The study was aimed at investigating the microbial quality of ice cream and ice pop sold in Gaborone. From the study, a variety of microorganisms were isolated. The population of bacteria was found to increase from the open ice cream samples while the pre-packed ice cream had a lower population of bacteria. The types of microorganisms were both mesophilic and psychrotrophic. The population of m...

In wireless networks, link strengths are often affected by some topological factors such as propagation path loss, shadowing and inter-cell interference. Thus, different users in the network might experience strengths. this work we consider a K-user asymmetric interference channel, where channel gains of links connected to Receiver k scaled with √{P <sup xmlns:mml="http://www.w3.org/1998/Math/M...

Steganography is the science of hiding a message signal in a host signal, without any perceptual distortion of the host signal. Using steganography, information can be hidden in the carrier items such as images, videos, sounds files, text files, while performing data transmission. In image steganography field, it is a major concern of the researchers how to improve the capacity of hidden data i...

Utilizing derivations for the properties of a symmetric Toeplitz matrix, we obtain analytical expressions performance evaluation wireless communication systems using multiple antennas at transmitter and/or receiver, including those keyhole channels, beamforming, and noncoherent detection. Our are based upon closed form have obtained eigenvalues eigenvectors <italic xmlns:mml="http://www.w3.org/...

CHRISTOPHER J . BISHOP The little Bloch space, 130 , is the space of all holomorphic functions f on the unit disk such that lim1 z 1l (f'(z)j(1 Iz12) = 0. Finite Blaschke products are clearly in 130, but examples of infinite products in 80 are more difficult to obtain (there are now several constructions due to Sarason, Stephenson and the author, among others) . Stephenson has asked whether 130...

Background and objectives: Food poisoning has been always a major concern in health system of every community and cream-filled products are one of the most widespread food poisoning causes in humans. In present study, we examined the preservative effect of the cinnamon oil in cream-filled cakes. Methods: Antimicrobial activity of Cinnamomum verum J. Presl (Cinnamon) bark essential oil was exami...

OBJECTIVE To assess the efficacy of 5% imiquimod cream on undifferentiated vulvar intraepithelial neoplasia (VIN), a disease caused by high-risk human papillomavirus. DESIGN Prospective, uncontrolled study. SETTING University hospital vulvar clinic. Patients Twelve consecutive patients treated with 5% imiquimod cream for undifferentiated VIN between March 1, 1999, and May 31, 2001. INTERV...

Measurements of the back scattering by bluntly-truncated tilted cylindrical shells in water reveal a dependence on the aspect angle which can be interpreted using geometrically described coupling mechanisms [S.F. Morse, P.L. Marston, and G. Kaduchak, J. Acoust. Soc. Am. 103, 785-794 (1998)]. By exciting a shell with a suitable acoustic pulse localized in time, the recorded backscattering respon...
