This study aims to identify and analyze the band gap width of carbon phase produced from corncobs mixed with PEG-4000 see surface area corncob phase. First, characterization test was carried out using Scanning Electron Microscope Energy-Dispersive X-ray (SEM-EDX) spectroscopy determine morphology Ultraviolet–Visible (UV-Vis) carbon. Then, adding Polyethylene Glycol (PEG) 4000 at a specific conc...

this study investigated the applicability of polyethylene glycol (peg-4000) coated fe3o4 magnetic nanoparticles for the selective removal of toxic pb (ii) ion from wastewater. the fe3o4 magnetic nanoparticles of 24 nm were synthesized using a coprecipitation method and characterized by scanning electron microscopy (sem), vibratingsample magnetometer (vsm), and x-ray diffraction (xrd). sem image...

BACKGROUND: Depression is a widespread, global problem, increasingly linked with vitamin D deficiency in the literature. However, knowledge gap persists regarding relationship between depressive symptoms and intake. OBJECTIVE: To determine association supplementation adults (aged 18+ years). METHODS: This study consists of systematic review meta-analysis randomized controlled trials (RCTs), pub...

In addition, a factor of F75 discovered by Gary Gostin is presented. The current status for all Fm is shown in a table. Primes of the form k ■ 2" + I, k odd. are listed for 31 =£ k < 149, 1500 < n « 4000, and for 151 « k « 199, 1000 < n « 4000. Some primes for even larger values of n are included, the largest one being 5 • 213'65 + 1. Also, a survey of several related questions is given. In par...

The age range was between 3 1/2years and 66 years. The total white ceIl count range was 4000 per c.mm. to 23400 per c.mm. 52 cases (52%) had a ceIl count of more than 10000 per c.mm. while in 48 cases (480/0) the leucocyte count was below 10000 per c.mm. The lowest count of 4000 . per c.mm. was seen in a case of acute appendicitis with free pus (grade 2) and the highest count of 23400 per c.mm....
