A soil moisture sensor is an integral aspect of the various precise irrigation techniques. This project focuses soil moisture sensor which can be implemented in a large array spreading throughout an irrigated field. Soil conductivity depends on the moisture content around the probes. This is particularly useful for monitoring moisture levels around roots of crops planted in an organized manner. The network architecture allows real time monitoring. A microcontroller is used to scan the array of…

Lemna is a free- floating aquatic plant from the duckweed family, that consists of small, individual thalli (Tkalec et.al, 2001). Lemna are small, fast growing plants and they develop dense mats on ponds, especially when enough light and nutrients are available (Gérard et.al, 2014). Salt is the most toxic substance, as it causes an inhibition of plant growth and a decrease in nutrient uptake (Chang et.al, 2012). Salt stress induces the production of abscisic acid (ABA), a plant stress hormone,…

Imagine a world filled by gases and the only way you could breath is with a mask. You may be thinking, well that only happens in the movies. NO! The carbon dioxide levels are rising at unprecedented rates and scientists believe this could actually happen... The strange part is that most scientists think it is us, the humans causing this problem. For decades now a major political and scientific topic has been climate change. The EPA defines climate change as “any significant change in the…

which are solid, liquid and gas. Snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity are the examples of water occur in nature. There is also water cycle on the earth. The process of water cycle includes evaporation,…

Functions of the skin: There are eight main functions associated with the skin. These are as follows... 1. Secretion – the skin secretes sebum from the sebaceous glands. This fatty substance lubricates the hair shafts and when combined with perspiration on the surface of the skin, it creates a natural moisturiser which acts as a protective barrier against bacteria. 2. Heat regulation – body temperature is maintained in healthy humans at 37oC (98.6oF). organs involved in heat production are…

Located on the Indonesian island of Sumbawa, Mount Tambora is in the province of West Nusa Tenggara. The eruption of Mount Tambora on April 10, 1815 marked the most powerful eruption of a volcano in the past 500 years thats has struck Indonesia. The creation and eruption of Mount Tambora can be contributed to the interaction between the Indo-Australian and Eurasian plate. The plate with higher density subducts under the plate with lower density. As the plate goes under, it melts and forms a…

developments due to the rising sea level; therefore, millions of people would be affected. In addition to increased sea levels, riverbanks could rise as well, expanding the potential for floods. The warming of the Earth would also increase the rate of evaporation, affecting the amount of freshwater readily available. This will lead to larger disputes over available freshwater in places it’s scarce. The environmental impacts due to an average global temperature increase have possible cataclysmic…

with an average elevation of 985 feet; this is one of the primary reasons that the annual rainfall is thinly dispersed and scattered – approximately 16.5 inches. On top of that, 40% of the surface gets less than 10 inches per year, with annual evaporation exceeding annual rainfall on more than three fourth of the land. Hence, Australia is generally warmer than the United States. (All figures from the paragraph above can be found in Country Report). Australia has a total area of 2,988,885 Square…

The anti-aging product I am researching is the Murad Age Renewal Serum.

Water is one of the most important and essential fluid to our human body. We use and drink water almost 24 hours a day and 365 days a year, however, many of us probably have never thought of and find out what are the chemical and scientific reasons behind the importance of water. Approximately 50-65% of the average adult human body is water, however, this varies based on a number of factors such as age, health, weight and sex. In males, it is normally about 60% of the body weight. In…
