The article, Incidental Haptic Sensations Influence Social Judgments and Decisions, contains three paired experiments that test whether or not primary tactile sensations influence cognitive processing in either aspect-specific ways or metaphor specific-ways (Ackerman et al., 2010). In experiments 1 and 2, researchers hypothesized that variable weight unconsciously affects decision-making (Ackerman et al., 2010).). For experiment 1, the weight of a clipboard affected participants’ evaluation on…

Tablets thickness [13]: Tablets thickness was measured by using Vernier calliper. Five tablets was taken and placed between the two arms of the Vernier calliper. 2. Tablet hardness [14]: The crushing strength of tablets was measured by Pfizer hardness tester. 3. Friability [13, 14]: Roche friabilator was used for testing the friability. Twenty tablets was weighed accurately and placed in the tumbling apparatus that revolves at 25 rpm. After 4 min, the tablets…

Task 2 Non-destructive testing is an analysis technique used to evaluate the properties of a material, component or system without causing damage. Advantages Safety Non-destructive tests are designed to maximize both tester and tested product safety. Most of the test are conducted under strict settings to ensure the safety of the testers, and all tested products remain completely undamaged. Reliability Non-destructive testing comes out with accurate results because of the variety of available…

2.1 Polydimethylsiloxane (PDMS) Polydimethylsiloxane (PDMS) own to a group of polymeric organosilicon compounds that are commonly stated as silicones. PDMS is optically clear, and, in general, non-flammable, non-toxic, and inert. PDMS is viscoelastic, meaning that at long flow times (or high temperatures), it acts like a viscous liquid such as honey. However, at short flow times (or low temperatures), it acts like an elastic solid such as rubber. In other words, PDMS will flow to cover the…

Gastroretentive System of Metformin: Approaches to Effervescent Tablet Sudhanshu K Chakravati1, Javed Khan Pathan1, Sapna Malviya1, Anil Kharia1 Modern Institute of Pharmaceutical Sciences, Indore (MP) ABSTRACT Effervescent tablet generally contains in addition to active ingredients, mixture of acids/acid salts (Citric, Tartaric, Malic acid or any other suitable acid or acid anhydride) and carbonate and hydrogen carbonates (Sodium, Potassium or any other suitable alkali metal carbonate or…

In this essay, I will explain how we can benefit from bonding of atoms of certain elements in our daily life. As I will show in this essay, with the help of understanding the surface chemistry, which is the study of chemical reactions at interfaces (surfaces), different desired affects can be produced by the formation of selected elements such as making improved chemical composition of a surface. Surface chemistry today can be applied to solve various issues and problems including fighting…

and continues to attract minerals as it flows downstream. Another salt free method is to use a resin plated ceramic surface that creates molecular patterns on it. As water flows past the ceramic surface, the magnesium and calcium that cause the hardness continues to attach itself to the surface. As it grows too large and can no longer stay attached, it will break off and flow down with the flow of the water attracting and sticking to more…

The smashers are all members of Gonodactylidac and others species which generally their prey on armored animal such as crabs, snails, bivalves and even their species. Size is not an issue to the smasher for example, Gonodactylids stun and crush hard-shield crabs equal to or larger than themselves (Caldwell, 1975). Capabilities of the smashers are also known to kill another member of their species with a single blow. The smasher actually are opposite of the spearers because the smasher species…

Water Quality Water is essential to human life and the health of the environment. Good water quality is essential for irrigation, drinking and recreation and also sustains ecological processes that support native fish populations, vegetation and bird life. We expect that our water supply will not only be safe, but will taste good, and look crystal clear. Water quality is commonly defined by its physical, chemical, biological and aesthetic (appearance and smell) characteristics. Water quality…

metallic bonds have a simple crystal lattice in solid state and are the weakest primary chemical bonds. Hence the reason to why pure metals are dissolved with other elements such as: carbon for mild steels. Metal alloys have increased strength and hardness. The structure of alloys reduces the space between each ion, so there is less space for delocalized electrons and it improves the chemical bond with each element within the…
