the paper determined optimum farm plan for food security among smallholder farmers in imo state, nigeria. data were collected with structured and validated questionnaire from 180 smallholder crops farmers in imo state. data were analyzed using descriptive statistics (mean, frequency distribution and percentages), budgetary analysis and linear programming model. results show that the mean age of...

Emissions from vessels are a major environmental concern because of their impacts on the deterioration environment, especially global warming atmosphere. Therefore, International Maritime Organization (IMO) concerns significant care to protection through reduction exhaust emission and improvement energy efficiency technical operational measures. Among suggested measures IMO, alternative fuel su...

Electron multiplying charge coupled devices (EMCCDs) have revolutionized the world of low light imaging by introducing on-chip multiplication gain based on the impact ionization effect in the silicon. They combine the sub-electron readout noise with high frame rates. Signal-to-noise Ratio (SNR) is an important performance parameter for low-light-level imaging systems. This work investigates the...

Nowadays, most merchant vessels use Heavy Fuel Oils (HFOs) for the ship propulsion. These fuels are cost effective but they produce significant amounts of noxious emissions. To comply with IMO & MARPOL environmental regulations, Liquefied Natural Gas (LNG) is becoming an interesting option for the merchant ships. The purpose and scope of this paper is to describe the fact...

While it is generally accepted that the overall level of maritime safety has improved in recent years, further improvements are still desirable. It is fair to say that much of maritime safety policy worldwide has been developed in the aftermath of serious accidents (such as ‘Exxon Valdez’, ‘Estonia’, ‘Erika’ and ‘Prestige’). Industry circles have questioned the wisdom of such an approach. The s...

this study was designed to investigate the demand for institutional credit among small scale farmers in imo state. a sample of 40 livestock and 50 food crop farmers were selected respectively using multistage random sampling technique. data were collected with a well structured questionnaire administered to a total of 90 randomly selected farmers. data collected were analyzed using descriptive ...

I'm sitting at a table in a Frankfurt airport waiting room, playing bridge with three high school students. Slung about my waist is a fanny pack stu ed with passports and plane tickets for eight. A cacophony of Greek buzzes about us, as tired travellers wait to board the plane to Athens. Among them is our contingent, easily distinguishedby our bright red golf shirts emblazoned with red maple le...

Bill Sands has conjectured that for no integer n ≥ 3 does there exist a vector of n integers whose dot products with all permutations of (1, . . . , n) form a complete residue system mod n!. In this paper we verify this conjecture when n + 1 is not prime, n = 4, and n = 6. We also suggest a generalization of the problem.
