An Investigation of the Impact of Occupational Stress on Mental health of remote working women IT Professionals in Urban Bangalore, India

The COVID-19 pandemic has influenced various aspects of our lives and triggered many long-term consequences. The actual well-being of women IT employees is in danger due to the prolonged period of work from home as the pandemic has influenced individuals differently across the world. Physical distancing, dread, vulnerability, and a continued period of remote working has prompted an enormous number of women in the IT sector to experience challenges to emotional well-being. Work-related pressure is one of the major sources of stress in the modern working environment. Stress and unfavorable working conditions have been connected to low efficiency, truancy, and increasing rates of mishaps in and out of work. This is largely due to ailments, substance abuse, and family issues experienced by a large number of work-from-home women software company employees. Extended period of work from home can disturb women and their mental health as they try to strike a work-life balance. The purpose of this research is to examine the impact of occupational stress factors on the mental health of the women software professionals working remotely in urban Bangalore during the COVID-19 pandemic. The exploratory factor analysis identifies that Workload, Job Insecurity, Poor Work Environment, Personal Problems, and Lack of Structure as the main five factors of occupational stress while working from home for women IT employees in urban Bangalore. Multiple regression analysis undertaken in the study indicates that the relationship between the five factors of Occupational Stress and Mental Health is negatively significant with an inverse relationship

In vitro culture of Piper attenuatum Ham. (Piperaceae): Callus induction and plant regeneration

Callus induction and plant regeneration of Piper attenuatum was achieved from stem explants in Murashige and Skoog and Gamborg's basal media supplemented with 2,4-dichlorophenoxyacetic acid, indole-3-acetic acid, Kinetin, benzyladenine and palmyarh (Borassus flabelliferl endosperm extract. Root induction was obtained from stem explants in Murashige and Skoog medium supplemented with a-naphthaleneacetic acid, b-naphthoxyacetic acid, indole-3-acetic acid, benzyladenine, kinetin and coconut water. Shoot development was achieved in in vitro rooted stem segments planted in Murashige and Skoog's medium supplemented with indole-3-acetic acid, benzyladenine and also in indole-3-acetic acid and kinetin. The plantlets were successfully established in soil. This is the first report of in vitro culture of P. attenuatum. &nbsp

Vehicle sideslip angle estimation using Kalman filters: modelling and validation

The knowledge of the vehicle sideslip angle provides useful information about the state of the vehicle and it is often considered to increase the performance of the car as well as to develop safety systems, especially in the vehicle equipped with Torque Vectoring control systems. This paper describes two methods, based on the use of Kalman filters, to estimate the vehicle sideslip angle and the tire forces of a vehicle starting from the longitudinal and yaw velocity data. In particular, these data refer to on-track testing of a Range Rover Evoque performing ramp steer maneuvers at constant speed. The results of the sideslip estimation method are compared with the actual vehicle sideslip measured by a Datron sensor and are also used to estimate the tire lateral forces

Stromal Interferon-γ Signaling and Cross-Presentation Are Required to Eliminate Antigen-Loss Variants of B Cell Lymphomas in Mice

To study mechanisms of T cell-mediated rejection of B cell lymphomas, we developed a murine lymphoma model wherein three potential rejection antigens, human c-MYC, chicken ovalbumin (OVA), and GFP are expressed. After transfer into wild-type mice 60–70% of systemically growing lymphomas expressing all three antigens were rejected; lymphomas expressing only human c-MYC protein were not rejected. OVA expressing lymphomas were infiltrated by T cells, showed MHC class I and II upregulation, and lost antigen expression, indicating immune escape. In contrast to wild-type recipients, 80–100% of STAT1-, IFN-γ-, or IFN-γ receptor-deficient recipients died of lymphoma, indicating that host IFN-γ signaling is critical for rejection. Lymphomas arising in IFN-γ- and IFN-γ-receptor-deficient mice had invariably lost antigen expression, suggesting that poor overall survival of these recipients was due to inefficient elimination of antigen-negative lymphoma variants. Antigen-dependent eradication of lymphoma cells in wild-type animals was dependent on cross-presentation of antigen by cells of the tumor stroma. These findings provide first evidence for an important role of the tumor stroma in T cell-mediated control of hematologic neoplasias and highlight the importance of incorporating stroma-targeting strategies into future immunotherapeutic approaches
