In seismology, fractal dimensions can be used to describe fractured surfaces quantitatively. The larger the fractal dimension the more rugged is the surface, the more irregular is the line, and the more complex is the pore space. For the present investigation the seismicwave signal of 40 earthquakes including one foreshock, main shock and 38 aftershocks (mb ≥ 5.0) of 2015 Gorkha-Kodari earthquakes from 2015/4/21 to 2016/11/27 were considered. The seismograms were retrieved from the archived waveform data of Incorporated Research Institutions of Seismology (IRIS). The fractal dimension (D) was evaluated by the Python program for box counting. It is found that the fractal dimensions of the seismic wave signal during the active seismic period do not show sudden variation and they are almost identical. The maximum value was noticed to be 1.99±0.006 and the minimum value to be 1.95±0.007. The estimated fractal dimension is greater or equal to 1.95 with an average value of 1.98 which signify the presence of high grade of fractality in seismic wave time series. This suggests that the fractal characteristics of the seismic wave signal of 2015 central Himalayan earthquakes occurrence behavior is nonlinear and coplanar.

The cases of two schools-one from city-located affluent and another sub-urban poor schools were taken to conduct an ethnographic study and cross-validate the findings. The study suggests that the role of the chairperson is more dominant than the head teacher in selected schools. Visionary commitment, devotion, and repeated tenure of chairpersons of the school management committee are the source of school effectiveness, the gradual progress in education quality, and the incremental growth of students. Chairpersons’ performances are boost by their motivation of fulfilling their needs of 'social recognition' and 'experimenting quality education' through school leadership or bringing changes in school; they have already fully filled their physiological needs (Maslow, 1943). Meanwhile, these chairpersons are influenced by the socioeconomic ideology of 'quality education in public schools is the state's accountability for promoting equality and access to the marginalized group'. It also suggests that chairmanship is a process thanthe traits, anyone can lead a school regardless of academic and work experience if guided by an ideology and motivated to fulfill higher level needs.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128994550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mass, number of fall events, types, type mass and mass trend of observed fall meteorites are analyzed over a period of recent century (1922-2021) in this paper. The total number of fall meteorites was found to be 706 with total mass of 42800 kg. Decade 2012-2021 and 1932-1941 had the highest number of recorded fall which was 94 times and 89 times respectively. Type L6 meteorite was found to have the greatest number of falls which is 151 times, followed by type H5 and L5 with 109 times and 55 times respectively. The meteorite of type, Iron III AB had the greatest meteorites mass of 23480 kg followed by H5 and L6 with mass 6615 kg and 2347.362 kg respectively. The massive meteorite fall of this century was of Iron III AB type (1947) which weighed 23 tones. The decade 1942-1951 had the highest fall meteorites mass of 24806kg and 1972-1981 had 4858 kg. Various regression model is fitted for the trend analysis of the mass. Over a period of this century, meteorites having mass greater than 100 kg has struck the earth for 32 times while mass greater than 1000 kg has struck for 6 times. The average time between two impacts of meteorite with mass greater than 100kg was calculated to be 3.12 years while mass greater than 1000 kg was found to be 16.6 years.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114807994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
