Sentiment classification of Roman-Urdu opinions using Naïve Bayesian, Decision Tree and KNN classification techniques

AbstractSentiment mining is a field of text mining to determine the attitude of people about a particular product, topic, politician in newsgroup posts, review sites, comments on facebook posts twitter, etc. There are many issues involved in opinion mining. One important issue is that opinions could be in different languages (English, Urdu, Arabic, etc.). To tackle each language according to its orientation is a challenging task. Most of the research work in sentiment mining has been done in English language. Currently, limited research is being carried out on sentiment classification of other languages like Arabic, Italian, Urdu and Hindi. In this paper, three classification models are used for text classification using Waikato Environment for Knowledge Analysis (WEKA). Opinions written in Roman-Urdu and English are extracted from a blog. These extracted opinions are documented in text files to prepare a training dataset containing 150 positive and 150 negative opinions, as labeled examples. Testing data set is supplied to three different models and the results in each case are analyzed. The results show that Naïve Bayesian outperformed Decision Tree and KNN in terms of more accuracy, precision, recall and F-measure

Wrf-chem simulation for modeling seasonal variations and distributions of aerosol pollutants over the middle east

Atmospheric aerosols and dust have become a challenge for urban air quality. The pre-sented study quantified seasonal spatio-temporal variations of aerosols, tropospheric ozone, and dust over the Middle East (ME) for the year 2012 by using the HTAP emission inventory in the WRF-Chem model. Simulated gaseous pollutants, aerosols and dust were evaluated against satellite measurements and reanalysis datasets. Meteorological parameters, temperature, and wind vector were evaluated against MERRA2. The model showed high spatio-temporal variability in meteorological parameters during summer and low variability in winter. The correlation coefficients for all the parameters are estimated to be 0.92, 0.93, 0.98, and 0.89 for January, April, July, and October respectively, indicating that the WRF-Chem model reproduced results very well. Simulated monthly mean AOD values were maximum in July (1.0–1.5) and minimum in January (0.1–0.4) while April and October were in the range of 0.6–1.0 and 0.3–0.7 respectively. Simulated dust concentrations were high in April and July. The monthly average aerosol concentration was highest over Bahrain, Kuwait, Qatar, and the United Arab Emirates and Jeddah, Makkah. The contributions to urban air pollution were highest over Makkah city with more than 25% from anthropogenic sources

Electron emission characterization of laser-induced gaseous plasma

Laser induced hydrogen plasma has been investigated as a source of electrons. The energy, temperature and flux of the electrons have been determined by using two different temporal detectors; Faraday cup and Rogowski coil. The energy, temperature and flux were measured from the electrons extracted from laser induced hydrogen plasma. The Rogowski coil has been used for measurement of flux and current whereas Faraday cup has been used to determine the current density in laser induced plasma. The energy and temperature of the electrons are measured by the time of flight method in the range of 1.23 - 5.04 keV and 2516.26 eV, respectively. The flux of the electrons has been measured ≈ 1015 by Rogowski coil and the maximum current has been measured to be 39.6 kA. The current density has been measured by the Faraday cup ranges from 20 Am-2 to 23 Am-2

Lípidos totales y perfil de ácidos grasos de hígado de pescado Catla catla salvajes y criados

This experimental work was aimed to study the moisture content, total lipids and fatty acid profile in the liver of wild and farmed freshwater major carp Catla catla of three different weight categories designated as W1 (601-900g), W2 (901- 1200)g and W3 (1201-1500g). Seven fish specimens of each of the three weight categories of wild and farmed Catla catla were obtained from Trimu Head, Jhang and Fish Hatchery, Satiana Road and Faisalabad, respectively. The fish were dissected to remove the liver and after weighing, liver samples were prepared and subjected to chemical analysis. Wild Catla catla liver had a significantly (p < 0.05) higher moisture content as compared to the farmed species. Farmed Catla catla deposited significantly (p < 0.05) higher lipid contents in liver. Proportions of saturated fatty acids varied irregularly in the lipids of the liver from both wild and farmed Catla catla. Saturated fatty acids C12:0, C14:0, C16:0, C18:0, C20:0 and C22:0 were identified with considerable percentages in the liver of Catla catla from both habitats and monounsaturated fatty acid C18:1 was found in considerable amounts in the liver of both major carp. Polyunsaturated fatty acids such as C18:3 (n-6) and C20: 2 (n-6) were detected in the liver of the wild fish of W2 and W3 and was similar in the W3 weight category of the farmed species.Este trabajo experimental tiene como objetivo estudiar el contenido de humedad, lípidos totales y perfil de ácidos grasos de hígado de carpa de agua dulce Catla catla de tres categorías con peso diferentes designadas como W1 (601- 900g), W2 (901-1200)g and W3 (1201-1500g). Siete muestras de pescados por cada una de las tres categorías de peso para Catla catla salvajes y criados fueron obtenidos de Trimu Head, Jhang and Fish Hatchery, Satiana Road y Faisalabad, respectivamente. Los pescados fueron diseccionados para obtener el hígado y las muestras de hígado fueron preparadas y sujetas a análisis químico. Catla catla salvaje tuvo un contenido de humedad significativamente mayor (p < 0.05) en comparación con las especies criadas. En Catla catla criadas se depositaron mayores contenidos de lípidos en el hígado. La proporción de ácidos grasos saturados vario irregularmente en los lípidos del hígado de Catla catla salvajes y criados. Los ácidos grasos saturados C12:0, C14:0, C16:0, C18:0, C20:0 y C22:0 fueron identificados en un alto porcentaje en hígados de Catla catla procedentes de ambos hábitat y el ácido graso monoinsaturado C18:1 fue encontrado en una cantidad considerable en el hígado de ambas carpas. Los ácidos grasos poliinsaturados tales como C18:3 (n-6) y C20: 2 (n-6) fueron detectados en el hígado de pescados salvajes W2 y W3, así como en la misma categoría de peso W3 de especies criadas

Efecto del grado de maduración en el perfil de ácidos grasos de diferentes tejidos de rohu (Labeo rohita) salvaje y criado

During the breeding season, lots of physiological changes occur in the bodies of fish which lead to other phenotypical, anatomical and behavioral changes. To evaluate the impact of breeding on the bodily composition of fish, tests were conducted to determine the fatty acid profile of the brooder and Non-brooder wild and farmed fish. Samples were analyzed by gas liquid chromatography using a flame ionization detector.There are non significant differences in the amount of saturated and unsaturated fatty acids in wild and farmed nonbrooder fish whereas in case of brooder there are significant differences. Brooder farmed fish contained more saturates in gonads approximately twice that of wild fish with C16:0 as the dominating fatty acid. C18:2n-6 and C20:5n-6 were the dominating unsaturated fatty acids in the gonads. Non-brooder fish contained more unsaturated fatty acids in the meat as compared to the brooder fish and farmed fish contained higher amounts of saturated fatty acids as compared to wild fish. C18:1n-9 and C20:4n-6 fatty acids were found in higher quantities and among the saturated acids, C16:0 is the dominating one. More or less similar results were found in the case of the liver fatty acid profile of breeding and nonbreeding fish. Fish of lower weight categories contained more unsaturated fatty acids and so better for consumption to leave the brooders of higher weight categories for the breeding of future generation.Durante la época de reproducción numerosos cambios fisiológicos ocurren en el cuerpo de los peces que guían a cambios anatómicos y de comportamiento. Para evaluar el impacto de la etapa de reproducción en la composición de los peces, ensayos para determinar el perfil de ácidos grasos fueron conducidos en peces salvajes y criados, en dos categorías de peso, maduro (booder) o inmaduro (non-brooder). Las muestras fueron analizadas por cromatografía de gases usando un detector de ionización de llama. No hubo diferencias significativas en la cantidad de ácidos grasos saturados e insaturados en peces salvajes o criados non-brooder mientras que en el caso de los brooder sí hubo diferencias significativas. Los peces brooder criados contienen más ácidos grasos saturados; en gónadas aproximadamente el doble que los salvajes con el C16:0 como el ácido graso dominante. C18:2n-6 y C20:5n-6 fueron los ácidos grasos insaturados dominantes en las gónadas. Los peces non-brooder contienen más ácidos grasos insaturados en la carne que los peces brooder y los peces criados contienen mayores cantidades de ácidos grasos saturados en comparación con los peces salvajes. Los ácidos grasos C18:1n-9 y C20:4n-6 fueron encontrados en cantidades más altas y entres los saturados el C16:0 fue uno de los principales. Resultados más o menos similares fueron encontrados en el caso del perfil de ácidos grasos de hígados de peces en etapas de reproducción y no reproducción. Los peces de la categoría de pesos más bajos contienen más ácidos grasos insaturados y son mejores para el consumo y permite la cría de peces de peso más alto

Comorbidity of COVID-19 related Fatalities in Tertiary Care Hospitals of Rawalpindi, Pakistan

Objectives: To assess the COVID-19 associated fatalities with respect to demographics, comorbidity, critical illness, and length of hospital stay in tertiary care hospitals. Subjects &amp; Methods: A retrospective hospital data-based research was done among 216 COVID-19 associated mortalities registered in 4 tertiary care hospitals Holy Family Hospital (HFH), Benazir Bhutto Hospital (BBH), District Head Quarters Hospital (DHQ) and Rawalpindi Institute of Urology &amp; Transplantation (RIU &amp; T) affiliated with Rawalpindi Medical University from 29th March-15th June 2020. The data was gathered by consecutive sampling pertinent to demographics, hospital stay, comorbidity, critical illness, and ventilator or oxygen support. The length of hospital stay among fatalities with and without comorbidity was compared by an independent sample z-test. Data were analyzed by using SPSS version 25.0. Results: Of the total 216 COVID-19 related mortalities, 150(69.4%) were males and 66(30.6%) were females. The mean age of fatalities was 55.66 ± 13.97 years. About 76.7% of dying males were 41-70 years old while 56.1% of females dying of COVID-19 were 41-60 years old. Most (60.8%) of study subjects had hypertension followed by diabetes (53.8%), Ischemic Heart Disease (17.5%), and respiratory disorders (12.3%). About 75% of the critically ill patients needed a ventilator for respiratory support. Length of hospital stay was determined to have a statistically insignificant association (P &gt; 0.10) with the presence or absence of comorbidity among COVID-19 patients. Critical illness had a highly significant association (P &lt; 0.000) with ventilator support among COVID-19 related mortalities. Conclusion: People 41-70 years should preferably adopt stringent precautions for protection against COVID-19. Comorbid states chiefly hypertension, diabetes, cardiac and respiratory diseases need special consideration amid COVID-19 pandemic to abstain from adverse health outcomes

An assessment of social, economic and managemental factors affecting average production per week in commercial layers at district Toba Tek Singh, Punjab, Pakistan

Background: The research was conducted to identify social, economic and management factors that may affect the total egg production in terms of total number of weak for average peak production in layers at district Toba Tek Singh.Methods: Sampling method was based on primary data collected through survey. Twenty-five layer farms were selected randomly with three different types of production systems (viz., open sided litter floor system, Semi controlled cage system and semi controlled litter floor system). Farmers were visited personally and interviewed. The data were analyzed by MINITAB-17 using multiple regression analysis.Results: Result showed that 12% of the respondents are under the age of 25 years, 80% fall between the age of 25-50 years, 8% fall more than the age of 50 and above. Study showed that more than 50% farmers are having qualification above secondary level i.e., 48 % are within the range of higher secondary and graduation, while 4% are specialized in animal production and health (veterinarian). Majority of the farmers had a farm size less than a capacity of 25000 birds, while only 16% farmers had a farm size with a capacity of above 50000 birds. The House type, Birds at first lay, Age at data recording, Age at first egg and Feed cost were significant (P≤0.01). However, demographic variables were non-significant at all levels of probability. The results showed that the economic and management factors of farmers have significant effect on average peak production of layers kept by them.Conclusion: The importance of the economic and management factors, concluded significant influence made by the social, economic and management factors on poultry egg production.Keywords: Social; Economic; Management; Peak production; Layer
