High insensitive

Treatment of the isomeric l,3a,4,6a- (220) and 1,3a,6,6a- (91) dibenzotetraazapentalenes with mixed acid or fuming nitric acid forms z-TACOT (225) and y-TACOT (231), respectively. 438 z xaCOT (225) and y-TACOT (231) are highly insensitive to impact and electrostatic charge and exhibit extremely high thermal stability (ignition temperature 494 °C, DTA curve 354 °C). 

Later, Timson and Short started systematic experiments to test the resistance of bacterial spores, and tried to inactivate them completely to obtain a total sterilization. These authors studied the behaviour of spores under a high-pressure treatment with a long residence time at constant pressure in a range of temperature between - 25°C and 95°C. They noted the high insensitivity to pressure of the spores compared to vegetative forms [8].

As currently practiced risk assessment is conceptually sound, but the uncertainties are great because of gaps in fundamental knowledge. Research into underlying mechanisms of toxicity, as they bear on knowledge of dose-response relations at low dose, is critical to further advances in this field. Clearly the highly insensitive research tools we now have cannot be relied upon Indefinitely as the basis for these important public health decisions. 

Homonuclear correlation spectroscopy (COSY) offers a way to identify spin-coupled pairs of nuclei, even when structural information for the specific molecule under study is completely lacking. Correlation is established using homonuclear coupling, so the technique essentially shows the same information in one plot as in ID homonuclear decoupling experiments. A potentially useful application for this class of analysis is the spin-spin correlation of C- C, but there are two main problems with this approach. The first one is related to the need of the presence of C nuclei in two adjacent atoms. In natural abundance, this probability is too low, so the experiment is highly insensitive and suitable only for concentrated samples rich in carbon content. The second one relates to the relative weakness of the spin-coupled peaks from C- C pairs when compared with the peaks from isolated C nuclei. 

In this connection, the problem of prevention of accidental firing by means other than selection of highly insensitive chemicals can only be touched upon. It consists in the use of filters, shielding, or use of int ral attenuators in the form of special composition headers made from phosphalized carbonyl iron powder. None of the proposed systems of x otection is satisfactory in all respects. 

When silica glass is heated to 1750K, it becomes plastic and can be worked in an oxy-hydrogen flame. Silica glass apparatus is highly insensitive to thermal shock owing to the low coefficient of thermal expansion of silica. Borosilicate... 

They are highly insensitive to poisoning from sulfur-containing compounds. 

Numerical calculations gave the evidence that the stationary value of X is highly insensitive even to a ten-fold increase of the input concentration 7, i.e. the system simulates homeostatic control behaviour. 

Ochsenfeld and coworkers have compared the sensitivity of ab initio methods against empirical methods in calculations of NMR chemical shifts from molecular structures of several prototypical peptides. They find that although simple empirical models can give rather good agreement with experimental results they are highly insensitive for structural (and electronic) changes. On the other hand the cheap empirical methods are continuously improved while ab initio are not feasible at all to use. Ab initio methods can also be used to improve the empirical methods same way as it is done for the empirical force fields.
