The State of Analytical Instruments in Some Environmental Pollution Control L...IJERA Editor
The state of the environmental laboratories involved in monitoring environmental pollution control in Nigeria has been studied in this research. The research was undertaken by visiting four analytical laboratories involved in environmental pollution control in Nigeria. The analytical laboratories visited are those of Nigerian National Petroleum Corporation (NNPC) Kaduna, Ashaka cement factory, regional laboratory of the Federal Ministry of Water Resources Gombe, and the National Reference laboratory Lagos. In these laboratories results were collected in the laboratories, interviews were carried out and analytical instruments available were documented. It was discovered that, in these laboratories many standard analytical instruments needed for quality environmental pollution control and monitoring are lacking. Comparison of analytical instruments found in these laboratories with those found in literature revealed that many needed analytical instruments are missing. It is the position of this work that the gap between the environmental analytical instruments found in literature and that found in the research laboratories is very large and calls for concern

In the present study, experimental investigation on thermal conductivity of green
nanofluids prepared from coconut fibre-based nanoparticles and suspended in 60:40
ethylene glycol (EG) water (W) mixture was carried out. The measurement of thermal
conductivity was conducted at 15 °C to 60 °C at mass fractions of 0.04 wt%, 0.08
wt%, 0.5 wt% and 1 wt%. The results show deterioration in thermal conductivity with
an increasing temperature. Also the deterioration increased as the mass fraction
increased.

Study on the Most Efficient Method, for Chemistry Laboratories, on the Recove...QUESTJOURNAL
ABSTRACT: Waste management and treatment programs are increasingly relevant, taking into account the global scenario. However, the use of the concept of 3R (Reduction, Reuse and Recycling) still needs to be implemented in university labs. The use of this concept can avoid environmental contamination and thus promote operator and community safety. In this perspective, the present work intends to define an adequate methodology for the reuse of N-heptane used in petroleum analyzes. Methodologies will be compared using rotary evaporator and fractional distillation. The treated residues contained crude oil and n-Heptane, being recovered by fractional distillation under two conditions. In condition 1 a column 80.0 cm long and 6.0 cm in diameter was filled with glass rings and in condition 2 with Raschig rings in stainless steel. The second methodology used a conventional rotary evaporator. The analyzed responses were: the total time of the process, the recovered percentage of n-Heptane and its degree of purity, evaluated by gas chromatography. This study allowed to demonstrate the most appropriate methodology for the treatment of this residue and the economic advantages resulting from the effluent minimization.
This presentation was a plenary talk on environmental forensics delivered at the 2011 Dioxin Conference in Brussels (www.dioxin2011.org). The presentation focused on the topic of environmental forensics investigations and techniques and their application to the field of persistent organic pollutants (POPs).

This paper describes the architecture of second
generation current conveyor (CCCII)and designing an
amplifier using second generation current conveyor. The
designed amplifier through CCCII+ can be used in various
analog computation circuits and is superior in
performance than the classical opamp. It provides better
gain with higher accuracy. The presented approach over
here is to design current amplifiers and voltage amplifiers
using current controlled current conveyor (CCCII). The
second generation CCCII has the advantage of electronic
adjustability over the CCII i.e. in CCCII, the X-terminal
intrinsic resistance can be adjusted througha bias current
is possible. The CCCII has been designed to work both as
current amplifier and voltage amplifier. Various
simulations have been carried out to obtain the desired
results.

Inquiry-based study can enhance long term retention and improve application and synthesis of knowledge. In this research, we provide a student-driven, inquiry-based teaching mode that trains undergraduate as researcher, who can raise questions, design and perform hypothesis-driven experiments, analyze data and discuss results. Before students design their research projects, they should know well and answer a series questions related experiment principle, condition and error control, data detection and processing, which guide them to familiarize with project principles, operations and data processing. Continuous distillation is an ideal choice for the training in an undergraduate lab due to it synthesizing the fluid flow, heat transfer and mass transfer. Students actively participate in the project, because their doubts can be removed through designing and implementing experiments, such as: How to evaluate the separation capacity of the distillation operation? How to implement the experiment and get the component concentration in simple way? How to evaluate the separation capacity of packing column? Students use their acquired research skills to design, execute and analyze experiments independently. While, the instructors only make some adjustments to ensure that the experimenter completes the design goal within the limited experimental time. Results show that distillation experiment builds an open, inquiry-based platform for students, which significantly enhances the ability to apply and integrate knowledge. The scientific research ability and teamwork awareness have also been nurtured.
