Synthesis and antibacterial activities of some Substituted 2-styrylquinolines Quinoline nucleus is present in many biologically active classes of compounds. Some of them are used as antiprotozoic, antibacterial and antifungal drugs [1]. Among the various classes of quinolines, 2-styryl quinolines form an important group having a wide spectrum of biological activities [2 – 8] including HIV integrase inhibition activity [9 - 15]. The general method for the synthesis of these derivatives is via…

South Africa is surrounded by three major oceans namely the Atlantic, the Indian and the Southern Ocean. The west and east coast of South Africa are geographically and oceanographically distinct, supporting a wide variety of marine life. The west coast of South Africa is characterised by the relatively cold, slow-moving Benguela Current. The marine life along the west coast is adapted to colder temperatures. The waters of the west coast are nutrient-rich and support a large abundance of fish.…

Global Weirdness is a relatively easy read that is focused on the effects of global warming. The title “global weirdness” is incredibly appropriate for it is not just about global warming, but also the other “weird” factors that are occur as well; for instance, relentless droughts, rising seas, severe storms, deadly heat waves, and water movements are just a few to name. The book is consisted of four parts with sixty, short chapters and an epilogue. The first part is entitled “What the science…

clear parts of the ocean. Corals live closely together in groups expressing their bright colors that stand out so nicely. Many people consider coral reefs to be very diverse and productive than anything on land. Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves to the coral already there and develops lots of coral reefs grouped together. Photosynthetic algae called zooxanthellae live in the…

Introduction Affinity Chromatography, also referred to as biospecific chromatography, is a technique of partitioning rooted in biological affinity (Dean). This practice capitalizes on complex interactions such as bond formation between enzymes and substrate, or more broadly: macromolecules and ligands. Purification is at the center of the use of affinity chromatography. In general, samples may be run through a gel that contains a corresponding component that binds with the sample at certain…

Stone was a major building material for temples, bowls, statues and sculptures. In many cases, Egyptians chose to cover the art pieces made of stone in a layer of paint, which was made from pigments. Those pigments consisted of minerals like calcium carbonate and azurite found in the Nile and the surrounding desert. A range of colors from white to yellow to black were available to the artists. However, the colors scheme of the river, blue and green, were the predominant shades in some of the…

The Basso, Beattie, and Bresnahan (BBB) locomotor scale The Basso, Beattie, and Bresnahan (BBB) scale (numbering 0–21) is a point scale used in the analyzation of the activity of the limb joints of animals. Its locomotion rate is based on various aspects of the hind limb function like the weight support and toe clearance, just to mention a few [37]. All results were obtained at time points of 2 weeks to 8 weeks post-operation along with the blinded examination that was executed by two scorers.…

the contamination of many substances present in the water. It can be determined by various menthods ,one of which include the use of simple dil.HCL titrations in the presence of phenolphthalein and methylorange indicators. Presence of hydroxyl and carbonate ions in the boiled water results in…

Carbohydrates have the following basic composition. They are molecular compounds made from three elements: carbon, hydrogen and oxygen. Monosaccharides are simple sugars with multiple OH groups. Based on number of carbons 3, 4, 5, 6, a monosaccharide is a triose, tetrose, pentose or hexose respectively. Disaccharides are condensation products of two monosaccharide units; examples are maltose and sucrose. A disaccharide is 2 monosaccharides covalently linked molecule. Polysaccharides are polymers…
