Issues and Methods in Meditation Research

Most research has been seen the growing interest in the neurobiological correlates of meditation. They omitted the philosophical aspects of meditation on human being and its wider implications on human. Hence the following issues like definition, study design, and its outcomes need to be study. In meditation research the effects of meditation practice need to examine and also how meditation works is need to study and examine. Some meditation techniques reduce pain, but how meditation affects the brain’s response to pain is not been studied. The brain structural differences between a well-matched sample of long-term meditators and controls using whole-brain cortical thickness also need to analysze. This paper describes the issues related to meditation and their effects on the study of meditation with some explanation of methods in meditation research

Mental State Prediction Using Machine Learning and EEG Signal

One of the most exciting areas of computer science right now is brain-computer interface (BCI) research. A conduit for data flow between both the brain as well as an electronic device is the brain-computer interface (BCI). Researchers in several disciplines have benefited from the advancements made possible by brain-computer interfaces. Primary fields of study include healthcare and neuroergonomics. Brain signals could be used in a variety of ways to improve healthcare at every stage, from diagnosis to rehabilitation to eventual restoration. In this research, we demonstrate how to classify EEG signals of brain waves using machine learning algorithms for predicting mental health states. The XGBoost algorithm's results have an accuracy of 99.62%, which is higher than that of any other study of its kind and the best result to date for diagnosing people's mental states from their EEG signals. This discovery will aid in taking efforts [1] to predict mental state using EEG signals to the next level

Usage Of Gelatin-Virus Balls And Liquid Virus Filled Gelatin Capsules To Control Coral Reef Diseases: Model For Phage Therapy

Coral reefs are very sensitive to environmental pollution. Coral reefs frequently get infected by various bacteria, fungi, marine algae and protozoa. The diseases include Bacterial Infections (BI), Fungal Infections (FI), Black Band Disease (BBD), Black Overgrowing Cyanophyta (BOC), Black Aggressive Band (BAB), Lethal Orange Disease (LOD), Skeleton Eroding Band (SED), PEYssonnelia (PEY), PNEophyllum (PNE) and White Syndromes (WS). Here in we have proposed a proposed model in which cold water soluble gelatin will be used to prepare Gelatin virus balls (GVB) and Liquid virus filled and sealed gelatin capsules (LVFSGC). GVB and LVFSGC will be prepared as per standard protocol in the form of paintballs and capsules. Above mentioned infecting agents of Coral reefs will be used as inoculum for production their production on the pilot scale. These produced infecting agents will be added with specific viruses of infecting agent (host-specific viruses). After the lysis of cell (naturally/artificially), lysate containg host-specific viruses will be used as infecting viruses to the Coral reef infecting agents. This lysate will be used for preparation of GVB and LVFSGC. These paintballs and capsules contain host-specific viruses can be made to release on a surface of sea water and dispersed on affected coral reefs zone naturally by Sea water current/waves. The dispersed viruses from GVB and LVFSGC will attach to their host. Ultimately, the diseasecausing agent may be killed and the coral reef infection will be removed from sea water without any harm to the environment. GVB and LVFSGC will be used for the release of viruses against disease-causing agents. The GVB and LVFSGC will systematically kill and save the coral reefs

Purification, Characterization, and Effect of Thiol Compounds on Activity of the Erwinia carotovora L-Asparaginase

L-asparaginase was extracted from Erwinia carotovora and purified by ammonium sulfate fractionation (60–70%), Sephadex G-100, CM cellulose, and DEAE sephadex chromatography. The apparent Mr of enzyme under nondenaturing and denaturing conditions was 150 kDa and 37 ± 0.5 kDa, respectively. L-asparaginase activity was studied in presence of thiols, namely, L-cystine (Cys), L-methionine (Met), N-acetyl cysteine (NAC), and reduced glutathione (GSH). Kinetic parameters in presence of thiols (10–400 μM) showed an increase in Vmax values (2000, 2223, 2380, 2500, and control 1666.7 μmoles mg−1min−1) and a decrease in Km values (0.086, 0.076, 0.062, 0.055 and control 0.098 mM) indicating nonessential mode of activation. KA values displayed propensity to bind thiols. A decrease in Vmax/Km ratio in concentration plots showed inverse relationship between free thiol groups (NAC and GSH) and bound thiol group (Cys and Met). Enzyme activity was enhanced in presence of thiol protecting reagents like dithiothreitol (DTT), 2-mercaptoethanol (2-ME), and GSH, but inhibited by p-chloromercurybenzoate (PCMB) and iodoacetamide (IA)

Evaluations of Thinning Algorithms for Preprocessing of Handwritten Characters

Thinning algorithms have played an important role in preprocessing phase which decides the success of recognition in the OCR system. This paper report on the performance of 11 thinning algorithms from the perspective of character recognition where different aspects of the performance of each algorithm like computing time, deviation from perfect 8-connectedness, and number of possible noise spurs present in the skeletons are considered

EXPERIMENTAL PERFORMANCE OF DIFFERENT EVAPORATIVE COOLING PAD MATERIAL OF DIRECT EVAPORATIVE COOLER IN HOT AND DRY REGION

An experimental performance of evaporative cooling pads of different materials based on weather data of vidharbha, India has been carried out. Saturation efficiency and cooling capacity of thickness 4 inch cooling pad materials were measured. Effect of air and water flow rate on saturation efficiency and cooling capacity has been investigated for different cooling pad materials like cellulose, khus-grass, and wood-wool material. Saturation efficiency and cooling capacity have been calculated for flow rates of air between 0.25 to 0.45 m3/s and for water flow rate of 60 to 100 cc/hr. Saturation efficiency and cooling capacity variation with water and air flow rate is plotted for different materials of the pads. It has been observed that cellulose material gives highest saturation efficiency of about 92.8% while Khus-Grass material gives lowest saturation efficiency of about 40.13%. The cooling capacity increases with air flow rate and is obtained between 1.1 to 6.72 kW for different materials

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
