INTRODUCTION: Infantile hemangioma is the most common benign tumor in infancy. Currently, oral propranolol is the treatment of choice for infantile hemangioma, but there is no consensus when it comes to its recommended dosage for this condition. Hence this study was conducted this study to find out the appropriate dosage of oral propranolol for treatment of infantile hemangioma. METHODS: A prospective study was conducted on 25 patients with infantile hemangioma, who were treated with gradually increasing dose of propranolol starting from a lower dose of 1mg/kg/day. RESULTS: 17/22(76%) patients showed regression of the tumor at the dose of 1-1.5 mg/kg/d. 5/22(24%) patients were unresponsive on lower dose and they did not respond even with the gradually escalated dose of 3-4 mg/kg/day. CONCLUSION: Propranolol in a lower dose of 1-1.5 mg/kg/day is safe and efficacious in the treatment of infantile hemangioma and the lesions which do not show initial response to the lower dose are unlikely to respond to the higher dose of 3-4 mg/kg/day.

National audience; Climate change is predicted to cause severe loss in agricultural production by increasing disease epidemics and intensifying abiotic stresses. Therefore, there is a need for sustainable methods to alleviate plant stress, such as non-thermal plasma. Here we review the role of non-thermal plasma for plant treatment, with focus on the control of viruses, bacteria, fungi and other diseases. We present factors influencing the microbicidal activity of non-thermal plasma. Application of non-thermal plasma for combating abiotic stresses such as drought, metal toxicity, nanoparticles and salinity are discussed. Plasma-generated reactive species trigger the activity of stress-responsive genes in plants. The hypothetical mechanisms involved in triggering the activity of different stress-responsive genes controlling diseases as well as abiotic stresses, are also presented and discussed. The mechanism of plant-plasma interaction is similar to priming, hormesis or adaptive response, and resembles vaccination in animals and humans.

Introduction: The Sexually transmitted diseases (STDs) are a global health problem of great magnitude. The pattern of STDs differs from country to country and from region to region. The increased risk of the transmission of HIV is known to be associated with the presence of sexually transmitted diseases (STDs) and despite the presence of the National STD Control Program in India the number of people with STDs remains high. Aim: The aim of our study was to study the profile of patients in a STD clinic in North India and to study various sexually transmitted infections in both male and female patients. Material and Methods: A prospective study of the patients attending STD clinic in a district hospital in North India from December 2009 to December 2012 was done. A total of 2700 patients attending the STDclinic in three years from December 2009 to December 2012 were taken up for the study. Results: The commonest sexually transmitted infection in males was herpes genitalis (30%) followed by 20% cases of genital warts. 10% patients had gonorrhoea, genital molluscum contagiosum, syphilis and genital scabies each and 5% patients had nongonococcal urethritis. Only 5% of the total patients had chancroid, donovanosis and LGV. The commonest sexually transmitted infection in females was vaginal discharge seen in 40% patients, lower abdominal pain in 20% patients, herpes genitalis in 15% patients followed by 20% cases of genital warts and syphilis each. Genital molluscum contagiosum was seen in 5% patients only. Conclusions: The treatment of STD’s is important as both non-ulcerative and ulcerative STDs increase the susceptibility to or transmissibility of HIV infection and as such, an increase in STD prevalence as revealed by clinic attendance in this study was bound to facilitate the spread of HIV/AIDS. Perhaps it is high time health planners adopted a more aggressive and result oriented HIV/AIDS/STD awareness campaign strategy.

Sundararajan and Chakraborty (2007) introduced a new sorting algorithm by modifying the fast and popular Quick sort and removing the interchanges. In a subsequent empirical study, Sourabh, Sundararajan and Chakraborty (2007) demonstrated that this algorithm sorts inputs from certain probability distributions faster than others and the authors made a list of some standard probability distributions in decreasing order of speed, namely, Continuous uniform < Discrete uniform < Binomial < Negative Binomial < Poisson < Geometric < Exponential < Standard Normal. It is clear from this interesting second study that the algorithm is sensitive to input probability distribution. Based on these previous findings, in the present paper we are motivated to do some further study on this sorting algorithm through simulation and determine the appropriate empirical model which explains its average sorting time with special emphasis on parametrized complexity.

The present pandemic situation has increased the demand for plant-based functional foods that enhancing the immunity of all aged groups against COVID-19. This factor has led to innovation in confectionery market because healthy and good quality confectionery products are lacking. In this study, an attempt has been made to develop functional candy from various combinations of banana, ginger, skim milk powder, and honey at 2-10% and evaluated its sensory, nutraceutical, functional properties and microbial stability for 60 days. Among various combinations of banana and ginger pulp, candy prepared from 96:6 w/w (banana: ginger) ratio was found better than other combinations in respect to organoleptic and nutritional quality. Ginger and skim milk powder addition increased the contents of protein (4.54%), ash (2.82%), phenolic (8.59 mgGAE/g), flavonoid (2.43 mQ/g), and antioxidant activity (36.15% DPPH activity) of functional candy. Microbial studies of functional candy revealed that it could be stored up to 60 days without microbial contamination and acceptable by the consumer. The cost of functional candy was Rs.1.53 per candy, which was less than market candy. This study showed that candy manufactured from banana, ginger, skim milk powder, and honey was nutritionally and economical improved with acceptable sensory properties. Developed functional candy increases the market's revenue and enables confectionary market to develop a new candy type. [ABSTRACT FROM AUTHOR]

Developing countries need infrastructure for development thereby increasing the demand for concrete. The production of raw materials, manufacturing of concrete, and transportation process emit a large amount of greenhouse gases and particulate matters in the atmosphere which has increased energy consumption as well as global warming potential (GWP), acidification potential (AP), and eutrophication potential (EP) impact. In the present study, a comparative Life Cycle Assessment (LCA) is performed on five types of concrete mix and two fuels like coal and agricultural waste. The controlled mixed concrete CM-O was prepared by 100% OPC and the other four types of agricultural waste concrete were prepared by partial replacement of cement with agricultural waste ash in one cubic meter concrete. Optimum replacement level of cement was obtained based on 28 days compressive strength of concrete. LCA was evaluated by using CML methodologies on Microsoft excel for Cradle - to - gate boundary system. Similarly, environmental load due to the burning of coal and agricultural waste was evaluated. The results indicated that agricultural waste concrete has the potential to decrease the environmental load of the manufacturing of concrete. The environmental load is 1701.985 kwh, 501.051kg, 4.327kg and 466.091g for energy consumption, GWP, AP, and EP respectively for one cubic meter of controlled mix concrete. The results indicated that Rice husk ash at a replacement level of 12.5% of cement has 4.3%, 10%, 7.1%, and 3.7% lesser environmental impact for energy, GWP, AP, and EP respectively when compared with controlled mixed concrete. Further, the use of agricultural waste as fuel emits very less amounts of greenhouse gases mainly CO2, SO2, and NOx, and has an overall less impact on environmental compared to coal. This study would encourage the industrialists to make decisions about the use of agricultural waste as supplementary cementitious materials (SCMs) and fuel.

A lot of studies have shown that the synchronous switch energy producer solutions increase the rate of energy production from vibration (i.e.) piezoelectric ones which comes with capacitive output impedance. These ones use inductive branch to compensate capacitive source. Some studies have done the reciprocal (i.e.) to compensate inductive source they use capacitive branch. In these, the controllers are very bulky which is not a desired ones for making sustainable energy for the IOT devices. This synchronous switch method will work with two rounds of ON/OFF actions in each vibration cycle. By this method we can improve the power factor, thus the energy production is increased. This method uses very less amount of switching actions than other methods we use just like pulse width modulation ac-dc rectifier designs. The detailed working is given in this article. It also shows the result proving that this synchronous switch method outperforms the diode- bridge rectifier energy converting methods by 62.1%-96.4%.

To incorporate leadership in the governance of the Employees, one must have a thorough awareness of the various advantages of EI in HEI. Following the development of artificial intelligence came the emergence of emotional artificial intelligence, being aware that increasing the presence of emotions in AI would raise the likelihood of parallels between humans and machines. It will also be able to comprehend humans and be more likely to identify the root cause and consequences of an issue. Many of the gadgets in our bedrooms and kitchens are artificially intelligent to assist us with everyday activities, but they lack the emotional intelligence to adjust to our needs. An artificial intelligence that satisfies a person's needs needs to be capable of adjusting to their mental state. At the MIT laboratory, several technologies are being created. A total of 309 publications on the relevance of emotional intelligence in leadership were found in the scientific databases Scopus and Emotional Intelligence Important in Leadership, out of which 105 were chosen for further study. The Bibliometric tool was used to process the data; it included details on yearly production, journal analysis, author analysis, document analysis, keyword analysis, etc. Managers and policymakers in organizations in general and Higher Educational Institutions in specific can get some valuable inputs from the study's findings that will help promote artificial intelligence with emotional intelligence in their respective organizations that will ensure their growth, stability, and prosperity.

Power quality is one of the prime views of modern energy schemes. Renewable-energy-based microgrids offer an attractive solution for improving the power quality of remote or isolated areas while diminishing greenhouse gas discharges. However, incorporating renewable energy origins into the grid can introduce significant challenges, mainly power fluctuations, voltage instability, harmonics, and frequency deviation. Here, a literature-based study has been done on the power quality improvement in microgrid. This review paper analyses 30 literature review papers published between 2018 to 2022, focusing on power quality improvement in recoverable -energy-based Microgrids. It also analyses the different techniques, simulation environments, and controllers used in each research work. Moreover, the advantages and research gaps in the collected research articles are also analyzed. Ultimately, the research gaps identified are also mentioned to assist future researchers in developing a novel and efficient approach for power quality improvement in microgrid-based systems.

Agriculture plays a key role in deciding the economy of the country and agricultural marketing has become the potential driver of the agricultural sector. Green revolution and succeeding technologies made our farmers to succeed in the production front, but lagging appreciably in terms of price realization owing to their inability to stop post-harvest losses and inaccessibility to efficient and scientific marketing system. Post-harvest management includes storage, packaging, coating, disease management, extended shelf life, maintaining food quality. Foods and other products can be preserved by storage at low temperature, which retards the activities of microorganisms and preserve perishable foods in their natural state. Preservation depends on the storage time required whether short or long-term short and the type of product. A cold storage unit works on two principles: Vapour absorption system (VAS), and Vapour compression system (VCS). Although VAS is a bit costlier, but economical in operation. Food irradiation is another recent food preservation technology to address some of post-harvest losses. Food is exposed to ionizing radiation (i.e. radiowaves, microwaves, UV rays, X-rays, gamma rays etc.). Food irradiation can be applied to specific purposes as quarantine treatment of fruits and vegetables and as a method to ensure hygienic quality of foods. Food processing techniques like grading, sorting and packaging, etc add value and enhances shelf life of food. Agricultural productivity augmentation needs a concurrent development of post-harvest support mechanism and efficient and organized marketing system, which would ensure maximum price rrealization to the farmers.

Grapes (Vitis vinífera L) is extensively cultivated and widely consumed fruit world wide But it is also very highly susceptible to fungal infections such as B cinérea which increases post-harvest losses, quality deterioration, and making it unsuitable for human consumption. This results in significant economic loss of grapes and impacts grape farmers’ profits. Therefore, there is an urgent need to identify potential methods and approaches to decrease post-harvest losses of grapes caused by B. cinérea. Currently, synthetic fungicides are used to control grape infections which has harmful impact on the environment and human health. Therefore, essential oil from plants sources could be a potential alternative to synthetic fungicides. In this study, antifungal activity of three essential oils was evaluated against B. cinérea using fumigation method. In an in vitro study, the essential oils extracted from Zingiber officinale and Saturaga montana, each at a concentration of 4mg/mL, exhibited complete inhibition (100%) of fungal growth. The physiological study of fruit in term of TSS, pH and weight loss showed that there is slow deterioration of fruit during storage. In-vivo results showed that essential oil from natural source can be potential alternative for synthetic fungicides which is ecofriendly and effective to control diseases and post-harvest losses in grapes.

Cherry Tomato (Solanum lycopersicum L. var. cerasiforme) believed to be the progenitor of modern cultivated tomatoes, is one of the world’s most cultivated and widely consumed vegetables. However, it is very susceptible to fungal (Botrytis cinerea) infection, which decreases shelf life, and increases post-harvest loss. Postharvest loss and lower quality of fruit decrease the economic value of the crop or may make it unsuitable for human consumption and affect farmer profit. Therefore, an effective method is needed to reduce tomato’s post-harvest loss. This study aims to assess the efficacy of Zingiber officinale oil and Piper nigrum oil in controlling fungal disease in tomato fruit. The antifungal activity of essential oil was evaluated using the essential oil fumigation method. The result showed that essential oil significantly inhibits Botrytis cinerea growth as compared to the control. Therefore, essential oil can effectively control the fungal diseases of cherry tomatoes against Botrytis cinerea fruit rot and reduce the post-harvest loss of tomatoes.

Chilli (Capsicum annuum L.) holds a prominent position as a key spice crop, being widely utilized globally. Despite its agricultural significance, chilli is characterized by high moisture content (60–85%) at harvest, necessitating reduction to 8-12% for prolonged storage in a dehydrated form. However, it remains highly perishable, with a short shelf life and susceptibility to postharvest challenges such as fungal diseases, quality degradation, chilling injury, and rapid weight loss. Edible coatings have emerged as a solution to extend the postharvest shelf life of fruits and vegetables, enhancing mechanical handling properties and acting as a barrier to respiratory gases and water vapor. The possibility of hydrocolloid gums, such as gum arabic, as edible coatings has drawn interest. The purpose of this study is to determine whether an edible coating based on gum arabic (GA) can effectively preserve the quality of chiles when stored at room temperature. The goal of the research is to extend the storage life of chiles while improving their physiological and microbiological quality. A composite chitosan – gelatin (CH–GL) edible covering will be used to accomplish this. The effects of pure chitosan, cassava starch, gum arabica, and gelatin coatings on chillies will also be investigated in this study. In order to improve the marketability and resilience of chilli and possibly other horticultural commodities, the research aims to offer insights into the development of efficient and sustainable postharvest strategies by methodically evaluating the effects of these coatings on weight loss, firmness, colour retention, and nutritional content.

The study aimed to compare ARIMA and Holt's models for predicting coconut metrics in Kerala. The coconut data series was collected from the period 1957 to 2019. Of this, 80% of the data (from 1957 to 2007) is treated as training data, and the rest (20% from 2008 to 2019) is treated as testing data. Ideal models were selected based on lower AIC and BIC values. Their accuracy was evaluated through error estimation on testing data, revealing Holt's exponential, linear, and ARIMA (0,1,0) models as the bestfit choices for predicting coconut area, production, and productivity respectively. After using the testing data, we tried for the forecasting for 2020-2024 using these models, and the DM test confirmed their significant forecasting accuracy. This comprehensive analysis provides valuable insights into effective prediction models for coconut-related metrics, offering a foundation for informed decision-making and future projections.

Nanoparticles have emerged as a promising platform for the delivery of vaccines due to their unique properties, such as their small size, high surface area, and tunable surface properties. Coating these nanoparticles with antigens and adjuvants enhances their stability, immunogenicity, and targeting ability, thereby leading to improved vaccine efficacy. Vaccines have revolutionized the field of immunization, providing effective protection against numerous bacterial infections. This review paper expl ores the diverse strategies employed by vaccines to stimulate a robust immune response and confer immunity. Various vaccine types, including inactivated toxins (toxoids), live bacterial vaccines, live attenuated vaccines, and virus -like particles (VLPs), are investigated in terms of their mechanisms and suitability for different populations. While live bacterial vaccines and live attenuated vaccines have demonstrated efficacy, caution must be exercised when administering them to individuals with compromised immune systems. As an alternative, VLPs have emerged as a promising non-infectious option that closely resembles viral structures. VLPs offer advantages in terms of safety, cost-effectiveness, and their ability to elicit targeted immune responses, this could lead to significant breakthroughs in vaccine development. Ongoing research is dedicated to the development of vaccines targeting specific pathogens and combating antimicrobial resistance (AMR). Innovative approaches include mRNA-based vaccines, vaccines designed to target surface polysaccharides, vaccines that induce helper T cell responses, and vaccines against specific virulence factors. By understanding the mechanisms and potential applications of different vaccine types, researchers and healthcare professionals can contribute to the continued progress in immunization and protect individuals and communities from the burden of infectious diseases.

The Indian Government is providing grains to those in need at affordable prices through a process known as the Public Distribution System. However, the current distribution methods employed in the public distribution system rely on manual processes, which may lead to errors, be time-consuming, and foster corruption. To address these issues, the proposed work employs Advanced Interdisciplinary Techniques such as RFID cards and readers to authenticate ration cardholders and ensure precise ration dispensing, significantly reducing inaccuracies and fraudulent activities. Furthermore, it incorporates a GSM-based mechanism with OTP authentication, adding an extra layer of security and efficiency. The GSM module sends a one-time password (OTP) to the user’s registered mobile number before dispensing rations, ensuring that only authorized individuals receive their entitled goods. Customers can select the goods they need from the allocation provided by the Government, and the amount will be automatically deducted from their RFID card based on the goods selected. A microcontroller manages the motor and relay to dispense items, while an alarm system alerts in cases of incorrect OTP entries, effectively deterring unauthorized access to rations. This system promises to make the ration distribution process more efficient, transparent, and accountable.
