A proposed algorithm for circle detection using prewitt edge detection technique

This paper presents method to detect and accurately locate circle objects in digital image. The propose method consists of two steps. In first step the edge pixels are extracted using Prewitt edge detection algorithm and then a noise removal process is run to remove the non-circle edge points. The second step, Circle Hough Transform (CHT) is applied to detect circle from the digital image.

Bioassay guided characterisation of endomycophytes from Barringtonia acutangula L. leaves

Medicinal plants have been considered as a host of fungal endophytes with novel metabolites of pharmaceutical importance. Most endophytic fungi that live in higher plants are capable of producing secondary metabolites which are medicinally significant components whose activity against pathogens have been studied previously. Hence an effort was taken to isolate endophytic fungi from leaves of Barringtonia acutangula commonly called the Indian oak or Samudraphal, an evergreen tree with medicinal properties.

Distribution of ABO and Rh(D) blood groups among the people of Mao Naga tribe of Mao, Senapati district of Manipur, north east India

The Genetic studies relating to blood group on populations in north-east India particularly in Manipur have been performed less frequently than in the other parts of India, though there are diverse communities residing the region. The people of Mao Naga tribe of Mao think themselves to have been migrated from China and first settled in Makhel of Mao (latitude 23.830 N to 25.680N and longitude 93.030E and 94.780E) and many of the Naga tribes trace their place of origin from there.

Genetic variation of 15 autosomal short tandem repeat (str) loci in sample of palestinian population residing in Iraq

Allele frequencies for the 15 autosomal STR loci included in the AmpFlSTR1 Identifiler TM PCR Amplification Kit panel from Applied Biosystems (D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, TH01, TPOX, CSF1PO, D19S433, D2S1338, D16S539) and several statistical parameters were estimated from a sample of 106 unrelated individuals. samples were extracted using a Prep Filer Forensic DNA Extraction Kit (Applied Biosystems, Foster City, CA), DNA quantified using Nano drop Thomson.

The hunger, poverty and silence: The synergy of threats to development and progress

With the spurt of the new global order in terms of liberalization, privatization and globalization that got off to a swash bucking debut in the decades of 90’s, the concept and perception of poverty and hunger have undergone a sea-change. Across the world, one billion people are now reeling under abject poverty and hunger. This is basically a threat to the human kind for their mere biological existence. Poverty is now even hatched a wider expanse of impacts over the geography of hunger. Around 895 million people across the world have been plunged to BPL (Below Poverty Line) status.

Review on positive role of Reactive Oxygen Species (ROS) in seed germination

In many seeds, the process of germination features testa rupture and endosperm rupture are two separate events. Endosperm rupture requires cell wall weakening in the endosperm layer. Puncture force measurements are a useful tool for quantifying this endosperm weakening. Various mechanisms have been proposed to promote endosperm weakening. Endosperm weakening requires cell wall weakening. This process involves cleavage of cell wall polymers or loosening of bonds between the polymers. Several molecular mechanisms have been proposed for endosperm weakening.

Studies on the qualitative changes in the amino acid, sugar and organic acid contents of tomato fruit during pathogenesis by alternaria solani

Qualitative changes in the amino acid, sugar and organic acid contents of the tomato fruit during pathogenesis causaed by Alternaria solani were investigated chromatographically. Marked differences in the amino acid, sugar and organic acid contents of the healthy and diseased tomato fruits were noted. Total in all only eight different amino acids, viz., Lysine, Arginine, Histidine, Aspartic acid, Glutamic acid, Alanine, Methionine and one Unidentified amino acid (Rf.

Estimating growth rates, decomposition analysis and instability of Groundnut crop production in Andhra Pradesh

The main objectives of the study are to examine the trends in area, production and productivity of groundnut in Andhra Pradesh over a period of 1995-96 to 2010-2011. Compound growth rates of area production and productivity were estimated by fitting semi log trend equation. Decomposition of output growth of groundnut was examined by fitting component analysis model. The study analyzed that area, production and productivity had decreased during the study period i.e.

Effect of organic and inorganic sources of nitrogen on growth, yield and quality of cotton (gossypium hirsutum l.)

A field experiment was conducted during 2013 at experimental farm, Faculty of Agriculture, Annamalai University to study the effect of organic and inorganic sources of nitrogen on growth, yield and quality of cotton. The soil of the experiment farm is deep clay, low in available nitrogen, medium in available phosphorus and high in available potassium. The experiment was conducted in randomized block design and replicated thrice.
