Fósforo na qualidade de sementes de soja e consequente desempenho na produção de grãos

O objetivo do presente trabalho foi avaliar o efeito da aplicacao de diferentes doses de fosforo na qualidade fisiologica da semente, bem como a produtividade na geracao seguinte. O experimento foi conduzido em Itiquira, MT, nas safras 2009/2010 e 2010/2011. Na safra 2009/2010, as sementes de soja foram semeadas sob diferentes doses de fosforo na linha a partir da analise quimica do solo, nas seguintes proporcoes, de acordo com a recomendacao: controle - 0%, 50%, 100%, 150% e 200% da dose de P2O5 recomendada. A fonte de fosforo utilizada foi superfosfato triplo. A adubacao de cobertura com 100 kg/ha de cloreto de potassio foi distribuida a lanco em pos-emergencia. Apos a colheita, foram analisados a viabilidade e o vigor das sementes, alem dos componentes do rendimento, como altura de insercao do primeiro legume, numero de legumes por planta, numero de sementes por planta, numero de plantas por metro, produtividade e nutrientes minerais na semente. Parte da semente foi armazenada com umidade de 13%, em condicoes controladas de temperatura entre 20° e 22o. Na safra 2010/2011, as sementes provenientes de cada tratamento da safra 2009/2010 foram semeadas em campo, recebendo adubacao conforme analise de solo. A area util para cada tratamento foi de 270 m². Apos a colheita dos tratamentos, no segundo ano, avaliouse a produtividade da cultura. O delineamento experimental foi de blocos ao acaso, com cinco repeticoes. As medias foram submetidas a analise de variância e, posteriormente, submetidas ao teste de Dunnett e regressao polinomial. Sementes com teores superiores de fosforo influenciam positivamente o numero de sementes e de legumes por planta, contribuindo para o aumento de produtividade da soja. Concentracoes maiores de fosforo na linha de semeadura melhoram o vigor das sementes de soja, alem de contribuir para o aumento de fosforo, ferro e zinco das sementes produzidas. No entanto, as concentracoes de manganes sao reduzidas
Isolation and Characterization of Effective Yeast Strains for Bioethanol Production

Since recent years, bioethanol has become greatly interested as an alternative to petroleum derived fuel. The recent study aims at searching for effective native yeast strains for bioethanol production. In this study, fourteen yeast strains that were collected from different sources were identified based on carbon and nitrogen assimilation tests and fermentative capacity tests. Among them, five yeast strains could be assumed as Saccharomyces cerevisiae according to the conventional identification. The ethanol and temperature tolerant tests were also carried out. According to ethanol and temperature tolerant tests, the isolate Y3 had the highest temperature and ethanol tolerant level (45oC and 10% v/v respectively).
Potential antihyperlipidemic polyketones from endophytic Diaporthe sp. JC-J7 in Dendrobium nobile

Eleven new polyketones named diaporthsins A–K (1–11) were isolated from the fermentation of Diaporthe sp. JC-J7. The chemical structures of compounds (1–11) were elucidated by spectroscopic methods including HRESIMS, 2DNMR, NMR and chemical methods. Compound 11 features an unusual acyclic polyketone–phenolic polyketone hybrid structure that integrates the characteristics of different fungal metabolites (cytosporone and multiplolide). Compound 3 was the only C12-polyketone obtained in this research. These new polyketones showed inhibitory activity on triglycerides (TG) in steatosis hepatocyte L-02 cells. Among them, compound 5 and (4E)-6,7,9-trihydroxydec-4-enoic acid displayed inhibitory activities on TG in steatotic L-02 cells with inhibition ratios of 26% and 21% at concentration of 5 μg mL−1; also, inhibition ratios of 8-O-acetylmultiplolide A and phomopsisporone A at concentration of 5 μg mL−1 were calculated to be about 24% and 16%, respectively, which were equivalent to the antihyperlipidemic activity of lovastatin. The preliminary structure–activity relationship indicated that acetyl at C-8 can increase the antihyperlipidemic activity of multiplolide A and the glycol ester and hydroxyl at C-6 can also increase the corresponding activity of diaporthsin B.
Underwater Laser Treatment of PET: Effect of Processing Parameters on Surface Morphology and Chemistry

Rapid development of nanotechnology in processes of metal nanoparticle immobilization on solid surfaces, especially polymeric ones, requires the study of particular issues within these complex approaches. Numerous studies have been published on laser light mediated manipulation with single metal nanoparticles in water environment and even laser assisted immobilization of such particles on polymeric substrate, however, not much has been reported on fundamentals of underwater laser processing of polymer itself, especially regarding to resulting surface morphology and chemistry. In this work, we study surface morphology (atomic force microscopy (AFM)) and chemistry (angle-resolved X-ray photoelectron spectroscopy (ARXPS) and inductively coupled plasma-mass spectroscopy (ICP-MS)) of polyethylene terephthalate (PET) after underwater laser treatment in broad scale of applied laser fluencies and operating voltages. Due to typical dependence of laser efficiency on operating voltage, induced nanostructures on PET exhibited a noticeable symmetry spread out around the maxima of laser efficiency for low laser fluencies. The study of surface chemistry revealed that at high laser fluencies, photochemical decomposition of macromolecular polymer structure took place, resulting in rapid material ablation and in balanced chemical composition of the surface throughout the studied profile. Enrichment of the water bath by the low-molecular polymer degradation products proves that ablation mechanism is the governing process of surface nanostructure formation in underwater laser processing.
A General Two‐Step Strategy–Based High‐Throughput Screening of Single Atom Catalysts for Nitrogen Fixation

Electrocatalytic or photocatalytic N2 reduction holds great promise for green and sustainable NH3 production under ambient conditions, where an efficient catalyst plays a crucial role but remains a long‐standing challenge. Here, a high‐throughput screening of catalysts for N2 reduction among (nitrogen‐doped) graphene‐supported single atom catalysts is performed based on a general two‐step strategy. 10 promising candidates with excellent performance are extracted from 540 systems. Most strikingly, a single W atom embedded in graphene with three C atom coordination (W1C3) exhibits the best performance with an extremely low onset potential of 0.25 V. This study not only provides a series of promising catalysts for N2 fixation, but also paves a new way for the rational design of catalysts for N2 fixation under ambient conditions.
Genetic Diversity among Some Asparagus Species
using rDNA ITS, cpDNA trnL Intron Sequence
and Screening for Antioxidant Activity

Three species of genus Asparagus native to Lake Van Basin of Turkey were analyzed using internal transcribed spacer (ITS) and cpDNA trnL intron sequence. Furthermore, these species were screened for their antioxidant activity and total phenolic and flavonoid contents. Phylogenetic analysis based on ITS data revealed two clades: the first clade consisted of Asparagus persicus and Asparagus officinalis, and clade II consisted of Asparagus palaestinus. Similarly, phylogenetic analysis using trnL intron sequence revealed two clades. In term of total phenolic content and total flavonoid content, the highest value were measured for acetone extract of Asparagus persicus sample No. 2 and Asparagus persicus sample No. 6, respectively. The highest antioxidant activity using FRAP assay was found for Asparagus persicus sample No. 3. We concluded that these species could be useful for increasing genetic diversity among cultivated species and for breeding.
Influence of Plant Growth Promoting Rhizobacteria, Compost, and Biochar of Azolla on Rosemary (Rosmarinus Officinalis L.) Growth and Some Soil Quality Indicators in a Calcareous Soil

ABSTRACT In order to study the effect of plant growth promoting rhizobacteria (PGPR), Azolla compost and Azolla biochar on some soil quality indicators and rosemary growth, a greenhouse experiment was conducted in a completely randomized design with six replications. Treatments consisted of T1 (control), T2 (1% Azolla compost), T3 (1% Azolla biochar), T4 (PGPR (P. fluorescens), T5 (1% compost + PGPR) and T6 (1% biochar + PGPR). Rosemary growth parameters and nutrients concentration increased in all treatments compared to control. Treatments increased soil nutrient concentrations, soil microbial respiration (SMR) and microbial biomass C (MBC) but decreased soil metabolic quotient (qCO2) compared to control treatment. A significant enhancement in rosemary growth occurred due to the improved soil quality as a result of organic fertilizers application, particularly by co-application of P. fluorescens and compost or biochar of Azolla.
An In-Situ Thermogravimetric Study of Pyrolysis of Rice Hull with Alkali Catalyst of CaCO3

Pyrolysis of rice hull (RH) with the presence of CaCO3 catalyst was carried out in this study to understand the effect of alkali catalyst in the thermal degradation behaviour and evaluate the kinetic parameter of rice hull for bio-oil or syngas production. Five different heating rates of the pyrolysis experiments at 10, 20, 30, 50, and 100 Kmin−1 were carried out in thermogravimetric analysis (TGA) equipment. Model fitting kinetic Coats Redfern integral method was applied in this study to estimate the activation energy (EA) and pre-exponential (A) value of catalytic pyrolysis in RH. The results showed that the maximum degradation increased from 6.69 to 52.67 wt% min−1 as heating rates increases from 10 to 100 Kmin−1. Besides that, the EA of the catalytic pyrolysis for RH using CaCO3 catalyst 60.86 kJmol−1 which is lower than other similar pyrolysis reaction reported in literature i.e. 77.4 kJ/mol. Meanwhile, the A value for the catalytic pyrolysis for RH using CaCO3 catalyst was 4.68×1010 min−1 which is significantly higher than 1.1×106 min−1 as reported in literature for non-catalytic pyrolysis of rice husk.
Comparison of Antibacterial Activity of Three Endodontic Sealers against Enterococcus faecalis

one of the important property of endodontic sealer is antibacterial activity. This study aimed to compare the antibacterial properties of three common and widely used sealers: MTA-FillApex, AH Plus, and AH26 against Enterococcus faecalis. In this study, 25 Blood Agar plates were prepared, in each of which 5 wells were devised. In three wells, three sealers of MTA-FillApex, AH Plus, and AH26 were placed. Ampicillin was poured into the fourth well as the positive control group. Finally, distilled water was poured into the fifth well as the negative control group. Concurrently, 1/10 ml of Enterococcus faecalis bacteria suspension with a concentration of 0.5 McFarland was cultivated on the plates. Following 48 hours of incubation, the diameter of inhibition zone around the wells was measured. Finally, the obtained results were analyzed by one-way ANOVA, fisher LSD, Fisher individual 95% Cl. The results of our study on 25 plates after 48 h indicated AH26 sealer with the mean zone of inhibition diameter of 16.44 mm had the greatest antibacterial effects. AH26 was followed by MTAFillApex with the mean zone of inhibition diameter of 15.44 mm. Finally, the weakest antibacterial effect was related to AH Plus sealer, with the mean zone of inhibition diameter of 10.2 (p<0.1000). According to our study, AH26 sealer has the greatest power and antibacterial properties against Enterococcus faecalis bacteria, followed by MTA-FillApex, and AH plus (as the weakest antibacterial agent against the mentioned bacteria).
Molecular characterization of glutathione S-transferase, endothelial nitric oxide synthase and Vitamin D receptor genes in breast cancer cases

Background: Enzymes of the Glutathione S-transferase system (GST) modulate the effects of exposure to several cytotoxic and genotoxic agents. Nitric oxide (NO) is constitutively synthesized in the endothelium by endothelial nitric oxide synthase (eNOS) and acts as a pleiotropic regulator involved in carcinogenesis. Vitamin D levelsmay influence breast cancer development. The vitamin D receptor(VDR) is a crucial mediator for the cellular effects of vitaminD and additionally interacts with other cell-signaling pathwaysthat influence cancer development. Objectives: To check for the association of polymorphisms of GST, eNOS3 and VDR genes with the susceptibility and severity of breast cancer in Egyptian cases. Subjects: This work included 100 cases with breast cancer and 100 healthy individuals. The mean age of cases was 48.31±11.40 years. They included 100 females. Methods: DNA was amplified using PCR-RFLP for detection of polymorphisms related to eNOS3 and VDR , also DNA was amplified using PCR-SSP for detection of polymorphisms related to GST and calculating the odds ratios and their 95% confidence intervals. Results: Total cases showed high significant frequency of eNOS3-786 CC (P<0.05, OR=18.58) genotypes, GSTT1(null) (OR = 2.68; CI 95%=1.51-4.75; p=0.001). These were considered risk genotypes for disease susceptibility. On the other hand, total cases showed low significant frequency with homozygosity for eNOS3-786 TT (P=0.01) and the GSTT1 gene was present in 42.0% of the cancers and in 66.0% of controls (OR = 0.37; CI 95%= 0.21-0.66; p=0.001). These may be considered low risk genotypes. No significant difference in frequencies of null and present genotypes of GSTM1 and VDR FOKI in total cases compared to controls. Conclusions: Polymorphisms related to eNOS3-786, GSTT1 and VDR FOKI genes may be considered genetic markers for BC among Egyptian cases. This may have potential impact on family counselling as well as future management plans.
Productie van zoutwateralgen voor toepassingen in food (en feed) deelrapport II : Werkpakketten 1&2 van project Foodgrade productie van zoutwateralgen: deelrapport II: Batchexperimenten met zoute reststromen en verschillende mariene algensoorten

There is a lot of interest in the commercial production of microalgae for food applications. Producing marine microalgae in reactors with LED lights has several advantages. Marine microalgae contain valuable components such as antioxidants, and high salinity levels in production systems can prevent contaminations with other organisms. Production in closed systems at different light wavelengths (colours) can result in high biomass concentrations and better control of biomass growth and production of valuable components. Several industries produce salt waste streams, often with associated processing costs. In this report a number of these streams is discussed (liquid fraction of cattle manure biogas slurry, potassium and sodium brines from dairy industries, brackish groundwater, seawater, purge water and brine from salt processing). An option for reducing costs (for disposal or treatment) is the production of marine microalgae on these streams. The algae can be used as food (ingredient). This report describes batch experiments in which growth of nine microalgae species was tested on these waste streams: Nannochloropsis gaditana, Phaeodactylum tricornutum, Tetraselmis chuii (two strains), Porphyridium purpureum, Dunaliella salina, Odontella aurita, Arthrospira platensis and Tetraselmis tetrathele. The experiments were performed in well plates and 1 L reactors with artificial (LED) lights. From the tests it was concluded that several of the algae species can be cultured on different waste streams. The best results were obtained with N. gaditana, A. platensis, P. purpureum en T. chuii (AF&F) on (diluted) brines from the dairy industry and the diluted liquid fraction of biogas slurry. It is recommended to optimize some of these combinations further in experiments.
Valorization of Mining Waste in the Synthesis of Organofunctionalized Aluminosilicates for the Esterification of Waste from Palm Oil Deodorization

The synthesis of aluminosilicate Al-MCM-41 was performed using mining kaolin waste as an alternative source of silicon and aluminum to add value to this waste. In a preliminary stage, acid leaching was carried out with the kaolin residue with three different durations (1, 1.5 and 2 h) to evaluate the leaching time that provided the highest amounts of silicon and aluminum in the tailings. Molecular sieves were synthesized by the hydrothermal method and calcined at 550 °C to eliminate the surfactant. X-ray diffractograms of the synthesized samples revealed that the sample AM41-2H, obtained from kaolin leached for 2 h (MC7-2H), presented the best structural arrangement due to the presence of 2θ angles close to 2.32°, a specific surface area of 1016 m2·g–1, a pore volume of 0.80 cm3·g–1, and a pore diameter of 3.14 nm, which are characteristic of Al-MCM-41. A sample of AM41-2H was functionalized with 3-mercaptopropyltrimethoxysilane (MTPS) (5 mmol MTPS/g AM41-2H). To eliminate excess unaltered MTPS on the sur.
Effect of Organic Waste and Humic Acid on Some Growth Parameters and Nutrient Concentration of Pistachio Seedlings

ABSTRACT Pistachio crops in Iran are grown in soil with low soil organic matter. Therefore, a field experiment was conducted at Izadyaran Company, Sirjan, Iran to study the effects of municipal solid waste compost (MSWC), cow manure, and methods of humic acid application (soil and foliar) on growth parameters and nutrients concentration of pistachio seedlings in a complete randomized design with six replications for two years (2011–2013). Results showed that cow manure decreased the leakage percent and maximum leaf number and leaf surface area were obtained in MSWC with foliar application of humic acid and cow manure without humic acid, respectively. The highest chlorophyll b and carotenoid were observed in the second year with cow manure treatment whereas foliar application of humic acid increased total chlorophyll. Calcium (Ca) and iron (Fe) decreased in the second year. At the first year Cow manure application increased phosphorus (P) and manganese (Mn) but in the second year increased magnesium (Mg) concentration. MSWC at the first year increased copper (Cu) and zinc (Zn) concentration. Cow manure and foliar application of humic acid increased the Nitrogen (N) concentration in the first year. These results may have implications for pistachio production in arid and semi-arid soils.
Aerodynamic Characteristics of a 600-MWe Utility Boiler Incorporating Multi-Injection and Multi-Staging: Influences of the Distance between Adjacent Two Burners

ABSTRACT This work studied the effect of varying the distance between adjacent two burners (DBATB) in a 600 MWe supercritical down-fired utility boiler incorporating multi-injection and multi-staging. Cold-state tests involving airflow trajectory tracing in an actual boiler with a DBATB of 971 mm and 1:20 scale model tests with DBATB values of 971, 1329, and 1687 mm were conducted to study the effects of adjusting DBATB on aerodynamic characteristic. The results indicate that increasing the DBATB had a minimal effect on the symmetric W-shaped flow pattern. A downward airflow rushing the hopper wall was observed at a DBATB of 971 mm, while increasing the value from 971 to 1687 mm promoted decay of the downward airflow velocity in association with gradually enhanced airflow diffusion toward the furnace center. Simultaneously, the airflow rushing the hopper wall disappeared, while the airflow dimensionless penetration depth and the volume of air flowing into the hopper zone were respectively reduced by 12% and 20%. Increasing the DBATB contributes to prevent the actual downward flame from rushing the hopper water wall and form a more uniform heat release along the furnace width. This effect would be expected to avoid local overheating and bursting of the water-wall tube in an actual operational boiler, and an optimal DBATB value of 1687 mm is recommended for this purpose.

Vapor Adsorption Transient Test Facility for Dehumidification and Desorption Studies

The steady state performance testing of industrial-scale energy wheels requires large-scale and advanced instrumentation to analyze large volumes of data. In order to address the feasibility of laboratory-scale studies, experimental modelling and data simulation have been successfully performed by means of the transient and cyclic testing of a heat exchanger within an energy wheel setup in a parallel-flow air stream configuration. However, major challenges have been encountered in terms of predicting the effectiveness of a counter-flow energy wheel configuration in different operating conditions via the use of a transient test setup in a parallel-flow configuration. In the present study, we report the modification of a transient test facility intended to facilitate the more accurate simulation of a full-scale energy wheel operation in a small-scale test facility. A new test section was designed to: (1) enable tests in both counter-flow and parallelflow configurations; (2) afford automated cyclic testing and achieve the reliable simulation of the energy wheels dehumidification/regeneration cycles; and (3) enhance the accuracy and reduce the uncertainty of the relative humidity (RH) measurements through utilization of the bag sampling method. The latter method is shown to yield greater accuracy with regard to the RH in non-isothermal operating conditions, as well as to reduce the data processing required for the estimation of latent effectiveness.
Kinetic heterogeneity of an experimental tumour revealed by bromodeoxyuridine incorporation and mathematical modelling

In the present paper we propose a method of analysis of the cell kinetic characteristics of in vivo experimental tumours, that uses DNA-BrdUrd flow cytometry data at various times after the BrdUrd injection and mathematical modelling. The model of the cell population takes into account the cell-to-cell heterogeneity of the progression rate across cell cycle phases within the tumour, and assumes a strict correlation between the durations of S and G2M phases. The model also allows for a nonconstant DNA synthesis rate across S phase. In addition, the measurement process is modeled, considering the possibility of nonimpulsive labelling and providing a representation of the time course of the bivariate DNA-BrdUrd fluorescence distribution. Sequential DNA-BrdUrd distributions were obtained from a human ovarian carcinoma transplanted in mice. From these data, that included the fractional density and the mean BrdUrd-fluorescence of BrdUrd-positive cells as a function of the DNA-fluorescence, kinetic parameters such as the potential doubling time (Tpot) and the mean and variance of the transit times in S and G2M phases, were estimated. This study revealed the presence of a substantial heterogeneity in S and G2M phases within the cell population. Moreover, our analysis suggests a nonnegligible effect of the BrdUrd pharmacokinetics in the in vivo cell labelling.
