Methods: Wistar rats were anemic with phenylhydrazine for two days. From D2 to D15, some were treated by gavage with the butanolic fraction of the aqueous extract of Cocos nucifera roots at the dose of 40 mg or 60 mg / kg of body weight / day, others were treated with vitafer (an anti-anemic drug) or with distilled water.

Before being managed by the University of Brawijaya, there was a change in land cover from natural forest to pine and mahogany production forest. This change was a result of the PHBM (Collaborative Forest Management) contract agreement between Perhutani and the community to carry out agricultural management. The input of organic matter with different quality and quantity will affect the organic matter content and in turn will affect the physical properties of the soil such as bulk density, density and soil porosity. Soil porosity is a physical property of soil that affects soil infiltration. The objective of this study is to identify and analyze the management of Forest Areas and to build a green economy model in the management of KHDTK University of Brawijaya Forest in the Perspective of Sustainable Development Goals (SDGs) in Malang Regency. The method used in this research is qualitative research. Implementation of green economy model in the management of KHDTK University of Brawijaya Forest in the concept of forestry sector contribution related to climate change; the concept of sustainable forest resource management; and the concept of environmental service providers. The results of the infiltration measurement using the single ring infiltrometer method can better describe the infiltration that occurs in the soil. The highest soil infiltration is in protected areas with a soil infiltration rate of 131.33 cm/hour (single ring infiltrometer). Meanwhile, the lowest infiltration was found in the pine production forest plot overlaid with seasonal crops with a soil infiltration rate of 12 cm/hour (single ring infiltrometer).","PeriodicalId":13849,"journal":{"name":"International Journal of Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78282991","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}

These students had to prepare for the continuity of their study mentally and physically by adapting to the online teaching and learning approach, which can significantly impact their academic performance. Hence, this study examines the students’ academic performance on the online teaching and learning approach, thus predicting their academic performance for the upcoming semester. This study enables various actions to be taken in improving and maintaining the student’s performance in their study activities. The study was conducted on undergraduate students from the Faculty of Science and Mathematics, Universiti Pendidikan Sultan Idris. This paper presents the prediction of the student’s academic performance with a linear regression model. Evidently, the result shows that the student’s academic performance continually improves while adapting to the online teaching and learning approach. It also shows that there were few respondents affected while adapting to this new norm approach. Hence, the future development of the regression model can be improved by having a more comprehensive range of Malaysian universities’ data. © 2021 North Atlantic University Union NAUN.

This study aims to observe, study and find events related to the focus of research to get the formulation of a model of green leadership in the management of natural resources and the sustainable environment that appears naturally. The results of this research found that the Green Leadership Model’s has the criteria : has an understanding of environmental issues, response to policies, community accessibility, institutional support, commitment to environmental sustainability, has innovation that is pro to the environment and an optimal role for leaders in the management of natural resources and sustainable environment. These included the following; in the past experience, sustainable management of natural resources and the environment around the Meratus mountains is strongly influenced by the leadership role both formally and informally. Sustainability of natural resource management and sustainable environment is strongly influenced by leadership who: has awareness and love for the environment, provide motivation through direct implementation to the community through policies that are implemented in maintaining environmental sustainability, provide broad access for the community to participate in the management of natural resources and the environment which experiences a lot of quality degradation ; firm and able to refuse in responding to the demands of the business world which focus on increasing profits alone to exploit natural resources and the environment; and has criteria as an environmentally friendly leadership model in accordance with the criteria needed as an ideal description of leadership. Green leadership models in the management of natural resources and the environment come from formal and informal leadership. The formal green leadership comes from the Regional / Institution / Institution of government, while the informal green leadership comes from the customary leadership that carries out customary rules that do not conflict with government regulations in the management of natural resources and the sustainable environment.","PeriodicalId":13849,"journal":{"name":"International Journal of Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85340271","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}

Several methods are available that can be used to detect FHR such as using the fetal electrocardiogram (FECG) that generated by fetus’ heart. Extracting FECG signals is considered a major challenge while the fetus is inside the mother uterus. Normalized Least Mean Square (NLMS) algorithm is one of adaptive filters that is chosen as adaptive filter to get FECG. Pan Tompkins algorithm is used for tracking R-peaks of heartbeat pulses of FECG signal. After detecting the RR interval a formula is used to calculate the bpm (heartbeat per minute) of FECG. Abdominal and direct FECG (ADFECG) database will be used to evaluate the implemented techniques as it has reference signal. At the end of research, calculated FHR is varied from 125.4 bpm to 130.3 bpm. When comparison is done between abdominal ECG (AECG) and direct FECG (DFECG), the error of FHR is 0.1%. The accuracy of R-peaks extraction is 100% where all R-peaks are detected by implemented techniques. MATLAB is used for signal simulations. This system will have ability to interpret the non-invasive FECG (NIFECG) database and compute its FHR.

Only truncated 5S rRNA gene but with its full spacer region was recovered from Carica papaya. Interestingly, intergenic spacer sequence cloned from Carica papaya contained two specific domains, a 30bp “CT” rich domain exhibiting 95-100% homology to several human chromosomes and a domain matching with mitrocomin precursor, a photoprotein from Mitrocoma cellularia.
