We find a formula, in terms of n , d $n, d$ and p $p$ for the value F $F$ -pure threshold generic homogeneous polynomial degree $d$ $n$ variables over an algebraically closed field characteristic . also show that every all ⩾ 4 $d\geqslant 4$ not divisible by there always exist reduced polynomials k [ x y ] $k[x, y]$ whose is truncation base expansion 2 $\frac{2}{d}$ at some place; particular, f...

All existing models to forecast the corrosion performance of reinforced concrete structures exposed chloride environments are based on one common theoretical concept, namely, a threshold, as sharply defined trigger for corrosion, followed by period active corrosion. We critically review resulting treatment initiation and propagation two distinct, successive stages. conclude that this concept pr...

Acceptable occupational exposure levels for hundreds of airborne concentrations of dusts, vapors, fumes, and gases have been set by consensus organizations and regulatory bodies for decades. These levels have established tremendous precedent and are tempting reference values in the relatively new field of indoor air quality evaluations where validated criteria are greatly needed. The American C...

Methods which can be used to assess the chloride permeability of various types of concrete in a relatively short time are described. An electrical potential from 60-80 volt DC is applied either between a chloride solution ponded on a slab surface and the top of rebar mat, or between two faces at a core taken from a structure. The amount of chloride and sum of the electrical current which passes...

Developing countries have embarked on the promotion of “ICT access for all” through subsidized Information and Communication Technologies (ICTs), especially in underserviced areas of such countries. The main aim of the “ICT access for all” is to extend the communication services to the large areas of underserviced regions through subsidized communication services. In some instances, subsidies m...

If uniform coding (Gödelization) of potentially infinite sequences of numbers can be performed in PSPACEF, then PSPACE = EXPTIME 6= EXPSPACE = 2-EXPTIME, and, for all p, we have p−EXPSPACE = p+1-EXPTIME; if it can be performed in LINSPACEF, we also have LINSPACE = DTIME(2); the proof fails, when relativized to oracle-TM’s. A by-product of this research is that PTIMEF is not closed under number-...
