Wooden ladders are sturdier than fiberglass or aluminum ladders and can be used when heavy loads must be moved up or down the ladder. Aluminum ladders are corrosion-resistant and can be used where ladders might be exposed to weather. They are light weight and can be moved easily for different locations. You should never use aluminum ladders around electrical hazards‚ such as energized electrical conductors or

COOLING TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units

silvery grey metal. Vanadium was discovered by Andrés Manuel del Río‚ a Spanish-born Mexican mineralogist‚ in 1801 [1]. Some sources say Vanadium is soft because it is ductile [1]. Vanadium is harder than most metals and steels [1] It is resistant to corrosion and it is stable against alkalis‚ sulfuric and hydrochloric acids[1]. It is oxidized in air at about 933 K (660 °C‚ 1220 °F) [1]. This paper will discuss the effects of Vanadium on the environment and Vanadium’s properties. Chemical Properties:

Introduction of Ceramics What is Ceramics? A ceramic is an inorganic‚ non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure‚ or may be amorphous (e.g.‚ a glass). Because most common ceramics are crystalline‚ the definition of ceramic is often restricted to inorganic crystalline materials‚ as opposed to the non-crystalline glasses. The word ceramic comes from the Greek word "κεραμικός" (keramikos)‚
