Introduction: Awareness with recall (AWR), originally coined as intra-operative awareness, is a recognized risk of general anesthesia (GA). Based on individual factors, patients respond differently to GA. The safety of GA has increased drastically over the past 20 years; however, there is continued opportunity for assessment, evaluation and treatment of AWR. Gibbs, Gibbs and Lennox (1937) first identified AWR in 1937.
Materials and Methods: The Present study was conducted at the Department of Anaesthesiology and Critical Care, Tertiary care center, Guwahati, Assam. Which includes 50 patients who underwent different routine general surgeries and 50 patients from Emergency. Pre-anaesthetic evaluation was done and noted down. In the operating room IV line established, multichannel monitor attached and standard monitoring including baseline pulse, NIBP, SPO2 and ECG connected. Entropy and NM monitoring equipment was attached. The choice of inducing agent, neuromuscular blocker and maintenance for general anaesthesia was based on the patient and nature of surgical procedure.
Results: These 200 patients were interviewed as per the protocol in hospital on the day of surgery. Our study found that among these 200 patients, 2 patients reported remembering something between going to sleep and waking up from anaesthesia, thus 2 cases of awareness were identified. 7 patients reported dreaming and 6 cases of possible awareness were identified.
Conclusion: Awareness occurs despite the usual clinical monitoring of anaesthetic depth like BP, HR and even with the use of entropy. There is currently no evidence that awareness and recall could be prevented by monitoring consciousness with sophisticated methods such as BIS or entropy. If a patient has suffered from awareness and recalls this postoperatively, psychiatric consultation and followup is recommended

The accurate location of epileptic seizures by interpreting an EEG (Electroencephalogram) signal is highly demanding and involves skilled neurologists. In this study, the EEG is analyzed using the Tunable-Q Wavelet Transform (TQWT) method for identifying seizures by splitting an EEG signal into several sub-bands. The entropy computed for each sub-band signifies the nonlinearity in an EEG signal. The other novel parameters viz correntropy, centered correntropy (CCE) and correntropy coefficient assess the nonlinearity of EEG signal and forms the basis for classification. The study has been done on the freely accessible Bonn University EEG database and outperforms in terms of complexity. When contrasted to the existing state-of-the-art methods, 100% accuracy has been achieved in discriminating seizure, seizure-free signals, and non-seizure EEG signals using Random Forest Classifier. Moreover, the computation of the proposed features is fast, and the system is easy to implement.

This paper is devoted to the analysis of advanced scientific research about the role of
superlow intensity EHF effects on biological objects, including people. In this
investigation was utilized Gunn diode with the flow of electromagnetic radiation
superlow intensity of 10 μW and frequency 40-43 GHz. The estimation of the influence
of the millimeter radiation on staphylococcus aureus, E.coli, and the native blood has
been performed. It was shown the death of staphylococcus is associated with the
frequency of modulation signals of the radiation. The EHF irradiation of bacterial
suspension for one minute leads to the short-term disorders of motor function of
E.coli. Exposure by EHF of the super weak intensity causes inhibition of red blood cell
function, which manifests itself in a decrease in their ability to aggregate. Our
experimental data also prove that intake of water activated by means of EHF radiation
modifies the functional status of patients.

Soil samples were taken at the Novaya Panika test site (Frolovsky district, Volgograd region). Dark chestnut soils are represented by varieties of dark loamy and medium loamy on loess-like loams, and light loamy on deluvial loams, represented by sandy deposits. The ratio of the coarse fraction to the fine fraction did not reveal sharp fluctuations in changes in the structure. Differences in indicators occur at such small levels (thousandths and tens of thousandths) that this only indicates an even greater detail of thermodynamic units. The general indicator of a variety of light loamy, medium loamy, heavy loamy dark chestnut soil, destruction associated with erosion, deflation, various types of anthropogenic influences or the synthesis of neoplasms, revealed an entropy indicator (Пs) and energy (ПG) (ПH) equal to 0,5 units. The results of the thermodynamic approach to assessing the intensity of soil formation considered in this work show the broad possibilities of thermodynamic methods. Using the approaches of different scientists in the article on the basis of our data on the granulometric composition and gross chemical composition to the energy of soils, taking into account the entropy and energy components, revealed the importance of the dispersion of matter in their energy intensity. The greatest potential of residual energy is present in the silty fraction of loam varieties of the subtype of dark chestnut soils.

This article highlights the study on the determination of differential heat, isotherm, thermokinetics and entropy of water, carbon dioxide, normal heptane, benzene, methanol, ethanol adsorption on ZSM-5 zeolites, using adsorption-calorimetric method at a temperature of 303 K. The type and number of formed ion-molecular complexes, as well, the mechanism of adsorption of the studied molecules were ascertained. In the zeolite structure, thermokinetics of adsorption and the discovery of the migration laws of exchange cations are considered the adsorption energy of gases and vapors in a flawless zeolite. From the beginning to the saturation, the adsorption isotherm was described by the two- and three-term mathematical equations of STMP.
