Blind image separation based on exponentiated transmuted Weibull distribution

In recent years the processing of blind image separation has been investigated. As a result, a number of feature extraction algorithms for direct application of such image structures have been developed. For example, separation of mixed fingerprints found in any crime scene, in which a mixture of two or more fingerprints may be obtained, for identification, we have to separate them. In this paper, we have proposed a new technique for separating a multiple mixed images based on exponentiated transmuted Weibull distribution. To adaptively estimate the parameters of such score functions, an efficient method based on maximum likelihood and genetic algorithm will be used. We also calculate the accuracy of this proposed distribution and compare the algorithmic performance using the efficient approach with other previous generalized distributions. We find from the numerical results that the proposed distribution has flexibility and an efficient resultComment: 14 pages, 12 figures, 4 tables.

ICA and Sparse ICA for Biomedical Signals

Biomedical signs or bio signals are a wide range of signals obtained from the human body that can be at the cell organ or sub-atomic level Electromyogram refers to electrical activity from muscle sound signals electroencephalogram refers to electrical activity from the encephalon electrocardiogram refers to electrical activity from the heart electroretinogram refers to electrical activity from the eye and so on Monitoring and observing changes in these signals assist physicians whose work is related to this branch of medicine in covering predicting and curing various diseases It can also assist physicians in examining prognosticating and curing numerous condition

Plaguicidas y cáncer de mama en mujeres cordobesas

Exposure to environmental contaminants is an important public health problem, specially because of its possible carcinogenic effect. The raising incidence of cancer breast in Spain, together with the absence of clear association between this pathology and exposure to pesticides motivated us to assess the possible etiological role of pesticides in breast cancer development among women living in the province of Cordoba.We conducted a case-control study including women subjected to surgical interference because of breast lesions in Reina Sofia University Hospital. All women were subjected to interview questionnaire, histopathological study of the lump and determinations of four pesticides (HCB, HCH, p, p’DDE and Aldrin) in breast fat using gas chromatography.The histopathological study identified 69 women with malignant lesions (cases) and 65 women with benign lesions (controls). Analytic determination of the 4 pesticides detected high levels of p, p’DDE in all samples, followed by HCB and Aldrin and less levels and frequency of HCH.The univariate analysis identified the age, lactation period, and levels of Aldrin as risk factors for malignant lesions, meanwhile the multivariate analysis identified the levels of Aldrin as the most significant risk factor (p < 0.001).Causal relation was found between Aldrin and breast cancer, suggesting the need for future studies taking in consideration possible confusion factors.La exposición a contaminantes ambientales constituye en la actualidad un problema importante en salud pública, sobre todo con respecto al papel que dichos tóxicos juegan como carcinogenéticos. Este hecho junto con la incidencia creciente del cáncer de mama en España y de que no existe una relación clara entre esta patología y la exposición a plaguicidas, conduce a plantearnos evaluar el papel de los plaguicidas como factor de riesgo en el cáncer de mama en mujeres cordobesas.Se realiza un estudio de casos-controles en 134 mujeres que fueron sometidas a intervenciones quirúrgicas por lesiones mamarias en el Hospital Universitario Reina Sofía de Córdoba. A todas se les realiza un cuestionario, así como un estudio anatomopatológico y determinaciones en grasa mamaria de cuatro plaguicidas (HCB, HCH, p,p’DDE y Aldrín) mediante cromatografía de gases.Tras el estudio anatomopatológico se estableció que 69 presentaban lesiones malignas (casos) y 65 lesiones benignas (controles). Las determinaciones analíticas respecto a los 4 plaguicidas, detectan niveles elevados de p,p’DDE en todas las muestras, seguidas del HCB y Aldrín y en menores niveles y muestras se detecta el HCH.El análisis univariante detectó la edad, duración de la lactancia y niveles de Aldrín como factores de riesgo en las lesiones malignas, pero el análisis multivariante identificó los niveles del pesticida Aldrín como el factor más significativo en dichas lesiones (p < 0.001).Se establece la relación causal entre Aldrín y cáncer de mama, y se sugiere la necesidad de realizar nuevos estudios para eliminar los factores de confusión

Assessing Environmental Management Plan Implementation in Water Supply Construction Projects: Key Performance Indicators

Assessing the implementation of environmental management plans (EMPs) in construction projects is crucial for meeting environmental sustainability goals and reducing potential adverse impacts. By using performance indicators (PIs), stakeholders can objectively measure the performance of EMP implementation, identifying areas of success and areas that may require improvement. Therefore, this study aims to examine the PIs for assessing EMP implementation in water supply construction projects, using Saudi Arabia as a case study. Data from semi-structured interviews and a systematic literature review were used to develop a potential list of PIs. Then, the PIs were used to create a survey and distributed to industry professionals. Data from 112 respondents were analyzed using mean ranking analysis, the normalization method, exploratory factor analysis (EFA), and fuzzy synthetic evaluation (FSE). Eighteen critical PIs for assessing EMP implementation in water supply construction projects were identified, including public safety, road safety hazards, construction waste, clogged drainage, irregular flooding, the spilling of chemical substances, slope failures, soil erosion, landslide occurrence, increased schedule waste, changes in the color of bodies of water, oil/fuel spills, restricted site accessibility, the smell of run-off water, traffic accidents on construction sites, the spread of disease, changes in the color of run-off water, and overflowing silt traps. The EFA revealed that PIs can be grouped into three underlying constructs: fluid-related indicators, health and safety-related indicators, and site environment-related indicators. The FSE results confirmed that all PIs are between moderately critical to critical. This study’s significance lies in its examination of PIs that aim to improve the environmental performance of water supply construction projects. Understanding which indicators are most effective allows for targeted improvements, helping to minimize negative environmental impacts and ensuring sustainable practices. Finally, this study is a pioneer in examining the critical PIs for assessing EMP implementation in water supply construction projects

Production of Phytate-Degrading enzyme from Malaysian soil bacteria using rice bran containing media.

The aims of the study were to observe the effects of different concentration of rice bran in different media on phytase synthesis and to optimize the temperature and pH of the media for phytase production by those bacterial strains. Three bacterial strain isolates obtained from the soil of Malaysian maize plantation were used to produce phytase. In this study, the effects of different rice bran concentration, incubation temperature and initial pH-values of the media on phytase production were evaluated. Incorporation of 7.5% rice bran has the inducible effect on all the bacterial tested. In respect to phytase production, the best cultivation media and cultivation time for Bacillus cereus ASUIA260 was PFE with 7.5% rice bran after 3 days, whilst for Pantoea stewartii ASUIA271 and Enterobacter sakazakii ASUIA279, it was LB with 7.5% rice bran after 3 days and 5 days, respectively. The arrangement of those isolates according to their ability to produce phytases were E. sakazakii ASUIA279 > P. stewartii ASUIA271 > B. cereus ASUIA260. Production of phytase by those bacteria was triggered by the high content of organic phytate in the rice bran. Optimum temperature for phytase production of B. cereus ASUIA260 was 41 ºC compared to P. stewartii ASUIA271 and E. sakazakii ASUIA279 with 33 ºC and 37 ºC, respectively. Optimum initial pH for phytase production of B. cereus ASUIA 260 was pH 7.2, while P. stewartii ASUIA271 and E. sakazakii ASUIA 279 were both at pH 6.0
