Stereotypies in adults: a systematic review

Stereotypies are abnormal involuntary non-goal-directed movement patterns or vocalisations which repeat continuously in the same fashion over a period of time and on multiple occasions and are typically distractible. Stereotypies are common in both children and adults, but they are extensively reviewed only in children. There are very few studies, mainly in the form of case reports and case series, focusing on stereotypies occurring in adults as part of different neurological disorders. In adults, stereotypies can be both physiological and pathological. Common physiological stereotypies in adults are leg shaking, face touching, playing with pens or hair, nail biting, hand tapping, foot tapping, and body rocking. Pathological stereotypies in adults are associated with a variety of neuropsychiatric conditions like neurodegenerative disorders, viral encephalitis, autoimmune encephalitis, stroke, psychiatric illness, and drug use. In this review, we focus on the various causes of stereotypic movements in adults, and their pathophysiology, clinical manifestations, and treatment

Finite element analysis of laterally loaded piles in sloping ground

The available analytical methods of analysis for laterally loaded piles in level ground cannot be directly applied to such piles in sloping ground. With the commercially available software, the simulation of the appropriate field condition is a challenging task, and the results are subjective. Therefore, it becomes essential to understand the process of development of a user-framed numerical formulation, which may be used easily as per the specific site conditions without depending on other indirect methods of analysis as well as on the software. In the present study, a detailed three-dimensional finite element formulation is presented for the analysis of laterally loaded piles in sloping ground developing the 18 node triangular prism elements. An application of the numerical formulation has been illustrated for the pile located at the crest of the slope and for the pile located at some edge distance from the crest. The specific examples show that at any given depth, the displacement and bending moment increase with an increase in slope of the ground, whereas they decrease with increasing edge distance

EFFECT OF AAHAR AND VIHAR IN NCDS W.S.R TO MODERN ERA

NCD is medical conditions that is not caused by infectious agent but are caused as a direct result of diet, life style and environmental factors. NCDs can refers to chronic diseases which last for long periods of time and progress slowly such as autoimmune disease, cardiovascular diseases, metabolic diseases and chronic kidney diseases. NCDs are leading cause of death in the world representing 63% of all annual deaths. The major cause of NCD is eating unhealthy foods like food so much sweet, high salt, high fat, other junk food and fruits persevered with chemical fertilizer and drinking excess amount of alcohol. Doing no physical activity have increased working hours, high stress level, are major cause of NCDs.Ayurveda is science of life it is mentioned that the 3 pillars of healthy and long life are proper Aahar, Nidra, Bhrahmcharya of our body. Our diet is an essential factor for the formation of body. Charak says that consuming improper diet in improper way is the main cause of disease this is explained under Ashtaaharvidhivisheshayatan, Viruddhaahar. Use of incompatible food leads to skin disorder, GIT disorder, Diabetes, obesity, hence these should be avoided. Ayurveda imphasizes regulation of Aahar Vihar in the form of Ashtaaharvidhivisheshayatan, Dincharya, Ritucharya. Ayurveda can definitely yield reliable efficacious result when applied to all manner of chronic diseases

Taylor\u27s slope stability chart for combined effects of horizontal and vertical seismic coefficients

Design standards and codes of practice on earth slope stability often recommend the pseudo-static method of analysis for determining the factor of safety of a slope subjected to seismic forces. In most pseudo-static methods of analysis, the horizontal seismic force is considered without due weightage to vertical seismic force. In the past, Taylor\u27s stability chart for a homogeneous cohesive-frictional soil slope has been extended to consider the effect of horizontal seismic force only. In this paper, an attempt is made to develop an analytical formulation considering both horizontal and vertical seismic forces in order to estimate the factor of safety of the homogeneous, cohesive-frictional soil slopes with simple profiles using Taylor\u27s stability chart. The analytical formulation is based on the friction circle method, which is one of the methods of static slope stability analysis. Several field cases have been analysed considering slope geometry, soil properties and seismic loading conditions so that Taylor\u27s stability chart can be routinely used by practising engineers considering the effects of both horizontal and vertical seismic forces. An illustrative example is included in order to explain how practising engineers can use the graphical presentations developed in this paper as the design charts for stability analysis. This illustrative example has also been solved using Plaxis 2D, a commercially available finite-element software, as a comparison

The Elements of Supernatural and Magic Realism in Toni Morrison’s Beloved

The present research paper is a study of the elements of Magic Realism and the supernatural elements in the novel, Beloved by the Nobel laureate novelist Toni Morrison. The term Magic Realism was originally applied in the 1920s to the school of surrealist German painters and was later used to describe the process fiction of writers like George Luis Burges, Gabriel Garcia Marquez, and Salman Rushdie etc. These writers weave a sharply etched realism representing ordinary events and details together with fantastic and dream-like elements, as well as with material derived from myth and fairy tales. The German critic Franz Roz introduced the concept of Magic realism in 1920 and it was first used in paintings. The term was introduced in the book Post-expressionism, Magic Realism: Problem of the Most Recent European Paintings in 1925. The purpose here is to analyze the elements of magic realism in the novel, Beloved. We can see supernatural elements in Sethe’s house that bring chaos by haunting everyone through its mysterious presence, and making Sethe’s both the sons Howard and Buglar run away. It appears to be the ghost of a baby which was murdered by Sethe. The ghost causes the things in the house to break and shake mysteriously. In magic realism fiction the ghosts are the central characters generally. In the novel Beloved Morrison has portrayed the ghost as a living person. Thus, the dominance of a unique, mystical and gloomy atmosphere can be seen throughout the novel

Stability analysis and design charts for a sandy soil slope supporting an embedded strip footing

In several field situations, especially in the hilly terrains, the construction of footings on slopes becomes essential. The factor of safety of a slope supporting a loaded footing on the crest is dependent on the position of the footing from the crest edge. Most studies in the past have focused on analysing the bearing capacity and settlement behaviour of a footing resting on a slope crest, but foundations in most infrastructure projects are usually built at some depth below the ground surface. Therefore, the availability of some form of design charts for determining the factor of safety of a slope supporting an embedded footing will be highly useful for the practising engineers. In the current work, the finite element analysis of a sandy soil slope supporting an embedded footing was carried out using the Plaxis 2D, a finite element-based commercial software, in order to examine the effect of slope geometry, soil properties, and footing locations on the stability of slope in terms of factor of safety. The results of the analysis show that the factor of safety of the slope increases with an increase in the footing edge distance, footing depth and soil relative density, but it decreases with an increase in the slope angle and applied pressure on the footing. Some design charts have been developed along with an illustrative example to explain how these charts can be used by the practising engineers

THE EFFECT OF UPANAHA SWEDA AND VATARI GUGGULU IN THE MANAGEMENT OF JANUSANDHIGATA VATA (KNEE OSTEOARTHRITIS): A COMPARATIVE STUDY

Every man derives the happiness and benefit of his life through locomotion i.e., using his joints. For the minute if he loses this power of locomotion he not only feels himself a miserable creature but also becomes a burden both of his family and society. The loss or reduction in his locomotive power is due to dysfunction of the joints causing an impediment to his movements. If not treated in time, the disease makes man disable. Sandhigata Vata is most common articular disorder. It is a type of Vata Vyadhi which mainly occurs in Vriddhavastha, due to Dhatukshaya. Sandhigata Vata can be correlated with osteoarthritis (OA) which is one such chronic, degenerative, inflammatory disease and has a great impact on the quality of the life of an individual. Different modalities of treatment have been explained in the classics to tackle the condition effectively. The present study was aimed to assess clinically the effect of Upanaha Sweda and Vatari Guggulu in the management of Janusandhigata Vata. In this study total 42 patients were divided in 2 groups. In Group A, patients were treated with only Upanaha Sweda and other group patients were treated with Upanaha Sweda and Vatari Guggulu. Results obtained were analyzed for statistical significance which shows group B in which Vatari Guggulu and Upanaha Sweda were given, was more effective in bringing relief in signs and symptoms of Janusandhigata Vata

Liquefaction proneness of stratified sand-silt layers based on cyclic triaxial tests

Most studies on liquefaction have addressed homogeneous soil strata using sand or sand with fine content without considering soil stratification. In this study, cyclic triaxial tests were conducted on the stratified sand specimens embedded with the silt layers to investigate the liquefaction failures and void-redistribution at confining stress of 100 kPa under stress-controlled mode. The loosening of underlying sand mass and hindrance to pore-water flow caused localized bulging at the sand-silt interface. It is observed that at a silt thickness of 0.2H (H is the height of the specimen), nearly 187 load cycles were required to attain liquefaction, which was the highest among all the silt thicknesses with a single silt layer. Therefore, 0.2H is assumed as the optimum silt thickness (topt). The silt was placed at the top, middle and bottom of the specimen to understand the effect of silt layer location. Due to the increase in depth of the silt layer from the top position (capped soil state) to the bottom, the cycles to reach liquefaction (Ncyc,L) increased 2.18 times. Also, when the number of silt layers increased from single to triple, there was an increase of about 880% in Ncyc,L. The micro-characterization analysis of the soil specimens indicated silty materials transported in upper sections of the specimen due to the dissipated pore pressure. The main parameters, including thickness (t), location (z), cyclic stress ratio (CSR), number of silt layers (n) and modified relative density (Dr,m), performed significantly in governing the liquefaction resistance. For this, a multilinear regression model is developed based on critical parameters for prediction of Ncyc,L. Furthermore, the developed constitutive model has been validated using the data from the present study and earlier findings

An experimental study on micro-structural and geotechnical characteristics of expansive clay mixed with EPS granules

© 2020 Pavement structures constructed on the expansive soil subgrade experience a higher upward pressure compared to any other subgrade material. The upward pressure is caused due to high swelling and shrinkage characteristics of expansive clay soil. The present study has investigated and identified the mechanisms by which a remolded expansive soil can be modified to reduce the upward pressure and swelling (heave). To achieve this, a lightweight, environmentally friendly, and high pressure resistive expanded polystyrene (EPS) granules have been used with expansive soil s from three different locations of Madhya Pradesh state, India. The study has been performed to understand the swelling and strength characteristics of soil with and without the use of EPS (density = 21.6 kg/m3) as per ASTM specifications. The chemical and microstructural components of the expansive soil were investigated using autotuned total reflectance Fourier transform infrared (ATR-FTIR), X-ray diffraction (XRD), and scanning electron microscope (SEM). Several laboratory experiments, including optimum moisture content, maximum dry unit weight, grain-size distribution, liquid limit, plastic limit, shrinkage limit, free swell index, unconfined compressive strength, and pressure swelling tests were carried out on the statically compacted expansive clay soil specimen with and without EPS (0.25%, 0.50%, 1.00%). The maximum addition of EPS was considered as 1% as the very high expansion was observed, and beyond this, further addition of EPS was not feasible. The results show that the swelling pressure, expansion percentage, and time rate of swell decrease, whereas the unconfined compressive strength (UCS) increases with the addition of EPS. The inclusion of EPS in expansive clay soil exponentially reduced the heave and the upward pressure, whereas the maximum UCS was observed at 0.5%

Influence of soil fabric on dynamic properties of sand: An experimental study

Natural field sites originate under the action of external sources such as rivers, wind, or marine environments. These sources are responsible for constituting a variety of soil fabrics, which ultimately modify the deformation characteristics. Additionally, the dynamic properties of a site present the characterization of a region and have been profusely utilized by field engineers and researchers. In the present study, the dynamic properties of soil specimens have been evaluated for specimen preparation techniques, namely, air pluviation (AP) and water sedimentation (WS). The cyclic triaxial tests were conducted on the strain-controlled consolidated undrained specimens at a frequency of 0.1 Hz. This frequency has been used in several studies to replicate earthquake or liquefaction scenarios. The calculation of shear modulus (G) and damping ratio (D) was performed using symmetric hysteresis loops generated through cyclic loadings. The outcomes suggest that the specimen prepared using the WS technique possesses a larger shear modulus value than AP ones. The reason behind this observation was the lower degradation characteristics of the WS-prepared specimens. Additionally, the liquefaction susceptibility of the specimens has been noticed for different specimens. © 2023 ISEC Press
