Ergonomic Science Of Work Physiology & Work Demands

Work physiology is the science that studies how the human body responds to the physical stress of work or activity demands. These physiological responses are important in maintaining homeostasis in the body during work activities and reducing the adverse effects of physiological fatigue due to work. Homeostasis is defined as the maintenance of a constant or changing environment. In practical terms, it refers to the relatively constant internal environment of the human body during both stressed and relaxed conditions, due to many regulating anatomical and physiological systems. These organ systems and physiological responses regulate cellular metabolism, energy production, cellular waste product removal, voluntary muscle control, and the flow of blood and oxygen to working muscles. An understanding of the role of major organ systems in the human body during work activities and the relationships between work intensity and recovery intervals is essential to the science of ergonomics.

Metabolism
To accomplish work, the body requires energy, oxygen and nutrients. The human body consumes and uses carbohydrate, fat and protein nutrients to provide the required energy to maintain homeostasis both at rest and during work activity. During work, the primary nutrients utilized are fats and carbohydrates, with proteins contributing less than 5-15% of the total energy used. These nutrients, after having been converted to chemicals, enter the blood stream and circulate to the various internal organs and muscles. At the muscle sites, this chemical energy is converted into mechanical energy, or a muscle contraction, and heat. This process is known as metabolism.

Working muscle requires a constant supply of energy. The fundamental source of energy for these contractions is the high-energy Adenosine Triphosphate (ATP) molecule. The ATP molecule is the most important energy carrying molecule in the muscle cell. The ATP compound consists of three parts: adenosine molecule, a ribose molecule and three phosphate molecules linked together by chemical bonds. The bonds linking the phosphate molecules are high-energy bonds and when these bonds are broken, large amounts of energy are released. This energy is then used for muscle contractions. The energy can be liberated from the ATP molecule by a process known as phosphorylation. This metabolic process is shown below. Phosphorylation is the process in which the Adenosine Triphosphate molecule is broken down by the enzyme ATPase into Adenosine Diphosphate (ADP), a phosphate molecule (Pi) and energy.
Aerobic Metabolism
The Adenosine Triphosphate needed for muscle work can be produced from either aerobic (with oxygen) metabolism or from anaerobic (without oxygen) metabolism. The aerobic metabolism of nutrients refers to the oxidation of glucose or glycogen molecules and fatty acids to form ATP, this process is called aerobic glycolysis. This metabolic pathway requires a continuous supply of blood in order to provide ongoing oxygen and nutrients.

Economic City To Transform Medak District

Medak District is located in Andhra Pradesh, India. Sangareddy is the district headquarters of Medak. Minister for Major Industries J. Geeta Reddy recently claimed that the Medak district has witnessed multi-fold development. The Export Promotion Industrial Park in Medak District has an area of 300 acres, and the Garment Complex at Gundla Pochampally in Medak District has an area of 170 acres. The Nagarjuna Agricultural Reserach and Development Institute (NARDI) has a 107-acre research farm, situated at Wargal, Medak District, 50 km from Hyderabad on the Rajiv Gandhi Highway.

The proposal of Hyderabad Economic City (HEC) will transform Medak considerably. Ras Al Khaima Authority (RAKIA), and APIIC signed a memorandum of understanding in September last for the development of HEC with a proposed investment of Rs 20,000 crore. The Andhra Pradesh government recently allotted 471 acres of land at Sultanpur village of Medak district for the first phase of Hyderabad Economic city which is being jointly developed by APIIC and RAS-AL-KHAIMAH. RAK is the investment arm of the UAE government which had asked for a total of 2000 acres for the project. The balance land would be allotted in due course according to an APIIC official. It would be an integrated financial hub with infrastructure facilities for financial services operations for banking, insurance and asset management companies. The project would also have an integrated health city that would include facilities for clinical and non-clinical services, hospitals, and medical colleges, research services for clinical trials, drug delivery system, stem cell research and genetic research among other things, according to sources. This is the largest real estate and infrastructure project coming up in Andhra Pradesh and is expected to provide quality employment to thousands of people. RAKIA is a world renowned and much respected investment body that is cash rich. Executing a project of this magnitude is well within their capability. Residential areas adjacent to Sultanpur such as Ayilapur, Kistareddypet and patelgudem will be the most sought after destinations and are likely to appreciate in value considerably.

This project is a boon to Medak district which would assume great significance in terms of the infrastructure being provided and tremendous employment potential. Sultanpur is located abutting the outer ring road and is presently accessible from the Mumbai highway via the Beeramguda crossing which is two Km after BHEL. A three and half Km drive would bring you to Kistareddypet village. The limits of Sultanpur commence barely half a Km to the right of Kistareddypet which has already been witnessing real estate development in the form of gated communities, residential layouts and apartment complexes. Sultanpur is situated at a distance of 16 to 18 Km from important hubs such as hi-tech city area, Microsoft campus, financial district etc. The prestigious IIT Hyderabad campus is also coming up in Medak district around 20 Kms from Sultanpur.

You dont have to suffer through sleeping in sauna-like temperatures. There are things that both you and your air conditioning company can do to fix this.

How much are your windows contributing to the heat in your room? Old, inefficient windows let heat right in (or cold air right out). If your windows arent sealed properly or dressed with sun blocking curtains and blinds, youll notice a dramatic temperature difference between your room and rooms that are mindful of their windows.

Are your air ducts properly sized and sealed? Air ducts are responsible for transporting cool, conditioned air to each room in the house. If there is a major tear or leak in your air ducts, one or more rooms may lose their cold air to the attic. A few easy signs that you have an air duct leak are:
