Pesticides, heavy metals and detergents are major cause of concern to aquatic environment because of their toxicity and tendency to accumulate in the organism. These concentrations may sometimes reach to the lethal levels causing mortality in fishes which is harmful for humans when consumed by them. Effect of Chlorpyrifos concentration on enzyme activities in the liver of an air berating fish, Channa punctatus (Bloch) exhibited notable alteration. The median lethal concentration (LC50) for Chlorpyrifos pesticide was analyzed statistically by log dose / probit regression line method (APHA, 1971). Acid and Alkaline phosphatase enzymes in liver was estimated quantitatively by Fisk and Subbarow (1925). The selected sub lethal concentration on the experimental protocol were 10 PPM and 20 PPM for exposure of 10, 20 and 30 days respectively Chlorpyrifos pesticides caused significantly (P

Genomic repositories increasingly include individual as well as reference sequences, which tries to share near-identical and long identical strings of nucleotides. The sequential processing used by many compression algorithms and the volumes of data involved in compression, mean that these long-range repetitions of sequences are not detected. In this paper authors have shown that a new method of dictionary construction for compression has been very effective in long-range repetition detection making it ideal for compressing very large DNA data sets. The results have shown that improved COMRAD method is able to compress much larger data sets than existing DNA compression algorithms and able to detect repetition over a much longer range than existing general-purpose dictionary-based compression algorithms. Also authors have try to shown experimentally with the help of comparison tables and line graph that the method is effective and many improvements can be made to the general idea to create a very powerful and extendible compression algorithm for compressing and searching in very large data sets.

Concrete is widely used in structural engineering with its high compressive strength, low cost and abundant raw material. But common concrete has some shortcomings, for example, low tensile and flexural strength, poor toughness, high brittleness, and so on that restrict its application. To overcome these deficiencies, additional materials are added to improve the performance of concrete. A Nano admixture is a composite material that has been developed in recent years. It has been successfully used in construction with its excellent flexural tensile strength, permeability and so on. An attempt has been made in this paper to provide the advantages and benefits of using nano admixtures in concrete for a variety of applications. The use of admixtures help in modifying properties of concrete both in plastic and hardened stage and thus results into a more durable concrete. The main purpose of this investigation is to study the effects of nano clay on the compressive, split tensile and flexural strength of concrete. Concrete specimens were casted with and without nano clay and tested after 7 and 28 days water curing. Experimental results show that addition of admixtures improves the performance of concrete.

Biodiesel is a renewable fuel that can be produced from vegetable oils, animal fats, or waste oils for use in diesel vehicles. Biodiesel\'s physical properties are similar to those of petrodiesel, but it is a cleaner-burning alternative. In this work, waste cooking oil and methanol as feedstock together with sulfuric acid and potassium hydroxide as catalysts were used to produce biodiesel. Physical properties of waste cooking oil, produced biodiesel and purchased petrodiesel were measured using specified ASTM standards. To examine their performances and emissions of their flue gases, biodiesel and petrodiesel were burnt in a wet base semi-industrial boiler. The emitted gases of combustion were measured with a flue-gas analyzer at a wide range of air to fuel ratios and two levels of energies. For better reliability, all tests were repeated five times and almost no sensible differences were found in repeat tests. The results show that biodiesel meet ASTM standards. These properties of biodiesel are also comparable with the petrodiesel properties. The trends of exhaust temperature and combustion efficiency of biodiesel are the same as petrodiesel at different air to fuel ratio. However they are slightly lower. The CO, NOx, SO2 and CO2 emissions of biodiesel are lower than those of petrodiesel at different air to fuel ratio and two levels of energies

Ankle joint is one of the most complicated anatomic/functional structures of locomotor aparatus.The upper ankle joint (talocruralis) connects lower end of shin/bone (tibia) and fibula with ankle bone (talus).It represents the connection between lower leg bones and foot bones.The upper and lower ankle joints make functional,anatomic and clinical whole,not only in physiological conditions but in most injuries.Distorsion is the most frequent type of ankle joint injury.It is actually the set of injuries of ligaments,joint capsule and attachement of muscle tendon in the motor power.The foot inversion is the most common injury mechanism,and the foot can be in supination and adduction.There have been 37 examinees obserevd.All of the them have suffered from ankle joint injury,of male and female gender,18-35 years old.The examinees with clinical and radiographic diagnosis of sprained ankle were observed in emergency room and Orthopedic clinic in Podgorica.The results of our study are surch that points the most frequent injuries at workers with distorsion of ankle joint in lateral ligament complex injury,as weel as the sprains of medium level.\nThe most common ways of being injured in doing different works has been while walking on flat surface.The exception is the injury caused by running in doing work demanding a lot of movements.

In this research, a rapid, solvent-free and single step method for the analysis of essential oil compounds in dry rosemary leaves (Rosmarinus officinalis L., Lamiaceae) using gas chromatography–mass spectrometry (GC–MS) following microwave distillation and headspace solid-phase micro extraction (MD-HS-SPME) is reported. Compared with a conventional technique, HD., the advantages of the proposed method are: a short extraction time, good precision, and high extraction efficiency. All experimental results show that the presented method is an alternative tool for the fast analysis of essential oils in dry rosemary leaves.
