<p>This is an "authorship" study of New Zealand artist Joanna Margaret Paul, with specific reference to her "experimental film" works. Though I will draw on a wide range of theorists, my overall approach is what Laura Marks calls "intercultural cinema." For Marks the term "intercultural cinema" refers to a specific "genre" or "movement" of experimental films created by authors caught "between two or more cultural regimes of knowledge." Intercultural film-makers include feminist, queer, indigenous and immigrant authors (any "minority" which possesses its own "regime of knowledge" and makes experimental film) living in "Western metropolitan areas," whose dominant culture is capitalist, masculine, "hegemonic, white and Euro-American" (a second regime of knowledge). What draws intercultural cinema together (and indeed, one could argue, experimental film in general) is an oppositional stance toward capitalist ideology, the commodification of the art object and the uniformity of classical narrative forms. As David Bordwell and Kristen Thompson write, experimental films are "often deliberate attempts to undercut the conventions of commercial narrative filmmaking" and, as Marks writes, intercultural cinema "flows against waves of economic neocolonialism," and is "suspicious of mass circulation... [as] making commercial cinema still involves significant compromises."</p>

Background: Gestational TSH and FT4 reference intervals may differ according to assay method but the extent of variation is unclear and has not been systematically evaluated. We conducted a systematic review of published studies on TSH and FT4 reference intervals in pregnancy. Our aim was to quantify method-related differences in gestation reference intervals, across four commonly used assay methods, Abbott, Beckman, Roche, and Siemens. Methods: We searched the literature for relevant studies, published between January 2000 and December 2020, in healthy pregnant women without thyroid antibodies or disease. For each study, we extracted trimester-specific reference intervals (2.5–97.5 percentiles) for TSH and FT4 as well as the manufacturer provided reference interval for the corresponding non-pregnant population. Results: TSH reference intervals showed a wide range of study-to-study differences with upper limits ranging from 2.33 to 8.30 mU/L. FT4 lower limits ranged from 4.40–13.93 pmol/L, with consistently lower reference intervals observed with the Beckman method. Differences between non-pregnant and first trimester reference intervals were highly variable, and for most studies the TSH upper limit in the first trimester could not be predicted or extrapolated from non-pregnant values. Conclusions: Our study confirms significant intra and inter-method disparities in gestational thyroid hormone reference intervals. The relationship between pregnant and non-pregnant values is inconsistent and does not support the existing practice in some laboratories of extrapolating gestation references from non-pregnant values. Laboratories should invest in deriving method-specific gestation reference intervals for their population.

Ultrasound Investigation

Objectives: Duplex ultrasound investigation has become the reference standard in assessing the morphology and haemodynamics of the lower limb veins. The project described in this paper was an initiative of the Union Internationale de Phlébologie (UIP). The aim was to obtain a consensus of international experts on the methodology to be used for assessment of the anatomy of superficial and perforating veins in the lower limb by ultrasound imaging. Design: Consensus conference leading to a consensus document. Methods: The authors performed a systematic review of the published literature on duplex anatomy of the superficial and perforating veins of the lower limbs. Afterwards, they invited a group of experts from a wide range of countries to participate in this project. Electronic submissions from the authors and the experts (text and images) were made available to all participants via the UIP website. The authors prepared a draft document for discussion at the UIP Chapter meeting held in San Diego, USA, in August 2003. Following this meeting, a revised manuscript was circulated to all participants and further comments were received by the authors and included in subsequent versions of the manuscript. Eventually, all participants agreed on the final version of the paper. Results: The experts have made detailed recommendations concerning the methods to be used for duplex ultrasound examination as well as the interpretation of images and measurements obtained. This document provides a detailed methodology for complete ultrasound assessment of the anatomy of the superficial and perforating veins in the lower limbs. Conclusions: The authors and a large group of experts have agreed on a methodology for the investigation of the lower limbs venous system, by duplex ultrasonography, with specific reference to the anatomy of the main superficial veins and perforators of the lower limbs in healthy and varicose subjects.

Microscopy Images

Fluorescent probes can be used to detect various types of asbestos (serpentine and amphibole groups); however, the fiber counting using our previously developed software was not accurate for samples with low fiber concentration. Machine learning-based techniques (e.g., deep learning) for image analysis, particularly Convolutional Neural Networks (CNN), have been widely applied to many areas. The objectives of this study were to (1) create a database of a wide-range asbestos concentration (0–50 fibers/liter) fluorescence microscopy (FM) images in the laboratory; and (2) determine the applicability of the state-of-the-art object detection CNN model, YOLOv4, to accurately detect asbestos. We captured the fluorescence microscopy images containing asbestos and labeled the individual asbestos in the images. We trained the YOLOv4 model with the labeled images using one GTX 1660 Ti Graphics Processing Unit (GPU). Our results demonstrated the exceptional capacity of the YOLOv4 model to learn the fluorescent asbestos morphologies. The mean average precision at a threshold of 0.5 ([email protected]) was 96.1% ± 0.4%, using the National Institute for Occupational Safety and Health (NIOSH) fiber counting Method 7400 as a reference method. Compared to our previous counting software (Intec/HU), the YOLOv4 achieved higher accuracy (0.997 vs. 0.979), particularly much higher precision (0.898 vs. 0.418), recall (0.898 vs. 0.780) and F-1 score (0.898 vs. 0.544). In addition, the YOLOv4 performed much better for low fiber concentration samples (<15 fibers/liter) compared to Intec/HU. Therefore, the FM method coupled with YOLOv4 is remarkable in detecting asbestos fibers and differentiating them from other non-asbestos particles.

Survival Mode

Abstract Oscillating Wave Surge Converters (OWSCs) are designed to enter survival mode during extreme wave conditions where they forego the opportunity to extract energy to preserve structural integrity. While this is a good tradeoff, it is important that OWSC technology progresses to a point where energy is constantly extracted as long as waves are present. This work addresses the need for an OWSC that can extract wave energy in a wide range of sea conditions while minimizing structural overloading by regulating the fluid-structure interaction. The OWSC being studied here was conceptually designed and patented by researchers at NREL. It consists of a flap face that resembles household blinds, where the flaps can be opened or closed to accommodate the sea conditions. The performance of this variable geometry OWSC in various, shallow wave states was studied in two numerical modeling programs. Of particular interest were the flap’s hydrodynamic coefficients and potential power generation at a specific reference site. This configuration was predicted to mitigate wave forces by allowing some of the wave energy to pass through the device, thus preserving its structural integrity.

Direct Investigation

1 Coroners' files have been examined to ascertain the numbers of deaths involving self-poisoning with analgesic drugs with specific reference to the paracetamol/dextropropoxyphene combination. The period of study was 1976-1980. This report concentrates on cases in England, although reference is made to similar deaths occurring in Scotland and Northern Ireland. 2 Data have been collected extensively on a wide range of issues concerning fatal self-poisonings mainly by visiting coroners' offices in England to make direct investigation of records. 3 The total number of cases where the paracetamol/dextropropoxyphene combination can be considered as ingested in the self-poisoning episode is underestimated. The number of cases involving alcohol and/or other drugs taken together with the combination product is particularly underestimated. 4 Involvement of people aged 30 years and below comprises 32% of all cases. 5 'Gesture' overdoses comprise an estimated 14% of all cases in England. 6 An analysis of fatalities from cases where quantities in post-mortem blood of dextropropoxyphene < 1 μg/ml and paracetamol < 50 μg/ml are found and of cases where death occurs within 2 h of ingestion of the overdose has been carried out. The results are inconclusive. In most cases alcohol and/or other drugs are found to be involved. Critical inspection of coroners' files shows relatively few of these cases where the combination product is ingested on its own. 7 There is wide variability in the data available in coroners' files. In many cases data of value to this research are not recorded. Medical history and quantitative levels of drugs suspected (particularly dextropropoxyphene) are particular examples of factors which may not be recorded. 8 Office of Population, Censuses and Surveys (OPCS) mortality data are based on certified causes of death. Because of the underestimate of the involvement of this combination product and the under-reporting of other drug and/or alcohol ingestion with the combination, care must be exercised in quoting or drawing conclusions from OPCS statistics.

Natural Rubber Vulcanizates

Abstract Mathematical modeling of the dynamic behavior of vulcanizates is reviewed with the emphasis on carbon black filled natural rubber (NR). The 3 constant standard triboelastic solid (STS) model and its behavior are described, in general terms and with specific reference to low frequency shear data for a wide range of filled NR vulcanizates. Good general agreement is found between model and experiment for the data obtained at strain amplitudes down to 0.01; there is also acceptably good correlation between carbon black loading and values of STS constants. For previously published data down to very low strain amplitudes (1×10−4), agreement is much less satisfactory.

Vector graphics and 3D modeling have opened up a wide range of perspectives for designers to create various art objects. The use of computer graphics greatly simplified the process of sketch creating, as it provided the ability to change, add colors, and edit entire groups of objects. 3D modeling made it possible to recreate products, taking into account the smallest details in a virtual environment, compose an interior, and perform animation of various processes. The research object is the computer programs Corel Draw and 3D max and their importance for the methodology of development and creation of art objects. As a result of the study, it was found that vector graphics and 3D modeling programs not only made it easier for designers to create art objects, but also made it possible to improve the level of design by changing the usual perception. According to the authors, software products influenced the development of design, which made it possible to create any objects in a virtual environment.

Fat mass and fat-free mass have become useful clinical indices in determining healthy growth and physical development during critical periods of childhood and adolescence; however, despite a wide range of nutritional surveillance its study is limited by a lack of reference data. The purpose of this study was to establish sex-specific and age-specific standards for fat mass and fat-free mass in a large sample of Croatian children and adolescents. In this cross-sectional study, we collected data from 12,678 participants aged 11 to 18 years old (mean age ± standard deviation (SD): 14.17 ± 2.25 years; height 164.56 ± 11.31 cm; weight: 57.45 ± 13.73 kg; body mass index: 21.24 ± 3.67 kg/m2; 53% girls). Fat mass and fat-free mass were measured three times by bioelectrical impedance. The Lambda, Mu and Sigma methods were used to create percentile charts for fat mass index (FMI) and fat-free mass index (FFMI; fat mass and fat-free mass divided by height2). Sex and age differences were calculated using an analysis of variance (ANOVA) with post hoc comparisons. Boys had lower FMI (from 2.66 to 3.89) and higher FFMI values (from 16.90 to 17.80) in all age groups, compared to girls (for FMI from 2.79 to 5.17 and for FFMI from 14.50 to 14.90, p < 0.001). In boys, FMI slightly declined until the age of 14, after which an increase from the age of 15 to 18 was observed. In girls, FMI gradually increased from the age of 11 to 18 (p < 0.001). In general, FFMI increased by age in boys [F(7,5440) = 52.674, p < 0.001], while girls had more stable FFMI across all age groups [F(7,7222) = 2.728, p = 0.057]. The newly established sex-specific and age-specific reference data could be used for national surveillance and to screen for children and adolescents with high FMI and low FFMI.
