Dissection of Laboratory Animal and Sample Collection for Histology
No full textThe starting point for the laboratory investigation of a dissection of laboratory animal for experiment is the taking of samples. This review considers some general principles involved in sample collection for histology (Liu et al., 2016). For disease diagnosis, the tissues sampled should be representative of the condition being investigated and the lesions observed. Samples should be taken with care, to avoid undue stress or injury to the animal or danger to the operator. Where appropriate, samples should be collected aseptically, and care should be taken to avoid crosscontamination between samples (Lapage, 1958).
Mice and rats are the most used animals in experimental researches, the anatomical, histological and genetic differences between species should be carefully evaluated, to better apply the study model and avoid unnecessary waste avoid (Corte et al., 2021). Currently, the implantation of defined genetically and sanitarily laboratory animals has aided in new discoveries, through experimental models, contributing to the prevention of uncured diseases such as cancers, AIDS, and multiple sclerosis, and also for the development of new surgical treatment techniques. Other applications correspond to the vaccines development, monoclonal antibodies, evaluation and control of biological products, pharmacology, toxicology, bacteriology, virology and parasitology, and basic immunology studies, immunopathology, organ transplants and immunosuppressive drugs development. However, with technological advances, it is now possible to obtain satisfactory results through alternative methods in vitro, using cell culture and other methods, allowing the 84 replacement of laboratory animals (Gunatilake, 2018)

The Need to Redefine Management from the View Point Of Scarcity: The Ontological and Epistemogical Consideration
No full textThe objective of this research paper was to study the expediency in considering the causative factor of the emergence of management, so as to pointedly appreciate its original meaning. This research paper presented the need to redefine management by management scholars, scientists, students and researchers; shifting from the popular process or applied definition of management, which dwells only on the application and administration of management, rather than the ontological and epistemological viewpoint of management, which ideally takes our focus back to the foundation of management. This study looked at management from its default state, basing its definition on the doctrines of logicality and rationality. The study is anchored on redirecting researchers’ minds to the root cause of management as against the emphasis on the application and administration of management by the huge body of literature. This research paper posed as contributing to the body of knowledge a new way to looking deeply at management as a construct of natural circumstances
Analysis of Barcode System Design and Checklist to Reduce the Lead Time of Delivery of Goods using FIFO Method at PT Indofood TBK Company of Indonesia
No full textIndofood, in carrying out goods storage and retrieval activities, is carried out without a barcode and checklist system. Without this system causes high lead times, referring to the time recorded by the SAT system. This system is used by management to control the loading/unloading movement of the company. Longer times often result in inefficiency and wasted resources, and companies should review their processing times against benchmarks to identify ways to improve their lead times.
The purpose of this study is to provide improvement efforts to overcome delivery errors on finished goods, reduce the lead time of the delivery process with the kanban system through the FIFO method, and compare the difference in the lead time of the delivery process before and after the procedure. The author's research process in carrying out research from planning to carrying out research at a specific time. The analysis carried out is to evaluate the results of the delivery system improvement, search for goods to be sent based on the delivery plan, and the amount of time required to make deliveries based on the lead time displayed via SAT. The results showed that the kanban checklist design using the FIFO method could reduce problems in shipping in and out of products in the warehouse by reducing recording errors and accelerating the recording process quickly, precisely and accurately. The product process flow based on the kanban checklist system makes it easier for operators in the implementation process from incoming products to outgoing products. Item data will be entered automatically into the existing computer kanban checklist using the FIFO method. The type of barcode used is a barcode that can input data in the form of letters, numbers and symbols. The company needs this type because the data inputted in the barcode uses these three forms
Study of Air Quality Detection using Machine Learning Techniques
No full textOver the past few decades, due to human activities, industrialization, and urbanization, air pollution has become a life-threatening factor in many countries around the world. Air, an important natural resource, has been compromised in terms of quality by economic activities. pollution is a severe problem in areas where population density is high such as metropolitan cities. Various sorts of emissions caused by people’s actions, like transportation, power, and fuel use, are affecting air quality. Considerable research has been dedicated to predicting instances of poor air quality, but most studies are limited by insufficient longitudinal data, making it difficult to account for seasonal and other factors. We forecast air quality by using machine learning to predict the air quality index of a given area. The air quality index is a dataset for a typical measure used to indicate the pollutant (SO2 NO2, RSPM, SPM, and more) levels over a period. The ML models like a Decision tree and Random Forest Classifier are implemented and compared to show better accuracy
Study on Human–elephant (Loxodonta africana, Blumenbach, 1797) conflict, prevention and mitigation in Babile Elephant Sanctuary, Eastern Ethiopia
No full textThe focus of this paper is to study the Human-Elephant Conflict (HEC), Prevention, Mitigation methods in Babile Elephant Sanctuary, Eastern Ethiopia. Purposive and random sampling methods were used for primary data collection. Accordingly, a total of 138 Households were selected from four Peasant Associations that were close to the sanctuary for interview. Moreover, Focus group discussion, site observations, and secondary data of the last five years (2016-2020) related to HEC. The result showed, 87.7% of respondents thought that crop-raiding by elephants and 85% of them viewed, death of 16 elephants by humans were the cause for conflict. Above 54.3% and 37.7% of them also thought as 22 human and 24 livestock died respectively. Besides, 27% of them indicated, 647.32 quintal of Zea mays (31.27 %) and Sorghum bicolor (46.22%) costing, 67,107.2 ETB-Ethiopian Birr (out of 87,657.27 ETB or 2,369.62 USD) were lost. However, all (100%) of them thought that there was no compensation given for the lost crops. Visual signals (setting fire and lighting torches) and shouting and hitting metal objects (acoustic methods) were used as a major mitigation measure. While beehives fences and digging trenches were identified as minor preventive measures. Based on the study results, the following inference is drawn: identifying and documenting the existence of HEC information to build the knowledge gaps on areas where these challenges prevails and implementing various measures of technical(biological and physical methods: farming of cash crops which is less attractive to elephants, fencing), socio-economic (building community owner ship and educational programs to school, benefit community by employee in development works),and financial strategy set up (compensation losses and revenue sharing) are crucial methods to reducing conflict and co-exiting human and elephant. 
Population size vs. Age structure and Seasonal movement pattern of African Elephants (Loxodonta africana, Blumenbach, 1797; Elephantidae) in Babile Elephant Sanctuary, Eastern Ethiopia
No full textThe focus of this paper is to study the population size and age structure of elephants, and their seasonal movement patterns in Babile Elephant Sanctuary (BES), Eastern Ethiopia. The study was carried out between May 2019 and April 2020. The population size of the elephant was estimated indirectly from the dung droppings using line-transect methods within a 42 km2 area; of which, each 12 km2 area in riverine and woodland, and 18 km2 in bushland habitats. The total estimate of the elephant population for the sanctuary was (230+20) or between (210 and 250). Besides, Elephant numbers were also estimated directly from sightings. The maximum number observed in a herd was 75. There was a declining trend for the past 49 years in the elephant population. The observed density for the whole sanctuary was 0.033 elephants per km2. In the elephant age structure, there were more intermediate (47%) and very few sub-adults (2.6%) size classes identified. The movement pattern of elephants was studied based on footprints, dung piles, and feeding signs The GPS recorded routes were marked on a geo-referenced map of the area using a GIS program (Arc map10.8). The result revealed that the present wet and dry seasonal movement patterns of elephants were noted following almost the Erer and Gobele valley routes in the oromia region of the sanctuary. Based on the study results, the following inference is drawn: identifying and documenting up-to-date information on population size and age structure, and seasonal movement of African elephants (i.e., the migratory routes and foraging areas for complete protection to maintain the animal's natural migratory patterns without disturbance) in BES is important to build gaps in knowledge for conservationists to design plans for restoring the species and sustaining the elephant’s existence. Therefore, strengthening the capacity of management and enforcing laws can minimize intimidation and enhance opportunities.
