Patterns of drilling predation of cassid gastropods preying on echinoids from the Middle Miocene of Poland

Test−drilling predation by cassid gastropods on minute clypeasteroid echinoids has been studied in the fossil assemblage of the Heterostegina Sands (middle Miocene, Holy Cross Mountains, Poland). The analysed prey, collected from two sublithofacies of the Heterostegina Sands (coarse−grained Heterostegina Sands and fine−grained Heterostegina Sands), represent three species of Echinocyamus (E. linearis, E. pusillus and E. pseudopusillus). The drill holes were produced presumably by one cassid species, Semicassis miolaevigata. The investigation showed that drilling predation intensities varied among the prey species. Within both fine− and coarse−grained sands, E. linearis was drilled more frequently than E. pusillus. An intermediate value of drilling predation was recognised for E. pseudopusillus. The intensities of drilling pre− dation recognised for some of the prey species (E. pusillus) varied also between (but never within) the sublithofacies. Drilling predation was both size− and site−selective. Larger individuals of E. linearis and E. pusillus were attacked more frequently and the aboral side of the test of all Echinocyamus species was drilled preferentially. An extremely high con− centration of drill holes was observed in the apical disc and petals. Results obtained for the most abundant prey (E. linearis) indicate that the predatory behaviour of large cassids was somewhat different from those typical of small cassids. Large cassids drilled and consumed their prey almost always individually, whereas small cassids sometimes preyed upon the urchins in a group. Large cassids displayed also a higher site−selectivity. They more frequently drilled in the petals and apical disc. The patterns of drilling predation were most likely controlled by the potential energetic value of prey (mea− sured by the internal volume/test thickness ratio), prey and predator mobility, prey mode of life, thickness and porosity of the prey's tests, as well as by the proportions between the size of the prey and size of the predator. The results suggest that the mode of life of the prey and its test structure can influence the drill hole morphology.
Investigating the Influence of Shareholder Mechanisms on the Perceived Performance of Listed Firms in Nigeria

The current debate on the issues of shareholder rights to firm performance has grown as a topic of research both in the developed and emerging economy. There is serious concern regarding the effectiveness of the board transparency and accountability, company image and the rights of the shareholders in recent times. This paper investigated the influence of shareholders mechanisms on the perceived performance of listed firms in Nigeria. The study is guided byagency theory and supported by the stewardship theory. The questionnaire was used as an instrument for data collection. 247 questionnaires were administered with 117 duly completed and returned. Hence, the number of completed valid questionnairesis 114. However, data were analysed using Partial Least Square Structural Equation Modeling (PLS-SEM). Empirical findings showed that board transparency/accountability and shareholder right were significantly and positively related to perceived firm performance. Whilethe company image did not show any significant link to perceived firm performance.Hence, based on the researches knowledge, this is the first of its kind to adopt primary data to investigate the influence of shareholders’ rights mechanisms on the perceived performance of listed firms in Nigeria. Therefore, the findings of this study,provide researchers, policymakers, firms, stakeholders, and the agencies of the government with a better picture of the transparency and accountability and the right of the shareholder. The study recommends that listed firms in Nigeria should adhere to professional ethics and best business practices such as financial prudence and accountability to their board of directors.
Characteristics of a Mg-palygorskite in Miocene rocks, Madrid Basin (Spain)

Palygorskite in Miocene mudstones, palustrine limestones and calcretes from the Esquivias locality (Madrid Basin, Spain) has been analyzed by X-ray diffraction, infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and analytical electron microscopy to determine its characteristics and chemical composition. Other palygorskites from the literature are used as references. The mean structural formula obtained from the analysis of isolated particles is (Si7.87Al0.13)O20($({\rm{A}}{{\rm{l}}_{1.04}}{\rm{Fe}}_{0.20}^{3 + }{\rm{M}}{{\rm{g}}_{3.11}}{\square _{0.65}})$(Al1.04Fe0.203+Mg3.11□0.65))(OH)2(OH2)4(Ca0.02K0.05Na0.08). This palygorskite has the largest Mg content reported in the literature, and it seems that, chemically, it fills the ‘compositional gap’ existing between sepiolite and palygorskite. Infrared spectroscopy reveals the absence of trioctahedral Mg and therefore the possibility of the existence of magnesic clusters in the ribbons is discounted. An homogeneous distribution of the octahedral cations (Al, Fe3+ and Mg) along the ribbons is proposed.
Persistency of Common Fodder Grasses under Melia Azedarach Based Silvipastoral System

An experiment was conducted from July 2004 to October 2005 at IAAS Livestock Farm, Rampur under 14 years old Melia azedarach tree(maintained 1200 stems/ha) shade to study the dried weight yield potentiality of common fodder grasses, grown with tropical legumes and their persistency. A split Plot Design (SPD) was employed with three replications with three different canopy levels (trees pruned at 3m, 4m and 5m from the ground and one open) as main plots and four forage mixtures as subplots. Shade level was maintained by pruning the trees throughout the experiment. The shade level at the initial phase was measured by LUX-101 Lux Meter (Model No.44147) at August, 2004 and was standardized for low (72%irradiance to open) medium (64%irradiance to open) and heavy (58 % irradiance to open). Number of tillers/plant in fodder grasses decreased as the shade level increased in all the harvests whereas blue panic always had the highest number of tillers/plant (P 0.05) Furthermore, highest cumulative dried weight yield was in open condition (63.29 t/ha) followed by low shade 26.50 t/ha (42% to that of open t/ha) whilst, the cumulative dried weight yield in medium shade remained 27% and it was only 21% in heavy shade to that of open. It can be concluded that Panicum antidotale can be grown in summer under high density plantations at least for two harvests. The the selection of forage species is more important criterion of silvipastoral work than the maintenance of shade level.

Nonspecular x-ray scattering in a multilayer-coated imaging system

We present a rigorous theoretical treatment of nonspecular x-ray scattering in a distributed imaging system consisting of multilayer-coated reflective optics. The scattering from each optical surface is obtained using a vector scattering theory that incorporates a thin film growth model to provide a realistic description of the interfacial roughness of the multilayer coatings. The theory is validated by comparing calculations based on measured roughness to experimental measurements of nonspecular scattering from a Mo–Si multilayer coating. The propagation of the scattered radiation through the optical system is described in the context of transfer function theory. We find that the effect of nonspecular scattering is to convolve the image with a point spread function that is independent of the coherence of the object illumination. For a typical soft x-ray imaging system, the scattering within the image field from the multilayer coatings is expected to be slightly greater than for single surfaces (as normal.
Cohomological descent theory for a morphism of stacks and for equivariant derived categories

In the paper, we find necessary and sufficient conditions under which, if is a morphism of algebraic varieties (or, in a more general case, of stacks), the derived category of can be recovered by using the tools of descent theory from the derived category of . We show that for an action of a linearly reductive algebraic group on a scheme this result implies the equivalence of the derived category of -equivariant sheaves on and the category of objects in the derived category of sheaves on with a given action of on each object.

A reconsideration of disk properties in Herbig Ae stars

This paper presents state-of-the-art spectral energy distributions (SEDs) of four Herbig Ae stars, based in part on new data in the mid and far-infrared and at millimeter wavelengths. The SEDs are discussed in the context of circumstellar disk models. We show that models of irradiated disks provide a good fit to the observations over the whole range of wavelengths. We offer a possible solution to the long-standing puzzle caused by the excess emission of Herbig Ae stars, where a large fraction of the stellar luminosity is re-radiated between ~1.25 and 7 μ m, with a peak at about 3 μ m. We suggest that this general behaviour can be caused by dust evaporation in disks where the gas component is optically thin to the stellar radiation, as expected if the accretion rate is very low. The creation of a puffed-up inner wall of optically thick dust at the dust sublimation radius can account for the near-infrared characteristics of the SEDs. It can also naturally explain the H and K band interferometric observations of AB Aur (Millan-Gabet et al. [CITE]), which reveal a ring of emission of radius ~0.3 AU. Finally, irradiated disk models can easily explain the observed intensity of the 10 μ m silicate features and their variation from star to star.
Hysteretic Magnetotransport in SmB6 at Low Magnetic Fields

Utilizing Corbino disc structures, we have examined the magnetic field response of resistivity for the surface states of SmB6 on different crystalline surfaces at low temperatures. Our results reveal a hysteretic behavior whose magnitude depends on the magnetic field sweep rate and temperature. Although this feature becomes smaller when the field sweep is slower, a complete elimination or saturation is not observed in our slowest sweep-rate measurements, which is much slower than a typical magnetotransport trace. These observations cannot be explained by quantum interference corrections such as weak anti-localization. Instead, they are consistent with behaviors of glassy surface magnetic ordering, whose magnetic origin is most likely from samarium oxide (Sm2O3) forming on the surface during exposure to ambient conditions.
Critical Aging Segments of Power Transmission Line

Nowadays, blackouts or sags of a conductor are threatening the safety and stable run of the power transmission lines. These phenomena happen due to the environmental conditions which change over the time, such as aging or temperature variations, precipitation and hotspots of power transmission lines as a result of extreme weather conditions. A precipitation condition result loses of heat from transmission line. Besides, the conductor aging and hotspots of a transmission line can lead to the loss of conductor strength, which may increase the probability of blackouts. All the damage suffers by the transmission line will cause the service interruption and required high cost to repair. Consequently, appropriate methods are required to monitor the condition of power transmission lines where the segment of the power transmission line which requires more repair or reinforcement can be identified early. This research work introduces the new novel to identify the critical aging segments and the hotspot power transmission lines. This method depends on the information about the power transmission line and its environment such as temperature variations and characteristics of the conductors. Besides that, the effect of the weather and radiative parameters on the conductor temperature are being considered as well in this research. The results in this research work had discovered the most significant impacts the conductor aging behaviour was conductor temperature. Convection heat loss is more consequential that radiation heat loss in terms of determination the conductor temperature.
Low Temperature Internal Friction and Dynamic Modulus for Beach Wood

The dynamic elastic modulus and the internal friction of beech wood beams conditioned to various equilibrium moisture contents have been measured in the temperature range from 25 C to -130 C. The response curves show a marked transition around -90 C for wood with moisture contents at or above the fibre saturation level. The transition is similar to those found for other microporous water-adsorbing materials such as hardened cement paste and porous glass. Decreasing moisture contents in the wood reduce the magnitude of the transition and shift the transition to higher temperatures. We believe the transition to be caused by a gradual solidification ("glass transition") of the adsorbed water.
The SWELLS survey – II. Breaking the disc–halo degeneracy in the spiral galaxy gravitational lens SDSS J2141−0001

The degeneracy among the disc, bulge and halo contributions to galaxy rotation curves prevents an understanding of the distribution of baryons and dark matter in disc galaxies. In an attempt to break this degeneracy, we present an analysis of the strong gravitational lens SDSS J2141-0001, discovered as part of the Sloan Lens ACS survey. The lens galaxy is a high-inclination, disc-dominated system. We present new Hubble Space Telescope multicolour imaging, gas and stellar kinematics data derived from long-slit spectroscopy and K-band laser guide star adaptive optics imaging, both from the Keck telescopes. We model the galaxy as a sum of concentric axisymmetric bulge, disc and halo components and infer the contribution of each component, using information from gravitational lensing and gas kinematics. This analysis yields a best-fitting total (disc plus bulge) stellar mass of log10(M*/M⊙) = 10.99+0.11- 0.25. The photometric data combined with stellar population synthesis models yield log10(M*/M⊙) = 10.97 ± 0.07 and 11.21 ± 0.07 for the Chabrier and Salpeter initial mass functions (IMFs), respectively. Assuming no cold gas, a Salpeter IMF is marginally disfavoured, with a Bayes factor of 2.7. Accounting for the expected gas fraction of ≃ 20 per cent reduces the lensing plus kinematics stellar mass by 0.10 ± 0.05 dex, resulting in a Bayes factor of 11.9 in favour of a Chabrier IMF. The dark matter halo is roughly spherical, with minor to major axis ratio q3, h= 0.91+0.15- 0.13. The dark matter halo has a maximum circular velocity of Vmax= 276+17- 18 km s-1, and a central density parameter of log10ΔV/2= 5.9+0.9- 0.5. This is higher than predicted for uncontracted dark matter haloes in Λ cold dark matter cosmologies, log10ΔV/2= 5.2, suggesting that either the halo has contracted in response to galaxy formation, or that the halo has a higher than average concentration. Larger samples of spiral galaxy strong gravitational lenses are needed in order to distinguish between these two possibilities. At 2.2 disc scalelengths the dark matter fraction is fDM= 0.55+0.20- 0.15, suggesting that SDSS J2141-0001 is submaximal. Based in part on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by AURA, Inc., under NASA contract NAS 5-26555. These observations are associated with programmes 10587 and 11978.
Assessment of Heavy Metals and Microbial Load of Groundwater Samples from Ibadan Metropolis Nigeria

The present study investigates groundwater quality in terms of heavy metals level and microbial contamination as well as the impact of bleaching powder on microbial load of groundwater samples in close proximity to a surface water body inside selected areas of Ibadan Nigeria. To do so, it collects nine water samples from three boreholes and six hand-dug wells from six locations, namely Eleyele, Wofun-Olodo, Oluyole Industrial Estate, Ogunpa, Olorunsogo, and Ojoo, keeping them in 750 mL plastic bottles. The samples are then divided by two, giving a total amount of 18 samples, with 3 and 6 duplicates apiece being treated with bleaching powder and the rest remaining untreated. Both sample sets have been analysed for water quality parameters such as pH, biochemical oxygen demand, and chemical oxygen demand, assessed using standard methods. The coliform count has been determined, using the pour plate method while heavy metal has been set by means of Atomic Absorption Spectrophotometer (AAS) after nitric acid digestion. Results show that the pH ranges within 6.0-6.5, BOD within 1.67-4.33mg of O2/L, and COD within 2.93-9.43, while heavy metal concentration is from 0.013 to 0.047 mg/L for lead, ND to 0.023 mg/L for chromium, and ND to 0.010 for cadmium. What is more, the coliform count in the samples is between 0.00 and 913.33 CFU/mL. Most of the samples exceed the WHO limits for heavy metals in drinking water, having significant levels of microbial contamination. Bleaching powder treatment alleviated the level of pollution to varying degrees; therefore, constant monitoring of groundwater source and treatment before drinking is of utmost importance.
Grain Quality Characteristics and Milling Performance of Full and Partial Waxy Durum Lines

ABSTRACT Mutation of the gene coding for the granule bound starch synthase (waxy protein) leads to reduced amylose content in cereal endosperm. Durum wheat (Triticum turgidum L. var. durum) has one waxy locus in each of its two genomes. Full waxy durum wheat is produced when both genomes carry the waxy null alleles. When only one locus is mutated, partial waxy durum wheat is obtained. Partial and full waxy near-isogenic lines of durum wheat developed by a breeding program were analyzed as to their quality characteristics. Amylose was largely eliminated in full waxy lines; however, no reduction in amylose content was detected in partial waxy lines. The waxy mutation did not affect grain yield, kernel size, or kernel hardness. Full waxy durum lines had higher kernel ash content, α-amylase activity, and a unique nonvitreous kernel appearance. Protein quality, as evaluated by SDS microsedimentation value, gluten index, and wet gluten was slightly lower in the full waxy lines than in the other genotypes. Howev.
HEAT-INDUCED CHANGES IN SOLUBILITY AND SURFACE HYDROPHOBICITY OF β-LACTOGLOBULIN

Heat-induced structural changes of β-lactoglobulin were studied at temperatures ranging from 67.5 to 82.5°C and at pH 7.5. These changes were followed by measurement of surface hydrophobicity and protein solubility. Results indicate that β-lactoglobulin is sensitive to heat-induced interchange reactions with consequences for the protein solubility.
Analytical calibre of high performance liquid chromatography and ion exchange chromatography resin methods in estimation of glycated hemoglobin: a comparitive study

Aim: The present study is aimed to assess the precision and reproducibility of Ion Exchange Chromatography (IEC) resin method in comparison to High Performance Liquid Chromatography (HPLC) with respect to the estimation of Glycated Haemoglobin (HbA1c). Materials and Methods: 72 subjects who visited Clinical Biochemistry Laboratory, Kasturba Medical College Hospital, Ambedkar Circle, Mangalore for HbA1c estimation were enrolled in the study. HbA1c levels were estimated by both the techniques. Results: The mean age of the study subjects was 53 ± 15.35 years and their plasma HbA1c levels estimated by HPLC and IEC were (7.44 ± 2.02) and (6.53 ± 1.58) respectively. The sensitivity and specificity were obtained from Receiver Operator Curve (ROC). The Area under Curve (AUC) for HPLC was 1 whereas IEC was 0.824. With respect to both IEC and HPLC, women showed significantly higher HbA1c levels (7.70 ± 2.20 vs. 6.90 ± 2.0) than men (6.70 ± 1.40 vs. 6.70 ± 0.850). Similar values in both the methods were found in men. Conclusion: Although HPLC is considered to be the gold standard method for estimation of HbA1c, IEC being affordable can serve as an alternative when performed carefully with strict precautions especially in basic laboratories providing diagnostic support for the people of lower socio-economic status.
Cytokinin‐induced upregulation of cytokinin oxidase activity in tobacco includes changes in enzyme glycosylation and secretion

Regulation of cytokinin oxidase (CKX) activity in relation to enzyme glycosylation and secretion was studied in wild-type (WT) and transgenic conditionally isopentenyltransferase gene (ipt)-expressing (IPT) tobacco (Nicotiana tabacum L. cv. Wisconsin 38) cell suspensions, calli and leaves. An increase in endogenous cytokinin content due to the tetracycline (Tc)-induced derepression of the ipt gene transcription or surface application of N 6 -benzylaminopurine (BA) resulted in significant enhancement of CKX activity in all these plant material. As revealed by Concanavalin A-Sepharose 4B chromatography the cytokinin-induced enhancement of CKX activity was associated predominantly with the N-glycoform of the enzyme (10- to 15-fold increase) in calli and leaves. Application of BA to the culture media of WT and IPT cell suspensions and the derepression of the ipt by Tc substantially enhanced endogenous levels of isoprenoid cytokinins and CKX activity in both cells and the culture medium. Most CKX activity in control, BA- and Tc-treated cells was associated with the non-glycosylated form of the enzyme, whereas the majority of CKX activity in the culture media was due to the glycosylated form. The pH optimum of CKX in cells (pH 8.5) differed considerably from that in the culture medium (pH 6.0). No significant differences were found in apparent K m (iP) values of CKX between control, BA- and Tc-treated IPT cells and media or between purified glycosylated and non-glycosylated CKX. These results suggest that cytokinins induce changes in the proportions of glyco- and non-glycoforms of the enzyme in multicellular calli and leaves, and influence its secretion to the cell exterior.
Heavy Metal Levels in Farmed and Wild Fishes of Aegean Sea and Assessment of Potential Risks to Human Health

The aim of this study was to determine the levels of Ag, Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn in wild seabream (Sparus aurata), blotched picarel (Spicara maena), pandora (Pagellus erythrinus) fished from the Aegean Sea and the farmed seabream (Sparus aurata), and to assess the risks depending on their consumption by humans. A total of 40 fishes were collected and the metal levels were determined using ICP-OES. The metal levels were determined to be Ag (Nd), Al (3.20-8.87), Co (0.01-0.01), Cr (0.02-0.51), Cu (0.96-1.28), Fe (0.23-4.30), Mn (0.15-0.39), Ni (0.13-0.22), Pb (0.00-0.10) and Zn (6.18-7.30) (mg kg -1 w.w.) in the study. No Ag or Cd were found in the samples. The heavy metal levels were below the national and international legal limits. The target hazard quotient (THQ) and total target hazard quotient (TTHQ) method was used to determine the possible risks of the heavy metals on human health. THQ and TTHQ values were all less than 1 and it was concluded that they do not pose any risks in terms of human health.
