ABSTRACT

The incorporation of acoustic comfort and strategies into public library design is discussed in this paper. For decades, one of the main goals of acoustic theory and experiments has been to solve architectural acoustic issues. Recent contributions by the soundscape approach have highlighted wider beneficial goals that acoustic designers can follow, such as encouraging ecological reasoning about the acoustic system and its understanding as a whole. Using references from the literature, this paper illustrates the application of architectural acoustics and soundscape methods into the field of architectural architecture education, stressing the importance of unique design circumstances and aural teaching strategies in learning contexts. According to the findings of this study, the incorporation of Acoustic comfort can be accomplished by architectural design rather than active means, and the literature review discusses all methods of achieving Acoustic comfort or Architectural Acoustics. This research would look at potential noise sources as well as steps or technology that can be incorporated into the architectural design of a public library to improve acoustic comfort. HVAC, atmospheric noise from outside the lecture room, low sound insulation construction materials, and so on are examples of noise sources.

Keywords: Acoustic design, soundscape, architectural acoustics, education, acoustic comfort.

ABSTRACT

A library is a well-planned facility where information’s are curated collection from a source or similar resources, selected by experts and are made accessible to a defined community for reference or borrowing is of high importance. A library that is designed with keen consideration on proper spatial organization and relationship to optimize efficiency and ensure it is a digitally considered space. Library should no longer be confined places  but should adopt and open spatial plan that will allow interaction between scholars this why including  learning commons are necessary, in line with this, emphasis on design methods that will allow for purpose is highlighted here. The functionality of the library space and how this space relate is dependent on how functional and the spaces flow into themselves. Principles and guidelines in achieving this paper carefully examined.  This paper therefore seeks to emphasize principles that should be adhered, to ensure the optimization of space and how they relate to themselves through the review of studies and related articles.

Keywords: Library, Spatial Organization, Optimal Efficiency, Learning Common.

ABSTRACT

In order to respond to the harsh environmental challenges, buildings are evolving to adapt to meet the needs of the people without harming the environment within its context. This research considers the Muttrah fish market project located in Muscat city, Oman and how it successfully implemented sustainability principles into its design process and construction. Several traditional markets in Oman experienced a great competition from the entrants of modern markets. The traditional markets failed to compete because of poor planning, inconvenient access, overcrowded trading activities, lack of air circulation and poor sanitation, affecting thousands of vendors. The former local market of Muttrah needed a new design to upgrade its commercial operations, in response to this, a more sustainable development model for Oman’s traditional markets is proposed based on sustainability and hopefully could become an example of traditional market revitalization in Oman.

DETERMINATION OF SCHWARZSCHILD’S RADIUS OF SOME PLANETARY BODIES IN THE SOLAR SYSTEM USING NEWTONIAN MECHANICS

ABSTRACT

The need to understand black hole formation, property and absorption of other celestial bodies is an interesting issue in Astrophysics and Astronomy. In this short article we avoided complex mathematical difficulty to obtain Schwarzschild’s radius of some planetary bodies, and this radius was computed using Newtonian expression for escape velocity. Results obtained shows that among the planets Jupiter requires a very large amount of gravitational pull to reduce to black hole and was found to be exactly the same with that using Schwarzschild’s metric.

Keywords and phrases: Black hole, Schwarzschild’s radius, Newtonian expression, escape velocity

ABSTRACT

Samples of some commonly used cosmetic products (white powder, brown powder, lipstick, lip gloss and eye liner) were collected and analysed for their lead and cadmium contents using atomic absorption spectrophotometer after digestion. The results obtained showed the presence of lead and cadmium in all the samples, with cadmium ranging from 3.70-6.34mg/kg while lead contents ranged from 0.1-0.19mg/kg. The results also revealed that all the samples have higher concentration of cadmium when compared with the standard of 3.00 mg/kg set up for cadmium in cosmetics by FAO, with lead having concentration of less than 10.00mg/kg set up by FAO in all the samples.

ABSTRACT

Proper integration of all passive strategies as it regards sustainability will be a giant stride to optimizing energy usage in building with absolute mechanical dependant. Passive Design regards the particular way to construct a building using the natural movement of heat and air, passive solar gain and cooling in order to maintain a good internal comfort. Usage of passive strategies in the building sector enhances sustainability measures predominantly through mitigating building’s negative environmental impacts besides optimizing its energy performance. Building a passive home takes careful planning, which includes the introduction of five Basic principles: Orientation, Overhangs and shadings, Insulation, Double or triple glazing, Thermal mass, Through the use of passive solutions it is possible to mitigate, or at least reduce, the use of mechanical systems and the energy demand by a measurable percentage as well as the CO2 emissions. The aim of this paper is to avoid solar radiation, promote ventilation from the prevailing wind and ensure daylight into the building. This journal however demonstrates the importance of an alternative usage of energy in buildings as it regards the sustainable building through careful analysis of related journals, articles, and books. The study is useful for various resource persons involved in construction activities who wishes to imbibe all strategies for the achieving an eco-friendly building.

Obsolescence is commonly regarded as the beginning of the end-of-life phase of buildings. Sources  about  the  life  cycle  of  buildings  show  a  variety  of  terms.  The  building  and development trade commonly refers to the development cycle, consisting of the development phase, including the design and the construction phase, and the usage phase, consisting of the actual  use  and  the  reuse  or  end-of-life  phase  (de  Jonge  and  Arkesteijn,  2008).  Sources regarding the life span, building pathology and mortality of buildings more often refer to the physical life or real life, being the period of physical existence, including the usage and end-of-life phase. This is in line with most national building stock statistics that in general only state withdrawal from  the residential stock, in some countries subdivided by withdrawal  by demolition  and/or  disaster,  merging  with  other  buildings  and  loss  of  function  (Dol  and Haffner, 2010).
