Nitroguanidine - sometimes abbreviated NGu - is a colorless, crystalline solid that melts at 257 °C and decomposes at 254 °C. Nitroguanidine is an extremely insensitive but powerful high explosive. Nitroguanidine is an extremely insensitive but powerful high explosive.
Difficulty due to the person performing the task and the environment (e.g. two individuals, a major league pitcher and an inexperienced ball thrower, are asked to throw a baseball as fast as they can to first base on two days, one on a sunny day and the other on a windy day).
Idle Woman, painting by Daniel Hernández Morillo. Idleness is a lack of motion or energy. In describing a person, idle suggests having no labor: "idly passing the day". In physics, an idle machine exerts no transfer of energy. When a vehicle is not in motion, an idling engine does no useful thermodynamic work.
Amongst the collection of tools, the Rushmore Drilling Index and Rushmore Drilling Index & Estimated Drilling Days, both designed and owned by the company, are particularly noteworthy. Designed as objective tools for well planning, they index the difficulty and indicate the amount of time a planned well is likely to take to drill to target depth.
The Non-Covalent Interactions index, commonly referred to as simply Non-Covalent Interactions (NCI) is a visualization index based in the Electron density (ρ) and the reduced density gradient (s). It is based on the empirical observation that Non-covalent interactions can be associated with the regions of small reduced density gradient at low ...
The Home Buyer Index in Franklin County, Ohio, where Columbus is primarily located, shows difficulty has increased steadily since the beginning of 2020, rising from 39.5 in December 2020 to 74.0 ...
Youden's index is often used in conjunction with receiver operating characteristic (ROC) analysis. [3] The index is defined for all points of an ROC curve, and the maximum value of the index may be used as a criterion for selecting the optimum cut-off point when a diagnostic test gives a numeric rather than a dichotomous result.
The ideal difficulty therefore depends on individual player and should put the player in a state of flow. [6] [4] Consequently, for the development, it can be useful or even necessary to focus on a certain target group. Difficulty should increase throughout the game since players get better and usually unlock more power.
