The growth in the number of people affects the production of waste that is not processed properly. Indiscriminate disposal of waste results in environmental pollution which will have an impact on other lives. In addition, the low level of public awareness in sorting waste according to its type contributes to environmental pollution. The existence of these problems certainly requires an innovation that can support and increase public awareness, especially from an early age, in waste management. This Stimulus Community Partnership Program (PKMS) activity is one of the strategies to provide literacy assistance in waste management to the younger siblings of the Putri Aisyiyah Jember Orphanage. Understanding regarding the importance of protecting the environment, the dangers of waste if it is not managed properly, needs to be given early, from an early age. The waste management literacy assistance consists of several activities, including: socialization of the dangers of waste, its types, material value for waste (4R) reduce, reuse, recycle and replace, then ends with activities of sorting garbage around the orphanage and grouping according to type . This PKMS activity has been completed, so that it reaches the evaluation stage of the entire process of community service activities. The results of the evaluation of the younger siblings: they were greatly helped by the existence of these activities as for increasing literacy in keeping the environment clean and not disposing of waste in an inappropriate place. Appreciation was also given by the managers of the girls' orphanage who were grateful for helping people care about their own environment. It is hoped that the community will begin to be aware of the effectiveness of waste management in the future.

Published: August 2023

Zinc oxide nanoparticles (ZnO-NPs) have a significant feature due to their uses in various fields including medicine, biosensors, food additives, and electronic materials. This study aimed to the green synthesis of ZnO-NPs using aqueous extract of Ziziphus-spina christi leaves (Sider) and evaluates its protective roles against liver disorders after adenine-exposed male rats. Thirty-six male rats (3 months in age and weighing 200 ± 5 g) were randomly divided into 6 equal groups as following: Control adenine, Ziziphus-spina christi, ZnO-NPs, adenine + Ziziphus-spina christi and adenine + ZnO-NPs for 30 days. At the end of 30 days, the activity of (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), superoxide dismutase (SOD) and concentrations of reduced glutathione (GSH) and nitric oxide (NO) were determined, as well as the liver histopathological alterations were investigated. Moreover, the body weight of all rats was measured over a week. The synthesized ZnO-NPs was characterized using several techniques. UV-Visible analysis showed a specific absorption peak at 362 nm. In Fourier Transform Infrared spectroscopy (FT-IR) absorption bands of Zn-O stretching bonding showed between 400 and 500 cm−1. Their crystallinity, hexagonal shape, size, and the specific surface area for the dry ZnO-NPs were also determined using the techniques of X-ray diffraction (XRD) and scanning electron microscopy (SEM) respectively. Results showed significant decreases in ALT, AST and ALP in both groups adenine + Ziziphus-spina christi leaves extract and adenine + ZnO-NPs in comparison to the adenine group (p < 0.05), as well as significant increases in body weight. Significant decrease was also demonstrated in NO level associated with an increase in SOD, and GSH. Based on these results, it can be said that ZnO-NPs and Ziziphus-spina christi leaves effectively protect against adenine-induced liver disorders, these were confirmed by improvements marked in histological changes of liver tissue of rats.
GRAPHICAL ABSTRACT
The Impact of Road Side Friction on the Traffic Flow of Arterial Roads in Varanasi
Authors: Srivastava Kartik , Kumar Ajay
Published: August 2023

Varanasi's prominence as a cultural and historical center means it receives visitors from all over the world. The city's tourism industry is a boon to the local economy. Better transportation infrastructure is crucial to attracting more tourists and increasing revenue. Varanasi is currently experiencing terrible difficulties due to various roadside frictional activities. Vehicle ownership grows in tandem with population growth. The increase in the number of vehicles on the road significantly impacts the reliability of the transportation network since land availability is fixed. The various roadside frictional activities usually found in the streets of Varanasi are on-street parking, pedestrian crossing, and Non-Motorized Vehicles (NMVs). There are not enough legal on-street parking and segregated lanes for NMVs/slow-moving vehicles or demarcation for pedestrian movements in the old city of Varanasi. Vehicles in Varanasi are traditionally parked on the street due to the narrow carriageways. Slow-moving vehicles are forced to move with fast-moving vehicles, and pedestrian crossings affect traffic flow. Integrated movement of slow-moving vehicles and rapid-moving vehicles affects traffic speed, pedestrian crossings impact the Level of Service (LOS), and on-street parking results in the reduction of the effective carriageway width and, hence, road capacity. This paper aims to identify the impact of pedestrian crossings, NMVs, and on-street parking on the traffic flow, speed, capacity, and LOS of urban arterial roads in Varanasi. To achieve this objective, two case studies were considered: the base section (with minimum side friction) and the friction section (with maximum side friction). The videography method was used for data collection. Nine hours of data were collected from 9:30 am to 6:30 pm. The video was played on the screen for data extraction. The speed model was developed by using fundamental diagram methods. Speed-density curve was drawn using Greenshield’s model. The speed-flow curve was derived from the speed-density curve to estimate the capacity at the base and friction sections. Reduction in capacity was determined by comparing friction section capacity with base section capacity. V/C ratio of a particular road compared with the V/C value provided by IRC 106 to predict LOS. A correlation model was developed between the percentage reduction in capacity and road width. Increase in parking, the proportion of NMVs, and pedestrian crossing frequency reduce the traffic flow. It was observed that a 6.42% capacity loss occurs at a 7.00% reduction in effective width, and a 35.09% loss occurs at a 36.02% reduction in effective width. Roads with frictional activities found their LOS class affected up to LOS-E (for the Bhelupur section).
A Technological Nanofluid for Washing Off Oil Deposits and Increasing Oil Recovery
Authors: Mamulaishvili Nora , Partskhaladze Gaioz , Chavleshvili Gocha , Khitarishvili Tea , Salimova Nigar
Published: August 2023

The productivity of wells in the late stage of oil production is directly related to oil deposits, which gradually form blockages, fill the pipeline, and interfere with the free movement of the flow of produced oil. Based on chemical composition, oil deposits are difficult to remove and require the selection of process fluids. An extractive method is proposed for the removal of oil deposits with the participation of process fluids, including nanofluids. The proposed nanofluid was prepared on the basis of low-viscosity petroleum oil with the addition of an organic solvent, a mixture of various classes of surface-active substances (surfactants), and alkali metal salts. The nanofluid contains a nanosolution based on alkali metal salts, with concentrations of Na3PO4=13700ppm, KCl=950ppm, and CaCl2=241ppm, which were determined by the readings of an ICPE-9820 spectrometer. It was found that the tested process fluid reduces the viscosity of deposits and interfacial tension and leads to an increase in fluid movement in the pipeline. The experiments were carried out in the direction of reducing the interfacial tension at the interface with the solvent. It was shown that the process of sediment reduction depends on the composition of the ARPD, the surfactant, the composition of the solvent, and the salinity of the nanosolution. It is advisable to flush oil deposits from the surface of the tubing using the process fluid when creating a circular circulation in a closed annular space - tubing – annulus circuit.
An Improved Recursive Least Square Algorithm For Adapting Fuzzy Channel Equalizer
Authors: Zerdoumi Zohra , Abdou Latifa , Bdirina Elkhanssa
Published: August 2023

Adaptive filters have been thoroughly investigated in digital communication. They are especially exploited as equalizers, to compensate for channel distortions, although equalizers based on linear filters perform poorly in nonlinear distortion. In this paper, a nonlinear equalizer based on a fuzzy filter is proposed and a new algorithm for the adaptation parameters is presented. The followed approach is based on a regularization of the Recursive Least Square (RLS) algorithm and an incorporation of fuzzy rules in the adaptation process. The proposed approach, named Improved Fuzzy Recursive Least Square (IFRLS), enhances significantly the fuzzy equalizer performance through the acquisition of more convergence properties and lower steady-state Mean Square Error (MSE). The efficiency of the IFRLS algorithm is confirmed through extensive simulations in a nonlinear environment, besides the conventional RLS, in terms of convergence abilities, through MSE, and the equalized signal behavior. The IFRLS algorithm recovers the transmitted signal efficiently and leads to lower steady-state MSE. An improvement in convergence abilities is noticed, besides the RLS.

Authors: Nanavati Manan M. , Shah Mehul
Published: August 2023

Image fusion is a method of combining the necessary and relevant information from the set of source images into a single (fused) image which can be deemed to be more informative than the source. This paper discusses the implementation of various pyramid-based image fusion algorithms, such as the Laplacian pyramid, the ratio of the low-pass pyramid, the contrast pyramid, and the filter subtract decimate pyramid on multimodal CT and MR images of the lumbar spine. The fused images were evaluated using various objective evaluation quality metrics. The experimental results demonstrated that the ratio of the low pass pyramid achieved better performance compared to the other pyramids implemented, indicating that the fused image can also be used for further image fusion application or analysis purposes.
Fatigue Performance of Rib-to-Deck Double-Sided Weld Joint of Orthotropic Steel Deck on Plate Girder Railway Bridges
Authors: Amritraj Radha Krishna , Mishra Shambhu Sharan
Published: August 2023

This research work presents the stress behavior of rib-deck weld joints in Orthotropic Steel Deck (OSD) railway bridges. It is essential to determine the most vulnerable load mode of the wheels for fatigue failure of OSD bridges and to improve the fatigue resistance of the welded rib-deck connection. Fatigue performance largely depends on the weld stress. Double-sided welds for rib-deck welds improve fatigue performance. The fatigue behavior of the rib-deck double-sided weld joint has been compared with the single-sided one. This study used Abaqus software to create the global shell model and the solid submodel of the OSD. The results of the structural stress-based finite element analysis indicated that when the center line of the front axle pair of a locomotive coincides with the center line of the midspan of the bridge, the most severe loading condition occurs. The rib near the main girder experiences the maximum structural stress in the weld toe of the rib-deck joint. Moreover, the rib-deck double-sided weld joints have 43.7% less structural stress compared to single-sided weld joints at the root of the weld, and this improves the performance during fatigue of OSDs.
Emotion Recognition From Speech and Text using Long Short-Term Memory

Published: August 2023

Everyday interactions depend on more than just rational discourse; they also depend on emotional reactions. Having this information is crucial to making any kind of practical or even rational decision, as it can help to better understand one another by sharing our responses and providing recommendations on how they may feel. Several studies have recently begun to focus on emotion detection and labeling, proposing different methods for organizing feelings and detecting emotions in speech. Determining how emotions are conveyed through speech has been given major emphasis in social interactions during the last decade. However, the real efficiency of identification needs to be improved because of the severe lack of data on the primary temporal link of the speech waveform. Currently, a new approach to speech recognition is recommended, which couples structured audio information with long-term neural networks to fully take advantage of the shift in emotional content across phases. In addition to time series characteristics, structural speech features taken from the waveforms are now in charge of maintaining the underlying connection between layers of the actual speech. There are several Long-Short-Term Memory (LSTM) based algorithms for identifying emotional focus over numerous blocks. The proposed method (i) reduced overhead by optimizing the standard forgetting gate, reducing the amount of required processing time, (ii) applied an attention mechanism to both the time and feature dimension in the LSTM's final output to get task-related information, rather than using the output from the prior iteration of the standard technique, and (iii) employed a powerful strategy to locate the spatial characteristics in the final output of the LSTM to gain information, as opposed to using the findings from the prior phase of the regular method. The proposed method achieved an overall classification accuracy of 96.81%.
The Mineralogical and Chemical Composition of the Strongly Magnetic Egyptian Black Sand Altered Ilmenite
Authors: Moustafa Mohamed Ismail
Published: August 2023

The Egyptian black sand contains several types of altered ilmenite grains which have various magnetic susceptibility values, ranging from the strongly paramagnetic, such as ilmenite, to the non-magnetic, such as rutile grains. The altered ilmenite grains of relatively higher mass magnetic susceptibility, separated at 0.1, 0.2, 0.25, and 0.35 A using the Frantz isodynamic magnetic separator, were investigated. Both brown and black altered grains were investigated using the binocular microscope and the Cameca SX-100 microprobe. Most analyzed spots of grains are composed mainly of pseudorutile (psr) and leached pseudorutile (lpsr), with the contents of TiO2 and Fe2O3 ranging between 56.76 and 78.09% and 37.98 and 12.16%, respectively. The Ti/(Ti+Fe) ratio ranges between 0.59 and 0.85. The chemical formula range of the investigated psr-lpsr is Fe2.07-0.54Ti3O9-4.68(OH)0-4.32. The lowest cationic iron content of the lpsr phase is 0.5 with a corresponding molecular formula of Fe0.5Ti3O4.5(OH)4.5. In the detected leached ilmenite spots, the cationic Fe2+ ranges between 0 and 2.46, while the cationic Fe3+ ranges between 0.17 and 1.94. The Ti/(Ti+Fe) ratio ranges between 0.51 and 0.6, and the Fe/Ti ratio ranges between 0.91 and 0.67. Considering the chemical formula of ilmenite is Fe3Ti3O9, the leached ilmenite formulas have the composition Fe2.72-2.02Ti3O9 with the minimum value of total iron being equal to 2.02. Some of the contained inclusions may be responsible for the acquired magnetic characteristics of some of the detected altered grains. The powdered X-ray diffraction patterns of the investigated different magnetic grains were detected before and after heating at 1100 oC for one hour. The hexagonal psr/lpsr structure is more unstable at 1100 oC than the tetragonal rutile structure. According to the calculations of the molecular formulas for the detected alteration phases, the lowest iron content of the altered lpsr is much lower than that previously reported. Also, during the alteration process, the alteration mechanism is changed in the region of 68-70 wt % of contained TiO2. Then, in the late alteration stages, the lpsr structure does not suddenly collapse but gradually produces other associated mineral phases.

In this paper, the use of radial screens in an Electrical Capacitance Tomography (ECT) sensor is investigated with the aim of resulting in higher-resolution images. The effect of the screens on the quality of the reconstructed images was simulated. 12-electrode ECT sensors with and without screens were designed and tested. The capacitance between different electrode pairs was measured for two permittivity distributions. The obtained capacitance data were used to reconstruct images using the Projected Landweber Iteration algorithm based on linear and semi-linear ECT models. The sensitivity of the measurements and the accuracy of the obtained images for the ECT sensors with and without screens were analyzed. The main conclusion is that a little improvement in the quality of images can be achieved with the use of 12-Electrode ECT sensors with radial screen.
Bending Analysis of Steel-Concrete Composite Beams with Porosity
Authors: Kumar Prashant , Kumar Ajay
Published: August 2023

This study investigated the bending behavior of a simply supported pervious composite beam using the finite element method based on cubic order beam theory. The cubic order axial displacement was assumed and solved using shear stress-free conditions on the extreme surfaces of the composite beam. For simplicity, this study considered one-dimensional axial displacement. Three nodded finite elements were assumed, and each node had eight unknowns. Shear locking was eliminated in the present model by numerical integration of the stiffness matrix. A uniform porosity distribution was implemented in the upper layer of the composite beam. The damping ratio was also considered for the bending analysis. The accuracy of the present model makes it robust for the analysis of composite beams.

Three different PCAs, in the frequency range of 0.1 to 2 THz, conventional and after the addition of cylindrical, triangular, square, and hexagonal geometric gold nanoparticles to the antenna gap region between the electrodes, were built and simulated. The antenna directivity increased from 4.71 dBi to 4.92 dBi when square nanoparticles were added to the bowtie PCA, from 4.33 dBi to 4.45 dBi when triangular nanoparticles were added to the dipole PCA, and from 7.18 dBi to 7.52 dBi when square nanoparticles were added to the Vivaldi PCA.

The Adiabatic Flame Temperature (AFT) in combustion represents the maximum attainable temperature at which the chemical energy in the reactant fuel is converted into sensible heat in combustion products without heat loss. AFT depends on the fuel, oxidizer, and chemical composition of the products. Computing AFT requires solving either a nonlinear equation or a larger minimization problem. This study obtained the AFTs for oxy-methane (methane and oxygen), oxy-hydrogen (hydrogen and oxygen), air-methane (methane and air), and air-hydrogen (hydrogen and air) for stoichiometric conditions. The reactant temperature was 298.15 K (25°C), and the pressure was kept constant at 1 atm. Two reaction mechanisms were attempted: a global single-step irreversible reaction for complete combustion and the GRI-Mech 3.0 elementary mechanism (53 species, 325 steps) for chemical equilibrium with its associated thermodynamic data. NASA CEARUN was the main modeling tool used. Two other tools were used for benchmarking: an Excel and a Cantera-Python implementation of GRI-Mech 3.0. The results showed that the AFTs for oxy-methane were 5,166.47 K (complete combustion) and 3,050.12 K (chemical equilibrium), and dropped to 2,326.35 K and 2,224.25 K for air-methane, respectively. The AFTs for oxy-hydrogen were 4,930.56 K (complete combustion) and 3,074.51 K (chemical equilibrium), and dropped to 2,520.33 K and 2,378.62 K for air-hydrogen, respectively. For eight combustion modeling cases, the relative deviation between the AFTs predicted by CEARUN and GRI-Mech 3.0 ranged from 0.064% to 3.503%.

Poultry retail meat shops are endpoints in the meat chain and can have a determinant role in cross-contamination control. Considering this, a total of 160 retail poultry meat shops in and around Nagpur city of Maharashtra state were assessed for hygienic status and meat handling practices. Meat handlers from poultry meat shops were interviewed through a structural questionnaire. It was found that 83.7% of meat shops had no provision of separate docks for edible and inedible products. In terms of design and facilities, only 27.5% of shops had the facility of flyproof windows. 80.6% of meat shop workers lack training in handling meat and equipment. It was observed that about 83.1% of meat shop workers do not wash their hands properly before entering and leaving the meat shop. About 25% of meat shops do not have any arrangement for the disposal of waste material. Considering the findings to improve the hygienic status and reduce transmission of diseases due to consuming contaminated meat, regular surveillance of poultry shops and formal training of butchers are necessary.

There is great demand for native chicken meat due to its unique strong flavour, firm and hard texture and lower fat content and fetches almost thrice the price of broiler meat. During the last few years, improved native chicken varieties are being introduced to meet the demand and the market share is steadily increasing. The present study was conducted to compare the carcass characteristics and meat quality attributes of improved native chicken varieties viz., Vanaraja (dual purpose chicken) and Indbro (slow growing coloured broiler) with Commercial broilers. In this study, total of 30 birds, comprising 10 birds each from Vanaraja (56 days old), Indbro (49 days old), and Commercial broilers (38 days old) at their respective marketable age were selected for evaluation. Analysis of carcass traits revealed significantly (P<0.05) higher live wt, dressed carcass wt, and breast yield (% of live wt) for Commercial broilers compared to Indbro and Vanaraja birds, whereas the yield of legs, wings, and neck (% of live wt) were higher for Vanaraja birds compared to other groups of birds. The results of meat quality parameters like proximate composition revealed significantly (P<0.05) higher % of moisture, protein, and ash for meat of Vanaraja birds compared to other groups, whereas fat % was significantly (P<0.05) higher in Commercial broilers. Significantly (P<0.05) higher redness (a*) values, lower lightness (L*) values, higher muscle fibre diameter and hydroxyproline content was noticed in Vanaraja birds compared to other groups. Commercial broiler chicken meat showed significantly (P<0.05) higher pH, TBARS and water holding capacity (%) values compared to other groups. Sensory evaluation scores for cooked breast meat samples revealed comparatively higher appearance, flavour, juiciness, texture, and overall acceptability scores for Vanaraja and Indbro birds than Commercial broilers. Shear force values were significantly (P<0.05) higher for Vanaraja followed by Indbro and then Commercial broilers. Microbial analysis indicated lower total plate count (TPC), yeast and mould and psychrotrophic counts for Commercial broilers. The results of study indicated that though the Commercial broilers have better carcass traits compared to Vanaraja and Indbro birds, these improved native chicken varieties have better meat quality attributes and have potential to form a significant source of chicken with better sensory attributes.

Purpose

Simple MRI features are mandatory to facilitate the diagnostics of synovial sarcomas, especially for radiologists outside multidisciplinary sarcoma centres. In this case-series and review, we investigate the main appearance of synovial sarcoma on MRI.

Material and methods

Fifteen histologically proven primary synovial sarcomas who underwent MRI at 2 different sarcoma centres were included in this case series. Patients and their primary synovial sarcomas were examined for age, localization, mean tumour size (in mm), histological grade (G – according to the Fédération Nationale des Centres de Lutte Contre Le Cancer [FNCLCC]), configuration, T2 signal intensity, presence/absence of “triple sign”, heterogeneity/homogeneity, borders (well-defined or infiltrative), and intensity of contrast enhancement on MRI. Additionally, a comprehensive literature review to identify observational studies, reviews, and case-reports assessing MRI features of primary synovial sarcoma was performed.

Results

The mean age of the patients was 47.6 years (SD: 17.2). The mean size of primary synovial sarcoma was 59.3 mm (SD: 42). Primary synovial sarcomas were significantly most often multilobulated (n = 12, p < 0.01), heterogeneous (n = 10), and infiltrative (n = 9). Additionally, 3 other primary synovial sarcomas showed the following configurations: ovoid/nodular (n = 2) and fascicular (n = 1). Ovoid/nodular synovial sarcomas were solely depicted as homogeneous with well-defined borders. All tumours showed T2 hyperintense signal and presented with marked contrast enhancement.

Conclusions

Primary synovial sarcomas are mainly multilobulated, heterogeneous, and infiltrative tumours. In minor cases, ovoid/nodular or fascicular configurations occur. Knowing the main appearance of synovial sarcoma can help facilitate the diagnostics of primary synovial sarcomas.
