Spectrophotometric estimation of nitro tyrosine by azo-coupling reaction
3-Nitrotyrosine has been identified using techniques like immunohistochemistry, HPLC, GCMS to demonstrate as a relevant biomarker in various disorders such as neurological, cardiovascular and others. Estimation of 3-NT by spectrophotometric method has been performed to measure 3-NT over decades. However none of the above methods have been translated to diagnose the diseases, but pathological conditions. Therefore here is an attempt to develop a method to be employed as a diagnostic tool. Current work is focussed on including preparation of 3-NT and further to derivatives using Ă²-Napthol to yield diazotised product. All these intermediates of diazotized products have been characterized by ESI MS and the final colored dye was measured spectrophotometrically which exhibits ĂÂť max at 551 nm. The dye has been measured and compared with the direct measurement of 3-NT. The sensitivity of measurement of 3-NT increases by 10 fold, by and large we can estimate 20 ĂÂźM concentration of 3-NT
A Context Gathering Framework for Context-Aware Mobile Solutions
One of the fundamental design issues in context-aware mobile
services development is the necessary support for adequately
powerful yet efficient querying of the sensory data. This issue
argues for research into the creation of a technology-independent,
high-level software application programming interface (API) that
provides mechanisms for dealing with the heterogeneity of
sensors providing raw context data. In this paper, we review
approaches in existing context-aware platforms especially those
that consider with sensory data acquisition. The review formed
the basis for the design and development of the context gathering
framework which consists of sensor data model, messaging and
communication protocol and software application programming
interface. These components form as one of the enabler to support
the development of context aware mobile applications
MEDICT: A Malay<-> English Bilingual Dictionary For Java Mobile Phones
Today, mobile phones provide number of advanced functions, among which possibility of running mobile applications
seems to be the most interesting feature. It changes a standard mobile phone into a mini-size yet still powerful computer
that able to run various applications, for example games, stock checkup, map guide, dictionary and so on. This paper
presents a project currently in progress which aims at the construction of bi-directional Malay - English translation
dictionary named MEDict. MEDict is an easy-to-use mobile dictionary that is the ideal reference tool for all those
requiring quick access to word translations. MEDict will ideally suit J2ME mobile phones with GPRS connectivity. This
paper delivers the initial development progress of MEDict. It covers the functional requirements and possible
development approaches followed in building MEDict. The project incorporates the development of four main
components: (1) a java-based mobile client that provides interface for front-end query input; (2) a back-end database for
serving dictionary contents; (3) a dictionary service for handling the exchange between the mobile client's queries and the
database; (4) a web system that allows the administrator to manage the dictionary contents. The key contribution of this
study is the use of Java and mobile technologies to develop a translation dictionary between two languages that has not
been previously supported. The developed mobile dictionary is expected to meet the needs of a wide range of users such
as language learners, native speakers, travelers and business professionals in Malaysia
Development of a Multimedia Courseware as a Teaching Aid for Children with Dyslexia
Dyslexia is a language based learning disability resulting in people experiencing
difficulties in reading, spelling, writing and speaking. These problems are sometimes
compounded by short term memory difficulties, a lack of organisational skills and
time management issues which all have an impact on learning. This paper focuses on
the planning, analysis and design of an e-learning courseware to teach dyslexics to
read using the âpicture thinkingâ model. The development of this e-learning
courseware involves transforming the traditional content of printed books from
passive prints and illustrations into interactive multimedia content. The interactive
multimedia content will focus on clear presentation of materials, good navigational
assistance and a variety of multimedia options to tap into visual, auditory and
kinaesthetic skills to support dyslexics. The targeted users will be children with
dyslexia and pre-schoolers aged 5 to 7 learning to read Bahasa Melayu. A successful
implementation of this courseware will be useful to the dyslexic learners as it will use
picture thinking model and multisensory approach to the best of their ability instead of
approaching them with the same teaching approaches used to teach their non- dyslexic
counterparts
Building of the Enabled Web-Based GIS Participation System: A Tool to Enhance Community Participation in City Development Plan
This research has been conducted under the
frame work of GIS interoperability infrastructure
financed by the Malaysian Ministry of Science and
Technology. In this paper, we discuss the
development and analyze the potential application
of the Geographical Information System (GIS) and
Internet computing to enhance community
participation in the decision making processes i.e.
in Local Plan of Block 3, Melaka Tengah district as
a model. The focus of this paper is on the designing
and development of the enabled Web-based GIS
Participation System called, GISPSS. It is
considered to be similar to a Real Time Resources
Discovery Server but it comprises four main
complimentary components: the Map Viewer, the
Objection Support, the Planning Process
Documentation, and the Web Content
Management. The functional features of these
components are highlighted. The multi-tiered
architecture forms the basis of the Enabled Webbased
GIS system has been adopted in this
research
An Assistive Multimedia Courseware for Dyslexics
One of the most promising areas of education is the development of computer-based
teaching materials, especially interactive multimedia programs. Interactive multimedia allows
independent and interactive learning, and yet presents the learning information to the learners in
newly engaging and meaningful ways. This paper delivers the theoretical concepts and design of a
multimedia courseware called âMyLexicâ. âMyLexicâ is the first learning tool to nurture interest on
Malay language basic reading among preschool dyslexic children in Malaysia. The theoretical
framework proposed in the study is based on research in dyslexia theory with Dual Coding Theory,
Structured Multi-sensory Phonic Teaching and Scaffolding instructional technique. Detail
explanations on its learning content are also discussed. The courseware is hoped to contribute a
significant idea to the development of technology in Malay language education for dyslexics in
Malaysia
A deep experimental analysis of energy-proficient firewall policies and security practices for resource limited wireless networks
[EN] The role of firewalls and security principles in resource-limited wireless networks and Wireless Sensor Networks (WSN) is more expected than in any dedicated network environment. The advanced wireless technologies and emerging fashion of autonomous wireless network nodes are mostly expecting resilient firewall services with multi-level security policies. Wireless networks are classified under sensor networks, Internet of Things (IoT) mobile networks, and so forth. According to the expectations, security frameworks are gradually invented around the communication platform using various ideologies. The novel ideology and respective implementation effort open better solutions against wireless network attacks. Anyhow, the minimal production of time complexity, energy complexity, and computation overhead from any novel security approach is always considered under the best practices. The complexity levels directly affect the wireless node's energy consumption ability and operational spans severely. The energy optimization techniques and load-balancing techniques integrated into multi-class firewall rules are extremely useful solutions for resource-limited wireless networks. This article has been motivated to analyze the recent firewall techniques and secure data communication mechanisms used for securing wireless networks. Consequently, the practice of comparative literature analysis helps to improve the current limitations identified under the classified categories of security mechanisms such as energy-optimized security principles and load-balanced security principles. The establishment of secure and energy-optimized multi-class firewall rules in each wireless node assures a healthy focus on next-generation networks. The experiment section shows the benefits of energy-optimized secure network communication in terms of better accuracy and the benefits of load-balanced secure network communication through minimal overhead in computing platforms.Rajasoundaran, S.; Sivakumar, SA.; Devaraju, S.; Pasha, MJ.; Lloret, J.
