A system of production planning with a built-in capability to monitor performance at all levels of the shipbuilding process is the focus of this paper. The heart of this system—the standardized task block—incorporates individual and comprehensive work packages from fabrication through project completion. The logic, procedure, and economy of the method are discussed with particular emphasis on the modular/zone concept of ship construction, which provides the basis for establishing the task block matrices.

Abstract This pre-registered event-related potential study explored how vocal emotions shape visual perception as a function of attention and listener sex. Visual task displays occurred in silence or with a neutral or an angry voice. Voices were task-irrelevant in a single-task block, but had to be categorized by speaker sex in a dual-task block. In the single task, angry voices increased the occipital N2 component relative to neutral voices in women, but not men. In the dual task, angry voices relative to neutral voices increased occipital N1 and N2 components, as well as accuracy, in women and marginally decreased accuracy in men. Thus, in women, vocal anger produced a strong, multifaceted visual enhancement comprising attention-dependent and attention-independent processes, whereas in men, it produced a small, behavior-focused visual processing impairment that was strictly attention-dependent. In sum, these data indicate that attention and listener sex critically modulate whether and how vocal emotions shape visual perception.

An experiment was conducted at Idaho National Laboratory to investigate the bypass flow associated with a Gas Turbine-Modular Helium Reactor in direct support of Computational Fluid Dynamic validation [1]. Velocity fields within a representative quartz model, consisting of an upper plenum, upper block, and lower block, were measured using Particle Image Velocimetry; after which, flow rates were calculated in each section. The present study was carried out to determine flow distribution from the upper plenum to the fuel block assembly. It was found that the flow rates in the lower six coolant channels varied from their average only by 2.4, 4.6, and 2.5% for the low, medium, and high flow cases, respectively. Consequently, it was concluded that the non-uniform inlet velocity condition in the upper plenum had insignificant effect on flow distribution to the coolant channels and interstitial gap.

Due to the slow growth and long gestation period of oil palm farmers are often faced with challenges of weed control before oil palm canopy closure hence the need to introduce plantain as component crop with the oil palm. A two years trial was conducted in in Ovia North East LGA, Edo State, Nigeria (Latitude 6.636oN, 6.909oN and Longitude 6.182oE, 6.364oE) to evaluate the effect of NPKMg fertilizer and interplanted cassava on growth and yield of plantain in oil palm based system. The treatment consisted of NPKMg fertilizer as the main block treatment (with and without NPKMg fertilizer) and crop combinations [oil palm/plantain (OPP) and oil palm/plantain/cassava (OPPC)] as sub block treatments. The treatments were laid out in split block arrangement in RCBD replicated thrice. Data were collected on plantain plant height, number of leaves/pseudostem, leaf area index, number of suckers/pseudostem, number of days to 50% flowering of main psuedostem and first ratoon plants, number of days to first appearance of peeper sucker from main pseudostem, number of leaves at flowering from main pseudostem and first ratoon plants, finger weight (kg/bunch), finger circumference/finger (cm), finger length/finger (cm), number of fingers/bunch, biomass weight (t/ha), number of bunches/ha and bunch yield (t/ha). NPKMg fertilizer significantly increased (p<0.05) the growth and number of sucker produced. Plantain planted in OPP combination had taller plant and more number of suckers (first ratoon plant and second ratoon plant, respectively) relative to those in OPPC combination while plantain planted in OPPC combination lead to delayed appearance of peeper suckers, delayed fruiting of plantain and resulted to 18, 15.8, 1.6, 6, 8.3 and 12 % increase (p<0.05) in plantain bunch weight, finger weight, finger circumference, finger length, number of fingers and biomass weight, respectively relative to those in oil palm/plantain (OPP) combination.
