Muscles can only exert a force and do work by contracting. An example is the antagonistic pair of muscles used in bending

different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction. It is generally accepted that muscle fibre types can be broken

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)‚

Fibre is an important part of a healthy diet. A diet high in fibre has many health benefits. It can help prevent heart disease‚ diabetes‚ weight gain‚ some cancers‚ and it can also improve digestive health. However‚ many people don’t get enough fibre. On average‚ most people in the UK get about 14g of fibre a day. You should aim for at least 18g a day. Fibre is only found in foods that come from plants. Foods such as meat‚ fish and dairy products don’t contain fibre. There are two different types

what makes electrospinning different from other nanofibre fabrication processes is its ability to form various fibre assemblies. This will certainly enhance the performance of products made from nanofibres and allow application specific modifications. It is therefore vital for us to understand the various parameters and processes that allow us to fabricate the desired fibre assemblies. Fibre assemblies that can be

CORE PRACTICAL ONE Describe how the effect of caffeine on heart rate in Daphnia can be investigated practically‚ and discuss whether there are ethical issues in the use of invertebrates. Daphnia‚ the water flea‚ is a small freshwater crustacean which lacks physiological methods of maintaining a constant body temperature. This means that if the environmental temperature changes‚ its body temperature does so too and its metabolic rate will be expected to rise or fall accordingly. So the temperature

Introduction: The awareness of occupational hazards can be traced back to the 18thcentury when Bernadino Ramazzini‚ also known as “The Father of Occupational Medicine”‚ recognized the dynamics of health and disease in relation to occupation (Gambhir et al‚ 2011). Awareness of occupational hazards among dental professionals as well as practicing preventative strategies can provide a balance between maximum benefit and minimum harm to health and well being (Mohammed et al‚ 2013).
