    The Long Valley Caldera straddles the eastern edge of the Sierra Nevada Batholith and the western edge of the Basin and Range Province, and represents one of the largest caldera complexes on Earth. The caldera is intersected by numerous fault systems, including the Hartley Springs Fault System, the Round Valley Fault System, the Long Valley Ring Fault System, and the Hilton Creek Fault System, which is our main region of interest. The Hilton Creek Fault System appears as a single NW-striking fault, dipping to the NE, from Davis Lake in the south to the southern rim of the Long Valley Caldera. Inside the caldera, it splays into numerous parallel faults that extend toward the resurgent dome. Seismicity in the area increased significantly in May 1980, following a series of large earthquakes in the vicinity of the caldera and a subsequent large earthquake swarm which has been suggested to be the result of magma migration. A large portion of the earthquake swarms in the Long Valley Caldera occurs on or around the Hilton Creek Fault splays. We are conducting an interdisciplinary geophysical study of the Hilton Creek Fault System from just south of the onset of splay faulting, to its extension into the dome of the caldera. Our investigation includes ground-based magnetic field measurements, high-resolution total station elevation profiles, Structure-From-Motion derived topography and an analysis of earthquake focal mechanisms and statistics. Preliminary analysis of topographic profiles, of approximately 1 km in length, reveals the presence of at least three distinct fault splays within the caldera with vertical offsets of 0.5 to 1.0 meters. More detailed topographic mapping is expected to highlight smaller structures. We are also generating maps of the variation in b-value along different portions of the Hilton Creek system to determine whether we can detect any transition to more swarm-like behavior towards the North. We will show maps of magnetic anomalies, topography

    2001-05-01

    Five rye lines exhibiting a wide range of extract viscosities were evaluated for the rheological and baking properties of their flours, individually and in blends with hard red spring wheat flour. Commercial cultivars of rye and triticale were included in the study as controls. Extract viscosities of rye flours were higher than those of corresponding wholemeals, indicating shifting of water-extractable arabinoxylan into flour during roller milling. Falling numbers of the rye flours correlated positively with their extract viscosities in the presence (r = 0.73, p < 0.05) or absence (r = 0.65, p < 0.05) of an enzyme inhibitor. Farinograms revealed the weakness of rye and triticale flours compared to wheat flour. Extract viscosities of rye flours were negatively correlated (r = -0.65, p < 0.05) with mixing tolerance index and positively correlated (r = 0.64, p < 0.05) with dough stability, suggesting a positive impact of extract viscosity on dough strength. Extract viscosity was negatively correlated (r = -0.74, p < 0.05) with loaf volume and specific volume (r = -0.73, p < 0.05) and positively correlated (r = 0.73, p < 0.05) with loaf weight of rye/wheat bread. Overall, the results indicated that 30% of flour from high or low extract viscosity rye could be incorporated into rye/wheat breads without seriously compromising bread quality. Inclusion of rye, particularly high extract viscosity rye, in chick diets seriously impeded growth performance and feed efficiency. Part of the arabinoxylan survived bread-making and exerted an effect on chicks, although substantially lower digesta viscosities were observed in chicks fed rye bread diets than in those fed rye wholemeals.

    Callejo, M. J.; Bujeda, C.; Rodriguez, G.; Chaya, C.

    2009-07-01

    The aim of this work is to study the effect of rye flour on the rheological properties of doughs. Rye meals of two different extraction rate (65% and 85%) were blended in different proportions with wheat flours. The viscoelastic behaviour of the sample blends was determined by a Chopin alveograph. The effect of rye flour on dough rheology during mixing was determined by a Chopin consistograph. It was found that Chopin Consistograph methodology was not suitable for determining water absorption capacity in blends with rye. It has been confirmed that adjustment of dough hydration in baked products incorporating rye flour must be taken into account, depending not only on the wheat-to-rye ratio but also on the rye meals extraction rate.

    Rye breads made from commercial rye blends lower the postprandial insulin demand and appear to facilitate glucose regulation. However, differences in metabolic responses may occur between rye varieties. In the present work, five rye varieties (Amilo, Evolo, Kaskelott, Picasso. and Vicello) and a commercial blend of rye grown in Sweden were investigated with regard to their postprandial insulin, glucose, and appetite regulation properties in a randomized crossover study in 20 healthy subjects. The rye flours were baked into whole grain breads, and a white wheat bread (WWB) was used as reference (50 g of available starch). Picasso and Vicello rye bread showed lower glycemic indices (GIs) compared with WWB (80 and 79, respectively) (P bread made from not only Vicello and Picasso but also Amilo and Kaskelott displayed significantly lower insulin indices (IIs) than WWB (74-82). A high GP and GP(2) and a low GI were related to a lower II and insulin incremental peak. A high content of insoluble fibers and a high GP(2) were related to a higher subjective satiety in the early and late postprandial phase (tAUC 0-60 min and tAUC 120-180 min, respectively). The results suggest that there may be differences in the course of glycemia following different rye varieties, affecting postprandial insulin responses and subjective satiety.

    Rye products typically induce low insulin responses and appear to facilitate glucose regulation. The objective of this study was to investigate differences in postprandial glucose, insulin, and satiety responses between breads made from five rye varieties. Breads made from whole grain rye (Amilo, Rekrut, Dankowski Zlote, Nikita, and Haute Loire Pop) or a white wheat bread (WWB) were tested in a randomized cross-over design in 14 healthy subjects (50 g available starch). Metabolic responses were also related to the composition of dietary fiber and bioactive compounds in the breads and to the rate of in vitro starch hydrolysis. The Amilo and Rekrut rye breads induced significantly lower insulin indices (II) than WWB. Low early postprandial glucose and insulin responses (tAUC 0-60 min) were related to higher amounts of caffeic, ferulic, sinapic, and vanillic acids in the rye breads, indicating that the phenolic acids in rye may influence glycemic regulation. All rye breads induced significantly higher subjective feelings of fullness compared to WWB. A low II was related to a higher feeling of fullness and a lower desire to eat in the late postprandial phase (180 min). The data indicate that some rye varieties may be more insulin-saving than others, possibly due to differences in dietary fiber, rate of starch hydrolysis, and bioactive components such as phenolic acids.

  3. Isolation and characterization of an isoamylase gene from rye

    2013-12-01

    Full Text Available Genomic DNA and cDNA sequences of an isoamylase gene were isolated and characterized from the rye genome. The full-lengths of the rye isoamylase gene are 7351 bp for genomic DNA and 2364 bp for cDNA. There are 18 exons and 17 introns in the genomic sequence, which shares a similar organization with homologous genes from Aegilops tauschii, maize, rice and Arabidopsis. Exon regions of rye and other plant isoamylase genes are more conserved than the introns. High sequence similarity (> 95% was observed in mature proteins of isoamylase genes originating from rye, Ae. tauschii, wheat and barley. The transcript profile revealed that rye isoamylase is mainly expressed in the seed endosperm with a maximum level at the middle developmental stage (15 DPA. A phylogenetic tree based on the deduced aa sequences of mature proteins from rye and other plant isoamylases indicated that rye isoamylase is more closely related to Ae. tauschii wDBE1 and wheat iso1. This is the first report on identification and characterization of the isoamylase gene from rye, making it possible to explore the roles of this enzyme for amylopectin development in rye and triticale.

    The U.S. Geological Survey, in cooperation with the South Carolina Department of Health and Environmental Control (SCDHEC), is drilling a deep geologic test well at Hilton Head Island, S.C. The test well is scheduled to run between mid-March and early May 2011. When completed, the well will be about 1,000 feet deep. The purpose of this test well is to gain knowledge about the regional-scale Floridan aquifer, an important source of groundwater in the Hilton Head area. Also, cores obtained during drilling will enable geologists to study the last 60 million years of Earth history in this area.

    Bush, Peter W.

    1988-01-01

    Freshwater to supply Hilton Head Island, S.C., is obtained from the upper permeable zone of the Upper Floridan aquifer. Long-term pumping at Savannah, Ga., and the steadily increasing pumping on Hilton Head Island, have lowered Upper Floridan heads near the center of the island from about 10 feet above sea level to about 6 to 7 feet below sea level. The seaward hydraulic gradient that existed before pumping began has been reversed, thus increasing the potential for saltwater intrusion. Simulations of predevelopment, recent, and future ground-water flow in the Floridan aquifer system beneath the north end of Hilton Head Island and Port Royal Sound are presented. A finite-element model for fluid-density-dependent ground-water flow and solute transport was used in cross section. The general configuration of the simulated predevelopment flowfield is typical of a coastal aquifer having a seaward gradient in the freshwater. The freshwater flows toward Port Royal Sound over an intruding wedge of saltwater. The simulated flowfield at the end of 1983 shows that ground water in the Floridan aquifer system beneath most of Hilton Head Island has reversed its predevelopment direction and is moving toward Savannah. The distribution of chloride concentrations, based on simulation at the end of 1983, is about the same as the predevelopment distribution of chloride concentrations obtained from simulation. Results of two 50-year simulations from 1983 to 2034 suggest that there will be no significant threat of saltwater intrusion into the upper permeable zone of the Upper Floridan aquifer if heads on Hilton Head Island remain at current levels for the next 45 to 50 years. However, if head decline continues at the historical rate, any flow that presently occurs from the north end of the island toward Port Royal Sound will cease, allowing lateral intrusion of saltwater to proceed. Even under these conditions, chloride concentrations in the upper permeable zone of the Upper Floridan

    Full Text Available 14.00 The results of molecular analysis of 45 rye taxa (Secale cereale L. represented by agricultural varieties originated from Central Europe and the Union of Soviet Socialist Republics (SUN are presented. The genetic diversity of rye cultivars by 6 SSR markers was evaluated. Six specific microsatellite primer pairs produced 58 polymorphic alleles with an average of 9.7 alleles per locus. The number of alleles ranged from 6 (SCM2 to 14 (SCM86. Genetic polymorphism was characterized based on diversity index (DI, probability of identity (PI and polymorphic information content (PIC. The diversity index (DI of SSR markers ranged from 0.5478 (SCM2 to 0.887 (SCM86 with an average of 0.778. The lowest value of polymorphic information content was recorded for SCM2 (0.484 and the highest value for SCM86 (0.885 of PIC was detected in SCM86 with an average of 0.760.The dendrogram of genetic similarity was constructed, based on UPGMA algorithm. The hierarchical cluster analysis divided rye genotypes into 4 main clusters. The first cluster of 14 genotypes was subdivided in two subclusters (1a and 1b where 50% of genotypes were Czechoslovak origin. The second cluster contained four genotypes were three (75% of them had Czech or Czechoslovak origin. In the third subcluster separated three rye genotypes of different origin. The rest (24 of rye genotypes in the fourth cluster were divided into two subclusters (4a and 4b where clearly separated group of Polish (4aa and Czech and Czechoslovak (4ab genotypes. Two genotypes of 4aa subcluster (Wojcieszyckie and Dankowskie Nowe from Poland were genetically the closest. In the dendrogram alle genotypes were differentiated and clustering partially reflects geographic origin of studied rye genotypes. In this experiment, SSRs markers proved to be a high informative and usefull tool in genetic diversity research for the distinguishing and characterization of close related varieties.

  13. Involvement of Disperse Repetitive Sequences in Wheat/Rye Genome Adjustment

    Directory of Open Access Journals (Sweden)

    Manuela Silva

    2012-07-01

    Full Text Available The union of different genomes in the same nucleus frequently results in hybrid genotypes with improved genome plasticity related to both genome remodeling events and changes in gene expression. Most modern cereal crops are polyploid species. Triticale, synthesized by the cross between wheat and rye, constitutes an excellent model to study polyploidization functional implications. We intend to attain a deeper knowledge of dispersed repetitive sequence involvement in parental genome reshuffle in triticale and in wheat-rye addition lines that have the entire wheat genome plus each rye chromosome pair. Through Random Amplified Polymorphic DNA (RAPD analysis with OPH20 10-mer primer we unraveled clear alterations corresponding to the loss of specific bands from both parental genomes. Moreover, the sequential nature of those events was revealed by the increased absence of rye-origin bands in wheat-rye addition lines in comparison with triticale. Remodeled band sequencing revealed that both repetitive and coding genome domains are affected in wheat-rye hybrid genotypes. Additionally, the amplification and sequencing of pSc20H internal segments showed that the disappearance of parental bands may result from restricted sequence alterations and unraveled the involvement of wheat/rye related repetitive sequences in genome adjustment needed for hybrid plant stabilization.

    Full Text Available Abstract The positive accepted savoury taste of rye bread is dependent on acetate concentration in the dough of such breads. In order to study how calcium acetate influences rye bread properties, the pH of rye doughs fortified with calcium acetate and the resulting volume of the breads were measured. Furthermore, CO2 formation of yeast with added calcium acetate and yeast with different pH levels (4, 7, 9 were measured. Thereby, it was determined that the addition of calcium acetate increased the pH of dough from 4.42 to 5.29 and significantly reduced the volume of the breads from 1235.19 mL to 885.52 mL. It could be proven that bread volume was affected by a 30.9% lower CO2 amount production of yeast, although bread volume was not affected by changing pH levels. Due to reduced bread volume, high concentrations of calcium acetate additions are not recommended for improving rye bread taste.

    Thirteen monoclonal antibodies (MAbs) were produced against Lol p I (Rye I), the major Lolium perenne (rye grass) pollen allergen. Spleen cells from A/J and SJL mice immunized with highly purified Lol p I (Lol I) were allowed to fuse with cells from the non-secreting Sp2/0-Ag14 myeloma cell line. Each MAb was analyzed for antigenic specificity by radioimmunoassay (RIA) using 125I-Lol I. The epitope specificities of seven of the MAbs were examined by competitive binding against a labelled standard MAb for the Lol I antigen (Ag). The dissociation constant, Kd, of one MAb (No. 3.2) that was studied most extensively was determined by double Ab RIA to be 3.5 X 10(-6) L/M. This MAb recognized the related 27,000-30,000 Group I glycoproteins found in the pollens of nine other species of grass pollens tested, including weak binding to Bermuda grass Group I (Cyn d I), which by conventional analysis using polyclonal anti-Lol I serum shows no detectable binding. Monoclonal antibody No. 3.2 was coupled covalently to Sepharose 4B and used to prepare highly purified Lol I from a partially purified rye pollen extract. Finally, an RIA was developed which permitted the analysis of the Group I components in rye grass and nine other grass pollen species. The latter assay is likely to prove useful in the standardization of grass pollen extracts according to their Group I contents.

    High temperature extrusion cooking of rye was used as a pretreatment for ethanol fermentation, and yeasts and bacteria were compared for their fermentation rates. Extrusion cooking caused, on average, a 7.5% increase in ethanol yield in comparison to autoclaved samples. The best results were achieved for grain with a moisture of 21-23% which was extruded at temperatures of 160-180 C. Extrusion decreased the relative viscosity of rye grain water extracts, so it was possible to mash it without {alpha}-amylase. The efficiency of fermentation of extruded rye without Termamyl was equal to that of autoclaved and traditionally mashed rye (using {alpha}-amylase). The rate of fermentation of extruded rye grain by Zymomonas was higher during the first stage, but the final ethanol yield was similar for the bacterium and the yeast. Through both microorganisms gave good quality distillates, the concentration of compounds other than ethanol achieved from extruded rye mashes, which were fermented by Z. mobilis, was five times lower than for yeasts.

    Published studies focused on characterizing the allelopathy-based weed suppression by rye cover crop mulch have provided varying and inconsistent estimates of weed suppression. Studies were initiated to examine several factors that could influence the weed suppressiveness of rye: kill date, cultivar, and soil fertility. Ten cultivars of rye were planted with four rates of nitrogen fertilization, and tissue from each of these treatment combinations was harvested three times during the growing season. Concentrations of a known rye allelochemical DIBOA (2,4-dihydroxy-1,4-(2H)benzoxazine-3-one) were quantified from the harvested rye tissue using high performance liquid chromatography (HPLC). Phytotoxicity observed from aqueous extracts of the harvested rye tissue correlated with the levels of DIBOA recovered in harvested tissue. The amount of DIBOA in rye tissue varied depending on harvest date and rye cultivar, but was generally lower with all cultivars when rye was harvested later in the season. However, the late maturing variety 'Wheeler' retained greater concentrations of DIBOA in comparison to other rye cultivars when harvested later in the season. The decline in DIBOA concentrations as rye matures, and the fact that many rye cultivars mature at different rates may help explain why estimates of weed suppression from allelopathic agents in rye have varied so widely in the literature.

    Full Text Available Studying gene expression in wheat–rye translocation lines is complicated due to the presence of homeologs in hexaploid wheat and high levels of synteny between wheat and rye genomes (Naranjo and Fernandez-Rueda, 1991 [1]; Devos et al., 1995 [2]; Lee et al., 2010 [3]; Lee et al., 2013 [4]. To overcome limitations of current gene expression studies on wheat–rye translocation lines and identify genome-specific transcripts, we developed a custom Roche NimbleGen Gene Expression microarray that contains probes derived from the sequence of hexaploid wheat, diploid rye and diploid progenitors of hexaploid wheat genome (Lee et al., 2014. Using the array developed, we identified genome-specific transcripts in a wheat–rye translocation line (Lee et al., 2014. Expression data are deposited in the NCBI Gene Expression Omnibus (GEO under accession number GSE58678. Here we report the details of the methods used in the array workflow and data analysis.

    Cover cropping is a prevalent conservation practice that offers substantial benefits to soil and water quality. However, winter cereal cover crops preceding corn may diminish beneficial rotation effects because two grass species are grown in succession. Here, we show that rye cover crops host pathogens capable of causing corn seedling disease. We isolated Fusarium graminearum, F. oxysporum, Pythium sylvaticum, and P. torulosum from roots of rye and demonstrate their pathogenicity on corn seedlings. Over 2 years, we quantified the densities of these organisms in rye roots from several field experiments and at various intervals of time after rye cover crops were terminated. Pathogen load in rye roots differed among fields and among years for particular fields. Each of the four pathogen species increased in density over time on roots of herbicide-terminated rye in at least one field site, suggesting the broad potential for rye cover crops to elevate corn seedling pathogen densities. The radicles of corn seedlings planted following a rye cover crop had higher pathogen densities compared with seedlings following a winter fallow. Management practices that limit seedling disease may be required to allow corn yields to respond positively to improvements in soil quality brought about by cover cropping.

    Rye sourdough breads go stale more slowly than wheat breads. To understand the peculiarities of bread staling, rye sourdough bread, wheat bread, and a number of starches were studied using wide-angle X-ray diffraction, nuclear magnetic resonance ((13)C CP MAS NMR, (1)H NMR, (31)P NMR), polarized light microscopy, rheological methods, microcalorimetry, and measurement of water activity. The degree of crystallinity of starch in breads decreased with hydration and baking to 3% and increased during 11 days of storage to 21% in rye sourdough bread and to 26% in wheat bread. (13)C NMR spectra show that the chemical structures of rye and wheat amylopectin and amylose contents are very similar; differences were found in the starch phospholipid fraction characterized by (31)P NMR. The (13)C CP MAS NMR spectra demonstrate that starch in rye sourdough breads crystallize in different forms than in wheat bread. It is proposed that different proportions of water incorporation into the crystalline structure of starch during staling and changes in starch fine structure cause the different rates of staling of rye and wheat bread.

    In the early 20th century, the British anthropologist Melville William Hilton-Simpson (1881-1938) did explorations in Africa, mainly the Congo region and the Aurès region in Algeria. He showed considerable interest in local medicinal practices and plants used by the natives, mainly the Algerian Berbers. He left notes, letters and publications about traditional medicine which were screened for relevant information about medicinal plant use. His reports were compared with current knowledge and recent study results. Many plants described by Hilton-Simpson as therapeutically relevant could prove their efficacy in current studies which again shows that historical sources may exert some reliability. The study, however, unveiled a couple of plants reported as traditionally used, but neglected by modern science so far. These, including Marrubium supinum, Cynoglossum pictum (= C. creticum), Sonchus maritimus, and two Erodium species, are strongly recommended to be further studied. Foresightedly, this approach was already intended by Hilton-Simpson himself.

  7. Quality evaluation of the sourdough rye breads

    2011-12-01

    Full Text Available Sourdough fermentation is a biotechnological process that has been reported to improve dough properties, to increase bread flavor and taste, to enhance nutritional value and to extend shelf life of sourdough bread. The quality of rye breads prepared with 20 and 40% sourdough, fermented with different mixed starter cultures was investigated in this study. The bread quality was evaluated in terms of specific volume, humidity, total titratable acidity, crumb characteristics and sensory profiles. Digital image analysis revealed that rye bread with 40% sourdough had a considerably denser crumb structure. Rye bread with 20% sourdough maintained superior texture characteristics over the storage period, while increasing the sourdough content to 40% had a negative effect on the texture. The sensory profiles of the bread highly depended on the type of starter cultures used for fermentation.

    Prominent normal faults occur within and around Long Valley caldera, in the eastern Sierra Nevada of California. However, their relationship to both the magmatic and tectonic evolution of the caldera since the 760 ka eruption of the Bishop Tuff remains poorly understood. In particular, in the Mono-Inyo Craters north of Long Valley, extensional faulting appears to be replaced by dike intrusion where magma is available in the crust. However, it is unclear whether extensional faults in Long Valley caldera have been active since the eruption of the Bishop Tuff (when the current topography was established) or are a relatively young phenomenon owing to the cooling and crystallization of the Long Valley magma reservoir. Here we use GPS geodesy and geomorphology to investigate the evolution of the Hilton Creek fault, the primary range-front fault bounding Long Valley caldera to the southwest. Our primary goals are to determine how long the Hilton Creek fault has been active and whether slip rates have been constant over that time interval. To characterize the modern deformation field, we capitalize on recently (July, 2010) reoccupied GPS benchmarks first established in 1999-2000. These fixed-array GPS data show no discernible evidence for recent slip on the Hilton Creek fault, which further highlights the need for longer-term constraints on fault motion. To establish a fault slip history, we rely on a suite of five prominent shorelines from Pleistocene Long Valley Lake whose ages are well constrained based on field relationships to dated lavas, and that are tilted southward toward the Hilton Creek fault. A preliminary analysis of shoreline orientations using GPS surveys and a 5-m-resolution Topographic Synthetic Aperture Radar (TOPSAR) digital elevation model shows that lake shorelines tilt towards the Hilton Creek fault at roughly parallel gradients (~ 0.6%). The measured shorelines range in inferred age from 100 ka to 500 ka, which constrain recent slip on the Hilton

    Full Text Available Selection of an appropriate sowing time for some winter rye (Secale cereale cultivars could reduce the need for crop protection measures. In this study the occurrence and status of pests and weeds in relation to sowing time and growth habit of winter rye was studied in southern Finland. This was done using three sowing times and four rye varieties in field trials conducted at three locations in 1999–2001. The early sown rye was severely affected by pests (Oscinella frit, Mayetiola destructor and weeds, whereas postponing sowing for two weeks after the recommended sowing time in late August resulted in considerably less damage and the optimal establishment of crop stands. The German hybrid varieties Picasso and Esprit produced more tillers m-2 in autumn than the Finnish varieties Anna and Bor 7068. However, the number of pests and weeds did not differ among rye varieties. Late sowing of rye should be considered to minimize the need for plant protection. If rye is sown at the recommended time it may still require insecticide treatments promptly in the autumn whereas herbicide treatment need not be determined until spring, after recording the winter mortality of weeds.;

    Rye (Secale cereale L.) is an important cover crop that provides many benefits to cropping systems including weed and pest suppression resulting from allelopathic substances. Hydroxamic acids have been identified as allelopathic compounds in rye. This research was conducted to improve the methodology for quantifying hydroxamic acids and to determine the relationship between hydroxamic acid content and phytotoxicity of extracts of rye root and shoot tissue harvested at selected growth stages. Detection limits for an LC/MS-MS method for analysis of hydroxamic acids from crude aqueous extracts were better than have been reported previously. (2R)-2-beta-D-Glucopyranosyloxy-4-hydroxy-(2H)-1,4-benzoxazin-3(4H)-one (DIBOA-G), 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one (DIBOA), benzoxazolin-2(3H)-one (BOA), and the methoxy-substituted form of these compounds, (2R)-2-beta-D-glucopyranosyloxy-4-hydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one (DIMBOA glucose), 2,4-hydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one (DIMBOA), and 6-methoxy-benzoxazolin-2(3H)-one (MBOA), were all detected in rye tissue. DIBOA and BOA were prevalent in shoot tissue, whereas the methoxy-substituted compounds, DIMBOA glucose and MBOA, were prevalent in root tissue. Total hydroxamic acid concentration in rye tissue generally declined with age. Aqueous crude extracts of rye shoot tissue were more toxic than extracts of root tissue to lettuce (Lactuca sativa L.) and tomato (Lycopersicon esculentum Mill.) root length. Extracts of rye seedlings (Feekes growth stage 2) were most phytotoxic, but there was no pattern to the phytotoxicity of extracts of rye sampled at growth stages 4 to 10.5.4, and no correlation of hydroxamic acid content and phytotoxicity (I50 values). Analysis of dose-response model slope coefficients indicated a lack of parallelism among models for rye extracts from different growth stages, suggesting that phytotoxicity may be attributed to compounds with different modes of action at

    Full Text Available Biogas production in the Czech Republic has expanded substantially, including marginal regions for maize cultivation. Therefore, there are increasingly sought materials that could partially replace maize silage, as a basic feedstock, while secure both biogas production and its quality.Two samples of rye grass (Lolium multiflorum var. westerwoldicum silage with different solids content 21% and 15% were measured for biogas and methane yield. Rye grass silage with solid content of 15% reached an average specific biogas yield 0.431 m3·kg−1 of organic dry matter and an average specific methane yield 0.249 m3·kg−1 of organic dry matter. Rye grass silage with solid content 21% reached an average specific biogas yield 0.654 m3·kg−1 of organic dry matter and an average specific methane yield 0.399 m3·kg−1 of organic dry matter.

    Highlights: • Rye straw ash has a high sintering tendency at elevated temperatures. • Addition of additive increases melting temperature of the rye straw ash. • Kaolin addition leads to formation of silicates binding K in the ash. • Calcite and Ca-sludge promotes formation of silicates and phosphates in the ash. • Calcite addition restrains attaching and accumulation of rye straw ash melts. - Abstract: The understanding of ash sintering during combustion of agricultural residues is far from complete, because of the high heterogeneity of the content and composition of ash forming matters and the complex transformation of them. In order to make agricultural residues competitive fuels on the energy market, further research efforts are needed to investigate agricultural residues’ ash sintering behavior and propose relevant anti-sintering measures. The aim of this work was to investigate the ash characteristics of rye straw and effects of additives. Three additives were studied regarding their abilities to prevent and abate rye straw ash sintering. Standard ash fusion characterization and laboratory-scale sintering tests were performed on ashes from mixtures of rye straw and additives produced at 550 °C. Ash residues from sintering tests at higher temperatures were analyzed using a combination of X-ray diffraction (XRD) and scanning electron microscopy–energy dispersive X-ray spectrometry (SEM–EDX). High sintering and melting tendency of the rye straw ash at elevated temperatures was observed. Severe sintering of the rye straw ash was attributed to the formation and fusion of low temperature K–silicates and K–phosphates with high K/Ca ratios. Among the three additives, calcite served the best one to mitigate sintering of the rye straw ash. Ca from the calcite promoted formation of high temperature silicates and calcium rich K–phosphates. In addition, calcite may hinder aggregating of ash melts and further formation of large ash slag. Therefore

    Full Text Available Winter rye (Secale cereale L. is used as a cover crop because of the weed suppression potential of its mulch. To gain insight into the more effective use of rye as a cover crop we assessed changes in benzoxazinone (BX levels in rye shoot tissue over the growing season. Four rye varieties were planted in the fall and samples harvested at intervals the following spring. Two different measures of phytotoxic compound content were taken. Seed germination bioassays were used as an estimate of total phytotoxic potential. Dilutions of shoot extracts were tested using two indicator species to compare the relative toxicity of tissue. In addition, BX (DIBOA, DIBOA-glycoside, and BOA levels were directly determined using gas chromatography. Results showed that rye tissue harvested in March was the most toxic to indicator species, with toxicity decreasing thereafter. Likewise the BX concentration in rye shoot tissue increased early in the season and then decreased over time. Thus, phytotoxicity measured by bioassay and BX levels measured by GC have a similar but not identical temporal profile. The observed decrease in phytotoxic potential and plant BX levels in rye later in the season appears to correlate with the transition from vegetative to reproductive growth.

    Full Text Available The modern biotechnology of bread production uses sourdough as a natural leavening agent. In rye bread making the sourdough is essential. The aim of this paper was to examine the influence of starter culture types, flour extraction rate, dough yield and temperature of fermentation on the quality of the sourdough rye bread. The sourdough was prepared using a mixed culture of Lactobacillus plantarum and Lactobacillus brevis. The rye breads prepared with 20% sourdough and bread with no sourdough were investigated. The addition of sourdough increases the loaf specific volume relative to control sample. The best results were obtained in case of sourdough made from dark rye flour, 300 dough yield, after 24 h fermentation at 30 °C. The porosity of the bread was estimated by analyzing the scanned images of the vertically halved bread. Digital image analysis revealed that the cell-to-total area ratio was lower for the sourdough prepared with whole rye bread.

  18. Increased Risk of Insect Injury to Corn Following Rye Cover Crop.

    2016-08-01

    Decreased pest pressure is sometimes associated with more diverse agroecosystems, including the addition of a rye cover crop (Secale cereale L.). However, not all pests respond similarly to greater vegetational diversity. Polyphagous pests, such as true armyworm (Mythimna unipuncta Haworth), black cutworm (Agrotis ipsilon Hufnagel), and common stalk borer (Papaipema nebris Guenee), whose host range includes rye have the potential to cause injury to crops following a rye cover crop. The objectives of this study were to compare the abundance of early-season insect pests and injury to corn (Zea mays L.) from fields with and without a rye cover crop on commercial farms. Fields were sampled weekly to quantify adult and larval pests and feeding injury to corn plants from mid-April until corn reached V8 stage, during 2014 and 2015. Measurements within fields were collected along transects that extended perpendicularly from field edges into the interior of cornfields. Adult true armyworm and adult black cutworm were captured around all cornfields, but most lepidopteran larvae captured within cornfields were true armyworm and common stalk borer. Cornfields with a rye cover crop had significantly greater abundance of true armyworm and greater proportion of injured corn. Both true armyworm abundance and feeding injury were significantly greater in the interior of cornfields with rye. Common stalk borer abundance did not differ between cornfields with or without rye cover. Farmers planting corn following a rye cover crop should be aware of the potential for increased presence of true armyworm and for greater injury to corn. © The Authors 2016.

    Rye straw, a very low-cost material, was employed as a biosorbent for two organic water-soluble dyes belonging to different dye classes, namely acridine orange (acridine group) and methyl green (triarylmethane group). The adsorption properties were tested for native and citric acid–NaOH modified rye straw, both in nonmagnetic and magnetic versions. The adsorption equilibrium was reached in 2 h and the adsorption isotherms data were analyzed using the Langmuir model. The highest values of maximum adsorption capacities were 208.3 mg/g for acridine orange and 384.6 mg/g for methyl green. - Highlights: • Rye derivatives can be considered as efficient adsorbents for organic dyes. • Magnetic modification of straw by microwave-synthesized magnetic iron oxides. • Citric acid–NaOH modification increased the maximum adsorption capacities.

    The analysis of early generations of triticale showed numerous rearrangements of the genome. Complexed transformation included loss of chromosomes, t-heterochromatin content changes and the emergence of retrotransposons in new locations. This study investigated certain aspects of genomic transformations in the early generations (F5 and F8) of the primary octoploid triticale derived from the cross of hexaploid wheat with the diploid rye. Most of the plants tested were hypoploid; among eliminated chromosomes were rye chromosomes 4R and 5R and variable number of wheat chromosomes. Wheat chromosomes were eliminated to a higher extent. The lower content of telomeric heterochromatin was also found in rye chromosomes in comparison with parental rye. Studying the location of selected retrotransposons from Ty1-copia and Ty3-gypsy families using fluorescence in situ hybridization revealed additional locations of these retrotransposons that were not present in chromosomes of parental species. ISSR, IRAP and REMAP analyses showed significant changes at the level of specific DNA nucleotide sequences. In most cases, the disappearance of certain types of bands was observed, less frequently new types of bands appeared, not present in parental species. This demonstrates the scale of genome rearrangement and, above all, the elimination of wheat and rye sequences, largely due to the reduction of chromosome number. With regard to the proportion of wheat to rye genome, the rye genome was more affected by the changes, thus this study was focused more on the rye genome. Observations suggest that genome reorganization is not finished in the F5 generation but is still ongoing in the F8 generation.

    Full Text Available the article has evaluation of four years observation of the prospective varieties of winter rye Yantarnaya in comparison with the standard in the nursery of the competitive variety trial of the Ural Scientific Research Institute for Agriculture in Yekaterinburg and the results of a two year test in the system of FGBU «Gossortkomissiya». A winter rye is widely used for bread baking mainly. This culture has resistance from negative environmental factors. The main cause of limited use of a winter rye grain for forage is high content water-soluble pentosans over 1.5%. They reduce availability of nutrients to an organism. Creation of varieties with low content of water-soluble pentosans is the rational solution of increase in use of parts of grain of a winter rye in forage production. Together with VIR, a variety with the required characteristics was transferred to the state grade testing. The observation took place in 2013–2017, with contrasts on the weather conditions. According to FGBU «Gossorgkomissiya», the variety has high potential productivity and significantly exceeds same low pentosan variety in the yield.

    Sourdough fermentation by lactic acid bacteria is commonly used in bread baking, affecting several attributes of the final product. We analyzed whole-grain wheat and rye breads and doughs prepared with baker's yeast or a sourdough starter including Candida milleri, Lactobacillus brevis and Lactobacillus plantarum using non-targeted metabolic profiling utilizing LC-QTOF-MS. The aim was to determine the fermentation-induced changes in metabolites potentially contributing to the health-promoting properties of whole-grain wheat and rye. Overall, we identified 118 compounds with significantly increased levels in sourdough, including branched-chain amino acids (BCAAs) and their metabolites, small peptides with high proportion of BCAAs, microbial metabolites of phenolic acids and several other potentially bioactive compounds. We also identified 69 compounds with significantly decreased levels, including phenolic acid precursors, nucleosides, and nucleobases. Intensive sourdough fermentation had a higher impact on the metabolite profile of whole-grain rye compared to milder whole-grain wheat sourdough fermentation. We hypothesize that the increased amount of BCAAs and potentially bioactive small peptides may contribute to the insulin response of rye bread, and in more general, the overall protective effect against T2DM and CVD.

    Rye was sown in pots imbeded into the ground, in non-competitive conditions. Plot differed only with kinds of ground surfaces (grass, bare soil) which affected the spectral composition of reflected sunlight. Plants growing on the ground covered with grass received more radiation in the range of far red than plants growing on bare soil. The plants from both plots reacted differently to the environmental conditions by creating different habits. Main shoots of rye growing in the neighbourhood of grass had been much taller than the rye growing on the bare soil; its internodes were longer and its heads heavier and heads had more grain

    Full Text Available Modern nutrition and nutritionists worldwide more and more require high nutritional quality foods including breads. Products based on rye (Secale cereale L. and other cereals such as buckwheat (Fagopyrum esculentum Moench provide nutritional benefits such as higher intake of fibre which has a positive effect on digestion and decreases a risk of obesity and heart disease, therefore current trend is to replace part of gluten breads with other cereal products. The main aim of this work was to observe changes in breads based on buckwheat and rye mixtures influenced by ratio of buckwheat and rye flour. Eleven ratios of buckwheat-rye flours were prepared. Dough and bread quality were tested in terms of dough machine workability, dough and pastry yield, baking loss, specific volume and texture analyses 24 and 72 hours after baking. The results were statistically evaluated and showed that rising amount of rye flour in mixtures did not affect dough machine workability but improved all of the investigated texture characteristics such as chewiness and gumminess, concerning specific volume of breads, no significant differences were found. All texture parameters deteriorated with staling time.

    The changes in molecular mass of arabinoxylan (AX) and protein caused by bread baking process were examined using a model rye bread. Instead of the normal flour, the dough contained starch, water-extractable AX and protein which were isolated from rye wholemeal. From the crumb of selected model breads, starch was removed releasing AX-protein complexes, which were further examined by size exclusion chromatography. On the basis of the research, it was concluded that optimum model mix can be composed of 3-6% AX and 3-6% rye protein isolate at 94-88% of rye starch meaning with the most similar properties to low extraction rye flour. Application of model rye bread allowed to examine the interactions between AX and proteins. Bread baked with a share of AX, rye protein and starch, from which the complexes of the highest molar mass were isolated, was characterized by the strongest structure of the bread crumb.

    Rye genetic resources provide a valuable source of new alleles for the improvement of frost tolerance in rye breeding programs. Frost tolerance is a must-have trait for winter cereal production in northern and continental cropping areas. Genetic resources should harbor promising alleles for the improvement of frost tolerance of winter rye elite lines. For frost tolerance breeding, the identification of quantitative trait loci (QTL) and the choice of optimum genome-based selection methods are essential. We identified genomic regions involved in frost tolerance of winter rye by QTL mapping in a biparental population derived from a highly frost tolerant selection from the Canadian cultivar Puma and the European elite line Lo157. Lines per se and their testcrosses were phenotyped in a controlled freeze test and in multi-location field trials in Russia and Canada. Three QTL on chromosomes 4R, 5R, and 7R were consistently detected across environments. The QTL on 5R is congruent with the genomic region harboring the Frost resistance locus 2 (Fr-2) in Triticeae. The Puma allele at the Fr-R2 locus was found to significantly increase frost tolerance. A comparison of predictive ability obtained from the QTL-based model with different whole-genome prediction models revealed that besides a few large, also small QTL effects contribute to the genomic variance of frost tolerance in rye. Genomic prediction models assigning a high weight to the Fr-R2 locus allow increasing the selection intensity for frost tolerance by genome-based pre-selection of promising candidates.

    Fluorescent in situ hybridization (FISH) was utilized to monitor the level of ionizing radiation ( 60 Co source) in their ability to cause intra- and intergeneric chromosomal aberrations in triticale seeds. Seeds were irradiated with 0, 20, 50, 100, 200, 300, 400, 500 and 1000 Gy doses. The root growth of irradiated seeds was greatly inhibited at 200 Gy and above. Various types of aberrations including wheat-rye, wheat-wheat, rye-rye, wheat-rye-wheat, rye-wheat-rye translocations and acentric fragments with or without translocations were observed. There was a consistent increase in proportion of aberrations per cell with an increase in radiation dose. It was concluded that for an optimal level of chromosomal translocation and least number of acentric fragments, a 20 Gy dose was quite sufficient for inducing a desirable level of wheat-rye chromosomal translocations. The excellent efficiency and importance of utilizing FISH in such studies of alien-introgression via chromosomal translocations are discussed. (author)

    The effect of rye flour extraction rates and baking on thiamine and riboflavin content, and antioxidant capacity of traditional rye bread were studied and compared with white wheat flour. The content of thiamine was higher (10.9%) in rye dough formulated with dark rye flour (F-100%; extraction rate of 100%) than in rye dough formulated with brown rye flour (F-92%; extraction rate of 92%) that was similar to dough made with wheat flour. The riboflavin content in rye dough made from flour F-100% was also higher (16%) than in dough formulated with flour F-92%, and both provided larger riboflavin content than wheat dough. Baking led to reductions in thiamine of 56% for wheat bread and of 20% for both rye breads; however, this process caused only a 10% decrease in riboflavin for wheat bread and a 30% decrease for rye breads. Trolox equivalent antioxidant capacity, peroxyl radical scavenging capacity, DPPH radical scavenging activity, and Folin-Ciocalteu reducing capacity were higher in rye than in wheat dough and bread. Baking process produced slight changes in antioxidant activity, except for Superoxide Dismutase-like activity where a sharp decrease was observed. Our findings showed that rye breads are an important source of B vitamins and rye breads formulated with dark and brown flours showed better antioxidant properties than wheat bread. Therefore, rye breads should be more widely recommended in human nutrition.

    Rye bran was used as a fat substitute in the production of meatballs. The effect of rye bran addition on the fatty acid composition, trans fatty acids, total fat, some physico-chemical and sensory properties of the samples was studied. Meatballs were produced with four different formulations including 5%, 10%, 15% and 20% rye bran addition. Control samples were formulated with 10% fat addition. Meatballs containing rye bran had lower concentrations of total fat and total trans fatty acids than the control samples. Meatballs made with addition of 20% rye bran had the highest protein, ash contents, L value (lightness), b value (yellowness), and the lowest moisture, salt content and weight losses and a value (redness). There was a significant difference among the meatball samples in respect to sensory properties and 5%, 10% rye bran added meatballs and control samples had high acceptability.

  19. Allelopathic cover crop of rye for integrated weed control in sustainable agroecosystems

    Directory of Open Access Journals (Sweden)

    Vincenzo Tabaglio

    2013-02-01

    Full Text Available The allelopathic potential of rye (Secale cereale L. is mainly due to phytotoxic benzoxazinones, compounds that are produced and accumulated in young tissues to different degrees depending on cultivar and environmental influences. Living rye plants exude low levels of benzoxazinones, while cover crop residues can release from 12 to 20 kg ha–1. This paper summarizes the results obtained from several experiments performed in both controlled and field environments, in which rye was used as a cover crop to control summer weeds in a following maize crop. Significant differences in benzoxazinoid content were detected between rye cultivars. In controlled environments, rye mulches significantly reduced germination of some broadleaf weeds. Germination and seedling growth of Amaranthus retroflexus and Portulaca oleracea were particularly affected by the application of rye mulches, while Chenopodium album was hardly influenced and Abutilon theophrasti was advantaged by the presence of the mulch. With reference to the influence of agronomic factors on the production of benzoxazinoids, nitrogen fertilization increased the content of allelochemicals, although proportionally less than dry matter. The field trial established on no-till maize confirmed the significant weed suppressiveness of rye mulch, both for grass and broadleaf weeds. A significant positive interaction between nitrogen (N fertilization and notillage resulting in the suppression of broadleaf weeds was observed. The different behavior of the weeds in the presence of allelochemicals was explained in terms of differential uptake and translocation capabilities. The four summer weeds tested were able to grow in the presence of low amounts of benzoxazolin-2(3H-one (BOA, between 0.3 and 20 mmol g–1 fresh weight. Although there were considerable differences in their sensitivity to higher BOA concentrations, P. oleracea, A. retroflexus, and Ch. album represented a group of species with a consistent

    This study investigated the variability of amino acid (AA) digestibility of rye grains in laying hens. Relationships between AA digestibility and physical properties (thousand seed weight, test weight, falling number, and extract viscoelasticity), chemical composition (proximate nutrients, non-starch polysaccharides, AA, minerals, and inositol phosphates), gross energy concentration, and in vitro solubility of nitrogen (N) of the grains were also examined. Twenty rye genotypes were grown under standardised agronomic and environmental conditions as part of a collaborative research project known as "GrainUp". Each genotype was added to a basal diet at 500 g/kg at the expense of maize starch to produce 20 rye diets. The experimental design comprised four Latin Squares (6 × 6) distributed over two runs, resulting in 12 experimental periods. Caecectomised laying hens (LSL-Classic) were individually kept in metabolism cages. Excreta were collected quantitatively for 4 d, and AA digestibility of the rye genotypes was determined using a regression approach. The digestibility of AA was generally low but varied significantly among the 20 rye genotypes, especially for Lys (digestibility range 35-59%), Met (57-75%), Thr (34-54%), and Trp (36-71%). Nevertheless, physical and chemical characteristics as well as the in vitro solubility of N correlated in only a few cases with AA digestibility. Multiple linear regression was used to calculate equations to predict AA digestibility based on the analysed characteristics. However, their explanatory power, as judged by the adjusted R(2), was not sufficiently precise for practical application (below 0.6 for most AA). In conclusion, the AA digestibility of rye grain is generally low and varies significantly between crop genotypes. Equations based on its physical and chemical characteristics are not sufficiently precise to be useful for feed formulation.

    Rye is considered as a potential raw material for starch industry. Starting from a survey of technical procedures of isolating starches from rye-flour and -grits investigations will be reported, which were performed on pilot plant- and laboratory-isolated rye starches. The present paper deals with its granule appearance and composition. A distribution of granule size between small granules ({<=} 10 {mu}m - 15%) and large granules ({>=} 11 ... {<=} 40 {mu}m = 85%) is typical for the totality of the starches. Differing distributions depend on the conditions of isolation: The entity of starch containing samples resulted from the latoratory procedures under investigation. Large-granule starch preparations were isolated in the pilot plant: The centrifuge-overflow contains the small-granule fraction which is high in impurities. Granule crystallinity amounts to 16%. The crystalline component - like in wheat and triticale starches - consists predominantly of A-polymorph - with up to 9% of the B-type. The isotherms of water exchange are of the cereal type. The contents of minor constituents largely relate to the small granule fraction which assembles the majority of crude protein, pentosans and lipids, which are difficult to remove. Lipid components in all fractions influence the results of linear chain-iodine interactions and they must be removed to proceed from apparent to absolute polysaccharide indices. The absolute amylose contents amount to {approx equal} 25% for large granule samples and to 20-21% for small granule samples. The average chain-length of iodine binding helical regions was determined with 220-240 AGU. (orig.).

    To meet the current challenges in human food production, improved understanding of the genetic diversity of crop species that maximizes the selection efficacy in breeding programs is needed. The present study offers new insights into the diversity, genetic structure and demographic history of cultivated rye (Secale cereale L.). We genotyped 620 individuals from 14 global rye populations with a different end use (grain or forage) at 32 genome-wide simple sequence repeat markers. We reveal the relationships among these populations, their sizes and the timing of domestication events using population genetics and model-based inference with approximate Bayesian computation. Our main results demonstrate (i) a high within-population variation and genetic diversity, (ii) an unexpected absence of reduction in diversity with an increasing improvement level and (iii) patterns suggestive of multiple domestication events. We suggest that the main drivers of diversification of winter rye are the end use of rye in two early regions of cultivation: rye forage in the Mediterranean area and grain in northeast Europe. The lower diversity and stronger differentiation of eastern European populations were most likely due to more intensive cultivation and breeding of rye in this region, in contrast to the Mediterranean region where it was considered a secondary crop or even a weed. We discuss the relevance of our results for the management of gene bank resources and the pitfalls of inference methods applied to crop domestication due to violation of model assumptions and model complexity. © 2015 John Wiley & Sons Ltd.

    China's urbanization process is unique in having been due to economic systems and migration policies. Towns and townships in rural areas are different from cities in their social and economic characteristics and their structure and function. The urban system in China is initially described with the distinction drawn between cities, "jian-zhi towns", (organic town) which are officially recognized, and rural areas. Analysis is provided f the economic and residential registration status of town residents and migration in northern China. Data were obtained from a 1987 survey of 1314 households in Wongnioute Banner in Inner Mongolia, and a 1985 migration survey of 2089 rural households in 41 villages. The study area was selected because jian-zhi town status was easily obtained and the are needed more towns for local administration and trade; the area was similar in geographic, social, economic, and cultural characteristics to other northern and northwestern regions. The Wongnioute Banner comprises 5 towns (Qiaotou, Wufendi, Hairesu, Wuduentaohai, and Wutonghua) and 1 country town (Wudan). All citizens from birth have an agricultural or nonagricultural status, which can be changed by passing national exams or completing a university education, joining the military and becoming an officer, marrying someone with a nonagricultural status, reunifying the family, or holding a special program. Quotas are set annually for status changes, e.g. in Tibet Autonomous Region the annual quota was 3%. Town residents may have either status. In the sample, 56.6% lived in town and had a nonagricultural status; 17.7% of heads of household town residents had an agricultural status and had stronger ties to villages because of family connections. Commuters are a third group and comprise 8.9%. County towns and jian-zhi towns are grouped the same, but are quite different in population size. Wudan had a population of 27,600 spread over an area of 480 hectares. The jian-zhi towns each had an

    The Hilton Creek Fault (HCF) is a range-bounding extensional fault that forms the eastern escarpment of California's Sierra Nevada mountain range, near the town of Mammoth Lakes. The fault is well mapped along its main trace to the south of the Long Valley Caldera (LVC), but the location and nature of its northern terminus is poorly constrained. The fault terminates as a series of left-stepping splays within the LVC, an area of active volcanism that most notably erupted 760 ka, and currently experiences continuous geothermal activity and sporadic earthquake swarms. The timing of the most recent motion on these fault splays is debated, as is the threat posed by this section of the Hilton Creek Fault. The Third Uniform California Earthquake Rupture Forecast (UCERF3) model depicts the HCF as a single strand projecting up to 12km into the LVC. However, Bailey (1989) and Hill and Montgomery-Brown (2015) have argued against this model, suggesting that extensional faulting within the Caldera has been accommodated by the ongoing volcanic uplift and thus the intracaldera section of the HCF has not experienced motion since 760ka.We intend to map the intracaldera fault splays and model their subsurface characteristics to better assess their rupture history and potential. This will be accomplished using high-resolution topography and subsurface geophysical methods, including ground-based magnetics. Preliminary work was performed using high-precision Nikon Nivo 5.C total stations to generate elevation profiles and a backpack mounted GEM GS-19 proton precession magnetometer. The initial results reveal a correlation between magnetic anomalies and topography. East-West topographic profiles show terrace-like steps, sub-meter in height, which correlate to changes in the magnetic data. Continued study of the magnetic data using Oasis Montaj 3D modeling software is planned. Additionally, we intend to prepare a high-resolution terrain model using structure-from-motion techniques

    Many studies have demonstrated the potential health benefits of consuming more high-fibre cereal-based food products. Therefore, there is a need to discover new ways to improve the overall nutritional balance of refined cereal products and focus on increasing their dietary fibre content, at the expense of readily digestible carbohydrates. Lab-scale milling and sieving of whole rye grain was used to obtain two fractions rich in dietary fibre. The fractions were analysed and compared, in terms of microstructure, chemical com- position and nutritional quality. The two fractions significantly obtained differed in their particle size and contents of minerals, available saccharides, and nutritional fractions of starch and dietary fibre and its major components. The total dietary fibre concentrations in the coarse and fine fractions were 50.0 and 36.0 g/100 g, respectively, i.e. three and 2.2 times higher than that of wholegrain rye flour. Both fractions also differed in their relative proportions of major fibre components. In the fine fraction, the levels of soluble fibre, as well as soluble arabinoxylans and fructans, were significantly higher than those in the coarse fraction. It was shown that the application of a simple dry-fractionation method to wholemeal rye flour allows the preparation of two rye products which can serve as concentrated sources of dietary fibre low in available saccharides.

    Cover crops are beneficial to agroecosystems because they decrease soil erosion and nutrient loss while increasing within-field plant diversity. Greater plant diversity within cropping systems can positively affect beneficial arthropod communities. We hypothesized that increasing plant diversity within annually rotated corn and soybean with the addition of a rye cover crop would positively affect the beneficial ground and canopy-dwelling communities compared with rotated corn and soybean grown without a cover crop. From 2011 through 2013, arthropod communities were measured at two locations in Iowa four times throughout each growing season. Pitfall traps were used to sample ground-dwelling arthropods within the corn and soybean plots and sweep nets were used to measure the beneficial arthropods in soybean canopies. Beneficial arthropods captured were identified to either class, order, or family. In both corn and soybean, community composition and total community activity density and abundance did not differ between plots that included the rye cover crop and plots without the rye cover crop. Most taxa did not significantly respond to the presence of the rye cover crop when analyzed individually, with the exceptions of Carabidae and Gryllidae sampled from soybean pitfall traps. Activity density of Carabidae was significantly greater in soybean plots that included a rye cover crop, while activity density of Gryllidae was significantly reduced in plots with the rye cover crop. Although a rye cover crop may be agronomically beneficial, there may be only limited effects on beneficial arthropods when added within an annual rotation of corn and soybean. © The Authors 2017.

    To compare the effects of regular vs low-FODMAP rye bread on irritable bowel syndrome (IBS) symptoms and to study gastrointestinal conditions with SmartPill ® . Our aim was to evaluate if rye bread low in FODMAPs would cause reduced hydrogen excretion, lower intraluminal pressure, higher colonic pH, different transit times, and fewer IBS symptoms than regular rye bread. The study was a randomized, double-blind, controlled cross-over meal study. Female IBS patients ( n = 7) ate study breads at three consecutive meals during one day. The diet was similar for both study periods except for the FODMAP content of the bread consumed during the study day. Intraluminal pH, transit time, and pressure were measured by SmartPill, an indigestible motility capsule. Hydrogen excretion (a marker of colonic fermentation) expressed as area under the curve (AUC) (0-630 min) was [median (range)] 6300 (1785-10800) ppm∙min for low-FODMAP rye bread and 10 635 (4215-13080) ppm∙min for regular bread ( P = 0.028). Mean scores of gastrointestinal symptoms showed no statistically significant differences but suggested less flatulence after low-FODMAP bread consumption ( P = 0.063). Intraluminal pressure correlated significantly with total symptom score after regular rye bread (ρ = 0.786, P = 0.036) and nearly significantly after low-FODMAP bread consumption (ρ = 0.75, P = 0.052). We found no differences in pH, pressure, or transit times between the breads. Gastric residence of SmartPill was slower than expected. SmartPill left the stomach in less than 5 h only during one measurement (out of 14 measurements in total) and therefore did not follow on par with the rye bread bolus. Low-FODMAP rye bread reduced colonic fermentation vs regular rye bread. No difference was found in median values of intraluminal conditions of the gastrointestinal tract.

    Effects of germination conditions and thermal processes on folate contents of rye were investigated. Total folate contents were determined microbiologically with Lactobacillus rhamnosus (ATCC 7469) as the growth indicator organism, and individual folates were determined by high-performance liquid chromatography after affinity chromatographic purification. Germination increased the folate content by 1.7-3.8-fold, depending on germination temperature, with a maximum content of 250 micro g/100 g dry matter. Hypocotylar roots with their notably high folate concentrations (600-1180 micro g/100 g dry matter) contributed 30-50% of the folate contents of germinated grains. Germination altered the proportions of folates, increasing the proportion of 5-methyltetrahydrofolate and decreasing the proportion of formylated folate compounds. Thermal treatments (extrusion, autoclaving and puffing, and IR and toasting) resulted in significant folate losses. However, folate levels in grains that were germinated and then were heat processed were higher than for native (nongerminated) grains. Opportunities to optimize rye processing to enhance folate levels in rye-based foods are discussed.

    An experiment was conducted to investigate the effects of dietary inclusion of rye, a model ingredient to increase gut viscosity, between 14 and 28 d of age on immune competence-related parameters and performance of broilers. A total of 960 day-old male Ross 308 chicks were weighed and randomly allocated to 24 pens (40 birds per pen), and the birds in every 8 replicate pens were assigned to 1 of 3 experimental diets including graded levels, 0%, 5%, and 10% of rye. Tested immune competence-related parameters were composition of the intestinal microbiota, genes expression in gut tissue, and gut morphology. The inclusion of 5% or 10% rye in the diet (d 14 to 28) resulted in decreased performance and litter quality, but in increased villus height and crypt depth in the small intestine (jejunum) of the broilers. Relative bursa and spleen weights were not affected by dietary inclusion of rye. In the jejunum, no effects on number and size of goblet cells, and only trends on microbiota composition in the digesta were observed. Dietary inclusion of rye affected expression of genes involved in cell cycle processes of the jejunal enterocyte cells, thereby influencing cell growth, cell differentiation and cell survival, which in turn were consistent with the observed differences in the morphology of the gut wall. In addition, providing rye-rich diets to broilers affected the complement and coagulation pathways, which among others are parts of the innate immune system. These pathways are involved in eradicating invasive pathogens. Overall, it can be concluded that inclusion of 5% or 10% rye to the grower diet of broilers had limited effects on performance. Ileal gut morphology, microbiota composition of jejunal digesta, and gene expression profiles of jejunal tissue, however, were affected by dietary rye inclusion level, indicating that rye supplementation to broiler diets might affect immune competence of the birds. © 2017 Poultry Science Association Inc.

Rye is cultivated as a forage or cover crop and overlaps with a significant portion of wheat acreage in the U.S. northern Great Plains; however, it is not known whether the rye crop influences the evolution of PTR races. We evaluated a global collection of 211 rye accessions against tan spot and assessed the diversity in PTR population on rye in South Dakota. All the rye genotypes were inoculated with PTR races 1 and 5, and infiltrated with Ptr ToxA and Ptr ToxB, at seedling stage. We observed 21% of the genotypes exhibited susceptibility to race 1, whereas, 39% were susceptible to race 5. All 211 accessions were insensitive to both the Ptr toxins. It indicates that though rye exhibits diversity in reaction to tan spot, it lacks Ptr ToxA and ToxB sensitivity genes. This suggests that unknown toxins or other factors can lead to PTR establishment in rye. We characterized the race structure of 103 PTR isolates recovered from rye in South Dakota. Only 22% of the isolates amplified Ptr ToxA gene and were identified as race 1 based on their phenotypic reaction on the differential set. The remaining 80 isolates were noted to be race 4. Our results show that races 1 and 4 are prevalent on rye in South Dakota with a higher frequency of race 4, suggesting a minimal role of rye in the disease epidemiology.

    2016-02-01

    The role of water extractable arabinoxylan with varying molar mass and structure (cross-linked vs. hydrolyzed) in the structure formation of rye bread was examined using a model bread. Instead of the normal flour, the dough contained starch, arabinoxylan and protein, which were isolated from rye wholemeal. It was observed that the applied mixes of these constituents result in a product closely resembling typical rye bread, even if arabinoxylan was modified (by cross-linking or hydrolysis). The levels of arabinoxylan required for bread preparation depended on its modification and mix composition. At 3% protein, the maximum applicable level of poorly soluble cross-linked arabinoxylan was 3%, as higher amounts of this preparation resulted in an extensively viscous dough and diminished bread volume. On the other hand highly soluble, hydrolyzed arabinoxylan could be used at a higher level (6%) together with larger amounts of rye protein (3% or 6%). Further addition of arabinoxylan leads to excessive water absorption, resulting in a decreased viscosity of the dough during baking and insufficient gas retention. Copyright © 2015 Elsevier Ltd.

    Wheat-rye addition and substitution lines and their self progenies revealed variations in telomeric heterochromatin and centromeres. Furthermore, a mitotically unstable dicentric chromosome and stable multicentric chromosomes were observed in the progeny of a Chinese Spring-Imperial rye 3R addition line. An unstable multicentric chromosome was found in the progeny of a 6R/6D substitution line. Drastic variation of terminal heterochromatin including movement and disappearance of terminal heterochromatin occurred in the progeny of wheat-rye addition line 3R, and the 5RS ditelosomic addition line. Highly stable minichromosomes were observed in the progeny of a monosomic 4R addition line, a ditelosomic 5RS addition line and a 6R/6D substitution line. Minichromosomes, with and without the FISH signals for telomeric DNA (TTTAGGG)n, derived from a monosomic 4R addition line are stable and transmissible to the next generation. The results indicated that centromeres and terminal heterochromatin can be profoundly altered in wheat-rye hybrid derivatives. Copyright © 2013. Published by Elsevier Ltd.

    A mining impacted cropland was studied in order to assess its As pollution level and the derived environmental and health risks. Profile soil samples (0–50 cm) and rye plant samples were collected at different distances (0–150 m) from the near mine dump and analyzed for their As content and distribution. These cropland soils were sandy, acidic and poor in organic matter and Fe/Al oxides. The soil total As concentrations (38–177 mg kg{sup −1}) and, especially, the soil soluble As concentrations (0.48–4.1 mg kg{sup −1}) importantly exceeded their safe limits for agricultural use of soils. Moreover, the soil As contents more prone to be mobilized could rise up to 25–69% of total As levels as determined using (NH{sub 4}){sub 2}SO{sub 4}, NH{sub 4}H{sub 2}PO{sub 4} and (NH{sub 4}){sub 2}C{sub 2}O{sub 4}·H{sub 2}O as sequential extractants. Arsenic in rye plants was primarily distributed in roots (3.4–18.8 mg kg{sup −1}), with restricted translocation to shoots (TF = 0.05–0.26) and grains (TF = < 0.02–0.14). The mechanism for this excluder behavior should be likely related to arsenate reduction to arsenite in roots, followed by its complexation with thiols, as suggested by the high arsenite level in rye roots (up to 95% of the total As content) and the negative correlation between thiol concentrations in rye roots and As concentrations in rye shoots (| R | = 0.770; p < 0.01). Accordingly, in spite of the high mobile and mobilizable As contents in soils, As concentrations in rye above-ground tissues comply with the European regulation on undesirable substances in animal feed. Likewise, rye grain As concentrations were below its maximum tolerable concentration in cereals established by international legislation. - Highlights: • Environmental assessment of a rye cultivated area impacted by past mining activities. • Soil As contents exceeded the recommended safe limits for agricultural use of soils. • Soil soluble As concentrations attained high

Display Omitted - Highlights: • Biogas improvement by co-digestion of wheat and rye bread. • Increased population density at high organic loading rates. • Less Pelotomaculum but increased numbers of Syntrophobacter and Smithella found in rye bread reactor. • Replacement of Methanosarcinales by acetate-oxidizers in rye bread co-digestion. • Increasing proportion of Methanomicrobiales in biowaste + rye bread reactor. - Abstract: Acidification of wheat bread (WBS), rye bread (RBS) and fresh biowaste suspensions (FBS), leading to lactate+acetate, lactate+acetate+n-buyrate, and acetate+propionate+n-butyrate, respectively, and biogas production as well as population dynamics were investigated. Co-fermentation of FBS (14 kg m −3 d −1 organic loading rate (OLR)) with WBS or RBS was stable up to an OLR of 22 kg m −3 d −1 and resulted in up to 3 times as much biogas. During co-fermentation at more than 20 kg m −3 d −1 OLR the total population increased more than 2-fold, but the originally low share of propionate-oxidizing bacteria significantly decreased. The proportion of methanogens also decreased. Whereas the proportion of Methanosarcinales to Methanomicrobiales in biowaste and biowaste+WBS remained constant, Methanosarcinales and in particular Methanosaeta spec. in the biowaste+RBS assay almost completely disappeared. Methanomicrobiales increased instead, indicating propionate oxidation via acetate cleavage to CO 2 and hydrogen

    The balance of the labelled 15 N nitrogen fertilizers in lysimentric experiment carried oUt in the turf-podsolic medium loamy soil has been studied. The results of two year experiment (1976-1977) have shown that depending on the doses and time of introduction the use of fertilizer nitrogen by maize varied from 51 to 58 % and by winter rye from 52 to 59 %. Consolidation in the organic substance of soil constituted 18-26 and 17-33 %, respectively. The losses of fertilizer nitrogen varied (14-29 % under maize and 9-23 % under winter rye). Nitrogen losses as a result of atmospheric precipitation infiltration both under maize and winter rye occured mainly at the expense of nitrogen of soil and reached considerable dimensions (31 kg) only under conditions of exceeding moistening of 1976. The losses of fertilizer nitrogen caused by washing out do not exceed 1 % for two years. The main losses of fertilizer nitrogen occurred in the form of gaseous nitrogen compounds

    Full Text Available Present study aims to testify usefulness of particular rye SSR markers for the detection of genetic diversity degree in the set of 20 triticale cultivars coming from different European countries. For this purpose, a set of six rye SSR markers were used. The set of six polymorphic markers provided 22 alleles with an average frequency of 3.67 alleles per locus. The number of alleles ranged between 2 (SCM43 and 5 (SCM28, SCM86. Resulting from the number and frequency of alleles diversity index (DI, polymorphic information content (PIC and probability of identity (PI were calculated. An average value of PIC for 6 SSR markers was 0.505, the highest value was calculated for rye SSR marker SCM86 (0.706. Based on UPGMA algorithm, a dendrogram was constructed. In dendrogram cultivars were divided into two main clusters. The first cluster contained two cultivars, Russian cultivar Greneder and Slovak cultivar Largus, and second included 18 cultivars. Genetically the closest were two Greek cultivars (Niobi and Thisbi and were close to other Greek cultivar Vrodi. It was possible to separate triticale cultivars of spring and winter form in dendrogram. Results showed the utility of rye microsatellite markers for estimation of genetic diversity of European triticale genotypes leading to genotype identification.

    In areas with intensive farming, as in Denmark, it is of great interest to identify possible countermeasures to be taken in order to reduce the longterm effects of radioactive contamination of arable land. The most important longer-lived radionuclides from the Chernobyl were 137 Cs and 134 Cs. The aim of the present project was to identify crops with relatively low or high root uptake of these two isotopes. Although such differences may be small, a shift in varieties might be a cost-effective way to reduce collective doses. The experiment was carried out at Risoe National Laboratory in the summer of 1988. The species used were: spring barley (Hordeum vulgare L) varieties: Golf, Apex, Anker, Sila; Perennial rye grass (Lolium perenne L.) varieties: Darbo (early) and Patoro (late); Italian rye-grass (Lolium multiflorum) variety: Prego; and pea (Pisum arvense L.) variety: Bodil. Each crop was grown in two types of soil, a clay-loam and an organic soil. 137 Cs was added to the clay-loam. The organic soil, which was contaminated with 137 Cs from the Chernobyl accident, was supplied with 134 Cs. Sila barley and Italian rye-grass were identified among the species tested as plants with a relative high uptake of radio-caesium. (author)

    Full Text Available Disease infection in relation to sowing time of winter rye (Secale cereale was studied in southern Finland in order to compare overwintering capacity of modern rye varieties and to give recommendations for rye cultivation. This was done by using three sowing times and four rye varieties in field trials conducted at three locations in 1999–2001. The early sown rye (beginning of August was severely affected by diseases caused by Puccinia recondita and Microdochium nivale, whereas postponing sowing for two weeks after the recommended sowing time resulted in considerably less infection. The infection levels of diseases differed among rye varieties. Finnish rye varieties Anna and Bor 7068 were more resistant to snow mould and more winter hardy than the Polish variety Amilo, or the German hybrid varieties Picasso and Esprit. However, Amilo was the most resistant to leaf rust. In the first year snow mould appeared to be the primary cause of winter damage, but in the second year the winter damage was positively correlated with leaf rust. No significant correlation between frit fly infestation and winter damage or disease incidence of snow mould or leaf rust was established. The late sowing of rye (in the beginning of September is recommended in Finland, particularly with hybrid varieties, to minimize the need for chemical plant protection in autumn.;

    Rye is an important and valuable gene resource for wheat improvement. However, due to extensive growing of cultivars with disease resistance genes from short arm of rye chromosome 1R and coevolution of pathogen virulence and host resistance, these cultivars successively lost resistance to pathogens. Identification and deployment of new resistance gene sources in rye are, therefore, of especial importance and urgency. A new wheat-rye line, designated as WR41-1, was produced through distant hybridization and chromosome engineering protocols between common wheat cultivar Xiaoyan 6 and rye cultivar German White. It was proved to be a new wheat-rye T4BL·4RL and T7AS·4RS translocation line using sequential genomic in situ hybridization (GISH), multicolor fluorescence in situ hybridization (mc-FISH), and expressed sequence tag-simple sequence repeat (EST-SSR) marker analysis. WR41-1 showed high levels of resistance to powdery mildew (Blumeria graminis f. sp. tritici, Bgt) pathogens prevalent in China at the adult growth stage and 13 of 23 Bgt isolates tested at the seedling stage. According to its resistant pattern to 23 different Bgt isolates, WR41-1 may possess new gene(s) for resistance to powdery mildew, which differed from previously identified and known powdery mildew genes from rye (Pm7, Pm8, Pm17, and Pm20). In addition, WR41-1 was cytologically stable, had a desirable fertility, and is expected to be useful in wheat improvement.

    A nutrient culture experiment was conducted with cereal species viz., wheat (Triticum aestivum L.) cv. PBW-343), rye (Secale cereale L cv. R-308) and triticale (Triticale octoploide L. cv. DT-46), a hybrid of wheat and rye, to examine the genetic variation in root-exuded acid phosphatase (ACPase) activity and kinetics of 32 Pi-uptake under P deficient condition. The ACPase activity was assayed in the extract (intra-) and on surface (extra-cellular) or root, using p-nitrophenyl phosphate as substrate. Significantly higher ACPase activity was observed in wheat followed by rye and triticale both on the root surface and in root extract. In general, root surface ACPase activity was 2.2-fold higher than that in root extract. A strong correlation (r 2 = 0.87**) between extra and intra-cellular ACPase activity was observed. In terms of kinetic parameters, it was observed that 32 Pi uptake and I max values were significantly higher in rye while C min and K m were lowest compared to wheat and triticale. The dry weights of shoot, root and total plant were significantly higher in rye compared to wheat and triticale. Rye also had higher amount of total plant P content The superiority of rye over wheat and triticale in P uptake was observed mainly due to efficient Pi-uptake system, which needs further studies to ascertain the enhancement of Pi-induced high-affinity P transporter in these cereals.

    Graphical abstract: Volatile fatty acid spectra of acidified WBS, RBS or FBS differ, but methanogenesis is similar. Display Omitted - Highlights: • Biogas improvement by co-digestion of wheat and rye bread. • Increased population density at high organic loading rates. • Less Pelotomaculum but increased numbers of Syntrophobacter and Smithella found in rye bread reactor. • Replacement of Methanosarcinales by acetate-oxidizers in rye bread co-digestion. • Increasing proportion of Methanomicrobiales in biowaste + rye bread reactor. - Abstract: Acidification of wheat bread (WBS), rye bread (RBS) and fresh biowaste suspensions (FBS), leading to lactate+acetate, lactate+acetate+n-buyrate, and acetate+propionate+n-butyrate, respectively, and biogas production as well as population dynamics were investigated. Co-fermentation of FBS (14 kg m{sup −3} d{sup −1} organic loading rate (OLR)) with WBS or RBS was stable up to an OLR of 22 kg m{sup −3} d{sup −1} and resulted in up to 3 times as much biogas. During co-fermentation at more than 20 kg m{sup −3} d{sup −1} OLR the total population increased more than 2-fold, but the originally low share of propionate-oxidizing bacteria significantly decreased. The proportion of methanogens also decreased. Whereas the proportion of Methanosarcinales to Methanomicrobiales in biowaste and biowaste+WBS remained constant, Methanosarcinales and in particular Methanosaeta spec. in the biowaste+RBS assay almost completely disappeared. Methanomicrobiales increased instead, indicating propionate oxidation via acetate cleavage to CO{sub 2} and hydrogen.

    Wholegrain rye has been associated with decreased hunger sensations. This may be partly mediated by colonic fermentation. Sustained consumption of fermentable components is known to change the gut microflora and may increase numbers of saccharolytic bacteria. To investigate the effect of wholegrain rye consumption on appetite and colonic fermentation after a subsequent meal. In a randomized, controlled, three-arm cross-over study, twelve healthy male subjects consumed three iso-caloric evening test meals. The test meals were based on white wheat bread (WBB), wholegrain rye kernel bread (RKB), or boiled rye kernels (RK). Breath hydrogen excretion and subjective appetite sensation were measured before and at 30 min intervals for 3 h after a standardized breakfast in the subsequent morning. After the 3 h, an ad libitum lunch meal was served to assess energy intake. In an in vitro study, RKB and RK were subjected to digestion and 24 h-fermentation in order to study SCFA production and growth of selected saccharolytic bacteria. The test meals did not differ in their effect on parameters of subjective appetite sensation the following day. Ad libitum energy intake at lunch was, however, reduced by 11% (P < 0.01) after RKB and 7% (P < 0.05) after RK compared with after WWB evening meal. Breath hydrogen excretion was significantly increased following RKB and RK evening meals compared with WWB (P < 0.01 and P < 0.05, respectively). Overall, RKB and RK were readily fermented in vitro and exhibited similar fermentation profiles, although total SCFA production was higher for RK compared with RKB (P < 0.001). In vitro fermentation of RKB and RK both increased the relative quantities of Bifidobacterium and decreased Bacteroides compared with inoculum (P < 0.001). The C. coccoides group was reduced after RKB (P < 0.001). Consumption of wholegrain rye products reduced subsequent ad libitum energy intake in young healthy men, possibly mediated by

    Understanding relationships between dietary whole grain and health is hindered by incomplete knowledge of potentially bioactive metabolites derived from these foods. We aimed to discover compounds in urine correlated with changes in amounts of whole grain rye consumption. After a wash-out period, volunteers consumed 48-g whole grain rye foods per day for 4 wk and then doubled their intake for a further 4 wk. Samples of 24-h urines were analyzed by flow infusion electrospray MS followed by supervised multivariate data analysis. Urine samples from participants who reported high intakes of rye flakes, rye pasta, or total whole grain rye products could not be discriminated adequately from their wash-out samples. However, discrimination was seen in urine samples from participants who reported high whole grain sourdough rye bread consumption. Accurate mass analysis of explanatory signals followed by fragmentation identified conjugates of the benzoxazinoid lactam 2-hydroxy-1,4-benzoxazin-3-one and hydroxylated phenyl acetamide derivatives. Statistical validation showed sensitivities of 84-96% and specificities of 70-81% (p values bread consumption. Several potentially bioactive alkaloids have been identified in humans consuming fermented whole grain sourdough rye bread. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The article discusses the development of whipped bakery products enriched with dietary fiber, minerals, vitamins retinol, tocopherol, group, polyunsaturated fatty acids through the use of rye and wheat bran and flour of wholegrain wheat. The main raw material for enrichment whipped bakery products used wheat bran and rye. Choice of rye and wheat bran as supplementation prepared whipped bread is explained not only from the point of view of the rationality of the use of this secondary raw materials, but also its rich vitamin and mineral composition. Wheat bran contain the necessary man of b vitamins, including B1, B2, B6, PP and others. Found provitamin a (carotene and vitamin E (tocopherol. Bran is rich in mineral substances. Among them potassium, magnesium, chromium, zinc, copper, selenium and other trace elements. Thanks to this composition bran are essential dietary product. They are rich in insoluble fiber and can be useful to reduce the risk of developing colon cancer. Rye bran contain dietary fiber, tocopherol E, thiamin B1, Riboflavin B2, Pantothenic acid B5, B4 (choline, nicotinic acid B3, etc. In the bran rich set of microelements and macroelements such as iron, calcium, magnesium, phosphorus, potassium, zinc, iodine, selenium, chromium, etc. the Introduction in the diet, bran rye contribute to the prevention and treatment of atherosclerosis, diabetes and anemia. They restore blood pressure, reduce blood sugar levels and improve the cardiovascular system.

    Wheat bran and rye bran are mostly used as animal feed today, but their high content of dietary fiber and bioactive components are beneficial to human health. Increased use of bran as food raw material could therefore be desirable. However, bran mainly contains unextractable dietary fiber and deteriorates the sensory properties of products. Processing by extrusion could increase the extractability of dietary fiber and increase the sensory qualities of bran products. Wheat bran and rye bran were therefore extruded at different levels of moisture content, screw speed and temperature, in order to find the optimal setting for increased extractability of dietary fiber and positive sensory properties. A water content of 24% for wheat bran and 30% for rye bran, a screw speed of 400 rpm, and a temperature of 130 °C resulted in the highest extractability of total dietary fiber and arabinoxylan. Arabinoxylan extractability increased from 5.8% in wheat bran to 9.0% in extruded wheat bran at those settings, and from 14.6% to 19.2% for rye bran. Total contents of dietary fiber and arabinoxylan were not affected by extrusion. Content of β-glucan was also maintained during extrusion, while its molecular weight decreased slightly and extractability increased slightly. Extrusion at these settings is therefore a suitable process for increasing the use of wheat bran and rye bran as a food raw material. © 2017 Institute of Food Technologists®.

    An improvement of rye is one of the mainstream goals of current breeding. Our study is concerned with the introduction of the tetraploid triticale (ABRR) into the 4x rye (RRRR) using classical methods of distant crossing. One hundred fifty BC1F9 hybrid plants [(4x rye × 4x triticales) × 4x rye] obtained from a backcrossing program were studied. The major aim of this work was to verify the presence of an introgressed A- and B- genome chromatin of triticale in a collection of the 4x rye-tiritcale hybrids and to determine their chromosome compositions. In the present study, karyotypes of the previously reported BC1F2s and BC1F3s were compared with that of the BC1F9 generation as obtained after several subsequent open pollinations. The genomic in situ hybridisation (GISH) allowed us to identify 133 introgression forms in which chromosome numbers ranged between 26 and 32. Using four DNA probes (5S rDNA, 25S rDNA, pSc119.2 and pAs1), the fluorescence in situ hybridisation (FISH) was carried out to facilitate an exact chromosome identification in the hybrid plants. The combination of the multi-colour GISH with the repetitive DNA FISH singled out five types of translocated chromosomes: 2A.2R, 4A.4R, 5A.5R, 5B.5R and 7A.7R among the examined BC1F9s. The reported translocation lines could serve as valuable sources of wheat chromatin suitable for further improvements of rye.

    Full Text Available Abstract Background Rye products have previously been shown to induce comparatively low post-prandial insulin responses; irrespectively of their glycaemic indices (GI. However, the mechanism behind this lowered insulin demand remains unknown. An improved insulin economy might contribute to the benefits seen in epidemiological studies with whole grain diets on metabolic risk factors and weight regulation. The objective of this study was to explore the mechanism for a reduced post-prandial insulin demand with rye products. Methods 12 healthy subjects were given flour based rye products made from endosperm, whole grain or bran, produced with different methods (baking, simulated sour-dough baking and boiling as breakfasts in random order in a cross-over design. White wheat bread (WWB was used as a reference. Blood glucose, serum insulin, plasma ghrelin and subjective satiety were measured during 180 minutes. To evaluate the course of post-meal glycaemia, a measure of the glycaemic profile (GP was introduced defined as the duration for the incremental post-prandial blood glucose response divided with the blood glucose incremental peak (min/mM. Results The study shows that whole grain rye breads and endosperm rye products induced significantly (p Conclusion Our study shows that endosperm and wholegrain rye products induce low acute insulinaemic responses and improved glycaemic profiles. The results also suggest that the rye products possess beneficial appetite regulating properties. Further studies are needed to identify the unknown property or bioactive component(s responsible for these beneficial metabolic features of rye.

    Full Text Available The article reflects the progress of genetic decrease of Rye F 3k- 10029/ Saratovske (Саратовське 4 height by means of the shortest stem plants selection during the period from 1974 to 2010. 37 years selection of the shortest- stern genotypes decreased the plants height from 119.33 cm to 22.57cm. Targeted selection into minus direction decreased the plants height in 5,29 times on the background of the dominant HI expression. In average, the height of plants in the course of 27 breeding cycles were decreasing by 2.69 cm, but that was not going gradually. A new donor Gnom 3 had been created for ultra short-stem trait of the Winter Rye, with the marking of alleles HI-3HI-3. Relative influence on the minus selection efficiency has been established by height of plants for the selection differential (38% and coefficient of inheritance in narrow sense (14,56%. Realized efficiency of selection in decrease of winter rye height in 72,08% of cases corresponded to predicted hit ration of the breeding. Analyzes of genetic and statistical parameters and correlation clusters of 11 utilitarian average characteristics of ultra short- stem rye Gnom 3 for the period of 1974 to 2010 has been performed.

    Allergenic cross reactivity between the members of the Pooids (Lolium perenne, Phleum pratense, and Poa pratensis) and Chloridoids (Cynodon dactylon and Paspalum notatum) is well established. Studies using crude extracts in the past have demonstrated limited cross reactivity between the Pooids and the Chloridoids suggesting separate diagnosis and therapy. However, little is known regarding the molecular basis for the limited cross reactivity observed between the 2 groups of grasses. The present study was undertaken to gain insights into the molecular basis of cross allergenicity between the major allergens from rye and Bermuda grass pollens. Immunoblot inhibition tests were carried out to determine the specificity of the proteins involved in cross reactivity. Crude pollen extract and bacterially expressed and purified recombinant Lol p 1and Lol p 5 from rye grass were subjected to cross inhibition experiments with crude and purified recombinant Cyn d 1 from Bermuda grass using sera from patients allergic to rye grass pollen. The immunoblot inhibition studies revealed a high degree of cross inhibition between the group 1 allergens. In contrast, a complete lack of inhibition was observed between Bermuda grass group 1 allergen rCyn d 1, and rye grass group 5 allergen rLol p 5. Crude rye grass extract strongly inhibited IgE reactivity to Bermuda grass, whereas crude Bermuda grass pollen extract showed a weaker inhibition. Our data suggests that a possible explanation for the limited cross reactivity between the Pooids and Chloridoids may, in part, be due to the absence of group 5 allergen from Chloridoid grasses. This approach of using purified proteins may be applied to better characterize the cross allergenicity patterns between different grass pollen allergens.

    Full Text Available BACKGROUND: Wheat-rye addition lines are an old topic. However, the alterations and abnormal mitotic behaviours of wheat chromosomes caused by wheat-rye monosomic addition lines are seldom reported. METHODOLOGY/PRINCIPAL FINDINGS: Octoploid triticale was derived from common wheat T. aestivum L. 'Mianyang11'×rye S. cereale L. 'Kustro' and some progeny were obtained by the controlled backcrossing of triticale with 'Mianyang11' followed by self-fertilization. Genomic in situ hybridization (GISH using rye genomic DNA and fluorescence in situ hybridization (FISH using repetitive sequences pAs1 and pSc119.2 as probes were used to analyze the mitotic chromosomes of these progeny. Strong pSc119.2 FISH signals could be observed at the telomeric regions of 3DS arms in 'Mianyang11'. However, the pSc119.2 FISH signals were disappeared from the selfed progeny of 4R monosomic addition line and the changed 3D chromosomes could be transmitted to next generation stably. In one of the selfed progeny of 7R monosomic addition line, one 2D chromosome was broken and three 4A chromosomes were observed. In the selfed progeny of 6R monosomic addition line, structural variation and abnormal mitotic behaviour of 3D chromosome were detected. Additionally, 1A and 4B chromosomes were eliminated from some of the progeny of 6R monosomic addition line. CONCLUSIONS/SIGNIFICANCE: These results indicated that single rye chromosome added to wheat might cause alterations and abnormal mitotic behaviours of wheat chromosomes and it is possible that the stress caused by single alien chromosome might be one of the factors that induced karyotype alteration of wheat.

    Full Text Available The identification and quantification of cereal storage proteins is of interest of many researchers. Their structural or functional properties are usually affected by the way how they are extracted. The efficiency of extraction process depends on the cereal source and working conditions. Here, we described various commonly used extraction protocols differing in the extraction conditions (pre-extraction of albumins/globulins, sequential extraction of individual protein fractions or co-extraction of gluten proteins, heating or non-heating, reducing or non-reducing conditions. The total protein content of all fractions extracted from commercially available wheat and rye flours was measured by the Bradford method. Tris-Tricine SDS-PAGE was used to determine the molecular weights of wheat gliadins, rye secalins and high-molecular weight glutelins which are the main triggering factors causing celiac disease. Moreover, we were able to distinguish individual subunits (α/β-, γ-, ω-gliadins and 40k-γ-, 75k-γ-, ω-secalins of wheat/rye prolamins. Generally, modified extraction protocols against classical Osborne procedure were more effective and yields higher protein content in all protein fractions. Bradford measurement led into underestimation of results in three extraction procedures, while all protein fractions were clearly identified on SDS-PAGE gels. Co-extraction of gluten proteins resulted in appearance of both, low-molecular weight fractions (wheat gliadins and rye secalins as well as high-molecular weight glutelins which means that is not necessary to extract gluten proteins separately. The two of three extraction protocols showed high technical reproducibility with coefficient of variation less than 20%. Carefully optimized extraction protocol can be advantageous for further analyses of cereal prolamins.  Normal 0 21 false false false SK X-NONE X-NONE

    Monosomic alien addition lines (MAALs) can easily induce structural variation of chromosomes and have been used in crop breeding; however, it is unclear whether MAALs will induce drastic genetic and epigenetic alterations. In the present study, wheat-rye 2R and 5R MAALs together with their selfed progeny and parental common wheat were investigated through amplified fragment length polymorphism (AFLP) and methylation-sensitive amplification polymorphism (MSAP) analyses. The MAALs in different generations displayed different genetic variations. Some progeny that only contained 42 wheat chromosomes showed great genetic/epigenetic alterations. Cryptic rye chromatin has introgressed into the wheat genome. However, one of the progeny that contained cryptic rye chromatin did not display outstanding genetic/epigenetic variation. 78 and 49 sequences were cloned from changed AFLP and MSAP bands, respectively. Blastn search indicated that almost half of them showed no significant similarity to known sequences. Retrotransposons were mainly involved in genetic and epigenetic variations. Genetic variations basically affected Gypsy-like retrotransposons, whereas epigenetic alterations affected Copia-like and Gypsy-like retrotransposons equally. Genetic and epigenetic variations seldom affected low-copy coding DNA sequences. The results in the present study provided direct evidence to illustrate that monosomic wheat-rye addition lines could induce different and drastic genetic/epigenetic variations and these variations might not be caused by introgression of rye chromatins into wheat. Therefore, MAALs may be directly used as an effective means to broaden the genetic diversity of common wheat.

    Full Text Available Rye (Secale cereale L. possesses many valuable genes that can be used for improving disease resistance, yield and environment adaptation of wheat (Triticum aestivum L.. However, the documented resistance stocks derived from rye is faced severe challenge due to the variation of virulent isolates in the pathogen populations. Therefore, it is necessary to develop desirable germplasm and search for novel resistance gene sources against constantly accumulated variation of the virulent isolates. In the present study, a new wheat-rye line designated as WR49-1 was produced through distant hybridization and chromosome engineering protocols between common wheat cultivar Xiaoyan 6 and rye cultivar German White. Using sequential GISH (genomic in situ hybridization, mc-FISH (multicolor fluorescence in situ hybridization, mc-GISH (multicolor GISH and EST (expressed sequence tag-based marker analysis, WR49-1 was proved to be a new wheat-rye 6R disomic addition line. As expected, WR49-1 showed high levels of resistance to wheat powdery mildew (Blumeria graminis f. sp. tritici, Bgt pathogens prevalent in China at the adult growth stage and 19 of 23 Bgt isolates tested at the seedling stage. According to its reaction pattern to different Bgt isolates, WR49-1 may possess new resistance gene(s for powdery mildew, which differed from the documented powdery mildew gene, including Pm20 on chromosome arm 6RL of rye. Additionally, WR49-1 was cytologically stable, had improved agronomic characteristics and therefore could serve as an important bridge for wheat breeding and chromosome engineering.

    The narrow genetic variation present in common wheat (Triticum aestivum) varieties has greatly restricted the improvement of crop yield in modern breeding systems. Alien addition lines have proven to be an effective means to broaden the genetic diversity of common wheat. Wheat-rye addition lines, which are the direct bridge materials for wheat improvement, have been wildly used to produce new wheat cultivars carrying alien rye germplasm. In this study, we investigated the genetic and epigenetic alterations in two sets of wheat-rye disomic addition lines (1R-7R) and the corresponding triticales. We used expressed sequence tag-simple sequence repeat, amplified fragment length polymorphism, and methylation-sensitive amplification polymorphism analyses to analyze the effects of the introduction of alien chromosomes (either the entire genome or sub-genome) to wheat genetic background. We found obvious and diversiform variations in the genomic primary structure, as well as alterations in the extent and pattern of the genomic DNA methylation of the recipient. Meanwhile, these results also showed that introduction of different rye chromosomes could induce different genetic and epigenetic alterations in its recipient, and the genetic background of the parents is an important factor for genomic and epigenetic variation induced by alien chromosome addition.

    Full Text Available BACKGROUND: Monosomic alien addition lines (MAALs can easily induce structural variation of chromosomes and have been used in crop breeding; however, it is unclear whether MAALs will induce drastic genetic and epigenetic alterations. METHODOLOGY/PRINCIPAL FINDINGS: In the present study, wheat-rye 2R and 5R MAALs together with their selfed progeny and parental common wheat were investigated through amplified fragment length polymorphism (AFLP and methylation-sensitive amplification polymorphism (MSAP analyses. The MAALs in different generations displayed different genetic variations. Some progeny that only contained 42 wheat chromosomes showed great genetic/epigenetic alterations. Cryptic rye chromatin has introgressed into the wheat genome. However, one of the progeny that contained cryptic rye chromatin did not display outstanding genetic/epigenetic variation. 78 and 49 sequences were cloned from changed AFLP and MSAP bands, respectively. Blastn search indicated that almost half of them showed no significant similarity to known sequences. Retrotransposons were mainly involved in genetic and epigenetic variations. Genetic variations basically affected Gypsy-like retrotransposons, whereas epigenetic alterations affected Copia-like and Gypsy-like retrotransposons equally. Genetic and epigenetic variations seldom affected low-copy coding DNA sequences. CONCLUSIONS/SIGNIFICANCE: The results in the present study provided direct evidence to illustrate that monosomic wheat-rye addition lines could induce different and drastic genetic/epigenetic variations and these variations might not be caused by introgression of rye chromatins into wheat. Therefore, MAALs may be directly used as an effective means to broaden the genetic diversity of common wheat.

    Ethanol production from lignocellulosic materials provides an alternative energy production system. Rye and bermudagrass that are used in hog farms for nutrient uptake from swine wastewater have the potential for fuel ethanol production because they have a relative high cellulose and hemicellulose content. Dilute sulfuric acid pretreatment of rye straw and bermudagrass before enzymatic hydrolysis of cellulose was investigated in this study. The biomass at a solid loading rate of 10% was pretreated at 121 deg C with different sulfuric acid concentrations (0.6, 0.9, 1.2 and 1.5%, w/w) and residence times (30, 60, and 90 min). Total reducing sugars, arabinose, galactose, glucose, and xylose in the prehydrolyzate were analyzed. In addition, the solid residues were hydrolyzed by cellulases to investigate the enzymatic digestibility. With the increasing acid concentration and residence time, the amount of arabinose and galactose in the filtrates increased. The glucose concentration in the prehydrolyzate of rye straw was not significantly influenced by the sulfuric acid concentration and residence time, but it increased in the prehydrolyzate of bermudagrass with the increase of pretreatment severity. The xylose concentration in the filtrates increased with the increase of sulfuric acid concentration and residence time. Most of the arabinan, galactan and xylan in the biomass were hydrolyzed during the acid pretreatment. Cellulose remaining in the pretreated feedstock was highly digestible by cellulases from Trichoderma reesei. (Author)

    To determine whether consumption of whole-grain rye bread, oatmeal, and whole-wheat bread, during different periods of life, is associated with risk of prostate cancer (PCa). From 2002 to 2006, 2,268 men, aged 67-96 years, reported their dietary habits in the AGES-Reykjavik cohort study. Dietary habits were assessed for early life, midlife, and current life using a validated food frequency questionnaire. Through linkage to cancer and mortality registers, we retrieved information on PCa diagnosis and mortality through 2009. We used regression models to estimate odds ratios (ORs) and hazard ratios (HRs) for PCa according to whole-grain consumption, adjusted for possible confounding factors including fish, fish liver oil, meat, and milk intake. Of the 2,268 men, 347 had or were diagnosed with PCa during follow-up, 63 with advanced disease (stage 3+ or died of PCa). Daily rye bread consumption in adolescence (vs. less than daily) was associated with a decreased risk of PCa diagnosis (OR = 0.76, 95 % confidence interval (CI): 0.59-0.98) and of advanced PCa (OR = 0.47, 95 % CI: 0.27-0.84). High intake of oatmeal in adolescence (≥5 vs. ≤4 times/week) was not significantly associated with risk of PCa diagnosis (OR = 0.99, 95 % CI: 0.77-1.27) nor advanced PCa (OR = 0.67, 95 % CI: 0.37-1.20). Midlife and late life consumption of rye bread, oatmeal, or whole-wheat bread was not associated with PCa risk. Our results suggest that rye bread consumption in adolescence may be associated with reduced risk of PCa, particularly advanced disease.

    Cover crop benefits include nitrogen accumulation and retention, weed suppression, organic matter maintenance, and reduced erosion. Organic farmers need region-specific information on winter cover crop performance to effectively integrate cover crops into their crop rotations. Our research objective was to compare cover crop seeding mixtures, planting dates, and termination dates on performance of rye (Secale cereale L.) and hairy vetch (Vicia villosa Roth) monocultures and mixtures in the maritime Pacific Northwest USA. The study included four seed mixtures (100% hairy vetch, 25% rye-75% hairy vetch, 50% rye-50% hairy vetch, and 100% rye by seed weight), two planting dates, and two termination dates, using a split-split plot design with four replications over six years. Measurements included winter ground cover; stand composition; cover crop biomass, N concentration, and N uptake; and June soil NO3(-)-N. Rye planted in mid-September and terminated in late April averaged 5.1 Mg ha(-1) biomass, whereas mixtures averaged 4.1 Mg ha(-1) and hairy vetch 2.3 Mg ha(-1). Delaying planting by 2.5 weeks reduced average winter ground cover by 65%, biomass by 50%, and cover crop N accumulation by 40%. Similar reductions in biomass and N accumulation occurred for late March termination, compared with late April termination. Mixtures had less annual biomass variability than rye. Mixtures accumulated 103 kg ha(-1) N and had mean C:N ratio rye, 97 kg ha(-1) for the mixtures, and 119 kg ha(-1) for hairy vetch. Weeds comprised less of the mixtures biomass (20% weeds by weight at termination) compared with the monocultures (29%). Cover crop mixtures provided a balance between biomass accumulation and N concentration, more consistent biomass over the six-year study, and were more effective at reducing winter weeds compared with monocultures.

    Rye products have been reported to elicit postprandial insulin and glucose responses which may be beneficial for prevention of type-2 diabetes. However, mechanisms underlying variations in responses related to processing techniques are not fully understood. Five differently processed rye products (sourdough-fermented bread, fermented and unfermented crispbread, extrusion-cooked rye, and porridge) and refined wheat bread were characterised. Two in vitro methods, a dynamic method simulating digestion in the stomach and small intestine and a static method, simulating conditions in the stomach were used to determine viscosity development, structural changes and release of glucose during digestion. Structural and compositional differences induced by processing influenced product digestion. Gastric disintegration and digesta particle size were related to characteristics of the starch/protein matrix, while digesta viscosity was reduced due to fibre degradation during fermentation. More cohesive boluses were associated with slower glucose release. Sourdough fermentation increased amylose leakage and appeared to inhibit starch hydrolysis despite low digesta viscosity and rapid disintegration. The net release of glucose during digestion of foods is determined by several factors which may vary in their importance depending on product specific properties.

    Full Text Available This study was carried out on Rhynchosprium secalis (Oud. J. J. Davis occurring on spring barley, winter rye and couch grass (Agropyron repens (L. PB in Finland. The results were obtained from samples of barley (c. 860 samples and rye (c. 200 samples gathered in fields during the growing season throughout the country in 1971 1973. The samples (c. 170 samples of Agropyron repens were collected in fields and the borders of fields. The fungi of all the samples were examined by microscope and cultures and inocolation tests were used as well. Rhynchosporium secalis was observed to occur commonly on spring barley throughout the country from Helsinki to Lapland. The fungus was observed in about 30 per cent of the fields and in below 60 percent of the localities examined. Leaf blotch was commoner on six rowed barley than on two-rowed barley. The fungus sometimes attacked a field in great profusion. R. secalis was observed in below 50 per cent of the winter rye samples and in below 70 per cent of the localities examined. The fungus occurred commonly in the southern part of Finland and was found also in Lapland (Inari, 69° N, 27°E. Spores of the fungus were most abundant in the leaves of rye in spring and in early summer. R. secalis was observed rather scarce (in over 10 per cent of fields and in over 25 per cent of the localities examined on Agropyron repens throughout the country. A high degree of host specialisation has been found within the species R. secalis. Two isolates from spring barley and from winter rye were pathogenic to their original host only.

    Full Text Available Kvass based on traditional technology completely disappeared from polish market. It was replaced by drinks, prepared from malt concentrates, wrongly named kvass. The aim of this study was therefore to obtain traditional bread kvass (by fermentation, using the mash prepared from commercial wholemeal rye bread, produced by 5-phase dough fermentation method, and to determine the quality of this kvass in terms of consumer acceptance, chemical composition and antioxidant activity. It has been demonstrated that based on the traditional wholemeal rye bread, it is possible to produce good quality bread kvass, with similar organoleptic qualities to the commercial kvasses, which contain several added flavours and preservatives. Natural bread kvass can be consumed by consumers of all ages, since it contains only trace amounts of alcohol, and it has almost double the dietary fibre content and three times lower content of reducing sugars as compared to the commercial kvasses. Laboratory made kvasses by natural fermentation also showed an increase in antioxidant activity by 60%, when compared to commercial kvasses.

    Full Text Available Abstract Background Epidemiological studies have consistently shown that whole grain (WG cereals can protect against the development of chronic diseases, but the underlying mechanism is not fully understood. Among WG products, WG rye is considered even more potent because of its unique discrepancy in postprandial insulin and glucose responses known as the rye factor. In this study, an NMR-based metabolomics approach was applied to study the metabolic effects of WG rye as a tool to determine the beneficial effects of WG rye on human health. Methods Thirty-three postmenopausal Finnish women with elevated serum total cholesterol (5.0-8.5 mmol/L and BMI of 20–33 kg/m2 consumed a minimum of 20% of their daily energy intake as high fiber WG rye bread (RB or refined wheat bread (WB in a randomized, controlled, crossover design with two 8-wk intervention periods separated by an 8-wk washout period. At the end of each intervention period, fasting serum was collected for NMR-based metabolomics and the analysis of cholesterol fractions. Multilevel partial least squares discriminant analysis was used for paired comparisons of multivariate data. Results The metabolomics analysis of serum showed lower leucine and isoleucine and higher betaine and N,N-dimethylglycine levels after RB than WB intake. To further investigate the metabolic effects of RB, the serum cholesterol fractions were measured. Total- and LDL-cholesterol levels were higher after RB intake than after WB (p Conclusions This study revealed favorable shifts in branched amino acid and single carbon metabolism and an unfavorable shift in serum cholesterol levels after RB intake in postmenopausal women, which should be considered for evaluating health beneficial effects of rye products.

    The U.S. Department of Energy (DOE) estimates that there were about 700 million downlight luminaires installed in residential and commercial buildings in the U.S. as of 2012, with light-emitting diode (LED) luminaires representing less than 1% of this installed base. Downlight luminaires using conventional incandescent, halogen, and compact fluorescent lamps have lower efficacies and shorter expected lifetimes than comparable LED systems, but the lower initial cost of the conventional technology and the uncertainties associated with the newer LED technology have restricted widespread adoption of LED downlight luminaires. About 278 tBtu of energy could be saved annually if LED luminaires were to saturate the downlight market, equating to an annual energy cost savings of $2.6 billion. This report summarizes an evaluation of LED recessed downlight luminaires in the guest rooms at the Hilton Columbus Downtown hotel in Columbus, OH. The facility opened in October of 2012, and the U.S. Department of Energy (DOE) conducted a post-occupancy assessment of the facility in January–March of 2014. Each of the 484 guest rooms uses seven 15 W LED downlights: four downlights in the entry and bedroom and three downlights in the bathroom. The 48 suites use the seven 15 W LED downlights and additional fixtures depending on the space requirements, so that in total the facility has more than 3,700 LED downlights. The downlights are controlled through wall-mounted switches and dimmers. A ceiling-mounted vacancy sensor ensures that the bathroom luminaires are turned off when the room is not occupied.

    Changes in chemical composition and antioxidative properties of rye ginger cakes during their shelf-life were investigated in this study. In particular, the changes in antioxidants content, antioxidative and reducing capacity, and Maillard reaction development in rye ginger cakes after long-term storage were addressed. Ginger cakes produced according to the traditional and current recipe were stored for 5 years at room temperature in a dark place. The total phenolic compounds (TPC), inositol hexaphosphate (IP6), reduced (GSH) and oxidised glutathione (GSSG) contents, antioxidant and reducing capacity and Maillard reaction products (MRPs) were determined in ginger cakes after storage and then compared to those measured after baking. After long-term storage a decrease in TPC and IP6 contents in cakes was noted. In contrast, an increase in antioxidative and reducing capacity of stored cakes was observed. Long-term storage induced formation of furosine, advanced and final Maillard reaction products and caused changes in both reduced and oxidised forms of glutathione. After long-term storage the modest changes in furosine, FAST index and browning in ginger cake formulated with dark rye flour may suggest that this product is the healthiest among others. Therefore, traditional rye ginger cakes can be considered as an example of a healthy food that is also relatively stable during long term storage as noted by the small chemical changes observed in its composition.

    Fermentation of rye dough is often accompanied with an increase in folate content. In this study, three sourdough yeasts, Candida milleri CBS 8195, Saccharomyces cerevisiae TS 146, and Torulaspora delbrueckii TS 207; a control, baker's yeast S. cerevisiae ALKO 743; and four Lactobacillus spp., L. acidophilus TSB 262, L. brevis TSB 307, L. plantarum TSB 304, and L. sanfranciscensis TSB 299 originally isolated from rye sourdough were examined for their abilities to produce or consume folates. The microorganisms were grown in yeast extract-peptone-d-glucose medium as well as in small-scale fermentations that modelled the sourdough fermentation step used in rye baking. Total folate contents were determined using Lactobacillus rhamnosus (ATCC 7469) as the growth indicator organism. The microorganisms studied did not excrete folates into the media in significant amounts. Yeasts increased the folate contents of sterilised rye flour-water mixtures from 6.5 microg/100 g to between 15 and 23 microg/100 g after 19-h fermentation, whereas lactic acid bacteria decreased it to between 2.9 and 4.2 microg/100 g. Strains of Lactobacillus bulgaricus, L. casei, L. curvatus, L. fermentum, L. helveticus, Pediococcus spp., and Streptococcus thermophilus that were also tested gave folate contents after fermentation that varied between 2 and 10.4 microg/100 g. Although the four Lactobacillus spp. from sourdough consumed folates their effect on folate contents in co-cultivations was minimal. It was concluded that the increase of folate content during fermentation was mainly due to folate synthesis by yeasts. Fermentation of non-sterilised flour-water mixtures as such resulted in three-fold increases in the folate contents. Two folate producing bacteria were isolated from the non-sterilised flour and identified as Enterobacter cowanii and Pantoea agglomerans.

    Zagroba, Marek; Gawryluk, Dorota

    2017-12-01

    Old towns in spatial structures of historic towns are the areas which - same as centuries before - serve as the town centres. This is almost invariably true about small towns especially, as the inner town district is more frequently the site where a town was originally located and is often the manifestation of its historic identity. However, functional and spatial problems of many small historic towns arise from the above trend, mostly because of the frequently high density of buildings in the oldest part of a town. The intricate nature of elements creating the structure of a town’s historic centre often calls for certain steps to be taken, which will ensure better exposure of an old town complex against the backdrop of the town’s other areas. Numerous problems need to be solved, not only spatial but also economic and social ones. A town is a living organism, inhabited by people. The key to tackling these issues successfully lies in the creation of such revitalisation programmes that will improve the quality of space and help achieve the sustainable development of inner-town areas in historic towns. The historic centres in the medieval towns of Warmia, a region rich in history and situated in north-eastern Poland, can serve as an example and has been investigated in the following study. All the towns in Warmia located in the Middle Ages, except the capital of the region Olsztyn, can be classified as small urban developments. This group of eleven towns is dominated by the ones whose territorial coverage has not changed considerably since the location and the population ranges from a few thousand to less than twenty thousand. To this day, the historic quarters of these towns have remained the central ones in each town, and their urban structures to a various extent reveal the features characteristic for the period when they were created. The differences are due to the war damage the towns suffered at the end of World War Two and because of the different ways in

    In order to investigation of allelopathic effects of some ornamental trees on seed germination of rye-grass (Lolium prenne) and tall fescue (Festuca arundinaceae), this experiment was conducted in a randomized complete block design with 3 replicates at the laboratory of Horticultural Sciences Department of Ferdowsi University of Mashhad, during 2008. In this research, we studied the effect of aqueous and hydro-alcoholic extracts of Afghanistan pine (Pinus eldarica), arizona cypress (Cupressus arizonica), black locust (Robinia psedue acacia) and box elder (Acer negundo) leaves that prepared in 1:5 ratio on seed germination percent and rate for two grasses. The results showed that all extracts decreased statistically seed germination in compared to control treatment. The highest germination percentage and germination rate of tested grass detected in control treatment. Hydro-alcoholic extracts of all woody plants (15, 30%) were completely inhibited seed germination of rye-grass and tall fescue. Also aqueous extract of arizona cypress was completely inhibited seed germination of tall fescue and had more inhibitory activity than other aqueous extracts on rye-grass. Between aqueous extracts, the highest and lowest seed germination of rye-grass was found in Afghanistan pine and arizona cypress, respectively.

    For rye dough structure, it is hypothesised that the presence of arabinoxylan hinders the proteins from forming a coherent network. This hypothesis was investigated using fluorescent-stained antibodies that bind to the arabinoxylan chains. Image analysis proves that the arabinoxylan surrounds the proteins, negatively affecting protein networking. Further, it is hypothesised that the dosing of xylanase and transglutaminase has a positive impact on rye dough and bread characteristics; the findings in this study evidenced that this increases the protein network by up to 38% accompanied by a higher volume rise of 10.67%, compared to standard rye dough. These outcomes combine a product-oriented and physiochemical design of a recipe, targeting structural and functional relationships, and demonstrate a successful methodology for enhancing rye bread quality.

    The concentration of benzoxazinoids (BX) was measured in field soils at selected intervals after rye residue was either incorporated or left on the soil surface. The spectrum of compounds arising in the soil persisted approximately two weeks and was dominated by methoxy containing BX compounds, which were only minor components of the rye foliage. Growth assays with lettuce and smooth pigweed species showed inhibition when treated soils were tested during the first two weeks after rye applications; however, there were no sufficient concentrations of any one BX compound in the soil to explain these affects. Solution applications of two pure BX compounds, benzoxazolin-2(3H)-one (BOA) and 6-methoxy-benzoxazolin-2(3H)-one (MBOA), to the surface of soils revealed that movement into the soil column was minimal (greater than 70% BOA and 97% MBOA remained in the top 1-cm of soil profiles) and that the time course for their complete dissipation was less than 24 h.

    A study by the U.S. Geological Survey from April 1982 through December 1983 evaluated the effects of high-rate disposal of treated wastewater on the water table aquifer, Hilton Head Island, South Carolina. Flooding of topographically low areas resulted from the application of 10.8 inches of wastewater in 10 days in January 1983. The water table remained 2-1/2 to 5-1/2 feet below land surface when wastewater was applied at rates of 5 inches per week in August and December 1983. (USGS)

    Whole-grain rye foods reduce appetite, insulin and sometimes glucose responses. Increased gut fermentation and plant protein may mediate the effect. The aims of the present study were to investigate whether the appetite-suppressing effects of whole-grain rye porridge could be enhanced by replacing part of the rye with fermented dietary fibre and plant protein, and to explore the role of gut fermentation on appetite and metabolic responses over 8 h. We conducted a randomised, cross-over study using two rye porridges (40 and 55 g), three 40-g rye porridges with addition of inulin:gluten (9:3; 6:6; 3:9 g) and a refined wheat bread control (55 g), served as part of complete breakfasts. A standardised lunch and an ad libitum dinner were served 4 and 8 h later, respectively. Appetite, breath hydrogen and methane, glucose, insulin and glucagon-like peptide-1 (GLP-1) responses were measured over 8 h. Twenty-one healthy men and women, aged 23-60 years, with BMI of 21-33 kg/m2 participated in this study. Before lunch, the 55-g rye porridges lowered hunger by 20 % and desire to eat by 22 % and increased fullness by 29 % compared with wheat bread (Pinulin and gluten compared with plain rye porridges.

  19. Winter rye as a bioenergy feedstock: impact of crop maturity on composition, biological solubilization and potential revenue.

    Winter annual crops such as winter rye (Secale cereale L) can produce biomass feedstock on seasonally fallow land that continues to provide high-value food and feed from summer annuals such as corn and soybeans. As energy double crops, winter grasses are likely to be harvested while still immature and thus structurally different from the fully senesced plant material typically used for biofuels. This study investigates the dynamic trends in biomass yield, composition, and biological solubilization over the course of a spring harvest season. The water soluble fraction decreased with increasing maturity while total carbohydrate content stayed roughly constant at about 65%. The protein mass fraction decreased with increasing maturity, but was counterbalanced by increasing harvest yield resulting in similar total protein across harvest dates. Winter rye was ground and autoclaved then fermented at 15 g/L total solids by either (1) Clostridium thermocellum or (2) simultaneous saccharification and cofermentation (SSCF) using commercial cellulases (CTec2 and HTec2) and a xylose-fermenting Saccharomyces cerevisiae strain. Solubilization of total carbohydrate dropped significantly as winter rye matured for both C. thermocellum (from approximately 80% to approximately 50%) and SSCF (from approximately 60% to approximately 30%). C. thermocellum achieved total solubilization 33% higher than that of SSCF for the earliest harvest date and 50% higher for the latest harvest date. Potential revenue from protein and bioethanol was stable over a range of different harvest dates, with most of the revenue due to ethanol. In a crop rotation with soybean, recovery of the soluble protein from winter rye could increase per hectare protein production by 20 to 35%. Double-cropping winter rye can produce significant biomass for biofuel production and feed protein as coproduct without competing with the main summer crop. During a 24-day harvest window, the total carbohydrate content remained

    The existence of hybrid dwarfs from intraspecific crosses in wheat (Triticum aestivum) was described 100 years ago, and the genetics underlying hybrid dwarfness are well understood. In this study, we report a dwarf phenotype in interspecific hybrids between wheat and rye (Secale cereale). We identified two rye lines that produce hybrid dwarfs with wheat and have none of the hitherto known hybrid dwarfing genes. Genetic analyses revealed that both rye lines carry a single allelic gene responsible for the dwarf phenotype. This gene was designated Hdw-R1 (Hybrid dwarf-R1). Application of gibberellic acid (GA3 ) to both intraspecific (wheat-wheat) and interspecific (wheat-rye) hybrids showed that hybrid dwarfness cannot be overcome by treatment with this phytohormone. Histological analysis of shoot apices showed that wheat-rye hybrids with the dwarf phenotype at 21 and 45 days after germination failed to develop further. Shoot apices of dwarf plants did not elongate, did not form new primordia and had a dome-shaped appearance in the seed. The possible relationship between hybrid dwarfness and the genes responsible for the transition from vegetative to generative growth stage is discussed. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Phenolic acids have been reported to play a role on the antioxidant activity and other important biological activities. However, as most polyphenolics in food products are either bound to cellular matrices or present as free polymeric forms, the way they are absorbed has not been totally clear until now. Hydrolytic enzymes may act to increase functionalities in polyphenolic-rich foods, enhancing the bioaccessibility of phenolic compounds and minerals from whole grains. The aim of this study was to evaluate the action of tannin acyl hydrolase (tannase) on the total phenols, phenolic acid profile, antioxidant capacity and in vitro bioaccessibility of phenolic acids found in whole rye flour (RF). Besides increasing total phenols and the antioxidant capacity, tannase treatment increased the amounts of ferulic, sinapic and vanillic acids identified in RF, evidencing a new type of feruloyl esterase catalytic action of tannase. Vanillic and sinapic acids in tannase-treated whole rye flour (RFT) were higher than RF after in vitro gastrointestinal digestion, and higher amounts of transported vanillic acid through the Caco-2 monolayer were detected in RFT. However, the bioaccessibility and the transport efficiency of RF phenolic acids were higher than RFT. Underutilized crops like rye and rye-derived products may be an important source of phenolic acids. The tannase biotransformation, even influencing the total phenolics and antioxidant capacity of RF, did not increase the bioaccessibility of phenolic acids under the experimental conditions of this study.

    2007-01-01

    A significant portion of the NO3 from agricultural fields that contaminates surface waters in the Midwest Corn Belt is transported to streams or rivers by subsurface drainage systems or "tiles." Previous research has shown that N fertilizer management alone is not sufficient for reducing NO3 concentrations in subsurface drainage to acceptable levels; therefore, additional approaches need to be devised. We compared two cropping system modifications for NO3 concentration and load in subsurface drainage water for a no-till corn (Zea mays L.)-soybean (Glycine max [L.] Merr.) management system. In one treatment, eastern gamagrass (Tripsacum dactyloides L.) was grown in permanent 3.05-m-wide strips above the tiles. For the second treatment, a rye (Secale cereale L.) winter cover crop was seeded over the entire plot area each year near harvest and chemically killed before planting the following spring. Twelve 30.5x42.7-m subsurface-drained field plots were established in 1999 with an automated system for measuring tile flow and collecting flow-weighted samples. Both treatments and a control were initiated in 2000 and replicated four times. Full establishment of both treatments did not occur until fall 2001 because of dry conditions. Treatment comparisons were conducted from 2002 through 2005. The rye cover crop treatment significantly reduced subsurface drainage water flow-weighted NO3 concentrations and NO3 loads in all 4 yr. The rye cover crop treatment did not significantly reduce cumulative annual drainage. Averaged over 4 yr, the rye cover crop reduced flow-weighted NO3 concentrations by 59% and loads by 61%. The gamagrass strips did not significantly reduce cumulative drainage, the average annual flow-weighted NO3 concentrations, or cumulative NO3 loads averaged over the 4 yr. Rye winter cover crops grown after corn and soybean have the potential to reduce the NO3 concentrations and loads delivered to surface waters by subsurface drainage systems.

    Powdery mildew is one of the serious diseases of wheat (Triticum aestivum L., 2 n = 6 × = 42, genomes AABBDD). Rye (Secale cereale L., 2 n = 2 × = 14, genome RR) offers a rich reservoir of powdery mildew resistant genes for wheat breeding program. However, extensive use of these resistant genes may render them susceptible to new pathogen races because of co-evolution of host and pathogen. Therefore, the continuous exploration of new powdery mildew resistant genes is important to wheat breeding program. In the present study, we identified several wheat-rye addition lines from the progeny of T. aestivum L. Mianyang11 × S. cereale L. Kustro, i.e., monosomic addition lines of the rye chromosomes 4R and 6R; a disomic addition line of 6R; and monotelosomic or ditelosomic addition lines of the long arms of rye chromosomes 4R (4 RL) and 6R (6 RL). All these lines displayed immunity to powdery mildew. Thus, we concluded that both the 4 RL and 6 RL arms of Kustro contain powdery mildew resistant genes. It is the first time to discover that 4 RL arm carries powdery mildew resistant gene. Additionally, wheat lines containing new wheat-rye translocation chromosomes were also obtained: these lines retained a short arm of wheat chromosome 5D (5 DS) on which rye chromosome 4R was fused through the short arm 4 RS (designated 5 DS-4 RS · 4 RL; 4 RL stands for the long arm of rye chromosome 4R); or they had an extra short arm of rye chromosome 4R (4 RS) that was attached to the short arm of wheat chromosome 5D (5 DS) (designated 4 RS-5 DS · 5 DL; 5 DL stands for the long arm of wheat chromosome 5D). These two translocation chromosomes could be transmitted to next generation stably, and the wheat lines containing 5 DS-4 RS · 4 RL chromosome also displayed immunity to powdery mildew. The materials obtained in this study can be used for wheat powdery mildew resistant breeding program.

  12. Interplay of ribosomal DNA loci in nucleolar dominance: dominant NORs are up-regulated by chromatin dynamics in the wheat-rye system.

    Directory of Open Access Journals (Sweden)

    Manuela Silva

    Full Text Available BACKGROUND: Chromatin organizational and topological plasticity, and its functions in gene expression regulation, have been strongly revealed by the analysis of nucleolar dominance in hybrids and polyploids where one parental set of ribosomal RNA (rDNA genes that are clustered in nucleolar organizing regions (NORs, is rendered silent by epigenetic pathways and heterochromatization. However, information on the behaviour of dominant NORs is very sparse and needed for an integrative knowledge of differential gene transcription levels and chromatin specific domain interactions. METHODOLOGY/PRINCIPAL FINDINGS: Using molecular and cytological approaches in a wheat-rye addition line (wheat genome plus the rye nucleolar chromosome pair 1R, we investigated transcriptional activity and chromatin topology of the wheat dominant NORs in a nucleolar dominance situation. Herein we report dominant NORs up-regulation in the addition line through quantitative real-time PCR and silver-staining technique. Accompanying this modification in wheat rDNA trascription level, we also disclose that perinucleolar knobs of ribosomal chromatin are almost transcriptionally silent due to the residual detection of BrUTP incorporation in these domains, contrary to the marked labelling of intranucleolar condensed rDNA. Further, by comparative confocal analysis of nuclei probed to wheat and rye NORs, we found that in the wheat-rye addition line there is a significant decrease in the number of wheat-origin perinucleolar rDNA knobs, corresponding to a diminution of the rDNA heterochromatic fraction of the dominant (wheat NORs. CONCLUSIONS/SIGNIFICANCE: We demonstrate that inter-specific interactions leading to wheat-origin NOR dominance results not only on the silencing of rye origin NOR loci, but dominant NORs are also modified in their transcriptional activity and interphase organization. The results show a cross-talk between wheat and rye NORs, mediated by ribosomal chromatin

  13. Impact of cell wall-degrading enzymes on water-holding capacity and solubility of dietary fibre in rye and wheat bran.

    Rye and wheat bran were treated with several xylanases and endoglucanases, and the effects on physicochemical properties such as solubility, viscosity, water-holding capacity and particle size as well as the chemical composition of the soluble and insoluble fractions of the bran were studied. A large number of enzymes with well-defined activities were used. This enabled a comparison between enzymes of different origins and with different activities as well as a comparison between the effects of the enzymes on rye and wheat bran. The xylanases derived from Bacillus subtilis were the most effective in solubilising dietary fibre from wheat and rye bran. There was a tendency for a higher degree of degradation of the soluble or solubilised dietary fibre in rye bran than in wheat bran when treated with most of the enzymes. None of the enzymes increased the water-holding capacity of the bran or the viscosity of the aqueous phase. The content of insoluble material decreased as the dietary fibre was solubilised by the enzymes. The amount of material that may form a network to retain water in the system was thereby decreased. © 2012 Society of Chemical Industry.

  14. Effect of Drought Stress on Water Use Efficiency and Root Dry Weight of Wheat (Triticum aesativum L. and Rye (Secale cereale L. in Competition Conditions

    Full Text Available Introduction Deficiency of water during the plant growth is one of the main factors which reduce the crops production around the world. Drought stress is one of the most important tensions that may occur around the low rainfall, high temperature and wind blowing environments. Plant response to this stress depends on the stage of plant growth and drought intensity. Weeds are unwanted and harmful plants with disturbance in agricultural practices which make increase the cost of crop production and reduce the crop yields. Rye (Secale cereal L. is one of the most important weeds at wheat fields in Iran (Baghestani and Atri, 2003. Low expectations, allelopathic effects and similarity of life cycle and morphology, caused increasing of rye density in winter wheat fields. Water use efficiency (WUE as an important physiological characteristic indicates the ability of plants to water stress. WUE may be affected by climatic and soil or plant factors. In plant communities, competition is one of most important physiological topics (Evans et al, 2003. At Inter-specific competition, weeds interfere to absorbing of light, water and nutrients through the adjacency with crop and so affect the growth and yield of crops. Weeds often compete with crops for soil water and reduce the accessibility of water. Competition between weeds and crops decrease the soil moisture and cause water stress which might decrease the weeds and crops growth. When the supply of water is limited, water drainage overlap areas in soil profile could be occurred relatively fast at early of in the crop life cycle. Materials and Methods In order to study the effects of drought stress on water use efficiency and root dry weight of wheat (Triticum aesativum L. and rye (Secale cereale L. in competition conditions, a pot experiment was conducted in the greenhouse of Agriculture Faculty , University of Birjand in 2012. The experiment was arranged as factorial based on completely randomized design

    Full Text Available Germinability and the content of soluble carbohydrates were analysed in cereal seed (winter rye, cv. Warko; spring wheat, cv. Santa; hexaploid winter triticale, cv. Fidelio and cv. Woltario. Seed moisture content (mc was equilibrated over silica gel to 0.08 g H2O/g dry mass and stored in a desiccator at 20oC for up to 205 weeks or were equilibrated to mc 0.06, 0.08 or 0.10 g H2O/g dm and subjected to artificial aging at 35oC in air-tight laminated aluminium foil packages for 205 weeks. It was shown that the rate of seed aging depended on the species and seed moisture content. The fastest decrease of germinability upon storage was observed in seed with the highest moisture level. Complete germinability loss for winter rye, winter triticale cv. Fidelio, winter triticale cv. Woltario and spring wheat seed with mc 0.10 g H2O/g dm3 occurred after 81, 81, 101 and 133 weeks, respectively. Fructose, glucose, galactose, myo-inositol, sucrose, galactinol, raffinose, stachyose and verbascose were the main soluble carbohydrates found in the seed. The obtained data on the contents of specific sugars and the composition of soluble sugars fraction in seed of rye, wheat and triticale did not corroborate any profound effect of reducing sugars, sucrose and oligosaccharides on seed longevity.

    The consumption of fiber-rich foods such as cereal bran is highly recommended due to its beneficial health effects. Pre-fermentation of bran with lactic acid bacteria can be used to improve the otherwise impaired flavor and textural qualities of bran-rich products. These positive effects are attributed to enzymatic modification of bran components and the production of functional metabolites like organic acids and exopolysaccharides such as dextrans. The aim of this study was to investigate dextran production in wheat and rye bran by fermentation with two Weissella confusa strains. Bran raw materials were analyzed for their chemical compositions and mineral content. Microbial growth and acidification kinetics were determined from the fermentations. Both strains produced more dextran in rye bran in which the fermentation-induced acidification was slower and the acidification lag phase longer than in wheat bran. Higher dextran production in rye bran is expected to be due to the longer period of optimal pH for dextran synthesis during fermentation. The starch content of wheat bran was higher, which may promote isomaltooligosaccharide formation at the expense of dextran production. W. confusa Cab3 produced slightly higher amounts of dextran than W. confusa VTT E-90392 in all raw materials. Fermentation with W. confusa Cab3 also resulted in lower residual fructose content which has technological relevance. The results indicate that wheat and particularly rye bran are promising matrices for producing technologically significant amounts of dextran, which facilitates the use of nutritionally valuable raw bran in food applications.

    lignan precursors, i.e., secoisolariciresinol and matairesinol. No statistically significant difference was observed in the incidence and multiplicity of small intestinal and colon tumors at terminal sacrifice between mice fed the control diet or the diet supplemented with 5% flaxseed. With the rye bran...... diet a statistically significant enhancement of the number of small intestinal tumors in female mice was observed. The number of colon tumors, however, was comparable between the control and rye bran-fed mice of either sex. Furthermore, no activating point mutations in the K-ras oncogene nor positive...... immunohistochemical staining for the p53 gene were observed in a set of 48 colon tumors. In conclusion, our results demonstrate that increased intake of lignan precursors from flaxseed or rye bran, administered in a Western-style diet, does not protect against intestinal tumor development in an appropriate animal...

    A novel isoform of a major rye grass pollen allergen Lol p 5 was isolated from a cDNA expression library. The new isoform, Lol p 5C, shares 95% amino acid sequence identity with Lol p 5A. Both isoforms demonstrated shared antigenic activity but different allergenic activities. Recombinant Lol p 5C demonstrated 100% IgE reactivity in 22 rye grass pollen sensitive patients. In comparison, recombinant Lol p 5A showed IgE reactivity in less than 64% of the patients. Therefore, Lol p 5C represents a novel and highly IgE-reactive isoform allergen of rye grass pollen.

  3. Effects of climate change on saltwater intrusion at Hilton Head Island, SC. U.S.A.

    2010-01-01

    Sea‐level rise and changes in precipitation patterns may contribute to the occurrence and affect the rate of saltwater contamination in the Hilton Head Island, South Carolina area. To address the effects of climate change on saltwater intrusion, a threedimensional, finite‐element, variable‐density, solute‐transport model was developed to simulate different rates of sea‐level rise and variation in onshore freshwater recharge. Model simulation showed that the greatest effect on the existing saltwater plume occurred from reducing recharge, suggesting recharge may be a more important consideration in saltwater intrusion management than estimated rates of sea‐level rise. Saltwater intrusion management would benefit from improved constraints on recharge rates by using model‐independent, local precipitation and evapotranspiration data, and improving estimates of confining unit hydraulic properties.

    A multicompartmental nontargeted LC–MS metabolomics approach was used to study the metabolic responses on plasma and urine of hypercholesterolemic pigs after consumption of diets with contrasting dietary fiber composition (whole grain rye with added rye bran versus refined wheat). To study...... the metabolic responses, we performed a supervised multivariate data analyses used for pattern recognition, which revealed marked effects of the diets on both plasma and urine metabolic profiles. Diverse pools of metabolites were responsible for the discrimination between the diets. Elevated levels of phenolic...... compounds and dicarboxylic acids were detected in urine of pigs after rye consumption compared to refined wheat. Furthermore, consumption of rye was characterized by lower levels of linoleic acid derived oxylipins and cholesterol in the plasma metabolic profiles. These results indicate that higher...

  6. Allelochemicals in rye (Secale cereale L.): cultivar and tissue differences in the production of benzoxazinoids and phenolic acids.

    2009-02-01

    In the present study, a range of benzoxazinoid compounds and phenolic acids, all known to be allelochemicals of rye, were identified and quantified in 13 rye cultivars grown at three different localities. Plant samples were collected in the spring at the time when an autumn-sown rye cover crop would be incorporated into the soil. Significant variations in content among shoots and roots were seen for all of the secondary metabolites, with non-methoxy-substituted benzoxazinoids (BX) dominating the shoots, whereas comparable levels were found in the concentrations of BX and methoxy-substituted benzoxazinoids (MBX) in the roots. This distribution of compounds may indicate different biosynthetic pathways and/or different mechanisms of action of these compounds. Concentrations not only depended on plant part, but also on the geographical location--with differences in contents of up to a factor of 5. These differences can probably be attributed to differences in growing conditions. The variation among cultivars was similar to that among geographical localities, with differences within localities of up to a factor of 7 in the shoots and a factor of 14 in the roots. In roots, the contents of the four phenolic acids and the benzoxazinoid 6-methoxybenzoxazolin-2-one (MBOA) were correlated. In shoots, the contents of the two benzoic acids were correlated with each other, whereas the two cinnamic acids were correlated with MBOA and several other benzoxazinoids. The lack of correlation between MBOA and all other benzoxazinoids in the roots of rye might indicate that a hitherto unknown synthetic pathway exists for MBOA. The genes responsible for the synthesis of some of the benzoxazinoids have never been identified, and further gene expression studies are required to assess the observed correlation between the concentration of these compounds and other benzoxazinoids for which the responsible genes are known. The present study revealed a potential for breeding rye cultivars with

    Gluten proteins in wheat, rye and barley cause celiac disease, an autoimmune disorder of the small intestine, which affects approximately 1% of the world population. Gluten is comprised of prolamin and glutelin. Since avoidance of dietary gluten is the only option for celiac patients, a sensitive gluten detection and quantitation method is warranted. Most regulatory agencies have set a threshold of 20 ppm gluten in foods labeled gluten-free, based on the currently available ELISA methods. However, these methods may exhibit differences in gluten quantitation from different gluten-containing grains. In this study, prolamin and glutelin fractions were isolated from wheat, rye, barley, oats and corn. Intact and pepsin-trypsin (PT)-digested prolamin and glutelin fractions were used to assess their immunoreactivity and gluten recovery by three sandwich and two competitive ELISA kits. The Western blots revealed varied affinity of ELISA antibodies to gluten-containing grain proteins and no reactivity to oat and corn proteins. ELISA results showed considerable variation in gluten recoveries from both intact and PT-digested gluten fractions among different kits. Prolamin fractions showed higher gluten recovery compared to their respective glutelin fractions. Among prolamins, barley exhibited higher recovery compared to wheat and rye with most of the ELISA kits used. Hydrolysis resulted in reduced gluten recovery of most gluten fractions. These results suggest that the suitability of ELISA for accurate gluten quantitation is dependent upon various factors, such as grain source, antibody specificity, gluten proteins and the level of their hydrolysis in foods.

  9. Effects of sea-level rise and pumpage elimination on saltwater intrusion in the Hilton Head Island area, South Carolina, 2004-2104

    Payne, Dorothy F.

    2010-01-01

    Saltwater intrusion of the Upper Floridan aquifer has been observed in the Hilton Head area, South Carolina since the late 1970s and currently affects freshwater supply. Rising sea level in the Hilton Head Island area may contribute to the occurrence of and affect the rate of saltwater intrusion into the Upper Floridan aquifer by increasing the hydraulic gradient and by inundating an increasing area with saltwater, which may then migrate downward into geologic units that presently contain freshwater. Rising sea level may offset any beneficial results from reductions in groundwater pumpage, and thus needs to be considered in groundwater-management decisions. A variable-density groundwater flow and transport model was modified from a previously existing model to simulate the effects of sea-level rise in the Hilton Head Island area. Specifically, the model was used to (1) simulate trends of saltwater intrusion from predevelopment to the present day (1885-2004) and evaluate the conceptual model, (2) project these trends from the present day into the future based on different potential rates of sea-level change, and (3) evaluate the relative influences of pumpage and sea-level rise on saltwater intrusion. Four scenarios were simulated for 2004-2104: (1) continuation of the estimated sea-level rise rate over the last century, (2) a doubling of the sea-level rise, (3) a cessation of sea-level rise, and (4) continuation of the rate over the last century coupled with an elimination of all pumpage. Results show that, if present-day (year 2004) pumping conditions are maintained, the extent of saltwater in the Upper Floridan aquifer will increase, whether or not sea level continues to rise. Furthermore, if all pumpage is eliminated and sea level continues to rise, the simulated saltwater extent in the Upper Floridan aquifer is reduced. These results indicate that pumpage is a strong driving force for simulated saltwater intrusion, more so than sea-level rise at current rates

    Full Text Available In this work, various sample preparation procedures, i.e., microwave-assisted acid digestion in a mixture of HNO3 and H2O2 solutions, solubilisation in aqua regia or tetramethyl ammonium hydroxide and extraction in diluted HNO3 or in HCl, for the determination of the total content of Ba, Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, P, Pb, Sr and Zn in rye crispbread using inductively coupled plasma optical emission spectrometry were compared. Analytical characteristic was evaluated by comparing the accuracy and precision of the results and limits of detection of elements. Among these five procedures solubilisation in aqua regia provides the best results, i.e., limits of detection of elements within 0.12–31.4 ng mL−1, precision of 0.4–5% and accuracy better than 5%. Additionally, a good agreement between the measured and certified values of the NIST 1567a was found for all elements. The proposed procedure is simple, reduces sample handling and minimises time and reagent consumption. Thus, it can be alternatively used instead of microwave-assisted acid digestion for routine analysis. Six different rye crispbreads were analysed with this procedure.

    Fructans are non-digestible carbohydrates with various nutritional properties including effects on microbial metabolism, mineral absorption and satiety. They are present in a range of plant foods, with wheat being an important source. The aim of the present study was to measure the fructan content of a range of wheat, rye and gluten-free breads consumed in the United Kingdom. Fructans were measured in a range of breads using selective enzymic hydrolysis and spectrophotometry based on the AOAC 999.03 method. The breads generally contained low quantities of fructan (0.61-1.94 g/100 g), with rye bread being the richest source (1.94 g/100 g). Surprisingly, gluten-free bread contained similar quantities of fructan (1.00 g/100 g) as other breads. There was wide variation in fructan content between individual brands of granary (0.76-1.09 g/100 g) and gluten-free breads (0.36-1.79 g/100 g). Although they contain only low quantities of fructan, the widespread consumption of bread may make a significant contribution to fructan intakes.

    The use of dietary fibers as fat-replacers in sausages gives less energy-dense and thereby healthier foods. Also, dietary fibers have been shown to induce satiety. The objectives of this study were to investigate if appetite sensations and energy intake was affected by (1) addition of dietary fibers to sausages, (2) type of dietary fibers and (3) the food matrix of the dietary fibers. In this randomized cross-over study 25 young men were served four test meals; wheat bran sausages, rye bran sausages, rye bran bread and wheat flour sausages. The test meals were served as breakfast after an overnight fast. Appetite sensations were evaluated by visual analogue scales (VAS) assessed every 30 min for 240 min followed by an ad libitum lunch meal where energy intake was calculated. Both rye bran and wheat bran sausages increased satiety (P appetite sensations and thereby has a potential added health benefit beyond the role as fat-replacer. The satisfying effect of dietary fibers appears to be more pronounced when added to sausages than when added to bread, stressing the importance of food matrix and food processing.

    Full Text Available Abstract Background The intake of dietary fibre has been shown to reduce the risk of developing diabetes mellitus. The aim of this study was to compare the effects of commercial rye whole-meal bread containing whole kernels and white wheat bread on the rate of gastric emptying and postprandial glucose response in healthy subjects. Methods Ten healthy subjects took part in a blinded crossover trial. Blood glucose level and gastric emptying rate (GER were determined after the ingestion of 150 g white wheat bread or 150 g whole-meal rye bread on two different occasions after fasting overnight. The GER was measured using real-time ultrasonography, and was calculated as the percentage change in antral cross-sectional area 15 and 90 minutes after completing the meal. Results No statistically significant difference was found between the GER values or the blood glucose levels following the two meals when evaluated with the Wilcoxon signed rank sum test. Conclusion The present study revealed no difference in postprandial blood glucose response or gastric emptying after the ingestion of rye whole-meal bread compared with white wheat bread.

    Dietary antioxidants that protect low-density lipoprotein (LDL) from oxidation may help to prevent atherosclerosis and coronary heart disease. The antioxidant activities of purified monomeric and dimeric hydroxycinnamates and of phenolic extracts from rye (whole grain, bran, and flour) were...... investigated using an in vitro copper-catalyzed human LDL oxidation assay. The most abundant ferulic acid dehydrodimer (diFA) found in rye, 8-O-4-diFA, was a slightly better antioxidant than ferulic acid and p-coumaric acid. The antioxidant activity of the 8-5-diFA was comparable to that of ferulic acid......, but neither 5-5-diFA nor 8-5-benzofuran-diFA inhibited LDL oxidation when added at 10-40 microM. The antioxidant activity of the monomeric hydroxycinnamates decreased in the following order: caffeic acid > sinapic acid > ferulic acid > p-coumaric acid. The antioxidant activity of rye extracts...

    Full Text Available The present study was undertaken to determine survival rate of Plodia interpunctella (Hübner, 1813, reared on different mechanical states of Vizija winter wheat cultivar and Raša winter rye cultivar, previously infested with different beetle pests. Wheat was previously infested with Rhyzopertha dominica, Sitophilus granarius, Oryzaephilus surinamensis and Cryptolestes ferrugineus, while rye was infested only with O. surinamensis. Kernels were tested in three different mechanical states: (A whole undamaged kernels; (B kernels already damaged by pests and (C original storage kernels (mixture of B and C type. No P. interpunctella adult emerged on wheat kernels, while 36 adults developed on rye kernels. The highest abundance reached beetle species who fed with a mixture of kernels damaged by pests and whole undamaged kernels. Development and survival rate of five different storage insect pests depends on type of kernels and there exist significant survivorship correlations among them.

  17. Sequence composition and gene content of the short arm of rye (Secale cereale chromosome 1.

    Silvia Fluch

    Full Text Available BACKGROUND: The purpose of the study is to elucidate the sequence composition of the short arm of rye chromosome 1 (Secale cereale with special focus on its gene content, because this portion of the rye genome is an integrated part of several hundreds of bread wheat varieties worldwide. METHODOLOGY/PRINCIPAL FINDINGS: Multiple Displacement Amplification of 1RS DNA, obtained from flow sorted 1RS chromosomes, using 1RS ditelosomic wheat-rye addition line, and subsequent Roche 454FLX sequencing of this DNA yielded 195,313,589 bp sequence information. This quantity of sequence information resulted in 0.43× sequence coverage of the 1RS chromosome arm, permitting the identification of genes with estimated probability of 95%. A detailed analysis revealed that more than 5% of the 1RS sequence consisted of gene space, identifying at least 3,121 gene loci representing 1,882 different gene functions. Repetitive elements comprised about 72% of the 1RS sequence, Gypsy/Sabrina (13.3% being the most abundant. More than four thousand simple sequence repeat (SSR sites mostly located in gene related sequence reads were identified for possible marker development. The existence of chloroplast insertions in 1RS has been verified by identifying chimeric chloroplast-genomic sequence reads. Synteny analysis of 1RS to the full genomes of Oryza sativa and Brachypodium distachyon revealed that about half of the genes of 1RS correspond to the distal end of the short arm of rice chromosome 5 and the proximal region of the long arm of Brachypodium distachyon chromosome 2. Comparison of the gene content of 1RS to 1HS barley chromosome arm revealed high conservation of genes related to chromosome 5 of rice. CONCLUSIONS: The present study revealed the gene content and potential gene functions on this chromosome arm and demonstrated numerous sequence elements like SSRs and gene-related sequences, which can be utilised for future research as well as in breeding of wheat and rye.

  18. Replication Improves Sorting-Task Results Analyzed by DISTATIS in a Consumer Study of American Bourbon and Rye Whiskeys.

    Lahne, Jacob; Collins, Thomas S; Heymann, Hildegarde

    2016-05-01

    In consumer food-sensory studies, sorting and closely related methods (for example, projective mapping) have often been applied to large product sets which are complex and fatiguing for panelists. Analysis of sorting by Multi-Dimensional Scaling (MDS) is common, but this method discards relevant individual decisions; analysis by DISTATIS, which accounts for individual differences, is gaining acceptance. This research posits that replication can improve DISTATIS analysis by stabilizing consumer sensory maps, which are often extremely unstable. As a case study a fatiguing product set was sorted: 10 American whiskeys-5 bourbons and 5 ryes-were sorted into groups by 21 consumers over 2 replications. These products were chosen because American whiskeys are some of the most important distilled beverages in today's market; in particular, "bourbon" (mashbill more than 50% corn) and "rye" (more than 50% rye) whiskeys are important and assumed to be products with distinct sensory attributes. However, there is almost no scientific information about their sensory properties. Data were analyzed using standard and aggregated DISTATIS and MDS. No significant relationship between mashbill and consumer categorization in whiskeys was found; instead, there was evidence of producer and aging effects. aggregated DISTATIS was found to provide more stable results than without replication, and DISTATIS results provided a number of benefits over MDS, including bootstrapped confidence intervals for product separation. In addition, this is the first published evidence that mashbill does not determine sensory properties of American whiskey: bourbons and ryes, while legally distinct, were not separated by consumers. © 2016 Institute of Food Technologists®

    One variety of barley and one variety of rye were taken to study the effect of gamma-radiation on pollen germination, pollen tube growth and seed set in barley-rye crosses. There was an increase in pollen germination and pollen tube growth over control at 1 kR dose but it was reduced at higher doses. Seed set was maximum at 1 kR and it was more than control from 1-5 kR. Only seeds of the cross Karan - 4 (1 kR)*MRSP-992 were able to germinate. In these germinated seeds the root growth was arrested after the fourth day of germination and they turned brown. The shoot growth was also very poor and it stopped after a week. (author) 11 refs.; 2 tabs

    2015-09-01

    Full Text Available In this study, the relationship between the inhibitory effects of extracts from rye-buckwheat ginger cakes supplemented with low and high rutin dosage baked without or with dough fermentation step on the formation of fluorescent advanced glycation end-products (AGEs, and phenolic compounds, rutin, D-chiro-inositol and antioxidant capacity were addressed. The cakes were based on rye flour substituted by light buckwheat flour or flour from roasted buckwheat groats at 30% level, and were produced with or without dough fermentation step. The inhibitory effect against AGEs formation was studied in bovine serum albumin (BSA-glucose and BSA-methylglyoxal (MGO systems. The antioxidant capacity was measured by 2,2-diphenyl- -1-picrylhydrazyl (DPPH and cyclic voltammetry (CV, rutin and D-chiro-inositol contents by HPLC and total phenolics (TPC by spectrophotometric assays. The study showed the inhibitory effects of extracts from rye-buckwheat ginger cakes supplemented with low and high rutin dosage. The results of the inhibitory activity were highly correlated in two applied model systems. Enrichment of rye-buckwheat ginger cakes with rutin improved their antioxidant properties. The correlation studies showed that the inhibitory effects of rye-buckwheat ginger cakes produced with dough fermentation step and enhanced with rutin against formation of AGEs were highly correlated with TPC, rutin and D-chiro-inositol contents, and antioxidant capacity. Moreover, the effect of rutin enrichment was clearly seen in cakes obtained with dough fermentation step, even the inhibitory activity was slightly lower as compared to the cakes produced without dough fermentation.

    Full Text Available Abstract Background Rye products have been demonstrated to lower the acute insulin demand, induce a low and prolonged blood glucose response (high Glycemic Profile, GP and reduce subclinical inflammation. These products may therefore contribute to a lowered risk of obesity, type 2 diabetes and cardio vascular disease. The objective of the present paper was to evaluate the mechanism for a reduced postprandial insulin demand with rye products, and to explore possible appetite regulating properties. Methods 10 healthy subjects were served breakfast meals (50 g of available starch with endosperm- or whole grain rye breads, with and without lactic acid, boiled whole grain rye- (RK or wheat (WK kernels, or white wheat bread reference (WWB in random order in a cross-over design. Plasma concentrations of glucose, ghrelin, serum insulin, free fatty acids, adiponectin, breath hydrogen excretion (H2, and subjective satiety was evaluated during the postprandial phase. 270 min after the breakfast, an ad lib lunch buffet was served and the voluntary energy intake (EI was registered. Results All rye products and WK induced lower insulinemic indices (II than WWB. A lower incremental insulin peak following breakfast correlated with a lower EI at lunch (r = 0.38. A low II was related to improved satiety in the early postprandial phase (fullness AUC 0-60 min, r = -0.36. RK induced a higher GP compared to WWB and WK. A higher GP was related to a lowered desire to eat before lunch (AUC 210-270 and to a lower concentration of ghrelin in the late postprandial phase after breakfast (270 min, r = -0.29 and -0.29, which in turn was related to a lower voluntary EI (r = 0.43 and 0.33. The RK breakfast improved satiety in the early postprandial phase (0-60 min compared to WWB, and induced a lower EI at lunch (-16%. A high content of indigestible carbohydrates in the breakfast products was related to improved satiety (0-60 min, r = 0.68 for fullness, and a higher breath H2

    The aim of this study was to find out the effect of selected spices on chemical and sensorial markers in cakes formulated on rye and light buckwheat flour fortified with spices. Among collection of spices, rye-buckwheat cakes fortified individually with cloves, nutmeg, allspice, cinnamon, vanilla, and spice mix revealed the highest sensory characteristics and overall quality. Cakes fortified with cloves, allspice, and spice mix showed the highest antioxidant capacity, total phenolics, rutin, and almost threefold higher available lysine contents. The reduced furosine content as well as free and total fluorescent intermediatory compounds were observed as compared to nonfortified cakes. The FAST index was significantly lowered in all cakes enriched with spices, especially with cloves, allspice, and mix. In contrast, browning index increased in compare to cakes without spices. It can be suggested that clove, allspice, vanilla, and spice mix should be used for production of safety and good quality cakes.

    The complete amino acid sequence of two "isoallergenic" forms of Lol p I, the major rye grass (Lolium perenne) pollen allergen, was deduced from cDNA sequence analysis. cDNA clones isolated from a Lolium perenne pollen library contained an open reading frame coding for a 240-amino acid protein. Comparison of the nucleotide and deduced amino acid sequence of two of these clones revealed four changes at the amino acid level and numerous nucleotide differences. Both clones contained one possible asparagine-linked glycosylation site. Northern blot analysis shows one RNA species of 1.2 kilobases. Based on the complete amino acid sequence of Lol p I, overlapping peptides covering the entire molecule were synthesized. Utilizing these peptides we have identified a determinant within the Lol p I molecule that is recognized by human leukocyte antigen class II-restricted T cells obtained from persons allergic to rye grass pollen.

    Benzoxazinoids are secondary metabolites with plant defense properties and possible health-promoting effects in humans. In this study, the transcriptional activity of ScBx genes (ScBx1-ScBx5; ScBx6-like), involved in benzoxazinoid biosynthesis, was analyzed during germination and early seedling...... development in rye. Our results showed that ScBx genes had highest levels of expression at 24–30 h after germination, followed by a decrease at later stages. For ScBx1-ScBx5 genes expression was higher in shoots compared with root tissues and vice versa for ScBx6-like gene transcripts. Moreover, methylated...

    Extractable dietary fiber (DF) plays an important role in nutrition. This study on porridge making with whole grain rye investigated the effect of rest time of flour slurries at room temperature before cooking and amount of flour and salt in the recipe on the content of DF components and molecular weight distribution of extractable fructan, mixed linkage (1→3)(1→4)-β-d-glucan (β-glucan) and arabinoxylan (AX) in the porridge. The content of total DF was increased (from about 20% to 23% of dry matter) during porridge making due to formation of insoluble resistant starch. A small but significant increase in the extractability of β-glucan (P = 0.016) and AX (P = 0.002) due to rest time was also noted. The molecular weight of extractable fructan and AX remained stable during porridge making. However, incubation of the rye flour slurries at increased temperature resulted in a significant decrease in extractable AX molecular weight. The molecular weight of extractable β-glucan decreased greatly during a rest time before cooking, most likely by the action of endogenous enzymes. The amount of salt and flour used in the recipe had small but significant effects on the molecular weight of β-glucan. These results show that whole grain rye porridge made without a rest time before cooking contains extractable DF components maintaining high molecular weights. High molecular weight is most likely of nutritional importance.

    Whole-grain foods and cereal dietary fiber intake is associated with lower body weight. This may partly result from lower energy utilization of high-fiber diets. In the present study, the impact on ileal excretion of energy and macronutrients in response to a rye bread high-fiber diet compared to a refined wheat low-fiber diet was investigated. Furthermore, the effect of meal frequency on apparent absorption of nutrients was studied for the first time. Ten participants that had undergone ileostomy consumed standardized iso-caloric diets, including low-fiber wheat bread (20 g dietary fiber per day) for 2 weeks followed by high-fiber rye bread (52 g dietary fiber per day) for 2 weeks. The diets were consumed in an ordinary (three meals per day) and a nibbling (seven meals per day) meal frequency in a cross-over design. Ileal effluents were collected during 24 h at the third day of each of the four dietary periods and analyzed for gross energy and nutrient contents. The results showed that intake of rye bread high-fiber diet compared to the refined wheat low-fiber diet caused an increase in ileal excretion of energy and macronutrients. The effect was independent of meal frequency. This suggests that a high intake of rye may result in lower availability of macronutrients for small intestinal digestion and absorption. A regular intake of rye may therefore have implications for weight management.

  13. Lysergic acid amide as chemical marker for the total ergot alkaloids in rye flour - Determination by high-performance thin-layer chromatography-fluorescence detection.

    2017-07-21

    Ergot alkaloids are generally determined by high-performance liquid chromatography (HPLC) coupled to fluorescence detection (FLD) or mass selective detection, analyzing the individual compounds. However, fast and easy screening methods for the determination of the total ergot alkaloid content are more suitable, since for monitoring only the sum of the alkaloids is relevant. The herein presented screening uses lysergic acid amide (LSA) as chemical marker, formed from ergopeptine alkaloids, and ergometrine for the determination of the total ergot alkaloids in rye with high-performance thin-layer chromatography-fluorescence detection (HPTLC-FLD). An ammonium acetate buffered extraction step was followed by liquid-liquid partition for clean-up before the ergopeptine alkaloids were selectively transformed to LSA and analyzed by HPTLC-FLD on silica gel with isopropyl acetate/methanol/water/25% ammonium hydroxide solution (80:10:3.8:1.1, v/v/v/v) as the mobile phase. The enhanced native fluorescence of LSA and unaffected ergometrine was used for quantitation without any interfering matrix. Limits of detection and quantitation were 8 and 26μg LSA/kg rye, which enables the determination of the total ergot alkaloids far below the applied quality criterion limit for rye. Close to 100% recoveries for different rye flours at relevant spiking levels were obtained. Thus, reliable results were guaranteed, and the fast and efficient screening for the total ergot alkaloids in rye offers a rapid alternative to the HPLC analysis of the individual compounds.

  14. Town mouse or country mouse: identifying a town dislocation effect in Chinese urbanization.

    Directory of Open Access Journals (Sweden)

    Fei Wang

    Full Text Available Understanding urbanization and evaluating its impact are vital for formulating global sustainable development. The results obtained from evaluating the impact of urbanization, however, depend on the kind of measurement used. With the goal of increasing our understanding of the impact of urbanization, we developed direct and indirect subjective indicators to measure how people assess their living situation. The survey revealed that the projected endorsements and perceived social ambiance of people toward living in different types of settlements did not improve along with the urbanization level in China. The assessment scores from the city dwellers were not significantly different from those from the country areas and, more surprisingly, both were significantly higher than the assessment scores of the town dwellers, which we had expected to fall between the assessment scores of the country and city dwellers. Instead their scores were the lowest. We dubbed this V-shaped relationship the "town dislocation effect." When searching for a potential explanation for this effect, we found additional town dislocation effects in social support, loss aversion, and receptivity toward genetically modified food. Further analysis showed that only social support mediated the relationship between the three tiers of settlements (cities, country areas, and towns and the subjective indicator. The projected endorsements yielded significant subjective assessments that could enhance our understanding of Chinese urbanization. Towns posed specific problems that require special attention.

    Rye (Secale cerealis) has been widely cultivated to improve soil quality in temperate paddies. However, its biomass incorporation can significantly increase greenhouse gas emissions, particularly the emission of methane (CH{sub 4}), during rice cultivation. The chemical composition and productivity of cover crop biomass may vary at different growing stages. Therefore, nutrient productivity and CH{sub 4} production potential might be controlled by selecting the optimum harvesting stage. To investigate the effect of rye harvesting stage on nutrient productivity and CH{sub 4} production potential, rye was harvested at different growing stages, from the flowering stage to the maturing stage, for seven weeks. The chemical composition and biomass productivity of rye were investigated. CH{sub 4} production was measured by laboratory incubation, and CH{sub 4} production potential was estimated to determine the real impact on CH{sub 4} dynamics in rice soils. Rye biomass increased with plant maturation, but nutrient productivities such as N (nitrogen), P{sub 2}O{sub 5}, and K{sub 2}O were maximized at the flowering stage. The contents of cellulose and lignin increased significantly as plants matured, but the total N, labile organic carbon (C), and hot and cold water-extractable organic C clearly decreased. Soils were mixed with 0.3% (wt wt{sup −1} on dry weight) air-dried biomass and incubated to measure the maximum CH{sub 4} productivity at 30 °C under flooded conditions. Maximum CH{sub 4} productivity was significantly correlated with increasing labile organic C and protein content, but it was negatively correlated with total organic C, cellulose, and lignin content. CH{sub 4} production potentials were significantly increased up to the pre-maturing stage (220 DAS) and remained unchanged thereafter. As a result, CH{sub 4} production potential per N productivity was the lowest at the late flowering stage (198–205 DAS), which could be the best harvesting stage as well

    Rye (Secale cerealis) has been widely cultivated to improve soil quality in temperate paddies. However, its biomass incorporation can significantly increase greenhouse gas emissions, particularly the emission of methane (CH_4), during rice cultivation.

    High-performance liquid chromatography was used to study the stability of folate vitamers in two types of rye breads after baking and 16 weeks of frozen storage. Bread made using sourdough seeds contained less total folate (74.6 microg/100 g dry basis, expressed as folic acid) than the whole rye flour (79.8 microg/100 g dry basis) and bread leavened only with baker's yeast (82.8 microg/100 g dry basis). Most importantly, it was generated by a significant decrease in 5-CH3-H4folate form. The baking process caused some changes in folate distribution. Storage of breads at -18 degrees C for 2 weeks did not have a significant effect (p type of breads. After a longer period of storage (16 weeks), a 25% loss of folates in the bread made with baker's yeast and a 38% loss in the bread fermented with sourdough seeds was found. Retention of 5-CH3-H4folate and 10-HCO-H2folate forms were much lower in the bread made with a sourdough addition than with baker's yeast only.

    Whole rye (WR) consumption seems to be associated with beneficial health effects. Although rye fiber and polyphenols are thought to be bioactive, the mechanisms behind the health effects of WR have yet to be fully identified. This study in rats was designed to investigate whether WR can influence the metabolism of n-3 and n-6 long-chain fatty acids (LCFA) and gut microbiota composition. For 12 weeks, rats were fed a diet containing either 50% WR or 50% refined rye (RR). The WR diet provided more fiber (+21%) and polyphenols (+29%) than the RR diet. Fat intake was the same in both diets and particularly involved similar amounts of essential (18-carbon) n-3 and n-6 LCFAs. The WR diet significantly increased the 24-hour urinary excretion of polyphenol metabolites-including enterolactone-compared with the RR diet. The WR rats had significantly more n-3 LCFA-in particular, eicosapentanoic (EPA) and docosahexanoic (DHA) acids-in their plasma and liver. Compared with the RR diet, the WR diet brought significant changes in gut microbiota composition, with increased diversity in the feces (Shannon and Simpson indices), decreased Firmicutes/Bacteroidetes ratio and decreased proportions of uncultured Clostridiales cluster IA and Clostridium cluster IV in the feces. In contrast, no difference was found between groups with regards to cecum microbiota. The WR rats had lower concentrations of total short-chain fatty acids (SCFA) in cecum and feces (pconsumption results in major biological modifications-increased plasma and liver n-3 EPA and DHA levels and improved gut microbiota profile, notably with increased diversity-known to provide health benefits. Unexpectedly, WR decreased SCFA levels in both cecum and feces. More studies are needed to understand the interactions between whole rye (fiber and polyphenols) and gut microbiota and also the mechanisms of action responsible for stimulating n-3 fatty acid metabolism.

    In a stratified random sample of 320 white adults, the prevalence of puncture skin test positivity (ST +) to Lolium perenne (rye grass)-pollen extract (LPE) was 16%. Fifteen percent of all subjects (or 84% of subjects classified LPE IgE antibody positive [Ab +]) was classified IgE Ab + to highly purified Lol p I (Rye I), and 4% of all subjects (or 26% of subjects classified LPE IgE Ab +) was classified IgE Ab + to highly purified Lol p II (Rye II). These data and similar results obtained in an allergy-enriched group of 361 subjects are consistent with previous studies that Lol I is a major allergen and Lol II is a minor allergen of LPE. Whether we studied LPE, Lol I, or Lol II, responder subjects were younger than nonresponder subjects and more male than female subjects were responders. We then investigated the quantitative interrelationships among ST, IgE, and IgG Ab responsiveness to LPE, Lol I, and Lol II in the allergy-enriched group. For each allergen, log-log correlations were strong and significant for ST versus IgE Ab and for IgE Ab versus IgG Ab. All subjects IgE Ab + to Lol I or Lol II were IgG Ab + to that allergen, supporting other evidence for a commonality in the genetic control influencing the production of IgE and IgG Abs to a given allergen. Log-log correlations among ST end points, IgE Ab levels, or IgG Ab levels were strong for LPE versus either Lol I or Lol II but weak between Lol I and Lol II, consistent with the reported lack of cross-reactivity between Lol I and Lol II. Despite these findings, almost all Lol II + subjects were Lol I + by ST (98%), IgE Ab (91%), and IgG Ab (83%), suggesting that the Ia-restricted immune recognition of both these molecules is at least in part under a common genetic control.

  4. Transfer of genes for stem rust resistance from Agropyron elongatum and imperial rye to durum wheat

    Prabhakara Rao, M.V.

    1977-01-01

    The Agropyron elongatum gene for stem rust resistance on chromosome 6A of Knott's Thatcher translocation line was transferred to a susceptible local durum wheat variety, Jaya, through a series of back-crosses. Plants heterozygous for the Agropyron translocation always show at least one open bivalent. Homozygotes have not been obtained, probably because of the absence of male transmission in durum background. Monotelosomic addition of the short arm of Imperial rye chromosome 3R (formerly ''G'' of Sears), which carries a gene(s) for resistance to wheat stem rust, was obtained in the local durum variety. Rust-resistant plants from parents having the added rye telocentric were irradiated with gamma rays just before meiosis, and the pollen obtained from the irradiated spikes was used to pollinate euploid plants. In addition, seeds harvested from 2n+1 resistant plants were irradiated with thermal neutrons and the resistant M 1 plants were selfed to raise M 2 families. Two durum-rye translocation lines were obtained following irradiation. DRT-1 was transmitted normally through the female gametes but showed no male transmission. As a result of this, homozygotes have not been obtained. Gametic transmission rates of DRT-2 are being tested. Alien translocations, which show normal gametic and zygotic transmissions in the hexaploid wheat, may behave differently in a tetraploid background. The results indicate that alien genetic transfers may be more difficult to obtain in durum wheat, probably owing to the reduced buffering effect of the tetraploid genome. (author)

    The color of grain in cereals is determined mainly by anthocyanin pigments. A large level of genetic diversity for anthocyanin content and composition in the grain of different species was observed. In rye, recessive mutations in six genes (vi1...vi6) lead to the absence of anthocyanins in all parts of the plant. Moreover, dominant genes of anthocyanin synthesis in aleurone (gene C) and pericarp (gene Vs) also affect the color of the grain. Reverse phase high-performance liquid chromatography and mass spectrometry were used to study anthocyanins in 24 rye samples. A lack of anthocyanins in the lines with yellow and brown grain was determined. Delphinidin rutinoside and cyanidin rutinoside were found in the green-seeded lines. Six samples with violet grains significantly varied in terms of anthocyanin composition and content. However, the main aglycone was cyanidin or peonidin in all of them. Monosaccharide glucose and disaccharide rutinose served as the glycoside units. Violet-seeded accession forms differ in the ratio of the main anthocyanins and the range of their acylated derivatives. The acyl groups were presented mainly by radicals of malonic and sinapic acids. For the colored forms, a profile of the revealed anthocyanins with the indication of their contents was given. The obtained results are discussed in connection to similar data in rice, barley, and wheat, which will provide a perspective for future investigations.

    Background Bread types with high contents of whole grains and rye are associated with beneficial health effects. Consumer characteristics of different bread consumption patterns are however not well known. Objective To compare bread consumption patterns among Swedish adults in relation to selected socio-demographic, geographic, and lifestyle-related factors. For selected consumer groups, the further aim is to investigate the intake of whole grains and the context of bread consumption, that is, where and when it is consumed. Design Secondary analysis was performed on bread consumption data from a national dietary survey (n=1,435). Respondents were segmented into consumer groups according to the type and amount of bread consumed. Multiple logistic regressions were performed to study how selected socio-demographic, geographic, and lifestyle-related factors were associated with the consumer groups. Selected consumption groups were compared in terms of whole-grain intake and consumption context. Consumption in different age groups was analysed more in detail. Results One-third of the respondents consumed mainly white bread. Socio-demographic, geographic, and healthy-lifestyle-related factors were associated with the bread type consumed. White bread consumption was associated with younger age groups, less education, children in the family, eating less fruit and vegetables, and more candy and snacks; the opposite was seen for mainly whole-grain bread consumers. Older age groups more often reported eating dry crisp bread, whole-grain bread, and whole-grain rye bread with sourdough whereas younger respondents reported eating bread outside the home, something that also mainly white bread eaters did. Low consumers of bread also consumed less whole grain in total. Conclusions Traditional bread consumption structures were observed, as was a transition among young consumers who more often consumed fast food bread and bread outside the home, as well as less rye and whole

To compare bread consumption patterns among Swedish adults in relation to selected socio-demographic, geographic, and lifestyle-related factors. For selected consumer groups, the further aim is to investigate the intake of whole grains and the context of bread consumption, that is, where and when it is consumed. Secondary analysis was performed on bread consumption data from a national dietary survey (n=1,435). Respondents were segmented into consumer groups according to the type and amount of bread consumed. Multiple logistic regressions were performed to study how selected socio-demographic, geographic, and lifestyle-related factors were associated with the consumer groups. Selected consumption groups were compared in terms of whole-grain intake and consumption context. Consumption in different age groups was analysed more in detail. One-third of the respondents consumed mainly white bread. Socio-demographic, geographic, and healthy-lifestyle-related factors were associated with the bread type consumed. White bread consumption was associated with younger age groups, less education, children in the family, eating less fruit and vegetables, and more candy and snacks; the opposite was seen for mainly whole-grain bread consumers. Older age groups more often reported eating dry crisp bread, whole-grain bread, and whole-grain rye bread with sourdough whereas younger respondents reported eating bread outside the home, something that also mainly white bread eaters did. Low consumers of bread also consumed less whole grain in total. Traditional bread consumption structures were observed, as was a transition among young consumers who more often consumed fast food bread and bread outside the home, as well as less rye and whole-grain bread.

    The potential of utilising exhaled breath volatile organic compound (VOC) profiles in studying diet-derived metabolic changes was examined. After a four-week initial diet period with white wheat bread (WW), seven participants received in randomised order high-fibre diets containing sourdough whole grain rye bread (WGR) or white wheat bread enriched with bioprocessed rye bran (WW + BRB), both for 4 weeks. Alveolar exhaled breath samples were analysed with ChemPro ® 100i analyser (Environics OY, Mikkeli, Finland) at the end of each diet period in fasting state and after a standardised meal. The AIMS signal intensities in fasting state were different after the WGR diet as compared to other diets. The result suggests that WGR has metabolic effects not completely explained by the rye fibre content of the diet. This study encourages to utilise the exhaled breath VOC profile analysis as an early screening tool in studying physiological functionality of foods.

    2017-11-08

    Kinetic parameters for the dephosphorylation of sodium phytate and a series of partially phosphorylated myo-inositol phosphates were determined at pH 3.0 and pH 5.0 for three phytase preparations (Aspergillus niger, Escherichia coli, rye). The enzymes showed lower affinity and turnover numbers at pH 3 compared to pH 5 toward all myo-inositol phosphates included in the study. The number and distribution of phosphate groups on the myo-inositol ring affected the kinetic parameters. Representatives of the individual phytate dephosphorylation pathways were identified as the best substrates of the phytases. Within the individual phytate dephosphorylation pathways, the pentakisphosphates were better substrates compared to the tetrakisphosphates or phytate itself. E. coli and rye phytase showed comparable activities at both pH values toward the tetrakis- and trisphosphate, whereas A. niger phytase exhibited a higher activity toward the tetrakisphosphate. A myo-inositol phosphate with alternate phosphate groups was shown to be not significantly dephosphorylated by the phytases.

    Impact of water extractable arabinoxylan from rye bran on frozen steamed bread dough quality was investigated in terms of the bread characteristics, ice crystallization, yeast activity as well as the gluten molecular weight distribution and glutenin macropolymer content in the present study. Results showed that water extractable arabinoxylan significantly improved bread characteristics during the 60-day frozen storage. Less water was crystallized in the water extractable arabinoxylan dough during storage, which could explain the alleviated yeast activity loss. For all the frozen dough samples, more soluble high molecular weight (Mw ≈ 91,000-688,000) and low molecular weight (Mw ≈ 91,000-16,000) proteins were derived from glutenin macropolymer depolymerization. Nevertheless, water extractable arabinoxylan dough developed higher glutenin macropolymer content with lowered level of soluble low molecular weight proteins throughout the storage. This study suggested water extractable arabinoxylan from rye bran had great potential to be served as an effective frozen steamed bread dough improver. Copyright © 2016 Elsevier Ltd.

    The Midwestern United States, a region that produces one-third of maize and one-quarter of soybeans globally, is projected to experience increasing rainfall variability with future climate change. One approach to mitigate climate impacts is to utilize crop and soil management practices that enhance soil water storage, reducing the risks of flooding and runoff as well as drought-induced crop water stress. While some research indicates that a winter cover crop in a maize-soybean rotation increases soil water, producers continue to be concerned that water use by cover crops will reduce water for a following cash crop. We analyzed continuous in-field soil moisture measurements over from 2008-2014 at a Central Iowa research site that has included a winter rye cover crop in a maize-soybean rotation for thirteen years. This period of study included years in the top third of wettest years on record (2008, 2010, 2014) as well as years in the bottom third of driest years (2012, 2013). We found the cover crop treatment to have significantly higher soil water storage from 2012-2014 when compared to the no cover crop treatment and in most years greater soil water content later in the growing season when a cover crop was present. We further found that the winter rye cover crop significantly increased the field capacity water content and plant available water compared to the no cover crop treatment. Finally, in 2012 and 2013, we measured maize and soybean biomass every 2-3 weeks and did not see treatment differences in crop growth, leaf area or nitrogen uptake. Final crop yields were not statistically different between the cover and no cover crop treatment in any of the years of this analysis. This research indicates that the long-term use of a winter rye cover crop can improve soil water dynamics without sacrificing cash crop growth.

Design: Ten participants that had undergone ileostomy consumed standardized iso-caloric diets, including low-fiber wheat bread...... (20 g dietary fiber per day) for 2 weeks followed by high-fiber rye bread (52 g dietary fiber per day) for 2 weeks. The diets were consumed in an ordinary (three meals per day) and a nibbling (seven meals per day) meal frequency in a cross-over design. Ileal effluents were collected during 24 h...... was independent of meal frequency. This suggests that a high intake of rye may result in lower availability of macronutrients for small intestinal digestion and absorption. A regular intake of rye may therefore have implications for weight management....

  20. Candidate Genes for Aggressiveness in a Natural Fusarium culmorum Population Greatly Differ between Wheat and Rye Head Blight

    Directory of Open Access Journals (Sweden)

    Valheria Castiblanco

    2018-01-01

    Full Text Available Fusarium culmorum is one of the species causing Fusarium head blight (FHB in cereals in Europe. We aimed to investigate the association between the nucleotide diversity of ten F. culmorum candidate genes and field ratings of aggressiveness in winter rye. A total of 100 F. culmorum isolates collected from natural infections were phenotyped for FHB at two locations and two years. Variance components for aggressiveness showed significant isolate and isolate-by-environment variance, as expected for quantitative host-pathogen interactions. Further analysis of the isolate-by-environment interaction revealed the dominant role of the isolate-by-year over isolate-by-location interaction. One single-nucleotide polymorphism (SNP in the cutinase (CUT gene was found to be significantly (p < 0.001 associated with aggressiveness and explained 16.05% of the genotypic variance of this trait in rye. The SNP was located 60 base pairs before the start codon, which suggests a role in transcriptional regulation. Compared to a previous study in winter wheat with the same nucleotide sequences, a larger variation of pathogen aggressiveness on rye was found and a different candidate gene was associated with pathogen aggressiveness. This is the first report on the association of field aggressiveness and a host-specific candidate gene codifying for a protein that belongs to the secretome in F. culmorum.

  1. Proportionality in enterprise development of South African towns

    Directory of Open Access Journals (Sweden)

    Maitland T. Seaman

    2012-05-01

    Full Text Available We investigated proportionalities in the enterprise structures of 125 South African towns through examining four hypotheses, (1 the magnitude of enterprise development in a town is a function of the population size of the town; (2 the size of an enterprise assemblage of a town is a function of the town’s age; (3 there are statistically significant relationships, and hence proportionalities, between the total number of enterprises in towns and some, if not all, of the enterprise numbers of different business sectors in towns; and (4 the implications of proportionalities have far-reaching implications for rural development and job creation. All hypotheses were accepted on the basis of statistically significant (p < 0.05 correlations, except for the second hypothesis – the age of a town does not determine the size of its enterprise assemblage. Analysis for the fourth hypothesis suggested that there are two broad entrepreneurial types in South African towns: ‘run-of-the-mill’ entrepreneurs and ‘special’ entrepreneurs, which give rise to different enterprise development dynamics. ‘Run-of-the-mill’ enterprises are dependent on, and limited by, local demand and if there is only a small demand, the entrepreneurial space is small. By comparison, ‘special’ enterprises have much larger markets because their products and/or services are exportable. We propose that the fostering of ‘special’ entrepreneurs is an imperative for local economic development in South African towns.

    Daniel P Johansson

    Full Text Available Whole grain rye products have been shown to increase satiety and elicit lower postprandial insulin response without a corresponding change in glucose response compared with soft refined wheat bread. The underlying mechanisms for these effects have not been fully determined The primary aim of the study was to investigate if whole grain rye crisp bread compared to refined wheat crisp bread, elected beneficial effects on appetite and postprandial insulin response, similarly as for other rye products.In a randomized cross-over trial, 23 healthy volunteers, aged 27-70 years, BMI 18-31.4 kg/m2, were served a standardized breakfast with unfermented whole grain rye crisp bread (uRCB, fermented whole grain rye crisp bread (RCB or refined wheat crisp bread (WCB, Appetite was measured using a visual analogue scale (VAS until 4 h after breakfast. Postprandial glucose and insulin were measured at 0-230 min. Breads were chemically characterized including macronutrients, energy, dietary fiber components, and amino acid composition, and microstructure was characterized with light microscopy.Reported fullness was 16% higher (P<0.001, and hunger 11% and 12% lower (P<0.05 after ingestion of uRCB and RCB, respectively, compared with WCB. Postprandial glucose response did not differ significantly between treatments. Postprandial insulin was 10% lower (P<0.007 between 0-120 min but not significantly lower between 0-230 min for RCB compared with WCB. uRCB induced 13% (P<0.002 and 17% (P<0.001 lower postprandial insulin response between 0-230 min compared with RCB and WCB respectively.Whole grain rye crisp bread induces higher satiety and lower insulin response compared with refined wheat crisp bread. Microstructural characteristics, dietary fiber content and composition are probable contributors to the increased satiety after ingestion of rye crisp breads. Higher insulin secretion after ingestion of RCB and WCB compared with uRCB may be due to differences in fiber

    The youngest Lithuanian town surrounded by pine forest is situated at the shore of a picturesque lake of Visaginas. The level of radiation of the town and its suburbs doesn't prevail the standards due to the data given by the Lithuanian Department of Environmental Protection. A relatively small, hilly, green, full of lakes areas have all facilities for tourism and recreation. The town's birth is directly linked with the construction of the nuclear power plant. Great number of nuclear energy specialists came here with their families from the East. The specific character of the town determined the ethnic composition of its population. In 1994-1995 there were Russians (59%), Lithuanians (14%), Byelorussian s (11%), Poles (6%), other nationalities (10%). The number of the residents in Visaginas is stable now with a slight tendency of increasing on the number of women. In 1990 the population of Visaginas was 33192, the women comprised 566 more in number than the men, in 1997 of its 33508 people were 1172 more women than the men. Recent Lithuanian social-economic changes greatly influenced the number of inhabitants of the town. In 1987, 3567 new inhabitants arrived to Visaginas and 1588 moved out. The inhabitants who had arrived to Visaginas in 1987 -1996 were 5,5 times less than in 1987, and moved out 5,4 times less also. One half of the inhabitants who moved from Visaginas went abroad. It shows that the mechanic and social mobility of the town's population decreased too. From 1989 to 1996 the main factor in changing the population number was not the natural increase of it but its migration. Then the natural increase lowered 4,8 times. The economic situation of the town is complex and becoming worse. The town was built as a satellite of the power plant. When the construction of the third block was stopped, the building of many objects was not completed. Other industries didn't develop in Visaginas. Most unemployed are the inhabitants at the age of 19-49 (87,9%). The

    Town gas plant sites are receiving increasing attention from the utility industry and regulatory communities. This attention has been prompted by greater environmental awareness of impacts due to past disposal practices and the understanding that gas plant wastes contain a wide range of chemical constituents that have persisted in the environment. This paper discusses the history of the town gas plant industry, the various processes utilized and the resultant by-products and wastes. Potential problem areas relating to these sites as well as potential approaches to site characterization are addressed. Included are recommendations for the phasing of site investigations and the use of relatively inexpensive and rapid field screening techniques to identify contamination

    Full Text Available The Triticum timopheevi cytoplasmic male sterility (cms system in triticale (xTriticosecale Wittmack suffers from a low frequency of maintainers and environmental instability of the male sterility. On the other hand, the Pampa cms system in rye (Secale cereale exhibits strong male sterility and a low frequency of restorers. Here, we report generating hybrids between maintainers of the T. timopheevi cms system in triticale and maintainers of the rye Pampa cms system. Ten hybrids were obtained. Their hybridity was verified by PCR (polymerase chain reaction using ISSR (inter simple sequence repeats primers. The cms maintaining ability of F2 individuals and their progeny was tested. The F2 plants were crossed to male sterile lines of triticale carrying the T. timopheevi cytoplasm. Among 180 G1 offspring of these crosses, 71 (39.4% were completely male sterile. Fourteen F2 individuals (7.8%, as well as their F2S1 and progeny, generated stable male sterility in G1, G1BC1 and G1BC2 generations after the crosses. Our results suggest that it is possible to produce a more stable cms system in triticale based on the T. timopheevi cytoplasm as compared to the existing one.

    Rye (Secale cerealis) has been widely cultivated to improve soil quality in temperate paddies. However, its biomass incorporation can significantly increase greenhouse gas emissions, particularly the emission of methane (CH4), during rice cultivation. The chemical composition and productivity of cover crop biomass may vary at different growing stages. Therefore, nutrient productivity and CH4 production potential might be controlled by selecting the optimum harvesting stage. To investigate the effect of rye harvesting stage on nutrient productivity and CH4 production potential, rye was harvested at different growing stages, from the flowering stage to the maturing stage, for seven weeks. The chemical composition and biomass productivity of rye were investigated. CH4 production was measured by laboratory incubation, and CH4 production potential was estimated to determine the real impact on CH4 dynamics in rice soils. Rye biomass increased with plant maturation, but nutrient productivities such as N (nitrogen), P2O5, and K2O were maximized at the flowering stage. The contents of cellulose and lignin increased significantly as plants matured, but the total N, labile organic carbon (C), and hot and cold water-extractable organic C clearly decreased. Soils were mixed with 0.3% (wt wt(-1) on dry weight) air-dried biomass and incubated to measure the maximum CH4 productivity at 30 °C under flooded conditions. Maximum CH4 productivity was significantly correlated with increasing labile organic C and protein content, but it was negatively correlated with total organic C, cellulose, and lignin content. CH4 production potentials were significantly increased up to the pre-maturing stage (220 DAS) and remained unchanged thereafter. As a result, CH4 production potential per N productivity was the lowest at the late flowering stage (198-205 DAS), which could be the best harvesting stage as well as the most promising stage for increasing nutrient production and decreasing GHG

    The objective of this study was to determine the efficiency of rye and barley starch hydrolysis in mashing processes using cereal malts as a source of amylolytic enzymes and starch, and to establish the volatile profile of the obtained agricultural distillates. In addition, the effects of the pretreatment method of unmalted cereal grains on the physicochemical composition of the prepared mashes, fermentation results, and the composition of the obtained distillates were investigated. The raw materials used were unmalted rye and barley grains, as well as the corresponding malts. All experiments were first performed on a semi-technical scale, and then verified under industrial conditions in a Polish distillery. The fermentable sugars present in sweet mashes mostly consisted of maltose, followed by glucose and maltotriose. Pressure-thermal treatment of unmalted cereals, and especially rye grains, resulted in higher ethanol content in mashes in comparison with samples subjected to pressureless liberation of starch. All agricultural distillates originating from mashes containing rye and barley grains and the corresponding malts were characterized by low concentrations of undesirable compounds, such as acetaldehyde and methanol. The distillates obtained under industrial conditions contained lower concentrations of higher alcohols (apart from 1-propanol) than those obtained on a semi-technical scale.

    Full Text Available Vegetative coverage is commonly used to reduce urban slope soil erosion. Laboratory experimental study on soil erosion under grass covered slopes is conventionally time and space consuming. In this study, a new method is suggested to study the influences of vegetation coverage on soil erosion from a sloped loess surface under three slope gradients of 5°, 15°, and 25°; four rye grass coverages of 0%, 25%, 50%, and 75%; and three rainfall intensities of 60, 90, and 120 mm/h with a silt-loamy loess soil. Rye grasses were planted in the field with the studied soil before being transplanted into a laboratory flume. Grass was allowed to resume growth for a period before the rain simulation experiment. Results showed that the grass cover reduced soil erosion by 63.90% to 92.75% and sediment transport rate by 80.59% to 96.17% under different slope gradients and rainfall intensities. The sediment concentration/sediment transport rate from bare slope was significantly higher than from a grass-covered slope. The sediment concentration/transport rate from grass-covered slopes decreased linearly with grass coverage and increased with rainfall intensity. The sediment concentration/transport rate from the bare slope increased as a power function of slope and reached the maximum value at the gradient of about 25°, whereas that from grass-covered slope increased linearly and at much lower levels. The results of this study can be used to estimate the effect of vegetation on soil erosion from loess slopes.

    The conversion of lignocellulose to valuable products requires I: a fractionation of the major components hemicellulose, cellulose, and lignin, II: an efficient method to process these components to higher valued products. The present work compares liquid hot water (LHW) pretreatment to the soda pulping process and to the ethanol organosolv pretreatment using rye straw as a single lignocellulosic material. The organosolv pretreated rye straw was shown to require the lowest enzyme loading in order to achieve a complete saccharification of cellulose to glucose. At biomass loadings of up to 15% (w/w) cellulose conversion of LHW and organosolv pretreated lignocellulose was found to be almost equal. The soda pulping process shows lower carbohydrate and lignin recoveries compared to the other two processes. In combination with a detailed analysis of the different lignins obtained from the three pretreatment methods, this work gives an overview of the potential products from different pretreatment processes.

  6. Leading Communities: Community-led Development in England’s Small Towns: the Market Towns Initiative

    Directory of Open Access Journals (Sweden)

    Gordon Morris

    2012-12-01

    Full Text Available The Market Towns Initiative (MTI, a UK community-led development programme, operated throughout rural England from 2000 until 2005/6. It was designed to help local people, with professional support, identify – and then capitalize on – the economic, environmental and social strengths and weaknesses of small country towns. This paper explains the origins and ways of working of the MTI. Examples of the topics explored and participants’ views are given, and conclusions drawn. The opportunity is also taken to explain how interest in the roles of England’s small country towns grew in the years following the Second World War, and how this led to the development of the MTI. Evidence suggests that the programme worked well. It demonstrated that local people have the enthusiasm, skills and knowledge to take a lead in the development of the places in which they live; something which, until local government reforms changed roles and structures, was largely taken for granted.

    The present study was undertaken in order to investigate the suitability of certain markers for UV plant response. In addition, we attempted to link the internal tissue distribution of specific UV-absorbing compounds to profiles of radiation gradients within intact primary rye leaves (Secale cereale L. cv. Kustro). Etiolated rye seedlings irradiated with low visible light (LL) and/or UV radiation were used to study enzyme activities of the two key enzymes, phenylalanine ammonia-lyase (PAL) and chalcone synthase (CHS), together with the tissue-specific accumulation of soluble phenylpropanoid products. Plants grown under relatively high visible light (HL) with or without supplementary UV-B radiation were used for further characterization. Apparent quantum yield and fluorescence quenching parameters were monitored to assess potential physiological changes due to UV-B exposure in HL-grown seedlings. A quartz fibreoptic microprobe was used to characterize the internal UV-B gradient of the leaf. The response of the phenylpropanoid metabolism to UV radiation was similar in primary leaves of both etiolated and HL-treated green plants. The epidermis-specific flavonoids together with CHS activity turned out to be suitable markers for assessing the effect of UV on the phenolic metabolism. The functional role of phenylpropanoid compounds was strongly implicated in protecting rye from UV-B radiation

    Full Text Available The article provides progress report on the barley of F3к-10029/Saratovske 4 height decreasing throughout 1974 to 2012 by way of selecting plants of the shortest stem. 38 years of selecting the shortest stem genotypes cut down plant height by 5,7 times at the background of dominant Hl gene expression. Average plant height during 38 breeding cycles was descending by 2,69 cm, but this was not an even trend. New creative donor for ultimate short stem characteristic, Gnome 3, has been developed, with Hl-3Hl-3alleles designation. Relative impact on the efficacy of minus-selection by the plant height of the selection differential (38,00% and inheritance coefficient in its narrow sense (14,56% is established. Efficiency of the selection is realized with the decrease of winter rye height plants by 72,08% as expected by the relative breeding forecast. Analyzes is completed for 11 genetic and statistical clusters of average utilitarian characteristics of Gnome 3 ultra short stem rye over the period from 1974 to 2012.

    The bread-making process influences bread components, including phenolics that significantly contribute to its antioxidant properties. Five bread model systems made from different rye cultivars were investigated to compare their impact on concentration of ethanol-soluble (free and ester-bound) and insoluble phenolics. Breads produced by a straight dough method without acid addition (A) and three-stage sourdough method with 12 h native starter preparation (C) exhibited the highest, genotype-dependent concentrations of free phenolic acids. Dough acidification by direct acid addition (method B) or by gradual production during prolonged starter fermentation (24 and 48 h, for methods D and E) considerably decreased their level. However, breads B were enriched in soluble ester-bound fraction. Both direct methods, despite substantial differences in dough pH, caused a similar increase in the amount of insoluble ester-bound fraction. The contents of phenolic fractions in rye bread were positively related to activity level of feruloyl esterase and negatively to those of arabinoxylan-hydrolysing enzymes in wholemeal flour. The solubility of rye bread phenolics may be enhanced by application of a suitable bread-making procedure with respect to rye cultivar, as the mechanisms of this process are also governed by a response of an individual genotype with specific biochemical profile. © 2014 The Authors.

    Dalitz, R.H.

    1988-01-01

    Tony Hilton Royle Skyrme was born on 5 December 1922 at 7 Blessington Road, Lewisham (Kent), London. Tony's maternal grandfather was Herbert William Thomson Roberts, a tidal computer for the Admiralty by profession. The inclusion of Lord Kelvin's baptismal name (William Thomson) among his forenames reflects the professional contact which Tony's great-grandfather had with Lord Kelvin and the high regard in which he held the latter. This great-grandfather of Tony's on the maternal side was Edward Roberts. He was appointed Secretary to the Tidal Committee of the British Association for the Advancement of Science, being made responsible later for the construction of the first Tidal Predicter, which had been designed by Lord Kelvin. He played a large part in the design and construction of the Universal Tide-predicting Machines used by the Indian and Colonial Government and by the Admiralty Hydrographic Office. It was his house which held the Tidal Predicter, the first model of the machine, which made such a strong impression on the young Tony and influenced so greatly the development of his later ideas, as Tony himself recounted in a lecture given at a Workshop on Skyrmions in 1984

  19. Methods of Services Provision in Slovak Towns

    Directory of Open Access Journals (Sweden)

    Emília Sičáková-Beblavá

    2009-07-01

    Full Text Available This article deals with the methods of services provision in Slovak towns.  It addresses decision-making concerning selected services provision, based on a transaction cost economic model. The article looks at five types of services from that point of view. These are core services, i.e., services that are provided in most Slovak towns, thereby allowing outcomes of decision-making to be compared, and services which can be outsourced according to transaction cost theory. Findings partially confirm the hypothesis: Slovak towns do outsource, though “insourcing” moderately prevails. However, a comparison of several research studies in the area indicates a trend towards higher outsourcing of such local services provision.  The findings show that public bodies do not always select the most suitable methods of services provision, as suggested by the transaction costs theory (the Brown-Potoski model. This indicates that it is not only economic models that influence decision-making concerning the organization of services provision in the Slovak towns.

    B chromosomes (Bs) are dispensable components of the genomes of numerous species. Thus far, there is a lack of evidence for any transcripts of Bs in plants, with the exception of some rDNA sequences. Here, we show that the Giemsa banding-positive heterochromatic subterminal domain of rye (Secale cereale) Bs undergoes decondensation during interphase. Contrary to the heterochromatic regions of A chromosomes, this domain is simultaneously marked by trimethylated H3K4 and by trimethylated H3K27, an unusual combination of apparently conflicting histone modifications. Notably, both types of B-specific high copy repeat families (E3900 and D1100) of the subterminal domain are transcriptionally active, although with different tissue type–dependent activity. No small RNAs were detected specifically for the presence of Bs. The lack of any significant open reading frame and the highly heterogeneous size of mainly polyadenylated transcripts indicate that the noncoding RNA may function as structural or catalytic RNA.

    The complete amino acid sequence of a Lolium perenne (rye grass) pollen allergen, Lol p II was determined by automated Edman degradation of the protein and selected fragments. Cleavage of the protein by enzymatic and chemical techniques established an unambiguous sequence for the protein. Lol p II contains 97 amino acid residues, with a calculated molecular weight of 10,882. The protein lacks cysteine and glutamine and shows no evidence of glycosylation. Theoretical predictions by Fraga's (Fraga, S. (1982) Can. J. Chem. 60, 2606-2610) and Hopp and Woods' (Hopp, T. P., and Woods, K. R. (1981) Proc. Natl. Acad. Sci. U.S.A. 78, 3824-3828) methods indicate the presence of four hydrophilic regions, which may contribute to sequential or parts of conformational B-cell epitopes. Analysis of amphipathic regions by Berzofsky's method indicates the presence of a highly amphipathic region, which may contain, or contribute to, an Ia/T-cell epitope. This latter segment of Lol p II was found to be highly homologous with an antibody-binding segment of the major rye allergen Lol p I and may explain why immune responsiveness to both the allergens is associated with HLA-DR3.

    The emission of N{sub 2}O from the soil has a significant impact on the greenhouse gas balance of energy crops. Soil type, temperature, precipitation, tillage practice and level of fertilization may affect the source strength of N{sub 2}O emissions and fertilizer-induced N{sub 2}O emissions. The N{sub 2}O-fluxes from different sites of an experimental field were measured by the flux chamber method over a period of four years (2003-2006). Poplar and rye as one perennial and one annual crop were fertilized at levels of 0 kg N ha{sup -1} yr{sup -1}, 75 kg N ha{sup -1} yr{sup -1} and 150 kg N ha{sup -1} yr{sup -1}. Enhanced N{sub 2}O emission spots with maxima of up to 1653 {mu}g N{sub 2}O m{sup -2} h{sup -1} were observed at fertilized sites for several weeks. The emissions ranged between 0.4 kg N{sub 2}O-N ha{sup -1} yr{sup -1} and 2.7 kg N{sub 2}O-N ha{sup -1} yr{sup -1} depending on fertilization level, crop variety and year. The mean conversion factor was 2.1% for poplar and 0.9% for rye. The CO{sub 2}-advantage of energy crops is reduced by N{sub 2}O emissions by up to 10%. (author)

  5. Food Policing in Early Modern Danish Towns

    Directory of Open Access Journals (Sweden)

    Jørgen Mührmann-Lund

    2016-08-01

    Full Text Available This article explores the efforts of early modern authorities to provide food security in three different Danish towns in order to understand the goals and methods of early modern food policing. As in other European countries, urban authorities were expected as part of the regulation called ‘the police’ to control the guilds and fix the prices on bread, meat, beer and other life necessities in order to avoid scarcity among the urban poor. In 1682–83 the Danish king established a police force in Copenhagen and the other market towns. The goal of the metropolitan police was to increase the population of the capital and thus increase the military-fiscal power of the absolutist state, by providing food security and even a comfortable life. In practice, the vigilant policing of bakers, butchers and brewers proved difficult. The positive economic effect of food policing was doubted early on and was reduced as a means to avoid food riots at the end the 18th century. In a major provincial market town like Aalborg, the food trade was policed in a similar manner by the town council and the police, but especially the intermediate trade proved difficult to stop. In a tiny, agrarian market town like Sæby, food policing was more a question of feeding the poor with the town’s own products.

    This study used a standardized, dialyzed, Lolium perenne (ryegrass) pollen extract and two of its well-characterized components, Lol p I (Rye I) and Lol p II (Rye II), to characterize the longitudinal variation of both IgE and IgG antibody (Ab) levels, as well as total serum IgE levels, in 20 grass-allergic subjects followed for 13 months. Ab levels declined toward a basal level just before, and increased just after, the grass-pollination season, returning to the same basal level just before the next grass-pollination season. The least complex allergen, Lol II, demonstrated the most uniform pattern of variation in both IgE and IgG Ab levels. Total serum IgE levels demonstrated the least regular pattern of variation. Grass-pollen counts were strongly correlated with symptom-medication scores for these subjects (rs = 0.87). Initial values were correlated with the rise in total IgE and IgE Ab to Lol II across the grass-pollen season. Skin test results were correlated with initial IgE Ab levels for L. perenne pollen extract and Lol II. Finally, a procedure for correcting IgE Ab levels to basal values was proposed and tested. The correction procedure, for each IgE Ab, was based on the average rise during the grass-pollination season (or average decline after the grass-pollination season) observed for all subjects with that IgE Ab.

  11. Trends in population growth in China's towns during the eighties, and town population in-migration and its decisive factors: a historic convergence of two types of demographic change.

    Relying on socioeconomic and population statistics, as well as population censuses, the author examines the growth of China's towns in the 1980s due to in-migration, and considers the economic causes and impact of the growth of towns. Prior to 1984, China's urbanization had been slow and uneven. But in the 4 years from 1984-87, China's urban population grew 3.8 times faster than the period before 1984. and unlike the previous pattern of urbanization, slightly over half of the urban growth occurred in small cities and towns. The rapid growth of towns was due to an unprecedented level of in-migration into towns from agricultural villages. This population transformed itself into a nonagricultural population. The author attributes the increase in urbanization and its changing patterns to a historic convergence: the shift in industry for the agricultural population and a regional shift for the village population--realized through a form of village-to-town population migration. The author goes on to examine the development of small-town enterprises, facilitated after the rural reform of 1984. The author notes that since that year, small-town industries have flourished, a development that has had a number of beneficial effects on both the provincial areas and the nation as a whole. Finally, the author considers the factors that have fueled town population in-migration: 1) in most provinces, higher incomes in towns have attracted people from the villages; and 2) in provinces with little discrepancy in income between town and village, a combination of the regions' relative isolation and government policy preventing migration to cities have spurred the growth of towns.

    Crop calenders used to determine when Earth Resources Technology Satellite ERTS data would provide the most accurate wheat acreage information and to minimize the amount of ground verified information needed are presented. Since barley, oats, and rye are considered 'confusion crops, i.e., hard to differentiate from wheat in ERTS imagery, specific dates are estimated for these crops in the following stages of development: (1) seed-bed operation, (2) planting or seeding, (3) intermediate growth, (4) dormancy, (5) development of crop to full ground cover, (6) heading or tasseling, and flowering, (7) harvesting, and (8) posting-harvest operations. Dormancy dates are included for fall-snow crops. A synopsis is given of each states' growing conditions, special cropping practices, and other characteristics which are helpful in identifying crops from ERTS imagery.

    Sourdough is a food item made by kneading grain flour and water together and allowing fermentation through the action of lactic acid bacteria (Lactobacillales) and yeast. Typically, Japanese bakeries make sourdough with rye flour, wheat flour, malt extract, and water and allow spontaneous fermentation for 6 days. We compared the microbial behavior and food components, such as organic acids, sugars, and free amino acids, of sourdoughs made using two different rye and wheat flours during the 6-day fermentation period. Comparisons were made for two types of rye and wheat flours, using different production sites and different milling, distribution, and storage conditions. The microbial count was evaluated using different culture media. All sourdough types showed a significant increase in lactic acid levels on fermentation day 2 and a decrease in free amino acid levels on day 4. Low overall lactic acid production and little fluctuation in sugar levels occurred in sourdough made from French ingredients. For sourdough made from Japanese ingredients, sugar levels (chiefly glucose, sucrose, and maltose) declined on fermentation day 1, increased on day 2, and declined by day 5. With the French ingredients, no yeast cells were detected until day 3, and many acid precursors of sourdough flavor components were detected. Yet with the Japanese ingredients, 10 6 /g yeast cells were detected on days 3-5, as well as sourdough-flavor esters and alcohols. Differences in raw material quality affected the microbial behavior and changes in food constituents during the fermentation process and, consequently, the sourdough flavor.

  16. Promoting small towns for rural development: a view from Nepal.

    Bajracharya, B N

    1995-06-01

    Two small villages in Nepal are the subjects of case studies that illustrate the role of small towns in provision of services, employment, and market operations. Some general findings are that small towns act as service centers for distribution of basic essential goods such as food grains, salt, kerosene, and fabric for hill and mountain areas. The role of small towns as market centers and in the provision of employment is limited. In resource-poor areas small towns are less diversified. Towns with agricultural surpluses are more developed. Small hill towns satisfy consumption rather than production needs. The growth of rural areas and towns in rural areas in Nepal is dependent on arable land and levels of production in hill areas. Limited land and low levels of production have an adverse impact. Movement of people, goods, and services is limited by difficult terrain and lack of access to good roads. Variability in access to off-farm jobs and services available in small towns varies with ethnicity and place of residence. The best development strategy for small towns in Nepal is market-oriented territorial development, which retains surpluses in the local area and integrates markets in the larger economy. The strategy would decentralize planning into small territorial units that include both small towns and groups of villages, provide institutional support for the rural poor, expand off-farm employment, and include investment in region-serving functions. Subsistence agriculture needs to include diversification of high value cash crops based on local comparative advantage suitable for hill climate and terrain. Small farmers must produce both cash and subsistence crops. Government should provide market space and paved areas, weighing facilities, and overnight storage facilities. Products would be processed at the village level. Subdistricts must be established according to spatial and social linkages between villages and the service center and coordinated at the

    Full Text Available Self-promotion and reinterpretation of local identity is becoming increasingly important in rural communities. Local identity building is succeeded very differently by rural municipalities and regions. The paper analyses the role of small towns in local identity creation. There are varying interpretations of places in Hungary as ways of achieving meaningful territorialisation. Small towns based on their leading and central position within the micro regions can dominate the place-making processes. Using the example of six Hungarian rural micro-regions we analyse how rural small towns position themselves by local image building. The aim of this paper is to investigate interactions between territorial position and innovative capacity of rural towns through the analysis of symbolisation process and image building. We purpose to introduce a concept of a place oriented approach and demonstrate its usefulness for analysis of rural innovation and place-based development. The case-studies are based on qualitative methods: document-analysis, semi-structured interviews, transect walking and participatory observation. The paper analyses the process of local community and identity building in six rural micro-regions. We seek to understand how small towns position themselves in place-making, the aim of ‘placing’ themselves in the territorial hierarchy of the settlements of micro region. Our results suggest that small towns play very different roles in local image building. Characteristics and territorial scope of local cultural heritage significantly determine the innovative capacity of small towns in local image building where there is a wide range of meanings procedures and processes of place-making.

    2016-09-01

    Full Text Available This analysis investigates medium-sized towns in Poland, i.e. those with a population between 20–100 thousand, located up to 100 km away from the main city of the agglomeration. The aim of this article is to compare the level of socio-economic development of Polish towns depending on their location in relation to the main city in the largest agglomerations in 1998 and 2013. Three zones of distance from the main city of each agglomeration have been taken into consideration: a. the inner zone, reaching up to 25 km from the main city; b. the outer zone located at a distance of 25 to 50 km from the main city, and c. the peripheral zone, located at a distance of 50 to 100 km from the main city and including the medium-size towns located outside the agglomeration system. This analysis of the distribution of medium-sized towns and their level of socio-economic development has shown various levels of changes which depend on the distance from the main city of the agglomeration. In 1998, the highest level of development of the medium-sized towns was recorded in towns outside of these agglomeration systems, i.e. those located most remotely from the main city (peripheral zone. Most of the medium-sized towns are situated at a distance of 50–100 km from Warszawa, Kraków, Łódź, Lublin, Gdańsk and have developed their own local, or even regional labour markets and some of them have even provided administrative functions in the past as voivodeship capitals. Only in the Poznań agglomeration, the level of development of medium-sized towns was higher in the immediate surroundings of the main city (25 km. The medium-sized towns in all zones of the distance from the main city in the Wrocław agglomeration represented a similar level of development. By 2013, the level of development of the medium-sized towns in the peripheral zone in all investigated settlement systems had decreased, with a significant improvement in the level of development of the towns in

    1988-04-01

    A seventeenth-century merchant and nonconformist from Rye in Sussex, Samuel Jeake had a passionate interest in astrology. In his diary--recently recovered in Los Angeles and published here for the first time--Jeake not only recorded the events of his life; he subjected them to astrological scrutiny, interspersing his text with horoscopes. The result is one of the most interesting 17th-century diaries to be published in many years, throwing important light on the history of astrology, commerce, medicine, and religion. An illuminating introduction by the editors places the diary in the context of the preoccupations and priorities of Jeake's age.

    2014-01-01

    The evolution of bacterial consortia was studied in six semi-solid rye sourdoughs during long-term backslopping at different temperatures. Each rye sourdough was started spontaneously in a laboratory (dough yield 200), propagated at either 20°C or 30°C, and renewed daily at an inoculation rate of 1∶10 for 56 days. The changes in bacterial diversity over time were followed by both DGGE coupled with partial 16S rRNA gene sequencing and pyrosequencing of bar-coded 16S rRNA gene amplicons. Four species from the genus Lactobacillus (brevis, crustorum, plantarum, and paralimentarius) were detected in different combinations in all sourdoughs after 56 propagation cycles. Facultative heterofermentative lactic acid bacteria dominated in sourdoughs fermented at 30°C, while both obligate and facultative heterofermentative LAB were found to dominate in sourdoughs fermented at 20°C. After 56 propagation cycles, Kazachstania unispora (formerly Saccharomyces unisporus) was identified as the only yeast species that dominated in sourdoughs fermented at 20°C, while different combinations of strains from four yeast species (Kazachstania unispora, Saccharomyces cerevisiae, Candida krusei and Candida glabrata) were detected in sourdoughs propagated at 30°C. The evolution of bacterial communities in sourdoughs fermented at the same temperature did not follow the same time course and changes in the composition of dominant and subdominant bacterial communities occurred even after six weeks of backslopping.

  10. Adapting adaptation: the English eco-town initiative as governance process

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Climate change adaptation and mitigation have become key policy drivers in the UK under its Climate Change Act of 2008. At the same time, urbanization has been high on the agenda, given the pressing need for substantial additional housing, particularly in southeast England. These twin policy objectives were brought together in the UK government's 'eco-town' initiative for England launched in 2007, which has since resulted in four eco-town projects currently under development. We critically analyze the eco-town initiative's policy evolution and early planning phase from a multilevel governance perspective by focusing on the following two interrelated aspects: (1 the evolving governance structures and resulting dynamics arising from the development of the eco-town initiative at UK governmental level, and the subsequent partial devolution to local stakeholders, including local authorities and nongovernmental actors, under the new 'localism' agenda; and (2 the effect of these governance dynamics on the conceptual and practical approach to adaptation through the emerging eco-town projects. As such, we problematize the impact of multilevel governance relations, and competing governance strategies and leadership, on shaping eco-town and related adaptation strategies and practice.

  11. Myo-inositol hexakisphosphate degradation by Bifidobacterium pseudocatenulatum ATCC 27919 improves mineral availability of high fibre rye-wheat sour bread.

    2015-07-01

    The goal of this investigation was to develop baking products using Bifidobacterium pseudocatenulatum ATCC27919, a phytase producer, as a starter in sourdough for the production of whole rye-wheat mixed bread. This Bifidobacterium strain contributed to myo-inositol hexakisphosphate (phytate) hydrolysis, resulting in breads with higher mineral availability as was predicted by the phytate/mineral molar ratios, which remained below the inhibitory threshold values for Ca and Zn intestinal absorption. The products with sourdough showed similar technological quality as their homologous without sourdough, with levels of acetic and d/l lactic acids in dough and bread baking significantly higher with the use of sourdough. The overall acceptability scores showed that breads with 25% of whole rye flour were highly accepted regardless of the inclusion of sourdough. This work emphasises that the in situ production of phytase during fermentation by GRAS/QPS microorganisms constitutes a strategy which is particularly appropriate for reducing the phytate contents in products for human consumption.

    International Nuclear Information System (INIS)

    Kocher, B.S.; Azzam, F.O.; Lee, S.

    1994-01-01

    Town gas sites represent a large environmental problem that exists in more than 2,000 sites across North America alone. The major contaminants in town gas sods are polycyclic aromatic hydrocarbons (PAHs). These are stable compounds that migrate deep into the soil and are traditionally very difficult to remove by conventional remediation processes. Supercritical fluids offer enhanced solvating properties along with reduced mass transfer resistances that make them ideal for removing compounds that are difficult or impossible to remove by conventional processes. Supercritical water is ideal for removing PAHs and other hydrocarbons from soil due to its high solvating power towards most hydrocarbon species. Supercritical water was investigated for its ability to remediate two different town gas sods containing from 3--20 wt% contamination. The sod was remediated in a 300-cc semi-continuous system to a more environmentally acceptable level

    Full Text Available The article proves that the genetic cluster analysis using of parents – offspring system at the period of 38 generations of directional intentional selection to short stem, the height of winter rye plants has been reduced less than 90 cm with simultaneously productivity integral components increasing. Directional selection on parent plants short stem has revealed pleiotropic effects to increasing averages of productivity yield capacity, spike length, flowers number, grains, and short stem and simultaneously its productivity reducing, plant and weight reducing of 100 direct descendants grains. Plant height donor of short stem Gnome 1 has been controlled prevailing by genetic factors and has been less influenced by environmental conditions. Selection by enlargement of elite plants grains has predetermined genetically increasing of the average height of families in the next generation without the concept selection requirements satisfaction. Therefore, the directed selections, by the structural analysis results, are annually held in two phases, first – to the expressed short stem and then among of them – to the high weight of 100 grains per plant and desirable productivity elements. A creative dominant short stem donor with stems up to 90 cm and a weight of 100 grains per plant more than 4.0 g has been made. A short stem spike shortness donor Dwarf 1possesses a significant reserve of common genetic mutation of quantitative characteristics, which can be used by direct and indirect selection. This population has been represented by its large amount, in order to enhance capabilities of directional selection plants short stem providing with the desired productivity components during the studying. Informative additive genetic cluster analysis is high. Plants productivity is considered to be extremely complicated selection characteristics, including many component constituents parts related genetically.

    Full Text Available To evaluate the role of effective factors on competition of two wheat cultivars against two species of narrow leaf and broad leaf weeds this study was conducted as two separated experiments based on a randomized complete block design with 3 replications at Agricultural Faculty of Bu-Ali Sina University, in 2008-2009. In both Experiments, Alvand and Sayson cultivars were planted with densities of 450 plants m-2. In the 1st experiment, rye with densities of 0, 20, 40, 60 and 80 plants m-2 were planted in inter-rows of wheat. In the 2nd experiment, wild mustard densities were 0, 8, 16, 24 and 32 plants m-2. The results showed that characters such as vertical distribution of leaf area index and dry matter, height and its increase rate in interference, emergence rate, rate of canopy development and precocity led to increasing competitive ability of Alvand than Sayson in competition with two weed species. These factors were effective in reduction seed production of weeds and economic threshold in Alvand. Despite of lower height of wild mustard than rye, distribution of leaf area and canopy structure of wild mustard increased light competition ability and shadow on crop, so that harmful effects of individual plant of wild mustard in different densities was more than rye. Increasing rate of wild mustard seed bank was more than ray.

    Full Text Available Visaginas, formerly Sniečkus, (Lithuania was built as a planned socialist town and a satellite settlement to the Ignalina Nuclear Power Plant. Both the plant and the town were established in order to integrate Lithuania into the All-Union economic structures via the energy supply system,. The specific characteristics of the town were a particular mono industry, high living standards, ethnic composition (mostly Russian speaking migrants, Lithuanians as minority, absence of any history prior to 1973 and strong pro-Soviet attitudes. For years, it was a success story and the vanguard site of the socialism. After the declaration of Lithuanian Independency in 1990, the town became the site of tensions and uncertainties. The aim of this research study is to illuminate how post-Soviet transition has been experienced by this particular type of community shaped by socialism. Community experiences are retrospectively reconstructed via content analysis of the local media. The particular characteristics of the town (ethnic composition, employment structure, etc. made the process of transition extremely complicated. While other planned socialist towns established new identities and new trajectories of development, in the case of Visaginas, not the future, but the past played a crucial role in shaping the town’s identity.

  18. Impact of grazing dairy steers on winter rye (Secale cereale versus winter wheat (Triticum aestivum and effects on meat quality, fatty acid and amino acid profiles, and consumer acceptability of organic beef.

    Directory of Open Access Journals (Sweden)

    Hannah N Phillips

    Full Text Available Meat from Holstein and crossbred organic dairy steers finished on winter rye and winter wheat pastures was evaluated and compared for meat quality, fatty acid and amino acid profiles, and consumer acceptability. Two adjacent 4-ha plots were established with winter rye or winter wheat cover crops in September 2015 at the University of Minnesota West Central Research and Outreach Center (Morris, MN. During spring of 2015, 30 steers were assigned to one of three replicate breed groups at birth. Breed groups were comprised of: Holstein (HOL; n = 10, crossbreds comprised of Montbéliarde, Viking Red, and HOL (MVH; n = 10, and crossbreds comprised of Normande, Jersey, and Viking Red (NJV; n = 10. Dairy steers were maintained in their respective replicate breed group from three days of age until harvest. After weaning, steers were fed an organic total mixed ration of organic corn silage, alfalfa silage, corn, soybean meal, and minerals until spring 2016. Breed groups were randomly assigned to winter rye or winter wheat and rotationally grazed from spring until early summer of 2016. For statistical analysis, independent variables were fixed effects of breed, forage, and the interaction of breed and forage, with replicated group as a random effect. Specific contrast statements were used to compare HOL versus crossbred steers. Fat from crossbreds had 13% greater omega-3 fatty acids than HOL steers. Furthermore, the omega-6/3 ratio was 14% lower in fat from crossbreds than HOL steers. For consumer acceptability, steaks from steers grazed on winter wheat had greater overall liking than steers grazed on winter rye. Steak from crossbreeds had greater overall liking than HOL steers. The results suggest improvement in fatty acids and sensory attributes of beef from crossbred dairy steers compared to HOL steers, as well as those finished on winter wheat compared to winter rye.

    Meat from Holstein and crossbred organic dairy steers finished on winter rye and winter wheat pastures was evaluated and compared for meat quality, fatty acid and amino acid profiles, and consumer acceptability. Two adjacent 4-ha plots were established with winter rye or winter wheat cover crops in September 2015 at the University of Minnesota West Central Research and Outreach Center (Morris, MN). During spring of 2015, 30 steers were assigned to one of three replicate breed groups at birth. Breed groups were comprised of: Holstein (HOL; n = 10), crossbreds comprised of Montbéliarde, Viking Red, and HOL (MVH; n = 10), and crossbreds comprised of Normande, Jersey, and Viking Red (NJV; n = 10). Dairy steers were maintained in their respective replicate breed group from three days of age until harvest. After weaning, steers were fed an organic total mixed ration of organic corn silage, alfalfa silage, corn, soybean meal, and minerals until spring 2016. Breed groups were randomly assigned to winter rye or winter wheat and rotationally grazed from spring until early summer of 2016. For statistical analysis, independent variables were fixed effects of breed, forage, and the interaction of breed and forage, with replicated group as a random effect. Specific contrast statements were used to compare HOL versus crossbred steers. Fat from crossbreds had 13% greater omega-3 fatty acids than HOL steers. Furthermore, the omega-6/3 ratio was 14% lower in fat from crossbreds than HOL steers. For consumer acceptability, steaks from steers grazed on winter wheat had greater overall liking than steers grazed on winter rye. Steak from crossbreeds had greater overall liking than HOL steers. The results suggest improvement in fatty acids and sensory attributes of beef from crossbred dairy steers compared to HOL steers, as well as those finished on winter wheat compared to winter rye.

    of fermentable wort carbohydrates were observed in the worts (all at ca. 12°P), and in particular oat wort had lower concentration of maltose compared to the others, resulting in the lowest concentration of alcohol in final beer. Moreover, wort made from unmalted grains also showed lower free amino nitrogen......Whilst beers have been produced using various levels of unmalted grains as adjuncts along with malt, brewing with 100 % unmalted grains in combination with added mashing enzymes remains mostly unknown. The aim of this study was to investigate the brewing potential of 100 % unmalted barley, wheat......, oat and rye in comparison with 100 % malt. To address this, identical brewing methods were adopted at 10-L scale for each grain type by applying a commercial mashing enzyme blend (Ondea® Pro), and selected quality attributes were assessed for respective worts and beers.

  1. Challenges and prospects of Danish service towns in the new urban geography

    DEFF Research Database (Denmark)

    Fertner, Christian; Groth, Niels Boje

    2012-01-01

    Many small towns in Denmark lost population and functions in recent decades. The service towns established between 1850 and 1940 take a considerable share of those. In that time almost 500 new towns emerged all over the country to serve the new export-oriented agricultural production as regional...... service centres. This development was accompanied by new communication and transport technologies including railways, which gave the towns the Danish name “stationsby” (“station town”). Many experienced rapid growth in population and economic activities, which first levelled off with the crisis...... of the 1930s and later with the introduction of the car as dominant mode of transport. After a municipal reform in 1970, some of the railway towns became administrative centres in the new larger municipalities followed by a pronounced growth. However, most of the service towns are still very small: 40 % have...

    The subject of this article is the possibilities of the documentation of a defunct town from the Pre-Islamic period to Early Islamic period. This town is located near the town Makhmur in Iraq. The Czech archaeological mission has worked at this dig site. This Cultural Heritage site is threatened by war because in the vicinity are positions of ISIS. For security reasons, the applicability of Pleiades satellite data has been tested. Moreover, this area is a no-fly zone. However, the DTM created from stereo-images was insufficient for the desired application in archeology. The subject of this paper is the testing of the usability of RPAS technology and terrestrial photogrammetry for documentation of the remains of buildings. RPAS is a very fast growing technology that combines the advantages of aerial photogrammetry and terrestrial photogrammetry. A probably defunct church is a sample object.

    2011-10-01

    Full Text Available Abstract Background The mechanism behind the lowered postprandial insulin demand observed after rye bread intake compared to wheat bread is unknown. The aim of this study was to use the metabolomics approach to identify potential metabolites related to amino acid metabolism involved in this mechanism. Methods A sourdough fermented endosperm rye bread (RB and a standard white wheat bread (WB as a reference were served in random order to 16 healthy subjects. Test bread portions contained 50 g available carbohydrate. In vitro hydrolysis of starch and protein were performed for both test breads. Blood samples for measuring glucose and insulin concentrations were drawn over 4 h and gastric emptying rate (GER was measured. Changes in the plasma metabolome were investigated by applying a comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry metabolomics platform (GC×GC-TOF-MS. Results Plasma insulin response to RB was lower than to WB at 30 min (P = 0.004, 45 min (P = 0.002 and 60 min (P in vitro protein digestibility. There were no differences in GER between breads. From 255 metabolites identified by the metabolomics platform, 26 showed significant postprandial relative changes after 30 minutes of bread intake (p and q values Conclusions A single meal of a low fibre sourdough rye bread producing low postprandial insulin response brings in several changes in plasma amino acids and their metabolites and some of these might have properties beneficial for health.

  5. Evolution of bacterial consortia in spontaneously started rye sourdoughs during two months of daily propagation.

    Full Text Available The evolution of bacterial consortia was studied in six semi-solid rye sourdoughs during long-term backslopping at different temperatures. Each rye sourdough was started spontaneously in a laboratory (dough yield 200, propagated at either 20°C or 30°C, and renewed daily at an inoculation rate of 1∶10 for 56 days. The changes in bacterial diversity over time were followed by both DGGE coupled with partial 16S rRNA gene sequencing and pyrosequencing of bar-coded 16S rRNA gene amplicons. Four species from the genus Lactobacillus (brevis, crustorum, plantarum, and paralimentarius were detected in different combinations in all sourdoughs after 56 propagation cycles. Facultative heterofermentative lactic acid bacteria dominated in sourdoughs fermented at 30°C, while both obligate and facultative heterofermentative LAB were found to dominate in sourdoughs fermented at 20°C. After 56 propagation cycles, Kazachstania unispora (formerly Saccharomyces unisporus was identified as the only yeast species that dominated in sourdoughs fermented at 20°C, while different combinations of strains from four yeast species (Kazachstania unispora, Saccharomyces cerevisiae, Candida krusei and Candida glabrata were detected in sourdoughs propagated at 30°C. The evolution of bacterial communities in sourdoughs fermented at the same temperature did not follow the same time course and changes in the composition of dominant and subdominant bacterial communities occurred even after six weeks of backslopping.

  6. Old regime towns and villages: consent and conflict in local castile

    Directory of Open Access Journals (Sweden)

    Susana Truchuelo García

    2013-12-01

    Full Text Available Castilian towns and villages had a long development process in medieval times. Then, they were formed as political bodies to the prosecution of the common good. Despite town and village reciprocal relationships were part of the common political body they formed together, their relationships were hierarchical. Towns, as heads of jurisdictional districts, kept relations of domination on the villages. There, powerful local lineages tried to widen their authority and power. This traditional scheme, that explained town and village Old Regime relationships, was changing in the long-run perspective. Charles V initiated sales of town titles and privileges to increase royal incomes. This favored not only these last, but also higher degrees of jurisdictional local autonomy and, at the same time, it went in favor of local oligarchies aspirations of wider spheres of local self government

    A digital model was developed to simulate ground-water flow and solute transport for the Upper Floridan aquifer in the Savannah, Georgia-Hilton Head Island, South Carolina, area. The model was used to (1) simulate trends of saltwater intrusion from predevelopment to the present day (1885-2004), (2) project these trends from the present day into the future, and (3) evaluate the relative influence of different assumptions regarding initial and boundary conditions and physical properties. The model is based on a regional, single-density ground-water flow model of coastal Georgia and adjacent parts of South Carolina and Florida. Variable-density ground-water flow and solute transport were simulated using the U.S. Geological Survey finite-element, variable-density solute-transport simulator SUTRA, 1885-2004. The model comprises seven layers: the surficial aquifer system, the Brunswick aquifer system, the Upper Floridan aquifer, the Lower Floridan aquifer, and the intervening confining units. The model was calibrated to September 1998 water levels, for single-density freshwater conditions, then refined using variable density and chloride concentration to give a reasonable match to the trend in the chloride distribution in the Upper Floridan aquifer inferred from field measurements of specific conductance made during 2000, 2002, 2003, and 2004. The model was modified to simulate solute transport by allowing saltwater to enter the system through localized areas near the northern end of Hilton Head Island, at Pinckney Island, and near the Colleton River, and was calibrated to match chloride concentrations inferred from field measurements of specific conductance. This simulation is called the 'Base Case.'

    2009-06-01

    Full Text Available This paper discusses issues in tourism development and visitor management in historic walled towns. Historic towns and walled towns in particular, attract tourists that enjoy the preserved medieval ambience, architecture and picturesque streets. Tourism has an impact on economic and social life as well as on the urban and natural environment. Walled towns and cities with their obvious barriers exemplify and crystallise issues, challenges, and opportunities critical to the development of tourism. A research designed to identify issues related to tourism development and visitor management in walled towns included an extensive questionnaire and two workshops. Eight European historic/ walled towns were included in the research: Chester (United Kingdom, Piran (Slovenia, ’s-Hertogenbosch (Netherlands, Valetta (Malta, Arabarri (Spain, Lucca (Italy, Lörrach (Germany, and Verona (Italy. The questionnaire was used to identify the tourism profile of participating towns as well as the issues and concerns related to tourism development. Participating towns discussed their concerns and exchanged their views and good practices at two workshops. Identified issues include providing adequate tourist information, involvement of residents in tourism development, development of products to decrease seasonality, and concentration of tourism demand. The paper presents good practices and suggests solutions in solving tourism related issues in historic walled towns.

    1. The effects of the dietary inclusion of a Bacillus-based direct-fed microbial (DFM) candidate on digesta viscosity, bacterial translocation, microbiota composition and bone mineralisation were evaluated in broilers consuming rye-based diets. 2. In the present study, control mash rye-based diets (CON) or Bacillus-DFM supplemented diets (TRT) were administered ad libitum to male broilers in three independent experiments. 3. In Experiments 1 and 2 (n = 25/group), liver samples were taken to evaluate bacterial translocation, digesta samples were used for viscosity measurements and the intestinal microbial flora was evaluated from different intestinal sections to enumerate total recovered gram-negative bacteria (TGB), lactic acid bacteria (LAB) and anaerobic bacteria (TAB). Additionally, both tibias were removed for assessment of bone quality. 4. In Experiment 3, each experimental group had 8 replicates of 20 chickens (n = 160/group). Weekly, body weight (BW), feed intake (FI) and feed conversion ratio (FCR) were evaluated. At d 28-of-age, samples were taken to determine bacterial translocation, digesta viscosity and bone quality characteristics. 5. In all experiments, consumption of Bacillus-DFM reduced bacterial translocation to the liver and digesta viscosity. Additionally, DFM supplementation improved BW, bone quality measurements and FCR. Moreover, chickens fed on the Bacillus-DFM diet in Experiments 1 and 2 showed a significant reduction in the number of gram-negative and anaerobic bacteria in the duodenal content compared to control. 6. In summary, chickens fed on a rye-based diet without DFM inclusion showed an increase in bacterial translocation and digesta viscosity, accompanied by reduced performance and bone quality variables relative to the Bacillus-DFM candidate group. Hence, incorporation into the feed of a selected DFM ameliorated the adverse anti-nutritional effects related to utilisation of rye-based diets in broilers chickens.

    Fort McMurray is a booming town, having grown from small town to big city in a short time. A study was conducted to determine how this change affected young people. Results show they felt the changing environment required them to adapt all the time, which was a challenge but also a source of opportunities. Fort McMurray, with a labour shortage, afforded young people a lot of well-paid, flexible part time jobs during high school. These jobs were important to fund their post-secondary education. Although most of the young people saw themselves living elsewhere in 10 years, they could possibly stay if local challenges in the city were addressed.

    The paper discusses the study of atmospheric particulate matter of Bolshoy Kamen town by means of laser granulometry of snow water samples. Snow sampling points were selected close to major enterprises, along the main streets and roads of the town and in the residential area. The near-ground layer of atmospheric air of the town contains particulate matter of three main size classes: under 10 microns, 10-50 microns and over 700 microns. It is shown that the atmosphere of this town is lightly polluted with particles under 10 μm (PM10). Only in 5 sampling points out of 11 we found microparticles potentially hazardous to human health in significant quantities - from 16.2% to 34.6%. On the most territory of the town large particles (over 400 μm) dominate reaching 79.2%. We can conclude that judging by the particle size analysis of snow water samples Bolshoy Kamen town can be considered safe in terms of presence of particles under 10 μm (PM10) in the atmosphere.

  1. A Paradox of Town Spatial Development: The Growing Real Estate and Shrinking Town - a Case Study of Hsinchu County, Taiwan

    2017-04-01

    The key factors of many discussions on shrinking towns are focusing at decreasing population and declining industries. Our study, using Hsinchu County as an example, has found that part of the county (Guanxi township) is following a typical and traditional town development pattern, while somewhere else of this county (Zhubei township) shows rapid growth in real estate but with a high vacancy rate. Even though the distance between Guanxi and Zhubei is less than 20 kilometers, the spatial development phenomenon of the two townships are both "shrinking" in the same county but very different in their developing paths. This study used GIS to overlay the maps from field survey and archive data, such as real estate prices of different years, environmental hazards and disaster records, local area power consumptions, and vulnerable population data, to clarify the causes and systems behind the shrinking phenomena of the two townships and to construct a theory of "shrinking town" in Taiwan. The contribution of this study is the findings of the tangling relations of the vulnerability from land-enclosure policy, the system design of local industrial development and urban planning, and structural factors of environmental hazards. Note: This study is part of the results from the Ministry of Science and Technology funding project (MOST 105-2621-M-120-002) KEYWORDS: shrinking town, environmental hazards, urban planning, spatial disasters, real estate development

    2007-01-01

    The development and implementation of alternative wastewater servicing approaches in rural communities in Australia appears more feasible than in larger urban developments as many rural centres rely on septic tanks and surface discharge of greywater. This method of disposal creates many environmental, social and economic issues and is seen to limit potential for growth in many towns. This paper describes a generic methodology for the selection of innovative sewerage options for six regional towns in Victoria, Australia. The method includes consultation with stakeholders, multi-criteria assessment and concept design of the most favourable option. Despite the broad range of initial wastewater servicing options presented which included cluster-scale systems, upgrade of existing systems, greywater reuse and alternative collection, the outcome for five of the six towns was a modified centralised collection system as the preferred option. Lack of robust and reliable data on the human health risks and environmental impacts of alternative systems were identified as the primary data gaps in the sustainability assessment. In addition, biases in the assessment method due to stakeholder perceptions were found to be an additional issue.

  5. Geophysical Investigations at the Hanna's Town Cemetery, Westmoreland County, Pennsylvania

    Science.gov (United States)

    Taylor, Ashley D.

    Hanna's Town (36WM203), an 18th century site located in Westmoreland County, Pennsylvania, was a major frontier settlement that was attacked and destroyed by a force of British and Native Americans in 1782. The town never fully recovered, and by the early 1800s, no buildings remained from the settlement. The land was repurposed for agricultural use until it was purchased by the Westmoreland County Historical Society, who reconstructed the town for tourism and educational purposes. In addition to the town, the site also contains a cemetery that currently has five headstones. There are several stone fragments in storage that are no longer associated with burials, providing evidence that the cemetery may contain unmarked graves. Geophysical investigations using ground penetrating radar, magnetometry, and electrical resistance were performed to examine the presence of additional grave shafts in and adjacent to the present-day cemetery.

  6. AIR POLLUTION FEATURES OF THE VALLEY-BASED TOWNS IN HUNGARY

    Full Text Available There are 30 valley-based towns with >10,000 inhabitants in Hungary, filled by 1.023 million people i.e. 10 % of the population. Two criteria are used to define the valley-based town. They are: (i Vertical difference between the lowest point in the town and the highest one around it should be >100 m. At the same time, (ii the same difference on the opposite side should be >50 m. Air pollution data by the National Air Pollution Observation Network are used. Five contaminants were selected and analysed for 2007, 2010 and 2013. Due to a sharp reduction in the network, we could find data for a small part of the valley-based towns. Control towns with equal air-quality observations and similar cumulative number of inhabitants were also selected. The contaminants and the number of the settlements are: NO2 manual (14 valley-based vs. 2x14 control, NO2 automatic (8 vs. 8, SO2 automatic (7 vs. 2x6, PM10 automatic (8 vs. 2x7 and PM10 deposition manual (6 vs. 8. Average values, as well as high concentration episodes (>98%thresholds are equally analysed and evaluated. The main conclusion is that there are so big differences between the years both in absolute values and relative sequence of valley-based and control groups that the analysed there years is not enough to make any final conclusion. For step-over frequencies, however valley-based towns have some advantage, possibly due to the valley-hill wind system.

  7. The enduring and spatial nature of the enterprise richness of South African towns

    2017-03-01

    Full Text Available Enterprise richness (measured by the number of enterprise types showed a statistically significant log-log relationship (or power law with the total number of enterprises in (1 towns in different regions of South Africa and (2 towns in the same region but seven decades apart. Entrepreneurial space in towns develops or disappears in a regular way as towns grow or regress, which is further proof of orderliness in the enterprise dynamics of South African towns. The power laws are very similar to one another, which was powerfully illustrated by the fact that one relationship extracted from seven-decade-old information could accurately predict the enterprise richness of modern towns in South Africa. The enterprise richness power law of towns in South Africa extends over space and time. Recent reviews of research on small towns and local economic development in South Africa have ignored the orderliness detected in their enterprise structures. Islands have provided laboratories for the study of natural evolution and the MacArthur-Wilson Species Equilibrium Model based on island biogeography was a main contributor to progress in ecology. Research on regional economic geography in South Africa should move beyond the merely descriptive/narrative to more quantified research. In considering the lack of employment and poverty in South Africa, the National Development Plan suggests that towns and rural areas are important cogs in efforts to overcome these problems. Development plans that are out of sync with the observed regularities are perhaps bound to fail.

    Open joint stock company 'Mashinostroitelny zavod' ('MSZ') is the manufacturer of nuclear fuel for 20 NPPs in Russia, CIS countries and Europe; it is situated in 55 km to the east of Moscow in a town called Electrostal that has the population of 150.000 people. The Public Information Center of the factory established 6 years ago informs the population of and public of the town of the technological and ecological peculiarities of the nuclear fuel production and forms positive attitude towards both, activities of the enterprise and atomic energy on the whole. Annually the Center is visited by up to 1.5 thousand people, mainly these are schoolchildren and college students. This has certain importance. The center maintains constant links with all the educational establishments of the town. Each excursion of the students to the Center turns into an open lesson on the main issues of nuclear physics, energy and ecology.

    Full Text Available Tourists pay for destination brands. This study checked for the relationships between tourists’ profile and how they perceived the destination brand of Cape Town. A questionnaire survey of 220 tourists visiting Cape Town was done. This study found that repeat visit, age of tourist, length of stay, and tourist origin, have significant influences on how tourists visiting Cape Town perceived the destination. The top three destination attributes of Cape Town (cognitive images, which enhance visitor experience satisfaction are (1 the overall level of service quality at facilities in Cape Town, (2 the city being one of the best places the tourists have visited, and (3 the destination’s good value for money. The top three emotional valuations of destination attributes (affective images which enhance visitor experience satisfaction in Cape Town include (1 memorable visit, (2 valuable visit, and (3 friendly and hospitable population. It is therefore recommended that tourism businesses in Cape Town develop relationship marketing tools to attract and retain its tourists segments of loyal, advanced in age, long-staying and domestic tourists. Results from this research could be compared with related findings in the international arena and have related implications, especially for developing economies

    The prevalence of obesity is increasing worldwide and prevention is needed. Whole grain has shown potential to lower the risk of obesity, cardiovascular disease and type 2 diabetes. One possible mechanism behind the benefits of whole grain is the gut fermentation of dietary fiber (DF), e.g. non-starch polysaccharides and resistant starch (RS), in whole grain. The purpose of the study is to investigate the effect of whole grain rye-based products on glucose- and appetite regulation. Twenty-one healthy subjects were provided four rye-based evening test meals in a crossover overnight study design. The test evening meals consisted of either whole grain rye flour bread (RFB) or a 1:1 ratio of whole grain rye flour and rye kernels bread (RFB/RKB), with or without added resistant starch (+RS). White wheat flour bread (WWB) was used as reference evening meal. Blood glucose, insulin, PYY, FFA, IL-6 as well as breath H 2 and subjective rating of appetite were measured the following morning at fasting and repeatedly up to 3.5 h after a standardized breakfast consisting of WWB. Ad libitum energy intake was determined at lunch, 14.5 h after evening test and reference meals, respectively. The evening meal with RFB/RKB + RS decreased postprandial glucose- and insulin responses (iAUC) (P appetite regulation in a semi-acute perspective. Meanwhile, RFB and RFB/RKB improved subjective appetite ratings. The effects probably emanate from gut fermentation events. The study was registered at: ClinicalTrials.gov, register number NCT02347293 ( www.clinicaltrials.gov/ct2/show/NCT02347293 ). Registered 15 January 2015.

    The growth trend of Jakarta city as a Metropolitan city nowadays is the construction of large-scale planned settlement that is often referred to as a new town and is carried out by major developers. The process of land tenure and the process of constructing the new town are directly tangent to the original pre-existing settlements and shape the pattern or types of original settlements in the context of their relationship with the new town. This research was intended to measure the scale of sustainability due to land expansion by new town developers and was measured from the side of the original settlers who still exist. The research method used was descriptive explorative that is by formulating sustainability criteria that match best with research context and using the criteria as a tool to measure the sustainability level of new city development at research site that is new town of Gading Serpong Tangerang. The research concludes that despite the apparent displacement and restriction of original settlement’ lands, it indicates, overall, that new town development meets sustainability criteria when viewed from the residents of three types of the original settlements.

    Full Text Available Abstract Ethiopia is facing rapid urbanization leading to overcrowding and the development of slums and informal settlements with poor waste management practices. Urban dwellers generally consume more resources than rural dwellers and so generate huge quantities of solid wastes. This study is focused on the overall assessment of the existing MSWM service of Gondar town. The overall objective of this study was assessing the current solid waste management service of Gondar town. Both primary and secondary sources were used to achieve the objectives. The analysis of this study was carried out using both qualitative and quantitative techniques. The findings of this study revealed that the present system of MSWM in Gondar town entirely relied on the municipality which provided the full range of waste collection transportation and disposal service. But the provision of this service is not kept in pace with the town solid waste generation. Based on the findings of this study the town households dominantly produced biodegradable solid wastes with generation rate of 0.21kgpersonday. This made the daily total solid waste generation of households to be 8140Kg. Together with other four solid waste sources the total daily solid waste generation of the town is about 11660 kg. So that MSWM of the town is found in very low status and spatial coverage. This poor status of MSWM is also intensified by three critical factors i.e poor institutional structure and capacity of Sanitation and beautification limited participation and contribution of stakeholders and poor households solid waste management practices. This study concluded that there should be sustainable solid waste management systems reuse recycle composting and incineration through awareness creation and training improvement of SB institutional structure and capacity and implementation of integrated MSWM approach which recognizes and comprises all stakeholders in the town.

  20. A STUDY ON LAND SYSTEM INNOVATIONS IN THE CONSTRUCTION OF SMALL TOWNS IN CHINA

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The economic development in China and the rising of the living standard need to speed up the urbanisa-tion. The development of small towns is an important way to Chinese urbanisation. Land use plays a very important rolein the development of small towns. However there are many problems in the development of small towns, esp. in landuse. The paper first discusses the land problems in the development of small towns. Such as much cultivated land liesidle, under-utilization and waste of land, increasing illegal use of land, unstable contractual relationship for land use.The relationship between the development of small towns and land use is also studied. Then the guidelines for the landsystem innovations of small towns are put forward. Namely the sustainability of social and economic development, the bal-ance between land reservation and land utilization, the provision of service to village, agriculture and farmer, the manage-ment of land resource and land assets, the parsimonious and legal use of land. The basic framework of land system innova-tions of small towns is put forward finally. It include the land replacement policy for small towns and the permanent tenan-cy of farmland, the overall plan for land uses and other plans in harmony, the establishment of a flexible system of landsupplies, using land with payments, the transfer of agricultural land and refining the land law related to the constructionof small towns.

  1. Possibilities and limitations of territorial cooperation among Serbian and European towns

    Tošić Branka

    2013-01-01

    Full Text Available This paper deals with the significant European aims of the process of intra-continental integration, as well as the role of the urban centers in its transregional cooperation. Although the process of transborder cooperation of towns exists also in other parts of the world, the roots of that complex form of cooperation appeared rather early in Western Europe. The area of Central Europe, especially the politically unstable southeastern part of the continent, are considerably late in this process. Serbia, especially its western and southern parts, is even more late in transborder regional cooperation of towns. The paper emphasizes that towns of Serbia, as development carriers with their intellectual potentials, have to express the ideas on starting the international actions. The possibilities are extensive: activation of neglected cooperation relations, improvement of technological and economical development, modernization of infrastructural systems, cooperation in culture, education, sports and recreation, environmental protection, etc. Towns need to find the ways for all kinds of cooperation with surrounding towns, if such cooperation gives the results which are favourable for both parties. Isolation from the world courses would lead to long-term stagnation. [Projekat Ministarstva nauke Republike Srbije, br. 176017

    Full Text Available The aim of the present study was to compare the germination of rye brome (Bromus secalinus L. seeds and the initial growth of seedlings under simulated drought and different thermal conditions. The study included two experiments carried out under laboratory conditions in the spring of 2012. The first experiment involved an evaluation of the speed of germination as well as of the biometric characters and weight of seedlings in polyethylene glycol solutions (PEG 8000 in which the water potential was: -0.2; -0.4; -0.65; -0.9 MPa, and in distilled water as the control treatment. The experiment was conducted at the following temperatures: 25/22oC and 18/14oC day/night, at a relative air humidity of 90%. The other experiment, in which lessive soil was used as a germination substrate, was carried out in a plant growth chamber at two levels of air humidity (55–65% and 85–95% and temperature (22/10oC and 16/5oC. The soil moisture content was determined by the gravimetric method and the water potential corresponding to it was as follows: -0.02, -0.07, -0.16, -0.49, -1.55 MPa. The germination capacity and emergence of Bromus secalinus as well as the weight of sprouts produced were significantly dependent on the water potential of the polyethylene glycol solution and on the soil water potential. The emergence of Bromus secalinus was completely inhibited by reducing the soil water potential below -0.16 MPa (the point of strong growth inhibition. The emergence and biometric characters of rye bro- me seedlings were significantly dependent on temperature and air humidity.

    The article deals with the attitude towards the key integration problems of the non Lithuanian population in town Visaginas (its building began in 1975 as Ignalina nuclear power plant - NPP - worker's settlement, first residents settled in 1977, up to 1992 it was named Sniechkus, in 1995 Visaginas received town status). The town was built on Visaginas' lake bank, Ignalina NPP - on Drukshiai lake bank. Ignalina is name of district, one of 44 in Lithuania. Ignalina town is in 14 kilometres from NPP. The situation of language and intercourse was investigated by three stages, three inquests. The first was expert inquest in 1993, the second - workers of Ignalina NPP inquest in 1995, third - inhabitants and institutions of administration of Visaginas and 4 districts around NPP in 1996. Investigation in 1996 displayed the 38% of non-indigenous residents of Visaginas absolutely had no command of Lithuanian (a desire their children to learn the language practically has been expressed by everybody). Inhabitants of Visaginas up to now can't to read any Lithuanian book or newspaper, to listen Lithuanian radio, to see Lithuanian television. The intercourse with indigenous residents mostly are going on Russian because 82% inhabitants of the region around Ignalina NPP can speak in Russian. In Visaginas no one have a good command of English, German or French in time as 2-5% habitants of districts around Visaginas have a good command of the languages. The 14% of non indigenous residents of Visaginas said they had a good command of Lithuanian. Problems of intercourse had 24% inhabitants in Visaginas,.26% - in Ignalina district, 12-13% - in Zarasai, Utena, Shvenchionys (districts around Ignalina NPP). Inhabitants of Visaginas interest for their living land, they have a big tolerance for mixed marriage (indigenous habitants - considerably less). Inhabitants of Visaginas may catch integration in Lithuanian culture in manner from Lithuanian language, and catch wealth which accumulated

  4. The effect of fires on the development and appearance of medieval towns

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available The occurrence of fires was one of the main dangers, which slowed down development of medieval towns. Frequent fires, whether they occurred due to carelessness, poorly maintained fireplaces and chimneys or military attacks, caused damage, particularly to those towns and buildings, which were constructed of inflammable materials such as timber and straw. In medieval times most towns were built using such materials, except those near the coast. Citizens tried to reduce fire hazards and the consequences of fires. With substitution of inflammable materials, apparatus and with the improved maintenance of fireplaces and chimneys, as well as other preventive measures, they influenced the development of towns and thus changed their architectural image.

  6. Coastal ground water at risk - Saltwater contamination at Brunswick, Georgia and Hilton Head Island, South Carolina

    Krause, Richard E.; Clarke, John S.

    2001-01-01

    IntroductionSaltwater contamination is restricting the development of ground-water supply in coastal Georgia and adjacent parts of South Carolina and Florida. The principal source of water in the coastal area is the Upper Floridan aquifer—an extremely permeable and high-yielding aquifer—which was first developed in the late 1800s. Pumping from the aquifer has resulted in substantial ground-water-level decline and subsequent saltwater intrusion of the aquifer from underlying strata containing highly saline water at Brunswick, Georgia, and with encroachment of sea-water into the aquifer at the northern end of Hilton Head Island, South Carolina. The saltwater contamination at these locations has constrained further development of the Upper Floridan aquifer in the coastal area and has created competing demands for the limited supply of freshwater. The Georgia Department of Natural Resources, Georgia Environmental Protection Division (GaEPD) has restricted permitted withdrawal of water from the Upper Floridan aquifer in parts of the coastal area (including the Savannah and Brunswick areas) to 1997 rates, and also has restricted additional permitted pumpage in all 24 coastal area counties to 36 million gallons per day above 1997 rates. These actions have prompted interest in alternative management of the aquifer and in the development of supplemental sources of water supply including those from the shallower surficial and upper and lower Brunswick aquifers and from the deeper Lower Floridan aquifer.

    Benzoxazinoids (BX) are major secondary metabolites of gramineous plants that play an important role in disease resistance and allelopathy. They also have many other unique properties including anti-bacterial and anti-fungal activity, and the ability to reduce alfa-amylase activity. The biosynthesis and modification of BX are controlled by the genes Bx1 ÷ Bx10, GT and glu, and the majority of these Bx genes have been mapped in maize, wheat and rye. However, the genetic basis of BX biosynthesis remains largely uncharacterized apart from some data from maize and wheat. The aim of this study was to isolate, sequence and characterize five genes (ScBx1, ScBx2, ScBx3, ScBx4 and ScBx5) encoding enzymes involved in the synthesis of DIBOA, an important defense compound of rye. Using a modified 3D procedure of BAC library screening, seven BAC clones containing all of the ScBx genes were isolated and sequenced. Bioinformatic analyses of the resulting contigs were used to examine the structure and other features of these genes, including their promoters, introns and 3'UTRs. Comparative analysis showed that the ScBx genes are similar to those of other Poaceae species, especially to the TaBx genes. The polymorphisms present both in the coding sequences and non-coding regions of ScBx in relation to other Bx genes are predicted to have an impact on the expression, structure and properties of the encoded proteins.

    We have isolated a full length cDNA clone encoding the major glycoprotein allergen Lol pI. The clone was selected using a combination of immunological screening of a cDNA expression library and PCR amplification of Lol pI-specific transcripts. Lol pI expressed in bacteria as a fusion protein shows recognition by specific IgE antibodies present in sera of grass pollen-allergic subjects. Northern analysis has shown that the Lol pI transcripts are expressed only in pollen of rye-grass. Molecular cloning of Lol pI provides a molecular genetic approach to study the structure-function relationship of allergens.

    Full Text Available Small town is the gateway of population migrating from rural areas to urban areas in the process of urbanization. The level of its household solid waste treatment is pivotal to the environmental and sanitary quality of surrounding rural areas. Furthermore, small town is the primary administrative center for rural districts, and will impose important influences on the solid waste management in villages. Therefore, it is necessary to investigate the effects of treatment modes on the household solid waste treatment in towns and surrounding villages. Based on the waste generation in small towns, this study analyzed the current status and existing problems for solid waste treatment, and discussed the related administrative management and financial supporting conditions in small towns. By summarizing the characteristics of the existing modes and comparing the costs for different treatment modes, the present study proposed that the most appropriate mode was“diversion in villages-diversion, transportation or treatment in towns-treatment and disposal in counties”, in which the town was the core node for the treatment of rural solid waste, so that the administrative and financial advantages of small towns could be highlighted and consequentially promoted the management of rural solid waste.

    Involvement in car crashes is higher among Israeli Arabs compared to Jews. This study characterized perceived descriptive driving norms (PDDNs) within and outside Arab towns/villages and estimated their association with involvement in car crashes. Arab drivers (594) living in 19 towns and villages were interviewed in face-to-face interviews. The questionnaire included questions about involvement in car crashes, PDDNs within and outside the towns/villages, attitudes toward traffic safety laws, traffic law violations, and socioeconomic and demographic variables. PDDNs represent individuals' perceptions on how safe other people typically drive. The low scores indicate a low percentage of drivers performing unsafe behaviors (safer driving-related norms). A structural equation modeling analysis was applied to identify factors associated with PDDNs and involvement in car crashes. A large difference was found in PDDNs within and outside the towns/villages. Mostly, the respondents reported higher rates of unsafe PDDNs within the towns/villages (mean = 3.76, SD = 0.63) and lower rates of PDDNs outside the towns/villages (mean = 2.12, SD = 0.60). PDDNs outside the towns/villages were associated with involvement in a car crash (r = -0.12, P driving and involvement in car crashes in Arab Israelis. Because PDDNs outside towns/villages were better, increased law enforcement within towns/villages may improve these norms and decrease involvement in car crashes.

  1. Town engineers in South Africa before 1910, with reference to water supply

    Full Text Available This article looks at the town engineers in South Africa prior to Union in 1910. It briefly examines the growth in the number of municipalities and town engineers in the country in this period and investigates the background and training of these engineers; why municipalities decided to appoint an engineer; and what kind of appointment processes were followed. Finally the relations between engineers and town councils and the prevailing circumstances at the end of the engineers’ tenures is studied. The article also presents ten specific cases which have reference to the development of water supply. It emerges that most early town engineers received training via apprenticeship for the positions they held, and that there was added pressure from elected councillors in municipalities who were prone to monitor assiduously how officials were spending public money. It is also clear that engineers who did not have earlier municipal experience were bound to have problems in their interaction with town councillors.

    Cereal products constitute the basis of the diet pyramid. While the consumption of such products as bread decreases, the group of food which popularity increase is cereal snacks. Unfortunately, the dietary value of this group of foodstuffs is limited. Thus, different types of cereal bran may be added to the produced snacks to enhance their nutritive value. However, an addition of bran may have an adverse effect on quality attributes of products. Corn grits enriched with 20 and 40% oat, wheat and rye bran was extruded. Basic parameters determining the nutritive value, physical characteristics and sensory attributes of the six produced types of extrudates were measured and compared. Moreover, the effect of additives applied on viscosity of aqueous suspensions of the raw materials and extrudates under controlled conditions was measured using RVA. The dietary value of snacks containing bran depends on the type and quantitative shares of the additives. The content of dietary fibre in produced extrudates ranged from 6.5 to 15.8%, including soluble dietary fibre at 2.1 to 3.7%. With an increase of bran content in extrudates, their expansion decreased, density increased and the colour of extrudates changed (reduced brightness, increased a*, decreased b*). In sensory evaluation the highest acceptability was given to extrudates with a 20% addition of oat bran, while the lowest was given for those with 40% wheat bran. Based on PCA results positive correlations were found between overall desirability and crispiness, porosity, taste, colour and expansion. Negative correlations between desirability and hardness and density of extrudates were observed. The additives and their level also had an effect on changes in viscosity of aqueous suspensions measured using RVA. However, no correlation was found between quality features of extrudates and values of attributes measured in the analysis of viscosity. In the production of corn extruded snacks an addition of oat, wheat and rye bran

    Background: Whole-grain intake is associated with a lower risk of chronic Western-style diseases, possibly brought about by the high concentration of phytochemicals, among them plant lignans (PLs), in the grains. Objective: We studied whether treatment of rye bran with cell wall-degrading enzymes changed the solubility and kinetics of PLs in multicatheterized pigs. Methods: Ten female Duroc × Danish Landrace × Yorkshire pigs (60.3 ± 2.3 kg at surgery) fitted with permanent catheters were included in an incomplete crossover study. The pigs were fed 2 experimental diets for 1-7 d. The diets were rich in PLs and based on nontreated lignan-rich [LR; lignan concentration: 20.2 mg dry matter (DM)/kg] or enzymatically treated lignan-rich (ENZLR; lignan concentration: 27.8 mg DM/kg) rye bran. Plasma concentrations of PLs and enterolignans were quantified with the use of targeted LC-tandem mass spectrometry. Data were log transformed and analyzed with mixed-effects, 1-compartment, and asymptotic regression models. Results: The availability of PLs was 38% greater in ENZLR than in LR, and the soluble fraction of PLs was 49% in ENZLR compared with 35% in LR diets. PLs appeared in the circulation 30 min after intake of both the ENZLR and LR diets. Postprandially, consumption of ENZLR resulted in a 4-times-greater ( P concentration compared with LR. The area under the curve (AUC) measured 0-360 min after ENZLR intake was ∼2 times higher than after LR intake. A 1-compartment model could describe the postprandial increase in plasma concentration after ENZLR intake, whereas an asymptotic regression model described the plasma concentrations after LR intake. Despite increased available and soluble PLs, ENZLR did not increase plasma enterolignans. Conclusion: The modification of rye bran with cell wall-degrading enzymes resulted in significantly greater plasma concentrations of PLs and the 4-h AUC, particularly syringaresinol, in multicatheterized pigs. © 2017 American Society

    Full Text Available Transition Towns is a citizen-led movement that seeks to address individual and societal dependence on fossil fuels and the need to reduce greenhouse gas production in order to fight climate change. The foundation of Transition is permaculture, a design process based on whole-systems thinking informed by the patterns and relationships found in nature. Since its inception in 2005, the Transition movement has spread worldwide, as people in small groups and across large towns look for ways to take practical action to fight climate change: from home vegetable gardens to weatherization work parties, from time banks and tool shares to renewable energy systems. Transition looks different in every location because it meets the needs and draws on the skills of the local community. This article looks at Transition in one community: The Twin Cities of Minneapolis and St. Paul, profiling several Transition Town groups.

  11. Immunochemical studies of Lolium perenne (rye grass) pollen allergens, Lol p I, II, and III.

    Science.gov (United States)

    Ansari, A A; Kihara, T K; Marsh, D G

    1987-12-15

    It was reported earlier that human immune responses to three perennial rye grass (Lolium perenne) pollen allergens, Lol p I, II, and III, are associated with histocompatibility leukocyte antigen (HLA)-DR3. Rye-allergic people are often concordantly sensitive to all three of these allergens. Since earlier studies suggested that these antigens are non-cross-reactive, their immunologic relatedness by double antibody radioimmunoassay (DARIA) was studied in order to understand further the immunochemical basis for the concordant recognition of the three allergens. Direct binding DARIA studies were performed with human sera from 189 allergic subjects. Inhibition DARIA studies were carried out with 17 human sera from grass-allergic patients who were on grass immunotherapy, one goat anti-serum, and six rabbit antisera. None of the sera detected any significant degree of two-way cross-reactivity between Lol p I and II, or between Lol p I and III. However, the degree of two-way cross-reactivity between Lol p II and III exhibited by individual human and animal antisera varied between undetectable and 100%. In general, the degree of cross-reactivity between Lol p II and III was higher among human sera than among animal sera. Taken together with earlier findings that antibody responses to Lol p I, II and III are associated with HLA-HDR3, and that most Lol p II and III responders are also Lol p I responders, but not vice versa, our present results suggest the following: the HLA-DR3-encoded Ia molecule recognizes a similar immunodominant Ia recognition site (agretope) shared between Lol p I and Lol p II and/or III; in addition, Lol p I appears to contain unique Ia recognition site(s) not present in Lol p II and III. However, further epitope analyses are required to investigate these possibilities.

    Full Text Available Through field research of typical villages and towns in China's northern cold region, this paper research energy consumption and resource recovery in the process of village and town garbage collection and disposal and organizes current situation and problems of village and town garbage collection and disposal. At present, village and town garbage collection and disposal means and thoughts are traditional and lag behind in China's northern cold region. There is the lack of garbage collection and disposal mode suitable for cold villages and towns. Thus, village and town resources are not effectively utilized, and residents’ living environment is affected continuously. This paper selects two mature garbage disposal methods: sanitary landfill and incineration power generation. Meanwhile, energy consumption and ultimate emission utilization of two schemes in garbage collection and disposal links are overall compared to propose garbage collection and disposal mode with low energy consumption suitable for green villages and towns in cold region. Besides, various control indexes of village and town garbage disposal schemes are explained in detail in combination of specific conditions.

    In Malaysia small towns are an important source of population gowth in metropolitan areas. To provide empirical evidence of the magnitude and roles of small urban centers as complementary sources of population growth in metropolitan areas, a small survey was conducted in 10 small towns in the State of Selangor. Criteria for the selection of these towns include a fair geographical spread over the State, and each area must characteristically possess a dominant urban center. The questionnaires were directed to the heads of 300 households with the intention of investigating the socioeconomic background of the households and the magnitude and characteristics of those members of the households who have migrated elsewhere. The total number of outmigrants from each area varied from 27-57, giving an overall average figure of 1.53 outmigrants/household. About 77% of the outmigrants had moved to the metropolitan centers. As the majority of the metropolitan migrants were more attracted to Kuala Lumpur, Klang, and Petaling Jaya, it may be assumed that the total outmigrants from small towns as derived would have consitituted about 39% of the population in the Klang Valley region. Based on this estimate, the role of small towns in metropolitan population growth is important. In the survey conducted, 2 broad categories of movements were involved: "economic movers," i.e., those who migrated to work or to establish businesses in the metropolitan areas; and "noneconomic movers," i.e., those who moved to continue their studies or to follow their spouses, and so forth. The economic mover stream made up 71% of the total metropolitan migrants. 2 variables--marital status and sex--were significantly related to the economic or noneconomic nature of the metropolitan migrants. The movement of males tended to be associated with economic motives whereas noneconomic reasons for movement tended to be the case among females migrants. The most important occupational group of the economically

    2009-04-01

    We present the results of magnetic and geoelectrical surveys carried out in a Roman age town Porolissum (NW Romania). Porolissum was the capital of the province Dacia Porolissensis in the 2nd and 3rd centuries, and it had 20000 inhabitants. After the Romans left Dacia the town was deserted. The buildings in the town were built from dacite mined in nearby quarries. The dacite has large magnetic susceptibility and large electric resistivity compared to the soil, which allows the detection of the ruins by magnetic and geoelectrical measurements. We made magnetic surveying using GSM-19 Overhauser magnetometers in the fortress, the town and the cemetery. We were able to map streets, foundations of different buildings: houses, sanctuaries, and in the cemetery roads, graves and graveyards. In those places where the interpretation of the results of the magnetic surveys was not clear, geoelectrical measurements were made to clarify the presence of dacite. The geophysical surveys help to reconstruct the structure of the archeological objects, and on large scale the structure of the town. Based upon our results, the archeologists dug more trenches, which confirmed the interpretation of geophysical measurements.

    Full Text Available Street art comprises all kinds of art developed in public locations. This form of art has spread to all heritage streets in George Town, the capital of Penang Island, which is also a known UNESCO World Heritage Site. However, instead of its heritage, food, and interesting past life and structure, the rapid multiplication of street art in George Town has created a new and unusual art that attracts tourists. Street art has spread to small roads and heritage streets in the city. This art increases the awareness of spectators by introducing them to the rich history of these streets and inducing a lively concept in the inner city of George Town. Accordingly, the impact of iron rod sculptures and murals, which comprises approximately 90% of street art in George Town, were determined to explore and identify the effects of this street art on this world heritage site. The findings were obtained from 263 out of 306 questionnaires accomplished by tourists in George Town. The results confirm that tourists prefer murals over iron rod sculptures. Iron rod sculptures are designed to tell the history of the street, whereas murals are designed to create aesthetic value. The findings indicated that similar to iron rod sculptures, more control should be exercised on the subjects of murals.

    The roots of hospital foundation in Serbs date from the 12th century, when the hospitals in the monasteries Hilandar (1199) and Studenica (1207) were established. The "Town" Hospital of Belgrade was founded in 1841, which had the status of town and regional hospital until 1881. After that, it was transformed into a general state-owned hospital based on the Law of National Health Protection. The inhabitants of Belgrade obtained a municipal hospital again in 1935, when the "City" Hospital was founded in Zvezdara municipality, named at that period Bulbulder. By researching and observing hospital diet development of municipal hospitals in Belgrade, it was concluded that from the very beginning of the "Town" Hospital functioning there was awareness about its significance, place and role in the overall treatment of patients. Hospital diet, regardless of existing knowledge as the part of medical doctrines of particular time-periods, was often conditioned by limited hospital budgets and under the influence of different social movements and wartime periods

    Barnes, J P; Putnam, A R

    1987-04-01

    Two phytotoxic compounds [2,4-dihydroxy-1,4(2H)-benzoxazin-3-one (DIBOA) and 2(3H)-benzoxazolinone (BOA)] were previously isolated and identified in 35-day-old greenhouse-grown rye shoot tissue. Both compounds were also detected by TLC in greenhouse-grown root and fieldgrown shoot tissue. The concentration of DIBOA varied in the tissues, with the greatest quantity detected in greenhouse-grown shoots. DIBOA and BOA were compared with β-phenyllactic acid (PLA) and β-hydroxybutyric acid (HBA) for activity on seed germination and seedling growth and were consistently more toxic than either compound. Dicot species tested, including lettuce (Lactuca sativa L.), tomato (Lycopersicon esculentum Mill.), and redroot pigweed (Amaranthus retroflexus L.), were 30% more sensitive than the monocots tested. Of the two benzoxazinone compounds, DIBOA was most toxic to seedling growth. DIBOA and BOA reduced chlorophyll production inChlamydomonas rheinhardtii Dangeard, by 50% at 7.5 × 10(-5) M and 1.0 × 10(-3) M, respectively. Both DIBOA and BOA inhibited emergence of barnyardgrass (Echinochloa crusgalli L. Beauv.), cress (Lepidium sativum L.), and lettuce when applied to soil, indicating their potential for allelopathic activity.

    Grass pollen, especially of rye-grass (Lolium perenne). represents an important cause of type I allergy. Identification of IgE-binding (allergenic) epitopes of major grass pollen allergens is essential for understanding the molecular basis of interaction between allergens and human IgE antibodies and therefore facilitates the devising of safer and more effective diagnostic and immunotherapy reagents. The aim of this study was to identify the allergenic epitopes of Lol p 5, a major allergen of rye-grass pollen, immunodissect these epitopes further so that the amino acid residues critical for antibody binding can be determined and investigate the conservation and nature of these epitopes within the context of the natural grass pollen allergens. Peptides, 12-13 amino acid residues long and overlapping each other by 4 amino acid residues, based on the entire deduced amino acid sequence of the coding region of Lol p 5, were synthesised and assayed for IgE-binding. Two strong IgE-binding epitopes (Lol p 5 (49-60) and (265-276), referred to as peptides 7 and 34, respectively) were identified. These epitopes were further resolved by truncated peptides and amino acid replacement studies and the amino acid residues critical for IgE-binding determined (Lol p 5 (49-60) residue Lys57 and (265-276) residue Lys275). Sequences of these epitopes were conserved in related allergens and may form the conserved allergenic domains responsible for the cross-reactivity observed between pollen allergens of taxonomically related grasses. Furthermore, due to its strong IgE-reactivity, synthetic peptide Lol p 5 (265-276) was used to affinity-purify specific IgE antibodies which recognised proteins of other clinically important grass pollens. further indicating presence of allergenic cross-reactivity at the level of allergenic epitope. Moreover, Lol p 5 (265 276) demonstrated a strong capacity to inhibit IgE-binding to natural rye-grass pollen proteins highlighting the antibody accessibility

    Full Text Available This study deals with the early history of Jimma town and its growth from its foundation until 1936. It explores social, economic and administrative themes, but also attempts to show the interrelationship between these themes. The town of Jimma evolved during this period from being the home-town of a relatively homogenous society and culture into a place of residence for a diverse and increasingly cosmopolitan population. Economically, the story of Jimma during this period is one of both continuity and change. It is a story of continuity because Jimma, which had been a center of trade from the very beginning, continued to be so during this period. There was significant change, however, because unlike the previous decades in which Jimma had served as a point of exchange or transit for elite goods that mostly originated from beyond the borders of the Oromo Kingdom (such as slaves, ivory and musk, during this period the town developed into the chief center for the collection, organization and export of a cash crop that was grown locally (coffee.

  4. Do transition towns have the potential to promote health and well-being? A health impact assessment of a transition town initiative.

    Climate change and energy vulnerability present significant challenges for the development and sustainability of our communities. The adverse effects will most likely impact on those already experiencing poverty, as energy and food costs will rise, thus increasing inequalities in health. Transition town initiatives seek to build cohesive sustainable communities to prepare for a future with limited oil and a changing climate. Increasingly, public health practitioners are interested in the role of transition towns as a community development initiative, and their potential to support the wider public health agenda. Health impact assessment (HIA) is an evidence-based process that aims to predict the positive and negative impacts of a strategy, proposal or development. The HIA process provides an opportunity to promote sustainable communities by ensuring that new strategies and developments are considered in the context of their contribution to the health and well-being of local populations. The aim of this study was to use an HIA to examine the potential health and well-being benefits of two related transition town initiatives. A rapid HIA to consider the potential lifestyle changes and health and well-being impacts of Transition Together/Transition Streets (TT/TS) projects. An HIA template was used to assess key documents related to the TT/TS initiatives and those related to the characteristics of the community. Additionally, meetings with 12 key informants (four involved in TT/TS and eight purposively selected for their local knowledge) were held using the HIA template to focus the discussion. The findings highlight the associated lifestyle changes such as increased physical activity and healthy eating, and possible social and well-being benefits of engagement in such an initiative. Engagement may be limited to those already concerned about environmental issues. This paper illustrates the important links between transition towns and the wider public health agenda

    The arrival of the British colony in Kuala Lumpur sparked a radical change in the town in terms of infrastructure and town planning. Due to the British Empire’s reign over Malaya in the advent of 20th century, the colonial architectural style has influenced a lot of important building in the royal town of Selangor. Some of the building is abandoned disrespect, disregard and it’s frightening. Many deemed historic buildings and structures disappears in exchange for modernity, which is a threat to the townscape and history. The local council of Klang aims to preserve clusters of colonial sights, place of worships, schools, and remnants of a fort that has shaped the town enabling people to be more appreciative towards it. Located in the heart of Klang town, the fire station sits next to another heritage trail icon, Raja Abdullah Warehouse. Without proper documentation and curation, the building significant will remain unknown and eventually disappear. The core of this paper will showcase the building design quality and its importance, as the first attempt to document the Balai Bomba Klang Selatan to assist in conserving its tangible and intangible qualities. The study aims to collate and document the tangible qualities of the fire station to complement the measured drawing exercise.

    For promoting the introduction of new energy and for enhancing people's consciousness of such at Itakura Town, Niigata Prefecture, surveys and studies were conducted involving energy demand of the town, the amount of new energy resources in existence, and new energy introduction projects, and a vision was formulated. In fiscal 2000 the town consumed 549,973 GJ/year in energy, with the industrial sector consuming 202,014 GJ, the residential/commercial sector 194,233 GJ, and the transportation sector 153,725 GJ. The energy types were gasoline, kerosene, electricity, gas oil, heavy oil, and LPG, as named in the descending order in terms of consumed amount. It is estimated that the energy consumption resulted in the emission of carbon dioxide of 11,839 t-C/year. New energy introduction projects were discussed, which involved wind power generation for the Itakura sewage purification center; snow-aided cooling systems for a Yasuragi rest house and the special nursing home for elderly people; snow-aided refrigeration for a unhusked rice silo; photovoltaic power generation and cogeneration for the town office; photovoltaic/wind power-driven hybrid street lamps; use of biomass solid fuel for heating public facilities; use of clean-energy vehicles as official vehicles; and the like.

    In Stone Town, Zanzibar, sewage treatment is minimal, with a biological oxygen demand reduction to 60% and no removal of bacteria or nutrients. Here, Stone Town’s sewage pollution was studied by measuring Enterococci and NH 4 + concentrations in seawater and δ 15 N of benthic organisms; samples were collected along the Stone Town shoreline and from offshore coral reefs. Public perceptions of sewage pollution were investigated via interviews. Enterococci from the Stone Town shoreline exceeded USEPA guidelines for recreational use. Benthic organisms from two of the four reefs were relatively enriched (δ 15 N > 10‰), indicative of sewage derived N. δ 15 N values of organisms from Stone Town exceeded 16‰. A strong correlation was found between Enterococci and δ 15 N across sites, while step-wise regression indicated rainfall and tidal stage as important predictors for bacterial concentrations. These data provide an important impact assessment from which the efficacy of future policy and management change can be assessed.

    To identify the behavioral mechanisms and effects of tobacco control policies designed to reduce tobacco retailer density. We developed the Tobacco Town agent-based simulation model to examine 4 types of retailer reduction policies: (1) random retailer reduction, (2) restriction by type of retailer, (3) limiting proximity of retailers to schools, and (4) limiting proximity of retailers to each other. The model examined the effects of these policies alone and in combination across 4 different types of towns, defined by 2 levels of population density (urban vs suburban) and 2 levels of income (higher vs lower). Model results indicated that reduction of retailer density has the potential to decrease accessibility of tobacco products by driving up search and purchase costs. Policy effects varied by town type: proximity policies worked better in dense, urban towns whereas retailer type and random retailer reduction worked better in less-dense, suburban settings. Comprehensive retailer density reduction policies have excellent potential to reduce the public health burden of tobacco use in communities.

    66,000 children and adolescents are treated at emergency departments (EDs) in England and Wales each year for assault injury. The aim of this study was to compare adolescent assault injury rates in cities and towns and determine how assault injury varies with deprivation and gender. The study was set in three cities in Wales, UK, and their surrounding towns. Subjects were 11-17 year olds treated for assault injury at one of seven EDs from 1 October 2005 to 30 September 2006. Area of residence (electoral divisions, EDivs) was identified from patient postcode. EDivs were aggregated into deprivation fifths for males and females and cities and towns. Assault injury rates, rate ratios and 95% CIs were calculated. 1472 children and adolescents of 11-17 years old were treated for assault injury. Male city assault injury rates were 14.2/1000 11-17 year olds; and 13.1 in towns. Female city assault injury rates were 6.0; and 5.6 in towns. In the most deprived city areas males had assault injury rates 2.6 times (95% CI 1.85 to 3.59) that of the most affluent, compared with 2.0 times in towns (95% CI 1.39 to 2.86). For females, the most deprived city areas had assault injury rates 5.3 times that of the most affluent (95% CI 2.93 to 9.41), compared with 2.8 times in towns (95% CI 1.47 to 5.28). Injury in youth violence increased with increasing deprivation in cities and their feeder towns. This was true for boys and girls, though rates for boys were consistently higher. This link between assault injury and deprivation was stronger for girls in cities than in feeder towns. Strategies to prevent youth violence need to include improved safeguarding arrangements for girls living in the most deprived city areas.

  14. Model training across multiple breeding cycles significantly improves genomic prediction accuracy in rye (Secale cereale L.).

    Genomic prediction accuracy can be significantly increased by model calibration across multiple breeding cycles as long as selection cycles are connected by common ancestors. In hybrid rye breeding, application of genome-based prediction is expected to increase selection gain because of long selection cycles in population improvement and development of hybrid components. Essentially two prediction scenarios arise: (1) prediction of the genetic value of lines from the same breeding cycle in which model training is performed and (2) prediction of lines from subsequent cycles. It is the latter from which a reduction in cycle length and consequently the strongest impact on selection gain is expected. We empirically investigated genome-based prediction of grain yield, plant height and thousand kernel weight within and across four selection cycles of a hybrid rye breeding program. Prediction performance was assessed using genomic and pedigree-based best linear unbiased prediction (GBLUP and PBLUP). A total of 1040 S 2 lines were genotyped with 16 k SNPs and each year testcrosses of 260 S 2 lines were phenotyped in seven or eight locations. The performance gap between GBLUP and PBLUP increased significantly for all traits when model calibration was performed on aggregated data from several cycles. Prediction accuracies obtained from cross-validation were in the order of 0.70 for all traits when data from all cycles (N CS  = 832) were used for model training and exceeded within-cycle accuracies in all cases. As long as selection cycles are connected by a sufficient number of common ancestors and prediction accuracy has not reached a plateau when increasing sample size, aggregating data from several preceding cycles is recommended for predicting genetic values in subsequent cycles despite decreasing relatedness over time.

    2015-01-01

    This paper analyzes the generation and composition of municipal solid waste in Spanish towns and cities with more than 5000 inhabitants, which altogether account for 87% of the Spanish population. To do so, the total composition and generation of municipal solid waste fractions were obtained from 135 towns and cities. Homogeneity tests revealed heterogeneity in the proportions of municipal solid waste fractions from one city to another. Statistical analyses identified significant differences in the generation of glass in cities of different sizes and in the generation of all fractions depending on the hydrographic area. Finally, linear regression models and residuals analysis were applied to analyze the effect of different demographic, geographic, and socioeconomic variables on the generation of waste fractions. The conclusions show that more densely populated towns, a hydrographic area, and cities with over 50,000 inhabitants have higher waste generation rates, while certain socioeconomic variables (people/car) decrease that generation. Other socioeconomic variables (foreigners and unemployment) show a positive and null influence on that waste generation, respectively.

    Irradiated with 60 Co γ-rays (12 Gy), the pollen of wheat landrace Huixianhong-Secale cereal cv. Jingzhouheimai DA1R was pollinated to the emasculated spikes of Huixianhong. Analyzed with genomic in situ hybridization GISH using gDNA of rye cv. Jingzhouheimai as a probe, four plants with reciprocal translocation, four plants with large segmental translocation and one plant with distal segmental translocation, one plant with one telocentric chromosome were identified from 33 M 1 seeds. The results showed that the translocation frequency was 30.30% and of the total 11 breakage-fusion events, 1 involved centric regions and 10 involved interstitial regions. The experiment showed that pollen irradiation was an effective method to induce wheat alien chromosomal structural variations which could effectively by used in deletion mapping, chromosomal location of important agronomic genes and development of small segmental translocations with target genes.

    Rye contains high concentrations of non-starch polysaccharides (NSPs), leading to reduced digestibility. Since poultry have little or no endogenous enzymes capable of hydrolyzing these NSP, exogenous carbohydrases as feed additives are used in an attempt to reduce the anti-nutritional effects of these polysaccharides. Previously, an in vitro study conducted in our laboratory showed that inclusion of certain Bacillus direct-fed microbial (DFM) candidates that produce exogenous phytase, lipase, protease, cellulase, and xylanase in high-NSP diets significantly reduced both digesta viscosity and Clostridium perfringens proliferation. In the present study, rye-based turkey starter diets with or without Bacillus-DFM were administered ad libitum to day-of-hatch turkey poults in two independent experiments. In both experiments, day-of-hatch turkey poults were randomly assigned to either a control diet (CON) or a DFM treated diet (n = 25 birds/group). At 10 days-of-age, all turkey poults from experiments 1 and 2 were weighted and 12 turkey poults/group were randomly selected and humanely killed. Liver samples were aseptically collected to evaluate bacterial translocation, and intestinal digesta samples were individually collected to evaluate viscosity. Additionally, in experiment 2 both tibias were removed for assessment of bone parameters. In both experiments, the treated group showed a reduction in the total number of coliforms in the liver and a reduced digesta viscosity when compared to the CON group (P content, calcium content, and phosphorus content when compared with CON turkey poults. In summary, turkey poults fed with a rye-based diet without DFM showed an increase in bacterial translocation and digesta viscosity, accompanied by a reduction in bone mineralization; however, these adverse effects can be prevented by the inclusion of selected a Bacillus-DFM candidate in high-NSP diets.

    2014-10-01

    Full Text Available The paper describes the transformation of derelict land into a 'town-green' and the role legislation played in transforming social and natural relationships. Town-green denotes a legal status under the Great Britain Commons Act (2006 that protects certain open spaces from building development; the status requires that a space must simultaneously have a specific social quality (i.e. 'town-ness' and a specific natural quality (i.e. 'green-ness'. This hybrid condition requires an alliance between society and nature in a certain configuration (referred to here as nature2 and society2. In this empirical study it involved the participation and consensus of local residents, volunteer gardeners as well as nature itself; flowers needed to bloom and grass had to grow in order for the hybrid town-green status to be conferred. There are two distinct phases of this transformation; the first is the change in identities and configuration of the constituents of town and green. This involved the production of a modified 'real' world with: different plants and flowers; reconfigured spatial arrangements; as well as different social actors. The second phase is a shift from changes in the "real" world towards an 'enmap' - a displacement of myriad actors into documentation. This transfer from a complex messy reality into an enmap permitted the legitimation of the new network to be accepted as a 'town-green'. What the research reveals, other than hints for gardeners and community activists, is how material and non-material; social and natural; spatial, discursive and temporal worlds are hybridised.

    Land sliding in the area of the town of Ocna Mures Situated near the center of Romania, the town of Ocna Mures, Alba county, once was considered a health resort. Positioned on the left bank of the river Mures, it has a most important natural asset - that is salt. This town began its growth around the year 1896 when the Sodium Product Plant came into being. From the salt extracted as brine they obtained different chlorine-sodium products. On the morning of December 22, 2010, a landslide occurred in the area close to the center of the town, causing a release of a great deal of salty water that soon formed a lake. During that day the big supermarket that was situated on the back of the sliding area collapsed into the crater of the newly formed salty lake. Due to this sliding the main road began to present huge cracks and it sank into the ground around 3 meters, along a length of 100 meters. Thus the asphalt wrinkled as a result of the landslide and one can no longer use the road. Together with my students I went to that area in order to study the alterations that were produced in the ground and to observe the efforts of the specialized workers trying to avoid a catastrophe. Thus we learned that a variety of corrections were needed: - The design and the installation of a barrier around that area in order to prevent more plain water to enter; - Stopping excavations of pebbles from the river Mures over an area of 5 kilometers up- and down-river of the town area; - The removal of the other salty lakes from the town area; - The new design of the sewer system of the town using resistant materials; - Increased capacity of the sewer system for industrial water and drainage from the abundant rains; - The planting of trees in the area in order to fix the ground and prevent new landslides; In order to establish the safety coefficient to protect the salt reserve due to its ubiquity they have to consult seismology specialists. Therefore they have to do all the necessary efforts in

    1981-05-01

    Full Text Available The effect of a synthetic chelating compound on the dry matter yield and the uptake of soil P, Al, Fe, Mn, Mg and Ca by Italian rye grass was studied in a pot experiment with three mineral soil samples irrigated with water or 0.001 M Na2-EDTA(dinatrium salt of ethylenediaminetetraacetic acid solution. The Na2-EDTA treatment seemed not to affect the quantity of the dry matter yields, but it affected markedly their chemical composition. Increased contents of P, Al and Fe were found in all the harvests. In two soil samples the P supply was improved by 35—45 %. The accumulation of Al, Fe and Mn induced by Na2-EDTA tended to be the more effective the greater the stability constant for the corresponding metal-EDTA chelate was. Thus, the iron uptake increased most intensively, i.e. by 217—458 %, and that of aluminium by 33—120 %. On the basis of the first two harvests the manganese absorption by the rye grass seemed to decrease probably due to the enormous accumulation of iron. The results also suggested that the addition of Na2-EDTA to the soil was not able essentially to affect the magnesium and calcium supply to the plants.

    Full Text Available The Satellite town of Korangiis part of the ‘Greater Karachi Resettlement Plan’ along with other satellite towns of Landhi and New Karachi proposed by the Greek Architect Constantinos Apostolou Doxiadis in 1958. It is located in southern part of Karachi next to the Arabian Sea at latitude: 24°49' and longitude: 67° 7'. It is considered as one of the major post-independence urban regeneration projects. The actual plan of Doxiadis was supposed to be developed as self-sufficient satellite town for refugees (from Indian sub-continent partition with the provision of employment through industries and commercial areas along with residential settlement. This research revolves around the planning strategies adopted by the architect influenced by the indigenous way of living. The analysis is based upon the main proposition of the Greater Karachi Resettlement Plan that aimed to develop industrial activity in the satellite towns of Landhi-Korangi and North Karachi freeing the central Karachi from low income groups (poor and from environmental degradation. From here began the multiple issues mainly the transportation troubles of city, as these settlement towns were positioned at least 25 Kilometer off the city centre which probably was the only working hub for most of people then. This eventually led to the failure of the plan leaving behind the inhabitants with economic pandemonium. The objective of this research is to understand the issues related to the existing satellite town and the reasons for its decline; not growing on the pace of what it was assumed to develop. The paper also focuses on the stated argument of the failure of this massive relocation plan and its impacts on rest of the city.

  12. Influence of small towns on the lichen vegetation. Part VII. Discussion and general conclusions

    Energy Technology Data Exchange (ETDEWEB)

    Rydzak, J

    1958-01-01

    The problem of poverty of lichen vegetation in large or industrial towns was raised in 1866. Since then several large European cities have been studied and there were described zones of gradual impoverishment of lichen flora from the outskirts to the centre of the town. The zones are: (1) Zone of normally developed flora at the outskirts of the town. (2) Struggle zone which is a more or less extensive area with scattered houses and which surrounds the crowded central quarters. In this zone scanty specimens of a few lichen species were found; their thalli were contracted, under-developed, as if fighting for life in unfavorable environmental conditions. (3) Lichen-free zone, lichen desert, which comprises the centre of the town and its industrial quarters; no lichens could be found there. The results of these investigations strengthened the belief that lichens are organisms very sensitive to the action of substances formed during coal combustion in town. Sulphur dioxide (SO/sub 2/) was believed to be especially harmful to lichens, causing their death even in trace concentrations.

    1994-07-01

    This report presents the methods used and the results obtained from an investigation of relationships between energy use for transport and the physical urban structure of 22 towns in Denmark, Iceland, Norway and Sweden. It is found that urban planning is very important for the inhabitants' average energy use for transport. High population density in the inner and central areas of a town tends to reduce the energy use. The composition of trades and the commuting frequency between the town and its surroundings affect the energy use to the same degree as does the urban planning. The energy data are based on the oil companies' information on the sales of gasoline and auto diesel oil from the filling stations in each town and on the public transport companies' information on the energy use of their vehicles. The energy data are combined with physical and socio economical characteristics of each town.

    2013-01-01

    To compare perceptions about rural road and general driving behaviors between teens who live in- and out-of-town from rural communities in Iowa. A cross-sectional survey was conducted with 160 teens anticipating their Intermediate License within 3 months upon enrollment into this study. Self-administered surveys were used to collect demographics and driving exposures (eg, frequency of driving, age when first drove unsupervised). Two Likert scales were included to measure agreement with safe driving behaviors on rural roads and general safe driving behaviors (eg, speeding, seat belt use). T-tests were calculated comparing mean composite scores between in- and out-of-town teens, and between mean rural road and general driving safety attitude scores. A linear regression multivariable model was constructed to identify predictors of the rural road score. While the majority of teens endorsed rural road and general safe driving behaviors, up to 40% did not. Thirty-two percent did not believe the dangers of animals on rural roads, and 40% disagreed that exceeding the speed limit is dangerous. In-town teens were less safety conscious about rural road hazards with a significantly lower mean composite score (4.4) than out-of-town teens (4.6); mean scores for general driving behaviors were similar. Living out-of-town and owning one's own car were significant predictors of increased rural road safety scores. Rural, in-town teens have poorer safety attitudes about rural roadway hazards compared with out-of-town teens. Interventions that involve education, parental supervision, and practice on rural roads are critical for preventing teen crashes on rural roads. No claim to original US government works.

    Hyldgård, Carl-Erik; Brohus, Henrik

    In connection with the research programme "Healthy Buildings", a building with indoor air quality problems was selected for further investigations. A Danish town hall was chosen because of many complaints over several years. A full-scale mock-up of a typical town hall office was built...... in the climate laboratory. A new heating and ventilating system and a new control strategy were chosen and implemented into the town hall. It was found that air supply upwards along a window may make it nearly impossible to achieve comfort and a good air quality the year round without full-scale measurements....

    Full Text Available With the help of mathematical modeling of atmospheric transport the calculations of accidental release dispersion from the Chernobyl NPP to town Pripjat during period from 26 till 29 April 1986 have been carried out. Data of gamma rate measurements which was made in 31 points of the town were used. Based on the solution of atmospheric transport inverse problem the reconstruction of Chernobyl source parameters has been made including release intensity and effective source height. The input of main dose-forming radionuclides into the exposure dose during the first 40 hours after the accident (the period of population residence in the town before the evacuation has been estimated. According to the calculations the 131I deposition density averaged over the town territory was about 5.2 × 104 kBq/m2 (on 29.04.86. Minimum and maximum 131I deposition values were 2.8 × 104 kBq/m2 (western part, distance to the unit is 4.5 km and 1.2 × 105 kBq/m2 (north-eastern part of town, 2 km from the unit accordingly. For the moment of the evacuation dated April 27, deposition values were about 90 percent of these values.

    Full Text Available Três experimentos foram realizados para avaliar os efeitos de dietas formuladas com 53% de trigo ou centeio, suplementadas ou não com a enzima xilanase (0,06%, sobre a digestibilidade de nutrientes e a energia metabolizável das dietas e sobre o desempenho e desenvolvimento do trato digestivo de frangos de corte. Como testemunha foi usada uma dieta com 53% de milho. No primeiro experimento, as digestibilidades da matéria seca, matéria orgânica e gordura e energia metabolizável corrigida para o nitrogênio (EMAn das dietas com centeio foram menores que daquelas com trigo (2.556 kcal/kg vs 2.842 kcal/kg e menores no conjunto dessas dietas que na dieta com milho (2.684 kcal/kg vs 3.010 kcal/kg. A digestibilidade da matéria orgânica e a EMAn das dietas com centeio também foi inferior às da dieta com trigo. A suplementação com xilanases não afetou a utilização digestiva das dietas com centeio ou com trigo. No segundo experimento, nos frangos alimentados com as dietas com centeio, o menor ganho de peso e consumo de EMAn e a pior conversão alimentar ocorreram entre os 8 e os 35 dias de idade. A conversão alimentar foi de 2,17 para as dietas com centeio e 1,88 para a dieta com milho. A adição de xilanases às dietas com centeio ou trigo não melhorou a conversão alimentar. Nos frangos alimentados com as dietas com centeio durante 31 dias, o duodeno-jejuno e íleo foram maiores e o rendimento de carcaça menor que nos frangos alimentados com a dieta testemunha (71,6% vs 74,4%. As dietas com trigo não afetaram essas características.

    Acidification of wheat bread (WBS), rye bread (RBS) and fresh biowaste suspensions (FBS), leading to lactate+acetate, lactate+acetate+n-buyrate, and acetate+propionate+n-butyrate, respectively, and biogas production as well as population dynamics were investigated. Co-fermentation of FBS (14 kg m(-3) d(-1) organic loading rate (OLR)) with WBS or RBS was stable up to an OLR of 22 kg m(-3) d(-1) and resulted in up to 3 times as much biogas. During co-fermentation at more than 20 kg m(-3) d(-1) OLR the total population increased more than 2-fold, but the originally low share of propionate-oxidizing bacteria significantly decreased. The proportion of methanogens also decreased. Whereas the proportion of Methanosarcinales to Methanomicrobiales in biowaste and biowaste+WBS remained constant, Methanosarcinales and in particular Methanosaeta spec. in the biowaste+RBS assay almost completely disappeared. Methanomicrobiales increased instead, indicating propionate oxidation via acetate cleavage to CO2 and hydrogen. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The amount of solid waste generated in developing countries is rising from time to time due to economic growth, change in consumer behavior and lifestyles of people. But it is hard to manage and handle the increase of solid waste with existing waste management infrastructure. Thus, the management system of solid waste is very poor and become a serious problem. The main purpose of this study is to quantify the volume of solid waste generated and investigate factors affecting generation and disposal of wastes in the study area. The result of this study indicated that total waste generated from households was about 97.092kg/day.Furthermore, the study reveals that the solid waste generation rate of the town is 0.261kg/person/day.About 57.5% of solid waste is properly disposed of to landfill site whereas the remaining 42.5% is illegally dumped at the roadsides and open fields. Implication Statement Nowadays, in developing countries there is high concentration of people in urban areas and cause for the generation of enormous concentration of municipal waste in urban areas. Therefore this finding will be important for various policy makers and town planners. It may also serve as a benchmark for the municipal authorities of the town for whom the problem is still invisible and negligible and can push environmental protection authorities to reexamine the implementation of their policies and strategies with regard to the broader issues of human and environmental health condition of town dwellers.

    1994-07-01

    This report presents the methods used and the results obtained from an investigation of relationships between energy use for transport and the physical urban structure of 22 towns in Denmark, Iceland, Norway and Sweden. It is found that urban planning is very important for the inhabitants' average energy use for transport. High population density in the inner and central areas of a town tends to reduce the energy use. The composition of trades and the commuting frequency between the town and its surroundings affect the energy use to the same degree as does the urban planning. The energy data are based on the oil companies' information on the sales of gasoline and auto diesel oil from the filling stations in each town and on the public transport companies' information on the energy use of their vehicles. The energy data are combined with physical and socio economical characteristics of each town.

    Full Text Available One of the potential raw materials which could be used for production of food with added nutritional value is tomato pomace, a by-product from tomato processing. On the other hand, requirements of consumers for diverse food with potential for health benefits impose the need for creation of products made from different cereals. In this respect, the aim of this study was to evaluate the influence of addition of dried tomato pomace on the physical and sensory properties of whole grain rye flour cookies. The whole grain rye flour was substituted with tomato pomace powder in two levels (15% and 25% in the standard formulation of short-dough cookie. The quality of final products was evaluated by instrumental and sensory methods. The results clearly demonstrated that redness (+a* and yellowness (+b* were highly influenced by level of tomato pomace in the cookie formulations due to its content of carotenoid pigments. The spread factor of the cookies made with addition of tomato pomace powder was higher than the control sample. Hardness of the cookie samples decreased for approximately 50% for the cookie sample with 25% tomato pomace level substitution when compared with control sample. According to the results of sensory analysis, substitution level of 15% caused decrease of surface roughness, fracturability, and granularity, as well as increase of caramel flavour intensity. Substitution level of 25% caused higher degree of cookie softening and more pronounced tomato flavour.

    2012-10-01

    The towns of the Swahili coast of East Africa are widely acknowledged as the remains of a maritime society whose relationship with the ocean was fundamental to their economy and identity. Yet research that links the terrestrial environments of the towns to their adjacent maritime landscapes is rare, and urgently required in the light of marine erosional processes unmitigated by human actions. In the Kilwa archipelago of southern Tanzania, survey of the coastal foreshore has documented maritime architecture—particularly a series of coral-built causeways—that serve to link the medieval towns of this area to coastal resources and to expand the limits of the settlements themselves. This paper reports on survey recovering these causeways on Songo Mnara Island, putting the structures into context as part of the broader spatial manifestation of the island's fourteenth-fifteenth century town. Several possible uses of the causeways are discussed, including functional explanations linked to the exploitation of oceanic resources, and more social reasons of territoriality and spatial demarcation.

    The paper is devoted to analysis of the rates and structure of mortality of infants aged under 1 in a town, situated near a nuclear power enterprise (NPE). Altogether 38124 infants born in 1950-1978, were investigated. The dead infants (1160) were divided into 3 groups with relation to their parents' place of work: 1 - infants whose parents worked in the NPE; 2 - infants whose parents worked in town factories and offices; 3 - all infants in the town. The total doses of γ-irradiation for mothers were 10-400 cSv, those for fathers - 30-520 cSv, intrauterine irradiation of a fetus was 0.5-0.55 cSv. The individual effective equivalent dose of irradiation of the residents of the town was 17.3 cSv over 40 years. Occupational γ-irradiation of the parents at doses exceeding the maximum permissible ones in the first 10 years of work at the NPE made no effect on the mortality rates in infants of the first generation

    Full Text Available It is proposed to consider an aggregation of such active elements of town structure as multistoreyed dominants to be used as a basis for designing skyline of a large town on the stage of its general layout. Some interrelated principles, namely: spatial integration, subordination, nature consistence, succession are formulated for improvement of their spatial organization. Every principle takes down any general property of the network of vertical accents which is formed as a system. The obtained principles of the system organization of the multistoreyed dominants are checked while designing Grodno skyline. 

  9. Transfer of Hessian fly resistance from rye to wheat via radiation-induced terminal and intercalary chromosomal translocations

    Friebe, B.; Hatchett, J.H.; Gill, B.S.; Mukai, Y.; Sebesta, E.E.

    1991-01-01

    A new Hessian fly (Mayetiola destructor) resistance gene derived from 'Balbo' rye and its transfer to hexaploid wheat via radiation-induced terminal and intercalary chromosomal translocations are described. Crosses between resistant 'Balbo' rye and susceptible 'Suwon 92' wheat and between the F1 amphidiploids and susceptible 'TAM 106' and 'Amigo' wheats produced resistant BC2F3 lines that were identified by C-banding analysis as being 6RL telocentric addition lines. Comparative chromosomal analyses and resistance tests revealed that the resistance gene is located on the 6RL telocentric chromosome. X-irradiated pollen of 6RL addition plants was used to fertilize plants of susceptible wheats 'TAM 106,' 'TAM 101,' and 'Vona.' After several generations of selection for resistance, new sublines were obtained that were homogeneous for resistance. Thirteen of these lines were analyzed by C-banding, and three different wheat-6RL chromosomal translocations (T) were identified. Wheat chromosomes involved in the translocations were 6B, 4B, and 4A. Almost the complete 6RL arm is present in T6BS · 6BL-6RL. Only the distal half of 6RL is present in T4BS · 4BL-6RL, which locates the resistance gene in the distal half of 6RL. Only a very small segment (ca 1.0 μm) of the distal region of 6RL is present in an intercalary translocation (Ti) Ti4AS · 4AL-6RL-4AL. The 6RL segment is inserted in the intercalary region between the centromere of chromosome 4A and the large proximal C-band of 4AL. The break-points of the translocations are outside the region of the centromere, indicating that they were induced by the X-ray treatment. All three translocations are cytologically stable and can be used directly in wheat breeding programs

    Methodologic choices affect measures of the glycemic index (GI). The effects on GI values of blood sampling site, reference food type, and the number of repeat tests have been insufficiently determined. The objective was to study the effect of methodologic choices on GI values. Comparisons were made between venous and capillary blood sampling and between glucose and white bread as the reference food. The number of tests needed for the reference food was assessed. Rye bread, oatmeal porridge, and instant mashed potato were used as the test foods. Twelve healthy volunteers were served each test food once and both reference foods 3 times at 1-wk intervals in a random order after they had fasted overnight. Capillary and venous blood samples were drawn at intervals for 3 h after each study meal. GIs and their CVs based on capillary samples were lower than those based on venous samples. Two tests of glucose solution as the reference provided stable capillary GIs for the test foods. The capillary GIs did not differ significantly when white bread was used as the reference 1, 2, or 3 times, but the variation was lower when tests were performed 2 and 3 times. Capillary GIs with white bread as the reference were 1.3 times as high as those with glucose as the reference. The capillary GIs of rye bread, oatmeal porridge, and mashed potato were 77, 74, and 80, respectively, with glucose as the reference. Capillary blood sampling should be used in the measurement of GI, and reference tests with glucose or white bread should be performed at least twice.

    University Park, Maryland (“UP”) is a small town of 2,540 residents, 919 homes, 2 churches, 1 school, 1 town hall, and 1 breakthrough community energy efficiency initiative: the Small Town Energy Program (“STEP”). STEP was developed with a mission to “create a model community energy transformation program that serves as a roadmap for other small towns across the U.S.” STEP first launched in January 2011 in UP and expanded in July 2012 to the neighboring communities of Hyattsville, Riverdale Park, and College Heights Estates, MD. STEP, which concluded in July 2013, was generously supported by a grant from the U.S. Department of Energy (DOE). The STEP model was designed for replication in other resource-constrained small towns similar to University Park - a sector largely neglected to date in federal and state energy efficiency programs. STEP provided a full suite of activities for replication, including: energy audits and retrofits for residential buildings, financial incentives, a community-based social marketing backbone and local community delivery partners. STEP also included the highly innovative use of an “Energy Coach” who worked one-on-one with clients throughout the program. Please see www.smalltownenergy.org for more information. In less than three years, STEP achieved the following results in University Park: • 30% of community households participated voluntarily in STEP; • 25% of homes received a Home Performance with ENERGY STAR assessment; • 16% of households made energy efficiency improvements to their home; • 64% of households proceeded with an upgrade after their assessment; • 9 Full Time Equivalent jobs were created or retained, and 39 contractors worked on STEP over the course of the project.

    The goal of this paper is to point out the types of spatial changes that the small towns located in Krakow’s range of influence are currently undergoing, as well as what are the consequences of the various types of changes in these towns. The author asks the question whether the current changes seen in small towns that are under the influence of Krakow can be described as sustainable development - at the basis of which is the increasing of the quality of the functional and spatial structure of a town while preserving its qualities and character - or, on the contrary, that it is more appropriate to describe the changes in the spatial structure of towns as an expansion, which is related only to an increase in their surface area or an increase in the density of their built environment? An attempt has also been made to determine the cause of these changes. An analysis of a set of towns in terms of their accessibility in relation to Krakow, as well as the demographic changes in towns in recent years, has been carried out. This research was useful in determining the dynamic of urban changes or their stagnation. Afterwards, groups of towns with varying degrees of transformation (towns that have been intensively transformed, towns with a balanced degree of spatial changes and towns which remain on the side-lines) were established. In addition, various forms of changes were defined - ranging from cities which register an increase in attractiveness and the changes that it brings while preserving their qualities in accordance with the principles of sustainable development, to settlements which are losing their small-town character as a result of intensive change, at the same time undergoing unification both in terms of space and form of use. From among the groups of towns, example which most fully illustrate the varying degrees and character of the changes of small towns in the area of Krakow has been selected. Based on the research that has been conducted, we can state

    Full Text Available Bacterial artificial chromosome (BAC clones have proven invaluable for genetic manipulation of herpesvirus genomes. BAC cloning can also be useful for capturing representative genomes that comprise a viral stock or mixture. The Towne live attenuated cytomegalovirus vaccine was developed in the 1970s by serial passage in cultured fibroblasts. Although its safety, immunogenicity, and efficacy have been evaluated in nearly a thousand human subjects, the vaccine itself has been little studied. Instead, genetic composition and in vitro growth properties have been inferred from studies of laboratory stocks that may not always accurately represent the viruses that comprise the vaccine. Here we describe the use of BAC cloning to define the genotypic and phenotypic properties of viruses from the Towne vaccine. Given the extensive safety history of the Towne vaccine, these BACs provide a logical starting point for the development of next-generation rationally engineered cytomegalovirus vaccines.

Given the extensive safety history of the Towne vaccine, these BACs provide a logical starting point for the development of next-generation rationally engineered cytomegalovirus vaccines.

  2. Town Centre Redevelopment Strategies

    Vagnby, Bo Hellisen

    After many years of urban growth Danish downtowns are facing some important choices. Shall the stake one-sidedly be on the town centres as driving forces for growth and 'city marketing', or do they still have a role to play in a broader socio-economic context? In the paper we look back on eight...... as slum clearence and urban renewal. To a certain extent parallels are drawn to international experiences, especially where these are of such a nature that they can be assumed transferred to Danish connctions. Conclusively, the strategies are discussed in the light of the turn of Danish urban planning...

    2018-04-01

    Municipal wastewater treatment is energy-intensive. This high energy consumption causes high sewage treatment plant operating costs and increases the energy burden. To mitigate the adverse impacts of China’s development, sewage treatment plants should adopt effective energy-saving technologies. Artificial fortified natural water treatment and use of activated sludge and biofilm are all suitable technologies for small-town sewage treatment. This study features an analysis of the characteristics of small and medium-sized township sewage, an overview of current technologies, and a discussion of recent progress in sewage treatment. Based on this, an analysis of existing problems in municipal wastewater treatment is presented, and countermeasures to improve sewage treatment in small and medium-sized towns are proposed.

    Local governments attempting to respond to environmental change face an array of challenges. To better understand policy responses and factors influencing local government capacity to respond to environmental change, we studied three environmental issues affecting rural or peri-urban towns in different regions of New York State: climate change in the Adirondacks (n = 63 towns), loss of open space due to residential/commercial development in the Hudson Valley (n = 50), and natural gas development in the Southern Tier (n = 62). Our analysis focused on towns' progression through three key stages of the environmental policy process (issue awareness and salience, common goals and agenda setting, policy development and implementation) and the factors that affect this progression and overall capacity for environmental governance. We found that-when compared to towns addressing open space development and natural gas development-towns confronted with climate change were at a much earlier stage in the policy process and were generally less likely to display the essential resources, social support, and political legitimacy needed for an effective policy response. Social capital cultivated through collaboration and networking was strongly associated with towns' policy response across all regions and could help municipalities overcome omnipresent resource constraints. By comparing and contrasting municipal responses to each issue, this study highlights the processes and factors influencing local government capacity to address a range of environmental changes across diverse management contexts.

    Genotyping by sequencing (GBS) is an efficient method of genotyping in numerous plant species. One of the crucial steps toward the application of GBS markers in crop improvement is anchoring them on particular chromosomes. In rye (Secale cereale L.), chromosomal localization of GBS markers has not yet been reported. In this paper, the application of GBS markers generated by the DArTseq platform for extending the high-density map of rye is presented. Additionally, their application is used for the localization of the Rfc1 gene that restores male fertility in plants with the C source of sterility-inducing cytoplasm. The total number of markers anchored on the current version of the map is 19,081, of which 18,132 were obtained from the DArTseq platform. Numerous markers co-segregated within the studied mapping population, so, finally, only 3397 unique positions were located on the map of all seven rye chromosomes. The total length of the map is 1593 cM and the average distance between markers is 0.47 cM. In spite of the resolution of the map being not very high, it should be a useful tool for further studies of the Secale cereale genome because of the presence on this map of numerous GBS markers anchored for the first time on rye chromosomes. The Rfc1 gene was located on high-density maps of the long arm of the 4R chromosome obtained for two mapping populations. Genetic maps were composed of DArT, DArTseq, and PCR-based markers. Consistent mapping results were obtained and DArTs tightly linked to the Rfc1 gene were successfully applied for the development of six new PCR-based markers useful in marker-assisted selection.

    Full Text Available The objective of this study was to evaluate and characterize the fish consumption profile in the town of Lavras, Minas Gerais. A descriptive-quantitative study was conducted. A structured questionnaire elaborated using previously formulated questions and answers was used for data collection. The questionnaire was applied between March and May 2014 to the household reference person. A total of 402 households were sampled. The data were analyzed by analysis of the distribution of frequencies using the SPSS program. The results showed that fish meat occupied fourth place in the preference of household consumption in the town of Lavras, after beef, poultry and pork meat. It was also observed that fish is usually purchased as fillet and is consumed occasionally in the households. The price is an important factor for the choice of meat. Most respondents prefer to consume fried fish. The species most appreciated by consumers in the town of Lavras is Dourado. Most respondents usually buy less than 2.0 kg/household/year.

  13. GPS Imaging of Time-Variable Earthquake Hazard: The Hilton Creek Fault, Long Valley California

    Hammond, W. C.; Blewitt, G.

    2016-12-01

    The Hilton Creek Fault, in Long Valley, California is a down-to-the-east normal fault that bounds the eastern edge of the Sierra Nevada/Great Valley microplate, and lies half inside and half outside the magmatically active caldera. Despite the dense coverage with GPS networks, the rapid and time-variable surface deformation attributable to sporadic magmatic inflation beneath the resurgent dome makes it difficult to use traditional geodetic methods to estimate the slip rate of the fault. While geologic studies identify cumulative offset, constrain timing of past earthquakes, and constrain a Quaternary slip rate to within 1-5 mm/yr, it is not currently possible to use geologic data to evaluate how the potential for slip correlates with transient caldera inflation. To estimate time-variable seismic hazard of the fault we estimate its instantaneous slip rate from GPS data using a new set of algorithms for robust estimation of velocity and strain rate fields and fault slip rates. From the GPS time series, we use the robust MIDAS algorithm to obtain time series of velocity that are highly insensitive to the effects of seasonality, outliers and steps in the data. We then use robust imaging of the velocity field to estimate a gridded time variable velocity field. Then we estimate fault slip rate at each time using a new technique that forms ad-hoc block representations that honor fault geometries, network complexity, connectivity, but does not require labor-intensive drawing of block boundaries. The results are compared to other slip rate estimates that have implications for hazard over different time scales. Time invariant long term seismic hazard is proportional to the long term slip rate accessible from geologic data. Contemporary time-invariant hazard, however, may differ from the long term rate, and is estimated from the geodetic velocity field that has been corrected for the effects of magmatic inflation in the caldera using a published model of a dipping ellipsoidal

    2015-01-01

    Full Text Available Škofja Loka is one of the best preserved medieval towns in Slovenia. In 1987 it was declared a cultural monument. In this article I will discuss the reasons why the town does not live in the tourist sense in spite of a huge heritage potential. The local population often sees living in the old part of the town as an obstacle, tourists do not stay in the town for more than two hours, important events at- tract a large number of people only a few times per year which is not enough for the old part of the town to live on tourism, and consequently it is slowly dying. Why is Škofja Loka a town which is not able to apply its own cultural heritage and create a very interesting and attractive tourist story? Škofja Loka does have stories which represent timelessness and the ability to connect different time periods. I linked its potential different brand name and I will show how the heritage can be a potential and basis for the development of town tourism, not linked only to a few one-off events.

  17. LIKE TURTLES IN THEIR SHELLS?: CIVIC WITHDRAWAL AMONG YOUNG PEOPLE IN DIVERSE SMALL TOWNS

    Directory of Open Access Journals (Sweden)

    J. Celeste Lay

    2012-04-01

    Full Text Available Robert Putnam has argued that ethnic diversity is associated with declines in civic engagement because when faced with diversity, a natural reaction is to retreat into oneself. Goals: This paper tests this proposition by looking at adolescents in small towns that have recently undergone “rapid ethnic diversification”. Immigrants and refugees from Latin America and Southeast Asia have migrated to these small, ethnically homogeneous towns. Methods: I utilize a panel study in which adolescents in five small Iowa public high schools were surveyed at the beginning and the end of an academic year. Conclusions: This paper shows very little evidence of a lasting negative effect of ethnic diversity on civic engagement. In the first wave, young people in the diverse towns have lower levels of political knowledge and trust than those in predominantly-White towns, but they also have higher levels of participation in school activities. At the end of the year, these differences have been alleviated.

  1. The powdery mildew resistance gene Pm8 derived from rye is suppressed by its wheat ortholog Pm3.

    The powdery mildew resistance gene Pm8 derived from rye is located on a 1BL.1RS chromosome translocation in wheat. However, some wheat lines with this translocation do not show resistance to isolates of the wheat powdery mildew pathogen avirulent to Pm8 due to an unknown genetically dominant suppression mechanism. Here we show that lines with suppressed Pm8 activity contain an intact and expressed Pm8 gene. Therefore, the absence of Pm8 function in certain 1BL.1RS-containing wheat lines is not the result of gene loss or mutation but is based on suppression. The wheat gene Pm3, an ortholog of rye Pm8, suppressed Pm8-mediated powdery mildew resistance in lines containing Pm8 in a transient single-cell expression assay. This result was further confirmed in transgenic lines with combined Pm8 and Pm3 transgenes. Expression analysis revealed that suppression is not the result of gene silencing, either in wheat 1BL.1RS translocation lines carrying Pm8 or in transgenic genotypes with both Pm8 and Pm3 alleles. In addition, a similar abundance of the PM8 and PM3 proteins in single or double homozygous transgenic lines suggested that a post-translational mechanism is involved in suppression of Pm8. Co-expression of Pm8 and Pm3 genes in Nicotiana benthamiana leaves followed by co-immunoprecipitation analysis showed that the two proteins interact. Therefore, the formation of a heteromeric protein complex might result in inefficient or absent signal transmission for the defense reaction. These data provide a molecular explanation for the suppression of resistance genes in certain genetic backgrounds and suggest ways to circumvent it in future plant breeding. © 2014 The Authors The Plant Journal © 2014 John Wiley & Sons Ltd.

  2. Spatial Analysis of Urban Master Plans of Towns in North-Eastern Poland in the Context of Urban Revalorisation

    Science.gov (United States)

    Zagroba, Marek; Klopotowski, Maciej

    2017-12-01

    The research subject raised in this study is the urban structure of small towns in Warmia, a region rich in history, situated in the north-eastern Poland. This area, together with the neighbouring region of Mazury, is referred to as the Land of a Thousand Lakes. The historical events, such as the conquest of this territory by the Teutonic Order in 13th century, gave rise to the foundation of twelve towns in Warmia, which have survived until our time. Of these settlements, only one, which is Olsztyn, grew to a larger size over the centuries and eventually became the capital of Warmia. The others are still small towns, with a population from a few to less than twenty thousand inhabitants. The policy and economic goals of the Teutonic Order underlay the spread of a uniform type of urban master plan in the entire region. The establishment of urban centres was dictated by military considerations - all towns had fortified castles and were 15-30 km distant from one another, which stemmed from the organisation of the Teutonic State. The location of new towns in Warmia coincided in time with the general urban planning principles governing urban development in the Middle Ages. The medieval towns, which grew on the foundations of ancient cultures, were developed on a regular grid of streets, delineating land lots for compact town houses and a central square serving as a market place. Within this structure, the town’s most significant spatial dominants, such as a town hall, a church and a fortified castle, were situated. The castle often stood on the outskirts of a town, as it had to be connected to the town’s fortifications. The location of medieval towns in Warmia proceeded according to a similar concept. All these towns are distinguished by characteristically medieval, regular urban layouts, which - while being similar - have certain intrinsic features. Differences can be seen in the design of main streets, the size and proportions of market squares, the ways in which

    Full Text Available Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development of urban ecology locally and globally. Different approaches have been used in the study of urban ecology of different urban areas in South Africa. Cape Town is situated in a biodiversity hotspot and is the only South African city which includes a national park. As a result the urban ecological studies were mainly driven by urban nature conservation concerns. In other cities such as Durban, open space planning and environmental management were the major issues which focused ecological studies on urban areas whereas other studies of urban areas in the Eastern Cape and North-West provinces included private and public open spaces and man-made habitats. We reflect on the Cape Town studies in a South African context and highlight conservation of biodiversity, protection of ecosystem services, management of control measures, and the conflict between humans and nature. A brief synthesis has also been given of South African urban ecological research in general.

    2017-11-01

    Full Text Available Building new towns seems to be a rational regionalization approach that releases pressure from overly burdened large cities. This strategy was developed in Western Europe in the middle of twentieth century. Since the 1990s, the European new town model has been widely implemented in China. However, the author questions the feasibility of the large-scale, hasty new town developments. The study of worldwide new town experiences, especially European and Chinese cases, demonstrates that many new towns in fact have difficulty in achieving a real sense of urban quality and vitality. So far, few research projects have been conducted to evaluate and develop solutions for this problem. The purpose of this research project is therefore to identify the spatial and non-spatial factors and conditions that facilitate the development of urban vitality in new towns. It is aimed to reveal the impacts of spatial design, urban planning and governance approaches on the degree and patterns of local urban life of new towns in China and in the Netherlands. The generated knowledge of this research project helps develop not only a better understanding of the main problems of new towns, but also spatial strategies with the aim to enliven new towns and other types of (suburban areas as well. The central research question is approached through literature review and case studies. The literature review provides a critical re-evaluation of the scientific validation of the new town model, especially the notion of town self-containment in economic terms. The relevant theories under study mainly include regional science and economic geography. The literature review also clarifies the general definition of urban vitality and its distinct meanings in different socio-economic and political backgrounds of the two societies, sets up the quantitative measurements methodology, and identifies a preliminary framework of spatial factors and conditions. As it turns out, the key indicators

    Full Text Available The topic of this volume is a result from The Contemporary City in Serbia and Bulgaria: Processes and Changes, a bilateral project of the Institute of Ethnography of the Serbian Academy of Sciences and Arts and the Institute of Ethnology and Folklore Studies with Ethnographic Museum of the Bulgarian Academy of Sciences (2014-2016. The six papers offer a comparative view of current social processes in two neighbouring Balkan countries, linked by numerous historical and political experiences. Comparative research into societal trends enables a more thorough understanding and monitoring of global processes. In today’s increasingly globalised and glocalised world, towns experience sudden changes and it is in the towns that these changes are most vividly to be seen. The focus of our research is on the dynamism of the contemporary town, on processuality and changes in societal practices. Ana Luleva examines life in the small town of Nessebar in southeast Bulgaria, which has been on the UNESCO World Heritage list since 1983. The protection, management and presentation of Nessebar’s cultural heritage are highly complex issues, further complicated by the problem of collision with the interests of the inhabitants. The author analyses the relations between the various factors - the state administration, municipal authorities and the local population. Here the tourist industry, investment interests, corrupt institutions and civil society all play their part. Ivanka Petrova chose to research Belogradchik, a small town in northwest Bulgaria. Petrova investigates how local social and cultural resources are used in the work of a family tourist enterprise. The author looks for answers to questions such as: how its members identify with the town and its culture and how the work of the enterprise fits into the Belogradchik local context. At the focus of her paper are current societal practices: the local urban economy and the production of images and symbols

    In the present study, selenium-enriched plant biomass was investigated to evaluate the ability of rye seedlings to take up, and assimilate, inorganic selenium. Two different analytical approaches were used. Electrophoretic separation (SDS-PAGE) of proteins extracted from {sup 75}Se-labelled biomass was used to investigate the biotransformation of selenite into organic forms of the element. Ion-pair chromatography coupled with ICP-MS detection was chosen for the analysis of selenium species, enzymatically extracted from the plant biomass. The results of three enzymatic hydrolysis procedures and three sequential enzymatic extractions procedures are compared. The most effective single extraction was proteolysis (using protease type XIV), giving an overall extraction efficiency of 48%. However, for combinations of enzymes, the most effective was cellulase (Trichoderma viride) followed by sequential extraction of the solid pellet using protease type XIV, giving an extraction efficiency of 70%. The complementary data from the electrophoretic fractionation of proteins, and the HPLC separation of Se-species in the proteolytic digests, reveal the existence of large number of selenium-containing compounds in the rye seedling plant biomass. The results showed the complete biotransformation of inorganic selenium into organic forms during germination of the rye seedlings. HPLC-ICP-MS analysis of extracts from the plant biomass did not show the presence of selenate or selenite. At the time of this study, the lack of suitable organic-MS facilities meant that it was not possible to characterise them fully. However, the data does show that a combination of different enzymes, rather than just the commonly-used protease, should be considered when developing an extraction strategy for selenium in different food types to those already reported in the literature.

    The aim was to evaluate a number of possibilities for reducing energy consumption and thus air pollution caused by freight transport in urban areas. The Danish towns of Vejle and Roskilde were taken as examples and the two towns were compared with regard to the town plan, use of land area, the road network, amount of traffic and commercial structure. Economical aspects and the most important initiatives for improvements, including a decrease in traffic accidents, are discussed. These initiatives are coordination of transportation by firms, more drivers using the same vehicles, less frequent deliveries, optimazation of route planning, car sharing, special routes for lorries, traffic and speed control, better siting of new transport functions, re-siting of firms dependent on freight transport, the use of smaller vehicles where possible, no transport of people in trucks or vans, less use of bicycles for transporting messages, more use of underground pipes for transport of materials, lifting equipment for smaller vans and trucks, lifting equipment that is more flexible, motors turned off when loading and loading, reduction of emballage volume, and a more careful way of driving which can help to reduce energy consumption. A computer programme was constructed in order to calculate energy consumption in these relations, emission of hydrocarbons, carbon monoxide, nitrogen oxides and particles, transportation costs and number of traffic accidents. Results are presented in detail and discussed. (AB) (78 refs.).

    For the purpose of promoting the introduction of new energy and enhancing the awareness of it in Daito Town, Shimane Prefecture, an investigational study was conducted of the energy demand of the town, existence amount of new energy, project for new energy introduction, etc., and a new energy vision was worked out. The energy demand amount of the town was estimated at 141,437 x 10{sup 6} kcal, and the amount of CO2 emitted from this was 15,787 t-C. By sector, the energy demand amount consisted of 38% in the transportation sector, 37% in the commercial/residential sector and 26% in the industrial sector. As the project for new energy introduction, the following were studied: formation of the zone for learning new energy; introduction of solar system/thermoelectric supply system to the center for providing school lunch; introduction of thermoelectric supply system by stockbreeding biomass gas turbine; introduction of large wind power system; introduction of micro hydraulic power system/heat pump using waste hot water as heat source to tourist facilities/townspeople exchange facilities; introduction of photovoltaic power system/solar system/cogeneration system/solar car to public facilities; district thermoelectric supply using wood biomass.

    Rapid urbanization in China has triggered the conversion of land from rural to urban use, particularly the conversion of rural settlements to town land. This conversion is the result of the joint effects of the geographic environment and agents involving the government, investors, and farmers. To understand the dynamic interaction dominated by agents and to predict the future landscape of town expansion, a small town land-planning model is proposed based on the integration of multi-agent systems (MAS) and cellular automata (CA). The MAS-CA model links the decision-making behaviors of agents with the neighbor effect of CA. The interaction rules are projected by analyzing the preference conflicts among agents. To better illustrate the effects of the geographic environment, neighborhood, and agent behavior, a comparative analysis between the CA and MAS-CA models in three different towns is presented, revealing interesting patterns in terms of quantity, spatial characteristics, and the coordinating process. The simulation of rural settlements conversion to town land through modeling agent decision and human-environment interaction is very useful for understanding the mechanisms of rural-urban land-use change in developing countries. This process can assist town planners in formulating appropriate development plans.

    The problems of Visaginas are specific and, first of all, connected with the operation of the Ignalina nuclear power plant and cultural development of Visaginas ethnic minorities, lack of skilled specialists employed in different spheres. Some difficulties we have with the learning of the official language. A strong well-reasoned opinion of the scientists corresponds to our practical directions: the problems of the town of Visaginas are not only the problems of its inhabitants but also a composite part of the problems of the Ignalina nuclear power plant region.

    Doughs supplemented with endoxylanase (XYL) and varying amounts of microbial transglutaminase (TG) were analyzed by sequential protein extraction, quantitation of protein fractions and protein types, and determination of water-extractable arabinoxylans. With increasing TG activity, the concentration of prolamins and glutelins decreased and increased, respectively, and the prolamin-to-glutelin ratio strongly declined. The overall amount of extractable protein decreased with increasing TG level showing that cross-linking by TG provided high-molecular-weight protein aggregates. The decrease of the high-molecular-weight arabinoxylan fraction and the concurrent increase of the medium-molecular-weight fraction confirmed the degradation of arabinoxylans by XYL. However, XYL addition did not lead to significant improved cross-linking of rye proteins by TG. Volume and crumb hardness measurements of bread showed increased protein connectivity induced by XYL and TG. Significant positive effects on the final bread quality were especially obtained by XYL addition.

    Full Text Available The paper looks at stylistic differences between four translations of J. D. Salinger’s Catcher in the Rye – two Slovene translations, a Serbo-Croatian, and an Italian translation. Firstly, stylistic components relevant to the novel in question are identified. In this respect, the translation of teenage speech and idiom appears to be not only the most conspicuous stylistic feature of the original but also the hardest to translate. Secondly, the ways in which the different translations have rendered certain formal and lexical features of style are compared by determining and describing their function. A large number of examples have been submitted to critical scrutiny, of which only a few representative ones are listed and explained in the paper. Finally, this paper points to some particular difficulties of the four translators in their attempts to reproduce the stylistic components of the original.
