BACKGROUND We examined the introduction of diphtheria-tetanus-pertussis (DTP) and oral polio vaccine (OPV) in an urban community in Guinea-Bissau in the early 1980s. METHODS The child population had been followed with 3-monthly nutritional weighing sessions since 1978. From June 1981 DTP and OPV were offered from 3months of age at these sessions. Due to the 3-monthly intervals between session...

In order to extend the antibacterial time of quaternary phosphonium salt in bacteria, palygorskite (PGS) is used as the carrier of dodecyl triphenyl phosphonium bromide (DTP), and a DTP-PGS hybrid is prepared. Antibacterial performance of this novel hybrid is investigated for both Gram-positive and Gram-negative bacteria. The results show that the DTP could be absorbed on the surface of PGS whi...

Desktop publishing (DTP) is a comparatively recent concept which captured the imagination of a large number of microcomputer users. For a time, the enthusiasm for DTP could be described as being over-optimistic, or even worse. Fortunately, this phase in the development of systems for DTP has passed and a more realistic approach is now being taken. DTP, with the appropriate hardware and software...

In organic solvents, 1,3-dimethyl-4-(2,4-dichlorobenzoyl)-5-hydroxypyrazole (DTP) converted chlorophyll a and b extracted from rice seedlings (Oryza sativa L. ;Kinmaze') into pheophytin a and b, respectively. On comparing the chlorophyll-converting activity of DTP to those of acetic, glycolic, 2,4-dichlorobenzoic, monochloroacetic, 2,6-dichlorobenzoic, pyruvic, and dichloroacetic acids, it was ...

BACKGROUND and objective Previous studies from areas with high mortality in West Africa have not found diphtheria-tetanus-pertussis (DTP) vaccine to be associated with the expected reduction in mortality, a few studies suggesting increased mortality. We therefore examined mortality when DTP was first introduced in rural areas of Guinea-Bissau in 1984-1987. Setting Twenty villages in four region...

Distance to Transition Point (DTP) has shown good performance in term selection for Text Categorization task. Previous experiment report that DTP behaves well as DF and CHI term selection techniques. In this paper we present the results of using DTP computed in a global and local fashion; considering the whole of categories of training set. The results confirm that performance of DTP globally c...

Target Propagation (TP) is a biologically more plausible algorithm than the error backpropagation (BP) to train deep networks, and improving practicality of TP an open issue. methods require feedforward feedback networks form layer-wise autoencoders for propagating target values generated at output layer. However, this causes certain drawbacks; e.g., careful hyperparameter tuning required synch...

Dynamic ticket pricing (DTP), a new revenue management (RM) strategy in sport, has grown in popularity in response to the demand-based ticket resale market. Previous research has examined the relationship between the primary and secondary ticket market and determinants of price in a DTP environment. However, research has not focused on consumer perceptions of DTP or resale prices. The purpose o...

The Disjunctive Temporal Problem (DTP) involves conjunction of DTP constraints, each DTP constraint being a disjunction of difference constraints of the form x − y ≤ c, where x and y range over a domain of interpretation, and c is a numeric constant. The DTP is recognized to be an expressive framework for constraints modeling and processing. The addition of preferences, in the form of weights a...
