My Intangible Orb of Dreams: An ADHD Introspection

I wrote this piece for my first open mic poetry performance to share my experiences as a late-diagnosed ADHDer. Throughout college, I have struggled to keep up with expectations placed on me that felt unrealistic and unfulfilling, while also learning how to be my most authentic self. I long to find my own version success through embracing my neurodiversity even if I don\u27t meet the standards that society places on me. I am reminding myself, and you, that I am not dysfunctional at all, I’m simply wired to spend energy on things that truly fulfill my purpose here. It might not be right or enough, but at least it’s true

Fluoride Adsorption onto Soil Adsorbents: The Role of pH and Other Solution Parameters

Soil adsorbents continue to attract increasingly high numbers of researchers in water defluoridation studies. An aspect of solution parameters, that is the aqueous adsorption of fluoride onto soil adsorbents in defluoridation studies, has been reviewed and reported. The pH was found to be the main factor controlling fluoride adsorption on the popular soil adsorbents including: aluminosilicates, iron (hydr)oxides, aluminum (hydr)oxides, apatites, carbonaceous minerals, calcareous soils and zeolites and the other key parameters being temperature, time of contact, and co-existent ions. Fluoride adsorption onto metal-exchanged zeolites and hydroxyapatites (optimum pH = 4–10), iron (hydro)oxide minerals (pH = 2–7), and carbonaceous minerals (pH = 4–12) is relatively pH-independent, and high amounts of fluoride are able to sorb upon the surfaces of these minerals in a wide range of pH values. However, montmorillonites (optimum pH = 5–6), aluminum (hydro)oxide minerals (pH = 5–7), and calcareous minerals (pH = 5–6) only sorb significant amount of fluoride in a narrow range of pH values. The fluoride adsorption onto the latter class of minerals, also generally occurring at slightly above room temperatures, appears to be highly specific and not strongly affected by the presence of coexistent anions including: PO43−,SO42−,Cl−,andNO3−

The Uses of Anger

Racism. The belief in the inherent superiority of one race over all others and thereby the right to dominance, manifest and implied. Women respond to racism. My response to racism is anger. I have lived with that anger, on that anger, beneath that anger, on top of that anger, ignoring that anger, feeding upon that anger, learning to use that anger before it laid my visions to waste, for most of my life. Once I did it in silence, afraid of the weight of that anger. My fear of that anger taught me nothing. Your fear of that anger will teach you nothing, also. Women responding to racism means women responding to anger, the anger of exclusion, of unquestioned privilege, of racial distortions, of silence, ill-use, stereotyping, defensiveness, misnaming, betrayal, and coopting

Atomic Collisions of Low Relative Velocity

Approximate solutions for the excitation of an atom by a colliding charged particle, developed as perturbations of the state of the system at infinite or asymptotic sepa­ration of atom and particle and also as perturbations of the state of the system at vanishing velocity of relative motion, are extended, in the impact parameter form (suit­ able to collision of heavy particles), to include the inter­action of states that are degenerate at asymptotic separa­tion, and to obtain thereby a condition for the Born approxi­mation that depends on the phase relations of degenerate states in the collision and excludes the low velocity region to the Born approximation, except for the excitation of S states. This is a correction of previous theories, which conclude that the Born solution is a general approximation at low velocities for weak interactions. A low velocity perturbation solution is established in terms of the stationary states of the system and developed to show that, at sufficiently low velocity of relative mo­tion, the atomic states are coupled to the moving particle in the range of interaction. Differences in coupling energy affect the coherence of asymptotically degenerate states in the collision and influence the orientations of final excited states.</p
