Degraded document Image processing is special area of Document Image Analysis (DIA) providing a platform for researchers in the recent period. Binarization is the primary step in document image processing to identify the object information from the background of an image. In the degrade documents binarization is used for separating object information from the noisy background of an image. Due to the nonlinear variation in the pixel intensities of the original document, either global or local thresholding methods are used. In this approach to find the pixels that are likely associated with background information, during the separation of object information. In this context we propose a technique which is based on the complement of the original image. By using this technique ancient text documents and palm leaf manuscripts are evaluated and finally the qualities of the resultant images are evaluated by different qualitative metrics.
Mechanical ventilation (MV) is a supportive and life-saving therapy, however, it can cause ventilator-induced lung injury as a common complication. Thus, recruitment manoeuvres (RM) are applied to open the collapsed alveoli to ensure sufficient alveolar surface area for gas exchange. In the light of fact that positive pressure ventilation is currently the standard treatment to improve pulmonary function, extrathoracic negative pressure is considered as an alternative form of respiratory support. The aim of the study was to estimate the proinflammatory and oxidative response during MV and lung injury as well as the response after RM. All studied parameters were assessed at the following time points: T1-spontaneous breathing, T2- MV, T3- lung injury, T4 –RM. During MV (T2) elastase, MPO, ALP release, nitrite and superoxide generation significantly increased, whereas in later measurements a decrease in these values has been shown. The MDA plasma concentration significantly (p<0.05) increased at T2, reaching the level of 13.30±0.87 nmol/ml, at other time points the values obtained were similar to the baseline value of 9.94±0.94 nmol/ml, whereas the gradual decrease in SOD activity at time T2-T4 points in comparison with the baseline value was found. During experiment both neutrophil activity and oxidative stress indicate exacerbated response after MV and lung injury by bronchoalveolar lavage, however, extrathoracic negative pressure system as the MR ameliorates damaging changes which could further lead to serious lung injury.
In this study, a web application framework named “iCan” is proposed for people with special needs who can\\\'t move from place to another and they haven\\\'t the ability to get outside the home. It is a great step for their life to make the daily requirements easier. This type of web applications aim to serve those people but unfortunately is rarely or may not exist. The web application promotes miscellaneous services to choose for registered people in the system. The offered services are transportation offices, shopping centers such as markets, training centers, health care centers and other service providers. The proposed application will be implemented using PHP Laravel, JavaScript, jQuery, HTML5, CSS3 and BootstrapAbstract should convey the importance of your research in a concise and logical manner.
In general, solid waste materials if accumulated are of potential negative impact to the environment although it has sometimes an economic value if it is recycled. Among these solid waste materials one can mention, the exhausted plastic bottles of Polyethylene Terephthalate (PET) chemical composition. The increase in the consumption of these bottles has been occurred dramatically. Therefore, recycling of PET as aggregates in concrete is one of the important topics of interest to researchers in last decades. The aim of the present work is to make a comparative study on the effect of adding two kinds of PET as replacement of fine aggregates, with different percentages, on concrete properties. To achieve the goal of this research, seven mixtures have been investigated. In addition to plain concrete, two forms of PET have been used with 5%, 10% and 15% percentages as partial replacement of sand. The result obtained showed that, using PET stripes (PETS) is helpful for some mechanical and physical properties of concrete and suitable for sound absorbent concrete. While, using PET pellets (PETP) in concrete, is found better for erosion resistance against sulfuric acid solution.
