The direction and magnitude of a solar sail acceleration are strongly related. For this reason, once the characteristic has been fixed, it is not possible to modulate in particular direction. In work, semi-analytical switching control law derived, enabling emulate smaller effective (without changes geometry or optical properties); by periodically changing pitch (cone) angle sail, average over t...

This article proposes that social scientists should explicitly recognize the existence of consumers who engage in ‘craft consumption’ and, hence, of an additional image of the consumer to set alongside those of ‘the dupe’,‘the rational hero’ and the ‘postmodern identity-seeker’. The term ‘craft’ is used to refer to consumption activity in which the ‘product’ concerned is essentially both ‘made ...

This performance study focuses on sommeliers, delving into what constitutes their work and the process of achieving this title. Sommeliers are wine specialists tasked with responsibility ensuring that beverages served properly in combination food. Similar to other craft persons, sommelier’s is connected knowledge products, primarily beverages, products’ relation different foods. The art tasting...

Abstract A diffractive sail is a solar whose exposed surface covered by an advanced metamaterial film with engineered optical properties. This study examines the optimal performance of Sun-facing attitude in typical orbit-to-orbit heliocentric transfer. attitude, which can be passively maintained through suitable design shape, obtained when nominal plane perpendicular to Sun–spacecraft line. Un...

As synthesized surface active ionic liquids (SAILs), Tetrapropylammonium Dodecylsulfate (TPADS), and Tetrabutylammonium (TBADS) have been characterized by FTIR, 1H-NMR 13C-NMR spectroscopic techniques. Conductometric UV-Visible probe investigations attempted to study the aggregation behavior of these SAILs in aqueous solution polymers Polyvinylpyrrolidone (PVP) Polyethylene glycol (PEG) at diff...

BY an arrangement with the Bermuda Natural History Society, apportunity is offered for a limited number of instructors and research students in zoology and botany to spend a few weeks at the Bermuda Biological Station this summer. Members of the expedition will sail from New York on the steamer Bermudian (Quebec Steamship Co.) at 11 A.M. on Wednesday, June 19, arriving in Bermuda June 21, and r...

There is a wide range of information available on by-product disposal methods used by large national breweries. However, little information is available on the methods of by-product disposal used by craft breweries. An investigation was carried out in which 200+ British craft brewers were contacted, of which 90 craft brewers provided basic information about their brewery operations and by-produ...

This article applies Campbell's (2005) theory of craft consumption to contemporary food culture. It argues that, besides cooking and the preparation of food, certain modes of domestic food growing can also be regarded as the craft consumption of food. At its core it tries to identify the conditions and possible motives for both modes of the craft consumption of food that can shed light on socia...
