MATERIALS AND METHODS 1 μm (B) (A) Electrospinning of PVAG nanofibers.
Figure 1.
The spectrum for gelatin granules prior to electrospinning shows that the band is formed by four individual peaks; situated at amide-A and free water (3282 cm-1), amide-I (1630 cm-1), amide-II (1547 cm-1) and amide-III (1239 cm-1).

As the parameters of the dry fabric were determined, the kenaf yarns were self-woven into plain 1/1 (Fig. 1) using “Floor Loom”.
The Vf in form of composites was calculated according to the equation (1) [7]: Vf = n.m ÷ ρ.h (1) Where n is the fabric ply number in the composite, m is the areal density of the fabric, ρ is the density of the fiber (1.2g/cm3 [8]) and h is the measured thickness of the composite.

Three different panels were produce with different thickness (measured using a caliper); 276tex thickness panel 1.39mm, 413.4tex thickness panel 1.62mm and 759tex thickness panel 2.50mm.

Other characteristics are listed in Table.1.
When the pulse width is between 1ms and 1.5ms, the motor is in a forward mode; when the pulse width is between 1.5ms and 2ms, the motor is in a reverse mode; and when the pulse width is 1.5ms, the motor stops.

The figure 1 illustrates the total cost corresponding to the retrofit intervention.
· Formulation It is easy to express the expenditures for retrofit and new equivalent building like the following expressions: 1.1Cret/25+ Ins (Retrofit) (1) 1.1Crec/50 (New equivalent building) (2) · Resolution The solving of the problem consists to compare the expression (1) to the expression (2).
(1): Retrofit (2): New equivalent building Ins R Annual expenditures Figure 2.
