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

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.
