ABSTRACT

This research examines the physical helth care environments and explores how to utilize (indoor water features) for regenerating people spirit. Although much research supports the idea that natural elements may help alleviate stress and anxiety, but bringing nature into the public interior spaces is problematic. There is a lack of research about the relationship between the helth care physical spaces, stress, and indoor water features. This study investigates how to utilize (indoor water features) in the helth care public spaces that may help reduce stress potential. The absence of a comprehensive theoretical framework for the role of water feature as an effective restorative element that may reduce stress by providing a pleasant affect, and exploring its implicit psychological aspects constitutes the main research problem. In view of the problem under investigation, the goal of the present research is defined to arrive at the identifying of the main strategies to reduce stress potential by using indoor water features in the public helth care spaces. Arriving at the aforementioned aim requires building a theoretical framework, and then the application of the framework to selected interior helth care spaces images (with various water features) in order to test the validity of the hypothesis. Finally research findings, a set of recommendations are put forward.

Keywords: Water features, anxiety and stress, public waiting spaces, health care buildings.

ABSTRACT

This paper presents the results of study conducted with artificial neural networks (ANN) to determine the effects of the variations of concrete constituents on ultrasonic pulse velocity (UPV) and developed mathematical model to predict the compressive strength of concrete. The proposed input parameters are major factors that affect (UPV), such as cement content, water–cement ratio (W/C), the aggregate–cement ratio (A/C), maximum aggregate size, and age of concrete. The output parameter is the (UPV). The results show that (UPV) increased with the increase in concrete age. Increasing the cement content caused a rapid pulse in velocity readings, and (UPV) increased with the increase in maximum aggregate size. Aside from these factors, (W/C) negatively affected pulse velocity. Also, the ANN model was built to predict the compressive strength of the concrete using pulse velocity and the age of concrete. The results showing good rapprochement between experimental value of compressive strength with predicated value of compressive strength.

ABSTRACT

The Place as a cosmic reality perceived by humans during his daily life unlimited in being visually static aware which filled the thinkers and philosophers ,And despite of the predominance of stillness and strap on the place where those in ancient times but that art in General and particular narrative grant place is clear and effective especially in our present time ,There are a lot of terms which approach to the place some related on mention the word ( place ) as equivalent attached or containment or similar approach and some other are including: extension, environment, space, emptiness, position and others of which referred to by specialists. Thus the research problem (lack of cognitive framework for spatial systems role in shaping the architecture) therefore the research aims to create a knowledge base for spatial systems role in shaping the architecture. Because there is an important role search is supposed to place systems outside the field of architecture and the potential impact on the field of architecture, and that there is an effect of the event in the system and its relationship with the place. So the search will focus on studying the concept of place within the field of (Quran – language – geographic literature. meeting – philosophy – engineering) and their relationship to the formal configuration of architecture systems.

ABSTRACT

Internal curing has become a modern technology holds promises for making a durable mortar and decreasing early-age cracking. Since mortar service life is a crucial factor of providing sustainable structures, internal curing can provide a distinct contribution to increase the sustainability of our nation’s building. This study shows results of an experimental investigation of using crushed brick waste (CBW) in cement mortar mixtures prepared by substituting sand by some percentages (5, 10, 15, 20 and 25%) of (CBW). Three curing regimes were adopted in this study: water curing by immersing specimens in water for 28 days, partially water curing by immersing specimens in water for 3 days and left them in laboratory for 24 days and air curing in laboratory for 28 days without immersing samples in water to recognize an ideal methodology for determining whether a given (CBW) can be used for internal curing in cement mortar. Fresh density, hardened density, compressive strength, water absorption, and modulus of rupture were tested. Results indicated that fresh and hardened density, compressive strength and modulus of rupture were decreased with the addition of (CBW). However, they were higher for mortars cured in air conditions than those cured in water and partially water curing. Water absorption was increased with the increase of (CBW). It was demonstrated that air cured mortar give good results for mechanical properties as compared with water cured mortar, hence (CBW) can be used for internal curing in cement mortar especially in finishing works.
