Photobleaching of Sn(IV) chlorine e6 dichloride trisodium salt in different environments
The photobleaching of Sn(IV) chlorine e6 dichloride trisodiuim salt in variety of solvents was investigated. The absorption of photosensitizer in polar solvent was much higher than in non-polar solvent. The results prove that this photosensitizer was high water soluble. The photosensitizer absorption decreased at all bands for all solvents. Increasing the irradiation time leads to gradual decrease in the absorption of photosensitizer in solvents. The photosensitizer binding to the protein will result in a reduction of the diffusional movement of the photosensitizer to equalize the protein. The presence of serum in the environment leads to increase in the photobleaching rate and response to light as well. A new peak position of absorption was observed in the ultra violet region with the presence of serum. Singlet oxygen was found to be responsible for photobleaching.Key words: Sn(IV) chlorine e6, photobleaching, photoproduct
Serum resistin is associated with C-reactive protein and LDL- cholesterol in type 2 diabetes and coronary artery disease in a Saudi population
Aims
Resistin is an adipocyte-derived factor implicated in obesity-associated type 2 diabetes (T2DM). This study examines the association between human serum resistin, T2DM and coronary heart disease.
Methods
One hundred and fourteen Saudi Arabian patients (male: female ratio 46:68; age 51.4 (mean ± SD)11.7 years; median and range: 45.59 (11.7) years and BMI: 27.1 (mean ± SD) 8.1 Kgm2 median and range: 30.3 (6.3) were studied. Serum resistin and C-reactive protein (CRP), a marker of inflammation CRP levels, were measured in all subjects. (35 patients had type 2 diabetes mellitus (T2DM); 22 patients had coronary heart disease (CHD).
Results
Serum resistin levels were 1.2-fold higher in type 2 diabetes and 1.3-fold higher in CHD than in controls (p = 0.01). In addition, CRP was significantly increased in both T2DM and CHD patients (p = 0.007 and p = 0.002 respectively). The use of regression analysis also determined that serum resistin correlated with CRP levels (p = 0.04, R2 0.045).
Conclusion
The findings from this study further implicate resistin as a circulating protein associated with T2DM and CHD. In addition this study also demonstrates an association between resistin and CRP, a marker of inflammation in type 2 diabetic patients
Recent Sighting of Smooth-Coated Otter Lutrogale perspicillata maxwelli in Hawizeh Marsh (Southern Iraq)
Since 1956, there were very few sightings of Iraq Smooth-coated Otter (Lutrogale perspicillata maxwelli) especially after the Iraqi marshlands inundation. In April 2015, an adult male Iraq Smooth-coated Otter was trapped near Al-Edheam, in the northern part of Hawizeh Marsh (Southern Iraq). The recent sighting along with present photographic record represents very rare evidence documenting the occurrence of L. p. maxwelli otter in Iraq since the1950s
New localities of the Eurasian otter Lutra lutra (Linnaeus, 1758) in the upper Euphrates river basin, a remarkable range extension in western Iraq
Records of the Eurasian Otter (Lutra lutra) have been confined to the waterbodies of southern, central, and northern Iraq (Kurdistan). Although its status in the Upper Euphrates River Basin in western Iraq is not fully explored, it seems to be rare. In August 2019, two adult Eurasian otters were reported from two new localities in Anbar Province after being strangled by fishing nets. These records represent the first photographic evidence for a remarkable range extension of the Eurasian Otter distribution range in western Iraq
Quadtree partitioning scheme of color image based
Image segmentation is an essential complementary process in digital image processing and computer vision, but mostly utilizes simple segmentation techniques, such as fixed partitioning scheme and global thresholding techniques due to their simplicity and popularity, in spite of their inefficiency. This paper introduces a new split-merge segmentation process for a quadtree scheme of colour images, based on exploiting the spatial and spectral information embedded within the bands and between bands, respectively. The results show that this technique is efficient in terms of quality of segmentation and time, which can be used in standard techniques as alternative to a fixed partitioning scheme
The Authors Abuse of the Moral Right in the Jordanian Legislation: A Comparative Study
The moral rights of the author are fundamental and protect their intellect and creativity. Despite its importance to the author in particular and society in general, leaving such rights unrestricted is not acceptable because the objective of the law is to regulate various transactions and relationships between people. Therefore, establishing frameworks governing copyright law is deemed useful. By way of examining Jordanian, local, and international legislation, the researchers find that the legislator has not effectively regulated this matter to prevent the author from exercising their moral rights in a way that harms others. Despite the close connection between the moral right and the economic one, the issue of moral right abuse by the author has not been addressed, even though its elements are present in some of the authors practices. Furthermore, the legal texts tackling the subject are more contentious due to their vague and ambiguous wording, leaving legal interpreters to exert effort to understand the intentions behind these words and terms. In the quest to investigate this topic, the study draws several conclusions, the most important of which is the absence of any obstacle to applying the theory of the authors abuse of their moral rights in their practices. The study also shows that the value of compensation specified in the law is not defined by criteria, making it impossible to estimate the value of the loss suffered by the affected party as a result of the authors exercise of their moral rights, as the value of profit is not identified
Deep fingerprint classification network
Fingerprint is one of the most well-known biometrics that has been used for personal recognition. However, faked fingerprints have become the major enemy where they threat the security of this biometric. This paper proposes an efficient deep fingerprint classification network (DFCN) model to achieve accurate performances of classifying between real and fake fingerprints. This model has extensively evaluated or examined parameters. Total of 512 images from the ATVS-FFp_DB dataset are employed. The proposed DFCN achieved high classification performance of 99.22%, where fingerprint images are successfully classified into their two categories. Moreover, comparisons with state-of-art approaches are provided
Knowledge and Attitudes of Young People toward Mental Illness: A Cross Sectional Study
The aim of the study was to investigate young Jordanians’ knowledge and attitudes toward people who have a mental illness. A cross sectional design was utilized. A convenient sample of 858 participants aged between 15–24 years old completed a survey. Participants under 19 years were accessed through their schools and those 19 years and above were accessed through universities. Results showed that although the majority of university and school students’ responses were generally consistent, they disagreed on 11 items on the survey; for example, 186 (39.3%) of university students agreed that mental illness has a biological origin compared with only 119 (30%) of school students. The majority of young people 737 (85.9%) were willing to learn and 792 (92.3%) felt that they have to help people with mental illness, which make them willing to learn. In conclusion, the findings provide insights for decision makers and researchers in Jordan about young peoples’ knowledge and attitudes toward mental illness. Increasing young adults’ literacy through introducing educational programs such as mental health first aid courses will enrich their knowledge; help change attitudes and reduce stigma toward people living with mental illness
