You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better.
Indian artists employed multiple perspectives unlike their European counterparts in their paintings. The idea was to convey reality that existed beyond specific vantage point. Some of the special Miniature paintings include illustrated manuscripts of Jains and Buddhists, the flowering of the Mughal, Rajput and Deccan miniatures. Themes used were from Indian epics like Ramayana, Mahabharata, Bhagvata Purana, Rasikpriya, Rasamanjiri as well as ragas of Indian classical music, etc.
We use two eyes to read and the part of our brain that develops our language and auditory processes is on the opposite side to where our visual perception develops. We need visual perception to recognise the written letters and auditory processing to convert them to the sounds and words they represent. Therefore, we need good communication between both sides of the brain; this is bilateral integration. Children begin to develop bilateral integration through movement and playing in their environment with different objects and obstacles.

Alkyd is an old interior paint made newly popular by a change in solvent - a super-refined petroleum chemical that has almost no odor. It is not a water paint. You thin it and clean brushes with mineral spirits or turpentine, or, if you want to retain the odorless feature, with the new odorless solvent. (Ask the paint-store man for just that, odorless solvent).
Technical advancements are constantly being made to improve the life span, durability, wear and performance of exterior paints. The Akrylatfarg range at Ray Munn, for example, is an environmentally sound water-based option.
Football helmets have changed dramatically with the modernization of the sport to facilitate technological changes and to improve the safety of the game. Despite lower rates of some injuries, serious traumas to the head are still common, and determining the consequences of these traumas is an active area of research. In addition to the acute concern about traumatic brain injuries, such as concussions, studies have found players increase their risk for long-term problems such as chronic traumatic encephalopathy (CTE). Football helmets present a unique design challenge because, unlike bicycle helmets, which are thrown out after a single hit, football helmets need to withstand multiple impacts.
