description: The end point energies of nuclear $β$ decays have been measured with a segmented planar Ge LEPS detector using both singles and coincidence techniques. The $β- γ$ coincidence has been performed with a segmented planar Ge LEPS and a single 10$\%$ HPGe detector. The $γ$ ray and $β$ particle responses of the Segmented planer Ge LEPS detector were studied using monte carlo simulation code GEANT3. The experimentally obtained $β$ spectrum was in reasonably good agreement with the simulation results. The experimental end point energies are determined with substantial accuracy for some of the known $β$ decays in $^{106}$Rh, $^{210}$Bi and $^{90}$Y. The end point energies corresponding to three weak branches in $^{106}$Rh $\rightarrow$ $^{106}$Pd decay has been measured for the first time.

title: Testing wheat for internal infesting insects with an electrically conductive roller mill

Publisher: name: Julius Kühn-Institut
Year: 2018

description: Although grain is always inspected for adult insects and insect damaged kernels upon shipping and receiving, immature insects living inside the kernels of grain cannot be readily detected. A laboratory roller mill was modified to measure and analyze the electrical conductance of wheat as it was crushed. The electrical conductance of normal wheat kernels is low and fairly constant. In contrast, the electrical conductance of infested wheat kernels produces a sudden change in the electrical signal. The peak height of the electrical spike depends on the size of the larvae and the resulting contact of the crushed larvae between the rolls. This instrument was designed to test wheat with moisture content of 13.5% or less. The laboratory mill can test a kilogram of wheat in less than 2 min. Hard red winter and soft red winter wheat samples were used in experiments. Known numbers of infested kernels were added to the wheat samples. The infested kernels contained larvae of rice weevils and lesser grain borers sorted into large, medium, and small size groups. The instrument detected ~8 of 10 infested kernels per 100 g of wheat with large-larvae (fourth instar or pupae). It detected ~7 of 10 infested kernels with medium-larvae (second or third instar) and ~5 of 10 infested kernels infested with the small-larvae (first or second instar). Under reasonable grain moisture and careful sample handling, there were no non-infested kernels classified as insect infested. The mill can lead to rapid and automated detection of infested wheat.

description: This study was conducted to show the effects of high PAH levels on the external and internal structures as well as the functioning of a Poaceae species – Bermuda grass – during phytoremediation process. Two modalities – Tn: unpolluted planted soil and Tp: polluted planted soil – are applied to the monoculture of Bermuda grass for pollution at 10%, 20%, and 30% (weight/weight) with fuel oil, and co-cropping with Goosegrass in soils polluted at 10%. Morphological results revealed that monoculture is better than co-cropping as the sociability of the two species is negatively affected by PAHs. Contrary to monoculture, in the co-cropping the relative growth rate of Bermuda grass morphological parameters is decreasing over time in Tp. For monoculture, the aboveground plant density of Bermuda grass in Tp is not significantly different to Tn, while its specific root length is higher in Tn than Tp. Anatomical and physiological analyses of Bermuda grass show that PAHs impacted the hydromineral nutrition of this species. In fact, the vascular bundles of the stems and roots of Bermuda grass were less numerous in Tp, and the chlorophyll synthesis was 50% inhibited. Despite the slower physiological processes of Bermuda grass in polluted soils, the phytotoxicity of very high PAH levels is not fatal to this species. Its development and evolution on soils highly polluted with PAHs and its phytoremediation potential (more than 95% for total petroleum hydrocarbons and up to 100% for chrysene) therefore recognize it as particularly suitable for hydrocarbon phytoremediation, with wide geographical application thanks to its cosmopolitan nature.

description: Agricultural crops infected with vector-borne pathogens can suffer severe negative consequences, but the extent to which phytopathogens affect the fitness of their vector hosts remains unclear. Evolutionary theory predicts that selection on vector-borne pathogens will favour low virulence or mutualistic phenotypes in the vector, traits facilitating effective transmission between plant hosts. Here, we use a multivariate meta-analytic approach on 115 effect sizes across 34 unique plant–vector–pathogen systems to quantify the overall effect of phytopathogens on vector host fitness. In support of theoretical models, we report that phytopathogens overall have a neutral fitness effect on vector hosts. However, the range of fitness outcomes is diverse and span the parasitism–mutualism continuum. We found no evidence that various transmission strategies, or direct effects and indirect (plant-mediated) effects, of phytopathogens have divergent fitness outcomes for the vector. Our finding emphasizes diversity in tripartite interactions and the necessity for pathosystem-specific approaches to vector control.

description: The phase behaviour of two-component bottle-brush polymers with fully flexible backbones under poor solvent conditions is studied via molecular-dynamics simulations, using a coarse-grained bead-spring model and side chains of up to $N=40$ effective monomers. We consider a symmetric model where side chains of type A and B are grafted alternately onto a flexible backbone. The aim of this study to explore the phase behaviour of two-component bottle-brushes depending on parameters, such as as the grafting density $σ$, the backbone length $N_b$, the side-chain length $N$, and the temperature $T$. Based on a cluster analysis, we identify for our range of parameters the regimes of fully phase separated systems, i.e., A-type side chains form one cluster and B-type chains another, while the interface that separates these two clusters contains the backbone monomers. We find that pearl-necklace or Janus-like structures, which normally occur for bottle-brush polymers with rigid backbones under poor solvent conditions, are fully attributed to the backbone rigidity, and, therefore, such structures are unlikely in the case of bottle brushes with fully flexible backbones. Also, a comparative discussion with earlier work on the phase behaviour of single-component bottle-brush polymers with flexible backbones is performed.

description: Dried distiller’s grains and solubles, DDGS, is a valuable commodity with substantial international trade. Vietnam discovered an infestation of Trogoderma inclusum, an actionable quarantine pest, in DDGS from the USA in 2012. All subsequent shipments to Vietnam were required to be fumigated. A shipment to Vietnam from the USA 2015 was then discovered with T. variabile. We surveyed the presence and activity of T. inclusum and T. variabile at locations in the USA that provide DDGSs for shipment to Vietnam. Seven facilities in four states that either produced DDGSs or that facilitated bulk shipments were studied. Pheromone traps were deployed at each location and monitored for several weeks. T. variaible was trapped at all seven sites while T. inclusum was trapped at just five of these. T. variabile were captured in nearly every trapping period and at higher numbers than T. inclusum at five locations, while two locations captured more T. inclusum than T. variabile. Spatial variation seemed to occur within each site, but there was no common pattern among facilities. Substantial numbers of beetles were caught in the outdoor sticky flight traps for most locations, except for relatively low flight trap numbers at locations 1, 4 and 6. The results show that T. variabile and T. inclusum are commonly associated with DDGSs produced in the USA, that these beetles could infest product being shipped overseas, and provide information that can be used to develop risk assessment and pest management programs for the future.

description: We study spatial coherence properties of a system composed of periodic silver nanoparticle arrays covered with a fluorescent organic molecule (DiD) film. The evolution of spatial coherence of this composite structure from the weak to the strong coupling regime is investigated by systematically varying the coupling strength between the localized DiD excitons and the collective, delocalized modes of the nanoparticle array known as surface lattice resonances. A gradual evolution of coherence from the weak to the strong coupling regime is observed, with the strong coupling features clearly visible in interference fringes. A high degree of spatial coherence is demonstrated in the strong coupling regime, even when the mode is very excitonlike (80%), in contrast to the purely localized nature of molecular excitons. We show that coherence appears in proportion to the weight of the plasmonic component of the mode throughout the weak-to-strong coupling crossover, providing evidence for the hybrid nature of the normal modes.

This route has been developed to improve the performances of superconducting MgB2 powders, which can be directly synthesized from this nano-structured boron precursor by following the ex-situ or the in-situ P.I.T. method during the manufacturing of tapes, wires and cables. All the procedure steps are explained and the chemical-physical characterization of the boron powder, using x-ray diffraction (Xrd), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques, is reported. Furthermore, a comparison with commercial boron is given. Preliminary results of the magnetic and electrical characterization, such as the critical temperature (TC) and the transport critical current density (JC t), for the MgB2 tape are reported and compared with the tape prepared with commercial boron.

description: The COVID-19 pandemic affected many areas of public life and industry. This also applies to research particularly that relies on scientific studies with test persons. In order to minimize the risk of infection, several aspects of experiment design including the setting might require alteration. An extensive review of the latest research involving the COVID-19 pandemic as a blueprint for dealing with other health situations has been conducted in order to develop a step-by-step approach to plan a study with regard to infection protection. As a result, a generic six-step concept was developed that is applicable for scientific studies in both stationary rooms and vehicles while being adaptable to the respective circumstances. The infection protection measures determined through research were implemented in the individual sub-steps from study planning to execution. They allow a step-by-step approach to prevent infections in scientific studies with different settings during a pandemic and in situations where increased hygiene measures are required.

description: Soil erosion by water is a widespread phenomenon throughout Europe and has the potentiality, with his on-site and off-site effects, to affect water quality, food security and floods. Despite the implementation of numerous and different models for estimating soil erosion by water in Europe, there is still a lack of harmonization of assessment methodologies. Often, different approaches result in soil erosion rates significantly different. Even when the same model is applied to the same region the results may differ. This can be due to the way the model is implemented (i.e. with the selection of different algorithms when available) and/or to the use of datasets having different resolution or accuracy. Scientific computation is emerging as one of the central topic of the scientific method, for overcoming these problems there is thus the necessity to develop reproducible computational method where codes and data are available. The present study illustrates this approach. Using only public available datasets, we applied the Revised Universal Soil loss Equation (RUSLE) to locate the most sensitive areas to soil erosion by water in Europe. A significant effort was made for selecting the better simplified equations to be used when a strict application of the RUSLE model is not possible. In particular for the computation of the Rainfall Erosivity factor (R) the reproducible research paradigm was applied. The calculation of the R factor was implemented using public datasets and the GNU R language. An easily reproducible validation procedure based on measured precipitation time series was applied using MATLAB language. Designing the computational modelling architecture with the aim to ease as much as possible the future reuse of the model in analysing climate change scenarios is also a challenging goal of the research.

description: From 2017 to 2020, the Karlsruhe Institute of Technology, Department of Science Communication, together with Wissenschaft im Dialog and funded by the Robert Bosch Stiftung, implemented the project "Science for All" to systematically investigate which population groups have so far not or hardly been reached by science communication, why they are not reached and how this can be changed. The heterogeneity confirmed in a literature review and the diversity of groups not reached to date make it difficult to define them clearly. In most cases, an interplay of various exclusion factors (intersectionality) or, causally, their lack of or insufficient consideration by science communication leads to exclusion. Therefore, in order to systematize the research results in the present typology, the focus was placed on these factors rather than on social groups. The assignment of the factors to three levels is intended to provide a systematized overview, but should by no means be seen as an attribution of a deficit or a debt. In all cases, the responsibility for designing inclusive services lies with the scientific organizations. This hidden object graphic is aimed at stakeholders in science and science communication and is intended to stimulate understanding and reflection on all 31 exclusion factors identified in the project (factors marked with an * are overarching concepts of several other factors). The factors are assigned to the three categories formulated in the typology, but are freely distributed in the diagram. The visualizations show exemplary experiences of discrimination, diversity deficits and symbolic representations of structural problems. The image is supplemented by infographic elements that reflect selected statistical information.

description: In this paper we investigate the asymptotic validity of boundary layer theory. For a flow induced by a periodic row of point-vortices, we compare Prandtl's solution to Navier-Stokes solutions at different $Re$ numbers. We show how Prandtl's solution develops a finite time separation singularity. On the other hand Navier-Stokes solution is characterized by the presence of two kinds of viscous-inviscid interactions between the boundary layer and the outer flow. These interactions can be detected by the analysis of the enstrophy and of the pressure gradient on the wall. Moreover we apply the complex singularity tracking method to Prandtl and Navier-Stokes solutions and analyze the previous interactions from a different perspective.

description: We develop a general Ginzburg-Landau theory which describes the effect of a Zeeman field on the superconducting order parameter in triplet superconductors. Starting from Ginzburg-Landau theories that describe fully gapped time-reversal symmetric triplet superconductors, we show that the Zeeman field has dramatic effects on the topological properties of the superconductors. In particular, in the vicinity of a critical chemical potential separating two topologically distinct phases, it is possible to induce a phase transition to a topologically nontrivial phase which supports chiral edge modes. Moreover, for specific directions of the Zeeman field, we obtain nodal superconducting phases with an emerging chiral symmetry, and with Majorana flat bands at the edge. The Ginzburg-Landau theory is microscopically supported by a self-consistent mean-field theory of the doped Kitaev-Heisenberg model.

description: It is demonstrated, owing to the nonlinearity of QED, that a static charge placed in a strong magnetic field\ $B$\ is a magnetic dipole (besides remaining an electric monopole, as well). Its magnetic moment grows linearly with $B$ as long as the latter remains smaller than the characteristic value of $1.2\cdot 10^{13}\unit{G}$ but tends to a constant as $B$ exceeds that value. The force acting on a densely charged object by the dipole magnetic field of a neutron star is estimated.

We derive a precise orbital solution and the full physical properties of the system, including dynamical component mass estimates of 11.43+/-0.19 and 7.00+/-0.14 solar masses for the primary and secondary, respectively. Our frequency analysis reveals the rotation frequency of the primary in both the photometric and spectroscopic data and additional low-amplitude stochastic variability at low frequency in the space photometry with characteristics that are compatible with recent theoretical predictions for gravity-mode oscillations excited either by the convective core or by sub-surface convective layers. Doppler Imaging analysis of the silicon lines of the primary suggests the presence of two high-contrast stellar surface abundance spots which are located either at the same latitude or longitude. Comparison of the observed properties of the binary with present-day single-star evolutionary models shows that the latter are inadequate and lack a serious amount of near-core mixing.

description: Planck's data acquired during the first 15.4 months of observations towards both the disk and halo of the M31 galaxy are analyzed. We confirm the existence of a temperature asymmetry, previously detected by using the 7-year WMAP data, along the direction of the M31 rotation, therefore indicative of a Doppler-induced effect. The asymmetry extends up to about 10 degrees (about 130 kpc) from the M31 center. We also investigate the recent issue raised in Rubin and Loeb (2014) about the kinetic Sunyaev-Zeldovich effect from the diffuse hot gas in the Local Group, predicted to generate a hot spot of a few degrees size in the CMB maps in the direction of M31, where the free electron optical depth gets the maximum value. We also consider the issue whether in the opposite direction with respect to the M31 galaxy the same effect induces a minimum in temperature in the Planck's maps of the sky. We find that the Planck's data at 100 GHz show an effect even larger than that expected.

description: We investigate the scaling relation between the observed amount of absorption in the X-ray spectra of Gamma Ray Burst (GRB) afterglows and the absorber redshift. Through dedicated numerical simulations of an ideal instrument, we establish that this dependence has a power law shape with index 2.4. However, for real instruments, this value depends on their low energy cut-off, spectral resolution and on the detector spectral response in general. We thus provide appropriate scaling laws for specific instruments. Finally, we discuss the possibility to measure the absorber redshift from X-ray data alone. We find that 10^5-10^6 counts in the 0.3-10 keV band are needed to constrain the redshift with 10% accuracy. As a test case we discuss the XMM-Newton observation of GRB 090618 at z=0.54. We are able to recover the correct redshift of this burst with the expected accuracy.

FINANCIAL SECTOR LIBERALIZATION AND NIGERIA ECONOMIC GROWTH: A TIME-VARIANT STUDY
Creators: name: Ebube, C. Amadi
name: Ifeanyi, J. Wokocha
Publisher: name: AYDEN JOURNAL
Year: 2024
Subjects: Financial Sector Liberalization, Nigeria Economic Growth, Interest Rate Liberalization, Exchange Rate Liberalization

description: This study examined the relationship between financial sector liberalization and Nigeria economic growth. Time series data were sourced from Central Bank of Nigeria statistical bulletin from 19902023. Financial sector liberalization were proxy by savings rate liberalization, lending rate liberalization, exchange rate liberalization, capital market liberalization and current account liberalization while Nigeria economic growth was proxied by real gross domestic product. Multiple regressions with econometrics view statistical package were used as data analysis techniques. Co-integration, Granger Causality Test and Augmented Unit Root Test were used to determine the long and the short run relationship that exist among the variables. Findings of the study revealed that current account liberalization, capital market liberalization and lending rate liberalization have negative relationship with Nigeria economic growth while exchange rate liberalization, and savings rate liberalization have positive relationship with Nigeria economic growth. From the regression summary, the study conclude that financial sector liberalization have significant relationship with economic growth in Nigeria. We recommend that exchange rate deregulation should be deepened and the policies revisited to stimulate economic growth. Nigerian Interest rate liberalization such as lending, monetary policy rate and prime lending rate should be harmonized with the objective of economic growth. There should be policies to further deepen the operational effectiveness and effectiveness of the financial system for increase financial sector development. Implementable polices should be made to enhance Nigeria economic growth

description: The DIRHB package consists of three Fortran computer codes for the calculation of the ground-state properties of even-even atomic nuclei using the framework of relativistic self-consistent mean-field models. Each code corresponds to a particular choice of spatial symmetry: the DIRHBS, DIRHBZ and DIRHBT codes are used to calculate nuclei with spherical symmetry, axially symmetric quadrupole deformation, and triaxial quadrupole shapes, respectively. Reflection symmetry is assumed in all three cases. The latest relativistic nuclear energy density functionals are implemented in the codes, thus enabling efficient and accurate calculations over the entire nuclide chart.

To what extent can urbanisation mitigate the negative impact of population ageing in China?
Creators: name: Garcia Herrero, Alicia

description: Abstract
China is experiencing population ageing caused by a rapidly declining fertility rate and increased life expectancy. This demographic transition poses economic challenges, yet the intensity of these challenges depends on a number of factors, with the move of people from rural to urban areas being of central importance.
To gain a clearer understanding of how urbanisation interacts with population ageing, we investigate changes in the Chinese labour force in both rural and urban areas. Our findings suggest a modest shrinking of the overall labour force up until 2035. However, until 2035, the labour force is projected to contract only in rural areas, while the urban labour force will continue to grow. As urban employment is more productive than rural employment, the combined effect of demographic change and urbanisation on growth will remain moderately positive (0.4 percent per year).
Beyond 2035, fertility rate decline will begin to affect the working-age population in both rural and urban areas, especially since the urbanisation process is expected to level off by then. In such circumstances, China's shrinking population will shave off 1.4 percent from GDP growth annually. These results, however, do not take into account the impact of population aging on labour productivity. China's fast move towards robotisation and artificial intelligence might help mitigate any negative impacts by increasing productivity, but there is no sign yet that this is the case.
The Flow of Newtonian and power law fluids in elastic tubes

Year: 2014
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We derive analytical expressions for the flow of Newtonian and power law fluids in elastic circularly-symmetric tubes based on a lubrication approximation where the flow velocity profile at each cross section is assumed to have its axially-dependent characteristic shape for the given rheology and cross sectional size. Two pressure-area constitutive elastic relations for the tube elastic response are used in these derivations. We demonstrate the validity of the derived equations by observing qualitatively correct trends in general and quantitatively valid asymptotic convergence to limiting cases. The Newtonian formulae are compared to similar formulae derived previously from a one-dimensional version of the Navier-Stokes equations.

description: We derive generalized Langevin equations for the translational and rotational motion of a heated Brownian particle from the fluctuating hydrodynamics of its non-isothermal solvent. The temperature gradient around the particle couples to the hydrodynamic modes excited by the particle itself so that the resulting noise spectrum is governed by a frequency-dependent temperature. We show how the effective temperatures at which the article coordinates and (angular) velocities appear to be thermalized emerge from this central quantity.

description: Sphingolipids (SL) are well recognized for their cell signaling through extracellular and intracellular pathways. Based on chemistry different types of SL are biosynthesized in mammalian cells and have specific function in cellular activity. SL has an ampiphilic structure with have hydrophobic body attached to the polar head enables their use as a drug delivery agent in the form of nanocarriers. SL-based liposomes can improve the solubility of lipophilic drugs through host and drug complexes and are more stable than conventional liposomal formulations. Preclinical studies of SL nanocarriers are reported on topical delivery, oral delivery, ocular delivery, chemotherapeutic delivery, cardiovascular delivery and Alzheimer's disease. The commercial challenges and patents related to SL nanoformulations are highlighted in this article. Sphingolipids (SL) are well recognized for their cell signaling through extracellular and intracellular pathways. These regulatory lipids are responsible for angiogenesis regulation, and inflammatory responses and play a major role in metabolic diseases. They have an amphiphilic structure and hydrophobic bodies attached to polar heads enabling to encapsulation of both hydrophilic and hydrophobic drugs. Compared with the ester linkage in phosphatidylcholine SL has a benefit due to amide and ether bonding in structure which makes them more stable than conventional liposomes. SL-based nanocarriers are easily prepared by conventional passive, thin film hydration and mechanical dispersion methods. CER-based nanocarriers have shown efficacy in multiple solid and liquid cancer models. The short-chain CER-loaded liposomes for therapy of swelling of the frontal chamber showed therapeutic efficacy against inflammatory response in the eye. SL-based nanocarriers have also shown enhanced delivery of drugs to CNS and skin inflammatory diseases. SL-based nanofilm stents reduce cardiovascular hypertrophy compared with conventional stents. There are multiple patents of SL based nanocarriers used as drug delivery agent for ocular, topical and chemotherapeutics.
