This paper presents a two-phase heuristic methodology aimed at the reconfiguration of a radial distribution network with the objective of minimizing the computational time. In the preliminary phase of the operation, all network switches are in a closed state, and it is proposed that a subsequent switch opening methodology be employed to achieve a configuration that approximates optimal radial char

Populärvetenskaplig sammanfattning: Kvävekoncentrationen i den gröna biomassan hos vegetation är involverad i många olika biokemiska processer i det terrestra ekosystemet. Till exempel så påverkar den fotosyntesen, förmultning och evaportanspirationen, för att nämna några. Därför är den också ofta en av grundparametrarna och drivkraften i olika ekosystem-modeller. Att mäta kvävehalten hos blad/barNitrogen in the green biomass of vegetation plays an important role in many biochemical processes in the terrestrial ecosystems, and often used as an input parameter to ecosystem models. It strongly influences photosynthetic rate, decomposition, and evaportanspiration, to name a few. Measuring nitrogen in field involves a lot of time and money, and it would be valuable if this part of the data col

AimTo fully take advantage of blood test results, comparative data are required. Today, the reference interval is a commonly used concept. This review aims to summarise the current state of reference intervals, focusing on infants.MethodsLiterature on reference percentiles (birth to 12 months of age) published from January 1950 until November 2024 was reviewed. Search terms comprised paediatric, i

INTRODUCTION: Breast cancer, a leading female cancer worldwide, can be influenced by mitochondrial dysfunction. Dysregulation of mitochondria by the nuclear genome may cause breast cancer initiation and progression. However, the comprehensive investigation of mitochondrial-related genes as prognostic marker for the overall survival of early-stage breast cancer patients is still limited.METHODS: To

This is the third of three chapters on diffusion MRI acquisition for tractography. Tractography is performed extensively in the in vivo adult brain, and sequences used for the in vivo adult brain have been covered in detail in Chapter 7. However, tractography is also performed in ex vivo human brain, in both the in vivo and ex vivo animal brain of various nonhuman species, in the human brain durin

With the advent of digitalization, the economy of the world is quickly changing itself and Indian Small and Medium Enterprises (SMEs) are the front runners. This study sheds light on how digital transformation is crucial to support the growth, competitiveness, and sustainability in the present business environment, and how digital transformation is important to the SMEs in India. To encourage SMEs

Recent years have seen a sharply rising interest in the scientific area dedicated to the study of the use of Artificial Intelligence (AI) for Cognitive Behavioral Therapy (CBT) research and applications (AI4CBT for brevity). Yet, little is known about how this interest is realized and hence the overall status, prospects, and possible challenges of AI4CBT as a field (e.g. breadth of the field, key

INTRODUCTION: Biomarkers play a crucial role in understanding Alzheimer's disease (AD) pathogenesis and treatment effects. However, comparing biomarker measures without standardization and appreciating their magnitude relative to the disease can be challenging. METHODS: To address this issue, we propose the CentiMarker approach, similar to Centiloid, which provides a standardized scale between nor

The exponential increase in medical waste production has increased the difficulty of waste management, resulting in higher medical waste dispersion into the environment. By employing a circular economy approach, it is possible to develop new materials by waste valorization. The employment of biodegradable and renewable agro-food, waste-derived materials may reduce the environmental impact caused b

The present study investigates the integration of Lean and Sustainable manufacturing (LSM) practices to improve the market competitiveness of Indian manufacturing organizations. The study aims to explore the critical role of stakeholder commitment to drive both sustainable manufacturing and lean practices with their impact on manufacturing competitiveness. In the study a survey-based approach was

Bakgrund: Den kurativa behandlingen för resektabla lokalt avancerade stadier av cancer i munhålan innefattar i regel en kombination av kirurgi och radioterapi (RT). Huruvida RT bör ges först och därefter följas av kirurgi, eller om tumören bör opereras bort först, följt av RT postoperativt, har dock inte studerats i någon större omfattning.Syfte: Denna avhandling undersöker olika aspekter av pre- Background: The curatively intended treatment for resectable locally advanced stages of oral cavity cancer (OCC) generally involves a combination of surgery and radiotherapy (RT). However, whether to apply RT first and then proceed with surgery, or to resect the cancer and subsequently administer RT, has not been extensively studied. Aims: This thesis examines various aspects of pre- versus postop

A diagonalisation procedure of the Foldy-Wouthuysen type is considered for the single-electron Dirac Hamiltonian as a basis for many-body applications. A modified procedure is suggested. In the diagonalisation procedure the Dirac equation is completely decoupled into two equations of the Pauli type. The expressions for positive- and negative-energy projection operators in the transformed basis are

The field of ultrafast science is dependent on either ultrashort laser pulse technology or ultrafast passive detection. While there exists a plethora of sub-picosecond laser pulse solutions, streak cameras are singular in providing sub-picosecond passive imaging capabilities. Therefore, their use in fields ranging from medicine to physics is prevalent. Streak cameras attain such temporal resolutio
