Aroid is the common name for members of the Araceae family of plants, sometimes known as the Philodendron or Arum family. The sometimes beautiful and sometimes bizarre combination of spathe and spadix known as the inflorescence, and sometimes referred to as a flower, is a distinguishing feature of all aroids. The mission of the International Aroid Society is to provide information, assist in the distribution of unusual species and provide fellowship to everyone with an appreciation for this wonderful plant family.

The Scott Arboretum will be having its fifth Unusual Annuals and Tropicals Sale on May 15-16, 2015. For many years the Scott Arboretum has showcased interesting tropicals and annuals in containers and various gardens around the campus from May to November. Tropical plants such as Alocasia, Colocasia, Xanthosoma (elephant ears), Canna; Ensete, Musa, and bromeliads create an effect that reminds you of the tropics. These plants are often hard to find in garden centers, so the Arboretum has decided to offer you many of the more unusual selections we have tried over the years. We will offer limited quantities of more than 200 selections of unusual tropicals and annuals. Spring dividends will be available for members of the Scott Arboretum at the Sale.. ...

You need to distinguish between two things here. Virtual particles either arise because of vaccuum fluctuations, but they also originate as the force mediating particles between matter particles. In your example, the energy for the virtual particles does NOT come from the vaccuum but comes from the actual interaction between two matter particles. If you have two electrons that interact via the exchange of a virtual photons, then this photon arises as the fluctuation of a spin 1 field (this is a tricky issue however because of the zero photon mass). These fluctuations are caused by the two electrons. Think of the two electrons as if they were sitting on a mattress that will start to vibrate. These vibrations correspond to the virtual particle that goes from one electron to another. Both repulsive and attractive forces are treated this way in QFT. A force is represented by the exchange of this virtual particle that transports a definite momentum and therefore (because of HUP) the field ...

independent atom in nature, except noble gases. However, a group of atoms is found to exist together as one species having characteristic properties. Such a group of atoms is called a molecule. Obviously there must be some force which holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond. Since the formation of chemical compounds takes place as a result of combination of atoms of various elements in different ways, it raises many questions. Why do atoms combine? Why are only certain combinations possible? Why do some atoms combine while certain others do not? Why do molecules possess definite shapes? To answer such questions different theories and concepts have been put forward from time to time. These are Kössel-Lewis approach, Valence Shell Electron Pair Repulsion (VSEPR) Theory, Valence Bond (VB) Theory and Molecular Orbital (MO) Theory. The evolution ...

Atoms have parts, but are perfectly rigid. Electrons were first clearly identified in 1897, by J. J. Thomson. The most basic facts about atoms were elucidated over the following fifteen years or so. In particular: atoms consist of tiny nuclei containing almost all of their mass and all of their positive electric charge, surrounded by enough negatively charged electrons to make a neutral whole. Atoms come in different sizes, depending on the chemical element, but theyre generally in the ballpark of $10^{-8}$ centimeters, a unit of length called an angstrom. Atomic nuclei, however, are a hundred thousand times smaller. The paradox: How can such a structure be stable? Why dont the electrons simply succumb to the attractive force from the nucleus, and dive in. ...

The world around us consists of molecules that are composed of atoms. In Niels Bohrs atomic model, which is based on principles of quantum physics, electrons circle the atomic nucleus in different shells that contain a fixed number of electrons. The assumption was that attractive forces between the atoms in a molecule are the result of atoms sharing electrons to fill the electron shells. Beginning in the mid-1920s, Robert Mulliken applied quantum mechanics to the development of sophisticated models for the movement of electrons within a molecule, so-called molecular orbitals.. ...

Reggie Watts yodels, raps, hangs with woodland fauna, floats on a giant leaf and generally goofs around in a quartet of new videos from Greenpeace. The environmental group is sending a message to certain tech giants about using sustainable energy sources. Some of the Internets biggest and most innovative companies, such as Apple, Facebook and Google, are powering with modern, renewable energy, Greenpeace rep Dave Pomerantz told BusinessGreen. The #ClickClean movement expects the rest of the companies behind our online world, like Amazon and Twitter, to join them. No firms are named in the ads, which were created by The VIA Agency. We set out to develop a campaign that had humor at its core and that people would rally behind and share, said Via executive producer Mary Hanifin. Reggies unique brand of comedy, devoted following and ability to convey complex themes through humor made him a perfect fit. The comedian and musician has some experience with the clean-power issue, having ...

Understanding The Importance Of Dry Gas Scrubbers. It is a dry gas scrubber that you will need to use in order to make sure that all airborne gaseous contaminant will be removed. It is the factories households and buildings that use these devices. In almost all of the dry gas scrubbers, you will be able to see two processes that it creates. When talking about the first process, it is called as an adsorption. It is when adsorption is used that one substance is drawn and is stuck to the surface of the other. When there is a capturing of a molecule, then the term adsorption and adsorbate is present. The process of adsorption is made much easier the moment that the better material will use attractive force to overcome the kinetic energy if a gas molecule. The moment tat a smoker smokes inside his car, then adsorption can happen. It is the molecules if the smoke that will enter the interior lining of the car and that is also the reason that you will know that a person is smoking juts by entering ...

Adhesive pads of insects rely on wet adhesion caused by pad fluid [1-6] and have been repeatedly reported as having excellent attachment properties and high contact reliability [7-10]. In such wet adhesive systems, a liquid is squeezed out of tight contacts and builds bridges between two surfaces that are close to each other. The presence of pad secretion produced by specific epithelia in the contacts is crucial for generating strong attractive forces and therefore a strong friction [11,12]. Aside from van der Waals and Coulomb forces, attractive capillary forces mediated by the pad secretion are an important factor in the mechanism of insect attachment [12,13].. Insect pad secretion contains non-volatile, lipid-like components. Secretions in some insects are most probably emulsions containing water- and lipid-based components [7,12,14,15]. This indicates that secretions may serve various mechanical strategies in making contact. The beetle pad secretion was previously found to behave as a fluid ...

The world around us consists of molecules that are composed of atoms. Charting the bonds and positions of atoms in space is one of chemistrys fundamental missions. In 1893 Alfred Werner contributed to the understanding of molecular structures of inorganic substances - chemical compounds that do not contain carbon. According to Alfred Werner, the attractive forces are not connected to certain directions in the atom but emanate uniformly from the middle of the atom. With a new coordination number for an atoms bonds, he shed light on the structures of substances.. ...

Abstract: Seasonal variations of fatty acids were studied in the lipid fractions of the bivalve mollusk, Saccostrea cucullata, at the intertidal zone of Chabahar bay in the northern part of Oman Sea (Iran). Samples were collected in rocky shores between two stations. The analysis were carried by GC/MS chromatography. Thirteen fatty acids were identified, of which, the most important saturated fatty acids (SFA) were 14:0, 4, 8, 12 tri Me- 13:0, 16:0 and 18:0, the mono unsaturated fatty acids (MUFA) included 16:1n-9, 18:1n-9 and 20:1n-11, the polyunsaturated fatty acids (PUFA) were linoleic acid 9,12 18:2 , eicosapentaenoic acid EPA 20:5n-3 and arachidonic acid 20:4n-6.Variability of the fatty acid components were studied in four seasons. Maximum percentage level in Saccostrea cucullata for 14:0, 4, 8, 12 tri Me 13:0, 16:0 and 15:0 as saturated fatty acids was observed in summer, while for 18:1n-9, 20:1n-11 and 20:5n-3 (as unsaturated fatty acids) maximum concentration was observed in winter.

An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations as a subscript (aq). The word aqueous means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent as well as naturally abundant, it logically has become a ubiquitous solvent in chemistry. Substances that do not dissolve well in water are called hydrophobic (water fearing) whereas those that do are known as hydrophilic (water-loving). An example of a hydrophilic substance would be the sodium chloride (ordinary table salt). Acids and bases are aqueous solutions, as part of their Arrhenius definitions. The ability of a substance to dissolve in water is determined by whether the substance can match or exceed the strong attractive forces that water molecules generate between themselves. If the substance lacks the ability to dissolve in water the molecules form a precipitate. Aqueous solutions that conduct electric current efficiently contain strong ...

Test Procedure:. This water glass test in the boundary layer zones glass / water / air shows: that if the water level at the edge of the glass changes from a concave to a convex boundary, paradox movements of the free swimming objects occur on the surface of the water with a reverse change of direction of the table tennis ball and paper clip (pict. TT1). The compelling force of the swimming objects points to a electromagnetic repulsion-attraction force field (RAF=Lennard-Jones Potential), in which a quantum mechanicallly adapted formation of the water molecules to the boundary layer medium is created.. This test shows two essential properties of water for the maintenance of the biocybernetics of cells:. First: every boundary layer zone of a cell membrane provides a variable energy potential through the existing repulsive attractive force field (RAF) of water. Thus, three boundary layer zones with their own energy potential for signal amplification are created intracellularly between the DNA and ...

DNA in vivo is principally found in a highly condensed state within chromosomes, viruses, and bacterial nucleoids often packaged via multivalent cations. Despite the critical role that the condensed DNA in chromosomes plays on gene expression and DNA replication within eukaryotic cells, the dominant molecular forces which drive this condensation are not fully understood. In recent years, new theories have been proposed to explain DNA-DNA attractive forces which lead to condensation but experimental data capable of distinguishing between these theories has been sorely lacking. We have used osmotic stress coupled with small-angle X-ray scattering (SAXS) to probe the magnitude and dependence of the thermodynamic forces between condensed DNA helices.\\\\ This talk will be divided between two topics. In the first part, I will discuss force measurements on condensed DNA arrays in the presence of cations ranging from simple ions to complex real proteins. Using homologous polycations, we have measured ...

We see that H3 is an asymmetric structure. One electron, one proton and two neutrons, brought together by attractive forces, cannot combine volumetrically to form a symmetrically stable structure, and as a result, it is unstable and there are very few H3 atoms. Looking at the TRUE unit structure for H1, H2 and H3, we see that all three are bonded by electrical charge, but H1 has volumetric stability and 150 ג units holding it together; H2 has volumetric stability, more mass/energy units and fewer ג units than H1; and H3 has more mass/energy units and ג units, but no volumetric stability. This explains why H1 is the most abundant, H2 less abundant, and H3 correspondingly less stable. The atomic weights of the elements of the periodic table, in amu (atomic mass units), are actually the mean values of atomic masses calculated from a great number of samples. The accepted mean atomic weight for Hydrogen to four significant figures is 1.008. This includes H1 and all isotopes of Hydrogen. If all ...

Metallic bonding is the force of attraction between valence electrons and the metal atoms. It is the sharing of many detached electrons between many positive ions, where the electrons act as a glue giving the substance a definite structure. It is unlike covalent or ionic bonding.. Metals have low ionization energy. Therefore, the valence electrons can be delocalized throughout the metals. Delocalized electrons are not associated with a particular nucleus of a metal, instead, they are free to move throughout the whole crystalline structure forming a sea of electrons.. The electrons and the positive ions in the metal have a strong attractive force between them. Therefore, metals often have a high melting or boiling points. The principle is similar to that of ionic bonds.. The metallic bond causes many of the traits of metals, such as strength, malleability, ductility, luster, conduction of heat and electricity.. Because the electrons move freely, the metal has some electrical conductivity. It ...

Hooke, in terms of pure scientific achievement, really contributed almost as much to science (if such things are really quantifiable) as much as Newton, even though he is mostly remembered for one of his minor contributions, Hookes law of elasticity. Hooke had made substantial contributions to the field of optics (particularly through his epic book, Micrographia), and in planetary motion. In a series of letters about planetary motion, Hooke had suggested conceptual links between attractive forces and forces decreasing with the square of distance (the inverse square law that later became a foundation of the concepts of gravity that Newton mathematically proved). Hooke also had suggested at various times that planetary orbits could be elliptical (again, it took the mathematical genius of Newton to actually prove this), and furthermore, Hooke had also independently observed what are now famous as Newtons rings. Now, from all surviving accounts of Hooke (and there are few surviving accounts, the ...

Bioadhesion is the mechanism by which two biological materials are held together by interfacial forces. When relating this mechanism to the pharmaceutical sciences, mucoadhesion describes the attractive forces between a biological material and mucus or mucous membrane. Mucus membranes adhere to epithelial surfaces such as the gastrointestinal tract (GI-tract), the vagina, the lung, the eye, etc. They are generally hydrophilic as they contain many hydrogen macromolecules due to the large amount of water (approximately 95%) within its composition. However, mucin also contains glycoproteins that enable the formation of a gel-like substance. Understanding the hydrophilic bonding and adhesion mechanisms of mucus to biological material is of utmost importance in order to produce the most efficient applications. For example, in drug delivery systems, the mucus layer must be penetrated in order to effectively transport micro- or nanosized drug particles into the body. Mucoadhesion involves several types ...

Mutualisms are interactions between two species in which the fitnesses of both symbionts benefit from the relationship. Although examples of mutualism are ubiquitous in nature, the ecology, evolution, and stability of mutualism has rarely been studied in the broader, multi-species community context in which they occur. The pollination mutualism between figs and fig wasps provides an excellent model system for investigating interactions between obligate mutualists and antagonists. The fig pollination mutualism is exploited by a diverse community of non- pollinating fig wasps that develop within fig fruit at the expense of fig seeds and pollinators. Much less well studied, however, are consequences of the interaction between female pollinating wasps and their host-specialist nematode parasites. Here we focus on a tri-trophic system comprised of a fig (Ficus petiolaris), pollinating wasp (Pegoscapus sp.), and nematode (Parasitodiplogaster sp.), investigating geographical variation in the incidence ...

In a globular protein, the amino acid chain twists and folds in a manner that enhances the proteins solubility in water by placing polar groups of atoms at the proteins surface (where they can participate in attractive interactions with water molecules). This twisting and folding that determine the overall shape of a protein molecule (its tertiary structure) are due largely to the very complex interplay of intramolecular forces that exists among different groups of atoms within the molecule, and to intermolecular forces acting between groups of atoms on the protein and molecules in the proteins immediate surroundings. Some of the common amino acids have polar side chains; this polarity is the result of chemical bonds between atoms in these side chains that have very different electronegativities (for instance, oxygen and hydrogen). A proteins polar side chains tend to exert strong attractive forces toward other polar groups of atoms within the protein molecule, or toward polar molecules in ...

TY - JOUR. T1 - Environmentally friendly solvent- and water-based coatings for mitigation of crystallization fouling. AU - Al-Janabi, Abdullah. AU - Malayeri, M. Reza. PY - 2015/1/1. Y1 - 2015/1/1. N2 - The surface properties of solvent-based (SB) and water-based (WB) coatings and their impact on fouling during convective heat transfer of CaSO4 solutions were investigated. Experiments demonstrated that the SB coatings had generally better non-adhesive characteristics, especially at higher values of the electron donor component since the deposits could easily be washed away. For the SB coatings, a longer induction period compared to those of untreated surfaces was observed and a significant reduction of the fouling rate could be achieved. Further analysis of surfaces revealed that SB coatings enhanced the acid-base repulsive force and thus reduced the deposit/solid adhesion energy. For the WB coatings, the Liftshitz-van der Waals attractive force plays a decisive role in the adhesion process due ...

An electromagnetic attachment mechanism for use as an end effector of a remote manipulator system. A pair of electromagnets 15A, 15B, each with a U-shaped magnetic core with a pull-in coil 34 and two holding coils 35,36 are mounted by a spring suspension system 38,47 on a base plate 25 of the mechanism housing 30 with end pole pieces 21,22 adapted to move through openings in the base plate when the attractive force of the electromagnets is exerted on a strike plate 65 of a grapple fixture 20 affixed to a target object 14. The pole pieces are spaced by an air gap from the strike plate when the mechanism first contacts the grapple fixture. An individual control circuit and power source is provided for the pull-in coil and one holding coil of each electromagnet. A back-up control circuit connected to the two power sources and a third power source is provided for the remaining holding coils. When energized, the pull-in coils overcome the suspension system and air gap and are automatically de-energized

Signage apparatus having simple magnet-based structure for ease of modification - A readily modifiable modular sign apparatus is especially useful for fast food restaurants as backlighted menu boards in both indoor and outdoor applications. The apparatus comprises a preferably translucent substrate or mounting board which is preferably planar and has a front surface and a back surface. Precisely positioned holes are prepared at selected locations. These holes are formed to be aligned with thin metal shims which are affixed on the back surface of the mounting board and receive cylindrical magnets on the front surface. The magnets are attached directly to the rear of printed sheets, each of which may have wording or pictorial information or both. The magnets contact the metal shims through the mounting board holes, and are held firmly in position by virtue of both the magnetic attractive force and the shape of the walls of the mounting board holes. This magnet-based structure is also employed in ...

Another electron arrangement unique to the lanthanides series is that the 5s and 5p orbitals penetrate into the 4f-subshell. This has the effect that 4f-subshell electrons are not shielded from the increasing positive nuclear charge and that means that the attractive force makes the radii of their orbitals contract so they nudge closer to the nucleus. This means that the radii (physical size) of the lanthanide atoms actually decreases as atomic number increases. For example, the atomic radius of cerium (second lightest lanthanide, Z=58) is 2.70 angstroms across and the atomic radius of lutetium (heaviest lanthanide, Z=71) is just 2.25 angstroms. As proton number increases and radius decreases, the ionization energy (the energy you need to pull an electron into a higher energy shell or the energy released as it returns to ground state) increases, as you might expect. Increasing ionization energy means that outermost electrons are held more and more tightly to the atom. Density, hardness and ...

The Mesopsychidae is an extinct family of Mecoptera, comprising eleven described genera from Upper Permian to Lower Cretaceous deposits. In 2009, several well-preserved mesopsychids with long proboscides were reported from the mid Mesozoic of Northeastern China, suggesting the presence of pollination mutualisms with gymnosperm plants and highlighting their elevated genus-level diversity. Since that time, additional mesopsychid taxa have been described. However, the phylogeny of genera within Mesopsychidae has not been studied formally, attributable to the limited number of well-preserved fossils. Here, we describe two new species, Lichnomesopsyche prochorista sp. nov. and Vitimopsyche pristina sp. nov. and revise the diagnosis of Lichnomesopsyche daohugouensis Ren, Labandeira and Shih, 2010, based on ten specimens from the latest Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. After compiling data from these new fossil species and previously reported representative taxa, we conducted

The word with which the Surrealists tried to conjure so often, le merveilleux, belongs to a sustained attempt to find spiritual values in everyday life.. These, then, were the great attractive forces pulling Surrealism, and the whole D-S expedition, in three different directions: politics, science, and the spiritual. Though the Paris group held together for nearly two decades, it never achieved any complete synthesis or reconciliation of these forces. The dynamics shifted steadily both with the times and with the composition of the group. Such stresses help explain why it is difficult to discern the shape of the D-S expedition-its effort and its accomplishments. As I see it, substantial effort produced limited accomplishments in two respects. From Hugo Ball to Max Ernst to André Breton, the D-S expedition sought a redefinition and a reunification of mind in order to incorporate large segments of mental activity increasingly excluded by materialism (including Marxism). Secondly, they often tried ...

A depletion force is an effective attractive force that arises between large colloidal particles that are suspended in a dilute solution of depletants, which are smaller solutes that are preferentially excluded from the vicinity of the large particles. One of the earliest reports of depletion forces that lead to particle coagulation is that of Bondy, who observed the separation or creaming of rubber latex upon addition of polymer depletant molecules (sodium alginate) to solution. More generally, depletants can include polymers, micelles, osmolytes, ink, mud, or paint dispersed in a continuous phase. Depletion forces are often regarded as entropic forces, as was first explained by the established Asakura-Oosawa model. In this theory the depletion force arises from an increase in osmotic pressure of the surrounding solution when colloidal particles get close enough such that the excluded cosolutes (depletants) cannot fit in between them. Because the particles were considered as hard-core ...

The universe is very far from maximizing its entropy. Most egregious is the gravitational state of the universe, as noted years ago by Penrose. Gravity, being a long range, unscreened, attractive force, maximizes its entropy by clumping. This is quite unlike systems with ordinary interactions (generally of limited range, or subject to screening), whose entropy is maximized when matter and energy are uniformly distributed. In the case of gravity the most entropically dense configurations are black holes, with exp(A) microstates (A is the area in Planck units). Why did the big bang begin with a smooth background metric, instead of an agglomeration of black holes, when the latter has much higher entropy and hence occupies an exponentially larger portion of phase space? We explore how a phase transition between the smooth, low entropy spacetimes and the high entropy black hole phase might occur ...
