Coffee story: Unveiling indigenous delicacy through sensorial transaction

This paper explores the potential of spatial atmosphere as the basis of a coffee stall design, creating an intimate understanding of the possible sensory transactions that occurred throughout the coffee-brewing process. In this reflective piece, a coffee stall design process is presented and dissected to unveil the programmatic basis of the design. A closer look at multi-sensory experiences that include sight, smell, and sound in the process of brewing is considered essential. They hold a significant role in perceiving the surrounding atmosphere and how it impacts our design process. A series of equipment and ingredient tracing is conducted to identify the optimal barista's workflow and the production of a multi-sensory experience, rethinking the purpose of the surrounding objects from two different perspectives. Such a process positioned the atmosphere exploration as a focus in achieving a unique programme where the objects within the coffee-making process generate the space through materiality and immateriality.

Corona discharge of a vibrated insulating box with granular medium

Corona discharges are luminous signs of strong local electric fields allowing a continuous discharge into the surrounding atmosphere. They commonly occur at the ends of conductors at high voltage. Here we report the observation of a faint glow surrounding an insulating cm-sized box filled with mm-sized basalt beads. At an ambient pressure in the mbar range two light bands occur as soon as and only if the box is vibrated and only if it is filled with a granular medium. In addition, a glow also occurs at the inside of the box. We measured periodic electric fields at the outside of the box with spatial peaks at the positions of the light bands. The period correlates to the vibration frequency. These observations imply strong alternating fields beyond atmospheric breakdown, which are generated inside and also emerge at the outside of the insulating box. The observations can be explained by tribocharging and periodic displacement of charges between grains and the inside walls of the box.

Physical properties of bright Ca II K fibrils in the solar chromosphere

Context. Broad-band images of the solar chromosphere in the Ca II H&K line cores around active regions are covered with fine bright elongated structures called bright fibrils. The mechanisms that form these structures and cause them to appear bright are still unknown. Aims. We aim to investigate the physical properties, such as temperature, line-of-sight velocity, and microturbulence, in the atmosphere that produces bright fibrils and to compare those to the properties of their surrounding atmosphere. Methods. We used simultaneous observations of a plage region in Fe I 6301-2 Å, Ca II 8542 Å, Ca II K, and Hα acquired by the CRISP and CHROMIS instruments on the Swedish 1 m Solar Telescope. We manually selected a sample of 282 Ca II K bright fibrils. We compared the appearance of the fibrils in our sample to the Ca II 8542 Å and Hα data. We performed non-local thermodynamic equilibrium inversions using the inversion code STiC on the Fe I 6301-2 Å, Ca II 8542 Å, and Ca II K lines to infer the physical properties of the atmosphere. Results. The line profiles in bright fibrils have a higher intensity in their K2 peaks compared to profiles formed in the surrounding atmosphere. The inversion results show that the atmosphere in fibrils is on average −100 K hotter at an optical depth log(τ500 nm) = −4.3 compared to their surroundings. The line-of-sight velocity at chromospheric heights in the fibrils does not show any preference towards upflows or downflows. The microturbulence in the fibrils is on average 0.5 km s−1 higher compared to their surroundings. Our results suggest that the fibrils have a limited extent in height, and they should be viewed as hot threads pervading the chromosphere.

Defense Management and PESTLE Analysis

Militaries are in a changing and evolving environment. Defence management, with references to both military science and general management field, is seeking possibilities, opportunities and methods for being transformed in this dynamic environment and contexts. Managing, commanding and leading requires to know what is around, how is the surrounding atmosphere of organizations, what are the current socio-political, economic, environmental, scientific and legal situations to be considered? PESTLE analysis is giving a chance to defence managers for answering these questions. In this article we will discuss PESTLE model and try to find a solution how we can enhance it through a strategic approach.

Horror and Gothic in the 1970s

This chapter considers some of the possible influences on Misty, drawing links with other comics as well as a wider tradition of horror across multiple media in 1970s Britain. It explores the surrounding atmosphere of cultural horror, looking closely at the political context of 1970s Britain, which manifests in the presence of social commentary in Misty. It explores the large number of tales that revolve around animal rights, environmental issues, or social commentary (delinquency, poverty, and so forth). It then considers the surrounding atmosphere of British cultural and literary horror, with a particular focus on the horror and mystery stories being offered to children and shown on television and in schools. It argues that Misty’s stories are strongly influenced by the atmosphere of cultural horror emerging in Britain in the 1970s and particularly by ideas of transgression and punishment expressed in horror cinema and public information films.

Optical Detection of Vapor Mixtures Using Structurally Colored Butterfly and Moth Wings

Photonic nanoarchitectures in the wing scales of butterflies and moths are capable of fast and chemically selective vapor sensing due to changing color when volatile vapors are introduced to the surrounding atmosphere. This process is based on the capillary condensation of the vapors, which results in the conformal change of the chitin-air nanoarchitectures and leads to a vapor-specific optical response. Here, we investigated the optical responses of the wing scales of several butterfly and moth species when mixtures of different volatile vapors were applied to the surrounding atmosphere. We found that the optical responses for the different vapor mixtures fell between the optical responses of the two pure solvents in all the investigated specimens. The detailed evaluation, using principal component analysis, showed that the butterfly-wing-based sensor material is capable of differentiating between vapor mixtures as the structural color response was found to be characteristic for each of them.

Study the Concentration of SO2 Emitted From Daura Refinery by Using Screen View Model

In this study, the concentrations of sulfur dioxide (SO2) were emitted from the Daura oil refinery units and their effect on the surrounding areas of the refinery were investigated, and also, study the atmospheric stability effective by using the Screen View model, and check the effect of the wind speed and direction on the spread of pollutants. As indicated during this study, the physical factors of the sources of pollution, such as the height of the chimney, its diameter and the surrounding environmental conditions, contributed to the increase in the concentration of contaminants. It was generally observed that the concentration of SO2 increased by increasing the rates of airflow and ambient temperature. This work was prove the influences of weather conditions in the transmission and spread of pollutants such as wind speed, wind direction, atmospheric stability and ambient temperature, but the effect of ambient air temperature was lower than others variables. When the distance increases between the plume and the source of pollution, a heat exchange takes place with the surrounding atmosphere, the difference between the temperature of the emitted gas and the surrounding atmosphere decreases and the buoyant force increases. This leads to a lack of vertical movement that disperses the contaminants. In addition, the concentration of the pollutants decreases with the distance increases from the source of the pollution. In the present work, emission rate of SO2, and stack gas exit velocity calculated for all stacks (point sources) of the twelve production units during August 2013, and February 2014 by using the actual amounts of fuel consumed in Daura refinery in this period.
