  • Physical Aspects Of Atrium

    1417 Words  | 6 Pages

    Atrium was considered as a ‘sun room' back in the old times. These days sun rooms appears in many homes where people want to soak up sun rays in the middle of winter or maybe grow plants year round. An atrium is an open-roofed part of a building, though now it more commonly has a glass roof. Although the atrium has evolved throughout the centuries, the basic design has remained the same. The word atrium comes from the Latin and refers to an open central court. An atrium in architecture is a central

  • The Similarities and Differences Between a Mesopotamian ‘Courtyard’ and a Roman ‘Peristyle’ House

    The similarities and differences between the design, construction and environmental performance of a typical Mesopotamian ‘courtyard’ and a Roman ‘peristyle’ house The idea of courtyard goes back to Neolithic Times. It was conceived for such needs as providing protection from natural forces : weather, wild life or human invasions. Later on, it was transformed in functional architecture that can be characterized by its design, structure and environment uses. Apart from its climatic functions,

  • Heart and Right Atrium

    2140 Words  | 9 Pages

    The heart is a hollow muscular organ that pumps blood throughout the blood vessels to various parts of the body by repeated, rhythmic contractions. It is found in all animals with a circulatory system, which includes the vertebrates. The adjective cardiac means "related to the heart" and comes from the Greek καρδιά, kardia, for "heart". Cardiology is the medical speciality that deals with cardiac diseases and abnormalities. The vertebrate heart is principally composed of cardiac muscle and connective

  • The Height Of The Atrium And Exhaust Fans Locations Effects On The Smoke Management

    1259 Words  | 6 Pages

    height of the atrium and exhaust fans locations effects on the smoke management in atrium. The 2 numerical experiments geometries for named NA & NB as per Figures 2.2 and 2.3. There are 2 openings of (5x5 m) at the 1st floor for air inlet, and 8 extraction fans with discharge capacity 20 m3/s each located at the smoke reservoir. Each floor has a (10x60 m) floor plate on both sides with central opening forming the atrium and the smoke reservoir. The experiment NA is a 5 floor atrium of 30m high and

  • The Between The Atrium Aspect Ratio Under Different Heat Release Rate Of Fire

    1798 Words  | 8 Pages

    Numerical experiment N.B with fire at atrium at 250 Sec [9] Figure ‎2.7 Physical model P.M with fire at atrium at 250 Sec. [9] It was concluded that the height of the atrium and the fan locations have obvious effect on the efficient abstraction. Atrium with height more than 30 m with exhaust fans located towards the ends may require attention to control the smoke abstraction efficiently. Yi, Hou, Li and Feng & Chow [13] study the relation between the atrium aspect ratio under different heat

  • A Report On Fire Protection Engineers

    1744 Words  | 7 Pages

    Chapter 1 1 INTRODUCTION 1.1 General Over the last few decades, large undivided volume buildings such as atrium buildings, covered shopping malls, and airport terminals have become increasingly popular. Atria are one of the modern building features that have been developed by architects and connecting more than 2 or three floors closed at the top to provide attractive space for the occupants. However atria present a big challenge for fire protection engineers as the automatic sprinkler system may

  • A Study On Smoke Management System

    1798 Words  | 8 Pages

    1 LITERATURE REVIEW 1.1 Introduction Buildings with atrium are big challenge for smoke ventilation system, because if fire is initiated in atrium by any different causes at any level of atrium where there is amount of fuel to maintain steady heat release rate, there is probability that the fire will be maintained. Study fire development, smoke layer, temperature distribution and carbon monoxide concentration is complicated and unstable. Therefore, computational fluid dynamics is useful tool to

  • Sheep Heart Dissection

    four-chambered heart, just like humans. By studying the anatomy of a sheep's heart, you can learn about how your own heart pumps blood through your body and keeps you alive!. Procedure Observation: External Anatomy Most heart diagrams show the left atrium and ventricle on the right side of the diagram. Imagine the heart in the body of a person facing you. The left side of their heart is on their left, but since you are facing them, it is on your right. 1. Identify the right and left sides

  • The Cardiac Cycle Is Vital For Proper Cardiovascular System Function

    776 Words  | 4 Pages

    valves, the lower two chambers of the heart are called ventricles. Atrioventricular valves: a valve between an atrium and ventricle of the heart. Vena cava: the two largest veins in the body, carry de-oxygenated blood from various regions of the body to the right atrium of the heart. SA node: The sinoatrial node is a section of nodal tissue located in the upper wall of the right atrium. Sets the rate of contraction for the heart. Spontaneously contracts and generates nerve impulses that travel throughout

    A Historical Survey of Architecture and Urbanism: from Antiquity to the Middle Ages The Houses of Roman Italy Introduction This paper evaluates the design and structures of the Roman houses since the antiquity era to the Middle Ages. The paper digs deep into the houses that the Romans built and compares several factors that give relative argument base for the entire paper. It is outlined that most Roman houses were built in respect to the wealth and influence of individuals within the society. This
