On a photo of a flower, for example, the Photos app is able to compare it to other flower images on the web, providing a possible identification for the flower type. Some photos will also have a sparkle next to the Info button, which means there's info that you can see in Look Up mode. This interface can be used to add captions and to see the location where a photo was taken, plus there is an option to adjust metadata such as date captured. Prior to now, there was no way to view this information directly in the Photos app on the iPhone, so you had to use either a third-party app, a Shortcut, or a different device to view it.

![]() Like the peanut butter, I use whatever type of oats I have on hand, which is usually either old-fashioned oats or quick oats.īoth old-fashioned and quick oats work well in this treat, though I do prefer the quick oats as they seem to mix a little better. I recently switched to 100% Peanuts peanut butter from Walmart for use in dog treats but I’ve used whatever I have in my cupboard in the past. When choosing a peanut butter to use it’s best to use all-natural peanut butter with no added sweeteners.īut you can use any brand you want as long as it does NOT contain xylitol. It also provides an added flavor that most dogs enjoy. Peanut butter helps to hold these treats together. You can also use homemade pumpkin puree if you have some. Unfortunately, it can be confusing as they both have a picture of pumpkin pie on the can. When shopping for pumpkin puree make sure you get the can that says 100% pumpkin and NOT pumpkin pie filling. Pumpkin has many benefits for dogs and is a great source of fiber and vitamins A, C, and E. More information about the ingredients Pumpkin puree Or store in the freezer for up to 3 months. Store in the fridge and use within a week. Place them on a cookie sheet lined with wax paper or parchment paper and place them in the fridge for about an hour.Īfter they have chilled for an hour, they should hold their shape enough to be able to be placed in an airtight container for storage. I made smaller balls for Morgan (since she’s only 23 pounds). I made the larger balls around ping pong ball size for Luna (as she’s a 100-pound German Shepherd). Bite size will vary based on the size of your dog. Once combined, take a small amount of the pumpkin mixture and roll it into a bite-sized ball. You can start with a spoon, but eventually, it becomes easier to just mix with your hands. ½ cup creamy peanut butter (make sure it doesn’t contain xylitol)Ģ ½ cups oats, Old-fashioned or Quick Oats DirectionsĬombine all the ingredients in a large bowl and mix until well combined. Ingredient listġ cup pumpkin puree (not pumpkin pie filling) fresh or canned is fine These homemade dog treats are made with just three ingredients: pumpkin puree, peanut butter, and oats.Īlways consult your veterinarian before giving your dog new foods. How to make no-bake pumpkin and peanut butter dog treats That means if you click on them and buy something, I may receive a small commission at no cost to you. No-Bake Peanut Butter and Pumpkin Dog Treats have only three ingredients and are easy to make, no oven needed. While we shouldn’t share our pumpkin or pumpkin spice flavored foods with our dogs, we can make them their own pumpkin treat. Including pumpkin spice (the nutmeg in it is toxic to dogs). Pumpkin cake, pumpkin bread, pumpkin bars… all are good.īut none of these can be shared with our dogs as most baked goods (including pumpkin baked goods) have too much sugar and other things that dogs shouldn’t have. While I’m not a big pumpkin spice fan, I do enjoy baking with pumpkin. I’ve heard so much about pumpkin spice this or that on the radio for the last week or so already. Fall is here (well almost here but the weather sure feels like it is fall) and that means pumpkin spice time. ![]() This is the case with legumes (such as beans, lentils, and peas) and some types of nitrogen-fixing bacteria. ![]() Some mutualistic symbiotic relationships involve one species living within another. ![]() The plant uses the ammonia for growth and development, while the bacteria receive nutrients and a suitable place to grow. Nitrogen-fixing bacteria live in the root hairs of legume plants where they convert nitrogen to ammonia. Symbiotic root nodules on alfalfa containing nitrogen-fixing Rhizobium bacteria. The algae or cyanobacteria partner is capable of photosynthesis and provides nutrients for the fungus. The fungus provides a safe protective environment within the lichen tissue for the algae and/or cyanobacteria to grow. Lichens can be found in extreme environments like deserts or tundra and they grow on rocks, trees, and exposed soil. The fungus is the major partner in this mutualistic relationship that allows lichens to survive in a number of different biomes. Lichens are complex organisms that result from the symbiotic union between fungi and algae or between fungi and cyanobacteria. The fungus receives nutrients obtained from the photosynthetic algae or bacteria, while the algae or bacteria receive food, protection, and stability from the fungus. Lichens result from the symbiotic union between fungi and algae or fungi and cyanobacteria. Ed Reschke /Oxford Scientific/Getty Images Lichens are sensitive to atmospheric pollution. This species is very common and grows on bark of all kinds of trees in partial shade or sun. Since sharks also provide transportation for remora, the fish are able to conserve energy as an additional benefit.Ī lichen is a symbiotic association of an alga and a fungus-mutualism. In exchange, the remora fish get free meals and protection from the shark. This reduces the shark's exposure to bacteria and other disease-causing germs. Remora also consume unwanted scraps left over from the shark's meal, which helps to keep the shark's immediate environment clean. Sharks even allow these fish to enter their mouths to clean debris from their teeth. Remora provide a beneficial service for the shark as they keep its skin clean of parasites. Measuring between 1 to 3 feet in length, remora fish use their specialized front dorsal fins to attach to passing marine animals, like sharks and whales. Remora receive food, while the shark receives grooming. Remora are small fish that can attach to sharks and other large marine animals. The two have a mutualistic symbiotic relationship. This lemon shark has remora fish attached to its body. Following are some examples of mutualistic relationships. Still others involve one species living within another species. Other mutualistic relationships are multifaceted and include a combination of several benefits for both species. Common mutualistic associations occur between organisms in which one organism obtains nutrition, while the other receives some type of service. In facultative mutualism, both organisms benefit from but are not dependent upon their relationship for survival.Ī number of examples of mutualism can be observed between a variety of organisms (bacteria, fungi, algae, plants, and animals) in various biomes. In obligate mutualism, the survival of one or both organisms involved is dependent upon the relationship. Mutualistic relationships can be categorized as either obligate or facultative. ![]() Photograph by Mikael Kvist/ Moment/Getty Images Clownfish and anemones live together in a mutualistic symbiotic relationship. These ocellaris clownfish are hiding in an anemone. This happens in all tests (minecraft, scaled, unscaled). What is happening now is that the higher quality pop-in is looking like low-quality repeating textures, there is no smoothing or anything. What am i doing wrong?Īnything within a certain vicinity of my flying character is normally loaded into memory as the higher quality generation instead of a less quality representation of the world.

One other interesting component of MacClean is the quarantine feature. Still, considering that these sorts of files can add up over time, keeping these new options hidden under ‘optimization tools' makes this software harder to use when compared to other Mac cleaning apps. Since its inception in 2015, MacClean developers have continued to add useful features to their Mac optimization software, with iPhoto clean, binary junk data remover, extension manager and iOS backup cleanup among some of these new additions. This uninstaller performed well in our tests, although the AppCleaner app found some traces of one Adobe app we had removed using MacClean – though we had no issues with any other uninstalled apps. UtilitiesĪlong with utilities such as the cleaning of old and large files, a duplicate finder, and a file eraser (which will securely remove any selected files, a function that Apple has disabled in the latest versions of macOS for Macs with flash storage), MacClean also includes the convenient app uninstaller. So, if you don't have a third-party Mac malware app such as MalwareBytes then you might want to restrict how often you use it, or otherwise skip it completely. This is essentially the open-source ClamAV scanning engine, which is a super-slow resource hog when run on demand. But before the scan can be initiated you'll first be prompted to install a MacClean security database and engine. One interesting feature included in the cleaning module is the function to scan your whole Mac, Application and Download folders, or a selected folder for malware. The results of the scan are then displayed in an easy-to-understand manner, along with the option to review the files the cleaning software has flagged as junk. ![]() MacClean, however, needs much more attention since it will perform scans in only the specifically chosen areas, whether that’s system or internet junk files, malicious cookies or looking for security issues on demand. Competitors such as CleanMyMac offer convenient automation processes, meaning that you only need to push one button to get information on how much disk space you are about to free up. MacClean makes it easy to remove useless junk files, but it doesn't help save time at all. It also features a script called security issue, which will analyze your computer for potential virus threats based on a third-party virus database and search engine that you'll need to download first. It also looks for app documents and private app histories, and gives users the option to remove these cache files to protect their privacy. ![]() But what makes this app particularly interesting is its ability to scan web browsers (Safari, Google Chrome, Firefox or Opera) for malicious cookies. Just like its competitors, MacClean seeks to clean your Mac of system cache junk (user cache, system cache, developer junk files and app leftovers) and internet junk data such as browsing histories, download histories, cached files and cookies. The app incorporates two main modules, cleanup and utilities, each of which has a list of actions you can take to optimize your Mac. When you launch MacClean you're greeted by a simple, basic and easy-to-understand user interface with a list of functions on the left side of the window. However, to perform a cleaning operation you will need to buy a lifetime license for as low as $7.99. In its free form this Mac optimization software will scan your computer on demand and display how much data can be safely removed from the startup disk. MacClean is a freemium app, meaning it can be downloaded and used for free, although limitations do apply. Alongside apps targeting iPhone, iPad and iPod users, such as AnyTrans (for managing file transfers), PhoneRescue and PhoneClean, MacClean is designed solely to keep your Mac clean and safe from malware. ![]() IMobie, a China-based company established in 2011, built its business around Apple's: the team of developers is focused on iOS device content management, iOS data recovery and Mac utility software.

The Modified Dot-Blot Method’s utility in informing the decision whether to evaluate PPE using ASTM F1670/F1670M-17a is demonstrated in the publication Evaluation of Apparatus Used to Test Liquid through Protective Materials: Comparison of a Modified Dot-Blot Apparatus to the ASTM Penetration Cell. Materials, test organism, and equivalent pressures were identical between the two methods, and the results were essentially equivalent. The Modified Dot-Blot Method’s utility in informing the decision whether to evaluate PPE using ASTM F1671/ F1671M-13 is demonstrated in the publication Comparing ASTM F1671 with a Modified Dot-Blot Method to Evaluate Personal Protective Materials. Note: The ASTM methods use a common apparatus that serves as a comparator for the modified Dot-Blot apparatus described here. If the PPE fails preliminary screening by this method, it may eliminate the need for evaluation by FDA-recognized standards ASTM F1671/ F1671M-13 (Standard Test Method For Resistance Of Materials Used In Protective Clothing To Penetration By Blood-Borne Pathogens Using Phi-X174 Bacteriophage Penetration As A Test System) or ASTM F1670/F1670M-17a (Standard Test Method For Resistance Of Materials Used In Protective Clothing To Penetration By Synthetic Blood), which are more resource-intensive.Īs will be described in more detail in subsequent sections, the method consists of securing a cut piece of PPE into the modified Dot-Blot apparatus, exposing the PPE to bacteriophage ΦΧ174 or artificial blood for a set time, and applying vacuum for a set time to test the ability of the PPE to resist penetration. bacteriophage ΦΧ174 (universal viral surrogate) or.The intended purpose of the Modified Dot-Blot Method to Evaluate PPE is to serve as a screening method to evaluate the barrier effectiveness of Level 4 PPE (surgical gowns and surgical drapes) against penetration by clinically relevant artificial test soils.įor a visual depiction of the apparatus, refer to Appendix A.įor step-by-step protocols for testing of PPE materials, refer to Appendix B.PPE materials (such as, gowns and drapes) and.a Dot-Blot Apparatus (for example, Whatman Schleicher & Schuell Minifold I) modified as described in Appendix A,.The physical equipment components needed to execute this method comprise: The Modified Dot-Blot Method to Evaluate Personal Protective Equipment (PPE) is a peer-reviewed method to test the barrier performance of PPE materials against viral surrogate or liquid (artificial blood) penetration.
