In the last ten years industrial society has been confronted with chemical accidents in various industries. The chemical accidents are broadly defined as uncontrolled release of significant amounts of toxic, explosive or flammable into the environment during the production, storage, operation, transportation and disposal of effluents. Usually result from internal factors such as failure of materials / equipment, operational failures or human errors, while external factors are attributed to natural disasters or acts of vandalism, terrorism, sabotage, etc. This paper aims to demonstrate the importance of the formation of critical consciousness technique in demand and the goal of formulating clean technologies that do not come against the interests of society, mainly focused on reducing industrial accidents, life cycle, environmental preservation and the reduction of power consumption.

Opportunity offered by the Empowerment ICT: A Survey ICT and Empowerment in the Espigadilla
CIDITIC, Technological University of Panama, Panama
ICT could redesign the health service environment in a more representative way. Replacing structures and models centered in the patient, achieving objectives y immediate goals of active participation through the empowerment of ICT health services. I safe to promote the use of ICT in a context of health in central America could give rise to grave social, ethical and practical problems, especially in relation with the digital gap, meaning the participations of persons without access to technology. Never the less this article plants an empowerment model centered in the patient, supported by ICT, which will demonstrate the reach that can be achieved through the empowerment of ICT in the context of health. On the other hand, a first approach to the model will be presented, through a field study conducted in a rural area of Panama with which the reach of the model is to be measured.

Security is always been an issue due to increasing crime rates most especially in the developing countries. Therefore, technology is being used as a tool to provide greater safety as preventive action to lessen the probability of car theft but due to unavoidable circumstances, corrective action is still an alternative plan. This design project dealt with a system that used to alert the car owner if there is someone who illegally opened the door in the driver’s seat and trying to steal the car. A text message will be received by the car owner from the microcontroller unit with SMS module installed inside the car connected from the car door. Once the message was opened, there is an option for the owner to open the Internet Protocol camera to view the image inside the car. There is also a capability for the car owner to determine the location of the car through the use of Global Positioning System.

Faculty of Science ben ms'ikUniversity, Mohammadia Casablanca, Morocco
The domain of mobile networks ad-hoc (MANET) has won an important part of the interest of researchers and become very popular in recent years. MANET can operate without a fixed infrastructure and can survive rapid changes in the network topology. They can be formally considered as graphs in which all edges varies over time. The main method for assessing the performance of MANET is the simulation. This article is subject to routing protocols on demand with identical loads and environmental conditions and to assess their performance relative to the six performance criteria are following: rate, flow Numhops, energy, end-to-end delay and the collision rate.

In this paper, we have classified second order linear PDEs into three types, hyperbolic, parabolic and elliptic. Hyperbolic equations have two distinct families of (real) characteristic curves, parabolic equations have a single family of characteristic curves, and the elliptic equations have none. All the three types of equations can be reduced to canonical forms. Hyperbolic equations reduce to a form coinciding with the wave equation in the leading terms, the parabolic equations reduce to a form modeled by the heat equation, and the Laplace’s equation models the canonical form of elliptic equations. Thus, the wave, heat and Laplace’s equations serve as canonical models for all second order constant coefficient PDEs.

Some Aspects of Derivation in Ternary Semirings
Zulfi College of Sciences, Majmaah University, K.S.A
In this paper we are concerned with the study of some properties of ideals in ternary semirings. The notion of idempotent, invertible and strong invertible elements has been introduced. We also give another notion of commutativity and introduce the notion of cyclic commutativity. We construct some prime ideals in connection with the inverse element.
The second part of the paper is devoted to the study of derivations on particular elements of such algebraic structures. We also give some examples of co-ideals.

A Novel Robust Method to Add Watermarks to Bitmap Images by Fading Technique
Firas A. Jassim
Faculty of Administrative Sciences, Management Information Systems Department, Irbid National University, Irbid-2600, Jordan
Digital water marking is one of the essential fields in image security and copyright protection. The proposed technique in this paper was based on the principle of protecting images by hide an invisible watermark in the image. The technique starts with merging the cover image and the watermark image with suitable ratios, i.e., 99% from the cover image will be merged with 1% from the watermark image. Technically, the fading process is irreversible but with the proposed technique, the probability to reconstruct the original watermark image is great. There is no perceptible difference between the original and watermarked image by human eye. The experimental results show that the proposed technique proven its ability to hide images that have the same size of the cover image. Three performance measures were implemented to support the proposed techniques which are MSE, PSNR, and SSIM. Fortunately, all the three measures have excellent values.

Pakistan Railways routed almost all the major cities of Pakistan. British government gives us the world’s best railway infrastructure. Just few decades’ back people considered the Pakistan railways as the safest and the economical mode of transport. Due to the provision of good facilities and following the schedules people liked to travel via Pakistan Railways to reach to their destination. Further more different companies and government institutes relay on Pakistan railways for the transportation of their goods safely and well on time. But unfortunately our corrupt railway management leads this department towards the collusion....

Condition monitoring is the process used to analyze the operating condition of rotating machines. Vibration analysis is the most commonly used technique. In this paper vibration analysis is used to analyze the operating condition of Centrifugal Blower under various misalignment conditions. The experiments were carried out for various parallel misalignment and angular misalignment conditions between blower shaft and motor shaft. Different levels of misalignments conditions were introduced to study the effect on rotating machinery. Vibration signatures were acquired for normal and faulty conditions at different cut-off speeds of 1250 rpm, 1450 rpm and 1650 rpm in horizontal, in vertical and in axial direction. The acquired vibration signatures were presented and analyzed for these fault conditions. It was observed in the vibration spectrum that the vibration amplitude component at 2X is predominant in both the cases also it was observed that the slight increase in 1X and 3X vibration amplitude component at higher speed with higher level of misalignment. Also the comparison of 1X, 2X and 3X vibration amplitude components for all the three measurement direction for both type of misalignment were made.

The national geodetic network stations of Sudan were observed and computed using conventional triangulation techniques that related to the local datum (Adindan) and reduced by the parameters of Clarke 1880 ellipsoid. Nowadays that conventional technique has been replaced by satellite system/Global Positioning System (GPS) in which observations are reduced to the geocentric datum WGS84 reduced toWGS84 ellipsoid. Today, each survey project in the country has its own independent absolute base station that is not relatively connected to the other projects. This independent observation makes arise of problem of inconsistency between the coordinates of different projects in Sudan. Through this study work, the definition of the datum orientations and the transformation parameters between Adindan local datum and geocentric WGS84 datum were determined twice; Firstly, using the absolute GPS base stations that distributed over the country common to the national stations. Secondly, using the International Terrestrial Reference Frame 1996 (ITRF96). Results showed that the GPS coordinates relative to ITRF stations seem to be more consistent to the local datum than those of absolute GPS base stations. This result indicates that the ITRF observation is suitable for national network establishment than absolute GPS observations.

The Organic Acid Anhydrides (OAAs) are highly allergenic compounds used in many local industries of SITE Area Kotri, Sindh,Pakistan including: Textiles, Dyes, Plastics, Resins, Pharmaceuticals, Paper, Paints, Pesticides and Adhesives etc. The hazardous OAAs also called Haptens conjugate with proteins forming protein adducts (Complex) in exposed workers leading to harmful diseases like Conjunctivitis, Rhinitis, Asthma and even Cancer after long term exposure. Method:
This whole study is made to investigate the role of Serum proteins separated by Sodium Dodecyl Sulphate (SDS-PAGE) Electrophoresis on 10-15% gel and then stained with Coomassie Brilliant Blue (CBB-R 250) to detect proteins, which could serve as marker for the early detection of disease in exposed workers from local Dye factory SITE Area Kotri.
The serum proteins resolved into clear sharp bands from 10kDa-200kDa in each group studied. The dominant band of 66kDa was prominent among many workers also showing weak bands at 14,21,45,98 & 135 KDa. However there were very weak and diffused bands seen at 66kDa in many normal cases along with 27,40,53,61,74,92 and 130kDa bands observed.
A dark band of 66kDa among exposed workers to OAAs indicate the folding of protein that shows abnormality and transformation of functions by forming an adduct leads to allergenic problems & symptoms.
