The cost and effectiveness of two bed bug (Cimex lectularius L.) integrated pest management (IPM) programs were evaluated for 10 wk. Sixteen bed bug-infested apartments were chosen from a high-rise low-income apartment building. The apartments were randomly divided into two treatment groups: diatomaceous earth dust-based IPM (D-IPM) and chlorfenapyr spray-based IPM (S-IPM). The initial median (...

This paper briefly described the general production of intelligent agricultural machine in precision agriculture. It summarized the basic principle and the application in precision agricultural demonstration field of those agricultural machines, which mainly included wheat variable ferti-seeder, yield distribution information acquiring system, variable controlled large irrigation system moving ...

In this paper, the Chebyshev spectral collocation method(CSCM) for one-dimensional linear hyperbolic telegraph equation is presented. Chebyshev spectral collocation method have become very useful in providing highly accurate solutions to partial differential equations. A straightforward implementation of these methods involves the use of spectral differentiation matrices. Firstly, we transform ...

The central part of historic cities is developed by ordinary residential buildings that do not correspond to the current architectural and functional requirements building codes, therefore require comprehensive reconstruction. Therefore, it essential explore types development in state planning structure apartments, which will allow for professional restoration future. purpose this research was ...

In each precinct, we identi ed addresses and apartments in which unregistered and misregistered citizens were likely to reside as follows. We rst collected the list of citizens registered at the precinct as of January 2011 and ordered it by address. Between May and September 2011, surveyors went to each address and wrote down names found on the mailboxes or on intercoms and the corresponding ap...

We provide a basic formal framework for the theory of chamber complexes and Coxeter systems, and for buildings as thick chamber complexes endowed with a system of apartments. Along the way, we develop some of the general theory of abstract simplicial complexes and of groups (relying on the group add class for the basics), including free groups and group presentations, and their universal proper...
