AUTECOLOGY Autecology (Greek, 'auto: self ; "oikos': household and "logos': study or knowledge) 1s an older usage term which refers to roughly the same field of study as population ecology. It is derived from the division of ecology into (a) autecology: the study of individual speccies in relation to environment and (b) syneocology: the study ot groups of organisms in relation to the environment or community ecology. However E.P. Odum (1959) divided synecology into (1) population ecology, (2) community ecology and (3) ecosystem ecology while defined autecology as 'species ecology'. Important features of autecology: 1. Autecology is concerned with the study of the interrelations of individual organisms with the environment. 2. It is experimental and inductive. 3. It deals with easily measured variables such as light, temperature, humidity, salinty, available nutrients etc. which can be easily quantified and subjected to experimental design both in the labor...

After knowing about life, living organisms, biosphere and environment, we wili now Come to ecology. Ecology is the branch of biology that deals with the relations of organisms to one another and to their physical surrounding or environment. It is also the SCientific analysis and study of interactions among organisms and their environment, particularly of the abiotic components. Ecology in an interdisciplinary field that includes biology (botany and zoology), geography, genetics, earth science and environmental science. Definition of Ecology The term 'oekologie' (ecology), coined in 1866 by the German biologist, Ernst Haeckel Was from the Greekk oikos meaning "house or "dwelling", and logos meaning "Science or "study". Thus, ecology is the "study of the house of nature". Haeckel intended it to encompass the study of an animał in relation to both the physical environment and other plants and animals with which it interacted. Haeckel first d...

Human body contains different organs such as heart, lungs, liver, stomach, intestine, eyes, ear, muscles, bones etc. Each of them also perform specific function. But they work in a coordinated or integrated manner for the benefit of the individual. For example, when we write, there is coordination between the eyes and the hand. When somebody is dancing or playing, there is coordination among the functioning of hands, legs, head, eyes & ears etc. As soon as we eat, the digestive glands start secreting enzymes. When somebody runs, the rate of respiration & circulation increase to provide more energy. So integration of activities of different parts of the body or organs is essential for the organism. Such integration is achieved by two systems, nervous and endocrine systemns Nervous system consists of a group of organs which control and coordinate the activities of various parts of the body in response to external and internal changes or stimuli. The basic components of nervous sy...

INTRODUCTION OF ECOLOGY     Before going to read full ecology post, we should know about life and environment. Life originated in our earth around four billion years ago. It is generally agreed that all life forms of today evolved by a common descent from a single primitive life form. It is not known how this early life form came into existence, but scientists think that it was a natural process which took place perhaps 3,900 million years ago. The earliest claimed life forms are tossilized micro-organisms or microfossils. They were found in iron and silica- rich rockS which were once hydrothermal vents in the Nuvvuagittuq greenstone belt of Quebec, Canada, and these rocks are as old as 4.28 billion years. If this is the oldest record of lite on earth, it suggests an almost instaneous emergence of life after oceans were formed 4.4 billion years ago. Moreover a scientific study showed that geological formation of stromatolites of 3.45 billion years old contain fossilized cyanob...

                                    What is SAR? Specific Absorption Rate (SAR)   is the rate at which electromagnetic power radiated from mobile handsets and towers is absorbed by the human body.

                  What is a SAR value?   SAR   Value  is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue. Every mobile phone model is tested for radio wave emissions. Using an internationally standardized method that meets government and regulatory requirements, a measurement is made to determine how much electromagnetic energy is absorbed by body tissue. This gives the SAR (specific absorption rate) value. Governmental and regulatory agencies have established SAR limits under which cell phone use has been determined by them to be safe.

                          What is SAR Limit in India?   The Inter-Ministerial Committee on EMF Radiation set up by the Ministry of Communications and Information Technology had suggested stricter SAR limits (2 watt per kg) for mobile handsets.  While acknowledging the sensitivity of health related effects of radiation emissions from mobile towers and the recent concern raised by World Health Organization, the Indian Government has decided to set the new SAR limits to  1.6 watt per kg.  This would make the Indian standards closer to the US standards prescribed by the  FCC (Federal Communication Commission)  where the permissible SAR levels are set at or below 1.6 watt  per kg taken over a volume containing a mass of 1 gram of tissue.

    How is SAR harmful for Human Body?   A high level of SAR is known to have ill effects on humans.

  SAR For Cell Phones: What It Means For Me?   There is considerable confusion and misunderstanding about the meaning of the maximum reported Specific Absorption Rate (SAR) values for cell phones (and other wireless devices). SAR is a measure of the rate of RF (radiofrequency) energy absorption by the body from the source being measured – in this case, a cell phone.  Many people mistakenly assume that using a cell phone with a lower reported SAR value necessarily decreases a user’s exposure to RF emissions, or is somehow “safer” than using a cell phone with a high SAR value. While SAR values are an important tool in judging the maximum possible exposure to RF energy from a particular model of cell phone, a single SAR value does not provide sufficient information about the amount of RF exposure under typical usage conditions to reliably compare individual cell phone models.

                 So how safe are mobile phones? There is concern at the moment over the use of cellular phones and their possible health implications. All the research is inconclusive so the bottom line is, cellular phones may be a potential health hazard. Different cell-phone models emit different amounts of radiation, so one way to reduce your exposure is to purchase a cell phone with a lower SAR (specific absorption rate), a number that indicates how much radiation is absorbed by the human body when the handset is being used at maximum power. The FCC requires cell phone manufacturers to ensure that their phones comply with these objective limits for safe exposure. Any cell phone at or below these SAR levels (that is, any phone legally sold in India) is a "safe" phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg). 

How could I Find the SAR value for my phone? The SAR rating of each individual phone model is now being displayed on all mobile phone and on its packaging, which will enable users to make informed choices when purchasing a handset.  Sarvalues.com  brings this important information free of charge to all cellular users and also provides useful links to other Websites containing information. The easiest way to ascertain SAR for many cellular phones is via the FCC's links to individual manufacturers' Web sites:  http://www.fcc.gov/cgb/sar/  . On this page you will find links to most manufacturers' Web pages that include SAR information for their phones, along with instructions on how to search each site for SAR information. Important user information:  Features of phone models are sometimes revised or improved during production. This could lead to a situation where the same phone type appears to have different SAR values. If so, please refer to the user guide shippe...

What are the Parameters that can affect SAR? Parameters that can affect SAR include: Types of radio service (cellular, PCS, LMR, WLAN, etc.) Types of modulations (CDMA, GMSK, TDMA, AMPS, etc.) Physical orientation to person (held-to-ear, held-to-face, belt-clip, lap-held, etc.) RF power level (in Watts or mW) Changes to transmitter, antenna (extracted/retracted) or accessories (clips, batteries, etc.)

How can I lower my Exposure to Cell Phone Radiation? The following tips will help you protect yourself from cell phone radiation by enabling you to use your phone in ways that lower your radiation exposure. Use a speakerphone, earpiece or headset to reduce proximity to the head (and thus exposure). While wired earpieces may conduct some energy to the head and wireless earpieces also emit a small amount of RF energy, both wired and wireless earpieces remove the greatest source of RF energy (the cell phone) from proximity to the head and thus can greatly reduce total exposure to the head. Carry your cell phone away from your body—in a purse, briefcase or computer bag—not in your pocket where it is pressed up against you. Increase the distance between wireless devices and your body. Consider texting rather than talking -  but don’t text while you are driving.

Types of Ovules                                          We have now seen different types of ovules on the basis of nucellar features. But ovules in the angiosperms exhibit diversity with respect to their size, degree of ovule curvature, nucellus thickness, integument number and thickness, formation of micropyle, funiculus length, degree of vasculature etc. The most commonly used classification of ovules is based on their orientation and curvature. There are mainly six types of ovules:     Orthotropous or Atropous ovule            i)  The body of the ovule is straight and errect.              ii)  The chalaza and the micropyle remain in one line.             iii)   It is considered as the most primitive ovule.             iv)...

WHAT IS ELECTROCHEMICAL GRADIENT? The  electrochemical gradient  is composed of a chemical force (the  ions ' concentration  gradient ) and an  electrical  force (the effect of the membrane potential on the  ions ' movement). ELECTROCHEMICAL GRADIENT OF ION ACROSS CELL MEMBRANE? An electrochemical gradient is a gradient of electrochemical potential, usually for an ion that can move across a membrane. The gradient consists of two parts, the chemical gradient, or difference in solute concentration across a membrane, and the electrical gradient, or difference in charge across a membrane. When there are unequal concentrations of an ion across a permeable membrane, the ion will move across the membrane from the area of higher concentration to the area of lower concentration through simple diffusion. Ions also carry an electric charge that forms an electric potential across a membrane. If there is an unequal distribution of charges across the membrane, then ...

What is Blood? Blood circulates through the body delivering nutrients and removing waste materials. Blood is made up of red blood cells, white blood cells, and platelets all suspended in plasma. Plasma- About 55% of your blood is made up of plasma. Plasma is a liquid made up of proteins, minerals, dissolved salts, and water. Red Blood Cells- Your body produces two million red blood cells every second. Red blood cells are responsible for carrying oxygen from your lungs to your cells and for carrying carbon dioxide from your cells to your lungs where it is exhaled. White Blood Cells- White blood cells defend the body against attack from foreign organisms, such as bacteria and some viruses and form antibodies that protect the body from future attacks. If the body is invaded by harmful organisms, the production of white blood cells increases dramatically. When a white blood cell encounters a smaller organism, it simply engulfs it. If the invading organism is larger, a number of whi...
