Purpose: Abdominal wall complications can be reduced by adhering to guidelines for midline laparotomy closure. However, implementation of guidelines can be challenging. To address this issue, a laparotomy closure device for swift and standardized abdominal closure was developed. The study evaluated the quality of the suture, safety, and speed of the device in a clinical setting. Methods: A prospec
Hardware distortion in large intelligent surfaces (LISs) may limit their performance when scaling up such systems. It is of great importance to model the non-ideal effects in their transceivers to study the hardware distortions that can affect their performance. Therefore, we have focused on modeling and studying the effects of nonlinear RX-chains in LISs. We first derive expressions for SNDR of a
This article elaborates on a technique for rapid real-time imaging of millimeter-wave (mmWave) power density over surfaces of several wavelengths in size. The approach involves using a screen-printed metasurface equipped with elements designed for absorption of mmWaves, along with an infrared (IR) camera to monitor temperature changes due to the absorption. By modulating the transmitted signal and
The explicit connection between the transition matrix and boundary element method integral operators is formulated. This enables the calculation of characteristic modes via eigenvalue problems involving either set of operators, leading to convenient orthogonality properties facilitating scattering analysis, solution of inverse problems, and the design of excitation fields. MATLAB implementation of
Background: Parkinson's disease is a progressive neurodegenerative disorder. Awareness and the evidence supporting the merits of palliative care (PC) approaches to people with Parkinson's disease (PwP) are increasing. Objective: This review aimed to address four key questions related to PC for PwPs and their caregivers: i) What are the indicators for timely access to PC? ii) When should PC be intr
Popular Abstract in Swedish Ett nytt och experimentellt sätt att bota eller lindra sjukdomssymptom är att, istället för att tillföra en medicin, rätta till felet på en genetisk nivå. Detta kan åstadkommas genom att överföra nya, fungerande gener, sk transgener, till celler som då börjar producera protein, som i sin tur kan ge upphov till en terapeutisk effekt. I hjärnan skulle denna typ av behandlThe use of genetically modifi ed neural stem and progenitor cells could possibly be a future strategy for repairing a brain suffering from neurodegeneration. However, so far it has proven diffi cult to maintain sufficient levels of a transferred gene in suitable cell types, after transplantation. In the present thesis I studied the silencing of transgenes induced upon differentiation of neural pro
Nanotechnology gives us materials with enhanced or completely new properties. At the same time, inhalation of manufactured nano-objects has been related to an array of adverse biological effects. We characterized particle emissions, which occurred during maintenance of common metal nanoparticle generators and contrasted the properties of the emitted particles with those originally produced by the
Popular Abstract in Swedish Alla celler behöver energi och de skaffar den på olika sätt, t. ex. från oxidering av mat eller från solljus. Adenosin trifosfat (ATP), som kallas för cellens energivaluta, kan dock inte syntetiseras direkt från mat eller ljus. Nästan alla organismer utnyttjar proteinkomplex i form av en andningskedja som sitter i membranet för att alstra en proton potential. Det kan liComplex I is the mitochondrial enzyme complex that oxidizes NADH produced in the citric acid cycle and reduces quinone in the membrane, coupled to proton pumping out of the mitochondrial matrix, creating a membrane potential. This process generates about 40% of the energy used by living organisms. High-resolution structures of complex I recently became available, but the molecular mechanism behind

Popular Abstract in Swedish Organiska syraanhydrider (OSA) är reaktiva kemikalier med låg molekylvikt som används industriellt vid produktion av olika plaster, främst så kallade polyestrar och epoxiplaster. Där används de bland annat för att tvärbinda polymerer, det vill säga molekyler bestående av långa kedjor där små enheter av samma struktur upprepas. Det har visat sig att personer som exponeraOrganic acid anhydrides (OAAs) are low molecular weight chemicals used in the industry for manufacturing of plastics such as epoxy resins. Exposure to these chemicals may lead to symptoms from the eyes and the respiratory tract in form of conjunctivitis, rhinitis and asthma. In many workers production of specific IgE antibodies are induced suggesting that a type-1 allergy mediated mechanism is inv
Denna biografi om Bob Marley är berättelsen om en liten stor man. Boken riktar sig till den som vill veta mer om Marley och hans sånger och skildrar också det samhälle och den kultur som formade Marley och reggaemusiken. Marleys dramatiska liv skildras mot bakgrund av det politiska och sociala våldet på Jamaica: hur han från att ha varit en ligist och slagskämpe i Kingston blev en symbol för kamp
There has been a dramatic change in hospital care of cardiac arrest survivors in recent years, including the use of target temperature management (hypothermia). Clinical signs of recovery or deterioration, which previously could be observed, are now concealed by sedation, analgesia, and muscle paralysis. Seizures are common after cardiac arrest, but few centers can offer high-quality electroenceph
Purpose: To investigate rates of visual field progression and factors associated with progression rate in open-angle glaucoma in clinical glaucoma care. Methods: We performed a retrospective chart review of all patients with manifest primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG) followed ≥ 5 years with ≥5 SITA Standard fields. Exclusion criteria were minimal. Demographic
A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for brain turnouts is based on data from 9 randomized trials and 1 meta-an
Water-related impacts due to change in climatic conditions ranging from water scarcity to intense floods and storms are increasing in developing countries like Pakistan. Water quality and waterborne diseases like hepatitis, cholera, typhoid, malaria and dengue fever are increasing due to chaotic urbanization, industrialization, poor hygienic conditions, and inappropriate water management. The morb
The service sector in the USA accounts for 80% of gross domestic product. However, in spite of the pivotal role of the service sector in the US economy and its impact on daily life, the level of productivity in this sector has been much lower than that of the manufacturing area. This situation has been in existence for some time, but in the current context, there are growing external pressures to
Tatrabergen, som ligger i västra delen av Karpaterna, har upplevt flera nedisningar under kvartärtiden. Avsättningarna i sluttningarna längs bergens södra sida har klassificerats som glacifluviala, baserat på geomorfologi, men har inte undersökts i detalj tidigare. Det här projektet fokuserar därför på att etablera avsättningshistoria och -processer samt avlagringarnas ålder i ett grustag i Biely The Tatra Mountains have had several glaciations during the Quaternary. The deposits located in the southern foothills were classified as glacifluvial, based on geomorphology, but its sediments have not been studied in detail. Therefore, this project focused on establishing the depositional history, processes, and age of the deposits in a gravel pit, located in the Biely Váh valley in these foothi
Låg tillgänglighet till elektricitet är ett stort problem i Kenya, framförallt på landsbygden, och det förväntas fortfarande dröja flera decennier innan elnätet har nått ut till alla delar av landet. Detta innebar att det finns ett stort behov av andra lösningar som kan förse dessa områden med elektricitet. En av dessa lösningar är Solar-Home-System (SHS), ett system som kan ge elektricitet till lA problem in Kenya is the lack of access to electricity, mainly in rural areas. It will take many decades for the main grid to reach all rural areas wherefore several off-grid electrification options have been put forward to solve this issue. One of them is the Solar Home System (SHS), which is an off-grid solar product that can be used for applications such as lamps, radios, TVs and charging mobi
