The document discusses finding the volume of a sphere through an experiment using containers of different shapes. It involves filling a hemispherical container with flour and pouring it into a cylindrical container to determine the volume ratio. It then provides the formula to calculate the volume of a sphere as 4/3 * * r^3. Several example problems are worked out using this formula to find the volume or radius of various spheres.

Beyond Point Masses. IV. Trans-Neptunian Object Altjira Is Likely a Hierarchi...S辿rgio Sacani
油
Dynamically studying trans-Neptunian object (TNO) binaries allows us to measure masses and orbits. Most of the known objects appear to have only two components, except (47171) Lempo, which is the single known hierarchical triple system with three similar-mass components. Though hundreds of TNOs have been imaged with high-resolution telescopes, no other hierarchical triples (or trinaries) have been found among solar system small bodies, even though they are predicted in planetesimal formation models such as gravitational collapse after the streaming instability. By going beyond the point-mass assumption and modeling TNO orbits as non-Keplerian, we open a new window into the shapes and spins of the components, including the possible presence of unresolved inner binaries. Here we present evidence for a new hierarchical triple, (148780) Altjira (2001 UQ18), based on non-Keplerian dynamical modeling of the two observed components. We incorporate two recent Hubble Space Telescope observations, leading to a 17 yr observational baseline. We present a new open-source Bayesian pointspread function fitting code called nPSF that provides precise relative astrometry and uncertainties for single images. Our non-Keplerian analysis measures a statistically significant (2.5) nonspherical shape for Altjira. The measured J2 is best explained as an unresolved inner binary, and an example hierarchical triple model gives the best fit to the observed astrometry. Using an updated non-Keplerian ephemeris (which is significantly different from the Keplerian predictions), we show that the predicted mutual event season for Altjira has already begun, with several excellent opportunities for observations through 2030.Grade 08-SCIENCE (BIOLOGY)CELL DIVISION.pptx

Cell division is a fundamental biological process that enables the growth, development, and repair of living organisms. It's the process by which a parent cell divides into two or more daughter cells, each carrying a complete set of genetic instructions. This intricate process occurs in two primary ways: mitosis and meiosis. Mitosis is responsible for the creation of identical daughter cells, ensuring the maintenance of genetic information for growth and tissue repair. Meiosis, on the other hand, is a specialized form of cell division that occurs in sexually reproducing organisms, producing gametes (sperm and egg cells) with half the number of chromosomes, contributing to genetic diversity in offspring.Variation and Natural Selection | IGCSE Biology

SILICON IS AN INHIBITOR OF CERTAIN ENZYMES IN VITROLilya BOUCELHA
油
Silicon is considered an inorganic biostimulant and a prophylactic extracellular agent that allows the stimulation of a
wide range of natural defences against abiotic and biotic stresses. However, little or no work has focused on the direct action of silicon on some enzymes. Indeed, during this study, the action of silicon was studied in vitro by direct contact of this element at different doses with the enzymatic extracts of Trigonella foenum-graecum L. (fenugreek) seeds. Our results showed that silicon
strongly inhibited antioxidant and hydrolytic enzymatic activities. The percentage of this inhibition depends on the dose of silicon and the type of enzyme. The most sensitive enzymes to this inhibition were SOD and lipases whose activity was totally inhibited at
4 mM and 7 mM respectively. However, we report that the inhibitory action of silicon was limited to 50% for GPOX whatever the concentration of silicon used, the plateau being reached at 10 mM for GPOX and at 70 mM for proteases. Since these enzymes are mainly metallo-dependent, we hypothesize that their inhibition by silicon may be due to interactions between silicon and the metals involved in the functioning of each enzyme. Our study shows that silicon can be used as an inhibitor of enzymes involved in certain diseases.

SUMMARY
Based on human relationship with bacteria, virulence is one of the most important case to us. Some forms of virulence thought to arise only from the actions of bacteria are not actually caused by them but are indirectly influenced by another counterpart in the microbial mix of the ecosystem called bacteriophage; viruses that only infect prokaryotes such as bacteria but not eukaryotes. Bacteriophages preferably attack bacteria due to the lack of specific receptors for phages on eukaryotic cells which are found in bacteria e.g. peptide sequences and polysaccharide moieties in gram positive and gram negative bacteria, bacterial capsules, slime layers, flagella etc. They recognize and bind to bacteria using appropriate receptors, subsequently proceeding to inject their genome called prophage into their host. This review focuses on the most probable outcomes of phage-host interactions via the lytic and lysogenic cycles which are therapeutic effect and pathogenicity/resistance to antibiotics respectively. By lysogenic conversion or transfer of acquired genetic materials via transduction, phages can confer unusual traits such as virulence and antibiotics resistance. Important pathogenic bacteria that cause persistent and critical infections which have their pathogenicity engineered by phages include Pseudomonas aeruginosa, Salmonella enterica, Escherichia coli, Vibrio cholerae, Staphylococcus spp., and Clostridium spp.
The prophages influence their virulence in a variety of ways which include: contribution to the production of phage-encoded toxins, modification of the bacterial envelope, mediation of bacterial infectivity, and control of bacterial cell regulation. The unwavering threat of antimicrobial resistance in global health, extreme difficulty involved in developing novel antibiotics, and the rate at which microorganisms develop resistance to newly introduced antimicrobials have sparked urgency and interest in research for effective methods to eradicate pathogenic bacteria and limit antibiotic resistance. As a result, interest in phage therapy has been reignited because of the high efficiency in detecting and killing pathogenic bacteria by phages.

Rytis Jurkonis from Kaunas University of Technology (Lithuania) presented their recent work entitled Automating Compression Ultrasonography of Human Thigh Tissue and Vessels via Strain Estimation." Rytis presented on the methodology along the novel wearable hardware developed to automate compression ultrasonography for DVT detection in the lower limbs. In addition, preliminary results were shared, highlighting the feasibility of an operator-independent method to perform compression ultrasonography.
Presented at BIOSTEC 2025 in Porto, Portugal.
About ThrombUS+: Our interdisciplinary approach centers around creating a novel wearable diagnostic device utilizing autonomous, AI-driven DVT detection. This groundbreaking device incorporates wearable ultrasound hardware, impedance plethysmography, and light reflection rheography for early clot detection. ThrombUS+ is designed for postoperative patients, those undergoing lengthy surgical procedures, cancer patients, bedridden individuals at home or in care units, and women during pregnancy and postpartum.Melaku Tafese Awyulachew's_Official letters between organizations and researc...

- 3. Finding the formula for the volume of sphere 1. Prepare four containers. One is hemisphrerical and the other is cylinder with their radii r and cylinder height is 2r. 2. Fill up the hemisphrerical with some flour until it is full, and then pour out the flour into the cylinder container. How many times do you have to fill up the hemisphrerical until the cylinder container gets full? 3. Based on the activity, can you determine the volume of sphere?
- 5. 1. V = 4/3 3,14 103 = 4.186,67 2.Volume gambar 2
- 6. 3. Wakingup space on the image (III) is a ball that is cut in half 40/360 parts. So that its volume can be determined as follows.
- 7. Question 4. A hot air balloon if filled with helium. Find the volume of gas needed to fill a balloon with a diameter of 30 m. ANSWER
- 8. Solution : D = 30 m, r = 15 m V = 4/3* *r続 = 4/3 * 3,14 * 15続 = 4/3 * 3,14 * 3375 = 4/3 * 10597,5 = 14130 m続
- 9. 6. The Volume of a sphere is 1,437 cm続 . Find the radius of the sphere with 22/7. ANSWER
- 10. V = 4/3 * * r続 1,437 = 4/3 * 22/7 * r続 r続 = 1,437 : 88/21 r続 = 4.312/3 * 21/88 r続 = 4,312 * 7/88 r続 = 49 * 7 r続 = 343 r = 7 Thus, the radius of sphere is 7 cm
