  1. 1. Från observation till teori. En intervjustudie om biologins karaktär och arbetsmetoder.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Amanda Bladh; [2023-06-12]
    Nyckelord :Biologins karaktär; biologins arbetsmetoder; biologiämnets centrala innehåll; gymnasielärares resonemang; undervisning i biologiämnet.;

    Sammanfattning : The nature of biology and the nature of practical methods in biology are a part of the core content of the biology syllabus in the Swedish upper secondary school. The nature of biology describes the subject's epistemology such as the knowledge and how it is arranged in theories, laws and models. LÄS MER

  3. 2. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Fredrik Salomon-Sörensen; [2023]
    Nyckelord :Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Sammanfattning : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. LÄS MER

  4. 3. Varför bevara natur? : Biologers roll inom bevarandeetik av natur i en antropocentrisk värld

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Umi Wurnell; [2023]
    Nyckelord :Conservation; ethics; ecocentrism; anthropocentrism; biologists; Bevarande; etik; ekocentrism; antropocentrism; biologer;

    Sammanfattning : Även om bevarandebiologi finner sina rötter inom ekocentrismen, är bevarande idag oförnekligt centrerat runt människan och hennes behov. En del forskare menar dock att detta synsätt kan komma att underminera syftet med bevarande. LÄS MER

  5. 4. Redeveloping a mixing system in a biomedical device to improve system control and increase its intelligence and effectiveness : Redeveloping a mixing mechanism using ESP32, TMC5130, Bluetooth and CAN-bus

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Aref Bahtiti; [2023]
    Nyckelord :CAN-bus; Bluetooth classic; Stepper motor; TMC5130; ESP32; Open loop system; Smartphone application;

    Sammanfattning : Biogas is a renewable energy source produced by decomposing organic matter in the absence of oxygen. Without oxygen, organic matter is broken down in this process, producing a mixture of gases that may be used for a variety of tasks, such as heating, cooking, and producing power. LÄS MER

  7. 5. Sex-associated genomic variation in two ecotypes of Littorina saxatilis on the Swedish west coast

    Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

    Författare :Amin Ghane; [2022-09-26]
    Nyckelord :Littorina saxatilis; Sex chromosomes; Sex determination systems; Sex-associated genomic region;

    Sammanfattning : Sex, one of the most conspicuous characteristics of living organisms, has always been fascinating for biologists. The diversity of sex goes much beyond a simple distinction between males and females. Many organisms have more than two mating entities, and many species show some degree of hermaphroditism, at least in part of their life cycle. LÄS MER
