Views Of Cognitive Linguistics and The Dynamics of Meaning Descriptive Analytical Study
Get PDFNor is suspicion the same as certainty, The companion of souls is conditional upon you taking them from hidden to clear, and bringing them to them clearly after being hidden, and returning them to one thing, Teaching them to another thing, about which they are more knowledgeable, and their confidence in Him in knowledge is wiser, such as transferring them from reason to sensation, and from what is known by thought to what It is known by necessity and nature, because the knowledge gained from the methods of the senses or focused on them, from the point of view of nature and to the extent of necessity, prefers what is learned from the point of view and thought in terms of strength and precision, and the attainment of complete confidence in it. “News is not the same as neither observation and nor suspicion is the same as certainty,” so this is achieved with this knowledge. This human being, I mean human being in terms of firmness and strength (Abdul Qahir Al-Jarjani Secrets of rhetoric, (pp. 21-22)
The Detection of Brain Cancer Using Machine Learning: A Systematic Analysis of Methodology, Comparisons, Results and Challenges
Get PDFAmong the deadliest illnesses that is not initially recognized in the context of cancer is brain cancer. Cancerous cells are created when cells proliferate quickly and uncontrollably. The changes in tumour location, size, and shape severely impair the ability to detect brain cancers. The wrong diagnosis of a brain tumour can have terrible and fatal consequences. So there is need of high level accuracy to find the tumor classification. The categorization, segmentation, analysis, and detection of brain cancer are the main topics of this work. In order to aid researchers, This study intends to offer an extensive exploration of the existing literature regarding brain tumor identification through the utilization of magnetic resonance imaging. Three different types of medical imaging for brain cancer were subjected to machine learning approaches (feature extraction, augmentation methods, segmentation, and anatomy of brain tumours) and identifies current issues that must be resolved for various machine learning algorithms to be applied widely in the treatment of personalised brain cancer. Ultimately, this comprehensive review compiles relevant scholarly works concerning brain tumor detection, accentuating its advantages, limitations, progressions, and challenges, thus paving the way for potential forthcoming investigations
Coparenting After Divorce: An Approach to Typologies and Context of Intervention
Get PDFCo-parenting after divorce is the relationship of mutual collaboration, support and communication between two parents no longer romantically linked to each other, who work together to raise and care for their children together. Over the past decade, research on co-parenting after divorce has increased. Therefore, the question arises as: what has been published in the last decade on co-parenting after divorce or separation? The aim of this study was to collect, review and synthesize articles published in scientific databases about co-parenting after divorce, to inform about the state of the art on this topic in the last decade to update professionals, academics and researchers who work in the family area, such as social workers, psychologists or lawyers. Thus, a systematic literature review was carried out in seventeen academic databases during August and September 2023. This systematic literature review followed the preferred reporting protocol for systematic reviews and meta-analyses (PRISMA-P) and it was registered in PROSPERO (ID=CRD42022306146). Twenty-nine articles met the inclusion criteria and the quality of each one of them was evaluated with the MMAT instrument. Data were analyzed following the guide for narrative synthesis in systematic reviews. The results show that most of the articles were published during the year 2017, mostly they were from the United States, the type of studies were investigation, with a quantitative design whose participants were fathers and mothers (not dyads). Three recurring themes were identified in the included studies. The three themes were named as: (1) co-parenting categories, (2) components, and (3) interventions. In addition, an integration of the study variables found in the included articles is included and they are organized into four dimensions: positive and negative co-parental relationships, and internal and external factors. It is recommended to regulate through public policies that divorced parents attend interventions or psychoeducational programs as a compulsory stage of the divorce process to promote good co-parenting and prevent conflictive co-parenting relationships
Diagnostic Accuracy of Saliva for Molecular Detection of SARS CoV-2 for Diagnosis of COVID 19: a Comparative Study
Get PDFThroat swab, Nasal swab, Nasopharyngeal swab, Bronchoalveolar lavage fluid and Endotracheal aspirate are the recommended samples by Indian Council of Medical Research for molecular detection of SARS-CoV-2. Saliva specimen is less invasive, can be collected by oneself thus minimizing the risk to the healthcare workers to SARS-CoV-2 exposure. The present study was aimed to evaluate better possible sample collection method among nasal swab, Throat swab and saliva samples of patients for precise COVID-19 diagnosis. A prospective study conducted for diagnosis of COVID-19 samples. three type of samples Nasal and Throat swab and saliva collected for COVID-19 diagnosis. If sample was found positive then Throat and nasal swabs were collected every alternative day while saliva collected every day for COVID-19 diagnosis by RT-PCR. 172 samples of patients were found to be positive for COVID-19. 103 (59.88 %) males and 69 (40.11 %) were females. Throat and Nasal swabs were collected every alternative day. Nasal swab was the best method of sample collection and gave most effective results followed by throat swab in comparison with the saliva sample. Saliva specimen showed positivity only for upto 3 days, while TS and NS specimens showed higher positivity in comparison with saliva specimens for upto 7 days. Further research on usefulness of less invasive saliva specimen is required
An Experimental Study on the Cooling Performance of Refrigerant (R134a/R1234yf) in Automobile HVAC System
Get PDFThe present work deals with the experimental investigation on the performance evaluation of R134a and R1234yf as automotive HVAC refrigerants. As the usage of R134a increases environmental issues due to its higher global warming potential (GWP), it is necessary to find an alternative without compromising the performance of the HVAC system. R1234yf having low GWP is one such drop-in alternative. But the COP of the system using R1234yf is observed to be low. Hence this work investigates on the effects of using an internal heat exchanger (IHX) with the conventional automotive HVAC system in the performance enhancement. The results indicate acceptable range of cooling capacity, COP and compressor discharge temperature for R1234yf when integrated with IHX and a high efficiency evaporator. COP of the R1234yf IHX system is observed to higher than the COP of R134a baseline system. The results of cooling capacity and compression discharge temperature of R1234yf IHX system also shows an enhancement and matches with the corresponding values of R134a baseline system
2D Node-Based Finite Element Method on Linear Accelerator Cavity for Radiation Therapy
Get PDFThis paper deals with the Electromagnetic (EM) field characterization of an S-band Linear Accelerator (LA) Cavity, which is extensively used in cancer treatment. The analysis of the proposed cavity is carried out using an Eigen-mode full-wave EM solver. Mathematical formulation of cavity parameters using the Finite Element Method up to the system of equations is presented. The EM formulization uses a simple 2D square box as segmentation element and also node-based basis functions are used inside the cavity than the edge-based functions. The proposed numerical analysis of a single cavity of LA system is also applicable for a system with multiple numbers of cavities. The cavity has a resonance of 3.0474 GHz and a Q-factor of 17181.6 with finite conducting boundaries at the ends of the drift tube. The nose cone structure in the cavity is essential to have a stronger E-field at the center where the beam passes. Further, the particle acceleration is not constant along the axis of the cavity, which may have severe consequences for beam dynamics. Proper beam dynamics in LA plays a key role in reducing the mortality rate in cancer therapy applications
