Microbiological quality and safety of cooking butter in Beni-Suef governorate-Egypt
AMS Meshref
African Health Sciences , 2010,
Abstract: Background: Cooking butter is one of the most popular types of fat consumed in Egyptian houses. It is produced in villages by rural women that are usually using their traditional knowledge during manufacturing. Objective: To study the rate of contamination and hygienic quality of cooking butter Methods: A total of 60 random samples of cooking butter, were collected from different farmers' houses in different villages, Beni-Suef Governorate, Egypt. Cooking butter samples were examined for psychrotrophic bacteria, total coliforms, faecal coliforms and molds and yeasts counts. Additionally examination for the presence of pathogenic bacteria like E.coli, S.aureus and Ps.aeruginosa were also performed. Results: The microbiological examination revealed that 100, 100, 36.7, 31.7, 31.7 and 23.3 % of the examined samples were contaminated by psychrotrophic bacteria, molds and yeasts, coliforms, faecal coliforms, E.coli and S.aureus, respectively. None of the examined cooking butter samples contained Ps.aeruginosa. The means values of sodium chloride and titratable acidity were 0.57 ± 0.05 % and 0.20 ± 0.013%, respectively. Conclusion: The present study showed that cooking butter is produced under unhygienic condition and without good manufacturing practice. The Public health significance and suggestive control measures are discussed.
Distribution and abundance of the edible orchids of the southern highlands of Tanzania
AMS Nyomora
Tanzania Journal of Science , 2005,
Abstract: All orchids have showy flowers and many are therefore popular as exotic houseplants as well as contributing significantly to eco-tourism. A special attribute of some orchid genera is the production of edible tubers, an attribute that can contradict eco-tourism if harvesting is not done sustainably. Such is the case in the Southern Highlands where for example, Kitulo Plateau has been gazetted to be a National Park but where edible orchid harvesting is a serious conservation problem. Botanically, unsustainable harvesting can mean the loss of important germplasm even before some species are known to exist. A field survey was undertaken for three weeks in March 2002 in the Southern Regions of Tanzania (Iringa, Mbeya, Rukwa and Ruvuma) to study aspects of the extent of the distribution, diversity and density of edible orchids. Tools for identification included structured questionnaire, on-the-spot identification as well as using herbarium voucher samples and keys. Analytical tools included Shannons' diversity index and Canonical Community Ordination (CANOCO) and ANOVA in Microsoft Excel. A total of 13 edible species of orchids were documented during the survey all of them from the genera Habenaria, Disa and Satyrium. While Tandala and Molo hills had the highest species Diversity Index (over 1.2), Kitulo Plateau showed the greatest species density of over 200/30m2 quadrants. Local communities in Madaba in Ruvuma, Molo, and Mbisi in Rukwa regions used the orchids as vegetables and snacks in lieu of animal meat. The rest of the studied areas used orchids as a source of cash by selling to Zambian traders and or to their middlemen. More research is needed to monitor growth phases, reproductive/propagation studies as well as taxonomic and systematic studies preferably using molecular techniques to determine relationships amongst edible orchids and their non edible relatives.

Health Consequences of Nuclear Fission Products
AMS Ajlouni
Journal of Applied Sciences and Environmental Management , 2007,
Abstract: Radionuclides produced in fission process moves from its source, to human food chain to become available for human consumption determines their effects on his health. According to models used to predict health effects of these radionuclides enter the human body, a large number of fatalities, malignancies, thyroid cancer, born (genic) defects, etc. Nevertheless, the actual data after Chernobyl and TMI accidents, and nuclear detonations, were not consistent with these models. Deep Atomic Binding Hypothesis (DAB)), interprets the actual field data.
Search for antihelium in cosmic rays
AMS Collaboration
Physics , 2000, DOI: 10.1016/S0370-2693(99)00874-6
Abstract: The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 in a 51.7 degree orbit at altitudes between 320 and 390 km. A total of 2.86 * 10^6 helium nuclei were observed in the rigidity range 1 to 140 GV. No antihelium nuclei were detected at any rigidity. An upper limit on the flux ratio of antihelium to helium of < 1.1 * 10^-6 is obtained.
Protons in near earth orbit
AMS Collaboration
Physics , 2000, DOI: 10.1016/S0370-2693(99)01427-6
Abstract: The proton spectrum in the kinetic energy range 0.1 to 200 GeV was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at an altitude of 380 km. Above the geomagnetic cutoff the observed spectrum is parameterized by a power law. Below the geomagnetic cutoff a substantial second spectrum was observed concentrated at equatorial latitudes with a flux ~ 70 m^-2 sec^-1 sr^-1. Most of these second spectrum protons follow a complicated trajectory and originate from a restricted geographic region.
Generation of heralded single photons beyond 1100 nm by spontaneous four-wave mixing in a side-stressed femtosecond laser-written waveguide

Physics , 2015,
Abstract: We demonstrate a monolithically integrable heralded photon source in a femtosecond laser direct written glass waveguide. The generation of photon pairs with a wide wavelength separation requires a concomitant large birefringence in the normal dispersion regime. Here, by incorporation of side-stress tracks, we produce a waveguide with a birefringence of $1.64\times~10^{-4}$ and propagation loss as low as 0.21 dB/cm near 980~nm. We measure photon pairs with 300~nm wavelength separation at an internal generation rate exceeding $5.05\times10^6$/s. The second order correlations indicate that the generated photon pairs are in a strongly non-classical regime.
