In this study, the solid phase FT-IR and FT-Raman spectra of the 2-hydroxy-4-methyl-5-nitropyridine (HM5NP) was recorded in the range 4000–400 cm^–1 and 3500–100 cm^–1, respectively. Theoretical information on the optimized geometry, harmonic vibrational frequencies, Infrared and Raman intensities were obtained by means of density functional theory (DFT) using standard B3LYP/6-311++G** level. This information was used in the assignment of the various fundamentals. Comparison of the simulated spectra with the experimental spectra provides important information about the ability of the computational method to describe the vibrational modes.

This moisture level detector has two alternative power sources (3W, 11.5V solar panel and 9V battery) which supply voltages to the system and then regulated by a 7805IC voltage regulator to 5V required by a programmable hardware (microcontroller) with embedded analog digital converter (ADC). The microcontroller receives information from the probe (sensor) inserted into the soil, processes the information and displays the output on a Liquid Crystal Display (LCD) within few seconds. The moisture contents of four soil samples A, B, C and D (respectively clay soil, loamy soil, sandy soil and silt soil) obtained from different locations were determined using this detector. Samples A, B, C and D respectively showed moisture percentages of 85%, 71%, 43% and 21%. From the obtained results, sample A showed that the moisture level is above average, sample B showed that the moisture level is just average, sample C and D showed that the moisture levels are respectively below average and poor. From the obtained result, clay soil retained more water than other soil samples due to its high water holding capacity. The moisture level detector performed at an efficiency of 85%.

Traditional Rapid Prototyping (RP) is referred to as layered manufacturing free form fabrication. It is used for the physical modelling of a new product design directly from CAD data without the use of any special tooling or significant process engineering. This reduces the lead time required to produce a prototype of product. This paper is related to designing and manufacturing of modified bench vise on rapid prototyping machining process. We have designed the conventional and modified bench vise in Pro-e CAD software and manufactured it on Dimension 1200esRPT machine and analysis is carried out in ANSYS CAE software.

This paper presents a Diode Clamped Inverter for Static Compensator (STATCOM) using Space Vector Pulse Width Modulation (SVPWM) technique. Static Synchronous Compensator (STATCOM), a Flexible Alternating Current Transmission Systems (FACTS) controller .For a given dc bus voltage the maximum inverter line-to-line voltage generated by the SVPWM scheme is 15.5% higher than that by the SPWM scheme. SVPWM scheme is used to reduce the switching losses, by changing switching states such that only single phase voltage changes every time. SVPWM strategy enables balancing voltages of the dc capacitors without using additional devices multilevel (three level) inverter is used to reduce THD in its ac output voltages in comparison to the two-level inverter. In order to achieve reactive power control, by maintaining unity power factor at the source end feeding reactive load by three level diode clamped SVPWM Inverter which is adapted as STATCOM is employed in this paper. The control strategy for the compensation is based on the instantaneous active and reactive power theory The STATCOM is modelled and simulated in MATLAB Simulink environment. The simulation results of STATCOM under balance voltage condition are presented.

Phthalates are toxic for human beings and their toxicity can be expressed in various forms like teratogenic, mutagenic, estrogenic and carcinogenic effects as well as by endocrine disturbances. The most commonly encountered phthalate molecules in the environment are: DMP, DEP, DnBP, BBP, DisoDP, DALP, DNP), DEHP, and DnOP. In order to assess the health and environmental impacts of phthalates, it is necessary to access these compounds at the molecular level in natural systems, including water. Therefore, our study was devoted to setting up a protocol including phthalate extraction step, followed with a development of a HPLC/DAD analysis methodology, using artificial mixtures of different standard phthalate compounds and water standard reference material we made in our laboratory. As results, we obtained good performance characteristics such as detection limits (ranging 1.1 - 40.0 ng/L), limits of quantification (from 3.75 to 134 ng /L), coefficients of variation (CV) lower than 10 %, and quality control cards showing that the HPLC/DAD methodology we developed was under statistical control and suitable for phthalate determination in water.

The problem of historical documentation has been with society since the ages. The response of African societies like Opobo to this trend has been to utilize various artistic mediums like drum language as repository of history. Through this approach the various traditions are passed on through time. This research x-rays the contributions of Drumlore to the rich history of Opobo Kingdom.
