Published: January 2023

This research was designed to study the metal stress on plant species, Lantana camara in culture. Plant Tissue Culture techniques are used as a tool, to study the growth of the plants in presence of the heavy metal Lead. Lantana camara is generally known as notorious weed. Indian region have been invaded by several exotic plants of which Lantana camara is of more concern, because of its rapid spread, intensity of infestation, and resistance to cutting and burning. Lantana is a native of tropical America, and was introduced to India as an ornamental to be planted in gardens and hedges. Since then, the species has spread rapidly into both farm and forest lands, and is one of the most widespread, terrestrial invasive species in India today. Despite of this Lantana camara has immense potential of phytoremediation of heavy metals. The industrial area Govindpura, Bhopal contains this plant in majority at heavy metal contaminated area, thus the study has been carried out to evaluate the response of Lantana camara towards lead. The cultures of Lantana camara were firstly established on M S Media supplemented with BAP, NAA and Kinetin and the stable in vitro plantlets then used for further study. The effect of heavy metals on Lantana camara plants under various concentrations of Lead was studied using in vitro culture. The tissue culture experiments were conducted using M S Media.

Authors: Vikash Kumar  , Dr. K. B. Singh  , & Dr. M. N. Haque
Published: January 2023

In this chapter we will discuss the equation of motion of Photogravitational Circular Restricted Three Body Problem (in brief -PCR3BP) in which both the primaries are sources of radiation [1]. The three body problem studies the motion of three masses whose gravitational attraction have an effect on each other. The dynamics of the three-body problem are essentially different from those of two bodies, because in the latter case, an analytical solution may be found that admits orbits in the form of conic sections. This problem has been studied at great length and is the basis of most of today’s orbit planning and trajectory design for satellites.

Utilization of online websites to shop for a range of products has been frequent in our day to day lives. As a result, consumer demand is becoming more diverse, making it difficult for a general store to deliver the proper products based on the tastes of its customers. To deliver a favorable buying experience for the consumer, these E-commerce websites use various recommendation system algorithms. Recommendation systems are a tool for dealing with this problem; they allow you to meet consumer’s demands and expectations while also attracting new ones. A product recommendation system is essentially a filtering system that suggests particular things to customers depending on their interests. Recommendation systems have exploded in popularity in recent years with applications in music, news, movies search queries and others. The bulk of today’s E- commerce sites such as Amazon, Flipkart ,Myntra, make use of their own recommendation algorithms to better offer their customers with products they are likely to like .Recommendation engines are data filtering technologies that use algorithms and data to suggest the most relevant items to the user.

Authors: Dr. Sanampudi Krishna Reddy  , Dr. Alla Mounica  , Dr. Kanna Chandra Varma  , Dr. Rapaka Ashok Reddy
Published: January 2023

Disturbance of the normal anatomic structure and functional integrity of the skin can be described as wound. Chronic or non-healing ulcers are defined as ulcers which are failed to heal in less than 3 weeks of duration .If normal healing process is interrupted ulcer can become chronic in nature due to lack of growth factors and cytokines which is results in delay of wound healing. Conventional treatment for chronic non-healing ulcers includes wound cleansing and necrotic tissue debridement. The use of patient’s own body cells for ulcer treatment relies upon the components present in the blood and platelet concentrate, which contains various cytokines and growth factors. Autologous PRP is a platelet suspension in plasma derived from whole blood that is increasingly being used in clinical practice for the treatment of chronic non healing ulcers.
OBJECTIVE: To assess the efficacy of topical application of autologous platelet rich plasma in wound healings.
METHODOLOGY: The study was conducted in the department of General Surgery, GREAT EASTERN MEDICAL SCIENCES during the period of February 2021 to February 2022 . Ten patients between 18-80 yrs ,of any sex, with chronic non-healing ulcers of different etiologies were treated with topical application of PRP. RESULTS : Ten patients each having ulcer of varying etiology were included .Treated with Topical administration of AUTOLOGOUS PRP solution over the ulcer. Among the included patients 6(60%) were males and 4 (40%) were females with a mean age of 62.5± 13.53 years. Out of 10 patients 4(40%) were in 61-80 years age group,2(20%)were in 41-60 years age group and 4(40%) patients was less than 40 years .The duration of the chronic non healing ulcers presented by the patients range from 9 to 24 weeks with a mean duration of 16weeks.After application of PRP solution ,the mean healing time was found to be almost 8.2 weeks±1.9weeks.After the application of PRP solution small islands of granulating tissue appeared over the wound and a significant reduction in ulcer size was observed as a sign of healing and improvement. CONCLUSION: In our study, the results showed that PRP is a safe and effective treatment modality for chronic non-healing ulcers. Delivering of growth factors to target site enhances the wound healing rates of chronic non healing ulcers.PRP seems to be efficient to treat chronic non healing ulcers which are non responsive to classical conservative treatments. Using PRP to treat chronic wounds/ulcers may not only enhance healing, but also prevent lower extremity amputations caused by nonhealing wounds.There by reducing over all hospital stay, inconvenience of constant medication and morbidity.
Comparative Study of Software Testing Technique using Manually and Automated Way
Authors: Ms. Monika Gupta  , Dr. R. K. Bathla
Published: January 2023

Software could be diagnosed either manually or automatically. The two approaches are complementary: automated testing can perform a huge number of tests in short time or period, whereas manual testing uses the knowledge of the testing engineer to target testing to the parts of the system that are assumed to be more error-prone. Despite this contemporary, tools for manual and automatic testing are usually different, leading to decreased productivity and reliability of the testing process. AutoTest is a testing tool that provides a “best of both worlds” strategy: it integrates developers’ test cases into an automated process of systematic contract-driven testing. This allows it to combine the benefits of both approaches while keeping a simple interface, and to treat the two types of tests in a unified fashion: evaluation of results is the same, coverage measures are added up, and both types of tests can be saved in the same format. The objective of this paper is to discuss the Importance of Automation tool with associate to software testing techniques in software engineering. In this paper we provide introduction of software testing and describe the CASE tools. The solution of this problem leads to the new approach of software development known as software testing in the IT world. Software Test Automation is the process of automating the steps of manual test cases using an automation tool or utility to shorten the testing life cycle with respect to time.
VLSI Implementation of Ternary Operand Binary Addition Using Parallel Prefix Adder for Area Efficiency
Authors: PruthviRaj. Ravi  , Dr. Rajasekhar. Karumuri
Published: January 2023

Cryptographic applications and pseudo random generator perform modular arithmetic three operand is the basic fundamental unit used in all these applications. For performing three operand additions, CSA (carry save adder) is one of the most widely used adders[5]. But in CSA in the final stage, carry is propagated which impacts the delay. Prefix parallel adders are therefore employed to get around this. The parallel prefix adders use more space even though performance in terms of latency is improved. Parallel prefix adders can also be used to build three operand adders. A brand-new, high-speed, and hardware-efficient adder technique is used to boost performance in terms of latency and area. This adder approach uses four stages to achieve three operand addition. Since Han Carlson adder is used in third stage, the suggested adder is not area efficient. To overcome this, in this paper we are replacing the Han Carlson parallel prefix adder with sklansky adder.

Published: January 2023

The imperative need to enforce safety measures to prevent deadly accidents exists in the world of urban traffic environments today. During 2021, two-wheelers have been reckoned for the maximum number of fatal roads accidents accounting for 69,240 fatalities, or 44.5 of total road accidental deaths, followed by cars (23,531 deaths, 15.1) and trucks/lorries (14,622 deaths, 9.4%). Accidents may happen regularly as a result of drivers' carelessness and imperfect indicators of faulty warning signs on the road. Road safety policy's primary focus for several decades included techniques like signs, speed limits, and straightening bends. The system provides the Global Positioning System (GPS), Geographic Information System (GIS), and Global System for Mobile Communications (GSM) to cater to the requirements of some intelligent vehicle monitoring systems. The research presented in this study sheds light on the vehicle's decision-making process by using a novel approach.
Exploring the Relationship Between Contemplative Spaces, Human Experience and Spiritual Architecture
Authors: Raghani Smruti , Brar Tejwant Singh , Kamal Mohammad Arif
Published: January 2023

To lead a fit and peaceful life, it has become very important to dwell in spaces that are contemplative and comforting. Space for contemplation can also lead the architect towards spiritual realms. The current era can be described as tumultuous, changeable, and unsettled. Rapid urbanisation and extreme intensification are being accompanied by technical advancements and a push for sustainability. Traditional architecture was often purpose-built with little care for adapting to new users, various purposes, or changing conditions down the road. Today, however, it is suggested that building flexibility is urgently required due to climate change, changing demographics, resource depletion, and affordability issues. It is believed that architecture in the twenty-first century must approach similar levels of flexibility and adaptability for a variety of reasons, one of which being the mental health and spiritual connection of the user. Rather than deconstructing structures to fill landfills, our architecture should be designed to be disassembled, reassembled, and reused in order to generate spaces of contemplation. There can be various ways in which architecture can bring out such spaces. It can be a garden oasis in urban land crowded with buildings, a small skylight in a dark space, framing a window to form a vista. Which language of architecture has to be used to create contemplative space depends upon for whom the space is being designed. The current study is the result of extensive literature reviews in the fields of contemplative architecture and spirituality. The focus of this paper is to study the impact of physical surroundings and architectural structures on leading a healthy lifestyle. Different spaces can be designed which connect the user to themselves in a deeper way by proposing a space where they have freedom to think or meditate and feel the present moment. People suffering from depression or stress can benefit from such contemplative spaces.
Wastewater Treatment and Recycling of Western Sydney Airport
Authors: Jiang Xialiang
Published: January 2023

The topic of this thesis is wastewater treatment and recycling of Western Sydney Airport. Due to the airports’ increasing demand for water and the limitation of total water resources, it is necessary to design a wastewater treatment and recycling system for Western Sydney Airport. There are two primary types of wastewater generated by an airport: wastewater generated by passengers and wastewater generated by the operation and maintenance of the airport. The treatment of these two types of wastewater should be designed separately since these two types of wastewater have different pollutants. The primary pollutants of wastewater generated by passengers are similar to domestic wastewater, which contains organic pollutants, the primary pollutants of wastewater generated by the operation and maintenance of the airport are nitrogen and carbon compounds. By designing a wastewater treatment and recycling system, the water consumption of the airport can be reduced significantly.

Authors: Liu Weiguo , Wang Xuyin
Published: January 2023

Aiming at the uncertainty of the intelligent manufacturing system, this paper reveals the evolution mechanism of the manufacturing system and its internal and external environment from a data-driven perspective. And it proposes an adaptive dynamic scheduling method based on scenario deduction, which provides the basis for the intelligent manufacturing support in an uncertain environment. Firstly, the paper uses the ontology to describe the scenario status, production activities, market environment and production subject of manufacturing system. And then builds the scenario deduction model based on the dynamic fuzzy cognitive map, establishing the data-driven manufacturing scenario network structure. Through the dynamic fuzzy cognitive map, it presents the market and production scenario evolution and accordingly guides the adaptive choice of dynamic scheduling strategy in uncertain production environment. The results show that the scenario deduction model is basically consistent with the manufacturing system evolution process in terms of time inference and demand prediction, and it verifies the adaptability and effectiveness of the proposed dynamic dispatching method through examples.

Preparing Students for the Internationalized World — Is Hong Kong Secondary English Curriculum Ready?
Authors: Liu Feifei
Published: January 2023

To educate students for an internalized world and knowledge-based economy, education in Hong Kong needs to keep up with internalization of education. English's status as a global language is crucial to achieving the objective. Based on Rizvi's (2007) critique of curriculum internationalization, this paper examines the secondary English curriculum of Hong Kong as a case study and assesses the curriculum's readiness for internationalization at the policy, school, and classroom levels. The results of this study demonstrate that curriculum internationalization has had a subtle impact on secondary English curriculum decision-making, particularly at the office and school policy levels. However, because to Hong Kong's strongly engrained exam-oriented setting, internationalization adoption at the classroom level continues to be a difficult and convoluted process.

Authors: Wang Guangsheng
Published: January 2023

The fast rise of China's real estate business has efficiently propelled the country's economy, and it is also profoundly entwined with the daily lives of the Chinese populace. There are more investment risks associated with real estate projects due to the size of the investment funds, the length of time required to accomplish the task, the effect of regulatory changes, the market climate, and other variables. If these risks are not appropriately managed, they will lower the investment's return. Real estate project investments should be more cautious and scientific, fully assess investment risks, and target the appropriate control measures to reduce the impact of risk factors and ensure the smooth implementation of investment activities. This is particularly crucial in light of the new normal, which involves increased uncertainty.

Why Can the Frail Status Quo in the Taiwan Strait be Preserved? Analyzing the Econ-political Synergy among China, Taiwan, and United States
Authors: Shen Chenxi
Published: January 2023

This paper uses analytic eclecticism to answer why the fragile status quo in the Taiwan Strait remains resilient. After pragmatically framing the research question, this research chooses three symbolic scenes in the Taiwan Strait: (1) Beijing’s economic statecraft towards Taiwan; (2) Taiwan’s soft power in finding the leeway out of its international dilemma; (3) The Sino-America competition over the narration in the cross-Strait relations. As a practice of eclecticism where the analytical framework is constructed based on each major school of international relations theories, this paper combines cases and theoretical tools to draw the whole picture of Taiwan issues. Ultimately, this research reached empirical and theoretical conclusions, calling for an innovative international relations theory that observes political phenomena conceptually and practically.

Posthumanism Invited to Dinner: Exploring the Potential of a More-Than-Human Perspective in Food Studies
Authors: Elton Sarah
Published: January 2023

[from para.1]: "A PLATE OF FOOD AWAITS. A chicken thigh seasoned with the lemony accents of sumac. On the side, rice cooked with small brown lentils topped with onions, fried until brown and crispy. Leafy greens, steamed, salted, dressed with olive oil. What is happening here? Well, dinner awaits the diner, a hungry human wishing to nourish the body and satisfy the taste buds. Food will be tasted, digested, and transformed by bodily functions into nutrients and waste. Or maybe not. What happens at the dinner table if we take a posthumanist perspective and consider the agency of the nonhuman? Posthumanism is the term I use to group the theories and approaches that seek to remove humans from a self-appointed role as supreme actor on planet earth and recognize meaning and agency in other life forms—and even phenomena and matter. Posthumanism levels the playing field—flattens the ontology—and provides a framework for a radically different world of networks, assemblages, companionship, relating and interrelating."
Toronto municipal staff and policy-makers’ views on urban agriculture and health: A qualitative study
Authors: Mulligan Kate , Archbold Josephine A. , Baker Lauren E. , Elton Sarah , C. Cole Donald
Published: January 2023

Municipal governments across the Global North are increasingly becoming key actors in shaping urban food and agriculture policy. In the City of Toronto, recent aspirational policies, such as the provincial Local Food Act and the municipal Toronto Agricultural Program, created new opportunities to shape a healthier food system. We sought municipal perspectives on the question of “How might urban agriculture policy and programs be better supported to promote equity and health?” Analysis of findings from semistructured key informant interviews with municipal staff and policy-makers (n=18) illustrated broad support for generating better quantifiable evidence of the impacts of urban agriculture on economic development and employment, health and health equity, land use and production, and partnerships and policies. Place-specific economic and equity data emerged as particularly pressing priorities. At the same time, they sought better approaches to the potential risks involved in urban agriculture. Key informants also shared their views on the use of health impact assessment research to make a case for urban agriculture to a range of stakeholders; to manage real and perceived risks; and to move beyond enabling policies to empower new investments and procedural changes that would facilitate urban agriculture expansion in the city. The results informed the evolving praxis agenda for urban agriculture at the intersections of population health, environmental sustainability, and urban governance
Growing Methods Developing a Methodology for Identifying Plant Agency and Vegetal Politics in the City
Authors: Elton Sarah
Published: January 2023

A methodology for plant qualitative research is at an early stage of development. While conducting a multispecies ethnography of gardeners and the plants they grow for food in a neighborhood in transition from social housing to a mixed-income community in Toronto, the author wondered, How to account for plants and their agency? What is evidence of vegetal politics? What is a multispecies ethnographer doing when decentering the human in relation to garden plants, beyond what isun-done ontologically? This article situates itself in the plant turn and proposes a methodology to account for plant agency in gardens and to identify vegetal politics. The author builds on the methodological work of other scholars of human-plant relations and posthumanist notions of relational agency to develop a three-step method: (1) recognize plant time, (2) participate with plants, and (3) scale up. Central to the methodology—and a key contribution the author puts forward—is a shift away from the researcher considering plants as individuals and instead understanding plant communities as the unit of analysis. This shift in scale, while recognizing plant time and the relational agency of plants, permits the identiﬁcation of vegetal politics and has allowed the author to theorize plants as political actors in cities that support health.
Is the ‘obesity crisis’ really the health crisis of the food system?: The ecological determinants of health for food system change
Authors: Elton Sarah
Published: January 2023

Multilateral organizations and research institutions are increasingly calling for transformation of the industrial food system due to its negative health impacts, its contribution to climate change and the fact that the system fails to provide adequate food to more than 800 million people. A common rationale given for food system change is the so-called obesity crisis. This commentary draws from critical weight studies and ecological public health discourses to argue that it is unnecessary to connect the crises of the food system with a rise in overweight and obesity. This approach contributes to fat stigma and further marginalizes a group of people who already suffer from stigmatization. A more inclusive rationale for food system change can be found in a concept articulated by the Canadian Public Health Association termed the ‘ecological determinants of health.’ These are features of the biosphere such as water, air, food and soil systems that support life on earth and human health. The current industrial food system threatens the ecological determinants of health by contributing substantially to climate change and environmental degradation. A shift in discourse in food policy and practice to focus on the ecological health impacts of the food system is more inclusive and promotes the well-being of all.

Traumatic brain injury due to primary blast exposure is a major cause of ongoing neurological and psychological impairment in soldiers and civilians. Animal and human evidence suggests that low-level blast exposure is capable of inducing white matter injury and behavioural deficits. There are currently no effective therapies to treat the underlying suspected pathophysiology of low-level primary blast or concussion. Remote ischemic conditioning (RIC) has been shown to have cardiac, renal and neuro-protective effects in response to brief cycles of ischemia. Here we examined the effects of RIC in two models of blast injury. We used a model of low-level primary blast in rats to evaluate the effects of RIC neurofilament expression. We subsequently used a model of traumatic brain injury in adult zebrafish using pulsed high intensity focused ultrasound (pHIFU) to evaluate the effects of RIC on behavioural outcome and apoptosis in a post-traumatic setting. In blast exposed rats, RIC pretreatment modulated NF200 expression suggesting an innate biological buffering effect. In zebrafish, behavioural deficits and apoptosis due to pHIFU-induced brain injury were reduced following administration of serum derived from RIC rats. The results in the zebrafish model demonstrate the humoral effects of RIC independent of anesthetic effects that were observed in the rat model of injury. Our results indicate that RIC is effective in improving outcome following modeled brain trauma in pre- and post-injury paradigms. The results suggest a potential role for innate biological systems in the protection against pathophysiological processes associated with impairment following shockwave induced trauma.

Skull bone represents a highly acoustical impedance mismatch and a dispersive barrier for the propagation of acoustic waves. Skull distorts the amplitude and phase information of the received waves at different frequencies in a transcranial brain imaging. We study a novel algorithm based on vector space similarity model for the compensation of the skull-induced distortions in transcranial photoacoustic microscopy. The results of the algorithm tested on a simplified numerical skull phantom, demonstrate a fully recovered vasculature with the recovery rate of 91.9%.
Image-Guided High Intensity Focused Ultrasound System for Large Animal Nerve Ablation Studies

Published: January 2023

High intensity focused ultrasound (HIFU) is a form of thermal ablation technique, which can treat a variety of medical afflictions. One promising therapeutic use is the permanent destruction of nerves non-invasively in patients with severe spasticity or certain types of pain (e.g., phantom limb pain). To this end, HIFU requires ultrasound guidance, which allows the non-invasive, target-specific deposition of thermal energy to the targeted nerve, thereby blocking axonal conduction. In this paper, a composite system comprising both ultrasound-imaging and HIFU therapy was developed and used to induce localized non-invasive nerve blockage in an in vivo large animal study. Five pigs were used with the femoral nerve as the target. Calibrated needle thermocouples inserted at the target site were employed to monitor the target tissue temperature. The degree of nerve blockage was assessed by measuring compound action potential (CAP) signal with a clinical nerve electrophysiology system before and after HIFU exposures. An average CAP signal amplitude reduction of 49% of baseline with a standard deviation of 9% was observed after 20-30 min post exposure. These results demonstrate the feasibility of the proposed ultrasound-guided HIFU modality as a potential non-invasive nerve ablation method.
Skull’s Photoacoustic Attenuation and Dispersion Modeling with Deterministic Ray-Tracing: Towards Real-Time Aberration Correction

Published: January 2023

Although transcranial photoacoustic imaging has been previously investigated by several groups, there are many unknowns about the distorting effects of the skull due to the impedance mismatch between the skull and underlying layers. The current computational methods based on ﬁnite-element modeling are slow, especially in the cases where ﬁne grids are deﬁned for a large 3-D volume. We develop a very fast modeling/simulation framework based on deterministic ray-tracing. The framework considers a multilayer model of the medium, taking into account the frequency-dependent attenuation and dispersion effects that occur in wave reﬂection, refraction, and modeconversionattheskullsurface. Thespeedoftheproposedframeworkisevaluated. Wevalidate the accuracy of the framework using numerical phantoms and compare its results to k-Wave simulation results. Analytical validation is also performed based on the longitudinal and shear wave transmission coefﬁcients. We then simulated, using our method, the major skull-distorting effects including amplitude attenuation, time-domain signal broadening, and time shift, and conﬁrmed the ﬁndings by comparing them to several ex vivo experimental results. It is expected that the proposed method speeds up modeling and quantiﬁcation of skull tissue and allows the development of transcranial photoacoustic brain imaging.
Ultrasound shear wave simulation based on nonlinear wave propagation and Wigner-Ville Distribution analysis

Published: January 2023

This paper presents a method for modeling and simulation of shear wave generation from a nonlinear Acoustic Radiation Force Impulse (ARFI) that is considered as a distributed force applied at the focal region of a HIFU transducer radiating in nonlinear regime. The shear wave propagation is simulated by solving the Navier’s equation from the distributed nonlinear ARFI as the source of the shear wave. Then, the Wigner-Ville Distribution (WVD) as a time-frequency analysis method is used to detect the shear wave at different local points in the region of interest. The WVD results in an estimation of the shear wave time of arrival, its mean frequency and local attenuation which can be utilized to estimate medium’s shear modulus and shear viscosity using the Voigt model.

Published: January 2023

Background: The main goal of ultrasound therapy is to have clinical effects in the tissue without damage to the intervening and surrounding tissues. Treatments have been developed for both in vitro and in clinical applications. HIFU therapy is one of these. Non-invasive surgeries, such as HIFU, have been developed to treat tumors or to stop bleeding. In this approach, an adequate imaging method for monitoring and controlling the treatment is required. Methods: In this paper, an adaptive compressive sensing representation of ultrasound RF echo signals is presented based on empirical mode decomposition (EMD). According to the different numbers of intrinsic mode functions (IMFs) produced by the EMD, the ultrasound signals is adaptively compressive sampled in the source and then adaptively reconstructed in the receiver domains. In this paper, a new application of compressive sensing based on EMD (CS-EMD) in the monitoring of high-intensity focused ultrasound (HIFU) treatment is presented. Non-invasive surgeries such as HIFU have been developed for various therapeutic applications. In this technique, a suitable imaging method is necessary for monitoring of the treatment to achieve adequate treatment safety and efficacy. So far, several methods have been proposed, such as ultrasound radiofrequency (RF) signal processing techniques, and imaging methods such as X-ray, MRI, and ultrasound to monitor HIFU lesions. Results:In this paper, a CS-EMD method is used to detect the HIFU thermal lesion dimensions using different types of wavelet transform. The results of the processing on the real data demonstrate the potential for this technique in image-guided HIFU therapy. Conclusions: In this study, a new application of compressive sensing in the field of monitoring of the HIFU treatment is presented. To the best of our knowledge, so far no studies on compressive sensing have been carried out in the monitoring of the HIFU. Based on the results obtained, it was showed that the number of measurements and Intrinsic Mode Functions have the function of noise reduction. In addition, results were shown that the successful reconstruction of the compressive sensing signals can be gained using a threshold based algorithm. To this end, in this paper it was shown that by selecting an suitable number of measurements, the sparse transform, and a thresholding algorithm, we can achieve a more accurate detection of the HIFU thermal lesion size.
