The bamboo species Guadua angustifolia is a natural functionally graded material with a high potential to help solving the housing deficit in Latin American countries. Bamboo plantations also play an important role to help reducing the devastation of tropical forests. Many studies have demonstrated the excellent mechanical properties of bamboo along the length of the culm. However, other propertie

Background: Appendicitis is the most common disease requiring acute abdominal surgery in children, yet the pathogenesis of appendicitis is not fully understood. It can be challenging to diagnose appendicitis clinically, especially in young children, leading to high rates of initial misdiagnosis. It is not clear why some children are affected by a complicated disease course while others recover spo

This book studies the interplay of economic philosophy and moral conduct as reflected in the writings of one of the most renowned scholars in Islamic history, Abū Ḥāmid al-Ghazālī (d. 1111). Al-Ghazālī contributed to Islamic theology, philosophy, and Sufism but is also regarded as one of the forerunners of classical economic thought in Islamic tradition.Al-Ghazālī made seminal contributions to the

This thesis addresses the critical issue of design and development of products like production machines for SMEs and rural communities as an essential capability to foster local technology development within the innovation systems of Latin America. What is studied and discussed in this thesis is the pre-requisites for effective application of design and development methods, like design thinking fo

Increasing concern regarding climate change and environmental sustainability have driven research regarding the development of innovative solutions for CO₂ mitigation and biomass utilization. This thesis explores the catalytic conversion of CO₂ and lignin into valuable chemicals, as a promising approach to achieving carbon neutrality and enhancing the circular economy. The study focused on two key

År 2022 antogs förordningen Digital Markets Act (DMA) av Europeiska unionen. Syftet är att säkerställa konkurrensbarhet och rättvisa på digitala marknader, särskilt genom att reglera beteendet hos mycket stora företag som kan utnyttja sin ekonomiska ställning till nackdel för konkurrenter. Sådana företag benämns som grindvakter (gatekeepers) enligt DMA och känneteck-nas av sin förmåga att kontrollIn 2022, the Digital Markets Act (DMA) entered into force as a regulation adopted by the European Union with the objective of safeguarding contestability and fairness in digital markets, in particular by addressing the conduct of very large undertakings that are able to leverage their economic position to the detriment of competitors. Such undertakings are designated as “gatekeepers” under the DMA

Sammanfattning Denna uppsats behandlar fastställandet av föräldraskap i svensk rätt när barn tillkommit genom surrogatarrangemang utomlands. Surrogatmoderskap är inte tillåtet inom svensk hälso- och sjukvård, men internationella surrogatarrange-mang förekommer och medför att barn födda genom sådana arrangemang regelbundet möter den svenska rättsordningen. I avsaknad av särskild lagstift-ning på omSummary This thesis reviews the establishment of legal parenthood in Swedish law in cases where children are born through international surrogacy arrangements. Despite the fact that surrogacy is not authorized within the Swedish healthcare system, such arrangements exist abroad with increasing frequency, resulting in children commonly entering the Swedish legal order. In the absence of distinct le

A wideband, compact monopolar patch antenna with an inherent filtering response is presented in this paper. By employing a slot-assisted mode-tailoring technique, the field distributions of several higher-order modes at the patch center are engineered to produce a stable monopolar radiation pattern with enhanced bandwidth. The closed-form analysis indicates that increasing the current intensity at

INTRODUCTION: Amyloid-positron emission tomography (PET) is pivotal to Alzheimer's management, with the Centiloid standardizing measurements across tracers. AMYPAD trials (Diagnostic and Patient Management Study [DPMS] and Prognostic and Natural History Study [PNHS]) aimed to validate robust quantification in clinical settings. We report our comprehensive approach to amyloid-PET implementation, co

The stable isotope ratios of carbon (δ13C(CH4)) and hydrogen (δ2H(CH4)) in methane (CH4) from atmospheric air samples provide a tracer that can help distinguish the relative contribution of emission sources. These can be continuously measured at atmospheric monitoring stations by optical isotope ratio spectrometer (OIRS) instruments, providing data that is complementary to isotope ratio mass spect
