The recognition system of sickle cell anemia by using hidden markov model

The study of genetic mutations, that is responsible for diseases , is an important issue in genetics for its close relationship with the genetic evolution of living organisms , In this paper we present an algorithm that is bases on the Hidden Markov Models of recognition to the mutation that causes one of the most common genetic diseases, Sickle Cell disease, thus diagnoses the person state (infected, uninfected) , This method is applied to DNA sequence , Deoxyribonucleic acid, the practical application shows that the rate of recognition of an infected person equals (99%) and the rate of re

Hepatobiliary surgery in liberia: a case report of a 49-year female with acute cholecystitis

Acute cholecystitis refers to a syndrome of right upper quadrant pain, fever, and leukocytosis associated with gallbladder inflammation, which is usually related to gallstone disease. More than 90% of cases of acute cholecystitis are associated with cholelithiasis. Cholelithiasis is said to be an uncommon disease in tropical Africa. This contrasts with the high incidence of gallstones in western Europe and the United States. In review of the literature, there has been no documented or published data on the management of Acute Calculous Cholecystitis in Liberia.

Analysis of binding in an octasaccharide of siparuna guianensis aublet by methylation, and nmr studies

Siparuna guianensis Aublet is known by several popular names according to the country and / or region of distribution in Brazil. In the Cerrado regions in the states of Mato Grosso and Goiás, it is known by the name of negramina, is of the family Siparunaceae and consists of two genera, Glossocalyx and Siparuna, with approximately 65 species of shrubs and trees, except for 15 species that are trees of 20 to 40 meters high, with trunks with diameters greater than 120 cm, which usually occur in the Amazon. S.

A comparative study on the characteristic compressive strength of reclaimed rubber concrete

Disposal of waste tires is found to be one of the major problems faced by the local authorities throughout the world. A few countries recycle the waste tires which is called as Reclaimed rubber(RR) useful in concrete replacing conventional aggregates. This research work is focused on comparing the characteristic compressive strength test results of reclaimed rubber concrete used in M40 grade experimentally and analytically using genetic algorithm.

Superparamagnetism – a size effect

In many ferromagnetic materials when the size of the particle is reduced to nanodimension, super behaviour called superparamagnetism occurs. The hysteresis loop change unusually and there is no remenance and coercive field. The M-H curve passes through the origin i.e. it needs no energy to bring back the sample from magnetised form to zero magnetisation.

Simulation of hybrid amplifiers (edfa and raman amplifier) on 40gbps on 16 users wdm system

To fulfill the need of higher bandwidth, enhanced number of users, enhanced speed of communication of today’s users, the concept of WDM and fiber optic was developed. WDM is a wavelength division multiplexing. In which the multiple input signals are combined together and transfers as a single input. It uses the concept of multiplexing and de-multiplexing. WDM system comprises of amplifiers that are used to enhance the performance of the optical fiber system. This study analyzes the working of Hybrid amplifiers i.e.

Copy move image classification by feature optimization with support vector machine approach

Copy-move is a simple and effective operation for creating digital image forgeries, where an area of an image is copied and pasted to a different location in that image. Generally, a forger uses some affine transformations to make the changes visually intact. Most existing copy-move detection methods are not effective when copied regions are under geometrical distortions.

Occurrence of termites (isoptera) in natural and anthropized sand dunes areas in southern Brazil with biological notes on the species

The knowledge about termites in restinga (sand dunes and adjacent areas) is incipient in Santa Catarina (SC) State coast, southern Brazil. Aiming to verifiy the diversity of the termitofauna, the presence of possible exotic species as well as aspects of the biology of the existing species, a survey was done in a natural and in an anthropized portion of restinga, from May to December 2009, during 90 hours. Termites were searched visually on different substrates at both places, sampled and conserved for identification. Nests were also searched, opened and studied.

16s Rrna gene sequence, secondary structure and restriction sites analysis of isolated actinomycetes from soil samples of botanical garden, Karnatak University, Dharwad

Current researchers are more emphasised towards microbes to meet the antibiotic requirement of mankind. And in this study we made an attempt for the search of antibiotics through isolation of actinomycetes and analysis of their antibiocity through 16s rRNA gene sequencing and identification of restriction site. An Actinomycete species (SN-4) was isolated from botanical garden soil samples of the Karnatak University, Dharwad, India. Morphological, physiological, biochemical and 16S ribosomal RNA studies suggested that the isolate belongs to Streptomyces sp.
