Published: October 2022

Abstract
The objective of this research is to study numerical integral equation method (NIE) using five quadrature rules namely, composite midpoint rule, composite trapezoidal rule, composite Simpson’s rule, composite Boole’s rule and Gauss-Legendre rule for approximating the average run length on extended exponentially weighted moving average (extended EWMA) control chart for autoregressive process with explanatory variables when white noise follows an exponential distribution. Furthermore, the comparison on performance of classical EWMA and extended EWMA control chart had been conducted. The results show that extended EWMA control chart can detect changes quicklier than EWMA control chart for all conditions.

Published: October 2022

AbstractSmart (also called “intelligent”) buildings become more and more common in the world due to higher levels of comfort, which they offer. They are more expensive to build than transitional facilities, because of more advanced systems of heating, ventilation, air conditioning, lighting, BMS and etc. as well as typically higher requirements regarding their construction. The present paper is focused on the assessment of thermal insulation of the smart building “Energis” of Kielce University of Technology (Poland) using an infrared camera. The study has been performed both from the outside and the inside of the building and thermographic images have been obtained and analysed in detail. The measurements have been performed on the winter day, when the temperature difference between the outside and inside air was about 20K. The infrared images enabled to determine the performance of the thermal insulation, mostly of the walls – especially in the areas of joining various elements with each other. The study provides valuable information on the heat losses analysis in the smart buildings.

Abstract
Titanium alloys have limited application in friction and wear environments due to their low surface hardness and poor wear resistance. By preparing a coating that improves wear resistance and high temperature oxidation resistance on the surface of the titanium alloy, the wear and corrosion resistance of the titanium alloy can be significantly enhanced, thereby greatly broadening its application fields and reducing production costs. Starting from the process, this paper systematically explained the current research status of surface laser modification technology at home and abroad, discussed the existing problems and corresponding solutions, and predicted the future development trend of the technology.

Abstract
In order to recuperate the ultra-high purity xenon from
PandaX-4T dark matter detector to high-pressure gas cylinders in
emergency or at the end-of-run situation, a high speed ultra-high
purity xenon recuperation system is designed and developed. This
system includes a diaphragm pump, the heat management system, the
main recuperation pipeline, the reflux pipeline, the auxiliary
recuperation pipeline and the automatic control system. The liquid
xenon in the detector is vaporized by the heat management system,
and the gaseous xenon is compressed to 6 MPa at the flow rate of
200 standard litres per minute (SLPM) using the diaphragm
compressor. The high-pressure xenon is filled into 128 gas cylinders
via the main recuperation pipeline. During the recuperation, the low
pressure and temperature conditions of 2 ∼ 3 atmospheres and
178 ∼ 186.5 K in PandaX-4T dark matter detector are kept by
the cooperation of the main recuperation pipeline, reflux pipeline
and the auxiliary recuperation pipeline to guarantee the safety, and
the purity of the recuperated xenon gas is measured to ensure no
contamination happened. The development of the high speed ultra-high
purity xenon recuperation system is important for the operation of
large-scale dark matter detectors with the requirements of strict
temperature and pressure environment and low background.

Abstract
The incidence of highly aggressive pancreatic cancer is increasing across the globe and is projected to increase to 18.6% by 2050. The mortality rate for this form of cancer is very high and the 5 y relative survival rate is only about 9%–10%. The 3D pancreatic cancer microenvironment exerts a major influence on the poor survival rate. A key factor is the prevention of the penetration of the chemotherapeutic drugs in the three-dimensional (3D) microenvironment leading to the development of chemoresistance which is a major contributor to the survival rates. Hence, in vitro studies using 3D cultures represent a better approach to understand the effect of therapeutic formulations on the cancer cells when compared to conventional 2D cultures. In the present study, we have explored three different conditions for the development of a 3D pancreatic tumour spheroid model from MiaPaCa-2 and PanC1 cells cultured for 10 days using Matrigel matrix. This optimized spheroid model was employed to evaluate a multi-functional nanotheranostic system fabricated using chitosan nanoparticles co-encapsulated with the chemotherapeutic agent gemcitabine and gold-capped iron oxide nanoparticles for multimodal imaging. The effect of the single and multiple-dose regimens of the theranostic system on the viability of 3D spheroids formed from the two pancreatic cancer cell lines was studied. It was observed that the 3D tumour spheroids cultured for 10 days exhibited resistance towards free gemcitabine drug, unlike the 2D culture. The administration of the multifunctional nanotheranostic system on alternate days effectively reduced the cancer cell viability after five doses to about 20% when compared with other groups. The repeated doses of the nanotheranostic system were found to be more effective than the single dose. Cell line-based differences in internalization of the carrier was also reflected in their response to the nanocarrier with PanC1 showing better sensitivity to the treatment. In vivo studies revealed that the combination of gemcitabine and magnetic field induced hypothermia produced superior regression in cancer when compared with the chemotherapeutic agent alone by a combination of activating the pro-apoptotic pathway and heat-induced necrosis. Our results reveal that this multi-functional system holds promise to overcome the current challenges to treat pancreatic cancers.

Authors: Mishra Varun , Tiwari Chandni , Chauhan Rahul 
Published: October 2022

Abstract
We have used SCAPS-1D to do simulations on CuO based solar cells using ZnO, TiO2, CdS and ZnSe as buffer layers. The solar cell characteristics are analysed by varying different material properties. The CuO/ZnO based solar cell showed highest efficiency ~20%. The interface defect however impacts the efficiency of this solar cell significantly. The interface defect and buffer layer thickness has shown little impact on the TiO2 and ZnSe buffer layer based solar cell. Further, we have optimized the impact of absorber layer thickness, carrier concentration and absorber defect as well. The effect of buffer layer thickness and electron affinity has also been investigated. Further, we have tried to understand the effect of temperature on the performance of these solar cells. The increase in temperature has resulted in decreased efficiency attributing to increased recombination rate.

Published: October 2022

Abstract
It’s a lesser-known fact that the cigarette filter is made of cellulose acetate, a kind of non-biodegradable plastic and it takes almost 10 years for this ingredient to completely decompose. Cigarette smoking is on the rise throughout the world. Ever since tobacco smoking began there are both opponents and proponents for the same. Instead of getting into a discussion as to whether one should smoke or not; would like to focus on cigarette butts which a micro plastic that is harmful to the environment and needs to be disposed of in an appropriate manner to conserve the environment and human health. As the trend is today, cigarette smoking is on the increase. And in light of this event recycling cigarette butts give rise to a sustainable material.
This paper will cover how cigarette butts can be collected and recycled to tackle the unfriendly and unsightly remains of cigarettes after smoking.

Published: October 2022

AbstractDrinking water is a sole element of human life. The rapidly growing population is adding to the excessive demand for water. Increasing demand for drinking water is rising the over-exploitation of water. Raw water sources require water treatment with a high production capacity of treatment. Present research provides a case study of the water treatment plant of Kekri, Rajasthan, India. In these two water treatment plants water purification efficiency is good as compared to conventional water treatment plants. Adding poly aluminum Chloride as a coagulant increases water treatment efficiency. Many parts of the water treatment plant add coagulation-flocculation, filtration, and disinfection by using poly aluminum chloride. Two water treatment plants with the capacity of 142 MLD and 132 MLD are having the net purifying capacity to remove the turbidity and Color. In this research, it has been found that turbidity removal of 142 MLD and 132 MLD WTP was found about 83.4 and 74.1% respectively. Total dissolved solid of surface reservoir Bisalpur dam found within acceptable limits. Total dissolved solids in Bisalpur dam surface water such as Chloride, Fluoride, and Nitrates were found of 60 mg/l, 0.3 mg/l, and 2 mg/l respectively. The pH value of surface water was found of 7.90 and remains almost constant with the seasonal variation impact. Turbidity and color reduction were found within the acceptable limit according to Indian standard 10500-2012.

Published: October 2022

Abstract
This paper highlights the problems caused due to lack of planning in designing the building envelope for a building. In recent years, as construction technology advances, designers are focusing on decreasing the weight of buildings for high-rise constructions. Also, the trends in the market are to plan buildings with extensive use of mechanical ventilation systems. So, in this regard, a study was done to find out the symptoms that are found in such types of buildings by restoring to more mechanical ventilation. It is a structured questionnaire-based study to discover the common symptoms of sick building syndrome (SBS). The locations which we chose for the survey included mixed environments like Dry climate, humid climate, hot climate, etc. Regions such as Karad, Kolhapur, and Vita had dry climates, while areas like Lonavala, Mumbai, and Airoli, had humid climates. Commonly found symptoms affected by the occupants were headaches, difficulty breathing, and concentration. The most significant factors are dust, glare, and light. Also, complaints of hay fever were given by the occupants. Headache, Difficulties in concentration, fatigue and cough are the prominent factors observed in the three months by the occupants. So it can be concluded that the mechanical ventilation should be aided with good recovery of the natural air inflow. Also, location-wise climatic conditions should be considered when planning the ventilation systems.

Published: October 2022

Abstract
Currently, environmental pollution is a global issue that is directly or indirectly related to human activities. Uses of chemical fertilizer also cause long-term environmental pollution. Concerning this, the composting technique for the management of organic waste is a good deal. This method or technique is better than chemical fertilizers as it is eco-friendly and environmentally friendly. The use of compost depends on its different quality parameters. The presented study shows the comparative analysis of three types of compost which were prepared by windrow type of composting. Composts were differentiated based on their organic matter source. Analysis of compost quality was done based on their macronutrient – Nitrogen, Phosphorus, and Potassium and the physical composition of compost. The result shows that all three types of composts match the quality standard of the Indian Fertilizer Control Order-1985. Compost from vegetable waste contains more nutrients as compared to others. All three were very less different in their nutrient composition. By comparing the composting time duration fruit waste is converted into compost earlier than others. This shows that vegetable waste gives high-quality compost that can be used as organic fertilizer. Fruits and farm waste are also useful but vegetable wastes give better quality compost concerning macronutrients.

Abstract
The population living in areas rich in granites, minerals and soils with high concentrations of natural radionuclides is exposed to higher external radiation. Significant part of a person's time resides in buildings where he lives and works. The walls, floors and roofs of the buildings shield (weaken) the external gamma background. The aim of the work is to determine the content of natural radionuclides in rock and inorganic materials used as building materials of samples taken from different buildings in Southern Bulgaria by analysing the samples and measuring their natural radioactivity, then to compare the results with the maximum concentrations of activity in common building materials. also used in the EU.
The data obtained from the analyzes do not give grounds to expect the generation of radionuclides from natural and conventional inorganic building materials used in the studied areas.

Authors: Liu Zhenqiang , Tian Xue , Zhu Qizhen , Xu Bin 
Published: October 2022

Abstract
With high theoretical capacity and suitable operating potential, SiO
x
is regarded as one of the most promising anode materials for high-energy density lithium-ion batteries (LIBs), but it suffers from large volume change during charge/discharge and low electronic conductivity, leading to poor cycling stability and rate capability. To overcome these problems, a SiO
x
@ reduced graphene oxide (rGO) film with porous structure is prepared through vacuum filtration and self-propagation reduction method, which can be directly used as a free-standing anode for LIBs. The self-propagation process of graphene oxide to graphene can be completed rapidly within 1 s, and endows the film with developed pores due to the instantaneous release of substantial gases. The porous structure is beneficial for exposing massive active sites, facilitating fast ion transport and buffering the volume change of the SiO
x
during charge/discharge. Moreover, the rGO sheets construct a conductive framework for rapid electron transfer in the film. As a result, the SiO
x
@rGO film exhibits high lithium storage capacity (1189.7 mAh g−1 at 0.1 A g−1), excellent cycling stability (81.1% capacity retention after 100 cycles) and good rate capability (349.2 mAh g−1 at 3.2 A g−1). This study not only provides a high-performance film anode material for LIBs, but also develops a simple and efficient method for constructing porous film electrodes for various energy storage devices.
The random first-order transition theory of active glass in the high-activity regime

Published: October 2022

Abstract
Dense active matter, in the fluid or amorphous-solid form, has generated intense interest as a model for the dynamics inside living cells and multicellular systems. An extension of the random first-order transition theory (RFOT) to include activity was developed, whereby the activity of the individual particles was added to the free energy of the system in the form of the potential energy of an active particle, trapped by a harmonic potential that describes the effective confinement by the surrounding medium. This active-RFOT model was shown to successfully account for the dependence of the structural relaxation time in the active glass, extracted from simulations, as a function of the activity parameters: the magnitude of the active force (f
0) and its persistence time (τ

p
). However, significant deviations were found in the limit of large activity (large f
0 and/or τ

p
). Here we extend the active-RFOT model to high activity using an activity-dependent harmonic confining potential, which we solve self-consistently. The extended model predicts qualitative changes in the high activity regime, which agree with the results of simulations in both three-dimensional and two-dimensional models of active glass.
Sustainable biodiesel from flex-mix feedstock and its combustion in a VCR-CRDI engine with variable exhaust gas recirculation and injection pressure

Published: October 2022

Abstract
Biodiesel produced from single feedstocks has many challenges due to variations in the oil properties. The flex-mix approach is a long-term solution for turning mixed feedstock into high-quality biodiesels. In this investigation, a pre-mixed used cooking oil and animal fat (pig fat) mixture (from 20% to 80%) was transesterified to produce flex-mix methyl ester (FMME). The FMME fuel characteristics were tested and compared to biodiesel standards. Generally, biodiesel emits higher oxides of nitrogen (NO
x
) gas due to the presence of highly unsaturated compounds and oxygen. The present study aims to address this issue by adopting the flex-mix approach in combination with fuel injection strategies (400, 500 and 600 bar), exhaust gas recirculation (EGR 10%, 20% and 30%) and variable compression ratio (CR 17.5:1, 20:1 and 22:1). At a CR of 22 and an injection pressure (P
inj) of 600 bar, the FMME fuel without EGR shows a minimum reduction in brake thermal efficiency of 0.15% when compared to diesel. Nitric oxide gas emissions decreased by nearly 50% for all P
inj and EGR values, but they rose when the compression ratio was increased to 20 and 22. Smoke and hydrocarbon emissions also increased with the exhaust gas proportion. The engine performance with FMME fuel was found to be equivalent to that with fossil diesel fuel. According to the findings, the flex-mix approach could be a long-term alternative to producing renewable fuel for off-road diesel engine application.
A Translanguaging Perspective on Teacher Contingency in Hong Kong English Medium Instruction History Classrooms
Authors: Tai Kevin W H 
Published: October 2022

Abstract
A growing number of studies have explored the ways how teachers contingently respond to students’ unexpected responses or a lack of student responses in second language classrooms. From a sociocultural perspective, teacher contingency involves a departure from the lesson plan in local response to the unexpected or unforeseeable actions in the classroom interactions (van Lier, 2001). This study adopts translanguaging as an analytical perspective in order to examine how a teacher employs various resources to contingently respond to students’ initiatives and reformulate his utterances in order to prompt student participation. The data are based on a larger linguistic ethnographic project in a Hong Kong English-Medium-Instruction secondary history classroom. This paper reconceptualizes the notion of teacher contingency and argues that the process of how the teacher contingently responds to the unexpected outcomes that arise in real-time interactions is a process of translanguaging. Such a process requires the teacher in orchestrating the available linguistic and multimodal resources to construct pedagogical actions on the spot, instead of being planned in advance.

AbstractMotivationDifferentiating 12 stages of the mouse seminiferous epithelial cycle is vital towards understanding the dynamic spermatogenesis process. However, it is challenging since two adjacent spermatogenic stages are morphologically similar. Distinguishing Stages I–III from Stages IV–V is important for histologists to understand sperm development in wildtype mice and spermatogenic defects in infertile mice. To achieve this, we propose a novel pipeline for computerized spermatogenesis staging (CSS).ResultsThe CSS pipeline comprises four parts: (i) A seminiferous tubule segmentation model is developed to extract every single tubule; (ii) A multi-scale learning (MSL) model is developed to integrate local and global information of a seminiferous tubule to distinguish Stages I–V from Stages VI–XII; (iii) a multi-task learning (MTL) model is developed to segment the multiple testicular cells for Stages I–V without an exhaustive requirement for manual annotation; (iv) A set of 204D image-derived features is developed to discriminate Stages I–III from Stages IV–V by capturing cell-level and image-level representation. Experimental results suggest that the proposed MSL and MTL models outperform classic single-scale and single-task models when manual annotation is limited. In addition, the proposed image-derived features are discriminative between Stages I–III and Stages IV–V. In conclusion, the CSS pipeline can not only provide histologists with a solution to facilitate quantitative analysis for spermatogenesis stage identification but also help them to uncover novel computerized image-derived biomarkers.Availability and implementationhttps://github.com/jydada/CSS.Supplementary informationSupplementary data are available at Bioinformatics online.
