the present study was aimed at evaluating the possible use of inter polymer complexed (ipc) films of xanthan gum (xg) and cationic guar gum (cgg) for formulating domperidone bioadhesive films. formation of bonds between –coo¯ groups of xg and –n + (ch 3 ) 3 groups of cgg was evident in the ftir spectra of ipc films. bioadhesive strength of the films was evaluated employing texture analyser. wat...

       Food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. Plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. Presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they ...

background: ebt and ebt3 radiochromic films have been used in radiotherapy dosimetry for years. objective: the aim of the current study is to compare ebt and ebt3 radiochromic films in dosimetry of radiotherapy fields for treatment of parotid cancer. methods: calibrations of ebt and ebt3 films were performed with identical setups using a 6 mv photon beam of a siemens primus linac. skin dose was...

We consider the problem of distributed deterministic broadcasting in radio networks. Nodes send messages in synchronous time-slots. Each node v has a given transmission range. All nodes located within this range can receive messages from v. However, a node situated in the range of two or more nodes that send messages simultaneously, cannot receive these messages and hears only noise. Each node ...

Illegal labour immigration is increasingly a source of concern to politicians and the public in relatively rich countries within the Southern African Development Corporation (SADC). This paper examines the status of illegal immigration in Botswana and South Africa. The definition of illegal immigration is discussed. It draws extensively from similar experiences in the United States of America a...

Broadcasting protocols can lower the cost of video-ondemand services by more efficiently distributing all videos that are simultaneously watched by many viewers. The most efficient broadcasting protocols require a customer settop box capable of capturing data from five to seven video channels at the same time. We show how to modify existing broadcasting protocols so that their client bandwidth ...
