The pleiotropic actions of the Farnesoid X Receptor (FXR) are required for gut health, and reciprocally, reduced intestinal FXR signaling is seen in inflammatory bowel diseases (IBDs). Here, we show that activation of FXR selectively in the intestine is protective in inflammation-driven models of IBD. Prophylactic activation of FXR restored homeostatic levels of pro-inflammatory cytokines, most notably IL17. Importantly, these changes were attributed to FXR regulation of innate lymphoid cells (ILCs), with both the inflammation-driven increases in ILCs, and ILC3s in particular, and the induction of
Il17a
and
Il17f
in ILC3s blocked by FXR activation. Moreover, a population of ILC precursor-like cells increased with treatment, implicating FXR in the maturation/differentiation of ILC precursors. These findings identify FXR as an intrinsic regulator of intestinal ILCs and a potential therapeutic target in inflammatory intestinal diseases.

Abstract
The combined effects of the atomic-layer-deposition (ALD) temperature (220 °C–280 °C) and metal electrodes (TiN and Mo) on the ferroelectric properties of Hf0.5Zr0.5O2 films were studied. Regardless of the metal electrode, a tetragonal–orthorhombic–monoclinic phase evolution sequence was observed with increasing ALD temperature after post-metallization annealing. However, the phase transition temperature slightly changed depending on the metal electrode, which was predetermined based on the as-deposited states. Additionally, the out-of-plane orientation of the final orthorhombic grains was highly dependent on the crystallographic alignment of the metal electrode grains, resulting in different values of the maximum remanent polarization. In terms of long-term reliability, the fatigue characteristics were highly dependent on the electrode characteristics, and the wake-up characteristics were mainly affected by the initial phase distribution determined by both the ALD temperature and metal electrode.

Abstract

Objective. While the accuracy of dose calculations in water with Acuros XB is well established, experimental validation of dose in bone is limited. Acuros XB reports both dose-to-medium and dose-to-water, and these values differ in bone, but there are no reports of measurements of validation in bone. This work compares Acuros XB calculations to measurements of absolute dose in aluminum (medium similar to bone). The validity of using selected relative dosimeters in aluminum is also investigated. Approach. A calorimeter with an aluminum core embedded in an aluminum phantom was selected as bone surrogate for the measurement of absolute dose. Matching the medium of the core to the medium of the phantom allowed eliminating the calculation of the conversion between media. The dose was measured at the fixed depth of 3.3 cm in aluminum (∼9 g·cm−2) with 6X, 10X, 6FFF and 10FFF photon beams from a TrueBeam Varian linac. In addition, experimental cross-calibration between water and aluminum was performed for an IBA CC13 ionization chamber, a PTW microDiamond and EBT3 Gafchromic film. Main results. Calculations with Acuros XB dose-to-medium in aluminum differed from the calorimetry data by −2.8% to −3.5%, depending on the beam. Use of dose-to-water would have resulted in about 39% discrepancy. The cross calibration coefficient between water and aluminum yielded values of about 0.87 for the CC13 chamber, 0.91 for the microDiamond, and 0.88 for the film, and independent of the beam within about ±1%. Significance. It was demonstrated the value of the dose-to-medium in aluminum (surrogate of bone) computed with Acuros XB is close to the value of the absolute dose measured with a calorimeter, and there is a significant discrepancy when dose-to-water is used instead. The use of an ionization chamber, a microDiamond and Gafchromic film in aluminum required a considerable correction from calibration in water.
Spatial structure of a Bose–Einstein condensate in a combined trap*
Authors: Li Fei , He Zhijian , Li Wenwu 
Published: December 2022

Abstract
We study the spatial structure of a Bose–Einstein condensate (BEC) with a space-dependent s-wave scattering length in a combined trap. There exists a space-dependent nonlinear atomic current in the system. The atomic current has an important influence on the spatial structure of the BEC. Research findings reveal that a large chemical potential can effectively suppress the chaotic spatial structure in the BEC system. Due to the large chemical potential, a strong atomic current is necessary to make the system lose its periodic spatial structure and lead the system into a chaotic spatial structure. But when the atomic current intensity exceeds a critical value, the chaotic spatial structure of the BEC will be completely eliminated and the system will always be kept in a series of single-periodic states as the atomic current becomes stronger. For a very weak atomic current, the spatial structure of the BEC is very sensitive to the intensity of the atomic current and a very small change of the intensity can dramatically change the spatial structure of the BEC. The effects of the combined trap parameters on the spatial structure of BECs are also discussed.

Abstract
In a developing country like India faces a challenges in waste management, due to an exceptional population growth and expansion. Research related to the waste management shows that the increase in waste materials generated in cities are difficult to handle. The issues related to handle the waste material is due to improper collection and disposal of waste materials, the increase in population toward big cities and nonexistence of intelligent technology leads to the environmental pollution. Management of this waste materials has becoming a challenging task from small villages to big cities. Furthermore, the problems in handling the waste materials also involved due to the lack of labour involved. In this paper, an IoT based Solid waste management system using smart dustbins has been proposed. The developed system helps to solve the issues in managing the solid waste from small to large scale. An electronic based dustbin has been developed to indicate the level of waste in the bin, based on the levels of waste in the bin an alert system is used to indicate and collect the waste material from different places in the city. The system helps to monitor the waste materials in the electric bins and also helps to analysis the amount of waste produced at a particular location. The information related to the level of bins has been wireless transmitted to the central location for emptying the bins. The advantage of the system is to collect waste material on time in order to avoid the overflow of bins and also analysis the amount of waste produced at a particular location. The developed system helps to save the environment from pollution.

Abstract
Today, the world needs a substitute material for cement because the Co2 emission is high while the production of cement. This research presents the test results of the combined effect of eggshell powder (ESP) and sugarcane bagasse ash (SCBA) as a partial substitute for cement in concrete. It includes properties of the concrete in compressive strength, work efficiency and setting time. The utilization of poultry-industrial and agro-industrial waste in construction supports both material waste manipulation environmental protection. This research was carried out to determine the optimum replacement percentage of SCBA and ESP in concrete. It focuses on the behaviour of high-strength concrete with life analysis with SCBA and ESP as an alternative pozzolanic substance. SCBA added with a control ratio of 10%, 20%, 30% and ESP added with 5% in all mix proportions and the mechanical properties, the microstructure compared with control mix. Obtained for the two compounds and shows that 20% SCBA and 5% ESP replacement can be done to some extent to get the best output when compared to control mix results. Therefore, numerous tests were performed toward the samples, including the compression test, split tensile and flexure test. Based on previous research, the strength of concrete decreased as it was replaced with a higher replacement of eggshell powder. Partial replacement of SCBA and ESP in cement also helps to minimize environmental degradation.

The polymer concrete that we made consists of cement, coarse aggregate, fine aggregate, water, polymer resin. The polymer resin that we used is Master EmacoSBR2. It is a styrene butadience copolymer latex liquid, milky white, produced from styrene and butadience by high pressure emulsion polymerization with high dispresive properties. The polymer resin that replaces cement were 2.5Litre, 5Litre, 10Litre, 12.5 Litre for 50Kg cement. The polymer concrete with different mix proportions are compared with the normal concrete. The test results compared are further studied and the effective percentage of polymer resin to be added in concrete is given.
Seismic Assessment of Multistorey building of plan irregularity with varying A/L ratio (Re-entrants corners)
Authors: Balaji P Shanmugamani , Senthilpandian M 
Published: December 2022

Abstract
Buildings with re-entrant corners are used when maximum utilization is done over minimum available space. These re-entrant corners come under the plan irregularities of the structures. Plan irregularity (or) Vertical irregularity makes vulnerable under seismic loading. Structural irregularities are an important factor in that structure’s seismic performance structure. This study aims to gain the seismic behaviour of the building with an L-shape floor plan by checking the irregularity of re-entrant corners by seismic response demands that is been measured with varying A/L ratios. The response includes top floor displacement, interstory drift, Story Stiffness, and base shear. The study consists of 5 models with varying A/L ratios with 3 sub-divided models of various seismic positions of the shear wall (i.e.) a model without a shear wall, a model with a shear wall at the centre, a model with a shear wall at the periphery. 15 models are made for a clear study of the seismic behaviour and the effective position of the shear wall with varying A/L ratios. The models are analysed with ETABS using the Equivalent static method (ESL) and Response Spectrum (RS) methods. The results prove that the model with a lesser A/L ratio satisfies the analysis even without the shear wall excluding the lift RCC wall, whereas when the A/L ratio increases the model is effective only when the shear wall is provided at the periphery. Thus, the economical and effective seismic position of the shear wall is found with varying A/L ratios and satisfies the seismic demand for the structure. As the building with re-entrant corners are more vulnerable the building plan must be of regular configuration to possess significant seismic resistance.

Published: December 2022

Abstract
Nowadays, composite beams and columns were used as structural members for their higher strength and rigidity for load-carrying structures. Generally, the concrete-encased composite column has a compound section formed by the steel section and the surrounding concrete will be made by a composite. Based on the studies of steel encased concrete sections based on experimental and computational analysis over static and dynamic load cases shows advantages over the conventionally use structural steel or reinforced concrete in terms of ductility and shear resistance. The structure can experience static loads as well as fatigue loads in some situations. So the behavior of structural elements under differential loading should be obtained to design them effectively. A similar shape of the column section plays a key role in resisting lateral buckling under axial compression. This paper compares the behaviour of steel concrete composite sections by varying the shape and size for both concrete infilled and encased conditions based on the earlier research works.

Published: December 2022

Abstract
The research region, Kallipatti, is surrounded by coconut farms, coir pith companies, and other businesses, and people report that water has become their primary concern in the last three years. Skin and eye allergies, as well as lung and throat infections, have been on the rise. Coir pith degrades slowly and can be found in the soil for long periods of time. Coir pith is tenacious and accumulates in the environment, generating hillocks that pollute the environment in locations near coir fibre extraction plants. These units contribute significantly to the pollution of the environment, both on land and in the water. Coir pith is easily blown by the wind, causing pollution in the air. The leaching of tannin and salts from coir pith hillocks during monsoon rains pollutes ground water, which is detrimental to fisheries, animals, and humans because most of these pollutants are difficult to remove using waste treatment procedures. Because of the vast quantities of coir pith kept, leachates containing residual phenol from these landfills seep into the soil, thereby polluting it. and causes contamination of ground water, especially during the rainy season. It’s a great place for rats and other bug pests to breed. Despite the fact that coir pith is a hazardous waste, it can be turned into beneficial organic manure by microbial breakdown. Pollution sources are identified, soil samples are taken, physical properties of the soil samples are measured, and critical nutrients for crop growth such as nitrogen and soil OC (organic carbon) are examined in this study. These criteria should be evaluated to determine the health of the soil. The results are compared to IS code 1498-1970 (Soil classification and identification) and IS 2720-1985 (Methods of testing for soils).
Developing a care home data platform in Scotland: a mixed methods study of data routinely collected in care homes
Authors: Shenkin Susan D , Johnston Lucy , Hockley Jo , Henderson David A G 
Published: December 2022

Abstract

Background
care homes collect extensive data about their residents, and their care, in multiple ways, for multiple purposes. We aimed to (i) identify what data are routinely collected and (ii) collate care home managers’ views and experiences of collecting, using and sharing data.

Methods
we examined data collected in six care homes across Lothian, Scotland. We extracted the meta-data, cross-referenced definitions and assessed the degree of harmonisation between care homes and with data sets currently in use in Scotland and internationally. We interviewed care home managers about their views and experiences of collecting, using and sharing data.

Results
we identified 15 core data items used routinely, with significant heterogeneity in tools and assessments used, and very limited harmonisation. Two overarching themes were identified of importance to the development of a care home data platform: (i) the rationale for collecting data, including to (a) support person-centred care, (b) share information, (c) manage workforce and budget and (d) provide evidence to statutory bodies and (ii) the reality of collecting data, including data accuracy, and understanding data in context.

Discussion
considerable information is collected by care home staff, in varied formats, with heterogeneity of scope and definition, for range of reasons. We discuss the issues that should be considered to ensure that individual resident-level form the strong foundations for any data platform for care homes, which must also include, robust infrastructure and clear interoperability, with appropriate governance. It must be co-produced by academics, policy makers and sector representatives, with residents, their families and care staff.
