Porosity in Cement Paste01:18

Porosity in Cement Paste

553
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
The balance of water to cement in the mix is...

Porosity and Absorption of Aggregate01:20

Porosity and Absorption of Aggregate

950
Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the...

Fertilization01:38

Fertilization

93.9K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Spongy Bone01:09

Spongy Bone

11.8K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Oogenesis02:07

Oogenesis

71.3K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

The Bone Matrix01:18

The Bone Matrix

8.7K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

    Area of Science:

    • Reproductive biology
    • Genetics
    • Cell biology

    Background:

    • Oocyte development is essential for embryo formation but influenced by incompletely understood factors.
    • The nucleoporin-107 (NUP107) gene is vital for nuclear pore complex function in somatic cells.

    Purpose of the Study:

    • To investigate the role of NUP107 in ovarian development and female fertility.
    • To identify genetic factors contributing to abnormal ovarian development.

    Main Methods:

    • Identified a novel recessive missense mutation in the NUP107 gene in humans.
    • Replicated the mutation in the Drosophila NUP107 ortholog to study its effects.

    Main Results:

    • The NUP107 mutation led to abnormal ovarian development in humans and poor follicular development in Drosophila.
    • NUP107 demonstrated an evolutionarily conserved and ovary-specific function.
    • The mutation disrupted NUP107 function specifically in the ovary, not in somatic cells.

    Conclusions:

    • Missense mutations in NUP107 can specifically impair ovarian function.
    • This study suggests that other gene mutations may selectively affect gonadal function while sparing extragonadal tissues.
