Cattle suffering with plastic foreign body syndrome were treated surgically by rumenotomy. The pre-operative and 12 th day post operative blood and serum biochemical were recorded and compared with normal healthy cattle. Preoperatively decrease in haemoglobin, packed cell volume and total erythrocyte count was observed which was gradually increased and came to near normal state on 12 th post-operative day. There was leucocytosis, neutrophilia and corresponding lymphopenia observed in animals during pre-operative phase. The glucose, serum creatinine, serum albumin and calcium levels were found to be at lower level and total proteins, blood urea nitrogen and phosphorus at higher level in pre-operative period when compared to normal cattle. This may be due to low intake of food and water and also inflammatory condition in body due to presence of plastic foreign body.
Optimization the production of extracellular lipase in culture of Bacillus cereus has been investigated. From 10 samples of diesel fuel polluted soil it was found that 3 samples was positive for the presence of B. cereus. Lipase production by B. cereus isolated from diesel fuel polluted soil was investigated and optimized. The enzyme production was increased with increasing time and maximum enzyme activity was obtained after 72 hrs of incubation. Effect of pH and temperature indicated that, the lipase production was maximum at pH 8.0 (60.2 U/ml) and at 35°C (55.25 U/ml). The lipase production was optimized in shake flask experiments. With a selected carbon sources, maltose (65.5 U/mL) and nitrogen source, peptone (66.25 U/mL) was suitable substrates for accelerating lipase production. The present study indicates that the various factors influenced enzyme production by the bacteria, it appears that the nature of the supplements had significantly influenced on the produc

Use of greenhouse cultures accompanied by new techniques such as soilless or hydroponic culture on the one hand improves suitable control of plants nutrition and on the other hand it has created a great progress in greenhouse productions. In order to greenhouse tomato cultivar of Hamra was cultured in a hydroponic system and effect of micronutrients different levels was studied on it. The experiment design was as randomized complete block with five treatments and four replications. Experimental treatments were included: Lack of micronutrients application, Full application of sulfate manganese (4.06 mg/lit), Full application of sulfate zinc (4.42 mg/lit), 50% sulfate manganese (2.03 mg/lit) + 50% sulfate zinc (2.21 mg/lit) and Full application of sulfate manganese + Full application of sulfate zinc. The results showed that the highest fresh fruit yield, fruit dry matter percentage and content of Mn and Zn in fruit obtained from full application Mn, Zn and Mn + Zn. However micronutrients different levels had significantly effect on content of nitrogen, but they haven’t significantly effect on fruit size of tomato. Key words: Micronutrients, Tomato, Hydroponic culture, Yield.
pH Management of Hydroponics Solutions A question often asked is what is the best pH for a particular crop nutrient solution. The answers given in many texts, and often by advisers to growers, are frequently based on misunderstood information. Many refer to the availability of nutrients to plants at different pHʼs based on research by Troug (1946) [Proc. Soil Sci. Soc. Am., 11:305-308] even using graphic illustrations of his ﬁndings in one form or another, generally showing a bar graph with wide portions in the pH area where the element is most widely available to the plant. I have seen similar representations said to show the availability of trace elements in a hydroponics solution. This graphic representation of availability of trace, and sometimes the major elements, only applies to plants being grown in mineral (clay based) soils. It is not relevant to hydroponics solutions.As plants use nutrients their roots release bicarbonate that raises the pH of nutrient solutions. By the early 1990ʼs I had observed that the published and advised pH at which crops were grown did not correspond to my observations. At the time phosphoric acid was being used to routinely acidify hydroponics solutions and was causing imbalances in nutrient solutions and blockages due to precipitates. It made sense to replace the phosphoric acid entirely with nitric acid which could, by monitoring pH, be added at a rate related to plant use replacing Nitrogen (N) used in growth periods and so maintain a better balanced solution free of unwanted precipitates.
Nitrogen is the most predominantly consumed nutrient among all the macro and micro elements required for plant growth. Nitrogenous fertilizers can be provided by soil application, fertigation or foliar application. In foliar process, concentration of nitrogen varies from 100ppm to 250ppm according to the needs of the plant.

Detonation (also called "spark knock") is an erratic form of combustion that can cause head gasket failure as well as other engine damage. Detonation occurs when excessive heat and pressure in the combustion chamber cause the air/fuel mixture to auto-ignite. This produces multiple flame fronts within the combustion chamber instead of a single flame kernel. When these multiple flames collide, they do so with explosive force that produces a sudden rise in cylinder pressure accompanied by a sharp metallic pinging or knocking noise. The hammer-like shock waves created by detonation subject the head gasket, piston, rings, spark plug and rod bearings to severe overloading. Mild or occasional detonation can occur in almost any engine and usually causes no harm. But prolonged or heavy detonation can be very damaging. So if you hear knocking or pinging when accelerating or lugging your engine, you probably have a detonation problem. 1. Try a higher octane fuel. The octane rating of a given grade of gasoline is a measure of its detonation resistance. The higher the octane number, the better able the fuel is to resist detonation. Most engines in good condition will run fine on regular grade 87 octane fuel. But engines with high compression ratios (over 9:1), turbochargers, superchargers, or with accumulated carbon deposits in the combustion chamber may require 89 or higher octane fuel. How a vehicle is used can also affect its octane requirements. If a vehicle is used for towing or some other application where the engine is forced to work hard under load, a higher octane fuel may be necessary to prevent detonation. If switching to a higher octane fuel fails to eliminate a persistent detonation problem, it probably means something else is amiss. Anything that increases normal combustion temperatures or pressures, leans out the air/fuel mixture, or causes the engine to run hotter than normal can cause detonation. 2. Check for loss of EGR. The Exhaust Gas Recirculation (EGR) system is one of the engine's primary emission controls. Its purpose is to reduce oxides of nitrogen (NOX) pollution in the exhaust. It does this by "leaking" (recirculating) small amounts of exhaust into the intake manifold through the EGR valve. Though the gases are hot, they actually have a cooling effect on combustion temperatures by diluting the air/fuel mixture slightly. Lowering the combustion temperature reduces the formation of NOX as well as the octane requirements of the engine.
