Increased polyamine concentrations play an important role in the development of cancer at all stages, from initiation through to maintenance of the transformed phenotype. One way cancer cells accumulate increased concentrations of polyamines is by increased uptake of preformed polyamines via their PTS(polyamine transport system). The PTS is promisc

This paper presents a detailed review of remote user authentication schemes with smart cards based on bilinear pairings. The first scheme regarding this was proposed by Manik et al. in 2006, which had been modified and improved later in several ways. Here, we analyze all the related proposed schemes, point out their weaknesses and flaws, and note d

Problem statement: The present study investigates the ability of the pTok47 supervirulence plasmid form Agrobacterium tumefaciens A281 to enhance genetic transformation in Hevea brasiliensis. Approach: Hevea anther callus was transformed via Agrobacterium-mediated genetic transformation using two strains of Agrobacterium (GV2260 and GV3850) harbori

Cancer pain is one of the most frequently encountered pain syndromes. With the application of the World Health Organization analgesic ladder, adequate analgesia is achieved in 75% to 90% of patients. The remaining patients suffer from intractable pain requiring intrathecal analgesia. The aim of this study was to retrospectively analyse the pain int

With the advancements of networking technologies and miniaturization of electronic devices, wireless sensor networks (WSN) have become an emerging area of research in academic, industrial, and defense sectors. Sensors combined with low power processors and wireless radios, will see widespread adoption in the new future for a variety of applications

BACKGROUND: Journal advertising is one of the main sources of medicines information to doctors. Despite the availability of regulations and controls of drug promotion worldwide, information on medicines provided in journal advertising has been criticized in several studies for being of poor quality. However, no attempt has been made to systematical

An opportunistic feedback protocol is proposed for orthogonal frequency division multiple access (OFDMA) systems with mixed realtime (RT) and non-realtime (NRT) traffic. This protocol allocates a dedicated feedback channel for each RT user, while it allows all NRT users to compete to send feedback via a contention-based random access feedback chann

The paper aims to highlight the need to incorporate certain Arabic words in the teaching of English to Muslim students. Based on al-Faruqi’s framework on Islamic English for Islamic vocabulary to be retained in their Arabic form in an effort to maintain the original meanings, a set of questionnaires was distributed to teachers who were teaching E

This study attempts to investigate two constructs that are important in everyday lives. The constructs are "happiness" and "religiosity". Since the study of such constructs have been numerous in western literature and the idea of "positive psychology" is being embraced in most current educational field, the researcher felt c

A Crowd Stress Index for use in risk assessment was developed in four parts: a literature review to identify relevant factors and understand the terms 'crowd' and 'crowding'; a study on an underground train; personal interviews; and a climatic chamber experiment in which physiological and subjective measures were taken from people i
