Foot and Lower Limb Clinical and Structural Changes in Overuse Injured Recreational Runners Using Floating Heel Shoes: Preliminary Results of a Rando…

2021

Foot-strike and the associated load rate are factors related to overuse injuries in runners. The purpose of this study was to analyse structural and functional changes in runners using floating heel running shoes, compared with runners using conventional footwear. A randomised control trial was conducted. Twenty runners with overuse injuries were followed over a 12-week gait retraining programme using floating heel running shoes or their conventional footwear. Pain was measured with pressure pain thresholds (PPTs), structural changes were measured with ultrasonography, and severity and impact of injury was scored on the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-…

Bodźce pozacenowe w kontraktach rolnych. Powiązania umowne między grupami producentów rolnych a ich pierwszymi odbiorcami w Polsce

2018

Celem artykułu jest identyfikacja stosowanych bodźców pozacenowych w umowach rolnych, które mogłyby potencjalnie skłaniać agenta do działania zgodnego z interesem kontraktora. Zastosowanie tego typu zachęt może potencjalnie minimalizować problem pokusy nadużycia ze strony agenta jeszcze w trakcie jej obowiązywania, tj. w trakcie produkcji rolnej. Dla realizacji założonego celu wykorzystano badanie własne z użyciem ankiety. Badanie empiryczne przeprowadzono wśród grup producentów rolnych działających na rynku drobiu, a przedmiotem badań były kontrakty rolne podpisane w 2014 roku. Na podstawie przeprowadzonych badań zidentyfikowano bodźce pozacenowe, które mają pomóc monitorować i łagodzić pr…

FORMATION OF MOLECULES IN ULTRACOLD ATOMIC GASES VIA QUASI-RESONANT FIELDS

2010

we study the nonlinear mean-field dynamics of diatomic molecule formation at coherent photo- and magneto-association of ultracold atoms focusing on the case when the system is initially in the all-atomic state. We show that in the limit of strongly nonlinear interaction between an ultra-cold atomic-molecular system and a quasi-resonant electromagnetic field, the molecule formation process, depending on the characteristics of the associating field, may evolve according two different scenarios, namely, weak- and strong-oscillatory regimes. In the first case the number of molecules increases without pronounced oscillations of atom-molecule populations, while in the second case high-amplitude R…

Ultrasound bioeffects in rats: quantification of cellular damage in the fetal liver after pulsed Doppler imaging

2011

Objective To determine whether pulsed Doppler examination of the ductus venosus in rat fetuses could damage exposed tissue. Methods On gestational day 18, the livers of a mean of approximately five fetuses per mother (n = 5.14, SD = 1.6), in a cohort of 35 pregnant female rats, were exposed individually to pulsed Doppler and these were considered the 'exposed group'. The remaining fetuses in each pregnant rat (n = 5.16, SD = 2.1) formed the 'control group'. We tested for 600, 300, 60, 20, 15, 10 and 3 s of exposure of the fetal ductus venosus and the damage was evaluated measuring a cell death index of apoptotic activity at 7 h post-exposure (n = 16). In addition, subgroups of mothers were …

Ultrametrisku galīgu automātu iespējas

2015

Maģistra darbā tiek pētīti ultrametriski galīgi automāti un to iespējas. Ultrametriski automāti ir līdzīgi varbūtiskiem automātiem, tikai varbūtību vietā tiek izmantotas amplitūdas, kas ir p-adiski skaitļi. Pēdējos divos gados tika veikti dažādi pētījumi, kuros piedalījās arī darba autors, par ultrametrisku algoritmu izmantošanas iespējām, ieskaitot to izmantošanu galīgajos automātos. Darbā tiek izpētītas dažādu ultrametrisku galīgu automātu tipu iespējas, salīdzinot tos ar citiem automātu tipiem. Maģistra darbā tiek salīdzinātas dažādi definētu ultrametrisku galīgu automātu valodu atpazīšanas iespējas. Ultrametriski galīgi automāti darbā tiek salīdzināti arī ar dažādu sarežģītību determinē…

UVA un UVB filtru ietekme uz saules aizsarglīdzekļu dabību

2019

Katru gadu ar melanomu saslimst arvien vairāk cilvēku. Viens no iemesliem ir ozona slāņa samazināšanās, kas rada intensīvāku ultravioletā starojuma nokļūšanu uz Zemes virsmas. Darba mērķis ir noskaidrot ultravioletā starojuma un filtru ietekmi uz cilvēkiem, respondentu sauļošanās un aizsarglīdzekļu lietošanas paradumus, sakarību starp UV filtru procentuālo daudzumu un SPF vērtību un ādas reakciju uz izveidoto aizsargkrēmu. Praktiskajā daļā tiek analizētas respondentu atbildes, veiktas SPF simulācijas, veikts un analizēts aizsargkrēma plākstera tests. Secināts, ka saules aizsargkrēmi tiek lietoti nepareizi, palielinot filtru daudzumu aizsargkrēmā, SPF vērtība palielinās, bet aizsardzība pret…

Sieviešu līdzdalība ādas vēža profilakses īstenošanā

2016

Saslimstība ar dažādām ādas vēža formām ar katru gadu pieaug. Slimība ir ārstējama un prognoze, lai atveseļoties ir laba, jo ādas vēzis ir viens no visvieglāk atklājamajiem vēža veidiem, dēļ tā, ka tas ir pamanāms, kā arī, ievērojot dažādus piesardzības pasākumus no tā ir viegli sevi pasargāt. Darba mērķis bija noskaidrot kāda ir sieviešu līdzdalība ādas vēža profilakses īstenošanā. Pētniecības uzdevumi bija: apkopot un analizēt literatūras avotus par ādas ļaundabīgiem audzējiem, to diagnostiku, ārstēšanu un profilaksi. Izmantot pētniecības darba pamatojumam Kalistas Rojas piemērošanās teoriju. Izveidot anketas jautājumus, balstoties uz pētījuma teorētisko daļu, veikt anketēšanu, apkopot ie…

Multi-Chip RFID Antenna Integrating Shape-Memory Alloys for Detection of Thermal Thresholds

2011

Low-cost wireless measurement of objects' temperature is one of the greatest expectation of radiofrequency identification technology for the so many applications in cold supply-chain control and safety assessment in general. In this context, the paper proposes a dual-chip UHF tag embedding shape memory alloys (SMA) able to transform the variation of the tagged item's temperature into a permanent change of antenna radiation features. This event-driven antenna is hence able to selectively activate the embedded microchips according to the temperature above or below a given threshold. A general design methodology for the resulting two-ports tag antenna is here introduced and then applied to pro…
