In August 1965, Singapore was expelled from the federation and became a separate independent country. The independent Malaya united with the then British crown colonies of North Borneo, Sarawak, and Singapore on 16 September 1963 to become Malaysia. The country achieved independence on 31 August 1957. Following three years of occupation, peninsular Malaysia was unified as the Malayan Union in 1946 and then restructured as the Federation of Malaya in 1948. During World War Two, British Malaya, along with other nearby British and American colonies, was occupied by the Empire of Japan. Malaysia has its origins in the Malay kingdoms, which, from the 18th century on, became subject to the British Empire, along with the British Straits Settlements protectorate. Located in the tropics, Malaysia is one of 17 megadiverse countries, home to numerous endemic species. The southernmost point of continental Eurasia is in Tanjung Piai. With a population of over 32 million, Malaysia is the world's 45th-most populous country. Putrajaya is the administrative center, which represents the seat of both the executive branch (the Cabinet, federal ministries, and agencies) and the judicial branch of the federal government. Kuala Lumpur is the national capital, the country's largest city, and the seat of the legislative branch of the federal government. East Malaysia shares land and maritime borders with Brunei and Indonesia, and a maritime border with the Philippines and Vietnam. Peninsular Malaysia shares a land and maritime border with Thailand and maritime borders with Singapore, Vietnam, and Indonesia. The federal constitutional monarchy consists of thirteen states and three federal territories, separated by the South China Sea into two regions: Peninsular Malaysia and Borneo's East Malaysia.

Likewise, its gravel braking is menial as it bags 3 rd position in the test over rocks. Resultantly, it presents an optimized performance in rocky terrain and gets the highest subjective score for traction on a rocky slope. This tire is specialized for exploring rocky trails due to its strengthened construction, increased lateral stability, and gravel-resistant tread design. Thus, it won’t give you as good winter performance as a specified winter tire. However, the feature that limits the winter traction of this tire is the lack of snowflake 3PMSF rating. It also performs well on icy paths as its water-removing ability is high, and its tread is silica-infused which increases its ice traction. This property is credited to open voids in between its ribs which let the tread bite over the snow and throw it backwards while moving ahead.īesides that, small sipes also make biting action more efficient, while large shoulders with scooped edges make steering on snow easier. Wrangler rolls over the soft snow proficiently due to its open tread.Ī high void ratio enables it to roam about snow areas and clean its track and tread alongside. It also enables to take turns over a mud-covered path with full control and responsiveness because the muddy substance is channeled out from deep shoulder grooves.Īlternate scooping over the outer margin also helps in throwing mud off and maintaining firm steering traction. Thus, its open tread presents a good biting ability on mud. There is massive space between its tread blocks to evacuate mud. Owing to its broad and deep grooves, mud traction of MT/R is high. How does the Goodyear MTR performs OFF road? Wrangler MT/R Mud traction Moderate- high Snow traction Moderate- high Ice traction Moderate Rock traction High Mud Terrain The outer edges of its shoulders are alternatively scooped, and the sidewall shows an aggressive design as well. Shoulder lugs have wide lateral spacing between them in which rectilinear stone ejectors are present. Thin sipes are also marked on top of its central and shoulders blocks. Its longitudinal grooves are broad as well as deep. These blocks are compactly arranged in one row while widely spaced in the other. Its central portion specifies only two ribs comprising small blocks. Goodyear MTR shows an open tread design with an asymmetric arrangement of tread elements. I'm not sure what I will be replacing them with.Specs Wrangler MT/R Tire type All-terrain, all season Usage Off-road, on-road Three-peak mountain snowflake rated (3PMSF) No Tested size LT265/75R16 Tread depth 19/32-inch Section width 10.5 inches Maximum inflation pressure 80 psi Maximum load capacity 3415 Ibs Load index 120/123 3417/3086 lbs speed rating 100 mph Approved Rim Width 7 – 8 inches Overall Diameter 31.9 inches Tire weight 55 lbs What do we see in the tire’s tread design? The on road performance has too many compromises for the way I'm using my TJR now. So, in my experience, the MTR is a great tire but I don't think I will be buying them again when the time comes. That was several months ago and it doesn't lose air. Shop told me I had to replace the tire as it would not be fixable. I got a nail in one tire at the corner near the sidewall. I didn't replace them but I added 11 oz of airsoft pellets (0.25 gr each) to each tire. Shop just told me I had to replace them-even with a lot of tread left. The tires have become impossible to balance over time. The stiff sidewalls make for a rough ride-even at 22 psi where I run them. I've never had problems with rain but standing water at highway speeds gets your attention. They're pretty good in loose snow or even somewhat packed. I've been on 35" MTRs for 7 years with kind of a love/hate relationship. Now, every selection tool has several different modes that we can use, and you will almost always find those here at the top-left. So every time you click and drag in the default behavior of the tool, you will delete the old selection and just leaving the new one. If you click and drag outside of the original Marquee, you will delete the old marquee, so the first selection will disappear, and all that will remain is our new selection. So I can just click and drag and move the marquee over to one of the other rectangles. Now, when you put the mouse cursor inside the Marquee, you are able to move it. And I can try to get an accurate selections of one of these squares, which is actually a light projection at an art installation in Amsterdam. So when releasing the space bar, I can again influence the size of the marquee. Holding down the space bar while I am still dragging them are key allows me to move the mark key to the desired spot. So being able to direct opposition is very useful. Because you will often find that you start clicking and dragging in just the wrong position. Something that's also very useful using this tool is the ability to move it as you are still drawing it. So every side is as long as every other side. If you hold down the Shift key, you constrain the proportions to a square. So you can draw a rectangle of any size and any proportion. I'm just going to click and drag and I'm going to hold the mouse down to show you some shortcuts we have at our disposal. Now, when you activate the rectangular marquee tool, you can simply click and drag on your canvas to create a selection. And the Marquee Tools are the second group of tools in the left toolbar here. So I've opened the exercise file for 0.1 rectangular marquee. We are going to get started with the rectangular marquee tool. And we will be looking at most of the selection tools at our disposal and also looking at why certain tools are better suited for certain projects. So that's what we will be looking at in this chapter. 1.1-Rectangular Marquee: Creating accurate selections in Photoshop is one of the true core skills of working with the program because using selections, we can isolate subjects from a background or we can limit editing of an image to a specific section of that image. Thanks for signing up and let me know what you think of the course in the comments.Ģ. But you will find that the techniques I showed you can be applied to any images in all situations. Every video comes with an exercise file that you can use to put what I teach you straight into practice. And I will show you how to do so quick and easy with olive Photoshop, CC's and newest features. If you want to extract the subject from the background, or if you just want to limit your editing to a single part of an image. These techniques are essential if you want to combine several images into a single composite. In these comprehensive course, I'm going to teach you everything you need to know about grading fast, accurate, and easy selections, and how to apply those selections to working with layer masks. My name is work time and I've been teaching about Photoshop for over 12 years. 1.0-Introduction: Hello and welcome to my online course about working with selections and layer masks in Photoshop CC. This research has shown that case bioconstruction by caddisfly larvae may have a destabilising effect on sand in gravel-bed rivers. Tubular case-builders (especially Limnephilidae) and dome case-builders (Glossosomatidae) were particularly important zoogeomorphic agents, using and transporting substantial amounts of coarse sand and fine gravel. As a result of both larvae crawling and case entrainment, case-building caddisfly were responsible for over 30% of coarse sand transport during low to medium discharge conditions in a gravel-bed stream. A second flume experiment found that crawling Glossosomatidae larvae transport sand vertically upwards, from sheltered interstices below gravel particles, onto the surface of armoured gravel-beds, increasing the hydraulic exposure of this sediment. A flume experiment determined that empty cases of some caddisfly species (tubular case-builders Limnephilidae and Sericostomatidae) were more mobile than their incorporated sediment, but that dome shaped Glossosomatidae cases moved at the same entrainment threshold as their constituent grains, highlighting the importance of case design as a control on caddisfly zoogeomorphology. This sediment was aggregated into biogenic particles (cases) which differed in size and shape from their constituent grains. As a community, caddisfly used a wide range of grain-sizes in case construction (0.063 mm-11 mm), and, on average, the mass of incorporated sediment was 38 g m-2, in a gravel-bed stream. Caddisfly cases varied considerably in mass between species (0.001 g-0.83 g) and grain sizes used (D50 = 0.17 mm-4 mm). The research was conducted using two flume experiments to understand the mechanisms of caddisfly zoogeomorphology (case construction and transporting sediment), and two field investigations that increase the spatial and temporal scale of the research. This thesis investigates, for the first time, the effects of bioconstruction by case-building caddisfly on fluvial geomorphology. Case-building caddisfly have the potential to modify the distribution and transport of sediment by: 1) altering sediment properties through case construction, and 2) transporting sediment incorporated into cases over the riverbed. Caddisfly larvae of most species build cases from silk and fine sediment at some point in their lifecycle. The large number of samples required at our study sites to reach a high level of sampling completeness suggests that the diversity of ground-dwelling invertebrates in dry riverbeds has probably been underestimated in previous studies.Ĭaddisfly (Trichoptera) are an abundant and widespread aquatic insect group. Differences in the performance of pitfall traps and quadrats in dry riverbeds may be due to the absence of vegetation, to the large range of taxa considered, and to diel movements of some taxa. Rarefaction curves indicated that eight to eleven pitfall traps/100 m2 were necessary to collect most of the common taxa in the study sites. Among-sites differences in invertebrate composition were greater in pitfall-trap samples than in quadrat samples. Among all taxa collected, 80% were exclusive to pitfall traps and 4% to quadrat samples. On average, pitfall-trap samples contained 3.5 times more taxa than quadrat samples, and pitfall traps required less time to collect as many taxa as quadrats. Sampling efficiency and completeness and detection biases associated with pitfall-trap and quadrat samples were compared at six sites in the dry beds of two New Zealand rivers. The distribution and ecological roles of ground-dwelling invertebrates colonizing dry beds of temporary rivers are poorly known, due in part to the lack of tested sampling methods. As they kiss on the couch in the aftermath, Alicia and Eliza suggest that perhaps this can be their new Christmas tradition.Eliza Ibarra In Pure Seduction 9:28 TXXX Solo MILF HD Videos When the guys can't hold back a moment longer, they pull out and pop all over the girl they're fucking to leave both ladies cum covered and oh so satisfied. Tyler makes Eliza moan, while Jay does the same for Alicia. The girls swap partners one last time and lay on the couch with their heads adjacent so they can caress each other's upper bodies as the guys bring them home one last time. On her back on the couch, Alicia opens wide to welcome Tyler back inside. When the foursome splits back into couples, Eliza finds herself riding reverse cowgirl on Jay's hard dick. Jay arranges himself between Eliza's thighs, giving it to his girlfriend while guiding one of her cute feet up so he can run his tongue over the tender arch to really make Eliza moan. That pseudo-69 position lets Tyler slam home into Alicia's greedy fuck hole. The couples switch it up again, with Eliza laying on her back with Alicia climbing onto her face to ride her hot tongue. The position lets Eliza lean forward to lick at Alicia's clit and tongue her hard nipples. Meanwhile, Jay sits on the couch so Alicia can mount him in reverse cowgirl. Getting on her hands and knees on the couch, Eliza invites Tyler to slide into her slippery twat. The girls keep on sucking until they're both ready for something more hardcore. The guys are committed now, which makes them enthusiastic participants. Rubbing and stroking, they lean in and open wide to begin coordinated blowjobs. Eliza pulls Tyler's cock out while Alicia does the same for Jay's. Once the girls are assured of their mutual conquests, they get the men to their feet. Kissing and stroking, they work each man into a sexual frenzy from which there's no coming back, which makes the upcoming couples swap beautifully inevitable. Climbing into each other's boyfriends' laps, the girls make themselves cozy. Eliza goes to Tyler and Alicia goes to Jay where they're seated on the couch. The guys could have happily just watched their girlfriends necking, but Eliza and Alicia want so much more than that. To clear up any possible misunderstandings, Eliza and Alicia capture one another's lips in a hot kiss that leaves no doubt that this isn't the first time they've gotten together. Before long, the girls have reappeared in Christmas coordinated lingerie. They leave the room together, leaving Jay and Tyler to speculate about what their girlfriends might have cooked up. The couples have been friendly for a while, but this Christmas meetup is about to be really special, because on top of all the other gifts getting exchanged Alicia and Eliza have a special present for their boyfriends.Īfter getting the men settled by the Christmas tree, Eliza and Alicia announce they have one last present from themselves for the guys. What could be hotter for Christmas than learning your hot girlfriend is also into your friend's hot girlfriend?

Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. Our Sun will stay in this mature phase (on the main sequence as shown in the Hertzsprung-Russell Diagram) for approximately 10 billion years. Main Sequence StarsĪ star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. Observations with NASA's Chandra X-ray Observatory provided a likely explanation: the interaction between the young star's magnetic field and the surrounding gas causes episodic increases in brightness. When observers around the world pointed their instruments at McNeil's Nebula, they found something interesting - its brightness appears to vary. In January 2004, an amateur astronomer, James McNeil, discovered a small nebula that appeared unexpectedly near the nebula Messier 78, in the constellation of Orion. In some cases, the cloud may not collapse at a steady pace. Not all of this material ends up as part of a star - the remaining dust can become planets, asteroids, or comets or may remain as dust. Smith (University of Arizona)Īs the cloud collapses, a dense, hot core forms and begins gathering dust and gas. The observations of Eta Carinae's light echo are providing new insight into the behavior of powerful massive stars on the brink of detonation.Ĭredit: NOAO, AURA, NSF, and N. Three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs this would explain why the majority the stars in the Milky Way are paired or in groups of multiple stars. Known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. As the cloud collapses, the material at the center begins to heat up. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. A familiar example of such as a dust cloud is the Orion Nebula. Stars are born within the clouds of dust and scattered throughout most galaxies. Consequently, the study of the birth, life, and death of stars is central to the field of astronomy. Moreover, stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may coalesce about them. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. |
