The H.O.D of Civil Engineering department Dr. Sudhir Kumar of MNIT had something to say to his students. Let’s take a look into what he awaits from his students. “I expect the students to actively participate in all of the departmental activities or the institutional activities if possible. They should come forward for organizing the depart-mental events and develop a culture where every student gets a chance to manage, or-ganize or participate in the departmental activities. Every student should have a capabili-ties like management, leadership etc. Also, students should come forward with innovative ideas of projects and take a stand on development of standards of laboratories. They should have regular interaction with the alumni association’s members for learning from their experiences. I am yet to see students organizing departmental events such as conventions, seminars, paper presentations, workshops etc.

In the matter of studies, every single student should have a mastery over at least one

instrument be it of any lab such that he is able to tell anything from working to construc-

tion of the instrument. Spending time in the lab for its development will definitely facilitate

such mastery as the student will always be surrounded by them.”

A solar roadway is a road surface that generates electricity by solar pow-er photovoltaics. The concept involves replacing highways, roads, parking lots, drive-ways, and sidewalks with solar panels and LED signage, that can be driven on. Park-ing lots, driveways, and eventually highways are all targets for the panels.

The main advantage of the solar roadway concept is that it utilizes a renewable source of energy to produce electricity. The life span of the solar panels is around 30–40 years, much greater than normal asphalt roads, which only last 7–12 years. In the event of an environmental disaster or military emergency, solar roadways would provide power when it is needed most. As solar power is renewable, it obvi-ously requires no external connection to an artificial power source. Another advantage of solar roadways is that they do not re-quire the development of unused and po-tentially environmentally sensitive lands since the roads are already there. Trans-mission lines could simply be run along already established roadways. With induction plating embedded inside these roads, electric cars can be recharged while in motion on top of these roads. This would reduce the costs and the time-inconvenience of waiting at a charging station. In spite of these advantages, initially, the start up and maintenance costs of building such roadways and parking lots may be extremely high. Another issue to deal with is the efficiency of solar panels. The average efficiency is currently 20%. Another disad-vantage is that solar road panels cannot easily be constructed in the poorest develop-ing nations due to the high initial start-up costs.

The use of Solar Energy offers huge potential today.

The Advantages of SOLAR CELL PANELLED ROAD-WAYS are:-

It is Renewable form of energy and has a larger life span.

It provides Military and medical assistance in cas-es of emergency.

Solar roadways provide On the go charging.

Why did it fail?

Lack of redundancy.

Inadequate or badly posi-tioned reinforcing.

Steel struts embedded too far in concrete shell

Weakened concrete shell support beams due to the passage for ventilation ducts.

Poor design and response to temperature variations that existed in the outer metal part .

The St. Francis Dam was designed by William Mulholland, chief engineer for the Los Angeles Department of Water and Power. It was a curved concrete gravity dam. By definition, a gravity dam is one where that depends upon the force of gravi-ty to prevent it from being pushed aside by the water it contains. Essentially, the force of the water behind the dam is pushing the dam to tip forward upon it’s toe. The weight of the dam is acting against that, causing it to rotate downward into the earth from the same point. But what caused the St. Francis Dam to fail was a limited understanding of the geological foundation of the dam. In the 1920s, when the dam was built, the technology wasn’t available to properly determine the strength of the paleo-mega-landslide rock formations that the left abutment rested upon. This was the major contributing factor to the failure of this dam. Also, earlier in the day of the failure, Mulholland examined a leak in the dam. Leaks in concrete dams are not uncommon, and this one was found to be inconsequential. Since the failure of the dam was mostly caused by the subterranean rock, the only way that that leak could have been an indicator, would be if it was large enough to demonstrate the shiftin of dam’s foundation .

The disaster resulted in a number of changes to civil engineering, specifically to the area of dam design and construction, as new federal standards for the construction of dams was implemented and an increased awareness of the geological factors in civil engineering came to light from the failure of the dam’s foundation. Geotechnical engineering can trace its roots to this disaster. Today, geologic input on dam design and construction is commonplace. The importance of peer review of designs was brought to light. Since this time, a project of this size has never been designed and overseen by only one engineer. The lessons learned from this tragedy have helped ensure that later projects are much less prone to failure.

William Frazier Baker, also known as Bill Baker, is an American structural engi-neer who has dedicated his career to structural innovation. He is widely known around the world for developing the buttressed core structural system and for his work on super tall buildings. Baker is credited with the design of three out of four of the tallest buildings to “top-out” in 2009: Burj Khalifa , Trump International Hotel and Tower and the Nanjing Greenland Financial Center. Born on October 9, 1953 in Fulton, Missouri, Baker obtained a bachelor's de-gree in civil engineering from the University of Missouri, and then held a brief tenure with ExxonMobil. Later he completed his master's degree at the University of Illinois. He then joined the architecture and engineering firm of Skidmore, Owings and Merrill (SOM) in Chi-cago in 1981, eventually becoming a partner in1996 and now he is a licensed professional engineer in 40 states. In 1999, his next-generation, stayed-mast structural system for the proposed 7 South Dearborn, a 610-meter (2,000-foot) tall, 118- story tower built on only one acre, in-corporated structural engineering advances that demonstrated how modern wind engineer-ing and materials can be used to achieve slender towers of unprecedented height. Baker continues to push the boundaries of form and science with its neighbor, the twisting, 73-story Infinity Tower. He is best known as the engineer of Burj Khalifa (Dubai, 2009). To support the tower's record heights, he developed an innovative structural system "buttressed core" , consisting of a hexagonal core reinforced by three buttresses that form a Y shape which allows the structure to support itself both laterally and torsionally. It also eliminates the need for column transfers, and moves loads in a smooth path from the tower's spine into its foundations. Baker's expertise also extends to a wide variety of structures like the Broadgate-Exchange House (London), and the GM Renaissance Center Entry Pavilion (Detroit). He is also regarded for his work on long span roof structures, such as the McCormick Place North Building Expansion (Chicago), the Korean Air Lines Operations Center (Seoul), the Korea World Trade Center Expansion (Seoul), and the Virginia Beach Con-vention Center (Virginia Beach). His belief that the exterior form of a high rise should be a direct expression of its

structural framework; where, in the best instances, great structural and architectural collaboration results in situa-tions where one cannot describe the structure without the architecture, and the architecture without its structure. Baker's many skyscraper projects include the AT&T Corporate Center (Chicago, 1989), Trump Internation-al Hotel and Tower (Chicago, 2008), Infinity Tower (Dubai, 2009), Pearl River Tower (Guangzhou, 2009), Nanjing Greenland Financial Center (Nanjing, 2009), and the unbuilt 7 South Dearborn (Chicago, 2003) securing his inter-national reputation as a structural innovator. He is a Fellow of the American Society of Civil Engineers (ASCE), the Institution of Structural Engineers (IStructE) and the member of the National Academy of Engineering (NAE). In 2011, Bill Baker received an honorary doctorate in engineering from the University of Stuttgart and an ASCE Outstanding Projects and Leaders (OPAL) Lifetime Award for Design. On May 13, 2010, The Institution of Structural Engineers, awarded Baker with the Gold Medal, the Institution's highest accolade. Baker was the first American to be awarded the Fritz Leonhardt Prize For Achievement in Structural Engineering on July 11, 2009. On November 20, 2008, Baker received the The Fazlur Khan Lifetime Achievement Medal from the Council on Tall Buildings and Urban Habitat.

An American structural engineer dedicated to innovations in structural engineering, Bill Baker is most widely recog-nised as the lead de-signer of Burj Khalifa.. He is a fellow of ASCE, IStructE and the mem-ber of National Acade-my of Engineering. Baker was the first American to be award-ed the Pritz Leonhardt prize for his achieve-ments in Structural En-gineering.

Can a skyscraper produce more energy than it consumes? It is designed to be one of the most environmentally friendly buildings in the world. The building is de-signed with energy conservation in mind, including wind turbines and solar collectors, photovoltaic cells, raised floors ventilation, and radiant heating and cooling ceilings. It is arguably one of the most environmentally friendly buildings in the world. Pearl River Tower is a 71-storey, 309.7 m (1,016 ft), clean technology sky-scraper at the junction of Jinsui Road/Zhujiang Avenue West, Tianhe District, Guang-zhou, China. The tower's architecture and engineering were performed by Skidmore, Owings, and Merrill with Adrian D. Smith and Gordon Gill , as architects It’s the first ever building to combine structure with aerodynamics and the first to utilize a multitude of energy efficient technologies in one single structure. With a design specific to its environment, the Pearl River Tower symbolizes the future for super-tall building de-sign.

Architecture and design The design of the Pearl River Tower intends to set new standards for skyscrapers: a high-performance structure designed in such harmony with its environment that it ex-tracts energy from the natural and passive forces surrounding the building. Some of the major accomplishments are in the nature of the formal and technological integra-tion of form and function in a holistic approach to engineering and architectural design. With a curved facade that faces directly into the wind, the Pearl River Tower in China’s Guangzhou City is shaped for performance.

Sustainability Among its features are turbines that turn wind into energy for the HVAC system, solar collector for more power generation, a rainwater collection system, part of which is heated by the sun to provide hot water. The building is cooled, in part, through heat sinks and vertical vents. The turbines do more than generate electricity, though. The openings through which the wind flows help reduce the overall wind load on the sky-scraper. The Pearl River Tower is one of the first in a new generation of super smart buildings. It will use less than half the energy of a conventional skyscraper and will harvest the forces of nature to make energy of its own.

Of the Pearl River Tower’s accomplishments, many are related to the most innova-tive of sustainable design features including:

The tower is an example of China’s goal to reduce the intensity of carbon dioxide

emissions per unit of GDP in 2020 by 40 to 45 percent as compared to the level of 2005.

The pearl tower is the largest radiant-cooled office building in the world.

In present times it is the most energy efficient super-tall building in the world with

over 90% of its energy requirements met by it on it’s own.

Factoids:- The building is designed to be 58% more energy efficient than requirements stip-ulated by local building codes. At completion, the tower was designed to be the world's most energy efficient super-tall tower ever built. The building's orientation was dictated by the direction of the prevailing wind. Features chilled ceilings and a roof lined with solar panels. Building has two major mechanical floors where turbines generate electricity from the wind blowing through the floors. The aerodynamic reclining of outer surface ensures high velocity flow into the turbines even at as slow wind velocities as 10kmph, so that the turbines installed are always engaged in their task, i.e. to produce electricity.

Clean technology includes recycling, use of renewable en-ergy , IT advance-ments, green trans-portation, electric mo-tors, green chemistry, and efficient lighting. It is a means to create electricity and fuels, with a smaller envi-ronmental footprint to minimise pollution.

Asia’s first “Signature Bridge” being constructed across the Yamuna river at Wazirabad promises to be one of the greatest attractions of Delhi. It was initiated with a plan of mak-ing this a landmark bridge, the surrounding areas are to be developed as tourist destina-tions. Connecting east and west Delhi with an iconic bridge in the historical capital of India, it

symbolizes the rising aspirations of modern India. This extraordinarily engineered Signa-

ture Bridge, showcased in the midst of large water body, specifically landscaped with

wooden surroundings, will serve as a unique tourist destination.

The project is divided into two parts, approach and main bridge. The work on the ap-

proaches started in June 2008. The boomerang shaped pylon provides, to a substantial

extent the stress balance required for supporting the deck. It also contains elevators and

stairs for reaching the top of the pylon, where a visitors’ gallery for obtaining a full view of

Delhi is planned. The pylon shows two inclined legs rigidly connected to the deck which

meet at half height. The upper single leg of the pylon contains the cable stay anchorages

and the visitors gallery.

Two high towers will be placed on the inner periphery of the carriageway to provide dou-

ble support. The decks will be composite (steel and concrete) while the pylon will be of

steel. The composite deck consists of 2 main girders and cross girders at 4.5 m spacing

with 25 to 60 cm concrete slab on top.

The cable stayed bridge connects to National Highway 1 near existing T-point at Wazira-bad on Western bank and Marginal Bund Road at Khajuri Khas on eastern bank of the river Yamuna. A tourism and recreation project has been planned on 1,000 acres of land alongside the bridge. Apart from a theme park for children, a water body is also being de-veloped around this bridge for water-sports enthusiasts.

Once operational, the Signature Bridge will dramatically improve access between North

and West Delhi, with a free flow of traffic even in peak hours and ensuring that compen-

satory plantation is taken up to eliminate any loss to greenery. One of the principal contractors of the project GAMMON INDIA has documented the pro-ject since its conception. Salient features:

Graphics on bridge structure is featured for the first time in the world. The pattern chosen reflects Indian culture and at the same time symbolizes a modern and progressive India.

Sheer scale and dynamics of the bridge, clubbed with cutting edge technolo-gy used in designing it will make it a contemporary landmark for the city of Delhi and also in the world.

On mega scale the project attempts to integrate and curb water pollution and encourage the Yamuna water cleanup in turn, providing a water front worthy of tourist activities.

The bridge has been designed as the tourist destination by developing area around the bridge into public plazas and parks and made accessible to the common public in general.

Once completed the bridge will help in changing the socio-economic and cultural fabric of the area by attracting large number of tourists– local, nation-al and international.

But as is the case with projects of such a sheer scale the delay has caused the project cost to escalate from original estimates of Rs 460 crores to a total cost of Rs 1,131 crores to the government exchequer. The web resource could be found out at

Signature bridge-the new symbol of Delhi-NCR and its two ap-proach roads, together called the Wazirabad bridge project (proposed in 1997), includes a main cable stayed bridge, the western and eastern ap-proach roads, pedestrian subways, road signages, landscaping and horticul-ture work. The proposed bridge is being construct-ed across Yamuna, 600 meters downstream from the existing barrage at Wazirabad juncture.

Hamburg's wastewater management system based on gravity sewers goes back to the British engineer William Lindley. Gravity sewers require large amounts of water to transport the feces together with other wastewater to the central wastewater treatment plant. In Germany however, the drinking water demand is decreasing, which lessens the flow in the sewer line, and thus makes the transport of sewage to the sewage treatment plant more difficult. There, 450,000 cubic meters of wastewater - equaling about 2.9 million population equivalents - is treated daily. This central plant is one of the larg-est and most modern in Germany.

After treatment the clean water is discharged into the river Elbe. Also nutrients like phos-phorus and nitrogen are removed. These nutrients are indispensible for agriculture, yet harmful in water. Nutrients like phosphorus and potassium are only finite resources and are usually not recovered in conventional wastewater treatment. HAMBURG WASSER aims at closing these loops with energy-efficient technologies and sustainable concepts. For this reason the company has developed the HAMBURG WA-TER Cycle as an innovative and holistic wastewater and energy concept, which effi-ciently can be integrated into the existing system. The HAMBURG WATER Cycle offers a concept for decentralized wastewater management recovering nutrients and generat-ing renewable energy. The HAMBURG WATER Cycle (HWC) concept provides a holistic approach to both the energy supply and sanitation needs in urban areas. In this approach, the complimentary areas of water and energy infrastructure become interdependent, simultaneously pro-tecting water resources and utilizing wastewater to produce energy. Thus, it is possible to close the material cycles directly in the residential environment. The most critical component of the HWC is the separate treatment of the different wastewater streams, the so-called partial flow treatment. Storm water, wastewater from the toilet, and wastewater from the kitchen and bathroom (when washing hands or using the washing machine for example) are separately collected and then separately treated.

In the end of the year 1999 a new concept for Hamburg's wastewater treat-

ment plants was commissioned to cope with the additional load of 250,000

PE which has been connected to the existing plant serving 1.85 million

population equivalents. The new concept consists of an additional tank for

the storage of sludge liquor to avoid peak nitrogen concentrations in the

effluent of the plant. This solution has been developed within a study as-

sessing a wide range of concepts with costs between initial 100 million and

the final construction costs of 1 million. Here the dynamic simulation

showed to be a very efficient planning tool. Within the first three years of

operation the chosen solution showed to be able to fulfil the requirements.

In 2002 the concept has been improved by a few more measures, mainly the equipment of one of the storage tanks

as a SAT tank for further cost effective nitrogen removal. For a further improvement of the treatment capacity addi-

tional measures are planned to be carried out within the next years.

In fluid mechanics, the Reynolds number (Re) is a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions and so used to characterize different flow regimes, such as laminar or turbulent flow: laminar flow occurring at low Reynolds numbers, where viscous forces are dominant, which is characterized by smooth, constant fluid motion; while the turbulent flow occurs at high Reynolds numbers and is dominated by inertial forces, which tend to produce chaotic eddies, vortices and other flow instabilities . The Reynolds number is de-fined as :-

An owl's head, can twist so far round that it faces backward... but when the bird wants to look forward again, it must turn its head back the way it came. And this is not just a biological problem. Even human engineers have difficulty with it, which is one reason why revolving buildings—with their need for water, sewerage, gas and electrical connections—are so rare. But that could now be changing. The simplest approach to such a building is what might be called the owl solution—in other words, incomplete rotation. This allows fixed but flexible connections to be used. Some years ago Bill Butler, an amateur architect, used this trick in a house in Snow Creek, California. Water and gas are delivered, and sewage removed, via vertical steel pipes in the non-rotating base. Rubber hoses connect the uprights to their mates in

the mobile part of the building. The house's ability to rotate is thus limited only by the length of the hoses at full stretch. In the case of Mr. Butler's dwelling, that allows it to sweep out an arc of 120º. Rather than using rubber hoses to connect the stationary and moving parts of the building, 3sixty's ingenious plumbing system employs horizontal ring-shaped pipes made of steel. Or, rather, it employs two ring-shaped half-pipes that rotate with re-spect to one another (the lower one remaining fixed while the upper one revolves along with the building). The joints between the half-pipes have rubber seals to stop the contents from leaking, and each half-pipe has a vertical pipe connected to it, to introduce or dispose off the fluid concerned. Electricity, meanwhile, is delivered via a conductive brush that sweeps around a metal ring in the stationary base. A couple of bespoke houses does not amount to a trend. But larger commercial de-velopments are under construction, too. Constructed in April 2001 Suite Vollard in Curitiba, Brazil, built by Moro Construções Civis can be seen as major step in the direction. Each of the 11 apartments occupies an entire circular floor, and revolves at the occupant's command, in either direction, once an hour. The Suite Vollard is a futuristic residential building in Curitiba, Paraná, Brazil. It is the world's first spinning building. Opened in 2001, the Suite Vollard was constructed by Moro Construções Civis LTDA. The architect was Bruno de Franco. It was built in the Ecoville District in Curitiba, and has since became a fa-mous, well-known building in the city. The floors each have double sheets of glass on the façade, tinted silver, gold, or blue, depending on the floor. This provides "a spectacular effect" as the floors rotate in opposite directions. The bottom floors of the building are mostly an executive center. Each of the 11 floors, comprising the majority of the building, can rotate clockwise or counter-clockwise, with a full revolution of 360 degrees taking an hour. Each apartment was

sold for approximately Rs 15,000,000.00 ($US 300,000.00). The Suite Vollard apartment complex is named after Pablo Pi-casso's collection of etchings, the Vollard Suite, which was held on display when the building was inaugurated.

The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design. The requirements of mix ingredi-ents are : a ) The minimum compressive strength required from structural consideration b) The adequate workability necessary for full compaction. c) Maximum water-cement ratio and/or maximum cement content. d) Maximum cement content to avoid shrinkage cracking due to temperature cycle in mass concrete.

“In July 2014, I presented my research paper in the prestigious triennial ‘Indoor Air’ conference. It is a flagship conference of the International Society of Indoor Air And Quality (ISIAQ) and was held this year in the University of Hong Kong, Hong Kong. It saw participation from 56 countries and gave me an opportunity to interact with stalwarts in the field of Indoor air quality, pollutants and health. It was wonderful to attend the sessions of Dr. William Nazaroff (University of California Berkeley, California), Dr. Lidia Morawska (Queensland University of Technology (QUT) Brisbane, Australia), Dr. David Cheong (NUS, Singapore) and several others, whose papers I have liberally referred to, in my PhD research work. I was awestruck to see the intense preparation of the organizers and com-mitment of scores of super zealous students who left no stone unturned to ensure that the proceedings go smoothly. Around 1100 papers were presented at the conference between 7

th to 12

thJuly 2014. Every session was conducted, sharp at

the scheduled time. There were poster presentations, group discussions, exhibi-tion of air quality equipments and much more. Over all, the conference was a great experience. I seized an opportunity to sneak to the blissful ‘Macau’ which has been on my travel wish list, ever since Miss World competition was organized there. Hong Kong boasts of the world’s largest fleet of ferries between HK, Macau and other neighboring Chinese cities. The only words that come in the mind when you step on the Macau Island is OH MY GOD!!!. It took me several pinches to believe that I was actually moving in ‘Venetian’ which I have adored in few Hollywood movies (the civil engineer in me took less than a moment to recognize the sharp resem-blance that Kingdom of Dreams, Gurgaon has with interiors of ‘Venetian’, Macau ha ha ha…). There are several other places of tourist interest in HK like ‘the Dis-neyland’, ‘Madam Tussad’s wax museum’, ‘the Ocean Park’, ‘the Buddha’ etc. which I couldn’t explore because of shortage of time. However, the experi-ence at ‘The Peak’ is amazing. The view of Hong Kong up from ‘The Peak’ and the shopping opportunity there are truly enthralling. Hong Kong has most sky-scrapers in the world, with 8000 buildings having more than 14 floors (almost dou-ble that of New York). Mongkok has the world’s highest population density with an average of 1,30,000 persons per sq km. Fengshui plays a key role in shaping architecture, business and lifestyle in HK. Language is a big issue as most people speak only Cantonese and barely understand or speak English. Food is a also a major issue, as we literally had to struggle for a vegetarian meal and often had to be contented with only burger buns and cheese at Mc Donalds or bland Dimsums and Tofu wraps. So my dear students, Honkong is calling with all its glamour, cou-ture and wonderful business opportunities [remember, there is no visa required for 14 days] MY BEST WISHES!!!!!! “ -Dr. Nivedita Kaul Assistant Professor Department of Civil Engineering

Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distin-guish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. An example from house-building illustrates the process of prefabrication. The conven-tional method of building a house is to transport bricks, timber, cement, sand, steel and construction aggregate, etc. to the site, and to construct the house on site from these materials. In prefabricated construction, only the foundations are con-structed in this way, while sections of walls, floors and roof are prefabricated (assembled) in a factory (possibly with window and door frames included), transport-ed to the site, lifted into place by a crane and bolted together. Advantages and characteristics

Drafting & Designing AutoCAD — The most popular drafting software developed and sold by Autodesk is also one of oldest drafting software in the industry. With its first release dated in De-cember, 1982 the latest version of this flagship design program AutoCAD 2014 is the 28th release. While this software serves the basic purpose of drafting, more dedicat-ed suite for civil engineering is AutoCAD Civil 3D. This package supports Building Information Modelling (BIM) workflows along with drafting and documentation. FreeCAD— As the name suggests, FreeCAD is a free general purpose 3D CAD modeller. Although this software is utilized by mechanical engineers the most, but it also fits in civil engineering industry. This software is in beta stage but downloads are available for all major platforms on its website. Revit structure — This product by Autodesk is capable of 4D BIM. The tem 4D refers to the fourth dimension, time. It helps in designing the structure and visualizing it over a duration of events and activity during the construction process. It vastly improves the construction management and delivery of the project.

MNIT, Jaipur is not just about technical skills or opulent placements. Being a world leader in higher education, students of this prestig-ious institution develop cognitive intelligence, emotional intelligence, spiritual intelligence and most importantly social intelligence. Showcasing their skills and a strong will to contribute to the society, 60 bright students of

MNIT, Jaipur came together to form a social group - PANKH and participated in REFORM'N'ATION, an event organized at the Techfest of IIT Bombay. Spanning a period of two months the group conducted 100 tasks including Medi-cal camp in Rajeev Nagar ,Awareness camps in the institute , Cloth collection camp ,books and toys donation camp in Malaviya Nagar, street play at Jawahar Circle and Gaurav Tower and received wide appreciation and encouragement

from all sections of the society. The initiative started with an intent to win but with time metamorphosed with an intent to con-tribute. The whole Institute, from students to staff, dwelt deep into the mood of social empowerment. And to everyone's surprise, a seemingly difficult task turned out to be a blessing in disguise. These were one of the most memorable moments for all those who were associated with it.. But this initiative will not have a substantial change in the society if this group of 60 students does not become a group of 600 and then the entire MNIT family.

As we all know that on every 5th of

September in the memory of Dr.

Sarvepalli Radhakrishnan we cele-

brate teachers' day .The year by

gone saw, as a mark of gratitude to

our beloved teachers the students celebrating teachers' day for two days

i.e 20th and 23rd of September 2013 .

For the evening of 20th September we had a tree plantation drive in our

civil department courtyard where we embarked our voyage of making the

campus green and clean. It was inaugurated by Prof. Sudhir Kumar, H.O.D. of Civil Engineering Department.

After that we had a sports eve for our teachers in which there was three match series of volleyball , badmin-

ton ,billiards and many more sports. It was followed by a cultural night celebration on 23rd of September, which

had lots of cultural activities for the teachers as well as for the students .The night included blend of music with

dance and melodious songs sung by the students. Alongside there were interesting games for the teachers.

All the teachers present there per-

formed, too came out from their com-

fort zone of teaching and showed their

great talent and vocation through their

singing ,poem compositions skills and

a lot more . Here we have some

glimpses of the day of celebration.

“It is the supreme art of the teacher to awaken joy in creative expression

and knowledge.”

-Albert Einstein

Know Your Labs…Part 2

Laboratories form an integral part of good technical education. And we are lucky to have state of the art labs equipped with latest instruments and apparatus in our Civil Engineering Department. This series explores the number and capacity of our labs.

Road Material Testing Lab Transportation Engineering is one of the Core subjects for a civil engineer, especially when its case of designing and constructing efficient transport networks. The concrete-mix design and road materials testing play a very important part in determining the very functionality and durability of the road as a whole. Our lab is furnished with all the latest possible equip-ments and is a hub for research scholars and industries and government organisations which depend on it for testing and consultancy.

A STUDY OF TEMPORAL VARIATION OF WATER INFLOW TO RAMGARH AND BISALPUR DAM

Declining trend of water inflow is being observed in the dams of Rajasthan state, which is impacting on the water supply planning of the state. Rajasthan is a semi arid state; it faces acute water shortage in most of the years. The variation of water inflow in the dam creates a very sensible situation for the Government of Rajasthan.

A paper entitled "Helpline for water leakages: A solution to the water crisis." was published and presented in the India Water Week-2013 organized by Central Water Commission, Minis-try of Water Resources, Government of India. Paper entitled "Feasibility analysis for construc-tion of new dams in Rajasthan State." was submitted to the Central Board of Irrigation and Power, thereafter approval it was sent to the International Commission of Large Dams. The paper was accepted for publication and presentation at ICOLD-2014 at Bali, Indonasia. Paper entitled "Declining Trend of Water Inflow in the Dams of Rajasthan State" was published in International Journal of Technology (2014) 1: 14‐21.

This research work is being conducted by Naveen Kumar Gupta (2011RCE7135) under guid-ance of Dr. A.S.Jethoo, Associate Professor of Civil Engineering Department, MNIT, Jai-pur. Presently research scholar Naveen Kumar Gupta is working as Executive Engineer in Water Resources Department of the Government of Rajasthan.
