  • VISCOSITY of a GAS -Dr S P Singh Department of Chemistry, a N College, Patna
    Lecture Note on VISCOSITY OF A GAS -Dr S P Singh Department of Chemistry, A N College, Patna A sketchy summary of the main points Viscosity of gases, relation between mean free path and coefficient of viscosity, temperature and pressure dependence of viscosity, calculation of collision diameter from the coefficient of viscosity Viscosity is the property of a fluid which implies resistance to flow. Viscosity arises from jump of molecules from one layer to another in case of a gas. There is a transfer of momentum of molecules from faster layer to slower layer or vice-versa. Let us consider a gas having laminar flow over a horizontal surface OX with a velocity smaller than the thermal velocity of the molecule. The velocity of the gaseous layer in contact with the surface is zero which goes on increasing upon increasing the distance from OX towards OY (the direction perpendicular to OX) at a uniform rate . Suppose a layer ‘B’ of the gas is at a certain distance from the fixed surface OX having velocity ‘v’. Two layers ‘A’ and ‘C’ above and below are taken into consideration at a distance ‘l’ (mean free path of the gaseous molecules) so that the molecules moving vertically up and down can’t collide while moving between the two layers. Thus, the velocity of a gas in the layer ‘A’ ---------- (i) = + Likely, the velocity of the gas in the layer ‘C’ ---------- (ii) The gaseous molecules are moving in all directions due= to −thermal velocity; therefore, it may be supposed that of the gaseous molecules are moving along the three Cartesian coordinates each.

  • 1 Backgrounder About ICLEI, UN Agenda 21 and Sustainable
    Backgrounder about ICLEI, UN Agenda 21 and Sustainable Development By Sue Forde 8/15/2011 In this regard, there are 4 basic terms you need to know: (1) ICLEI (3) Sustainable Development (2) Agenda 21 (4) The Wildlands Project What is ICLEI and why is it bad? ICLEI is the acronym for International Council for Local Environmental Initiatives. The name was changed to ICLEI - Local Governments for Sustainability. ICLEI was set up to promote UN Agenda 21 in local communities. There are already over 600 cities and counties in the US that have signed on and are dues-paying members of ICLEI, including Clallam County and the City of Sequim. The mantra is “think globally, act locally”. (As people are becoming aware of the dangers this presents to our freedoms, they are pressing their elected officials to withdraw – and so far, 8 counties/cities have done so, with many more in the works.) ICLEI is governed by the ICLEI “global charter”. This Charter calls for the “World Organization of United Cities and Local Governments”. One of its goals is to build and serve a worldwide movement of local government to achieve tangible improvements in global sustainability with special focus on environmental conditions through cumulative local actions. Harvey Ruvin, Vice Chairman, ICLEI. The Wildlands Project, said “Individual rights will have to take a back seat to the collective.” (You can’t get more communist than using the word ‘collective’ in a sentence. This is in direct conflict with our US Constitution and State Constitution, both of which are established to “protect and maintain individual rights.” It is also in direct conflict with the sovereignty of our nation.

    Admirable trees estate of versailles estate With Patronage of maison rémy martin The history of France from tree to tree Established in 1724 and granted Royal Approval in 1738 by Louis XV, Trees have so many stories to tell, hidden away in their shadows. At Maison Rémy Martin shares with the Palace of Versailles an absolute Versailles, these stories combine into a veritable epic, considering respect of time, a spirit of openness and innovation, a willingness to that some of its trees have, from the tips of their leafy crowns, seen pass on its exceptional knowledge and respect for the environment the kings of France come and go, observed the Revolution, lived – all of which are values that connect it to the Admirable Trees of through two World Wars and witnessed the nation’s greatest dramas Versailles. and most joyous celebrations. Strolling from tree to tree is like walking through part of the history of France, encompassing the influence of Louis XIV, the experi- ments of Louis XV, the passion for hunting of Louis XVI, as well as the great maritime expeditions and the antics of Marie-Antoinette. It also calls to mind the unending renewal of these fragile giants, which can be toppled by a strong gust and need many years to grow back again. Pedunculate oak, Trianon forecourts; planted during the reign of Louis XIV, in 1668, this oak is the doyen of the trees on the Estate of Versailles 1 2 From the French-style gardens in front of the Palace to the English garden at Trianon, the Estate of Versailles is dotted with extraordi- nary trees.

  • ICLEI Launches Daring Cities 2020
    MEDIA RELEASE ICLEI launches Daring Cities 2020 - the world’s first and largest online gathering on climate change for urban leaders New action-oriented virtual forum will gather and showcase urban leaders taking bold and swift action to tackle the climate emergency in the time of Covid-19. Bonn, Germany (16 September 2020) - ICLEI – Local Governments for Sustainability (known as "ICLEI") is organizing Daring Cities 2020, an action-oriented forum aimed at tackling the current climate emergency by showcasing ambitious local action. Daring Cities 2020 will run from 7-28 October 2020, offering an online array of high level and visionary speaking sessions, a series of informative workshops and personal networking opportunities. The event will help to set the course to COP26 (the 2021 United Nations Climate Change Conference), Daring Cities 2021 and beyond. Even as the COVID-19 pandemic rages on, the climate crisis continues to impact cities, towns and regions around the world. While national and international leaders are struggling to address the threat of climate change, citizens and local leaders are mobilizing to disrupt it. Designed by ICLEI and the city of Bonn, Daring Cities empowers urban leaders - such as mayors, city councilors, administrators, and urban thought leaders, as well as researchers, technical staff, business leaders, civil society decision-makers, community organizers and national government representatives - to tackle the climate crisis. Throughout three weeks the forum will showcase and catalyze exemplary local climate action, including ambitious resilience-building and climate mitigation efforts. "As Mayors, we witness the impacts of climate change in our own cities. We are driven by scientific evidence and our citizens mobilizing in the streets, while many of our national governments still struggle to raise ambition.

  • U20 Rome-Milan 2021 – Urban 20 Calls on G20 To
    TRADUZIONE ITALIANA DI CORTESIA Guidati dalle città co-presidenti di Roma e Milano, noi, i sindaci e governatori delle città sottoscritte, riuniti come Urban 20 (U20), invitiamo i Leader del G20 a collaborare con le città per realizzare società incentrate sull’uomo, eque, a emissioni zero, a prova di cambiamenti climatici, inclusive e prospere. La natura trasformativa dell'Agenda 2030 offre alle città un'opportunità chiave per promuovere un nuovo paradigma di sviluppo sostenibile e avviarsi verso una ripresa resiliente dalla crisi umanitaria causata dal COVID-19. Sindaci e governatori sono in prima linea nella risposta alla pandemia da COVID-19 e all'emergenza climatica. Il modo in cui i leader indirizzeranno i finanziamenti per la ripresa da COVID-19 rappresenta la sfida più significativa per qualsiasi governo impegnato nella risposta a pandemia ed emergenza climatica. La pandemia da COVID-19 ha messo in luce la solidarietà tra città e ha sottolineato l'importanza di lavorare insieme a soluzioni locali che garantiscano che nessuno e nessun luogo vengano dimenticati. Ha sottolineato che istituzioni pubbliche forti e la fornitura di servizi sono vitali per la coesione delle nostre comunità e per garantire l'accesso universale all'assistenza sanitaria in maniera equa per tutti. Per garantire che la fornitura di servizi pubblici a livello locale venga mantenuta, che le persone siano protette e che si realizzi una ripresa verde, giusta e sostenibile dalla pandemia da COVID- 19, le città devono avere accesso diretto a forniture e finanziamenti da fonti internazionali e nazionali, per esempio dai recovery plan nazionali. L'accesso equo ai vaccini deve essere garantito a tutti, in particolare alle città dei paesi in via di sviluppo.
