AbstractWith the aim to explore innovative tools for organ preservation, especially in marginal organs, we hereby describe a clinical trial of ex-vivo hypothermic oxygenated perfusion (HOPE) in the field of liver (LT) and kidney transplantation (KT) from Extended Criteria Donors (ECD) after brain death. A matched-case analysis of donor and recipient variables was developed: 10 HOPE-ECD livers and kidneys (HOPE-L and HOPE-K) were matched 1:3 with livers and kidneys preserved with static cold storage (SCS-L and SCS-K). HOPE and SCS groups resulted with similar basal characteristics, both for recipients and donors. Cumulative liver and kidney graft dysfunction were 10% (HOPE L-K) vs. 31.7%, in SCS group (p = 0.05). Primary non-function was 3.3% for SCS-L vs. 0% for HOPE-L. No primary non-function was reported in HOPE-K and SCS-K. Median peak aspartate aminotransferase within 7-days post-LT was significantly higher in SCS-L when compared to HOPE-L (637 vs.344 U/L, p = 0.007). Graft survival at 1-year post-transplant was 93.3% for SCS-L vs. 100% of HOPE-L and 90% for SCS-K vs. 100% of HOPE-K. Clinical outcomes support our hypothesis of machine perfusion being a safe and effective system to reduce ischemic preservation injuries in KT and in LT.

Published: April 2020

AbstractCell migration involves dynamic changes in cell shape. Intricate patterns of cell shape can be analyzed and classified using advanced shape descriptors, including spherical harmonics (SPHARM). Though SPHARM have been used to analyze and classify migrating cells, such classification did not exploit SPHARM spectra in their dynamics. Here, we examine whether additional information from dynamic SPHARM improves classification of cell migration patterns. We combine the static and dynamic SPHARM approach with a support-vector-machine classifier and compare their classification accuracies. We demonstrate that the dynamic SPHARM analysis classifies cell migration patterns more accurately than the static one for both synthetic and experimental data. Furthermore, by comparing the computed accuracies with that of a naive classifier, we can identify the experimental conditions and model parameters that significantly affect cell shape. This capability should – in the future – help to pinpoint factors that play an essential role in cell migration.

Published: April 2020

AbstractCarbon steel is strong primarily because of carbides with the most well-known one being θ-Fe3C type cementite. However, the formation mechanism of cementite remains unclear. In this study, a new metastable carbide formation mechanism was proposed as ω-Fe3C → ω′-Fe3C → θ′-Fe3C based on the transmission electron microscopy (TEM) observation. Results shown that in quenched high-carbon binary alloys, hexagonal ω-Fe3C fine particles are distributed in the martensite twinning boundary alone, while two metastable carbides (ω′ and θ′) coexist in the quenched pearlite. These two carbides both possess orthorhombic crystal structure with different lattice parameters (aθ′ = aω′ = aω = $$\sqrt{2}$$2aα-Fe = 4.033 Å, bθ′ = 2 × bω′ = 2 × cω = $$\sqrt{3}$$3aα-Fe = 4.94 Å, and cθ′ = cω′ = $$\sqrt{3}$$3aω = 6.986 Å for aα-Fe = 2.852 Å). The θ′ unit cell can be constructed simply by merging two ω′ unit cells together along its bω′ axis. Thus, the θ′ unit cell contains 12 Fe atoms and 4 C atoms, which in turn matches the composition and atomic number of the θ-Fe3C cementite unit cell. The proposed theory in combination with experimental results gives a new insight into the carbide formation mechanism in Fe-C martensite.

The first case of novel coronavirus disease of 2019 (COVID-19) caused by severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) was reported in November2019. The rapid progression to a global pandemic of COVID-19 has had profound medical, social, and economic consequences. Pregnant women and newborns represent a vulnerable population. However, the precise impact of this novel virus on the fetus and neonate remains uncertain. Appropriate protection of health care workers and newly born infants during and after delivery by a COVID-19 mother is essential. There is some disagreement among expert organizations on an optimal approach based on resource availability, surge volume, and potential risk of transmission. The manuscript outlines the precautions and steps to be taken before, during, and after resuscitation of a newborn born to a COVID-19 mother, including three optional variations of current standards involving shared-decision making with parents for perinatal management, resuscitation of the newborn, disposition, nutrition, and postdischarge care. The availability of resources may also drive the application of these guidelines. More evidence and research are needed to assess the risk of vertical and horizontal transmission of SARS-CoV-2 and its impact on fetal and neonatal outcomes.

ABSTRACT

Ecological restoration measures implemented in China have profoundly impacted vegetation NPP. This study aimed to estimate the effects of the land conversion and management measures on the grassland ecosystem in semi-arid regions. Land use data were employed from 2000 to 2015 to compare land conversion and coverage changes in Xilingol grassland. Then, the contributions of land conversion and management policies were quantified by assessing the difference between actual NPP and climate-induced NPP changes. The results indicated that the grassland area had a net loss of 534.42 km
2
, and the net area of increased vegetation coverage was 74,683.05 km
2
. Furthermore, the total NPP increased by 8,010.73 Gg C·yr
−1
(1 Gg = 10
9
g), of which the human activities, including grazing management measures (+6,809.40 Gg C·yr
−1
) and land conversion (45.72 Gg C·yr
−1
) contributed to 85.58% of the increase in NPP. Transformation from desert and farmland dominated grassland expansion and NPP increase, while urbanization and desertification caused large grassland reduction and NPP loss. The grazing management increased vegetation NPP in most regions except for some regions in the desert steppe and the farming-pastoral zone. Related policies should be further adjusted to strengthen the management of the desert steppe and farming-pastoral regions.
Interactive Multi Resolution 2D Cellular Automata Model for Tsunami Wave Propagation
Authors: Mohamed E Syed 
Published: April 2020

Abstract
Cellular automata models are powerful tools that offer outstanding amenability, flexibility and deliver accurate qualitative and quantitative behaviour of the complex phenomena. In this paper, we develop a multi-resolution discrete event of cellular space propagation model with multiple spatial resolution cells for predicting the rate of tsunami wave spread. Specifically, as the tsunami wave spreads along with the cellular space, cells close to the wave front becomes high resolution (smaller size) and cells far from the wave front change to lower resolution (large size). The spatial resolution of the cells dynamically and adaptively develops as the wave proceeds. The conceptual framework for the investigation of the simulation and early results are presented. A methodology that is both appropriate and able to throw light on such natural clarity is the challenge for investigation and decision making in unknown or dynamical environments.

Published: April 2020

AbstractThis paper analyses a chemostat model for microbial production by considering substrate inhibition and variable yield coefficient. The Andrews growth model is considered to describe the inhibitory effect of high substrate concentration towards the microbial growth. The dependency of product yield towards the substrate concentration also incorporated in the chemostat model. The stability and bifurcation analyses of the chemostat model are presented to investigate the dynamical behaviour of microbial in the chemostat and to identify the parameter region that generates oscillations in the chemostat. The steady state solutions and their stability are determined as a function of residence time. When the feed substrate concentration is adjusted to be more than 6.1 g/L, there exist a parameter range of residence time that improves the microbial production in the chemostat.

Published: April 2020

Abstract
This paper presents an approach for generating project risk membership function (MFS) based on experts’ estimates and α-level variations using simulations. The proposed algorithm employs combination of computer and mathematics application in the area of risk assessment. The determination of appropriate MFS plays a substantial role in the performance of a fuzzy system. Most of the discussions in the previous literature on MFS generated, the assumptions that the risks are outlooked from similar perspective of the experts. However, this would be unlikely true in the real life when there is more than one expert from different background and experience. Proposed simulation method focuses on characteristics of MFS as well as the fuzzy numbers generation incorporating uncertainties in the experts’ inputs. Furthermore, results of set of fuzzy numbers of triangular MFS generated is presented in the fuzzy probability distribution and fuzzy cumulative distribution functions.

Published: April 2020

Abstract
Microwave link operates at high frequency approximately 10 GHz and above, and it suffers from high attenuation in the tropical region due to high rain intensity. Therefore, a microwave designer should consider this effect in the design so that the link can be operated with good quality of service, high availability and reliability. This study is about analysis of rain fade in a tropical country, Comoros, where the rain intensity was considered from ITU-R Recommendation. This rain intensity was used to determine the rain fade for earth-to-satellite of links operating in this country at L, C, Ka, Ku and V bands in horizontal, vertical and circular for 0.001% to 1% of exceeded per year. From the analysis, it was found that the link has availability to work from 99.999% to 99% with least effects in all frequency bands at vertical polarization, except in V-band. At 99% of availability, it shows that B-PSK is the best technique for modulation to make the proposed link more reliable. To attain 10dB fade margin which allows the antenna to reach certain quality of services, the gain receiver, diameter and figure of merit were increased while the footprint was maximized. The outcome of this study will be useful resources to upgrade the availability and reliability of earth to satellite microwave link in Comoros.

Published: April 2020

AbstractFor the understanding of the neural regulation of homeostasis, reproduction and behaviors, elucidation of structure and function of neuropeptides is inevitable. A classical technique for peptide purification is the separation of peptidic extract from nervous tissue by the high-performance liquid chromatography, which was followed by screening of fractions with biological or immunological assays. Although this approach requires relatively large amount of tissues for extraction and the screening is time- consuming, we have identified more than 15 kinds of bioactive neuropeptides in the nervous tissue of a marine snail,Thais clavigera.The purified peptides include TEP (Thaisexcitatory peptide)-1/-2, FRFamide, WWamide and others. The molecular cloning of precursor for each neuropeptide demonstrated that structurally related peptides are aligned in tandem on most of the precursor proteins. To identify the peptides on the precursors, we conducted thede novosequencing of peptides with the nanoLC-Orbitrap-MS/MS analysis. It identified most of the neuropeptides found on the precursor proteins in the extract from 50 ofThais ganglia.Thus, this technique is suitable for the comprehensive identification of peptides from relatively small amount of tissues. However, several peptides that had been identified by the classical technique, such as APGWamide and leucokinin, were not identified, suggesting the limitation of this brand-new technique.

Published: April 2020

Abstract
Polyethylene glycol (PEG) coated maghemite nanoparticles were synthesized using precursor variation through sonication-calcination method. The precursor was manufactured from lathe waste digested using (a) HCl: HNO3, (b) H2SO4: HNO3, and (c) H2SO4: HCl solvents. Samples were characterized using XRD, FTIR, color reader, and SEM-EDX. The X-ray diffraction pattern shows that Rietveld Refinement confirmed only one single-phase assigned to magnetite (Fe3O4) after sonication, one single-phase assigned to maghemite (γ-Fe2O3) after calcination, and widened peaks indicating nano-sized particles. Fourier transform infrared (FTIR) spectroscopy measurements confirmed the bonding of PEG to the magnetite and maghemite nanoparticles. Color reader measurement denoted the highest brightness level was achieved using precursor A. SEM-EDX data shows that the distribution of γ-Fe2O3 particles was not uniform. There were impurities detected, one of which was silica.

Published: April 2020

Abstract
Waste management, including heavy metal removal through bioremediation, requires process optimization. One of the important processes in a modern method is bacterial immobilization intended to improve the performance of bioremediation. In this preliminary study, silica material from rice husk processed via sol-gel was used, and cellulose of Nata de Coco was incorporated in situ during gelling to give balanced surface properties of a porous matrix. The modified could hold bacteria such as Pseudomonas fluorescens to be immobilized for further use. Variation of contact time was done, while temperature and stirring speed were kept constant. Assessment of Pseudomonas fluorescens bioremediation activity was carried out in cadmium standard solution. The result showed that the optimum contact time of Pseudomonas fluorescens and silica matrices was achieved at 30 min contact time as 99.19% was embedded in the matrices. This system decreased 80% of heavy metal in solution. This result indicates the compatibility of silica-cellulose matrix in Pseudomonas fluorescens immobilization, as predicted for other types of bacteria as well.

Abstract
The aims of this study was to evaluate the response of groundnut promising lines grown in various environments. A number of 18 groundnut lines and 2 checked cultivars were grown in 3 different environments i.e. lowlands with heavy and loamy soil texture at Ngawi and Banyuwangi Districts, and dry alkaline soils at Tuban District. A randomized block design with three replicates was applied in each site. Each genotype was planted in a 2 m x 5 m plot size with plant spacing of 40 cm interrows x 10 cm intrarow, 1 seed/hole. The basal fertilizer of 250 kg/ha composite NPK Phonska was applied at planting time. Location (site), genotype as well as its interaction significantly influenced the growth and yield variables. Four lines gave good yields at all sites i.e. BK10/LG5-295-50, BK1/LG5-37-64, BK1/LG5-B13-29-6, and BK1/LG5-B13-6-1. These four lines were less stable with its average pod yields were 4.0 t, 4.0 t, 3.9 t, and 4.0 t dry pods/ha consecutevely. Those pod yields were equal that those of checked cultivars Katana 1 and Hypoma 1. Instead of producing high pod yields, those four lines are resistant to leaf spot and rust diseases, so are merit to be proposed as newly superior cultivars.
