Explain what is meant by the term "stoichiometry" in chemistry.答案:Stoichiometry is the calculation of the relative quantities of reactants and products in a chemical reaction.It is based on the law of conservation of mass and involvesthe use of balanced chemical equations and the molar massesof substances to determine the amounts of reactants needed to produce a certain amount of product or the amounts ofproducts formed from a given amount of reactant.2. Describe the difference between a physical change and a chemical change.答案:A physical change is a change in the state or form of a substance without altering its chemical composition. Examples include melting, freezing, and boiling. A chemical change, on the other hand, involves a change in the chemical composition of a substance, resulting in the formation of new substances. Examples include combustion and rusting.3. What are the three main types of chemical bonds, and givean example of each.答案:The three main types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds. An ionic bond is formed when electrons are transferred from one atom to another, resulting in the formation of oppositely charged ions. An example is the bond between sodium (Na) and chloride (Cl) in table salt (NaCl). A covalent bond is formed when two atoms share electrons, as seen in water (H2O) where hydrogen atoms share electrons with oxygen. Metallic bonds occur in metals, where a "sea" of delocalized electrons is shared among positively charged metal ions, as in sodium metal。

As in other NXCAM camcorders, the internal recording format is AVCHD 2.0. One memory card slot accepts either compatible memory sticks or SD Cards (see specs below). The optional HXR-FMU128 flash memory recording unit permits extended recording times exceeding 12 hours at 24Mbps and 10 hours at 28Mbps. Simultaneous HD-HD recording to the memory card and FMU128 is possible. Standard definition recording using the same MPEG-2 program stream system as DVD is also available.1920x1080 50/60P full HD recording at 28MbpsThe PS mode with a 28Mbps recording bit-rate enables capturing full HD at 60P. Its full HD 1920x1080 recordings can be slowed down to 24P in post for beautiful 2.5x slow motion.E mount interchangeable lens systemE mount accepts virtually any 35mm SLR, DSLR, and 35mm Cine lenses via inexpensive lens adapters (sold separately). Since the adapters do not require size converter optics no optical degradation occurs. Users are not locked on a lens brand or mount, they are free to choose from a wide variety of lens brands and lens mount. For example, auto/ manual iris control for Canon EF lenses and image stabilization of IS lenses is available via Metabones EF to E mount adapter. Canon lens is operated via the same camera user interface used to control Sony lenses.Touch focus & Focus transition (requires E mount lens use)When the NEX-EA50M is using E mount lenses it is possible to turn on the Touch Focus function which enables pulling focus by simply touching the point on the camera’s LCD touch panel where you want the camera to focus on. On the other hand you can store and pull focus between two distinct focus points via the Focus Transition function. Transition time can programed from 0.5 seconds to 90 seconds in 0.5 second increments.Face detection (requires E mount lens use)When the Face Detection function is enabled the NEX-EA50M detects and draws boxes on the faces of individuals in the frame. The user can designate a particular face as “primary”. From there on, the camera will optimize focus and exposure on the primary face. Even if the primary subject leaves the frame; if the primary returns, the camera will require and continue tracking.Exmor APS HD CMOS sensorThe NEX-EA50M is equipped with a new Exmor APS HD CMOS sensor designed for shooting Full HD video and 16.1 megapixel high-quality still photos without artifacts common to many still camera sensors. The sensor can capture full 1920x1080 HD at up to 60 fps.High Quality Still Image captureThe NEX-EA50M incorporates necessary elements for high-quality still image capture. Its mechanical shutter enables capturing fast moving subject. The photo-trigger button functions similar to still camera; push it halfwayto set focus and exposure and then press it all the way home to take the picture. Its top handle mounted hot-shoe accepts a flash.Mirroring Memory Stick supportThe NEX-EA50M is compatible with the MS-PX series "Mirroring Memory Stick”. This new type of memory card is equipped with a unique mirroring function that more reliably backs up and secures file-based footage acquired on NXCAM camcorders. The mirroring function essentially lets users record to two distinct segments onthe memory card simultaneously, giving the shooter access to the undamaged segment if errors occur to segment.A built-in Error Correction Code (ECC) catches and corrects errors as they happen and a Data Refresh feature moves data over to the "safe" zone on the undamaged segment before the error damages the card.Sony also offers “F ile Rescue Software”, which can help recover photos and video accidentally deleted.Click here to check out more details of Memory Card File Rescue Software.Location tagging with GPS TechnologyA built-in GPS function automatically records absolute time and location information every half second of a shoot to AVCHD files.Picture Profile™Six picture profile settings for different shooting conditions are provided as default settings. Selecting a picture profile for a particular scene offers an easy way to optimize the camera to match lighting conditions or for extensive creative expression image manipulation.Specifications:Features and specifications subject to change without notice.NEX-EA50M product image (with supplied lens SELP18105G attached)Please contact your local Account Manager for further information.Good Selling!Taka Kagawa Jeanne LewisProduct Manager, Pro Video Marketing Manager, Pro Video Professional Solutions of America Professional Solutions of America Sony Electronics, Inc.

The solution is stored in a brown titration glass bottle.1.2):- 10 mL of sodium periodate solution are pipetted into a 250mL flask and filled up with water.- 500 mg of glycerin are dissolved in 50 mL water and 50 mL of the diluted periodate solution was added. Wait for 30 min.- Blank: 50 mL of the diluted periodate solution was added to 50 mL water. Wait for 30 min.- 20 mL aliquots of both solutions were acidified with 1 mL of 1.0 mol/L HCl. 10 ml 0.6 mol/L KI-solution are added. Deion.water was added to achieve a volume of 50 mL. The released iodine was titrated with 0.1 mol/L sodium thiosulfate.2): 500 mg glycerin are weighed in a titration beaker and 50 mL deion. water were added. For a blank determination 50 mL deionized water were added separately into a titration beaker. The pH was adjusted to 7.8 for both solutions. 50 mL of the sodium periodate solution was pipetted into each beaker and covered wih a watch glass. Both solutions were allowed to stand for 30 min at room temperature. 10 mL of a PEG (polyethyleneglycol)/water mixture (1:1, v:v) were added to both solutions and allowed to stand for 20 min.1): According to USP26 the ratio between the volume of 0.1 mol/L sodium thiosulfate required for the glycerin containing mixture to that for the blank should be between0.750 and 0.765. The obtained ratio was 0.750. This ratio was regarded as a proof that the periodate solution is suitable for the analysis of the glycerin content.2) Acid base titration: The nominal concentration of the glycerin solution was 0.04995 mol/L (0.5061 g in 110 mL). This corresponds to a recovery of 98.90% (see results: mean value of the obtained glycerin concentration). Blank and sample determinations were performed in the same EQP-titration mode and the obtained blank value (mmol) was substracted from the sample value (mmol) in order to account for the acidity in the solvent not corresponding to the released formic acid.3) Oxidation of glycerin with periodate:CH 2OH-CHOH-CH 2OH + 2IO 4-= HCOOH + 2 HCHO + 2 IO 3-+ H 2OOne mole of glycerin corresponds therefore to one mole of formicacid.

Mazid2, Dania Ahmed11Section of Plant Pathology and Nematology, Aligarh Muslim University, Aligarh, India;*Corresponding Author:**************************2Section of Plant Physiology, Department of Botany, Aligarh Muslim University, Aligarh, IndiaReceived 16 June 2012; revised 20 July 2012; accepted 8 August 2012ABSTRACTMany species of soil-inhabiting fungus Fusa- rium, cause severe yield loss in many crops. Experiments were conducted in net house con- dition with complete randomized block design to determine the individual effect of different in- oculum levels of root-knot nematode, Meloi- dogyne incognita, Race-2 and Fusarium ox- ysporum f sp. lycopersici on plant growth pa- rameters viz., Plant length, fresh and dry weight and number of fruits of tomato var. P21. The experimental results showed that both the path- ogens cause significant reduction in plant growth parameters. However, the fungus was not much effective on plant growth parameters in com-parison to root-knot nematode. Greatest reduc-tion in plant growth parameters was recorded in plants inoculated with 8000 J2/kg soil of Meloi-dogyne incognita race 2. The threshold level of root-knot nematode was 1000 J2/kg soil while threshold level of Fusarium was @ 1 g/kg soil. Inoculum level of Fusarium oxysporum f sp. ly-copersici and Meloidogyne incognita race-2 was pathogenic and caused significant reduction at and above 1 g/kg soil and 1000 J2/kg soil re-spectively.Keywords:Fusarium oxysporum f sp. lycopersici; Meloidogyne incognita Race-2; Tomato and Threshold Level1. INTRODUCTIONTomato (Lycopersicon esculentum Mill.) is the most important tropical vegetable crop and is widely used throughout the world. It is a native of Andes region of South America. Tomato occupies second position amongst the vegetable crops in terms of production. The total production of tomato in the country in 1998-1999 was 8.27 MT from an area of 0.46 Mha. Tomato, as one of the vegetable crops and fruits, is very important in hu-man nutrition Abubakar [1]. Fruit of tomato is rich in Vitamin A, B and C Janes [2].Plant parasitic nematodes cause serious problem in various crops. Lamberti [3] reported that the root-knot nematode cause highest suppression in production of tomato ranging from 10% Taylor [4] to 80% Siddiqi [5]. Four species (Meloidogyne javanica, M. incognita, M. hapla and M. arenaria) of root-knot nematodes are major pests worldwide while another seven being important on a local basis, Eisenback and Triantaphyllou [6]. Root- knot nematodes spend maximum time of their active lives within plant roots feeding on host cells, Williamson and Hussey [7]. The infective stage secondstage juvenile (J2) penetrates through the root and migrates to a site near the vascular tissue.Reduction in yield due to root-knot nematodes (Meloi- dogyne spp.) in tomato range from 28% to 68% Adesiyan et al. [8] and 40% to 46%, Bhatti and Jain [9], Reddy [10].The tomato crop is affected by several fungal patho- gens and Fusariums sp are essentially soil borne, Berkley [11], Horsfall [12]. The fungus Fusariums oxysporum f sp and lycopersici cause wilt disease in tomato crop.2. MATERIALS AND METHODSThe important pathogens viz., root-knot nematode (Meloidogyne incognita), root-rot fungus (F. oxysporum f sp. lycopersici) and an important host plant, tomato, was selected for the present study.2.1. Isolation and Incubation of FungusThe tomato plant infected by fungus Fusarium was collected from field and brought in laboratory. FusariumS. Ansari et al. / Agricultural Sciences 3 (2012) 844-847 845was isolated from roots and collar region of infected to- mato plant. Infected part was cut into pieces (5 cm each) sterilized with sodium hypochlorite (5%) solution for 2 min and rinsed 3 time with sterile water for removal of traces of sodium hypochlorite solution. Sterilized and rinsed pieces were then transferred on petriplates filled with sterilized PDA (Potato Dextrose Agar) Medium in laminar flow. After transfer on PDA it was incubated in BOD at ±26˚C for fifteen days. Fungus was inoculated on Czapek medium and identified morphologically, Bur- gess et al. [13] and Rahjoo et al. [14]. Pathogenicity test was carried out for the identification of race of Fusarium oxysporum f sp . lycopersici.2.2. Raising of Fungus Culture and Maintainof InoculumsFungus culture was raised on Richard’s liquid medium (Magnesium sulphate: 0.25 g, Potassium dihydrogen pho- sphate: 5.00 g, Potassium nitrate: 10.00 g Potato starch: 10.00 g, Sucrose: 50.00 g, Distilled water, 1000.00 ml) Riker and Riker [15] in BOD at ±26˚C for fifteen days. Inoculums were prepared by mixing 10 g mycelial mat with 100 ml of distilled water in warring blender.2.3. Isolation and Preparation of NematodeInoculumRoot-knot nematode M. incognita was isolated from the infected roots of tomato plant. Nematodes were ex- tracted by Petridish assembly method by Chawla and Prasad [16]. Monoculture of root-knot nematode, Meloi- dogyne incognita race 2 was maintained on tomato plants. Pure culture was multiplied and after processing the number of larvae per ml, suspension was counted before inoculation. The counting of nematode @ per ml of sus- pension was done with the help of especially made counting dish under the microscope. The species/race was identified by using perineal pattern determination/ differential host range test Hartman and Sasser [17] be- fore use.The experiment was conducted under net house condi-tions in the Department of Botany Aligarh Muslim Uni-versity Aligarh (AMU) India during the year 2011. Throughout the course of studies, 6 clay pots containing 1 Kg sterilized soil + river sand + farm yard manure (3:1:1) were used and arranged in randomised complete block design and five replicates of each treatment were made and an untreated plant was served as control. The plants were watered regularly. The experiment was ter- minated after 45 days and plant growth parameters were observed in terms of Plant length, fresh weight, dry weight, number of fruits and fruit weight. Data obtained were analysed statistically at P = 0.05 and P = 0.01%.3. RESULTS AND DISCUSSIONInoculums level of fungus Fusarium oxysporum f sp. Lycopersici 0.25 g and 0.50 g/kg soil showed no signifi- cant reduction in plant growth parameters viz. Plant length, fresh and dry weight, number of fruits and fruit weight. However, the plants inoculated with inoculum levels 1.0 g - 8.0 g/kg soil showed significant reduction in plant length (66.5 - 63.1 cm), fresh weight (179.1 - 174.8 gm), dry weight (33.3 - 29.3 g), number of fruits (13.7 - 10.5) and fruit weight (234.6 - 225.0) respectively. Similarly plant inoculated with 250 to 500 J 2/kg soil of Meloidogyne incognita race-2 showed no significant reduction in plant growth parameters while plants inocu- lated with 1000 - 8000 J 2 showed significant reduction in plant growth parameters viz., Plant length (63.8 - 58.8 cm), Fresh weight (178.3 - 164.4 g), dry weight (31.7 - 23.6), number of fruits (11.8 - 8.1) and fruit weight (230.3 - 216.8) as compared to control (Uninoculated) Table 1.Tabel 1.

Reproduction factor and Number of galls/root system induced by different inocu-lum levels of root-knot nematode, Meloidogyne incognita race 2 on tomato plants. T1 = 250 J 2 of root-knot nematode, Meloidogyne incognita race 2; T2 = 500 J 2; T3 = 1000 J 2; T4 = 2000 J 2; T5 = 4000 J 2; T6 = 8000 J 2.Fusarium species is most important and soil borne disease of tomato Jones et al . [18] and Smith et al . [19]. Fungal pathogen can survive in soil for several years and cause infection in plants, Walker [20] Holiday [21]. Plants treated with M. incognita race 2 showed greatest reductions in plant growth parameters in comparison to plants treated with Fusarium oxysporum f sp. lycopersici (Table 2).A significant linear relationship was found between the initial population (Pi) and the final population (Pf) of M. incognita race 2. The multiplication of root-knot nematode significantly reduced with the increase in the inoculum levels. The reproduction factor was highest (16.6%) at the minimum inoculums level 250 J 2/kg soil and lowest (2.6%) at the maximum inoculum level 8000 J 2/plant. Thus, the rate of nematode multiplication showeda declining trend with the increase in the initial inoculum level suggesting it to be a density depending phenome-non (Figure 1). Higher multiplication rate for low initial population and low multiplication rate in high initial population was observed. Same results were also ob-served by Brker et al. [22], Di Vito and Ekanayake [23] and Haseeb et al . [24]. It can be concluded from these results that the damaging threshold levels of M. incognita race 2 on tomato was found to be as 1000 J 2/kg soil while threshold level of fungus, Fusarium oxysporum f sp. Ly- copersici, was 1 g/kg soli (Table 1 and Figure 1) .REFERENCES[1] Abubakar, U. (1999) Studies on the nematodes of cowpea(Vigna unguiculata ) of the savannah region of northernS.

Apr 17, 1995 LAB MANUAL 1303.0 1303 LIQUID LIMIT DETERMINATIONAASHTO Designation T 891303.1DEFINITIONThe Liquid Limit of a soil is that water content, as determined in accordancewith the following procedure, at which the soil passes from a plastic to aliquid state.1303.2APPARATUSA. Evaporating Dish - A porcelain dish (preferably unglazed) about115mm (4 1/2 inches) in diameter.B. Spatula - A spatula having a blade about 75mm (3 inches) in lengthand about 20mm (3/4 inches) in width.C. Liquid Limit Device - A mechanical device consisting of a brass dishand carriage as described and shown in AASHTO T 89.D. Grooving Tool - A combined grooving tool and gauge conforming tothe dimensions as shown in AASHTO T 89.E. Containers - Suitable containers with lids which will prevent loss ofmoisture prior to and during weighing. Containers should befabricated from corrosion-resistant material. One container isneeded for each moisture content determination.F. Balance - A balance conforming to the requirements of AASHTO M231, Class C, with a readability, sensitivity of 0.01 grams and anaccuracy of 0.02 grams.G. Oven - A thermostatically-controlled, drying oven capable ofmaintaining a temperature of 110 ± 5 °C (230 ± 9 °F) for dryingmoisture samples.1303.3Adjustment of the Mechanical DeviceA. Inspection1. Check the liquid limit device to determine that it is in goodworking order.2. The pin connecting the cup shall not be worn sufficiently topermit side play.Apr 17, 1995 LAB MANUAL 1303.3A3. The screws connecting the cup to the hanger arm shall betight.4. A cup that has been grooved from use shall be replaced.5. The grooving tool shall be inspected to determine that criticaldimensions conform to AASHTO T 89.B. Adjustments1. By means of the gauge on the handle of the grooving tool, andthe adjustment plate on the liquid limit device, the height towhich the cup is lifted shall be adjusted so that the point onthe cup which comes in contact with the base is exactly 10mm± 2µm above the base.2. Determine the point on the cup which comes in contact withthe base.a. For new cups, place a piece of carbon paper on thebase. Allowing the cup to drop several times will markthe contact spot.b. For used cups, a slightly worn spot will be present.3. After the contact point is determined place a piece of maskingtape across the bottom of the cup. The edge of the tape, awayfrom the hanger, should bisect the contact spot on the cup andremain parallel with the axis of the cup hanger. See Section1303.10 for a diagram of the cup and a figure showing thelocation of the tape.4. Turn the crank until the cup is raised to its maximum height.Slide the gauge under the cup from the front. Observewhether the gauge contacts the cup or the tape. If the tapeedge and the cup are both contacted the height isapproximately correct. If not, adjust the cup untilsimultaneous contact is made.5. The adjustment plate shall then be secured by tightening thescrews. With the gauge still in place the adjustment shall bechecked by revolving the crank several times. If theadjustment is correct a slight ringing or clicking sound will beheard when the cam strikes the cam follower. If the cup israised off the gauge or no sound is heard further adjustmentsshall be made.Apr 17, 1995 LAB MANUAL 1303.3B6. Always remove the tape after completion of the adjustments. 1303.4PROCEDURE - STANDARD METHOD (AASHTO T 89, Method A)(Refer to Section 1301)A. A soil sample of about 100 grams of material passing the 425µm(#40) sieve shall be placed in the evaporating dish and thoroughlymixed with distilled or demineralized water by alternately andrepeatedly, stirring, kneading and chopping with a spatula. Furtheradditions of water shall be made in small (1-3ml) increments. Witheach increment, the water shall be thoroughly mixed with the soilbefore another increment of water is added. Take approximately a10 gram sample from the mixed soil and lay aside to season for usein the plastic limit test. (See Section 1304.)NOTE 1: Once testing has begun NO additional dry soil shall be added to the moistened soil. If too much water hasbeen added, the sample shall be discarded, or the sample shall be mixed and kneaded until natural evaporationlowers the closure point into an acceptable range.NOTE 2: Some soils absorb water more slowly than others so that it is possible to add the water so fast that a falseliquid limit value is obtained. This can be avoided if the sample is mixed thoroughly or more time is allowed.B. When sufficient water has been mixed with the soil to form a uniformmass of stiff consistency, a sufficient quantity of this mixture is placedin the liquid cup and spread out by use of the spatula. The soil shallbe leveled with the spatula and trimmed to a depth of 100µm at thepoint of its maximum thickness.C. The soil in the cup shall be divided by a firm stroke of the groovingtool along the diameter through the centerline of the cam follower sothat a clean sharp groove of the proper dimensions will be formed.To avoid tearing of the sides of the groove or slipping of the soil cakeon the cup, 6 strokes maximum from front to back or back to frontshall be permitted. The depth of the groove should be increased witheach stroke and only the last stroke should scrape the bottom of thecup.D. The cup containing the sample shall be lifted and dropped by turningthe crank at the rate of two revolutions per second until the two sidesof the sample come in contact at the bottom of the groove along adistance of about 12mm (1/2 inch). Do not hold the base of themachine while turning the crank. Record the number of blowsrequired to close the groove. (A motorized device is acceptableprovided it produces the same liquid limit values.)NOTE 3: Frequently check the liquid limit device's adjustment and tighten thescrews connecting the brass cup to the hanger arm.March 1, 2023 LAB MANUAL 1303.4EE. A slice of soil approximately the width of the spatula extending fromedge to edge of the soil cake at right angles to the groove, includingthat portion of the groove in which the soil flowed together, shall beremoved and placed in a suitable container.F. The container and soil shall be weighed and the weight recorded.The soil in the container shall be oven-dried to a constant weight at110 ± 5 °C (230 ± 9 °F) and weighed. This weight shall be recordedand the loss in weight due to drying shall be recorded as the weightof water. (1303 Figure 1)G. Transfer the remaining soil in the cup to the evaporating dish. Washand dry the cup and grooving tool in preparation for the next trial.H. The foregoing operations shall be repeated for at least two additionalportions of the sample to which sufficient water has been added tobring the soil to a more fluid condition. The object of this procedureis to obtain samples of such consistency that at least onedetermination will be made in each of the following ranges: 25-35blows, 20-30 blows and 15-25 blows so the range in the threedeterminations is at least 10 blows. (EXAMPLE: 28-23-18 blows.)Ideally, a spread greater than 10 blows is desired in thedeterminations.March 1 , 2023 LAB MANUAL 1303.61303.6CALCULATIONS for STANDARD METHOD (Three points)A. The water content of the soil shall be expressed as the moisturecontent in percentage of the weight of the oven-dried soil andcalculated as follows:Weight of Water% Moisture =X 100Weight of Oven-dried SoilAs in the example (Can #1):3.02% Moisture =X 100 = 28.90.44NOTE 5: See Form #2485 (Section 1303.8)B. A "flow curve" representing the relation between moisture contentand corresponding number of blows shall be plotted on a semilogarithmic graph. The flow curve shall be a straight line drawn asnearly as possible through the three or more plotted points. SeeForm #2485 (Section 1303.8)C. Liquid Limit - The moisture content corresponding to the intersectionof the flow curve at 25 blows shall be taken as the liquid limit of thesoil. Report this value to the nearest whole number.Apr 17, 1995 LAB MANUAL 1303.8 1303.8 EXAMPLE - FORM # 2485Apr 17, 1995 LAB MANUAL 1303.9 1303.9EXAMPLE - CHART TABLES for ALTERNATE METHODApr 17, 1995 LAB MANUAL 1303.10 1303.10LIQUID LIMIT DEVICE。
