Predicting Students' Degree Completion Using Decision Trees

Educational Data Mining (EDM) helped institutions to improve students' performance by predicting student's future learning behavior. To benefit from this, the researchers conducted this study to predict the successful degree completion and provide early intervention as necessary. Decision Tree algorithm provided by WEKA is used to build the model using students' data such as Entrance Exam Results, gender, school type where they graduated high school and final grades from English 1, Algebra and major subjects. Students who entered the University from school years 2012-2013, 2013-2014, 2014-2015 and 2015-2016 were selected. RandomForest suited best for the model and desktop application was designed and evaluated as Outstanding in terms of Efficiency, Accuracy and User Friendliness.

ELECTRODE POTENTIAL OF STEEL 10Х23Н18

Most welded structures operate under difficult conditions of simultaneous exposure to corrosive media and workloads. Practice shows that the destruction of welded structures under such operating conditions occurs, as a rule, along a weld seam or a zone of thermal influence. The aim of the work is to study the coil of the pyrolysis furnace and the corrosion characteristics of 10Х23Н18 pipe steel by measuring electrode potentials

Depression and sex hormones in elderly women

We aimed to study the relation between sex hormones and depression among elderly women. The study was carried out on 74 volunteered female subjects above 60 years of age. Each subject was asked to fulfill the geriatric depression scale (GDS) questionnaire and further evaluated for clinical depression by a psychiatrist using the DSM IV diagnostic criteria. For statistical analysis, subjects were later divided in two groups, according to the presence of clinical depression. Cognitive functions were assessed with the standardized mini mental test (SMMT). Disability in the activities of daily living was assessed with instrumental activities of daily living (IADL) scale. Plasma levels of estrogen, testosterone, progesterone, and dehydroepiandrosterone sulfate (DHEA-S) were measured with chemiluminescent methods, and plasma levels of androstenedione were measured with radioimmunassay. Among 74 subjects, 34 (39%) had clinical depression. Age, number of years spent in education, SMMT scores, and IADL scores did not differ between the depressive and non-depressive groups. Plasma sex hormone levels were not found to be different between the two groups. (C) 2004 Elsevier Ireland Ltd. All rights reserved

Recording Ion Channels in Isolated, Split-Opened Tubules

Ion channels play key roles in physiology. They function as protein transducers able to transform stimuli and chemical gradients into electrical signals. They also are critical for cell signaling and play a particularly important role in epithelial transport acting as gateways for the movement of electrolytes across epithelial cell membranes. Experimental limitations, though, have hampered the recording of ion channel activity in many types of tissue. This has slowed progress in understanding the cellular and physiological function of these channels with most function inferred from in vitro systems and cell culture models. In many cases, such inferences have clouded rather than clarified the picture. Here, we describe a contemporary method for isolating and patch-clamping renal tubules for ex vivo analysis of ion channel function in native tissue. Focus is placed on quantifying the activity of the epithelial Na(+) channel (ENaC) in the aldosterone-sensitive distal nephron (ASDN). This isolated, split-open tubule preparation enables recording of renal ion channels in the close to native environment under the control of native cell signaling pathways and receptors. When combined with complementary measurements of organ and system function, and contemporary molecular genetics and pharmacology used to manipulate function and regulation, patch-clamping renal channels in the isolated, split-open tubule enables understanding to emerge about the physiological function of these key proteins from the molecule to the whole animal

Stressors of Criminology students in University of Mindanao

In Partial Fulfillment of the Requirements for the Degree of Bachelor of Science in CriminologyStress has turned into a developing issue for college students as they attempt to adapt to academics, social, and individual difficulties. The study was bent on determining the stressors of criminology students in University of Mindanao. The study utilized descriptive survey and used Mean, ANOVA and T-test as the statistical tools of the study. The result of the study are presented as follows: The respondents of this study were 200 criminology students in University of Mindanao, which is equivalent to 100 percent. The level of Stressor factors of Criminology students in University of Mindanao is average. There is significant difference on the stressors of criminology students in University of Mindanao when analyzed by gender. There is significant difference on the stressors of criminology students in University of Mindanao when analyzed by year level.TPS-UDT36 leave
