The development of sustainable policies to manage noise around airports in Vietnam
Authors: Vu Thithanh , Nguyen Thu Lan , Ohya Masaharu , Sakoda Keishi , Yamada Ichiro
Published: February 2023

Before the outbreak of the Corona pandemic, Vietnam was one of the world's fastest-growing aviation markets. With the ambition that more than ninety percent of the population will have access to the airport within 100 km, the Vietnamese government approved developing the airport systems
of 22 existing airports and six new airports. The rapid increase in air traffic in Vietnam has given rise to serious noise problems around airports. Preservation of the living environment for the areas around the airport was an urgent task to the Vietnamese government. Although the situation
has entirely changed by the pandemic, environmental problems will be severe again as the aviation industry recovers. Therefore, a sustainable approach is to create a policy framework to prevent and decrease noise from air traffic parallelly with strengthening the air transport network. However,
although Vietnam issued standards for general environmental noise, there had not been a legal and regulatory system that formed the basis of policies for aircraft noise. In this paper, the authors introduce Vietnam's viewpoints and efforts in developing the framework related to noise management
around airports and discuss future issues and prospects. The authors summarize the activities that the Civil Aviation Authority of Vietnam has been working on with the support of Japanese experts for several years before the outbreak of Corona on noise policy development in Vietnam, including
evaluation methods and monitoring technologies. These efforts have formed the basis for Vietnam's aviation noise policy.
Low-noise friction courses containing treated and un-treated crumb rubber to mitigate tyre/road noise in urban contexts
Authors: Pratico' Filippo G. , Praticò Filippo G.
Published: February 2023

Tyre/road interaction is one of the main causes of traffic noise. This generates health, social, and environmental issues. Low-NMAS mixtures containing crumb rubber (CR) can be used to mitigate the aforementioned issues both in the short and long period. The main objective of the study
presented in this paper is to investigate the variation of volumetric, surface, mechanical, and acoustical properties of friction courses due to the presence of treated and un-treated CR. Low-noise mixtures were designed during the ongoing project "E-VIA" (LIFE18 ENV/IT/000201) and
were used to pave a street in Florence. Several samples were created using the Superpave Gyratory Compactor (AASHTO T-312, UNI EN 12697-31). The first set of specimens, consisting of asphalt concrete, with NMAS=6 mm and bitumen in the range 5-7%, have been used as a reference. Other two sets
of specimens were created adding treated and un-treated CR to the reference mixture and using the dry method. Results show how the different compositions taken into account affect the properties and performance of the mixtures under investigation. Correlations, equations, and main trends were
derived. Future studies will include the comparison between the in-lab produced specimens (herein analysed) and the cores extracted from the aforementioned street.

Authors: Bavaresco Milena , Ferguson Neil , Ibsen Claus Hessler , Bhaskar Atul
Published: February 2023

The separation of closely spaced spectral components is a known problem in signal processing, be it response data either in the spatial or temporal domain. Herein an experimental method based on the maximization of the correlation between measured data and an arbitrary plane wave field
is investigated for its capability in distinguishing closely spaced flexural wavenumbers. Limitations arising from data sampling and windowing are considered. These processes are used along with numerical simulations as a basis to establish the boundaries within which the method successfully
detects the components present. An example from experimental data is also shown, where an alternative method, the empirical mode decomposition, is applied to verify the results and to determine the accuracy of the correlation method in comparison to another existing technique.
Augmented reality for visualization of complex vibroacoustic data sets
Authors: Stewens Thomas , Adams Christian , Pfaff Alexander , Morschel Christopher
Published: February 2023

As technical solutions become more and more complex, analyzing and understanding them must become easier. Especially abstract or perception-biased fields, such as acoustics, can benefit from displaying the behavior of a noise radiating structure in an understandable manner. How can
the acoustic properties of a technical component or a system be displayed in such an understandable way? Due to the current advances in technology regarding the mixed reality spectrum, the HoloLens2 was chosen as the hardware component to run an application and display structural properties
visually. The application is required to display enough data to convey the information without impeding user experience. The application is divided into subprojects. Each subproject is developed and tested in a separate environment. After verification the subprojects were implemented. AR-visualization
reduces the necessary effort to understand the structure's acoustic behavior. Furthermore, explicit knowledge of acoustics is not required to understand the application. In the future, this application can be expanded with additional features such as auralization or a live feed of structures.
Effect of presence of furnishings on designed and measured reverberation time in school spaces
Authors: Prokofieva Elena
Published: February 2023

According to Building Bulletin 93 (BB93), reverberation times for teaching and study spaces are expected to be assessed to comply with the pre-set requirements, when the room is finished and unfurnished. Presence of furniture and people is considered as a changed variable and therefore
not included into assessment. Typically the teaching spaces are modelled by acousticians at the design stage (at RIBA Stage 3 and 4), taking into account only geometry and any surfaces' treatments proposed. During site visits (at RIBA Stage 5), when sample testing is conducted (especially
in large halls or halls of complex geometry to confirm the necessary treatment), the spaces are not furnished. However during the testing, most of teaching spaces are fully furnished, and it seems impractical to test without the furnishings. The ways of taking into account the furniture and
occupancy into reverberation time calculations and measurements, and recommendations on which stage it should be introduced into the design process are discussed in this paper. Examples of compliance on-site tests are provided.

Published: February 2023

Major occupants' complaints received in lightweight wood floors of Impact Insulation Class (IIC) above 55, are low-frequency footstep thumping noise. Lack of understanding of fundamentals and solutions motived this study. A series experiments were conducted to answer the following questions:
1) what are the frequency range of the low-frequency footstep thumping noises heard by the occupants in mass timber slab floor and in light frame wood joisted floor when the floors are impacted by the ISO tapping machine, footsteps of a person walking with shoes, and with bare foot? 2) how
look like the impact sound spectrums below 50 Hz (ISO) or below 100 Hz (ASTM)? 3) Can the tapping machine excite the low-frequency noise down to the range of wood floor natural frequency around 15 Hz? 3) Can the current measurement system measure the sound signals at such low frequency range
reliably? 4) can the measured spectrums of impact sound signals reveal the low-frequency impact noise issues? 5) what are the special construction details of the wood floors contributing to the low-frequency impact noise problem? 6) what are the solutions for the problem? Our experiments answered
the questions. The findings and solutions will be shared in the full-length paper.
Recommendations for the successful design of urban low-noise asphalts - findings from the statistics of over 200 mixtures
Authors: Bühlmann Erik , Schlatter Felix
Published: February 2023

In many countries, low-noise road surfaces have become an established measure to reduce road traffic noise. The focus often is on the high-speed network, where porous asphalts (PA) have been used successfully for decades. For urban areas, however, the design of effective low-noise asphalt
mixtures remains a challenge, as a pore structure is needed that does not clog at lower speeds. Frequently found solutions are fine textured asphalts in the medium void content range with small pores. The challenge in this particular range is to define mixtures that guarantee a certain acoustic
performance. This is exactly where the study comes in: a combined statistical analysis of data from acoustic measurements and laboratory testing of over 200 road surfaces is performed to identify mixtures in the medium void content range (between 8-18% void content) that lead to reliable noise
reduction. Multivariate statistical analysis on over 500 drill core examinations allowed us to identify meaningful subcategories of urban low-noise asphalt mixtures, each of which implying a certain effect mechanism and effectiveness in noise reduction. Based on this data, we give recommendations
for successful grading curve ranges and other mixture design parameters for urban low-noise asphalts grouped into different performance categories.
A basic protocol to characterize classroom acoustics of primary-schools
Authors: Astolfi Arianna , Minelli Greta , Puglisi Giuseppina Emma
Published: February 2023

With the aim to promote a fast and effective characterization of the sound environment in educational facilities and an adequate classroom acoustics design, this work provides a basic measurement protocol which consists of a minimum number of parameters and positions to be considered.
The present study involved 29 primary-school classrooms where background noise level during silent and group activities, reverberation time, speech clarity, useful-to-detrimental ratio and speech levels have been acquired in occupied condition along the main axis and in one or two offset positions.
Two cut-off values of maximum reverberation time to ensure optimal acoustic conditions in the case of moderate and severe requirements, respectively, were assumed equal to 0.8 s and 0.6 s, according to literature and subjective data. For each cut-off value, classrooms were divided in two consistent
groups either if they were compliant or non-compliant with such requirements, respectively. Given the strong correlation among the measured quantities, cut-off values were also identified for the other acoustical parameters. The main result of the work suggests that more convenient parameters,
such as clarity in the central location of the classroom, can be used beyond reverberation time, which implies a more laborious measurement procedure.

Published: February 2023

Airport radars using GPS or radio waves are often used to sense aircraft flight positions. These techniques can be applied for sensing in a wide range of areas, but they tend to be interrupted due to the radar blind spots resulting from the low flight altitude in the vicinity of an
airfield. For managing or investigating aircraft operations, three-dimensional measurement in the local area from the ground is effective. So, we have developed an IoT camera system installed with a fisheye lens and measured the flight path of aircraft passing overhead at multiple points near
the end of the runway. As a result, it was found that our camera system can detect continuous flight paths even if the flight altitude is low.
Classroom acoustics design beyond BB93 - refurbishment of a hearing impaired unit in a mainstream primary school
Authors: Greenland Emma
Published: February 2023

Benchmark acoustic testing was carried out for an existing hearing impairment unit within a mainstream primary school, as part of a feasibility study investigating potential for refurbishment vs. rebuild/relocation. Acoustic measurements comprised reverberation time, internal airborne
sound insulation and indoor ambient noise level. Although the benchmark testing largely demonstrated compliance with the minimum acoustic performance standards outlined in Building Bulletin 93 for refurbishments, it was also important to consider the results in the wider context of individual
school operation and management, and beyond the scope of Building Bulletin 93 performance standards. Interviews with staff and students were carried out to supplement the acoustic measurements and evaluate performance in use. This process revealed additional acoustic problems which were outside
the scope of BB93 but were nonetheless challenging for the children and staff learning in the space. Results will be discussed against the scope of BB93 and findings will be useful to inform future design standards, given the Department for Education's refocus on refurbishment of school buildings
as part of its target to achieve net zero carbon by 2050.
Active Control of an Unbalanced Rotor System using Active Bearings and the Generalized Disturbance Estimation
Authors: Ran Liaoyuan , Halim Dunant , Lin Tingyu , Thein Chung Ket , Galea Michael
Published: February 2023

The work is aimed to develop an active control method for suppressing unbalanced vibration of an elastic rotor system via the utilization of active bearings. The active bearing was implemented by the developed control system to actively control the displacements of the bearing for regulating
the bearing forces. To address the issue of uncertainties associated with the unbalanced forces and internal dynamics of the rotor system, the Extended State Observer (ESO) was utilized to provide an accurate estimation of the generalized disturbance that consisted of the external disturbance
in the form of radial forces caused by the unbalanced rotating mass of the rotor, and the disturbance associated with uncertainties in the internal dynamics of the rotor system. Active Disturbance Rejection Control (ADRC) method was utilized to cancel the effect of the generalized disturbance,
allowing a simpler control input implementation to the active bearing. It was shown in this work that the ESO was able to accurately estimate the disturbances affecting the rotating system in real time. As the result, the active bearing control system could reject the disturbances effectively
to minimize the unbalanced vibration of the rotor system.
Railway Ground Borne Noise (GBN) Reduction by Rail Dampers
Authors: Ho Wilson , Wong Ron
Published: February 2023

Railway GBN impact has raised increasing concerns due to underground transportation expansion. Reducing train speed or replacing standard baseplates with high resilient ones are adopted for GBN control. Both mitigations are not satisfactory considering the installation difficulty and
limited performance, e.g., only ~3dB noise reduction for 30% train speed reduction. On the other hand, FST (Floating Slab Track) are commonly used. In many cases, to accommodate the FST, tunnel diameter is enlarged for the TBM (Tunnel Boring Machine) tunnel section. Also, rail dampers are
used for air-borne noise control, but never used for GBN control due to its relatively small mass. P2 resonance is a main cause of railway GBN. It is a simple harmonic motion of a lump mass (wheel and rail combined) oscillating on top of resilient baseplates. Laboratory test was conducted
with a 6m fastened rail and a ~450kg mass to simulate train wheel and track system. A retrofit rail damper with TMD (Tuned Mass Damping) oscillators was tested. The mass of TMD oscillators along the rail with ~2m effective length of P2 resonance is more than 10% of the wheel. Around 7dB vibration
reduction was recorded at the rail and floor when allowing the TMD oscillation.

Authors: Gümüş Erinç , Bayraktaroğlu Alev Gürol , Kara Kanber , Aksoy Neşe Hayat , Cufadar Yusuf
Published: February 2023

The effect of protected calcium butyrate (PCB) supplemented at different amounts on performance, carcass characteristics, blood biochemical values, jejunum histomorphology, and meat traits in Japanese quails were determined. One‐day‐old unsexed Japanese quails were divided into four groups with seven replicates of seven birds. A conventional corn and soybean meal‐based diet was formulated, and all groups’ diets were supplemented with 0, 0.5, 1.0 and 2.0 g/kg PCB respectively for 42 days. From the results, PCB supplementation significantly improved body weight (BW) on the 21st day, body weight gain (BWG) between 0 to 21 days, hot carcass yield (HCY), and relative weights of the hearth. Similarly, blood urea nitrogen (BUN), total cholesterol (TC), low‐density lipoprotein (LDL) and villus height (VH) levels were lower in PCB‐supplemented groups. Besides, PCB supplementation in Japanese quails decreased the villus‐crypt rate (VCR) except for the control and the group fed with 2.0 g/kg PCB. This study showed that dietary PCB supplementation in Japanese quails’ diet improved growth performance in young chicks and carcass yield, BUN, and lipid profile. On the other hand, the supplementation did not affect the antioxidant status, homocysteine, and folic acid values in blood and meat traits.

Published: February 2023

Drug therapy is among the most widely used methods in disease treatment. However, there remains a trade-off problem between drug dosage and toxicity. Blood purification by adsorption of excessive drugs during clinical treatment could be a solution for enhancing therapeutic efficacy while maintaining normal body function. Here, inspired by the intrinsic action mechanism of chemotherapeutic agents in targeting DNA in the cell nucleus, we present DNA–polyelectrolyte composite responsive microparticles for chemotherapeutics cleaning. The presence of DNA in the microparticles enabled the adsorption of multiple common chemotherapy drugs. Moreover, the microparticles are endowed with a porous structure and a photothermal-responsive ability, both of which contribute to improved adsorption by enhancing the contact of the microparticles with the drug solution. On the basis of that, the microparticles are integrated into a herringbone-structured microfluidic chip. The fluid mixing capacity and the enhanced drug cleaning efficiency of the microfluidic platform are validated on-chip. These results indicate the value of the DNA–polyelectrolyte composite responsive microparticles for drug capture and blood purification. We believe the microparticle-integrated microfluidic platform could provide a solution for settling the dosage–toxicity trade-off problems in chemotherapy.

Diverse defects in copper indium gallium diselenide solar cells cause nonradiative recombination losses and impair device performance. Here, an organic passivation scheme for surface and grain boundary defects is reported, which employs an organic passivation agent to infiltrate the copper indium gallium diselenide thin films. A transparent conductive passivating (TCP) film is then developed by incorporating metal nanowires into the organic polymer and used in solar cells. The TCP films have a transmittance of more than 90% in the visible and nearinfrared spectra and a sheet resistance of ~10.5 Ω/sq. This leads to improvements in the open-circuit voltage and the efficiency of the organic passivated solar cells compared with control cells and paves the way for novel approaches to copper indium gallium diselenide defect passivation and possibly other compound solar cells.

Published: February 2023

El artículo analiza los resultados de una encuesta realizada en la ciudad de Córdoba durante el mes de mayo de 2021, cuando aún estaban vigentes las restricciones sanitarias sobre los espectáculos y actividades culturales con concentración de público. La investigación pone a prueba una serie de hipótesis circulantes que, frente a la limitación y suspensión de la actividad cultural durante la pandemia, suponían: 1) su “traslado” a la virtualidad; 2) la incorporación o el aumento de la frecuencia de consumos culturales tradicionales, como la lectura, en el hogar; 3) la posibilidad de acceder a actividades culturales de lugares distantes disponibles en línea. Los resultados muestran la débil base empírica de las afirmaciones optimistas relativas a la ampliación de las actividades culturales y, en cambio, se evidencia el aumento de prácticas ya instaladas. La encuesta tomó una muestra representativa de la ciudad, utilizando un muestreo de tipo PPS y con un rango de confianza del 95%. Se recogieron en terreno 400 formularios con información referida a los hogares del ejido urbano de la ciudad.
EVALUATION OF ENZYMATIC ALTERNATIVES FOR THE EXTRACTION OF MANGO SEED OIL (Mangifera indica Linnaeus.)
Authors: Torres Elisa Alejandrina Gómez
Published: February 2023

The high production of mango seeds (Mangifera indica linnaeus.) in the Dominican Republic, and especially those from processing companies of this fruit, represents an opportunity to find new possibilities that lead to the use of these wastes in different scenarios. The oils are mainly used for human consumption, animal feed, soaps, cosmetics, biodiesel production and hybrid vehicle motor fuels. In accordance with the above, it is necessary to provide innovative proposals aimed at finding new sources of vegetable oil that allow providing new alternatives in the production of this resource. This new alternative of the use of mango would be an alternative for the use of by-products from the food industry and thus contribute to the reduction of possible environmental impacts. In this investigation it was concluded that the percentage of oil extraction using enzymes was low compared to the extraction by hexane. The mango seed was hydrolyzed using a ternary combination of 65% Alcalase, 25% Viscozyme L and 10% Neutrase. The enzymatic methodology presents an alternative for the extraction of mango seed oil with cosmetic and food applications.
ASSESSMENT OF RAINFALL VARIABILITY AND MAIZE CROP FARMING IN NYANDARUA COUNTY, KENYA
Authors: D.I Muriithi , B.N Wambua , K.J Omoke
Published: February 2023

Crop farming is crucial to the livelihoods of communities living in the rural areas of Kenya. The sector largely depends on climatic variables such as rainfall for optimum crop output. This article presents the analysis, interpretation and discussion of the research findings based on the objective of assessing the climate variability of mean annual rainfall and its impact on crop farming (maize output) in Nyandarua County. To achieve this objective, the researcher sought to analyse rainfall amount and fluctuations in Nyandarua County for 21 years and correlate the variable with crop output (maize) over the same period. The variability of rainfall and maize output was analysed using descriptive statistics of mean, standard deviation and coefficient of variance. Simple line trends and scatter graphs were used to show this variation. The inferential statistics of regression and correlation analysis were used to establish the relationship between the rainfall factor and the selected crop output. The null hypothesis associated to this objective was tested using results of the correlation and regression analysis. Evidence of the study indicated that the annual average rainfall had increased from 1999 to 2006. However, the last fifteen years preceding the study, the mean annual rainfall had significantly fluctuated between the peaks of 117 mm and off peaks of 67 mm. The utmost variation in the rainfall amount was experienced between the years 2013 and 2007. Referring to the 21-year period of annual crop output records, the output of maize greatly fluctuated between 2019 and 1999 with an average tonnes of 29,145.76. Rainfall variability was concluded to have greatly influenced the changes in maize output (r=0.688). The regression line for rainfall variability and maize output produced a slope that was described by the equation y=463x - 11100 + έ. The regression value (R2 = 0.47189 showed that 47.19% of the fluctuation in maize output was as a result of the disparity in rainfall amount and distribution. In conclusion, results of the study implied that rainfall amount and distribution was highly erratic and unpredictable. Therefore this scenario exhibited much uncertainty to the small scale farmers in the region. For better planning of the effect of climate variability, the study recommended that policymakers and other relevant stakeholders should come up with awareness programs through the provision of useful information that assimilate the small holder farmer indigenous knowledge and perception and its effects on their livelihoods with the accurate meteorological scientific data.

The study is carried out to explain the role of entrepreneurial marketing to attain a competitive edge in commercial banks in El Obeid, Sudan 2019. The study problem was represented in the main question ‘what is the impact of entrepreneurial marketing to attain a competitive edge?’ To answer the question, we identified the effect of applying entrepreneurial marketing dimensions to attain a competitive edge in the two main dimensions: cost reduction and aimed quality. For this study, we used the descriptive analytical approach and the case study method. The two main hypotheses of the study were, 1) there is a relationship between entrepreneurial marketing and a competitive edge (cost reduction), and 2) there is a relationship between entrepreneurial marketing and a competitive edge (aimed quality). A questionnaire survey was also carried out with 7 arbitrators. The reliability and validity of the questionnaire were tested with Cronbach's alpha which reached 71%. The study result from the methods and statistical analysis with SPSS shows that there is a relationship between entrepreneurial marketing and a competitive edge (cost reduction) and between entrepreneurial marketing and a competitive edge (aimed quality). Therefore, it is recommended that the bank departments pay more attention and research to address the deficiencies of cost reduction and aimed quality when applying innovative marketing dimensions. The result also supports the continuation of creating the appropriate environment for more practice of creative marketing that reduces the cost of their services.

Agglomeration of aerosol using small equipment with two small aerial ultrasonic sources
Authors: Ono Yuki , Asami Takuya , Miura Hikaru
Published: February 2023

We have developed an ultrasonic agglomeration device that is considerably smaller than previous devices. We used a round-groove small aerial ultrasonic source, which is a compact, intense aerial source of ultrasonic waves. This ultrasonic source generates a large transverse vibration displacement using a circular vibrating plate with a round groove near the tip of the transmission rod, and it produces intense sound waves perpendicular to the vibration plane. In this paper, a compact agglomeration device containing two round-groove small aerial ultrasonic sources was developed, and the agglomeration efficiency was investigated by varying the volume of the device and the input power to the ultrasonic source. The results showed that although this device is small, it has a sufficient agglomeration effect.

Published: February 2023

In this study, stacked graphene diodes were fabricated via direct bonding using single-crystal graphene on a SiC substrate. Switching and S-shaped negative resistance were observed in the junction electrical properties measured via the 4-terminal configuration. The high-resistance state switched to the low-resistance state after applying a maximum junction voltage of ∼10 V. In the high-bias voltage region, the junction voltage decreased from the maximum junction voltage to a few volts, indicating a negative resistance. In the high-resistance state, junction conductance was nearly constant at 0.13 mS. Electrical conductance in the high-bias region was expressed using an exponential function with an exponent of −1.26. Therefore, the fabricated stacked graphene diode with a simple device structure demonstrated strong nonlinear electrical properties with negative differential conductance.

Electric Vehicles (EVs) have become a trending topic in recent years due to the industry’s race for competitive pricing as well as environmental awareness. These concerns have led to increased research into the development of both affordable and environmentally friendly EV technology. This paper aims to review EV-related issues beginning with the component level, through the system level, based on intelligent maintenance aspects. The paper will also clarify the existing gaps in practical applications and highlight the potential opportunities related to the current issues in EVs for the EV industry moving forward. More specifically, we will briefly start with an overview of the fast-growing EV market, showing the urgent demand for Prognostics and Health Management (PHM) applications in the EV industry. At the component level, the issues of the major components such as the motor, battery, and charging system in EVs are elaborated, and the relevant PHM research of these components is surveyed to show the development in the era of EV expansion. Moreover, the impact of an increasing number of EVs at the system level such as power distribution systems and power grid are explored to uncover possible research in the future.
The combination of existing PHM techniques and robust measurement or feature extraction methods can provide better solutions to address the motor, battery, or transformer issues at the component level. A comprehensive optimization and cybersecurity strategy will help to address the issues of the whole network at a system level. Four aspects of vision in the overall charging network – battery innovation, charging optimization, infrastructure evolution, and sustainability – that cover the demands of research in new battery materials, innovative charging techniques, new architectures of the charging network, and reliable waste treatment mechanisms are outlined. A conclusion is reached in this paper by summarizing the opportunities for future EV research and development.

Suicide is the most critical psychiatric emergency that alarms us all yet it is often neglected among healthcare
professionals themselves. While the etiology of suicide is complex bio-psycho-social and occupational factors related, it’s
management is further made difcult due to various barriers to acknowledging the need to seek help and treatment. There is also a lack of a system
for educating about the warning signs, preventive measures and regulatory measures on a larger scale, which is much needed for the
comprehensive management of suicide among healthcare workers in India.

This work aimed to evaluete the acute toxicity and to compare the analgesic and antipyretic effects of a recipe consisting
of a mixture of leaf powders from of S. alata, and J.curcas with these two plants. Acute toxicity was evalueted by oral
administration of a single dose (5000 mg/kg) orally in mice according the OECD, (2001) guideline no. 423. The results obtained show that the
aqueous extracts of the leaves of S. alata, J.curcas and the recipe caused a brief reduction of mobility. However, no mortality and change in
general behavior were observed. Pain was induced by intraperitoneal administration of 0.6% acetic acid in mice and by 2.5% subplantar
formaldehyde in rats. The results obtained show that paracetamol (standard drug, 100 mg/kg), tramadol (standard drug, 10 mg/kg), aqueous
extracts of S. alata (250, 500 and 1000 mg/kg), J. curcas ( 250, 500 and 1000 mg/kg) and the recipe (250, 500 and 1000 mg/kg) signicantly
reduced (P<0.001) the number of abdominal writhing induced by acetic acid as well as the frequency of licking or biting of the paws induced by
formaldehyde during the two phases compared to the control group. These results suggest a peripheral and central analgesic effect of the aqueous
extracts with a potentiation of the effect by the recipe. Fever was induced by subcutaneous administration of a solution of brewer's yeast
(Saccharomyces cerevisiae). The results obtained show that the aqueous extracts of S. alata (250, 500 and 1000 mg/kg), J. curcas (1000 mg/kg)
and the recipe (250, 500 and 1000 mg/kg) signicantly lower (p<0.05) the hyperthermia induced by brewers' yeast with more marked falls
obtained with the receipt between 4 and 5 hours.

Indoxacarb is a non-organophosphorous compound. It is a newer insecticide used rarely compared to the more common
organophosphates by farmers. Hence less information is available on its toxic effects in humans. Timely diagnosis and
management in ER can avoid unnecessary mechanical ventilation and other complications. There are few case reports in the literature about
indoxacarb poisoning, most of them requiring mechanical ventilation. This is a case of indoxacarb poisoning resulting in methemoglobinemia and
seizures timely managed with methylene blue and oxygen support without any need for mechanical ventilatory support.

In ancient times even when medical science was not advanced enough as it is in modern times, ayurvedic physician were
expected to diagnose the diseases as sadhya, krucha sadhya, yapya or asadhya and the treatment was given accordingly.
Even though the stage of disease was considered asadhya & the general rule was not to treat the asadhya. But even acharyas have taken into
consideration the medical duties as a physician and treated the asadhya condition. With the advancement in the medical technology, it has
improved the mortality of medically terminal ill patients but somehow has created problems for the patients who are in suffering and doesn't have
will to live anymore.Demanding for euthanasia by anyone isn't an easy task, creating a lot of chaos before coming to a decision while considering
various factors. Euthanasia literally means mercy killing or putting a person to painless death especially in case of incurable suffering or when life
becomes purposeless as a result of mental or physical handicap still remains an ethical issue. In this paper we are going to explore the current law in
Indian administration in relation to euthanasia. Also, its legalisation in other countries at the present times.
