landlocked. Nevertheless‚ the lack of unhindered access to the sea adds transport costs and time to international trade transactions. In addition‚ landlocked countries face greater transport risks and hazards than countries which have direct access to international sea routes. The United Nations has addressed the specific concerns of landlocked countries in a number of documents. Among those which are directly related to transport are the following: General Assembly resolution 50/97 of 20 December

Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable

Lipids and Phospholipids The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The

Urban Transport in Indian Cities A peak of rush hour commuters at Churchgate‚ a terminus for one of Mumbai’s main suburban train lines contributing to the nearly 6.5 million people feeding in and out of the city daily. Urban travel in Indian cities predominantly happens through walking‚ cycling and public transport‚ including intermediate public transport (IPT). Despite high growth rates of motorised two wheelers and cars in the last two decades (15 per cent and 10 per cent per annum respectively)

Productivity After two quarters of increasing levels of production‚ the CEO of Canadian Fabrication & Design was upset to learn that‚ during this time of expansion‚ productivity of the newly hired sheet metal workers declined with each new worker hired. Believing that the new workers were either lazy or inefficiently supervised (or possibly both)‚ the CEO instructed the shop foreman to "crack down" on the new workers to bring their productivity levels up. ◦ Explain carefully in terms of production

Kinder transport The killing of children was supported was by the Nazis during the Holocaust. Children were helpless and could not always fight for their survival. With this 1.5 million children were killed by the Germans. Countries wanted to help these children‚ Jewish and non- Jewish‚ for their fate. These children’s fate was categorized in many ways. Some of these ways were; as they arrived in killing centers‚ after birth‚ those who survived because prisoners hid them‚ kids over twelve who
