  In recent decades, microalgae have acquired attention from pharmaceuticals to biofuels. The growth and total chorophyll content of three economically important microalgae (Chlorella sp. NTAI01, Monoraphidium sp. NTAI02 and Scenedesmus sp. NTAI03) isolated from fresh water body in five selected culture media on different days of incubation was studied for biomass production. Biomass feedstock has reviewed great interest to be used as an alternative and renewable source of energy. All the three organisms showed varied growth pattern and total chlorophyll content in different culture media. However the growth and total chlorophyll content of Chlorella sp. NTAI01 and Monoraphidium sp. NTAI02 was optimum in Half strength Chu 10 medium. In case of Scenedesmus sp. NTAI03 the growth and total chlorophyll content was found to be significant in Bold’s Basal medium. The Acidified Bold’s Basal medium and BG-11 medium fairly supports the growth of all the three microalgae whereas the Modified Hoagland’s medium does not support the microalgal growth. The optimized growth medium will be used for biomass production for biofuel application.

  Azolla-Anabaena symbiosis is one of the vital roles in the field of agriculture and development. Both the associates have mutualistic relationship and work together for carbon and nitrogen fixation to soil. The present study is to investigate the new entity in the relationship between the Azolla and Cyanobacteria. Endophytic and Epiphytic cyanobacterial associates were isolated from different Azolla sp. viz., Azolla pinnata, Azolla caroliana and Azolla filliculoides. The isolates were further characterized by conventional methods and molecular techniques. A novel entity, Westiellopsis was found in the association with Azolla filiculoides comparatively with previously reported. Furthermore, Anabaena variabilis precluded from Azolla filiculoides was produce red color pigmentation. The C-Phycoerythrin content of the isolated cyanobacterial symbiont was measured by absorption and fluorescence emission spectroscopy. The nutritional optimization was done showed two fold increased in pigment production than the control.

  Researchers and scientist have challenge to decrease the immense use of synthetic fibre like glass fibre and carbon fibre and its composite’s cost. Natural fibres alternative for synthetic fibre was reinforcement composites for good environment. Natural fibres have more benefits such as less money, renewability and etc. The spirit, enormous fabrication and economic properties of jute fibre selected us for this project. This study is focused on mechanical properties of jute fibre reinforced composites. The mechanical properties are obtained from the testing such as tensile, compression and impact. And all results are comparing with the other samples.

  The standards of projective geometry. The parameters of geometry characterizing the different cutting apparatus edges are depicted by methods for taking proper projections of the cutting device surfaces. Advancement in the field of PC Aided Geometric Design (CAGD) now give more rich way to deal with indicating the cutting apparatus surfaces as an arrangement of biparametric surface patches. This investigation of machining procedures includes examining the chip development prepare. A long time of research has indisputably demonstrated that it a procedure including plastic twisting in which extensive strains and strain rates are created by restricted shear distortion of work material instantly in front of hardware. Warm produced amid the chip arrangement prepare accordingly of plastic twisting and rubbing.

  The point of the research is to model and examination the tyre coupling with a scope of material together with the existing material substitution and the physical and mechanical properties of the coupling which is utilized as a part of operation of draw in and separate of wheels tyre with the contact. The material utilized as existing in tire coupling is outlined and examination is surrendered out with correlation of proposed material. The results are plotted and talked about.
