Transfinite Version of Welter’s Game

We study the transfinite version of Welter’s Game, a combinatorial game played on a belt divided into squares numbered with general ordinal numbers. In particular, we give a solution for the game, based on those of the transfinite version of Nim and the original version of Welter’s Game using Cantor normal form

Costume and make up in cultural development

Costume is an essential feature of any dramatic production and with make- up constitutes the total visual appearance of the actor. Costume is an important fact of acting; therefore it is not mere covering for an actor. Thus its essence is rooted in the fact that the actor wears it, moves and speaks in it and is continually within the attention of the spectator. Costume assists characterization so that whether in film or on stage, the audience can determine age, social status, personality, nationality, dislikesand likes before the character utters a word. Costume also helps to establish the relationship between characters. The actor and the costume interpret the character. This in essence means that the proper coordination of the production elements contribute in boosting the cultural image of the people whose lives are reflected in the stories being dramatised on stage or in films. Costumes and make up could therefore become effective tools for cultural promotion and development if well manipulated. It then meansthat film transforms all subjects and objects into new signs which 189 190 communicate to the audience. In essence, film is rooted in the  communication and promotion of ideas, and ideas serve as a veritable instrument of enlightenment and education

Delete Nim

We study a game (called Delete Nim) that requires the OR operation to calculate the G-values of its positions. Also, the concept called 2-adic valuation, which is described in number theory, is used. This is very rare in the analysis of impartial games, while the XOR operation is commonly used for calculations of the G-values

Re-positioning Nigeria’s radio broadcast as a catalyst for development

Throughout history, communication and information culture have remained a powerful means of disseminating information. Communication has become an infrastructure for the flow of information across all sectors even though there is imbalance, misrepresentation, and bias of news flow from western media concerning the third world. This paper critically looks at news report on the south (third world) and takes a stand that the bias reports of events and negative portrayal of the south by the industrialised nations is intentional attempt to distract the south from having a focus. In conclusion, the paper, focuses on the Development Media Theory and Social Responsibility Theory arguing that this trend must be consciously viewed as a real challenge by the Nigeria radio broadcast that needs not waste time to counter the negative trend being perpetuated over the years but however to reposition her radio broadcasts to focus on the task of serving as a catalyst for the development of Africa and the country in general. At the end, the paper provides an outline of how radio could be used in developing Nigeria

Impact of wind-driven rain on historic brick wall buildings in a moderately cold and humid climate: Numerical analyses of mould growth risk, indoor climate and energy consumption

This paper gives an onset to whole building hygrothermal modelling in which the interaction between interior and exterior climates via building enclosures is simulated under a moderately cold and humid climate. The focus is particularly on the impact of wind-driven rain (WDR) on the hygrothermal response, mould growth at interior wall surfaces, indoor climate and energy consumption. First the WDR load on the facades of a 4×4×10 m3 tower is determined. Then the hygrothermal behaviour of the brick walls is analysed on a horizontal slice through the tower. The simulations demonstrate that the impact of WDR loads on the moisture contents in the walls is much larger near the edges of the walls than at the centre. The obtained relative humidity and temperature at the interior wall surfaces are combined with isopleths of generalised spore germination time of fungus mould. The results show that WDR loads can have a significant impact on mould growth especially at the edges of the walls. Finally, for the case analysed, the WDR load causes a significant increase of indoor relative humidity and energy consumption for heating.status: publishe

Investigation of the transport properties for saline water in porous materials -- Modeling of the permeability coefficient for saline water--

8th International Building Physics Conference (IBPC 2021) 25-27 August 2021, Copenhagen, DenmarkSalt weathering is a major concern for cultural heritages such as ruins and tombs, and desalination by poulticing is an interesting potential method to efficiently remove contaminating salt. Predicting the degree of achievable desalination is very important. However, many existing models used to consider saline water transport in porous materials have been developed based on the theory of pure water. To understand saline water flow in porous materials, we determined the saline water permeability of a tuff stone by the falling-head method. We found that the permeability of the tuff stone was affected by factors other than the density and dynamic viscosity of the saline water

X-ray CT and digital volume correlation of Tuff stone under uniaxial compression

International audienceWe present X-ray CT of a dry or wet tuff stone specimen under uniaxial compression. The obtained CT data were analyzed using a digital volume correlation software to determine the displacement and strain fields
