Objective. This study measured light transmission through enamel and dentin and the effect of exposed dentinal tubules to light propagation. Methods. Light attenuation through enamel and dentin layers of various thicknesses (1 mm, 2 mm, 3 mm, and 4 mm) was measured using specimens that were (1) moist and (2) air-dried (n = 5). Measurements were repeated after the specimens were treated with EDT...

Dryland soil chemical properties and crop yields affected by long-term tillage and cropping sequence
Information on the effect of long-term management on soil nutrients and chemical properties is scanty. We examined the 30-year effect of tillage frequency and cropping sequence combination on dryland soil Olsen-P, K, Ca, Mg, Na, SO4-S, and Zn concentrations, pH, electrical conductivity (EC), and cation exchange capacity (CEC) at the 0-120 cm depth and annualized crop yield in the northern Great...
A field trial has been carried out in order to study the use of Earthworm Manure (EWM) and NPK fertilizer improve quality Acid Sulphate Soil (ASS) as a sweet corn (Zea mays L) cultivation land North Sumatra. The experiment was Factorial Randomized Block Design. Factors studied were fertilizer. EWM treatment arranged 4 doses consisting of: Control (0 kg / plot), 0.4 plot; 0.8 1.2 EWM/plot. given...
The trivalent metal ion (M(III)=Cm, Eu)/polyacrylic acid (PAA) system was studied in the pH range between 3 and 5.5 for a molar PAA-to-metal ratio above 1. The interaction was studied for a wide range of PAA (0.05 mg L(-1)-50 g L(-1)) and metal ion concentrations (2x10(-9)-10(-3) M). This work aimed at 3 goals (i) to determine the stoichiometry of M(III)-PAA complexes, (ii) to determine the num...
Background: High concentration of salt makes biological treatment impossible due to bacterial plasmolysis. The present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting pH, salt concentration, reaction time and applied voltage. Methods: The sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...
Arsenic concentration of agricultural soil and surface water used for irrigation were surveyed in two abandoned mining sites Jos South Local Government Area. DB-Zang Dorowa total dissolved solid, hardness, electrical conductivity, temperature pH the determined according to standard procedure. Result indicates that Total dissolve solids W1 was 156±2.00mg/L W2 (160±2.00mg/L), hardness (35.20±4.70...
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...
