Metoprolol tartrate USP is a white, practically odorless, crystalline powder with a molecular weight of 684.82. It is very soluble in water; freely soluble in methylene chloride, in chloroform, and in alcohol; slightly soluble in acetone; and insoluble in ether. Inactive Ingredients: Tablets contain cellulose compounds, colloidal silicon dioxide, D&C Red No. 30 aluminum lake (50-mg tablets), FD...

Most integrated circuit interconnects are principally composed of a few metals , including aluminum alloyed with copper, tungsten, titanium, Al 3 Ti, and Al 2 Cu, in a silica matrix. Integrated circuit interconnects have recently been proposed as a candidate system for visualization by computerized microto-mography using absorption in the soft X-ray region. In this work, we demonstrate the feas...

increases over controls were found when root segments were incubated in phosphorus solutions containing 10-3 A D)NP ancd at lowx temlperatture. The increased Pi in Al-roots did niot result in an increase in the total amounit of l)hosphorus incorporated into phosphorylated compounds. Aluminum treatnment miiarkedly decreased the incorporation of P32 into sigar phosl)hates but increased the pool s...

Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of...

The effects of different aluminum species on malate dehydrogenase (MDH) activity were investigated by monitoring amperometric i-t curves for the oxidation of NADH at low overpotential using a functionalized multi-wall nanotube (MWNT) modified glass carbon electrode (GCE). The results showed that Al(III) and Al(13) can activate the enzymatic activity of MDH, and the activation reaches maximum le...

Six new intermetallic aluminum silicides--Gd(2)PtAl(6)Si(4), Gd(2)AuAl(6)Si(4), Tb(2)PtAl(6)Si(4), Tb(2)AuAl(6)Si(4), Dy(2)PtAl(6)Si(4), and Dy(2)AuAl(6)Si(4)--have been obtained from reactions carried out in aluminum flux. The structure of these compounds was determined by single-crystal X-ray diffraction. They form in space group Rthremacr;m with cell constants of a = 4.1623(3) A and c = 51.0...

Two-week-old soybean (Glycine max) plants were subjected to factorial combination of five levels of aluminum chloride (0, 50, 100, 200 and 300 μM) and three levels of indoleacetic acid (IAA) (0, 50 and 100 μM). In the absence of IAA, treatment with increasing levels of Al progressively decreased net assimilation rate (NAR) and leaf water content per unit area (LWCA), but it increased the antiox...

Laminated aluminum foils are increasingly being used to protect drug products packaged in semipermeable containers (e.g., low-density polyethylene (LDPE)) from degradation and/or evaporation. The direct contact of such materials with primary packaging containers may potentially lead to adulteration of the drug product by extractable or leachable compounds present in the closure system. In this ...
