Objective: To explore the relationship between the liver T2* values of thalassemia patients measured by Circle Cardiovascular Imaging CVI42 (CVI42), CMRtools / Thalassemia Tools (CMRtools) and Excel spreadsheet (Excel), and the three software's accuracy in clinical grading of liver iron concentration (LIC). Methods: The liver T2* images thalassemia patients were imported into CVI42 and CMRtools to measure the T2* value. And the signal intensity (SI) of the T2* image, measured in the MR scanning equipment, was input into Excel to calculate T2* value. The relationship of the T2* values measured by the above three software were compared. And LIC clinical grading was performed on the three measured T2* value results, and the LIC (LICF) provided by FerriScan was used as the reference standard to compare the accuracy of the three grading results. Results: There was no statistical difference between the T2* values measured by CVI42, CMRtools and Excel (P>0.05), but there was a high degree of consistency between them (P<0.05), and there was a high linear positive correlation between the them (P<0.05). There was no statistical difference between the LIC grading results of CVI42 and CMRtools and the LICF grading results (P>0.05). There is a significant difference between the LIC grading results of Excel and the LICF grading results (P<0.05). Conclusion: The liver T2* values measured by CVI42, CMRtools and Excel are equivalent. However, CVI42 and CMRtools have better diagnostic accuracy for LIC clinical grade, while Excel has worse diagnostic accuracy.

An Efficient Clustering Technique for Big Data Mining
Authors: Banait Satish S. , SANE Dr. S. S. 
Published: October 2022

Data mining and big data analytics are approaches for analyzing data and extracting hidden information. Because big data is complicated and large in volume, traditional techniques to analysis and extraction do not function effectively. Data clustering is a common data mining approach that divides data into groups and makes it simple to extract information from them. Big data can include both organized and semi structured information, and it's becoming increasingly beneficial for companies. Examples include old organized database of inventory level, transactions, and consumer information, as well as non - structured comprehension from the internet, social media platforms, and embedded systems. Numerous schemes have been developed to reach the needed in relation to efficiency and effectiveness, and much study has been committed to Big Data analytics. Nevertheless, a few methodologies, such as clustering algorithms, require further research in regards to performance, usefulness, and other factors, leading to the development of a model which gives proper Big Data Analytics assessment and the impactful use of this methodology to retrieve relevant knowledge. We recorded and analyzed several big data sets in our proposed work, as well as discovered relevant current approaches. In this paper we proposed a new clustering technique using dimensionality reduction approach. For implementation of this work, we used real time streaming data in unstructured form and noisy sometimes. The proposed hybrid clustering techniques that improve the clustering accuracy as well as time for generate effectives clusters on large unstructured data. We confirm the findings by testing the suggested methodology on available information sets and comparing and analyzing the effectiveness of the developed system with that of current systems.

El objetivo general de esta investigación es determinar el impacto de las enfermedades profesionales en el desempeño laboral de los colaboradores en 9 empresas de limpieza las cuales corresponden a 3 por Cantón y con un número mayor a 50 colaboradores. Debido al alto riesgo de estas empresas, nos planteamos el objetivo en mención de estas empresas de en Manta, Montecristi y Jaramijó, para cumplir con las normativas vigentes en cuanto a seguridad y salud ocupacional, que les permita a las empresas objetos de estudios la identificación y prevención de enfermedades.

Se realizó una búsqueda y revisión bibliográfica de los últimos 5 años, utilizando una metodología de investigación de tipo descriptiva – analítica, con un enfoque cuantitativo y cualitativo. Mediante encuestas, observaciones y entrevistas.
Según el estudio realizado evidenciamos que la gestión de seguridad y salud dentro de las empresas es muy baja, debido a que las empresas solo cuentan con un reglamento de Seguridad con la finalidad de cumplir un requisito más ante la Ley como lo pide el Código de trabajo y el Ministerio de relaciones laborales, pero no se está realizando la gestión necesaria para identificar y prevenir los riesgos que pueden afectar a su personal.
Se concluye que estos colaboradores no poseen conocimientos acerca de un reglamento de seguridad y salud ocupacional, y que no tienen revisiones periódicas de un médico tal como lo indican las leyes parar las empresas que cuentan con más de 50 empleados.

Published: October 2022

Introduction: Perforated sinus of Valsalva is a rare congenital defect; the natural history is not well defined, if left untreated, the prognosis is poor. It has been shown that conventional surgical repair of perforated sinus of Valsalva carries low morbidity and mortality. However, transcatheter closure of perforated sinus of Valsalva is a minimally invasive treatment method, avoiding the complications of anesthesia and postoperative surgery for the patient, while still ensuring effectiveness and low complication rate. [1]
Method: based on a clinical case at Cardiovascular Center- Hospital E and a review of the literature, the report aims to describe the risk factors, early diagnosis methods and appropriate management solutions for these lesions.
Case summary: A 34-year-old female admitted to the hospital because of shortness of breath and fatigue. The medical history was normal. Echocardiography detected: ruptured aneurysm of Valsalva sinus into the right atrium. The patient received transcatheter closure of perforated the sinus of Valsalva into the right atrium. The patient was then discharged from the hospital in a stable condition.
Conclusion: Valsalva sinus aneurysm rupture is a rare injury, if left untreated, will affect your health. Transcatheter closure of perforated the sinus of Valsalva is a suitable alternative to surgical repair that is still effective.

Convective Flow of Radiative Maxwell Nanofluid with Variable Thermo-Physical Properties
Authors: Borgohain Debozani 
Published: October 2022

In this article, analysis has been executed to find the impact of radiation, varied thermal conductivity and varied viscosity on the steady 2 dimensional flows of nanoparticles existing Maxwell fluid past a flat surface that can be stretched. The partial differential equations which govern this flow are modified by using similarity transformations in order to form ordinary differential equations. Employing bvp4c of MATLAB software the transformed equations are solved and the results for velocity, temperature and species concentration are depicted through graphs for varying parametric values. Comparisons with previous published data of analytical methods are carried out, thereby validating the present numerical results. It has been observed that thermal conductivity as well as viscosity enhances the temperature of the fluid and nanoparticles species concentration. Also the nanoparticles existence in the fluid slows down the fluid motion. In various engineering processes and nanoscience technology, the inferences of this present study can find its applications.
HIGHLIGHTS

Investigation has been carried out on a 2 dimensional steady flow of upper-convected Maxwell fluid under the existence of the radiation and nanoparticles
The thermo-physical properties of the fluid flow such as thermal conductivity and viscosity are taken as variable quantity
Bvp4c solver of the software MATLAB has been used to solve the governing transformed ODEs
With the rise in thermal conductivity and fluid viscosity, the temperature of the fluid boost up
The existence of nanoparticles in the fluid results in deceleration of the fluid motion
Assessment of Health Risks to People in Northeastern Thailand from the Intake of Sodium and Synthetic Preservatives Contained in Traditional Thai Fermented Fish Sauce (Nam-Pla-Ra) and Their Pathogenic Prevalence
Authors: Hirunsorn Pimnibha , Isnainia Mutiara Nur 
Published: October 2022

This research aims to assess the health risks in Thailand from sodium and synthetic preservatives in traditional Thai fermented fish sauce (nam-pla-ra) and their pathogenic prevalence. Of 54 pasteurized-bottles and 37 bottles of Thai Papaya salad (somtum) sold by street vendors, the ingredients containing preservatives were found to be 63 (70 %) comprising 67 % (in bottles) and 53 % (of somtum ingredients) of different types, concentrations, for single or combined use. These preservatives analyzed by high performance liquid chromatography (HPLC) method did not comply with Thai Community Product Standards for traditional Thai nam-pla-ra. The estimated daily intake of sorbic and benzoic acid is below that of the ADIs (Acceptable Daily Intake) in all cases as the amounts were 0.11 - 3.25 % for benzoic acid and 0.00 - 0.01 % for sorbic acid. The sodium risk was estimated as 46.9 - 81.7 % affecting people aged 35 years old to the elderly (≥ 65 years) in pasteurized-bottles (81.7 %) and somtum ingredients (70.3 %). The pathogenic and sanitary indicators of microbes in nam-pla-ra obtained from somtum vendors need to be improved by educating the somtum nam-pla-ra vendors in hygienic standards. The scientific data in this work can provide a proper guide to suitable amounts of intake leading to more effective government regulations for nam-pla-ra or related products.
HIGHLIGHTS

Synthetic preservatives and sodium critically assessed, and risks identified
70 % of products not per Thai Community Product Standards and 7 % not per FDA regulations
Thai population not at risk of exceeding ADIs for preservative and sodium intake
6 % of various nam-pla-ra brands (54) had no/incorrect preservative declaration
aureus, E. coli, C. perfringens, Salmonella spp. over standard (street vendors)
