Antarctic sea ice covers vast area of the southern ocean and is one of the most dynamics environments on the planet. The seasonal sea ice zone over which sea ice advances and retreats each year is about 30% or approximately 14 million km2 of the southern ocean, reaching its maximum extent in September- October. Sea ice is a key factor in ocean atmosphere interaction, global ocean circulation, and through the ice-albedo feedback mechanism and integral part of Earth-climate system. It is also dominant seasonal force in marine- ecosystem. Around the cost of Antarctica, sea ice may be fastened to the shore or to grounded icebergs and remain immobile as a continuous sheet.
Allosaurus means “different Lizard” a strange name for the most powerful, fearsome, and deadly dinosaur of the Late Jurassic. Allosaurus was the main enemy of the giant sauropods, including Apatosaurus and Diplodocus, even though the plant-eaters weighed much more than the two-ton predator. Until the tyrannosaurs appeared 50 million years later, Allosaurus and its relatives were the largest predators to roam the earth. During the Late Jurassic, Allosaurus was the world's No. 1 predatory dinosaur. It possessed unusually light weight spinal bones. It was a carnosaur, one of the groups of theropod meat-eaters.
Chitosan has prompted the continuous movement for the development of safe and effective drug delivery systems because of its unique physicochemical and biological characteristics. The primary hydroxyl and amine groups located on the backbone of chitosan allow for chemical modification to control its physical properties. When the hydrophobic moiety is conjugated to a chitosan molecule, the resulting amphiphile may form self-assembled nanoparticles that can encapsulate a quantity of drugs and deliver them to a specific site of action. Chemical attachment of the drug to the chitosan throughout the functional linker may produce useful prodrugs, exhibiting the appropriate biological activity at the target site. Muco-adhesive and absorption enhancement properties of chitosan increase the in vivo residence time of the dosage form in the gastrointestinal tract and improve the bioavailability of various drugs. The main objective of this review is to provide an insight into various target-specific carriers, based on chitosan and its derivatives. The first part of the review is concerned with the organ-specific delivery system using chitosan and its derivatives. The subsequent section considers the recent developments of drug delivery carriers for cancer therapy with special focus on various targeting strategies.
Fly ash is mainly generated due to combustion of coal in thermal power plant. This is a problematic solid waste all over the world. Its disposal requires high amount of water and large area for ash pond. Hence, management of fly ash would remain a great concern in recent decades. However several studies on fly ash shows that they may improve physical, chemical and biological properties of degraded soil and it also a source for micro and macronutrient. On practical point of view the values of fly ash in agriculture have been experimented as an eco-friendly and sustainable approach after its repeated field experiments to confirm its safety as well as quality. This study encompasses some areas like soil fertility, biological reclamation of waste land and growth of vegetable crops.
The haematological and biochemical parameters of some domestic fowl (Gallus gallus domesticus) of 300-500g body weight and aged between 16-20 weeks old were investigated in 10 broilers and 10 Hamburgh (red jungle fowl) breed respectively using both their whole blood and serum samples. The blood group of both breeds had (A+, B+, and O-) as those in man. The Hb genotype (HbAA, HbAS) also showed similarities to that of man. The mean and standard deviation values of the packed cell volume (PCV), white blood cell (WBC) count and platelets of the two breeds (broilers and jungle fowls) respectively are; (30.4 ± 2.8% and 30.6 ± 1.43%), (25.88×109 ± 3.4μL and 17.42×109 ± 0.6μL), (43.8×109 ± 4.6μL and 34.5×109 ± 3.80μL). Mean ± S.D values from serum for sodium, potassium, bicarbonate, chlorine, urea, creatinine, calcium, total protein and albumin were; (139.57 ± 2.40mmol/L and 137.46 ± 2.0mmol/L), (1.84 ± 0.97mmol/L and 3.39 ± 1.05mmol/L), (27.0 ± 2.45mmol/L and 25.8 ± 1.54mmol/L), (110.34 ± 11.1mmol/L and 93.96 ± 4.9mmol/L), (8.45 ± 2.07mmol/L and 5.43 ± 0.93mmol/L), (73.6 ± 12.2mmol/L and 70.54 ± 13.2mmol/L), (3.7 ± 0.73mmol/L and 4.17 ± 0.93mmol/L), (64.7 ± 13.0g/L and 68.07 ± 12.65g/L) and (30.79 ± 7.1g/L and 34.26 ± 9.60g/L) respectively. The research indicates that the haematological and serum biochemical values could serve as baseline information for comparing conditions of nutrient deficiency, physiological and health information of both the broilers and Hamburgh (red jungle fowl) breed.
Earth is under constant bombardment by space rocks. When they crash and burn through the atmosphere, most of the debris gets lost to the oceans, while some is buried or gradually weathered away. Nonetheless, plenty of chunks of fallen meteors, or meteorites, are strewn across the accessible parts of the planet. So far, more than 40,000 meteorites have been found and catalogued, and countless more are still out there, waiting to be chanced upon. If you need further incentive for finding something that was forged at the birth of our sun and contains secrets about the nature of our solar system, there's this: Space rocks are worth as much as $1,000 per gram.
In India, the rice-wheat cropping system (RWCS) fulfils 80% of the food requirement and 60% of the nutrition requirement of Indian population. Out of the total rice and wheat production in India, 42% comes from Indo-Gangetic Plains (IGP) comprising Punjab, Haryana, Uttar Pradesh, Bihar and West Bengal. The post-green revolution period, however, showed a decline in yield trend, mostly because of imbalanced use of fertilizers and pesticides, overexploitation of the natural resources, particularly water, deterioration in physical conditions of the soil and emergence of new bio-types of pests and diseases. These led to yield stagnation, causing concern about the future potential for productivity growth and long-term sustainability in the irrigated RWCS. In this paper discussed the various research needs and direction such as cropping system approach, inclusion of leguminous crops in the crop rotations or as mixed crop, balanced use of plant nutrients, integrated nutrient management, green manuring, recycling of residues, resource conservation technologies, adoption of non-monetary inputs like timely sowing, maintaining optimum plant population, timely irrigation, efficient use of fertilizers, need based plant protection measures and timely harvesting of crop to break the stagnation in the productivity of RWCS and to sustain the natural resources for the future generations.
Squalamine is an essential ingredient which may be derived from various sources in nature. One known source of squalamine is predominantly found in the liver tissue (not the "liver oil") of the deep water shark. The "liver oil" of the shark contains only trace amounts of the compound squalamine, however, it also contains many other exotic compounds. Squalamine is not a protein. Instead, it is the first known example of a class of compounds called aminosterols, each being a steroid chemically linked to an amino acid. Proteins are easily destroyed by digestive enzymes in the stomach; however, squalamine remains unscathed through the digestive tract.
