“When the divine vision is attained, all appear equal; and there remains no distinction of good and bad, or of high and low.” - Sri Ramakrishna Paramhansa

The Eye of Shiva Talon Abraxas

When the Fourth (Race) arrived at its middle age, the inner vision had to be awakened, and acquired by artificial stimuli, the process of which was known to the old sages.... The third eye, likewise, getting gradually PETRIFIED, soon disappeared. The double-faced became the one-faced, and the eye was drawn deep into the head and is now buried under the hair. During the activity of the inner man (during trances and spiritual visions) the eye swells and expands. The Arhat sees and feels it, and regulates his action accordingly.... The undefiled Lanoo (disciple, chela) need fear no danger; he who keeps himself not in purity (who is not chaste) will receive no help from the "deva eye."

- The Secret Doctrine

The priceless gift of spiritual vision veiled in the arcane symbolism of the Eye of Shiva is the sacred heritage of future humanity, but it will remain hidden, like the Biblical treasure in the field, until all lesser lights are renounced. From the time of the sacrificial descent of the Agnishwatha Pitris into the Monadic Host of incipient humanity over eighteen million years ago, the fiery spark of noetic insight has been enshrined in the inmost heart of each and every immortal soul. In the earliest epochs of evolving humanity, the light of soul-vision irradiated and suffused the mortal vestures, giving meaning and direction to daily conduct, a fullness of fellow-feeling in society, and grateful reverence to the lustrous presence of spiritual elders and teachers. The spontaneous devotion of the Third Root Race sprang from its lucid awareness of the supernal light within the human breast, and its natural intention to cherish and consecrate that living trust. Effortless purity and exquisite delicacy of soul-etiquette, qualities so scarce in the present age, were the widely prevalent marks of undefiled self-consciousness in the earliest races. The light has not wholly dimmed nor has the vision vanished beyond recall.

The indestructible Light of the Logos antedates all worlds and endures as the permanent possibility of vision. The sacred organ of spiritual perception in man has become obscured and even atrophied through misuse of its potency. By misappropriating the universal energies of the Higher Triad for the sake of the separative concerns of the mortal self, the vital connection between the permanent and impermanent vestures was damaged, dulling the psycho-physical senses, rendering them fickle and deceptive at best. As the final consequence of follies and misdeeds, the crucial brain-centres associated with the channels of spiritual awareness were petrified.

The diminished estate of contemporary humanity is the direct and inevitable consequence of its individual and collective immorality in the past. Most of the world's present ills and sufferings, along with its apparent indifference to its future welfare, can be traced to deliberate if forgotten choices in distant eras. Like Milton's Samson, shorn of power and blinded through folly, mankind is helplessly chained to the cyclic round through no fault but its own. Similarly, if it is to recover the lost light of its spiritual immortality, this can only come about through sacrificial deeds of self-regeneration and self-correction, thus emulating the mighty Yogin, Shiva. Gupta Vidya teaches the mysterious tenet that the Third Eye is indissolubly connected with Karma, a teaching which is as telling in relation to the future as it is pertinent to the past. Both past and future are merely facets of the eternal present viewed from the standpoint of differentiated consciousness. So too, cause and effect in discontinuous action are but aspects of universal harmony in manifestation through centrifugal and centripetal modes of motion. In the Bhagavad Gita neither the Divine Eye of Krishna nor the Cosmic Vision that it confers is fanciful or fortuitous. The Avataric descent of the Logos and the lending of the Divine Eye to Arjuna are objective representations in the temporal realm of archetypal realities in the timeless realm of spirit. It was Arjuna who, through self-righteous identification with his own mask, placed limits upon Lord Krishna and thereby felt himself cut off from immortality. Having truncated the sense of self, he alienated himself from the Logos, and fell into dark despair when faced with his self-chosen dharma.

If ignorant identification with the mask is the primary cause of human bondage, it is inseparable from a correlative caricature of Deity and Law. There is an intimate connection between anthropomorphic religion and the exteriorized personification of universal law as a cruel and avenging power. In regard to the Greek conception of Nemesis, H.P. Blavatsky pointed out that originally Nemesis was not a goddess, but rather a moral feeling which stood as the barrier to evil and immorality. Through anthropomorphizing fancy, this feeling was progressively externalized and personified into an ever-fatal and punitive goddess. Such an unphilosophical conception, itself a symptom and result of the corruption of consciousness, must be rejected in order to restore a sterling sense of responsibility under Natural Law.

Karma has never sought to destroy intellectual and individual liberty, like the God invented by the Monotheists. It has not involved its decrees in darkness purposely to perplex man; nor shall it punish him who dares to scrutinise its mysteries. On the contrary, he who unveils through study and meditation its intricate paths, and throws light on those dark ways, in the windings of which so many men perish owing to their ignorance of the labyrinth of life, is working for the good of his fellow-men. - The Secret Doctrine

[the-framed-maelstrom]

The eternal return does not produce the same but constitutes the happening of being as unconcealment through differentiation. It is not a recurrence of identical beings but the repetition of difference, where being is enacted in its ownmost disclosure. This repetition does not merely conserve but transforms, setting forth a superior form in the unfolding of historical Dasein​. Negation in eternal return functions as a Nachfolge, a following-after that does not destroy but rather enables being to overcome itself through its own grounding confrontation. It is not a dialectical negation but a clearing away—a letting-be that casts out all that lacks essential grounding in truth. Thus, negation here is not reactive but a preparatory movement that eliminates all that cannot withstand the event of unconcealment​. The essence of eternal return does not lie in memory but in letting vanish, in an active forgetting that clears away the derivative, the inessential, and all that is not gathered into the ground of truth. This is not a return to what has been but a projection of being in its most radical self-opening. The centrifugal force of eternal return is the force of disclosure, expelling all that is inessential, all that cannot stand in unconcealment. It is the movement of historical Dasein toward its ownmost destining, wherein truth is not a given state but an event that continuously happens through struggle.

tried making a gquuuuuux themed physics problem. when i tried solving it i ended up in the depths of algebra hell. here's the final version of the problem. good luck

Machu lives in a space colony, the interior of a cylinder 6.4km in diameter. In order to simulate gravity, it spins once every 113.5 seconds, generating a centrifugal force that is extremely close to Earth's gravity. One day, the system malfunctions and the rotation slows down massively. Machu jumps vertically (perpendicular to the ground) with an initial velocity of 1m/s, and finds that she has shifted exactly 10cm when she lands. How long does a rotation of the colony take now? Neglect air resistance and approximate to the first 3 significant figures. Online tools may be used.

i'm going to make an easier problem after this. notes on this one under the cut, and a solution at the end

when i say online tools may be used i mean online tools MUST be used do NOT DO THIS MANUALLY FOR GOD'S SAKE

there are two approaches to this problem. both of them suck major ass

the first, the route i was first planning to go down, was using coriolis and centrifugal forces. instant roadblock, before i even got to the coriolis part the centrifugal force hit me with a stupid differential equation that requires the error function to solve

the second, the backup route, was linear. it involves trigonometry and stuff, but that's not the bad part. the bad part is that the final equation you end up with for the angular velocity looks like absolute shit, has no easy aproximations, and gets even worse when you plug it into wolframalpha for the exact solution. like.

at least it's closed form i GUESS

anyway just. approximate it. use newton-raphson or something. i don't care

here's my full solution. enjoy

Would you write any flirtatious chase-cameron banter? Preferably set at a late night in the hospital after everyone's gone home and they're stuck doing labs, looking after a patient and they're a teensy bit delirious so it's weirdly also very honest and vulnerable.

anon i bet you thought i forgot about this req didn't you. NEVER FEAR. this actually took me a while to figure out what to do with (i love writing banter but flirtatious banter is scary especially for a 'new' fandom) (i still consider myself new to this fandom) but here we go. set vaguely during a non-specific part of fwb era--if pressed i'll say between 3x15 and 3x16, but the details are not relevant lol:

House, of course, leaves PPTH at 5pm on the dot with strict orders to keep running lab stains and PCR tests on their latest patient until they get a positive result. “Not like you three have anything better to do,” he calls over his shoulder, while Foreman rolls his eyes and Chase tries to catch Cameron’s eye. She’s not paying attention–too busy adjusting her glasses tiredly while she peers into a microscope, hair ruffled in a way that reminds him of her rolling out of his bed that morning–and Chase tells himself he’s not disappointed. They’re not together. It’s just sex. It shouldn’t matter that they had half-formed plans to get Indian takeout and play a drinking game while watching old episodes of General Hospital together that was almost definitely going to lead to–

“Alright, I’m out,” Foreman declares at midnight. “This isn’t fair, I wore the beeper last night. One of us needs to be awake for the differential tomorrow.” “Nice excuse,” Chase mutters darkly. “You mind bringing us up some coffee from the cafeteria before you go, Judas?”

“That’d be great,” Cameron adds, all faux-earnest charm, and Foreman actually has the grace to look a little bit guilty at that. He leaves the coffees on the lab benches–definitely not best practice, but nor is making three overworked doctors run labs all night–and leaves with the promise to relieve them at 6am if they come up with no further answers. Chase, of course, doesn’t believe him for a second, but this seems to pacify Cameron; she shoots him a suspiciously sunny smile, and wishes him good night.

As soon as Foreman’s out the door, she says, “And then there were two.” “And then there were two,” Chase echoes, eyeing her warily from where he’s waiting for the centrifuge to recalibrate. “Not quite what I meant when I asked if you wanted to hang out tonight.” That’s usually how they put it, in public–do you want to hang out later? Wanna grab some dinner? It’s really more for Chase’s sanity than Cameron’s; she seems unusually blasé about the whole friends-with-benefits situation, which is fine, honestly, but is it so crazy to just want to keep things to themselves for a while? To not want the hospital gossip mill offering their opinion on what is, objectively, a private decision between two consenting adults? And it’s not like Chase knows how to phrase it any other way. Cameron, if she had her own way, would keep being forthright about it: want to have sex later? Cool. Collected. And it isn’t that Chase has an issue with it, exactly. It’s just as she said it would be, after all. No strings attached. Easy peasy. But there’s just something so clinical about it. It feels strange, especially from Cameron, who he always assumed would be the flowers-and-dinner type.

“We could,” Cameron says now, pushing back her chair and spinning to face him. “If you wanted.” “You don’t mean,” Chase starts, fighting his flush at the thought of Cameron and sex and the fucking pathology lab, and Cameron grins from ear to ear.

“Hang out,” she finishes, simple and guileless. “I guess we’re doing it anyway, right? No harm in taking a quick break to chat.”

“That is not what you meant,” Chase accuses. God, she would probably kill him for thinking it, but there really is something beautiful about Cameron in the lab. Even when she’s exhausted and frustrated there’s a part of her that just lights up when given a microscope and a set of slides, like she’s some overeager freshman biology major donning a lab coat for the first time. It’s lit up right now: in the slightly manic gleam in her eye, in her rolled-up sleeves, in her glasses set half-askew on the edge of her nose. “Anyway, we don’t have time to chat. Unless you’re planning on being trapped in here with me all night.”

“And that would be so terrible,” Cameron hums, dangling her legs invitingly. She’d kill him for thinking this, too, but at this precise moment she seems so…normal. Not normal as in ordinary, quotidian, but normal as in not a woman with dead-husband-levels of hang-ups around relationships; normal as in the kind of woman Chase thinks he knows how to flirt with. It’s an illusion, but it’s almost like he could step right between the open vee of her legs and grin down at her teasingly, and almost like she would let him. 

Not that he wants to. Not that she would let him. It’s just sex. Just convenience. Just…microwave pizza.

“So very terrible,” Chase agrees, turning back to the centrifuge so he doesn’t have to keep looking at her and thinking about it. “Good thing we’re not actually locked in together.” “That could probably be arranged,” Cameron says. He can’t see her anymore, but he imagines her smiling again, polishing her glasses on the edge of her coat and her bangs falling into her eyes, the way she looks at him sometimes when they’re walking out to her car together on the way out of work and their fingers accidentally brush together and Chase can pretend that she’s thinking about holding his hand. He thinks that’d be nice, sometime. Just holding Cameron’s hand–not out of any hidden romance, but just for the sake of it. He knows her hands so well, the cracked-dry knuckles and fingertips from scrubbing them multiple times a day and the faintly oily, lavender-scented sheen of her hand cream that always sticks to her palms, and she always holds his face, his shoulders, his hips, but never his hands. “Get someone to call in a bomb threat.” “Call in our own bomb threat,” Chase raises weakly.

“Pretend I’m holding you hostage.” “Hey, why are you holding me hostage?” Chase demands, glancing at her over his shoulder in an accusatory fashion. “I’m the man!”

“I’m a femme fatale,” Cameron smirks, “and you were the one who said we didn’t have time to chat.”

Their pagers go off then; their patient is coding. By the time she’s stable, House is harassing them via speakerphone about test results and his latest epiphany, and it’s like the hours in the lab never really happened. By the time Foreman slinks back in, arguably in a worse mood after two hours’ sleep than he’d be if he’d never slept in the first place, the silly lab banter has entirely slipped from Chase’s mind while Cameron gnaws frustratedly on her bottom lip, and he isn’t thinking about it at all.

Honestly. He isn’t.

Hey everyone, time for a long overdue update!

Combustion Engines - Not Ready Just Yet

By this point, I was hoping to have combustion engines done. I tried a purely physics based approach, using separate cylinder, piston, con-rod, & crank rigidbodies, and applying a force to the piston based on the current angle of the crank. This worked reasonably well, but had problems with "phantom forces" whereby the engine got torque applied to it, sometimes flipping over the vehicle it's in. Also, using physics for all the parts like this has RPM limitations, and doesn't scale that well for sim performance.

So I've decided to change tack slightly, I still want to keep the appearance of the moving parts (i.e. pistons and con-rods), but my plan is now to procedurally animate these in code. There's not really any need to use physics as these parts can't collide with anything when inside an engine. To apply torque to the crankshaft, I'm working on something similar to the electric motors, but with a different torque curve.

Hopefully I'll be able to get this done soon, but in the meantime I thought it would be good to get a small update out. Here's what's in it…

Parts

There are now some slider versions of the 1-Hole and 2-Hole connectors, some new "angle axle" connectors, and a larger centrifugal clutch.

Also, the rounded beams can now be resized one unit smaller than before.

Part Behaviours

I've improved how the invert option works for parts with a single key bind (e.g. brakes), adding a separate invert option for the joystick axis.

You can now type in values for any part behaviour slider, by right clicking it. Even values beyond the normal slider range can be entered (but no guarantees the physics won't blow up with higher RPMs or torques!)

No Collide Tool

For those who want to bypass part collisions in their builds, I've added a new "PartCollision" script mod tool that can be used to disable part collisions. Parts with their collision disabled will still collide with the ground, but nothing else.

Here are the full release notes:-

New parts:-

"1-Hole Slider" and "2-Hole Slider" connectors.

Angle axle 90, 180, 3 x 90, & 4 x 90 connectors.

Centrifugal clutch x3.

Rounded and half rounded beams can now be resized one unit shorter.

Added "invert axis" option to part behaviour joystick axis settings.

In brake, clutch, and differential part behaviours, replaced "invert direction" option with "invert control", which properly inverts their control behaviour.

By right clicking a slider in the part behaviour settings, it's value can now be edited by typing in a number.

Shortcuts (Ctrl+C and Ctrl+V) for copy and paste in part behaviour settings.

A construction can now be unfrozen (via the construction UI) while the player is seated in it.

Lowered minimum mouse sensitivity values.

Added methods to IConstructionOperations to set whether parts are collidable (and added IsCollidable property to IPart interface).

Added new PartCollision script mod.

Bug fixes.

Upgraded to Unity 2021.3.34.

🎯 Does Closing the Discharge #Valve in a Centrifugal Pump Reduce Motor Load?

In the world of industrial pumping, one of the common misconceptions is that closing the discharge valve in a centrifugal pump increases the load on the motor. But in reality, the opposite is true.

When the discharge valve is closed, the pressure on the pump rises — that part is correct. However, what might surprise many is that the motor draws less current. So, how does that make sense? Actually, it’s not only normal — it’s a well-understood and purposeful phenomenon used in many pumping operations.

🔍 What’s really happening?

In this scenario, the liquid cannot flow through the pump. A high-pressure zone builds up at the impeller outlet, preventing further discharge. Part of the kinetic energy imparted by the impeller is forced back toward the impeller’s suction eye. As a result, the pressure differential across the impeller blades decreases.

Here’s the key:

✅ When the pressure differential is reduced, the hydraulic resistance on the impeller drops. Consequently, the impeller rotates with less mechanical resistance, and the motor requires less torque — leading to a lower current draw.

This is precisely why, for large-capacity pumps, operators often start the pump with the discharge valve fully closed. Doing so minimizes the inrush current during startup, and the valve is then gradually opened until full operation is reached.

⚠�� Note: This technique should only be used when approved for the specific pump type, and the shut-off pressure must remain within the safe operating range defined by the manufacturer. Prolonged operation under shut-off conditions may lead to overheating or cavitation.

💡 From our hands-on experience at Advanced Pumps, understanding this behavior is not just theoretical — it’s a key factor in ensuring safe, efficient, and energy-conscious pump operations across large-scale projects, from water treatment plants to firefighting systems.

📌 Field Engineer’s Tip: Always make sure operating teams know when and how to use the discharge valve as a startup tool — not as a permanent flow control method. Train your operators to observe motor behavior during startup and shutdown phases — it’s a crucial step toward protecting your equipment and saving energy.

Details of basic cell culture methods and operation steps

Preparations for receiving cells

1. Recording Key Cell Information

When receiving a cell line in the lab for the first time, several pieces of information related to the cell line should be organized and recorded. These details are crucial for ensuring successful cell propagation, expansion, cryopreservation, and storage. It is strongly recommended to document the following information before starting cell expansion: (1) Background information (2) Subculturing (3) Cryopreservation (4) Cell line storage.

Table 1. Information to Record Regarding Cell Lines[1].

During cell culture, continuous cell lines may undergo changes. Numerous studies have demonstrated the various effects of long-term culture on the morphology, development, and gene expression of cell lines, such as variability in cell growth, leading to cell contamination and other issues. Therefore, it is crucial to establish a seed stock of low-passage cells when the cell line is first received in the laboratory.

2.Morphological Observation of Cultured Cells

Monitoring and recording the morphology and behavior of cells is crucial. It is recommended to routinely and carefully examine cultured cells before subculturing to assess their status and health. Observations of cell morphology can help researchers determine:

(1) Cell morphology: Are the cells healthy or deteriorating (such as cellular senescence or necrosis)?

(2) Is there any evidence of contamination?

(3) Differentiation of cell types and assessment of cell density.

Most cell cultures grow in either suspension or adherent conditions. However, in some cases, a mixed population of suspension and adherent cells may be observed.

Table2. Cell culture growth type.

Based on morphology, cultured cells can be classified into three basic categories: fibroblast-like, epithelial-like, and lymphoblastoid-like.

Figure 1. General Characteristics and Morphologies of Cultured Cells[1].

The specific operation of receiving cells

Using a T25 culture flask as an example. First, check the color of the culture medium and inspect for any leakage. Then, observe the cell condition under an inverted microscope and capture images at different magnifications to rule out contamination or poor cell condition. After confirming the cells are in good condition, disinfect the outer surface of the cell flask and place it in the incubator for a few hours (depending on cell density) to stabilize the cell state.

Adherent cells: When the cell growth density exceeds 80%, passaging can be performed as needed. If the confluence is less than 80%, perform a partial medium change by removing half of the original medium and adding an equal amount of fresh complete medium. Continue culturing until the cell density exceeds 80%, then proceed with passaging.

Suspension cells: Transfer the liquid from the culture flask to a centrifuge tube and centrifuge at 500g for 5 minutes. Gently discard the supernatant. Resuspend the cell pellet at the bottom of the tube in 10 mL of complete medium by gentle pipetting. Transfer the suspension to a new culture flask and incubate overnight. Perform subculturing based on cell density and growth status.

Cell counting: Dilute the cell suspension to 200-2000 cells per milliliter in a serum-free medium. Add an equal volume of 0.4% trypan blue solution to 10-100 µl of the cell suspension. Mix gently and count the cells using a hemocytometer. Living cells can reject trypan blue and remain translucent, while dead cells will be stained blue. It is also more convenient to directly use a cell counter for counting.

Figure 2. Trypan Blue Staining Image[2].

Selection of Appropriate Cell Culture Media

Selecting the appropriate culture medium is crucial for the success of cell culture. Different types of cells have varying growth requirements and specific culture conditions. First, the nutrients in the culture medium are essential for maintaining cell growth and metabolism. Different types of cells require various amino acids, sugars, vitamins, inorganic salts, lipids, and other nutrients to meet their physiological needs. If the culture medium lacks necessary nutrients, cells may be unable to grow and divide normally, and this can even lead to cell death[3][4].

When selecting the appropriate culture medium, prioritize the culture conditions provided by the cell source company. If the source is uncertain, you can refer to the recommended medium for the corresponding cell type from ATCC.

Table 3. Common cell culture systems.

Secondly, growth factors and hormones in the culture medium play an important role in regulating cell growth and differentiation. These growth factors can promote cell proliferation, development, and differentiation, and play a key role in cell signaling pathways. Different types of cells require specific growth factors and hormones to maintain their particular functions and characteristics. For example, neurotrophic factors are often added to the culture medium for neural cells to promote growth and synapse formation; fetal bovine serum is commonly added to the medium to provide the growth factors, proteins, and other essential components needed by the cells.

In addition, antibiotics can be added when necessary to prevent contamination and protect the cells. For example, double antibiotics (penicillin/streptomycin) or even triple antibiotics (penicillin, streptomycin, amphotericin B) can be used to inhibit the growth of microorganisms such as bacteria and fungi. Penicillin-streptomycin is effective in inhibiting the growth of most Gram-positive and Gram-negative bacteria, while amphotericin B can be used to prevent fungal and yeast contamination.

Cell Passage Operation Steps

Over time, the number of cells will increase, but space and resources are limited. Therefore, when cells reach a certain density, it's time to provide them with a larger living space to continue proliferating.

Figure 3. Passaging Workflow Diagram.

Using a T25 culture flask as an example, the common steps for cell passaging are as follows:

(1)Remove the cells from the incubator and observe them under a microscope. If the confluence exceeds 80%, proceed with passaging.

(2)Preparation: Prewarm the culture medium and PBS in a 37°C water bath. Place the consumables needed for passaging (e.g., pipettes, pipette tips, T25 culture flasks) in a biosafety cabinet, sterilize them with UV light for 30 minutes, and ensure proper ventilation. Disinfect the trypsin, prewarmed medium, and PBS with 75% ethanol before placing them in the biosafety cabinet.

(3)Aspirate the old culture medium from the flask, rinse the cells with 5 mL of PBS, and then aspirate the PBS.

(4)Add 1 mL of trypsin, gently shake the flask to ensure the trypsin fully covers the cells, and incubate it in a 37°C incubator for 30 seconds to 2 minutes (the actual incubation time may vary depending on the cell line used).

(5)Observe under a microscope, and when ≥90% of the cells have detached, add a volume of complete medium containing serum equal to twice the volume of the trypsin to stop the digestion. Pipette the surface of the cell layer several times to disperse the cells into a single-cell suspension.

(6)Centrifuge at 500 g for 3~5 minutes, then resuspend the cell pellet in complete medium containing serum.

(7)Distribute the cell suspension into culture flasks according to the desired passaging ratio, add fresh complete medium, gently shake the flask to evenly distribute the cells, and label it accordingly.

(8)Observe the cell density and condition under a microscope, then return the cells to the incubator. When using trypsin for passaging animal cells, several factors need to be considered. Trypsin has proteolytic activity that can affect various physiological and metabolic functions of the cells.

Tips: The Best Method for Passaging Cells Using Trypsin

Before adding trypsin, wash the cells with Ca2+ and Mg2+-free saline/PBS to remove these ions (Ca2+, Mg2+ and serum in the solution can reduce trypsin activity).

Use the lowest concentration and volume of trypsin to detach cells from the surface of the culture flask.

If possible, use the trypsin solution at room temperature or lower to reduce enzyme endocytosis.

Use trypsin to treat the cells for the shortest time possible to avoid over-digestion, which may affect the cells.

Use trypsin inhibitors, such as complete medium containing serum, to neutralize and terminate trypsin activity, then centrifuge to remove the trypsin.

After the cells have detached, immediately centrifuge to remove the trypsin from the surface of the culture flask.

CN- + Sx2- -> SCN- + Sx-12-

6 SCN- + Fe3+ -> [Fe(SCN)6]3-

Result: blood red complex. Disturbance: SCN-, NO2-, I-, Co2+

Calcium <--> Oxalate (also Barium)

Barium <--> Carbonate (also Calcium)

Ba2+ and Ca2+ can also be felled with H2SO4 (sulfuric acid) though the solubility of BaSO4 is lower, so it'll fall out at lower concentrations.

Fell reactions based on S2- concentration is also the principle between differentiating the H2S and the (NH4)2S groups.

H2S <--> 2 H+ + S2-

Therefore, the concentration of S2- ions will be lower the higher the concentration of H+ ions is (chemical balance), and it'll be higher if the H+ concentration is lower, directly correlating the concentration of S2- and the pH value.

Since the H2S group requires a lower concentration of S2- to be felled, this reaction is done at acidic pH. After seperating the H2S group, the exact same process is repeated at a basic pH to fell the (NH4)2S group.

Set pH value with according puffer. (Plain HCl for H2S group, NH4Cl/NH3 puffer for (NH4)2S group)

Add a pinch of TAA, which will, regardless of the pH value, react to H2S, Acetate, and Ammonium together with water

Cook for 10mins. Be careful to not dry out the entire substance or else it will fucking suck later so bad

Filter or centrifuge. Profit

Filtrate: contains not felled cations to be used for undisturbed proof

filter remains: contains felled cations that need to be oxidized into soluble form for further proofs

the KTG hates you and wants you dead. yes you need more hydrogen peroxide. good fucking luck cooking that shit out again. on god, just fell out the iron as berlin blue. who give a shit, cyanoferrat isnt in the analysis anyways. The worst ions are just iron and copper. Get those bitches gone and you're golden.

And ig if you dump in Silvernitrate and it remains clear also cry tears of joy cuz you just eliminated all halogenides, aka the big whores of the anion world. god bless. iodid is the best one to figure out from em i think tho. if u just got iodid it's probably chill.

“Love, that moves the sun and the other stars” ― Dante Alighieri, Paradiso The Great Central Sun Talon Abraxas Where is the birthplace of the radiant sun that the Greeks rose to meet at dawn with a kiss upon their upraised hands? From whence came Helios, son of Hyperion, "The High Going", and Euryphaessa, "The Far Shining"? What is the source of the light that shines from Loka Chakshu, the Vedic Eye of the World?

The Egyptians symbolized the birth of the sun through descriptions of the infant sun god Horus, who arose from within the petals of a sacred blue lotus floating upon an endless sea. This sun was the Eye of Ra, the "good eye of heaven", as the Samoyeds say. The idea of the eye of God was and is very widespread in the world. The fact that many people have conceived of the sun as both a youthful hero and an aged father merely suggests the cyclic rebirth of the orb's penetrating gaze.

Loka Chakshu or Surya is depicted in the Vedas as the Godhead of Supreme Truth and Knowledge, the Lord of Light. His two functions are luminous vision and luminous creation, suggesting that the vision of Truth and Knowledge is followed by the creation of Light. The medieval alchemists spoke of the sol niger, the black or invisible sun, which they related to prime matter and the unconscious. The visible sun is at the nadir, out of which depths it must ascend towards its zenith, the invisible apex that oversees the creation of light. "Chaos ceases at the effulgence of the Ray of Primordial Light helped on by the Word of the Central Sun." During the active periods of being, this central, invisible source gives rise to a stream of ceaseless energy whose vibrating currents become more active at each descending rung of the sevenfold ladder of being. The equinoxes and various other cyclic phases and periods of the visible solar course are only symbols of the singular truth which remains hidden. The activity of this energy, increasingly involuting into gross matter, can be seen as a demonstration of numerical patterns which are arcane hieroglyphs containing the keys that yield an ever greater abstract knowledge of solar reality. The Secret Doctrine describes the Central Sun as an unseen point in sidereal space which constantly attracts our solar system. It is the Centre of Rest to which all motion is ultimately referable. It is the "reservoir within which divine radiance, already differentiated at the beginning of every creation, is focussed". This focal point is everywhere and yet – like the Logos – it is somewhere. As the earth is attracted to the sun in our solar system (though obviously the centripetal forces in the system are counterbalanced by the centrifugal), so our sun is a servant to a more remote centre around which it revolves. One may imagine increasingly expanded systems ultimately resolving themselves within a solar centre which encompasses all but which exists on an inconceivably homogeneous plane of matter. One may analogically imagine all systems resolving themselves into an essential, primordial point in endless space. In our cogitations, we are wise to remember the admonition that not even the Dhyan Chohans can penetrate the mysteries of the boundaries separating the milliards of solar systems from the Central Invisible Sun.

Hand Joint Pain Treatment for Arthritis: What Works Best?

Introduction

Hand joint pain is a common and often debilitating condition, particularly in individuals diagnosed with arthritis. Whether it's osteoarthritis due to age-related cartilage degeneration or rheumatoid arthritis caused by an autoimmune response, chronic hand pain can severely impact daily life. In recent years, new developments in regenerative medicine and non-invasive techniques have revolutionized hand joint pain treatment, especially in cities like Hyderabad where access to cutting-edge care is expanding rapidly.

Understanding Arthritis in the Hands

Arthritis in the hands typically affects the joints at the base of the thumb, the middle joints of the fingers, and the joints closest to the fingertips. Symptoms often include:

Persistent pain and stiffness

Swelling and tenderness

Decreased range of motion

Warmth around the joints

Joint deformities in advanced cases

Conventional treatments like anti-inflammatory medications, corticosteroid injections, and physical therapy may help in early stages. However, for chronic sufferers, especially those seeking non-surgical hand pain treatment in Hyderabad, newer biological therapies offer promising alternatives.

Stem Cell Therapy for Hand Pain

Stem cell therapy for hand pain is a groundbreaking regenerative technique that uses the patient’s own stem cells to repair damaged tissues in the hand joints. These cells have the ability to differentiate into cartilage and bone, making them ideal for arthritis-related degeneration.

How It Works:

Mesenchymal stem cells (MSCs) are harvested from bone marrow or adipose tissue.

These cells are processed and injected directly into the affected hand joints.

Over time, the stem cells help reduce inflammation, repair joint cartilage, and improve function.

Benefits:

Minimally invasive

Natural healing from within

Reduction in pain and stiffness

Delay or elimination of the need for surgery

In recent years, Stem cell therapy for hand pain has gained traction among patients in Hyderabad looking for lasting, non-surgical relief.

PRP Therapy for Hand Injuries

Another innovative biological approach is PRP therapy for hand injuries, particularly effective in early-stage arthritis and soft tissue damage. PRP, or Platelet-Rich Plasma, is derived from a small sample of the patient’s own blood. It contains concentrated growth factors that stimulate tissue regeneration.

How PRP Therapy Works:

Blood is drawn and spun in a centrifuge to isolate platelet-rich plasma.

The PRP is injected into the affected hand joint or tendon.

Growth factors in PRP initiate healing, reduce inflammation, and promote tissue regeneration.

Applications:

Early-stage osteoarthritis

Ligament and tendon injuries

Post-surgical recovery aid

Combined with physical therapy

In cities like Hyderabad, PRP therapy for hand injuries is increasingly being used as a complementary or standalone hand joint pain treatment for patients seeking a faster return to daily activities without surgical downtime.

Non-Surgical Hand Pain Treatment in Hyderabad

For many arthritis sufferers, the idea of undergoing surgery is daunting. This is why non-surgical hand pain treatment in Hyderabad is becoming a preferred route for long-term relief.

Leading Non-Surgical Treatments Include:

Physical Therapy & Occupational Therapy Customized exercises to strengthen hand muscles, improve flexibility, and support joint function.

Bracing and Splinting Provides support, reduces strain on joints, and alleviates pain during repetitive hand movements.

Ultrasound & Laser Therapy Used to reduce inflammation and stimulate soft tissue healing.

Biologic Therapies Including both Stem cell therapy for hand pain and PRP therapy for hand injuries, offering natural healing and tissue regeneration.

Medications & Supplements Anti-inflammatory drugs, hyaluronic acid supplements, and topical analgesics are commonly used.

The growing number of clinics and specialty centers providing non-surgical hand pain treatment in Hyderabad reflects a broader shift toward patient-centric, low-risk therapies that aim to restore quality of life without hospitalization or extended recovery times.

How to Choose the Right Treatment

The ideal hand joint pain treatment depends on several factors:

Severity of arthritis (mild, moderate, or advanced)

Patient age and overall health

Response to previous treatments

Presence of ligament or tendon injuries

A qualified hand specialist or orthopedic doctor in Hyderabad can evaluate your condition and recommend the most suitable approach—whether that involves Stem cell therapy for hand pain, PRP therapy for hand injuries, or another non-surgical hand pain treatment in Hyderabad.

Clinical Outcomes and Patient Testimonials

Studies have shown that both stem cell therapy for hand pain and PRP therapy for hand injuries can lead to significant improvements in pain scores, joint function, and patient satisfaction.

In Hyderabad, several orthopedic clinics and regenerative medicine centers now offer tailored plans for arthritis patients. Many individuals report:

50% or more reduction in joint pain

Improved hand grip strength

Better range of motion

Enhanced day-to-day comfort

Patients especially appreciate that these treatments are outpatient-based, require minimal downtime, and avoid the risks associated with invasive surgeries.

Conclusion

If you're struggling with hand arthritis and are exploring your options, it's important to know that hand joint pain treatment has evolved significantly. Thanks to advancements in Stem cell therapy for hand pain and PRP therapy for hand injuries, patients now have access to safe, effective, and non-surgical hand pain treatment in Hyderabad.

Diesel Fire Protection Pumps: Giving Peace Of Mind When It Counts Most

Diesel pumps are mechanical drive motors that move fluids of all kinds and do so reliably and effectively across some industries. Their durability and ability to work in some of the worse conditions imaginable have made diesel pumps an essential requirement in agriculture and construction, mining, petrochemical, and emergency response.

What Is a Diesel Pump?

A diesel pump is essentially a pump that uses the power of a diesel engine to power the pump, or pumping machine itself (either a rotating impeller or a hydraulic displacement unit) which results in pressure differential to transfer liquids (for example, water, oil or chemicals) from one location to another location. Diesel pumps have a reputation for their longevity, efficiency, and fuel economy and can be used for either normal or heavy duty applications.

Important Features and Types

Versatility and Customization

Diesel pump pumps are utilized for the treatment of non-aggressive petrochemical and chemical fluids, and they can even be utilized in risky situations where fire or explosion is expected.

There are various kinds of diesel pumps that are specially designed for a specific application, as long as it is up to some standards of operation for business and industrial applications

Uses In Various Industries

Agriculture

Diesel pumps are used extensively in irrigation, pumping well water from rivers or reservoirs into fields without electricity.

Construction

They are critical to hydraulic power for hydraulic systems, mixing concrete, and dewatering excavations.

Mining

Diesel pumps transport fuel and water in mining operations, often used in remote or hostile environments where electricity is not available or is intermittent.

Oil and Gas

In drilling and refining, diesel pumps supply fluids and offer hydraulic fracturing water, valued for their durability and ruggedness in harsh conditions.

Fire Protection

INST Disciplined Engineer

Diesel fire pumps are essential standby systems that offer fire extinguishing capacity in case of power failure in industrial and commercial structures.

Selecting the Proper Diesel Pump

Proper diesel pump selection is based on many factors:

Operating Requirements: The use for which the pump has to be designed (e.g., fire extinction, fuel transport, water transfer) will determine the kind of pump. 

Flow Rate: The quantity of liquid to be moved should be compatible with the ability of the pump so that it does not become overloaded or underutilized.

Head Capacity: The pump must be capable of lifting fluids to the applied operating height, and low head centrifugal pumps and high head displacement pumps are appropriate. 

Conclusion

Diesel pumps are an industrial workhorse in the contemporary world, offering unprecedented flexibility, reliability, and efficiency for all fluid manipulation operations. Their autonomy from electric grids, ability to resist harsh weather conditions, and that they can be customized as per specific specifications make them a necessary investment for businesses that desire robust and efficient pumping systems. For irrigation purposes, for building construction, for mining operations, or for fighting fires in emergency situations, diesel pumps fuel development in all parts of the globe.
