The data collected through questionnaire was analyzed quantitatively using simple descriptive statistics; mean and standard deviation and using inferential statistics, linear regression and ANOVA while quantitative data collected through interview and FDG was analyzed qualitatively using thematic analyses techniques.</p>","doi":"10.20372/nadre:26448","license":{"id":"cc-by"},"publication_date":"2026-10-20","related_identifiers":[{"identifier":"10.20372/nadre:26447","relation":"isVersionOf","scheme":"doi"}],"relations":{"version":[{"count":1,"index":0,"is_last":true,"last_child":{"pid_type":"recid","pid_value":"26448"},"parent":{"pid_type":"recid","pid_value":"26447"}}]},"resource_type":{"subtype":"thesis","title":"Thesis","type":"publication"},"title":"EXAMINING THE ROLE OF SCHOOL COMMUNITY RELATIONSHIP IN  ALLEVIATING BUDGETARY CONSTRAINTS AND ENHANCING FINANCIAL  MANAGEMENT IN SECONDARY SCHOOLS OF ENEBISSIE SAR MIDIR  WOREDA"},"owners":[65],"revision":1,"stats":{},"updated":"2026-10-20T08:28:41.659443+00:00"},{"conceptdoi":"10.20372/nadre:26444","conceptrecid":"26444","created":"2026-10-20T08:26:43.663655+00:00","doi":"10.20372/nadre:26445","files":[{"bucket":"cbd51247-8fe4-4b5f-9674-0c172a630aa4","checksum":"md5:42cf1aeee8f8f268deeb918048903d3a","key":"TEMESGEN BITEW.pdf","links":{"self":"https://nadre.ethernet.edu.et/api/files/cbd51247-8fe4-4b5f-9674-0c172a630aa4/TEMESGEN%20BITEW.pdf"},"size":1336994,"type":"pdf"}],"id":26445,"links":{"badge":"https://nadre.ethernet.edu.et/badge/doi/10.20372/nadre%3A26445.svg","bucket":"https://nadre.ethernet.edu.et/api/files/cbd51247-8fe4-4b5f-9674-0c172a630aa4","conceptbadge":"https://nadre.ethernet.edu.et/badge/doi/10.20372/nadre%3A26444.svg","conceptdoi":"https://doi.org/10.20372/nadre:26444","doi":"https://doi.org/10.20372/nadre:26445","html":"https://nadre.ethernet.edu.et/record/26445","latest":"https://nadre.ethernet.edu.et/api/records/26445","latest_html":"https://nadre.ethernet.edu.et/record/26445","self":"https://nadre.ethernet.edu.et/api/records/26445"},"metadata":{"access_right":"open","access_right_category":"success","communities":[{"id":"debremarkosuniversity"}],"creators":[{"name":"TEMESGEN BITEW"}],"description":"<p>Guanssa River passes through Mertulemariam Town, East Gojjam, Amhara Region, Ethiopia, receives inorganic and organic pollutants from various sources. The objective of this study was to investigate the level of selected heavy metals and physicochemical parameters in Guanssa River water. Some parameters of water were analyzed like pH, electrical conductance and total dissolved solids (TDS) and five heavy metal (Cd, Pb, Cr, Zn and Mn) concentrations using standard procedures. A total of three water samples were collected from different stream of Guanssa River, digested and heavy metal content was analyzed using ICP-OES. The results of the present study have shown that the pH was found to be of range from 6.6 to 8.4 whereas the electrical conductance was 35.1&mu;s/cm to 154.3&mu;s/cm. In addition, the lowest value of TDS was 97.5mg/L and the highest was 190.4 mg/L. The results indicate that the mean concentration of Cd (0.022mg/L), Mn (0.091mg/L), Pb (0.008mg/L), Zn(0.119mg/L) and Cr(0.071mg/L) were found. The result indicates that the concentrations of Cd and Cr are higher than the standard limit that put on WHO for drinking and other domestic activities. This indicates that Guanssa river water is highly polluted by heavy metals.</p>","doi":"10.20372/nadre:26445","keywords":["Heavy metals, Guanssa River, physico-chemical parameter, ICP-OES"],"license":{"id":"cc-by"},"publication_date":"2026-10-20","related_identifiers":[{"identifier":"10.20372/nadre:26444","relation":"isVersionOf","scheme":"doi"}],"relations":{"version":[{"count":1,"index":0,"is_last":true,"last_child":{"pid_type":"recid","pid_value":"26445"},"parent":{"pid_type":"recid","pid_value":"26444"}}]},"resource_type":{"subtype":"thesis","title":"Thesis","type":"publication"},"title":"DETERMINATION THE LEVEL OF HEAVY METALS AND PHYSICO CHEMICAL PARAMETERS OF GUANSSA RIVER FOUND IN  MERTULEMARIAM TOWN, EAST GOJJAM, ETHIOPIA"},"owners":[65],"revision":1,"stats":{},"updated":"2026-10-20T08:26:43.718723+00:00"},{"conceptdoi":"10.20372/nadre:26441","conceptrecid":"26441","created":"2026-10-20T08:24:34.741835+00:00","doi":"10.20372/nadre:26442","files":[{"bucket":"dfb9450b-99ac-4d01-b861-07770b6d58de","checksum":"md5:234f7d4108a60cb0253bd4d5432f229c","key":"SOLOMON JEMBERU BAYIH.pdf","links":{"self":"https://nadre.ethernet.edu.et/api/files/dfb9450b-99ac-4d01-b861-07770b6d58de/SOLOMON%20JEMBERU%20BAYIH.pdf"},"size":1609997,"type":"pdf"}],"id":26442,"links":{"badge":"https://nadre.ethernet.edu.et/badge/doi/10.20372/nadre%3A26442.svg","bucket":"https://nadre.ethernet.edu.et/api/files/dfb9450b-99ac-4d01-b861-07770b6d58de","conceptbadge":"https://nadre.ethernet.edu.et/badge/doi/10.20372/nadre%3A26441.svg","conceptdoi":"https://doi.org/10.20372/nadre:26441","doi":"https://doi.org/10.20372/nadre:26442","html":"https://nadre.ethernet.edu.et/record/26442","latest":"https://nadre.ethernet.edu.et/api/records/26442","latest_html":"https://nadre.ethernet.edu.et/record/26442","self":"https://nadre.ethernet.edu.et/api/records/26442"},"metadata":{"access_right":"open","access_right_category":"success","communities":[{"id":"debremarkosuniversity"}],"creators":[{"name":"SOLOMON JEMBERU BAYIH"}],"description":"<p>Access to safe drinking water is a fundamental human right, yet quality monitoring remains a challenge in rural Ethiopia.
