UCG
UCG typically consists of two adjacent bore holes drilled into a coal seam and pressurized oxidants such as air or steam are used for ignition of coal seam. The oxidant and the gasifying agent are fed through the injection borehole and the combustion and gasification products are recovered from the production bore hole. Injecting oxygen and steam instead of air produces the most useful product gas, since the dilution effect of nitrogen is avoided. The main constituents of the product gas are H2, CO2, CO, CH4 and steam. The proportion of these gases varies with the type of coal and the efficiency of the gasification process. UCG requires an understanding of various aspects of the selected site. The geology, hydrology, mining, drilling, exploration, chemistry and thermodynamics of the gasification reactions in the cavity are important parameters for successful operation. An exchange of knowledge between the various fields is necessary. Before starting UCG, many issues should be considered. Some of them are: 1. Exploration of the UCG site. 2. Choice of a suitable drilling technique. 3. The gasification process (air blown versus O2 blown). 4. The use of the UCG product gas. 5. Environment and safety. 6. Economics.

NH 58
Risks Injury to the Human Resources(Skilled or Unskilled): During the course of construction there might be sudden or unexpected happenings that might cause injuries(due to faulty or improper use of machinery )or might even prove to be fatal for the workers, engineers, company executives or any civilian as well. Adverse Environmental Impact of The Materials Used in Construction: The materials used in construction for example the fillers used in highway might not be environment friendly and not get the approval from the environmental authorities supervising the project. Unexpected or Sudden Failure of Machines or Equipment During Construction: The machines or equipments might suddenly break down during their use in the construction of road due to improper handling or their poor quality itself. Delay In Project Due to Weather Phenomena: The project might move out of the scheduled time limit due to the changes in weather phenomena most commonly including delay due to rain.. Dixit.5 RESULTS The following results were found from the tests conducted on increasing the strength and durability of the road in the process of pavement construction: Ø The extension of highway can lead to reduction of time travel by 3 hours. Ø It lead to smooth flow of traffic . Ø Due to the increment in width of highway the accident rate can be reduced by 18%. Dixit.6 Ø Other properties such as tear propagation and resistance of the road can be encourage by using their use and promote research and development on their properties. Dixit.7 CONCLUSIONS A detailed study was carried on the extension of NH 58 and stability of the pavement which was constructed using these materials. In the study it was found that by increasing width of NH58 the time of travelling is reduced by 3hours geo material are the best suited materials for pavement construction. They lead to an increase in the stability of the pavement by strength, by environmental feasibility and endurance to vehicular loads and environmental impacts. Thus, the extension of Highways has been recommended in various states and countries where the population is large and ongoing research is being conducted to improvise the properties and durability of roads and Highways for pavement construction.
Volkswagen Will Launch One New EV Every Month From
Volkswagen's has an ambition to become a global EV giant. This has been known to the world and is nothing new. But now the German brand has revealed its mega-plan to launch a new EV every month from 2022. They has also revealed that they wants to increase their production facilities. A step in this regard is setting up of 16 new electric car production facilities. The brand is keen to launch around 300 different electric-powered models by 2030. Many of the models launched will be the electric variants of the existing models. It’s a very ambitious and well-planned strategy to become a global EV giant. Through this strategy, Volkswagen will be able to launch the bigger fleet of environment-friendly zero-emission cars and it will be a big step in becoming successful as a global EV giant. The first pure electric model from Volkswagen will be launched in 2020. This hatchback will be christened as ID, in line with the concept model. Volkswagen is investing a huge amount of Rs. 1,600 crore in powertrain development. The German auto manufacturer have claimed that its future powertrains will be built in such manner that will comply with the upcoming stringent emission norms. The brand also believes its drive towards zero emission mobility will help the automaker to also meet the new stricter emission norms easily. Volkswagen has its own reason as also the rest of the world automobile market which is thriving towards zero emission pure electric mobility. Not only that the German brand aims to become a global EV giant by 2030, but is also trying to improve its brand image that was severely affected due to the dieselgate scandal. This scandal had led the brand to face numerous lawsuits across the world and also pay hefty fine amounts to the affected customers in several countries. The automaker believes that launching a wide range of zero-emission pure electric vehicles will help the brand to come out of the darkness created by the scandal. During the conference, Müller admitted that Volkswagen’s rapid transformation and focus on EVs has been driven by the diesel scandal. He said: “The diesel scandal told us there was a need for radical change; the crisis has acted as a catalyst.” With this statement the brand has made its intentions clear that they have realised that it is time to change and a small bump in its path will not be ignored in its bid to become a global force in coming years.
Extension Of National Highway 58
The NH 58 is one of the busiest and most travelled highway in northern India. It is only 4 lane highway. Due to which the jams take place. As a result the travelling time from Ghaziabad to MuzzafaeNagar is delayed by 4 hours regularly. So to make the travelling smooth and easier the highway should be made 6 lane highway. Due to which the time of travelling is reduced by 3 hours. The first step to a good construction process is to identity the needs of the transportation in the area and of the road. Teams must thoroughly examine the road and define the project in order to get buyoff from the appropriate officials. Make sure the project selected is going to actually enhance the roads.

Health and Society
SCIENCE AND SOCIETY One of the prominent sayings out on the streets is “A teenager can live for a day without food, not without phone”. And the sad part is that it happens to be true. Today’s fast moving life, competitive structure of society has taken away some of the most important things of life which includes time for oneself, time for loved ones, peace, stillness, silence and also hygiene and healthy diet. Now days, people don’t think about what they eat, when they eat, where they eat and how much they eat. They don’t think about exercising, practically because they don’t have time for it. However, hygiene happens to be the most important part of “life”. This is because; a healthy mind resides in a healthy body. In various researches, it was found that physical problems like obesity and it related problems- high cholesterol, hypertension, diabetes, osteoarthritis and asthma, are more prevalent in the age group of 16-25yrs with the changing times. Moreover, this age group is also exposed to psychological disorders like –anorexia nervosa, bulimia nervosa and binge eating. Food influences almost every aspect of our being. It influences our nails, hair, skin, hormones and bones. The right kind of diet helps us achieve a healthy body. One of the foremost problems among teenagers is by a diet plan they understand, eating less and compulsively exercising. Though this may help in the short period, however in the long period, these symptoms can develop into anorexia nervosa, where the person refuses to eat, exercises compulsively and has a distorted body image. All this is caused by the unhealthy, negligent eating habits that have developed due to the “modernisation” of the society. The facebook, whatsapp, wechat and other “not so important” applications on the new gadgets like phones, tabs, smart watches, are a part of our lives but what we have to understand is that they are “only a part of life” and we should not make them “our life”. Moreover, these things if not used judiciously, can become the obstacles in our goals and self growth. Science is boon for the society, but negligence on our part and overuse of science can be catastrophic for this very society. Eat healthy, think healthy and live healthy

Arab The difficult world
It is not easy to be an Arab these days. If you are old, the place where you live is likely to have changed so much that little seems friendly and familiar. If you are young, years of rote learning in dreary state schools did not prepare you well for this new world. In your own country you have few rights. Travel abroad and they take you for a terrorist. Even your leaders don't count for much in the wider world. Some are big on money, others on bombast, but few are inspiring or visionary. These are gross generalisations, of course. Huge differences persist among 300m-odd Arabic speakers and 22 countries of the Arab League. With oil prices touching record highs, some Arab economies are booming. The gulf between a Darfuri refugee and a Porsche-driving financier in Dubai is as great as between any two people on earth. Yet, to travel through the Arab world right now is to experience a peculiar sameness of spirit. Particularly among people under 30, who make up the vast majority of Arabs, the mood is one of disgruntlement and doubt. Factors that contribute to the gloom include the discombobulating impact of one of the world's fastest population growth rates, failing public-education systems and the resilience of social traditions often ill-suited to the urban lifestyle that is now the Arab norm. But it is politics above all that shapes this generation's discontent. In the world at large, things have not looked good for the Arabs for a long time. The generation that emerged after the second world war came to believe in the inevitability of an Arab renaissance after centuries of domination by Ottoman Turks and European imperialists. Within this scheme of Arab progress, the problem of Palestine stuck out like a troublesome nail. Defeat in the 1967 war with Israel shattered many dreams. Yet, even after Israel's victory Palestine remained a touchstone for Arabs everywhere. Sooner or later, it was felt, justice would be done. That confidence has taken a beating of late. Few Arabs expect the peace initiative George Bush launched in Annapolis last November to achieve anything. And the schism between Hamas and Fatah has shaken underlying assumptions. If the Palestinians cannot unite in their own cause, why should other Arabs help them? And which side to support? For fellow Arabs, as for Palestinians themselves, the clash between a heart that cries "resist" and a head that counsels compromise has seldom been more perplexing. As in Palestine, so in Iraq. In 2003 America's invasion produced all but universal Arab outrage. From afar, Iraqi "resistance" looked both natural and noble. But as Iraq has grown messier, the rights and wrongs have grown harder for Arabs to disentangle. There are few heroes in a cast that includes mass killers from al-Qaeda, brutal Shia militias, criminal gangs, Kurdish separatists and corrupt politicians as well as American occupiers. Elsewhere in the region, it has become harder for thoughtful Arabs to blame the government-inspired slaughter in the Darfur region of Sudan or the stalemate between Lebanon's religious sects on a nefarious American foreign policy. Many Arabs still see Mr Bush's "war on terrorism" as a crusade against Islam. But many also note that al-Qaeda-style jihadism has killed more Muslims, from Morocco to Saudi Arabia to the squalid Palestinian refugee camps of Lebanon, than "infidels".
