Abstract:
The purpose of this study is to analyze accidents occurring in the Swedish construction industry, focusing specifically on the situation in the individual trades. The article includes all occupational accidents with at least 1 day of absence from work that were reported to the Swedish Social Insurance Agency for the year 2016. The results, focusing on accident cause, injured body parts as well as accidents per weekday, month and age, show that although the trades share commonalities regarding occupational accidents, a number of trade-specific problem areas stand out. With this in mind, conclusions are drawn regarding the situation in each respective trade and suggestions are made for future studies focusing on accidents in construction industry trades.

Construction of Root Locus
For positive gain values, the root locus exists on the real axis to the left of an odd number of finite open-loop poles or zeros. The root locus starts at the open-loop poles and traces the paths of the closed-loop poles as the gain...
Construction of Frequency Distribution
First, make a table with two columns—one with the title of the data that needs to be organized, and the other column for frequency. [Draw a third column for tally marks if needed]. Then, take a look at the items given in the data set and decide if an ungrouped frequency distribution table or a grouped frequency distribution table would be more suitable. If there are large sets of different values, then it is...

Temperature Dependence on Reaction Rate
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...
