wiener index is a topological index based on distance between every pair of vertices in agraph g. it was introduced in 1947 by one of the pioneer of this area e.g, harold wiener. inthe present paper, by using a new method introduced by klavžar we compute the wiener andszeged indices of some nanostar dendrimers.

The determination of the water chemistry for cooling systems nuclear fusion plants is under debate. It should be tailored different types reactors: either experimental, e.g., ITER, JT-60SA, and DTT, or aimed at power generation, DEMO, given operation requirements. This paper presents dual approach involving experiments computer simulations chosen definition DEMO chemistry. Experimental work was...

The need for predicting pipeline service life and improving risk assessment relating to corrosion hazards requires establishing a correlation between the rate (CR) of steel its coating condition, cathodic protection (CP) levels surrounding soil conditions. This paper presents systematic study CR bare coated—with without dent or holiday defect—X60 in simulated field environments. Three CP scenar...

Static tests of horizontally restrained rocket motors at the ATK facility in Promontory UT, USA result in the deposition of entrained soil and fuel combustion products, referred to as Test Fire Soil (TFS), over areas as large as 30-50 mile (80-130 km) and at distances up to 10-12 miles (16-20 km) from the test site. Chloride is the main combustion product generated from the ammonium perchlorate...

One can take advantage of the striking similarity of ignitable liquid vaporization (or weathering) patterns and the separation observed during distillation to predict the composition of residual compounds in fire debris. This is done with the advanced distillation curve (ADC) metrology, which separates a complex fluid by distillation into fractions that are sampled, and for which thermodynamica...
