Published: August 2020

Objective This study aimed to assess whether the hospital level of care where asphyxiated neonates treated with hypothermia were originally born influences their outcome.
Study Design We conducted a retrospective cohort study of all asphyxiated neonates treated with hypothermia in a large metropolitan area. Birth hospitals were categorized based on provincially predefined levels of care. Primary outcome was defined as death and/or brain injury on brain magnetic resonance imaging (adverse outcome) and was compared according to the hospital level of care.
Results The overall incidence of asphyxiated neonates treated with hypothermia significantly decreased as hospital level of care increased: 1 per 1,000 live births (109/114,627) in level I units; 0.9 per 1,000 live births (73/84,890) in level II units; and 0.7 per 1,000 live births (51/71,093) in level III units (p < 0.001). The rate of emergent cesarean sections and the initial pH within the first hour of life were significantly lower in level I and level II units compared with level III units (respectively, p < 0.001 and p = 0.002). In a multivariable analysis adjusting for the rates of emergent cesarean sections and initial pH within the first hour of life, being born in level I units was confirmed as an independent predictor of adverse outcome (adjusted odds ratio [OR] level I vs. level III 95% confidence interval [CI]: 2.13 [1.02–4.43], p = 0.04) and brain injury (adjusted OR level I vs. level III 95% CI: 2.41 [1.12–5.22], p = 0.02).
Conclusion Asphyxiated neonates born in level I units and transferred for hypothermia treatment were less often born by emergent cesarean sections, had worse pH values within the first hour of life, and had a higher incidence of adverse outcome and brain injury compared with neonates born in level III units. Further work is needed to optimize the initial management of these neonates to improve outcomes, regardless of the location of their hospital of birth.
Key Points
The myth of the ‘book famine’ in African publishing
Authors: le Roux Elizabeth 
Published: August 2020

ABSTRACT
The publishing industry in Africa is usually described in terms of ‘booklessness’, ‘hunger’ or ‘famine’. But does this language of scarcity reflect the realities of book production and consumption? In this paper, the concept of ‘book famine’ is analysed as a central frame of discourse on African books, using a survey of existing documentation. Two ways of responding to book famine – provision and production – are identified, and the shortcomings of book aid (provision) are contrasted with strengthening local publishing industries (production). It is argued that the concept has become a cliché that is no longer relevant and that African publishing, while variable, is responding to local needs.

Published: August 2020

Abstract
We apply particle based kinetic simulations to explore the characteristics of a low-pressure gas discharge driven by high-voltage (∼kV) pulses with alternating polarity, with a duty cycle of ≈ 1% and a repetition rate of 5 kHz. The computations allow tracing the spatio-temporal development of several discharge characteristics, the potential and electric field distributions, charged particle densities and fluxes, the mean ion energy at the electrode surfaces, etc. As such discharges have important surface processing applications, e.g. in the treatment of artificial bones, we analyse the time-dependence of the flux and the mean energy of the ions reaching the electrode surfaces, which can be both conducting and dielectric. Our investigations are conducted for argon buffer gas in the 40–140 Pa pressure range, for 1–5 cm electrode gaps and voltage pulse amplitudes ranging between 600 V and 1200 V.
Micro-actuation design in VO2-based bimorph cantilevers
Authors: Craciunescu Corneliu M , Kohl Manfred , Ercuta Aurel 
Published: August 2020

Abstract
The temperature-dependent actuation of cantilever-type bimorphs based on VO2 active layers exhibiting a reversible phase transformation (known as the ‘metal-to-insulator transition’ (MIT)) between a semiconducting monoclinic phase, and a metallic tetragonal (rutile) phase, can be optimized for specific applications by convenient selection of several parameters, among which the nature of the passive layer material, the cantilever geometry (layers thickness, beam length), and also the deposition temperature (at which the active and passive layers are joined), or the temperature at which the as-manufactured bimorph is annealed (in both cases the curvature being zero), are of special importance. In this sense, a model for the thermally controlled actuation of such bimorphs, in which the thermo-elastic parameters of the two layers materials, and also the evolution of these parameters during the phase transformation are taken into account, has been developed. The analysis projects significant differences in the actuation, in terms of the deposition temperature position relative to the thermal range of the phase transformation in the active layer. The model is useful in predicting the profile of the temperature-controlled actuation for custom-engineered devices based on this transformation. Nevertheless, the model provides a very useful tool for the design of experiments and actuators based on such MIT bimorphs.

Abstract
Designing exotic structures in low dimensions is key in today’s quest to tailor novel quantum states in materials with unique symmetries. Particularly intriguing materials in this regard are low dimensional aperiodic structures with non-conventional symmetries that are otherwise forbidden in translation symmetric crystals. In our work, we focus on the link between the structural and electronic properties of aperiodically ordered aromatic molecules on a quasicrystalline surface, which has largely been neglected so far. As an exemplary case, we investigate the self-assembly and the interfacial electronic properties of the nano-graphene-like molecule coronene on the bulk truncated icosahedral (i) Al–Pd–Mn quasicrystalline surface using multiple surface sensitive techniques. We find an aperiodically ordered coronene monolayer (ML) film on the i-Al–Pd–Mn surface that is characterized by the same local motifs of the P1 Penrose tiling model as the bare i-Al–Pd–Mn surface. The electronic valence band structure of the coronene/i-Al–Pd–Mn system is characterized by the pseudogap of thebare i-Al–Pd–Mn, which persists the adsorption of coronene confirming the quasiperiodic nature of the interface. In addition, we find a newly formed interface state of partial molecular character that suggests an at least partial chemical interaction between the molecule and the quasicrystalline surface. We propose that this partial chemical molecule–surface interaction is responsible for imprinting the quasicrystalline order of the surface onto the molecular film.

Abstract
Radiative capture p + 13C →
14N + γ at energies of astrophysical interest is one of the important process in the CNO cycle. We focus the reader’s attention on the possibility of describing this reaction within the framework of a single-particle potential model even when the reaction has a resonant characteristic. The partial components of the astrophysical S-factor are calculated for electric dipole transition. The calculated value of S-factor is in good agreement with experimental data both at low and high energy from the resonance position.

Published: August 2020

Abstract
Large deformation of a cantilever beam is an eminent structural analysis and engineering problem. A non-linear differential equation governs the problem of large deformation of beams. It has many important applications scientific and engineering fields. It is quite intricate and complex to find a closed-form or an exact solution for such a problem. It is relatively easier to use analytic expressions for calculations than numerical or experimental analysis. Large deformation analysis has always been an active area of research for researchers. The main focus of this research is to implement a new method namely Differential Transformation Method (DTM) for non-linear beam problem analysis. DTM is quite reliable and efficient in giving an approximate analytical solution to beam problems. Moreover, it is a new application for DTM. Hence, the primary purpose of this work is to evaluate the utility of the method for solution of beam problem. DTM yields a 2-point boundary value problem. It is based Taylor’s series expansion. DTM helps to calculate the deflection angle and horizontal as well as vertical displacements of a cantilever beam, experiencing large deformation, in an explicit analytical form. Mathematical formulation code will be developed using MATLAB. Variation of rotation angle at free end will be analysed using different number of terms used and values of non-dimensional load “β”. Results of DTM prove the method to be quite effective and suitable for predicting solutions to non-linear beam problems. Therefore, DTM can be used for widespread applications for new, emerging and complex engineering problems.

Published: August 2020

Abstract
The work presented here proposes a method to rank the efficiency of the actuators and sensors for the attenuation of excited structural modes. Aeroelastic wing designed with multiple control surfaces and equipped with sensors at different locations is used as a test case. A unifying theme to this work is the application of Hankel Singular Values (HSV), an analytical approach applied to the experimental data conducted during the Ground Vibrational (GVT) and Wind Tunnel (WT) tests. Modal information gathered from experimental results is used to define actuator/sensor relationships, once the mode of interest is decided then the sensor and actuator location is determined to effectively cater the structural vibrations, it paves the way for the design of specific performance metrics. The research will add redundancy to the available set of instrumentation by paving the way for the dedicated use of control surface for the stable flight mechanics or flight dynamics instability. The results presented here are supported by Power Spectral Densities (PSD’s) and band pass filters.

Abstract
This paper presents isolated dc to dc converter. It has dual input followed by two cascaded multilevel H bridge inverter and rectifier. This topology reduces the no of switches and components. Hence the cost of inverter is reduced and complexity is decreased. This is a major advantage over conventional topologies. This topology uses two DC sources which are asymmetrical, because of that seven level output voltage is obtain on the primary side of the transformer and step-up voltage obtain across the load. Switching techniques are used for proper working on this isolated converter and hence fulfil the objective of reducing overvoltage and stress in semiconductor devices. Simulation results are obtained in PSIM software.

Published: August 2020

Abstract
In this article, a seven-level inverter powered by solar has been proposed to achieve a sinusoidal output voltage with high efficiency and enhanced power quality. This system consists of active inverter and flipped condenser clamping. It gives output voltage level of 2/3. By connecting the switched condenser branch in the front or back end series to the inverter output a seven-level output voltage wave shape can be obtained with ample non-work switching states to match the voltage of switching condensers. The consequence of the proposed method is validated using MATLAB SIMULINK for simulation. Comparing with conventional seven-level inverter topology, the proposed design used a minimal number of switches using a basic modulation process.

The basic principle of the Internet of Things is based on the integration of information networks to make people’s lives easier. In this way, the objects can connect to each other and share information. The development of the Internet of Things has triggered by technology. A smart grid is an electricity network based on digital technology that is used to supply electricity to consumers via two-way digital communication. This system allows for monitoring, analysis, control and communication within the supply chain to help improve efficiency, reduce energy consumption and cost, and maximize the transparency and reliability of the energy supply chain. The smart grid was introduced with the aim of overcoming the weaknesses of conventional electrical grids by using smart net meters. Smart Grid technologies contribute to manage IoT energy efficiently, which the present ones lack in the existing framework. The two-way communication between connected devices and hardware which can sense and respond to user demands makes the IOT smart grid better.

Authors: Vasantharaj S , Indra Gandhi V 
Published: August 2020

Abstract
The modernization of distribution grids developed the power systems towards the smart grid. The microgrid plays a vital role in an improving power systems area, which refers to the loads operated under an organized and synchronized way and the distributed energy resources. The microgrid, which is operated in “islanded” mode, should be connected to the main power grid, or it must be entirely off-grid. Bipolar hybrid microgrid feeds local loads with local resources because it consists of both DC and AC bus simultaneously. The converter, which is used for microgrid application, plays an important role, which is said to be Interlinking Converter (ILC). The lower order harmonics can be eliminated by these ILCs. By reducing the THD and increasing the dc-link voltage utilization SVM is used. In this paper, there will be an increase in system performance and great reliability with a fully automated system. There will be a decrease in switching losses, current ripple and THD of grid current by the use of a new switching modulation method, which is validated by the Matlab simulation results.

Published: August 2020

Abstract
In this work, Nd–Fe–B alloy powders are fabricated via high energy ball milling and their fracture behavior and magnetic properties are investigated at different milling times. The powder characteristics (particle shape, size, size distribution, and microstructure) and magnetic properties of the Nd–Fe–B alloys are systematically analyzed. The initial spherical Nd–Fe–B powder is cracked/crushed even after a short period of milling (30 s) due to the high impact energy generated during high energy ball milling. These randomly cracked polygonal-shaped powders are fragmented after 5 min of milling and converted to fine powders. Interestingly, the fine particles after milling for 5 min are conducive to agglomeration at longer milling times (20–60 min) and formed spherically-shaped agglomerated powder. Additionally, the sphericity of the powder increased to 92% by re-pulverization and agglomeration at 60 min. The milled powder shows the Nd2Fe14B phase, and the x-ray diffraction patterns exhibit peak broadening with increasing milling time, clearly confirming the powder refinement behavior by high energy ball milling. The magnetic properties of the milled powders are systematically investigated and their behavior is elucidated as a function of the milling time.

Authors: Peyvasteh Motahareh , Popov Alexey , Bykov Alexander , Meglinski Igor 
Published: August 2020

Abstract
Increasing concerns about adulterated meat encouraged industry looking for new non-invasive methods for rapid accurate meat quality assessment. Main meat chromophores (myoglobin, oxy-myoglobin, fat, water, collagen) are characterized by close comparable absorption in visible to near-infrared (NIR) spectral region. Therefore, structural and compositional variations in meat may lead to relative differences in the absorption of light. Utilizing typical fiber-optic probes and integrating sphere, a degradation of pork samples freshness was observed at room temperature referring to the relative changes in absorbance of main meat chromophores. The application of principal component analysis (PCA) used for examination of measured absorbance spectra revealed more detailed sub-stages of freshness, which are not observed by the conventional analysis of the reflectance spectra. The results show a great potential of the combined application of optical-NIR spectroscopy with complementary use of PCA approach for assessing meat quality and monitoring relative absorbance alternation of oxymyoglobin and myoglobin in visible, and fat, water, collagen in NIR spectral ranges.
