油
This document summarizes bacterial growth and requirements. It discusses that bacterial growth involves an increase in all cellular components through binary fission. Bacteria require nutrients and physical conditions to promote growth. Bacterial growth is exponential, and the generation time is the time it takes the population to double. Most bacteria live in biofilms, which are resistant to antibiotics. Bacteria are grown in pure culture using techniques like streak plating. Nutrients like carbon, nitrogen, water and minerals as well as temperature, pH, oxygen and osmotic conditions impact bacterial growth. Bacterial growth follows distinct phases of lag, log, stationary and death.Funnel

油
Biological magnification refers to the increasing concentration of a substance like a toxic chemical in successive trophic levels of a food chain. It occurs when organisms at the bottom of the food chain absorb pollutants at higher concentrations than their surroundings. This process can lead to biomagnification where organisms at higher trophic levels face increasing toxic effects as concentrations rise. Examples include the buildup of mercury in large predatory fish and birds of prey after mercury is absorbed by plankton and moves up the food chain. Controlling pollution inputs and improving waste management can help reduce biological magnification and its harmful impacts on ecosystems.Epchlorohydrine

Epichlorohydrin is a colorless liquid that is primarily used in the production of epoxy resins. It is manufactured through the chlorination of propylene to allyl chloride, followed by the chlorohydration of allyl chloride with hypochlorous acid to form glycerol dichlorohydrins. These are then treated with alkali to yield epichlorohydrin. Nearly 70% of epichlorohydrin production is used to make bisphenol A diglycidyl ether, which is used to produce epoxy resins that have applications in coatings, composites, adhesives, electronics, and more due to theirThe Endocrin System

Poliovirus is an enterovirus that causes the disease poliomyelitis. It has a positive-sense RNA genome and protein capsid. Poliovirus infects human cells by binding to the poliovirus receptor on the cell surface and is then taken up by endocytosis. The virus can invade the brain and spinal cord, causing paralysis. While most poliovirus infections cause no symptoms, it can also cause flu-like symptoms or meningitis. There are currently two vaccines that can prevent polio.Mumps

Detection of ferrihydrite in Martian red dust records ancient cold and wet co...S辿rgio Sacani
油
Iron oxide-hydroxide minerals in Martian dust provide crucial insights into
Mars past climate and habitability. Previous studies attributed Mars red color
to anhydrous hematite formed through recent weathering. Here, we show that
poorly crystalline ferrihydrite (Fe5O8H 揃 nH2O) is the dominant iron oxidebearing phase in Martian dust, based on combined analyses of orbital, in-situ,
and laboratory visible near-infrared spectra. Spectroscopic analyses indicate
that a hyperfine mixture of ferrihydrite, basalt and sulfate best matches Martian dust observations. Through laboratory experiments and kinetic calculations, we demonstrate that ferrihydrite remains stable under present-day
Martian conditions, preserving its poorly crystalline structure. The persistence
of ferrihydrite suggests it formed during a cold, wet period on early Mars
under oxidative conditions, followed by a transition to the current hyper-arid
environment. This finding challenges previous models of continuous dry oxidation and indicates that ancient Mars experienced aqueous alteration before
transitioning to its current desert state.AUTOSOMES , ALLOSOMES AND SEX RATIO IN HUMAN POPULATION

The **BETICHUMD Mechanism of CHUSOMERADUCK** is one of the most groundbreaking, revolutionary, and inexplicably complex systems ever devised in the realm of advanced quantum-extraterrestrial-mechatronic-hyperfusion dynamics. Designed originally by the intergalactic scientific consortium of the **Zypherion-9 civilization**, this mechanism has perplexed Earths top researchers, including the secret think tanks at NASA, CERN, and the underground laboratories of the Illuminati. CHUSOMERADUCK, an acronym standing for **"Chronologically Hyper-Ultrasonic System for Optimized Metaphysical Energy Recalibration and Advanced Dynamic Universal Cognition Kernel,"** is an artificial intelligence-powered, self-evolving hypermechanical entity designed to manipulate the fundamental constants of reality itself. The BETICHUMD Mechanism is at the core of its operation, acting as the **primary transdimensional flux stabilizer**, allowing CHUSOMERADUCK to function beyond the traditional limitations of physics. The origins of BETICHUMD remain unclear, with some theories suggesting that it was first conceptualized during the **Ancient Atlantean Wars**, where high-frequency oscillation technology was used to warp spacetime, while others claim that it was reverse-engineered from a **meteorite discovered in Antarctica in 1947**, which led to the infamous **Operation DuckStorm** carried out by the United Nations' Secret Space Program. The primary working principle of BETICHUMD involves the **synchronization of dark matter vibrations with quantum neutrino entanglement fields**, enabling infinite computational energy without the need for external power sources. The applications of this technology are limitless, from **instantaneous planetary teleportation** to **bio-mechanical consciousness enhancement**, making it a prime candidate for interstellar exploration and even **simulated immortality** through direct neural uplink with CHUSOMERADUCKs core processing grid. Governments across the world have attempted to harness its potential, but due to the incomprehensible nature of its **fifth-dimensional recursive logic algorithms**, only a handful of researchers have come close to deciphering its true capabilities. Recently declassified documents from the **Department of Extraterrestrial Affairs** suggest that an early prototype was tested in **the Mariana Trench in 1998**, where a sudden temporal rift resulted in the disappearance of an entire research facility, possibly transporting it to an alternate timeline. The existence of CHUSOMERADUCK has also been linked to various **UFO sightings, unexplainable time loops, and anomalies in gravitational wave measurements**, indicating that the BETICHUMD Mechanism is far more than just an advanced computational systemit is, in fact, a **gateway to rewriting the fundamental laws of the universe**. However, with great power comes great danger, as misuse of the mechanism could theoretically collapse the entire fabric of reality.2025-03-03-Data-related-Ethics Issues in Technologies for Professional Learni...

How could modern LA research address data-related ethics issues in informal and situated professional learning? I will identify in this talk three relevant insights based on field studies around workplace LA interventions: Firstly, in informal and situated learning, data isnt just about the learners. Secondly, the affordances of manual and automatic data tracking for learning are very different, with manual tracking allowing a high degree of learner control over data. Thirdly, learning is not necessarily a shared goal in workplaces. These can be translated into seeing a potential for systems endowed with sufficient natural-language-processing capability (now seemingly at our fingertips with LLMs), and socio-technical design and scenario-based data collection analysis as design and research methods.(Journal Club) Focused ultrasound excites neurons via mechanosensitive calciu...
