Riccardo calafiori.

Car ride.

Summary: calafiori drives you back home although you dislike each other but you end up blowing him.

"Never trusting Giulia again," you mutter through clenched teeth, fingers squeezing your nearly-empty plastic cup like it personally wronged you.

Your eyes cut across the crowd to him. Riccardo Calafiori. Six feet of smug, sun-kissed arrogance, leaning against some half-crumbled stone wall like he owns the place. He’s half-laughing, half-whispering to two girls who look like they stepped straight out of an Instagram thirst trap—body glitter, mesh tops, and expressions that practically purred "take me for a spin."

Typical.

You watch him play it cool—head tilted, smile lazy, tattoos peeking from the sleeves of his t-shirt like an afterthought. The girls are eating it up. They don’t know him like you do. They don’t know that behind the jawline and the too-smooth charm is a guy who offers nothing more than a one-night ego boost and maybe a hangover.

And speaking of cars—that’s your problem.

You’re stranded. Somewhere outside of Rome, in the middle of a neon-lit rave that’s still pulsing at 4:30 a.m., all because your beloved cousin Giulia beggedyou to come. She swore it would be “legendary.” What she failed to mention was that she’d dip the second her ex showed up with those fake “we should talk” eyes and a very obvious agenda.

But before ghosting you, she tossed you a final favor—Riccardo will drive you home. Said it so casually too, like he was a damn Uber. Apparently, he “owes her one” because she once faked some blood test results to cover up the fact he’d been smoking weed before preseason training.

Classic Giulia.

So now, it’s past 4 a.m., your feet ache from dancing, your phone’s at 12%, and the only thing more annoying than this situation is him—because Riccardo Calafiori is still posted up like he’s on a magazine shoot, no intention of leaving, let alone remembering he’s your ride.

You sigh hard, toss the cup into a bin overflowing with glowsticks and crushed Red Bull cans, and start walking toward him.

The beat of the music throbs beneath your boots as you weave through the crowd. Each step forward is powered by caffeine, exhaustion, and pure annoyance. You feel your heart rate spike as you get closer, not from nerves—but from the sheer audacity this guy continues to breathe like he hasn’t left you waiting for hours.

When you reach him, one of the girls clocks you first. Her eyes narrow, sizing you up like you’re competition—which is laughable.

“Riccardo,” you snap, loud enough to cut through the music. “We’re leaving. Now.”

He doesn’t even look at you at first.

One of the girls giggles. The other smirks and mutters something to her friend in Italian, probably about your shoes, or the fact that your eyeliner is smudged from crying over how not fun this night turned out.

Riccardo finally turns to you, one eyebrow raised, like you’re the one interrupting.

“What?” he says flatly, voice a little hoarse from shouting over music all night. “Can’t you see I’m in the middle of something?”

Your mouth drops open for a second. Is he serious?

“I’ve been waiting for over an hour,” you spit. “Giulia said you’d take me home. Or did you forget the whole covering your ass with the fake drug testthing?”

His expression doesn’t change. That’s the worst part. He just looks at you with that bored, borderline amused smirk he’s so good at. The one that’s probably gotten him out of trouble his whole life.

“Yeah, well, I didn’t exactly promise a time,” he shrugs. “You’re a big girl, right? You can wait.”

You scoff, something sharp and bitter rising in your throat. The girl closest to him leans against his arm a little tighter, and her eyes trail over you with that condescending pout people save for someone they think is beneath them.

You flip him off.

No words. Just the middle finger, raised high and proud like a battle flag.

“Fine,” you snap. “I’ll find my own way back. Enjoy your groupies.”

And just like that, you spin on your heel, leaving him in the dust of your frustration and fading patience. You don’t even care if he watches you go.

-

Fuck calafiori

Fuck Giulia

You fling the empty plastic cup against the curb with enough force to hear it crack open like a broken promise. The neon haze and pounding bass of the rave bleed behind you as you stalk down the cracked asphalt, jacket collar turned up against the 5 a.m. chill. Every step is an anthem of fury—Giulia, Riccardo, the entire world can go to hell.

Half a mile out, you finally stop, heart hammering, lungs burning. The road is deserted, except for the distant glow of headlights. You glance at your phone—6 % battery, no bars. You bite back a curse and keep walking.

Suddenly, a low rumble rips through the quiet. A sleek black hatchback coasts up beside you, headlights slicing the darkness. The window slides down with a soft electric hiss.

Riccardo Calafiori leans one arm on the sill, eyes hooded, jaw set. He seems rather frustrated.

“Seriously? You’re walking?” His tone is equal parts amused and exasperated.

You don’t slow. You don’t even look at him. “Yeah,” you snap. “And I’d rather get mugged by hobos than sit in your throne of ego.”

He straightens. “Fine. Walk then. But don’t say I didn’t warn you—there are crazies out here.”

You flick your hair over your shoulder. “I’ll take my chances.”

He hesitates, then cuts the engine. “You’re doing this on purpose, aren’t you?”

You finally pause and glance over. “On purpose? Baby, I’m doing it because you promised Giulia, not me.”

His eyes narrow. “Don’t drag her into this.”

“Oh, I will,” you hiss. “Because she set me up to look like an idiot, and you’re too arrogant to own up to it.”

He exhales a harsh laugh. “I never said when I’d give you a ride. You assumed.”

Your chest tightens. “You owe her, you owe me, you owe someone. But it is always in your terms huh?”

“Y/N, get into the fucking car. NOW.” he almost shouts at you that fucking pig.

“Fuck you.” you hiss turning your back around determined to go back by your own- even if it meant almost getting assaulted.

“Okay then.” He studies you for a long beat, like measuring a challenge. Then he leans back, starts the ignition—and guns the engine just enough that you stumble backward.

“What the hell?!” you shout.

He flicks on his hazards, rolls the window down again. “All right, Ms. Stubborn—get in before someone actually does pick you up.”

You cross your arms. “Over my dead body.”

The car lurches forward and pulls in front of you, lights blinding. You skid to a stop, heart racing. The driver’s door swings open before you can think, and he steps out, coat flaring around him.

“We will do it your way then” he says quietly, voice low enough that you have to lean in to hear it. “I’m not asking anymore.”

You flare your nostrils. “Just back the hell off, Calafiori.”

He advances. His steps are deliberate. Each one cuts down the distance between you.

“Back off?” he repeats, voice rising on the last word. “I don’t think you understand how dangerous it is out here. What if someone worse than me sees you?”

Your lip curls. “You think I can’t handle myself? You think I need your “protection”?”

He stops right in front of you—so close you can see the faint stubble on his jaw and the tension in his throat. “I think you’re too proud to ask for help, even when you need it.”

A burst of anger rips through you. “I don’t need you. I need a ride home, which you promised.”

He steps forward and grips your upper arm. His skin is warm beneath your glove. You jerk away, but his hold tightens.

“Let me go!” you spit, breath catching.

He doesn’t budge. “Not until you calm down.”

“Calm down?” you laugh bitterly. “You don’t even know the half of it.”

He leans in, voice soft but lethal. “Try me.”

Your pulse spikes. You’re furious, but suddenly the road, the cold, the exhaustion all crash into you. You push at his chest; his hands slip around your waist like iron bands.

“Fine,” you rasp. “Fine. Put me in the car. Happy?”

In one swift motion, he lifts you—muscles coiling under his tee—spins you onto his hip, and carries you to the passenger door. You land with a thud, knocking the window aside.

“Get in. Now,” he growls.

You’re winded, angry, humiliated—and something in you snaps. You shove at his chest, but he’s immovable.

“Stop moving like a wild animal” he breathes, voice dangerously calm. “And don’t talk.”

He slams it shut behind you. You sit there, chest heaving, hands trembling on your lap as you stare out at the stretching road.

From the driver’s side, he mutters, “Buckle up,” and the engine turns over. The headlights carve through the night, but you remain frozen—half-expecting him to change his mind.

The car is dead silent, save for the dull hum of the tires kissing the harsh road. You sit there, arms crossed, still fuming from earlier. The seatbelt presses against your chest like a restraint—maybe it is. You didn’t want to be here. Not in this car. Not with him.

Neither of you speaks.

So, to break the silence—or maybe just to soothe your own rising irritation—you reach for the console and flip the music on, scrolling through the radio until you land on something soft. A slow, dreamy melody floods the car, something melancholic and delicate. The kind of song you’d hum under your breath when no one’s listening.

You settle back, gaze fixed on the dark stretch of road ahead, trying to forget the fact that he’s the one driving you home.

But it doesn’t last.

Within seconds, Riccardo reaches over and taps the screen with a sharp flick of his fingers. Your song is gone—replaced by a loud, thumping drill beat that slams through the speakers with zero mercy.

You blink at the dashboard, stunned.

“Seriously?” you mutter, voice cold.

He doesn’t look at you. One hand on the wheel, the other resting lazily on the gearshift. “Don’t play that girly shit in my car.”

You laugh under your breath, not the amused kind. “You’re such a child.”

“And you’re predictable.” He shrugs. “Didn’t even take you for the soft, sad playlist type. That’s rich.”

You turn to face the window, jaw clenched so tight it aches. “Just know I don’t like you.”

There’s a beat of silence.

Then he laughs. That short, smug, throaty laugh that somehow makes everything worse.

“Same here, actually.”

You glare at him from the passenger seat, your voice sharp and venom-laced. “Then why the hell did you even agree to give me a ride? To ruin your fun with your little groupies? Maybe if I hadn’t shown up, you’d be getting your dick sucked for the fourth time today.”

Riccardo lets out a low, bitter laugh, his fingers tightening on the wheel. “Exactly. But no—you had to come storming over like a goddamn hurricane and kill the vibe. Congrats.”

You twist toward him in your seat, heat rising in your face. “Oh, I killed it? Poor baby. Must be hard keeping your dick wet for 24 hours straight.”

He glances at you sideways, eyes dark with irritation. “Don’t blame me because no one’s lining up to suck yours.”

You blink. Once. Then smile—sweet, cruel. “Fine. Pull over and I’ll do it myself.”

The car jerks slightly as his foot stutters on the gas.

He turns to you like he didn’t hear right. “What?”

“You heard me,” you bite, voice steady and pissed. “If you’re that desperate, I’ll suck your goddamn dick. Would that shut you up for five fucking seconds?”

His brows furrow, expression flickering between disbelief and something hotter. “You’re insane.”

“And you’re pathetic,” you fire back. “Whining about a blowjob you didn’t even get like some high school jock who peaked too early.”

He scoffs, jaw tight. “You think I wanted to pick you up? I was doing Giulia a favor. If I’d known I’d be stuck with you, I would’ve left you in the goddamn woods.”

“Trust me,” you snap, “I wish you had. Being around you is like breathing in secondhand ego.”

“Then get out, you demon” he growls, pulling the car toward the side of the road.

You unbuckle instantly, hand on the door. “Gladly.”

But you pause, your hand resting there, both of you breathing hard, neither moving.

He looks at you. Tense. Challenged.

“I dare you,” he mutters.

You don’t move.

Neither does he.

And just like that, the air between you is fire—burning with rage, heat, and that stupid, unspoken desire that neither of you will admit out loud. Because it had always been that way, since you were teens. Always arguing and fighting over the verge, never crossing any line to something more.

But you didn’t wanna lose and go walk outside in the crisp cold yet you didn’t want to shut the hell up and continue to a dull drive.

Your hand lingers on the door handle, but something stops you from pulling it open. Maybe it's the sick thrill of pushing his buttons, maybe it's the sheer spite of showing him you're not afraid of his games.

Demon? oh now he will see.

Whatever it is, your eyes never leave his—until you decide to make good on your offer. Slowly, deliberately, you lean over the center console and unbutton your top. The fabric whispers down your shoulders and you feel his gaze on you, hot and hungry.

"Fine," you spit out. "You want a show? I'll give you one."

The car is a cage of tension now, the music a distant throb in your ears. You lean back in your seat, peeling the material away from your skin like you're shedding a second, irritating layer of yourself.

Your breasts spill out, nipples tight in the cold night air, and his eyes dart to them like a magnet. The smugness on his face wavers, but only for a moment. He's not expecting this. No one ever does.

You lean over and unbuckle your seatbelt with a vicious tug. The clasp snaps against the door and you slide closer to him, your bare chest brushing his arm.

His eyes are glued to your breasts, his breath coming faster, was he that dumb? or all men were when they see titties?. You can see the pulse in his neck quicken and a hint of color stain his cheeks, could it be the same for his cock? You smirk, knowing you've got him right where you want him—off balance, off guard.

"You want a blowjob? missed it so much you act like a woman in her period?" You lean in, your voice a seductive hiss. "Then sit back and watch the fucking master at work, because those tasteless whores can’t do it like me“

You don't wait for his response. You unbuckle his belt with the ease of practice, your hands moving with a confidence that makes his cockiness falter. He watches you with a mix of shock and excitement, his mouth slightly open.

“Didn’t knew you were like that y/n, not so uptight.”

You grab the waistband of his pants and yank them down, exposing his erection. It's thick and proud, jutting up like it's been waiting for this moment all night. You laugh again, that cold, empty laugh. "So, this is what all the fuss is about."

You wrap your hand around him, feeling the heat and the hardness, and start to stroke. His eyes snap to yours, a question in them—are you serious? You are.

So serious that your heart is racing and your mouth is watering. You lean in and kiss the tip, tasting the salt and the promise of power. He gasps, his hand flying to the back of your head to pull you closer. But you resist, keeping your mouth just out of reach.

"What the hell are you—" he starts to protest, but you cut him off.

"I'll suck you off," you murmur against his skin. "But on my terms." you never give something so easily and not to an asshole like Richy.

His hand tightens, his breath hitching as you take him in your mouth. It's a rough, nasty kiss—the kind you'd give to someone you hate. And maybe that's what makes it so hot. You can feel his shock, his excitement, his utter disbelief as you start to suck him. It's a battle of wills, and you're determined to win.

You're not some eager little groupie eager to please. You're the devil he talked about, and you're going to wipe that smug smile off his face. You suck harder, faster, your teeth grazing just enough to make him wince. He tries to push you down further, to control the pace, but you won't let him. You're the one in charge here, and he's just the tool for your spiteful satisfaction.

Your hand is still wrapped around the base of his cock, pumping in time with your mouth. The car is still idling, the engine humming like it's part of the background music to this twisted little show you are putting on.

His fingers dig into your hair, trying to guide you, but you ignore them, simply flinching and gently push them away. This is your dance, and you lead. You can feel him getting closer, his hips bucking slightly, his breath coming in shallow pants.

And that's when you stop. Just like that. You pull back and look up at him with a wicked smile. "Not so fast," you say, licking your lips. "I'm not done with you yet."

The look on his face is priceless—part anger, part arousal, all confusion. But you don't care. You lean back in, taking him deep again, and this time you don't hold back. Your teeth graze his shaft, a little more insistent than before, a little more like you mean it.

You can feel the muscles in your jaw tensing, your throat opening for him, and it's not about giving him pleasure anymore. It's about showing him you're not a toy to be played with, not a mouth to be used and discarded.

You suck him like you're trying to wring every ounce of satisfaction out of him, like you're taking back every shitty thing he's ever said to you. Your hand moves in a blur, stroking in time with your mouth, and you can feel the vibration of the engine under your palm, matching the rhythm of his hips.

“S-shit you are such a slut.” Riccardo let’s out a breathy moan.

He's getting into it now, his grip on your hair tightening, his breath coming in ragged, desperate gasps. But you keep that smug little smirk on your face, looking up at him through your lashes every few seconds just to make sure he sees it.

You're so focused on the fight in your mouth that you almost miss the moment he starts to lose control. His hand clenches, his body jerks, and he lets out a strangled groan. You keep going, your mouth a perfect O around him, your tongue flicking against his slit.

You can taste the pre-cum, and it's bitter, like victory. You're going to make him come like this, in the car on the side of the road, because you're in charge now. And when he does, you're going to swallow every drop, just to prove a point.

But as you feel him start to pulse, something shifts. The power you felt just moments ago is slipping away, replaced by a burning need to feel him come apart in your mouth. You suck harder, faster, your hand a blur of motion. You're so close to winning, so close to making him admit that you're more than just a girl in a sad playlist.

And when he finally does, when he bucks into your mouth and comes with a strangled shout, you do swallow—not for spite, but because it feels like the only way to keep that power, to keep this moment in your grasp.

You pull away, wiping your mouth with the back of your hand. Your heart is racing, your chest heaving. You're both panting, staring at each other in the dim light of the car. For a second, there's nothing but silence—no music, no engines, no night sounds. Just the two of you, breathing in the aftermath of something that was never just about a blowjob.

He sits there, his pants still around his ankles, his cock slowly going soft. His eyes are wide, his mouth hanging open a little. "What the fuck was that? You sure you are y/n and not posessed by a demon?" he manages to get out, his voice hoarse.

You shrug, your own voice sounding just as rough. "What it always is with you, Riccardo. Just a little bit of drama." You lean back in your seat, feeling a strange mix of satisfaction and disgust. "Now drive me home.“

The Life of The Prophet Muhammad(pbuh): The Assignment of the Duty of the Prophethood and First Muslims

They were all a test

The torture, persecution, insults, difficulties, and obstacles that the first Muslims were afflicted with were also tests sent by Allah. For example, it did not just end by saying, “I have testified to faith.” The amount of loyalty, sincerity, and patience in faith had to be measured as well.

There had to be an excessive level of difficulty, persecution, and torture so that those who truly carried the desire of belief in their hearts would testify without paying attention to such inconveniences, whereas those who did not sincerely carry this desire would be separated from the true believers.

As a matter of fact, the following Quranic verse indicates this issue:

“We did test those before them, and Allah will certainly know those who are true from those who are false."

Thus, the most important measure of one’s sincerity in faith is not bowing before the difficulties, torture, cruelty, and persecution that he/she may face.

Such unbearable persecution, torture, cruelty, and insults could not break the courage of those genuine Muslims who submitted to Allah and His Messenger (PBUH) in the truest sense. The polytheists could not hinder them from standing their ground in the circle of guidance or prevent others from running to that circle. The torture, persecution, and insults were like the wood that caused the fire of Islam to burn more strongly and to shine more brightly. As the polytheists continued with their acts of torture and persecution, the Islamic cause was developing at a greater speed, being spread, and continuing to reign with its light over hearts.

Undoubtedly, tyranny and violence have never been able to continuously overcome and suppress the truth in any era, nor have they been able to muffle or enslave it. On the contrary, the truth has been able to defeat tyranny, cruelty, and darkness and has annihilated them on many occasions.

The incomparable courage, immense patience, and magnificent amount of fortitude the Muslims showed against the persecution and cruelty during the Era of Bliss are full of lessons for today’s Muslims to learn from and they possess such a high level of sublimity that can bring those who truly possess prudence and a sense of justice to tears.

Even Leone Kaitano, an Italian writer, historian, and a staunch enemy of Islam, could not contain himself from making this confession:

“What is bewildering is that there was not even a single apostate among them!”

Actually, what is bewildering is that a writer who makes this type of confession can continue being hostile towards Islam instead of submitting his heart and pen in the way of Islam and continues to close his eyes amid broad daylight so as not to see the sun.

How to choose you Bridal Hair & Makeup Artist ?

How to choose the perfect Hair & Makeup Artist:

Picking the right hair and makeup artist isn’t just about finding someone who can nail a smokey eye or craft a flawless updo. It’s about finding the one—your beauty soulmate, your backstage wizard , the creative genius who gets your vibe and helps you feel unstoppable. Let’s break it down.

1. Experience is key—This isn’t the time for beginners

Would you let a brand-new guitarist headline your show? Probably not. The same goes for your hair and makeup artist. Experience isn’t just a bonus—it’s essential, especially for major events like weddings or photoshoots where every detail matters.

Check their portfolio: does their work scream polished pro? An experienced artist will know how to handle every skin tone, hair type, and even those last-minute “can we fix this?” moments with ease.

2. Find an artist who matches your energy

Your style is unique, and your artist should reflect that. Whether you’re channeling old-Hollywood glam, boho-chic vibes, or full-on rock goddess energy, their work should feel like a natural extension of your vision.

Scroll through their Instagram or website. If you find yourself saying, That’s me! when you see their work, you’re on the right track. If their portfolio feels more glitter and glam when you are more grungy and edgy then don’t settle—keep looking for someone who aligns with your aesthetic.

3. Research Like a Pro

Think of hiring your artist like signing a contract—you wouldn’t commit without checking the details first. Dive into their social media, website, and reviews to get a sense of their skills and personality.

Red flags to watch for? Inconsistent work, overly edited photos, or portfolios that feel too one-note. Don’t hesitate to ask questions, either. How do they prep skin? Can they handle your curly hair or sensitive skin? The more you know, the better your choice will be.

4. Reviews Don’t Lie

Online reviews are like behind-the-scenes gossip—sometimes exaggerated, but often incredibly revealing. Look for patterns in what people say. Are clients raving about their professionalism, creativity, or calming energy?

Pro tip: Check out real-life photos tagged by clients. A polished portfolio is great, but seeing their work in action can be even more telling.

5. Align on Values

Your artist should get you—not just your look, but your priorities. If cruelty-free or vegan products matter to you, make sure they use them. Love supporting indie artists or local talent? Seek them out.

This is more than just looking good; it’s about feeling good too. An artist who shares your values will help you look amazing with a side of peace of mind.

6. Vibe Check: The Ultimate Test

The consultation is where it all clicks—or doesn’t. Pay attention to how they listen and respond. Are they genuinely excited about your ideas, or do they try to push their own agenda? The right artist will feel like a collaborator, not just a vendor.

Bonus points if they can chat about your favourite eyeliner, band, their go-to frizz tips, and the perfect playlist for your event in the same breath, then you know you are onto a winner.

Final Thoughts: Bring Your Vision to Life

Choosing a hair and makeup artist isn’t just another task—it’s a chance to find someone who makes you feel like a total rock star. Look for a pro with the skills, personality, and vibe to match your style.

When you find the one, you’ll know. Your hair will be flawless, your makeup will be fire, and you’ll step into the spotlight looking and feeling like the headliner you were born to be.

The six-minute walk test is done to check your heart and lung function. Know how to prepare for the test and how it can help you.If you don’t have a habit of walking every morning or evening, walking for six minutes in one go can feel like a really long time. But if you have a lung or heart problem, you would like to know how severe it is. This is where the six-minute walk test comes in. It is a common test that measures how much you can walk in six minutes while sharing with a medical expert how you feel. You may feel short of breath or find it hard to walk for six minutes if your heart and lungs are not strong. Apart from assessing people with heart and lung conditions, the six-minute walk test can also be used to measure exercise capacity in elderly people with other health conditions such as rheumatic conditions like osteoarthritis.What is the six-minute walk test?The six-minute walk test is a simple measure taken during clinical and rehabilitation settings for the evaluation of a person’s functional exercise capacity. The test is simple, safe and does not require any sophisticated equipment. It assesses the submaximal level of a person’s functional capacity while walking on a flat and hard surface during a six-minute walk, as per research published in Therapeutic Advances In Cardiovascular Disease in 2019.The six-minute walk test is safe and simple. Image courtesy: Adobe Stock“It is normally used in people with chronic obstructive pulmonary disease, heart failure, and pulmonary hypertension,” says physiotherapist and fitness expert Dr Aijaz Ashai. Arthritis, spinal cord injury, and muscle disorders are also some of the conditions where this test can be used.Purpose of the six-minute walk testThe purpose of the six-minute walk test is to test the cardiovascular and pulmonary endurance of a person. “It can follow along the changes of exercise capacity over time, especially for people with chronic conditions,” says the expert. Since this test measures cardiovascular and pulmonary function, significant problems can be detected early, and so, intervention may be instituted.You may also like“It also encourages a person to get into some sort of physical activity, which is an essential behavioural aspect of maintenance for health,” says the expert. It can also be applied in the rehabilitation area to monitor progress when recovered, following surgery or handling chronic diseases.How is the six-minute walk test done?Here’s the procedure of this test: A brief explanation is given to participants about the test and what they are expected to do. They walk back and forth on a predetermined distance, typically 30 meters, for six minutes. The total distance covered in meters is recorded, and any additional observations, such as heart rate, perceived exertion, and oxygen saturation, may be noted. These distances are compared with normative values based on age, gender, and health status to assess an individual’s functional capacity.Here are a few points to keep in mind before taking the six-minute walk test: Wear comfortable clothes and shoes. Stay hydrated before the test, but avoid excessive fluid intake. Perform a light warm-up exercise before the test. Heavy meals, caffeine and stimulants should be avoided before the test, as they can affect your heart rate and perceived exertion. You should confirm your medicine intake with your doctor before the test.Warm up before taking the six-minute walk test. Image courtesy: Adobe Stock.What is a good six-minute walk test score?Most adults are declared healthy if they attain a score of 400 to 700 metres in six minutes, as per research published in the Respiratory Medicine in 2006. “The test score for elderly people should be about 300 to 600 metres. People with chronic conditions may have lower scores, but anything less than 300 metres may mean there is a significant functional impairment,” says Dr Ashai.Being able to walk a greater distance suggests better cardiovascular fitness, endurance, and functional capacity.

It may indicate that a person is better able to engage in daily activities without excessive fatigue whereas distances significantly below the average for one’s demographic may signal reduced functional capacity or limitations in physical health. This can prompt further evaluation and interventions, such as rehabilitation or lifestyle changes.Who should not take the six-minute walk test?People with uncontrolled hypertension and a resting heart rate more than 120 beats per minute should avoid taking this test, as per research published in StatPearls in 2023. Others who should not take the six-minute walk test are people: Who may have undergone a recent surgery Have severe joint issues Have high risk of falling Have a history of an acute coronary syndrome, which is a range of health conditions associated with sudden, reduced flow of blood to the heart Have acute respiratory failureSummaryThe six-minute walk test is self-paced, and can be useful in knowing how well your heart and lungs are functioning. It serves as an indicator of cardiovascular and pulmonary function, allowing for early intervention if necessary. With frequent follow-up and assessment, health conditions can become better managed and improve the quality of life. All you have to do is walk as far as you can within six minutes along a flat and straight course.

S23 Ultra: They Copied Apple?The Samsung Galaxy S23 Ultra is arguably one of the best smartphones on the market, retailing at $1199. Despite its impressive features, it has earned a repairability score of only 4 out of 10 from iFixit. In this story, we will unbox the device, explore its interior, and verify its challenging repairability.Unboxing the Galaxy S23 UltraUpon opening the packaging, one notices the absence of plastic, replaced by eco-friendly materials.

Vacuum Chamber Package Testing Methods

Vacuum chamber package testing is a non-destructive method of inspecting packages for leaks and defects in a reliable and deterministic way. Holes and cracks in trays or cups sealed with porous barrier lidding materials can be detected, along with channel defects in continuous and dot matrix adhesive seal systems.

From smaller benchtop chambers to larger aerospace sizes, there are vacuum testing methods for all industries. Let’s explore some of the most common and valuable tests.

Bubble Leak Test

A relatively inexpensive method of determining package leaks, the bubble test is a simple way to check for a breach in a sterile barrier. Essentially, the product is submerged in a water chamber and a vacuum device is engaged to cause the package to expand. Bubbles that rise from the container indicate a breach in the sterile barrier.

This method is also known as bubble emission testing and can be used on food or product packaging that contains headspace gas. A test report is generated that includes important information such as the date and operator’s name, the package type and any identification numbers, the defect size used to establish the test sensitivity, the use of blocking agents and the test pressure.

This test is a destructive test and just like dye penetration, it will cause some damage to the packaging and product being tested. This method can be used on flexible containers with or without a lid.

Burst Strength Test

Burst strength testing is used to inspect the capacity of a package to resist internal pressure. The test involves creating a consistent internal pressure in the package and inspecting it for material failure. The test can be conducted in both restrained and unrestrained modes. Restraint limits the expansion of the test package, which allows it to be distinguished from packages that have weak seals. Using this method, channel defects in rigid and flexible trays and cups sealed with porous barrier lidding materials and severe seal bonding defects in both continuous adhesive and dot matrix adhesives can be detected.

This non-destructive test can detect gross leaks as well as test the seal strength of the packaging under differential pressure conditions that may occur during transportation and storage. It also enables manufacturers to recover packages that fail the test and return them to production. The primary equipment required is a water-resistant vacuum chamber and an immersion fluid. The fluid can be water, denatured alcohol or mineral oil, but it must not degrade the test samples.

Pressure Change Test

One of the deterministic leak test methods referenced in USP 1207 guidance, this test method utilizes a hermetically sealed chamber and measures the difference in pressure between the package and the testing system. In this test, the package must be able to withstand differential pressures similar to those encountered during air transportation to prevent product loss or contamination.

This nondestructive test fills the test vessel to its target pressure, then cuts off the air source and monitors the change in test chamber pressure for a set period of time. A change in test chamber pressure greater than a predetermined set point indicates the presence of a leak.

This method is optimal for work that does not have a pressurization port, such as trays and cups. PTI’s VeriPac inspection instruments utilize this leak detection technology to evaluate the performance of a variety of filled and sealed rigid and flexible packages. Unlike bubble tests, this method is capable of detecting leaks in the low micron range.

Temperature Change Test

The Temperature Change Test, or immersion leak test is a nondestructive method of inspecting packaging for defects. It uses clear vacuum chambers which submerge the test package and allows air to flow through any existing leaks causing bubbles to appear, indicating that a leak exists.

The test can be used to inspect rigid and flexible trays and cups sealed with porous barrier lidding material (headspace gas leakage). The test can also detect holes or cracks in the wall of the tray/cup as well as channel defects in the seal area caused by dot matrix adhesive bonding systems.

The test is typically a Weibull failure analysis based test with a time limit set. This means that the test is stopped as soon as a specified failure criterion is met, but it may be performed with more than one test sample to determine a trend for a given product. It’s essential that the rate of temperature change in the test be high enough to allow for a quick transition between temperatures to shorten the total test time.
