THE INFLUENCE OF TECHNOLOGICAL ELEMENTS ON THE WINTER TRITICALE YIELD

The paper presents the 4-year data on the behaviour of local winter triticale varieties Ingen 35 and Ingen 93 in multifactorial field experiments. The highest yields of winter triticale varieties were recorded after the forerunner grain peas: Ingen 35 - 3632 kg/ha and Ingen 93 - 3744 kg/ha. Referring to the planting dates, the highest yields were recorded on the optimal planting dates. Ingen 35 variety provided yields at the level of 4265 kg/ha after the forerunner grain peas, 3448 kg/ha after the forerunner vetch-oat and 2770 kg/ha after the forerunner sunflower. The Ingen 93 variety recorded yields of 4176 kg/ha after the forerunner grain peas, 3778 kg/ha after vetch-oat and 2929 kg/ha after the forerunner sunflower. In the case of the seeding rate, the highest yields were obtained for the variant 5.0 mln/ha, which ensured 3161 kg/ha for the Ingen 93 variety and 3077 kg/ha for the Ingen 35 variety. The dominant influence degree on the grain production belongs to the forerunner crop: 67.11% for Ingen 35 and 73.16% for Ingen 93. The influence of the planting dates was of 31.92% and 25.56% respectively for the varieties. The highest percentage of protein content was recorded after the forerunner grain peas – 14.11% for the Ingen 93 variety. It was established the tendency to increase the protein content from the optimal to the late planting dates for both varieties and after all forerunner crops.The highest protein yield was recorded after the forerunner grain peas in both varieties: 426.1 kg/ha for Ingen 35 and 435.5 kg/ha for Ingen 93

Residual internal stress in partially crystallized photothermorefractive glass: Evaluation by nuclear magnetic resonance spectroscopy and first principles calculations

In some circumstances, the mechanical and optical properties of multiphase brittle materials strongly depend on the level of residual micromechanical stresses that arise upon cooling due to thermal and elastic mismatch between the constituent phases. Here we study the residual internal stress in a partially crystallized oxyfluoride glass, best known as photothermorefractive (PTR) glass. This material is composed of a glass matrix with embedded nanosize sodium fluoride (NaF) crystals. Using both the Selsing model and solid-state nuclear magnetic resonance in combination with first principles calculations we found that the crystals are under a tensile stress field of approximately 610-800 MPa. For this stress level the estimated critical crystal diameter for spontaneous cracking is about 2300-1900 nm, which greatly exceeds the observed diameters of 7-35 nm. Hence no spontaneous cracking is expected for the PTR glasses. First principles calculations indicate that the stress induced change of the refractive index of the NaF crystals is about -0.08%, which agrees with the observed refractive index changes

Imaging diagnostics coupled with non-invasive and micro-invasive analyses for the restoration of ethnographic artifacts from French Polynesia

In this paper, two different objects from the ethnographic collection of the museum of the Congregation of the Sacred Hearts of Jesus and Mary (Rome), a Polynesian barkcloth (tapa) and a Polynesian headdress in feathers (pa’e ku’a), were investigated to characterize the materials, to evaluate their state of conservation and address the restoration activities. Imaging methods such as multispectral imaging, 3D ultraviolet induced fluorescence and scanning electron microscopy have been integrated with analytical techniques such as X-ray fluorescence spectroscopy, Fourier transform infrared and surface enhanced Raman spectroscopy. Imaging investigations allowed us to differentiate constitutive materials and study their distribution, such as the yellow dye in the tapa used to trace the geometrical pattern and the psittacofulvins responsible for the feathers’ colors in the headdress. The combination of molecular spectroscopy, supported by observation under a scanning electron microscope, allowed us to propose a characterization of the organic painting materials (Morinda citrifolia, Curcuma longa) used for the tapa, and of the type of feathers (from Vini kuhlii bird) and vegetal fibers (Cocos nucifera L.) used to realize the headdress, as well as enabling the identification of degradation products and microorganisms affecting the artifacts before restoration. Fourier transform infrared spectroscopy detected the organic materials used as adhesives for the tapa and headdress: a polysaccharide, probably starch, for the tapa and a natural rubber from Cerbera manghas L. for the headdress. The results of the multi-analytic diagnostic campaign enabled the choice of proper restoration materials, compatible with the original ones, and helped us develop effective protocols for the artifacts’ conservation, such as laser cleaning of the feathers

Inhibition of cathepsin B by caspase-3 inhibitors blocks programmed cell death in <i>Arabidopsis</i>

Programmed cell death (PCD) is used by plants for development and survival to biotic and abiotic stresses. The role of caspases in PCD is well established in animal cells. Over the past 15 years, the importance of caspase-3-like enzymatic activity for plant PCD completion has been widely documented despite the absence of caspase orthologues. In particular, caspase-3 inhibitors blocked nearly all plant PCD tested. Here, we affinity-purified a plant caspase-3-like activity using a biotin-labelled caspase-3 inhibitor and identified Arabidopsis thaliana cathepsin B3 (AtCathB3) by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Consistent with this, recombinant AtCathB3 was found to have caspase-3-like activity and to be inhibited by caspase-3 inhibitors. AtCathepsin B triple-mutant lines showed reduced caspase-3-like enzymatic activity and reduced labelling with activity-based caspase-3 probes. Importantly, AtCathepsin B triple mutants showed a strong reduction in the PCD induced by ultraviolet (UV), oxidative stress (H2O2, methyl viologen) or endoplasmic reticulum stress. Our observations contribute to explain why caspase-3 inhibitors inhibit plant PCD and provide new tools to further plant PCD research. The fact that cathepsin B does regulate PCD in both animal and plant cells suggests that this protease may be part of an ancestral PCD pathway pre-existing the plant/animal divergence that needs further characterisation

СОЗДАНИЕ НОВЫХ ФОРМ ШТАМБОВОГО ТОМАТА И ИХ ИСПОЛЬЗОВАНИЕ В СЕЛЕКЦИИ

Tree-shaped plants of tomato have many useful traits, which gain them advantages over common tomato forms. In world plant collection there are over 200 accessions, cultivars and hybrids of tree-shaped tomato. The aim of the study was to develop new initial tomato accessions for breeding program for tree-shaped cultivars and hybrids that are distinguished by a shape, fruit weight and color, improved by interspecific hybridization chemical composition and resistance to the major diseases. The tree-shaped breeding lines: ‘196/12’, ‘374/08’, ‘909/14’, ‘911/14’ and other were observed with the use of interspecific hybridization and selection in the population F2-F4. The selected lines passed the trial in artificially infected condition with Alternaria, viral diseases (MToV, TSWV) and phytoplasmas. Among breeding lines assessed the ‘911/14’, ‘374/08’ and‘40/11’ were less affected by complex of pathogens. The lines ‘196/12’ and ‘909/14’ passed an assessment in the nursery for variety trial in naturally and  provocatively infected conditions with major pathogens. Both breeding lines had an advantage over standard accession ‘Laguna’ and ‘Maraphon’ for total yield capacity and standard fruit harvest; it was more by 9.6% and 52.2% and 9.5% and 53.4% respectively. Fruits of lines 196/12 and 909/14 had good taste quality with high content of dry matter (5.8% and 6.8%), sugars (3.3% and 3.1%), vitamin C (22.2 and 24.8 mg/100 grams). The selected tree-shaped accessions have been used to develop heterotic hybrids and to be sources of economically valuable traits.Штамбовые   растения  томата имеют  ряд полезных признаков, которые создают им преимущество над обыкновенными  растениями.

Application of the Transverse Chirped Bragg Grating (TCBG - a reflecting volume Bragg grating with continuously variable resonant wavelength across the aperture) for the narrowband tunable ring-cavity fiber laser is presented. The main advantage of the use of TCBG is that its linear translation allows continuous tuning of emission wavelength within 5-10 nm band. Yb doped fiber laser operating in the wavelength range of 1050-1055 nm of narrowband emission up to 2.3 W is demonstrated. © 2013 SPIE

200W, 350Fs Fiber Cpa System Enabled By Chirped-Volume-Bragg-Gratings And Chirally-Coupled-Core Fiber Technology

Fiber-CPA-laser-systems are an extremely promising technology for generating ultrashort (fs-scale) pulses at high average-powers (hundreds-of-Watts to kW) while still producing diffraction-limited beams and being compact and robust compared to bulk-solid-state systems. Two obstacles still must be overcome to realize this potential, however. First, there is a need for stretchers and compressors that can yield long stretched pulse-durations (hundreds-of-ps to nanoseconds) and can handle high-energies and average-powers, yet are still simple and compact, so as to not offset the benefits of fibers. Secondly, large-core-fibers are needed for amplifiers and other components that are robustly singlemode. In this work, we present an Yb-fiber-CPA-system based on two novel technologies to overcome the aforementioned problems. Chirped-volume-Bragg-gratings (CVBGs), slabs of photo-thermo-refractive glass of cmscale with a quasi-periodic longitudinal index-of-refraction, are used for the stretcher and compressor. Their compactness and simplicity makes them compatible with fiber-laser benefits, and have excellent power handling capabilities are. Chirally-coupled-core (CCC) fibers, which have large core diameters (35μm here), yet are robustly single mode and can be coiled and spliced, are used for the power-amplifiers. Using these technologies, a system producing a record 200W of power (130W compressed) with 350fs pulse durations is demonstrated, and the potential kW-level-scaling is explored. © 2010 Copyright SPIE - The International Society for Optical Engineering
