Published: June 2022

Purpose. A comparative characterization of  clinical forms and outcomes in  patients with Alport syndrome with different types of inheritance.

Characteristics of patients and research methods. We have conducted a retrospective controlled comparative non-randomized single-center longitudinal study that included 60 patients who were admitted to nephrology department of the Russian Children’s Clinical Hospital of the Pirogov Russian National Research Medical University from 2004 to 2020: there were 22 (37%) girls and 38 (63%) boys from 2 to 18 years of age. The median age (Me) was 8,7 [5,4; 13,7] years old. The patients were divided into 2 groups: Group 1 received with cyclosporine A and nephroprotectors, Group 2 received nephroprotectors only.

Results. We identified 75% X-linked, 20% autosomalrecessive, and 5% autosomal dominant types of inheritance among our patients. 45% manifested with combined hematuria with proteinuria, 43% of patients — with isolated hematuria, and 12% — with isolated proteinuria. Hearing damage was detected in 45% of patients, eye damage — in 5%. Nephrotic syndrome developed in 22% of patients, arterial hypertension — in 15%. In patients with X-linked Alportsyndrome, there was a statistically significant(p=0,002) reduction of proteinuria during the first 6 months of treatment in Group 1 compared to Group 2. The difference in proteinuria decrease during therapy is not statistically significant among differenttypes of inheritance. According to survival data, patients with autosomalrecessive inheritance of disease proceed more severely in comparison with other types of inheritance, and this difference tendsto be statically significant(p=0,065).

Conclusion. Timely diagnosis and proper management of patients with Alport syndrome can improve the disease outcome. To determine the prognosis, it is important not only to collect detailed patient’s history and conduct morphological examination, but also to provide genetic testing to determine the type of inheritance.

Authors: Taranushenko T. E. , Parshin N. A. , Vaganov A. A.
Published: June 2022

Intrauterine hypoxia and asphyxia during childbirth are among the leading causes of neonatal deaths in the structure of «Separate conditions arising in the perinatal period» according to the Ministry of Health of the Russian Federation. The main causes of asphyxia are chronic intrauterine hypoxia and acute fetal hypoxia (most often in the intrapartum period). The article observes current data on antenatal and intrapartum risk factors for the development of asphyxia in newborns. Risk factors (modifiable and non-modifiable) triggering intrauterine hypoxia are discussed, as well as methods of management and prevention of asphyxia to prevent the subsequent development of hypoxic-ischemic encephalopathy. The importance of the problem under consideration is due to the need to find promising «tools» for managing neonatal and infant mortality, as well as preventing the long-term consequences of hypoxic brain damage.

Published: June 2022

Purpose.This study analyzes changes in the concentration of elements — magnesium, selenium, strontium — in plasma and RBCs of peripheral blood in parturient women with a history of threatened miscarriage and their newborns. In addition, the difference in cell-membrane permeability indices for each element was determined.

Characteristics of children and research methods. 97 pairs of full-term newborns and their mothers were under observation. The main cohort (Group 1) consisted of 57 mother–child pairs under a threat of miscarriage. The control group (Group 2) consisted of 40 conditionally healthy pairs. Concentrations of chemical elements were determined in plasma and RBCs using mass spectrometry with inductively coupled plasma. Statistical processing consisted of two stages. Initially, the authors determined parameters with a significant change in the concentration of elements, in the presence of a threat of abortion. Then the values of the relationships between all parameters for each element were calculated.

Results.There is an increase in the concentrations of magnesium and selenium in the body of parturient women with a history of threatened miscarriage in comparison with healthy women in labor. The concentration of strontium does not change. In newborns, the concentration of magnesium also increases, and strontium decreases. The concentration of selenium in newborns does not change.

Conclusion. The study findings indicate that the threat of termination of the current pregnancy is accompanied by a change in the elemental status of mothers and their newborns.

Published: June 2022

Purpose. Study of perinatal and neonatal outcomes in newborns born to mothers with preeclampsia.

Characteristics of children and research methods. Perinatal outcomes were analyzed in 559 mother–newborn pairs divided into 2 groups: Group 1 included 200 children to mothers with preeclampsia (143 with moderate and 57 with severe preeclampsia). Group 2 was composed of 359 newborns to mothers with a physiological course of pregnancy. The medical history, features of the course of pregnancy, delivery, and the early neonatal period were analyzed. The condition of newborns was assessed on the Apgar scale at 1 and 5 minutes, the assessment of physical development — using centile tables for full-term and premature newborns (INTERGROWTH-21st), the assessment of neuromuscular and physical maturity on the Ballard scale.

Results. The study showed that children born to mothers with preeclampsia are significantly more likely to have metabolic and hematological disorders, a higher risk of developing infectious and inflammatory diseases, and a direct correlation with the period of manifestation and severity of preeclampsia. The higher occurrence of these conditions and the structure of pathological changes in the neonatal period led to a longer stay of children of this group after birth at newborn intensive care units, and also required observation at the second stage of nursing.

Conclusion. Preeclampsia is a risk factor for neonatal complications. The identified features of adaptation in newborns from patients with preeclampsia and the structure of pathological conditions in the early neonatal period should determine the management tactics and timeliness of treatment and diagnostic measures aimed at improving the provision of medical care to the pregnant woman and subsequently the newborn.

Authors: Kovtun O. P. , Shestak E. V. , Ksenofontova O. L.
Published: June 2022

Transient tachypnea of the newborn is a parenchymal lung disease characterized by respiratory distress in the first hours after birth. The consequences of underestimating the severity of the disease, incorrectly chosen respiratory support technique or its untimely use at the stage of the delivery room are the increase in respiratory failure, transfer to the intensive care unit, and the need for more invasive and expensive methods of treatment. In the study, we set the task to determine the risk factors that allow us to predict the severity of the course of transient tachypnea of the newborn at the stage of the delivery room.

Purpose. Analysis of risk factors that determine the severity of transient tachypnea in the newborn and predicting the tactics of their treatment.

Methods. Retrospective analysis of full-term newborns (n = 201) diagnosed with transient tachypnea of the newborn in 2020, who received any type of respiratory support in the first hours of life.

Results. Most patients with transient tachypnea of the newborn required respiratory support at the stage of the delivery room, which we associate with a combination of risk factors in the history of pregnancy and childbirth. A high incidence of cerebral pathology in the studied newborns was revealed. According to our data, the following factors can be considered as predictors of the severity of the condition and hospitalization in the intensive care unit from the delivery room of patients with transient tachypnea of the newborn: delivery by Casarean section, low Apgar score at 1 and 5 minutes, Downs scale score of 4–5 points, and the need for respiratory support during the delivery room stage.

Conclusions. The results of the study proved a high frequency of transient tachypnea of the newborn registered in full-term infants, allowed to identify risk factors for a severe course of transient tachypnea of the newborn and hospitalization in the intensive care unit.
A change in the type of neurogenic dysfunction as a result of treatment of children with neurogenic bladder subject to surgery for a spinal hernia during the newborn period

Published: June 2022

The most severe consequence of a spinal hernia, affecting the entire life of a person, is a spinal neurogenic bladder. Its symptoms limit the child’s socialization, and the problem of urination needs constant use of various aids. At the same time, despite many studies in neurology, there are no significant shifts in the possibility of restoring the function of urination in spinal patients.

Purpose. The aim of study is to analyze the long-term results of correction of neurogenic bladder in children treated depending on the type of dysfunction with a history of surgery for spinal hernia.

Characteristics of children and research methods. 100 patients with spinal neurogenic bladder aged 1–15 years were examined, urodynamic studies were used. Depending on the state of the detrusor and sphincter, groups of patients were identified, in each of which treatment lasting at least a year was selected.

Results. With a differentiated approach to the choice of therapeutic tactics, depending on the type of neurogenic bladder, the presence of vesicoureteral reflux, urinary tract infection, it was possible to reduce the level of detrusor hypertension, if any, or activate the function of the atonic bladder. Individual options for urinary diversion were developed. With long-term therapy that stabilizes detrusor, a change in the type of neurogenic dysfunction occurred within a year in 98 patients, which required repeated urodynamic examination to change treatment tactics.

Conclusion. Clinical manifestations of spinal neurogenic bladder do not always accurately indicate the type of dysfunction. During the growth of the child, as well as under the influence of treatment, there is a change in the type of neurogenic bladder. Urodynamic examination makes it possible to determine the state of the detrusor and sphincter — and to select a pathogenetically justified treatment option. In case of impaired urination, neurogenic bladder should be corrected with customized self-catheterization. Urodynamics should be controlled in spinal patients at least once a year to correct treatment.

Human resources (HR) is one of the main elements that occupy a very strategic position in an organization or company. For this reason, every company must be able to maintain its employees and strive to increase job satisfaction. This study aims to analyze the effect of work-family conflict and social support on job satisfaction. This study also examines the moderating role of social support on the effect of work-family conflict on job satisfaction. This research was conducted at the State Savings Bank (BTN) located in Denpasar City, Bali. The sample in this study were permanent employees of BTN in Denpasar, Bali, totalling 103 people. The data analysis technique used is Moderated Regression Analysis (MRA). The results showed that work-family conflict had no significant effect on job satisfaction, while social support had a positive and significant effect on job satisfaction. Social support is a moderating variable of the relationship between work-family conflict and job satisfaction. The type of moderating role of the social support variable is the quasi moderator. Specifically, social support weakens the effect of work-family conflict on job satisfaction.
The performance effect due to varying network topologies on a software defined network employing the k-shortest path
Authors:   Faculty of Computer Science and Information Technology, Universiti Putra Malaysia, Seri Kembangan, Malaysia, et al. Linsheng
Published: June 2022

Packet routing has always been an issue that affects network performance. The traditional protocol is known to work with local information and thus not able to produce a global optimal decision. In the software-defined network (SDN), its centralized controller obtains unified access to the entire network topology information and has the ability to partially solve traditional network packet forwarding problems. SDN controller uses the Dijkstra algorithm to find the shortest path calculated from the source node to the destination node. However, constraints such as the need to bypass the node which has a high rate of failure exist to prevent the Dijkstra algorithm from meeting this demand. In practice, we need not only consider the shortest path but also consider the second short path, the third short path, and so on. K-shortest paths algorithm discovers a set of paths ordered in the most optimal, optimal, and suboptimal, has a very wide application is integrated into SDN controller to handle routing functionality. In this study, instead of only the number of hops, bandwidth and delay are adhered to within the k-shortest path to select the final route. Under this circumstance, different topologies are examined in response to network bandwidth and packet delay. The experiment shows that tree topology is best suited for improving bandwidth while simple topology for reducing delay.

Authors: Васильев Ю.Б.
Published: June 2022

Plasmon excitations in two-dimensional electron systems in an AlGaAs/GaAs heterojunction containing a layer of self-organizing antidots at the heterointerface are experimentally studied. In a magnetic field, in the terahertz absorption spectra obtained by Fourier spectroscopy, along with the cyclotron resonance, a magnetoplasmon mode is observed. With an increase in the magnetic field, an extreme decrease in the width of the magnetoplasmon line occurs, which can be explained by the localization of plasmons by the magnetic field in a random array of antidots.

Published: June 2022

Experimental investigation of two-dimensional GaN layer transformation into three-dimensional islands (2D-3D transition) under temperature increase in ammonia flow has been performed by the reflection high energy electron diffraction method. The results were explained in the framework of the previously developed kinetic model and the Mariette equilibrium model. It is shown that with increasing temperature due to the desorption processes of NH2 particles the surface energy increases, the 3D surface state becomes energetically favorable and 3D islands are formed. With further increase in temperature due to dissociation processes of NH2 and NH particles, the surface energy decreases and the 2D surface state becomes energetically favorable again, resulting in 3D islands being converted back to 2D layer.

The results of experimental studies on the synthesis by molecular-beam epitaxy of AlGaAs nanowires with InGaAs quantum dots are presented. It was shown that, as in the case of the InP/InAsP material system, the formation of predominantly two objects is observed in the body of AlGaAs nanowire: InGaAs
quantum dot due to axial growth and InGaAs quantum well due to radial growth. It is important to note that the grown nanostructures were formed predominantly in the wurtzite crystallographic phase. The results of the grown nanostructures physical properties studies indicate that they are promising for moving single-photon sources to the long-wavelength region. The proposed technology opens up new possibilities for integration direct-gap III−V materials with a silicon platform for various applications in photonics and quantum communications.

This paper presents the results of studying the growth of InGaN layers with a high (50-80%) indium content by molecular beam epitaxy with nitrogen plasma activation on sapphire substrates with GaN/AlN buffer layers. It is shown that the processes of dissociation and phase separation of the growing InGaN layer, which occur in structures with an indium fraction of about 50%, cannot be suppressed due to the transition to a lower temperature growth (470°C - 390°C) without significant degradation of the crystalline quality of the formed structures and a sharp decrease in their emissivity. As an alternative approach to suppressing diffusion processes on the growth surface and, as a result, obtaining homogeneous InGaN layers with an [In] content of ~ 50%, high-temperature (470°C) growth under highly nitrogen-enriched conditions (flux ratio III/V ~ 0.6) was tested. The InGaN layers grown in this way show intense photoluminescence, while at the same time showing no signs of phase separation according to X-ray diffraction data. This is critically important for the possibility of implementing optical amplification and laser generation in such structures in the red region of the spectrum and in the immediately adjacent part of the near infrared region.

In this work, we conduct research of spectral and power characteristics of quantum cascade lasers (QCLs) based on a GaAs/Al0.15Ga0.85As active region emitting at 2.3 (A), 3.2 (B) and 4.1 (C) THz. The QCL devices had a double-metal Au waveguide and operated in pulsed mode with 1.5–9 us pulses at 20 Hz repetition rate. Using the integral output power curves measured with different pulse durations, we consider the potential mechanisms of QCL temperature degradation using Arrhenius plots. Moreover, we present the spectra of the lasers measured at fixed operating points for devices A, С and with current scanning for device B in a wide temperature range from 5 to 120 K. We hope that our results will prove useful for research concerning QCL maximum operating temperatures.

Published: June 2022

Current work reports the manufacturing and electrical characteristics of organic field-effect transistors in the top-contact bottom-gate configurations utilizing solution - processed poly (3-hexylthiophene) films as an active semiconducting layer and thermoplastic polyurethane as gate insulator. A spin coating chemical polymerization technology and an electrospinning tool for polymeric mats production were used to prepare uniform organic thin films with controlled thickness from their solutions. Commercially available flat glass slides were used as the starting substrate. To form the gate electrode a thin layer of metal such as gold (Au) or silver (Ag) was deposited on the glass surface substrates by thermal evaporation through a shadow mask. Thermoplastic polyurethane insulating films with different thicknesses were electrospun from precursor solution on the substrates with Au or Ag electrodes. Patterned Au and/or Ag drain and source electrodes were deposited directly on the surface of as - fabricated poly(3-hexylthiophene) organic semiconductor layer. We used two kinds of metals that have different work functions and their combinations to investigate the influence of the source, drain and gate electrode materials on the output characteristics of fabricated organic thin film transistors. All fabricated of organic field-effect transistor devices showed typical p-type channel characteristics. Additionally, the effects of thermoplastic polyurethane gate dielectric thickness as well as the influence of processing parameters on electrical performances of organic field-effect transistors fabricated were also investigated. Results show that all developed transistors exhibit good and stable performance up to a relatively high drain voltage of ~50 V and the drain-source current up to ~0.5 μA. Keywords: organic field-effect transistors, P3HT organic semiconductor, TPU gate dielectric, electrical characteristics.
Evaluation of needs and preferences that arise during the course of the medical history of people with people living with chronic heart failure in Austria: A qualitative analysis based on semi-structured interviews. (Preprint)

Published: June 2022

BACKGROUND

In the industrialized world, between one and two per cent of adults worldwide are affected by Chronic Heart Failure (CHI) - i.e. in Austria, between 70,000 and 140,000 affected people can be assumed.

OBJECTIVE

The project aimed to identify the subjective needs and preferences of people affected by CHI in relation to interventions to empower them in different stages of the disease.

METHODS

Semi-structured interviews in different settings (clinical care, outpatient care, rehabilitation clinic, primary care, home care) were conducted with twelve (58% women) individuals. The focus was on other interventions for managing the condition, their content, and modalities regarding the various stages of the disease.

RESULTS

During the evaluation, a psychological process for internalising the diagnosis became visible. During the first year, the patients tried to generate knowledge about the disease and seek support. After this phase, people living with CHI got used to the condition and learned to deal with it. CHI was no longer perceived as an immediate threat and receded into the background of everyday life. In the beginning, the most important thing for them was theoretical information about heart failure (e.g. how the heart works, causes, complaints and symptoms of CHI) and how to deal with medication. In further progress, pragmatic questions about health-oriented behaviour in everyday life came to the fore.

CONCLUSIONS

To meet the needs of the people concerned educational measures such as education programmes, brochures and experiences of people with CHI were recommended at the beginning; afterwards, a telerehabilitation and thematically appropriate group courses (e.g. exercise classes, self-help groups, etc.), as well as a “lifestyle” patient app, can be considered for empowerment.

Published: June 2022

Access surgery is an important procedure performed during endodontic treatment as it allows the dental surgeon to access the pulp chamber and locate the root canals. During this procedure, spherical and conical stem diamond tips with inactive end are used to remove caries, establish a contour shape and refine the walls of the pulp chamber. Inserts coupled to dental ultrasound are constantly used to help refine the floor of the pulp chamber. However, depending on the vibration provided by the ultrasound device and incorrect handling of the insert, it will cause depressions and perforations in the floor of the pulp chamber. Given the context, this research aims to assess the quality of pulp chamber floor refinement by different ultrasound devices. This is a research with the principle of applied investigation, qualitative and quantitative approach, with an exploratory character, where 100 upper and lower human molars will be selected distributed in 4 groups, where the floor refinement will be carried out with TRA 24 ultrasound insert ( Trinks, São Paulo, Brazil) however, coupled to different ultrasonic devices: G1 (No. 25) CvDentus, G2 (No. 25) Sonic Plus Ecel, G3 (No. 25) Sonic Air Scaler and G4 (No. 25) Denshine . After completion of the access surgery, a visual inspection will be performed to assess the presence of excessive wear, depressions and identification of root canals. The results were tabulated, analyzed and it was found that there was no significant difference between the groups regarding the presence of excessive wear, depressions and identification of root canals. Thus, it is possible to conclude that all ultrasonic devices showed satisfactory results in the refinement of the floor of the analyzed teeth.

Published: June 2022

The study focused on identifying the morphological properties found in Kisukuma nouns which make nouns different from other Bantu languages. The study was guided by distributed morphology theory developed by Halle and Marantz (1993). The study was purely qualitative approach whereby data were collected through questionnaires, documentation review as well as focused group discussion. Ten respondents who were the native speakers of the Kimunantunzu dialect of Kisukuma age of forty-one to eighty were chosen. The study found that the interrelation between morphology and syntax in Kisukuma nouns can be analyzed without ignoring the morpho-syntactic properties. Moreover, it was found that the agreement properties are triggered by the nouns. That is to say, nouns determine what other elements could co-occur with them and bring a meaningful sentence or phrase. Also affixes are very important in forming nouns in Kisukuma just like in other Bantu languages. The researcher recommends that more interrelation studies to be investigated on the other levels of linguistics as well as distinction among the dialects of Kisukuma.

Published: June 2022

Abstract— Alcohol detection system is developed for road transportation safety in smart city using Internet of Things (IoT) technology. Due to the rapid increase of vehicles on roads, the probability of road accidents is rising steeply. Drunk driving is considered to be a major cause of road accidents throughout the world. The main aim of this project is to develop a system that would detect the amount of alcohol that is consumed by the driver of the vehicle. This system discusses development and live-performance test of the prototype of drink and drive situation detection and alert cum vehicle control system to minimize road mishaps and enhance public safety on road. The model is developed using Arduino Uno and alcohol detection sensor (MQ-3) as its major components. As a safety measure, when the level of alcohol crosses a permissible limit, Vehicle Control System is triggered to lock ignition or stop the fuel inflow to the vehicle. Additionally, ‘alert SMS’ indicating drunk driver location, tracked by onboard GPS receiver, along with vehicle number is communicated remotely to the authorized people (family). The deployment of this system will help in reducing the incidence of drunk driving related road accidents in smart cities.

These tall structures include residential apartment, commercial and semi-commercial apartment. Since the provision of these buildings have a larger area of construction, but constructed over less area. In analysis stage of the structure, significant characteristics like vertical load, horizontal load, superstructure design, foundation design takes place. But before that the architecture planning over the larger area has proposed. The selection of area of construction in this preliminary stage has not sufficient on comparing with structural design configurations and soil parameters is an important part should takes place before the planning of the construction area.

Abstract— This invention relates to the field of electronics engineering and mechanical engineering more particularly to reduce accidents along with preventing operators from driving a motorized vehicle in watercourses overflow conditions. Nearly 1/2 of all flood deaths rise in vehicles. Most of those deaths take area while humans power into flooded dual carriageway dips or low drainage areas. A low-water crossing is wherein a road, without a bridge, dips through a usually dry creek mattress or drainage area. Motorists who try to pass those flooded low-water crossings are setting themselves, their vehicles, and any other occupants of their vehicles at deadly risk. In a preferred embodiment, once the system determines the speed of the water flow & depth of the water flow then it starts to give signals in the form of red for danger and green for neutral conditions. On the basis of this driver, a person can think about crossing the flooded bridge. Keywords— Bridge, River, Drowning, Overflow, Rainfall, Flood Problems, India
Experimental Evaluation on the Performance of Cold Mix Asphalt in Comparison with Hot Mix Asphalt for BC Layer
Authors: Kumar Santosh
Published: June 2022

Abstract— Hot Mix Technology is used from many years in the construction of bituminous layer. It basically involves heating of aggregates and bitumen, mixing and laying of the mixture at a high temperature around 120°C - 165°C. Though it is well suited for all the types of roads because of its good performance, it has several dis-advantages such as degradation of environment, it consumes lot of energy, problems due to hardening of asphalt, and it cannot be laid in cold region and during rainfall season. There is an increasing demand for the Cold Mix Asphalt (CMA) due to its several advantages and also it is gaining importance nowadays specially in the cold areas. The main advantage is the elimination of heating of aggregates and bitumen; instead emulsion can be used in producing the bituminous mix. Also, Cold Mix Asphalt is ecofriendly and consumes less energy. In the present study, the main objective is to check the feasibility of cold mix asphalt for Bituminous Concrete layer. For Cold Mix Asphalt bitumen emulsion of grade SS-2 is used. The Marshall Test is carried out on CMA and Hot Mix Asphalt (HMA) by varying bitumen emulsion and bitumen content respectively.. The results obtained are comparable with Hot Mix Asphalt. Hence Cold Mix Asphalt is feasible for BC layer. Keywords— Cold Mix Asphalt; Hot Mix Asphalt; Marshal Test; BC Layer; Emulsion;

Abstract: The signal system designed here is intended to raise metal rods from the underground of road when red signal is energized. This scheme is adapted to restrict the road traffic strictly. When the red light turned in to green, automatically the metal rods will be lowered to below the road level. In addition after stopping the traffic, pedestrians are allowed to cross the road, for which an automatic announcement will be made to alert them. Since it is a prototype module, basic theme is presented for single road, but for real time applications it can be implemented for all sides of the cross roads . The demo module is constructed with single signal post which contains red, green & yellow signals. The main processing unit constructed with 89C2051 controller chip is programmed to energize indicators one after another automatically with specific timings. Once the system is energized, initially green indicator will be glow, after some time green indicator will be switched off and yellow indicator will be glown, and then red indicator will be energized. As long as red indicator remains in glowing condition, walking person symbol simulated with green LED’s will be flashed continuously until the green indicator glows. During red indicator on, metal rods remains above the road level, after that these rods will be lowered automatically. DC motor is used to raise and lower the metal rods moving mechanism. The moving mechanism is constructed with Rack & pinion. Voice record cum playback unit designed with ISD1820 chip is used to make an auto announcement such that during red signal condition “now pedestrians can cross the road” will be announced automatically. This message will be repeated until the red signal turned off. H Bridge IC is used to drive the DC motor. Especially this system is very useful for school zones.

Abstract— Energy is one of the major inputs for economic development in any country in the world. In developing countries, energy is a major contributor and huge investment is required to meet the energy needs in such countries. India has been a dynamic country since its inception. There are many industries here where electricity consumption is mostly 60% to 65%. The main objective of this paper is to maintain optimum energy throughout the organization by focusing on those energy points to reduce current and future energy costs and improve power quality. This paper presents “To Control Grid Power Factor and Increase Energy Efficiency in Thermal Power Plant through Energy Audit”. In this energy audit analysis is done for a month to improve the power factor close to unity by the automatic reactive power control panel to maintain the grid p. f. to 0.99 by compensating for the required reactive power from the grid-connected alternator. . Energy audits will help you understand the energy and fuel systems used in any industry, and identify the various areas where energy loss can occur and where it has scope. The proposed approach is validated by considering the case study.

Published: June 2022

Abstract— The Indian Ocean Tsunami on 26 December 2004 resulted into massive destruction to coastal communities with more than 3,00,000 people losing their lives, and causes severe damage to buildings, bridges and other infrastructure. Such catastrophic event made the coastal community realize the need for the preparedness against initial ground shaking and subsequent effects followed by Tsunami. The current study focuses on progressive collapse analysis of 10 storey reinforced concrete frame with bracing and shear wall subjected to different Tsunami forces. The Tsunami forces were calculated according to the guidelines of FEMA P-646, ASCE 7-16. The December 26, 2004 Tsunami parameters on the coast of Tamilnadu were considered for the evaluation of effect of Tsunami forces on structure. To simulate similar conditions structure was designed according to Zone-III and was subjected to Tsunami forces for the 12m, 9m and 6m runup. This study consists of two parts: 1) The calculation of Tsunami forces and application of forces on structure and 2) Progressive collapse analysis of structure by removing the vertical load bearing critical members due to Tsunami forces. The progressive collapse analysis was carried out with the help of commercially available software named ETABs 16. The critical members were removed. The analysis was carried out by referring General Services Administration (GSA-2013, Revised 2016) and Unified Facility Criteria - Department of Defense (UFC - DoD-2009, Revised 2016) guidelines. From the analysis results it was found out that structure becomes critical when Bracing and Shear wall were oriented normal to the flow of tsunami. Upon performing the progressive collapse analysis of structure which was found to be critical due to Tsunami forces reveals that the joint at which the vertical member was removed did not exceed the acceptance criteria of collapse prevention. Hence structure was able to redistribute the unbalanced gravity load and thus prevents the progressive collapse of structure.

Published: June 2022

Abstract: Agriculture is the main occupation for the people of Jammu & Kashmir. About 65 per cent of the people are directly or indirectly dependent on agriculture and allied activities for their livelihood. Agriculture and its allied activities are the predominant sectors of the economy of Jammu & Kashmir. The cropping land use in the state also underwent drastic changes which led to a decrease in area under food crops and an increase in area under cash crops/plantation agriculture. The study of this shifting land use was necessary for the sustainable agriculture of the state. Knowledge of cropping land use helps in maximization of productivity and conservation of land. The study tried to assess the cropping pattern of land use and land change dynamics, the land use and land cover change among different land-use classes and to study the extent of productive and unproductive land-use patterns in Jammu & Kashmir. The study has revealed a major shift of land from the desirable to undesirable land-use classes. The area under the three major food crops (Paddy, Maize and wheat) grown in the state has decreased at the state level though with regional variations, it has increased in some districts as well. But the area under paddy recorded a decline in all the districts and the area under orchards has registered highly positive growth in all the districts of Jammu & Kashmir.
