Conventional converters make use of surface catalyst process using noble metals like palladium and rhodium. Our concept works based on photo catalytic reactions by Titanium dioxide and Zinc oxide thereby reducing the NOx emissions and CO emissions. Development of this proposal will reduce the fabrication cost of catalytic converter as well as lay seeds of foundation for the future of photocatalytic converters.

The relationship between the process variables (input) viz. flame temperature, preheat air temperature, rotational speed of the furnace, excess air, melting time, and fuel consumption and melting rate (output) is very complex and is agreeable to neuro-fuzzy approach. The neuro-fuzzy model has been created out of training data obtained from the series of experimentation carried out on rotary furnace. The results provided by neuro-fuzzy model compares well with the experimental data. This work has considerable implications in selection and control of process variables in real time and ability to achieve energy and material savings, quality improvement and development of homogeneous properties throughout the casting and is a step towards agile manufacturing.

A total of 68 patients between the ages 0-42 years who presented with sign and symptoms of otitis media at Bichi general hospital were enrolled for this study. Middle ear discharge were collected, processed and bacterial isolates identified using standard microbiological techniques. Disc susceptibility tests were performed on bacterial isolates. Results indicated that there was a high frequency of occurrence of bacteria incriminated in otitis media in the 0-5 and 6-11 year age groups in the two sexes. Male patients in the two age groups were more infected than the female counterparts. The sensitivity pattern obtained in this study show a progressive increase in the emergence of strains that are resistant to many chemotherapeutic agents. Drug resistance among bacterial isolates is a common phenomenon placing challenge to both medical practitioners and genetic scientists. A routine check on sensitivity patterns among these pathogens is vital so as to regulate the prescription measure to be employed.

Specifically, interaction of serum amyloid A fibrils with a cell surface binding site/receptor might alter the local environment to cause cellular dysfunction and to be more favorable for amyloid formation and prevention with alphaB-Crystallin. This is important in relation to the activity of membrane proteins, because losing the activity of such systems will ultimately lead to malfunction or death of the cell. The interactions of Serum Amyloid A (SAA) and Serum Amyloid A protofibrils with hepta 1-6 cells of the mouse are dealt with in detail to study the binding of SAA protofibrils in various onditions. The induced fluorescence, induced circular dichroism, FACScan and MTT assay results have shown the SAA and SAA prototfibrils binding and cell toxicity with the hepta 1-6 cells with different concentrations of alphaB-Crystallin 0.15-15 nM. Specifically, cells were incubated with 1.25-6.25 M SAA-FITC and SAA protofibrils-FITC assayed. The 50% viable hepta 1-6 cells at 4–6 M with an LD50 of 3.5 M. The interaction of serum amyloid A fibrils with a cell surface binding site/receptor might alter the local environment to cause cellular dysfunction and to be more favorable for amyloid formation. In the present study, concluding that the SAA fibrils and SAA protein binding and cell cytotoxicity was reduced in the presence of alphaB-Crystallin.

Moreover, this fault also gives impact to the blackout situation created by a large disturbance as disconnecting back bone lines of the interconnection system. In detail, this case is presented in this paper for evaluating transient stability performances of generating units while producing energy for the load center online the power system operation with the blackout situation designed using a branch tripping method. Furthermore, the transient stability responses are subjected to the power generation of the electric power system in Malang Raya as a real system operation for interacting the generating and demand sites. Results obtained show that voltage changes of Wlingi power station is 0.944 pu to 0.946 pu and its overshoot is 0,962. But the other overshoot of the power generation in Sutami remained to 0.968 pu at 0.5 second after appearing a blackout fault and its voltage increase to 0.952 pu from 0.948 pu at the final stable position.

However, its major disadvantages like poor tensile strength, limited ductility and little resistance to cracking resists its use as a structural material. Hence, in order to overcome these difficulties several new materials have been developed in the recent past.Admixtures are ingredients other than water, aggregates, hydraulic cement and fibers that are added to the concrete batch immediately before or during mixing. Mineral admixtures are usually added to concrete in larger amounts to enhance the workability of fresh concrete, to improve resistance of concrete to thermal cracking, alkali-aggregate expansion and sulphate attack and to enable a reduction in cement content. The objective of this study is to evaluate the effectiveness of various mineral admixtures in producing SCC. In this study the scope of GGBS ( Ground granular blast furnace slag ) as a mineral admixture to some percentage replace cement in SCC were studied. The study showed that a maximum of 50% GGBS were able to be used as a mineral admixture without affecting the self-compactability

In the search of new and efficient NLO material in organic element (Zn) doped L-Threonine organic crystal were grown in the present study. The grown crystals were characterized by measuring the density by floatation technique. The structure of the crystals were studied by FTIR spectrum. The lattice parameters of pure and doped crystals were calculated from SXRD and PXRD respectively. The lattice parameters shows the crystal belong to orthorhombic system

Organisations and corporate world have been searching for ways to enhance their businesses in order to be agile and how development in information technology (IT) can help them achieve this in today’s unstable economic climate. Large-scale changes in the business affect operations, which in turn impact business systems. Changes in the underlying technology infrastructure are often needed to enable business transformation. The study carried out shows that architecture is the key to managing complexity and scale of change in the business. The method used is the integration of the processes for strategic, business, operations, systems and technology planning in a way that also integrates with other business and technology governance processes. Enterprise Architecture provides a framework to describe, manage and align the various elements of an organisation such as business processes, information, applications and technology and enables to understand the relationships between these elements and their environment to better facilitate change. This article proposes enterprise architecture (EA) as an effective Tool to Business Innovation Realization in the Enterprise.
