The most efficient way of building up energy in an oscillating system is to do it in phase with a resonant frequency of the system. If the resonant frequency changes for any reason this is difficult to obtain with a static frequency generator. It is of course possible to sweep over a frequency interval to find the maximum repeatedly, but a frequency sweep takes time and it is performed at discrete
OBJECTIVE: We sought to study changes in morphology and stent-graft configuration of descending thoracic aortic aneurysms after endovascular repair. METHODS: Twenty-three patients treated with custom-made stent-grafts were studied. The stent-graft consisted of continuous, stainless-steel Z stents mounted within a polyester graft. In the last 11 cases the stents were interconnected with 3 longitudi
Previous in vitro studies have implied that the Wnt-5a gene plays a role as a tumor suppressor. To explore the clinical relevance of this concept, 96 primary invasive breast carcinomas were stained with a novel anti-Wnt-5a antibody. Loss of Wnt-5a protein expression, evident in 44% of the invasive ductal carcinomas (n = 59), was significantly associated with higher histological grade (P = 0.01) an
Research show that human trafficking is one of the fastest growing criminal industries today, after narcotics and illegal arms trade (The Polaris Project 2014). The most common victims of human trafficking are stated to be women and children (UNODC 2012). According to the UNICEF (2007), 1,2 million children are estimated to be exposed to trafficking for various exploitative purposes every year aro
Denna uppsats har haft som syfte att undersöka vad som sker när makars ekonomiska enhet plötsligt upphör genom att en av makarna avlider. Det är många praktiska åtgärder rörande bouppteckning, bodelning och arvskifte som kan försvåras genom gällande lagstiftning. Efterlevande make ärver med försteg framför gemensamma bröstarvingar enligt 3 kap 1 § ÄB. I de fall där det finns särkullbarn eller univThe main purpose of this thesis is to describe what happens when the economic unit of spouses ceases due to death. There are many practical actions regarding estate inventory, division of property and distribution of the estate that are complicated. The surviving spouse inherit his or her spouse’s estates before direct heirs, regulated in ÄB 3rd chapter 1 §, the Swedish inheritance code. Children
Accelerometer technology was used to evaluate behaviours in the teleost ambush predator pike Esox lucius foraging on crucian carp Carassius carassius. Automated rule-based estimates of prey-size determined handling time were obtained and are compared with video-recorded behaviours. Solutions to tag attachment and the limitations imposed by battery-time and data-logging capacities are evaluated.
In many studies, data from transient or quasi steady-state solute transport experiments are modeled using steady-state models. Few investigations, however, have been carried out to verify the validity of this approach. In this paper, we study the effects of water application frequency on the parameters derived using steady-state models. Bromide transport was studied in an undisturbed soil column o
Explanations of leaf size variation commonly focus on water availability, yet leaf size also varies with latitude and elevation in environments where water is not strongly limiting. We provide the first conclusive test of a prediction of leaf energy balance theory that may explain this pattern: large leaves are more vulnerable to night-time chilling, because their thick boundary layers impede conv
Title: Are we born gifted or can we learn and teach our children to be musically interested? The aim of this study is to evaluate how we influence the development of musicality in children. The study included 30 persons divided into three groups (ten members in each group). Group 1 consisted of pregnant women. Group 2 consisted of parents of babies age 0 to 1 year old and group 3 teenage parents.
Sveriges självbild som länge varit lyckligt befriad från svågerpolitik, maktmissbruk och pengar under bordet har under det senaste decenniet fått sig en törn. Stora svarta rubriker på löpsedlar har uppmärksammat oss på att korruption och mutor även förekommer i vårt trygga demokratiska samhälle. För att på ett effektivt sätt komma åt detta krävs ett fungerande regelverk, något som haltar då det koThe Swedish Bribery Legislation in use today was written in 1977 and is consequently neither completely modern nor crystal clear. There are no legal definitions on what constitutes a bribe or what is giving rise to corruption and the verdicts are instead made on a case by case basis. The Swedish Bribery Legislation has over the years received a lot of criticism as it is seen as unpredictable and d
The aim of this study was to find an understanding of elderly care staff´s views on documentation requirement and documentation as a task and also to examine managers views on implementation of new tasks. We wanted to enter more deeply into the tension between the managers´ expectations, based on the set of goals made from politicians, and the response of this from the elderly care staff and what
Background: Accurate volumetry and imaging characterization of chronic subdural hematoma (cSDH) are essential for prognostication and treatment planning, but manual assessment is time-consuming and therefore underutilized. Methods: We retrospectively analyzed preoperative non-contrast CT (NCCT) scans of 257 patients undergoing first-time surgery for uni- or bilateral cSDH. Hematoma volumes were
Aims/hypothesis: The aim of this work was to investigate whether baseline uric acid (UA) is associated with future complications among young individuals with newly diagnosed type 1 diabetes. Methods: UA levels were analysed in individuals, aged 15–34 years with newly diagnosed type 1 diabetes, from the nationwide Diabetes Incidence Study in Sweden (DISS) cohort to assess the relationship with macr
Aluminum is a promising carbon-free energy carrier, but advancing its use requires detailed understanding of its combustion behavior at the single-particle level. Measuring the transient surface temperatures of burning aluminum droplets is particularly challenging due to their small size, extreme temperatures, and fast dynamics. In this work, we demonstrate a multispectral pyrometry approach based
Potassium (K) is one of the main and most hazardous trace species released to the gas-phase during thermochemical conversion of biomass. Accurate experimental data and models of K release are needed to better understand the chemistry involved. Tunable diode laser absorption spectroscopy (TDLAS) is used for simultaneous real-time in situ measurements of gas-phase atomic K, water (H2O) and gas tempe
Evaluation of incidence and survival of patients with borderline ovarian tumors in Sweden MATERIAL AND METHODS: All women diagnosed with borderline ovarian tumor in the Swedish Cancer Register 1960-2007 (n=6,252) combined with follow-up in the Swedish Death Registry to 1 July 2009 were included. Estimation of age-standardized relative survival rate according to time periods for diagnosis RESULTS:
Popular Abstract in Swedish Aerob kapacitet, i dagligt tal konditionen, är den maximala förmågan att utföra ett fysiskt arbete karaktäriserat av den maximala syreförbrukningen (V'O2max). Detta maximala arbete kan endast utföras en begränsad tid, till stor del beroende på en tilltagande anaerob metabolism, vilken bl.a. avspeglas som en ökning av utvädrat CO2 i lungorna. Längre tids arbete kan emellDifferent methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. Comparison of the rating with an exercise test in a group of women revealed that a correction based on age more accurately predicted the maximal exercise capacity. An
Objective: To evaluate whether upregulation of liver and muscle uncoupling protein 2 (UCP-2) is an acute phenomenon in obstructive jaundice and associated with secondary metabolic effects. Methods: Male Sprague-Dawley rats were divided into four groups bile duct ligated (BDL) and sham-operated pair-fed (PF), ad libitum fed (AL), and controls BDL. PF. and AL rats were further divided into subgroups
Background: Laparoscopic herniorrhaphy has emerged as a recognized operative method for inguinal hernia repair. This study compared the short-term results of two tension-free methods of repair: totally extraperitoneal (TEP) laparoscopic patch repair and the open Lichtenstein mesh technique. Methods: A total of 1513 men from 11 hospitals who presented with a primary unilateral inguinal hernia were
