A large body of nonexperimental literature finds residing in a disadvantaged neighborhood is deleterious for mental health, and recent evidence from the Moving to Opportunity (MTO) program—a social experiment giving families living in high-poverty neighborhoods the opportunity to move to low-poverty neighborhoods—suggests a causal effect of moving to a low-poverty neighborhood on adult mental h...

The metallothionein genes of Drosophila melanogaster, Mtn and Mto, may play an important role in heavy metal detoxification. Several different tandem duplications of Mtn have been shown to increase cadmium and copper tolerance, as well as Mtn expression. In order to investigate the possibility of increased selection for duplications of these genes in natural populations exposed to high levels o...

We consider a single stage multi-product manufacturing facility producing a large number of end-products for delivery within a service constraint for the customer lead-time. The manufacturing facility is modeled as a multi-product, multi-priority queuing system. In order to reduce inventory costs, an efficient priority allocation between items consists in producing some items according to a Mak...

To be successful in companies, a production planning and control (PPC) concept should fit to the production environment. Essential elements of the concept should correspond with the characteristics of the production system. For classical concepts such as MRP these elements have become common sense. For example BOMexplosion and constant lead times make MRP known to perform best in environments w...

Delaying product differentiation is a hybrid strategy that strives to reconcile the dual needs of high variety and quick response time. A common product platform is built to stock in the first stage of production (called the Make-To-Stock (MTS) stage) which is then differentiated into different products after demand is known in the second stage (known as the Make-To-Order (MTO) stage). In this ...

Multi-scale topology optimization (MTO) is exploited today in applications that require designs with large surface-to-volume ratio. Further, the advent of additive manufacturing, MTO has gained significant prominence. However, a major drawback it computationally expensive. As an alternate, graded been proposed where design features at smaller scale are variations single microstructure. This lea...

Purpose: The knowledge, attitudes and practice among inhabitants of Mto wa Mbu Division was examined to provide objective information on sparganosis infection. Hence, the study was carried out. Methods: The study was conducted among the inhabitants of Mto wa Mbu Division, Monduli District, Tanzania from January to April 2012. Inhabitants were informed about the objective of the study and invite...

This paper describes the exploration of manufacturing planning and control issues in the capital goods industry using a simulation approach. The companies produce products which have deep and complex product structures and are produced in low volume on an engineeror make-to-order basis (ETO, MTO). The work reported here draws on the results of surveys of companies involved in the manufacture of...

This paper addresses the impact of power devices switching characteristics on design and performance of pulsewidth-modulated current stiff converter (CSC) topologies with resonant snubbers. The MOS turn-off (MTO) thyristors were selected for this study due to their high voltage and current ratings, simplified gate drive circuitry, unity gain turn-off, greatly reduced storage time allowing highe...
