Let T Bn denote the submonoid of all upper triangular boolean n×n matrices. It is shown by Volkov and Goldberg [6] that T Bn is nonfinitely based if n > 3, but the cases when n = 2, 3 remained open. In this paper, it is shown that the monoid T B2 is finitely based and a finite identity basis for the monoid T B2 is given. Moreover, it is shown that T B3 is inherently nonfinitely based. Hence T B...

The notion that natural disasters can be controlled is, of course, farcical; history is permeated with examples of countless failed attempts at this pointless task; it is synonymous with trying to build a perpetual motion machine. Nonetheless, there are ways to reduce their impact on human communities, particularly by looking away from the normal hypothesis. In a press conference on the remnant...

This article deals with geographical conditions in terrain and their effect on the movement of vehicles, their effect on speed and safety of movement of people and vehicles. Finding of the optimal routes outside the communication is studied in the Army environment, but it occur in civilian as well, primarily in crisis situation, or by the provision of assistance when natural disasters such as f...

The transition to Commander-centric network-enabled Command and Control (C2) is well underway within the US Army and Department of Defense (DOD). The foundation of this approach is an information superiority-enabled concept of operations that describes the way U.S. forces organize and fight in the information age. The idea is to translate this information superiority into combat power by effect...

Although military men have heavier drinking patterns, military women experience equal or higher rates of dependence symptoms and similar rates of alcohol-related problems as men at lower levels of consumption. Thus, gender may be important for understanding substance use treatment (SUT) utilization before deployment. Military health system data were analyzed to examine gender differences in bot...

The position of battle captain in United States Army battalions involves responsibility for tracking a large quantity of information, communicating important information to the right people, and making decisions quickly when events deviate from plans. Soldiers assigned as battle captain in maneuver battalions have a wide variation in background and experience, yet rarely receive specific traini...

This is the Second Edition of Lt.-Col. Hehir's book and is prefaced by a note from Sir O'Moore Creagh, the Commander-in-Chief in India. It is far and away the most useful book on Indian Military Hygiene that we have ever read and should be in the hands of all Medical Officers of the Army. It is so complete and thorough that it is difficult to give a full account of it, but in order that our rea...
