![]() Vertical farming - the practice of growing food in stacked trays - isn’t new innovators have been growing crops indoors since Roman times. Done right, three technologies - vertical, cellular and precision agriculture - can remake the relationship to land and food. To address these challenges, new technologies promise a greener approach to food production and focus on more plant-based, year-round, local and intensive production. And pushing farmland into the wilds connects humans with reservoirs of viruses that - when they enter the human population - prove devastating. Similarly, “just enough, just in time” food supply chains are efficient but offer little redundancy. Agricultural scientists have known for decades that farm labour can be exploitative and hard, so it should surprise no one that farm owners had trouble importing labour to keep farms running as they struggled to ensure food workers stay free from the virus. If humanity is to have a hope of addressing climate change, we must reimagine farming.ĬOVID-19 has also exposed weaknesses with current food systems. Every day, more primary forest falls against a tide of crops and pasture and each year an area as large as the United Kingdom is lost. The number of domestic animals far outweighs remaining wild populations. ![]() Roughly 40 per cent of the Earth’s suitable land surface is used for cropland and grazing. Agriculture’s impact on the planet is massive and relentless.

These elementary particles are excitations of the quantum fields that also govern their interactions. Some particles, such as the photon, are their own antiparticle. These antiparticles can theoretically form a corresponding form of matter called antimatter. The electron has a negative electric charge, the positron has a positive charge. For example, the antiparticle of the electron is the positron. Particles have corresponding antiparticles with the same mass but with opposite electric charges. Mesons are also produced in cyclotrons or other particle accelerators. They occur after collisions between particles made of quarks, such as fast-moving protons and neutrons in cosmic rays. Mesons are unstable and the longest-lived last for only a few hundredths of a microsecond. Two baryons, the proton and the neutron, make up most of the mass of ordinary matter. Hadrons that contain an odd number of quarks are called baryons and those that contain an even number are called mesons. Quarks cannot exist on their own but form hadrons. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. There are three generations of fermions, although ordinary matter is made only from the first fermion generation. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. ![]() One of these men is Al Harrison (Kevin Costner), the gum-chomping head of the Space Task Group, whose single-minded quest to get the numbers right leads naturally to an egalitarian leadership style. So begins a rinse-repeat pattern of slow-clap moments where the women are disrespected or underestimated at work, only to show up a parade of crew-cut dolts in dress shirts and thin black ties. When they flash their credentials to a white cop who pulls them over, they're greeted with the first in a series of double takes. In the early '60s, she and her colleagues Dorothy Vaughan (Octavia Spencer), a mathematician who would later take over early IBM processing computers, and Mary Jackson (Janelle Monáe), a trailblazer in engineering, are shown carpooling to NASA together in broken-down Chevy Impala. Henson plays Johnson as a quietly insistent woman who made herself so indispensable that her presence in otherwise all-white offices and high-level meetings could not be denied. Now 98, Johnson has lived long enough to receive the Presidential Medal of Freedom from President Obama and have a computational facility named after her at Langley. Vincent) makes a running joke out of Johnson having to dash a quarter-mile across campus in high heels just to use the "colored bathroom." It takes her boss a while to put an end to this unsustainable folly, and her colleagues' respect comes even slower still. When Katherine Johnson, an expert in analytic geometry, gets promoted to a position in the Space Task Group, co-writer/director Theodore Melfi ( St. This wasn't a moral calculation so much as a practical one: America was losing the space race to the Russians, and NASA needed the best possible people to catch up, regardless of the color of their skin. In broad but mostly satisfying terms, Hidden Figures celebrates the few African-American women who broke out of the West Area Computers building because their talent was no longer worth suppressing. And it is about these human "colored computers" literally being hidden from view, tucked away in a segregated building on NASA's campus, a florescent-lit purgatory from which there was no path to deliverance. It is about the African-American women who carried out these vital functions in Langley, VA, without the public acknowledgement granted astronauts like Alan Shepard or John Glenn, or even the buzzcut white men at Mission Control. It is about the mathematics that served as a rationale and a backstop for manned space capsules launched into space and brought back safely to earth. Henson) and Dorothy Vaughan (Octavia Spencer) in Hidden Figures.īased on Margot Lee Shetterly's book, Hidden Figures has a triple-meaning title. Mary Jackson (Janelle Monae, left), Katherine Johnson (Taraji P. In their following work 54 they identified different types of capsule dynamics such as tank-treading, swinging, and tumbling. 20,50–58 Using two-dimensional numerical simulations, Shin and Sung 51 showed that the final equilibrium position for a given value of capsule elasticity varies with the Reynolds number. 46–49 Only recently, inertial microfluidics of deformable cells has caught attention. ![]() The dynamics of soft capsules is widely studied at low Reynolds numbers in canonical flows 41–45 and cellular blood flow simulations. 40įor biomedical applications of inertial microfluidics it is crucial to strive for a deeper understanding of the inertial migration of deformable capsules. Soft capsules experience an additional lift force induced by the deformability of the cell, which drives them towards the channel center and which thereby competes with the inertial lift force. Subsequently, Hur and co-workers 39 experimentally showed inertia-driven separation and enrichment of deformable capsules. 38 demonstrated ordering and separation of particles in a microchannel using inertial focussing, which gave rise to the field of inertial microfluidics. For almost five decades from the observation of the Segré–Silberberg effect, inertial migration was mainly a blue-skies-research problem. 36 Applying an external force to the solid particle along the channel axis, the resulting Saffman force 37 also contributes significantly to the force balance in the cross-stream direction. Inertial migration of a neutrally buoyant solid particle is essentially the result of a balance between shear-gradient lift force, directed towards the channel wall, 35 and a wall repulsion force, directed towards the channel center. Inertial focussing was first reported by Segré and Silberberg for solid particles with the well-known tubular pinch effect 21,22 and then spurred numerous theoretical, 23–26 computational, 19,27–30 and experimental 31–34 studies to gain a deeper understanding of this phenomenon. In this article, we investigate how different factors such as shape, softness, and position influence the motion of a pair of particles in a microfluidic channel. The possibility to attain high throughput makes inertial microfluidics an attractive option among other microfluidic particle-separation techniques. In contrast to common microfluidic lab-on-a-chip devices in which fluid inertia is negligible, inertial microfluidics operates in an intermediate range between Stokes and turbulent regimes, where flow is still laminar. 13 On the other hand, deterministic lateral displacements at low Reynolds number using appropriately placed pillars 14 and inertial microfluidics 15–20 exploit internal hydrodynamic forces to achieve particle separation. 9 Lab-on-a-chip techniques using external force fields include optical tweezers, 10 dielectrophoresis, 11 magnetophoresis, 12 and acoustophoresis. 8 Lab-on-a-chip devices for separating particles and biological cells rely on external force fields or internal hydrodynamic forces. In recent years, microfluidic 6 lab-on-a-chip devices 7 have emerged as a promising technique to precisely manipulate and control biological cells needed on a commercial level. 1 Introduction Biomedical studies of biological cells play a crucial role in diagnosing several fatal diseases 1 such as malaria, 2 cancer, 3,4 and the human immunodeficiency virus (HIV) infection, 5 to name a few. Furthermore, a pair with both capsules in the same channel half is more prone to become unstable than a pair with capsules in opposite channel halves. We show that stable pairs become unstable when increasing the particle stiffness. The observed two-particle motions in the present work can be categorized into four types: stable pair, stable pair with damped oscillations, stable pair with bounded oscillations, and unstable pair. We also change their deformability from relatively soft to rigid and choose spherical and biconcave particle shapes. We study the influence of different starting positions for mono- and bi-dispersed pairs. We perform three-dimensional lattice Boltzmann simulations combined with the immersed boundary method to unravel the dynamics of various mono- and bi-dispersed pairs in inertial microfluidics. ![]() This will help to develop an understanding of the dynamics of particle trains in inertial microfluidics, which are typical structures in multi-particle systems. ![]() The article focuses on the hydrodynamic interaction of two particles. Inertial microfluidics exploits internal hydrodynamic forces and the mechanical structure of particles to achieve separation and focusing. Lab-on-a-chip devices based on inertial microfluidics have emerged as a promising technique to manipulate particles in a precise way. ![]() Comes in a TSTAK Box with 2 x 2Ah Batteries and a Charger.

However, there are also limitations associated with this method, “The main limitation of AFLP in yeast systematics may be its inability to establish genetic similarities between species” (Lopes et al).ĪFLP is very powerful molecular technique with a wide variety of applications in species identification, strain differentiation, and detection of genetic similarities between organisms within the same species. After performing a cluster analysis with the AFLP data obtained through this study, the genetic relatedness of Saccharomyces cerevisiae and Dekkera bruxellensis was determined. In addition, AFLP can be useful for studying genetic variation in different yeast species used in wine making, “Amplified fragment length polymorphism (AFLP) was used to investigate genetic variation in commercial strains, type strains and winery isolates from a number of yeast species” (Lopes et al). AFLP can also be applied to criminal investigations and paternity testing. ![]() Besides detecting fragment polymorphisms, “The AFLP technique may be used for fingerprinting of cloned DNA segments like cosmids, P1 clones, bacterial artificial chromosomes or yeast artificial chromosomes (Vos et al). “For a wide range of taxa, including plants, fungi, animals and bacteria, AFLP markers have been used to uncover cryptic genetic variation of strains, or closely related species, that had been impossible to resolve with morphological or other molecular systematic characters” (Mueller et al). Further more, AFLP markers are very useful for studying genetic variation between closely related species. One of the key features of AFLP analysis is the detection of polymorphisms of genomic DNA fragments obtained through restriction digestion. And the third step is the analysis of the amplified fragments after visualization on a denaturing polyacrylamide gel.ĪFLP is a powerful molecular tool allowing simultaneous screening of a large number of DNA regions that are spread randomly throughout the genome. ![]() The second step consists of the amplification of certain restriction fragments with PCR primers (the primers are designed to target the adapters fused to the end of the fragments). There are several reasons for the use of two types restriction enzymes: generation of short DNA segments with good amplification and separation on the gel, the rare cutter will complement the frequent cutter by decreasing the number of generated fragments, and only one strand of the double stranded PCR products can be labeled. The first step involves restriction digestion of DNA with two types of enzymes (a rare and a frequent cutter), followed by the ligation of double-stranded oligonucleotide adapters, specific to the ends of the generated fragments. This PCR based tool utilizes restriction enzymes to digest genomic DNA to smaller fragments and consists of three main steps. AFLP is a DNA fingerprinting technique that can be used to answer a variety of research questions. ![]() It helped her recover photos when iPhone water damaged.
