Horse-run carts portrayed the streetscape right up until the commencement of the previous century, but the arrival of the vehicle, which Carl Benz and Gottlieb Daimler created separately of one another in the year 1886, instituted a totally fresh combination of needs as compared to those connected with horse-run carts – particularly where the suspension was a concern: it was essential to handle superior pace, without jeopardizing road travelers. Carl Benz and Gottlieb Daimler assumed dissimilar approaches to this issue: while Benz chose the cycle as the initiating point for his Copyright Motor Car and employed a navigating head plus ...

Sulphur Dioxide and Our Planet

Sulphur Dioxide is a colourless pungent gas which is highly soluble in water. Fossil fuels such as coal, petroleum and natural gases contain sulphur. When burnt in motor vehicles, power stations and in other industrial applications, sulphur reacts with oxygen and its compounds in the combustion process to form Sulphur Dioxide. These are the artificial sources of Sulphur Dioxide. Apart from these, Sulphur Dioxide is produced naturally in huge quantities during volcanic eruptions and forest fires. It is the most chemically active compound produced by volcanoes. Apart from natural sources, Sulphur Dioxide is also produced in anthropological activities like ...

Solar Power

There are the following ways of generating electricity using solar radiation: use of photovoltaic systems; hot air power - converters of solar energy into the energy of the air flow directed to the turbine generator; solar thermal energy (using the energy generated by the heating of a surface with its subsequent transformation into electrical energy in the steam generators); solar balloon power plants. Electricity produced by the steam generation in the cylinder of the balloon heated by solar radiation. The problem of extraction and processing of solar energy has long worried about the minds of ...

Abstract

The seawater forms 97% of water of the world, and the icecaps account for 2%. The portion of water available for human consumption is barely 0.5% and that also in aquifers. The widening gap between availability and requirement of potable water especially in the Gulf countries has necessitated newer methods and technologies for production of water suitable for human consumption. This situation in the Gulf region has developed due to non- availability of surface water, high growth of population and urbanization, and water depletion. The present paper takes account of the desalinization of seawater plant established in Abu Dhabi ...

1. Introduction Agriculture and other food products are dried for use. The agriculture grains are dried for future use or production process, in order to dry the agriculture products the sun drying has been used for many years. The sun drying dries the products in a open air condition with the help of hot sun rays. In past centuries the sun drying systems has been used. Most of the industries use mechanized drying instead of sun drying system. The mechanized drying uses boilers and fan to heat and force the air to the required part. The time taken for ...

Sun plays crucial role in the life of the Earth. The entire organic world of our planet is obliged to the Sun for its existence. It is not only the source of light and heat, but also the original source of many other types of energy (oil, coal, water, wind). Since people appeared on the Earth, they began using the sun's energy. According to archaeological data, it is known that housing preference was given to quiet places, closed from the cold winds and open to the sun's rays. Perhaps the earliest known solar system can be considered the ...

Introduction

With people becoming more conscious of the detrimental effects of fossil fuel, the demand for green sources of energy is on a rise. The Sun is the source of all the energy in this world. Even if a small percentage of solar irradiance is collected every day then all the problems related to the scarcity of sufficient energy will be solved. However, it is not very easy to collect and store solar energy in an effective way. Solar Collectors also known as Solar Thermal Collectors are designed to absorb solar energy from solar radiation which is then reduced to heat water ...

[Low flow anaesthesia with isoflurane in the dog]. This article in german compares the safety of high and low flow anesthesia in dogs preparing for surgery. Three groups of animals were divided into two low flow and one high flow groups. Vital signs were kept well controlled during the procedures. Notes the highest decrease in body temperature was in the high flow group, and a particularly cooled gas used for that group may have caused this. At least in the context of dogs, this article seems to treat the question of flow rate and core body temp. as a ...

Introduction

Solar heaters have been popularized in recent years for use in tertiary and residential areas. This has happened mostly in the third world countries. The reason behind this encouragement to use solar heaters is the reduction of cost and improving the performance. This has necessitated the use, and testing of solar heaters to produce hot water. The solar heater is fundamentally made up of tanks that act as solar absorbers ad storage bases for warm water. This is used in glazing to profit the green house effect and the insulating cases. The solar heaters can be made from ordinary ...

The following paper describes the current developments and advances in the use and application of smart packaging technology in food packaging processes. The paper focuses on the application of the technology through various methods of smart food packaging, process designs, equipment used and the current applications. The paper also gives the various applications for the smart food packaging technologies.

Oxygen Absorbers

Oxygen absorbers/scavengers refer to smart packaging technologies that work by absorbing oxygen from foods while reducing oxygen metabolism in the packaged food (Latou et al. 2010). The process is designed to decrease oxidative rancidity and stop any unintended oxidation of ...
