A novel method was developed for the determination of linting propensity of paper based on printing with an IGT printability tester and image analysis of the printed strips. On average, the total fraction of the surface removed as lint during printing is 0.01%-0.1%. This value is lower than those reported in most laboratory printing tests, and more representative of commercial offset printing applications. Newsprint paper produced on a roll/blade former machine was evaluated for linting propensity using the novel method and also printed on a commercial coldset offset press. Laboratory and commercial printing results matched well, showing that linting was higher for the bottom side of paper than for the top side, and that linting could be reduced on both sides by application of a dry-strength additive. In a second case study, varying wet-end conditions were used on a hybrid former machine to produce four paper reels, with the goal of matching the low linting propensity of the paper produced on a machine with gap former configuration. We found that the retention program, by improving fiber fines retention, substantially reduced the linting propensity of the paper produced on the hybrid former machine. The papers were also printed on a commercial coldset offset press. An excellent correlation was found between the total lint area removed from the bottom side of the paper samples during laboratory printing and lint collected on halftone areas of the first upper printing unit after 45000 copies. Finally, the method was applied to determine the linting propensity of highly filled supercalendered paper produced on a hybrid former machine. In this case, the linting propensity of the bottom side of paper correlated with its ash content.

We are constantly exposed to a variety of environmental contaminants and hormones including those mimicking endogenous estrogens. These highly heterogeneous molecules are collectively referred to as xenoestrogens and hold the potential to affect and alter the delicate hormonal balance of the human body. To monitor exposure and investigate potential health implications, comprehensive analytical methods covering all major xenoestrogen classes are urgently needed but still not available. Herein, we describe an LC-MS/MS method for the simultaneous determination of multiple classes of endogenous as well as exogenous estrogens in human urine, serum and breast milk to enable proper exposure and risk assessment. In total, 75 analytes were included, whereof a majority was successfully in-house validated in the three matrices. Extraction recoveries of validated analytes ranged from 71% to 110% and limits of quantification from 0.015 to 5 µg/L, 0.03 to 14 µg/L, and 0.03 to 4.6 µg/L in urine, serum and breast milk, respec-tively. The applicability of the novel method was demonstrated in proof of principle experiments by analyzing urine from Austrian, and breast milk from Austrian and Nigerian individuals. Thereby, we proved the methods’ feasibility to identify and quantify different classes of xenoestrogens simultaneously. The results illustrate the general importance of multi-class exposure assessment in the context of the exposome paradigm. Specifically, they highlight the need for estimating total estrogenic burden rather than single analyte or chemical class measurements and its potential impact in endocrine disruption and hormone related diseases including cancers.<br>

Insight Into

Abstract Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde has been seen as the nineteenth century prototype of the workings of the criminal mind. Similarly, current psychoanalytic readings of the novel suggest that it serves as a precursor to Freud’s theories on the structural model of personality, and repression and that Dr. Jekyll and Mr. Hyde can provide insight into the psychology of addiction, multiple personality disorder and borderline personality disorders, as these terms have currency in the discipline of modern psychology. Indeed, Stevenson’s novel can even be seen as a precursor to the very genre of Freud’s “case” study. In fact, current readings of Dr. Jekyll and Mr. Hyde continue to focus on its case study aspects, claiming that the novel shows “the composition and operation of the criminal mind” (Thomas qtd in Rosner, Spring 29). “Much Ado About Handwriting: Countersigning with the Other Hand in The Strange Case of Dr. Jekyll and Mr. Hyde is concerned with making a Gothic case “the composition and operation of the criminal mind,” but not because the word “composition” denotes a mental constitution that merely pre-exists the text or that the text refers to or represents a substantive criminal mind; instead the word suggests that there exists a displaced link between writing, reading, interpretation, and criminality as the shadowy “place” where the “other” begins and collusion enters the scene. Taking as a premise Jacques Derrida’s contention that “it is the ear of the other that signs,” this paper is concerned with “composition,” signatures and encryption as a way of exploring how these texts pose insoluble psychic double binds regarding the determination of criminality.

Linear Slide

This paper proposes a novel method to on-machine determine the three error components of a precision linear slide: the straightness motion, the yaw and the roll under the effect of thermal distortion caused by friction and drive. The Integrated Sensing System (ISS) is then introduced for implementing this novel method on an illustrative model of a linear slide. The error separation algorithm used in the system is based on the Fourier Eight Sensor (F8S) method. The theory and procedures are presented, and computer results are analyzed. The effectiveness of the novel method is validated through computer simulations.

Abstract Lipoperoxidation is implicated in various pathological conditions. Malonaldehyde (MDA) is the most commonly used marker of this process. We propose simple modifications to Yagi's fluorometric assay for MDA determinations, to avoid long and tedious manipulations by eliminating the first precipitation and washing steps, analogous to HPLC methods, and to increase both the sensitivity and the specificity of the assay by measuring synchronous fluorescence. The proposed technique is easier, faster, and more sensitive than Yagi's method (Academic Press, 1982: Lipid peroxides in biology and medicine). The results obtained with the novel method correlate with those from the HPLC method described by Therasse and Lemonnier (J Chromatogr Biomed Appl 1987;413:237-41).

Missing traffic data are inevitable due to detector failure or communication failure. Currently, most of imputation methods estimated the missing traffic values by using spatial-temporal information as much as possible. However, it ignores an important fact that spatial-temporal information of the traffic missing data is often incomplete and unavailable. Moreover, most of the existing methods are verified by traffic data from freeway, and their applicability to urban road data needs to be further verified. In this paper, a hybrid method for missing traffic data imputation is proposed using FCM optimized by a combination of PSO algorithm and SVR. In this method, FCM is the basic algorithm and the parameters of FCM are optimized. Firstly, the patterns of missing traffic data are analyzed and the representation of missing traffic data is given using matrix-based data structure. Then, traffic data from urban expressway and urban arterial road are used to analyze spatial-temporal correlation of the traffic data for the determination of the proposed method input. Finally, numerical experiment is designed from three perspectives to test the performance of the proposed method. The experimental results demonstrate that the novel method not only has high imputation precision, but also exhibits good robustness.

Gas liquid and thin layer chromatography have been combined into a single microphysicochemical technique. The resolution of two terpenoids found in nature—piperitone and piperitone oxide—is described to illustrate the scope of the novel method of analysis. Occurrence of the epoxide in Mentha arvensis (Japanese mint), Mentha piperita (Mitcham peppermint), Eucalyptus dives Schauer, "Type" ("broad-leaved peppermint"), and Eucalyptus numerosa Maiden, var. "A" is reported for the first time. Its presence in these species should prove of biochemical as well as taxonomic interest.

This paper presents the application of a new method for the identification and quantification of interval valued spatial uncertainty under scarce data.Specifically, full-field strain measurements, obtained via Digital Image Correlation, are applied in conjunction with a quasi-static finite element model.To apply these high-dimensional but scarce data, extensions to the novel method are introduced.A case study, investigating spatial uncertainty in Young's modulus of PA-12 parts, produced via Laser Sintering, shows that an accurate quantification of the constituting uncertainty is possible, albeit being somewhat conservative with respect to deterministic values reported in literature.
