Gomukh known as "Gaumukh" or "Gomukhi", is the terminus or pout of the Gangotri Glacier and the source of the Bhagirathi River, one of the primary headstreams of the Ganges River. The place is situated at a height of 13,200 ft in Uttarkashi district in the state of Uttarakhand, India, it is one of the largest in the Himalayas with an estimated volume of over 27 cubic kilometers. It is a holy Hindu pilgrimage site, along with Gangotri, as well as trekking destination. On 26 July 2016, following heavy rains in Uttarakhand, it was reported that the front end of Gomukh was no more, as a large chunk of the glacier had collapsed and was washed away. In 2013, due to cloud burst in Uttarakhand, huge cracks had emerged on the glacier; the word "Gomukh/Gaumukh" means "Mouth of a Cow." Before the heavy rains in year 2016, the opening of the cave looked like the "Mouth of a Cow." Gomukh is mentioned in the Puranas. It is said there that, searching a lost sheep, a boy reached near a glacier in Gangotri, the snout of which looked like the mouth of a cow, thus it got its name'Gomukh'.

From many holy saints, sadhus, adventure seekers, as well as religious people and adventure seekers went there to worship the place. It is rumored that, if anyone visits Gomukh / Gawmukh with evil intentions or polluted body or mind, his ancestors fall in Burning Hell and that person experiences grave horrors and deep melancholy surrounds him. Gomukh is 18 km from Gangotri in the foot hills of Bhagirathi at a height of 4255m, it is the snout of the Gangotri Glacier. The Bhagirathi river here is pretty speedy. Around the snout, nature presents a wild topography. There are boulders scattered here and there with some pieces of broken snow, along with the hard clayey snow of the glacier; the Gomukh snout is moving backwards. According to the modern research the snout has moved 1 km in just 70 years; the first and foremost thing for Gomukh trek is that you must have permission from District forest officer, Uttarkashi. Only 150 permits are issued per day, permission can be taken via fax also; the trail to Gomukh begins from about 18 km from Gomukh.

It was damaged by rockslides by the 2013 North Indian Floods as was road access to Gangotri. 9 km ahead of Gangotri is the abode of Chir trees. After 3 km of Chirbasa comes the dangerous Gila Pahar, the place well known for its landslides prior to the 2013 destruction of much of the trail here. Here the Bharals, a type of mountain antelope are sometimes seen; the Bharals are found above the altitude of 10,000 ft. Only 4 km from here is Bhujbasa, the only night halting place on the way with buildings. One can stay at the GMVN Bunglow, or at Ram Baba's ashram. After trekking 41/2km from Bhujbasa, one reaches the snout of the Gangotri Glacier. A little before Gomukh, the majestic view of Mt. Shivling welcomes the trekkers to the place. On the trail no horses are allowed, so one must take preparations to walk on foot; the trek to Tapovan and Nandanvan starts from here. The route after'Bhojbasa' can be quite difficult, more so since the 2013 floods. One has to cross a boulder zone to reach the Gomukh snout.

The trek beyond Gomukh is quite difficult. Crossing the glacier & going towards Tapovan has become quite dangerous nowadays. There is no track and one must have a guide and should be prepared to face any type of accident which can be a life-threatening one; the last climb to reach Tapovan is stiff, within 2 km a climb of around 1500 foot and is quite a challenging experience. You may apply for an online permit at with an online permit you would still need to get it verified at the district magistrate uttrakasi office

Le Moucherotte is the easternmost peak of the Vercors Massif, the northern culmination of the long ridge that runs along the eastern edge of the Vercors high plateau, overlooks the city of Grenoble. The mountain is divided between the communes of Saint-Nizier-du-Moucherotte, Lans-en-Vercors and Claix. Similar to the rest of the Vercors range, the Moucherotte is composed of limestone. At the foot of Moucherotte, there are three rocks, known as the Three Maidens, which were used in the resistance during the second world war by the maquis of Saint-Nizier-of-Moucherotte; the southern slopes and ridges of the Moucherotte extend to the Col de l'Arc, with three consecutive secondary peaks, called "la Croix des Ramées", "du Grand Cheval" and "du Pic Saint-Michel". The Moucherotte is home to a variety of fauna, including chamois, mountain sheep, deer; the summit is covered in grass, loosely wooded. There was once a cable car, built by the company Applevage, which connected the village of Saint-Nizier Moucherotte to the summit, where there was a hotel, l'Ermitage.

Following first financial difficulties and vandalism, the hotel closed permanently in the mid-1970s. The uniqueness and outstanding natural beauty of the location attracted the stars of the era, it served as the setting for the filming of some scenes from the movie "La Bride sur le cou", with Brigitte Bardot; the stately hotel and left in ruins, was demolished at the start of the twenty-first century to return the site to its original beauty. At the same time, the derelict gondola station was demolished. Today, there is no trace of its glorious past. During the 1968 Winter Olympics, the ski jumping competition was held on a 90-metre springboard, still in place on the northern foothills of the Moucherotte. However, it has seen no use since the late 1980s. There are several conventional methods of ascent: From the village of Saint-Nizier-du-Moucherotte, either by the Grande Randonnee, or up past the old ski slope. From the bottom of the commune of Saint-Nizier-du-Moucherotte, possible routes are either through the vallon des Forges, or by the east face.

From the Lans-en-Vercors winter-sports stadium, the easiest route utilises a wide track and has a gentle gradient

Navier–Stokes equations

In physics, the Navier–Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of viscous fluid substances. These balance equations arise from applying Isaac Newton's second law to fluid motion, together with the assumption that the stress in the fluid is the sum of a diffusing viscous term and a pressure term—hence describing viscous flow; the main difference between them and the simpler Euler equations for inviscid flow is that Navier–Stokes equations factor in the Froude limit and are not conservation equations, but rather a dissipative system, in the sense that they cannot be put into the quasilinear homogeneous form: y t + A y x = 0. The Navier–Stokes equations are useful because they describe the physics of many phenomena of scientific and engineering interest, they may be used to model the weather, ocean currents, water flow in a pipe and air flow around a wing. The Navier–Stokes equations, in their full and simplified forms, help with the design of aircraft and cars, the study of blood flow, the design of power stations, the analysis of pollution, many other things.

Coupled with Maxwell's equations, they can be used to study magnetohydrodynamics. The Navier–Stokes equations are of great interest in a purely mathematical sense. Despite their wide range of practical uses, it has not yet been proven whether solutions always exist in three dimensions and, if they do exist, whether they are smooth – i.e. they are infinitely differentiable at all points in the domain. These are called the Navier–Stokes existence and smoothness problems; the Clay Mathematics Institute has called this one of the seven most important open problems in mathematics and has offered a US$1 million prize for a solution or a counterexample. The solution of the equations is a flow velocity, it is a vector field - to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in space and at that moment in time. It is studied in three spatial dimensions and one time dimension, although the two dimensional case is useful as a model, higher-dimensional analogues are of both pure and applied mathematical interest.

Once the velocity field is calculated, other quantities of interest such as pressure or temperature may be found using dynamical equations and relations. This is different from what one sees in classical mechanics, where solutions are trajectories of position of a particle or deflection of a continuum. Studying velocity instead of position makes more sense for a fluid. In particular, the streamlines of a vector field, interpreted as flow velocity, are the paths along which a massless fluid particle would travel; these paths are the integral curves whose derivative at each point is equal to the vector field, they can represent visually the behavior of the vector field at a point in time. The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is D u D t = 1 ρ ∇ ⋅ σ + g By setting the Cauchy stress tensor σ to be the sum of a viscosity term τ and a pressure term − p I we arrive at where D D t is the material derivative, defined as ∂ ∂ t + u ⋅ ∇, ρ is the density, u is the flow velocity, ∇ ⋅ is the divergence, p is the pressure, t is time, τ is the deviatoric stress tensor, which has order two, g represents body accelerations acting on the continuum, for example gravity, inertial accelerations, electrostatic accelerations, so on,In this form, it is apparent that in the assumption of an inviscid fluid -no deviatoric stress- Cauchy equations reduce to the Euler equations.

Assuming conservation of mass we can use the mass continuity equation, ∂ ρ ∂ t + ∇ ⋅ = 0 to arrive to the conservation form of the equations of motion. This is written: where ⊗ is the outer product: u ⊗ v = u v T; the left side of the equation describes acceleration, may be composed of time-dependent and convective components. The right side of the equation is in effect a summation of hydrostatic effects, the divergence of deviatoric stress and body forces. All

Kamzík TV Tower

The Kamzík TV Tower is a 196-metre tall television transmission tower in the Koliba area of Bratislava, the capital of Slovakia. The tower sits 437 m above sea level on the Kamzík hill, part of the Little Carpathians, overlooking much of the city; the tower lies within the territory of the Bratislava Forest Park. It was constructed in 1975; the tower was designed by architects Stanislav Májek, Jakub Tomašák, Juraj Kozák, Milan Jurica and Ján Privitzer. The tower has a public observation deck. In conditions of good visibility, Austria and the Czech Republic are visible from the tower; the VEŽA restaurant closed in May 2010 due to a lack of customers. The restaurant's chefs and staff moved to the West Restaurant at the Best Western West Hotel about 100 m down the tower approach road. In 2011, a new restaurant named Altitude opened with an updated interior, serving Mediterranean cuisine; the restaurant is divided into an observation cafe bar, another restaurant, Brasseria, on one floor and the main restaurant on the floor below with rotating tables which provide a 360-degree panoramic view.

Christine Dwyer Hickey

Christine Dwyer Hickey is an Irish novelist, short story writer and playwright. Her writing was described by Madeleine Kingsley of the Jewish Chronicle as "depicting the parts of human nature that are oblique and voiced". Christine Dwyer Hickey was born in Dublin in 1958, she is an only girl of four siblings. After her parents' marriage broke up, her father became the chief carer of a somewhat chaotic family life; when Hickey was ten years old, she went to Mount Sackville Boarding school. She described her years there as a time of creativity, her childhood has informed some of her work Tatty, a story of a marriage breakup from the child’s point of view. It was described in a review published by Independent News & Media as a novel, both "harrowing" and "immensely funny", one that "does not preach about the horrors of alcoholism allows the reader to experience at first hand the confusion and despair the children of alcoholic parents suffer"; as a child she spent much time with her father and went to the races with him.

She used this experience in her 1991 short story, Across the Excellent Grass which won the Powers Gold Short Story Competition at Listowel Writers’ Week. She won the same competition the following year with Bridie’s Wedding and was a prize winner in The Observer/short story competition with Teatro La Fenice; the Dublin Trilogy was published between 1995-2000 as The Dancer, The Gambler and The Gatemaker by Marino Books and was republished by New Island in 2006-07. The trilogy is the story of a Dublin family between the years 1913-1958. Hickey published Tatty in 2004 followed in 2009 by the Last Train from Liguria, set in Italy during the fascist era and 1990s Dublin; the Cold Eye of Heaven was published in the US by Dalkey Archive. A short story collection, The House on Parkgate Street and other Dublin stories was published in 2012 and Snow Angels, a play, was published in 2014 following its run at the Project Arts Theatre. Hickey's novel The Cold Eye of Heaven won the Kerry Group Irish Fiction Award in 2012, was nominated for the 2013 International Dublin Literary Award, shortlisted at the 2011 Irish Book Awards for novel of the year.

Her novels have been nominated for the Orange Prize, the Prix Européen de Littérature, the 50 Best Books of the Decade and the Hughes & Hughes Novel of the Year. Her short stories have won several awards, most the Short Story Award for Back to Bones, longlisted for The EFG Sunday Times Short Story Competition 2017. The Lives of Women was published in 2015 and in the US in 2018. Tatty has been chosen as the Dublin: One City One Book for 2020, she is an elected member of Aosdana, the Irish Academy of ArtsHickey has cited James Joyce and Virginia Woolf as her writing influences. A review in the Irish Times compared her short stories to Joyce's Dubliners, the poet John Montague has likened her work to that of Katherine Mansfield; the Dancer The Gambler The Gatemaker Tatty, The Dublin Trilogy Last Train from Liguria The Cold Eye of Heaven The Lives of Women The Narrow Land The House on Parkgate Street and other Dublin Stories Snowangels Among other awards, Hickey has won or been nominated for: The Dancer: shortlisted for Irish Novel of the Year Tatty: shortlisted for the Irish Novel of the Year Tatty: longlisted for The Orange Prize The Cold Eye of Heaven: winner Kerrygroup Novel of the Year Award The Cold Eye of Heaven: nominated International Dublin Literary Award Back to Bones: longlisted the EFG Sunday Times Short Story Award Back to Bones: winner of Short Story Award Irish Book Awards The Narrow Land: Shortlisted for Irish Novel of the Year
