A distance magic labeling of a graph G = (V, E) of order n is a bijection l : V → {1, 2, . . . , n} with the property that there is a positive integer k (called magic constant) such that w(x) = k for every x ∈ V . If a graph G admits a distance magic labeling, then we say that G is a distance magic graph. In the case of non-regular graph G, the problem of determining whether there is a distance...

CONTEXT Hunting continues to be a passion and common pastime for many US citizens, especially in rural areas. Unfortunately, with the large volume of hunters entering the woods each season, hunting injuries continue to be common. OBJECTIVE Review the experience of a level I trauma center during each of Wisconsin's 9-day deer firearm hunting seasons over a 6-year period and identify potential ...

Access to private lands for hunting has been implicated as one factor affecting management of white-tailed deer (Odocoileus virginianus) populations, especially in urban–suburban communities. Our objective was to identify factors influencing suburban landowner decisions to allow hunting and bowhunter willingness to comply with additional requirements imposed by landowners. We surveyed bowhunter...

Magic is “a concept used to describe a mode of rationality or way of thinking that looks to invisible forces to influence events, effect change in material conditions, or present the illusion of change” (Encyclopedia Britannica s.v. magic). “Magic and sorcery are the influencing of events, objects, people, and physical phenomena by mystical, paranormal or supernatural means. The terms can also ...

The rapidly increasing rate at which biological data is being produced requires a corresponding growth in relational databases and associated tools that can help laboratories contend with that data. With this need in mind, we describe here a Modular Approach to a Genomic, Integrated and Comprehensive (MAGIC) Database. This Oracle 9i database derives from an initial focus in our laboratory on ge...

Today's application is to magic! Not the friendship kind, though 1 ; instead, we're going to talk about magic squares, an incredibly old piece of mathematics that we can study using Latin squares. Definition. A magic square is a n × n grid filled with the integers {0, 1,. .. n 2 − 1}, such that • each number is used exactly once in our entire grid, and • the sum of all of the entries along any ...

We define a simple algorithm for creating large numbers of semi-magic n× n squares when n is odd. Special cases of the algorithm can also be used to easily create magic and extra magic (or panmagic) n× n squares when n is odd. The algorithm can also create extremely magic n × n squares when n ≥ 5 is prime. These extremely magic n × n squares have n! standard magic n-element subsets, and these n...

Hunting is a major driver of biodiversity loss, but a systematic large-scale estimate of hunting-induced defaunation is lacking. We synthesized 176 studies to quantify hunting-induced declines of mammal and bird populations across the tropics. Bird and mammal abundances declined by 58% (25 to 76%) and by 83% (72 to 90%) in hunted compared with unhunted areas. Bird and mammal populations were de...

Hunting is a historically constructed cultural act and continues to be a passion and a popular recreational pastime worldwide. Along with a high population density in Europe and a large volume of hunters hunting injuries such as falls from hunting stands continue to occur regularly and are a significant cause of morbidity among hunters. The purpose of this study was to review typical injury pat...
