Authors: Yildirim Ertan , Dursun Atilla , Kumlay Metin A. , Güvenç Ísmail
Published: December 2013

This research was conducted to determine the effects of two biostimulants (humic acid and biozyme) or three different salt (NaCl) concentrations at the temperature 10, 15, 20 and 25°C on parsley, leek, celery, tomato, onion, lettuce, basil, radish and garden cress seed germination. Two applications of both biostimulants increased seed germination of parsley, celery and leek at all temperature treatments. Germination rate decreased depending on high salt concentrations. At different salt and temperature levels garden cress was characterised by the highest germination percentage compared to other vegetable species.Interactions between NaCl concentrations and temperatures, as welI as biostimulants and temperatures were significant at p=0.001 in for all vegetable species except onion in NaCl concentrations and temperatures compared to that of the control.

Authors: Zając Tadeusz , Góral Halina , Witkowski Robert , Spiss Ludwik
Published: December 2013

Two red clover breeding strains with elongated flower heads, developed by one of the authors (H.Góral), were studied for forage and seed yield and compared to the standard cultivar 'Nike'. In addition, six morphological shoot traits were measured and their interrelations were computed. The leaf area index (LAI) of successive cuts in two harvest years was determined on the basis of shoot density and leaf area of individual shoots. All three genotypes exhibited a high leaf area on shoots and a very high forage productivity. Among the morphological traits only shoot height could be a good selective criterion because it is easily measured, is significantly associated with shoot weight and shoot leaf area and its variation is low. Both strains, particularly the one with longer inflorescences belong to short-lived red clover forms giving satis factory forage and seed yields in the first harvest year. Depending on the strain the number of seeds per elongated inflorescence in the first harvest year was higher by 92 and 42% compared to that of a standard cultivar.
Ray florets with closed tubular corollas (RC type), tubular-ligulated (RJ type) and ligulated (J type) in China aster (Callistephus chinensis (L.)Nees). Heredity
Authors: Wosińska Alicja
Published: December 2013

The improper description and classification of two Polish cultivars of China aster ('Roma' and 'Srebrzysta Gwiazdka') were corrected. A new type of ray florets with tubular-ligulated (RJ type) and closed tubular (RC type) corollas was described. The type of heredity of the above mentioned types of florets and florets with ligulated corollas was determined. The work is based on our own material: radiomutant MG and its offspring as well as the F1 </sub; and F2 </sub; generations of hybrids obtained after crossing three cultivars: 'Goplana' x 'Roma' and 'Goplana' x 'Srebrzysta Gwiazdka' (i.e. J type x RC type). It was observed that the RJ type of corollas did not remain in the type. In the offspring of plants with such florets, always three types of segregants were present: plants with ray florets with ligulated, tubular - ligulated and tubular corollas. It was proved that it corresponds to the 1 :2: 1 ratio. It means that the formation of the RJ type corollas results from the presence of both alleles in the heterozygote. It was proposed to mark the gene conditioning the ligulated corolla form with the symbol Lt</sub; (from Liguliformes) and the total corolla accretion with the symbol l1 </sub;. Thus the described phenotypes correspond to the following genotypes: Lt</sub;Lt</sub; - determines the appearance of ligulated corollas, Lt</sub;lt</sub; - tubular - ligulated corollas and lt</sub;lt</sub; - closed tubular corollas.

Authors: Kraska Piotr , Pałys Edward
Published: December 2013

The purpose of this work was to determine the influence of conventional and ploughless tillage systems upon infestation in two differentiated fertilization and plant protection levels on light soil. Before harvest winter rye there was determined weed infestation of square-frame method. There were estimated weed species composition and air dry matter of weeds in two randomly selected place. Number of monocotyledonous weeds, total weeds and dry matter of weeds was higher on the objects with ploughless tillage system compared with conventional tillage. Intensive fertilization and plant protection decreased number of dicotyledonous weeds in canopy of winter rye. Conventional tillage system decreased Apera spica-venti occurrence in a canopy of winter rye and increased number of Plantago major plants. Intensive level of fertilization and plant protection decreased weed infestation first of all through Matricaria maritima.

Published: December 2013

The research was conducted in the years 1999-2001. The aim of the research was to determine the health condition of overground parts and seeds of white niuslard (Sinapis alba L.) cv. Metex and chinese mustard (Brassica juncea L.) cv. Małopolska. In all the years of the research alternaria blight was found on the leaves of white mustard which injury index ranged from 5,6% in 2001 to 17,6% in 200O. The most dangerous disease of chinese mustard also was alternaria blight and its symptoms were found on leaves and siliques. The strongest infection of leaves was in 2000 (50%) and the weakest in 2001 (6,7%). In all the years of the research siliques were rather weak infected (50-8,89%). Besides powdery mildew was found on chinese mustard which injury index ranged from 0,3% in 1999 to 32,3% in 2000. Intensity of diseases was affected generally by the weather conditions. From the seeds of white mustard and chinese mustard were isolated respectively 263 and 137 colonies. Alternaria alternata was the most numerous species which makes respectively 60,9% and 42,3% isolates. Among the fungi pathogenic for white and chinese mustard were also isolated: A. brassicae, Botrytis cinerea and Rhizoctonia solami.

Authors: Pałys Edward , Kuraszkiewicz Robert , Kraska Piotr
Published: December 2013

Germination capacity, length of roots and seedlings and air-dry matter of plants of soybean, cucumber, buskwheat, winter wheat and white mustard were estimated in four soil material: bare soil and grass-covered soil from a side-space ofroads with heavy traffic. soil from a farming field and washed, calcinated sand (pure sand). Highest germination capacity of investigated plants was found on pure sand. Seedlings germinated on soil from the grassy side space of the street had longer aboveground parts in comparison with those germinating on other soil material. Significantly smaller length of abovegro und parts of seedlings were found on the object with washed and calcinated sand. On the pure sand, plant seedlings formed higher air-dry matter in comparison with the soil from a farming field. Independently of soil material, soybean and winter wheat seedlings formed the longest roots, aboveground parts and highest content of air-dry matter. On the soil from the grassy side space of the street roots of seedlings were significantly longer than roots of seedlings germinated on soil from a farming field. Greater content of some heavy metals in soil from side space ofthe street had no influence on germination capacity and investigated morphological characters of tested pIants.

Regeneration and growth of peony (Paeonia spp.) in vitro
Authors: Gabryszewska Eleonora
Published: December 2013

Vegetative propagation of peony is usually carried out by grafting onto herbaceous peony roots (tree peony) or by dividing tuberous root clumps (herbaceous peony). However, conventional propagation is time-consuming and too slow for a large production and therefore in vitro methods have been developed. The regeneration ability of different organs of herbaceous and tree peony has been reported in this review. The role of exogenous and endogenous growth regulators in the differentiation and growth of shoots, roots and somatic embryos is presented. The problem of dormancy in the somatic embryos and in the shoots or plants propagated in vitro are also discussed.

Published: December 2013

Our study was carried out with potato plants (Solanum tuberosun L.,cv. Désirée) transformed with the yeast invertase gene under the control of the B33 class I patatin promoter and with the proteinase inhibitor II leader peptide sequence providing for the apoplastic enzyme localization (B33-inv plants) and with the plants transformed with the reporter gene encoding bb-glucuronidase under the control of the 35S CaMV promoter (control plants). Exposure to 5°C during 6 days caused an increase in invertase activity and sugar content in B33-inv leaves in comparison with the control plants. Cell membranes of B33-inv plant cells showed greater cold tolerance under low temperature conditions than control plants that was recorded by electrolyte release. We supposed that higher cold tolerance of B33-inv plants was caused by stabilizing effect of sugar on the membranes, because B33-inv plants differ from the control plants in higher invertase activity, induced by expression of yeast invertase gene, and high content of sugars.
Free proline accumulation in leaves of cultivated plant species under water deficit conditions
Authors: Bandurska Hanna
Published: December 2013

The effect of water deficit caused by soil drought on the content of free proline as well as the degree of cell membrane damages in the leaves of three cultivated plant species having different farm usefulness and water requirements have been studied. The used pIants were: poinsettia (Euphorbia pulcherrima Willd., 'Regina' and 'Cortez') grown for decorative purposes, a green vegetable of broccoli (Brassica oleracea var. botrytis, subvar. cymosa, 'Colonel' and 'Marathon') and a cereal plant of barley (the wild form Hordeum spontaneumm and Hordeum vulgaree 'Maresi'). The examined species differed in the size of the experienced stress. the Iargest RWC reduction was found iii broccoli leaves, while somewhat smaller - in barley. In poinsettia leaves, the reduction of RWC level was not large or did not occur at all. The accumulation of free proline in the species under study was also variable. The largest amount of this amino acid tended to accumulate in broccoli leaves, whereas the increase of its level took place only at a strong dehydration of tissues. The increase of proline level was smaller in barley leaves than in broccoli, but that was found already at a smalI dehydration of tissues. In poinsettia leaves, a several f`old increase of proline level was found at the early stage of the stress. The level of that amino acid gradually increased at consecutive times and did not depend on tissue dehydration. Damage of cell membranes amounted to 8.5-9.5% in barley leaves, about 3% in brocolli and to 0-2.6% in poinsettia. The role of proline in prevention of leaf dehydration and in alleviation of dehydration effects in the studied species has been discussed.

Authors: Król Ewa
Published: December 2013

The possibilities of using antagonistic fungi and bacteria in the limitation of grapevine stems infection by Phomopsis viticola Sacc. were studied. Trichodema koningii Oud., T.viride Persoon ex S.F.,T.harzianum Rifai, Gliocladium catenulatum Gilman and Abbott, G.fimbriatum Gilman and Abbott, Bacillus sp., Pseudomonas fluorescens and five unidentified isolates of bacteria i.e.: 22a, 35, 40, 45, 66 were estimated. It was appeared what Trichoderma spp. were the most effective in protection of grapevine stems against the infection by P.viticola. After these antagonistic fungi were used on protected grapevine canes not numerous necrosis were observed and few cultures of pathogen were reisolated from them. Moreover, Trichoderma spp. survived on the grapevine stems during the period of experiment. The abilities of other microorganisms tested to protect grapevine cuttings against P.viticola infection and to exist on the stems were less than Trichoderma spp.

Published: December 2013

The studies were conducted in the years 1999-2001 in the green areas of Lublin, on the trees of Crataegus x media Bechst. The purpose of the studies was to establish the species composition and the population dynamics of aphids inhabiting hawthorn in the street and park sites. The studies found out the presence of four aphid species on the examined trees, namely Aphis pomi De Geer, aphids from the genus Dysaphis Börn., Ovatus crataegarius (Walk.) and Rhopalosiphum insertum (Walk.). More aphid species and bigger populations were found in the street site (A) as compa red with the park site (B).The weather conditions (air temperatures of over 30°C and stormy rainfalls) limited the population of all aphid species. On the other hand, a mild winter and a warm spring with the rainfalls within the norm caused that the number of aphids decreased considerably.
Aphids (Homoptera, Aphidodea) inhabiting the trees Crataegus x media Bechst. in the urban green area. Part II. Domination and frequency of aphids, their enemies and the damage caused by aphids
Authors: Sławińska Aneta , Jaśkiwicz Bożena
Published: December 2013

The studies were conducted in Lublin in the years 1999-2001 in two sites (street and park ones) on the trees Crataegus x inedia Bechst. The purpose was to determine the domination and frequency of particular aphid species, their effect on the decorative character of plants as well as the occurrence of the aphidophagous in aphid colonies. It was found out that A. pomi was the dominating species in both sites. The decorative character of the studied trees was lowered by aphids A. pomi and aphids from the genus Dysaphis. Aphids from the genus Dysaphis also caused changes in the chemical composition of the injured plant parts. The presence of predatory arthropods was observed in aphid colonies occurring on hawthorn. The most numerous of these were the larvae of Syrphidae and Coccinellidae. The culture of parasitized aphids gave numerous flights of parasitoids and hyperparasitoids. Greater number of both predators and parasitoids of I and II grades were observed in the street site as compared to the park site.
Analysis of linseed (Linum usitatissiumum L.) plant branching as related to variability and interdependence of traits
Authors: Zając Tadeusz
Published: December 2013

Branching process of two linseed cultivars ('Hungarian Gold' and 'Opal') was analysed each year of vegetation between 1999 and 2002 characterised by different weather course. The estimation included also the extent and variability of selected morphological traits and structural traits. as well as correlation between them. On the basis of biometric measurements the hierarchy of plant shoots has been established within a plant, and four plant groups were distinguished: 1-. 2-, 3- and 4-shoot plants. It was demonstrated that the intensity of linseed branching depended mainly on young plant planting density and, to a certain extent also the weather conditions in April and May. In the years when the weather course favoured vegetation. between 23 and 40% plants per stand were branched. Beside increasing its productivity linseed branching may also inhibit a development of secondary weed infestation of the canopy. Similar plant groups with analogous shoot hierarchy formed in both linseed cultivars. Bio social position of shoot on a plant determined the extent of its traits. A dominance of the maiii shoot over lateral shoots was marked, especially concerning the number of seed vessels. Particularly big prevalence of the main shoot over lateral ones was visible in 3- and 4-9hoot plants. Lateral shoots had greater variability of morphological traits, especially concerning the number of seed vessels per shoot. Linear, exponential and power interdependencies between traits of linseed cultivars were also revealed.

Published: December 2013

The study on weed infestation of crops in different soils in the protective zone of RPN was conducted in the years 1991-1995. The characterization of weed infestation of winter and spring cereals was based on 306 phytosociological records. made with the use of Braun-Blanquet method. The degree of weed infestation in the fields in the protective zone of RPN depended on environment conditions. Both winter and spring cereals in majority of soils were most infested by: Cenaturea cyanus, Apera spica-venti and Vicia hirsta. In the lightest podsolic soils, made of loose sand and slightly loamy sand. winter and spring cereals were additionally infested by Equisetum arvense and two acidophylic species: Seleranthus annuus and Spergula arvensis. The crops in brown loess soil were infested by Matricaria maritima subsp. inodora. The most difficult weed species in brown soil formed from gaizes and limestone soil were: Convolvulus arvensis, Papaver rhoeas and Galium aparine. Moreover winter cercals in limestone soil showed high or medium infestation with Consolida regalis, Aethusa cynapium, Lathyrus tuberosus and low infestation with Apera spica-venti and Centaurea cyanus. Spring cereals were less infested than winter cereals. Apera spica-venti and Centaurea cyanus were less common with spring cereals than with winter cereals. Also, spring cereals showed high or medium infestation with Convolvulus arvensis. Spring cereals in some soil units were infested by Chenopodium album and Stellaria media. There was also higher infestation of spring cereals in limestone soils with Avena fatua, Veronica persica, Sinapis arvensis and Sonchus arvensis, compared to winter cereals in limestone soils.

The study on weed infestation of root crops in different soils in the protective zone of Roztocze National Park was conducted in the years 1991-1995. As many as 240 phytosociological records, made with the use of Braun-Blanquet method, were taken in potato and sugar beet fields. The number of weed species in sugar beet and potato in the area depended on the soil and type of root crop. In the same environment conditions. the iiuinber of weed species was higher in potato than in sugar beet. The most difficult weed species iii all types of soil were: Chenopodium album, Stellaria media and Convolvulus arvensis. Podsolic soils were highly infested by two acidophylic species: Spergula arvensis and Raphanus raphanistum. Potato in loess soil and brown soil made of loamy sands were highly infested by Echinochloa crus-galli, Equisetum arvense and Galinsoga parviflora. Root crop plantations in brown soils formed from gaizes of granulometric loam texture and limestone soils were infested by: Galium aparine, Sonchus arvensis, Sinapis arvensis and Veronica persica.
Canada thistle phenology in broadbean canopy
Authors: Wesołowski Marian
Published: December 2013

Soine of the developmental stages of Canada thistle - Cirsium arvense (L.) Scop. (I. emergence and early growth, II. shooting, II. budding, IV. flowering, V. fructification, VI. shedding of fruits) on the background of development stages of broad-bean, weeded by herbicides and without that weed-killing substances, were presented in the paper. Phenological observations were carried out on the plants growing on alluvial soil developed from light loam in Zakrz6w near Tarnobrzeg. It was proved that phenological development of Canada thistle, during broad-bean vegetation, depended on course of weather conditions and method of crop care. Emergence of the weed occurred earlier than broad-bean plants during warm and rather dry seasons. In every vegetation period, emergence and early vegetation stage (to 4 leaves seedling) of Canada thistle lasted about 3 months, until broad-bean got full pod setting. During wet and cold season (in 2001) the weed emerged also early under herbicide (Afalon 1,5 kg ha-1) condition. Until to broad-bean harvest, Canada thistle attained the finish developmental stages, that means fruiting and fruit shedding. Herbicide treatment delayed the last two stages and limited fruit shedding by plants of Cirsium arvense.

Equisetum telmateia Ehrh. rather often occurs in agricultural lands communities. According to the literature and one's own original research, one constructs his list which contains 16 communities, associations and subassociations (Vicietum tetraspermae, Aphano-Matricarietum, Lathvro-Melandrietum noctiflori, Echinochloo-Setarietum, Galinsogo-Setarietum, Cirsietum rivularis, Cirsetum rivularis caricetosum hartmanii, Scirpetum sylvatici, community with Mentha longifolia, community ,with Equisetum telmateia, Arrhenatheretum medioeuroaeum, Arrhenatheretum mnedioeuropaeum brizetosum mediae, community with Cirsium oleraceuum, Lolio-Cynosuretum, Valeriano-Caricetum flavae, Carlino Dianthetum deltoidis). The occurrence of Giant horsetail in such differentiated communities points to its wide ecological scale and the ability to survive in different forms of anthropogenic pressure. The appearance of this species in agricultural land communities may be result of its previous existence on the land that started to be cultivated land or of the vegetative spreading of its rhizomes.

Published: December 2013

Croatia is a country of diverse plant use traditions, which are still insufficiently documented. The aim of this study was to document local traditions of using wild food plants around Lake Vrana (northern Dalmatia, Zadar region). 

We interviewed 43 inhabitants of six traditional villages north of Lake Vrana. On average 12 species were listed, which in total produced an inventory of 55 food plants and 3 fungi taxa. Wild vegetables were most widely collected, particularly by older women who gathered the plants mainly when herding their flocks of sheep. Wild fruits and mushrooms were rarely collected. The former used to be an important supplementary food for children, or for everyone during times of food shortage, and the latter were relatively rare due to the dry climate and shortage of woods.

The most commonly collected plants are wild vegetables: Cichorium intybus, Foeniculum vulgare, Sonchus oleraceus, Asparagus acutifolius, Papaver rhoeas, Rumex pulcher, Daucus carota, Allium ampeloprasum and Silene latifolia.

DOI: 10.5902/198346597166 Recycling is a topic of great importance in integrated waste management, evidence of this is verified in the National Policy of Solid Waste, decreed in 2010, where it is considered one of the priorities. In this article is presented a computer simulation model, since their development until its validation, which aims to support environmental managers in their decisions regarding the definition and / or maintenance of solid waste policies recycling, as well as evaluating the benefits of process in the environment (in this article we evaluated the energy savings). For the model development was considered: the rate of natural population growth (births and deaths), percentage of solid waste recycled (for each type of material), gravimetric composition of the material in the total waste generated, the amount of waste generated per inhabitant and energy savings caused by each distinct type of material. Through the model results generated, end users (environmental managers) thereof may, for example, set incentives to reduce the total generation of solid waste, produce campaigns enhancing reuse and recycling and to assess the relative benefits of energy savings caused by recycling. Model validation was through analysis of future scenarios for a given municipality in southern Brazil. For modeling and system validation was used Vensim from Ventana Systems.

This study was developed in a Federal School Institution in Sao Paulo State – Brazil searching to identify the link developed between Institution administrative support staff members and their social networks. The research objective is to establish a comparison between the link data facts with Social Networks Theories which says that the more ties (contacts) exist in an informal group, the more the network promotes an open environment for exchanging knowledge and information.  The research looked forward to identify how do the social networks are developed, how common objectives and subjects turns people closely connected, how do the focal points and main contacts emerge from this community and what are their influences in the rest of the group. It was applied social network measurement methodologies, combined with qualitative instrument analysis. As a conclusion, was found that the informal structure has influence over the formal structure providing an environment for exchanging knowledge and information, pointing out that some characters are actually responsible for the dynamic of networks, occupying driver and strategic position that gives them recognition as such by the other agents in the net.

The aim of this study was to determine how the strategy is developed in practice for the recognition of an undergraduate degree at MEC. For both: (i) identify the strategic practices adopted in the organization, (ii) verify how the practice happens at different organizational levels and (iii) analyze how practitioners participating in the strategy as practice. The research approach is qualitative. The study was conducted in a private college of character located in northern Paraná. We used a semi-structured interview structured with open questions, document analysis and observation, and data collection techniques, providing triangulation of data collected. For the data analysis we adopted the technique Exam Pattern of Behavior (PÉREZ-AGUIAR, 1999). The results highlight the need for alignment between the three elements developed in the work Jarzabkowski et al. (2007), and emphasize the existence of the axis of environmental management across the entire line as pedagogical courses offered, as a requirement of MEC.

For both, it was found-Environmental Indicators using the Social balance sheet to verify participation in net revenues of the companies surveyed. The methodology was characterized as descriptive, through desk research and quantitative approach. With respect to the results, it was found that companies have positive correlation between net (RL) and the internal social indicators (ISI) and external (ISE), environmental indicators (IA), amount of Employees (QF) and number of employees with special needs (QFNE), and the higher the value of net revenues increased participation in the value of these indicators. In general analysis, it was found that the Environmental Indicators correlate positively with net revenue, so that companies with higher value in net revenues also had the highest values in the searched Indicators.

This study aims to investigate the suitability of volumetric-modulated arc therapy (VMAT) with RapidArc for primary leiomyosarcoma (LMS) in the spine, and present a new method to improve the target coverage and organs at risk (OAR) sparing. Five patients with LMS were retrospectively reviewed. The intensity-modulated radiotherapy (IMRT) with five coplanar beams (5b-IMRT) or seven coplanar beams (7b-IMRT), and VMAT using four quasi-quarter coplanar arcs (4q-VMAT) or two full coplanar arcs (2f-VMAT) were generated. Planning target volume (PTV) dose coverage, OAR dose sparing, conformity index (CI), and homogeneity index (HI) were evaluated. A hollow-cylinder model (HCM) was also used for feasible optimal beam arrangements. The mean doses to PTV were 95.2% ± 1.0%, 93.0% ± 1.0%, 97.9% ± 1.0% and 96.2% ± 1.5% for 4q-VMAT, 2f-VMAT, 5b-IMRT and 7b-IMRT respectively, while the mean maximum doses to spinal cord (SC) were 43.7 ± 0.9 Gy, 42.0 ± 0.8 Gy, 41.4 ± 1.2 Gy and 40.6 ± 1.4 Gy. Compared to 5b-IMRT, the mean doses delivered to kidneys decreased by about 35.1% (8.5 Gy), 2.5% (0.6 Gy) and 35.5% (8.6 Gy) for 4q-VMAT, 2f-VMAT, and 7b-IMRT, respectively. The CI proposed by Baltas et al. was twice as good with IMRT than with 4q-VMAT, and the numbers of monitor units were increased five- and threefold with 7b-IMRT and with 5b-IMRT compared to VMAT. The unexpected results we presented here show that VMAT technique can't achieve highly conformal treatment plans while maintaining SC sparing for LMS in the spine. An approach is proposed based on a hollow-cylinder model, but it is difficult to apply to clinical practice. In this case, VMAT is not superior to IMRT except for significant reduction in delivery time.
Refining the relationship between lightning and convective rainfall over the ocean
Authors: Stolz Douglas C. , Businger Steven , Terpstra Annick
Published: December 2013

The lightning stroke density observed by Vaisala's Global Lightning Dataset (GLD360) was compared to maximum reflectivity in the upper and lower troposphere observed by NASA's Tropical Rainfall Measuring Mission Precipitation Radar over remote oceanic regions. We found that GLD360 stroke density is strongly correlated with maximum reflectivity above 0°C and the height of the 30 dBZ isopleth in two ocean basins (best represented by a logarithmic least squares regression). The maximum reflectivity above 0°C increases ~8–10 dBZ and the maximum height of the 30 dBZ isopleth increases ~2.8–3.8 km across the domain of stroke density. Stroke density and the maximum near‐surface reflectivity are also correlated, but the range of the resulting logarithmic relationship is less than that found for maximum reflectivity above 0°C. There is high confidence in the logarithmic regressions as R2 values are generally above 0.9 during the study. A bootstrap resampling approach confirms that the lightning versus rainfall relationship is statistically significant. Vertical profiles of radar reflectivity show that progressively larger values of stroke density are associated with higher reflectivity at most altitudes (most pronounced near 6.5 km mean sea level) and less rapid decreases in reflectivity with increasing height above 0°C. The logarithmic relationships between lightning and rainfall defined in this study have significant utility in creating proxy data sets, such as pseudoreflectivity, for weather analysis and assimilation in numerical weather prediction.
Paraguay‐Araguaia Belt Conductivity Anomaly: A fundamental tectonic boundary in South American Platform imaged by electromagnetic induction surveys

Published: December 2013

We discovered and mapped a 1200 km‐long zone of enhanced electrical conductivity through a large array of magnetometers, over a narrow corridor parallel to the Paraguay and Araguaia belts which surround the Amazon craton. The anomaly has been further studied using magnetotelluric measurements made along a 300 km profile crossing the Paraguay belt; modeling shows the anomaly at this location as a very strong 100 km‐wide upper‐crust to mid‐crust conductor, located under a region where surficial rocks show an increase in deformation and metamorphism within the belt. From the high conductivity of the anomalous structure, its observed geometry and surface rock exposures, the most likely interpretation of its source is graphitized biogenic material in metasediments, now deeply underthrust in a Neoproterozoic or Early Cambrian suture zone. This result strongly supports the hypothesis that the collision between the Amazon plate and the western Paraná block has probably closed an ocean in the Paraguay belt region, contrary to former propositions of an ensialic evolution for this belt. Although the precise age of this ocean closure have been a matter of debate, our finding significantly constrains the tectonic setting of West Gondwana amalgamation involving the Amazon plate and its surrounding blocks.
Parameterizations of calcic clinopyroxene—Melt trace element partition coefficients
Authors: Bédard Jean H.
Published: December 2013

Semiempirical parameterizations of the values and trends of variation of Nernst trace element partition coefficient data for Ca‐rich clinopyroxene (cpx/liquidD) are provided, applicable mainly to common terrestrial magmatic suites. cpx/liquidD data for most trace elements show significant variability which cannot be neglected when modeling melting and crystallization. The influence of pressure on cpx/liquidD is strong for many elements, particularly Na and Sr, which increase as pressure rises, and most high‐field strength elements, which decrease with increasing pressure. Most cpx/liquidD values increase as temperature decreases, as wt % melt MgO, MgO# (MgO/MgO+FeOtotal), CaO, and FeO contents drop, as cpx molar Mg# (Mg/Mg+Fetotal) decreases, and as wt % melt SiO2 and Na2O+K2O increase. No clear trends are seen for variations of cpx/liquidD against melt H2O. For mafic melts, many elements show well‐defined trends of cpx/liquidD increase as the clinopyroxene tetrahedral Al content (cpx Aliv) increases. Many cpx/liquidD are well correlated against cpx/liquidDTi, and many “near‐neighbor” elements show good cpx/liquidD intercorrelations (e.g., Zr‐Hf, U‐Th, Nb‐Ta, La‐Ce, Yb‐Lu). Cpx/liquidD profiles calculated from these parameterizations can constrain changes of D values during melting or crystallization. Cpx/liquidD for the rare earth elements were fit to the lattice strain model to derive fits that can reproduce the cpx/liquidDREE profile shapes (REE = rare earth elements). These fits indicate that cpx/liquidDREE for melts more evolved than picritic basalts cannot be modeled assuming that all REE are in octahedral coordination in a single M2 site, but also require sixfold partitioning into an M1 site for Lu‐Yb‐Tm‐Er.

Stem cell therapeutics has emerged as a novel regenerative therapy for tissue repair in the last decade. However, dynamically tracking the transplanted stem cells in vivo remains a grand challenge for stem cell‐based regeneration medicine in full understanding the function and the fate of the stem cells. Herein, Ag2S quantum dots (QDs) in the second near‐infrared window (NIR‐II, 1.0–1.4 μm) are employed for dynamically tracking of human mesenchymal stem cells (hMSCs) in vivo with high sensitivity and high spatial and temporal resolution. As few as 1000 Ag2S QDs‐labeled hMSCs are detectable in vivo and their fluorescence intensity can maintain up to 30 days. The in situ translocation and dynamic distribution of transplanted hMSCs in the lung and liver can be monitored up to 14 days with a temporal resolution of 100 ms. The in vivo high‐resolution imaging indicates the heparin‐facilitated translocation of hMSCs from lung to liver as well as the long‐term retention of hMSCs in the liver contribute to the treatment of liver failure. The novel NIR‐II imaging offers a possibility of tracking stem cells in living animals with both high spatial and temporal resolution, and encourages the future clinical applications in imaging‐guided cell therapies.
Time‐series and extended Karhunen–Loève analysis of turbulent drag reduction in polymer solutions

Published: December 2013

Direct numerical simulations and statistical analysis techniques are used to study the drag‐reducing effect of polymer additives on turbulent channel flow in minimal domains. Additionally, a new formulation of Karhunen–Loève decomposition for viscoelastic flows is introduced, allowing the dominant features of the polymer stress fields to be characterized. In minimal channels, there are intervals of “active” and “hibernating” turbulence that display very different structural and energetic characteristics; the present work illustrates how the statistics of these intervals evolve over the entire range of drag reduction (DR) levels. The effect of viscoelasticity on minimal channel turbulence is twofold: first, it strongly suppresses the active turbulent dynamics that predominate in Newtonian flow and second, at sufficiently high Weissenberg number it stabilizes the dynamics of hibernating turbulence, allowing it to predominate in the maximum drag reduction regime. In this regime, the stress fluctuations become delocalized from the wall region, encompassing the entire flow domain. © 2014 American Institute of Chemical Engineers AIChE J, 60: 1460–1475, 2014

Published: December 2013

An efficient regio‐selective aryl CH activation and tandem o‐hydroxylation method for 2‐arylbenzimidazoles has been developed by using a Pd(OAc)2/oxone/Cs2CO3 catalytic system. This reaction was successfully optimized by using various catalysts, oxidants, bases, and solvents to achieve the desired products in good yields. Further, preliminary mechanistic studies were conducted to examine the source of oxygen for this transformation. Gratifyingly, this catalytic system is also suitable for the introduction of various alkoxy groups, and delivered the products in good yields. The synthesized compounds were evaluated for their cytotoxic activity in selected human cancer cell lines. Some of the representative compounds (1 f, 2 f, 3 f and 4 f) have significant IC50 values ranging from 1–10 μM. Structure‐activity relationship studies indicate that in these compounds the ethoxy substituent is probably responsible for the improved activity. In addition, the DNA‐binding potential of these compounds was also investigated by UV/vis, fluorescence, and circular dichroism spectroscopy.
