Dietary Behavior Related to Cancer Prevention in a Low Income Community

Background: The incidence of cancer is increasing in developing countries. Diet and cancer have a close relationship. Objectives: The objectives of this study were to measure the cancer prevention-related nutrition knowledge, attitudes, and practice and barriers related to healthy food in a low income community, and to assess their cancer worries. Subjects and Methods: This cross-section descriptive study was carried out in a slum area in Cairo on a convenience sample of 414 adults permanently residing in the area. A structured interview questionnaire was used for collecting participants' socio-demographic data, knowledge about cancer, attitude and practice towards cancer dietary prevention, cancer worry scale, and the barriers preventing eating healthy food. Results: The study revealed a wide range of participants' knowledge scores. Participants' attitude towards a healthy diet was also low. The most deficient practices were related to the intake of balanced diet and vitamins, practice of exercise, and cancer screening.  The most frequent barrier to a healthy diet was taste (42%), while the lack of information was the least (3.1%). Multivariate analysis showed that the knowledge score was positively predicted by cancer worry score. The attitude score was positively predicted by age and knowledge score, and the practice score by married status, crowding index, and attitude score. Conclusion: there is a poor level of knowledge and inadequate practices regarding cancer dietary prevention despite good attitudes, in addition to high worries about cancer. Implications for Practice: There is urgent need for awareness raising intervention programs for dietary prevention of cancer. Keywords: Cancer, Diet, Knowledge, Attitude, Practice, Barrie

Optimization of Renewable Energy-Based Smart Micro-Grid System

Optimization of renewable energy-based micro-grids is presently attracting significant consideration. Hence the main objective of this chapter is to evaluate the technical and economic performance of a micro-grid (MG) comparing between two operation modes; stand-alone (off-grid), and grid connected (on-grid). The micro-grid system (MGS) suggested components are; PV panels, wind turbine(s) inverter, and control unit in case of grid connected. In the stand alone mode diesel generator and short term storage are added to the renewable generators. To investigate the performance of the MGS; technically, detailed models for each component will be presented then the complete MGS model is developed. Another objective of this study is the economical evaluation of MGS by comparing the system net present cost (NPC) and cost of generated electricity for the two modes of operation; off-grid and on-grid

Taxonomic revision of the cultivated species of Mimusops (Sapotaceae) in Egypt, with new records

During the process of updating horticultural records of this genus in Egypt, five problems were identified: lack of publications, lack of clarity between species, numerous errors of identifications, loss of earlier documented records of identity, as well as, the introduction and cultivation of new plants during the 19th Century added to the complexity of the problem. In this study, the taxonomic aspects of genus Mimusops, were thoroughly studied to identify the most reliable characters for taxon delimitation. Our assessment was based on morphological characters representing habit, leaves, petioles, flowering pedicels, buds, floral parts, fruit and seed. Fieldwork have revealed the presence of four species, of which Mimusops kummel and M. zeyheri are new records. The latter species is represented in Egypt by M. zeyheri var. laurifolia. This variety has been neglected by many authors. Additionally, Mimusops elengi L. was believed to be cultivated in Egypt, but no materials have been encountered that could confirm it. The specimens earlier identified as M. elengi actually belong either to M. kummel or to M. laurifolia. A detailed description of the genus and species with photographs, an identification key, and synonymy for each taxon are provided

On Congruences of Principal GK2-Algebras

We investigate some features of principal GK2-algebras (PGK2-algebras). Necessary and sufficient conditions for a principal GK2- algebra to have 2-permutable congruences are obtained. Furthermore, it is established how 2-permutable congruences are characterized using pairs of principal congruences. Also, a generalization of the 2-permutability of the primary congruences of the GK2-algebras concept to the concept of the n-permutable congruences is provided. We round off with strong extensions of principal GK2 -algebras

The Correlation of Critical Thinking Disposition and Approaches to Learning among Baccalaureate Nursing Students

Role of MR as Non-Invasive Procedure in Assessment of Fatty Liver Infiltration in Potential Liver Donor Versus Biopsy

Background: Significant hepatic steatosis can impact surgical results in the donor. Liver biopsy is the gold standard for hepatic steatosis diagnosis and assessment. Liver biopsy is not useful for screening or monitoring hepatic steatosis in living liver donors. MR spectroscopy and the proton density fat fraction (FF) approach have shown encouraging results in assessing hepatic steatosis. Aim and Objectives: is to correlate between the MRI-PDFF techniques as a non-invasive technique in pre-operative assessment   of quantification of liver fat in comparison to the liver biopsy. Patients and Methods: This prospective control study was conducted at the National Hepatology and tropical medicine research institute including 42adult potential hepatic donors. The duration of the study ranged from 6-12 months. Results: regarding median fat percent for selected patients (n=42) We found that correlation between both reading was significant strong positive one (spearman correlation =0.960, p<0.001). despite the recorded liver fat percent through MRI PDFF was higher in males when compared to females, this was statistically insignificant. MRI PDFF true positive was 86.8% with false positive of 50% and true negative was 50% with false negative of 13.2%. Conclusion: Noninvasive MR hepatic PDFF technique with IDEAL sequence is a precise reliable technique for quantitative assessment of hepatic steatosis with high sensitivity, specificity and accuracy of It is recommended to be a part of preoperative liver evaluation in living donors and selectively performing liver biopsy in donor candidates diagnosed to have substantial steatosis based on MR PDFF findings
