Abstract
The paper analyses various time segments of a random process and shows how the covariance of the values of random functions for different times is displays. It is accepted that any type of management involves the optimal use of factors, avoiding the uncertainties that are inevitable with a statistical approach to the sequencing of scientific research. The model includes the risk minimization of the real process deviation from the anticipated one. The concept of the quasi-ergodic idea of two functions, which characterize this concept with the corresponding form of integrals, is important for a further understanding of the presented theory. Various time segment of a random process are analyzed during the scientific research, and it is shown how the covariance of random functions’ values for times is manifested. The proposed model allows us to expand the boundaries of the automation of the research management process in space and time, taking into account the risk associated with the use of factors of the digital model.

Analysis of interfacial behavior in two-phase flow using image processing
Authors: Digpriya  , Saini S , Banerjee J 
Published: May 2021

Abstract
Two-phase flow has a wide range of application from petroleum to space industry. Gas-liquid two-phase flow in horizontal pipe commonly occurs in petro-chemical, nuclear and geothermal industry, where simultaneously gas and liquid are transported through pipelines. During the transportation of gas-liquid flow simultaneously, due to the interaction of two phases, slug forms from the stratified-wavy flow. Slug flow consists of strong aeration at the slug front which is responsible for pipe failure and hazards in industries. Thus, it is required to understand the phenomena of slug formation in industrial pipeline to avoid the catastrophic pipe failure. In the present research, image processing technique is used to accurately analyze the interfacial behavior of two-phase flow. The interfacial behavior plays crucial role, as it is the plane where the two phases interact and interaction of the phases leads to the transition of different two-phase pattern. Experimentally captured images are processed using image processing algorithm, to study the variation of liquid film thickness. With the help of liquid film thickness transition of the interface is analyzed for different superficial Reynolds number of liquid and gas. Further, a PDF analysis is reported to understand the mechanism of the growth of the wavy interface.
Automated Product Inspection in Industry 4.0 Environment
Authors: Kiran M B 
Published: May 2021

Abstract
The emergence of Industry 4.0 technologies demands new techniques of measurement which would facilitate seamless integration with other devices in the wireless IoT network. Many of the existing product inspection methods cannot be deployed directly in the IoT environment. Thus, there is a need for innovative inspection techniques in the Industry 4.0 environment. In this context, the proposed inspection technique assumes special significance. Surface irregularities observed in product manufacturing can be due to chatter, vibration, worn-out cutting tools, condition of the machine tools, etc. Evaluation of surface texture helps in predicting a product’s functionality. In this work, an attempt has been made to identify the surface texture images acquired from Shaping, Milling, Electric discharge machining (E.D.M.) and Sand Blasting processes during online inspection. In addition to surface texture identification, the proposed method will also measure surface roughness and component dimensions. Thus, entire product inspection can be done online, and in a single setup. This is also an 100% online inspection method. The main contribution of this proposed research work is that all types of inspection are completed in a single set up, resulting in significant savings.

Published: May 2021

Abstract
The current research article deals with the fundamental characterization and carbon capture study of an indigenous activated carbon (AC) named MODISORB PL 4, derived from bituminous coal. Physical characterization to study the porous properties is carried out using N2 adsorption/desorption at 77 K on a 3 Flex Micromeritics Setup. The activated carbon sample has a BET surface area of 1213.016 m2/g, a pore volume of 0.285 cm3/g, and a pore size of 33.44 Å. The structural analysis carried out by powder XRD confirms the presence of graphite lattice in the adsorbent AC. The surface morphology is studied by FE-SEM analysis, which revealed that adsorbent activated carbon is microporous. The CO2 adsorption study is carried out for a relative pressure range of 0 to 1 and temperature varying from 298-333 K. The experimental data confirm the exothermic and physisorption behavior of the process. Isotherm models; Toth and Sips are fitted with the experimental CO2 adsorption data, in which both resulted in a good fit for the temperature and pressure range taken. The corresponding isotherm constants are illustrated in the article. Further, a comparison study is carried out with the existing literature to compare the CO2 uptake at ambient conditions, revealing that the assorted AC sample has immense potential for gas sorption, energy storage and carbon capture.

The single stage steam turbine for the SRC unit while the scroll expander for ORC unit is selected. Simulation of cascade RO system performance is considered using R245fa as a working fluid for ORC unit. The saturated steam from solar Scheffler disc will expand into steam turbine, where the reject heat from steam turbine will utilize for evaporation of ORC working fluid. The high-pressure RO pumps integrated with SRC and ORC turbines to provide net driving pressure to the RO module. This type of system is well suitable for desalination of brackish water due to moderate working temperature & pressure. Result shows that the pair of Rankine cycle will increase the overall (cascade) efficiency of the system. The basic input parameters are optimised with Taguchi approach. The performance of the system shows a good agreement with variation of mass flow rate of the steam in which the permeate flow rate from RO will increase along with the cycle efficiencies.

Published: May 2021

Abstract
Miscible nature of the material is vital to join dissimilar materials together. The wide range of properties within the single structure requires merging of multiple materials. Hence, sustainable welding technology development to join distinct material with extreme immiscibility such as Cu and SS is emerging as a recent research interest. Because of its requirement in nuclear reactors’ critical components, plan wave linac structures and ultra-high vacuum systems. Gas tungsten arc welding is a well-established commercial process. Hence, a study on optimum weld condition to get better quality of Cu to SS bimetallic joint is advantageous and desirable. However, complex flow nature of the molten Cu and SS is a big challenge. Hence, authors have reviewed and discussed the fluid flow of Cu and SS during gas tungsten arc welding. Which, concludes that the flow characteristics of Cu and SS must be studied through experimental and simulations to set up the favourable weld conditions while joining it with gas tungsten arc welding. The mentioned area of interdisciplinary research and not explored yet about the joint’s mechanical and microstructural properties. The said study can potentially predict what will be the final weld properties well before the metallurgical testing. Moreover, the article enlightens the interdisciplinary research aspect of Cu to SS bimetallic joining.

Abstract
Compression ignition (CI) engines are one of the promising power producing units which provide higher efficiency and durability. Increasing environmental pollution and depleting resources led the research in the field of alternative fuels such as biodiesels, ethanol etc. for utilization in CI engines. In the present study, two different types of biodiesels i.e. Jatropha Biodiesel (JBD), Used Cooking Oil (UCO) Biodiesel and Ethanol were investigated for the fuel properties and compared. Various fuel properties like density, kinematic viscosity, calorific value, oxidation stability, cold weather properties (CFPP, CF, and PP), and flash point temperature were measured and compared for pure form of alternative fuels. Different blends (5%, 10%, 15% and 20%) of JBD, UCO biodiesel and ethanol were also investigated. It has been observed that ethanol showed lower density, lower viscosity and superior cold weather properties compared to the tested fuels/blends. The average viscosity for ethanol was measured to be 1.08 mm2/sec which is ∼61.8 % less compared to mineral diesel. Oxidation stability tests were also performed where mineral diesel shows 83.15 min for 10% pressure drop at 140°C and 700 kPa, UCO biodiesel and JBD shows 9.2 min and 8.32 min. 5% ethanol blend showed sharp reduction in flash point compared to mineral diesel, however, it remained almost at the same level with further blending.

Published: May 2021

Abstract
In this work, the vapor absorption refrigeration system (VARS) with a cooling capacity of 1kW is designed. VARS is designed to be driven by hot water available from the solar thermal collector during the day. In the Sun’s absence, the system is designed to run by a coupled latent heat energy storage system. The unit has three major components: evacuated tube collector, latent heat energy storage, and VARS. The system is designed for a cooling capacity of 1 kW. The size of other components has been calculated by adopting the heat exchanger design approach and the relevant equations presented in the published works. The corresponding size of absorber, generator & condenser comes out to be 1.412kW, 1.46 kW & 0.96 kW, respectively for the cooling capacity of 1 kW. The evacuated tube collector of 100 LPD capacity is sufficient to provide the required heat to run the VARS and charge the thermal energy storage. Latent heat energy storage of 2.25 kW charging and discharging time of 3 hours kW is coupled with the system. The designed system gives the COP of 0.875.

Abstract

Objectives
We evaluated MYC and p53 expression, TP53 aberration, their relationship, and their impact on overall survival (OS) in acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL).

Methods
We identified 173 patients with ALL and LBL, including 12 cases of mixed-phenotype acute leukemia, 8 cases of therapy-related B-cell ALL (B-ALL), 119 cases of B-ALL, and 34 cases of T-cell ALL/LBL diagnosed from 2003 to 2019. We retrospectively assessed p53 and MYC expression by immunohistochemistry of bone marrow and correlated MYC expression with p53 expression and TP53 aberration.

Results
Expression of p53 and MYC was present in 11.5% and 27.7% of ALL/LBL cases (n = 20 and n = 48), respectively. MYC expression was significantly correlated with p53 expression and TP53 aberration (P = .002 and P = .03), and p53 expression and MYC expression had an adverse impact on OS in patients with ALL/LBL (P &lt; .05). MYC and p53 dual expression as well as combined MYC expression and TP53 aberration had a negative impact on OS in patients with ALL/LBL.

Conclusions
MYC expression is correlated with p53 overexpression, TP53 aberration, and poor OS in patients with ALL/LBL.

AbstractThe obstetrical conditions placenta accreta spectrum (PAS) and placenta previa are a significant source of pregnancy-associated morbidity and mortality, yet the specific molecular and cellular underpinnings of these conditions are not known. In this study, we identified misregulated gene expression patterns in tissues from placenta previa and percreta (the most extreme form of PAS) compared with control cases. By comparing this gene set with existing placental single-cell and bulk RNA-Seq datasets, we show that the upregulated genes predominantly mark extravillous trophoblasts. We performed immunofluorescence on several candidate molecules and found that PRG2 and AQPEP protein levels are upregulated in both the fetal membranes and the placental disk in both conditions. While this increased AQPEP expression remains restricted to trophoblasts, PRG2 is mislocalized and is found throughout the fetal membranes. Using a larger patient cohort with a diverse set of gestationally aged-matched controls, we validated PRG2 as a marker for both previa and PAS and AQPEP as a marker for only previa in the fetal membranes. Our findings suggest that the extraembryonic tissues surrounding the conceptus, including both the fetal membranes and the placental disk, harbor a signature of previa and PAS that is characteristic of EVTs and that may reflect increased trophoblast invasiveness.
Inequality and individuals’ social networks: the other face of social capital
Authors: Pena-López Atilano , Rungo Paolo , Sánchez-Santos José Manuel 
Published: May 2021

AbstractSocial capital is a controversial concept, which is used in economics as a generic form of pro-sociality and a simple means to introduce the social context into mainstream approaches. However, the accepted view underestimates social conflict and does not properly characterise social capital as an asset. When considering these issues, a different face of social capital emerges, one that can be associated with closure and privilege maintenance. This paper studies how access to and the extraction of social network resources depend on the social structure. By analysing data from a survey that included a position and a resource generator, we find that for the case of Spanish society, people endowed with high levels of economic and human capital enjoy improved accessibility and networks with a high prevalence of instrumental relations. There is essential inequality in the endowment of social capital, which augments economic inequality. When inequality is socially embedded, traditional redistributive policies may have limited effectiveness.
Domar, expectations, and growth stabilization
Authors: Boianovsky Mauro 
Published: May 2021

Abstract
Evsey Domar investigated in the 1940s the implementation of growth stabilization policy under the assumption that policy makers and businessmen alike believed his theoretical growth model. Economic policy was supposed to work merely through the impact of its announcement on expectations. He claimed that confident expectations, generated by government’s assurance of future growth through fiscal policy, would induce private investment decisions in a scale that would bring about the required growth rate and by that justify the expectations, without putting the guarantee to test. Domar’s policy framework contrasts with the policy-ineffectiveness proposition of New Classical macroeconomics advanced in the 1970s. Domar’s stabilization plan is discussed in detail in the context of his growth model, together with similar ideas put forward by Roy Harrod, as the latter modified aspects of his original growth model, and critical reactions by Alvin Hansen.
