High-dose monophasic preparations are indicated for the management of dysfunctional uterine bleedings and when persistent breakthrough bleedings occur with low-dose oral contraceptives. The monophasic combinations are taken in a fixed dose combination once daily over 21 or 22 days, followed by an interval of 7 or 6 days. 

In perovskite-type catalysts the formation of the final phase is completed already at 973 K. XRD and skeletal FTIR/FTFIR data for LalCol, LalMnl and LalFel calcined at 973 K evidence that only LalFel-973 is actually monophasic and consists of a perovskite-type phase with orthorombic structure. A perovskite type phase with hexagonal-rombohedral structure represents the main phase of LalCol-973, but traces of C03O4 and La2C05 are also present. In the case of LalMnl-973 two phases have been detected both with perovskite-type structure, one orthorombic and the other rombohedral. The calculated cell parameters of the dominant perovskite-type phase are reported in Table 1 for the three samples. The results compare well with those reported in the literature [JCPDS 37-1493, 32-484, 25-1060] which refer to similar samples prepared via solid state reartion. All the perovskite-type samples are markedly sintered...

Lin and coworkers disclosed that, at room temperature, nonenzymatic chemical addition was still observed in a water-organic solvent biphasic reaction system, though the volume of aqueous phases was relative small. Lin developed a method of preparing an active enzyme meal that contained essential water to retain its power for catalysis and found a new catalytic reaction system by application of the prepared meal in a nonaqueous monophasic organic medium (Figure 5.7). There was no problem over a wide range of temperature (from 0-30 °C) when the reactions were carried out under micro-aqueous conditions [50]. 

The risk of development of deep vein thrombosis was found to be 2 to 5 times higher with low-estrogen, desogestrel-containing OCs than with second-generation monophasic and triphasic preparations. 

These materials have been prepared both by hydrolysis of the alkoxides [100] and by coprecipitation from soluble salts of the constituents by using N H4O H or (N H4)2CO3 as precipitating agent [106]. Monophasic samples with surface areas in the range 10-15 m g have been obtained upon calcination at 1300 °C [100, 106].

Effect of the Transition Metal Ions - Hexaaluminate materials, 1 >19, including transition metal ions in the structure (M = Mn, Fe, Cr, Co, Ni) were prepared both via the alkoxide15 and the coprecipitation route.23,24,25 For all the compositions investigated, monophasic samples with layered-alumina structure and surface area in the range 10-15 m2/g were obtained upon calcination at 1300 °C. 

The undoped catalyst was prepared from the monophasic crystallized Ni Alj alloy (ref. 7). The molybdenum and chromium promoted catalysts were prepared from alloys with the composition N -x x where M = Mo (0.05 x 0.4) and M = Or (x - 0.07 or 0.11) (ref. 8). The catalysts were then prepared as described previously (ref. 9), by leaching the crushed alloys in a 6N sodium hydroxide solution at boiling temperature. The catalysts were kept under a molar solution of NaOH. 

The use ofhydrothermal-like synthesis for the preparation of Mo/V/Al/O catalysts, starting from Anderson-type polyoxometalates, leads to monophasic crystalline compounds, also containing other trivalent elements (Fe, Ga), and dopants [13]. For example, the incorporation of Ti in Mo/V/Al/O gives rise to the formation of a compound having stoichiometry Mo6V2Al1Ti0 5Ox, in which the addition of Ti improves the activity with respect to the undoped system. 

Figure 4 shows that some of the synthetic preparations exhibit lethal toxicity and/or pyrogenicity. Compared to lipid A, however, the effective doses of the synthetic preparations for lethality and pyrogenicity were ca. 1000 and 100 times higher. Obviously, there is a separation of activities Preparation 302 is pyrogenic, but not lethal, while preparations 314 and 315 are lethal, but not pyrogenic. Furthermore, preparation 316, which could be directly solubilized in water, was toxic to galactosamine-treated mice in a dose of 50 pg/mouse. With this dose, a low monophasic fever curve was seen in rabbits. In contrast,... 

The initial silica sol consisted of 11 ml of tetramethoxy silane (TMOS), 5 mL of distilled water, and 1 drop of 12 N HC1. A monophasic solution was prepared by the sonogel method 9). Under continuous sonication, a total of 30 ml of tetraethoxy silane (TEOS), 7.5 mL of distilled H2O, and 11 mL of TMOS were addded in a dropwise fashion to form the precursor solution. The final silica sol was composed of a 1 1 5 mole ratio of TEOS TMOS H2O. The acid catalyst was present as a...
