![]() When asked whether the Democrats could keep the House, Biden said there was "a possibility," but acknowledged it would be close. Several key Senate races, including those in Nevada and Arizona, remain too close to call. Though Democrats are expected to lose control of the House of Representatives, control of the Senate is still up in the air. Raphael Warnock and Herschel Walker are going to a runoff in Georgia The Slotkin-Barrett race was among the most expensive House contests nationwide, with more than $27 million in spending by the campaigns and outside groups.Elections Sen.

She defeated Republican Tom Barrett, a state senator and Army veteran. Elissa Slotkin narrowly won a third term in the 7th District, which includes Lansing, the state capital. He has also stressed his willingness to work across party lines, and promised to make improvements in public safety and education. In a region heavily dependent on agriculture, he’s been critical of state water management and puts water and agriculture at the top of his issues list. His opponent, Democrat Adam Gray, is a state legislator known as a moderate. The top finisher in the June primary was Republican John Duarte, a businessman and major grape and almond farmer whose top priorities include obtaining adequate water supplies for farmers in the drought-wracked state - a perennial issue in the Central Valley - along with addressing inflation and crime. That provides a possible opening for the GOP, despite the 14-point Democratic registration advantage. But the most likely voters tend to be white, older, more affluent homeowners, while working-class voters, including many Latinos, are less consistent in getting to the polls. Like other districts in California’s farm-belt region, the 13th District has a prominent Democratic tilt and a large Latino population. Hodge was seen as a rising star in Democratic politics but was hampered by the slight Republican registration advantage in the wealthy 1st Congressional District that covers parts of northeast Phoenix, Scottsdale, Paradise Valley and Fountain Hills. Schweikert survived a second straight election where he was dogged by ethics issues, following violations of campaign finance rules and laws barring the use of congressional staff for campaign work. David Schweikert defeated Democrat Jevin Hodge to gain a seventh term representing the northeast Phoenix suburbs’ 1st District. ![]() Tap or click for a detailed race breakdown:ĪZ-1: David Schweikert (R) wins reelection Here’s a look at how some of the key races are turning out.

![]() Marine organisms have been less explored than mammals and microorganisms even though there are higher probabilities to find enzymes that have different specifics towards non-natural substrates in those environments. The sea anemone Condylactis gigantean is a representative of this family. Recent studies about marine coelenterates venom have demonstrated affinity to that from snakes, based on the pharmacological properties they possess, and the place where this enzymatic activity has been described for some species. In spite of their wide distribution in nature, most of these enzymes have been isolated from snakes, bees and scorpions venoms, as well as from pancreas tissues of mammals and membranes for example, those of mitochondria from hepatic tissues. These enzymes are widely spread in nature and their functional versatility and usefulness have increasingly conditioned their use in Specialized and Applied Biochemistry as well as biotechnological, pharmaceutical, and general industries such as food industry, where a highly purified enzyme is not always needed. It also reveals maximum activity when the substrate is organized in large molecular aggregations such as micelles. These enzymes yield a lyso derivative (lysophospholipid) and a free-fatty acid molecule, which is able to hydrolyze both natural and synthetic phospholipids regardless of the nature of the fatty acids in the molecule. ![]() Phospholipases A 2 (PLA 2) are esterolytic enzymes with high substrate and bond specificity for the hydrolysis of the sn-2 position of phosphoacylglycerols. Keywords: affinity, phospholipase A 2, Condylactis gigantea, sea anemone, protein purification. These components are produced with molecular weights between 1800, and at least one component possessing phospholipase A 2 activity. By means of the above-mentioned support, purification of three protein-based components can be carried out. The phospholipase A 2 activity was corroborated by using qualitative TLC and a fluorogenic substrate. PLA 2 purification from the sea anemone Condylactis gigantean is conducted through a chromatographic affinity support MANA-Sepharose CL 4B with covalently immobilized phosphatidylcholine egg. This research study aims to test a two-step purification procedure for phospholipases A 2 (PLA 2) to filter enzymes for further characterization. Marine coelenterate venom is composed of complex mixtures of several substances, mainly of proteins, for which phospholipase A 2 activity has been described. Palabras clave: cromatografía de afinidad, fosfolipasa A 2, anémona marina, Condylactis gigantea, purificación de proteínas. Dicho soporte cromatográfico permite que en un protocolo de purificación de solamente dos pasos se obtengan tres componentes proteicos de pesos moleculares entre 18000 y 14000, con al menos un componente que posee actividad fosfolipásica A 2. ![]() Se muestra la purificación de FLA 2 en un soporte cromatográfico de afinidad con fosfatidilcolina de huevo inmovilizada covalentemente para la purificación de fosfolipasas A 2, a los que se les comprobó cualitativamente la actividad fosfolipásica A 2 por cromatografía en placa (TLC) utilizando sustrato marcado con fluorescencia.

Protocolo de purificación en dos etapas de fosfolipasas A 2 a partir de la anémona marina Condylactis giganteaĪ Two-Step Purification Procedure of Phospholipases A 2 from the Sea Anemone Condylactis gigantea ![]() I noticed that it’s much easier to fill the shape of the blackberry with the small elements, starting with the bottom row. ![]() The rows are fitting closely to each other. Just imagine that the center of each drupe is sitting on the line you drew in the previous step. The reference lines are helpful for adding the rows of the drupes. With an HB pencil, I draw a rough shape of the blackberry then I add the parallel, slightly curved subsidiary lines.īerries like blackberries are composed of a cluster of small drupes around a central stem. It’s important to leave the highlights because a cherry is a smooth, glossy object. Then I add some graphite strokes to the stem and mark the drop shadow. I accentuate the hollow and the sides of the cherry with the contour hatching. I add a small hollow to the upper part of the cherry and refine the stem. This shape resembles a circle with a narrowed bottom part. I draw the shape of the cherry, using the HB pencil. This drawing already looks as if we’ve worked on it for a long time! 3. How to Draw a Cherry Step 1 Please be sure to leave a highlight on the upper part of the strawberry. I also emphasize the small hollows (where the seeds are located) and then add the drop shadow. I accentuate the sides of the strawberry, leaving the thin lines of the reflected light, and darken the leaves. It’s time to apply the hatching, using a 3B pencil. They arrange themselves in a staggered order. I soften the subsidiary lines with an eraser, so that they are barely visible, and draw the seeds. Our goal is to make an illusion of volume, so the lines should be slightly bent. I also add the subsidiary lines they will help us to allocate small seeds on the fruit’s body. I refine the shape of the strawberry and the contours of the leaves. Then I add the shapes of the leaves and the stem. With an HB pencil, I draw the rough shape of the strawberry. However, for the sake of this tutorial, let’s close our eyes to this fact. Technically, a strawberry is not a berry-it’s an aggregate fruit. If you don’t like using your own hand, you can get a blending stump or an ordinary cotton bud. Human skin has natural oils, so your drawing may get dirty. Please be sure that your hands are clean and dry before you make anything like this. To do that, I use my finger, gently rubbing the end of the hatching sample. Sometimes it’s great to smooth over the look of the graphite strokes, making them blurry. Try to vary the pressure and layer the graphite strokes you can get a dark surface which will seem almost black. I’m making lines with soft rubbing strokes, holding my 3B pencil at an angle. Let’s create a beautiful, velvety-looking texture. The lines made with the 3B pencil are darker and more intense, so this tool is the optimal choice for shading. The HB pencil leaves lighter marks on the paper, and we’ll use it mostly for creating the initial contours and designing the drawing. In my image, the HB sample is on the left, and the 3B is on the right. We have two types: an HB and a 3B.Ĭreate two samples of simple parallel hatching, just to observe how they look next to each other. Let’s compare the possibilities of our pencils. Step 2Īnother important technique for creating an illusion of three-dimensionality is contour hatching.Īs you can see in the image below, the lines are slightly bent, as if they are repeating the contours of an object. The first type of hatching is a group of straight lines that have the same direction and approximately equal length. We’ll observe different ways of applying strokes and provide a starting point for developing your skill set. This part of the tutorial is devoted to the tips and tricks of using graphite pencils. In order to complete this tutorial, you'll need the following equipment:ġ. How to Draw With a Graphite Pencil Step 1 ![]() Nothing benefits an artist more than thoughtful observation and daily practice! What You Will Need To understand and repeat the steps, you just need to become familiar with the hatching techniques and observe my illustrations closely. You don't need anything fancy to complete this tutorial just two pencils, an eraser, several sheets of drawing paper, and, of course, a desire for experimenting with your art supplies and creativity!Ī background in drawing is desirable but not obligatory. We’ll also learn to apply different types of hatching to achieve impressive results. In this tutorial, I’ll show you an easy and quick way to sketch with graphite pencils. ![]() Basic but hearty Creole and international meals are served by the helpful crew in the dining area on the main deck.Many experienced divers consider liveaboards and dive safaris as the only way to truly enjoy a diving vacation, especially if heading to remote destinations such as the Similan Islands in Thailand or Osprey Reef in Australia’s Coral Sea. This feature also allows for a safe and comfortable transfer from the tender boats to the main vessel. The stern of the vessel has a set of stairs leading down to a large swimming and fishing plat-form. The lower deck’s primary function is to store the tender boats and fishing tackle. This area is perfect for sundowners and socializing. On the mid-deck there is a spacious partially-covered seating area with magnificent views that is used often by guests. Both the cabins and indoor dining areas are fully air-conditioned, allowing guests a chance to relax in a comfortable environment after a long day’s fishing on the flats. There is also a comfortable salon and dining area. Each cabin has an en-suite shower and flush toilet. It is a four-level vessel and can accommodate 12 anglers in seven snug guest cabins situated either on the middle, main or lower deck. The ship is a bit rustic, but it is large, spacious and extremely stable, making it a perfect base from which to explore the remote outer atolls of the Seychelles. The Mayas Dugong is an ex-research vessel that has been upgraded and modified into a mothership specializing in long-range fly fishing expeditions. Guests will often spend long periods away from the boat, making this a physically rigorous trip. All anglers will spend the majority of their time wading. During a specific shift in tides they might make the call to look for milkfish, and during slack tide they might decide to wind-drift through coral heads blind casting for a wide range of hard fighting fish including grouper and bluefin trevally. When the conditions offer minimal tidal movement they might choose to spend the day walking the most productive flats for bonefish, permit, triggerfish and bumphead parrotfish. When the tides are big, they might elect to spend most of the day targeting giant trevally. Due to their intimate knowledge of tides and fish behavior, each day the guides will decide which type of fishing to focus on. ![]() The mothership carries four large sea-worthy skiffs, each captained by an experienced South African guide, that fish three per boat. The Providence fishing program is based on 12 anglers. Add to that a chance at Napoleon wrasse, Bohar snapper, barracuda, sailfish and multiple species of tuna and it won’t take long to recognize this as one of the greatest multi-species destinations our sport has to offer. Anglers can expect to target enormous giant trevally, bonefish, triggerfish, Indo-Pacific permit, milkfish, and bumphead parrot-fish. Providence offers fly fishermen the opportunity to wade and sight fish a possible 29 miles of pristine sand and turtle grass flats, an enormous lagoon system as well as the numerous channels which link these structures to the Indian Ocean. The sheer size and amount of habitat, both on the flats and offshore, create an endless array of angling options. For the consummate saltwater fly fishing professionals and explorers at Fl圜astaway, this complex is truly their providence the largest, most diverse and exciting saltwater wilderness on earth. Located 440 miles south of the capital city of Mahé, Providence is a large uninhabited complex consisting of two islands (North Island and Cerf Island), and a vast array of flats in-between that has received less than 1,000 total visitors in its recorded history. ![]() Providence is a specific atoll within the Seychelles archipelago located in the Indian ocean east of Tanzania and north of Madagascar. For those that are serious about finding the most pristine and rewarding flats fishing in the world today, all points lead to here. Providence, after all, is one’s fate, destiny or divine predestination. For the most committed and adventuresome saltwater anglers, it is appropriate and even fortunate that the wildest and most productive ecosystem in the Seychelles, and likely the world, is named Providence. |
