Apgaismojuma izpēte impresionisma mākslinieku gleznojumos 4. klases vizuālās mākslas stundās
2019
Darba autore Elizabete Šulte ir izstrādājusi diplomdarbu, kura tēma ir “Apgaismojuma izpēte impresionisma mākslinieku gleznojumos 4. klases vizuālās mākslas stundās”. Mērķis ir izpētīt kā impresionisma mākslinieki gleznoja apgaismojumus darbā ar 4.klases skolēniem vizuālās mākslas stundās. Diplomdarbs ir veidots no trīs daļām. Pirmajā daļā ir izpētīta impresionisma vēsture un attīstība; otrajā daļā tika veikta teorētiska māksliniecisko izteiksmes līdzekļu izpēte, kas saistīta ar impresionisma mākslas virzienu. Diplomdarba trešajā daļā ir izveidota uzdevumu kopa, kas atbilst skolēnu vecumposmam, uzdevumu kopas aprobācija un secinājumi. Noslēguma veikti secinājumi par diplomdarbu. Diplomdarbs…
Improvizācija 5 - 6 gadīgu bērnu sadarbības prasmju pilnveidei mūzikas nodarbībās
2020
Vēsmas Ozoliņas maģistra darbā "Improvizācija 5 – 6 gadīgu bērnu sadarbības prasmju pilnveidei mūzikas nodarbībās" tika analizētas pirmsskolas pedagoģiskā procesa iespējas sadarbībā veicināt radošu pašizpausmi ar kolektīvas muzikālās improvizācijas palīdzību. Pētījuma mērķis bija izpētīt 5 – 6 gadīgu pirmsskolas vecuma bērnu sadarbības prasmju pilnveides iespējas, izmantojot muzikālo improvizāciju mūzikas nodarbībās. Pētīšanā tika izmantota teorētiskās literatūras analīze un ekspertu atzinumi par improvizācijas rotaļām. Pētījuma rezultāti pierāda pētījuma hipotēzi, ka muzikālās improvizācijas laikā tiek pilnveidotas bērnu sadarbības prasmes, ja rotaļdarbību veido kolektīvā improvizēšana. Ap…
Improvizācija kā komunikatīvo runas prasmju formēšanas un attīstības līdzeklis krievu valodas kā svešvalodas apguves sākumposmā latviešu skolā
2019
Improvizācija kā komunikatīvo runas prasmju formēšanas un attīstības līdzeklis krievu valodas kā svešvalodas apguves sākumposmā latviešu skolā: diplomdarbs. – Rīga, 2018.– 55 lpp. Pētījumā tiek vērtēta iespēja izmantot improvizāciju kā komunikatīvo runas prasmju attīstības līdzekli krievu valodas kā svešvalodas apguves sākumposmā latviešu skolā. Darbā tiek atklāta un pamatota improvizācijas izmantošanas nepieciešamība un nozīme, tiek analizētas improvizācijas kā metodiski efektīvs citvalodu komunikatīvās kompetences veidošanas līdzeklis. Diplomdarba praktiskajā daļā tiek piedāvātas metodiskas izstrādnes improvizāciju pielietošanai, kas ir papildinājums mācību grāmatai „Здравствуй, это я!” 6…
270 Increased hospital mortality in HIV-infected patients with acute coronary or cerebrovascular syndromes. Analysis from a French nationwide hospita…
2011
Background After more than two decades of the AIDS epidemic, the spectrum of HIV-associated vascular diseases has considerably evolved from infectious disease with improved survival, to premature atherosclerosis. As a consequence, acute atherosclerosis complications, such as acute coronary and cerebrovascular syndromes (ACS and CVS) are currently growing. However, only few data are available on HIV-infected patients in the setting of ACS/CVS. The aim of the present study was to determine the prevalence of HIV, as well as the characteristics and hospital case fatality of HIV-infected patients with CVS and ACS. Methods From the French nationwide hospital medical information database, data fro…
Nutritional assessment in preterm infants with special reference to body composition
2001
In recent years, improvements in care have significantly improved survival in preterm and, particularily, the very low birth weight infant (VLBW). While immediate survival can be directly related to pulmonary maturity, several studies stress the importance of timely and adequate nutrition in these high-risk infants on a short- and long-term [1]. Yet, nutritional support remains a very controversial issue in these high-risk infants. Early provision of adequate intakes may be limited by clinical instability and immaturity. At the same time, nutritional requirements and methods of nutritional assessment are not well defined. The aim of this paper is to outline some of the methods used during n…
Histamine analogues. 32nd communication: synthesis and pharmacology of sopromidine, a potent and stereoselective isomer of the achiral H2-agonist imp…
1989
Abstract Synthesis and pharmacology of sopromidine (( R )-7) and ( S )- 7 , 2 position isomers of impromidine derived from the enantiomeric α-methylhistamines, are reported. The enantiomers of 7 show high stereoselectivity at the atrial H 2 -receptor of the guinea-pig. ( R )- 7 is revealed to be a full H 2 -agonist with 7.4-fold potency relative to histamine, while ( S )- 7 is a competitive H 2 -antagonist.
Comparison of Paroxetine and Maprotiline in Minor Depression
1994
Whilst the efficacy of paroxetine has been demonstrated in MDD, its clinical utility in minor depression has not been established. This study assesses the antidepressant efficacy of paroxetine in patients meeting RDC criteria for minor depression. All patients scored 13 points on the 17-item Hamilton Depression Rating Scale (HAMD) at baseline. After a 3 day washout period, patients were randomised to receive paroxetine 20–40mg/day or maprotiline 100-150mg/day, dose being titrated according to clinical response after 3 weeks treatment at the lower doses. Assessments conducted at baseline (day 0) and at weekly intervals for 6 weeks included the 17-item HAMD, the Montgomery-Asberg Depression R…
Engineering Sr-doping for enabling long-term stable FAPb1xSrxI3 quantum dots with 100% photoluminescence quantum yield
2021
The Pb substitution in quantum dots (PQDs) with lesser toxic metals has been widely searched to be environmentally friendly, and be of comparable or improved performance compared to the lead-perovskite. However, the chemical nature of the lead substitute influences the incorporation mechanism into PQDs, which has not been explored in depth. In this work, we analyzed Sr-doping-induced changes in FAPbI3 perovskites by studying the optical, structural properties and chemical environment of FAPb1−xSrxI3 PQDs. The substitution of Pb by 7 at% Sr allows us to achieve FAPb1−xSrxI3 PQDs with 100% PLQY, high stability for 8 months under a relative humidity of 40–50%, and T80 = 6.5 m…
Photoelectrochemical Bisphenol S Sensor Based on ZnO‐Nanoroads Modified by Molecularly Imprinted Polypyrrole
2019
Molecularly imprinted polymers are important tools for the design of sensors and other molecular recognition based analytical systems. In this paper the development of a photoelectrochemical sensor for selective bisphenol determination is reported. The sensor is based on a glass/ZnO/MIP‐Ppy structure consisting of glass modified by a ZnO layer (glass/ZnO), which is functionalized by molecularly imprinted conducting polymer polypyrrole (MIP‐Ppy). The sensitivity of the sensor to bisphenol is in the range of 0.7–12.5 µm. Selectivity tests to other bisphenolic compounds are performed. Some aspects of a photoinduced response mechanism in glass/ZnO/MIP‐Ppy nanostructures are predicte…
Improving on numerical simulations of nonlinear CMB anisotropies
2015
An Adaptative-Particle-Particle-Particle-Mesh code (HYDRA) plus a ray-tracing procedure was used in [1] to perform an exhaustive analysis of the weak lensing anisotropy. Other nonlinear Cosmic Microwave Background anisotropies, such as the Rees-Sciamaand the Sunyaev-Zel.dovicheffects are also being studied by using the same tools. Here we present some advances in our study of these nonlinear anisotropies. The primary advance is due to the use of better simulations with greater particle densities and appropriate softening, although other parameters have also been adjusted to get better estimates. Thus, we improve on a previous paper [2] where the Rees-Sciamaeffect was studied with Particle-M…
