Abstract: The Earth Geopotential Model of 2008 (EGM2008) is the product of the effort by the National Imagery and Mapping Agency (NIMA), USA at generating an accurate global geoid height model which will facilitate accurate conversion of geocentric ellipsoidal heights to their corresponding orthometric equivalent. This research assesses the Geoidal undulations determined from GPS/Leveling method and EGM2008 at 19 stations established on the ground surface. The assessment was done by comparing Geoidal undulations determined from GPS/Leveling and EGM2008 and using t-test statistical operation to find out whether there is a significant difference between the two methods........

Abstract: Background: The presence of heavy metals like copper, cadmium and lead in water bodies due to the discharge of effluents is of great concern because of its toxic nature. Hence, there is great need to eliminate them to safe level before discharge. Sawdust, as an agricultural waste which is highly efficient, readily available and relatively inexpensive, has the potential to be an applicable alternative adsorbent for heavy metals. Materials and Methods: Sawdust from a local furniture factory was procured. It was washed several times with distilled water to remove surface impurities and oven dried at a temperature of 75°C for 8 hours. The sawdust was then grinded to fairly fine particles and sieved to........

Abstract: Subjectivity is gendered. From the moment of its birth the human infant comes under a regime of gender under which one cannot be a subject without being male or female. Gender, Judith Butler asserts, is performative. It is created by acts which are really socially established ways of being a man or a woman. The "reiterative and citational practice" of gender norms constrains the gendered subject. A woman is "interpellated" as woman so that she internalizes the feminine norms like submissiveness, domesticity and passivity. Similarly, it is normative for a man to be dominant, aggressive and cruel on his women to ensure submission to his will. He has to "disavow" any marks of effeminacy or weakness within him. The gendered subject is constrained to repeat the norm because any deviant behaviour faces social abjection........

Abstract: Background: In Benin, palm oil fruits (Elaeis guineensis) are commonly used for the production of red palm oil and flavored palm oil (zomi). This study aimed at assessing the influence of fruit varieties and manufacturing processes on the zomi oil quality. Materials and Methods: Zomi oil was produced from Dura, Tenera and blend (50% Dura + 50% Tenera) varieties three different processes, identified during a previous work. A total of 45 zomi samples (15 from each sample) were studied. On the sample oil obtained, the determination of the color and the sensory attributes was done. The results showed that except fiber weight, the interaction of palm fruit variety and manufacturing processes was significant (P <0.05) for all other production parameters........

Abstract: Background: As the increasing of Greenhouse Gas (GHG) emissions is becoming an issue, one of the efforts made by the Indonesian government to overcome it is to issue a regulation for companies to do the Corporate Social Responsibility (CSR). Many references are used in disclosing environmental and social performance. One of the required disclosure references is to support the Sustainable Development Goals (SDGs). Materials and Methods: This study uses a quantitative approach with content analysis research methods. The population in this study are the 3 largest GHG emitting companies in the cement, ceramics, and food and beverage industries in Indonesia which are listed on the Indonesia Stock Exchange (IDX) from 2017 to 2020 with a total of 49 companies........
