Heat and mass transfer in a permeable fabric system used for Personal Protective Equipment (PPE) was investigated using hot air jet impingement conditions to mimic the jet exhaust of Short Take-Off and Vertical Landing (STOVL) aircraft. The STOVL aircraft uses a thrust-vectoring nozzle of the jet engine and a lift fan in order to vertically land and take off a short runaway. The jet engine exha...

Rehabiliating Bushehr historic fabric and paying to it as an important urban fabric through increasing capabilities and facilities is main concern. Bushehr historical fabric can be the consequence of several factors the most important of which is the Persian Gulf and its past history as a national one. This fabric, is organic, dense, compact, having its own characteristics. One of its main prio...

I N T R O D U C T I O N The overall quality of a fabric is dependent on a number of factors, including tensile strength, shrinkage, abrasion resistance, and fabric construction. Also among these is the fabric’s tendency to wrinkle after home laundering – referred to as smoothness. The protocol for ascertaining smoothness grade of a fabric is outlined in the American Association of Textile Chemi...

The present paper reports a detailed study on heat and moisture vapour transmission characteristics of different types of multilayered fabric ensembles. Two sets of multilayered fabrics have been prepared. In first set, two types of carded web produced from acrylic and polyester fibres with five different areal densities in each fibre type have been used as middle layer. In second set, differen...

pay attention to the public transportation, cycling and pedestrian oriented development (pod) and car-free streets can increase the quality of urban spaces and create more secure pedestrians with psychological comfort for human. old urban fabric with hidden physical, historical, and cultural values has been the best evidence of urban identity and meanwhile, the life and growth of this fabric ha...

The IP Multimedia Subsystem (IMS) is an architectural framework for delivering IP multimedia services. The appearance of Software Defined Networks (SDNs) concept in the IMS fabric can unleash the potential of the IMS technology which enables access agnostic services including applications like video-conferencing, multi-player gaming, white boarding all using an all-IP backbone. SDN requires som...

The potential effectiveness of a silver nylon (SN) fabric as an antimicrobial agent was evaluated in a series of in vitro experiments. The results indicated that silver ions from the SN fabric penetrated 2 mm of agar and killed a challenge of 6.9 X 10(7) Pseudomonas aeruginosa, 4.1 X 10(7) Staphylococcus aureus, and 1.4 X 10(7) Candida albicans organisms per cm2 of SN fabric after 24 h of incub...

A meso-scale unit-cell based material model for a prototypical plain-woven single-ply flexible armor is developed and implemented in a material user subroutine for use in commercial explicit finite element programs. The main intent of the model is to attain computational efficiency when calculating the mechanical response of the multi-ply fabric-based flexible armor material during its impact w...

ÐShape fabric and distribution anisotropy of magnetite grains in a highly ferromagnetic (s.l.) syenite are determined for three mutually perpendicular planes on about 600 magnetite grains. The grains are lenticular with an average aspect ratio of about 2.0. Their preferred orientation, determined by the inertia tensor method, is consistent with the principal directions of the magnetic susceptib...
