Stretchable woven chute is a safe device for falling humans from multi-story buildings in emergencies. During the fall, the elastomeric property of the fabric, in the weft direction, causes radial forces towards the human body inside .These radial forces lead to frictional forces between the chute and the body. The falling man can reduce the falling speed by exerting outward forces via stretchi...
In Islam the “Tree of Life” is named as Sedreh or Tuba and the followers of Islam believe that this tree is grown in Heaven; therefore it is an interesting subject for artistic innovative. In Turkmen terminology “tree of life” is called “Yashaish bagh”. In this study we have made an effort to evaluate the symbol of the Tree and the “Tree of Life”,...
Two non-woven fixed-bed bioreactors (NFBR) based on different substrates (nitrite and nitrate) were constructed to study the environmental adaptability for temperature and organic matter of anammox-denitrifying system and nitrogen removal performance. The two reactors were successfully operated for 200 days. The average removal rates of nitrogen and COD of R2 were 81% and 93%, respectively. Bes...
Three dimensional (3D) woven composites have attracted the interest of academia and industry thanks to their damage tolerance characteristics and automated fabric manufacturing. Although much research has been conducted to investigate their out-of-plane “through thickness” properties, still their in-plane properties are not fully understood and rely on extensive experimentation. To date, the li...
Interest in geopolymer concrete (GeoPC) and rubberised (RuC) has grown over the past two decades. The former offers an attractive alternative to ordinary Portland cement (OPC) given its environmental footprint, while latter provides a sustainable solution tyre recycling helps mitigate depletion of natural aggregates. benefits combining merits GeoPC RuC form (RuG) as potential construction mater...
Carpet experts consider nobility of a Qashqai rug in properties like use of suitable wool fiber, herbaceous dyeing, mental designing and bald painting. These principles were used in a variety of samples of Qashai tribe’s hand-woven carpets. On the other hand, production system in that period was based on the use of existing sources and facilities and motivated by providing financial suppo...
This paper deals with evaluation of the mechanical properties of woven fabrics. Method of evaluation is concentrated loading system. A total of 17 pieces of woven fabric is used. The most related parts of the curve to the properties are shown and as a result, effective features are lightened up.
the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
Abstract: This paper presents the results of experimental determination of fiber bed permeability variation with porosity. Flow measurement experiments were designed to measure fiber mat permeability for fiber beds with various fiber volume fractions. Woven fiberglass, chopped fiberglass, and carbon fiber mats were used as reinforcements. The effects of reinforcement type and porosity on fiber ...
Accurate imaging of urethral strictures is critical for preoperative staging and planning of reconstruction. The current gold standard, retrograde urethrography (RUG), allows for accurate diagnosis, staging, and delineation of urethral strictures, and remains a cornerstone in the management of urethral stricture disease. In complex situations, the RUG can be combined with voiding cystourethrogr...
