Global economic burden of unmet surgical need for appendicitis
2022
Abstract Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capita…
Particle tracking in a gap of aquatic vegetation meadow
2009
Aquatic vegetation considerably affects the flow field in water bodies, with influence increasing as the depth decreases. As a consequence, vegetation also affects suspended particle transport. In inshore sandy beds less than 40 m deep of the Mediterranean Sea, meadows of Posidonia oceanica are widespread. This plant is constituted by a tuft of very thin and flexible ribbon-like leaves about 1 cm wide and up to 1.5 m long; the meadow areal density can reach 1000-1200 plant/m2. Frequently, such meadows are not continuous but vegetated areas alternate with sand strips (“gaps”). The presence of such discontinuities noticeably affects the flow field and gaps can actually act as particle traps. …
Simulations of the structure and rheology of wet webs
2009
In this Thesis we modified a recently introduced model for fiber suspensions to be applicable to wet fiber networks so as to analyze by computer simulations their structural and rheological properties. These properties were compared, under tensile loading in particular, to those of wet and dry paper. The model used operated at the fiber level, where the dynamics of fiber motion were determined by fiber stiffness and fiber-fiber interactions such as friction and adhesive forces. Water surface tension, inter-fiber contact area, and moisture content all contributed to the latter force. The tensile strength of wet fiber networks could be described in terms of a very simple function of adhesion-…
Valsts prezidenta suspensīvā veto tiesība
2022
Bakalaura darba temats ir “Valsts prezidenta suspensīvā veto tiesība”. Darba mērķis ir izpētīt veto tiesības normatīvo regulējumu un piemērošanas praksi, lai uzlabotu suspensīvās veto tiesības izmantošanas efektivitāti. Latvija ir parlamentāra republika, kur Valsts prezidents nepieder nevienam no valsts varas atzariem, bet darbojas kā to līdzsvarotājs un Satversmes sargs. Lai efektīvāk īstenotu šīs funkcijas Valsts prezidentam ir piešķirtas pilnvaras, tostarp likumdošanas jomā, kur viena no izpausmēm ir suspensīvā jeb atliekošā veto tiesība. Bakalaura darba uzdevumi ir izpētīt veto tiesības ģenēzi, normatīvo regulējumu Latvijā un ārvalstīs, kā arī praktisko suspensīvās veto tiesības pieliet…
A Dynamic Framework for Sustainable Open Innovation in the Food Industry
2022
PurposeThis study aims to take a holistic perspective to investigate how open innovation supports sustainability and the contribution to the Unite Nations (UN) Sustainable Development Goals (SDGs).Design/methodology/approachThe study is based on an in-depth single case study of Andriani SpA, a leading Italian company in the food industry. The case is built by triangulating data from direct observations, documentary analysis and semi-structured interviews.FindingsThe findings show an organization that has developed its competitive advantage by adopting open innovation to embed sustainability in its strategy and business model. The case study complements the understanding of how open innovati…
Alternativas a las penas privativas de libertad de corta duración. Especial referencia a la suspensión y sustitución de la pena
2017
Desde hace siglos, el elenco de penas previsto en los distintos Códigos Penales peca de excesivamente básico y las posibles alternativas a la pena por excelencia, la prisión, son de igual modo parcas, sin que ello parezca haber preocupado demasiado al legislador. Nuestro Código Penal regula dos alternativas principales al cumplimiento de las penas privativas de libertad, las instituciones de la suspensión y la sustitución, a las que dedica, básicamente, los artículos 80 a 87 y el 89, habiendo sido derogado el 88, dedicado a la sustitución ordinaria, que ahora pasa a considerarse una modalidad de suspensión. La razón de ser de estas alternativas es tratar de evitar el efecto corruptor de la …

Improving Energy Expenditure Estimation in Wrist-Worn Wearables by Augmenting Heart Rate Data With Heat Flux Measurement
2021
Wearable electronics are often used for estimating the energy expenditure of the user based on heart rate measurement. While heart rate is a good predictor of calorie consumption at high intensities, it is less precise at low intensity levels, which translates into inaccurate results when estimating daily net energy expenditure. In this study, heart rate measurement was augmented with heat flux (HF) measurement, a form of direct calorimetry. A physical exercise test on a group of 15 people showed that HF measurement can improve the accuracy of calorie consumption estimates especially during rest and low-intensity activity when used in conjunction with heart rate information and vital backgr…
