Abstract:

The structure of β-DL-methionine, C5H11NO2S, in the space groupC2/c, is here confirmed to be fully ordered all the way up to the phase transition at approximately 326 K, where displacive sliding of molecular bilayers gives the disorderedP21/cα form [data at 340 K; Görbitz (2014).Acta Cryst.E70, 341–343]. The geometry of hydrogen bonds in LD–LD hydrogen-bonding patterns [Görbitzet al.(2009).Acta Cryst.B65, 393–400] at the hydrophilic core of each molecular bilayer are virtually unperturbed by the phase shift, but the C—C—S—C torsion angle of the side chain changes fromtransat 320 K togauche+ fo

Abstract:

Leech neurons in culture sprout rapidly when attached to extracts from connective tissue surrounding the nervous system. Laminin-like molecules that promote sprouting have now been isolated from this extracellular matrix. Two mAbs have been prepared that react on immunoblots with a approximately equal to 220- and a approximately equal to 340-kD polypeptide, respectively. These antibodies have been used to purify molecules with cross-shaped structures in the electron microscope. The molecules, of approximately equal to 10(3) kD on nonreducing SDS gels, have subunits of approximately equal to 34

Abstract:

Under low nutrient conditions hyphae of certain fungi are strongly attracted to microcolonies of bacteria belonging to the genera Pseudomonas and Agrobacterium. Hyphae of the fungi penetrate the microcolonies and proliferate to produce coral-loid, haustorial-like masses of absorptive hyphae. The bacteria in the colonies are lysed and the contents apparently absorbed as a nutrient source by the fungi. The four fungi that demonstrated this capability were Agaricus brunnescens (= A. bisporus), Coprinus quadrifidus, Lepista nuda, and Pleurotus ostreatus. Approximately 100 additional species belong

Abstract:

Air pollution is a challenge for municipal authorities. Increased emission of PM10 and PM 2.5 particles is particularly noticeable in Poland primarily the autumn and winter period. That is due to the start of the heating season. According to the above data, road transport accounted for approximately 5% of the creation of PM10 particles, ca. 7% of PM2.5 and approximately 32% for NOx. In Poland, suspended particles (PM10 and PM2.5) cause deaths of as many as 45,000 people a year. The issue of smog also affects other European cities.

Limitations in propagule dispersal, establishment, and maintenance were studied at Bird River (50°25′ N, 95°41′ W) between October 1979 and October 1982. Propagules studied were stem units (pads) because this cactus propagates entirely by vegetative means in this region. Mature terminal pads broke off most easily in the late spring while turgid and rolled downhill (geochory), thus establishing new plants locally. Some pads fell into

We coined the terms immediate and delayed apoptosis to help distinguish the mechanistic differences between apoptosis and programmed cell death (or delayed apoptosis) which have been incorrectly used as synonyms. This confusion occurred primarily because these two cell death mechanisms are morphologically identical. However, k

Abstract The presence of salicylates in urine reduces the signal in Emit assays (Syva), potentially yielding false-negative drugs-of-abuse screening results. We demonstrate that the principal urinary metabolite of salicylate, salicyluric acid (SUA; 2-hydroxybenzoylaminoacetic acid), interferes with the measurement of NADH formed in the assay by reducing the molar absorptivity of NADH at 340 nm. Thus, for a given concentration of d.a.u. analyte the change in absorbance over the assay time interval is less in the presence of SUA.

From 16 to 64 Hz, c slightly increased because of the viscoelastic properties of the wall tissues. Between 64 and 200 Hz, c was relatively constant and less than the free-field speed of sound (c0 = 340 m/s), with values smaller at TS (140 +/- 39 m

Abstract:

Sound may be defined as any pressure variation (in air, water or other medium) that the human ear can detect. Just like dominoes, a wave motion is set off when an element sets the nearest particle of air into motion. This motion gradually spreads to adjacent air particles further away from the source. Depending on the medium, sound propagates at different speeds. In air, sound propagates at a speed of approximately 340 m/s. In liquids and solids, the propagation velocity is greater 1500 m/s in water and 5000 m/s in steel [2].

Abstract:

There is increasing interest in the use of white clover rich swards in dairy cattle systems in response to evironmental pressures and the introduction of milk quotas. White clover (Trifolium repens) in association with Rhizobium bacteria in a mixed sward receiving no fertilizer nitrogen can produce yields equivalent to a grass sward receiving approximately 200 kg N/ha/annum. Field scale cutting experiments (Roberts et al, 1989) have deomstrated that under an intensive 3-cut silage regime a grass/white clover sward receiving no nitrogenous fertilizer can yield 0.71 of the DM herbage output of a

Abstract:

CO2 methanation is a promising technology to store renewable energy by converting carbon dioxide with green hydrogen into methane, which is known as power to gas (PtG). In this study, CO2 methanation performance of a Ni/Al2O3 catalyst was investigated in a bubbling fluidized bed (BFB) and the axial gas concentration, temperature, and CO2 conversion were densely analyzed. Moreover, a modified reaction kinetic model was proposed, and the results were compared with experimental data. The bed temperature increased by 11 °C from 340 °C to 351 °C within the first 30 mm of the fluidized bed. The CO2

The present paper focuses on the magnetoelectric coupling in dimensionally graded ferrite-piezoelectric bilayers in the electromechanical resonance region. Using the bilayer as a transducer which converts the ac magnetic field into an ac electric field shows that the transmission coefficient equals approximately -83 dB for zero bias magnetic field and -44 dB for bias field of 340 Oe. Thus, applying the DC field enables one to obtain the transmission coefficient variation range of 39 dB for the investigated structure. The phenomenon is of importance for the realization of multifunctional magnet

ABSTRACT Compressive soil properties are typically used for the understanding of compaction process. As an alternative to laboratory tests, pedo-transfer functions have been used to estimate the mechanical behaviour of soil as a function of soil physical parameters. The impact of soil bulk density (BD) and gravimetric water content (w) was examined on soil strength and pedo-transfer functions were proposed to predict the precompression stress (σp) in an Ultisol cultivated with sugarcane.

Control experiments revealed that trisodium citrate dihydrate played an important role in regulating the morphologies of ZnO products. The morphology of the ZnO product evolved from nanowires to hollow microspheres with the addition of trisodium citrate dihydrate. The sensor response of ZnO hollow microspher

All structural parameters are in good agreement with those of TMU determined in the gas phase and with those of amide derivatives in the liquid phase.

However, the difficulty of recovering ancient DNA from fossils in temperate East Asia has limited our understanding of their evolutionary history.

Up to 200 mol m-3aC1, all emerged seedlings reached the first leaf stage, although shoot dry weight of emerged seedlings at 200 mol m-3 NaCl was reduced to 64% of that of seedlings under non-saline conditions. During later plant growth, shoot growth (dry weight) had a salt tolerance threshold of 20 mol m-

An individual α-Fe2O3 thin film-based photodetector’s rapid photoresponse time of 1.6 ms and responsivity of ~ 1 mA/W can be attributed to the band gap and chemisorption of oxygen on the film’s surface.
