Published: January 2023

The features of a new global economy appear stronger and faster than the changes recorded by the economy throughout history, and the “Covid-19” pandemic has accelerated these transformations, achieving on the ground a global experience to deal with digital payment via credit cards and the use of online payment applications, and it marks the beginning of the end of the era of paper currencies. And the trend towards investing in crypto and digital currencies on the part of investors, in conjunction with the competition of countries around the world to win the issuance of the first digital currency issued by central banks. There are many questions about replacing the digital currency with gold or the dollar in a rapid transformation that changes the trends of the global economy, and the number of cryptocurrencies around the world has reached about 4337 currencies with a market value of $ 1.003 trillion, “Bitcoin” holds the largest share by 66% with a market value of $ 664 billion. Despite many official warnings against investing in these unregulated currencies, fintech startups are witnessing a surge in demand from consumers who are rushing to invest in cryptocurrencies amid great interest and momentum in Bitcoin. Like Revolut, eToro and Luno, cryptocurrency demand surged on their platforms amid the resurgence of Bitcoin prices.

From a patient compliance perspective, solid oral dosages have a clear and acceptable precedence and, therefore, term and to be the favored route of administration. Tablets and capsules are widely manufactured and prescribed and provide several advantages over other dosage forms such as ease of storage, portability, straight, composite, administration, and accuracy in dosing. Multiple aspects (such as the selecting the same type of dosage form, excipients, compatibility of the drug with the excipient. Composition, manufacture ability, impact on bio availability, etc.) need to be considered while developing the drug product’s formulation. Relatively simply, formulation development can be considered an amalgamation and incorporation of core concepts in chemistry, pharmacokinetics, engineering technologies, and manufacturing practices to produce a product that is bio available, stable, manufacturable, and economically feasible.

Authors: Menezes Rachael , Deeney Megan , Wrottesley Stephanie V. , Lelijveld Natasha
Published: January 2023

Aims: This review aims to summarize available literature on the nutritional status of school-age children (SAC) and adolescents aged 5-19 years in Eastern and Southern Africa (ESA) and interventions aiming to tackle malnutrition in this age group. Methods: We searched Pubmed, Cochrane Database of Systematic Reviews, Web of Science, Africa Wide Information, ArticleFirst, Biomed Central, BioOne, BIOSIS, CINAHL, EBSCOHost, JSTOR, ProQuest, Google Scholar, SAGE Reference Online, Scopus, ScienceDirect, SpringerLink, Taylor & Francis, and Wiley Online for articles published between 2005 and 2020 according to eligibility criteria. Results: A total of 129 articles were included, with the majority of studies presenting data from Ethiopia (N = 46) and South Africa (N=38). The prevalence of overweight and obesity ranged between 9.1 – 32.3 % and 0.8 – 21.7 % respectively across countries in ESA. Prevalence of thinness, stunting and underweight ranged as follows: 3.0 – 36.8 %; 6.6 – 57.0 %; 5.8 – 27.1 %. Prevalence of anemia was between 13.0 – 76.9 % across the region. There was a dearth of data on other micronutrient deficiencies. There was limited evidence from intervention studies (N = 6), with half of the interventions targeting anemia or iron deficiency using iron supplementation or fortification methods and reporting no significant effect on anemia prevalence. Interventions targeting stunting and thinness (N = 3) reported beneficial effects of providing vitamin A fortified maize, iron supplementation and nutrition education. Conclusions: A triple burden of malnutrition underlines the need to prioritize implementation of double-duty interventions for SAC and adolescents in ESA. Key data gaps included either limited or a lack of data for the majority of countries, especially on micronutrient deficiencies and a scarcity of intervention studies. Greater investment in nutrition research amongst this population is needed to strengthen the evidence base and inform policies and programs to improve nutritional status amongst SAC and adolescents in ESA.

Keywords. Adolescence, overnutrition, undernutrition, micronutrient deficiencies, Interventions.

Published: January 2023

Abstract. Water-soluble humic-like substances (HULIS) absorb light in near-UV and
visible wavelengths and exert significant influence on the atmospheric
environment and climate. However, knowledge on HULIS evolution during haze
bloom-decay process is limited. Herein, PM2.5 samples were
obtained during a winter haze event in Guangzhou, China, and the light
absorption and molecular composition of HULIS were investigated by UV–Vis
spectrophotometry and ultrahigh-resolution mass spectrometry. Compared with
HULIS on clean days, the absorption coefficients (Abs365) of HULIS on
haze days were significantly higher but the mass absorption efficiencies
(MAE365) were relatively low, suggesting diverse and dynamic
absorption properties of HULIS during haze episodes. The CHO and CHON
compounds were the most abundant components in HULIS, followed by CHOS,
CHONS, and CHN. Haze HULIS presented comparatively high molecular weight; a
lower aromaticity index (AImod); and higher O/Cw, O/Nw, and
O/Sw ratios, indicating that HULIS fractions undergo relatively high
oxidation during haze days compared to clean days. Moreover, CHON and CHO compounds
with high AImod were the major potential chromophores in HULIS and
significantly contributed to HULIS light absorption. It is worth noting that
the proportions of these chromophores decreased during haze events,
mainly owing to their higher oxidation during haze episodes. Besides,
accumulated contribution of organic compounds emitted from vehicles and
formed from reactions of biogenic volatile organic compounds (bio-VOCs) also diluted light-absorbing compounds in
haze HULIS. These findings help us to understand HULIS evolution during haze
bloom-decay processes in the subtropic region of China.
Atmospheric response to wintertime Tibetan Plateau cold bias in climate models
Authors: Portal Alice , D'Andrea Fabio , Davini Paolo , Hamouda Mostafa E. , Pasquero Claudia
Published: January 2023

Abstract. Central Asia orography sets important features of the winter climate over East Asia and the Pacific. By deflecting the mid-latitude jet polewards it contributes to the formation of the Siberian High and, on the lee side, to the advection of dry cold continental air over the East Asian coast and the Pacific Ocean, where atmospheric instability and cyclogenesis thrive. While the mechanical forcing by the orography is assessed by a number of modelling studies, it is still not clear how near-surface temperature over the two most prominent orographic barriers of the Central Asian continent, namely the Tibetan and Mongolian plateaux, influences the winter climate downstream. Moreover, a well known issue of state-of-the art climate models is a cold land temperature bias over the Tibetan Plateau related with the difficulty in modelling land processes and land–atmosphere interaction over complex orography. Here we take advantage of the large spread in representing near surface temperature over the Central Asia plateaux among climate models taking part in the Coupled Model Inter-comparison Project, Phase 6 (CMIP6) to study how temperatures over these regions impact the atmospheric circulation. Based on composites of the CMIP6 models' climatologies showing a cold bias over the Tibetan Plateau, we find that negative temperature anomalies over Asian orography intensify the East Asia winter monsoon and, by enhancing the low-level baroclinicity in the region of the East China Sea, reinforce the southern flank of the Pacific jet. The results of the CMIP6 composite analysis are supported by the response of an intermediate-complexity atmospheric model to a similar pattern of cold surface temperatures over the Central Asia plateaux; we also distinguish the relative influence of the Tibetan and the Mongolian Plateau surface conditions. Thereby, based on the intensification of the East Asia winter monsoon in models characterised by a cold land temperature (bias) over Central Asia plateaux, we prospect that advances in the modelling of the land energy budget over this region may improve the simulation of the mean climate over the Asia/Pacific sector, together with the reliability of climate projections and the performance of shorter term forecasts.
Simulation of crop yield using the global hydrological model H08 (crp.v1)
Authors: Ai Zhipin , Hanasaki Naota
Published: January 2023

Abstract. Food and water are essential for life. A better understanding of the food–water nexus requires the development of an integrated model that can simultaneously simulate food production and the requirements and availability of water resources. H08 is a global hydrological model that considers human water use and management (e.g., reservoir operation and crop irrigation). Although a crop growth sub-model has been included in H08 to estimate the global crop-specific calendar, its performance as a yield simulator is poor, mainly because a globally uniform parameter set was used for each crop type. Here, through country-wise parameter calibration and algorithm improvement, we enhanced H08 to simulate the yields of four major staple crops: maize, wheat, rice, and soybean. The simulated crop yield was compared with the Food and Agriculture Organization (FAO) national yield statistics and the global data set of historical yield for major crops (GDHY) gridded yield estimates with respect to mean bias (across nations) and time series correlation (for individual nations). The improved simulations showed good consistency with FAO national yield. The mean biases of the major producer countries were considerably reduced to −4 %, 3 %, −1 %, and 1 % for maize, wheat, rice, and soybean, respectively. The corresponding coefficients of determination (R2) of the simulated and FAO statistical yield increased from 0.01 to 0.98, 0.21 to 0.99, 0.06 to 0.99, and 0.14 to 0.97 for maize, wheat, rice, and soybean, respectively; the corresponding root mean square error (RMSE) decreased from 7.1 to 1.1, 2.2 to 0.6, 2.7 to 0.5, 2.3 to 0.3 t/ha. Comparison with the reported performances of other mainstream global crop models revealed that our improved simulations have comparable ability to capture the temporal yield variability. The grid-level analysis showed that the improved simulations had similar capacity to GDHY yield, in terms of reproducing the temporal variation over a wide area, although substantial differences were observed in other places. Using the improved model, we confirmed that an earlier study on quantifying the contributions of irrigation on global food production can be reasonably reproduced. Overall, our improvements enabled H08 to estimate crop production and hydrology in a single framework, which will be beneficial for global food–water–land–energy nexus studies.
Scrutinizing and rooting the multiple anomalies of Nepal earthquake sequence in 2015 with the deviation–time–space criterion and homologous lithosphere–coversphere–atmosphere–ionosphere coupling physics

Published: January 2023

Abstract. The continuous increasing of Earth observations benefits geosciences and seismicity study but increases greatly the difficulties in understanding and discriminating multiple source data. Although the lithosphere–coversphere–atmosphere-ionosphere (LCAI) coupling paradigm and the deviation–time–space (DTS) criterion were presented for better searching for and understanding the potential seismic anomalies from multiple observations, the strict consistency of spatiotemporal characteristics and homologous physics of multiple-parameter seismic anomalies has not been investigated sufficiently. With the 2015 Nepal earthquake sequence being a typical case, the reported multi-parameter anomalies were systematically reviewed, and their space–time characteristics were summarized thoroughly in this study. Numerical simulation with refined geological structures in three-dimensional space revealed the inhomogeneous crustal stress field alteration (CSFA) along the faults and around the hypocenters of the 2015 Nepal earthquake sequence, which is expected to be the root of the seismic anomalies. The stress-activated positive charge carriers would have given rise to different responses near the ground surface (coversphere), including the microwave dielectric reduction, the additional infrared radiation, and the atmospheric ionization, which subsequently affected the physical properties of the atmosphere and the ionosphere and resulted in abnormal phenomena therein. Based on the DTS criterion and LCAI coupling paradigm, the seismic anomalies of the 2015 Nepal earthquakes were scrutinized strictly, and the retained anomalies were rooted carefully to the regional CSFA as well as its local blocking. Therefore, an integrated LCAI coupling framework with strict space–time correspondence and homologous physics in CSFA was proposed for the 2015 Nepal earthquake sequence. This research provides a definite philosophy as well as a practical solution for scrutinizing the rootable seismic anomalies from multi-parameter observations of earthquakes, which is of scientific meanings for searching earthquake precursors and reaching earthquake prediction.
Invited perspectives: An insurer's perspective on the knowns and unknowns in natural hazard risk modelling
Authors: Déroche Madeleine-Sophie
Published: January 2023

Abstract. This paper analyses how the current loss modelling framework that was developed in the 1990s to respond to Hurricane Andrew market crisis falls short in dealing with today's complexity. In effect, beyond reflecting and supporting the current understanding and knowledge of risks, data and models are used in the assessment of situations that have
not been experienced yet. To address this question, we considered the
(re)insurance market's current body of knowledge on natural hazard loss
modelling, the fruit of over 30 years of research conducted by (re)insurers,
brokers, modelling firms, and other private companies and academics in the
atmospheric sciences, geosciences, civil engineering studies, and data
sciences among others. Our study shows that to successfully manage the
complexity of the interactions between natural elements and the customer
ecosystem, it is essential that both private companies in the insurance
sector and academia continue working together to co-build and share common
data collection and modelling. This paper (i) proves the need to conduct an
in-depth review of the existing loss modelling framework and (ii) makes it
clear that only a transdisciplinary effort will be up to the challenge of
building global loss models. These two factors are essential to capture the
interactions and increasing complexity of the three risk drivers – exposure, hazard, and vulnerability – thus enabling insurers to anticipate
and be equipped to face the far-ranging impacts of climate change and other
natural events.

A survey on fundamental physics of dusty plasma
Authors: Agarwal A. K.
Published: January 2023

Two omnipresent ingredients of the Universe are plasmas and charged dust. The interplay between these two, dusty plasmas have opened up a new and fascinating research area. Dust turns out to be ubiquitous in cosmic plasmas, planetary plasmas, plasmas near the earth and plasmas in the laboratory. In fact, one may speculate that except in the hottest regions of fusion plasmas where dust particles would not survive, most plasmas are dusty plasmas in the sense that some dust particles may be present. Thus dusty plasmas play a vital role in wide range of phenomenon and are of current research interest for a number of reasons. Despite the fundamental study they also have relevance to fusion plasmas. It is an unavoidable problem that the plasma in a Tokomak is contaminated by scrape-off from the walls (thus these plasmas are inherently „dusty‟). Thus control and elimination of the dust produced is an important problem. Thus dusty plasma physics is one of the most rapidly growing and truly interdisciplinary fields of science, as indicated by the number of published papers in research journals and conference proceedings. Dusty plasma physics finds potential application in understanding not only astrophysical phenomenon like dust clusters, star formation, instabilities of interstellar molecular etc but also in the planetary magnetospheres of our solar system. Laboratory dusty plasma is used as a role model to understand these entire phenomena. In this paper, the basic physics of dusty plasmas is discussed. The main focus is on theoretical and experimental observations of dust charging processes, associated forces, crystallization, waves, the dynamics of rotating dust grains and scattering.

Published: January 2023

Appropriate soil water level is a necessary pre-requisite for optimum plant growth. Also, water being an essential element for life sustenance, there is the necessity to avoid its undue usage. Irrigation is a dominant consumer of water. This calls for the need to regulate water supply for irrigation purposes. Fields should neither be over-irrigated nor under-irrigated. Over time, systems have been implemented towards realizing this objective of which automated processes are the most popular as they allow information to be collected at high frequency with less labor requirements. Bulk of the existing systems employ micro-processor based systems. These systems offer several technological advantages but are unaffordable, bulky, difficult to maintain and less accepted by the technologically unskilled workers in the rural scenario.

Published: January 2023

A power system at a given operating state and subjected to a given disturbance is voltage stable if the voltages near loads approach post-disturbance equilibrium values. by using the energy function that maps the energy variation of the system, the effect of the slow chance of the system is analyzed and thus the system’s energy level changes that the stored energy measure is an indicator of the closeness of the operating point to the instability region of the system. With constraints on data availability and for study of power system stability it is adequate to model the synchronous generator with field circuit and one equivalent damper on q-axis known as the model 1.1. This paper presents a systematic procedure for modelling and simulation of a single-machine infinite-bus power system installed with a thyristor controlled series compensator (TCSC) where the synchronous generator is represented by model 1.1, so that impact of TCSC on power system stability can be more reasonably evaluated.

This could be done in one way by increasing the efficiency. For the properties like strength, toughness, stiffness to weight ratio, good formability, good corrosion resistance and high machinability must be improved. This challenge could be accomplished by Hybrid Metal Matrix Composites. Hybrid Metal Matrix Composites (HMMCs) are one of the recent advanced materials having the properties of light weight, high specific strength, good wear resistance and low thermal expansion coefficient. These composites materials are extensibly used in structural, aerospace and automotive industries. MMCs are composed of metallic base material called matrix, which is reinforced with a hard ceramic or soft reinforcement. Hybrid MMCs are obtained by reinforcing the matrix alloy with more than one type of reinforcements having different properties. For example SiC could be used as hard ceramic reinforcement and Graphite as soft reinforcement. Thus this research paper is focused on the review of the fabrication and characterization of hybrid metal matrix with summarizing the recent developments covering Aluminium used in manufacturing process.
Level Determination of Self and Organisational Efficacy

Self-efficacy is a significant element in Albert Bandura’s social cognitive theory. According to Bandura, a strong self-efficacy belief enhances perceived human capability and well being to perform a particular task. It emerges through gradual acquisition of anticipatory judgmental skills, social and physical skills through experience. On the contrary, organisational efficacy (OE) is a generative capacity within an organisation to cope effectively with the needs, hurdles, problems, and opportunities it encounters within the business environment. Organisational efficacy differs from self-efficacy because it is a group-level, as opposed to an individual level. The study includes 782 respondents from different pharmaceutical companies across different hierarchy level of various functional areas. The collected sample of the study varied widely on personal characteristics of the respondents. The result reveals that majority of the respondents possess high level of self and organisational efficacy. But respondents from age group 20-30 years are found to be having more efficacious beliefs.

Energy consumption in world is now increasing substantially. Increasing scarcity and rising prices of fossil fuels may lead to economic instability. Continuously increasing in energy consumption will overloads the distribution grids as well as the power stations, therefore imposing a negative impact on power availability, security and quality. One of the solutions for overcoming this is use of renewable energy resources. The energy generation from PV based Grid-Tied System is highly intermittent in nature and shows wide variation because of continuous fluctuations in solar radiation intensity, temperature and unpredictable weather conditions (e.g. clouds, snow, wind, etc.). This poses a major challenge for the designers of grid connected PV systems for its applications. One of the major problems is the increase in the Total Harmonic Distortion (THD) of current injected into the grid. In this paper basic theory of grid connected photovoltaic system and proposes a new scheme for Total Harmonic Distortion (THD) improvement in grid connected Photovoltaic (PV) systems. A hysteresis current control method is introduced in this paper which is providing a PV system with reduced harmonics at the output. This Logic control can be used to improve the THD in grid connected PV systems. The whole system is modeled on MATLAB/SIMULINK. The Simulation results are given to show the overall system performance.

Published: January 2023

This paper investigates the parameters affecting the friction stir processed copper and enhancement of the mechanical properties of the composite material. The results showed that the grain size of fabricated composite reduce, also it is indicated that in comparison to base metal (copper) micro hardness of friction stir processed composites in stir zone (SZ) increase significantly. The results obtained also indicated that the selected FSP parameters significantly influence the area of surface composite by the distribution of material particles. Higher tool rotational speed and lower processing speed produce an excellent distribution of material particles and higher area of surface composite due to higher frictional heat, increased stirring and material transportation.

The selection of machining parameters is one of the most important aspects in the electrical discharge machining operation as these conditions has important effect on material removal rate (MRR). In this paper the experiments were conducted on the machining of EN 31 die steel with graphite electrode with electrical discharge machining (EDM). The EDM oil commercial grade has been used as dielectric fluid. The effect of various EDM parameters such as discharge current, Ton and Toff has been investigated to yield the response in terms of MRR. In this work mathematical models have been developed for relating the MRR with machining parameters like discharge current, Ton, and Toff. The optimum value has been determined with the help of main effect plot and ANOVA table.

Effect of Heat Source on Mixed Convection of Non-Newtonian Fluids through Porous Medium along A Heated Vertical Flat Plate
Authors: Agarwal P. K. , Dwivedi Yogendra Kumar
Published: January 2023

The present paper is to study of an effect of heat source on mixed convective heat transfer of non-Newtonian fluids through porous medium on a flat plate has been investigated using a modified power – law viscosity model. This model does not contain physically unrealistic limits of zero or infinite viscosity as are encountered in the boundary - layer formulation with traditional models of viscosity for power – law fluids through porous medium with magnetic field. These unrealistic limits can introduce an irremovable singularity at the leading edge; The present modified model matches well with the measurement of viscosity, and does not introduce irremovable singularities. Therefore, the boundary layer equations can be solved by marching from the leading edge downstream as for Newtonian fluids. The numerical results are presented for a shear-thinning fluid in terms of the velocity and temperature distribution, and for important physical properties, namely the wall shear stress and heat transfer rates.
