Grain boundary strain localization in a CdTe solar cell revealed by scanning 3D X-ray diffraction microscopy

Cadmium telluride (CdTe) solar cell technology is a promising candidate to help boost green energy production. However, impurities and structural defects are major barriers to improving the solar power conversion efficiency. Grain boundaries often act as aggregation sites for impurities, resulting in strain localization in areas of high diffusion. In this study, we demonstrate the use of scanning

Optimization of Exhaust Port and Valves for Heavy duty engines

The efficiency of combustion engines is crucial for their future development, prompting researchers to explore various factors to enhance performance. Among these factors, exhaust gases hold significant potential. Typically, exhaust gases carry about 30-40% of the engine's energy, which often remains underutilized. Although technologies like turbochargers have made progress in recovering some

Performance Measurement within Volvo Performance System - Alignment during implementation & Leading or lagging position

Title: Performance measurement within Volvo Performance System - Alignment during implementation & leading or lagging position Author: Linn Sperre Supervisors: Bertil I Nilsson, supervisor at the Faculty of Engineering, Lund University & Karin Frykholm, supervisor at Volvo Penta Background & Context: The setting of this master’s thesis takes place in an ever changing environment wh

Pituitary cyclase-activating polypeptide targeted treatments for the treatment of primary headache disorders

Objective: Migraine is a complex and disabling neurological disorder. Recent years have witnessed the development and emergence of novel treatments for the condition, namely those targeting calcitonin gene-related peptide (CGRP). However, there remains a substantial need for further treatments for those unresponsive to current therapies. Targeting pituitary adenylate cyclase-activating polypeptide

Navigating the gap between policy and practice : frontline and second-tier management perspectives and strategies in offering vocational and educational support to young adults with mental health problems

Mental health problems among young adults often lead to obstacles to completing higher education and becoming established in the labour market. It is important to offer support that can help these individuals realize educational and vocational goals in order to become self-sufficient and achieve social inclusion. Individual Placement and Support (IPS) and Supported Education (SEd) are two methods

Steroid transformation by living cells immobilized in calcium alginate

Whole cells of Arthrobacter simplex were immobilized in a living state in calcium alginate gel. The bacteria showed steroid-Δ1-dehydrogenase activity and the production of prednisolone from cortisol was investigated. The Δ1-dehydrogenase activity of the immobilized cells could be increased about ten-fold by incubation in nutrient media (e.g., containing 0.5% peptone abd 0.2% glucose). The reason f

High-resolution HLA sequencing and hypocretin receptor 2 autoantibodies in narcolepsy type 1 and type 2

Narcolepsy is a sleep disorder caused by an apparent degeneration of orexin/hypocretin neurons in the lateral hypothalamic area and a subsequent decrease in orexin/hypocretin levels in the cerebrospinal fluid. Narcolepsy is classified into type 1 (NT1) and type 2 (NT2). While genetic associations in the human leukocyte antigen (HLA) region and candidate autoantibodies have been investigated in NT1

Spatial Machine Learning for Exploring the Variability in Low Height-For-Age From Socioeconomic, Agroecological, and Climate Features in the Northern Province of Rwanda

Childhood stunting is a serious public health concern in Rwanda. Although stunting causes have been documented, we still lack a more in-depth understanding of their local factors at a more detailed geographic level. We cross-sectionally examined 615 height-for-age prevalence observations in the Northern Province of Rwanda, linked with their related covariates, to explore the spatial heterogeneity

A Multi-Objective Optimization Approach for Solar Farm Site Selection: Case Study in Maputo, Mozambique

Solar energy is an important source of clean energy to combat climate change issues that motivate the establishment of solar farms. Establishing solar farms has been considered a proper alternative for energy production in countries like Mozambique, which need reliable and clean sources of energy for sustainable development. However, selecting proper sites for creating solar farms is a function of

Learning pathways to entrepreneurial passion in venture creation programs: : A configurational study of experiential and temporal conditions

This study adopts a configurational approach to discover conditions common to graduates from venture creation programs who take a particular learning pathway to high entrepreneurial passion. Our theoretical framework identifies two primary sources of experiential learning (direct and vicarious experience) and three temporal vantage points (pre-, peri-, and post-education) conducive to such conditi
