Filler selection for weldments in type 316L stainless steel, for hot organic acid service

The weld metal corrodes much faster than the parent metal if type 316L steel welded with a matching filler is exposed to hot organic acids. Nine commercial filler metals were evaluated by preparing welded coupons and exposing them to different plant environments (with different organic acid mixtures and temperatures) for several months. The filler metals were chosen to yield different solidification modes, and to vary chromium, molybdenum and nickel contents. Only filler metals that are much more highly alloyed than the parent metal gave lower corrosion rates than the parent metal. Partitioning during and after solidification, and the average alloy content, both affect weld bead corrosion.
Purification and Activity Gel Analysis of Polynucleotide Phosphorylase from the Cyanobacterium Nostoc sp. MAC

SUMMARY: Polynucleotide phosphorylase has been purified from the cyanobacterium Nostoc sp. MAC. The enzyme requires a divalent cation such as Mg2+, has a pH optimum of 10·5 and catalyses the polymerization of ADP into polynucleotide in a primer-independent reaction at a rate of 2 μmol min-1 (mg protein)-1. It has an apparent native M r of 215000–240000. Non-denaturing polyacrylamide activity gels reveal a heterogeneous pattern of active bands similar to those previously observed with the corresponding enzyme from Micrococcus luteus, while SDS-denaturing activity gels reveal a single band of activity of M r 91000 in both crude extracts and the most highly purified fraction. Activity has also been demonstrated in a cetyltrimethyl-ammonium bromide non-denaturing activity gel. By analogy with other known polynucleotide phosphorylases, the Nostoc enzyme is probably a trimer of the 91000-M r subunit.
Why Returning to VET? Results of a Qualitative Comparative Study about English and German Car Mechatronics.

Educational choices, especially the influence of class on these choices have been a subject of lively international debate. However, thus far, there has been little international and comparative research with respect to vocational and education training (VET) decision making from a subject-oriented perspective. This paper considers occupational-biographical orientations of English and German car mechatronics and focuses on the roles of learning and gaining vocational qualifications. Drawing on the concept of occupational-biographical orientations, the paper describes three types of orientations based on analyses of findings from 11 autobiographical-narrative interviews with English and German car mechatronics. The interviews clearly showed that occupational-biographical orientations explained different views on the necessity of returning to (continuous) vocational education and training. They also demonstrated that subjective perceptions of the national VET system fostered particular occupational-biographical challenges, which supported or hindered existing learning attitudes. Overall, the findings suggested that occupational-biographical orientations exerted the most important influence on learning biographies and decisions to return to (continuous) VET.
Testing Granger causality with application to Exchange rates for Swedish kronor with GB pound and US dollar

This thesis undertakes the Causality study with application to exchange rates for Swedish kronor (SEK) with GB pound (£) and US dollar ($) in the frame work of vector Autoregressive (VAR) model. We present the theory behind the Granger Causality, unit roots and vector auto-regression. The Augmented Dickey-Fuller test for unit roots is performed. Our data consist of three time series of daily foreign exchange rates, starting from 23rd November, 2007 to 21st May, 2008. Granger causality is a technique for determining whether one time series is useful in forecasting another. By applying this technique, we try to observe the casual relationship which exists between the three currencies of our study.
Morpho-Physiological Characterization of Glyphosate-Resistant and -Susceptible Horseweed (Conyza canadensis) Biotypes of US Midsouth

Horseweed is traditionally considered a non-cropland weed. However, populations resistant to glyphosate have eventually become established in no-till agronomic cropping systems. Growth chamber and greenhouse experiments were conducted to compare selected biological and physi- ological parameters of glyphosate-resistant (GR) and -susceptible (GS) horseweed biotypes from Mississippi with a broader goal of fitness characterization in these biotypes. Vegetative growth parameters (number of leaves, rosette diameter and area, shoot and root fresh weights) were recorded weekly from 5 to 11 wk after emergence and reproductive attributes (days to bolting (production of a flowering stalk) and flowering) and senescence were measured for both GR and GS biotypes under high (24˚C/20˚C) and low (18˚C/12˚C) temperature regimes, both with a 13-h light period. Physiological traits such as net photosynthesis, phenolic content, and cell membrane thermostability, all in the presence and absence of glyphosate, and leaf content of divalent cations such as Ca 2+ and Mg 2+ were assayed in the two biotypes under the high temperature regime. All horseweed vegetative growth parameters except root fresh weight were higher in the high tem- perature regime compared to that in low temperature regime in both biotypes. Number of leaves, rosette diameter and area, shoot and root fresh weight were 40 vs. 35, 9.3 vs. 8.7 cm, 51 vs. 43 cm 2 , 3.7 vs. 3.2 g, and 3.5 vs. 4.2 g under high and low temperature conditions, respectively, when av- * Corresponding author.
Collocational information in the FrameNet database

The FrameNet lexical database yields information about collocations and multiword expressions in various ways. In some cases phrasal units have been entered from the start as lexical entries (write down). In other cases headword+preposition pairs can be recognized as special collocations where the preposition in question is a necessary and lexically specified marker of an argument of the headword tfond of, hostile to). Nominal compounds are annotated with respect to noun or (pertinative) adjective modifiers, some of which are analyzable but also entrenched (wheel chair, fiscal year). Nouns that name aggregates, portions, types, etc., sometimes hold lexically specified relations to their dependents (flock of geese). And event nouns frequently select the support verbs which permit them to enter into predications (file an objection, enter a plea). A subproject aims at extracting, as structured clusters of lexical items, the minimal semantically central kernel dependency graphs from the set of annotations. Such research will yield not only commonplace groupings (eat: dog, bone) but will also yield hitherto unnoticed collocations within such graphs (answer: you, door) where certain dependency links within them are idiomatic or otherwise lexically special, here answer > door. Collocational information can also be retrieved by various types of queries within our MySQL search tool.
Study on the Factors Affecting the Financing of High-Tech SMEs

High-tech small and medium-sized enterprises (SMEs) have played an important role in promoting the development of Chinese national economy, but most of them are still facing the difficulty in financing. This paper determines the major factors affecting the financing for high-tech SMEs by using multiple linear regression (MLR) method and significance test then comes to a conclusion that enterprise scale, enterprise growth, tangible asset ratio and equity liquidity have positive relationship with the financing of high-tech SMEs while profitability, accumulation, non-debt tax shield and solvency have negative effects.
NiO nanoparticles synthesis by chemical precipitation and effect of applied surfactant on distribution of particle size

Production of NiO by chemical precipitation is the approach utilized in this work. Materials mainly used in this project are nickel nitrate hex hydrate (as a basic material), sodium hydroxide (as a precipitator material), and the following surfactants (for reduction in particle size). Applied surfactants are in two kinds: polymeric (PVP, PEG) and cationic (CTAB) surfactants, 1.0 gram. Nanopowders properties are identified by TG, FTIR, XRD, SEM, and TEM. The results obtained confirm the presence of nickel oxide nanopowders produced during chemical precipitation.
‘When I’m Sixty-Four’: Old Age, Family Values, and Private Financial Transfers

Private financial transfers are becoming more and more important as ageing levels increase in Europe, with elders acting as both givers and receivers. Our study is divided in two main parts. In the first part we analyse the determinants of private financial transfers, using the Survey of Health, Ageing, and Retirement in Europe (SHARE). In the second part we analyse the importance of family values for these transfers, combining SHARE with European Values Study. We show that family functions as the main agent of private transfers. We conclude that family values drive financial transfers, mainly gifts provided by elderly individuals. We find that receipts by old-aged people are more related with need cases, such as illness and poorness; moreover, for these particular cases, family network plays a very important role, working as a safety net.

Economic Prospects and Conditions of Crowdfunding

This paper aims to present the conception of crowdfunding – the relatively new idea of raising funds from individuals which is made online by means of a web platform. Intent of this method is the ability to collect, manage and distribute finance using information and communications technology in order to develop particular project in exchange for provision of benefits. Article analyses and expands knowledge about essence of crowdfunding concept, its main types and characteristics. The subject of discussion of this paper are economic conditions for the application of social financing as a source of capital. The authors objective is to juxtapose the incentives and disincentives for both creators and funders. Crowdfunding as all other methods of raising capital is an action that carries risk. Novelty of the approach is researched through the prism of values that characterises all sources of capital. This article lead to the conclusion that main value of the method is to increase the probability of obtaining more beneficial solutions from the community than from the enterprises offering outsourcing services. Well-organized process of crowdfunding can finance start-ups and increase investment opportunities especially for small and medium enterprises.
Treatment of Fungal Infections with Semisynthetic Derivatives of Amphotericin B a

AME appeared to be as effective as AmB in the treatment of mycoses in humans. AME was much less nephrotoxic than AmB, and was better tolerated in terms of rapid onset and reversible adverse reactions. AME may be more ototoxic than AmB. AME, even as AmB and OAME, may cause neurotoxicity and leukoencephalopathy, particularly when high doses are given for long periods.

Epidemiology and Clinical and Radiographic Characteristics of Pneumonia in Kidney Transplant Recipients; 24-Year Experience

OBJECTIVE: Pneumonia increases morbidity and mortality in kidney transplant (KT) recipients. This study aimed to investigate characteristics of pneumonias in KT recipients by focusing on clinical and radiographic findings and diagnostic methods over a long study period. MATERIAL and METHODS: The medical records of kidney transplant recipients who had a diagnosis of pneumonia from 1988 to 2011 were reviewed retrospectively. RESULTS: Among 406 consecutive KT recipients, 20% had pneumonia during the study period and total 111 episodes of pneumonia developed in these patients. Fifty-six percent of the pneumonias were community acquired and 44% nosocomial. Bacterial infections were the most common cause (20%) and 13 (12%) of the episodes were polymicrobial. Antibiotic usage in the last three months was significantly more common in fungal pneumonia episodes than others. Bronchoscopy had the highest final overall diagnostic yield. CONCLUSION: Community-acquired pneumonia was more common, but it showed a more benign clinical course. Bacterial pneumonia was the most common cause, but polymicrobial infection was present in a significant number of KT recipients. Fungi can invade KT recipients, in particular, patients in the interval of 1-6 month after transplantation and patients who have used antibiotics in the last three months. KEy wORDS: Pneumonia, Kidney transplantation, Radiography, Physical examination, Nosocomial
Pre-Service Mathematics Teachers' Experiences with Proficiency-Based Learning.

Proficiency-based learning systems are becoming more common across the United States, yet few pre-service mathematics teachers have experienced this type of system in the classroom themselves. Teacher education courses are one opportunity for pre-service teachers to experience proficiency-based learning; however, we know little about the impact this type of experience might have. This study examines the experiences of six pre-service teachers in a secondary mathematics methods course implementing proficiency-based learning. Results show that the pre-service teachers experiences centred on four key affordances of the system (flexibility, multiple opportunities to demonstrate learning, awareness of progress and process, and awareness of gains in pedagogical content knowledge) and that they also identified challenges to its implementation.
Lack of association of transthyretin variations with spinocerebellar ataxia in north Indian population

Background & Objective: Transthyretin (TTR) has been associated with spinocerebellar ataxia (SCA) by several independent case reports. Coexistence of TTR and SCA mutations, overlapping clinical symptoms as well as altered levels of TTR in SCA patients suggest a correlation between TTR and SCA. To our knowledge, no large cohort based study has been attempted to examine the association of SCA with polymorphism in TTR gene. Here, we chose to investigate TTR variations in SCA patients (n=266) and controls (n=192) of North Indian ethnicity. Methods: We sequenced the exons including exon-intron boundaries of TTR gene in 55 patients and 55 controls. We observed four variations which were further genotyped by single base extension method (SNaPshot) in a larger cohort (SCA patients n=211 and controls n=137). Results: A novel synonymous variation c.372 C>G in exon 4 was detected in heterozygous condition in one control sample. We found nominal association for rs1800458 (Gly6Ser), with SCA (p-value < 0.05) which did not remain after Bonferroni correction for multiple tests. Pairwise linkage disequilibrium (LD) analysis revealed no LD between studied SNPs. Further, we employed two-marker sliding window analysis and observed a weak association of haplotype AT of rs1800458 and rs1667251 with SCA patients (p-value <0.05) which was not retained after Bonferroni correction. Conclusion: Our data suggests no association of genetic variations of TTR in SCA pathology.
Enhancement of Reversibility of Cr(III)/Cr(II) Redox Couple In Fe-Cr Flow Cell with Bi-Pb Electroplated Carbon Felts

Improvisation of Fe-Cr redox flow cell performance was significantly related to reversibility of the Cr(III)/ Cr(II) redox couple. To catalyze this redox reaction Bi and Pb metals were electroplated on carbon felt for reduction and oxidation of chromium. To achieve a better performance of redox flow cell these electroplated carbon felts are used on negative side of the flow cell. The flow cell experiments are carried out with only Bi electroplated felts using 0.01N PbCl2 as additive in anolyte and another carbon felts are electroplated with the combination of Bi-Pb and used on negative side of the cell without any additive. The experimental results observed that the Bi electroplated felts with PbCl2 additive shows 100% chromium reduction efficiency, 96% coulombic efficiency and 65% energy efficiency. While Bi and Pb combination felts without any additive has shown 100% chromium reduction efficiency, 98% coulombic efficiency and 72% energy efficiency. The cell operated with 5 liters of electrolytes containing 1.3N active materials dissolved in 2N HCl solution. 100 cm 2 carbon felt samples were utilized as electrodes at a current density of 50 mA/ cm 2 .

Controlled synthesis of CdE (E = S, Se and Te) nanowires

This work focused on a catalyst-free solution-based method to synthesize single-crystal CdE (E = S, Se and Te) nanowires. Using the hot coordinating solvents method, we have successfully synthesized high aspect ratio CdE nanowires. In this paper, we present our very recent results on the synthesis of CdTe nanowires and summarize our understanding of the effect of reaction parameters on the growth of CdE nanowires. The reaction parameters include ligands for Cd-complexes and E-complexes, ligand-to-Cd mole ratio, Cd-to-E mole ratio, precursor concentration, reaction temperature and the injection process. We propose the optimum conditions for the growth of CdE nanocrystals with a large aspect ratio. Possible growth mechanisms were also investigated using time-dependent studies. Furthermore, a Raman study shows a higher concentration of tellurium on the surface of CdTe nanowires. This is understandable because the free energy of Te is smaller than that of CdTe and thus Te crystals can easily form during the synthesis. Our high aspect-ratio nanowires have good dispersibility and exhibit huge potential applications in areas such as solution processed photovoltaic cells and transistors.
DNA Damage and Genomic Instability Induced by Inappropriate DNA Re-replication

Abstract : Chromosomal rearrangements and changes in copy number at various genomic loci are hallmarks of cancer cells and may be very early steps in tumorigenesis. The origins of genomic insults are poorly understood and this proposal aims to characterize one potential source of genomic instability inappropriate DNA re-replication. In a normal eukaryotic cell cycle the chromosomal DNA of a cell is replicated once and only once during S phase to ensure that each daughter cell receives exactly one complement of genomic material. By perturbing the regulation of several proteins involved in replication initiation our laboratory has been able to conditionally induce varying amounts of re- replication in yeast cells. We have demonstrated that re-replication induces a rapid and significant decrease in cell viability and a cellular DNA damage response. We elected to focus our studies of genome instability on gene amplification because of its clinical importance in breast cancer. We have shown that re-replication is a potent inducer of gene amplification that generates structures similar to amplicons seen but poorly understood in tumors. The high frequency at which these amplification structures are generated is specific to re-replication as similar structures are not observed when S phase DNA replication is impaired or DNA is directly damaged. We thus propose that re- replication arising from loss of replication control is a potential source of the genomic instability important for tumorigenesis.
Atmosphere–Ocean Coupled Variability in the South Atlantic

Abstract The climate variability of the South Atlantic region is determined from 40 yr (1953–92) of Comprehensive Ocean–Atmosphere Data Set monthly sea surface temperature (SST) and sea level pressure (SLP) data using the empirical orthogonal function (EOF) and the singular value decomposition (SVD) analysis methods. The EOF method is applied to each field separately, whereas the SVD method is applied to both fields simultaneously. The significance of the atmosphere–ocean interaction is revealed by a strong resemblance between individual (EOF) and coupled (SVD) modes of SST and SLP. The three leading modes of coupled variability on interannual and interdecadal timescales are discussed in some detail. The first coupled mode, which accounts for 63% of the total square covariance, represents a 14–16-yr period oscillation in the strength of the subtropical anticyclone, accompanied by fluctuations of a north–south dipole structure in the SST. The atmosphere–ocean coupling is strongest during the southern summe.
