Full textAbstract:
The study of carbon dioxide gas exchange of leaves of Prunus laurocerasus L., Laurus nobilis L. and Viburnum tinus L. under various environmental conditions was carried out. The greatest resistance to drought and the ability to absorb CO2 under hydrothermal stress was found in Viburnum tinus plants. It was determined that the inhibition of the processes of CO2 absorption with increasing water scarcity begins in the studied species with a decrease in soil moisture to 35% field capacity. Under conditions of soil drought, the amount of CO2 absorbed by Prunus laurocerasus leaves is reduced by 10 times, Laurus nobilis – by 7 times, Viburnum tinus – by 2 times. The positive carbon dioxide gas exchange of Prunus laurocerasus, Laurus nobilis and Viburnum tinus in the hot dry period, when the amount of CO2 absorption exceeds its release during respiration by 1–5.1, 1.5–3.7 and 1.1–6.2 times, respectively, indicates a significant potential these species for optimizing the urban ecosystems of the southern regions of Russia. The developed predictive models allow us to perform a quantitative assessment of the ability of plants to absorb carbon dioxide under various environmental conditions.

Full textAbstract:
The Sabatier reaction could be a key tool for the future of the renewable energy field due to the potential of this reaction to produce either fuels or to stabilize H2 in the form of stable chemicals. For this purpose, a new composite made of ruthenium oxide nanoparticles (NPs) deposited on titanate nanotubes (TiNTs) was tested. Titanate nanotubes are a robust semiconductor with a one-dimensional (1D) morphology that results in a high contact area making this material suitable for photocatalysis. Small ruthenium nanoparticles (1.5 nm) were deposited on TiNTs at different ratios by Na+-to-Ru3+ ion exchanges followed by calcination. These samples were tested varying light power and temperature conditions to study the reaction mechanism during catalysis. Methanation of CO2 catalyzed by Ru/TiNT composite exhibit photonic and thermic contributions, and their ratios vary with temperature and light intensity. The synthesized composite achieved a production rate of 12.4 mmol CH4·gcat−1·h−1 equivalent to 110.7 mmol of CH4·gRu−1·h−1 under 150 mW/cm2 simulated sunlight irradiation at 210 °C. It was found that photo-response derives either from Ru nanoparticle excitation in the visible (VIS) and near-infrared (NIR) region (photothermal and plasmon excitation mechanism) or from TiNT excitation in the ultraviolet (UV) region leading to electron–hole separation and photoinduced electron transfer.

Jens Bjering: “Words, Places, and Other Things We Lost in the War: OnRedactions”The article investigates the use of government redactions in three texts which relate in different ways to the War on Terror: Ex-CIA agent Valerie Plame’s Fair Game, the Senate Select Committee on Intelligence’s Study of the Central Intelligence Agency’s Detention and Interrogation Program, and Mohamedou Ould Slahi’s Guantanamo Diary. While the formal reason for redacting texts is to prevent specific pieces of sensitive information from reaching the public, the article claims—and supports through its readings—that redactions in these cases also are used as literary-narrative strategies with which to frame the reader’s general reading experience and thus his or her overall impression of and opinion about the War on Terror.

The article mainly investigated the effect of modified atmosphere packaging (MAP) on quality characters of sturgeon caviar during storage at 0 °C . MAP tested included MAP1 (100%CO2), MAP2 (70%CO2+30%N2), MAP3 (50%CO2+50%N2), MAP4 (30%CO2+70%N2) and MAP5 (100%N2). In order to let gas mixture interact with caver samples, the caviar directly exposed to modified atmosphere in MAP groups, and the control group (AIR) is prepackaged in tins and maintained in the air. Color properties, biochemical analyses (the volatile basic nitrogen values (TVB-N), the thiobarbituric acid values (TBA )) of sturgeon caviar were recorded before packaging (day 0) and after 1, 3 and 5 months of storage. The results showed that the MAP treatments in the study may delay the protein deterioration to some extend and MAP4 group exposed a little advantage to L*. but MAP treatments didn’t show an positive effects on the a*, b*and TBA.

Abstract Treatments were applied on 13 Jun ‘85 to 10 to 14-inch center-pivot irrigated corn. Plots were 100-ft single rows arranged in a randomized complete block design. Granular materials were applied through 7-inch spreaders held 4 inches above the whorl. Liquids were directed at the base of the plants with a CO2 single-nozzle sprayer calibrated o deliver 45 gal per acre at 30 psi. Following application, all plots were cultivated with an Alloway cultivator (Danish tines and 6-inch shovels). Treatments were evaluated on 17 Jul ‘85 by digging 10 consecutive plants from each plot and rating root system damage on the Iowa 1-6 scale (1 = no damage, 6 = 3 nodes of roots lost).

The aims of this study are the quantitative characterisation of the coat colour in the black variety of the Old Kladruber Horse breed, the estimation of the coat colour genetic parameters, and the determination of the factors that influence coat colour intensity. A total of 252 horses aged 1–24 years were included in the study. The colour parameters were taken using a Konica Minolta spectrophotometer CM-2500d at four different body parts during the summer and winter seasons, resulting in 1748 phenotypic records. The possible effects of sex, season, housing system, age and body part on the spectrophotometric parameters were analysed. The results confirmed that the intensity of the black coat colour can be influenced by a number of factors (sex, season, housing system, and age). The mares showed more red and yellow colour compared to the stallions. In the winter season, the horses had a lighter colour with a lower proportion of reddish-brown hairs. Horses kept outdoors, especially in the summer months, had a lighter colour with a higher proportion of red and yellow. Although the age was statistically significant, no specific trend was observed. The differences in colour found between body parts (neck, shoulder, belly, and croup) are in line with current knowledge – reddish fading in the blacks primarily occurs in the belly region. The estimated heritability values suggest possible multifactorial inheritance, especially with regards to the reddish tinge in hairs (h<sup>2</sup> = 0.20 to 0.29 according to body part).

Abstract Four insecticides were applied at planting time at a site near Coleridge, NE, on 11 May. The soil type was silty clay loam and the previous crop was alfalfa. The field was prepared by killing the alfalfa with 2,4-D, disking once, and using a field finisher before planting. Very little plant residue remained. The experimental design was a randomized complete block with 4 replicates. Each treatment consisted of 2 rows 16 m long, with 2 untreated rows between each treatment; rows were 76.2 cm apart. Granular materials were applied in a 17.8 cm band by a John Deere 2-row planter equipped with a cone-belt insecticide distributer and incorporated by tines. Ambush 2 E was broadcast applied immediately after planting, with a 4-nozzle CO2 back pack sprayer equipped with T-jet 8002 nozzles applying approximately 177 liters/ha total volume at 25 psi. Spray width was 1.66 m. Topsoil moisture was adequate at time of planting and no rain fell during the evaluation period. No phytotoxicity was observed. Plots were evaluated by counting plants remaining on either side of a randomly selected 6.66 m length marked between the two treated rows. Final plant stand count was taken on 6 Jun.

In spring 2013, pot-grown Viburnum tinus plants shipped to an ornamental nursery in Pescia (Pistoia, central Italy, 287 m a.s.l., 43°54′0″ N, 10°41′0″ E) from another local nursery were found to bear disease symptoms. Symptoms included brown to black foliar lesions, later expanding into larger blotches; necrosis of the petioles; shoot wilting and folding; browning of the stems; and necrosis of the cambium. Infected leaves, shoots, and entire plants eventually died. Tissue samples (2 mm2) were cut at the edge of active lesions from tissue of the phloem, the xylem, and the leaves and plated on selective PARPNH V8 agar (V8A) (1). Rose-shaped and finely lobed cottony colonies arose in 2 to 3 days. Mono-hyphal colonies were isolated and transferred to V8A. Square colony pieces (1 cm2) from isolates SB05a and SB05b were placed in filtered pond water after 5 to 7 days. Semipapillate, caducous sporangia with a rounded or conical base were produced within 24 h, individually or in pairs, on each sporangiophore. Sporangia (n = 30 per isolate) were examined: they were 56.2 ± 9.5 × 29.3 ± 4.3 μm (l:b ratio 1.9 ± 0.3). Exit pores averaged 7.0 ± 1.0 μm. Sporangia were ellipsoid (30%), lemon-shaped (28.3%), ovoid (20%), obovoid (16.7%), ampulliform (3.3%), or “peanut-like” (1.7%). Globose chlamydospores, borne intercalarly or terminally, were abundant on both V8A and carrot agar (CA), and were on average 54.7 ± 8.5 μm. Mono-hyphal isolates incubated for 7 days at 23°C were also transferred to CA, corn meal agar (CMA), malt extract agar (MEA), potato dextrose agar (PDA), and V8A. Colonies on these media were identical in shape and appearance to those described in previous reports (2,4). Isolates were identified as Phytophthora ramorum Werres, De Cock & Man in't Veld (4) on the basis of colony type; size, the average l:b ratio and shape of sporangia; and the type and size of the chlamydospores. Isolates were found to be the A1 mating type by pairing them with P. cryptogea BBA 63651 (mating type A2). PCR-amplification of the rDNA ITS region with specific primers Ph1/Ph4 (3) gave fragments of the expected size (GenBank Accession Nos. KF181162 and KF181163). A BLAST search of these ITS sequences in the database found that isolates of P. ramorum were the closest phylogenetically with 100% homology (YQ653034 and HM004221). Pathogenicity tests were conducted on 16 detached V. tinus leaves. A small cut was made aseptically on each of the leaf surfaces and a V8A disc (0.5 cm Ø) with mycelium was placed over the wounds. Control leaves received only sterile V8A discs. Inoculated and control leaves were incubated at 23°C in the dark. Necrotic areas (average 3.5 ± 1.3 cm2) arose on inoculated leaves after 6 days. Control leaves had no symptoms. Re-isolations on PARPNH V8A confirmed P. ramorum as the causal agent. P. ramorum was reported in Italy in 2003 on the exotic Rhododendron yakushimanum (2). This is the first report of the pathogen on a native species (V. tinus) in this country. The Pistoia area is important for nursery gardens and flowers. P. ramorum, which probably arrived on infected plant material, could compromise the export/import trade in stock plants. For this reason, the plant protection services were promptly alerted and the infected plants were destroyed. References: (1) Y. Balci et al. Plant Dis. 91:705, 2007. (2) C. Gullino et al. Inf.

Abstract Granular and liquid insecticides were applied at planting time (P) and post plant at Concord, NE. The test plot was planted 8 May in a continuous corn field with a silty clay loam type. The experimental design was a randomized complete block with 4 replicates. Each treatment consisted of a single 16 m long row; rows were 75 cm apart. Granular materials were applied infurrow or in an 18 cm band with a John Deere 2 row planter equipped with a cone-belt insecticide distributor and incorporation tines. Cultivation treatments (C) were applied over the row on 12 Jun with a cone-belt distributor mounted on a hand powered bicycle wheel applicator. Cultivation application was followed immediately by a tractor mounted cultivator after all treatments were applied. Furadan 4 F was applied over the row at 2 different rates and 2 different times (21 May, E, and 3 Jun, L) in a 37 cm band, with a CO2 backpack sprayer at 25 psi, approximately 142 liters/ha total volume. No phytotoxicity was observed. Stand counts were not significantly different. Feeding damage was evaluated 20 and 21 Jul. Five roots were dug from each treatment row and rated by the Iowa 1-6 scale (1, no damage; 6, 3 or more nodes of toots completely destroyed).

AbstractPalladosilicide, Pd2Si, is a new mineral (IMA 2014-080) discovered in chromite-rich samples from the Kapalagulu intrusion, western Tanzania (30°03′51′′E 5°53′16′′S and 30°05′37′′E 5°54′26′′S) and from the UG-2 chromitite, Bushveld complex, South Africa. A total of 13 grains of palladosilicide, ranging in size from 0.7 to 39.1 μm (equivalent circle diameters), were found. Synthetic Pd2Si is hexagonal, space group P62m, with a = 6.496(5), c = 3.433(4) Å, V = 125.5(1) Å3, c:a = 0.529 with Z = 3. The strongest lines calculated from the powder pattern (Anderko and Schubert, 1953) are [d in Å (I) (hkl)] 2.3658 100 (111); 2.1263 37 (120); 2.1808 34 (021); 3.240 20 (110); 1.8752 19 (030); 1.7265 12 (002); 1.3403 11 (122); 1.2089 10 (231). The calculated density for three analyses varies from 9.562 to 9.753 g cm–3. Palladosilicide is considered to be equivalent to synthetic Pd2Si based on results from electron backscattered diffraction analyses. Reflectance data in air for the four Commission on Ore Mineralogy wavelengths are [λ nm, R1 (%) R2 (%)] 470 49.6 52.7; 546 51.2 53.8; 589 51.6 53.7; 650 51.7 53.3 and the mineral is bright creamy white against chromite, weakly bireflectant and displays no discernible pleochroism or twinning. It is weakly anisotropic, has weak extinction and rotation tints in shades of blue and olive green. Electron probe microanalyses of palladosilicide yield a simplified formula of Pd2Si.

Full textAbstract:
The H+-K+-ATPase α-subunit (HKα2) participates importantly in systemic acid-base homeostasis and defends against metabolic acidosis. We have previously shown that HKα2 plasma membrane expression is regulated by PKA (Codina J, Liu J, Bleyer AJ, Penn RB, DuBose TD Jr. J Am Soc Nephrol 17: 1833–1840, 2006) and in a separate study demonstrated that genetic ablation of the proton-sensing Gs-coupled receptor GPR4 results in spontaneous metabolic acidosis (Sun X, Yang LV, Tiegs BC, Arend LJ, McGraw DW, Penn RB, Petrovic S. J Am Soc Nephrol 21: 1745–1755, 2010). In the present study, we investigated the ability of chronic acidosis and GPR4 to regulate HKα2 expression in HEK-293 cells. Chronic acidosis was modeled in vitro by using multiple methods: reducing media pH by adjusting bicarbonate concentration, adding HCl, or by increasing the ambient concentration of CO2. PKA activity and HKα2 protein were monitored by immunoblot analysis, and HKα2 mRNA, by real-time PCR. Chronic acidosis did not alter the expression of HKα2 mRNA; however, PKA activity and HKα2 protein abundance increased when media pH decreased from 7.4 to 6.8. Furthermore, this increase was independent of the method used to create chronic acidosis. Heterologous expression of GPR4 was sufficient to increase both basal and acid-stimulated PKA activity and similarly increase basal and acid-stimulated HKα2 expression. Collectively, these results suggest that chronic acidosis and GPR4 increase HKα2 protein by increasing PKA activity without altering HKα2 mRNA abundance, implicating a regulatory role of pH-activated GPR4 in homeostatic regulation of HKα2 and acid-base balance.

The experimental design was a randomized complete block with 4 replicates. Each treatment consisted of 2 rows 16 m long, with 2 untreated rows between each treatment; rows were 75 cm apart. Granular materials were applied in an 18 cm band by a John Deere 2 row planter equipped with a cone-belt insecticide distributor and incorporated by tines. Ambush 2 E was broadcast immediately after planting, with a 4 nozzle CO2 back pack sprayer equipped with T-jet 8002 nozzles applying approximately 177 liters/ha total volume at 25 psi. Spray width was 1.66 m. Ambush 2E was also banded with the same spray equipment but the 4 nozzle boom was replaced with a single nozzle. Band width was 37.7 cm. Topsoil moisture was adequate at time of planting and no rain fell during the evaluation period. Plots were evaluated by counting plants remaining on either side of a randomly selected 10 m length marked between the 2 treated rows. The results are given as number of plants per 20 m of row.

Verongiid sponges inhabiting the La Paz region, Gulf of California are described herein as new species. Although morphological evidence was sufficient to determine the identity between species, we have confirmed their uniqueness and relationships with molecular (CO1 and ITS1 and 2), and ecological studies. An amended definition of family Aplysinidae and genus Aplysina is presented to highlight a novel skeletal trait for the latter, clearly described herein as a complex of dendritic fibers sustained by anastomosed fibers deep in the choanosome. This novel fiber arrangement combination is a constant trait of Aplysina encarnacionae sp. nov. and A. airapii sp. nov., which otherwise conform to our current concept of Aplysina. The former species has a long tubular morphology, reddish purple color, with the longest dendritic fibers; while A. airapii sp. nov. is a short tubular sponge, yellow with reddish tints, and smaller choanosomal dendritic fibers that depart from a uniplanar anastomosed skeleton. A third species, A. sinuscaliforniensis sp. nov., is characterized by a completely anastomosed skeleton, massive habit with short tubes superimposed one over the other, sympatric with the other new species. Comparisons with Suberea azteca verified that the same novel skeletal architecture described here occurs in the latter, while Aiolochroia thiona examined as well, proved to bear an anastomosed skeleton only, besides sharing more features with Aplysina than with any other genera in Verongiida. Moreover, molecular sequencing recovered “S.” azteca nested in the Aplysina clade, prompting us to reallocate it in Aplysina, as originally proposed. The new species described herein are probably endemics within the Gulf of California since they have not been recorded elsewhere along the Mexican Pacific coast.

We previously reported that the deletion of the pH sensor GPR4 causes a non-gap metabolic acidosis and defective net acid excretion (NAE) in the GPR4 knockout mouse (GPR4−/−) (Sun X, Yang LV, Tiegs BC, Arend LJ, McGraw DW, Penn RB, and Petrovic S. J Am Soc Nephrol 21: 1745–1755, 2010). Since the major regulatory site of NAE in the kidney is the collecting duct (CD), we examined acid-base transport proteins in intercalated cells (ICs) of the CD and found comparable mRNA expression of kidney anion exchanger 1 (kAE1), pendrin, and the a4 subunit of H+-ATPase in GPR4−/− vs. +/+. However, NH4Cl loading elicited adaptive doubling of AE1 mRNA in GPR4+/+, but a 50% less pronounced response in GPR4−/−. In GPR4+/+, NH4Cl loading evoked a cellular response characterized by an increase in AE1-labeled and a decrease in pendrin-labeled ICs similar to what was reported in rabbits and rats. This response did not occur in GPR4−/−. Microperfusion experiments demonstrated that the activity of the basolateral Cl−/HCO3− exchanger, kAE1, in CDs isolated from GPR4−/− failed to increase with NH4Cl loading, in contrast to the increase observed in GPR4+/+. Therefore, the deficiency of GPR4 blunted, but did not eliminate the adaptive response to an acid load, suggesting a compensatory response from other pH/CO2/bicarbonate sensors. Indeed, the expression of the calcium-sensing receptor (CaSR) was nearly doubled in GPR4−/− kidneys, in the absence of apparent disturbances of Ca2+ homeostasis. In summary, the expression and activity of the key transport proteins in GPR4−/− mice are consistent with spontaneous metabolic acidosis, but the adaptive response to a superimposed exogenous acid load is blunted and might be partially compensated for by CaSR.

Proses pemadatan dengan vibrasi untuk mendapatkan beton yang berkualitas memiliki kesulitan ketika diperhadapkan dengan model struktur yang kompleks. Sehingga beberapa dekade terakhir telah dilakukan penelitian dan pengembangan beton yang bisa memadat sendiri, yang dikenal dengan nama self-compacting concrete (SCC). Pengaplikasian SCC di Indonesia masih terbatas karena biaya pembuatannya yang cukup tinggi. Komposisi semen pada beton SCC lebih banyak dari beton konvensional yang artinya menimbulkan polusi udara lebih tinggi. Jumlah produksi semen berbanding lurus dengan jumlah CO2 yang dilepas ke atmosfer, maka industri semen dunia memberikan kontribusi besar terhadap emisi gas rumah kaca global. Beberapa penelitian mulai berinovasi mengkombinasikan SCC dan teknologi penggantian semen secara keseluruhan dengan material pozzolan yang memiliki karakteristik seperti semen. Salah satu alternatif material pengganti semen portland adalah fly ash yang merupakan material buangan pembakaran batu bara di PLTU. Agar Fly ash bisa mengikat seperti semen diperlukan aktivator. Campuran fly ash dan aktivator dikenal sebagai semen geopolimer, sehingga kombinasi dua teknologi beton ini disebut beton self compacting geopolymer dengan material dasar fly ash. Di Indonesia, beton self compacting geopolymer masih terbatas dalam tahap pengujian mix design, sehingga penulis tertarik mengetahui tinjauan ekonomis beton jenis ini, dan bermaksud menganalisa biaya pembuatan beton self compacting geopolymer ini menggunakan material lokal, fly ash dari PLTU II Amurang, Sulawesi Utara. Penelitian dimulai dengan pemeriksaan material lokal di Sulawesi Utara untuk mencari mix-design beton. Dilanjutkan dengan melakukan pengujian experimental untuk mendapatkan karakteristik kelecakan beton segar dan kuat tekan beton. Selanjutnya dilakukan analisis biaya produksi berdasarkan mix-design per 1 m3 beton. Pengujian kelecakan dari pasta Beton Self Compacting Geopolymer dengan material dasar fly ash melalui metode slump flow,V-funnel test dan L-Box Shaped test menunjukkan bahwa sudah memenuhi syarat SCC juga menghasilkan beton mutu K-250. Beton geopolimer dikombinasikan dengan beton SCC yang biayanya memang sudah relatif tingi menghasilkan biaya pembuatan yang juga tinggi.

AbstractKudryavtsevaite, ideally Na3MgFe3+Ti4O12, is a new mineral from kimberlitic rocks of the Orapa area, Botswana. It occurs as rare prismatic crystals, up to 100 μm m across, associated with Mg-rich ilmenite, freudenbergite and ulvöspinel. Kudryavtsevaite is opaque with a vitreous lustre and shows a black streak. It is brittle; the Vickers hardness (VHN100) is 901 kg mm−2 (range: 876–925) (Mohs hardness ∼6). In reflected light, kudryavtsevaite is moderately bireflectant and very weakly pleochroic from dark grey to a slightly bluish grey. Under crossed polars, it is very weakly anisotropic with greyish-bluish rotation tints. Internal reflections are absent. Reflectance values (%), Rmin and Rmax, are: 21.3, 25.4 (471.1 nm), 20.6, 24.1 (548.3 nm), 20.0, 23.5 (586.6 nm) and 19.1, 22.4 (652.3 nm).Kudryavtsevaite is orthorhombic, space group Pnma, with a = 27.714(1), b = 2.9881(3), c = 11.3564(6) Å, V = 940.5(1) Å3, and Z = 4. The crystal structure [R1 = 0.0168 for 819 reflections with I > 2σ(I)] consists of edge-sharing and corner-sharing chains composed of Mg, Fe3+ and Ti atoms coordinated by six atoms of oxygen and running along the b axis, with Na filling the tunnels formed by the chains. The eight strongest powder-diffraction lines [d in Å (I/I0) (hkl)] are: 7.17 (100) (301), 4.84 (70) (302), 2.973 (35) (901), 2.841 (50) (004), 2.706 (50) (902), 2.541 (50) (312), 2.450 (70) (611), and 2.296 (45) (612). The average results of 12 electron microprobe analyses gave (wt.%): Na2O 16.46(15), CaO 1.01(3), MgO 5.31(5), Fe2O3 22.24(32), Cr2O3 1.05(6), Al2O3 0.03(2), TiO2 53.81(50), total 99.91, corresponding to the empirical formula (Na2.89Ca0.10)Σ2.99(Ti3.67Fe1.523+Mg0.72Cr0.08)Σ5.99O12, or ideally Na3MgFe3+Ti4O12.The new mineral has been approved by the IMA-CNMNC and named for Galina Kudryavtseva (1947–2006), a well known Russian mineralogist and founder of the Diamond Mineralogy Laboratory and scientific school for investigation of diamond mineralogy and geochemistry at the Lomonosov State University in Moscow, Russia.

AbstractThe new mineral hrabákite (IMA2020-034) was found in siderite–sphalerite gangue with minor dolomite–ankerite at the dump of shaft No. 9, one of the mines in the abandoned Příbram uranium and base-metal district, central Bohemia, Czech Republic. Hrabákite is associated with Pb-rich tučekite, Hg-rich silver, stephanite, nickeline, millerite, gersdorffite, sphalerite and galena. The new mineral occurs as rare prismatic crystals up to 120 μm in size and allotriomorphic grains. Hrabákite is grey with a brownish tint. Mohs hardness is ca. 5–6; the calculated density is 6.37 g.cm–3. In reflected light, hrabákite is grey with a brown hue. Bireflectance is weak and pleochroism was not observed. Anisotropy under crossed polars is very weak (brownish tints) to absent. Internal reflections were not observed. Reflectance values of hrabákite in air (Rmin–Rmax, %) are: 39.6–42.5 at 470 nm, 45.0–47.5 at 546 nm, 46.9–49.2 at 589 nm and 48.9–51.2 at 650 nm). The empirical formula for hrabákite, based on electron-microprobe analyses (n = 11), is (Ni8.91Co0.09Fe0.03)9.03(Pb0.94Hg0.04)0.98(Sb0.91As0.08)0.99S7.99. The ideal formula is Ni9PbSbS8, which requires Ni 47.44, Pb 18.60, Sb 10.93 and S 23.03, total of 100.00 wt.%. Hrabákite is tetragonal, P4/mmm, a = 7.3085(4), c = 5.3969(3) Å, with V = 288.27(3) Å3 and Z = 1. The strongest reflections of the calculated powder X-ray diffraction pattern [d, Å (I)(hkl)] are: 3.6543(57)(200); 3.2685(68)(210); 2.7957(100)(211); 2.3920(87)(112); 2.3112(78)(310); 1.8663(74)(222); and 1.8083(71)(302). According to the single-crystal X-ray diffraction data (Rint = 0.0218), the unit cell of hrabákite is undoubtedly similar to the cell reported for tučekite. The structure contains four metal cation sites, two Sb (Sb1 dominated by Pb2+) and two Ni (with minor Co2+ content) sites. The close similarity in metrics between hrabákite and tučekite is due to similar bond lengths of Pb–S and Sb–S pairs. Hrabákite is named after Josef Hrabák, the former professor of the Příbram Mining College.

Abstract Corn was planted in 30-inch rows with a John Deere 7000 series 4-row planter on 26 Apr in a fall-plowed, spring-disked field at Champaign and on May 8 in a spring-disked (2x) field at Bloomington. Pioneer 3540 and Funks G-4326 hybrid seed corn was planted at Champaign and Bloomington, respectively. Granular insecticides were applied with Noble units mounted on each of the planter units. The granular insecticides were applied in a 7-inch band in front of the firming wheels, applied in a 7-inch band behind the firming wheels, or applied in the seed furrow. Dyfonate 15G and 20G were purposely applied in front of the firming wheels to see if phototoxicity would result. The granules in the banded treatments were incorporated with spring tines mounted behind the firming wheels. Dyfonate 4.6MS was applied in a 7-inch band over the row immediately following planting with a CO2 sprayer equipped with a single nozzle wand (Spraying Systems no. 8002E even flat fan nozzle, 3.0 ft/sec 20 psi, 10 gal water/acre based on a row width of 40 inches). Dyfonate 4.6MS and Dyfonate 4E cultivator treatments were applied in a 7-inch band over the row when corn was in the 3-leaf stage on May 28 (same spray system as above). All sprays were incorporated into the soil with a hand cultivator immediately after application. Each insecticide treatment consisted of a single 60-foot row arranged in a randomized complete block (Champaign) or a completely randomized (Bloomington) design with 4 replications per treatment. Root systems were evaluated for rootworm damage in mid-Jul by digging and washing 20 plants from each treatment (5 roots per row by 4 reps) and examining the roots for rootworm feeding damage. The standard Iowa 1 to 6 damage rating scale (1, little or no damage and 6, three or more nodes of roots destroyed) was used to measure damage.

Abstract Each plot consisted of four rows by 40 feet long, with treatments applied tc the center two rows, leaving two untreated rows between each plot. A RCB design with four replications was used. Two untreated check plots were includec in each replication and were averaged for ANOVA. Fifteen third- to fourth-instar laboratory reared BCW larvae were placed in each barrier arena on 2’. May. Corn plants within each barrier were in the Vl-2 stage (Iowa State Special Report, No. 48), at the time of larval release. The larvae used in this tes were supplied by Dr. Armon Keaster and Mary Jackson of the University of Missouri. Pre-plant insecticide treatments were applied with a CO2 back-pack sprayer utilizing four 8003VS nozzles calibrated to deliver 18.7 gpa at 25 psi, broadcast over what would become the center two rows of the four-row plots Planting-time granular insecticides were metered through Noble units mounted on each of the center 2 planter units. These granules were applied in a 7-incl band ahead of the firming wheels on the planter. Spring tines mounted behind each planter unit were used to incorporate insecticides into the soil. Planting time microtube liquid treatments of (Regent 4SC 0.13 lb(AI)/acre and Regent 4SC 0.13 lb(AI)/acre + Pounce 3.2 EC 0.05 lb(AI)/acre) were applied usinj microtubes directed into the furrow and calibrated to deliver 1.0 gpa at 20 psi. Planting-time banded liquid treatments of (Regent 4 SC 0.13 lb (AI)/acre anc Regent 4 SC 0.13 lb (AI)/acre + Pounce 3.2 EC 0.05 lb (AI)/acre) were applied with two 80067 TeeJet nozzles (1 per row), in a 7-inch band, with a compressed-air system calibrated to deliver 3.3 gap at 16 psi and a speed of 2.5 mph. Pre-emergence insecticide treatments were applied with a CO, back-pack sprayer utilizing 4 8003VS nozzles calibrated to deliver 18.7 gpa at 25 psi, over the center two rows of the four-row plots. Rescue insecticide treatment; were applied utilizing the same equipment used for the pre-emergence treatments over the center two rows of the four-row plots.

Full textAbstract:
Tamuraite, ideally Ir5Fe10S16, occurs as discrete phases (≤20 μm) in composite inclusions hosted by grains of osmium (≤0.5 mm across) rich in Ir, in association with other platinum-group minerals in the River Ko deposit of the Sisim Placer Zone, southern Krasnoyarskiy Kray, Russia. In droplet-like inclusions, tamuraite is typically intergrown with Rh-rich pentlandite and Ir-bearing members of the laurite–erlichmanite series (up to ~20 mol.% “IrS2”). Tamuraite is gray to brownish gray in reflected light. It is opaque, with a metallic luster. Its bireflectance is very weak to absent. It is nonpleochroic to slightly pleochroic (grayish to light brown tints). It appears to be very weakly anisotropic. The calculated density is 6.30 g·cm−3. The results of six WDS analyses are Ir 29.30 (27.75–30.68), Rh 9.57 (8.46–10.71), Pt 1.85 (1.43–2.10), Ru 0.05 (0.02–0.07), Os 0.06 (0.03–0.13), Fe 13.09 (12.38–13.74), Ni 12.18 (11.78–13.12), Cu 6.30 (6.06–6.56), Co 0.06 (0.04–0.07), S 27.23 (26.14–27.89), for a total of 99.69 wt %. This composition corresponds to (Ir2.87Rh1.75Pt0.18Ru0.01Os0.01)Σ4.82(Fe4.41Ni3.90Cu1.87Co0.02)Σ10.20S15.98, calculated based on a total of 31 atoms per formula unit. The general formula is (Ir,Rh)5(Fe,Ni,Cu)10S16. Results of synchrotron micro-Laue diffraction studies indicate that tamuraite is trigonal. Its probable space group is R3m (#166), and the unit-cell parameters are a = 7.073(1) Å, c = 34.277(8) Å, V = 1485(1) Å3, and Z = 3. The c:a ratio is 4.8462. The strongest eight peaks in the X-ray diffraction pattern [d in Å(hkl)(I)] are: 3.0106(216)(100), 1.7699(420)(71), 1.7583(2016)(65), 2.7994(205)(56), 2.9963(1010)(50), 5.7740(102)(45), 3.0534(201)(43) and 2.4948(208)(38). The crystal structure is derivative of pentlandite and related to that of oberthürite and torryweiserite. Tamuraite crystallized from a residual melt enriched in S, Fe, Ni, Cu, and Rh; these elements were incompatible in the Os–Ir alloy that nucleated in lode zones of chromitites in the Lysanskiy layered complex, Eastern Sayans, Russia. The name honors Nobumichi Tamura, senior scientist at the Advanced Light Source of the Lawrence Berkeley National Laboratory, Berkeley, California.

Ferrotorryweiserite, Rh5Fe10S16, occurs as small grains (≤20 µm) among droplet-like inclusions (up to 50 μm in diameter) of platinum-group minerals (PGM), in association with oberthürite or Rh-bearing pentlandite, laurite, and a Pt-Pd-Fe alloy (likely isoferroplatinum and Fe-Pd-enriched platinum), hosted by placer grains of Os-Ir alloy (≤0.5 mm) in the River Ko deposit. The latter is a part of the Sisim placer zone, which is likely derived from ultramafic units of the Lysanskiy layered complex, southern Krasnoyarskiy kray, Russia. The mineral is opaque, gray to brownish gray in reflected light, very weakly bireflectant, not pleochroic to weakly pleochroic (grayish to light brown tints), and weakly anisotropic. The calculated density is 5.93 g·cm–3. Mean results (and ranges) of four WDS analyses are: Ir 18.68 (15.55–21.96), Rh 18.34 (16.32–20.32), Pt 0.64 (0.19–1.14), Ru 0.03 (0.00–0.13), Os 0.07 (0.02–0.17), Fe 14.14 (13.63–14.64), Ni 13.63 (12.58–14.66), Cu 4.97 (3.42–6.41), Co 0.09 (0.07–0.11), S 29.06 (28.48–29.44), and total 99.66 wt.%. They correspond to the following formula calculated for a total of 31 atoms per formula unit: (Rh3.16Ir1.72Pt0.06Ru0.01Os0.01)Σ4.95(Fe4.48Ni4.11Cu1.38Co0.03)Σ10.00S16.05. The results of synchrotron micro-Laue diffraction studies indicate that ferrotorryweiserite is trigonal; its probable space group is R3¯m (#166) based on its Ni-analog, torryweiserite. The unit-cell parameters refined from 177 reflections are a = 7.069 (2) Å, c = 34.286 (11) Å, V = 1484 (1) Å3, and Z = 3. The c:a ratio is 4.8502. The strongest eight peaks in the X-ray diffraction pattern derived from results of micro-Laue diffraction study [d in Å(hkil)(I)] are 2.7950 (202¯5) (100); 5.7143 (0006) (60); 1.7671 (224¯0) (44.4); 3.0486 (202¯1) (39.4); 5.7650 (101¯2) (38.6); 2.5956 (202¯7) (37.8); 3.0058 (112¯6) (36.5); and 1.5029 (42¯ 2¯12) (35.3). Ferrotorryweiserite and the associated PGM crystallized from microvolumes of residual melt at late stages of crystallization of grains of Os- and Ir-dominant alloys occurred in lode zones of chromitites of the Lysanskiy layered complex. In a particular case, the residual melt is disposed peripherally around a core containing a disequilibrium association of magnesian olivine (Fo72.9–75.6) and albite (Ab81.6–86.4), with the development of skeletal crystals of titaniferous augite: Wo40.8–43.2En26.5–29.3Fs20.3–22.6Aeg6.9–9.5 (2.82–3.12 wt.% TiO2). Ferrotorryweiserite represents the Fe-dominant analog of torryweiserite. We also report occurrences of ferrotorryweiserite in the Marathon deposit, Coldwell Complex, Ontario, Canada, and infer the existence of the torryweiserite–ferrotorryweiserite solid solution in other deposits and complexes.

Abstract Background: HER2-targeted agents combined with endocrine therapy (ET) has been recommended as an optional therapeutic strategy for hormone receptor (HR)/human epidermal growth factor receptor 2 (HER2) co-positive metastatic breast cancer (MBC). Pyrotinib is an oral irreversible pan-ErbB receptor tyrosine kinase inhibitor targeting EGFR, HER2 and HER4, with proven efficacy in combination with chemotherapy in HER2-positive MBC. This multicenter, single-arm phase 2 trial aimed to investigate the efficacy and safety of pyrotinib plus letrozole in patients with estrogen receptor (ER)-positive, HER2-positive MBC (NCT04407988). Methods: Pre-/perimenopausal or postmenopausal women with histologically confirmed HER2-positive (immunohistochemistry [IHC] 3+ or 2+ with fluorescence in situ hybridization positive) and ER-positive (the percentage of ER+ cells ≥ 10% by IHC) MBC were enrolled. Prior treatment for metastatic disease was not allowed. Eligible patients received pyrotinib (400 mg, po, qd) plus letrozole (2.5 mg, po, qd) until disease progression or unacceptable toxicity. For pre-/perimenopausal patients, additional treatment with ovarian function suppression (OFS) was required. The primary endpoint was clinical benefit rate (CBR), defined as the rate of patients with complete response (CR), partial response (PR), or stable disease (SD) for at least 24 weeks per RECIST 1.1. Secondary endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety. Results: Between December 3, 2019 and April 2, 2021, 26 patients were enrolled. As of July 5, 2021, CBR was 76.9% (20 of 26; 95% CI 56.4% to 91.0%) and ORR was 57.7% (15 of 26; 95% CI 36.9% to 76.6%). One of the 26 patients (3.8%) had CR, 14 (53.8%) had PR, 5 (19.2%) had SD, 5 (19.2%) had progressive disease, and 1 (3.8%) had not evaluable disease. The benefits in CBR and ORR were observed across all subgroups. The most common any grade AEs were diarrhea (25 of 26, 96.2%), vomiting (8 of 26, 30.8%), nausea (6 of 26, 23.1%), and oral ulceration (6 of 26, 23.1%). Diarrhea was the only reported grade 3 AE that occurred in 5 patients (19.2%). No grade 4 or 5 AEs occurred during this study. Conclusions: Pyrotinib combined with letrozole showed an encouraging antitumor activity with good tolerance in patients with ER/HER2 co-positive MBC, promising as an alternative treatment option for this disease. The study is ongoing.

The Aleppo pine (Pinus halepensis Mill.) is a conifer native to the Mediterranean region. In autumn and spring of 2008 to 2009, a survey of Aleppo pine seedling diseases was carried out in three forest nurseries from the Relizane, Sidi Bel Abbes, and Tlemcen departments in northwestern Algeria. Aleppo pine seedlings were potted from the soil. In all three nurseries, 1- to 2-month old seedlings showed symptoms of damping-off disease in pre- and post-emergence (collar rot) with a disease incidence of 64, 77, and 72%, respectively. Disinfected collar segments, about 5 mm in length, were plated on PDA and petri dishes incubated at 25°C. A Fusarium sp. was consistently isolated from tissues and all isolates were morphologically identified as Fusarium acuminatum Ellis & Everh. (teleomorph: Gibberella acuminata Wollenw.) according to Fusarium keys (2). Colony growth was 43 mm after 3 days on PDA; the aerial mycelium was white, developing a brownish tinge in the center on PDA; macroconidia were formed in orange sporodochia, broadly falcate, strongly septate, 3 to 5 septa, the apical cell with an incurved elongation, distinct foot shape, 3 to 4 × 20 to 50 μm; microconidia were usually absent for isolates other than F12SS1, reniform, septate, 5 to 6 × 6 to 10 μm, in monophialides; chlamydospores were formed in chains, 6 to 13 μm. For the molecular identification, ITS regions of Fusarium isolates were amplified with the primers ITS1 and ITS4, and products were directly sequenced in both strands using the same primers ITS 1 and ITS4. Sequences were compared to known sequences deposited in the NCBI non redundant database to confirm morphological identification. An NCBI BLAST search identified isolates F12SS1, F14SS3, F30SS3, and F25SR as F. acuminatum based on 100% similarity with corresponding sequences. GenBank Accession Nos. were JX114788, JX114785, JX114782, and JX114790, respectively. Pathogenicity tests were performed to fulfill Koch's postulates. Inocula were produced by adding a 5-mm diameter plug from a 7-day-old CMA petri dish culture to a previously sterilized 500-ml flask (237.5 g sand, 12.5 g cornmeal, 80 ml SDW), shaken over 9 days, and mixed with sterile soil at 1:3 (v:v). The inocula were transferred to a 500-ml pot, and 10 Aleppo pine seeds were planted with three replicates. After 1 month, all tested isolates caused typical symptoms on seedlings and the proportion of infected seedlings per each isolate was 50, 53.33, 56.66, 60, and 63.33%, respectively. There are many reports of F. acuminatum associated to conifer seedlings in nurseries (1,3) and most of them are conflicting because in some reports this species is considered non-pathogenic or only a seed contaminant and others consider it as a pathogen. To our knowledge, F. acuminatum is a first report on the Aleppo pine in northwestern Algeria, northern Africa. It is also the first report of this fungal species affecting the Aleppo pine throughout the world, and on conifers in Africa and the Mediterranean region. References: (1) D. F. Farr and A. Y.

Full textAbstract:
Abstract Phalaenopsis orchids are recognized as the most popular orchid genus in the world, especially in horticultural industry due to their large, colorful, and durable flowers as well as their wider adaptability to room conditions. The characteristics of seedling propagated by vegetative means are not uniform; therefore, propagation through tissue culture is desirable. Although the micro propagation of Phalaenopsis has shown very good development, but the wide spread of micro propagation still limited due some problems such as the exudation of phenolic compounds, the PGR concentration, the media used, somaclonal variation, the chosen explants, etc. This paper endeavor to include some important investigations based on the common explants used; leaf and flower stalk.

Full textAbstract:
The alkali volcanics and intrusive rocks, dated at around 35-33Ma, are cut by mineralised northeast and east trending faults showing predominant evidence for strike-slip. Mineralisation includes haematite-Au-Cu and is accompanied by iron-rich alteration of the volcanic rocks. Detailed assessment of the geometry of the fault system at Pu Sam Cap suggests that the faults formed as a Riedel shear system during left-lateral slip within the Song Hong-Song Chay shear zone and the numerous contemporaneous northwest trending faults to the south; the northeast trending faults are interpreted as dextral “book-end’’ faults between major northwest trending faults enclosing the Pu Sam Cap massif. As mineralisation is hosted within these faults and is also associated with lamprohyric dykes it confirms a thermal event younger than the alkaline volcanics and syenitic intrusives at Pu Sam Cap, suggesting a hidden, young porphyry system. The age of faulting, and thus the maximum age for this young intrusive event, is attributed to the 23-21Ma period of late-stage left-lateral strike-slip motion across northwest Vietnam.ReferencesAnczkiewicz R., Viola G., Muntener O., Thrirlwall M., Quong N.Q., 2007.

Full textAbstract:
Three independent experiments assessed CO2 assimilation and metals leaf deposition of seven evergreen shrub species (Arbutus unedo L., Elaeagnus × ebbingei L., Laurus nobilis L., Ligustrum japonicum Thunb., Photinia × fraseri Dress., Viburnum tinus subsp. lucidum L., and Viburnum tinus subsp. tinus L.). CO2 assimilation and carbon allocation were determined in 2011 (Exp. 1) under optimal water availability and in 2012 (Exp. 2) under drought on potted plants. A third experiment (Exp. 3) measured seasonal leaf depositions of Cd, Cu, Ni, Pb, and Zn in 2011 on plants transplanted in proximity of a four-lane road. E. × ebbingei showed the highest CO2 assimilation under optimal water availability but one of the lowest under drought (Exp. 1, 2). Conversely, P. × fraseri had intermediate CO2 assimilation but it declined less during drought compared to the other species. In Experiment 3, E. × ebbingei showed the highest metal deposition, mainly due to its greater leaf area. Greater rainfall and RH% decreased metal depositions, whilst greater wind velocity and air temperature increased leaf depositions. Species which drastically reduce CO2 assimilation under drought (V. tinus subsp. lucidum, L. japonicum, E. × ebbingei) are not recommended in droughtprone environments, where drought-tolerant “mesic” species (P. × fraseri), should be preferred. E. × ebbingei could be used to optimize deposition of metals. The three experiments provide useful insights especially about CO2 assimilation (Exp. 1, 2) and air pollution mitigation (Exp. 3) of widely used shrubs for application in urban areas and planning of roadside greening in southern Europe.
