Magnetocaloric effect in itinerant electron metamagnetic systems La(Fe1-xCox)11.9Si1.1

The NaZn13-type compounds La(Fe1–xCox)11.9Si1.1 (x=0.04, 0.06, 0.08) were successfully synthesized, in which the Si content is the limit that can be reached by arc-melting technique. TC is tunable from 243 to 301 K with Co doping from x=0.04 to 0.08. Great magnetic entropy change S in a wide temperature range from ~230 to ~320 K has been observed. The adiabatic temperature change Tad upon changing magnetic field was also directly measured. Tad of sample x=0.06 reaches ~2.4 K upon a field change from 0 to 1.1 T. The temperature hysteresis upon phase transition is small, ~1 K, for all samples. The influence of Co doping on itinerant electron metamagnetic transition and magnetic entropy change is discussed. ©2005 American Institute of Physics.published_or_final_versio

Knowledge on the risk and practices on self-diagnosis and self-medication form common colds

This study utilized a descriptive correlational research design. Snowball sampling technique was used in the study. Barangay Timalan Balsahan have a total population of 646 and Barangay San Roque have a total population of 155. The overall population is 801 and the sample size obtained is 400. This study used a three-part self-made questionnaire that determines the knowledge on the risk and practices on self-diagnosis and self-medication for common colds. The data gathered were subjected to statistical treatments such as frequency distribution, percentage, mean, standard deviation, t-test, Pearson’s r, F-test or analysis of variance (ANOVA) and Duncan’s multiple range tests. Based on the findings of the study, the following conclusions were drawn: 1) Majority of the respondents were 29 years old and below, high school graduate, have a monthly family income of 10,000php, and belonged to the nuclear family type; 2) The respondents have an overall average knowledge on the risk of self-diagnosis and self-medication for common colds. Likewise, the majority of the respondents belonged to the average knowledge on the risk of self-diagnosis and self-medication; 3) The respondents have an overall moderate practice on self-diagnosis and self-medication for common colds. Likewise, majority of the respondents have a moderate level of practice on self-diagnosis and self-medication for common colds; 4) There were no significant differences in knowledge of the respondents on the risk of self-diagnosis and self –medication for common colds when groups according to age, educational attainment, monthly family income and type of family; 5) There was no significant difference in the practices of the respondents on the risk of self-diagnosis and self –medication for common colds when groups according to age. However, there were significant differences in the practices of the respondents with regards to self-diagnosis and self –medication for common colds when groups according to educational attainment, monthly family income, and type of family. Considering DMRT, respondents who graduated from college significantly have a better practice when compared to respondents who graduated elementary and high school. On the other hand, respondents belonged to the nuclear family, extended family and blended family significantly have a better practice when compared to respondents who belong a never married family; 6) There was no significant relationship between the knowledge of the respondent on the risk and practices on self-diagnosis and self-medication for common colds
