Towards Cost Modelling for Rapid Prototyping and Tooling Technology-Based Investment Casting Process for Development of Low-Cost Dies
No full textIn precision manufacturing, selecting the most economically viable process is essential for low-volume, high-complexity applications. This study compares the machining process (MP), conventional investment casting (CIC), and rapid prototyping (RP) through a mathematical cost model based on the activity-based costing (ABC) approach. The model captures detailed cost drivers across design, logistics, production, and environmental dimensions. Results show that MP incurs the highest production cost (94.45%) but minimal logistics (3.43%). CIC bears the highest total cost and significant production overhead (93.2%), while RIC achieves the lowest total cost, driven by major savings in production (84.6%) and labor. Although RIC has slightly higher logistics than MP, it demonstrates superior economic efficiency for small-batch, high-accuracy production. This study provides a unified quantitative framework for cost comparison and offers valuable guidance for manufacturers aiming to enhance efficiency, sustainability, and profitability across diverse fabrication strategies

No full textLeft out: essays on suburbia
No full textThis collection of essays examines the aesthetic of uniformity and order prevalent in planned, suburban housing developments. It utilizes both personal experience and research to examine the effect this aesthetic has on the suburbanite. It relates stories from the author�s childhood that attempt to illustrate the homogenizing effects of the suburban aesthetic and relates the author�s current sensibilities, attempting to relate them to his upbringing.Autobiographical essays
Effectiveness of a peer-delivered, psychosocial intervention on maternal depression and child development at 3 years postnatal: a cluster randomised trial in Pakistan
No full textMaternal depression has a recurring course that can influence offspring outcomes. Evidence on how to treat maternal depression to improve longer-term maternal outcomes and reduce intergenerational transmission of psychopathology is scarce, particularly for task-shifted, low-intensity, and scalable psychosocial interventions. We evaluated the effects of a peer-delivered, psychosocial intervention on maternal depression and child development at 3 years postnatal

No full textNicotine, in the form of tobacco smoking, is the most commonly abused drug throughout the world. It contributes to the harmful tobacco smoking habit leading to high morbidity and mortality throughout the world. The drug has addictive properties and causes drug dependence. Apart from these effects, nicotine alters a number of metabolic pathways such as lipid profile and glucose homeostasis leading to increased risk of cardiovascular diseases. Present study investigated the metabolic and behavioral effects of nicotine in stressed mice. For this purpose adult male mice were subjected to chronic nicotine treatment(3.08 mg/100 ml in drinking water) for 3 weeks followed by forced swim test (FST) and serum glucose, lipid profile and tryptophan were investigated. When swim stressed mice were compared with chow control, it was found that serum glucose (P<0.001), total cholesterol (P<0.001), triglycerides (P<0.01), and LDL cholesterol (P<0.01) were increased. Similarly glucose concentration (P<0.05), total cholesterol (P<0.05), triglycerides (P<0.01) and LDL cholesterol (P<0.05) were increased in drug treated swim stressed mice. However HDL remained unaltered in both groups. Serum tryptophan was decreased (P<0.01) in swim stressed and nicotine treated swim stressed mice. During FST, swimming behavior was significantly increased at the cost of climbing with no change in immobility in nicotine treated mice as compared to controls. It is concluded that nicotine worsens lipid profile and glucose homeostasis in stressful situations thereby increasing the risk of cardiovascular diseases in chronic smokers and the drug induced behavioral alterations may be related to the serotonergic pathway.</jats:p
Managing diversity and gender equality in the workplace
No full textNow a day’s world is growing globalization which require more interaction among people from the diverse range of backgrounds (Green et al., n.d.). Diversity management is a method which is intended to create and helps to maintain a positive work environment where similarities and differences of people are respected and valued (Patrick and Kumar, 2012). The literature on diversity management has mostly emphasized on organization performance and organizational context of diversity related pressures, expectation, requirements and organizational outcomes in managing employee diversity and related issues (Patrick and Kumar, 2012). Diversity and equality are interconnected to each other; the main objectives of diversity and gender equality is every individual have set of rights, opportunity and fair treatment in the workplace (Diversity Inc, 2016). Moreover, the objective of the author is to highlight the importance of managing diversity and equality in the workplace. Organization capabilities to welcome managing diversity and equality (Sharma, 2016). It describes the benefits of learning policies and procedures which will ensure that an organization is optimizing the best learning capacity in the workplace (Moss, 2010). Whereas, working in diverse group or team help in achieving the goals and objectives of the workplace. The diverse workforce provide organization with competitive advantage and enhance organizational adaptability to accept change in the organization (Zanoni et al., 2010). Diversity and gender equality which define as giving equal rights to all men and women who shares the same workplace. The working style of men and women are different, but they can come with different innovative ideas and perspective at a same point. To implementing diversity; organization has faced many challenges which should be overcome to implement effective diversity in the workplace. Diversity can be improving employee performance and organization effectiveness. However, it is difficult to manage diverse work population which involves recognizing the value of differences, promote inclusiveness and battling with discrimination (Green et al., n.d.). And the challenges faced by women in the workplace. The study concludes that successful managing diversity can leads to better satisfied, more committed and better performance of the organization and would be helpful for producing an effective output (Patrick and Kumar, 2012). The study is focusing on the questions why and how a managing diversity and equality can improve the performance of any workplace. What could be the potential benefits of managing diversity in any workplace. What are challenges faced by women in the workplace. To answer these questions, author has chosen this research topic:

مومن خاں مومنؔ کے منظوم شخصی قصوں کی تنقید: ایک تجزیہ
No full textIn 18th century, Momin Khan Momin wrote autobiographical narrative poetry in consideration of the changing circumstances and trends. This depicts the fact that the poets were agglomerating imagination and reality while returning from externality to internality. The analysis of these Masnavi-like poetic tales clearly shows that the characters are now real human beings instead of genies, fairies and princesses and the elements of sentimentality and cheerfulness are more valuable than those of fight and feast. Moreover, these poetic tales of Momin are the descent of shady Urdu Masnavis and the precursor of constituting the new form of poetry.
