![]() This allows RNA polymerase to bind to the promoter and freely transcribe the three genes, allowing the organism to metabolize the lactose.Įukaryotic cells, in contrast, have intracellular organelles and are much more complex. When lactose is present, an end product of lactose metabolism binds to the repressor protein and prevents it from binding to the operator. Thus very little of the protein products of the three genes is made. When there is no lactose present, a protein known as a repressor binds to the operator and prevents RNA polymerase from binding to the promoter, except in rare cases. The operon also contains a promoter sequence to which the RNA polymerase binds to begin transcription between the promoter and the three genes is a region called the operator. When lactose is present, the genes are transcribed and the bacterium is able to use the lactose as a food source. When lactose is not present in the bacterium’s environment, the lac genes are transcribed in small amounts. ![]() The lac operon is a stretch of DNA with three adjacent genes that code for proteins that participate in the absorption and metabolism of lactose, a food source for E. coli in the 1950s and 1960s by French researchers and is called the lac operon. The first example of such control was discovered using E. Therefore, in prokaryotic cells, the control of gene expression is almost entirely at the transcriptional level. When more protein is required, more transcription occurs. All the subsequent steps happen automatically. As a result, the primary method to control what type and how much protein is expressed in a prokaryotic cell is through the regulation of DNA transcription into RNA. When the protein is no longer needed, transcription stops. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different fashions.īecause prokaryotic organisms lack a cell nucleus, the processes of transcription and translation occur almost simultaneously. To understand how gene expression is regulated, we must first understand how a gene becomes a functional protein in a cell. Prokaryotic versus Eukaryotic Gene Expression Malfunctions in this process are detrimental to the cell and can lead to the development of many diseases, including cancer. The control of gene expression is extremely complex. Unicellular organisms, both eukaryotic and prokaryotic, also turn on and off genes in response to the demands of their environment so that they can respond to special conditions. In addition, cells will turn on or off certain genes at different times in response to changes in the environment or at different times during the development of the organism. Each cell also has many genes that are not expressed, and expresses many that are not expressed by other cells, such that it can carry out its specialized functions. All cells have certain basic functions they must perform for themselves, such as converting the energy in sugar molecules into energy in ATP. These differences are a consequence of the expression of different sets of genes in each of these cells. For example, a muscle cell is very different from a liver cell, which is very different from a skin cell. ![]() For this to occur, there must be a mechanism to control when a gene is expressed to make RNA and protein, how much of the protein is made, and when it is time to stop making that protein because it is no longer needed.Ĭells in multicellular organisms are specialized cells in different tissues look very different and perform different functions. Whether in a simple unicellular organism or in a complex multicellular organism, each cell controls when and how its genes are expressed. The process of turning on a gene to produce RNA and protein is called gene expression. All organisms and cells control or regulate the transcription and translation of their DNA into protein. Understand that eukaryotic gene expression occurs at the epigenetic, transcriptional, post-transcriptional, translational, and post-translational levelsįor a cell to function properly, necessary proteins must be synthesized at the proper time.Describe how prokaryotic gene expression occurs at the transcriptional level.Discuss why every cell does not express all of its genes.Learning Objectives By the end of this section, you will be able to:

6/2/2023 0 Comments Raw power 4 u![]() ![]() Larger, heavier vehicles such as SUVs and trucks may require the power of a V6 to operate while smaller compact cars will often offer both varieties. If the economy is your top priority, a four-cylinder is likely the best choice for you.Ī V6 engine will be able to produce a greater amount of power at a quicker pace and will be much more responsive to each tap of the gas pedal, able to quickly accelerate to high speeds. With a V6, you find yourself frequenting the gas station more regularly, and you may also end up with higher insurance premiums. In the same model vehicle, you will be paying a greater price at the dealership for a V6 over a four-cylinder engine, which will give you more power with less fuel efficiency. More power requires more fuel, which means you will end up paying significantly more for gas over the lifetime of your vehicle. This often comes at a tradeoff in fuel efficiency. In general, the more cylinders an engine possesses, the faster power can be generated. Many car models are offered in both four- and six-cylinder options. An average small to medium sedan or coupe typically requires a minimum of four cylinders to operate while much larger vehicles such as semi-trucks may require up to 12. These products are not intended to diagnose, treat, cure, or prevent any disease.Your cylinders are critical elements of your engine’s ability to convert raw fuel into power, which it does through tiny, controlled explosions.

I’d already made the repairs discussed in the past (relocate gear on spline with adhesive). The gear hub (the part between shaft hole and the bottom of the gear teeth) is undersized and can’t withstand the expansion force created by the shaft spline. The gear in question, the one that slips off of the spline on the shaft, is the planned obsolescence component on this printer. I’d purchased another one of this model (for parts only - $25), and have used it to replace a number of components. I’ve used this printer for lots of photo proofing/printing (as well as regular printing), and have invested more than enough time and expense installing a CIS System and calibrating color output many years ago. Specifically, I’m dealing with a C309A Photosmart. Seems this discussion has strayed to a number of different models it may be a somewhat universal design however and the issue probably applies to more than one. If the rubber pick-up drums still slip, repeat the cleansing operation. Print a test page (e.g., a blank Word document to avoid wasting ink). Let the water evaporate and reassemble the duplex unit. This is tricky since you need to reach into the printer from the back (left). Now take another moist Q-tip and swipe the rubber-covered grooved paper pick-up drums clean in a similar fashion. Rotate the axis upward (only possible way) to clean the next section of the 4 rubber drums. Clean these with a Q-tip moistened (not soaked) in clean water, and move from left to right. You can now see 4 rubber drums on an axis. Unplug the printer's power cord, detach the duplex unit at the back (push to the left and pull back to disengage the unit from the printer). If you see the paper pick-up drums slip on the paper, then you may have better luck. Here's a written summary based on my experience: There are image and video instructions available from HP. Scenario 2: the pick-up drums do roll, but they slip on the paper Probably the entire printer must be torn down, and I don't expect you will be able to easily fix the excess play on the paper pick-up mechanism that drive the rubber rolls when pressed on the stack of paper. I suppose that because of excess play (programmed obsolescence?) eventually the cogwheels that drive the drums will slip. ![]() When the drums touch the paper, they simply don't rotate. When lifted, you will be able to rotate these drums in one direction. When printing, they are dropped to the top of the paper stack and will engage to separate the topmost sheet off the stack. When not printing, these drums are lifted. It looks like there is too much play in the paper pick-up unit (at the rightmost end inside the printer) on which both pick-up drums are mounted on a single arm. You most likely hear a grinding noise of plastic cogwheels slipping when the printer tries to feed a sheet of paper. Scenario 1: the pick-up drums do not roll, you hear a grinding noise Thanks much for steering me in the right direction. My printer had little use as I have a second one that I use for everyday printing, so, wanted to save the hp 310 as my good scanner/color/printer. Now works great! Hardest part was manipulating the dabbing of the epoxy on the spline due to working with mirror image. Waited until next morning to try printer. Very carefully slid the gear with fingers back on the shaft spline viewing that it was centered on the mating gear. Mixed some two part epoxy and carefully dabbed small amount on the shaft spline until about 100% coated. Then slid the gear down & off the spline. (can move the gear by hand back in line with the gear train and try once to see if it fixes problem). ![]() One small plastic gear slid off the steel shaft 'spline' not engaging drive train. Taped drop light to now top of printer looking at the mirror/gear train. ![]() Positioned small flat mirror angled on its edge to view gear train. 6/2/2023 0 Comments Sally face game cryotatic![]() Unravel the sinister mysteries of Sally's world to find the truth that lies hidden beneath the shadows. Check out that amazing artwork by BessesseN, who is absolutely killing it 85. ![]() The final deck will have all major and minor arcana cards. Not only is this the most scariest indie game, this is also by far one of the scariest games I've played. Sally Face - Episode One Delve into a dark adventure following the boy with a prosthetic face and a tragic past. A peek at the Sally Face Tarot Deck being developed. ![]() But before you play this, I would like to let you know in order to prepare yourself that the game will contain a ton of dark twists and the intensity you will have to follow. But for those that are fans of the genre, this is definitely a must play. Of course, this game wouldn't be for everyone since I know there will be those that wouldn't handle the horror the game has. And to top it all off, very disturbing indie graphics that's in right levels and sticks to the genre the game is mostly about. Along with the story for the game to tell is both unpredictable and intense and likable characters. And what I would mean by that is when it comes to some instances where you get to play Gear Boy games that's made for the game, having the gameplay have enough to make the secret ending contain both shocking twists and different types of gaming styles we would see Sally Face enter in the final act, which I won't spoil by the way. Not only is Sally Face one of the scariest game that had been created, but also has an excellent direction combining horror and classic indie gaming. In the first episode, Strange Neighbors, Sally Face and his father move into an apartment filled with odd tenants and an unfortunate crime scene. And that's what makes it an awesome game. Sally Face Review A Dark Mystery is Unfolding.Delve into an unsettling adventure following the boy with a prosthetic face and a tragic past. It's not all the time we would see an indie game go into that direction, but this game is absolutely scary and disturbing. 6/1/2023 0 Comments Engineers black book![]() Practical and pocket sized, making it easy to be carried around and convenient to use in the shop and around the machine, unlike other larger reference books. ![]() Reviews arent verified, but Google checks for.

6/1/2023 0 Comments Typinator alternative![]() But TextExpander is much smarter than that. Google Mail has recently introduced a canned response feature, and although useful, I find it resembles my old system of saving multiple draft emails, the content of which can be copied and pasted into new emails. It’s in these subtle differences that TextExpander excels. About 90% of each message is usually the same, but requires some element of personalisation (which is important to good customer service, anyway). I’m not talking about ‘canned responses’ per se there’s usually something a bit different about each instance, whether that be responding to new client work requests, asking potential clients to clarify timeline and budget, or respond to 8 Faces customers whose copy never arrived. Like many people, I find myself writing the same thing over and over and over again, with very subtle alterations. In other words, it’s the law of averages. My completely non-scientific research has found that the number of times one writes the same thing is explicitly tied to the number of emails one receives. So, for the benefit of those who have never considered it - and for Sarah, for whom I promised to write this article - I’m going to explain why this is an essential app for anyone who receives a high volume of email, or regularly has to write similar responses, or makes dumb typos, or just wants to get a bit more time for the important things in life, like quaffing delicious Belgian beers. From the first hour of using the app, I knew it would change the way I write and - most importantly - allow me to finally conquer email. I only came across it properly when reading Frank’s post about his Mac set-up. I think in the back of my mind I was aware of it, but had assumed it was something to do with a code editor. It’s been around for years and I’d managed to completely miss it. I’ve been using it for just over a month and I honestly don’t know how I could now live without it. Without a doubt, TextExpander is that tool. So when a tool comes along to help me get email out of the way a lot quicker, I’m excited. It’s nothing to do with the way email works it’s purely down to the volume of email I receive. I despise it because it eats up so much of my time. It’s not that I have any particular problem with the medium in fact, I’m not even one of those people that believes it should be replaced with a radical alternative. Let me get this out there right away: I hate email. 6/1/2023 0 Comments Cat hide out![]() ![]() Use Food and Treatsįood is a great go-to method to encourage your cat to come out of hiding. Adding another cat tower near where your cat is hiding can coax them out. Typically, this means added vertical space.Ĭats feel safest high up, so they can have a clearer view of any predators. The best way to do that is to create a clear, easy way for them to escape. If your cat is going to come out of hiding, they need to feel safe. You can use a sound machine, calming music, or even the TV to block out sounds from outside that could be scaring your cat like thunder, fireworks, or loud car noises. If you can’t remove the stressor, try to block it out in some way. Interesting READ Why Do Cats Hide Their Poop? How Do I Get My Scared Cat Out of Hiding? Cats hide when they’re feeling sick or they’ve been injured, so you should check on your cat as quickly as possible. If nothing in your cat’s environment has changed, but they’re still hiding all day, they may need medical attention. They may even stay hidden for a couple of days until they feel more comfortable in their new environment. If you’ve just adopted a new cat and brought them home for the first time or you’ve recently moved to a new place, it’s perfectly normal for your cat to hide all day. In these cases, they’ll need a little extra space and patience but will eventually adjust. However, if your cat is in a new home or environment, they might hide for a couple of days while they get used to the new smells and new space. With a little coaxing and reassurance, your cat will come out in no time. If your cat was only scared by something small, like a loud noise outside, they won’t stay hidden for long, typically an hour or two. Until they can feel safe again, they will continue to hide. That could be why your cat is not playful anymore, for now. Ultimately, your cat is hiding because they’re scared and don’t feel safe in their environment. The time it takes your cat to come out of hiding will depend on their personality, environment, and what scared them in the first place. V) Should You Be Worried About Your Hiding Cat? How Long Does it Take for a Cat to Stop Hiding? 6/1/2023 0 Comments Topaz sharpen ai test![]() I’ve seen it happen to one of my friends. ![]() Accidentally setting the focus method to manual is a possibility, too. Some photographers prefer using manual focus in some situations but forget to switch back to autofocus. This issue arises when the autofocus is not accurate, especially when photographing moving subjects and using the continuous-focus features. Similar to having poor equipment, if the focus is off, then the image will come out blurry. Similarly, a method photographers use to stay within their budget is to pay for less-expensive equipment and correct any image issues in photography software. And even with high-end photography equipment, images can still improve with a little post-processed sharpening. And we all can’t afford to pay for a full-frame camera or a Canon L Series lens. The quality of a lens or image sensor can impact the sharpness in addition to noise. This is common in expedition safaris on overland vehicles or a boat cruise through the Galapagos Islands. Furthermore, many photographers find themselves in a moving vehicle. Let’s not forget about children running around and playing. There are many scenarios where our subjects are moving. This can be lions running across the savanna, sprinters racing along the track, or an airplane landing on the runway. We live in a world where many of our photography subjects are moving. Reasons a Photograph May Not Come Out Sharp 1. However, it does come with Photoshop and Lightroom plugins. It a standalone application that mainly focuses on sharpening.

But if you would rather trade convenience for outright performance, Topaz Sharpen AI is the way to go. Overall, SuperSharp AI is a good-not-great image sharpener conveniently integrated into Luminar Neo. But unlike Topaz Sharpen AI, SuperSharp AI offers the convenience of being built into Luminar Neo, thus saving you from bouncing between multiple applications. Yet SuperSharp AI’s biggest problem is Topaz Sharpen AI which is better by every measure except price. In contrast, the Face Enhancer AI is high impact but not necessarily in a way that pleases the eye. Furthermore, only the Low setting remains useful, with the Middle and High settings all but guaranteed to produce awful results.īut speaking of settings, you can now choose between Universal sharpening and Motion Blur correction, yet I found both to produce similar results. First, Supersharp is quite slow and demands patience when processing your images. This is not entirely bad news since even in its earliest days SuperSharp AI could deliver good results. Read ON1 NoNoise 2023 Review.ĭespite several updates, SuperSharp AI continues to deliver performance similar to its first iteration. Furthermore, Tack Sharp AI is the fastest AI sharpening tool I’ve ever used. However, TackSharp AI offers more adjustment and, thus, creative freedom. In terms of results, both yield decent results so long as you show restraint with the settings. Tack Sharp AI is packaged with the wonderful ON1 NoNoise 2023, and like SuperSharp AI, TackSharp AI is in its first iteration and a little rough around the edges. Read Topaz Sharpen AI Review for more information. But if you crave results over convenience, Topaz Sharpen AI is more capable. Of course, you can use SuperSharp AI within Luminar Neo, whereas Topaz Sharpen AI demands an extra step. ![]() Topaz Sharpen AI is superior to SuperSharp AI in terms of usability, flexibility, speed, and results. I consider Topaz Sharpen AI and Topaz Photo AI the best in the business that has not changed. Supersharp AI Compared SuperSharp AI vs Topaz Sharpen AI As a result, I find the Middle and High settings entirely redundant. Switching up to Middle or High produces extremely harsh results. Strangely, I only Low the only usable setting. The rendering process will repeat if you switch between Low, Middle, and High sharpening or engage Face Enhancer AI. In terms of speed, SuperSharp AI took, on average, between 10 and 25 seconds to sharpen an image. ![]() Member of the CFA Breeder Referral program.
