For the convergent portion, there is reduction in size and length, but for the divergent
portion, though the size is reduced, the length is larger if the same exit Mach number is to be
achieved at exit, but overall, the length of the nozzle is less than what is obtained when analytical
method is used.

chronic toxicity in male or female rats, even it had protecting the mucosa from diclofenac-induced gastric damage.[6,7,8] Some studies had indicated that polyphenol components isolated from Korea L. japonica T. should have antiinflammatory activity on lipopolysaccharide-stimulated RAW 264.7 cells by reducing proinflammatory mediators expression by suppressing NF-κB and p38 MAPK activities.[9] The water extract of Lonicera japonica shown protective activities against 5 % dextran sulphate sodium-induced colitis via the Th1/Th17 pathway.[10] Ionicerin, a flavonoid isolated from Lonicerae Flos, which had anti-arthritic and antifungal activities, had effect on Candida albicans arthritis in mice by nitricoxide production from macrophages, suppressed T cell proliferation and shift of cellular immunity from Th1- toward Th2-type responses.[11] Flos Lonicera, Radix Platycodon and other herbs had effect on reducing inflammatory injury in a rat model of chronic obstructive pulmonary disease by reduction
Experimental data and analysis In the five solvents including water, 40% ethanol, 70% ethanol, ethyl acetate and n-butyl alcohol, only the ethanol extract of various Honeysuckles had antibacterial activity for Staphylococcus aureus, none had antibacterial activities for Escherichia coli.

In this purpose, silicon nanoparticles (nps) appear to be an attractive candidate for room
temperature single electron memory [4-5] in which addition or subtraction of a single electron can
represent a bit of data.
Sample AI-1 (T=950°C, 30mn under N2 only), which have elongated nanoparticle like AII-1 sample exhibit a quasiexponential reduction of the current to its steady state level suggesting that we are probing the statistically-averaged charging dynamics of a large number of ncs.

Results given in Fig.3 shows at the first sight positive results of sound insulation DnT,w of facade walls or as a case may be windows in ventilation position considering health protection when comparing to above quoted data according to WHO [11] or given in relation to (1), where soundproofing indicator of slightly open window of value Rw = 10 to 15 dB is considered for window.
Following suggestions and facts may contribute to higher level of prevention and reduction of health risk from stress factors in new built residential building in the future: • Concurrence of conflicting requirements at so called hygienic window may concrete pressure for projecting buildings with so called quiet facades [18] and legitimate need to define quiet areas and zones connected with park greenery and better use of anti-noise barrier building in accordance with the mission and objectives of Directive2002/49/EC [10] in urbanism

Statistical Analysis: The data were expressed as the mean ± standard deviation (SD).
However, chain scission of the scaffold irradiated by 50 kGy make macromolecular chains breakdown to occur small molecule segment which begin to decompose at 320°C[11] and the high-energy irradiation in air lead to progressive reduction in molecular weight and eventual degradation to non-polymeric materials to some extent.

In addition to the higher mechanical strength obtained due to the addition of fillers in polymeric composites, there is cost reduction in terms of consumption of resin material.

The degree of development of these defects is currently such that it does not reduce the design load capacity of structures, but their further development will eventually lead to its reduction.

Nano-sized data technogenic waste also allows them to easily be distributed in a matrix binder, which ensures high fullness of the composition [14];
o The complex physico-chemical processes lead to the formation of a hardening system "cement-slurry" crystals with higher activity that contributes to strengthening the contact zone to a greater extent than in case without cement nanosized filler [13].
Where was a reduction of amount of the binder from 5 to 15% due to the introduction of the carbonate slurry and effective replacement filler known as CSP.

So, it reduces the operation time and leads to overall value reduction.
Methodology and Data Collection. 3.1 One Factor at a Time Approach The experiments were conducted by victimization of One-factor-at-a-Time-Approach and L9 mixed level in which, one input parameter is unbroken constant and every one alternative parameters are varied.
