ANTIPROLIFERATIVE ACTIVITY OF PHYTOCHEMICALS PRESENT IN AERIAL PARTS AQUEOUS EXTRACT OF AMPELOCISSUS LATIFOLIA (ROXB.) PLANCH. ON APICAL MERISTEM CELLS

This study aimed to explore antiproliferative activity of aerial parts aqueous extract of Ampelocissus latifolia (Roxb.) Planch. (AAEAL). Antiproliferative activity of AAEAL was tested in root and/or shoot apical meristems of green gram and onion by analysing growth retardation and /or by scoring mitotic index, mitotic cell phase frequency. Phytochemical contents of AAEAL were detected and the total phenolic, tannin and flavonoid contents were estimated using standard protocols. The results indicate AAEAL treatment could induce significant growth retardation in apical meristems. In onion root tip cells, 74 % mitotic index reduction was observed with 2 mg/ml of AAEAL treatment for 12 h. Tannins, terpenoids, saponins, flavonoids, carbohydrates and anthraquiones were relatively of higher quantities and a trace amount of alkaloids and glycosides were detected from AAEAL. Tannic acid equivalents were determined from AAEAL as 21.03±0.9, 9.54±0.7 and 12.1±0.9 % respectively for total phenols, non tannin phenols and tannins while 11.7±0.5 % flavonoids were estimated as quercetin equivalents in AAEAL. In summary, the AAEAL possesses the significant antiproliferative potentials which may be due to its bioactive polyphenolics.
Initial experiments in the migration enhanced afterglow growth of gallium and indium nitride

Some initial results are presented for gallium nitride and indium nitride thin films grown on c-plane sapphire using a prototype migration enhanced afterglow (MEAglow) system. Smooth surfaces of less than 1 nm root mean square surface roughness have been achieved for both InN and GaN films at growth temperatures of 450-560 °C and 665 °C respectively. This result is attributed to the increased adatom diffusion length allowed for the metal species during the growth process. Thicker GaN layers can now be grown than those previously reported. For InN, an impressive full width half maximum value of 290 arcsec has been achieved for the (0002) reflection using ω−2θ X-ray diffraction scans. Greater progress has so far been achieved for the growth of InN films because of the relative ease with which thick layers of indium metal can be nitrided to form a good quality layer.

Qualitative Evaluation of Mixed Fruit Based Ready to Serve (RTS) Beverage

The ready to serve (RTS) beverage was prepared by blending the orange and carrot juice in the ratios of O40:C60, O50:C50 and O60:C40and stored at room temperature and refrigeration up to 45 days. The quality parameters pH, TSS, acidity and overall acceptability (OAA) were also evaluated at an internal of 15 days. The TSS and acidity of RTS beverage increased and pH was decreased with increase in the level of carrot juice ratio under different storage conditions. The higher score of overall acceptability was 8.05 for fresh sample of O60:C40 and the minimumwas 7.90 for ratio ofO50:C50 sampleat room temperature. However, the overall acceptability of RTS decreased with increase in storage period. Results of study concluded that RTS beverage was found superior under refrigeration condition as compared to room temperature
Synthesis, Crystal Structure and Antibacterial Activity of (E)-N- (2,3,4-Trimethoxy-6-methylbenzylidene)-4-methylbenzenamine

The title compound (E)-N-(2,3,4-trimethoxy-6-methylbenzylidene)-4-methyl- benzenamine (C18H21NO3, Mr = 299.36) was synthesized and characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/c, with a = 7.7239(9), b = 27.287(2), c = 8.4128(11) A,β= 111.529(2) o , V = 1649.4(3) A 3 , Z = 4, Dc = 1.206 g/cm 3 , λ= 0.71073 A, μ(Mo Kα) = 0.082 mm -1 , F(000) = 640. The final refinement gave R = 0.0525, wR(F 2 )= 0.1130 for 2899 observed reflections with I > 2σ(I). X-ray diffraction analysis reveals that the dihedral angle between the two phenyl rings is 137.8 (2) o . The molecule adopts a trans configuration about the central C=N functional bond. The crystal structure is stabilized by an intermolecular hydrogen bonding and weak π-π interactions. The title compound possesses moderate antibacterial activity.
EFFECTS OF MANURE REMOVAL STRATEGIES ON ODOR AND GAS EMISSION FROM SWINE FINISHING

Odor, ammonia (NH3) and hydrogen sulfide (H2S) concentrations and emission rates were measured in two small rooms of finishing pigs with different manure removal strategies. The strategies included daily flush, and static pits with 7-, 14-, and 42-d storage times with and without pit recharge. Tests were conducted with three successive groups of 25 pigs per room. Pigs were fed standard corn-soybean diets. Ammonia and H2S concentrations were automatically measured 15 to 24 times per day. Odor samples were collected and evaluated for odor concentration, intensity and hedonic tone by an odor panel, whose performance was verified with a reference odorant. Geometric mean odor emission rates were 19, 33, and 29 OUE s-1 AU-1 (OUE = European odor unit equivalent to 123 µg n-butanol, AU = 500 kg live mass) for 1-d (daily flush), 7-d, and 14-d manure storage times without pit recharge, respectively, and 2.6 and 25 OUE s-1 AU-1 for 7- and 42-d manure storage times with pit recharge, respectively. Mean NH3 emission rates were 14, 23, and 22 g d-1 AU-1 for 1-, 7- and 14-d manure storage times without pit recharge and 5.7, 6.8 and 7.2 g d-1 AU-1 for 7-, 14-, and 42-d manure storage times with pit recharge, respectively. Mean H2S emission rates were 0.11, 0.23 and 0.37 g d-1 AU-1 for 1-, 7- and 14-d manure storage times without pit recharge and 0.08, 0.19 and 0.91 g d-1 AU-1 for 7-, 14-, and 42-d manure storage times with pit recharge, respectively. The H2S emission rate for the 1-d storage was 0.41g d-1 AU-1 as compared with 0.11 g d-1 AU-1 when including burst emissions during flushing. Sudden emissions during flushing are not expected to influence mean emissions as much in a typical finishing building. The highest mean emission rates were equivalent to 44 and 1,146 kg yr-1 for H2S and NH3 from a 1,000-head finishing house, respectively. The data showed that lower emission rates occur when pits are recharged after emptying, and when pits are emptied more frequently.
Regionally-selective adhesion and growth of human osteoblast-like MG 63 cells on micropatterned fullerene C 60 layers

Fullerenes C 60 were deposited on to microscopic glass coverslips using the Leybold Univex-300 vacuum system through metallic masks with rectangle openings. Below the openings, the C 60 formed prominences 128 ± 8 nm (A), 238 ± 3 nm (B), 326 ± 5 nm (C) or 1043 ± 57 nm (D) in height. Human osteoblast-like MG 63 cells in the cultures on samples A, B and C were distributed almost homogeneously, while on samples D, they were localized almost exclusively in the grooves among the prominences. Thus, fullerene C 60 films can act as substrates for guided cell adhesion and growth.
Comparative Sorption of Phenanthrene and Benzo[α]pyrene to Soil Humic Acids

Sorption of phenanthrene (Phen) and benzo[α]pyrene (BaP) by humic acids (HAs) extracted from four typical soils in China, including cinnamon soil, fluvo-aquic soil, red soil, and mountain meadow soil were investigated. All sorption data were fitted well by the Freundlich model, but BaP exhibited stronger and more nonlinear sorption than Phen by a given HA. For Phen isotherms, there was a positive relation between K oc values and aliphaticity of HAs, whereas a negative correlation was observed between n values and aliphaticity. This indicated the importance of aliphatic groups in Phen sorption capacity and nonlinearity. Compared to Phen, a similar trend was obtained between n values of BaP and aliphaticity or aromatic carbon. However, no correlation existed between K oc values for BaP and aliphaticity or aromatic carbon.
Heavy metals concentration in tannery effluents, associated surface water and soil at Ejersa area of East Shoa, Ethiopia

Accepted March 9, 2014 Discharges from tanneries are the major causes of environmental contamination in Ethiopia. A field experiment was carried out during 2012-2013 to assess the contamination of surface water and soil by heavy metals. Surface water samples were collected from Ethiopia Tannery from five different sampling areas (from the tannery outlet up to Koka Lake) by dividing in four equal distances S1 – S2 (0-0.75 km, upstream), S 2 – S3 (0.75 – 1.50 km), S 3 – S4 (1.50 –2.25 km) and S4 – S5 (2.25 –3.0 km, downstream(at the entry point of Koka Lake)). Soil samples were also collected from the proximate of the effluent samples collected at the depth of 0-10 cm and 10-20 cm. The control soil samples (S 0) were collected from the farm land which is placed out of the effluent point). The concentration of heavy metals was determined using graphite furnace atomic absorption spectrometer and atomic absorption spectrophotometer The parameters determined were (pH, Electrical Conductivity (EC), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) and for heavy metals namely: Cd, Cr, Cu, Fe, Pb, and Zn. The results on surface water quality showed that metals such as Cr, Fe and Pb exceeded the standard levels as stated in the guideline for irrigation water, while the concentrations of Cd, Cu and Zn were found to be less than the standard level of concentration as stated in the guideline for irrigation water. From this result, the surface soil in the study area from the tannery effluent outlet to the nearest sampling sites of Lake Koka 2.25-3.0 km has no heavy metals contamination from the standard threshold value point of view, except the 0-2.25 km sampling sites.
Shock‐tube study of carbon monoxide dissociation kinetics

The dissociation kinetics of undiluted carbon monoxide have been investigated over the temperature range 5600–12 000°K. Data were obtained as time‐resolved pressure measurements on the end wall of a shock tube and radiation emission histories of the C2 Swan system (0–0 band) behind incident shock waves. The dissociation rate for the over‐all process CO+M→ lim kd ,MC+O+M was found to be kd,M=8.0×1038 T−5.5 exp(−1.29×105/T) cm3/mole·sec, independent of the proportions of the collision partners M=CO, C, and O. The above rate constant is about 10 times that previously measured with argon as a collision partner and is in close agreement with the measurements of kd,M(M=CO, C, O) by Chackerian and of kd,O by Appleton, Steinberg, and Liquornik.
Crystal structure of layered perovskite compound, Li2LaTa2O6N

The initial structural model was successfully derived by the direct methods and further refined by the Rietveld method, with the anisotropic atomic displacement parameters being assigned for all atoms. The final reliability indices were Rwp=5.73%, S=1.46, Rp=4.33%, RB=1.13%, and RF=0.53%. Li2LaTa2O6N has a layered perovskite structure similar to that of Li2LaTa2O7.
Impact of pregnancy on the concentrations of selected phthalates

Developing fetus can be exposed to toxicants during pregnancy. Impact of human pregnancy on the concentrations of phthalate metabolites mono(carboxynonyl) (MCNP), mono(carboxyoctyl) (MCOP), mono-2-ethyl-5-carboxypentyl, mono-n-butyl, mono-(3-carboxy propyl), monoethyl, mono-2-ethyl-5-hydroxyhexyl, mono-2-ethylhexyl, monoisobutyl, mono-2-ethyl-5-oxohexyl phthalate, mono-benzyl, sum of low molecular weight phthalates (∑LMW), sum of high molecular weight phthalates (∑HMW), and sum of diethylhexyl phthalates was assessed. Data from the National Health and Nutrition Examination Survey for the years 2005–2010 were used for this purpose. Regression models with logs of these metabolites as dependent variables and age, race/ethnicity, education, pregnancy, smoking and iron storage status, study year, family poverty income ratio (PIR), body mass index, urine albumin, and urine creatinine as independent variables were fitted. Pregnant females were found to have significantly lower concentrations of ∑HMW and MCNP than non-pregnant females. Concentrations of ∑LMW during the third trimester of pregnancy were significantly lower than during the second trimester of pregnancy.
Hepatoprotective activity of aloe vera gel against paracetamol induced hepatotoxicity in albino rats

Objectives: To study the hepatoprotective activity of aqueous extract of Aloe vera in paracetamol induced hepatotoxicity inalbino rats.Methods: Hepatotoxicity was induced with a single dose of paracetamol 3g/kg orally. The curative and regenerative effect ofAloe vera on paracetamol induced hepatotoxicitywas studied. N acetyl cysteine was used as standard treatment forhepatotoxicity in this study.The animals were divided into eight groups(n=6). First four groups received either vehicle (2% gumacacia),Aloe vera (250 mg/kg or 500 mg/kg ) or N- acetylcysteine ( 450mg/kg) single dose orally with paracetamol3g/kg orally.The next four groups of animals received the same treatment for 7 days along with single dose of paracetamol 3g/kg orally.After the treatment period the blood samples were collected from orbital sinus and aspartate transaminase (AST), alaninetransaminase (ALT) and alkaline phosphatase (ALP) were estimated.Liver homogenates were used for estimation of tissue thiollevels. Results: Paracetamol in the dose of 3g/kg significantly elevated AST , ALT and ALP and depleted the liver thiol levels whencompared with vehicle treated group. Single day treatment with the aqueous extract of Aloe vera in the dose of 250 and500mg/kg reduced the AST, and ALT levels significantly (p<0.01). 500mg /kg of the extract also reduced the ALP levels andrestored the depleted liver thiol levels significantly (p<0.01), however there was no effect on alkaline phosphatase and liverthiols by Aloe vera in the dose of 250mg/kg.Seven day treatment with both the doses of Aloe vera significantly reduced thelevels of AST, ALT and ALP significantly (p<0.01) and restored the depleted liver thiol levels significantly (p<0.01). Surprisingly, N-acetylcysteine the drug used to treat paracetamol toxicity on single or seven day treatment reduced only AST and ALT levelswith no effect on ALP and liver thiols. Conclusion: This study shows that the aqueous extract of Aloe vera has hepatoprotective activity
Exploring the Capability of Multifrequency Charge Pumping in Resolving Location and Energy Levels of Traps Within Dielectric

Multifrequency charge-pumping (MFCP) experi- ments have recently been used by many groups to profile the locations and the energy levels of bulk traps within high-κ gate dielectric stack of MOS transistors. Since the measurements in- volve easy generalization of the classical CP technique, the inter- pretation of the data has sometimes been based on uncritical generalization of classical CP theory or a simplified numerical model that does not capture the complexity and nuances of the dynamics of occupation of dielectric traps. In this paper, we develop a rigorous numerical model of MFCP technique and encapsulate/interpret the results using an intuitively simple ana- lytical formula. Consistent with some earlier reports, we observe that MFCP experiment scans a limited region of traps within the dielectric stack. Although the degree of trap response in MFCP is a (nonintuitive) function of parameters like rise/fall time, frequency, temperature, and pulse levels, we show that only a certain combination of parameters is sufficiently orthogonal to allow unambiguous back-extraction of the trap profile.
Effects of Cap and Overall Fermentation Temperature on Phenolic Extraction in Cabernet Sauvignon Fermentations

The phenolic content of red wine is responsible for the color, mouthfeel, and aging potential of the wine. Although many fermentation parameters and winemaking techniques affect phenolic extraction, it is generally agreed that one of the prime factors is fermentation temperature; however, temperature is not uniform during fermentation and thermal gradients form between the cap and the liquid. To determine the effects of temperature on phenolic extraction, research scale (120 L) Cabernet Sauvignon fermentations were performed in which the cap and must were either maintained at the same temperature or a constant thermal gradient was maintained between the two during the period of active fermentation. All fermentations were sampled twice daily and phenolic content was determined by reverse-phase high-performance liquid chromatography for the monomeric phenolics and UV-vis spectroscopy for the total anthocyanins and condensed tannins. These experiments showed that cap and must temperature had noticeable effects on phenolic extraction based on where the phenolics originated. For skin phenolics, temperature affected the rate of extraction but not the final concentration, and increasing temperatures favored faster extraction. For seed phenolics, increases in fermentation temperature increased both the rate of extraction and the final concentration. Results showed that must temperature was more important than cap temperature in driving extraction of phenolics.
Fast dynamic model family of semiconductor switches

As many users of simulation tools as many simulation objectives exist. Depending on the simulation target, users have different requirements on the model accuracy. The paper presents a semiconductor model family with user selected modelling levels. Depending on the required accuracy, model properties can be turned on or off and thus extending or shortening the computation time.

Deslocamento miscível de nitrato e fosfato proveniente de água residuária da suinocultura em colunas de solo

Fertigation with wastewater from swine is very much used, mainly in the southern region of Brazil. However, the high polluting potential of these wastewaters represents a threat of soil contamination of surface and underground waters if used in excessive amounts. The objective of this work was to evaluate the leaching process of nitrate and phosphate ions in soil columns, getting the hydrodynamic dispersion coefficient and factor of retardation and potential of contamination of underground water. The effect of wastewater application on physical and chemical properties of the soil was verified. The results showed that the potential for contamination of underground water by nitrate ions is high, in contrast to what occurs with phosphate ions that presented low potential of contamination due to their high reactivity.
Capsule-free fluid delivery and beam-induced electrodeposition in a scanning electron microscope

Gold coated borosilicate nanocapillaries are used to locally deliver aqueous, electrolytic CuSO4 solution into the low vacuum chamber of an environmental scanning electron microscope (ESEM). Capillary flow of the liquid is induced by bringing a nanocapillary into contact with a substrate. A microscopic droplet is stabilized by controlling the droplet evaporation rate with the substrate temperature and the pressure of H2O vapor injected into the vacuum chamber. An electron beam is admitted to the droplet through a pressure limiting aperture. Electrochemical reduction of aqueous Cu2+ to solid, high purity, deposited Cu is achieved by biasing the nanocapillary and supplying current by the beam which acts as a virtual cathode and enables electrodeposition on both conductive and insulating substrates. Delivery of liquids into vacuum enables localized, capsule-free beam induced electrochemistry, opening new pathways for direct-write nano and micro-lithography via beam induced electrodeposition.
Human lymphoblast mutagens in urban airborne particles

While it is known that urban airborne particles typically contain trace levels of bacterial mutagens and rodent carcinogens, little work has been done to identify chemicals in such particles that can genetically alter human cells. In this paper, we describe the analysis of an organic extract of a Washington, DC, airborne particle sample (SRM 1649) for human cell mutagens. Due to the chemical complexity of the extract, a bioassay-directed fractionation method was used to separate mutagenic constituents into chemically simplified fractions. Mutagenicity testing was done using the h1A1v2 cell line, a line of human B-lymphoblastoid cells that have been engineered to overexpress the human cytochrome P4501A1. Chemical analysis of mutagenic fractions was accomplished using GC−MS and HPLC−UV techniques. Our results indicate that ∼20% of the total mutagenicity the extract was accounted for in two fourth-order fractions that contained ∼3% of the total extract mass. These fractions were composed largely of polycycli.
Apatite‐Forming Ability of Sodium‐Containing Titania Gels in a Simulated Body Fluid

An essential condition for an artificial material to bond to living bone is the formation of bonelike apatite on its surface in the living body. The bonelike apatite can be reproduced on the bone-bonding material even in an acellular simulated body fluid (SBF) with ion concentrations almost equal to those of human blood plasma. In the present study, the dependence of the apatite-forming abilities of sodium-containing titania gels in a SBF on composition and structure is examined. The sodium-containing titania gels are model substances produced on the surface layer of bioactive titanium metal prepared by sodium hydroxide solution and heat treatments. When sodium-containing titania gels are immersed in the SBF, Na+ ions incorporated in the gels are exchanged with the H3O+ ions in the SBF. This ion exchange causes an accompanying increase in the pH of the SBF and increases its ionic activity product, thus providing favorable conditions for apatite nucleation on the surfaces of the gels. Nevertheless, sodium-containing titania gels that do not contain anatase do not form apatite on their surfaces. Independent of the composition, the gels form apatite on their surfaces in the SBF, specifically when they contain anatase. These results imply that the Ti-OH groups on titania, which have been proposed to be responsible for the apatite formation, are effective for apatite nucleation when they are arranged in a specific structural unit based on the anatase structure.
