Higgs boson production in association with heavy quarks is one of the most important discovery channels for Higgs particles in the Standard Model and its super-symmetric extension at the LHC pp collider. We review the status of the Higgs boson studies, with particular emphasis on the case bbh and tth production. We present results for the total cross section at Large Hadron Collider (LHC) in both single and double parton scattering mechanism.
To protect humans, devices
and maintain high reliability of electrical equipments, efficient earthing
system has to be provided for residential and commercial buildings. The use of
chemical elements around the electrode of earthing systems reduces the earth
resistance which improves the efficiency of these systems. However, the use of
these elements can’t achieve very small earth resistance especially in the case
of dry clay. In addition, they are expensive and not available all the time.
This paper presents a method that treats the soil with adding the Dead Sea
water instead of the chemical elements to further reduce the earth resistance and
to avoid the expenses of these elements. In our approach, the Dead Sea water is
added to a hole around the electrode with a distance not exceeding 10 cm to
avoid the corrosion layer on the electrode. Practical measurements are
demonstrated to show the efficiency of the proposed approach.
