Complementary food blends and malnutrition among infants in Ghana: A review and a proposed solution
Widespread malnutrition among Ghanaian infants could be attributed to unfortified plant-based complementary foods commonly used at the household level. This review summarises the publications on the development of complementary food blends and intervention trials aimed at improving the nutritional status of Ghanaian infants. The complementary food blends are cereal-based which are developed from maize (in higher...

Comparative phytochemical and ethnomedicinal survey of selected medicinal plants in Nigeria
Phytochemical screening and ethnomedicinal survey of twenty-two medicinal plants distributed in fifteen different families were carried out in order to know the distribution of secondary metabolites and the diseases being treated with these plants. It was discovered that alkaloids, tannins and saponin were present in all. Flavonoid was absent only in Peperomia pellucida; five out of these plants lack terpene,...

The Tucumán solar UV transparency experiment: Preliminary results and prospective
Two radiometers were simultaneously operated during the past dry season in Tucumán province, NW Argentina. The main objective was to determine particulate matter content of the atmosphere. Ampimpa, an astronomic observatory up in the mountains, was adopted as the reference, non polluted monitoring site. The INTA meteorological facility at Famaillá, in the plains, was chosen as an air pollution test site,...

An electromagnetism-like mechanism for solving cell formation problems
This paper presents an electromagnetism-like mechanism (EM) algorithm in order to solve cell formation problems. Based on the attraction-repulsion principle in electromagnetic theory, each combination of the part and machine groups was regarded as a charged particle. The total force calculation and the move along the total force calculation were then determined out to either maximize the cell group effectiveness or...

Household Asset Index and Total Iron Intake, but not Education, best Predict Iron Status in a Black Population Sample in Gauteng, South Africa
This paper reports on independent associations of household asset index and education, as components of socio-economic status, on iron status in a black population sample in Gauteng province. The study was cross-sectional, involving 40 men, 184 women (n = 224), randomly selected, based on informed consent. Socio-economic, dietary intake and biochemical data were collected using household socio-demographic...

Quantum message exchanging network using entanglement swapping and decoy photons
We propose a scheme for secure quantum message exchanging network following the idea in entanglement swapping. In this scheme, the servers of the network provide the service for preparing the Greenberger-Horne-Zeilinger (GHZ) entangled states as quantum channels. For preventing the eavesdropping, a security checking method is suggested. After the security check, anyone of the authorized users can exchange his/her...

Multi-user detection in ultra-wideband multiple-access communications systems using an efficient heuristic algorithm
This paper investigates learning and achievable bit error rate (BER) performance of ultra-wideband (UWB) systems that use intelligent multiuser detector (MUD) when communicating over UWB channels that experience both multiuser interference (MUI) and intersymbol interference (ISI), in addition to multipath fading. Multiple access interference (MAI) degrades performance of conventional single user detector in UWB systems....

Natural radioactivity in drinking and mineral water in Johor Bahru (Malaysia)
The radiological quality of 238U, 232Th and 40K in some samples of drinking and mineral water collected in Johor Bahru, Malaysia has been measured by direct ï§ ray spectroscopy using high purity germanium detector in this paper. Mean activity concentration of 238U, 232Th and 40K in drinking and mineral water were found 1.48 ± 0.12, 9.59 ± 0.83, 39.67 ± 1.69 ppm and...

Skeletal ontogeny of Seychelles giant tortoises (Aldabrachelys/Dipsochelys)
The skeletal development of captive bred Seychelles-Aldabra giant tortoises (Dipsochelys/Aldabrachelys) was studied from late embryos to adults based on 93 specimens (45 embyronic). The pattern of ossification is described and the developments of the characters used to distinguish different morphotypes are investigated. The timing of ossification of different bones in this genus is similar to the patterns reported for...

Evaluation of microbiological hazards in barbershops in a university setting
There is a growing concern that barbershops could serve as a potential source of bacterial, fungal or even viral infections and little is known about microbiological hazards of barbershops in the university environment in Nigeria. This study evaluated microbiological hazards of barbershops in a university setting in Nigeria. To determine the types of microorganisms prevalent in barbershops, combs, brush, clippers and...
