![]() ![]() ![]() And the church neither commonly nor clearly communicates what should be a cornerstone of any Christian sex talk: Because few and far between are the folks who, like Pope John Paul II, remind the world that love is “the authentic commitment of the free will of one person, resulting from the truth about another person.” We are hard pressed to hear sermons or read books that say marriage is designed to result, in part, in the destruction of self absorption. I know this because of how rare it is for people in the church to talk about love like it’s any deeper than sentiment, attraction or infatuation. In the realms of love, marriage and sex, the church has dropped the ball. It is perpetuating a problem that underlies it: And when the body of Christ consumes erotic media and praises it for what it does for sex and sexuality in Christian marriages, it really isn’t alleviating the problem. A woman has never been sexually frustrated because what she really needs is to be part of a culture in which women and men are objectified the same amount. The reason a marriage is sexless or women are sexually frustrated is complex, but a marriage has never been sexless because it hasn’t had enough exposure to erotic media. But since when does what a person uses to meet a need necessarily equate to what a person actually needs? I understand why, when erotic media is a catalyst for important sex conversations, Christians defend it. So I understand why, when erotic media inspires sex in a marriage, Christians use it. In its wake, I am left with a realization: That there are followers of Christ among the women who latch on to erotic media is, indeed, indicative of the existence of a need. This week, the fanfare that sparked the fight for erotic media has faded. That as such, erotic media can be a powerful weapon in the war against sexual oppression. That it acknowledges the existence of desire where the church often has denied it. ![]() That erotic media designed for women validates female sexuality in a world that rarely does. One said if erotic media objectifies people, it’s only a problem when women and men are unequally objectified. What erotic media does for sexless marriages and sexually frustrated women is important, some said. It is good, one woman wrote in a blog comment, because “giggling over guys in thongs gets women to talk about what they like and don’t” in sex.

The shunt has 2 large bolts on top, these are for the negative wires.ġ) You need to find a place to mount the shunt. You can see that someone did try to put all the larger cables on the bottom battery, so its close to perfect positioning. If there were enough space, or fewer positive cables, then you'd want all the positive cables going to the second battery, with just a single positive cable between it and the first battery - this way the overall distance travelled from any device/charger would be the same, either 12" longer on the outgoing positive side or 12" longer on the incoming negative side. Technically that 12" cable means the first battery has slightly less resistance involved in power coming/going, so it will be used slightly more, and wear slightly more/faster than the second battery. If they were in series, then one battery's negative would connect to the other battery's positive.Īll the negative wires coming in to the top battery are also connected to the bottom battery's negative by the short black cable. ![]() You can tell this because the black cable goes between the negative poles. This means they output 12 volts, and the sum of the amps of the two of them. G) Your batteries are hooked up in parallel. Generally speaking, try to only work with negative or positive cables at any given time. Otherwise wrap some electrical tape around the lug. If you have little rubber caps or something, that'd be even better. This way if the cable gets pushed out of the way while I'm working, I don't accidently push it into something like a cable/battery pole of the opposite polarity and cause a short (as in Boom, sparks, bad things!). So long as you have no metal and are not working in wet weather, you should be fine so long as you don't let a wrench or screw driver or something lay across both positive and negative cables at the same time.į) When removing a lug from its position on the battery, unless I'm moving it to somewhere else right then, I always immediately wrap a little plastic baggy or two around it (I have small ones that are just a few inches square). It happened to a service tech while I was in a RV repair center once, and he got a nasty burn around his finger because of his wedding band, which he'd forgotten to take off. This step is important because if you have metal on your hand/fingers and accidently touch a positive cable to it, you can get shocked and burned. This is needed for working on the battery cables, as if it is on and you remove the negative wires (ground), you can burn out your LVD.ī) Engine off, so no charging coming from there.Ĭ) Shore power NOT plugged in, so no charging from there.ĭ) If you want to be super-safe, you can throw a blanket over the solar panel, so no power charging from it.Į) Take off ALL jewelry from both hands.

I prefer to figure this out myself (with your help of course) versus seeking help somewhere. I'm assuming before I start disconnecting anything that I need to obviously be off shore power, in "store" mode - anything else need to be shut down/disconnected to preserve my life! Which cable is going to the Start Battery, or none? and does that even matter? Should the start battery cable also go through the shunt? So many questions.Īnyway, I'm confused and need a little guidance if there is any to offer here. How do I know what's what? I also expected to see a different config of the two batteries cabled in series, but I don't think they are - it seems like they are independent of each other, or at least have the loads split between to two? I have no idea. Shunt instructions are pretty basic - Attach all the drawing loads to the Negative side of the shunt, run the positive lead to the positive on the battery and done! There's a video on the Victron Site and YouTube, but. So, total novice on this stuff, but for whatever reason I didn't expect to see this - all the cables and various connection points. ![]() ![]() ![]() ![]() Somewhere in space, Star Sapphire of the Star Sapphires, Sinestro of the Sinestro Corps, Atrocitus of the Red Lantern Corps, Saint Walker of the Blue Lantern Corps, Larfleeze of the Orange Lanterns, and Indigo-1 of the Indigo Tribe are summoned. while unlocking new characters and other collectibles.

He wrote about homosexuality describing it as something that was completely natural, but Vidal’s viewpoint was everyone is bisexual. He’s not remembered as being an advocate for the LGBTIQA+ communities, but his creative output and public comments certainly had an effect on challenging homophobic attitudes. Gore Vidal was a prolific author and commentatorĪuthor Gore Vidal was born on this day in 1925.Īuthor Gore Vidal disliked the word gay to describe homosexuals, friends have recounted he always used the descriptor ‘fags’. She is remembered as one of the best rock singers of all time. ![]() Over the years a number of live recordings have also been released. Joplin left behind four studio albums, two with Big Brother and the Holding Company, and two solo records. In later years Nirvana frontman Kurt Cobain, artist Jean Michel Basquiat and singer Amy Winehouse would also be 27 years old at the time of their passing. ![]() The following year The Doors’ Jim Morrison would overdose at the same age, and the Rolling Stones guitarist Brian Jones would also be added to the list. The collective deaths are often referred to as the 27-club, an informal list of actors, artists and musicians who have died from overdoses. All three were 27 years old at the time of their passing. Just sixteen days after Joplin’s death, guitarist Jimi Hendrix also passed away. Joplin’s death at 27 shocked music fans and followed just a month after the death of Canned Heat singer Alan Wilson. In 1970 the posthumous album Pearl became the biggest of her career and included her take on Me and Bobby McGee, a song written by Kris Kristofferson and Fred Foster, that had first been performed by Roger Miller. The coroner later ruled her death was a heroin overdose and that alcohol was also a factor, describing in her passing as an accidental death. Joplin was found dead on the floor of her hotel room at the Landmark Motel in Los Angeles on this day in 1970, her body discovered by her road manager and close friend John Byrne Clarke. The singer continued to tour and spend time in the studio working on her next album, but she was increasingly reliant on alcohol and drugs. By this stage the singer’s drinking and drug taking was growing again and at times it seriously affected her ability to perform. Joplin had gone solo by the time she appeared at the legendary Woodstock Music Festival in 1969. In 1968 the band covered the song Piece of My Heart, which was originally recorded the previous year by Erma Franklin, the older sister of soul singer Aretha Franklin. Soon the band was being billed with Joplin’s name out the front. The band toured the west coast of America and began building up a loyal fanbase and the following year released their debut album. Friends banded together to buy her a bus fare home to Texas where with the help of her family she returned to good health.īy 1966 she had returned to San Francisco where she joined psychedelic rock band Big Brother and the Holding Company. ![]() She began recording music, but also struggled with addiction to methamphetamine, heroin and psychogenic substances. In 1962 she dropped out of college and hitchhiked to San Francisco. She began performing blues numbers with school friends, and when she went to college, she joined a folk trio. In the years since her passing, it’s also been recognised that Joplin was bisexual and had many relationships with both men and women.īorn in Texas in 1943, Joplin suffered bullying during her school years and found solace in the music of blues greats including Bessie Smith, Ma Rainey, and Lead Belly.

No part of their body should touch the bar as they cross it.Īdditionally, no part of their legs should touch the ground other than their feet, and their head shouldn’t move from side to side. ![]() To pass underneath the bar, the player must arch backward. However, in informal settings like house parties, the horizontal bar can be held in the air by two people on either end instead. The centerpiece of the game is a horizontal bar held aloft at the chest level of the player with two vertical bars. We have already briefly explained the rules of the dance earlier. Sources pointed to the Limbo dance’s striking similarity with the legba or legua game in Africa, which is a kind of funeral game with the same basic rules. You’re basically moving from life to death when you pass across the bar. Much like the bar that gets lower the more passes you make through it.Īnother interesting origin story we have heard is that the Limbo dance signifies limbo – the land in between life and death. But no matter how much they try, they still don’t seem to fit, so they get lower and lower. That means enslaved people back then had to contort their bodies every which way and arch their backs to fit. They were designed more like cargo holds than passenger cabins, so people were packed together like sardines in a can. It says that the Limbo dance is meant to symbolize enslaved people being taken into the galleys of slave ships. One of the most popular interpretations is quite dark. But there have been many hypotheses over the years about the Limbo dance history. Little is known about the actual origin of the dance. However, it was not until the 1950s that the dance became popular. Most sources agree that what is now known as the Limbo dance appeared in Trinidad around the 1800s. ![]() So, Trinidad and Barbados are common answers to the question “Where did the limbo dance originate from?” Specifically, it’s a derivative of the word “limber”. The word “limbo” itself dates back to the 1950s.Īccording to the Merriam-Webster dictionary, the root of the word “limbo” can be traced back to the local variation of English spoken by the people from Trinidad and Barbados. Most people will be surprised to learn that the Limbo dance is very old. Besides being extremely fun to play and hilarious to watch, the fun doubles when you mix it with alcohol and drunk people! Limbo Dance Origin You probably already see why it’s such a popular party game. The game ends when the player can’t lean back far enough anymore to clear the bar. The bar is lowered slightly, and the player has to do it again and again, with the bar getting lower and lower. When they emerge on the other side, they have “won” a round. It’s going to be set at a certain height (usually at chest level, around a meter or so off the ground).Īnyone who wants to “play” must lean backward and try to fit their body underneath this bar. So long that it’s straight, rigid, and laid horizontal, it’s fine. The dance involves a horizontal bar, which can be anything: a long wooden pole, a broom handle, a curtain rod … you name it. You’ll know immediately when someone or a party is hosting a Limbo dance session. And we do mean it: there’s no other dance like it out there. ![]() ![]() All are acceptable, as long as you like it-just be sure to think about whether the bathroom color scheme is something you are willing to either live with or modify in the event that your taste changes in the future. This may result in bright green cabinets, pink tile or dark walls that coordinate perfectly with your vinyl flooring. So, instead of going for the color you think should go in a bathroom, select colors that you love. Who decided that a bathroom had to be neutral in color? The truth is, the bathroom is just as apt to benefit from a color scheme change as any other room in your house. Naturally, steam showers aren’t going to be easy on everyone’s budget-but if you have the resources, this is a bathroom remodeling project that you most certainly will not regret. Steam showers essentially re-create the spa experience at home, and some even incorporate aromatherapy, Wi-Fi, lighting and other high-tech features. One way to do this, Lovato says, is by replacing your regular shower with a steam shower. These days, everyone is looking for ways to incorporate a little self-care into the daily routine. ![]() ![]() Some higher-end medicine cabinets even incorporate USB ports so you can keep all those electric toothbrushes hidden behind closed doors. And today’s medicine cabinets are a far cry from the medicine cabinets of yore, she says, explaining that you can now find medicine cabinets that offer just as much in terms of design appeal as they do in space to store your ibuprofen. Wait, a medicine cabinet? Aren’t they a little on the antiquated side? Believe it or not, medicine cabinets are making a comeback, says Lovato. However, you don’t have to stop there-today’s toilet manufacturers are incorporating heated seats, automatic flushing, self-cleaning and smart technology into their designs. One of the obvious choices, Lovato says, is to add a bidet (something that feels almost like a requirement after the great toilet paper shortage of 2020). While a basic toilet gets the job done, a bathroom remodel is the perfect opportunity to switch the basic out for something a little more luxurious. What exactly is an undermount sink? As the name implies, it is one that you install from beneath the countertop (overmounts, on the other hand, are dropped in from above).Īvailable in a range of colors, styles and price points, adding an undermount sink to your bathroom is an upgrade won’t regret-and one that will likely leave you wondering why you waited so long to make the switch. ![]() Undermount sinks are known for their sleek design, but one of their best features is the fact that they are so much easier to clean than their traditional overmount counterparts, Lovato says. The one caveat? Freestanding tubs can be hard to get in and out of for some people, so keep that in mind before you commit. Instead, she recommends freestanding bathtubs, which are elegant, timeless, and easier to reface. “Built-in deck bathtubs used to be the thing, but now they look dated and take up a lot of space,” Ariana Lovato, owner of Honeycomb Home Design in Shell Beach, California, told Forbes Advisor. 9 Bathroom Remodel Ideas That Will Transform Your Space While we work hard to provide accurate and up to date information that we think you will find relevant, Forbes Home does not and cannot guarantee that any information provided is complete and makes no representations or warranties in connection thereto, nor to the accuracy or applicability thereof.

The tetraborate anion reacts with water to produce boric acid and two hydroxide anions. In the first step, sodium tetraborate dissociates into sodium cations and tetraborate anions. The step-wise mechanism in Figure 2 shows how sodium tetraborate in water produces boric acid. These chemical intermediates help explain the step-wise mechanism for the formation of the borax cross-link detailed in Figure 2.) Figure 1: Borax cross-link within polyvinyl alcoholĬopyright © 2011 Cherelle Bishop, Colorado State University Typically, chemical intermediates are quite reactive. Figure 1 shows how the sodium tetraborate, the active ingredient in borax, facilitates the formation of tetrahydroxy borate through a boric acid intermediate (Note: A chemical intermediate is a reaction product of one or more steps in a step-wise reaction that is not a final product in the chemical reaction. ![]() Students make their different formulations of poly(vinyl alcohol) by adding different amounts of sodium tetraborate (saturated borax solution). Then they design new versions of the putty that satisfies one of two different requirement options: very stretchy or rigid enough to bounce well. Students synthesize polymeric materials and create two different formulations of imitation Silly Putty. Changing the ratios of polymer and sodium tetraborate solutions in your imitation Silly Putty will affect how it bounces, stretches and goos! Sodium tetraborate is an ionic molecule that acts as a linker between the long chains of the polymers (draw Figure 1 on the board). ![]() Today, we are going to follow in James Wright's footsteps and use poly (vinyl alcohol) and sodium tetraborate (borax) solutions to make a slimy polymer, resembling Silly Putty! Did you know that poly (vinyl alcohol), the main ingredient in Elmer's Glue, is a long chain of repeating ethyl alcohol monomers? You can think of these ethyl alcohol monomers -(CH 2-CHOH)- as long strands of spaghetti. Although his invention of was not found to have good practical uses, Silly Putty did find success as a children's toy in 1949! This began to hamper war production efforts, especially the manufacture of tires and boots. During World War II, Japan occupied many of the natural rubber manufacturing countries in the Far East and cut off supply to the US. Who has played with Silly Putty?
