Construction and characterization of models of hypercrosslinked polystyrene

2012

A simple algorithm involving classical molecular dynamics (MD) simulations is here suggested to build up models of hypercrosslinked polystyrene showing macroporous structure. The algorithm is composed by three consecutive stages: MD simulation of a single polystyrene coil, crosslink formation, and finally relaxation of the structure. The models, which are differentiated by the crosslinker concentration in the initial polystyrene chain, can be characterized by employing tools of the small angle neutron scattering analysis and procedures associated to the crosslinking algorithm, which allows one to discriminate among the different kinds of crosslinks between phenyl rings and to calculate the …

Performance Evaluation of the IEEE 802.16 ARQ Mechanism

2007

The IEEE 802.16 technology defines the ARQ mechanism that enables a connection to resend data at the MAC level if an error is detected. In this paper, we analyze the key features and parameters of the ARQ mechanism. In particular, we consider a choice for the ARQ feedback type, a scheduling of the ARQ feedbacks and retransmissions, the ARQ block rearrangement, ARQ transmission window and ARQ block size. We run a number of simulation scenarios to study these parameters and how they impact a performance of application protocols. The simulation results reveal that the ARQ mechanism plays an important role in transmitting data over wireless channels in the IEEE 802.16 networks.

Meldingsovervåkning – en sikkerhet ved sending av elektroniske henvisninger : En kvantitativ studie om ulike faktorers påvirkning på meldingsovervåkn…

2018

Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Using electronic messages is a necessary tool for healthcare providers to be able to perform their work more efficiently. Regarding this, it is very important to maintain an overview and control of the messages that is transmitted between the participants. In order to ensure that a business has procedures for handling application receipts related to electronic messaging, there is a regulatory requirement for how the business should perform this work, both organizational and technical. The purpose of this study is to gain insight into how doctor’s offices in Agder comply with the requirements imposed by the Norwe…

Neiroiekaisuma biomarķieru ekspresijas izmaiņas streptozotocīna Alcheimera slimības modelī žurkām ar muscimolu

2016

Alcheimera slimība ir biežākā neirodeģeneratīvā slimība mūsdienu sabiedrībā, ar tendenci slimnieku skaitam ar katru gadu pieaugt. Sarežģītās diagnostikas un neefektīvās farmakoloģiskās terapijas dēļ, šo slimību ir grūti kontrolēt. Pētnieki nodarbojas ar Alcheimera slimības pirms-demences diagnostikas metožu un veiksmīgas farmakoloģiskās terapijas atklāšanu. Balstoties uz iepriekš veiktiem pētījumiem par GABAA agonista muscimola (0,01 un 0,05 mg/kg) spēju samazināt neiroiekaisumu, streptozocīna (STZ) izraisītā Alcheimera slimības modelī žurkām [Mareš P., et al. 2014], [Ding Y., et al. 2015], šajā pētījumā tika apskatīta un analizēta neiroiekaisuma biomarķieru ekspresija post mortem žurku sma…

Bērnu hospitalizācijas iemesli laika periodā no 2012.-2015.gadam

2016

Kā zināms, ik dienu ar neatliekamās medicīniskās palīdzības dienestu, ģimenes ārsta vai cita speciālista nosūtījumu, vai paši stacionārā ar sūdzībām ierodas pacienti, taču ik gadu šie iemesli mainās- kādas saslimšanas skaists pieaug, kādas samazinās. Ikvienam, jo sevišķi bērnu vecākiem ir svarīgi zināt, kādas tendences ik gadu pieaug, lai zinātu, kam ikdienā pievērst lielāku uzmanību- uzturam, fiziskām aktivitātēm, ikdienas paradumiem vai kam citam. Bakalaura darba tēma: „Bērnu hospitalizācijas iemesli laika periodā no 2012.- 2015. gadam”. Darba mērķis: Iegūt datus par bērnu hospitalizācijas iemesliem laika periodā no 2012. -2015. gadam.

Iemesli vegānisma kā dzīvesstila izvēlei: Rīgas piemērs

2018

Bakalaura darbā „Iemesli vegānisma kā dzīvesstila izvēlei: Rīgas piemērs” pētīts tas, kā vegānisms integrējas Rīgā dzīvojoša vegāna dzīvē, kā arī galvenie iemesli kļūšanai par vegānu. Pētījuma mērķis ir noskaidrot Rīgā dzīvojošo vegānu iemeslus izvēlēties vegānismu kā dzīvesstilu. Darba apakšmērķis ir noskaidrot mediju konstruēto attieksmi pret vegānismu. Kā pētījuma teorētisko ietvaru autore izmantoja racionālās izvēles teoriju, kā arī rakstus un veiktos pētījumus par vegānismu. Lai sasniegtu pētījuma mērķi, autore izmantoja kvalitatīvo pētījuma metodi - veica 15 daļēji strukturētās intervijas ar Rīgā dzīvojošajiem vegāniem. Papildus tam autore vēlējās noskaidrot ziņu mediju konstruēto att…

The insect nephrocyte is a podocyte-like cell with a filtration slit diaphragm.

2008

The nephron is the basic structural and functional unit of the vertebrate kidney. It is composed of a glomerulus, the site of ultrafiltration, and a renal tubule, along which the filtrate is modified. Although widely regarded as a vertebrate adaptation, 'nephron-like' features can be found in the excretory systems of many invertebrates, raising the possibility that components of the vertebrate excretory system were inherited from their invertebrate ancestors. Here we show that the insect nephrocyte has remarkable anatomical, molecular and functional similarity to the glomerular podocyte, a cell in the vertebrate kidney that forms the main size-selective barrier as blood is ultrafiltered to …

Dyslipidemia management with medical nutrition therapy: current status and perspectives

2013

In Italy, patients with dyslipidennia account for 15-20% of the adult population with major healthcare and socio-economic impact. According to the ESC/EAS guidelines for the management of dyslipidemias, desirable cholesterol and triglyceride levels can be achieved with a synergy between drug treatment and adequate diet therapy. However, what diets should be adopted? In this review article, different types of dietary treatments are compared, with a special focus on diet education. The new scientific frontier of nutrigenetics is also discussed.

Anti-inflammatory Therapies for Cardiovascular Disease: Signaling Pathways and Mechanisms

2019

Cardiovascular diseases (CVD) are the clinical manifestation of atherosclerosis, a chronic inflammatory disease promoted by several risk factors such as dyslipidemia, type 2 diabetes mellitus, hypertension, and smoking. Acute CVD events are the result of an unresolved inflammatory chronic state that promotes the rupture of unstable plaque lesions. Of note, the existing intensive therapies modify risk factors but do not prevent life-threatening recurrent ischemic events in high-risk patients, who have a residual inflammatory risk displayed by increased C-reactive protein (CRP) levels. Better understanding of the role of innate and adaptive immunity in plaque development and rupture has led t…
