With the industrialization in the 19th century the desire for energy rose continuously resulting in a high
emission of CO2 which is one of the greenhouse gases. Storage of CO2 in the underground, e.g., depleted oil and gas
reservoir, is proved to be one means of mitigating greenhouse effect and meanwhile enhancing oil and gas recovery. In
order to ensure an effective long-term containment of CO2 in the underground, the well integrity has to be evaluated
prior to the commencement of implementation. The evaluation of well integrity for plugged and abandoned well is a big
challenge, because conventional methods to assess well integrity, e.g., logging, coring, cannot be applied on abandoned
wells. Many researchers have proposed generic methods to assess well integrity. This paper is going to provide a review
over these methods and put forward a structure of a new comprehensive methodology which can bring a step forward for
well integrity evaluation.

Today, with advance in technology and industry, using variety of devices which work by electricity is very
widespread and conventional. In electrical devices electromagnetic fields are created, then electromagnetic waves are
seen around human more than ever before. These fields are strong or weak depending on the type of electric devices.
Though now, household electrical appliances are standardized from production of electro-magnetic fields But how is the
effect of waves of weak fields on cells and materials inside of living organisms body? The purpose of this research is
studying the effect of electromagnetic waves energy on one of types of phospholipids that are exist in living organism
bodies.

In this study, the effect of different storage methods on the proximate composition and functional properties of
sweet potato (Ipomoea batatas Lam.) was investigated. The sweet potato tubers were harvested from a local farm in
Jukwa, a village within the vicinity of Cape Coast. For the proximate composition, sample from the fresh tubers were
thoroughly sorted, washed, peeled and subjected to analysis for moisture, ash, protein, fat, fibre, carbohydrate and
reducing sugars. For the functional properties the peeled samples were sliced, sun-dried, milled into flour and subjected
to analysis for water absorption, oil absorption, foaming capacity and swelling power. The rest of the tubers were cured
and stored in sawdust, wood ash and ambient conditions for six weeks in a storage facility. Samples were taken from
various storages every two weeks, processed and subjected to proximate composition and functional properties analysis.
Results of the proximate analysis carried on the fresh sweet potato samples showed 59±0.69 % moisture, 2.27±0.17 %
ash, 7.85±0.08 % protein, 0.95±0.00 % fat, 0.21±0.00 % fibre, 62.6

The high quality air without particle must be provided in operating rooms that are known as clean room.
Particles cause the risk of infection in clean rooms. But, the infection risk ratio decreases by using a clean-air system. For
a perfect clean room, the clean-air system must be controlled by measuring particles and must be classified in according
to the international standard. The related standard is, ISO 14644-1:1999(E) Cleanrooms and associated controlled
environments Part 1: Classification of air cleanliness. In according to the standard, the clean room is classified from ISO
Class 9 to Class 1 by measuring of particles (0,1µm, 0,2µm, 0,3µm, 0,5µm, 1µm, 5µm). The clean room classification
requires a scientific study. But, sometimes, the particle measurement, unfortunately, is performed by non-licensed
personnel by only controlling of hepa filters instead of standard methods. In this case, the clean room can not be
classified. The objective of this study,

Internet provides drastic access to the news articles from different information sources around the world. The
main approach is used to find out the users preference from both news content and user information. Incremental
clustering is done on the web news document in order to group the documents for recommendation. The idea of
conceptual clustering is used. It finds the similarity between them which is called as correlation measures. Here the data
is collected from data set through various web sites of news group

An adsorbent prepared from Ipomoea carnea Leaves (AAIC), by acid treatment was tested for its efficiency in
removing nickel ion. The process parameters studied include agitation time, initial Nickel ion concentration, adsorbent
dose, pH and temperature. The adsorption followed second order reaction equation and the rate is mainly controlled by
intra-particle diffusion. Freundlich and Langmuir isotherm models were applied to the equilibrium data. The adsorption
capacity (Qm) obtained from the Langmuir isotherm plot at an initial pH of 6.5 and at 30, 40, 50, 60 ± 0.5 0C. The
influence of pH on nickel ion removal was significant and the adsorption was increased with increase in temperature. A
portion of the nickel ion was recovered from the spent AAIC using 0.1M HCl.

Full adder is a basic building block of many application specific integrated circuits. The paper evaluates and
compares the performance of various full adder circuits which are designed using techniques such as XOR,
transmission gates, multiplexers etc. Also a full adder circuit designed using multiplexer is proposed. The performance
of these circuits is based on 180nm process model at supply voltage of 2.5V. The TSPICE simulation results show that
the proposed circuit’s performance is better as compare to the circuits that are found in literature whose performance is
evaluated.

Huge data mining techniques have been used for mining useful pattern in text document. Text mining can be
used to extract the data in document. It is effectively use and update the discovered pattern; still the research is not yet
completed. The existing approach is term based approach; they suffer the problem of polysemy and synonymy. In the
past years, people have used pattern based approaches for hypothesis which perform better than the term based ones, but
many of the experiments do not support this hypothesis. In this paper present a new idea about the effective pattern
discovery technique which involved the processes of pattern deploying and pattern evolving, to improve the effectiveness
of using and updating discovered patterns for finding relevant and useful information

Routing protocols for sensor networks are often designed with explicit assumptions, serving to simplify design
and reduce the necessary energy, processing and communications requirements. IPv6 Routing Protocol for Low Power
and Lossy Networks (RPL) is a routing protocol specifically designed for Low power and Lossy Networks (LLN)
compliant with the 6LoWPAN protocol. It currently shows up as an RFC proposed by the IETF ROLL working group.
However, RPL has gained a lot of maturity and is attracting increasing interest in the research community. As a point of
comparison, a different protocol, called LOAD, is also studied. LOAD is derived from AODV and supports more general
kinds of traffic flows

Digital Image Watermarking provides copyright protection to digital images by hiding important information
in original image to declare ownership. Perceptual transparency and robustness, capacity and blind watermarking are
main features those determine quality of watermarking scheme. An effective image coding technique which involves
transforming the image into another domain with Ridgelet function and then quantizing the coefficients with modified
TRUST has been presented in this paper. Ridge functions are effective in representing functions that have discontinuities
along straight lines. Normal Wavelet transforms fail to represent such functions effectively. TRUST has been defined for
normal wavelet decomposed images as an embedded quantization process. If the coefficients obtained from Ridgelet
transform of the image with more discontinuities along straight lines have to subject to quantization process with
TRUST, the existing structure of the TRUST should be modified to suit with the output of the Finite Ridgelet Transform
(FRIT). In this paper, a modified SPIHT algorithm for FRIT coefficients has been proposed. The results obtained from
the combination of FRIT with modified TRUST found much better than that obtained from the combination of Wavelet
Transform with TRUST
