Size and shape of plates and size of wine glasses and bottles: impact on self-serving of food and alcohol

Background The physical properties of tableware could influence selection and consumption of food and alcohol. There is considerable uncertainty, however, around the potential effects of different sizes and shapes of tableware on how much food and alcohol people self-serve. These studies aimed to estimate the impact of: 1. Plate size and shape on amount of food self-served; 2.Wine glass and bottle size on amount of wine self-poured. Methods 140 adults participated in two laboratory studies—each using randomised within-subjects factorial designs—where they self-served food (Study 1) and wine (Study 2): Study 1: 3 plate sizes (small; medium; large) × 2 plate shapes (circular; square). Study 2: 3 wine glass sizes (small; medium; large) × 2 wine bottle sizes (75 cl; 50 cl). Results Study 1: There was a main effect of plate size: less was self-served on small (76 g less, p < 0.001) and medium (41 g less, p < 0.001) plates, compared to large plates. There was no evidence for a main effect of plate shape (p = 0.46) or a size and shape interaction (p = 0.47). Study 2: There was a main effect of glass size: less was self-served in small (34 ml less, p < 0.001) and medium (17 ml less, p < 0.001) glasses, compared to large glasses. There was no evidence of a main effect of bottle size (p = 0.20) or a glass and bottle size interaction (p = 0.18). Conclusions Smaller tableware (i.e. plates and wine glasses) decreases the amount of food and wine self-served in an initial serving. Future studies are required to generate estimates on selection and consumption in real world settings when numerous servings are possible.

Optimization and Analysis of Multilayer Planar Spiral Coils for the Application of Magnetic Resonance Wireless Power Transfer to Wearable Devices

In this study, small multilayer planar spiral coils were analyzed and optimized to wirelessly charge an in-ear wearable bio-signal monitoring device in a wine-glass-shaped transmitter (Tx) based on magnetic resonance wireless power transfer (MR-WPT). For analysis of these coils, a volume filament model (VFM) was used, and an equivalent circuit formulation for the VFM was proposed. The proposed method was applied to design effective multilayer coils with a diameter and height of 6 and 3.8 mm, respectively, in the wearable device. For the coils, a printed circuit board having a 0.6 mm thick dielectric substrate and a 2 oz thick copper metal was used. Moreover, the coils on each layer were connected in series. The dimensions of the double-, four-, and eight-layer coils were optimized for the maximum quality factor (Q-factor) and coupling efficiency. The operating frequency was 6.78 MHz. The optimal dimensions for the maximum Q-factor varied depending on the number of coil layers, pattern width, and turn number. For verification, the designed coils were fabricated and measured. For the four-layer coil, the coupling efficiency and Q-factor using the measured resistance and mutual inductance were 58.1% and 32.19, respectively. Calculations showed that the maximum Q-factor for the four-layer coil was 40.8 and the maximum coupling efficiency was 60.1%. The calculations and measurement were in good agreement. Finally, the entire system of the in-ear wearable bio-signal monitoring device, comprising a wine-glass-shaped transmitter, the designed receiving coil, and a monitoring circuit, was fabricated. The measured dc-dc efficiency of the MR-WPT system was 16.08%.

A voluptuary under the horrors of digestion

The voluptuary is the Prince of Wales (and future George IV), who lounges in an armchair in Carlton House, using a fork as a toothpick. Gillray provides a number of props testifying to his love of excess: decanters of port and brandy, empty wine-bottles, and a dice-box. Gillray’s satirical coat of arms shows a plate with a crossed knife and fork, with a candle stuck in a wine-bottle, another in a wine-glass.

A Somewhat Dour Introduction

This introduction offers an overview of the basic themes of the book, highlighting the author’s sense of gloom and doom, his view of life as a series of failures in a game of humiliation as the score gets evermore lopsided as one ages. It also provides some autobiography. The chapter’s centerpiece is an account of an embarrassing incident at All Souls College where the author, as in Thor’s visit to Útgarðaloki, found his wine glass connected to the sea. He made a drunken fool of himself before portraits of some of his heroes that graced the walls of the room where the event occurred.

‘Thus am I accustomed to treat friends’

This contribution focuses on a superb Dutch wine glass or roemer engraved by Maria Roemers Visscher (‘Tesselschade’) with the Latin motto, Sic Soleo Amicos (‘Thus am I accustomed to treat friends’). Roemers’ roemer is shown actively to have participated in a coterie of cultured men and women initially centred on her father Roemer Pieterszoon Visscher, whose friendly gatherings in the 1610s were animated by wine, song, emblems, poetry and comic and satirical literature. The roemer’s inscription characterises it as a speaking subject within this milieu and evokes the intersubjective character of friendships that were enacted through puns, metaphors, ironic wit and at times amorous play. The performance of mixed friendship through the gendered artistic practice of glass-engraving is compared with the pleasurable game of connecting word and image in emblems. Such activities both gave rein to, and reined in, embodied friendships between elite women and men within a pleasure-loving yet patriarchal society.

Association of habitual alcohol consumption with carotid atherosclerotic lesions: results from the Corinthia study

Introduction Alcohol is implicated in the pathophysiology of cardiovascular diseases. However, it is also believed to play a cardioprotective role if consumed in appropriate amounts. Purpose To assess the association between alcohol consumption and carotid atherosclerosis. Methods In the setting of the cross-sectional Corinthia study, volunteers filled in questionnaires regarding drinking habits and were characterized as social drinkers (SD) or habitual alcohol consumers (HAC). Furthermore, they underwent carotid ultrasonography examination to evaluate the carotid intima-media thickness (cIMT). Thickness of cIMT&gt;1.5 mm or protrusion &gt;50% compared to adjacent segments was considered as atherosclerotic plaque. Results HAC consumers were usually male (HAC: 61.1%, SD: 24.9%, p&lt;0.001), smokers (HAC: 33.3%, SD: 23.5%, p&lt;0.001) and frequently had a history of hypertension (HAC: 72.8%, SD: 67.5%, p=0.02) when compared to SD (Table 1). However, no significant differences were noted regarding other risk factors of atherosclerosis (Table). Notably, HAC had a greater extent of carotid atherosclerosis as demonstrated by an increased cIMT (HAC: 1.03±0.45mm, SD: 0.96±0.39mm, p&lt;0.001) and carotid plaque burden (HAC: 27.7%, SD: 21.3%, p=0.004). Importantly, when taking into account the number of alcoholic drinks (in wine glasses), alcohol consumption of more than 1 wine glass resulted in significantly higher values of cIMT (1 wine glass: 1.00±0.42mm, &gt;1 wine glass: 1.06±0.45mm, p=0.04) (Figure 1A) and extensive amount of carotid plaques (1 wine glass: 22.7%, &gt;1 wine glass: 30.4%, p=0.02) when compared to consumption of 1 wine glass (Figure 1B). Conclusion Habitual alcohol consumption of more than one wine glass is associated with a higher carotid atherosclerotic burden. Figure 1 Funding Acknowledgement Type of funding source: None
