Acid rain still poses a global problem today, exerting many adverse effects on man, animal, and materials. As its research question, the present study tries to find out whether or not acid rains exist in Akure, Nigeria. For so doing, it determines physico-chemical properties of rain water samples, namely pH, temp, Electrical Conductivity (EC), TDS, acidity, SO4-, NO2-, Cl-, and Free CO2. Accord...

quinazolinone backbone is present in a large number of bioactive substances. since remarkable cytotoxic activity is associated with some 4(3h)-quinazolinones, in this study some 4(3h)-quinazolinone were synthesized and screened against hela cells. the synthesis was performed via reaction of anthranilic acid with dicarboxylic anhydrides to produce carboxylic acids derivatives. the products were ...

The paper describes the performance analysis and of design piezoresistive pressure sensorusing simulation technique. The piequ resistors are arranged in the wheat stone bridge configuration to achieve higher voltage sensitivity and low temp sensitivity The MFMS has been designed and simulated using MATLAB.This paper also discuses the simulations and the response from the MEMS.

Purpose The purpose of this paper is to compare online labor platforms (OLPs) such as Upwork, Fiverr, YoungOnes and Temper with traditional temp agencies. At a first glance, OLPs agencies strongly resemble each other while they aim meet the need for short-term organizations. authors ask question how these market intermediaries differ on issues information technology usage, ways supply demand ar...

[1] The ∼2500 km long Himalayan arc has experienced three large to great earthquakes of Mw 7.8 to 8.4 during the past century, but none produced surface rupture. Paleoseismic studies have been conducted during the last decade to begin understanding the timing, size, rupture extent, return period, and mechanics of the faulting associated with the occurrence of large surface rupturing earthquakes...

Background: The notion that weather conditions may influence the symptoms and course of rheumatic musculoskeletal diseases goes back to ancient times. However, despite seemingly obvious relationship, previous studies assessing how meteorological variables affect pain disease activity have yielded contradictory results. Objectives: To evaluate whether in patients with rheumatoid arthritis (RA). ...

BACKGROUND This study was designed to evaluate the retentive strength of 7 different luting agents on cement-retained implant abutment/analog assemblies. METHODS Fifty-six Steri-Oss implant abutment/analog assemblies and cast superstructures were randomly divided into 7 groups: definitive cements included zinc phosphate cement, Advance, All-Bond 2, Panavia F, and Durelon, while provisional ce...
