This paper presents an analysis of current foreign trends in neurocognitive rehabilitation of cognitive disorders in Alzheimer's dementia (AD) and neuropsychological rehabilitation of the most common form of vascular cognitive disorders (VCD) - aphasia. Two approaches to the restoration of higher mental functions (HMF), based on a different understanding of the neuroplasticity mechanisms, are described. The description presents non-invasive and functional methods of direct stimulation of HMF. Various methods of transcranial brain stimulation and Intensive Language-Action Therapy (ILAT) are reviewed and analyzed. The data of experimental studies present the application of these methods to the restoration of Broca's aphasia. The paper also considers an approach to neurorehabilitation based on the methodology of "workaround" recovery of HMF using sensory-enriched environment. The article describes and analyzes the theoretical foundations of Music Intonation Therapy (MIT), Thérapie mélodique est rythmée) (TMR), palliative MIT, Music Therapy (MT). The paper carries out an analytical review of the implementation of abovementioned methods in aphasics. Also, programs and neurocognitive correction methods in mild cognitive impairment (MCI) are considered. The paper describes the possibilities of using active and passive MT, STAM-DEM Therapy, and Multimodal Cognitive Enhancement Therapy (MCET) in AD. The study presents the data of systematic and meta-analytical reviews on their use in MCI. The paper describes the methodology of "musical" neuropsychological diagnostics in dementia.

Abstract Predicting thermal response in orthopedic surgery or dental implantation remains a significant challenge. This study aims to find an effective approach for measuring temperature elevation during a bone drilling experiment by analyzing the existing methods. Traditionally thermocouple has frequently been used to predict the bone temperature in the drilling process. However, several experimental studies demonstrate that the invasive method using thermocouple is impractical in medical conditions and preferred the thermal infrared (IR) camera as a non-invasive method. This work proposes a simplified experimental model that uses the thermocouple to determine temperature rise coupled with the thermal image source approach. Furthermore, our new method provides a significant opportunity to calibrate the thermal IR camera by finding out the undetected heat elevation in a workpiece depth.

Analytical Review

Over the past 20 years, a large number of studies have been published on reducing storm runoff by various types of green roofs. This article analyzes the results of experimental studies presented in 39 publications on green roof runoff reduction in a climate similar to the climate of Russia: in Canada, the USA, Finland, Norway, France. An analytical review found that the ability of green roofs to retain rainfall varies from 20 to 99.5% depending on climatic conditions (duration and intensity of rains, duration of dry periods, solar radiation, temperature and humidity, wind conditions), the properties of green roof layers (moisture capacity of the substrate and a drainage layer, the substrate thickness), the type of vegetation, the geometry of a green roof (slope and orientation). Green roofs can be a useful tool for reducing urban storm water runoff. However, in order to ensure high efficiency, it is necessary to use green roof technology with other measures to reduce runoff.

This paper presents a new approach for bearing defect diagnosis in induction motor by taking advantage of three-phase stator current analysis based on Concordia transform. The current signature caused by bearing defect is firstly analyzed using an analytic model. Concordia transform is performed to extract the instantaneous frequency based on phase demodulation. The bearing defect feature is then identified via spectrum analysis of the variation of current instantaneous frequency. Both simulation and experimental studies are performed to demonstrate the effectiveness of proposed method in identifying bearing defects. The method is inherently low cost, non-invasive, and computational efficient, making it a good candidate for various applications.

Reciprocating-piston compressors and expanders are promising solutions to achieve higher overall efficiencies in various energy storage solutions. This article presents an experimental study of the exergetic losses in a gas spring. Considering a valveless piston-cylinder system allows us to focus on the thermodynamic losses due to thermal-energy exchange processes in reciprocating components. To differentiate this latter loss mechanism from mass leakages or frictional dissipation, three bulk parameters are measured. Pressure and volume are respectively measured with a pressure transducer and a rotary sensor. The gas temperature is estimated by measuring the Time-Of-Flight (TOF) of an ultrasonic pulse signal across the gas chamber. This technique has the advantage of being fast and non-invasive. The measurement of three bulk parameters allows us to calculate the work as well as the heat losses throughout a cycle. The thermodynamic loss is also measured for different rotational speeds. The results are in good agreement with previous experimental studies and can be employed to validate CFD or analytical studies currently under development.

Characterizing the hydrodynamics of a fluidized bed is of vital importance to understand the behavior of these multiphase flow systems. Minimum fluidization velocity and gas holdup are two important factors used to understand the hydrodynamics of a fluidized bed. Experimental studies on the effects of bed height on the minimum fluidization velocity and gas holdup were carried out using a 10.2 cm diameter cylindrical fluidized bed filled with 500–600 μm glass beads. In this study, four different bed height-to-diameter ratios were used: H/D = 0.5, 1, 1.5, and 2. Minimum fluidization velocity was determined for each H/D ratio using pressure drop measurements. Local time-average gas holdup was determined using non-invasive X-ray computed tomography imaging. Results show that minimum fluidization velocity is not affected by the change in bed height, while local gas holdup does appear to be affected by the change in bed height.

Search For Information

The first part of the analytical review presents the main directions of application of modern Multisensor systems such as "electronic nose". The review is based on the results of the umbrella search for information on the given words and phrases. Umbrella search has shown its effectiveness in organizing publications in the selected area, reducing the number of repetitive links and unrelated to the topic of the search. The search was carried out on the electronic catalogs of Russian and international search engines. The tendency of growth of interest to the chosen subject for the last 10 years is traced. Traditional research directions for artificial smell systems are noted. After a slight decline in 2005-2010, the share of work to address the challenges of improving quality and safety in all sectors of human activity, including the food industry, agriculture and the environment, is growing. Some solutions in the field of analysis of food products, raw materials, finished products are systematized. A new direction of research using "electronic nose" systems based on sensors of different types of action is discussed. This direction is medicine, while there is a significant breakthrough in the intensity of the use of EN in medical practice for the development of non-invasive diagnostic methods. The positive properties of such devices and approaches are a short study time, minimal sample preparation and recovery of the system after measurement, as well as a small mass/volume of the sample, the possibility of non-invasive diagnosis. The most frequently published research on the results of the use of such systems in the analysis of bioassays, especially interesting non-invasive diagnosis. Among the diagnosed lead direction oncological, gynecological, psychiatric. However, there are single publications and to solve problems in Pediatrics, dentistry, endocrinology and others.
