Abstract:The steady state advection-diffusion equation (ADE) has been solved analytically to simulate the dispersion of pollutants in the atmospheric boundary layer (ABL) taking into account the vertical variation of the wind speed and eddy diffusivity. The solution is based on the assumption that the ABL height (h) is divided into sub-layers and within each sub-layer the ADE is solved by using the separation of variables method assuming the mean values of wind speed and eddy diffusivity. The obtained model was used to predict the concentration of Iodine-135 in air around a Research Reactor at Inshas, Cairo Egypt. The statistical analysis that performed between the calculated and experimental values of concentration shows a good agreement between them.
Abstract:Background: In recent years, the prevalence of obesity has steadily increased and has emerged as a global epidemic. Childhood is a period in which healthy nutrition behaviors are formed. The education provided on this subject during this period is of great value, insofar as it helps individuals to develop healthy habits and attain wholesome, quality lives in the future. Family and school constitute two important social environments where nutrition habits are created.\nObjectives: This study aims to examine the effects that nutrition education given to primary school-age children has on their nutrition behaviors, nutrition knowledge and body mass index.\nMethod: The study was conducted with 173 students, who were enrolled in the 1st, 2nd, 3rd, and 4th grades of a private school, and their parents. The research data were collected using a survey form, the Food Consumption Frequency Form, the Child Nutrition Knowledge Form, and the Body Mass Index Values Form. As part of the study, children and parents were given trainings that involved introducing food items and explaining healthy nutrition habits. Parents underwent one training session, while the children received training at four different times, namely, at the start of the education program and in the 1st, 2nd and 3rd months thereafter. The obtained data were evaluated in a computer environment using the SPSS program.\nResults: After undergoing the education program on nutrition, the children\

The statistically values (X±SE) were, 17.90±0.44 kg for live weight; 50.48±0.46 cm for wither height; 50.09±0.45 cm for rump height; 56.00±0.47 cm for body lenght; 17.59±0.19 cm for chest width; 20.92±0.25 and 57.64±0.57 cm for depth and circumference; 9.72±0.09 and 8.88±0.09 cm for front and behind cannon bone circumference; 23.50±0.17, 9.68±0.10 and 14.17±0.15 cm for head, face and ear length; 10.83±0.14 cm for ear width; 13.44±0.13 and 4.48±0.07 cm for ears and eyes interval; 20.53±0.21 cm for mouth circumference and 35.38±0.36 cm for tail length. Heterozygosity (Ho) value was calculated as 0.745 in Zağar dogs. Find a new haplotype (unspecified in other dog breeds) was determined in the mtDNA D-loop analysis which was called A286 in Zağar genotype. As a result, this research is revealed that Zağar dogs were found to be different as morphological and genetic characteristics from which were grown other dog breeds in Turkey.
Abstract:The association of human papillomavirus (HPV) infection with cervical cancer and head and neck cancer is well established, but the relevance in breast cancer is controversial. Several studies have shown that oncogenic HPV DNA, which is currently used in the screening and diagnosis of breast cancer, can be detected not only in breast cancers but also in benign breast lesions. For this reason, this study targeted HPV E6/E7 mRNA of carcinogenic high-risk HPV genotypes and analyzed HPV infection and its correlation with breast cancer in breast cancer tissue of Korean women.\nIn the present study, HPV E6/E7 mRNA was evaluated using a reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR) assay, with RNA extracted from breast formalin-fixed paraffin-embedded (FFPE) tissues, including tissues from 67 women with breast cancers and 10 with fibroadenomas. A total of 67 cDNAs from FFPE breast tissue was used for HPV genotyping with the CervicGen HPV RT-qDX kit, which detected 16 high-risk HPV genotypes (HPV 16, 31, 33, 35, 52, and 58 for Alpha-9; HPV 18, 39, 45, 51, 59, and 68 for Alpha-7; and HPV 53, 56, 66, and 69 for Alpha-5, 6) through detection of HPV E6/E7 mRNA expression. The results showed that HPV E6/E7 mRNA expression was not detected in all breast tissues including breast cancers and fibroadenomas, and there was no association between HPV and breast cancer.\nTherefore, investigate the relationship between HPV infection and breast cancer development, more samples should be used to compare results according to molecular diagnostic methods and to confirm the correlation of related tumor-suppressor genes.
Abstract:In the past years cable structures usage has been globally increased and buildings have been widened in scale due to structural system easy combination with different materials and elements. Representing linear tensile elements usually produced from steel, cables have a great ability to withstand large loads and support the structures in the diverse climatic conditions. \nDespite the historical background overview of cable structures article reveals structural developments of the system and changes in cables implementation. Changes in the scale and function led to the modifications in the system and appearance of new cladding materials affected the function and forms of cable structures. Article keeps open the subject of cables combination with traditional materials of existing buildings. \nKauffman Center for the Performing Arts located in Kansas City in USA was chosen as case study to reveal construction methodology of large scale cable structures considering impact of the climate.
Abstract:In the modern world of technology, tools and gadgets, a huge amount of data is produced every second in applications ranging from medical science, education, business, agriculture, economics, and retail to telecom. Higher education institutes play an important role in the overall development of any nation. For the successful running of these institutions, continuous monitoring for improving the quality of education and students is required, which is the subject of this paper. Huge amount of data that education systems produce increases rapidly every year and it is difficult by traditional techniques to manage, predict and analyze this data. One way to address this challenge is through mining large amount of data. It enables the institutions to use their present reporting trends to unmask hidden patterns and identify the relationships in huge databases. These patterns are then used to forecast individual behavior with immense veracity. As an outcome of this, institutions are able to take necessary actions for improving the student’s dropout, grade, retention, predicting the student’s performance, weak areas and estimate the number of enrollments in a particular course. Researchers have widely used classification, categorization, estimation, regression and clustering approaches for extracting meaningful information to predict about various aspects of the students. However, there is a huge scope of exploring latest and emerging trends in education domain. Present paper conducts a detailed and exhaustive study on techniques and approaches implemented in education mining.
Abstract:This study investigates the effectiveness of intra-mammary ozone administration in a dry period and at the time of delivery for preventing mastitis in herds with contagious mastitis. The cows were divided into five groups with 10 cows in each. Group 1 was administered ozone-containing foam preparation via the teat canal into four udder lobes for 5 seconds at the beginning of the dry period; Group 2 was administered ozone at the beginning of the dry period and at the time of delivery; Group 3 was administered ozone at the time of delivery; Group 4 was administered dry period udder preparation at the beginning of the dry period; and Group 5 was administered only teat seal at the beginning of the dry period. No statistically significant difference was found between the cows with regard to the SCC values at the beginning of the dry period and at the time of delivery (in cows without clinical mastitis, n=25). The SCC values were reported to decrease when the values at the beginning of the dry period and at the time of delivery were compared. All cows except two in Group 1 were detected to have clinical mastitis according to the frequency of microbial isolation in milk at the time of delivery. In conclusion, intra-mammary ozone administration did not prevent mastitis in the dry period or at the time of delivery in herds with contagious mastitis; moreover, it was determined to increase the rate of clinical mastitis in the postpartum period.
Abstract:The article is the result of a study that sought to understand the required dynamic crossing points of a public-private partnership. The call for research proposals Vale-FAPs was the instrument that concretizes the partnership established by Vale with the São Paulo Research Foundation (FAPESP), Minas Gerais State Agency for Research and Development (FAPEMIG) and Amazon Foundation of Support for Studies and Research (FAPESPA). The article focused on the partnership Worth and FAPEMIG and adopted a qualitative approach and your analysis based on theoretical-methodological assumptions of Actor-Network Theory. We conclude that the interactions, agreements, and negotiations made during the partnership were positive. The Valley partnership and FAPEMIG allowed a learning project management for organizations. The partnership enabled the approximation of Vale with scientific and technological institutions (STIs) and researchers of these STIs that the company had no contact with. We observed that the work of monitoring and joint monitoring by the organizations contributed to the good execution of the partnership, bringing benefits and contributed to the internalization of the results.
Abstract:Field experiments were conducted with the objectives to evaluate the physiological response of eggplant stomatal resistance (rs) to various deficit irrigation regimes applied with subsurface and surface drip systems under the Mediterranean climatic conditions. In the study, surface drip (DI) and subsurface drip systems (SDI); 3-day and 6-day irrigation intervals (IF3, IF6); and full irrigation (FI), deficit irrigations (DI50, DI75) and Partial Root Drying (PRD50) were evaluated in split-split plot design. Irrigation systems, intervals and regimes resulted in significantly different yields. DI performed slightly better than the SDI in the first year but performed similarly in the second year regarding the yield. Water stress reduced eggplant yield significantly and PRD50 treatments resulted in the lowest yields. Smaller rs values were measured in FI plots in both drip systems with 3-day interval than deficit irrigation treatments and longer irrigation frequency plots. Significant relationships among rs and yield were obtained. The results revealed that eggplant should be irrigated at rs value of approximately 30 and 40 s m-1 for high and good quality yields. Thus rs can be used for irrigation scheduling for eggplant. The physiological response of eggplant to different water stress levels can be used for optimization and sustainability of crop production in areas where water sources are limited or expensive.
Abstract:In this study, the coating of Inconel 718 superalloy synthesized with elemental powders on the AISI 1010 steel substrate was carried out by resistance sintering. Microstructure and phase analyzes of the coated sample were performed by means of optical microscopy, scanning electron microscopy (SEM-EDS) and x-ray diffraction (XRD) analysis. Inconel 718 superalloy coated specimens were applied to double aging heat treatment to provide superior mechanical and high temperature properties. The microstructure images of the samples applied heat treatment after coating process indicate that they have good adherence capability and low porosity content. In the SEM-EDS results obtained from the coating-substrate interface after applying double aging heat treatment, it was identified that the mutual diffusion occurred at the interface. XRD analysis depicts that the phases formed in the synthesized Inconel 718 superalloy coating layers were as a major phase, Cr2O3 minor phases. Moreover, MC and trace phases were detected in addition to these phases in double aging heat treated coating.
