Communication for Sustainable Agriculture Production
1. IntroductionThe green, white and blue revolutions gave us food security. The high yielding varieties and new technologies were webbed with chemical farming. Even today we have critical gaps existing in production of food through technology use and at traditional farmer’s field. The chemical farming resulted in the soil degradation, water pollution, soil erosions and soil salinity .By now we face land degradation problems in 173 million hectares which is around 53% of cultivated land. Annually we loose 5000 Million Tones of top soil with NPK losses of 5-8 Million Tones per year. In Mahrastra a survey showed that the depth of black soil was 60 cms in 1910 which has reduced now. About 18% of it has turned as shallow land. Reduced soil depth has resulted into low productivity, increases soil runoffs and drought like conditions. Therefore to avoid these ill effects we have to link strong information and Read more…
Chandrayaan-1, India’s First Mission to Moon
It was a tremendous achievement in Indian space research programme soon after historic launching of Chndrayaan-1 to the orbit of the Moon. Once again India has proved that India is one of the advanced countries as concern to the space borne technology in the world. This achievement came to harness the goal of success due to some important relevant India’s space organizations which are mainly of Indian Space Research Organization (ISRO), Space Application Centre (SAC), National Remote Sensing Agency (NRSA), and Indian Institute of Remote Sensing (IIRS), National Physical laboratory (NPL), Defense Research and Development Organization (DRDO) etc. India is also very advanced in techniques of space borne application due to availability and dissemination of good digital satellite data. There are good resolution of satellite data derived from sensors like LISS-III, LISS IV and Panchromatic camera in the visible and Near Infra Red band of EMR spectrum which are the Read more…
Shoreline Change Monitoring in Tuticorin Coast – India, Using Remote Sensing and Gis Tools
IntroductionShoreline or coastline, the boundary between land and sea keeps changing its shape and position continuously due to dynamic environmental conditions. The change in shoreline is mainly associated with waves, tides, winds, periodic storms, sealevel change, the geomorphic processes of erosion and accretion and human activities. Shoreline also depicts the recent formations and destructions that have happened along the shore. Waves change the coastline morphology and forms the distinctive coastal landforms. The loose granular sediments continuously respond to the ever-changing waves and currents. The beach profile is important, in that it can be viewed as an effective natural mechanism, which causes waves to break and dissipate their energy. When breakwaters are constructed, they upset the natural equilibrium between the sources of beach sediment and the littoral drift pattern. In response, shoreline changes its configuration in attempt to reach a new equilibrium (Ramesh and Ramachandran 2001). Monitoring changes in shoreline helps Read more…
Hyperspectral Data Processing and Applications
The availability of hyperspectral data has overcome the constraints and limitations of low spectral and spatial resolution imagery, and discreet spectral signatures. Hyperspectral images provide high spectral resolution data, with many narrow con¬tiguous spectral bands allowing for detailed applications.1. Target detection, 2. Material mapping, 3. Material identification, 4. Mapping details of surface propertiesIn these cases, the additional information provided by hyperspectral imagery often provides results not possible with multispectral or other types of imagery. In target detection projects, investigators are generally trying to locate known target materials. This can sometimes involve distinguishing targets from very similar backgrounds, or locating examples of targets that are smaller than the nominal pixel size. For example, hyperspectral imagery has been used by military personnel to detect military vehicles under partial vegetation canopy, and to detect small military objects within relatively larger pixels.The spectral characteristics of oil seeps and oil-impacted soils are generally too subtle Read more…
Top 8 Reasons Why the Sixth Sense is the Key to Enlightenment
When you think of the great enlightened masters, they all seem to share many similar traits: Unusually intelligent, charismatic, can do miraculous things, and they all exhibited the use of the Psychic Sense.The Psychic Sense or Sixth Sense is anything that excels beyond ‘basic’ sensory.* So a dog that can always sense when its owner is coming home,* Waking up in the middle of the night and feeling something is ‘strange’,* Or you and a friend laughing about how you were both thinking of Blue Oyster Cult, are all examples of the Sixth Sense in use.Let me make clear that the Sixth Sense is natural and scientific, not mystical and unexplainable. It’s your body’s ability to pick up on fine energies, or ‘wavelengths’, that have yet to be detectable by today’s crude electronic instruments -and yet, the body, being a sensitive supercomputer, can.And because it’s a bodily sense, like any Read more…
Zayiflamak Icin Gi Diyeti- Prof Dr Metin Ozata
ZAYIFLAMAK ICIN GI DIYETI YAPINIZGlisemik indeks kavrami ilk defa Kanadali Profesor Dr. David Jenkins tarafindan 1980’li yillarda ortaya konmustur. Bir gidanin veya karbonhidratin glisemik indeksi onun kan sekerini yukseltme ozelligidir. Glisemik indeks 0 ile 100 arasinda degisir. Glukozun degeri 100 kabul edilerek diger karbonhidratlarin kan sekerini yukseltme gucu veya etkisi siralanir. Glisemik indeksi yuksek gidalar kan sekerini cok hizli yukseltir ve bu nedenle kilo yapar. Eger glisemik indeks dusukse, o gida, kan sekerini yavas ve daha az yukseltir. Bu tur gidalar ise zayiflamak icin cok faydalidir. Protein ve yaglar icin glisemik indeks soz konusu degildir. Kan sekerini cok yukselten karbonhidratlara yuksek glisemik indeksli, az yukseltenlere dusuk glisemik indeksli karbonhidratlar denir. Yuksek glisemik indeksli karbonhidratlar kan sekerini cok arttirdigi gibi insulin hormonunu da cok yukseltirler. Karbonhidratlarla birlikte yenen protein ve yag da o karbonhidratin kan sekerini yukseltmesine katkida bulunabilir.Zayiflamak isteyen kisilerin glisemik indeksi dusuk gidalarla beslenmesi gerekir. Glisemik indeksi (seker yuku) yuksek olan Read more…

The Humble TV Remote Control: Friend Or Foe?
Technology such as LCD Monitors covered in this article are rapidly changing our world in many ways and becoming more affordable for the average person. It’s worth mentioning however that better technology is actually properly defined as simply a better way of doing something we already do with whatever process we have at hand. Rather than thinking of better technology in terms of computers, hi tech gadgets and such, for example anytime we find a way to get to work 5mins faster than before we have found a better technology to improve our lives in some respect.Several people in families all over the world fight over many things. I am not referring to things like domestic violence here, which are despicable acts of cowardly people. I am referring to things like food, cleanliness, newspaper subscriptions and the like. I’ve personally witnessed otherwise peaceful families break into literal wars over mundane Read more…
