as source materials. The sputtering powers were 225 and 30 W for AZO and Ag, respectively. The deposition times were set in order to obtain 40 nm for both top and bottom AZO films and an optimum thickness of 10 nm for the Ag interlayer. This

value was selected to fabricate a DMD structure that has high optical transparency in the visible range and good electrical conductivity [5]. The thicknesses of the films were verified by Rutherford backscattering spectrometry (RBS; 2.0-MeV He+ beam) measurements in normal detection mode. Laser treatments were performed in air by a single Hydroxychloroquine mw pulsed (12 ns) Nd:YAG laser operating with an infrared (λ = 1,064 nm), Gaussian-shaped (FWHM = 1 mm) beam. The laser power was varied to obtain fluences in the range from 1.15 to 4.6 J/cm2. The morphologies of the AZO/Ag/AZO multilayer after the laser irradiation process were investigated by field emission scanning electron microscopy (SEM) using a Zeiss Supra 25 microscope (Oberkochen, Germany). Electrical sheet resistance (R sh) of about 8 Ω/sq was measured on the as-deposited DMD electrode using a four-point terminal method by employing an HL5560 system (Bio-Rad, Hercules, CA, USA), while the change of the conductivity due to laser ablation process has been mapped by lateral current–voltage characteristics acquired with a Keithley 4200 semiconductor characterization system (Cleveland, OH, USA).

Discussion In this paper we use morphology and sequence data from fresh collections and sequence data (types) downloaded from GenBank to detail the Botryosphaeriales, treating 15 type genera and describing two new genera and six new species from Thailand. Phylogenetic resolution of Botryosphaeriales The 28S rRNA gene (LSU) has been shown to be suitable for distinguishing many ascomycetes at the generic level due to its relatively conserved nature (Crous et al. 2006; Schoch et

al. selleck inhibitor 2006; Hibbett et al. 2007). By choosing comparisons of sequences of LSU, Crous et al. (2006) recognized ten lineages within the Botryosphaeriaceae and accepted Fer-1 manufacturer several genera, including those genera with sexual and/or asexual morphs. Separate names were not introduced for morphs of the newly proposed genera when sexual and asexual morphs were known. With the addition of EF1-α and

β-tubulin genes, and molecular data being available for more botryosphaeriaceous taxa, it is now possible to use combined multi-gene data to resolve complex selleckchem groups such as Diplodia/Lasiodiplodia, Phaeobotryon/Barriopsis and Dothiorella/Spencermartinsia which have yet to be resolved. In addition, new asexual genera and cryptic species have been introduced (Alves et al. 2008; Sakalidis et al. 2011). By combining EF1-α and β-tubulin genes with ITS, Phillips et al. (2005, 2008) reinstated the genus Neodeightonia in the Diplodia/Lasiodiplodia complex and also showed that the latter asexual genera are morphologically and phylogenetically distinct. ITS gene sequence data have been used

to distinguish the species within the genera of Botryosphaeriales (Denman et al. 2000, 2003; Denman et al. 2003; Alves et al. 2004; Barber et al. 2005). However, it has not been possible to apply ITS alone in resolving species in this study, because Botryosphaeriaceae Pyruvate dehydrogenase embodies species complexes. It is evident that at the generic level, the combined EF1-α and β-tubulin gene analysis is best for delimiting genera of Botryosphaeriaceae, as well as the species in several genera of Botryosphaeriales. It has also been recommended that the RPB2 gene should be considered in similar multi-combined genes analyses of genus and species levels of Botryosphaeriales (Pavlic et al. 2009a, b) and that some new approaches might be used for complex groups, such as Genealogical Sorting Index (GSI), which has been used to resolve the asexual morph of Neofusicoccum (Sakalidis et al. 2011). Maximum Parsimonious (MP), Randomized Axelerated Maximum Likelihood (RAxML) and Mr. Bayes are models for generating phylogenetic trees and were used in this study. Most phylograms were similar when using different models, however the bootstrap values differed. RAxML and Mr. Bayes have been shown to be suitable models for phylogeny at higher taxonomic levels (class, order and family) and large data analysis (Hibbett et al. 2007; Schoch et al. 2009a, b; Suetrong et al. 2009; Liu et al.

relies upon the introduction of PCR generated DNA into cells and not plasmids that have been isolated from ZD1839 an E. coli K-12 strain, we re-examined the DNA uptake efficiencies of the strains when transformed with a PCR generated version of the plasmid, pUC18. We reasoned that plasmids isolated from a K-12 strain may be subject to host restriction-modification systems in pathogenic strains, hence, using a PCR-generated pUC18 derivative would not only more closely resemble the conditions used by Datsenko and Wanner, but also allow us to monitor the transformation efficiencies by means of the acquired ampicillin resistance due to pUC18 plasmid uptake. Thus, we amplified pUC18 by PCR and then incubated the reaction with DpnI, which specifically digested the IACS-10759 cost methylated template plasmid and not the PCR generated see more product. The PCR generated pUC18 plasmid (pUC18PCR) was then transformed into MG1655, CFT073, O157:H7 Sakai and O42 by electroporation. The results (table 1) show that the transformation frequency of the pathogenic strains by pUC18PCR was slightly improved when compared with MG1655, although the overall transformation frequency remains far lower than MG1655. The overall number of MG1655

colonies identified after transformation with pUC18 or pUC18PCR was comparable. Thus, the electroporation step is likely to be the primary reason for the poor efficiency of this system in pathogenic E. coli strains. This shortcoming was alleviated somewhat by Murphy and Campellone

TCL [15] who developed an improved electroporation based protocol for recombineering in E. coli EHEC and EPEC strains. However, we have had mixed success using this protocol, particularly when recombineering in EAEC and UPEC strains, where no increase in recombination frequency was observed. B. Two-plasmid recombineering The two plasmid gene-gorging method described by Herring and co-workers [4] has an immediate advantage for recombineering in pathogenic strains since the method does not rely upon efficient electroporation as a means of introducing target DNA into the cell. Instead, the target DNA is flanked by recognition sites for the meganuclease I-SceI on a donor plasmid that is transformed into cells along with the recombineering plasmid, pACBSR, which carries I-SceI and the λ-Red genes whose expression is controlled by an arabinose inducible promoter. Induction of I-SceI results in donor plasmid cleavage, generating the linear dsDNA target, which is a substrate for λ-Red gene products. Herring and co-workers disrupted chromosomal genes by introducing amber mutations, using long regions of homology to the chromosome and reported that the recombination frequency for gene gorging was between 1-15%.

RC586 have <97.7% sequence identity with the rpoB sequences of all V. cholerae and V. mimicus strains included in this study. In a comparative DNA-DNA hybridization and ANI analysis, Adékambi et al. [23] demonstrated that rpoB <97.7% correlated with DNA-DNA hybridization <70% and ANI <95%, both being interpreted as demarcation thresholds for bacteria. All V. cholerae strains included in this study showed >99.5% rpoB sequence similarity with V. cholerae N16961 (data not shown). Based on a standard MLSA for the Vibrionaceae [21], Vibrio sp. RC341 and Vibrio sp. RC586 both have <95% pair-wise

similarity with V. cholerae, V. mimicus, V. vulnificus, and V. parahaemolyticus strains. All V. cholerae strains and both V. mimicus strains Lenvatinib used in this analysis demonstrated >95% similarity between concatenated genes of like-species (data not shown). Karlin’s dissimilarity signatures were also calculated between these two genomes and the Vibrio genomes used in this study. Vibrio sp. RC586 shared >10 dissimilarity with all V. cholerae (11.5 to 16.2), V. vulnificus (19.6), and V. parahaemolyticus (41.6) genomes, and > 7 with both V. mimicus strains. Vibrio sp. RC341 shared >10 dissimilarity for all V. cholerae (10.2 to 14) except V. cholerae B33 (9.4) and TMA21 (9.8). Vibrio sp. RC341 shared >10 genome signature dissimilarity with V. parahaemolyticus find more (40.2), V. vulnificus (16.3), and both V. mimicus (>14) genomes. Vibrio

sp RC341 and RC586 learn more shared a genomic dissimilarity of 8.7 with each other. Taken together these data indicate that Vibrio sp. RC341 and Vibrio sp. RC586 are new species with a high genomic relatedness to V. cholerae and V. mimicus. Evolution of Vibrio sp. RC341 and Vibrio sp. RC586 Lineages The phylogenies of Vibrio sp. RC341 and Vibrio sp. RC586 were inferred by constructing a supertree, using a 362,424 bp homologous alignment of V. cholerae, V. mimicus, and the new species (Figure 2). Based on the supertree analysis Vibrio sp. RC341 and Vibrio sp. RC586 are deeply rooted in SIS3 mw ancestral nodes, suggesting ancient evolution of the

two species. Results of this phylogenetic analysis suggest the Vibrio sp. RC341 lineage evolved from a progenitor of the V. cholerae and V. mimicus lineages (Figure 2), a finding supported by strong bootstrap support and further evidenced by the evolutionary distance of V. cholerae and V. mimicus from Vibrio sp. RC341 (see Additional file 7). The two V. mimicus strains are interspersed among V. cholerae, with respect to evolutionary distance, suggesting that evolutionary distances of V. cholerae and V. mimicus are equidistant from Vibrio sp. RC341 (see Additional file 7). Figure 2 Neighbor-joining tree based on 362,424 bp alignment of homologous sequences using the Kimura-2 parameter for nucleotide substitution.

The blood infection rate of S lugdunensis is around 0 3% [9], wh

The blood infection rate of S. lugdunensis is around 0.3% [9], which is lower than most other bacteria. However, there are an increasing number of Selleckchem Quisinostat reports on blood infections caused by this bacterium [10, 11]. The prevalence of S. lugdunensis varies greatly among different geographical

regions, including 1.3% in Japan [12], 0.8% in Korea [13], 3% in the U.S. [14], and 6% in Argentina [15]. While it is suspected that the incidence of this bacterium in Asiatic countries is similar, its incidence has not yet been investigated in China. One reason for the low detection and underappreciated infection rates of S. lugdunensis are that most clinical microbiology laboratories do not usually speciate CoNS [7, 16]. Therefore, accurate methods are needed in order to accurately determine incidence by speciation of CoNS isolates. While Frank et al. suggested that ornithine decarboxylase (ODC) and pyrrolidonyl arylamidase (PYR) tests could identify S. lugdunensis from CoNS [17], Tan et al. showed that these two tests could only be used as a preliminarily screen for the bacterium Sotrastaurin price [18]. Currently, it is believed that the sequence of the glyceraldehyde-3-phosphate dehydrogenase-encoding (gap) gene can be used to accurately identify S. lugdunensis[19]. Additionally, the current problem of drug resistance in CoNS

isolates is severe [20]. The rate of drug resistance of S. lugdunensis varies throughout the world and while it is susceptible to most antibiotics, there are case reports on its resistance to Fenbendazole some drugs [17, 18, 21, 22]. The objectives of the present study were to determine the frequency of S. lugdunensis in 670 non-replicate CoNS clinical isolates from the General Hospital of the People’s Liberation Army in China and to clinically and microbiologically characterize

them. Specifically, we determined drug resistance patterns and selleck kinase inhibitor molecular epidemiological characteristics, contributing to the clinical diagnosis and treatment of S. lugdunensis infections. Results Detection of S. lugdunensis isolates Eight out of the 670 isolates were positive for both ODC and PYR (single positives were not pursued further). Isolate 2 and 4 were positive in the Latex Agglutination test; however, only Isolate 4 was positive in the Slide Coagulase test. All isolates were negative in the subsequent Tube Coagulase test. Of these eight isolates, 4 were further validated by both VITEK 2 GP and API 20 Staph, with a sensitivity of 80% (4/5), one could not be accurately identified by either, and the other 3 were identified as S. haemolyticus (Table 1). The sequences of the gap gene for all 5 isolates were 99% identical to the corresponding S. lugdunensis sequence (GenBank accession number AF495494.1) (Figure 1). Hence, five out of the 670 CNS isolates were detected as being S. lugdunensis, a detection rate of 0.7% (5/670). Of the of five S.

C2. Strains from different hosts are represented by different geometric shapes as described in the upper left. Strains from herbivorous animals

are represented in pink and strains from omnivorous animals are in yellow. Edges between a strain and a genetic marker mean that the marker was detected for that strain. Each subgroup is highlighted by a dotted ellipse and labeled accordingly. A Chi-square value of 97.611, 15 degrees of freedom (D.F.), p < 0.0001, was obtained click here from a contingency table with the phylogenetic groups distribution among the hosts, allowing the null hypothesis, which states that there is no association between the hosts and the groups, to be rejected (p < 0.0001). This result suggests a significant difference in the E. coli population structure among the animals analyzed. A Chi-square test at the subgroup level was performed to verify

the existence of an association between the hosts and the phylogenetic subgroup. The calculated 155.251 Chi-square value (30 D.F.), leads to the rejection of the null hypothesis (p < 0.0001). A Chi-square test was also performed to verify the association between the hosts and the genetic markers (chuA, yjaA and TspE4.C2). The result (Chi-square value = 87.563, 10 D.F., p < 0.0001) indicated that the genetic markers are differently distributed among the hosts (Table 2).

As shown in Table 3, the largest diversity indexes were observed for humans (Shannon index = 0.6598, Simpson index = 0.7331) and pigs (Shannon index = 0.6523,

Simpson index = 0.7245), whilst the smallest diversity was observed for goats (Shannon index = 0.2614, Obeticholic Acid Simpson index = 0.3203). The Pianka’s Lonafarnib concentration similarity index was calculated using the phylogenetic subgroup distribution for each pair of hosts (Table 4). The results indicated that humans and pigs exhibited a similarity of 88.3%, whereas cows, goats and sheep exhibited an average similarity of 96%.

Reflection spectrum of ITO shows

the minimum reflection of SCH 900776 0.4% at 523 nm while reflection spectrum of TiO2 shows the minimum reflection of 3.5% at 601 nm within the 400- to 1,000-nm range. It means the Si absorbance increased by approximately 25% and 23% for ITO and TiO2 films, respectively. The low reflectance enhances the absorption of the incident photons and hence increases the photo-generated current in Si solar cells. It reveals that the RT RF sputtering deposition of ITO and TiO2 films can be used as anti-reflective coatings (ARCs) for Si solar cells. Figure 6 Reflectance spectra for ITO and TiO 2 layers with the as-grown Si sample. Conclusions The work presents the structural and optical characteristics of ITO and TiO2 ARCs deposited on a (100) P-type monocrystalline Si substrate by a RF magnetron sputtering

at RT. X-ray diffraction proved the anatase TiO2 and polycrystalline ITO films structure. Residual selleck inhibitor compressive strain was confirmed from the Raman analysis of the ITO and TiO2 films which exhibited blue shifts in peaks at 518.81 and 519.52 cm-1 excitation wavelengths, respectively. FESEM micrographs showed that the granules of various scales are uniformly distributed in both ITO and TiO2 films. Reflectance measurements of ITO and TiO2 films showed 25% and 23% improvement in the absorbance of incident light as compared to the as-grown R406 Si. Low reflectivity value of 10% in the ITO film as compared to 12% of the TiO2 film is attributed to the high rms value. Our results reveal that the highly absorbent polycrystalline ITO and photoactive anatase TiO2 can be obtained by RF magnetron sputtering at room temperature. Both ITO and TiO2 films can be used as ARCs in the fabrication of silicon solar cells. Acknowledgement The authors acknowledge the Short Term Research
