The study examined the
impacts of crude oil exploitation on the soil environment of Ogoni region and
also identified action plans for the future management of the region. Composite
soil samples were collected at two depths: 0 - 15 cm (surface soils) and 15 - 30 cm (subsurface soils) along different positions of
landscape in the four study locations. Samples were analysed in the laboratory
within 5 days of collection. ANOVA was use ...

In the present work, thermal conductivity of rice
husk (200 μm mesh size) filled epoxy composites has been studied experimentally & numerically. In
this study, a successful fabrication of a rice husk filled epoxy composite with different
filler content is possible by hand lay-up technique. An experimental approach
was used to determine the thermal conductivity of rice husk filled epoxy
composites using Lee’s apparatus. The result ...

This paper provides an extension to an optimal control problem using the negative logarithm of deterioration and spoilage function as total cost. This function must be minimized at the end of planning period depending on the alternative quadratic exponential form. The co-state variable has negative values along the optimal trajectory according to the Pontryagin Minimum Principle (PMP). The different values of this co-state ...

Visceral fat is technically the excess accumulation
of intra-abdominal adipose tissue. This type of fat is stored further underneath
the skin than subcutaneous fat and it’s actually wrapped around major organs,
including liver, pancreas and kidneys. Studies have shown that visceral fat
plays a distinctive and potentially dangerous role affecting hormones function
and it is also associated with ...

Directive 2004/54/EC [1] on minimum safety requirements for tunnels in the trans-European road network sets the bases for establishing an acceptable safety level for tunnel users across EU member states. Furthermore, many EU member states enforce stricter safety requirements for tunnels in their territory. The lack of a methodology for determining design and operating requirements for tunnels leads many times to an expensive over- ...

The paper considers the static pressure of the
environment on the parallel pipe. The environment is elastic and homogeneous bodies. To determine the ambient
pressure, the finite element method is used. An algorithm was developed and a
computer program was compiled. Based on the compiled program, numerical results
are obtained. The numerical results obtained for two to five parallel pipes are
compared wit ...

Background: There are controversies
about the etiology and management of recurrent pilonidal sinus. The numbers of
techniques are testament in treating pilonidal sinus (PNS) and no single
procedure is superior in all aspects. Aim of the study: The aim of this study was to
compare two operative procedures (modified Limberg flap ver ...

Based
on the listed company data of high-tech enterprise of manufacturing industry from year 2012 to 2016, this paper analyzed the no-linear effect of R&D
intensity on firm performance with different ability of R&D achievements
transformation. The empirical
results show that the R&D input intensity has a double threshold effect on
the capability of R&D achievement conversion. When the conversion ability
of R&D achievement is lower ...
