In this field of science, animals are equipped with electronics to measure a wide range of parameters. In the case of cattle, the electronics are attached to collars and mounted around the animal's neck. On the one hand, this is dangerous, as cattle can severely injure or even kill a person with their head, and on the other hand, the collars have to be configured and readjusted. The animal has to be continuously restrained and is therefore exposed to stress.\r\nThis procedure has the disadvantage that it requires an animal testing permit under the German Animal Welfare Act. Getting such approval is time-consuming and, depending on the purpose, not ethically justifiable. In addition, a sketch of the planned system, including attachment to the animal, is required for approval of the experiment.\r\nThe idea is to build a simple animal model that has the appropriate neck circumference and shape, is sufficient for initial electronic tests, and is also easy to assemble. The attached image shows a construction proposal that consists of a few parts and is financially affordable (100€).\r\n","created_at":"2021-07-04T16:07:53.876Z","updated_at":"2021-09-13T06:00:54.854Z","zenodo_id":5502173,"doi":"https://doi.org/10.5281/zenodo.5502173","subject":null,"tags":["cow","experiment","german animal welfare act","electronics"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":true,"attachment_file_name":"microcow_img.PNG","attachment_content_type":"image/png","attachment_file_size":2058512,"attachment_updated_at":"2021-07-04T16:07:53.845Z"},{"id":858,"title":"agricolaeplotr: An R package for visualising experimental designs in science and engineering","sha":"7d5007cfc09d9b9f7958eb6d8ffb5dac","user_id":null,"state":"published","body":"Experimental designs are widely used in the life sciences to substantiate hypotheses through experiments. In the life sciences, this is an indispensable part of gaining scientific knowledge. In addition, open source software is increasingly used in science and engineering. One important programme is R, which is used as a statistical programme for evaluating experiments. The most important R package for designing experiments is the agricolae package, which creates many common experimental designs. However, apart from simple matrix sketches for selected designs, the package does not contain any visualisations of the experimental designs. This gap will be closed by the planned agricolaeplotr package. \r\n\r\nThe planned workflow: The user can enter an object as input, which contains an experimental design from the agricolae package and gets a field map output with a few parameters. \r\nThis shows the spatial dimensions of the experiment, as well as the location of the individual plots in the experiment. In addition, the plot numbers are output as labels, and the plots are coloured according to the levels of a factor (see attachment). This can be further processed, as pure ggplot2 functions are used. These maps can be used to communicate with project stakeholders in science and education.\r\n","created_at":"2021-07-04T16:39:26.157Z","updated_at":"2021-09-13T06:00:54.858Z","zenodo_id":5502175,"doi":"https://doi.org/10.5281/zenodo.5502175","subject":null,"tags":["r","package","agriculture","visualisation","science","engineering"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":false,"attachment_file_name":"fieldmap_three_factors.pdf","attachment_content_type":"application/pdf","attachment_file_size":15333,"attachment_updated_at":"2021-07-04T16:39:26.137Z"},{"id":883,"title":"Agrimath - Mathematical Proof of Methods Used in Agricultural Sciences","sha":"42c4bf3373de5ab37f626cffff520163","user_id":null,"state":"published","body":"Scientific publications in peer-reviewed journals represent the backbone of science, because information in this medium ideally passes through a review process and is released for publication after peer review. This increases credibility, as a selection process usually identifies and sorts out faulty work. However, even in retrospect, after the paper has been published, errors can occur that remained unknown or unmentioned in the scientific community.\r\n\r\nThe idea of the project is to mathematically evaluate methods in agricultural science based on classical forms of mathematical proof. Emphasis will be placed on grassland science as the main subject of methodology. The methods used will be mathematically proven and, if necessary, revised after contradiction. Correct techniques should also be named so that further work can be done with them. \r\n\r\nThe goal is a consistent mathematical evaluation of the toolbox of agricultural scientists to give the work additional credibility. The explicit non-goal is to merely showcase authors of papers that use methodologies that are mathematically proven to be inappropriate or biased. Or offending agricultural science projects and their stakeholders.\r\nThe findings will be read primarily by agronomists in an effort to improve methodology.","created_at":"2021-09-26T04:27:34.222Z","updated_at":"2021-10-28T06:04:26.481Z","zenodo_id":5606093,"doi":"https://doi.org/10.5281/zenodo.5606093","subject":null,"tags":["agriculture","grassland sciences","mathematics","proof","paper"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":true,"attachment_file_name":null,"attachment_content_type":null,"attachment_file_size":null,"attachment_updated_at":null},{"id":884,"title":"Publication of conference lightning talks in scientific journals shown on a exemplary lightning talk about nomograms ","sha":"19d667ad863e5dc1fe20d0b4a6c38af6","user_id":null,"state":"published","body":"Lightning Talks have become a popular format at conferences. Within five minutes, a topic is presented that meets scientific standards. In this time, information can be presented that is also contained in papers. In many scientific fields, citations are made only from written papers (for ease of reference), even though oral and videotaped information are equivalent. Talks are rarely cited. However, citations represent the leading currency in science. This idea aims to fill this identified gap.\r\n\r\nThis Lightning Talk deals with nomograms. It shows how they are used and what advantages and disadvantages they have in contrast to computer-aided predictions. It will also show that this technique has been used for a long time and is still presented in leading journals. The slides of the talk are provided as a pdf file and are stored on zenodo.com using this approach.\r\n\r\nThe presentation is structured in classical order: (Introduction, Methodology, Results And Discussion) [IMRAD]. The transcript of the presentation is shown as a Jupyter Notebook, as this also allows computer code to be displayed and run through. References are recorded at the end. Here, this presentation represents an extension of knowledge from the audience, since the technique of nomograms is seldomly taught except engineering and medicine.\r\n ","created_at":"2021-09-27T17:38:22.349Z","updated_at":"2021-11-15T16:21:28.456Z","zenodo_id":5606096,"doi":"https://doi.org/10.5281/zenodo.5606096","subject":null,"tags":["lightning talk","python","nomogram","citations"],"vote_count":2,"view_count":1,"score":2.1,"deleted":false,"muted":false,"tweeted":true,"attachment_file_name":"Nomograms(1).pdf","attachment_content_type":"application/pdf","attachment_file_size":268192,"attachment_updated_at":"2021-09-27T17:38:22.329Z"},{"id":926,"title":"Pattern Mining in Grassland Science","sha":"e7c21212d54de1a106689ba17610735d","user_id":null,"state":"published","body":"This article presents ideas on how pattern mining can be applied in grassland science, where there is a high demand for rule pattern recognition, evaluation, and selection. In principle, vegetation data are well suited for pattern mining because they are available in a table structure that can be easily read by a program. Some of the application areas are listed below:\r\n\r\n1. Suggestion of suitable plants to increase biodiversity in a field. \r\n\r\n2. Identify and analyze patterns that favor the occurrence of harmful organisms in order to develop effective counterstrategies in pasture management. \r\n\r\n3. Optimization of cattle grazing of grasslands, as environmental factors can also be related to plant traits with pattern mining. Animal specific factory can be included if necessary.\r\n\r\n4. Optimization of organic fertilization on extensive areas (also sub-area specific) in order to harvest high yields for food purposes on the one hand, but not to endanger biodiversity on the other hand.\r\n\r\n5.

The development of animal-guided grazing requires geodata enriched with additional information to perform scientifically sound spatiotemporal evaluations. Existing animal trackers either cost 5000€ per device, as with the well-known GPS Collar PLUS, and are also protected by patents, so open research with easy expandability of sensors is not possible. In addition, most devices do not provide real-time information because there is no wireless transmission built in. My approach is therefore to build an open hardware solution using an LGT-92 device as the basis. Since the blueprints are openly available, the device can be easily reverse engineered. This will be placed in a housing that will be mounted on a collar. It can also be attached to existing collars to allow direct on farm research. The cost is around 60€ without VAT and without LoRaWAN router. The amount of data for up to 100 transmitters can be handled with a Raspberry Pi 3. For better camouflage, the housing can be created from the 3D printer, which allows camouflage pattern by matching colors.","created_at":"2022-03-20T16:33:37.780Z","updated_at":"2022-06-15T06:00:38.168Z","zenodo_id":6643849,"doi":"https://doi.org/10.5281/zenodo.6643849","subject":null,"tags":["cattle","open source hardware","tracking device","nature conservation","grazing"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":true,"attachment_file_name":"cowcam.pdf","attachment_content_type":"application/pdf","attachment_file_size":445973,"attachment_updated_at":"2022-04-14T19:43:47.609Z"},{"id":934,"title":"Application of design of experiment methods from the industrial environment to crop science and medicine","sha":"730907327d592ef663ea9154f130e6b1","user_id":null,"state":"published","body":"In all scientific and engineering disciplines, the design of experiment is used to create experimental plans. Particularly in industrial experimentation, methods are available that are hardly or not at all used in agriculture. For example, the surface response method in agricultural sciences is only used in mechanical engineering and the adjustment of agricultural machinery.\r\n\r\nThe work project therefore tries to combine ideas from both fields in order to improve experiments in crop science so that more accurate results can be obtained with fewer plots. \r\n\r\nFor example, methods such as fractional factorial designs and Plackett-Burman types are a possible extension when it comes to crop production systems. If there are already literature values for questions, optimal designs (D, I, A, G, T, E optimal) are also a possibility to achieve more precise results with fewer plots.\r\n\r\nThe challenge is to transfer the experimental designs from the industry into a plot form, as it is used in agricultural sciences and medicine. Especially the apsect of spatial influence has to be taken into account, as this phenomenon does not appear in this form in industrial trials, but is omnipresent in crop science due to natural inhomogeneous soil conditions.","created_at":"2022-04-24T18:37:07.016Z","updated_at":"2022-06-15T06:00:38.173Z","zenodo_id":6643867,"doi":"https://doi.org/10.5281/zenodo.6643867","subject":null,"tags":["design of experiment","life sciences","optimal designs","crops"],"vote_count":0,"view_count":1,"score":0.1,"deleted":false,"muted":false,"tweeted":false,"attachment_file_name":"html_doe_industry.pdf","attachment_content_type":"application/pdf","attachment_file_size":434219,"attachment_updated_at":"2022-04-26T14:01:06.114Z"}]
