Separation Axioms on Soft SIgδs-Closed Sets

In this paper, we have introduce and study weak separation axioms such as soft Igδs-T0, soft Igδs-T1, soft Igδs-T2, δ-T3/4, Igδs-regular space in soft ideal topological spaces and also investigate some of its characterizations and properties with the help of general topology concepts. Also give relationships between the above new regualr spaces. Then we give sufficient and necessity condition between soft SIgδs-closed sets and soft singleton sets in soft Igδs − T1 space

Soft Igδs-Closed Functions

In this paper, we have introduced a new class of open and closed functions called soft Igδs-closed and soft Igδs-open functions in ideal topological spaces and also investigated some of its characterizations and properties with the existing sets

Determination of the rate of kill, mode of action, and the bioactive components from the ethyl acetate sub-fraction of methanol extract of Phyllanthus amarus.

The time-kill rate of methanol extract of Phyllanthus amarus was determined in this study which showed that the extract caused a reduction of the viable cells of all the test bacteria after a contact time of 30 mins and there were virtually no surviving cells of all the test bacteria after a contact time of 180 mins. The extract was also found to cause leakages of cellular materials such as potassium ions, sodium ions, protein and nucleic acids from the test bacteria which led to the loss of cell viability. The ethyl acetate sub-fraction of the extract was analyzed by GC-MS and FTIR analysis and the result revealed the presence of Phytochemicals such as 1, 2-Benzenedicarboxilic acid mono (2-Ethylhexyl) ester, Columbin, 2-(6-Methylpyridin-2-ylmethyl) cyclohexane, 2(1H) Naphthalenone,3,5,6,7,8,8a-hexahydro-4,8a-dimethyl-6-(1-methylethenyl) which have all been reported to possess antibacterial activity against both gram-positive and gram-negative bacteria. The result of this study will contribute to the baseline data on the pharmacodynamics of the extract if applied as herbal medicine for human treatment thereby reducing the dosage and period of treatment. The finding also revealed that the ethyl acetate sub-fraction of methanol extract of P. amarus contains antibacterial phytochemicals that may be used to develop more potent, safe and cheap antimicrobial agents using nanotechnology. &nbsp

BLACKFACE SURVEILLANCE CAMERA DATABASE FOR EVALUATING FACE RECOGNITION IN LOW QUALITY SCENARIOS

Many face recognition algorithms perform poorly in real life surveillance scenarios because they were tested with datasets that are already biased with high quality images and certain ethnic or racial types. In this paper a black face surveillance camera (BFSC) database was described, which was collected from four low quality cameras and a professional camera. There were fifty (50) random volunteers and 2,850 images were collected for the frontal mugshot, surveillance (visible light), surveillance (IR night vision), and pose variations datasets, respectively. Images were taken at distance 3.4, 2.4, and 1.4 metres from the camera, while the pose variation images were taken at nine distinct pose angles with an increment of 22.5 degrees to the left and right of the subject. Three Face Recognition Algorithms (FRA), a commercially available Luxand SDK, Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were evaluated for performance comparison in low quality scenarios. Results obtained show that camera quality (resolution), face-to-camera distance, average recognition time, lighting conditions and pose variations all affect the performance of FRAs. Luxand SDK, PCA and LDA returned an overall accuracy of 97.5%, 93.8% and 92.9% after categorizing the BFSC images into excellent, good and acceptable quality scales.

Monsoon prawn fishery by 'Matabala' along the Mangalore coast—a critical study

The article presents a report on a critical study about 'Matabala' also known as 'Disco net' (small version of purse seine net made of nylon), a gear used along the Mangalore coast during monsoon period. It was considered that the net was much more size specific to catch large sized prawns

Thalassaemia (part 2): Management

The management of thalassaemia with a severe phenotype includes blood transfusion, iron chelation, bone marrow transplantation, prenatal diagnosis and national programmes to co-ordinate these in countries with a high prevalence. If blood transfusion and iron chelation therapy are not administered regularly, as was the case historically and as is still the case in many poorer regions, progressive deterioration occurs, viz. impaired growth and development, hepatosplenomegaly, bony abnormalities, cardiac failure, increased susceptibility to infections and premature mortality. Remarkable progress has been made in the past few decades, which has led to much-improved survival rates. Transfusion therapy has evolved to a hyper-transfusion regimen designed to maintain a physiological haemoglobin level and achieve a post-transfusion haemoglobin of 14 g/dL, which, as a matter of course, necessitated intensification of iron chelation. The development of effective oral iron chelators has led to improved compliance. Exploration of novel therapeutic approaches continues, with several agents under study. The prospect of gene therapy is particularly exciting as it has potential to provide cure on a large scale. Currently, regular blood transfusion and iron chelation therapy remain the cornerstone of management of thalassaemia major

Phytochemical screening and proximate analysis of young Cola acuminata leaves

Oxidative stress and impaired antioxidant system have been implicated in the pathophysiology of diverse disease states. Phytochemical screening and proximate analysis of dried young cola nitida leaves used in folklore medicine were carried out. The result revealed the presence of bioactive components comprising of alkaloids, phenolic acid, carotenoids, and flavonoid. Quantitative phytochemical analyses showed that alkaloid have the highest concentration. Proximate analysis of the sample showed the moisture content of the sample is (23.10±0.12), carbohydrate (36.80±0.25), crude fibre (19.20±0.1), crude protein (13.50±0.10), and ash content (6.70±0.07). The presence of secondary metabolites in this plant is indicative that if well researched, novel bioactive compounds can be discovered in it
