Energy Recovery from Contaminated Biomass

This study focuses on thermal gasification methods of contaminated biomass in an atmospheric fluidized bed, especially biomass contaminated by undesirable substances in its primary use. For the experiments, chipboard waste was chosen as a representative sample of contaminated biomass. In the experiments, samples of gas and tar were taken for a better description of the process of gasifying chipboard waste. Gas and tar samples also provide information about the properties of the gas that is produced

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Webový systém na prodej předmětů s potiskem pomocí crowdfundingových kampaní

Cílem této práce bylo navrhnout a implementovat webový systém na prodej předmětů s potiskem, který zároveň umožní sbírat peníze pomocí kampaní fungujících na bázi crowdfundingu. Výsledná aplikace automatizuje a usnadňuje celý proces od návrhu potisku v integrovaném editoru přes vyhodnocení kampaně až po odeslání hotových výrobků zákazníkům. Během celého procesu tedy existuje minimum bodů, kdy je nutný administrátorský zásah zvenčí. Částí implementace bylo také napojení aplikace na externí služby, jako jsou on-line platby kartou, tiskárna či sociální sítě. Powered by TCPDF (www.tcpdf.org)The aim of this thesis was to design and implement a web system for organization of crowdfunding campaigns that are based on the sale of items with custom imprint. The implemented system automates and facilitates the whole campaign lifecycle from the design of the imprint in an integrated editor through campaign evaluation up to the distribution of final products to customers. Therefore, there is a minimum number of points where the administrator's action is required. Part of the implementation was also seamless integration with external services like on-line payments, printing house, and social networks.

Light Field Particle Effects

Cílem této práce je navrhnout a implementovat metodu kombinující light field s částicovými systémy. Jednotlivé částice jsou vykreslovány jako billboardy a jejich textura je tvořena pomocí syntetického light fieldu, který je vytvářen dynamicky za běhu. Částice také mohou využívat několik takových textur současně. Součástí práce je řada implementovaných scén demonstrujících různou funkcionalitu a měření porovnávající navrhovanou metodu se standardním 3D vykreslováním.The goal of this thesis is to propose and implement a method combining light field and particle effects. Particles are rendered as billboards and their textures are created with synthetic light field, which is dynamically generated at runtime. Particles can also use several of these textures at the same time. The thesis also includes several implemented scenes demonstrating various functionality and measurements comparing proposed method with standard 3D rendering techniques.

Design and simulation of hierarchical nets

The aim of this thesis is to implement an application for creating hierarchical nets and their simulation. The nets are composed of components interconnected by oriented edges. Every net has an associated schema which defines the appearance, behavior and way of connection of schema components. The application facilitates definition of new schemas. The simulation consists of discrete steps. During every step the behavioral programs of the activated components that are defined in the schema are processed. Simulation can be recorded and then replayed. The capabilities of the application are demonstrated on the included schemas and networks
