Recent progress reveals that, in the methanol-to-olefin (MTO) process on acidic zeolites, the conversion of an equilibrium mixture of methanol and DME is dominated by a "hydrocarbon pool" mechanism. However, the initial C-C bond formation, that is, the chemistry during the kinetic "induction period" leading to the reactive hydrocarbon pool, still remains unclear. With the application of a stopp...

Experimental estimates from Moving to Opportunity (MTO) show no significant impacts of moves to lower-poverty neighborhoods on adult economic self-sufficiency four to seven years after random assignment. The authors disagree with Clampet-Lundquist and Massey’s claim that MTO was a weak intervention and therefore uninformative about neighborhood effects. MTO produced large changes in neighborhoo...

The effect of a Make-To-Order (MTO) production strategy on the applicability and impact of Enterprise Resource Planning (ERP) systems is investigated through a mixed method approach comprised of an exploratory and explanatory survey followed by three case studies. Data on Make-To-Stock (MTS) companies is also collected as a basis for comparison. The exploratory data demonstrates, for example, t...

The research into multi-product production/inventory control systems has mainly assumed one of the two strategies: Make-to-Order (MTO) or Make-to-Stock (MTS). In practice, however, many companies cater to an increasing variety of products with varying logistical demands (e.g. short due dates, specific products) and production characteristics (e.g. capacity usage, setup) to different market segm...

In this paper a demand time series is analysed to support Make-To-Stock (MTS) and Make-To-Order (MTO) production decisions. Using a purely MTS production strategy based on the given demand can lead to unnecessarily high inventory levels thus it is necessary to identify likely MTO episodes. This research proposes a novel outlier detection algorithm based on special density measures. We divide th...

POMS 22 nd Annual Conference Reno, Nevada, U.S.A. April 29 to May 2, 2011 Abstract: MTS-MTO system is suitable where standard modules are shared by various finished products through divergent finalization. The system can satisfy product variety by taking advantage of flexibility of MTO, but its performance is lowered when the capacity is constrained. One way of dealing with the problem without ...

Methylrhenium trioxide (MTO) has the rare ability to stoichiometrically generate methanol at room temperature with an external oxidant (H2O2) under basic conditions. In order to use this transformation as a model for nonredox oxidative C-O coupling, the mechanisms have been elucidated using density functional theory (DFT). Our studies show several possible reaction pathways to form methanol, wi...

A new myeloid cell line, MTO-94, was established from the bone marrow of a patient with myelodysplastic syndrome (MDS). MTO-94 cells matured in culture medium without the addition of growth factors, and yielded neutrophils with pseudo-Pelger Huët anomaly or hypersegmentation until 6 months. Ten months after the start of cell cultivation, MTO-94 consisted of myeloblasts. Surface phenotypes were ...

In small-pore zeolite catalysts, where the size of the pores is limited by eight-ring windows, aromatic hydrocarbon pool molecules that are formed inside the zeolite during the Methanol-to-Olefins (MTO) process cannot exit the pores and are retained inside the catalyst. Hydrocarbon species whose size is comparable to the size of the zeolite cage can cause the zeolite lattice to expand during th...
