Effectiveness of three different rotary systems in removing gutta percha from root canals
Get PDFBackground: The present study was conducted for comparing the effectiveness of three different Rotary systems in removing gutta percha from root canals. Materials & methods: 30 single rooted freshly extracted, mandibular premolars were collected and stored in 10% formalin until further use. Crowns of selected teeth were decoronated using diamond disc to standardize the working length to 16 mm for each specimen. Access preparation was done on each tooth and a size 10 K-type file was inserted into the canal until it was visible at the apical foramen to ensure that the canal was patent. Afterwards, all the specimens were randomly divided into three study groups according to type of retreatment system. Group A: ProTaper Universal retreatment Ni–Ti rotary instrumentation system, Group B: Mtwo retreatment Ni–Ti rotary instrumentation system, and Group C: R-Endo Ni–Ti rotary instrumentation system. After tooth splitting, each half of every specimen was separately imaged. Digitized images of each third of the root canal of each half of every specimen were obtained and evaluated.

Secondary school dropout in Kabawa community in Kebbi State, Nigeria
Get PDFThe prevalence of dropouts in educational institutions especially in secondary schools affected the integrity of the system. It is important to note that, every country invest in its youths because they are the country’s future human resources, among them will emerge leaders in politics, academics, technology, and business of various dimension. This paper attempted to identify the factors that influence school dropout and the consequences that would result. The paper identifies the following as some of the factors that would influence the secondary dropout all over the globe and Kebbi State in particular. The investigation indicated that the problems of dropouts are far more nuanced than its apparent cause would suggest. In the state of Kebbi, there are a number of factors that contribute to students dropping out of secondary school such as kidnapping students for ransom, banditry, thuggery, insurgent activities, general insecurity, cultism, parents' divorce, minority in language/ethnicity differences, physical disability as well as poverty, lack of government support, illiterate parents/family background, “I don’t care”/indifferent attitude in community, drug abuse, unwanted pregnancy, early child marriage and etc. These are among several factors contributing to students dropping out of school. 
An emotional intelligence relationship with academic achievement: An Islamic secondary school student context
Get PDFThis study is about the investigation of Form One Islamic High School students emotional intelligence at Hulu Terengganu district in Malaysia. 364 Form One students was selected from 4 Islamic high school in the district to answer the questionaires. The data of frequency, percentage, mean and standard deviation was run and analyzed using Statistical Package for Social Science (SPSS version 20.0). Research outcome showed that the students’ emotional intelligence level is in the medium range, which interpersonal skill is the most dominant domain among the students. Its shows have a relationship between the emotional intelligence and the students’ academic achievement through the Pearson correlation analysis. But the relationship is not significant. 
Quality of life of stroke’s patient: Systematic literature review
Get PDFStroke is a prevalent issue within the community as the diagnosis of stroke plays an essential role in the Quality of life (QoL) of the patient. This study is a Systematic Literature Review (SLR) of QoL of stroke patients according to the statement of Preferred Reporting Items for Systematic Review (PRISMA). A published article between 2008 to 2020 from four databases namely EBSCO Medline, Ovid, PubMed and Science Direct were included in the study. After the identification and screening process, 37 articles were reviewed thoroughly in the study. Analysis of these 37 articles revealed the QoL of stroke patients is poor compared to the general population. The diagnosis of stroke impacted both physical and mental dimension of QoL in which the most impacted domain was reported to be the physical domain. Among the influential factors towards QoL were age, patient’s disability, gender, patient’s comorbidity, income status and family support. To improve the QoL of the patients, it’s highly imperative to consider the factors influencing QoL in the treatment plan of the patients. 
Design of an improved soft computing model for EEG classification using MFCC and quad classifier
Get PDFElectroencephalography (EEG) signals are a combination of complex pattern sequences,that are periodic in nature. These pattern sequences include a gamma waves that indicates deep thinking behaviour, a beta wave sequence that indicates busy and active mind status, an alpha wave segment which indicates reflective and restful behaviour, a theta wave which is an indicative of drowsiness, and a delta wave which indicates sleeping & dreaming conditions. Features like frequency changes, amplitude changes, pattern changes, etc. are used to identify chronic, ischemic and other diseases related to the brain. In order to classify these wave patterns into brain diseases like epilepsy, a series of high complexity signal processing operations are needed to be executed in tandem. These operations include signal pre-processing, feature extraction, feature selection, classification into epileptic & non-epileptic seizure and post-processing.A large variety of algorithms are developed by researchers for each of these operations. Performance of these algorithms varies largely w.r.t. the number of leads used for EEG capture, filtering efficiency, feature extraction & selection efficiency, and classifier efficiency.Thus, it becomes ambiguous for researchers and system designers to select the best possible algorithm set for their application. the proposed AMVAFEx model uses Multiple Neural Networks for definite EEG grouping.
 
Preventive effects of garlic powder on cisplatin-induced nephrotoxicity in male wister rats
Get PDFCisplatin is cancer chemotherapeutic agent that used in treatment of many types of solid cancers. However, cisplatin administration showed adverse effects including multi-organs toxicity including nephrotoxicity. Garlic is an anti-carcinogenic, antioxidant, anti-diabetic, Reno protective, anti-atherosclerotic, antibacterial, antifungal, and antihypertensive agent. Therefore, present study was conducted to investigate preventive effect of garlic powder on Cisplatin induced nephrotoxicity in male Wister rats. Twenty-one male Wister rats were assigned into three groups namely, C (as control negative group), CP (control positive) received two i.p injection of cisplatin at dose of 8 mg/kg and G-CP received two i.p injection of cisplatin at dose of 8 mg/kg and fed with 10% garlic powder diet. Serum samples were collected and kidney function parameters including creatinine, urea and uric acid levels were measured using colorimetric kits for these parameters. creatinine results showed a significant increasing in CP group rats compared with G-CP group. Urea results showed a significant increasing in CP group rats compared with G-CP group. Also, uric acid results showed a significant increasing in CP group rats compared with G-CP group. In conclusion, rats that fed with 10% garlic powder diet reduced nephrotoxicity that induced by Cisplatin

Improving the thermal efficiency of the heat pipe using a heterogeneous polyethylene fibre wick system
Get PDFThermal engineers face a lot of challenges in converting heat with low heat dissipation rate. This idea led me to read and analyse the heat pipe in various forms. “Heat pipes” are used in various mechanical and electronic devices. A small improvement in the “heat pipe design” will result in a drastic change. Can reduce the heat dissipation rate. Many factors affect the “efficiency of the heat pipe”. This includes the geometric design, the number of evaporators and capacitors, the working liquid characters, the application of different coatings, the adhesive and the combined forces. A “wick system model” can be created in CATIA (a 3D modelling software). Different heat transfer properties can be determined using “CFD analysis” by changing different types of wick materials. CFD analysis will analyse the best and most effective material with pressure drop, “heat transfer rate and temperature variation” with measured values
Telemedicine: A new tool for transforming fututre healthcare
Get PDFTelemedicine is the solution to the problem of delivery of health services in far fledge areas. It is the use of computers and automated data to deliver technologies and promote healthcare when the patients are located far away from the professionals. Its future looks bright with more widespread acceptance by more medical professionals and patients in different forms. There has to be a smart balance between technology and the human intelligence. However, telemedicine cannot be the panacea and surely cannot replace old fashioned medicine everywhere especially emergency medicine. More measures are required to make this change more successful and acceptable
