Abstract

A sequential anode-cathode double-chamber microbial fuel cell (MFC) was constructed for the production of electricity using a novel microorganism, Clostridium sporogenes NCIM 5125 which is profoundly known to be a part of MFC studies. The growth of the microorganism was supported by energy derived from the electron transfer process itself and results in stable, long term power production. The electricity generation was optimized by analyzing the growth of the microbe at different parameters using mediated and non-mediated MFC. The results suggested that it is feasible to generate more electricity amounting to 5.6 mA at 160th h with the adopted C. sporogenes using mediated MFC.

Abstract

Self-Compacting Concrete is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. One of the disadvantages of self-compacting concrete is its cost, associated with the use of high volumes of Portland cement and use of chemical admixtures. One alternative to reduce the cost of self-compacting concrete is the use of mineral admixtures such as fly ash, ground granulated blast furnace slag and micro silica, which is finely, divided materials added to concrete during mixture procedure. When these mineral admixtures replace a part of the Portland cement, the cost of self-compacting concrete will be reduced especially if the mineral admixtures are waste or industrial by-product. Moreover, the use of mineral admixtures in the production of self-compacting concrete not only provides economic benefits but also reduces heat of hydration. The incorporation of mineral admixtures also eliminates the need for viscosity-enhancing chemical admixtures. The lower water content of the concrete leads to higher durability, in addition to better mechanical integrity of the structure. This paper presents an experimental investigation on strength aspects like compressive, flexural and split tensile strength of self compacting concrete containing different mineral admixtures and workability tests for different mineral admixtures are carried out. About 15% fly ash and 5% micro silica are used as a partial replacement for cement.

Abstract

Cement is the essential construction material for making concrete which provide good binding among aggregates and also provide high strength. But cement releases high amount of CO₂ during manufacture. In order to reduce the environmental menace and also to enhance the property of concrete  Palm ash based concrete are used. Palm ash based concrete containing palm ash as partial cement substitute. The partial replacement percentages are 10%, 20%, 30%. In this investigations properties such as compressive strength and durability strength of palm ash based concrete and conventional concrete are find out. Results are tabulated and discussed. The palm ash based concrete properties are also compared with the conventional concrete. The palm ash based concrete is very economical and also eco friendly concrete.

Abstract

The aim of this project was to determine the significance of lactate dehydrogenase (LDH), β2 microglobulin (β2M) and tumor markers in the diagnosis of lymphoma. For this purpose, 10 patients were taken for study, Median age 55 (35-75), male 7. Histopathologic diagnosis was B-cell lymphoma in 4 (50%), T-cell Lymphoma in 3 (37.5%). 2 patients (20%) were diagnosed with Hodgkin's Lymphoma. Diseases sites were para-aortic nodes (52%), cervical (8%), peripheral nodes (33%), others 6%. The patients were tested for LDH and β2 microglobulin levels in addition to tumor marker analysis.LDH and β2 microglobulin are prognostic indicators. They are also helpful in monitoring the disease during therapy by ascertaining the tumor burden.

Abstract

In this present study, the work deals with investigating the effects of bi-metallic nanoparticle in the base fluid (water). Copper nanoparticles were prepared by size control method and alumina nanoparticles (Al₂O₃) were purchased. Then by using the above nanoparticles subsequent nanofluids were prepared by two step method for the preparation of nanofluid. Uv Spectroscopy, X- Ray diffraction (XRD) and Scanning electron microscope (SEM) were done to characterize the nanoparticle. Bi-metallic nanofluid of Cu (core)/Al₂O₃ (shell) structure was synthesized and its thermal conductivity was measured. Then the experimental value of thermal conductivity was compared along with theoretical value, which is determined with the help of "Maxwell model for thermal conductivity for solid - liquid mixture" for low solid concentration. After preparation of nanofluid they were measured using KD2 PRO thermal conductivity analysis devices and for Copper Nanofluid the thermal conductivity was increased by 7% than the basefluid and for alumina, thermal conductivity was increased by 10% than basefluid. And Bi - metallic nanofluid, thermal conductivity was measured with the help of KD2PRO and there was 22% increase in the thermal conductivity than the base fluid.

Keywords

Nanofluids, Nanoparticles, Thermal conductivity, Bi-metallic.

Abstract

Buccal delivery refers to the drug release which can occur when a dosage form is placed in the outer vestibule between the buccal mucosa and gingival. This route has various advantages includes bypass of first pass metabolism, better enzymatic flora for absorption and patient compliance. Buccal drug absorption occurs by passive diffusion of the nonionized species. Mucoadhesion may be affected by a number of factors, including hydrophilicity, molecular weight, cross-linking, swelling, pH, and the concentration of the active polymer. There are two types of buccal dosage form,they are matrix type and reservoir type. The basic components of buccal drug delivery system are drug substance, bio adhesive polymers, backing membrane permeation enhancers. There are two methods for preparation of buccal patches include solvent castng method and direct milling method. The evaluation tests include surface PH, thickness measurement, swelling study, thermal Analysis study, morphological characterizayion, water absorption capacity test, Ex-vivo bioadhesion test, in vitro drug release, permeation study, Ex-vivo mucoadhesion time and stability study in human saliva.

Abstract

Transient stability plays key role for the loading of Extra High Voltage AC lines under their thermal limits. It is not possible to load these EHV lines near the thermal limits. But, with the proposed scheme in this paper, it is possible to load these lines very close to their thermal limits. Master current controller senses ac current and regulates the dc current orders for converters online such that conductor current never exceeds its thermal limit. In this scheme, the ac line conductors are superimposed with dc power flow and it doesn't cause any transient instability. This paper presents the converting of an ac line into composite ac-dc power transmission line to improve transient stability and damping out the oscillations. With Matlab/Simulink software the thermal limits are satisfactory and the gain in the load ability of the line is obtained.
