CENTRE FOR GRAND NAINE TISSUE CULTURE (CGNTC)

ABOUT GRAND NAINE(G9)

Grand Naine bananas are cultivars ofMusa acuminata. It is one of the mostcommonly cultivated bananas and asource of commercial (Cavendish)banana. Its characteristic mediumheight and large fruit yields make itideal for commercial agriculture. Themoderate height allows easyharvesting and some resistance towind throw. G9 can be produced inlarge numbers through tissue culturewith high yield and disease resistance.The Department of Biotechnology isaiming at producing and distributingtissue cultured plants to the ruralmarginal SC/ST farmers and otherfarmers of weaker sections in UdupiDistrict of Karnataka for the economicempowerment of the farmers. Theproject is funded by DBT, Ministryof Science and Technology, NewDelhi.

ACTIVITIES

The selection of plant was donebased on high yield, disease free,pest free and superior character ofthe plant.

In-vitro production of bananaplants was carried out. About20,000 banana tissue cultureplantlets were produced.

Training on tissue culturetechniques and hardeningtechnique were given to selectedwomen of Udupi district.

Tissue cultured banana plantletswere distributed to farmers ofUdupi district and demonstration ofcultivation practices was given.

BIOFUEL INFORMATION AND DEMONSTRATION CENTRE (BIDC)

SUPPORT FROM KSBDB

Karnataka State Biofuel DevelopmentBoard (KSBDB), Bengalurusponsored the establishment of theBiofuel Information andDemonstration Centre in the premisesof NMAMIT at Nitte and is run bythe Department of BiotechnologyEngineering. This centre is the Udupidistrict BIDC.

This centre is one among the 32Information and DemonstrationCentres instituted by KSBDB inKarnataka.

ABOUT BIO DIESEL

Biodiesel can be produced by any oilbut Karnataka Biofuel Policy restrictsit to non-edible oil and waste oil.More than 150 species of non-edibleoil yielding species have beenidentified by Karnataka State BiofuelDevelopment Board ( KSBDB), mostof which are region specific. The non-edible oil seed species that are grownin Udupi and the coastal region areRubber seed, Honne (Calophylluminophyllum), Nagachampa, Amura,Shanti (Terminalia bellerica), Naikulior Buguri (Sclerophyllum pentadrum)and many more. These seeds arealready available in large quantities incoastal region and are having no orminimal commercial application.These seeds are potential feedstock for biodiesel production.Aforementioned seeds are purchasedfrom farmers for a reasonable price.

Inauguration of UBIDC at Nitte

Udupi district BIDC is responsible forproduction of biodiesel from variousnon-edible oil seeds available in Udupidistrict, create awareness,disseminate information aboutbiofuels amongst the scientificcommunity, students, farmers andpublic and give demonstration, andprovide technical know-how aboutbiodiesel production. The objectivesof BIDC also include developingplantation of local breeds of biofuelplants, conduct research on biofuelprocesses and also involving NGOsin the awareness programs. Thebyproducts of biodiesel productionsuch as cake and glycerol have

commercial application. Oil cake canbe used as manure in the farm,whereas some oil cakes (non-toxic)can be used as cattle feed. Glycerolis used in soap making. Productionof biodiesel from locally availablenon-edible oil seeds and its utilizationgives eco-friendly fuel, adds revenueto the farmers, saves foreignexchange, reduces dependence onforeign countries for fuel andimproves rural employment.

FACILITIES

The BIDC at Nitte has a capacity ofproducing 50 liters of biodiesel perbatch which requires about 10-12working hours. Biodiesel is producedthrough a chemical reaction called astrans-esterification. The oil is firstextracted through a mechanicalexpeller. The oil is then treated withmethanol at 60oC in presence ofsodium hydroxide. Then producedbiodiesel is separated and purified forengine use. UBIDC also houses atesting lab for Biodiesel testing wheremajor 5 parameters (Acid value,Viscosity, Density, Flash point andCopper strip corrosion) are tested.Biodiesel can be used in any dieselengine without modification andbiodiesel can be used in blending withmineral diesel. Biodiesel can be usedin vehicles, DG sets, tractors, pumpsets etc.

To maintain an optimumspark gap for stable machiningcondition, tool should be fed at a rateequal to the sum of Material RemovalRate (MRR) and Tool Wear Rate(TWR). Since the optimum spark gapis few micrometers, a precise controlover the tool feed is essential in micro-EDM.

ABOUT MICRO MACHINING

Micro systems find wide applicationsin bio-medical electronics, optics,micro-mechanics, micro fluidics,dies, moulds etc. Component partsused in these systems have featuredimensions in micrometers andpart volumes less than 1 mm3.Manufacture of these componentswith high accuracy is a challenge.

THRUST AREAS

2. Tool based Mechanicalmicromachining

Tool based mechanicalmicromachining technology is gainingimportance in Micro-ElectroMechanical System device fabricationbecause of its ability to machine 3Dmicro features on differentengineering materials.

achieved by contact sensing and tooldisplacement is obtained by a Laser-Optical Displacement MeasuringSystem (ILD 1402-10, Measuringrange 10mm, 1 micrometerresolution, from Micro-Epsilon,Germany).

The tool based mechanicalmicromachining center withpiezoactuated workpiece feedingsystem has been developed. A highspeed spindle (HSS) is used to rotatethe micromilling/drilling tool at a speedof 12,000 to 60,000 rpm. Athermoelectric based liquid coolingsystem is developed to control thetemperature of the high speed spindleat a set value. Along with the X-Ypositioning system, the workpiece isalso mounted on a piezoactuator toprovide Z-axis motion duringmachining operation. An electricalcontinuity based tool-workpiececontact detection system isdeveloped to overcome prematuretool failure during initial toolregistration with the workpiece.Based on the developed tool-workpiece contact sensor, an in-situmeasurement system is developed tomeasure the micromachining depth.Experiments have been conducted tomeasure the performance of spindlecooling system and in-situmeasurement system.

ABOUT VIBRATION ISOLATION

Many industrial processes andequipment demand for activevibration isolation systems for theiraccurate functioning. Vibrationisolation are of 2 types namely activevibration isolation and passivevibration isolation. Passive vibrationisolation refers to vibration isolationby passive techniques such as rubberpads or mechanical springs. Activevibration isolation refers to vibrationisolation by employing electric power,sensors, actuators and controlsystems.

THRUST AREA

An active vibration isolation systemis developed using stackedpiezoactuator. Amplitude andfrequency of disturbing vibrations aremeasured in real time and a vibrationsignal out of phase by 180 degreesbut of the same frequency is generatedto nullify the induced vibration usingstacked piezoactuator.

DESCRIPTION

In active vibration isolation system,two piezoactuators are used. The firstacuator is used to induce the vibrationwhereas the second piezoactuator isused for generating a vibration whichis 180 degrees out of phase with thedisturbing vibration. This will ensure

Apart from the research activities, thestudents are encouraged to developR&D skills through a variety of clubsand participating at the national andinternational levels, as given below: SAE Baja Robotics Aero modeling

SAE Baja: To successfully design,build, and race a Society ofAutomotive Engineers (SAE) Baja car,there are a variety of challenges. In2013, a new SAE student team wasformed at NMAMIT. The primarypurpose of this club is to help theengineering students develop theknowledge and skills necessary tobecome competent engineers. Manystudents join this club in their freshmanyear as the development of theirengineering knowledge andmanufacturing skills must happen inrapid pace for them to make a solidcontribution to the team. The SAEBaja project provides ampleopportunity and motivation forstudents to engage in problem-basedlearning.

The Baja SAE program at NMAMIThas been an effective tool for teachingproduct design and development in arealistic setting. The project motivatesstudents to learn about design andmanufacturing. It also teaches the
