Published: October 2022

Abstract
This paper represents the numerical methods for the aggregate blending process in the bituminous concrete job mix design. Path variate analysis method and Interval methods were applied to four and five types of aggregate sizes for the blending process. The aspects to be considered in the design job mix design using traditional methods are, that the mix design should be economical, accurate, should consume less time, etc. To achieve these aspects, many numerical methods were developed. It was proven here that the numerical methods specified above are providing a proper proportion of aggregates and the results also seem effective and perfectly within the objective function. The gradation area is computed using the curve fitting approach. Gradation seeks to reduce void space, therefore increasing the mix’s performance. Thus, while comparing the gradation area of mix obtained by two numerical methods such as path variate analysis and interval method for blending process, for five-no. of aggregates 64.163 and 104.169 and for four no. of aggregates 74.687,87.905. This path analysis method blends results have shown less gradation area, hence lesser gradation yields high performance in mix.

Published: October 2022

Abstract
The present study brought out the effort and quantifies the use of geotextile in Low-Volume Roads over the weak subgrade. The Low-Volume Roads (LVRs) play a key role in the economic growth of rural area as well as helps in developing the country. The construction of these LVRs over the weak strength of soil subgrade is a challenging task for civil engineering to provide the safe and smooth flow of traffic, and such soil is revealed that the Black Cotton soil (BC). The weak soil subgrade consists the finer particles like clay and silt showing poor shear strength, bearing capacity, and California bearing ration values. It poses several serious problems to the LVRs. To arrest these problems many of the conventional techniques were adopted in pavement application. But these techniques are nor economical and neither eco-friendly. To reduce this problem, the cost of construction, and to provide a longer duration, geosynthetics are introduced as an alternate material in pavement application in the last few decades. In the umbrella of geosynthetics, the geotextile is gaining attention for its utilization in pavement constructions. The study found the coir composite mats performed better reinforcement and improved the strength of the pavements. This study concluded that the use of coir geotextile mats with appropriate of sub-base soil at the suitable position at H/4 with morrum soil improved the performance of the LVRs with 200mm thickness of mould over the 400 mm thickness of the mould. It is indicate a decrease in construction and maintenance costs of the LVRs.
Decolourization of reactive orange 13 dye using waste agricultural materials as precursors for preparing activated carbon
Authors: Chaudhari D S , Shah K A , Rane D S 
Published: October 2022

Abstract
There are various technologies for treatment of dye wastewater but most efficient, reliable, economic and simple is by adsorption by activated carbon. In this study, an economical activated carbon was prepared from waste materials, sugarcane bagasse and banana peels for the adsorptive removal of reactive orange 13 dye from synthetically prepared wastewater. Physico-chemical characterization of the prepared activated carbons namely, proximate analysis and absorptive capacity indicator numbers were performed. Fourier transform Infrared (FTIR) analysis of the prepared activated carbons was investigated. Batch adsorption experiments were performed by varying parameters like adsorbent dose, dye concentration and pH. The maximum removal efficiency of sugarcane bagasse activated carbon (SB) was 84.82% at starting dye concentration of 100 mg/l, adsorbent dose, 1g adsorbent and pH 3, while the maximum removal efficiency of banana peels activated carbon (BP) was 96.35% at starting dye concentration of 100mg/l, 1g adsorbent and pH 8. The adsorption data fitted the best with Langmuir isotherm for both SB with R2 0.888 and BP with R2 0.988. The result shows that both adsorbents have good potential of colour removal.
Removal of Tannic acid and COD from synthetic Tannery wastewater
Authors: Maisuria K J , Shah K A , Rana J K 
Published: October 2022

Abstract
Tanning industries generate tannery wastewater having high amounts of tannic acid and high COD. Tannery wastewater is difficult to treat as it is having low biodegradability. Tannic acids or tannins are recalcitrant molecules that are toxic to a wide range of microorganisms. In this study, synthetic tannery wastewater treatment was performed by Electrocoagulation (EC) process. To extract the polyphenolic components of tannins, aluminum was employed as an anode electrode and stainless-steel as cathode electrode. Analysis of removal efficiencies was done by determining tannic acid concentration and COD. The effects of functional parameters such as current density, pH, and initial concentration of tannic acid were examined on the efficiency of electrocoagulation. At a current density of 30 A/m2 with an initial concentration of tannic acid of 1,000 mg/L, 94% of tannic acid removal and 94.92% of COD removal were observed. While tannic acid removal was fast, at 60 min, COD removal took a long duration of 120 min. The removal efficiency was observed for three various pH;4.11 (initial pH of the sample), 6, and 8. The maximal COD elimination was found to be accomplished at pH 4.11, which was the sample’s natural pH, whereas tannic acid removal was better at pH 6 and 8. Experiments with a varying initial concentration of tannic acid at 500 mgl−1, 800 mgl−1, and 1000 mgl−1 showed that as concentration was increased, the removal was difficult. The present study found the EC process effective in reducing COD and tannic acid concentration in synthetic tannery wastewater.

Authors: Rane D S , Shah Kosha , Chaudhari D S 
Published: October 2022

Abstract
Landfill leachate contains high concentration of pollutants and treatment of leachate is very challenging as the properties are very fluctuating with quantity and time. Due to presence of non-biodegradable pollutants advanced oxidation processes are found effective to treat landfill leachate. In this study, fresh leachate sample from Jambuva landfill site at Vadodara, Gujarat, India was collected and analysed for the initial characterization. Electro-Fenton process was applied for the treatment of landfill leachate to evaluate the COD removal and colour removal by two methods: i) An external ferrous source is added, and an oxygen-sparging cathode produces hydrogen peroxide., and ii) Using an oxygen-sparging cathode and a sacrificial anode, hydrogen peroxide and ferrous ion are electrogenerated. In the first method, Graphite was used as a cathode and Titanium as anode. In the second method, graphite was used as a cathode and Iron as anode. Continuous electro generation of hydrogen peroxide and Fe ions were measured to assess the efficiency of treatment process. In first method, maximum COD removal (58.22%) was obtained at current density 30 A/m2, FeSO4.7H2O dose of 1 mM and contact time of 150 mins with more than 98% colour removal. Whereas, in the second method, maximum COD removal (46.99%) was obtained at current density 40 A/m2 at contact time of 150 mins with more than 93% colour removal. The electro- Fenton process was found to be efficient for landfill leachate treatment.

Published: October 2022

Abstract
In the recent days usage of nano materials in concrete are responsible in creating ultra-high-performance concrete. Curing is another important strength enhancing parameter in all types of concrete. The nano concrete was achieved by replacing cement in the conventional concrete with Nano silica (NS) in the order of 0.5%, 1%, 1.5%, 2%, 2.5% and 3%. In the present study nano concrete was experimentally explored to mechanical properties like workability, Compressive Strength (CS), Flexural Strength (FS), Bond Strength (BS), Water Absorption (WA), and Thermal Conductivity (TC) test. The mechanical properties were examined at different ages of concrete by subjecting it to four different curing conditions such as water curing, admixture curing, membrane curing and air curing. M30 grade control concrete was compared with the test results. Totally 7 mix proportions by varying nano silica volume were casted. In total 50 cubes (150mm x 150mm x 150mm), 25 prisms (150mm x 150mm x 700mm) were casted to perform the experimental study. Polyethylene glycol 400 (PEG 400) was used an internal curing admixture. Sulpho-naphthalene formaldehyde (SNF) admixture was added by 0.85% weight of cement to enhance the workability of the mix. The results proved the performance of concrete was improved when cement was replaced by 2% of NS and water curing gives the best results in all the mechanical tests performed. Addition of NS beyond 2% weight of cement reduces the fresh and harden properties due to its high Specific Surface Area (SSA). The decrease in porosity was noted with NS addition, hence water curing was best suited curing technique for Nano-concrete.

Abstract
Most of the engineering construction projects of bridges, dams consume huge quantities of concrete and other materials. Economical design can be better achieved by optimising the quantities of materials without affecting functionalities of structures. Minimising the proportions or quantities of materials without affecting its functional characteristics in a concrete mix results in most cost efficient design process. This study presents the technique of optimisation of concrete mix design applying Genetic Algorithms using a developed MATLAB program. Concrete mix design was performed for different grades of concrete and water cement ratio. It is observed that the use of Genetic Algorithms resulted in economical mix by minimizing the cement content keeping the strength of concrete unaffected. The study results indicated that quantities of cement have been reduced by about 25-40 kg per cubic meter through mix design using GA technique. This resulted in about 6-10 percent reduction in quantities of cement for various cases of mix design considered in the study. Mix design performed using optimization techniques like GA proved to be efficient when compared to mix design using manual approach. Further, the models for predicting compressive strength under different proportions of materials can also be analyzed using GA approach presented in this study.
Controlling the photoluminescence of quantum emitters in hexagonal boron nitride by external magnetic fields
Authors: Korkut Hilal , Sarpkaya İbrahim 
Published: October 2022

Abstract
The recent observation of room temperature spin-dependent photoluminescence (PL) emission from hexagonal boron nitride’s (h-BN’s) defect centers motivates for performing a complementary low-temperature photophysical study of quantum emitters under relatively high magnetic fields. Here, we investigate the PL emission dynamics of h-BN’s visible single-photon emitters under an applied out-of-plane magnetic field at cryogenic temperatures. The PL intensity of the emitters in our work strikingly exhibits strong magnetic field dependence and decreases with the increased magnetic field. A substantial decrease in the integrated PL intensity of the emitters by up to one order of magnitude was observed when the applied field is increased from 0 T to 7 T. The observed reversible photodarkening of PL emission due to the applied magnetic field is in very well agreement with the predictions of a recent joint experimental and theoretical study and can happen only if the spin-selective, non-radiative, and asymmetric intersystem crossing transitions proceed from the triplet excited state to the lowest-lying spin-singlet metastable state and from the metastable state to the triplet ground state. Our results not only shed more light on the light emission paths of defect centers in h-BN but also show the use of the magnetic field as an efficient control knob in the development of magneto-optical devices.
Effect of heat treatment on structure and mechanical properties of basalt fibers and its application for fabrication Cu based composite
Authors: Zhu Weiwei , Li Qian , Zou Haohao , Han Ying , Zhao Yu , Ran Xu 
Published: October 2022

Abstract
This paper firstly presents an experimental investigation of the effects of heat treatment temperatures and atmosphere on the tensile strength and structure of basalt fibers. The results show that the basalt fibers after heat treatment in air (200–600 °C) have the characteristics of amorphous state due to the oxidation of Fe2+ into Fe3+. On the contrary, the vacuum heat treatment induces the crystallization of basalt fibers. The reason is that the Fe2+ cations can act as network modifiers and the Fe3+ can participate in and enhance glass network. Furthermore, the single fiber strength of basalt fiber decreases with the increase of heat treatment temperature. However, the single fiber strength of basalt fibers after vacuum heat treatment is about 3 times that of basalt fibers after air heat treatment. On this foundation, basalt fibers were used for fabrication of copper matrix composites by spark plasma sintering (SPS) and hot press sintering (HPS) for the first time. The results exhibit that the strength of basalt fibers reinforced copper matrix composites prepared by SPS is 276 MPa, which are higher than that by HPS (192 MPa) due to fast heating rate and short holding time.

Published: October 2022

Abstract
Discovering the biological basis of aging is one of the greatest remaining challenges for biomedical field. Work on the biology of aging has discovered a range of interventions and pathways that control aging rate. Thus, we developed AgingBank (http://bio-bigdata.hrbmu.edu.cn/AgingBank) which was a manually curated comprehensive database and high-throughput analysis platform that provided experimentally supported multi-omics data relevant to aging in multiple species. AgingBank contained 3771 experimentally verified aging-related multi-omics entries from studies across more than 50 model organisms, including human, mice, worms, flies and yeast. The records included genome (single nucleotide polymorphism, copy number variation and somatic mutation), transcriptome [mRNA, long non-coding RNA (lncRNA), microRNA (miRNA) and circular RNA (circRNA)], epigenome (DNA methylation and histone modification), other modification and regulation elements (transcription factor, enhancer, promoter, gene silence, alternative splicing and RNA editing). In addition, AgingBank was also an online computational analysis platform containing five useful tools (Aging Landscape, Differential Expression Analyzer, Data Heat Mapper, Co-Expression Network and Functional Annotation Analyzer), nearly 112 high-throughput experiments of genes, miRNAs, lncRNAs, circRNAs and methylation sites related with aging. Cancer & Aging module was developed to explore the relationships between aging and cancer. Submit & Analysis module allows users upload and analyze their experiments data. AginBank is a valuable resource for elucidating aging-related biomarkers and relationships with other diseases.
DD-01 THE INVITE STUDY: INCISIONAL HERNIA PREVENTION: RISK-BENEFIT FROM A PATIENT'S PERSPECTIVE
Authors: Smith L , Cornish J , Meggy A , Torkington J 
Published: October 2022

Abstract

Introduction
Incisional Hernia (IH) is a common complication of abdominal surgery. IH is associated with significant morbidity to patients, and costs to the NHS. With no singular intervention demonstrated to bring the rate of IH below 12%, focus is now on pre-operative risk-prediction. High-risk patients may benefit from prophylactic mesh placement during their index operation, however with controversy surrounding the use of mesh, there is no understanding of whether this intervention is acceptable to patients.

Methods
This is a retrospective, single centre mixed-methods cohort study. Patients with and without IH who have undergone colorectal surgery will be approached, along with a smaller cohort of patients about to undergo surgery. Participants will be asked to complete a questionnaire and a sub-set of participants will be invited to semi-structured interviews. The primary objective is to assess the acceptability of prophylactic mesh to patients. Secondary outcomes include understanding patient's views on risk-predictive modelling, and factors that may influence or alter the acceptability of mesh.

Analysis
Questionnaires have been developed using a 5-point Likert scale to allow quantitative analysis. Qualitative analysis of interviews will be conducted using Clarke and Braun's framework of thematic analysis. Data will be presented using the Journal Article Reporting Standards (JARS) for mixed-methods research.

Outcomes
Ethical approval has been granted, and the trial is currently in set-up. Results from this study will be used to inform both in the design and recruitement of patients to future interventional trials using prophylactic mesh in the UK.
DD-05 INCISIONAL HERNIA PREVENTION - INVESTIGATION OF A NOVEL DEVICE FOR STANDARDIZED ABDOMINAL CLOSURE
Authors: Börner G , Montgomery A 
Published: October 2022

Abstract

Aim
Surgeons can reduce incisional hernia formation by adhering to standardized techniques for incisional wound closure. This is often neglected at the end of a long operation which can lead to wound infection, wound rupture and incisional hernia formation. To address this issue, a suturing device was developed for swift and standardized abdominal closure. Preclinical studies have shown an adherence to Suture-Length/Wound-Length ratio ≥4 (SL/WL ratio) of 95% with the device compared to 69% for manual suturing and a &gt;30% reduction in closure time. The aim is to perform a first in man study to verify the device performance and user safety.

Method
The study will be performed in a four month period at a single center. Principal investigator are appointed and research nurse funded. Forty patients undergoing elective open surgery for colorectal disease will be assigned to the study and follow up time will be 45 days. Endpoints will be adherence to SL/WL ratio of 4, abdominal closure time and wound infection. The study will include usability assessment and scoring of surgeon satifaction.

Results
If previous promising results from preclinical studies in animal tissue models and cadavers are verified in patients, this novel suturing device can be an important tool to reduce abdominal wall closure related complications. This will have an impact on patient quality of life, save surgical resources and contribute to a more predictable postoperative pathway.
