ROLE OF MACROLIDES (CLARITHROMYCIN) ON
BIOFILMS IN CHRONIC RHINOSINUSITIS

Abstract Background: Rhinosinusitis, a group of disorders characterized by inammation of the nose and paranasal sinuses can be classied as acute, sub-acute or chronic and recurrent based on the duration of inammation. Biolm with formation of a physical barrier prevent antibiotics from penetrating it. Macrolides achieve high intracellular concentration and have a spectrum of activity against Gram positive cocci. This study aims to describe effect of macrolide antibiotics (clarithromycin) on eradication of suspected biolms in chronic rhinosinusitis.
Clinical Trials in Hemodynamic Support

Despite a significant number of randomized trials and meta-analyses of cardiovascular support in the preterm population, the neonatal community is still at a loss on how to approach the preterm infant with low blood pressure (BP)/low blood flow states during the first days of life. The trials to date are characterized by significant heterogeneity—in the populations studied, their inclusion criteria, and the interventions and endpoints chosen—but all are characterized by one important aspect—small numbers of enrolled patients (from 20 patients through to 90)—and all are underpowered to draw any short-term or long-term conclusions to direct clinical care. The mantra of intervening when the mean BP falls below the mean gestational age in millimeters of mercury has remained set in stone for the majority, and the primary agent used remains dopamine. Familiarity with this approach has meant that it rarely has been challenged. A desire to oversimplify and homogenize what essentially is a heterogeneous, complex, and multifaceted pathophysiologic phenomenon has meant that 40 years on there still are not any concrete answers, other than that inotropes do (generally) increase BP.

Chemical studies on rutherfordium (Rf) at JAERI

Summary Chemical studies on element 104, rutherfordium (Rf), at JAERI (Japan Atomic Energy Research Institute) are reviewed. The transactinide nuclide 261Rf has been produced in the reaction 248Cm(18O, 5n) at the JAERI tandem accelerator with the production cross section of about 13 nb. On-line anion-exchange experiments on Rf together with the lighter homologues, group-4 elements Zr and Hf, in acidic solutions have been conducted with a rapid ion-exchange separation apparatus. From the systematic study of the anion-exchange behavior of Rf, it has been found that the properties of Rf in HCl and HNO3 solutions are quite similar to those of Zr and Hf, definitely confirming that Rf is a member of the group-4 elements. However, we have observed an unexpected chemical behavior of Rf in HF solutions; the fluoride complex formation of Rf is significantly different from those of the homologues. Prospects of extending chemical studies on transactinide elements in the near future at JAERI are briefly considered.
Technological Diversification and Firm Performance: The Contingency Effects of Independent Directors and Growth Opportunity

The accumulated evidence is inconclusive concerning the performance effect of technological diversification, suggesting that further research is needed to unravel the complex relationship between technological diversification and firm performance. The purpose of this study is thus to explore the contingency factors underlying the technological diversification-performance pattern, i.e., the moderating effects of board independence and growth opportunity. This study focuses on Taiwanese publicly listed firms in high-tech industries because they are facing increasing innovation pressure. Panel data on 2,139 firm-year observations of 406 publicly listed Taiwanese high-tech firms in the period of 2008-2017 were used to test for our hypotheses. Based on the sample of Taiwanese high-tech firms, the findings show that there is an inverted U-shaped performance effect of technological diversification. Such a non-linear performance effect of technological diversification can be positively moderated by higher levels of board independence and growth opportunity.
The use of electromigration as a qualitative technique to study the migration behaviour and speciation of uranium in the Boom Clay

Summary Under the geochemical conditions prevailing in situ in the Boom Clay Formation (pH, Eh, …), calculations predict that U(OH)4 is the dominant uranium species present in the interstitial water and the concentration is solubility limited. However the boundary of the domain where the non solubility limited UO2(CO3)34− species dominates is very close. It is therefore of prime interest to know the correct speciation of uranium during the migration process. Electromigration was used as technique with the advantage that it can provide information on the speciation because the movement of the species towards the electrodes depends on its charge and speciation. Electromigration experiments have been performed with preconditioned 233UO2(CO3)34− sources, starting from the hypothesis that this species should migrate without retardation towards the anode. Despite relatively long electromigration times, sufficient to displace strong retarded tracers, no displacement of the migration profile towards the anode was observed. All 233U remained near the source position, but the electropherograms clearly showed the presence of species moving towards the cathode. This indicates the presence of neutral or positively charged uranium species. These electropherograms are interpreted as a change in uranium valence state: reduction of UO2(CO3)34− and precipitation of U(IV) oxy-hydroxides near the source position. The solubility limited species, U(OH)4(aq), are carried with the pore water towards the cathode. The electromigration experiments indicate, in support of the speciation calculations, that the dominant migrating U-species is probably the solubility limited U(OH)4.
Use of giant reed (Arundo donax L.) to control soil erosion and improve soil quality in a marginal degraded area

Soil erosion is one of the biggest environmental problems throughout European Union causing considerable soil losses. Vegetation cover provides an important soil protection against runoff and soil erosion. To this aim, unlike annual crops, perennial plants have the advantage of covering soil for a longer time and reducing soil erodibility thanks to SOM increase due to litter effect and to reduction of soil disturbance (no-tillage). Two experiments were carried out in marginal hilly areas (10% slope) of Southern Italy: i) long-term experiment in which it was evaluated the effect of two fertilization doses (N: 100 and 50 kg N ha−1 from urea) on Arundo donax L. biomass production as well as its effect on soil erosion; ii) three-year experiment to evaluate the soil cover capacity of the giant reed by analysing the plant leaf area index (LAI). Results of the two experiments showed a good soil protection of Arundo donax L. that reduced soil losses by 78% as compared to fallow and showed soil erosion reduction not different from permanent meadow thanks to the soil covering during the period with the highest rain erosivity and to the reduction in soil erodibility. The protective effect of Arundo donax L. from rain erosivity was also confirmed by LAI analysis that showed a good soil covering of giant reed in the above mentioned period, even during the initial yield increasing phase following crop transplant. According to biomass yield, from the fifteen year of cultivation in a low fertile inland hilly area of Southern Italy, giant reed was characterized by a yield-decreasing phase that resulted postponed as compared to more fertile environments thus ensuring a longstanding soil protection from soil erosion. In addition, the higher nitrogen fertilization dose (100 kg ha−1 of N) allowed interesting biomass yield as compared to the lower dose (50 kg N ha−1) and kept constant SOC along the year of experimentation due to an improved contribution of leaf fall, root exudates and root turnover
Qualidade fisiológica das sementes de sorgo sacarino submetidas à secagem em diferentes condições de ar

Objetivou-se, com este trabalho, analisar a qualidade fisiologica das sementes de sorgo sacarino submetidas a secagem em diferentes condicoes de ar. A secagem do sorgo sacarino foi realizada mantendo-se as temperaturas controladas de 40, 55, 70, 85 e 100 °C e umidades relativas de 28,4; 18,6; 12,2; 7,3 e 3,1%, durante os periodos de 3,0; 1,75; 1,42; 1,08 e 0,83 h, respectivamente. Depois da secagem as sementes foram submetidas as analises de condutividade eletrica, porcentagem de germinacao, primeira contagem da germinacao, indice de velocidade de germinacao (IVG), porcentagem de emergencia, primeira contagem da emergencia e indice de velocidade de emergencia (IVE). Constata-se que o aumento da temperatura do ar de secagem promove maior danificacao nas sementes, pelo aumento da condutividade eletrica da solucao. A porcentagem de germinacao, IVG, porcentagem de emergencia e o IVE, tiveram seus valores reduzidos pelo incremento de temperatura. Conclui-se que a qualidade fisiologica das sementes de sorgo sacarino e afetada pela temperatura do ar de secagem e que as temperaturas mais elevadas promovem maiores danos as sementes podendo ser realizada a secagem ate a temperatura do ar de 55 °C.
EARLY DETECTION OF COTTON LEAF NITROGEN STATUS USING LEAF REFLECTANCE

ABSTRACT Nondestructive assessment of cotton (Gossypium hirsutum L.) nitrogen (N) nutritional status could aid fertilizer recommendations by providing a rapid, easy, and inexpensive method of detection. A greenhouse experiment with fertilizer N rates equivalent to 40, 80, 120, and 160 kg ha−1 was conducted to determine the response in leaf reflectance and chlorophyll meter readings to varying N nutritional levels. A 50/50 blend of masonry sand and a Marietta soil (fine-loamy, siliceous, thermic Fluvaquentic Eutrochrepts) was used as potting media. Measurements were taken the second week of squaring and the second week of flowering. Reflectance and chlorophyll readings were found to be significantly (p<0.05) correlated with leaf N content. A deficiency of N increased leaf reflectance and decreased chlorophyll readings. However, prediction models based on light reflectance measurements at 550 nm wavelength (λ) provided better estimates of cotton N status at squaring (r 2=0.60, p=0.0032) and flowering stages (r 2=0.89, p=0.0001), than chlorophyll meter readings (r 2=0.36, p=0.0396, and r 2=0.87, p=0.0001, respectively). Prediction models based on red edge wavelengths improved N concentration estimates only at flowering (r 2=0.92, p=0.0001). Leaf reflectance as an indicator of leaf N status may be a feasible tool to quickly estimate the N nutritional status of cotton when N alone is the limiting nutrient.
Biosurfactant Facilitated Biodegradation of Quinalphos at High Concentrations by Pseudomonas aeruginosa Q10

Previous studies indicate that high concentration of pesticides and their associated toxic effects are high at their point source of application. Use of pesticide-degrading bacteria at point sources could augment degradation and thereby reduce toxic effects associated with pesticide persistence in soil. Quinalphos, an organophosphorus insecticide, though ranked “moderately hazardous” in the WHO's acute hazard ranking, still continues to be used extensively in developing countries. The presence of a chloride radical usually makes this pesticide sparingly soluble in water and hence difficult to degrade. The present study aimed to isolate autochthonous bacterial strains capable of utilizing quinalphos as a carbon source. Primary screening of pesticide-contaminated soil by enrichment culture and degradation analysis by UV-VIS spectrophotometry led to the isolation of 12 different bacterial isolates, of which three efficient isolates of Pseudomonas sp, Serratia sp, and Pseudomonas aeruginosa with degradation rate 86%, 82%, 94%, respectively, were selected. GC-MS studies with P.aeruginosa confirmed the formation of 2-hydroxy quinoxaline and phosphorothioic acid as a result of biodegradation. The present study succeeded in isolating autochthonous bacterial strains capable of utilizing high concentrations of quinalphos as a carbon source in a shorter incubation period. This strain also possessed biosurfactant-production ability, which makes quinalphos available to cells at higher concentrations.
Mineralization and N Fertilizer Equivalent Value of Composts as Assessed by Tall Fescue (Festuca arundinacea)

The capability to determine nitrogen availability of composts is necessary to ensure that such materials will provide sufficient fertilization to the growing crop and cause minimal environmental degradation. A greenhouse study using tall fescue as a bioindicator was used to evaluate nitrogen availability of two biosolids composts, two mixed yard waste-poultry manure composts, and one commercially-processed poultry litter. Five inorganic nitrogen (as NH4NO3-N) treatments applied at 0, 22.5, 45, 67.7, and 90 mg N/kg soil were employed to establish an N calibration curve. Yield, fescue biomass total nitrogen (as total Kjeldahl N (TKN)), and soil TKN and KCl extractable NO3−-N and NH4+-N concentrations of the organically amended treatments were compared to the inorganically fertilized treatments to determine amendment N mineralization rates and N fertilizer equivalent values (NFEV). Nitrogen mineralization rates were greatest in the poultry litter (21%) and Panorama yard waste compost (5%) amended pots. The NFEV of these amendments were 49% and 10%, respectively. Wolf Creek biosolids compost and Huck's Hen Blend yard waste compost immobilized N (−5% and 0.18%, respectively), and had percent NFEV of −0.66% and 0.19%, respectively. Rivanna biosolids compost immobilized N (−15%), but the NFEV was 30% due to the relatively high inorganic N content in the amendment. Nitrogen mineralization and NFEV were generally greater in amendments with greater total N concentrations and lower C:N values. The total N concentration and C:N values were less reliable variables in predicting N mineralization and percent NFEV when a significant portion of the total N was in the inorganic form. Nitrogen equivalency value and N mineralization for each amendment increased with time of sampling, indicating the potential for early season N insufficiency to plants fertilized with compost due to lack of synchrony between N mineralization and plant N needs.
Linewidths of the Rotational Spectra of Symmetric‐Top Molecules

Measurements of linewidths are reported for some 50 rotational transitions (J→J + 1) of the CH335Cl, CH337Cl, CH379Br, CH381Br, CH3I, CH3CN, and CH3CCH molecules. The CH3CN molecule has exceptionally wide lines (100 Mc/sec·torr) due to the large dipole moment (3.92 D). The experimental data are compared with the theoretical widths which are calculated using the Anderson theory with dipole–dipole interaction. With the exception of the CH3CCH molecule, the theoretical widths are larger than the experimental ones. The over‐all agreement between theory and experiment is within 30%.

Ultrasonic Velocities of Sound in Some Metallic Liquids. Adiabatic and Isothermal Compressibilities of Liquid Metals at Their Melting Points

The ultrasonic velocities of sound at 12 mc in 12 pure liquid metals at their melting points under atmospheric pressure and in 4 equi‐atomic liquid metallic mixtures have been determined by the use of the electronic pulse‐circuit technique.For the pure metals the adiabatic and isothermal compressibilities have been computed. The compressibilities were generally found to be somewhat larger than for the corresponding solids at room temperatures. A calculation of Gruneisen's γ for the liquid metals shows that this quantity, in the case of normal metals, does not change appreciably on going from the solid state at room temperature to the liquid at moderately elevated temperature. These facts support the familiar view that the liquid metals at temperatures not far above their melting points are in a ``solid like'' state, and that equations of state for the solid state may be applicable to such liquids.
Monetary Policy, Interest Rates, and Liquidity Premia1

The fact that central banks supply money in exchange for eligible assets, e.g. short-term treasuries, is typically neglected in macroeconomics. We augment an otherwise standard macroeconomic model and show that a liquidity premium emerges, when agents take the eligibility of assets into account. Consistent with empirical evidence, the model implies a negative relation between corporate bond yield spreads and the amount of available treasuries. The liquidity premium further provides a structural explanation for the systematic wedge between the policy rate and the marginal rate of intertemporal substitution that standard models equate. While policy rate changes are incompletely passed through to rates of return on non-eligible assets, monetary policy nevertheless exerts conventional e¤ects on real activity and ination.

Toward a transport‐based analysis of nutrient spiraling and uptake in streams

Nutrient addition experiments are designed to study the cycling of nutrients in stream ecosystems where hydrologic and nonhydrologic processes determine nutrient fate. Because of the importance of hydrologic processes in stream ecosystems, a conceptual model known as nutrient spiraling is frequently employed. A central part of the nutrient spiraling approach is the determination of uptake length (Sw), the average distance traveled by dissolved nutrients in the water column before uptake. Although the nutrient spiraling concept has been an invaluable tool in stream ecology, the current practice of estimating uptake length from steady‐state nutrient data using linear regression (called here the “Sw approach”) presents a number of limitations. These limitations are identified by comparing the exponential Sw equation with analytical solutions of a stream solute transport model. This comparison indicates that (1) Sw is an aggregate measure of uptake that does not distinguish between main channel and storage zone processes, (2) Sw is an integrated measure of numerous hydrologic and nonhydrologic processes—this process integration may lead to difficulties in interpretation when comparing estimates of Sw, and (3) estimates of uptake velocity and areal uptake rate (vf and U) based on Sw are not independent of system hydrology. Given these findings, a transport‐based approach to nutrient spiraling is presented for steady‐state and time‐series data sets. The transport‐based approach for time‐series data sets is suggested for future research on nutrient uptake as it provides a number of benefits, including the ability to (1) separately quantify main channel and storage zone uptake, (2) quantify specific hydrologic and nonhydrologic processes using various model parameters (process separation), (3) estimate uptake velocities and areal uptake rates that are independent of hydrologic effects, and (4) use shortterm, non‐plateau nutrient additions such that the effects of regeneration and mineralization are minimized. In summary, the transport‐based, time‐series approach provides a means of estimating traditional measures of nutrient uptake (Sw, vf , U) while providing additional information on the location and magnitude of uptake (main channel versus storage zone). Application of the transport‐based approach to time‐series data from Green Creek, Antarctica, indicates that the bulk of nitrate uptake (~74% to 100%) occurred within the main channel where benthic uptake by algal mats is a likely process. Substantial uptake (~26%) also occurred in the storage zone of one reach, where uptake is attributed to the microbial community.
SEED BLENDING OF OAT (AVENA SATIVA L.) AND CANOLA (BRASSICA NAPUS L.) UNDER VARIABLE SEED PROPORTIONS ENHANCED FORAGE PRODUCTIVITY AND NUTRITIONAL QUALITY

Optimization of the proportionate share of component crops in mixed intercropping systems is vital for achieving the added advantage. This field study investigated the productivity of seed blended crops of oats and canola under different seed ratios (80:20, 60:40, 40:60, 20:80 and 50:50%), while their solitary crops were kept for comparison. The agronomic yield attributes, forage biomass and nutritional quality were taken as response variables. The yield attributes of oat in intercropping decreased significantly (p≤0.05) in comparison to the monoculture. Green forage yield and dry matter biomass of component crops decreased with the reduction of their seed proportion in mixtures. However, the maximum productivity (92 t ha) of intercropping system was noted for oat and canola sown in 60:40 seed blending ratio, which was closely followed by 80:20 seed proportion. The crude protein (p≤0.01) and total ash (p≤0.05) contents of mixed forage were improved with increased share of canola seed in binary mixtures, while the pure stand of canola yielded the highest quality forage. However, seed blending of oat and canola in 60:40 seed proportion may be preferred owing to higher productivity (19%) and improved nutritional quality of mixed forage.
