Ionospheric Effects of Total Solar Eclipse on 22 July, 2009 Observed Over Crest of EIA, Bhopal
A solar eclipse provides us with a rare opportunity to study the ionospheric effects associated with an accurately estimated variation of solar radiation during the eclipse period. An exceptionally long total solar eclipse occurred on Wednesday, 22 July 2009, that traversed the eastern hemisphere in a narrow corridor. The Ionosonde observations taken at Space Science Laboratory, Department of Physics and Electronics, Barkatullah University, Bhopal during the three days centered on the total solar eclipse of 22 July 2009 are described. The eclipse was sufficient to decrease the ionization of some regions of ionosphere by the solar disc which was obscured at the maximum phase. The effects on the ionospheric parameters are observed when eclipse reached its maximum totality. A magnetic disturbance occurred during the period of the observation. Therefore the Ionosonde observations are discussed in conjugation with the changes which occurred in the earth’s magnetic field and the ionosphere during the event of the eclipse.

Implementation of LSB Steganography Technique on FPGA for Highly Secured Image
Steganography is skill of hiding secret messages or hiding secret images so that only the writer and the intended recipient are aware from hidden information .Steganography is an powerful technique in terms of any type of carrier which is hiding technique that develops stimulating structures to fruitfully & successfully hide information (may be a text or an image ) in color images. Digital steganography is basically about hiding a file in, or adding a file to, another file, called the carrier file, such that the carrier file is not changed enough to raise suspicion that something may be concealed within it or appended to it. The steganography scheme on hardware platform shows huge potential by means of various advantages such as high speed implanting, specific hardware dependency, and low power consumption etc. Current developments favor using digital images, carrier files as the cover file to hide another file that contains the secret information in the form of either text or image that means carrier file. Hardware stenographic modules applied in a processor platform like FPGA which offer some essential additions to the existing benefits of software based stego systems. It also offers the Embedding rate which is very high when compared to the systems in software domain. LSB method representing a high imbedding capacity.

On Bridging the Gap in the Sexual Behavior of the Sexes: The Mediating Role of Culture/Environment
Sexuality is an important component of human life given its implication for sexual satisfaction, reproduction, egalitarianism and the continuity of the human race. The purpose of this paper is to present a review of the literature on cultural sex-role prescriptions for male control and female deference particularly in the Nigerian literature, and to demonstrate the implication of such for relationship satisfaction, sexually transmitted diseases and egalitarianism. In this article, we emphasize the socio-cultural specifics of the Nigerian society and its role in perpetuating power imbalance, sexual inequality and sexual in-expression between men and women.

Ebola Virus- A Deadly Virus its Causes, Symptoms, Prevention and Treatment
Ebola is a deadly disease caused by a virus. There are five strain, and four of them can make people sick. After entering the body, it kills cells, making some of them explode. It wrecks the immune system, causes heavy bleeding inside the body, and damages almost every organ. The virus is scary, but it also rare. You can get it only from direct contact with infected persons body fluids. The on-going Ebola outbreak in the West African countries is so far the worst in the history of the deadly disease. The virus seems to have gripped the world's interest due to its destructive potential, claiming nearly 7000 lives in Sierra Leone, Liberia and Guinea -- worst-hit Ebola nations in West Africa. Although a few cases of Ebola have been reported from Australia, America and other nations of the world, no positive cases of Ebola virus in India have been reported till date. According to the WHO reports, on an average, 80% of the people infected with this virus do die. Their death is usually due to a drop in their blood pressure and failure of organs.

Investigation the Effect of Conservation Tillage on Soil Organic Matter (SOM) and Soil Organic Carbon (SOC) (The Review)
Pores and organic matter take a multitude of forms in soil and their characteristics change in space and time following a change in tillage practices as a new “steady state” is approached. Information on the variation with depth (stratification) in the characteristics of pores and organic matter and the rates of changes in these characteristics are vital to interpreting the short- and long-term impacts of the reduction of using conventional tillage on the productivity and hydrology of agricultural soils. This information is also of value in estimating the effect of a reduction in tillage on the sequestration of carbon in agricultural soils. The influence of tillage on bulk density, macro porosity and organic matter content was found to be documented more extensively than the effects on pore size distribution, soil organic matter fractions and their interactions at different soil depths. Many of the reports documenting tillage-induced changes in soil porosity and organic matter were based on measurements at a specific time after initiating the tillage trial. The potential advantages of conservation tillage in organic farming are reduced erosion, greater macro porosity in the soil surface due to larger number of earthworms, more microbial activity and carbon storage, less run-off and leaching of nutrients, reduced fuel use and faster tillage. Conversion from conventional (CT) to no-tillage (NT) resulted in an immediate change in the placement of aboveground crop residue and the reduced fragmentation of the soil matrix may also slow the mineralization of SOC.

The Effect of Conservation Tillage on Crop Yield Production
Conservation tillage (CA) systems are gaining increased attention as a way to reduce the water footprint of crops by improving soil water infiltration, increasing soil moisture and reducing runoff and water contamination. The concept of water footprint is defined as the total volume of freshwater used, directly or indirectly, to produce a product or process including the total amount of water required in agriculture for growing crops. About 141 million and 645 thousand hectares of land in the world have been destroyed by erosion because of inappropriate tillage operations. The total amount of 26 billion tons of soil eroded is estimated and about 2 billion tons comes out from Iran. Parallel to the erosion, loss of soil organic matter that occurs on to several factors, farming has become more challenging. Many strategies exist to combat soil degradation through erosion and compaction on agricultural fields. One of these strategies is conservation agriculture (CA). Reduced or no-tillage techniques, together with crop residue management and crop rotation are the pillars of CA. The term reduced tillage covers a range of tillage practices but it never involves inverting the soil. In this way, soil disturbance is minimized and crop residues are left on the soil. Studies in many European countries have shown that CA can indeed be very effective in combating soil erosion. However, soil and water conservation do not appear as main drivers in farmers’ decisions to shift or not to CA. Economic factors tend to be more important, but there are a lot of uncertainties on this domain. Studies show that production costs are mostly reduced, mainly by reduced fuel costs. Although many European studies have investigated the effect of reduced soil tillage on crop yields, a lot of uncertainties still exist.
