Rel stringent factors are bifunctional ribosome-associated enzymes that catalyze both synthesis and hydrolysis of the alarmones (p)ppGpp. Besides the allosteric control by starved ribosomes and (p)ppGpp, Rel is regulated by various protein factors depending on specific stress conditions, including the c-di-AMP-binding protein DarB. However, how these effector proteins control Rel remains unknown.

Sedan antiken har humanismen försökt definiera den mänskliga naturens väsen samtidigt som den placerar människan i universums centrum som ”alla tings mått”. I ett försök att omvärdera människans betydelse har det talats om ett slags transhumanistisk intersubjektivitet. Jag utgår från fysikern och feministen Karen Barads begrepp intraaktion (samspel mellan integrerade delar). Barad myntar begreppet

Economic history became a discipline with its own chair professors at the Swedish universities at the end of the 1940s. The well-known economic historian Eli Heckscher played a central role for the establishment and his work led to a stronger position for economic history in Sweden than in most other countries. However, his influence was not strong in the formation of the discipline. He always emp

Besides friction and wear, airborne particle emission has become a central parameter when evaluating disc brake performance due to its potential adverse health effects as component of ambient air pollution. The pad friction material of brake system is composed of a mixture of ingredients grouped into four material categories: abrasives, reinforcing fibres, lubricants, and fillers. Some other ingre

The current war in Ukraine has severely disrupted global food supply chains due to the significant decline in the production of grain commodities, of which Ukraine and Russia are major global suppliers. This creates problems in today’s globalised food systems. In particular, a number of countries are heavily dependent on food imports from Ukraine and/or Russia, particularly some developing nations

Hydropower is a clean and efficient technology for producing renewable energy. Assessment and forecasting of hydropower production are important for strategic decision-making. This study aimed to use machine learning models, including adaptive neuro-fuzzy inference system (ANFIS), gene expression programming, random forest (RF), and least square support vector regression (LSSVR), for predicting hy

This report relates to GIROD WP1 – “Development of a calculation model”. WP1 consists of four sub-WPs: 1.1 “Theoretical work”, 1.2 “Bond line tests”, 1.3 “Tests for calibration” and 1.4 “Calibration of model”.In WP1.1 theoretical models for rational prediction of pull out strength have been developed. The models include a very simple ideal plastic model, a linear elastic fracture mechanics model,

The paper accounts for the extent to which gender research is represented in leading archaeological journals throughout the 1980s to the present through the database Arts & Humanities Citation Index (ISI). The paper regards gender research as including gender, feminisms, masculinities,queer, intersectionality and embodiment. It is concluded that gender research, despite its alleged significanc

Almost 30 years have passed since gender studies entered archaeological discourse in earnest. What is the current status of gender research? One of the aims with this book is to contribute to answering this and other related questions. Another is to shed some light on the pasts and possible futures of gender research.Contributions deal with publication statistics in journals over the last theirty
